Bending needle core circular connector socket sealed by combined housing pouring glue

Abstract

The invention discloses a bending needle core circular connector socket sealed by combined housing pouring glue, which comprises a metal seat, a bending needle assembly, a plastic housing, a position guide pin, a glue body and a pressing ring, wherein the metal seat consists of a metal housing and a nut; the bending needle assembly consists of a bending needle core seat, a spring coil, a locating block and bending needles; the plastic housing consists of a housing part and a rear cover; the bending needle assembly is arranged in a cylinder of the metal housing; the outer side of the spring coil is sleeved with the pressing ring; the metal seat and the bending needle assembly are arranged in the housing part of the plastic housing; the position guide pin is meshed with a screw hole of the metal housing; and the glue body is injected in the plastic housing by an injector. The socket adopts a combined housing which is mounted on the outer side of the metal seat in a clamping manner, and a glue pouring technology is implemented between the housing and the bending needle assembly, so that accurate positions of the bending needle assembly and the housing are fixed, and the sealing property of a product is improved.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to a circular connector socket with a curved needle core sealed with glue on a combined shell. Background technique [0002] The looper core circular connector socket is mainly aimed at the occasion where the layout of the PCB board and the opening surface of the cabinet are perpendicular to each other, and is used to realize the electrical connection between the PCB board and the outside of the cabinet, the position accuracy of the looper core and the sealing with the shell There are high requirements for the degree of the looper core. In order to ensure the position accuracy of the looper core, the commonly used looper core socket in the prior art is made by pouring the bent parts of the tails of multiple looper cores into a plastic shell. The problem is that due to the difference in shrinkage between the metal material and the plastic, there is a gap between the...

[0002] The looper core circular connector socket is mainly aimed at the occasion where the layout of the PCB board and the opening surface of the cabinet are perpendicular to each other, and is used to realize the electrical connection between the PCB board and the outside of the cabinet, the position accuracy of the looper core and the sealing with the shell There are high requirements for the degree of the looper core. In order to ensure the position accuracy of the looper core, the commonly used looper core socket in the prior art is made by pouring the bent parts of the tails of multiple looper cores into a plastic shell. The problem is that due to the difference in shrinkage between the metal material and the plastic, there is a gap between the metal looper core and the plastic shell after casting, which cannot meet the waterproof performance index of the product, which leads to a decrease in the working reliability of the product and affects the The use of curved needle core circular connector socket in communication equipment
