Detailed Description
The present invention will be further illustrated with reference to the following specific examples.
Referring to fig. 1-6, a double-locking electrical connector comprises a socket 1 and a plug 2, wherein the socket 1 comprises a socket shell 11, the plug 2 comprises a plug locking sleeve 21 and a plug clamping cap 26, the socket 1 is in threaded connection with the plug clamping cap 26, an external thread 112 is arranged at one end of the socket shell 11, an internal thread 263 is arranged at one end of the plug clamping cap 26, and the external thread 112 is matched with the internal thread 263.
The plug lock sleeve 21 is movably sleeved outside the plug clamping cap 26, a clamping piece on the side wall of the plug clamping cap 26 in the embodiment is a clamping cap steel ball 23, two stepped holes 261 are symmetrically formed in the side wall of the plug clamping cap 26, a clamping cap steel ball 23 is arranged in each stepped hole 261, and the diameter of each stepped hole 261 is smaller than that of the clamping cap steel ball 23. The middle portion of the outer wall of the socket housing 11 is provided with a semi-spherical groove 111 of one turn, and the semi-spherical groove 111 is matched with the position of the stepped hole 261. The stepped hole 261 cooperates with the hemispherical groove 111 of the socket housing 11 to achieve the locking function of the snap cap steel ball 23.
The lateral wall of one end of the plug locking sleeve 21 is provided with a threaded hole 211, the lateral wall of one end of the plug clamping cap 26 is provided with a seven-shaped groove 262, the threaded hole 211 is internally provided with a set screw 25, and the set screw 25 can move in the seven-shaped groove 262. The axial limiting function of the plug locking sleeve 21 can be realized by the cooperation of the seven-shaped groove 262 and the set screw 25.
The inner wall of the other end of the plug locking sleeve 21 is provided with a step groove 212, the outer wall of one end of the plug clamping cap 26 is provided with a circle of locking sleeve retainer 22, and the locking sleeve retainer 22 is matched with the step groove 212 to limit the axial displacement of the plug locking sleeve 21.
The relative displacement of the plug locking sleeve 21 on the plug clamping cap 26 in the plug 2 is axially limited at one end by the locking sleeve retainer 22 and the stepped groove 212, and axially limited at the other end by the matching use of the threaded hole 211, the set screw 25 and the seven-shaped groove 262.
When the socket 1 and the plug clamping cap 26 are locked by screw threads, the plug locking sleeve 21 is moved to enable the clamping cap steel ball 23 to press the side wall of the socket 1 so as to realize the clamping of the socket 1 and the plug 2. A spring 24 is arranged in a cavity formed between the inner wall of the plug locking sleeve 21 and the outer wall of the plug clamping cap 26. When the socket 1 and the plug clamping cap 26 are screwed and locked, the set screw 25 is tightened at the same time, and the spring 24 is in a compressed state, so that the stability of the socket 1 and the plug clamping cap 26 can be further ensured.
The cap clamping steel ball 23 is fixed and limited with the inner wall of the plug locking sleeve 21 through the hemispherical groove 111 of the socket shell 11, so that the steel ball locking function is realized. In addition, the external thread 112 of the socket housing 11 is screwed with the internal thread 263 of the plug cap 26 to realize a thread locking function.
The working principle is as follows:
when in use, the plug locking sleeve 21 is pulled backwards and rotated anticlockwise for a certain angle until the set screw 25 is hung on the seven-shaped groove 262 of the plug clamping cap 26; the inner wall of one port of the plug locking sleeve 21 is provided with a step groove 212, and a certain gap is formed between the step groove 212 and the outer wall of the plug clamping cap 26, so that the plug locking sleeve 21 is pulled backwards, a space for radial displacement of the clamping cap steel ball 23 can be arranged at the step hole 261, the socket 1 is inserted into the plug clamping cap 26, and the clamping cap steel ball 23 arranged in the step hole 261 of the plug clamping cap 26 can move radially at the moment.
Then the plug clamping cap 26 with the internal thread 263 is in butt-joint and rotary joint with the socket shell 11 with the external thread until the clamping cap steel ball 23 falls into the hemispherical groove 111 of the socket shell 11; finally, after the plug locking sleeve 21 is rotated clockwise by a certain angle, the plug locking sleeve 21 axially moves under the action of the resilience force of the spring 24 until the bottom of the stepped groove 212 is contacted with the locking sleeve retainer ring 22, and at the moment, the cap clamping steel ball 23 is limited by the inner wall of the plug locking sleeve 21 and cannot radially move; the set screw 25 is tightened so that the plug locking sleeve 21 is fixed to the plug locking cap 26. The above operation finally realizes the function of double locking of the socket housing 11 and the plug snap cap 26.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
