DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector compression die, and more particularly, to a C-type, an S-type, and a h-type used for distribution lines.
TECHNICAL FIELD The present invention relates to a technique for crimping a branch sleeve type connector having a sectional shape such as a shape and an electric wire.

[0002]

2. Description of the Related Art Various types of connectors have been proposed for connectors used in distribution lines. Generally, these connectors are caulked to the wires by being compressed by a compression tool with the wires to be connected arranged inside, and function to maintain a semi-permanent connection between the wires.

[0003] As an example of this kind of connector,
There is a shape shown in FIG. This connector 1 is a sleeve-shaped connector 1 for branching a main wire A by crimping another electric wire B (for example, a branch wire) to one electric wire A (for example, a main wire), It has a cross-sectional shape in which a hole 2 for inserting the branch line B and a groove 3 for inserting the main line A are formed.

On the other hand, a compression tool 4 for compressing the connector
Has an approximately U-shaped arm portion 5 that opens in one direction, for example, as shown in FIG. At one end of the arm 5, a cylinder 6 that can advance and retreat the rod 6 a toward the inside of the arm 5 is fixed. A pair of dies 7, 8 facing each other are detachably attached to the inside of the tip of the arm 5 and the tip of the rod 6a of the cylinder 6.

[0005] These dies 7, 8 are both formed in the same shape, and have substantially U-shaped compression portions 7a, 8a which are arranged on the common axis O to face each other.
The support portions 7b, 8b formed integrally with the compression portions 7a, 8a so as to surround the outside of the a, 8a, and the mounting portions 7c, 8c for mounting to the arm portion 5 and the rod 6a of the cylinder 6. Have.

The supporting portions 7b and 8b are formed in a substantially rectangular parallelepiped block shape. Further, the mounting portions 7c, 8
c is, for example, the arm portion 5 and the rod 6 of the cylinder 6.
The peripheral grooves 7d and 8d are formed in a columnar shape so that they can be gripped by a ball chuck mechanism or the like provided in a.

The arm 5 is provided with the cylinder 6
The outer surface 7e of the support portion 7b of the die 7 on one side, which is arranged in parallel with the axis O of the rod 6a and which is attached to the inside of the tip of the arm portion 5, is arranged in contact with the rod 6a of the cylinder 6. It has a contact surface 9 for sliding the outer surface 8e of the support portion 8b of the other die 8 attached to the tip.

In order to branch the electric wire A using such a connector 1, first, a branch line B is inserted into the hole 2 of the connector 1.
Then, the connector 1 to which the branch line B is temporarily attached is moved while being lightly sandwiched between the dies 7 and 8 of the compression tool 4. As shown in FIG. 11, the main line A is inserted into the groove 3 formed in the connector 1 from the gap 10 between the dies 7 and 8.
Is inserted, and finally the compression tool 4 is operated to radially compress the connector 1 together with the two electric wires A and B. Thereby, the branch line B is connected to the main line A, and the electric wire A is branched.

[0009]

However, since such branching work is often carried out on an elevated line, the worker must carry out the branching work at a high place, and a fall accident always occurs. It was dangerous. When the connection operation of the distribution line A is performed in a state where power is supplied (hot state), the indirect method, that is, the compression tool 4 is attached to the tip of a long insulating rod (not shown). Compression work had to be performed in the attached state, and workability was poor.

In recent years, manipulators for power distribution work have been developed in order to prevent such inconveniences and ensure the safety of workers. In the case of using the power distribution manipulator, only the manipulator goes to a high place for the power distribution work, and the worker can perform the branching operation by remotely operating the manipulator on the ground.

The branching operation by the manipulator is performed, for example, as follows. First, on a ground or the like, a branch line B to be connected, for example, a connector B temporarily attached to a wire B of a switch is connected to a high place to be connected, for example,
Lift up on the telephone pole and fix it. In this state, the connector 1 is hanging from the switch. Next, the hanging connector 1 is gripped by one hand of the manipulator, the compression tool 4 attached to the other hand is brought close to the connector 1, and the connector 1 is moved between the dies 7 and 8 of the compression tool 4. Insert

Thereafter, the connector 1 is gripped by applying a preload to the compression tool 4 and the gripped hand is released, thereby changing the connector 1 from the hand to the compression tool 4 and operating the manipulator to operate the connector 1. Groove 2
, The branch tool is completed by operating the compression tool 4 to compress the connector 1 together with the two electric wires A and B.

