Description

The present invention relates to a terminal crimping device that crimps terminals to the ends of electric wires.

The crimp terminal attached to the end of the electric wire has a crimping portion that is crimped to the electric wire. The crimping portion has a crimping piece having a substantially U-shaped cross section. When crimping the crimping piece of the crimping portion to the electric wire, the crimping piece is placed on the anvil with the electric wire arranged inside, and the crimper above the anvil is lowered. As a result, both ends of the crimping piece are curved inward by the crimper and crimped, and the crimped portion is crimped to the electric wire (for example, Patent Document 1).

By the way, when the crimper is lowered with respect to the anvil, the crimping portion of the crimp terminal to which the compressive load from the crimper is applied and the core wire of the electric wire are crushed in the load direction and deformed into a thin plate shape. This deformation is caused by crimping the crimping terminal core wire crimping part (forefoot part) to the wire core wire with the insulation coating removed, even when crimping the crimping terminal core wire crimping part (rear foot part) to the wire insulation coating. It also occurs when crimping a part).

In particular, in the latter case where the crimped portion and the insulating coating come into contact with each other, the elasticity of the insulating coating made of resin can buffer the compressive load of the crimper to some extent. However, in the former case where the crimped portion and the core wire are in direct contact with each other, the compressive load of the crimper is hardly buffered between the crimped portion and the core wire, so that the crimped portion and the core wire are deformed by that amount. To do.

Further, thinning due to deformation of the crimped portion and the core wire may cause a decrease in their rigidity, and it is particularly desirable to avoid these in recent years when it is required to reduce the size and weight of parts.

The present invention has been made in view of the above circumstances, and an object of the present invention is a terminal crimping device capable of suppressing the crimping terminal and the electric wire from being crushed and thinned by a compressive load when crimping the crimping terminal to an electric wire. Is to provide.

In order to achieve the above object, the terminal crimping device according to the first aspect of the present invention is
Anvil that supports the crimping part of the crimping terminal that is crimped to the electric wire,
An anvil holder that supports the anvil so that it can be raised and lowered,
A crimper which is arranged so as to be able to move up and down with respect to the anvil holder and is lowered so as to approach the anvil holder to crimp the crimping portion supported by the anvil and crimp it to the electric wire.
An anvil-side elastic member interposed between the anvil and the anvil holder and urging the anvil so as to protrude from the anvil holder toward the anvil.
To be equipped.

According to the terminal crimping device according to the first aspect of the present invention, when the crimp descends so as to approach the anvil and the crimping portion of the crimp terminal supported by the anvil is crimped, the compressive load applied from the crimp to the crimp terminal causes the crimp. Stress is generated in the crimped part. Due to the stress generated in the crimped portion, the anvil supporting the crimped portion descends with respect to the anvil holder against the urging force of the elastic member on the anvil side.

Then, the elastic member on the anvil side contracts due to the lowered anvil, and elastic force is generated in the elastic member on the anvil side that has contracted. The elastic force of the elastic member on the anvil side is applied to the anvil from the elastic member on the anvil side as a reaction force against the stress applied from the crimping portion. Therefore, the anvil is arranged at a position where the stress from the crimping portion and the reaction force from the elastic member on the anvil side are balanced.

Therefore, when an excessive compressive load is applied from the crimper to the crimped portion, the elastic member on the anvil side that urges the anvil to the crimper side contracts with a stroke corresponding to the magnitude of the compressive load from the crimper, and the crimper. Absorbs excessive compressive load from. By absorbing the excessive compressive load from the crimper by the elastic member on the anvil side, the crimp terminal crimping portion and the electric wire to which the crimping portion is crimped are protected from the application of the excessive compressive load by the crimp.

Therefore, it is possible to prevent the crimping terminal crimping portion and the electric wire from being crushed and thinned by the compressive load when the crimping terminal crimping portion is crimped to the electric wire.

