Description

The present invention relates to, for example, an end cap that surrounds the end of a covered electric wire in which a conductor made up of a plurality of core wires is exposed from an insulation coating.

For example, coated wires, in which a conductor made up of a plurality of core wires is coated with an insulating coating, are used as electric wires constituting wire harnesses and the like that are routed in vehicles. At the end of this covered wire, a conductor is exposed from the insulating coating in order to connect to electronic equipment, a battery, or the like to which the wire is connected. However, if the conductor remains exposed at the terminal, there is a risk of a short circuit, so in order to insulate the terminal, a terminal cap that surrounds the terminal is used for such covered wires.

For example, Patent Document 1 discloses that a cylindrical cover body with one end closed is placed over the terminal of a covered electric wire, and a tongue piece provided at the other end of the cover body is fixed to the coated electric wire with tape to surround the terminal. A terminal cap is disclosed. According to this terminal cap, since the terminal cap is fixed to the covered electric wire with tape, the terminal cap is firmly fixed to the covered electric wire, and it is said that the risk of short circuit can be reduced.

However, in order to attach such a terminal cap to a covered electric wire, a complicated operation of winding a tape while holding the terminal cap is required. Furthermore, this type of work must be done manually, which poses a problem in the workability of the installation work.

In view of the above problems, the present invention aims to provide a terminal cap that can be easily attached and that can reliably prevent short circuits.

The present invention is an end cap that surrounds an end of a covered electric wire in which a conductor made up of a plurality of core wires is exposed from an insulation sheath, and accommodates a part of the tip side of the insulation sheath and an exposed conductor exposed from the insulation sheath. a cap body that is pivotally connected to the cap body and a cover body that closes an opening of the cap body; A welded part to which the core wire is welded , and a wide tip part on the distal side of the welded part are formed, and the cap body includes a tip accommodating part that accommodates the tip part, and a tip part that accommodates the welded part and , a welding part accommodating part narrower than the tip accommodating part, and a covering part accommodating part accommodating a part of the tip side of the insulating coating and wider than the welding part accommodating part are provided along the axial direction; , the cover body is provided with a tip cover body that closes the openings of the tip accommodating part and the welding part accommodating part, and a covering part cover body that closes the opening of the coating part accommodating part, and the cover body and a fixing part for fixing the tip cover body that closes the opening of the welded part accommodating part to the cap main body.

The narrow width mentioned above does not only mean that the width of all parts is narrower than the width of every part of the part to be compared, but also that the width of all parts is narrower than the maximum width of the part to be compared. Also includes. Similarly, wide as mentioned above does not mean only that the width of all parts is wider than the width of any part of the parts being compared, but that the width of all parts is wider than the minimum width of the parts being compared. This includes wide areas.

According to this invention, the terminal cap can be easily attached and short circuits can be reliably prevented.

Specifically, in order to prevent short circuits, it is necessary to prevent the terminal cap from accidentally falling off. In particular, the terminal cap is intended for the covered electric wire in which the exposed conductor has a welded part welded in the middle part and a wider tip part on the distal side of the welded part, and prevents short circuits. Therefore, it is necessary to prevent such falling off from the covered wire.

On the other hand, since the welding part accommodating part is narrower than the tip accommodating part, the wide tip part of the exposed conductor can function as a retainer for the narrow welding part accommodating part. . Thereby, movement of the terminal cap in the axial direction can be restricted. Furthermore, since a fixing part is provided for fixing the tip cover body to the cap body, this fixing part can effectively prevent the tip cover body from coming off.

Moreover, the movement of the terminal cap in the axial direction can be restricted simply by accommodating the exposed conductor in the tip accommodating part and the welding part accommodating part, and since the fixing part is provided on the terminal cap, it is possible to restrict the movement of the terminal cap in the axial direction. There is no need to use material tape or the like. Therefore, the installation work can be facilitated.

In this way, the movement of the terminal cap in the axial direction is restricted and the distal end cover body is also prevented from coming off, so that it is possible to reliably prevent the terminal cap from accidentally falling off, and also to prevent the terminal cap from being attached. Makes work easier. Therefore, according to the present invention, the terminal cap can be easily attached and short circuits can be reliably prevented.

As an aspect of the present invention, a plurality of the fixing parts may be provided.

According to this invention, even if some force acts on the terminal cap and one of the plurality of fixing parts is released from the fixed state, the distal end cover body is prevented from coming off by the remaining fixing parts. It can be prevented. Therefore, it is possible to more reliably prevent the terminal cap from falling off inadvertently.