However, such remote control of the manipulator is performed by the operator while confirming the image transmitted from the camera mounted on the manipulator on the CRT. In comparison, the handling and insertion work of the connector 1 and the electric wires A and B were inflexible, and it was difficult to properly set the connector 1 and the electric wires A and B on the compression tool 4.

As a result, for example, as shown in FIG. 12, when the connector 1 is rotated and set with respect to the dies 7, 8 of the compression tool 4, even if the compression tool 4 is operated. Since the connector 1 is not properly compressed, the crimping between the wires A and B and the connector 1 becomes incomplete, and a problem such as poor contact occurs. Also, connector 1
If the compression tool 4 is operated while rotating the connector 1 and the connector 1 is improperly compressed, the connector 1 must be replaced with a new one. In the end, there was a problem that humans had to work at high places.

The present invention has been made in view of the above-mentioned circumstances, and has been made in consideration of the above circumstances, and is a connector for compressing a connector which can perform a connection operation of a distribution line for crimping a connector 1 to electric wires A and B properly and with a small amount of labor. It is intended to provide dice.

[0016]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is directed to a method in which a connector into which an electric wire is inserted is brought close to each other from the outside in a radial direction opposite to each other, and the electric wire and the connector are simultaneously placed. What is claimed is: 1. A connector compression die comprising a pair of dies which are compressed and connected in a fixed state, wherein each of the dies has a substantially U-shaped compression surface opposed to each other on a common axis, and one of said dies. A guide member disposed on at least one side in the width direction of the dies so as to bridge the side surfaces of both dies, and fitting the outer surface of the connector before compression to the guide members, and There has been proposed a connector compression die provided with a guide hole for inserting the connector into the guide hole while restricting the rotation of the connector, and guide means for guiding the insertion of the connector into the guide hole.

In the above-described connector compression die, the guide means may be formed on a peripheral edge of the guide hole, and may include a first guide surface which gradually narrows toward the die along an insertion direction of the connector. It is effective.

Further, the guide member may be provided on both sides in the width direction of the support portion. In this case, the guide member may be provided on a peripheral edge of the guide hole of the guide hole on a die side in a connector insertion direction. A second guide surface may be provided that gradually widens along the die toward the die. Furthermore, the guide member may be provided with an abutment surface for abutting the guide member in a direction in which both dies approach the dice for fixing the guide member.

Further, the guide member may be attached to one of the dies to which the guide member is attached so as to be relatively movable in a direction in which the two dies come into contact with and separate from each other. It is effective if moving means is provided for moving the guide member so that the guide hole is aligned with the compression surface when the connector is separated to receive the connector between the compression surfaces. Further, in this case, the moving means may be constituted by an urging means disposed between the guide member and one of the dies to which the guide member is attached, and urging the guide member toward the other die. .

Each of the dies has a substantially U-shaped compression surface opposed to the common axis, and has a guide surface gradually expanding outward in the width direction on at least one side in the width direction. A guide which is arranged so as to span one side of the dies on both sides of the dies, and which is fitted with an outer surface of the connector before compression together with the guide surface to penetrate the connector while restraining rotation about its longitudinal axis. The attachment member forming the hole may be fixed.

[0021]

According to the connector compression die of the present invention,
When the connector is inserted between the dies, the connector is inserted through a guide hole of a guide member provided on a lateral side of the die. The guide hole is inserted into the connector by fitting the outer surface of the connector before compression, while restricting the rotation of the connector around the longitudinal axis, so that the connector can be oriented substantially and uniquely with respect to the die.

That is, since the guide member is fixed to one of the dies, the connector guided by the guide means and inserted into the guide hole is inserted between the dies while being properly positioned with respect to the dies. Will be inserted. In this state, by driving the dies closer to each other, the connector is properly compressed together with the electric wires.

