Description

[Detailed Description of the Invention] The present invention relates to a connector for connecting a printed circuit board, which is connected to a printed circuit board in a controller of an electric carpet, for example, and is detachably connected to a junction box of a cord extending from the electric carpet. .

This type of connector consists of a plurality of plugs held side by side at intervals in a holder, and a plurality of connection conductors extending from the rear ends of the plurality of plugs and respectively inserted into and connected to a plurality of connection holes on a printed circuit board. It consists of. In the prior art, this connecting conductor consists of a cable connected to a plug;
Since the distance between the connector and the printed circuit board usually needs to be small, inserting the cable into the connection hole is difficult, and when the cable conductor is soldered to the printed circuit board after insertion, the elasticity of the cable It is easy to pull out of the connection hole, resulting in uneven soldering.Furthermore, since the spacing between the connection holes is usually smaller than the spacing between the plugs, the outermost cable in particular needs to be bent inward, which can damage the holder and cable. There was a drawback.

SUMMARY OF THE INVENTION An object of the present invention is to provide a connector for connecting a printed circuit board, which allows connection to a connection hole of a printed circuit board to be performed with an extremely easy operation.

Embodiments of the present invention will be described in detail with reference to the drawings. FIGS. 1 and 2 show a connector 1 according to the present invention.
0 is shown connected to a printed circuit board 12, and the connector 10 is a plastic molded holder 1.
4 and a plurality of plugs 16 (see FIG. 3) inserted and held in parallel at intervals in the holder 14, extending from the rear ends of these plugs and inserted into the plurality of connection holes 12a of the printed circuit board 12, respectively. It consists of a plurality of connection conductors 18 that are connected together. In addition, in the illustrated embodiment, the connection hole 12a
are arranged in a staggered manner as shown in FIG. 1, but they may also be arranged on the same line.

As shown in FIGS. 4A and 4B, the plug 16 is formed by bending a conductive plate into a cylindrical shape with a rounded tip, and the connecting conductor 18 is integrated with the conductive plate of the plug. Moreover, these connection conductors 18 are
As shown in FIGS. 1 and 5, a printed circuit board 1
The connection holes 12a of the second connection hole 12a have claws 18a that extend toward the connection holes 12a and are shifted in the thickness direction of the printed circuit board 12 so as to be inserted alternately from the front and back sides in opposite directions. Therefore, every other connecting conductor 18A is on one surface and its claws 12a are in the same direction, and every other connecting conductor 18B is on another surface and its claws 12a are in the same direction. The claws of every other connecting conductor are in the opposite direction.

As shown in FIG. 5A, the connector 10 described above is constructed by inserting a round bar or the like between opposing connecting conductors 18A and 18B, pushing these connecting conductors apart, and inserting a printed circuit board 12 between them. When the round bar is then pulled out, the connecting conductors 18A and 18B clamp the printed circuit board 12, and their claws 18a are inserted into the connecting holes 12a (see FIGS. 2 and 5B). Therefore, the fifth
As shown in Figure C, attach the claw 18a to the printed circuit board 12.
Connector 10 is connected to printed circuit board 12 by solder 20 . Furthermore, Figures 2 and 5
As shown in FIG. B, when the lengths of the connection conductors 18A and 18B are different, the connection hole 12
This is preferable because the distance a can be made even smaller. Further, as shown in FIG. 1, the outer connecting conductor 18 is preferably bent in advance to fit the connecting hole 12a.

6A and 6B show another embodiment of the invention in which every other plug 16 is staggered in the thickness direction of the printed circuit board 12, in which case the connecting conductor 1
As shown in FIG. 4B, the plugs 8 can be shifted alternately without being bent, and the spacing between the plugs 16 can be reduced, so the size can be further reduced, and there is no need to bend the outer connecting conductor inward. It disappears.

According to the present invention, as described above, the connecting conductor that connects the plug and the printed circuit board is made of conductive plates that are integrated with the plug, and that are alternately shifted in the thickness direction of the printed circuit board and have claws at the tips. Therefore, it can be easily inserted into the connection hole of the printed circuit board, and since the connection conductor is rigid, it will not come out once it is inserted into the connection hole, so the connection can be made well. Unlike connections, short circuits between poles due to poor connections and damage to the holder and cable due to bending do not occur.
