Means for Solving the Problems and Effects of the Invention The present invention relates to an invention of a method for manufacturing a terminal holder for a coupler connecting device, which overcomes such difficulties, and a coupler for fitting a large number of couplers in the width direction of the coupler. In the method of manufacturing a terminal holder having a fitting portion formed, leaving the ends of adjacent terminal plates connected to each other,
A metal plate is punched with a press, the terminal plate is cut and raised from the metal plate to form a terminal plate unit in which the plurality of terminal plates are connected in parallel to each other, and the terminal plate unit is fitted into a mold. Then, after injecting an insulating material into the mold and exposing the end portion of the terminal plate to the outside of the insulating material, after forming a terminal holder, the metal plate protruding portion exposed to the outside of the terminal holder is removed. The feature is that they are removed while being connected to each other.

According to the present invention, in a method of manufacturing a terminal holder in which a coupler fitting portion for fitting a large number of couplers respectively in the width direction of the coupler is formed, a metal plate is formed by leaving the ends of adjacent terminal plates connected to each other. Punching with a press and cutting and raising the terminal plate with respect to the metal plate to form a terminal plate unit in which the plurality of terminal plates are connected in parallel with each other, so that the terminal plate unit is fitted into a mold. Thus, it is possible to easily mount the plurality of terminal plates in a state where they are coupled to each other, without requiring a large number of steps.

Further, in the present invention, after the terminal plate unit is fitted in the mold, after the terminal holder is molded in a state where the insulating material is injected into the mold to expose the end of the terminal plate to the outside of the insulating material. Since the metal plate projecting portions exposed to the outside of the terminal holder are removed while being connected to each other, the metal plate projecting portions can be easily separated without any holding jig.

Further, according to the present invention, since the metal plate projecting portions of the terminal plate are removed while being connected to each other, the removed pieces do not become small foreign matters and enter the terminal holder.

As described above, according to the present invention, since many man-hours and a special holding jig are not required, productivity can be improved and cost can be reduced.

Moreover, according to the present invention, since the terminal holder is formed while the terminal plates are held in parallel with each other by the metal plate protrusions, the terminal plates are set in parallel with each other and their mutual intervals are set to accurate dimensions. It is possible to improve the quality of the terminal holder.

Embodiment An embodiment of the present invention shown in FIGS. 2 to 8 will be described below.

1 is a terminal in which a plurality of brass terminal plates 10 are integrally embedded at a required interval in a width direction oriented parallel to each other on a synthetic resin substrate 2 having a high electrical insulation property. It is a holder.

Reinforcing pieces 3 and 4 are integrally formed on the outer periphery of the substrate 2, and a peripheral wall 5 is integrally formed inside the reinforcing pieces 3 and 4,
The interior of the peripheral wall 5 is partitioned by a partition wall 6 into eight coupler fitting portions 7 having the same size and shape.

Further, each of the coupler fitting portions 7 has a coupler 14
The recessed portion 8 and the notched step portion 9 are formed integrally so that they can be fitted in the same direction.

Therefore, the terminal holder 1 is manufactured according to a manufacturing sequence as described below.

First, a brass plate is punched with a press as shown in FIG.
This is bent as shown in FIG. 7 to form the terminal plate 10, and the flat plate portion 11 of the terminal plate 10 is formed in the notch 13a and the notch 13b in the mold 13 as shown in FIG. Fit the base 12 and mold a flat plate not shown
After covering 13 the terminal plate 10
The terminal holder 1 is made in a state of being embedded in the insulating synthetic resin substrate 2, and the brass plate protruding portion 10a exposed from the substrate 2 is cut off.

Next, on the outer peripheral surface of the coupler 14, a protrusion 15 and a notch (not shown) that can be fitted into the recess 8 and the notch step 9 in the coupler fitting 7 are formed.

Further, in the coupler 14, the wire insertion holes 16 and the female terminal insertion holes 17 are formed under the terminal plates 10 at intervals equal to the arrangement intervals of the terminal plates 10. Notches 18 into which 10 can be loosely fitted are formed, and female terminals 20 are fitted in the female terminal insertion holes 17, respectively.

Further, the female terminal insertion hole 17 is formed with a retaining locking step portion 19, which is cut into the body 21 of the female terminal 20 when the female terminal 20 is inserted into the female terminal insertion hole 17 of the coupler 14. The raised terminal retaining piece 22 is engaged with the retaining locking step portion 19 so that the female terminal 20 can firmly hold the fitted state in the coupler 14.

Thus, the upper part 21a of the female terminal body 21 can hold the wire core wire 26 of the wire 25, while the lower part 21b of the body 21 can hold two holding pieces 23.

Further, each of the sandwiching pieces 23 is curved in a U-shape facing the facing surface, and the curved portion 23a of the sandwiching piece 23 has a curved portion 23a.
Both surfaces of the can be elastically contacted.

Since the embodiment shown in FIGS. 2 to 8 is configured as described above, the lower portion 21a of the female terminal body 21 is integrally caulked to the tip core wire 26 of the wire 25 projecting and branched from the wire harness 24. In addition, after the lower part 21b of the main body 21 is integrally crimped to the two holding pieces 23, and the female terminal body 21 is inserted into the female terminal insertion hole 17 from above, the terminal retaining piece of the female terminal 20 is secured. The tip of 22 crosses the retaining locking step portion 19 of the coupler 14 and locks on the locking step portion 19, and the female terminal 20 is firmly attached to the coupler 14 so as not to come off from the coupler 14.

Then, the coupler 14 is connected to the coupler fitting portion 7 of the terminal holder 1.
, The holding piece 23 of the female terminal 20 is attached to the terminal plate 10.
The terminals 10 and 20 are elastically and closely fitted to each other, and the terminals 10 and 20 are electrically and stably connected.

Eight coupler fittings provided in the terminal holder 1 are provided by selectively connecting the wire core wires 26 of the required wires 25 through the female terminals 20 to the nine female terminal insertion holes 17 provided in the coupler 14. If the required coupler 14 is fitted in any one of the coupling portions 7, the wires 25 connected to different couplers 14 are electrically connected to each other via the same terminal plate 10 that crosses the coupler fitting portion 7 at a right angle. Can be connected to each other.

Therefore, the coupler connecting device can connect each electric component of the motorcycle to the power source through various switches.

Further, in the above embodiment, each terminal plate 10 is integrally embedded in the substrate 2 in a predetermined positional relationship in a state of being formed with a uniform width along the longitudinal direction thereof. The fitting portion of the terminal plate 10 to be fitted firmly holds the partition wall 6 of the substrate 2 without causing a large elastic deformation, and the coupler 14 is connected to the coupler fitting portion 7.
The terminal plate (10) can sufficiently withstand the force applied when it is fitted in, and the fitting and removal of the coupler (14) can be performed easily and reliably.

Furthermore, since it is sufficient to embed each of the terminal plates 10 integrally during injection molding of the terminal holder 1 and cut off both end portions 11a of the brass plate 11 after molding, it is troublesome to mount each terminal plate 10 on the terminal holder 1. The productivity is good.
