Abstract

A small rectangular-plate type filtering socket comprises a casing body, an insulator, a guide sleeve, a guide pin, a round nut provided with a groove, a filtering board and a crowned insertion hole, wherein the plastic compression is realized between the casing body and the insulator in an embedded manner; the guide sleeve and the guide pin are installed inside the casing body through the round nut provided with the groove; and the filtering board, the crowned insertion hole and the casing body are welded with one another. The utility model has the advantages that the metal casing body realizes the shielding performance; the integrated structure is realized through the embedded plastic-compression casing body and the filtering board with irregular property; the filtering board, the crowned insertion hole and the casing body can be welded at one time through a backflow welder with convenient and reliable assembly; the damage to the filtering board caused by excessive pressure of a spring connecting structure is avoided; the space for installing a grounding spring is saved; and the small rectangular-plate type filtering socket realizes the connection through the flexible contact between a rigid cylindrical insertion pin and the elastic crowned insertion hole. The small rectangular-plate type filtering socket has the characteristics of reliable contact, low contact resistance, vibration resistance, shock resistance and the like.

Description

A kind of little rectangular plate type filtering socket

Technical field

The utility model relates to the electrical connection field, particularly a kind of little rectangular plate type filtering socket.

Background technology

Related product is the printed wiring board socket at present, and volume is little, and no housing does not have filter function, simultaneously the contact performance instability.

The utility model content

The purpose of this utility model is to realize filter function, and the spy provides a kind of little rectangular plate type filtering socket.

The utility model provides a kind of little rectangular plate type filtering socket, it is characterized in that: described little rectangular plate type filtering socket comprises housing 1, insulator 2, guide pin bushing 3, pilot pin 4, grooved round nut 5, filter band 6, hat spring socket 7;

Wherein: inlay plastic compression between housing 1 and the insulator 2, guide pin bushing 3 is installed in the insulator 2, and pilot pin 4 is installed in housing 1 inside by grooved round nut 5, and ripple plate plate 6, hat spring socket 7 and housing 1 are welded to connect.

Described ripple plate plate 6, hat spring socket 7 and housing 1 are welded to connect back casting glue embedding.

Advantage of the present utility model:

Metal shell has been realized shielding properties, in order to guarantee the original product size and to achieve a butt joint, the plastic compression housing is inlayed in employing, different in nature filter band is realized overall structure, ripple plate plate once can weld by reflow machine and finish with hat spring socket, housing, convenient and reliable assembly has been avoided spring access node structure because pressure is excessive filter band has been caused damage, and saves the space that grounding reed is installed, once welding can realize, can not produce the product damage of weld pads for the first time because of secondary welding.

This little rectangular plate type filtering socket is to realize being connected with Elastic Contact between the flexible hat spring socket by the cylinder type contact pin of rigidity.Have reliable, the characteristics such as contact resistance is low, vibration resistance, shock resistance of contact.
