Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a crimping device used when crimping a crimp terminal to an electric wire.

[0002]

[Prior art]

 A connector is used to connect the wires to each other, and a crimp terminal is attached to the end of the wire to electrically connect the wires to each other in the connector. The crimp terminal is attached to the electric wire by crimping it with a crimping machine. Normally, in this crimping operation, the crimping terminal is attached to the crimping machine along with the electric wire every time the work is performed.

[0003]

[Problems to be solved by the device]

 For this reason, when crimping crimp terminals to a large number of wires in succession, it takes time and labor, resulting in poor work efficiency.

Then, this invention aims at facilitating the crimping work of the crimp terminal to the electric wire.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a device body in which an electric wire is set from the outside with a crimp portion for crimping a crimp terminal to the electric wire, and a hydraulic mechanism portion for crimping the crimp portion. A plurality of the crimp terminals can be housed, and a cartridge for sequentially delivering the crimp terminals to the crimp portion as the electric wire is set in the apparatus body is detachably attached to the apparatus body.

[0006]

[Action]

 According to the crimping device having such a configuration, as the electric wire is set in the main body of the device, the crimping terminals are sequentially sent out from the cartridge and reach the crimping portion, and when the hydraulic mechanism is operated, the crimping portion operates. Then, the crimp terminal is crimped to the electric wire.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a crimping device showing an embodiment of the present invention, and FIG. 2 is a sectional view thereof. An insertion port 5 for the electric wire 3 is provided at the right end of the device body 1 in the figure. As shown in FIG. 3, a cartridge 9 containing a plurality of crimp terminals 7 is mounted in front of the insertion port 5 in the wire insertion direction. The cartridge 9 can be attached / detached from an attachment / detachment port 10 on a side portion of the apparatus main body 1, and a plurality of crimp terminals 7 stacked in the vertical direction are constantly urged upward by a spring 11 provided at a lower portion.

In the cartridge 9, openings 9 a 1 and 9 b are formed on both left and right sides of the uppermost crimp terminal 7 in the figure. A crimp terminal pusher 13 for pushing out the uppermost crimp terminal 7 in the cartridge 9 is installed at a position facing the opening 9b on the right side, while a crimp terminal pusher 13 is provided in front of the opening 9a on the left side. An inclined surface 15 formed on the frame in the apparatus body 1 through which the extruded crimp terminal 7 is guided is provided. An electric wire guide 17 into which the electric wire 3 is inserted is installed above the cartridge 9. As the electric wire 3 is inserted into the electric wire guide 17 through the insertion port 5, the crimping terminal push-out 13 causes the crimping terminal 7 to move. Is extruded to the inclined surface 15 side.

A crimp portion 19 for crimping the crimp terminal 7 to the electric wire 3 is provided further in front of the inclined surface 15. The crimping section 19 includes a lower die 19a fixed to a frame in the apparatus main body 1, and an upper die 19b that moves vertically to approach and separate from the lower die 19a to perform the crimping operation. A hydraulic mechanism section 23 is connected to the upper mold 19b via a link mechanism 21, and a hydraulic tube 25 connected to the hydraulic mechanism section 23 is drawn out from the upper surface of the apparatus main body 1 to the outside. A foot pedal 27 that operates the hydraulic mechanism 23 is attached to the end of the hydraulic tube 25 that is pulled out to the outside.

In the crimping device thus configured, when the electric wire 3 is inserted from the insertion port 5 of the device body 1, the tip of the electric wire 3 is guided by the electric wire guide 17 and reaches the crimping portion 19. At this time, as shown in FIG. 4, as the electric wire 3 moves in the electric wire guide 17, the crimp terminal push-out 13 pushes the uppermost crimp terminal 7 in the cartridge 9, and the pushed crimp terminal 7 tilts. It is carried to the crimping part 19 along the surface 15.

In this state, when the foot pedal 27 is stepped on, the hydraulic mechanism 23 is operated, the upper mold 19b is lowered via the link mechanism 21, and the crimp terminal 7 is pressed against the electric wire 3 with the lower mold 19a. Be worn. After the crimping is completed, when the electric wire 3 is pulled out from the device main body 1, the crimping terminal push-out 13 also returns to the original position shown in FIG. 3, and together with this, the plurality of crimping terminals 7 are entirely moved upward by the spring 11 and the next crimping Terminal 7 is set at the uppermost end and ready for the next crimp. When all the crimp terminals 7 in the cartridge 9 are used up and the crimping work is to be continued, the empty cartridge 9 is removed from the apparatus body 1 and the crimp terminals 7 are replenished. set.

In this way, when crimping the crimp terminal 7 to the electric wire 3, the electric wire 3 is inserted into the apparatus main body 1 with the cartridge 9 accommodating a plurality of crimp terminals 7 set in the apparatus main body 1. However, since it is only necessary to step on the foot pedal 27, it is not necessary to set the crimp terminal 7 each time crimping, even when crimping the crimp terminal 7 to a large number of electric wires continuously. The time required for the work is shortened, the work itself becomes easier, and the work efficiency is improved.

[0014] Incidentally, the cartridge 9 for accommodating the crimping terminal 7, Ru convenient der idea to make what cross-sectional area of the wire can cope with a variety of electrical wires, such as those of the ones and 1.25 mm ² 2 mm ^2. Further, if the cartridge 9 is prepared such that 20 crimp terminals 7 are accommodated, or 50 crimp terminals 7 are accommodated, and these are properly used, the working efficiency is improved.

[0015]

[Effect of device]

 As described above, according to the present invention, the plurality of crimp terminals housed in the cartridge are sequentially delivered to the crimp section, and the delivered crimp terminals are crimped to the electric wire by the hydraulic mechanism section. Therefore, the continuous crimping work can be performed easily in a short time, and the working efficiency can be improved.