Further, in the terminal crimping device according to the second aspect of the present invention, the crimping terminal is left with the first crimping portion crimped to the core wire from which the insulating coating at the tip of the electric wire has been peeled off, and the electric wire without being peeled off. It has a second crimping portion that is crimped to the insulating coating, and the anvil supports at least a portion of the crimp terminal from the first crimping portion to the second crimping portion. Then, the crimp crimps the first crimping portion and the second crimping portion supported by the anvil.

According to the terminal crimping apparatus according to the second aspect of the present invention, the first crimping portion and the second crimping portion of the crimping terminal have a core wire and an insulating coating of electric wires having different diameters depending on the presence or absence of an insulating coating. Each is tightened. Therefore, when the core wire and the insulating coating of the electric wire are crimped by the compressive load from the dropped crimper, different stresses are applied to the first crimping portion and the second crimping portion of the crimp terminal. Occurs.

Here, if the anvil supporting the first crimping portion and the anvil supporting the second crimping portion are separate bodies and are individually supported by the anvil holder, each anvil corresponds to each other. Due to the stress of the crimping part, it descends with a different stroke against the urging force of the elastic member on the anvil side. As a result, the positions of the first crimping portion and the second crimping portion supported by the anvil are displaced in the elevating direction of the anvil, and the crimp terminal is bent up or bent down.

However, since the first crimping portion and the second crimping portion of the crimp terminal are supported by the same anvil, the position of the portion supported by the anvil is anvil even if the stress generated in each crimping portion is different. There is no deviation in the ascending / descending direction of. Therefore, it is possible to prevent bend-up and bend-down from occurring in the crimp terminal.

Further, the terminal crimping device according to the third aspect of the present invention is arranged so as to be able to move up and down with respect to the anvil holder, supports the crimper so as to be able to move up and down, and descends together with the crimper so as to approach the anvil holder. As a result, the crimper is interposed between the crimper holder and the crimper holder for crimping the crimping portion supported by the anvil and crimping the crimping portion to the electric wire, and the crimper is attached to the crimper holder. It is further provided with an elastic member on the crimper side that urges the anvil side to project from the side.

According to the terminal crimping device according to the third aspect of the present invention, the stress generated in the crimped portion of the crimping terminal on the anvil that has been crimped by the descent of the crimper resists the urging force of the elastic member on the anvil side. Is lowered with respect to the anvil holder, and the crimp is raised with respect to the crimp holder against the urging force of the elastic member on the crimp side.

Therefore, on the elevated crimper side, the crimper side elastic member contracts due to the crimper, and the contracted crimper side elastic member generates elastic force. This elastic force is applied to the crimper from the elastic member on the crimper side as a reaction force against the stress applied from the crimping portion. As a result, the crimper is arranged at a position where the stress from the crimping portion and the reaction force from the elastic member on the crimper side are balanced.

Therefore, if the compressive load applied by the crimper holder to the crimped portion via the crimper is excessive, the elastic member on the crimper side contracts together with the elastic member on the anvil side with a stroke corresponding to the descent stroke of the crimper holder, and the crimper. Absorbs the excessive compressive load applied to the crimping part. Therefore, the crimping terminal crimping portion and the electric wire to which the crimping portion is crimped are more efficient because an excessive compressive load is applied due to the lowering of the crimp holder due to the contraction of the elastic member on the anvil side and the elastic member on the crimper side. Protected by.

Therefore, it is possible to more reliably prevent the crimping terminal crimping portion and the electric wire from being crushed and thinned by the compressive load when the crimping terminal crimping portion is crimped to the electric wire.

According to the present invention, it is possible to prevent the crimp terminal and the electric wire from being crushed and thinned by the compressive load when the crimp terminal is crimped to the electric wire.

The anvil unit 7 has the same width as the width in the state where the electric wire 3 of the crimp terminal 5 is crimped and crimped in the front and back directions of the paper surface of FIG. 1 (see FIGS. 2 and 4).

The anvil unit 7 has an anvil 71 that supports the forefoot portion 55 of the crimp terminal 5 on the upper surface 71a, and an anvil holder 73 that supports a portion of the crimp terminal 5 excluding the forefoot portion 55 on the upper surface 73a. The anvil holder 73 is fixed, and the anvil 71 is supported so as to be able to move up and down in a guide groove 75 that opens in the upper surface 73a of the anvil holder 73.

