Description

[Detailed description of the invention] The present invention is a lead wire extraction mechanism in which appropriate electrical parts are housed in a case, and lead wires connected to these parts are led out from a hole provided in the case wall. Regarding the improvement of a mechanism for fixing the lead wire to the case so that it does not come off from the case, the purpose is to securely fix the lead wire to the inner surface of the case facing the hole through a simple structure and operation. It is something.

First, details of the embodiment will be described with reference to the drawings.

As an example, a structure for fixing lead wires led out from a coil bobbin case that is adhesively used in a motor or the like will be described.

1 is a donut-shaped case that can be opened and closed with inward raised edges 2 on the left and right side edges, and a bobbin 4 on which a coil 3 is wound is fitted and held inside the case 1; One end of each of the filaments 5a, 5b constituting the lead wire 5 is connected, and the filaments 5a, 5b are led out from holes provided in the wall of the case 1 as described below.

That is, two holes 6 and 7 are provided adjacent to each other on the left and right, and the lead wire portion facing the inner wall of the hole is connected to the lead-out side of one filament 5a from the other filament 5b as shown in FIGS. 4 and 5. A deformable ring member 8 such as an elastic tube (corresponding to a hollow member having a hole at the center in the claims) is tightly fitted in parallel with the lead-out side of the ring member 8, and the outer surface of the ring member 8 is The ring member 8 is brought into contact with the inner surface of the partition wall 9 naturally formed between the left and right holes 6 and 7 so that the left and right holes 6 and 7 provided in the wall surface communicate with each other, and one The filament 5a is inserted into the hole 6 on the outlet side, and the other filament 5b is inserted into the hole 7 on the other side.

In this example, the case wall portion having the holes 6 and 7 is made to protrude outward from the other case portions, and a recess 10 is formed inside the case wall portion, and the ring member 8 and this ring in this recess are The bent wire portions are held at both ends of the member to prevent the lead wire from moving in the inner circumferential direction of the case.

As described above, according to the present invention, the lead wire led out from inside the case is arranged such that one wire and the other wire constituting the lead wire are placed in the center with their lead-out sides crossed. A hollow member having a hole is inserted in parallel in a tight fit, and the outer surface of this hollow member is passed through the hole in the hollow member to the inner surface of the partition wall between the left and right holes provided in the case, so that the left and right holes communicate with each other. One of the filaments passed through the hollow member is inserted into the hole on the outlet side, and the other filament is inserted into the other hole, so that the two filaments are connected at both ends with the hollow member as the contact point. The lead wire is pulled out from the surface in a bent shape parallel to the end surface, making it possible to securely secure the lead wire to the inner surface of the case without forcing it to come out.It has practical effects such as its structure and easy fixing operation. is big.