In the connector compression die, the guide means may be formed on a peripheral edge of the guide hole, and may be formed of a first guide surface which gradually narrows toward the die along the insertion direction of the connector. Even if the connector is sometimes slightly displaced with respect to the guide hole, as the connector is inserted, the connector is gradually guided on the guide surface so as to be inserted into the guide hole.

Furthermore, if the guide members are provided on both sides in the width direction of the support portion, the connector can be inserted from both sides in the width direction of the die. The connector can be properly inserted.

[0025] In this case, if a second guide surface that gradually expands toward the die along the insertion direction of the connector is provided around the die side of the guide hole of the guide member,
When the connector inserted between the dies from one guide member side penetrates the die and is inserted into the guide hole of the other guide member, the connector is smoothly inserted into the guide hole by the second guide surface. Will be guided to.

Furthermore, if the guide member is provided with an abutment surface for bringing the guide member into contact with the die for fixing the guide member in the approach direction of the two dies, when the two dies are brought close to each other to compress the connector. Even when the guide member is pressed in the die moving direction by the burr generated in the connector or the connector, excessive force acts on the fastening portion between the guide member and the die by contacting the contact surface with the die. Can be prevented. As a result, for example, the soundness of the fastener fixing the guide member and the die is maintained.

Further, if the guide member is mounted on one of the dies so as to be relatively movable in the direction in which the two dies come into contact with and separate from each other, even if the guide member is pressed by the connector when the connector is compressed by the dies, the guide member can be dies. , The pressing force is released, and it is possible to prevent an excessive force from acting on the guide member.

In this case, by providing a moving means for moving the guide member so that the guide hole coincides with the compression surface when the die is separated to receive the connector between the compression surfaces. Only by separating the dies, the operation of the moving means makes it possible to arrange the guide member at an appropriate position for inserting the connector between the compression surfaces.

Further, in this case, if the moving means is constituted by an urging means which is arranged between the guide member and one of the dies to which the guide member is attached and urges the guide member toward the other die, the compression means can be compressed. When the two dies are brought close to each other at this time, the guide member is moved against the urging force of the urging means by the pressing force applied to the guide member via the connector. The guide member is moved by the urging force of the means so that the guide hole coincides with the compression surface.

Each of the dies is provided with a U-shaped compression surface and a guide surface which gradually widens outward in the width direction, and one of the dies is compressed together with the guide surface so as to bridge over the side surfaces of both dies. The same operation as described above can be achieved if the outer surface of the previous connector is fitted to fix the attached member constituting the guide hole to be inserted while restricting rotation about the longitudinal axis.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a connector compression die according to the present invention will be described below with reference to FIG. In describing the connector compression die 20 according to the present invention, the same reference numerals will be used to denote the same parts as those of the conventional connector compression dice shown in FIGS. 10 to 12 to simplify the description. I do.

The connector compression die 2 according to the present embodiment
Numeral 0 is composed of a fixed die 21 and a movable die 22 as shown in FIG. Fixed die 21
Is attached to the inside of the distal end of the compression tool 4 (see FIG. 3), and is formed integrally with a compression portion 21b having a substantially U-shaped compression surface 21a so as to reinforce the compression portion 21b. It has a block-shaped support portion 21c and a mounting portion 21d for mounting to the compression tool 4. A guide member 23 made of a substantially C-shaped flat plate is fixed to both sides in the width direction of the support portion 21c by screws 24.

On the other hand, the moving-side die 22 is a die attached to the tip of the rod 6a of the cylinder 6 of the compression tool 4, and has a compression surface 22a substantially opposed to the compression surface 21a of the fixed die 21. Letter-shaped compression part 22b
And a block-shaped support portion 22c integrally formed to reinforce the compression portion 22b, and a rod 6a of the compression tool 4.
And a mounting portion 22d for mounting to the tip.

