Description

The present invention relates to a terminal.

Conventionally, a technology is known in which a terminal crimped onto the end of an electric wire is accommodated in a terminal accommodating chamber formed in a housing.

Patent document 1 discloses a configuration in which a lance that can be elastically displaced in a direction that intersects with the terminal insertion direction is formed in the terminal receiving chamber.

When a terminal is inserted into the terminal accommodating chamber, the lance interferes with the terminal and is elastically displaced as the terminal is inserted. When the terminal is inserted into the terminal accommodating chamber to the accommodating position where it is electrically connected to the mating terminal, the lance elastically returns to its original position and engages with the terminal. This allows the terminal to be accommodated in the terminal accommodating chamber.

JP 2014-82015 A

When multiple terminal accommodating chambers are formed in a housing, a new terminal may be inserted into the target terminal accommodating chamber while terminals are accommodated in the surrounding terminal accommodating chambers.

In this case, the worker must perform the insertion work within a narrow field of vision while pushing aside the wires surrounding the terminal receiving chamber to be inserted.

For this reason, when a worker grasps the part of the terminal that is crimped to the electric wire and pushes the terminal into the terminal receiving chamber to be inserted, the insertion work is performed in a narrow field of vision, making it difficult to insert the terminal horizontally and prone to the terminal being inserted at an angle. If the wire is buckled or the terminal is only partially inserted due to the oblique insertion of the terminal, it may be necessary to redo the insertion work, which may cause problems with the insertion work.

The present invention was made in consideration of the problems inherent in the conventional technology. The object of the present invention is to provide a terminal that can be easily inserted while preventing the terminal from being inserted at an angle, even when a new terminal is inserted into a target terminal accommodating chamber in a housing having multiple terminal accommodating chambers and terminals are already accommodated in the surrounding terminal accommodating chambers.

The terminal according to the present invention includes a terminal portion having a base portion extending along the axial direction and having an electric wire placement surface on which an electric wire is placed, a core wire crimping portion formed in a first portion of the base portion and crimped to a core wire exposed from the insulating coating of the electric wire, and a coating crimping portion formed in a second portion of the base portion and crimped to the insulating coating, a flat connecting portion extending along the axial direction from an end of the base portion on the second portion side, and a cylindrical holding portion extending along the axial direction from the connecting portion, and when an external force is applied to the holding portion in a direction intersecting the axial direction, the connecting portion breaks.

The present invention provides a terminal that can be easily inserted without inserting the terminal obliquely, even when a new terminal is inserted into a target terminal chamber in a housing that has multiple terminal chambers and terminals are already inserted in the surrounding terminal chambers.

[Terminal configuration]
First, the configuration of the terminal 1 will be described with reference to Figures 1 to 4. Figure 1 is a perspective view of the terminal 1 as viewed from the rear of the terminal 1. Figure 2 is a perspective view of the terminal 1 as viewed from the front of the terminal 1. Figure 3 is a plan view of the terminal 1. Figure 4 is a cross-sectional view taken along line IV-IV in Figure 3.

The X direction shown in Figures 1 to 4 corresponds to the axial direction AD of terminal 1 (see Figure 3). The Y direction shown in Figures 1 to 4 corresponds to the width direction of terminal 1 and is perpendicular to the X direction. The Z direction shown in Figures 1 to 4 corresponds to the height direction of terminal 1 and is perpendicular to the X and Y directions.

The +X side and -X side shown in Figs. 1 to 4 correspond to the front and rear of terminal 1, respectively. The +Y side and -Y side shown in Figs. 1 to 4 correspond to the right and left of terminal 1, respectively, when facing the front of terminal 1. The +Z side and -Z side shown in Figs. 1 to 4 correspond to the top and bottom of terminal 1, respectively.

The terminal 1 is formed by pressing a metal plate. As shown in Figs. 1 and 2, the terminal 1 includes a terminal portion 10, a connecting portion 30, and a holding portion 50. The terminal 1 is crimped to an electric wire at the terminal portion 10. The terminal 1 is held by a worker at the holding portion 50. The connecting portion 30 connects the terminal portion 10 and the holding portion 50. In this embodiment, the terminal 1 may be held by a work machine such as a robot arm at the holding portion 50.

