PURPOSE:To reduce the number of parts and improve the work efficiency by mounting a connector provided with a support claw and a retaining pin, between a plurality of electronic circuit boards. CONSTITUTION:A connector A is equipped with contacts 11a and 11b, which are projecting in a skirt shape from both sides of the mold body 1, press projections 12 which are projecting in the direction where these contacts 11a and 11b abut on circuit patterns 21, and retaining pins 13, which are connected and fixed to the boards 2, being provided on the electronic circuit board 2 side of the body. Plural pieces of contacts 11 are provided at regular intervals at the body 1, and the right and left contacts 11a and 11b consist of one sheet of metallic plate, and they pierce the inside of the hold body. Moreover, the body 1 has a mold supports 15 arranged to support the body itself a certain distance apart from the board. On the contact side of a pin 13 is provided a support claw 14, which hooks on the board 2 as a measure to prevent slip out after connection so as to fix the connector A between the boards. In short, this is of such structure as to hold the board 2 between the support 15 and the support claw 14 of the pin 13.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector used for circuit-connecting an electronic circuit board.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, a connector of this type is connected to a cable 3 and a male connector 4 which is soldered to a electronic circuit board 2 fixed to a bracket 8 with a screw 7 by a contact lead 41. Female connector 31
Was connected to make a circuit connection.

Further, as shown in FIG. 6, the electronic circuit board 2
The male connector 5 and the female connector 6 soldered to the contact leads 51 and 61 are connected to each other, and then fixed to the bracket 8 with the screw 7 to perform the circuit connection.

[0004]

The circuit connection of the electronic circuit board by the conventional connector requires a male connector and a female connector connected to the cable in the connection between the cable and the connector as shown in FIG. Therefore, there is a drawback that the number of parts increases and the cost increases.

Further, in the connection between the male connector and the female connector as shown in FIG. 6, as a work operation during assembly, horizontal movement is required at the time of connecting the connector, and then the workability of attaching the electronic circuit board is extremely high. It had the drawback of being bad.

Therefore, an object of the present invention is to provide a connector which can reduce the number of parts and improve workability.

[0007]

In order to achieve the above object, a connector of the present invention is a connector mounted on an electronic circuit board on which a circuit pattern is printed. Of a metal plate having elasticity and elasticity and protruding in a V shape from both side surfaces of the mold body, a pressing protrusion protruding in a direction in which the contact abuts the circuit pattern, and an electronic circuit board of the mold body. And a holding pin provided on the side and fixedly connected to the electronic circuit board.

A supporting claw for hooking and fixing the electronic circuit board is provided on the contact side of the holding pin.

Also, the holding pin is inserted into a guide hole for fixing the mold body provided on the electronic circuit board.

[0010]

The present invention will be described below with reference to the drawings. 1 is a perspective view of a connector of the present invention, FIG. 2 is a sectional view taken along line XX in FIG. 1, FIG. 3 is a sectional view of the connector of the present invention mounted on an electronic circuit board, and FIG. 4 is another embodiment of the present invention. FIG. 6 is a cross-sectional view of the electronic circuit board mounted in a guide hole.

1 to 3, a connector A of the present invention comprises contacts 11a and 11b made of a metal having conductivity and elasticity and protruding in a V shape from both side surfaces of the mold body 1, and these contacts. 11a, 11b
And a holding pin 1 provided on the electronic circuit board 2 side of the mold body 1 and connected and fixed to the electronic circuit board 2.
3 and 3. A plurality of contacts 11 are provided on the mold body 1 at equal intervals, and the left and right contacts 11a and 11b are made of one metal plate and penetrate the inside of the hold body 1.

Further, the mold body 1 has an electronic circuit board 2
It has a mold support portion 15 for arranging the mold main body 1 at a predetermined interval. On the contact side of the holding pin 13, a support claw 14 that is hooked and fixed to the electronic circuit board 2 is provided as a measure for preventing disconnection after the connector A is connected between the electronic circuit boards 2 and 2. That is, the structure is such that the electronic circuit board 2 is held between the mold support portion 15 and the support claws 14 of the holding pin 13.

The electronic circuit board 2 shown in FIGS. 3 and 4 is fixed to the bracket 8 with screws 7 in advance. In FIG. 3, the connector A is inserted between the electronic circuit boards 2 and 2,
It is held by the mold support portion 15, the holding pin 13, and the support claw 14, and the contact 11 and the circuit pattern 21 are electrically connected.

Connector B of another embodiment of the present invention shown in FIG.
Is provided with a guide hole 22 in the electronic circuit board 2, and the holding pin 1
7 is inserted into the guide hole 22. Therefore, connector B
Is held by the mold supporting portion 19, the holding pin 17, and the holding claw 18, and electrically connects the contact 16 and the circuit pattern 23.

[0015]

As described above, according to the present invention, since the connector provided with the support claw and the holding pin is mounted between the plurality of electronic circuit boards, the connector can be attached and the circuit can be connected at the same time. It is possible to reduce the number of parts and improve workability.
