Detailed ways

Embodiment 1 of an electrical connector assembly, as shown in FIGS. 1-4 , consists of a plug 1 and a socket 2 .

The plug 1 has a plug housing 1-1, and the coaxial rotation sleeve on the plug housing 1-1 is provided with a connecting nut 1-2, and the connecting nut 1-2 is assembled to the plug housing 1 through a retaining spring to prevent detachment in the axial direction -1, the plug end of the plug housing 1-1 has an inversion edge 1-3 and is provided with an opening 1-4, the opening 1-4 is a through groove through the inner and outer walls of the plug housing and the opening 1-4 The notch is located at the front end of the plug housing 1-1, and the front end of the opening (that is, the notch) is provided with a flaring structure, which can "catch" the socket shell from a wider range when the plug is plugged into the socket The protrusion on the body, so as to realize the positioning and matching with the socket, the opening 1-4 and the inner turning edge make the insertion end of the plug housing form a jack section, which can be connected with the socket shell through the inner turning edge when in use Body electrical contact, the front end of the jack section, that is, the insertion end of the plug housing, is provided with a flared structure for the insertion of the socket housing, and the flared structure at the insertion end of the plug housing is used to smoothly introduce the socket housing into the plug The housing realizes the positioning fit between the two. The plug housing compensates for the radial deformation caused by the insertion and extraction of the socket housing through the expansion and contraction at its opening. At the same time, due to the inversion along the With the existence of 1-3, when the plug-in end of the plug housing 1-1 is used as a jack, it is not necessary to perform an extrusion closing process on the plug-in end of the plug housing, thereby avoiding the problems caused by the extrusion closing process. The dimensional error ensures the contact performance of the jack section.

The socket 2 has a socket housing 2-1, and the plug-in end of the socket housing 2-1 has an external thread segment 2-2 corresponding to the connecting nut on the plug housing and an opening on the plug housing 2-1. Corresponding to the protrusion 2 - 3 , the protrusion 2 - 3 is provided on the outer peripheral surface of the plug-in end of the socket housing 2 .

When the plug and the socket are mated, the plug-in end of the socket housing is inserted into the socket section of the plug housing and is electrically connected with the plug housing. At the same time, the protrusion on the socket housing snaps into the plug housing. The anti-rotation structure is formed in the opening of the socket, so as to realize the anti-rotation fit between the plug housing and the socket housing. In use, as long as the socket is fixedly assembled on the corresponding installation panel, the plug and socket will After that, relative rotation can no longer occur, which effectively solves the problem that the existing plug, which is fixedly connected to the socket through the connecting nut, will rotate relative to the socket after being mated with the socket.

In other embodiments of the electrical connector assembly, the positions of the opening and the protrusion described in Embodiment 1 of the electrical connector assembly can also be interchanged, that is, the protrusion is provided on the outer wall of the plug housing, The opening is provided on the socket housing. In this case, the jack section needs to be provided on the socket housing. When plugging, the plug housing is inserted into the socket housing .
