Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a mounting structure for a housing of a connector configured on a backboard of a printed wiring board housing case made of a printed wiring board, and is particularly applicable to a press-fit type connector housing. The present invention relates to a mounting structure for mounting a connector housing using contact pins.

In recent years, electronic devices in general have been made smaller and lighter, and at the same time cost reductions have been carried out, and the ultimate goal of this cost reduction is to devise parts that can be assembled automatically. Therefore, a connector for plug-in connection of a backboard that accommodates a large number of printed wiring boards and connects them to circuits can also be press-fitted with a large number of single contact pins of the connector into the backboard using an automatic press-fitting device. It has been developed to construct a connector by using a press-fit type contact pin and attaching a connector housing to the contact pin inserted into the press-fit.

[Conventional technology]

FIG. 4 shows a conventional structure for attaching a connector to a backboard made of a printed wiring board, in which a is a side view of the mounted connector and b is a perspective view of the connector.

In the figure, the connector 2 on the backboard side to which the socket connector 4 of the printed wiring board 3 is connected by plug-in is a housing 21 made of a synthetic resin molded product.
A large number of contact pins 22 are implanted in the back board 1, and each contact pin 22 is inserted into a through hole in the back board 1.
are soldered to the circuit pattern of the backboard 1 by immersing them in molten solder in a molten solder bath.

[Problem that the invention attempts to solve]

Regarding the above conventional connector mounting structure,
Since the contact pin 22 is connected to the back board 1 by soldering, solder adheres to the entire soldered side of the contact pin 22, making it impossible to make a connector connection using this contact pin part. There is a problem. Furthermore,
Since it is difficult to assemble the connector 2 to the backboard 1 using automatic equipment, there are various problems such as poor work efficiency.

[Means for solving problems]

The present invention aims to solve the above-mentioned conventional problems and provide a housing mounting structure that allows contact pins to be press-fitted using an automatic press-fitting device and that simplifies housing mounting. The object of this invention is to provide a housing mounting structure in which a large number of contact pins press-fitted into a backboard are protruded from both sides of the backboard, and a housing is attached to the press-fit area of the contact pins of the backboard to form a connector on the backboard. A pair of backboard mounting brackets and a housing mounting bracket are provided to sandwich and attach both ends of the backboard in contact with each other from both sides. An anti-rotation pawl protruding toward the anti-rotation pawl insertion hole of the backboard mounting bracket is formed and inserted into the housing, which is attached to the backboard mounting bracket by the end face, and parallel to both sides of the notch in the center on the other end face. The claws of the clamped part having elasticity formed at both ends of the housing are inserted into the notches of the pair of housing mounting brackets, which are formed with fixed claws and are mounted facing each other. This is achieved by a housing mounting structure of the connector in which the connector is mounted by engaging with the housing fixing claw.

[Effect]

The housing mounting structure of the connector described above is simple and easy to assemble by sandwiching and mounting a backboard into which a large number of connector pins are press-fitted with a pair of backboard mounting brackets and a housing mounting bracket at both ends. The connector can be easily installed by simply positioning the housing between the opposing pair of housing mounting brackets, inserting the clamped parts at both ends into the notches, and engaging the claws with the housing fixing claws of the metal fittings. Configure.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the connector housing mounting structure according to the present invention will be described in detail by way of examples with reference to the drawings.

FIG. 1 is an exploded perspective view of an embodiment of the present invention. FIG. 3 is a partially sectional side view showing the assembled state according to the order of the exploded perspective view of FIG. 1. In the figure, a pair of backboard mounting brackets 5 (only one of which is shown in FIG. ), a back board 11 with mounting holes 111 at both ends and a number of through holes 112 provided at predetermined intervals in the middle, contact pins 6 made of a conductive material to be press-fitted into the through holes 112 of this back board 11, and a side surface. It consists of a pair of housing mounting fittings 7 that are U-shaped in appearance, and a housing 9 having pinched portions 91 formed at both ends.

Above, through hole 112 of backboard 11
A large number of contact pins 6 are inserted into the contact pins 6, and the elastic portion 61 in the middle thereof is press-fitted to hold the pins and connect them to a circuit. Therefore, the contact pin 6 protrudes from both sides of the through hole 112. The upper and lower ends of this backboard 11 are connected to the backboard mounting bracket 5.
Place the housing mounting brackets 7 on top of each other, and connect the housing mounting brackets 7 and the backboard 11 to the screw holes 5 of the backboard mounting brackets 5 using the tightening screws 8.
Attach by tightening the screws to 2. At this time, by inserting the anti-rotation claw 71 at the tip of the housing mounting bracket 7 into the hole 51 of the backboard mounting bracket 5, the bracket 7 can be prevented from rotating, and each screw 8 can be inserted.
Can be mounted in position. In the manner described above, the backboard 11 is clamped and mounted between the backboard mounting bracket 5 and the housing mounting bracket 7.

The housing mounting bracket 7 is as shown in the perspective view of FIG. That is, it has a U-shape in side view formed by bending a metal plate such as an iron plate, and has a fixing hole 71 on one end surface of both parallel end surfaces, and a fixing hole 71 at its tip that protrudes in the opposite direction in parallel with the U-shaped bottom surface. A rotation preventing claw 71 is formed by bending, and parallel housing fixing claws 73 are formed on both sides of a central notch 74 on the other end surface.

The housing 9, which is integrally molded into a box shape from a synthetic resin molded product, is mounted facing the housing 9 so that the contact pins 6 of the back board 11 are inserted into a large number of contact pin insertion holes provided at the bottom of the housing 9. The clamped portion 91 having elasticity is positioned between the pair of housing mounting fittings 7 and 7 and is formed on the outside of both ends in the longitudinal direction, and is pushed in the direction of the arrow. The held portion 91 has a slit formed in the center thereof, and can be elastically deformed to the left and right in the width direction of the housing. In addition, the tip has claws facing outward on both sides, so
When the clamped part is fitted into the notch 74 of the metal fitting 7 and pushed in, both sides are elastically deformed in the direction of the slit, and are restored with the tip claws passing through, and the claws engage with the housing fixing claws 73 on both sides. It won't come off.

Note that 3 in FIG. 1 is a printed wiring board having a socket connector 4 at the tip similar to that in FIG. 4.

In the above embodiment, the housing mounting fittings were made of iron plates, but other metal plates may be used, or they may be made of hard synthetic resin moldings.

[Effects of the invention] As is clear from the above explanation, according to the invention, the connector housing can be easily and reliably installed, and it is extremely effective for installing individual housings. It is possible to connect connectors on both sides of the backboard.