Further, as an aspect of the present invention, the fixing part includes a first fixing part that fixes the tip cover body to at least one of the tip accommodating part and the welding part accommodating part, and a second fixing part having a different fixing manner. may be provided.
The above-mentioned differences in the fixing methods include not only fixing methods such as locking and fitting, but also the specific fixing structure and fixing method, such as what kind of locking structure is used when the fixing method is locking. In the case of locking, the locking direction includes different fixing directions, etc., and the type and direction of the force applied to release the fixed state by the fixed part, such as rotation and pulling, also differs, and there are different types and This includes cases where the fixed state cannot be released unless a directional force is applied.

According to this invention, it is possible to reliably prevent the terminal cap from accidentally falling off.

Specifically, even if some force acts on the terminal cap and, for example, the second fixing part is released from the fixed state, the first fixing part is fixed in a different manner from the second fixing part. , the fixed state will not be released even if the same type of force is applied. In other words, unless a plurality of types of forces act, both the first fixing part and the second fixing part can be kept in a fixed state. Therefore, it is possible to reliably prevent the terminal cap from accidentally falling off.

Further, as an aspect of the present invention, the first fixing part is provided on the tip cover body, and is latched and fixed to at least one of the tip accommodating part and the welding part accommodating part, and the second fixing part may be provided in at least one of the tip accommodating portion and the welded portion accommodating portion, and may be latched and fixed to the tip cover body.

Alternatively, as an aspect of the present invention, the first fixing part and the second fixing part have a structure that is fixed by being locked to a part of the other party, and the first fixing part and the second fixing part are locked to each other. The directions may be different.

According to these inventions, in order to remove the tip cover body, a complicated operation is required to release the locked state of both the first fixing part and the second fixing part, which are locked in different locking directions. This makes it possible to more reliably prevent the terminal cap from accidentally falling off while using a locking fixing method that does not require complicated work.

Further, as an aspect of the present invention, a covering part fixing part is provided for fixing the covering part cover body that closes the opening of the covering part accommodating part to the covering part accommodating part, and the covering part cover body is attached to the tip cover body.

It may function as one of the fixing parts that fix the cover body to the cap body.

According to the present invention, the movement of the tip cover body is regulated by the covering part cover body via the regulated part, so in order to remove the terminal cap, for example, the fixed state of the covering part fixing part must be released. However, a stepwise operation is required to release the fixed state of the other fixed portions of the tip cover body. Thereby, it is possible to more reliably prevent the terminal cap from accidentally falling off.

Further, as an aspect of the present invention, the covering part cover body is arranged in a direction perpendicular to the axial direction with respect to the covering part accommodating part, and is configured to be pivotable by a hinge along the axial direction. The tip cover body may be arranged in the direction orthogonal to the tip accommodating portion and the welding portion accommodating portion, and may be configured to be pivotable by a hinge along the axial direction.

According to the present invention, the end cap can be attached to the covered electric wire by a simple operation of pivoting the tip cover body and the covering portion cover body by respective hinges along the axial direction.

Further, as an aspect of the present invention, the coating portion cover body and the tip cover body may be arranged on opposite sides of the cap body in the orthogonal direction.

According to this invention, it is possible to more reliably prevent the terminal cap from accidentally falling off.

More specifically, since the sheathing part cover body and the tip cover body are arranged on opposite sides of the cap body in the orthogonal direction, the rotational direction for opening and closing the sheathing part cover body and The direction of rotation for opening and closing the tip cover body can be reversed.

Therefore, in order to open the tip cover body, at least after a rotational force for opening and closing the sheathing part cover body is applied, a rotational force in the opposite direction must be applied. No. In other words, forces must be applied in stages and in greatly different directions, which can complicate the force that must be applied to open the tip cover body.

Therefore, it is possible to more reliably prevent the terminal cap from accidentally falling off.

Further, as an aspect of the present invention, the covering part cover body is arranged in a direction perpendicular to the axial direction with respect to the covering part accommodating part, and is configured to be pivotable by a hinge along the axial direction. The distal end cover body may be disposed at the distal end of the distal end accommodating portion in the axial direction, and may be configured to be pivotable by a hinge along the orthogonal direction.

According to this invention, it is possible to more reliably prevent the terminal cap from accidentally falling off.

Specifically, the covering part cover body is configured to be pivotable by a hinge along the axial direction, and the tip cover body is configured to be pivotable by a hinge along the orthogonal direction. The direction of rotation for opening and closing the covering portion cover body and the direction of rotation for opening and closing the tip cover body can be made perpendicular to each other.

