On the lower surface of the long box-shaped feed member 31 shown in FIG. 7, a moving groove (formed of a slope groove 31A and a straight groove 31B) bent in a sawtooth shape is continuously and repeatedly provided at the same pitch. The slide pin 21E engages with the moving groove. Of the moving grooves, the slope groove 31A has a specific angle θ.
The opening is opened in a direction inclined at an appropriate angle at which the slide pin 21E is easy to move, and the straight groove 31B is opened in a direction (Y direction) coinciding with the moving direction of the moving element 21D.

In FIG. 6, a circular shape is formed on the bottom surface of the feed member 31 so that the tip of the lock pin 21F is engaged with the feed member 31 to temporarily lock the feed member 31 on the wiring board 21 at a constant pitch. A plurality of recesses are provided in the feed direction. In contrast, the operating principle diagram of Fig. 7 a stone 12,
It is described that the engaging groove 31C having a V-shaped cross section is provided not on the lower surface of the feed member 31 but on the side surface for convenience, but the operation effect is not changed.

On the upper surface of the feed member 31 shown in FIG. 8, a base 41 on which a plurality of (10 in this embodiment) cable cores 10A are arranged at a constant pitch, and a lid which fits over the base 41 A stage 31D is provided for mounting the connector 4 comprising the connector 42. A plurality of (ten in this embodiment) cable cores 10A are arranged and pinched at regular intervals along the longitudinal direction between the base 41 and the lid 42 of the rectangular parallelepiped connector 4 of the present invention. It is.

The feed mechanism 3 of this embodiment uses a unique mechanism (invented by the inventor) which will be described later, and can be operated by a simple pushing operation with a finger. (For the detailed operation, see the constant pitch feed mechanism filed by the same applicant on the same date), but of course, the present invention is not limited to this configuration.

Next, the operation of the apparatus of this embodiment will be described separately for the crimping action of the connector 4 and the constant pitch feeding action of the connector 4. Although only the crimping mechanism is operated by the operation lever in this embodiment, both the crimping operation and the feed mechanism may be operated by the operation lever.

1, the base 41 of the connector 4 is mounted on the stage 31D (see FIG. 8) of the feed mechanism 3 (feed member 31) set at a predetermined position on the upper surface of the wiring board 21 in FIG. At the same time, the end side of the cable core wire 10A is arranged on the connection conductor of the base 41, and the lid 42 is pushed in with a finger or the like from above and temporarily fixed.

Next, the crimping mechanism 2 for a connector is operated, that is, the pair of operating levers 24 are closed while their hands are being gripped by hand. Then, by this closing operation, the toggle joint 23 operates, and the push rod 21A connected to the toggle joint 23 moves upward as shown in FIG. 2, so that the wiring board 21 is pushed upward. It will be.

Along with the pushing-up operation of the wiring board 21, the connector 4 on the feed member 31 is pushed upward, and the lower surface of the crimping head 22 immediately above is part of the lid 42 (corresponding to one cable core 10A). Part). As a result, the pressing portion of the lid 42 is completely pressed against the base 41, and the cable core 10A held here is pushed into the slit hole formed in the connector terminal, thereby being connected to the connector 4. The Rukoto.

Next, the feed operation of the feed mechanism 3 on which the connector 4 is mounted will be described with reference to the principle diagrams of FIGS. 9 to 12. Cable core 10
The connector 4 is pitch-fed at the same pitch as the arrangement interval of A. For convenience of explanation in this embodiment, in the principle diagram to Figure 9: Figure 11, the feed member 31
Omitting to draw the full length, draw only two pitches of the moving groove
It is. For convenience, it is different from the configuration in which the pressing spring 21C has been already described, no difference is acting on the slide pin 21 E.

First, in FIG. 9, the feed member 31 is locked and temporarily fixed by a lock pin 21F at a predetermined rightmost position, and is sent out to the left by one pitch in the following. The situation when one pitch is fed out will be described below.

As shown in FIG. 10, when the pushing member 32 is pushed to the left once with a finger against the elastic force of the feeding spring 33, the feeding member 31 connected to the pushing member 32 and the feeding spring 33 also moves to the left. Try to move to. Here, since the projection 32A on the lower surface of the pushing member 32 also moves in the same direction, the projection 32A on the leftmost side becomes the slope groove 31A on the leftmost side.
, And the slope groove 31A is opened.

Here, a slide pin (slide groove 21B)
(Refer to FIG. 4) The movement direction is limited to the Y direction.)
9, the leftmost position of the slope groove 31A is pushed in by the action of the pressing spring 21C in FIG. 9, but with the movement of the feed member 31, the pressing force of the pressing spring 21C is rejected in FIG. It is pushed up by the edge (lower edge indicated by α) of the slope groove 31A on the left end side, and moves obliquely rightward along the slope groove 31A. At this time, the feed member 31 moves one pitch to the left.

As a result, as shown in FIG. 11, the slide pin 21E enters the straight groove 31B on the leftmost side, but immediately the lower end of the straight groove 31B (the last slope groove 31A next to the leftmost one) is pressed by the pressing spring 21C. (Lower).

In synchronization with the movement of the feed member 31,
Since the lock pin 21F also engages with the engagement groove 31C adjacent to one pitch, the feed member 31 is locked there and temporarily fixed. In this manner, the feed member 31 can be sent to the left by one pitch.

When the finger is released from the pushing member 32, the pushing member 32 returns to the right with respect to the sending member 31 and returns to the original position by the elastic force of the sending spring 33 as shown in FIG. Hereinafter, by the same operation, the feed member 31 can be sent to the left by one pitch each time.

Therefore, according to the apparatus of this embodiment, every time the connector 4 moves on the wiring board 21 at a constant pitch (core interval), the crimping head 22 is connected to each cable core 10A each time.
Is pushed into the base 41 side sequentially (therefore, the lid 42 is inclined obliquely at the boundary between the press-bonded portion and the non-pressed portion), and the core unit is Then, the lids 42 are individually crimped to the base 41, and at the same time, each cable core 10A is connected to the terminal of the connector 4. Almost at the same time, by the cutter 1C,
Excess portions of the connected cable cores 10A are also sequentially and individually cut off.

Further, according to this embodiment, since the operation lever 24 operates the crimping mechanism 2 via the toggle joint 23, a large crimping force can be exerted with a small operation force by the principle of leverage. , A reliable crimping operation can be realized.

[0026]

As described above, according to the present invention, a connector is fixed and mounted on a wiring board, and a cable core to be connected to a base of the connector is arranged.
The connector is successively sent out at the arrangement pitch of the cable cores by the feed mechanism, and the corresponding portion of each cable core of the connector is sequentially crimped by the crimping mechanism, and the desired cable core is electrically connected to the connector by the crimping operation. In other words, the cable cores can be individually connected to the connector by extremely simple operation with a hand or a finger without the need for complicated various devices.

Further, according to the present invention, since the cable cores are individually connected to the connector using the crimping mechanism, a small force is not required as in the case of simultaneous collective connection. The cable core can be connected with a simple operation force.
