Problems solved by technology

[0003] However, during insertion, in order to ensure that the barbed pin can be smoothly inserted into the designated position, the inner diameter of the upper assembly hole needs to be designed wider, so as to reserve a retractable space for the barbed shrapnel; however, after the insertion is completed, On the one hand, the reserved extra space will affect the assembly tightness of the PCB substrate and the connector, and dust will easily enter the assembly hole of the PCB substrate; on the other hand, it will reduce the assembly strength of the PCB substrate and the connector

Embodiment 1

[0030] Such as figure 1 As shown, in this embodiment, the pin 22 is a flat structure;

[0031] The contact piece 2 includes a board body 21 and a pin 22, the end of the board body 21 is provided with a pin 22; the pin 22 includes a main conductor 221 and an elastic contact piece 222, and one end of the main conductor is connected to Board body, the other end of the conductor is connected to the outer wall with an elastic contact piece; the outer tail end of the main conductor is covered with a metal block 3, and the metal block 3 and the elastic contact piece 222 are misplaced; the elastic contact piece can be inserted When it is adducted, inserted to a suitable position and then abducted and reset, the barbed structure can stop with the assembly hole of the PCB board; since the elastic contact piece 222 will shrink and deform when inserted, the dislocation distribution is used to avoid the blockage of the metal block 3 The elastic contact piece 222 moves; the section of the ...

Embodiment 2

[0044] Such as Figure 4 As shown, in this embodiment, the pin 22 is a cylindrical structure;

[0045] The contact piece 2 includes a board body 21 and a pin 22, the end of the board body 21 is provided with a pin 22; the pin 22 includes a main conductor 221 and an elastic contact piece 222, and one end of the main conductor is connected to Board body, the other end of the conductor is connected to the outer wall with an elastic contact piece; the outer tail end of the main conductor is covered with a metal block 3, and the metal block 3 and the elastic contact piece 222 are misplaced; the elastic contact piece can be inserted When it is adducted, inserted to a suitable position and then abducted and reset, the barbed structure can stop with the assembly hole of the PCB board; since the elastic contact piece 222 will shrink and deform when inserted, the dislocation distribution is used to avoid the blockage of the metal block 3 The elastic contact piece 222 moves; the section...

Abstract

The present invention provides a barb type signal contact piece of a pre-installed welding structure, the contact piece comprises a plate body and pins, and the pins are arranged at the end of the plate body. Each pin comprises a main conductor and an elastic contact piece, one end of the main conductor is connected with the plate body, and the other end of the main conductor is connected with theelastic contact piece arranged on the outer wall; the elastic contact piece is of a barb structure; and the outer tail end of the main conductor is sleeved with a metal block, and the metal block andthe elastic contact pieces are distributed in a staggered mode. According to the invention, the metal block is pre-installed on the contact piece, the metal block can be heated from the outside of the PCB substrate by using the PCB bonding pad during plug-in mounting, and the molten metal material can fill the surplus space between the PCB substrate and the pins, so that the welding assembly of the barb-shaped pins and the PCB substrate is realized, the assembly strength is improved, and the sealing assembly of the PCB substrate and the pins can also be realized; and external dust cannot enter the assembly hole of the PCB substrate.

Description

technical field [0001] The invention belongs to the technical field of connectors, in particular to a barb type signal contact piece pre-installed with a welding structure and a connector thereof. Background technique [0002] The barbed pin is a commonly used plug-in terminal in the connector. When in use, the barbed pin is crimped into the hole of the PCB board, the pin first passes through the upper assembly hole, and the barbed pin is Squeeze and shrink inward. When penetrating, the barbed pin enters the lower assembly hole, and the stopper at the bottom of the insulating base collides with the surface of the PCB substrate. At the same time, the barbed pin will reset and expand, and the barbed pin will The tail end of the barbed pin is in conflict with the inner upper surface of the lower assembly hole, so that the inner and outer limit stops can be realized; [0003] However, during insertion, in order to ensure that the barbed pin can be smoothly inserted into the des...