Therefore, in order to open the tip cover body, at least after a force in a rotational direction for opening and closing the covering part cover body is applied, a force in a rotational direction perpendicular to this must be applied. First, forces must be applied in stages and in greatly different directions, which can complicate the force that needs to be applied to open the tip cover.

Therefore, it is possible to more reliably prevent the terminal cap from accidentally falling off.

Further, as an aspect of the present invention, a wide part is formed between the welded part of the exposed conductor and the tip part of the insulating coating, and the width gradually becomes narrower toward the narrower welded part, A portion that covers the width portion may be provided on the side of the covering portion cover body in the tip cover body.

As shown in FIGS. 1A and 1B, the terminal cap 1 is attached to a covered electric wire 100 in which a conductor made up of a plurality of core wires is covered with an insulation coating 300. Specifically, the conductor is attached to a portion of the terminal 110 of the covered electric wire 100 that is exposed from the insulation coating 300, and surrounds the terminal 110. That is, by surrounding the terminal 110 with the exposed conductor using the terminal cap 1 and insulating the terminal 110, a short circuit due to the terminal 110 is prevented.

In addition, hereinafter, the direction corresponding to the longitudinal direction of the covered electric wire 100 is referred to as the axial direction L, the direction orthogonal to the axial direction L and corresponding to the vertical direction in FIG. 2(a) is referred to as the width direction W1, and the axial direction The direction perpendicular to L and corresponding to the up-down direction in FIG. 2(b) is defined as the vertical width direction W2. Moreover, when referring to the axial direction L, the width direction W1, and the vertical width direction W2 with respect to the terminal cap 1, each refers to a direction that coincides with each direction when the terminal cap 1 is attached to the covered electric wire 100.

Also, when simply saying "width", it refers to both the horizontal width and the vertical width, and when simply saying "wide" or "narrow", it means that both the horizontal and vertical widths are wide or narrow.

At the terminal 110 of the covered wire 100 to which the terminal cap 1 is attached, the exposed conductor 200 is exposed from the insulation coating 300, as shown in FIGS. 2(a) and 2(b). In this exposed conductor 200, there is a welded part 210 welded in the middle part, a tip part 220 which is a part on the distal side of the welded part 210, and a tip part of the welded part 210 and the insulating coating 300 (accommodated part 301 to be described later). It is comprised of a width part 230 between the two parts. The exposed conductor 200 has a constricted shape in which the welded part 210 is narrower than the tip part 220 and the width part 230.

Specifically, the welded portion 210 is a portion where the exposed conductors 200 are welded to each other, and has a uniform width and length in the axial direction L.
The distal end portion 220 has a tapered portion 221 that is continuous with the distal end side of the welded portion 210 and becomes wider toward the distal end, and the portion on the distal side of the tapered portion 221 is also wider than the welded portion 210. In other words, the tip portion 220 is wider than the welded portion 210.

The width portion 230 has a tapered shape that gradually becomes narrower toward the narrower weld portion 210, and the width portion 230 is also wider than the weld portion 210. In this way, the exposed conductor 200 has a constricted shape in which the welded portion 210 is narrower than the welded portion 210 and the width portion 230, which are the portions on both sides in the axial direction L of the exposed conductor 200.

The terminal cap 1 is attached to a plurality of covered electric wires 100. Specifically, the plurality of covered wires 100 are bundled at the portion covered with the insulation coating 300, and the welded portion 210 is a portion where the exposed conductors 200 of the plurality of conductors are welded together. Then, the terminal cap 1 is attached to a terminal 110 in which a plurality of covered wires 100 are bundled and a plurality of exposed conductors 200 are welded together.

As shown in FIG. 3(a), the terminal cap 1 is pivotally connected to a cap body 10 that accommodates a portion of the distal end side of the insulation coating 300 and the exposed conductor 200. It also includes a cover body 20 that closes the opening of the cap body 10. In addition, below, a part of the front end side of each insulation coating 300 accommodated in the cap main body 10 will be collectively referred to as the accommodated part 301.

The cap body 10 includes a tip accommodating portion 11 that accommodates the tip portion 220, a welded portion accommodating portion 12 that accommodates the welded portion 210, a width portion accommodating portion 13 that accommodates the width portion 230, and a accommodated portion 301. A covering portion accommodating portion 14 is provided along the axial direction L. These tip accommodating portion 11, welding portion accommodating portion 12, width portion accommodating portion 13, and covering portion accommodating portion 14 are integrally constructed.