In the guide groove 75, the anvil 71 projects upward from the opening of the guide groove 75 by a coil spring 77 (corresponding to the elastic member on the anvil side in the claim) arranged between the anvil holder 73 and the anvil holder 73. Being urged in the direction. The removal of the anvil 71 from the guide groove 75 is prevented by engaging a stopper piece (not shown) provided in the anvil 71 with the inner wall of the guide groove 75.

A locking projection 71b is provided so as to project from the upper surface 71a of the anvil 71.

The crimper holder 93 is arranged above the anvil holder 73 so as to be able to move up and down. As shown in FIG. 2, which is a cross-sectional view taken along the line II of FIG. 1, a crimping groove 93b is formed on the lower surface 93a of the crimper holder 93. When the crimp terminal 5 is crimped to the electric wire 3, the anvil unit 7 is inserted into the crimping groove 93b as the crimp holder 93 descends with respect to the anvil holder 73.

As shown in FIG. 1, a clearance portion 93c and a hind foot crimping portion 93d are provided at the upper end of the crimping groove 93b.

Has been done. The removal of the crimper 91 from the guide groove 95 is prevented by engaging a stopper piece (not shown) provided in the crimper 91 with the inner wall of the guide groove 95.

A guide surface 91a is formed at the lower end of the crimper 91. As shown in FIG. 2, the guide surface 91a has two arc portions 91b and 91c having different curvatures.

Next, the operation of the terminal crimping device 1 when crimping the crimping terminal 5 to the electric wire 3 using the terminal crimping device 1 of the present embodiment will be described.

First, with the crimper holder 93 located at the upper limit of the elevating range, the recess 55b of the forefoot portion 55 is locked to the locking projection 71b of the anvil 71, and the crimp terminal 5 is placed on the upper surface 73a of the anvil holder 73. The crimp terminal 5 is supported by the anvil 71 and the anvil holder 73. At this time, the upper surface 71a of the anvil 71 that supports the forefoot portion 55 is located above the upper surface 73a of the anvil holder 73, as shown in the explanatory view of FIG. 4 (a).

Then, with the crimp terminal 5 supported by the anvil 71 and the anvil holder 73, the crimp holder 93 is lowered toward the anvil holder 73.

When the crimper holder 93 is lowered, the tips of both crimping pieces 55c and 55d come into contact with the crimping groove 93b of the crimp holder 93 on the forefoot portion 55 side of the crimp terminal 5. A compressive load from the crimper holder 93 is applied as stress to the forefoot portion 55 where both the crimping pieces 55c and 55d are in contact with the crimping groove 93b as the crimper holder 93 descends.

The compressive load from the crimper holder 93 is transmitted to the coil spring 77 of the anvil unit 7 via the anvil 71 that supports the forefoot portion 55, and causes the coil spring 77 to contract. A resilient force is generated in the contracted coil spring 77. The elastic force of the coil spring 77 is applied to the anvil 71 from the coil spring 77 as a reaction force to the compressive load transmitted from the forefoot portion 55 via the anvil 71. Therefore, the anvil 71 is arranged at a position where the compressive load from the forefoot portion 55 and the elastic force of the coil spring 77 are balanced.

Therefore, when an excessive compressive load is applied from the crimper holder 93 to the forefoot portion 55, the coil spring 77 of the anvil unit 7 contracts with a stroke corresponding to the magnitude of the compressive load from the crimper holder 93, and the crimper holder Absorbs excess compressive load from 93.

Then, both crimping pieces 55c and 55d of the forefoot portion 55 have a clearance portion due to a compressive load from the crimper holder 93 after the excess is absorbed by the coil spring 77 of the anvil unit 7 while the crimper holder 93 is descending. Slide on the crimping groove 93b until it approaches 93c. By sliding on the crimping groove 93b, both crimping pieces 55c and 55d are deformed inward until they have a shape that can be inserted into the guide groove 95.