[Terminal configuration]
The terminal portion 10 has a base portion 11, a core wire crimping portion 13, a coating crimping portion 15, and a connection portion 17. As shown in Fig. 3, the base portion 11 has an electric wire placing surface 11a, a tapered surface 11b, and a contact surface 11c along the axial direction AD (X direction) of the terminal 1. The electric wire placing surface 11a is a surface on which the electric wire is placed when the terminal 1 is crimped to the electric wire, and is located on the -X side of the base portion 11.

Tapered surface 11b connects to wire placement surface 11a on the -X side and to abutment surface 11c on the +X side. The width (length in the Y direction) of tapered surface 11b increases from wire placement surface 11a toward abutment surface 11c. Abutment surface 11c is the surface where terminal 1 abuts against the mating terminal when terminal 1 is inserted into the terminal accommodating chamber of the housing, and is located on the +X side of base 11. Abutment surface 11c has an abutment portion 12 in the center. On abutment surface 11c, abutment portion 12 is raised in the height direction (Z direction) of terminal 1.

The base portion 11 has a first portion P1, a second portion P2, and a third portion P3. The first portion P1 and the second portion P2 are located on the +X side and the -X side, respectively, of the electric wire mounting surface 11a. The third portion P3 is located on the abutment surface 11c.

A core wire crimping portion 13 is formed in the first portion P1 of the base portion 11. In this embodiment, the core wire crimping portion 13 has a pair of core wire crimping pieces 13a, 13a. The core wire crimping pieces 13a, 13a extend upward (to the +Z side) from both sides (the +Y side end and the -Y side end) of the first portion P1 of the base portion 11. When the terminal 1 is crimped to the electric wire, the core wire crimping pieces 13a, 13a are crimped to the core wire exposed from the insulating coating of the electric wire. In this way, the core wire crimping portion 13 is crimped to the core wire of the electric wire. In this way, by crimping the core wire crimping pieces 13a, 13b, the cross section perpendicular to the axial direction AD at the first portion P1 of the base portion 11 is configured to have a substantially closed cross-sectional shape. The configuration for crimping the core wire crimping portion 13 to the core wire of the electric wire is not limited to the core wire crimping pieces 13a, 13a, and other configurations may be used.

The second portion P2 of the base portion 11 is formed with a coating crimping portion 15. In this embodiment, the coating crimping portion 15 has a pair of coating crimping pieces 15a, 15a. The coating crimping pieces 15a, 15a extend upward (to the +Z side) from both sides (the +Y side end and the -Y side end) of the second portion P2 of the base portion 11. When the terminal 1 is crimped to the electric wire, the coating crimping pieces 15a, 15a are crimped to the insulating coating of the electric wire. As a result, the coating crimping portion 15 is crimped to the insulating coating of the electric wire. In this way, by crimping the coating crimping pieces 15a, 15b, the cross section perpendicular to the axial direction AD at the second portion P2 of the base portion 11 is configured to have a substantially closed cross-sectional shape. Note that the configuration for crimping the coating crimping portion 15 to the insulating coating of the electric wire is not limited to the coating crimping pieces 15a, 15a, and other configurations may be used.

A connection portion 17 is formed in the third portion P3 of the base portion 11. In this embodiment, the connection portion 17 has a pair of connection pieces 17a, 17a. The connection pieces 17a, 17a extend upward (to the +Z side) from both sides (the +Y side end and the -Y side end) of the third portion P3 of the base portion 11, and their tips are bent toward the abutment portion 12 side (-Z side) of the abutment surface 11c. When the terminal 1 is inserted into the terminal accommodating chamber of the housing, the mating terminal is sandwiched between the tips of the connection pieces 17a, 17a and the abutment portion 12 of the abutment surface 11c. As a result, the connection portion 17 is electrically connected to the mating terminal. Note that the configuration for electrically connecting the connection portion 17 to the mating terminal is not limited to the connection pieces 17a, 17a, and other configurations may be used.