The cover body 20 also includes a distal end cover body 21 that closes the openings of the distal end accommodating part 11 , welded part accommodating part 12 , and width part accommodating part 13 , and a covering part cover body 22 that closes the opening of the covering part accommodating part 14 . is provided.

The distal end cover body 21 is disposed at the distal end of the distal end accommodating portion 11 in the axial direction L, and is configured to be pivotable by a hinge along the width direction W1 perpendicular to the axial direction L.
The covering part cover body 22 is arranged in the width direction W1 perpendicular to the axial direction L with respect to the covering part accommodating part 14, and is configured to be pivotable by a hinge along the axial direction L.

As a result, with the covered electric wire 100 accommodated in the cap body 10, the tip cover body 21 is pivoted about the width direction W1 by the hinge, and the tip accommodating portion 11, the welding portion accommodating portion 12, and the width portion accommodating portion 13 are rotated. can close the opening. Moreover, the opening of the covering part accommodating part 14 can be closed by pivoting the covering part cover body 22 around the axial direction L using a hinge. Thereby, the terminal cap 1 can cover the terminal 110.

Further, specific shapes of the cap body 10 and the cover body 20 will be explained. The cap body 10 and the cover body 20 have shapes that can accommodate the exposed conductor 200 and the accommodated portion 301 when put together. The cap body 10 and the cover body 20 have shapes that are symmetrical with respect to the opening surface (a surface that is perpendicular to the vertical width direction W2 and in contact with the opening edge of the cap body 10). Therefore, the cap body 10 has a box-like shape that accommodates the lower half portion of the exposed conductor 200 and the accommodated portion 301 in the vertical width direction W2, and the cover body 20 has a It has a box-like shape that accommodates the upper half portion in direction W2.

That is, the tip accommodating part 11, the welding part accommodating part 12, the width part accommodating part 13, and the covering part accommodating part 14 are arranged in the longitudinal and width directions of the tip part 220, the welding part 210, the width part 230, and the accommodated part 301, respectively.

It is formed in a box shape that receives the upper half portion in the width direction W2.

Furthermore, in the cap body 10, the welding part accommodating part 12 is made narrower than the tip accommodating part 11 (more specifically, the maximum width of the tip accommodating part 11), and the welding part accommodating part 12 (more specifically, the welding part accommodating part 12 is The width of the width part accommodating part 13 and the covering part accommodating part 14 are made wider than the minimum width of the part accommodating part 12. As a whole, the welded part accommodating part 12 has a constricted shape that is narrower than the tip accommodating part 11, the width part accommodating part 13, and the covering part accommodating part 14 located on both sides in the axial direction L. There is.

Further, the cover body 20, which has a symmetrical shape with the cap body 10, has a similar shape, and when looking at the cover body 20 as a whole, the portion that covers the welded portion 210 (uniform portion 21b to be described later) is formed on both sides in the axial direction L. It has a constricted shape that is narrower than the part.

As a result, when a force in the axial direction L is applied to the exposed conductor 200 housed in the cap body 10, the wide tip part 220, the width part 230, and the accommodated part 301 are moved to the narrow weld part accommodation part. 12 and the uniform portion 21b can function as a retainer.

Furthermore, as shown in FIGS. 3(a) to 3(c), the cap body 10 has a portion of the tip accommodating portion 11 corresponding to the tapered portion 221 on the tip side so as to follow the shape of the exposed conductor 200. It is composed of a tapered portion 11a that becomes wider toward the end. Furthermore, the welded portion accommodating portion 12 is configured in a straight shape with a uniform width, and the width portion accommodated portion 13 is configured in a tapered shape that gradually becomes narrower toward the welded portion accommodated portion 12. Further, the tapered portion 11a, the welded portion accommodating portion 12, and the width portion accommodating portion 13 are each formed with a width along the tapered portion 221, the welded portion 210, and the width portion 230. Since the welded portion accommodating portion 12 is formed with a width along the welded portion 210, it is narrower than the tip portion 220.

Further, the tip cover body 21 is also shaped symmetrically with the tip accommodating portion 11, the welding portion accommodating portion 12, and the width portion accommodating portion 13. For this reason, it has a tip side taper part 21a, a uniform part 21b, and a rear end side taper part 21c having the same shape as the tapered part 11a, the welded part accommodating part 12, and the width part accommodating part 13, and the tapered part 221, respectively. , and is formed with a width along the welded part 210 and the width part 230. Since the uniform portion 21b is formed with a width along the welded portion 210, it is narrower than the tip portion 220.

