Plug shell assembly and sub board plug

Abstract

The invention discloses a plug shell assembly and a sub board plug. The plug shell assembly comprises a floating shell and an insulator mounted in the floating shell, wherein the insulator is provided with an elastic push rod; the elastic push rod comprises a rod body which extends from back to front in a suspension manner; a shell stop structure is arranged in the floating shell; a rod body stop structure, which is matched with the shell stop structure in a stopping manner and used for preventing the floating shell from moving forwards relative to the insulator, is arranged on the rod body; a plug contact part and a force-bearing part are arranged on the front side of the rod body stop structure on the rod body, wherein after the force-bearing part is inserted with a socket contact part in a proper position, the force-bearing part is jacked by a socket shell to enable the elastic push rod to be elastically deformed so as to remove a stop matching relation between the elastic push rod and the floating shell; and an accommodating space which is used for allowing the elastic push rod to elastically recover is also formed in the floating shell after the elastic push rod floats forwardly relative to the plug insulator when the stop matching relation between the elastic push rod and the floating shell is removed. The elastic push rod of the sub board plug is high in rebound elasticity, and stable and reliable in use.

Description

Technical field [0001] The invention relates to a plug housing assembly and a sub-board plug using the plug housing assembly. Background technique [0002] The circuit printed board is an important electronic component in the communication equipment cabinet, which is divided into a longitudinally placed backplane and a horizontally placed daughter board. During device operation, communication data needs to be transmitted between the backplane and the daughter board. In the traditional way, most of the optical jumpers are used to realize the intermediate transfer between the backplane and the daughter board, but a large number of optical jumpers take up space, the wiring is messy, and the later maintenance is very inconvenient. In response to this problem, inter-board optical fiber connectors came into being. Through the inter-board optical fiber connectors, the optical fiber jumper-free connection between the printed board and the printed board can be realized. It can be directl...

Problems solved by technology

[0005] However, when the floating shell of the sub-board plug and the shell of the plug part are relatively floating, the elastic push rod is always in a state of bending under force, and deformed under force for a long time, which is likely to cause elastic fatigue, which is not conducive to the rebound of the elastic push rod , especially when the external environment temperature has a large temperature difference change, the elastic push rod is easy to lose the resilience performance, so that the effective stop between the insulator and the floating shell cannot be guaranteed, resulting in the sub-board and the back board being mated in place At this time, the plug and socket may not be mated in place, seriously affecting the docking of the connector

In addition, the elastic push rod and the housing of the plug part are two parts. When the two parts are fixedly installed together, the consistency is poor, and the force of the two elastic push rods is not synchronized and uneven; and the two elastic The push rod is set on the same side of the plug part shell, so that the plug part shell is unevenly stressed, easy to tilt, and even causes the elastic push rod to fail before locking