[Configuration of the connecting part]
4, the connecting portion 30 is formed in a flat plate shape and has an upper surface 31 and a lower surface 33. The upper surface 31 and the lower surface 33 are two surfaces along the axial direction AD of the connecting portion 30 in a cross-sectional view along the axial direction AD of the terminal 1. That is, the upper surface 31 and the lower surface 33 are the +Z side surface and the -Z side surface of the connecting portion 30, respectively.

The top surface 31 is connected to the electric wire mounting surface 11a of the base portion 11 on the +X side of the connecting portion 30, and is connected to the side surface 51 of the holding portion 50 described below on the -X side of the connecting portion 30. Thus, in the terminal 1, the top surface 31 is formed flush with the electric wire mounting surface 11a, the tapered surface 11b, the abutment surface 11c excluding the abutment portion 12, and the side surface 51 of the holding portion 50.

The lower surface 33 is connected to the rear surface of the base portion 11 on the +X side of the connecting portion 30, and is perpendicular to the first opening surface 53 of the holding portion 50 (described later) on the -X side of the connecting portion 30.

As shown in FIG. 3, in a plan view of the terminal 1, the width (length in the Y direction) of the connecting portion 30 is smaller than the width (length in the Y direction) of the second portion P2 of the base portion 11, and is also smaller than the width (length in the Y direction) of the retaining portion 50. In this way, in a plan view of the terminal 1, the shape changes discontinuously between the connecting portion 30 and the second portion P2 of the base portion 11, and the shape changes discontinuously between the connecting portion 30 and the retaining portion 50.

[Configuration of holding part]
3 and 4, the holding portion 50 is formed in a cylindrical shape and has a side surface 51, a first opening surface 53, and a second opening surface 55. The first opening surface 53 is located on the +X side of the holding portion 50 and is perpendicular to the axial direction AD of the terminal 1. The second opening surface 55 is located on the -X side of the holding portion 50 and is perpendicular to the axial direction AD of the terminal 1. In the holding portion 50, the internal space surrounded by the side surface 51 communicates with the outside via the first opening surface 53 and the second opening surface 55.

In the holding portion 50, the cross section of the holding portion 50 perpendicular to the axial direction AD of the terminal 1 is formed so as to become smaller along the axial direction AD toward the connecting portion 30. Therefore, in the cross sections of the holding portion 50 perpendicular to the axial direction AD of the terminal 1, the first opening surface 53 is the smallest cross section, and the second opening surface 55 is the largest cross section. Note that since the holding portion 50 is formed by performing a press process or the like on a metal plate, when the portion of the metal plate formed into the holding portion 50 is bent to the -Z side, both sides of the portion may not be in complete contact with each other, and a narrow gap may exist at the lower end (the end on the -Z side) of the holding portion 50. In this way, the cross section perpendicular to the axial direction AD in the holding portion 50 is configured to have an approximately closed cross-sectional shape.

[Configuration of terminal crimped onto electric wire]
Next, the configuration of the terminal 1 crimped to the electric wire 100 will be described with reference to Fig. 5 to Fig. 7. Fig. 5 is a perspective view of the terminal 1 crimped to the electric wire 100. Fig. 6 is a cross-sectional view along the axial direction of the terminal 1 crimped to the electric wire 100. Fig. 7 is a cross-sectional view along the axial direction of the terminal 1 crimped to the electric wire 100 after the connecting portion 30 is broken.

As shown in Figures 5 and 6, the electric wire 100 has a core wire 101 and an insulating coating 103. The core wire 101 is covered with the insulating coating 103. At the end of the electric wire 100, the core wire 101 is exposed from the insulating coating 103.

When the terminal 1 is crimped to the electric wire 100, the end of the electric wire 100 is placed on the electric wire placement surface 11a of the base portion 11 of the terminal portion 10 from the -X side of the terminal portion 10. Specifically, at the end of the electric wire 100, the core wire 101 exposed from the insulating coating 103 is disposed in an area including the first portion P1 of the base portion 11, and the insulating coating 103 is disposed in an area including the second portion P2 of the base portion 11.