The covering part accommodating part 14 is connected to the widest part of the width part accommodating part 13 and is wider than the welding part accommodating part 12, and the covering part cover body 22 having a symmetrical shape is also connected to the uniform part 21b. It is wider than that.

Each part of the cap body 10 and the cover body 20 is formed with such a shape and width, and the cap body 10 and the cover body 20 have a constricted shape corresponding to the shape and width of the exposed conductor 200. With this configuration, when the terminal cap 1 is attached to the terminal 110, the exposed conductor 200 fits into the cap body 10 and the cover body 20, and the terminal 110 is accommodated with a small play with respect to the terminal cap 1. be done. Further, the tip portion 220 can reliably function as a retainer for the welded portion accommodating portion 12 and the uniform portion 21b, which correspond to the constricted portions of the cap body 10 and the cover body 20.

Further, as shown in FIG. 3(c), the distal end cover body 21 is provided with a restricted portion 30 that extends toward the sheathing portion cover body 22 and whose movement is regulated by the sheathing portion cover body 22. . Specifically, the regulated portion 30 is provided at a predetermined position of the rear end tapered portion 21c, which is a portion on the rear end side of the tip cover body 21 in the axial direction L.

When the tip cover body 21 closes the openings of the tip accommodating portion 11, welding portion accommodating portion 12, and width portion accommodating portion 13, and the opening of the sheathing portion accommodating portion 14 is blocked by the sheathing portion cover body 22, the regulated A part of the distal end side of the covering part cover body 22 is made to overlap with the upper side of the part 30. Then, since the sheathing part cover body 22 overlaps the regulated part 30 from above, the pivoting of the distal end cover body 21 is inhibited, and the movement is regulated by the sheathing part cover body 22 .

Further, the terminal cap 1 is provided with an engaging portion 40 as a fixing portion for fixing the tip cover body 21 that closes the openings of the tip accommodating portion 11, the welded portion accommodating portion 12, and the width portion accommodating portion 13 to the cap body 10. ing. The engaging portion 40 is provided in the uniform portion 21b and is engaged with the engaged portion 41 provided in the welded portion accommodating portion 12 to fix the tip cover body 21 to the cap body 10.

Further, the terminal cap 1 is provided with an engaging portion 50 as a covering portion fixing portion for fixing the covering portion cover body 22 that closes the opening of the covering portion accommodating portion 14 to the covering portion accommodating portion 14 . The engaging part 50 is provided on the sheathing part cover body 22 and is engaged with the engaged part 51 provided on the sheathing part accommodating part 14 to fix the sheathing part cover body 22 to the sheathing part accommodating part 14. .

Then, by fixing the sheathing part cover body 22 to the sheathing part accommodating part 14 by the engaging part 50, movement of the tip cover body 21 is regulated via the restricted part 30, and thereby, the tip cover body 21 is The openings of the tip accommodating part 11, the welding part accommodating part 12, and the width part accommodating part 13 are fixed in a closed state. That is, the engaging portion 50 functions as one of the fixing portions that fix the tip cover body 21 to the cap body 10 via the regulated portion 30.

As described above, in the terminal cap 1, the engaging portion 40 serves as a fixing portion for fixing the tip cover body 21 that closes the openings of the tip accommodating portion 11, the welding portion accommodating portion 12, and the width portion accommodating portion 13 to the cap body 10. A plurality of fixing parts with the engaging part 50 are provided.

Further, in the engaging portion 40, the tip cover body 21 is pivoted about the width direction W1 and is engaged with the engaged portion 41, thereby fixing the tip cover body 21 to the cap body 10. On the other hand, in the engaging part 50, the sheathing part cover body 22 is pivoted about the vertical width direction W2 and is locked to the engaged part 51, and the distal end cover body 21 is moved via the restricted part 30. The distal end cover body 21 is fixed to the cap body 10 by regulating. In this way, the manner in which the engaging portion 50 is fixed is configured to be different from the manner in which the engaging portion 40 is fixed.

Next, the process of attaching the terminal cap 1 configured as described above to the terminal 110 will be briefly explained based on FIG. 4. Here, FIG. 4 shows an explanatory diagram showing the process of attaching the terminal cap 1 to the terminal 110.

