Embodiment Construction

[0018] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0019] see figure 1 , Figure 4 , Figure 5 and Figure 6 , A board-to-board connector composed of plugs and sockets. The inter-board connector includes a plug 3 affixed to the sub-board 1 , and a socket affixed to the backplane 2 and mated with the aforesaid plug. With the front end of the plug as the plug-in end, the plug 3 includes an outer shell 302 fixed on the sub-board 1 through four locking studs 301, installed in the outer shell through the cooperation of the key and the keyway, and floats with the outer shell The assembled inner casing 303 is provided with a first contact 501 inside the inner casing 303 . The socket includes a socket housing 401 fixed on the backplane 2 through two locking nuts 402 , and a second contact 502 is arranged in the socket housing 401 . This embodiment is suitable...

Abstract

The invention discloses a plug for a board-to-board connector, which is characterized in that a spring floating structure is arranged between an outer shell and an inner shell of the plug, and the spring floating structure comprises a floating spring which is limited between the outer shell and the inner shell through a locking structure when the outer shell and the inner shell are assembled and provides an elastic force to enable the inner shell of the plug and a shell of the socket to be in floating butt joint when the plug is inserted into the socket. According to the plug provided by the invention, the spring floating structure is arranged between the inner shell and the outer shell, and the floating butt joint of the inner shell of the plug and the inner shell of the socket during butt joint of the plug and the socket is achieved. Compared with floating butt joint achieved through the existing mechanical cantilever structure, the service life of the board-to-board connector can beprolonged, and the connection reliability can be improved.

Description

technical field [0001] The invention belongs to the technical field of board-to-board connectors, and in particular relates to a plug for board-to-board connectors. Background technique [0002] In optical communication systems, printed boards are usually used as carriers to integrate optical and electronic components to realize the transmission of optical signals. The printed board is divided into a vertically placed backplane and a horizontally placed subboard. To realize signal transmission, the connection between the backplane and the subboard needs to be realized. The traditional connection method is to use optical jumpers to realize the intermediate transfer between the backplane and the sub-board, but the arrangement of a large number of optical jumpers consumes space, and the installation and wiring are messy, which is not conducive to later maintenance. In response to this problem, the inter-board optical fiber connector came into being. The "hard" connection betwe...