In this state, the core wire crimping portion 13 formed in the first portion P1 of the base portion 11 is crimped to the core wire 101. In this embodiment, the tip portions of the core wire crimping pieces 13a, 13a are bent toward the electric wire mounting surface 11a (-Z side) and crimped to the core wire 101.

Similarly, the coating crimping portion 15 formed on the second portion P2 of the base portion 11 is crimped to the insulating coating 103. In this embodiment, the tip portions of the coating crimping pieces 15a, 15a are bent toward the wire placement surface 11a (-Z side) and crimped to the insulating coating 103.

As a result, the terminal 1 is crimped to the electric wire 100. Note that the insulating coating 103 of the electric wire 100 is in contact with the upper surface 31 of the connecting portion 30 and the side surface 51 of the holding portion 50 on the -X side of the terminal 1.

As shown in FIG. 7, in the terminal 1, the connecting portion 30 is formed in a flat plate shape and is located between the second portion P2 of the base portion 11 and the holding portion 50, which are configured to have a substantially closed cross-sectional shape. When an external force acts in a direction intersecting the axial direction AD of the terminal 1, the second portion P2 of the base portion 11 and the holding portion 50, which are configured to have a substantially closed cross-sectional shape, are less likely to deform than the flat connecting portion 30. Therefore, when an external force is applied to the holding portion 50 in a direction intersecting the axial direction AD of the terminal 1, stress is concentrated in the connecting portion 30, and the connecting portion 30 breaks. In this embodiment, the direction in which the external force is applied is the -Z side of the height direction (Z direction) of the terminal 1. When the connecting portion 30 breaks, the connecting portion 30 is separated into a portion 30a on the second portion P2 side of the base portion 11 and a portion 30b on the holding portion 50 side.

[Terminal insertion work]
Next, the insertion operation of the terminal 1 will be described with reference to Figures 8 and 9. Figure 8 is a diagram illustrating the state before the terminal 1 is inserted into the terminal accommodating chamber 210 into which it is to be inserted. Figure 9 is a diagram illustrating the state after the terminal 1 is inserted into the terminal accommodating chamber 210 into which it is to be inserted. The housing 200 is provided, for example, in an electric connection box such as a relay box, a connector such as a multi-pole connector, and the like. As shown in Figure 8, the housing 200 has a plurality of terminal accommodating chambers 210 formed therein.

In this embodiment, for example, during manufacture or use, the terminal 1 is inserted into the terminal accommodating chamber 210 to be inserted, with the terminal accommodated in the terminal accommodating chambers 210 arranged around the terminal accommodating chamber 210 to be inserted (see FIG. 8). The axial direction AD of the terminal 1 corresponds to the insertion direction of the terminal 1.

The worker pinches the holding portion 50 of the terminal 1 while pushing aside the electric wires present around the terminal accommodating chamber 210 to be inserted, and inserts the terminal 1 from the rear in the insertion direction into the terminal accommodating chamber 210 to be inserted. In the terminal 1, the holding portion 50 is provided rearward of the terminal portion 10 in the insertion direction of the terminal 1. Therefore, even if there are electric wires around the terminal accommodating chamber 210 to be inserted, the worker can insert the terminal 1 horizontally from the rear in the insertion direction of the terminal 1, aiming at the opening of the terminal accommodating chamber 210 to be inserted, into the terminal accommodating chamber 210 to be inserted. Therefore, even when inserting the terminal 1 while pushing aside the electric wires present around the terminal accommodating chamber 210 to be inserted, it is possible to prevent the terminal 1 from being inserted obliquely.

As shown in FIG. 9, the terminal receiving chamber 210 to be inserted is provided with a lance 221 and a mating terminal 223. When the terminal 1 is inserted into the terminal receiving chamber 210 to be inserted, the lance 221 interferes with the terminal 1 and is elastically displaced as the terminal 1 is inserted. In this embodiment, the lance 221 interferes with the connecting pieces 17a, 17a of the terminal portion 10 and is elastically displaced in the opposite direction to the terminal 1 as the terminal 1 is inserted.