First, as shown in FIG. 4A, the tip portion of the terminal 110 of the covered electric wire 100 is placed in the tip accommodating portion 11, the welded portion accommodating portion 12, the width portion accommodating portion 13, and the sheathing portion accommodating portion 14 of the cap body 10. 220, the welded part 210, the width part 230, and the accommodated part 301 are respectively arranged. Then, the tip cover body 21 is pivoted about the width direction W1 by the hinge to close the openings of the tip accommodating portion 11, the welding portion accommodating portion 12, and the width portion accommodating portion 13, and the distal end cover body 21 is moved by the engaging portion 40. is fixed to the cap body 10.

Subsequently, as shown in FIG. 4(b), the covering part cover body 22 is pivoted around the axial direction L by the hinge to close the opening of the covering part accommodating part 14, and the covering part cover body 22 is housed in the covering part. The tip cover body 21 is also fixed to the cap body 10 by the engaging part 50. Thereby, as shown in FIG. 4(c), the terminal cap 1 is attached with the terminal 110 covered.

According to the terminal cap 1 configured in this way, the terminal cap 1 can be easily attached, and short circuits can be reliably prevented.

Specifically, since the welding part accommodating part 12 is narrower than the tip accommodating part 11, the wide tip part 220 of the exposed conductor 200 can function as a retainer for the narrow welding part accommodating part 12. . Thereby, movement of the terminal cap 1 in the axial direction L can be restricted. Furthermore, since the engaging portion 40 and the engaging portion 50 that function as fixing portions for fixing the tip cover body 21 to the cap body 10 are provided, it is thereby possible to effectively prevent the tip cover body 21 from coming off. .

Further, movement of the terminal cap 1 in the axial direction L can be restricted by simply housing the exposed conductor 200 in the cap body 10, and the engaging portion 40 and the engaging portion 50, which function as fixing portions, are provided on the terminal cap 1. Therefore, there is no need to use a separate material such as tape. Therefore, the installation work can be facilitated.

In this way, the terminal cap 1 restricts the movement of the terminal cap 1 in the axial direction L and prevents the distal end cover body 21 from coming off. Installation work can be made easier. Therefore, according to the present invention, the terminal cap 1 can be easily attached, and short circuits can be reliably prevented.

Furthermore, a plurality of fixing parts such as an engaging part 40 and an engaging part 50 are provided as fixing parts for fixing the tip cover body 21 to the cap main body 10. Therefore, even if some force acts on the terminal cap 1 and one of the fixing states is released, the distal end cover body 21 can be prevented from coming off by the other fixing parts.

Furthermore, since the engagement portions 40 and 50 that function as fixation portions are fixed in different ways, after some force is applied to the terminal cap 1 and one of them is released from the fixed state, Even if the same type of force acts on it, the fixed state will not be released. In other words, unless a plurality of types of forces are applied, the state in which both the engaging portion 40 and the engaging portion 50 are fixed is not released.

Then, the movement of the tip cover body 21 is regulated by the sheathing part cover body 22 via the regulated part 30 . Therefore, in order to remove the terminal cap 1 from the insulated wire 100, a stepwise operation is required, for example, to release the fixed state of the engaging part 50 and then release the fixed state of the engaging part 40 on the tip cover body 21. It becomes necessary.

Further, the tip cover body 21 is configured to be pivotable by a hinge along the width direction W1, and the covering portion cover body 22 is configured to be pivotable by a hinge along the axial direction L. Therefore, the direction of rotation for opening and closing the tip cover body 21 and the direction of rotation for opening and closing the covering portion cover body 22 are orthogonal to each other.

Therefore, in order to open the tip cover body 21, at least after a rotational force for opening and closing the covering part cover body 22 is applied, a rotational force perpendicular to this must be applied. . In other words, forces must be applied stepwise and in greatly different directions, which can complicate the force that needs to be applied to open the tip cover body 21. Thereby, it is possible to more reliably prevent the terminal cap 1 from accidentally falling off.

Further, at the end 110 of the covered wire 100, a width portion 230 is formed between the welded portion 210 of the exposed conductor 200 and the accommodated portion 301. On the other hand, the tip cover body 21 is provided with a rear end tapered portion 21c, thereby providing a portion that covers the width portion 230 on the side of the covering portion cover body 22 in the tip cover body 21. . Thereby, the edge portion 230 can be covered by the tip cover body 21, and even when the covered wire 100 is attached to the covered wire 100 having the edge portion 230, short circuits can be reliably prevented.