The guide member 23 has a guide hole 25 penetrating in the thickness direction, an opening 26 formed by cutting a part of the guide hole 25, and the insertion of the connector 1 into the guide hole 25. And a guide surface 27 for guiding. The guide hole 25 is formed to be slightly larger than the profile of the cross section of the connector 1 before compression, and the outer surface of the connector 1 inserted in the longitudinal axis direction is fitted into the guide hole 25 to fit around the longitudinal axis. And the inner surface thereof is formed so as to be substantially flush with the compression portions 21b and 22b of both dies 21 and 22 opened to receive the connector 1. .

The opening 26 of the guide member 23 is
The wire A is formed so as to match the groove 3 of the connector 1 inserted into the guide hole 25 and has a width larger than the outer diameter of the wire A to be inserted. The guide surface 27 is formed on a peripheral edge of the guide hole 25 on the outer end surface side of the guide member 23, for example, in a tapered shape that gradually narrows in a thickness direction from the outer end surface of the guide member 23.

Further, as shown in FIG. 1, the guide member 23 also has a tapered guide surface 28 gradually narrowing in the thickness direction from the inner end surface on the inner end surface adjacent to the die 21 as well. Have been. Furthermore, a contact surface 2 for contacting the guide member 23 in the moving direction of the movable die 22 with respect to the fixed die 21 to which the guide member 23 is fixed.
9 are provided. That is, the guide member 23 is fixed to the fixed die 21 by the screw 24 from the thickness direction in a state where the contact surface 29 is in contact with the fixed die 21. Reference numeral 30 in the drawing denotes a groove formed in the guide member 23 to avoid interference with the rod 6a of the cylinder 6 to which the moving die 22 is attached.

The operation of the thus configured connector compression die 20 according to this embodiment will be described below. The connector 1 of the present embodiment is, for example, the same as the conventional connector shown in FIG. 9 and has a hole 2 for inserting one electric wire B and a groove 3 for inserting another electric wire A. belongs to.

The connector compression die 2 according to the present embodiment
In the case of compressing the connector 1 using the compression tool 4, the fixed die 21 is first attached to the inside of the tip of the arm 5 of the compression tool 4, and the moving die 22 is attached to the tip of the rod 6a of the cylinder 6 of the compression tool 4. Attach. The compression tool 4 is attached to a tip of a manipulator (not shown). The guide member 23 in a state where the contact surface 29 is in contact with the fixed-side die 21 is fastened on both sides in the width direction by screws 24.
Keep it fixed.

Then, by operating the cylinder 6, the moving die 22 is moved, and both dies 21, 22 are moved.
The space for connector insertion defined by the compression surfaces 21a, 21a is, as shown in FIG.
The two dies 21 and 22 are separated from each other to a position substantially equal to the size of the guide hole 25. Alternatively, the dies 21 and 22 are automatically set with the cylinder 6 as a spring return type.
The distance between them may be set as described above. As a result, the guide member 23 is disposed so as to be stretched over the side surfaces of the dies 21 and 22.

In this state, the connector 1 temporarily attached to one electric wire B is inserted from one guide member 23 side along the width direction of the dies 21 and 22 as shown by arrows in FIG. The insertion operation is performed by a manipulator. At this time, the operator operates the manipulator on the ground while checking the postures of the connector 1 and the compression tool 4 on a CRT.

In this case, the operator adjusts the posture of the connector 1 so that the connector 1 can be inserted into the guide hole 25 of the guide member 23 attached to the fixed die 21. In the connector compression die 20 according to the present embodiment, since the guide surface 27 is provided on the periphery of the guide hole 25, the worker does not need to completely match the posture of the connector 1 with respect to the guide hole 25. In this case, the position may be adjusted with such accuracy that the tip of the connector 1 comes into contact with the guide surface 27.

Next, the connector 1 whose position has been adjusted to such an extent that the tip abuts on the guide surface 27 is moved to approach the connector compression die 20. Then, the distal end of the connector 1 comes into contact with the guide surface 27 of the guide member 23. However, since the guide surface 27 is formed in a tapered shape gradually narrowing in the thickness direction,
The distal end of the connector 1 is guided into the guide hole 25 following the guide surface 27 as indicated by an arrow in FIG. And
When the connector 1 is moved in the same direction, the connector 1 is fitted into the guide hole 25.