When the terminal 1 is inserted to a receiving position where it is electrically connected to the mating terminal 223, the lance 221 elastically returns to its original position and engages with the terminal 1. In this embodiment, when the lance 221 elastically returns to its original position, it engages with the rear ends of the connecting pieces 17a, 17a of the terminal portion 10. In this state, the mating terminal 223 is sandwiched between the tip ends of the connecting pieces 17a, 17a and the abutment portion 12 of the abutment surface 11c. This electrically connects the terminal 1 to the mating terminal 223. When the terminal 1 is inserted to a receiving position of the terminal receiving chamber 210 to be inserted, the connecting portion 30 and the holding portion 50 are located outside the terminal receiving chamber 210 to be inserted.

When the worker inserts the terminal 1 into the terminal receiving chamber 210, the worker applies an external force to the holding portion 50 in a direction intersecting the axial direction AD of the terminal 1, causing the connecting portion 30 to break. This causes the holding portion 50 to be cut off from the connecting portion 30, preventing it from interfering with the electric wires present around the terminal receiving chamber 210.

[Action and Effects]
According to this embodiment, the terminal 1 includes a terminal portion 10, a connecting portion 30, and a holding portion 50. The terminal portion 10 extends along an axial direction AD of the terminal 1, and includes a base portion 11, a core wire crimping portion 13, and a coating crimping portion 15. The base portion 11 has an electric wire placing surface 11a on which the electric wire 100 is placed. The core wire crimping portion 13 is formed in a first portion P1 of the base portion 11, and is crimped to a core wire 101 exposed from an insulating coating 103 of the electric wire 100. The coating crimping portion 15 is formed in a second portion P2 of the base portion 11, and is crimped to the insulating coating 103.

The connecting portion 30 is formed in a flat plate shape and extends from the end of the base portion 11 on the second portion P2 side along the axial direction AD of the terminal 1. The holding portion 50 is formed in a cylindrical shape and extends from the connecting portion 30 along the axial direction AD of the terminal 1. The connecting portion 30 breaks when an external force is applied to the holding portion 50 in a direction intersecting the axial direction AD of the terminal 1.

With the above-mentioned configuration, the cylindrical holding portion 50 is provided at the rear in the insertion direction of the terminal 1. Therefore, the worker can pinch the holding portion 50 and insert the terminal 1 from the rear in the insertion direction of the terminal 1 into the terminal accommodating chamber 210 to be inserted, and can perform the insertion work from a location away from the terminal accommodating chamber 210 to be inserted with a wide field of view. Therefore, even if there is an electric wire around the terminal accommodating chamber 210 to be inserted, it becomes easy to insert the terminal 1 horizontally into the terminal accommodating chamber 210 to be inserted, and it is possible to prevent the terminal 1 from being inserted obliquely, and to prevent the electric wire 100 from buckling, the terminal 1 from being partially inserted, etc.

When inserting a conventional terminal into the terminal receiving chamber 210 from the rear in the terminal insertion direction, the worker must hold the wire and perform the insertion operation. In this case, if the wire is not rigid enough, the insertion resistance of the lance 221 may cause the wire to buckle.

In addition, because the above-mentioned configuration makes the connecting portion 30 flat and the holding portion 50 cylindrical, when an external force acts in a direction intersecting the axial direction AD of the terminal 1, the holding portion 50 is less likely to deform than the connecting portion 30. Therefore, when an external force is applied to the holding portion 50 in a direction intersecting the axial direction AD of the terminal 1, stress is concentrated on the connecting portion 30, causing the connecting portion 30 to break. Therefore, after the terminal 1 is inserted into the terminal accommodating chamber 210 into which it is to be inserted, the holding portion 50 can be easily cut off from the connecting portion 30, and the holding portion 50 can be prevented from interfering with the electric wire present around the terminal accommodating chamber 210 into which it is to be inserted.

In this way, by using the terminal 1, even when a new terminal is inserted into the target terminal accommodating chamber 210 in a housing 200 in which multiple terminal accommodating chambers 210 are formed and terminals are accommodated in the surrounding terminal accommodating chambers 210, the insertion operation can be easily performed while preventing the terminal from being inserted at an angle.

