Description

[Detailed Description of the Invention] The present invention relates to a structure for temporarily fixing lead wires using a printed wiring board.

In the conventional temporary fixing of lead wires, as shown in FIG.
A lead wire 5, one end of which was soldered to the back surface of the printed wiring board 4, was temporarily fixed by a clamp wire 6 inserted into the small hole 4a. However, this method requires a special clamp wire 6, and also requires insertion and knotting of the clamp wire 6.

As another example, as shown in FIG. 2, a T-shaped hole 4b is cut into the printed wiring board 4, and the inner part of the hole 4b is enlarged between the entrances.
There was also a method for temporarily fixing the lead wire 5 by pushing in the lead wire 5, but in this case, there was a drawback that the lead wire 5 easily came off from the hole 4b.

This invention was made in view of these points,
The purpose is to close the hole shown in Figure 2 with a retaining body for fixing the printed wiring board, so that no special clamp wire is required and the lead wire can be securely temporarily secured. An object of the present invention is to provide a temporary fixing structure for lead wires.

Examples of the present invention will be described below. Third
As shown in the figure, a T-shaped hole 4b similar to the conventional one is cut into the printed wiring board 4, and the printed wiring board 4 is inserted into the board 1 at the entrance.
A notch 4c is formed in which the elastic locking body 7 locks in order to position and fix the locking member 7 relative to the housing. In this case, the lateral length of the notch 4c corresponds to the length of the locking body 7. The above-described holes 4b and notches 4c are formed in the printed wiring board 4 on at least two parallel sides, and the locking bodies 7 are also formed in at least two corresponding positions. Note that the hole 7a formed in the upright portion of the locking body 7 is used for punching out the pawl 7b of the locking body 7.

In the above, if the lead wire 5 is inserted in advance into the hole 4b through the notch 4c of the printed wiring board 4, and then the notch 4c is engaged with the locking body 7, as shown in FIG. As shown, the entrance of the hole 4b is closed by the locking body 7, and the lead wire 5 cannot be removed.

Note that a plurality of bosses 8 (not shown) as spacers are protruded from the board 1, and the printed wiring board 4 is held against the bosses 8 by the locking body 7 while the printed wiring board 4 is held against the bosses 8 by the locking body 7. It can be attached to 1. Furthermore, as described above, at least two parallel sides of the printed wiring board 4 are similarly locked by the locking bodies 7, so that the locking bodies 7 are located in a direction perpendicular to the two parallel sides. It works as a stopper to restrict movement, and in the direction parallel to the two sides, the locking body 7 bites into the notch 4c, so movement is similarly restricted, and eventually the printed wiring board 4 can move in either direction. Movement will also be regulated.

In the above, the notches 4c were provided in the printed wiring board 4 in order to lock the locking body 7 at only two positions, but the right side (usually four sides) of the printed wiring board is supported by the locking body. In this case, the notch 4c is not necessary.

As described above, according to the present invention, it is only necessary to close the hole for inserting the lead wire with the locking body, so that the hole for inserting the lead wire can be closed when the printed wiring board is attached to the board, and the special clamp wire can be closed. This method has the advantage of eliminating the need for lead wires and ensuring that the lead wires are temporarily secured.