The dimensions of the guide hole 25 are determined by the connector 1 before compression.
The connector 1 fitted in the guide hole 25 is restrained from rotating about the longitudinal axis because the connector 1 is formed in a slightly larger dimension in accordance with the outline shape of the connector 1. Then, in this state, when the connector 1 is further moved in the same direction, the connector 1 is moved to the compression portions 21a, 2a adjacent to the guide member 23.
It will be inserted between 2a while maintaining a proper posture.

Further, the connector 1 passing between the compression parts 21a, 22a reaches the inner surface of the guide member 23 attached to the opposite side of the fixed die 21.
A guide surface 28 having a tapered surface is also formed on the inner periphery of the guide hole 25 of the connector 1.
The guide member 23 is inserted into the guide hole 25 without being caught by the guide member 23. In this state, the groove 3 of the connector 1 matches the gap between the dies 21 and 22, as shown in FIG. 3, so that another electric wire A can be inserted into the groove 3 through the gap. It is arranged in.

In this manner, the connector 1 is inserted in a state where its posture with respect to the dies 21 and 22 is properly positioned.
By supplying a relatively small pressure to the movable die 22 and pressing it against the connector 1 with a small force, the connector 1 is gripped between the dies 21 and 22.

Then, the dies 21, 22 are prepared in this manner.
The connector 1 gripped in between is moved by operating the manipulator, and as shown in FIG.
Another electric wire A is inserted into the groove 3 of the connector 1 through the gap 2. Thereafter, by supplying a predetermined pressure to the cylinder 6 of the compression tool 4, the connector 1 is compressed together with the electric wires A and B, and one electric wire A and another electric wire B are crimped.

In this case, when the movable die 22 is moved, the connector 1 pressed by the movable die 22 is guided by the guide holes 25 of the guide member 23 disposed flush with the fixed die 21 and its compression surface 21a. Will be pressed,
Since the guide member 23 is provided with the contact surface 29 that comes into contact with the fixed die 21 in the moving direction of the movable die 22, the pressing force from the connector 1 is received by the contact surface 29. Therefore, the screw 24 that fixes the guide member 23 to the fixed die 21 includes the cylinder 6
No pressing force acts, so that a healthy state is maintained.

After that, the pressure supply to the cylinder 6 of the compression tool 4 is stopped and the movable die 22 is moved in a direction to separate from the fixed die 21, thereby completing the pressure bonding operation. That is, if the electric wire B to be temporarily attached to the connector 1 is a branch line, and the electric wire A to be inserted into the groove 3 of the connector 1 is a main line later, the main line A is removed by using the connector compression die 20 according to the present invention. The branch line B can be easily and reliably branched.

In the connector compression die 20 according to the present embodiment, the guide members 23 are provided on both sides in the width direction of the fixed die 21. Instead, the guide members 23 are provided in any one of the width directions. It may be. In such a case, the guide surface 28 may not be provided on the side adjacent to the die 21. Further, the tapered guide surfaces 27, 28 are formed on the periphery of the guide hole 25 of the guide member 23. Even if the taper angles of the guide surfaces 27, 28 are constant,
It may change uniformly.

Next, a connector compression die according to a second embodiment of the present invention will be described with reference to FIGS. The connector compression die 3 according to the present embodiment
In FIG. 1, the same reference numerals are given to portions having the same configuration as the connector compression die 20 according to the above-described first embodiment, and the description is simplified. The connector compression die 31 according to the present embodiment is different from the connector compression die 20 according to the first embodiment described above in the mounting structure of the guide member 23.
Is different.

The connector compression die 3 according to the present embodiment
As shown in FIG. 4, the first guide member 23 is attached to both sides of the fixed die 21 in the width direction so as to be linearly movable along the movement axis of the two dies 21 and 22. That is, both dies 2 penetrating the guide member 23 in the thickness direction are provided.
Two elongated holes 32 extending in the direction of the movement axis of the fixed die 21 are provided in the elongated holes 32 so that the guide member 23 can be held in contact with the side surface of the fixed die 21. Is inserted. Accordingly, the guide member 23 can linearly move in the moving axis direction of the moving die 22 within a range in which the bolt 33 can move in the elongated hole 32.

