Embodiment 1

[0021] see Figure 1-7 As shown, the electrical connector includes a socket 14, a plug 15 that is pluggably connected with the socket, and a protective cover 16; the lower surface of the protective cover has a protrusion 17, and when the plug is inserted into the socket, the protrusion can press the corresponding recess 13 on the plug . The protective cover 16 is turned over and connected on the socket by the protective cover shaft 19, and the torsion spring 12 that makes the protective cover turn downwards is sleeved on the protective cover shaft 19 in normal state.

[0022] see Figure 1-6 As shown, the rocker arm locking mechanism of the electrical connector includes two rocker arms 1 , two protective cover locking rollers 4 , two plug locking rollers 5 and a handle 3 . A protective cover locking roller 4 is respectively connected to both sides of the protective cover 16 . Two rocking arms 1 are on both sides of the protective cover, and are parallel to each other, and t...

Embodiment 2

[0029] Example 2 see Figure 5 , 7 , The electrical connector in 8, its plug 15 adopts existing plug (that is, the plug 15 removes the plug locking roller 5 in the embodiment 1). Other structures are with embodiment 1. The locking process when the plug is inserted into the socket:

[0030] Push the handle 3 to make the protective cover locking roller 4 on the protective cover fall into the protective cover positioning groove 7, insert the existing plug into the socket; continue to push the handle 3 to make the protective cover locking roller 4 on the protective cover Slip out from the shifting groove 6 of the protective cover, that is Figure 5 status shown. The protective cover is turned over freely again, and the protrusion 17 falls into the recess 13 on the plug, that is, Figure 7 As shown; push the handle 3 in the opposite direction, so that the first protective cover locking chute 8 on the rocker arm 1 is located above the position of the protective cover locking ro...

Abstract

The invention solves the problems that a traditional electrical connector has the defects of difficult assembly and disassembly of a plug, low vibration resistance of an electrical connector and unreliable seal contact between the plug and a socket in the processes of practical installation and operation and provides an electrical connector locking mechanism with convenient installation when the plug and the socket are plugged, reliable seal and simple structure. The electrical connector of the electrical connector locking mechanism comprises the socket, the plug and a protecting cover, wherein the plug is connected with the socket in a pluggable way; the protecting cover is turned over and connected to the socket; the lower surface of the protecting cover is provided with a protrusion; when the plug is plugged into the socket, the protrusion can compress a corresponding concave part on the plug; the side part of the protecting cover is provided with a protecting cover locking shaft; the electrical connector also comprises a rocking arm which is rotatably connected to the socket; the lower part of the rocking arm is provided with a first protecting cover locking slide groove; when the protrusion presses the concave part of the plug tightly, the protecting cover locking shaft is positioned in the first protecting cover locking slide groove and realizes the seal connection between the plug and the socket by the protecting cover.

Description

technical field [0001] The invention relates to a locking mechanism for an electrical connector, in particular to a rocker locking and positioning mechanism for an electrical connector. Background technique [0002] At present, the electrical connector of the same purpose on the diesel locomotive includes a socket, a plug that is pluggably connected with the socket, and a protective cover connected to the socket by flipping; the torsion spring is fixed on the socket, and its front end is pressed against the protective cover to protect The lower surface of the cover has protrusions, and when the plug is inserted into the socket, the protrusions can press against corresponding recesses on the plug. The sealing connection between the plug and the socket in the electrical connector is realized by pressing the parallel double torsion spring: the force is very large during installation and operation, and the part pressed on the protective cover is very easy to push the protective ...