When the crimper holder 93 is further lowered, both the crimping pieces 55c and 55d deformed inward by sliding on the crimping groove 93b are inserted into the guide groove 95. The tips of both crimping pieces 55c and 55d inserted into the guide groove 95 come into contact with the arc portions 91b and 91c of the crimper 91, respectively.

The compressive load applied as stress from the crimper holder 93 to the forefoot portion 55 where both crimping pieces 55c and 55d are in contact with the arc portions 91b and 91c of the crimper 91 is the crimping groove as the amount of descent of the crimper holder 93 increases. It increases more than the compressive load applied from the crimper holder 93 when both crimping pieces 55c and 55d are in contact with 93b.

Here, in a state where both the crimping pieces 55c and 55d are in contact with the arc portions 91b and 91c of the crimper 91, respectively, the compressive load from the crimper holder 93 contracts the coil spring 97 of the crimper unit 9. A resilient force is generated in the contracted coil spring 97. The elastic force of the coil spring 97 is applied from the coil spring 97 to the crimper holder 93 as a reaction force against the compressive load from the crimper holder 93. Therefore, the crimper 91 is arranged at a position where the compressive load from the crimper holder 93 and the elastic force of the coil spring 97 are balanced.

Therefore, in a state where both crimping pieces 55c and 55d are in contact with the arc portions 91b and 91c of the crimper 91, if the compressive load from the crimper holder 93 is excessive, the coil spring 97 of the crimper unit 9 is crimped. It contracts with a stroke corresponding to the magnitude of the compressive load from the holder 93 to absorb the excessive compressive load from the crimper holder 93.

Even when both crimping pieces 55c and 55d are in contact with the arc portions 91b and 91c of the crimper 91, the coil spring 77 of the anvil unit 7 is transmitted from the crimper holder 93 via the forefoot portion 55 and the anvil 71. Shrinks due to the compressive load of. Therefore, the excessive compressive load from the crimper holder 93 is also absorbed by the coil spring 77 of the anvil unit 7.

Then, both the crimping pieces 55c and 55d of the forefoot portion 55 are removed from the crimper holder 93 after the excess is absorbed by the coil springs 77 and 97 of the anvil unit 7 and the crimper unit 9 while the crimper holder 93 is descending. Due to the compressive load, it slides on the arc portions 91b and 91c of the crimper 91. Both crimping pieces 55c and 55d are deformed inward in an arc shape by sliding on the arc portions 91b and 91c, respectively.

At this time, the other crimping piece 55d deformed into an arc shape by the arc portion 91c having a large curvature is one that is deformed into an arc shape by the arc portion 91b having a small curvature, as shown in the explanatory view of FIG. 4 (b). It is wound around the outside of the crimping piece 55c.

Then, when the crimper holder 93 is lowered to the bottom dead center, as shown in the explanatory view of FIG. 4C, both crimping pieces 55c and 55d are crimped to the core wire 33 of the electric wire 3 by the anvil 71 and the crimper 91. Is crimped.

At this time, as shown in FIG. 1, the connecting portion 53 and the connecting portion 57 of the crimp terminal 5 connected to the forefoot portion 55 have a space between them and the clearance portion 93c of the crimper holder 93. Therefore, when the forefoot portion 55 is crimped to the core wire 33 of the electric wire 3 and crimped, the connecting portion 53 and the connecting portion 57 of the crimping terminal 5 facing the clearance portion 93c do not interfere with the crimper holder 93.

On the other hand, on the hind foot portion 59 side of the crimp terminal 5, when the crimper holder 93 is lowered to the anvil holder 73 side, the tips of both crimping pieces 59b and 59c shown in FIG. 3 become the crimping groove 93b of the crimp holder 93. Contact. A compressive load from the crimper holder 93 is applied as stress to the hind foot portion 59 where both the crimping pieces 59b and 59c are in contact with the crimping groove 93b as the crimper holder 93 descends.