A moving means 34 is incorporated in the guide member 23. This moving means 34 is, for example, as shown in FIG.
As shown in FIG.
A block 36 to be fitted in the inside, a flanged pin 37 inserted removably into a hole 36a formed in the block 36, and a coil spring for urging the flanged pin 37 to project from the block 36. And urging means 38.

The connector 1 is connected to the electric wires A and B by the connector compression die 31 according to the present embodiment thus configured.
The case of crimping to the surface will be described below. When the crimping operation is performed by the connector compression die 31, first, as shown in FIG. 6, the cylinder 6 (see FIG. 3) of the compression tool 4 (see FIG. 3) is actuated to thereby move the moving-side die. The space 22 is moved in a direction away from the fixed die 21 so that a space necessary for inserting the connector 1 between the compression surfaces 21 a and 22 a of the dies 21 and 22 is formed between the dies 21 and 22.

At this time, since only the urging force of the urging means 38 of the moving means 34 is acting on the guide member 23, the guide member 23 has its guide hole 25 as shown in FIG. , Compression surfaces 21a and 22 of both dies 21 and 22
It will be moved to the position corresponding to a. Thereby, the connector compression die 2 according to the first embodiment is formed.
0, the connector 1 to which the electric wire B is temporarily attached is inserted into the guide hole 2
5 easily along the guide surfaces 27, the compression surfaces 21a, 22a
Can be inserted in between.

The connector 1 is connected to the compression surfaces 21a, 22
In the state inserted between the connectors a, the low pressure was supplied to the cylinder 6 of the compression tool 4 to grip the connector 1 and the electric wire A was inserted into the groove 3 of the connector 1 in the same manner as in the first embodiment. Later, by supplying a high pressure to the cylinder 6 of the compression tool 4, the connector 1 is compressed together with the two electric wires A and B, and the electric wires A and B are mechanically and electrically crimped.

In this case, the connector 1 may have a step between the compressed portion disposed between the dies 21 and 22 and the non-compressed portions disposed on both sides thereof. The uncompressed portion of the connector 1 presses the guide member 23. However, according to the connector compression die 31 of the present embodiment, since the guide member 23 is provided so as to be movable, when the pressing force from the connector 1 is applied,
As shown in FIG. 7, the guide member 23 is provided with biasing means 38.
Is moved against the urging force of As a result, an excessive pressing force from the connector 1 is prevented from being applied to the guide member 23 and the screw 33 attaching the guide member 23 to the fixed die 21, and these parts are maintained in a healthy state. Will be.

Further, according to the connector compression die 31 according to the present embodiment, in order to remove the connector 1 after the crimping operation from between the dies 21 and 22, the moving side die 2 is used.
When the second member 2 is moved in a direction to separate from the fixed die 21, the pressing force applied to the guide member 23 from the connector 1 is also removed, and the guide member 23 is moved by the urging means 38 of the moving means 34 in FIG. It is returned to the position. Thereby, the guide hole 25 of the guide member 23 is connected to the compression surface 2 of the dies 21 and 22 opened to receive the next connector 1.
1a and 22a, the compression work of the next connector 1 can be continuously performed.

Next, a third embodiment of a connector compression die according to the present invention will be described with reference to FIG.
The connector compression die 40 according to the present embodiment includes a first,
Connector compression dies 20, 31 according to the second embodiment
Instead of the guide member 23, tapered guide surfaces 41 and 42 are provided on both side surfaces of the dies 21 and 22 in the width direction.
An attachment member 43 is provided between the first and second members.

The guide surfaces 41 and 42 are provided with the first and second guides.
The same operation and effect as those of the guide surface 27 of the guide member 23 of the connector compression dies 20 and 31 according to the embodiment are achieved. The contact member 43 is, for example, a thin plate member fixed to both side surfaces of the fixed die 21,
Both dies 2 on the contact surface 9 (see FIG. 10) side of the compression tool 4
Both dies 21 and 22 are closed so as to close the gap between the two dies 21 and 22.
It is hung between two. As a result, the attaching member 4
3 and the guide surfaces 41 and 42 define a guide hole 44 similar to the guide hole 25 in the connector compression dies 20 and 31 according to the first and second embodiments.