In addition, in the terminal 110, the exposed conductors 200 of the plurality of covered wires 100 are combined into one, and one terminal cap 1 is attached to this terminal 110, so when attaching the terminal cap 1 to each coated wire 100, In comparison, the work of attaching the terminal cap 1 can be made easier.

This invention is not limited to the configuration of the above-described embodiments, and can be implemented in many other embodiments.

For example, in the above description, the tip cover body 21 is arranged at the tip of the tip accommodating portion 11 in the axial direction L, and is configured to be pivotable by a hinge along the width direction W1 perpendicular to the axial direction L. ing. However, the present invention is not necessarily limited to this, and for example, the tip cover body 21 is arranged in the width direction W1 orthogonal to the axial direction L of the tip accommodating portion 11, the welding portion accommodating portion 12, and the width portion accommodating portion 13, and It may be configured to be pivotable by a hinge along the axial direction L. In this case, as shown in FIG. 5, the tip cover body 21 and the covering part cover body 22 may be arranged on opposite sides of the cap body 10 in the width direction W1.

With this configuration, the terminal cap 1 can be attached to the covered electric wire 100 by a simple operation of pivoting the tip cover body 21 and the covering part cover body 22 by the hinges along the axial direction L, respectively. I can do it.

Further, when the tip cover body 21 and the covering part cover body 22 are arranged on opposite sides of the cap body 10 in the width direction W1, the rotation direction for opening and closing the tip cover body 21 and the covering part cover The direction of rotation for opening and closing the body 22 can be reversed. Therefore, in order to open the tip cover body 21, at least after a rotational force for opening and closing the covering part cover body 22 is applied, a rotational force in the opposite direction must be applied. No. In other words, forces must be applied stepwise and in greatly different directions, which can complicate the force that needs to be applied to open the tip cover body 21. Therefore, it is possible to more reliably prevent the terminal cap 1 from accidentally falling off.

Further, for example, a widening body may be provided in the tip accommodating portion 11 to widen the width of the tip portion 220. The widening body is not particularly limited as long as it can widen the width of the tip portion 220, but for example, as shown in FIGS. It may also be a widened body 60.

Specifically, as shown in FIGS. 6 and 7, the widening body 60 is formed in the shape of a triangular prism with a pointed tip facing toward the welding part accommodating part 12, and is provided in the tapered part 11a of the tip accommodating part 11. , the protrusion height is such that it extends to the bottom surface of the distal end cover body 21 when the distal end cover body 21 is closed. At this time, a recess for receiving the tip of the widening body 60 may be provided at a corresponding location of the tip cover body 21.

When the distal end portion 220 is accommodated in the distal end accommodating portion 11 provided with such a widening body 60, if there is surplus space in the tapered portion 11a, the distal end of the distal end portion 220 widens by the width of the widening body 60. That will happen. Further, if there is no surplus space in the tapered portion 11a, the tip portion 220 will be pressed against the wall surface of the tapered portion 11a.

In this way, the widening body 60 allows the distal end portion 220 to be made wider, and the function of retaining the welded portion accommodating portion 12 from falling out can be improved. This restricts the movement of the terminal cap 1 in the axial direction L, and can more reliably prevent the terminal cap 1 from falling off carelessly.

In the above description, the engaging part 40 and the engaging part 50 are provided as fixing parts for fixing the tip cover body 21 to the cap main body 10. However, the method of fixing the fixing part is not limited to this, and the fixing mode of the fixing part is not limited to the engaging part 40 or the engaging part 50, but various fixing methods can be used as long as the tip cover body 21 can be fixed to the cap body 10. Aspects can be used. Moreover, the position where the fixing part is provided may be selected as appropriate, and even when a plurality of fixing parts are provided, the respective fixing parts may be provided at different positions or may be provided at the same position.

For example, the regulated portion 30 may not be provided, the engaging portion 50 may not function as a fixing portion for fixing the tip cover body 21 to the cap body 10, and another fixing portion may be provided. Further, the engaging portion 40 may be provided in other parts such as the tip tapered portion 21a or the rear tapered portion 21c instead of the uniform portion 21b, or a fixing method different from locking may be used.

To give a more specific example, the tip cover body 21 is provided as a fixing portion for fixing the tip cover body 21 to the cap body 10. Further, a first fixing portion that is locked and fixed to at least one of the tip accommodating portion 11 and the welded portion accommodating portion 12, and a first fixing portion provided in at least one of the tip accommodating portion 11 and the welded portion accommodating portion 12, and a tip cover body A second fixing portion may be provided that is latched and fixed to 21.

