JP2729489B2 - Solderless connector for printed circuit board and its mounting method - Google Patents

Description

The present invention relates to a technique for connecting a connector to a printed circuit board used in an electronic device, and more particularly to a technique suitable for connecting a connector by press-fitting the connector to the printed circuit board without soldering. The present invention relates to a solderless connector for a printed board.

[Conventional technology]

Japanese Patent Publication No. 60-16073 discloses a known example in which a conventional connector is press-fitted into a printed circuit board for connection. Conventionally, to press-fit a connector into a printed circuit board, a metal-comb-shaped press-fitting jig dedicated to the connector was mounted on a press, and pressure was applied to the bottom of the connector housing by press-fitting.

As shown in Fig. 4, the conventional dust cover is simply attached to the joint of the plug and receptacle to protect the contacts and prevent the adhesion of airborne dust to the connector contact surfaces. It was not designed to transmit pressure to the part.

[Problems to be solved by the invention]

In the above prior art, when press-fitting a connector to a printed circuit board, a metal comb-shaped press-fitting jig to be mounted on a press had to be prepared for each type of connector. The press-fitting jig is expensive because it is manufactured by precision processing of metal, and every time the type of connector changes in the press-fitting process, it takes time to replace the press-fitting jig mounted on the press.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a highly productive solderless connector for a printed circuit board and a method of mounting the same, which can be press-fitted by pressing a dustproof cover inserted into a connector housing when the connector is press-fitted into a printed circuit board. It is in.

[Means for solving the problem]

The object is to provide a connector housing made of an insulator,
The printed circuit board has a conductor connector contact, which is inserted so that a shoulder abuts on the bottom of the connector housing and one end of the connector is projected to the outside, and a dustproof cover mounted on the connector housing to protect the connector contact from dust. In a solderless connection connector which is press-fitted into a hole to be connected, this is achieved by a structure in which the side of the dustproof cover facing the connector contact is extended in a convex shape and abuts on the shoulder of the connector contact.

In addition, the above object is achieved with the dust-proof cover attached to the connector housing, and the convex extension of the dust-proof cover presses the shoulder of the connector contact to press-fit one end of the connector contact into a through hole of the printed circuit board. This is achieved by implementing

[Action]

When the upper end surface of the dustproof cover is pressed by a press, the pressure is applied from the convex extension of the dustproof cover to the connector contact shoulder that contacts the bottom of the connector housing, and the portion below the shoulder of the connector contact is fixed to the connector housing bottom. As one end of the connector contact protrudes outside, it is vertically pressed into the through hole of the printed circuit board without bending, and one end of the connector contact makes metal contact with the through hole without deformation or damage, and is securely connected without solder A highly productive solderless connector for printed boards can be provided.

(Example of the invention)

 An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows the structure of this embodiment.
Is pressed into the connector housing 4, the pressurizing portion 2 of the dustproof cover 1 contacts the shoulder 6 of the connector contact 5. The dustproof cover 1 is used to force the connector compliant part 7 into the through hole 8 of the printed circuit board 9 (7 to 12 kg).
/ Contact).

2 and 3 show a method of press-fitting the solderless connector for a printed board according to the present invention to a printed circuit board 9. The printed circuit board 9 is set on the receiving stand 10, and the upper portion of the dustproof cover 1 inserted into the connector housing 4 is pressed by the press 11, so that the shoulder portion of the connector contact 5 passes through the pressing portion 2 of the dustproof cover 1. The force is transmitted to 6,
The connector compliant portion 7 is press-fitted into the through hole 8 of the printed circuit board 9 and connected without metal by soldering.

According to the present embodiment, the dustproof cover can be directly pressed and mounted without using a dedicated press-fitting jig for each connector type, so that a jig setup operation is not required and productivity is improved. Further, since the mounting of the connector and the mounting of the dustproof cover are performed at the same time, and the connector is shipped as it is, the prevention of bending of the connector contact and the dustproof effect can be expected.

〔The invention's effect〕

According to the present invention, when the upper end face of the dust-proof cover is pressed with a press, the pressure is applied to the connector contact shoulder from the convex extension of the dust-proof cover, and one end of the connector contact is vertically pressed into the through hole without bending. In addition, one end of the connector contact is securely connected to the through hole without being deformed or damaged, so that there is an effect that mounting is facilitated and productivity is improved.
