Piercing connector and its contact parts

Abstract

The invention relates to a piercing type connector and a contact member component thereof. The piercing type connector comprises the contact member component which comprises piercing sheets and plug pins which are arranged in a front-and-back direction. The front ends of the plug pins are provided with a plug pin plugging structure. The rear ends of the piercing sheets are provided with a piercing sheet plugging structure which is contacted and plugged with the plug pin plugging structure. The piercing sheets are provided with the piercing sheet plugging structure, and the plug pins are provided with the plug pin plugging structure so that an electric connector formed by the piercing sheets and the plug pins can be realized by contacting and plugging of the piercing sheet plugging structure and the plug pin plugging structure in manufacturing of the connector, welding operation is not needed in the whole process and thus operation difficulty is reduced.

Description

technical field [0001] The invention relates to a piercing connector and a contact part thereof for electrical signal transmission. Background technique [0002] The piercing connector can realize fast on-site wiring of cables, so it is widely used. Existing puncture-type connectors such as the Chinese patent CN101542849A discloses "a clusterable circular pluggable connector for Ethernet". The plug-in connector is a puncture-type connector, including a connector housing And the contact parts placed in the connector housing, the connector housing includes the needle housing and the needle housing arranged front and rear, and a transfer printed board is arranged between the needle housing and the needle housing, The contact parts include the thorn piece placed on the front side of the transfer printed board and the pin placed on the rear side of the transfer printed board. The front end of the pin is welded to the transfer printed board, and the rear end of the thorn piece is...

AI Technical Summary

Problems solved by technology

The problem with the existing piercing connector is that the pins and stabs in the contact parts need to be welded to the transfer printed board separately. This welding process is complicated and requires high product assembly. When there are many points, the assembly efficiency is also very low; since the stab piece needs to be welded to the transfer printed board first, in order to ensure enough welding space and to prevent the influence of the welding temperature on the stab piece shell, before welding, do not To fix the thorn piece and the thorn piece housing, the thorn piece housing must be installed after welding the thorn piece, so that the gap between the thorn piece housing and the thorn piece and between the first and second thorn piece housings The sealing cannot be guaranteed, and water, dust and other sundries may enter through the gap between the first and second blade shells and cause pollution to the blades