According to this embodiment, in a plan view of the terminal 1, the length of the connecting portion 30 in the width direction perpendicular to the axial direction AD of the terminal 1 is smaller than the length of the second portion P2 of the base portion 11 in the width direction, and is also smaller than the length of the retaining portion 50 in the width direction.

With the above-described configuration, in a plan view of the terminal 1, the shape changes discontinuously between the connecting portion 30 and the second portion P2 of the base portion 11, and the shape changes discontinuously between the connecting portion 30 and the holding portion 50. Therefore, when an external force is applied to the holding portion 50 in a direction intersecting the axial direction AD of the terminal 1, stress is more concentrated on the connecting portion 30, making the connecting portion 30 more likely to break. Therefore, after the terminal 1 is inserted into the terminal accommodating chamber 210 into which it is to be inserted, the holding portion 50 can be more easily severed from the connecting portion 30.

According to this embodiment, in a cross-sectional view along the axial direction AD of the terminal 1, the upper surface 31 along the axial direction AD of the connecting portion 30 is connected to the wire placement surface 11a and the side surface 51 of the holding portion 50.

With the above-described configuration, in the terminal 1, the upper surface 31 of the connecting portion 30 is formed flush with the electric wire mounting surface 11a of the base portion 11 and the side surface 51 of the holding portion 50. Therefore, when the electric wire 100 is placed on the electric wire mounting surface 11a of the base portion 11, it is possible to avoid the connecting portion 30 and the holding portion 50 interfering with the electric wire 100.

According to this embodiment, the cross section of the holding part 50 perpendicular to the axial direction AD becomes smaller along the axial direction AD toward the connecting part 30.

With the above-described configuration, when an operator grasps the holding portion 50 and pushes the terminal 1 into the terminal receiving chamber 210 to be inserted, the pushing force can be concentrated in the insertion direction of the terminal 1, so that the terminal 1 can be easily pushed into the terminal receiving chamber 210 to be inserted.

[Modification]
In the above-described embodiment, the cross-section of the retaining portion 50 perpendicular to the axial direction AD of the terminal 1 is formed so as to become smaller along the axial direction AD toward the connecting portion 30, but this is not limited to this.

Figure 10 is a perspective view of terminal 1a according to this modified example. The X-axis, Y-axis, and Z-axis shown in Figure 10 correspond to the axial direction, width direction, and height direction of terminal 1a, respectively. The +X side and -X side shown in Figure 10 correspond to the front and rear of terminal 1a, respectively. The +Y side and -Y side shown in Figure 10 correspond to the right and left of terminal 1a, respectively, as viewed from the front of terminal 1a. The +Z side and -Z side shown in Figure 10 correspond to the top and bottom of terminal 1a, respectively.

As shown in FIG. 10, the terminal 1a includes a terminal portion 10, a connecting portion 30, and a holding portion 150. The configurations of the terminal portion 10 and the connecting portion 30 have been described in the above embodiment, so a description thereof will be omitted.

The holding portion 150 is formed in a cylindrical shape and has a side surface 151, a first opening surface 153, and a second opening surface 155. The first opening surface 153 is located on the +X side of the holding portion 150 and is perpendicular to the axial direction of the terminal 1a. The second opening surface 155 is located on the -X side of the holding portion 150 and is perpendicular to the axial direction of the terminal 1a. In the holding portion 150, the internal space surrounded by the side surface 151 communicates with the outside via the first opening surface 153 and the second opening surface 155.

In the holding portion 150, the cross section of the holding portion 150 perpendicular to the axial direction of the terminal 1a is constant along the axial direction. Therefore, in the cross section of the holding portion 150 perpendicular to the axial direction of the terminal 1a, the first opening surface 153 and the second opening surface 55 are the same size.

According to this modified example, the cross section perpendicular to the axial direction of the holding portion 150 is constant along the axial direction.

The above-described configuration allows the holding portion 150 to be formed more easily by pressing a metal plate, etc., so that the terminal manufacturing process can be carried out efficiently.

Although the present embodiment has been described above, the present embodiment is not limited to these, and various modifications are possible within the scope of the gist of the present embodiment.