According to the connector compression die 40 according to the present embodiment having the above-described configuration, the first and second first holes are formed by the guide holes 44 formed by the attachment members 43 and the guide surfaces 41 and 42. Connector compression dies 20, 31
Similarly to the above, since the insertion of the connector 1 can be easily and reliably performed, there is an effect that occurrence of poor compression or the like can be prevented. Further, since the guide surfaces 41, 42 are formed directly on the side surfaces of the dies 21, 22, the screws 24, 33 fastening the guide member 23 as in the first and second embodiments are protected. No countermeasures are required, and the structure can be made extremely simple.

In the connector compression die 40 according to the above embodiment, the guide surfaces 41 and 42 may be provided on the movable die 22, and may be provided only on one side of the fixed die 21 or the movable die 22. It is also possible. In addition, the shape of the attaching member 43 is the die 2
It goes without saying that any material can be adopted as long as it can close the gap between the contact surfaces 9 and 12 on the contact surface 9 side.

[0062]

As described above, according to the connector compression die according to the present invention, the guide member is guided by inserting the connector between the dies from the guide member side attached to one of the pair of dies. Since the connector is disposed in a state where the connector is properly positioned with respect to the die by the means, there is an effect that it is possible to reliably avoid a disadvantage that the connector is incompletely compressed in the subsequent compression work. In addition, when positioning the connector with respect to the die, a method is adopted in which the outer surface of the connector is fitted into the guide hole, so that the inner surface of the connector, which is usually coated with a paste-like conductive material, is not used. Also, there is an effect that a good connection state can be maintained.

If the guide means of the guide member is constituted by a guide surface formed on the peripheral edge of the guide hole and gradually narrowing toward the die, the connector can be very simply and effectively inserted into the guide hole. Can be led to. as a result,
The present invention has an effect that the connector can be easily and appropriately arranged between the dies even in a remote operation in which an operator cannot directly operate by hand.

Further, if the guide members are provided on both sides in the width direction of the die, the connector can be inserted between the dies from either side in the width direction of the die, and can be inserted between the dies according to the posture of the connector. The insertion direction of the wire can be appropriately selected, and the crimping operation of the electric wire, particularly, the operation by remote control can be facilitated.

When the guide member is provided on both sides in the width direction of the die as described above, the guide surface gradually expanding toward the die along the insertion direction of the connector is provided on the periphery of the guide hole of the guide member on the die side. Is provided, the connector penetrating the die is smoothly inserted into the guide hole without being caught by the guide member disposed on the other side in the width direction of the die, so that the workability can be further improved. it can.

Further, by providing the guide member with an abutment surface, an external force acting on the guide member during compression work can be received by the abutment surface, and a fastener or the like that attaches the guide member to the die can be sound. This has the effect of being able to maintain the state.

Further, if the guide member is attached to one of the dies so as to be relatively movable in the direction in which the two dies come into contact with or separate from each other, even if the guide member is pressed by the connector, the guide member can be moved relative to the die. Since the pressing force can be released and an excessive force acting on the guide member can be avoided, there is an effect that the soundness of each member can be maintained.

Further, in that case, there is provided moving means for moving the guide member so that the guide hole coincides with the compression surface when the die is separated to receive the connector between the compression surfaces. With this, the guide member can be arranged at an appropriate position for inserting the connector between the compression surfaces by operating the moving means only by separating the die, and the crimping operation of the next connector can be continued. There is an effect that it can be implemented efficiently. Further, if the moving means is constituted by an urging means disposed between the guide member and one of the dies to which the guide member is attached, the above-described effect can be achieved with a simple structure.

Each of the dies is provided with a U-shaped compression surface and a guide surface that gradually widens outward in the width direction, and one of the dies is compressed together with the guide surface so as to span the side surfaces of both dies. In addition to the above-described effects, the structure can be made extremely simple if the outer surface of the previous connector is fitted to fix the attached member constituting the guide hole to be inserted while restraining rotation about the longitudinal axis thereof. There is an effect that can be.
