Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an improvement of a connector device comprising a board and a connector soldered to the board.

Conventionally, in this type of connector device, holes for inserting the terminal portion of the connector and holes for temporarily fixing the connector are formed in advance on the printed circuit board, and the connector is soldered to the printed circuit board as follows.
Insert the connector terminal legs of the connector into the terminal leg insertion holes of the printed circuit board, and insert mounting screws etc. into the mounting holes formed at the end of the insulator of the connector and the connector temporary fixing holes of the printed circuit board to attach the connector. Temporarily fix it to the printed circuit board. Temporarily fasten other connectors in the same way. With the required number of connectors temporarily attached in this manner, the connector terminal legs are immersed in, for example, a molten solder tank and soldered.

On the other hand, a bus bar is used to electrically connect a power source to the contacts of each connector, and the bus bar is attached to the connector or printed circuit board with screws or the like.

In this way, with conventional connector devices, in addition to temporarily fixing the connector to prevent it from coming loose during soldering, it is also necessary to attach a bus bar, which requires a lot of work and requires a lot of work to fit the connector mounting pitch. A bus bar must be used.

This idea was made in view of the above circumstances, and by integrally forming the connector fixing part and the signal supply part, there is no need for a special means for fixing the signal supply part, and the number of man-hours can be reduced. It is an object of the present invention to provide a connector device that can be reduced.

An embodiment of this invention will be described below with reference to FIGS. 1 and 2. This idea uses a conductive plate, for example, a copper alloy plate, to connect the connector stopper part 1 and the signal supply part 2.
An auxiliary member 3 is formed by integrating the two. The connector fastening part 1 of this auxiliary member 3 has a substantially semicircular plate-shaped part 4 at the tip, which is integrally connected to a band-shaped part 5, and an axial cut groove 6 is formed in this to form a hook. ing. On the other hand, the signal supply section 2 is integrally connected to the connector stopper section 1, bent into an L shape, and has a terminal leg insertion hole 10 formed in the bent surface so that it can be inserted into the contact terminal leg 9 of the connector 8. . Connector stopper 1 configured in this way
A plurality of signal supply sections 2 and 2 are formed in the same direction at predetermined intervals, and are connected to each other by a connection section 11. In this case, connector stopper 1
The mutual spacing is made to match the position where the connectors 8 are to be arranged, that is, the connector stopper insertion holes 13 formed in the substrate, for example, the printed circuit board 12. With this configuration, the auxiliary member 3 is inserted below the printed circuit board 12 with the contact terminal legs 9 of the connector 8 inserted into the terminal leg insertion holes (not obvious in the figure) formed on the printed circuit board 12. position, and insert the connector stopper insertion hole 1 of the printed circuit board 12 so that the tip of the connector stopper 1 is narrowed.
3 and into the connector insertion hole 14 of the connector 8, and the terminal leg insertion hole 10 of the signal supply section 2.
into the contact terminal leg 9. When the connector fixing part 1 protrudes from the top of the connector 8, the previously narrowed end returns to its original state, so that the connector 8 is temporarily fixed to the printed circuit board 12. In this state, the connector terminal legs are soldered.

Since the auxiliary member 3 in which the connector stopper part 1 and the signal supply part 2 are integrally formed is used in this way, the number of work steps during assembly is reduced compared to conventional devices. That is, in the conventional device, the means for attaching the connector and the bus bar for supplying power to the contacts were constructed separately, and these were attached separately. In contrast, in this invention, the contact terminal leg 9 is simply inserted into the terminal leg insertion hole of the signal supply section 2, and the connector stopper section 1 is inserted into the connector stopper insertion holes 13 and 14 of the printed circuit board 12 and the connector 8. good. Thereby, the connector 8 is temporarily fixed to the printed circuit board 12 by the connector fixing part 1. Further, the signal supply section 2 can be used as a power line or a ground line. Furthermore, it is practical because it is only necessary to consider the spacing between the connector stoppers 1 and the spacing between the connectors.

Note that this invention is not limited to the above-described embodiment, and the shape of the connector stopper 1 may be changed, for example. For example, the shape may be such that the head without a cut groove is inserted into the connector and then twisted so that it does not come out from the connector, or the shape may be such that a pin is inserted into the tip to prevent the head from coming off.

Further, in the above embodiment, the outermost contact terminal leg 9 of the contact terminal legs 9 of the connector is inserted into the contact terminal leg insertion hole 10 of the signal supply section 2, but this may also be used as the other contact terminal leg. good. In this case, for example, the extension length of the signal supply section 2 described above is increased toward the center of the contact terminal leg, and a terminal leg insertion hole is formed at this end.
A through hole may be formed between the terminal leg insertion hole and the connector stopper 1, and a contact terminal leg that does not need to be electrically connected to the signal supply section may protrude from the through hole.

Furthermore, the shape of the signal supply portion 2 may be bent so as to sandwich the contact terminal leg, for example, to increase the contact area with the contact terminal leg.
In addition, various modifications can be made without departing from the spirit and scope of this invention.