The compressive load from the crimper holder 93 is transmitted to the hind foot portion 59 supported by the anvil holder 73. Then, both the crimping pieces 59b and 59c of the hindfoot portion 59 slide on the crimping groove 93b by the compressive load from the crimper holder 93 until they approach the hindfoot crimping portion 93d while the crimper holder 93 is descending. .. By sliding on the crimping groove 93b, both crimping pieces 59b and 59c are deformed inward so as to wrap the insulating coating 31 of the electric wire 3.

Then, when the crimper holder 93 is further lowered, both the crimping pieces 59b and 59c deformed inward by sliding on the crimping groove 93b slide on the hind foot crimping portion 93d of the crimper holder 93. Both crimping pieces 59b and 59c sliding on the hind foot crimping portion 93d lower the crimper holder 93 to the bottom dead center so that the both crimping pieces 59b and 59c align their tips and insulate the electric wire 3 31. It is deformed inward so as to be thrust into the insulating coating 31 and crimped to the insulating coating 31.

As described above, in the terminal crimping device 1 of the present embodiment, the anvil 71 that supports the forefoot portion 55 of the crimp terminal 5 is anviled by the coil spring 77 in the anvil holder 73 that supports the anvil 71 so as to be able to move up and down. It was urged so as to protrude from the holder 73 toward the crimp holder 93.

Therefore, when the compressive load from the crimper holder 93 is excessive, the coil spring 77 contracts to absorb the excessive compressive load, and it is possible to prevent the excessive compressive load from being applied to the forefoot portion 55. Therefore, as compared with the case where the bottom portion 55a of the forefoot portion 55 is supported on a fixed plane, the bottom portion 55a of the forefoot portion 55 is suppressed from being crushed and deformed by the compressive load applied to the forefoot portion 55 at the time of crimping the core wire 33 of the electric wire 3. be able to.

In the terminal crimping device 1 of the above-described embodiment, the crimp 91 that applies a compressive load to the hind foot portion 59 of the crimp terminal 5 can be raised and lowered on the crimp unit 9 side as well as on the anvil unit 7 side. The coil spring 97 in the supporting crimp holder 93 is configured to urge the crimp holder 93 so as to protrude toward the anvil holder 73. However, this configuration may be omitted.

Further, in the above-described embodiment, the case where the present invention is applied to a portion where the forefoot portion 55 of the crimp terminal 5 is crimped to the core wire 33 of the electric wire 3 to be crimped has been described. However, the present invention can also be applied to a portion where the hind foot portion 59 of the crimp terminal 5 is crimped to the insulating coating 31 of the electric wire 3 to be crimped. Specifically, for example, as shown in the explanatory view of FIG. 5, the anvil 71 is configured to have a size capable of simultaneously supporting the forefoot portion 55 and the hindfoot portion 59 of the crimp terminal 5, so that the hindfoot portion 59 can be supported at the same time. The present invention can be applied to the crimped portion of.

In this case, the portion from the forefoot portion 55 to the hindfoot portion 59 supported by the anvil 71 of the crimp terminal 5 moves up and down integrally by the contraction of the coil spring 77 according to the strength of the compressive load from the crimper holder 93. .. Therefore, as compared with the case where the forefoot portion 55 is supported by the anvil 71 and the hindfoot portion 59 is supported by the anvil holder 73 as in the above-described embodiment, the amount of elevation of the forefoot portion 55 and the amount of elevation of the hindfoot portion 59 are increased. It is possible to suppress the occurrence of bend-up or bend-down in the communication unit 57 due to the difference from the above.

In FIG. 5, the coil spring 77 is set in the left-right direction in the drawing in order to make it easy to visually understand that the anvil 71 in the anvil holder 73 is urged toward the crimper holder 93 by a force that is evenly distributed. A total of four are arranged at equal intervals in the figure. However, the number of coil springs 77 may be 3 or less or 5 or more as long as the anvil 71 is urged by an evenly distributed force.

Further, the urging force per unit area of the upper surface 71a of the anvil 71 by the coil spring 77 is the same in both the terminal crimping device shown in FIG. 1 and the terminal crimping device 1 in which the anvil 71 is enlarged as shown in FIG.

The present invention is extremely useful in a terminal crimping device that crimps terminals to the ends of electric wires.