For example, as shown in FIG. 8, a first fixing part 70 is provided on the tip cover body 21 and is locked and fixed to the welding part accommodating part 12; A second fixing part 80 that is locked and fixed to the second fixing part 80 may be provided. More specifically, the first fixing part 70 is configured to be locked to a locked part 71 provided at a corresponding location of the welded part accommodating part 12, and the second fixing part 80 is configured to lock to a locked part 71 provided at a corresponding location of the welded part accommodating part 12. It is configured to be inserted into a locking hole 81 provided at a corresponding location and to be locked in the locking hole 81.

With this configuration, in order to remove the tip cover body 21, both the first fixing part 70 and the second fixing part 80, which are provided on opposite sides and lock in opposite directions, must be in the locked state. A complicated operation is required to release it. Thereby, it is possible to more reliably prevent the terminal cap 1 from accidentally falling off while using a fixing method of locking that does not require complicated work.

As another specific example, for example, a first fixing part and a second fixing part are provided as fixing parts for fixing the tip cover body 21 to the cap main body 10, and each has a structure that locks and fixes the tip cover body 21 to a part of the other party. The first fixing part and the second fixing part may have different locking directions.

For example, as shown in FIG. 9, a first fixing portion 70a is provided on the inside in the width direction W1 at a predetermined location of the tip cover body 21, and a second fixing portion 80a is provided on the outside in the width direction W1 at the same location. The first fixing part 70a is configured to be locked and fixed to a locked part 71a provided inside W1 at a corresponding location of the welding part accommodating part 12, and the second fixing part 80a is fixed by welding. It may be configured to be locked and fixed to a locked portion 81a provided on the outside of W1 at a corresponding location in the portion housing portion 12. As a result, the first fixing part 70a and the second fixing part 80a have a structure in which they are locked and fixed to the locked part 71a and the locked part 81a, which are part of the other party, respectively, and the locking direction is fixed. I am against it.

With this configuration, in order to remove the tip cover body 21, a complicated operation is required to release the locking state of both the first fixing part 70a and the second fixing part 80a, which have different locking directions. It becomes necessary. Thereby, it is possible to more reliably prevent the terminal cap 1 from accidentally falling off while using a fixing method of locking that does not require complicated work.

Furthermore, in the above description, the engaging portion 40 and the engaging portion 50 are provided as the fixing portions for fixing the tip cover body 21 to the cap body 10, and a plurality of fixing portions with different fixing modes are provided. However, this is not necessarily the case. Not limited to. For example, the number of fixing parts that fix the tip cover body 21 to the cap main body 10 is not limited to two, but may be three or more, or may be only one. Further, when a plurality of fixing parts are provided, the same fixing mode may be used for each fixing part.

The specific shapes of the cap body 10 and the cover body 20 shown in the above description are merely examples, and may be changed as appropriate. For example, in the cap body 10, the welding part accommodating part 12 may be narrower than the tip accommodating part 11, and the width part accommodating parts 13 and 14 may be wider than the welding part accommodating part 12. Therefore, each part does not necessarily have to have a width and shape that follows the tapered part 221, welded part 210, and width part 230, and may have a shape different from the shape shown in the above description. Further, the cap body 10 may accommodate the tip portion 220, the welded portion 210, and the accommodated portion 301 in its entirety, and the cover body 20 may be a plate-shaped member that closes the opening of the cap body 10.

However, the invention is not necessarily limited to this, and the terminal cap 1 may be attached to the covered wire 100 in which the exposed conductor 200 does not have the width portion 230 formed therein. Further, in that case, the terminal cap 1 may have a configuration in which it does not have the width portion accommodating portion 13 or the rear end side tapered portion 21c.

In the above description, a configuration has been described in which the regulated portion 30 extending toward the covering portion cover body 22 is provided at a predetermined position of the rear end side tapered portion 21c of the distal end cover body 21. However, the configuration of the regulated portion 30 is not necessarily limited to this, and may have various configurations as long as its movement is regulated by the covering portion cover body 22 that closes the opening of the covering portion accommodating portion 14. For example, the covering part cover body 22 is provided over the width part 230 so that a part of the covering part cover body 22 overlaps the rear end tapered part 21c, and the rear end tapered part 21c functions as the regulated part 30. Good too.

In the above description, the distal end cover body 21 and the covering portion cover body 22 are configured as separate bodies, but the present invention is not necessarily limited to this, and the distal end cover body 21 and the covering portion cover body 22 may be integrally configured. .
