Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 4, the present invention provides a technical solution:

the utility model provides a connector with locking take off and prevent mistake and insert function, including plug 2 and socket 1, socket 1 is last the symmetry and has seted up threaded hole 4, threaded connection has connecting rod 7 in the threaded hole 4, spring 5 has been cup jointed on the connecting rod 7, and connecting rod 7 passes connecting hole 6 and pegs graft on fastener, connecting hole 6 is seted up on fastener and fastener is solid fixed ring 3, gu fixed ring 3 cup joints on socket 1, connect on socket 1 through connecting rod 7, and gu fixed ring 3 is last to be seted up first cooperation groove 16 and second cooperation groove 15 and the width of first cooperation groove 16 is less than the width of second cooperation groove 15, and first cooperation groove 16 cooperatees with first locating piece 8, second cooperation groove 15 cooperatees with second locating piece 18 and all seted up fixed orifices 17 in first cooperation groove 16 and the second cooperation groove 15.

Spring 5 is between the conical head on fastener and connecting rod 7, the both sides welded fastening of plug 2 has the locating piece, the locating piece divide into first locating piece 8 and second locating piece 18, the width of first locating piece 8 is less than the width of second locating piece 18, and jack 14 has all been seted up on first locating piece 8 and the second locating piece 18, peg graft in jack 14 has locking device, and two locating pieces all peg graft on fastener and locking device be arc 9 and arc 9 peg graft in the fixed orifices 17 in the cooperation groove under the state that plug 2 and socket 1 are connected, and the smooth no burr of upper surface of arc 9.

The lower extreme welded fastening of arc piece 9 has guide bar 10, has cup jointed spring 5 on the guide bar 10, and spring 5 welds respectively in the bottom of spliced eye 14 and the lower extreme of arc piece 9, and the rear end of arc piece 9 is fixed and is provided with movable block 11 and be welded connection between the arc piece 9, and the one end welded fastening of movable block 11 has elastic sheet 12, and elastic sheet 12 pegs graft in removing the hole 13, and removal hole 13 is seted up on the locating piece.

The working principle is as follows: when the utility model works, the first positioning block 8 and the second positioning block 18 on the plug 2 are respectively inserted into the socket 1 corresponding to the first matching groove 15 and the second matching groove 16 on the fixing ring, so that the pin on the plug 2 can not be inserted into the jack, and the positioning blocks are set to different sizes, namely, the positioning blocks with the same size are prevented from being inserted into the matching holes with the same size, so that the pin can be inserted into the jack, when the positioning blocks and the matching grooves are different in size, the fixing ring 3 is obstructed by the positioning blocks and can not play a role of fastening when the fixing ring 3 is pulled towards the plug 2, so that the plug 2 can be known to be inserted wrongly, thereby the misplugging is avoided, then when the plug 2 and the socket 1 are inserted, the fixing ring 3 is pulled, so that the fixing ring 3 is sleeved at the connection part of the plug 2 and the socket 1, the mating groove presses the arc-shaped block 9, so that it retracts into the insertion hole 14, so that the positioning block enters into the mating groove, then the arc-shaped block 9 is sprung up into the fixing hole 17 under the action of the spring 5, at the moment, the fixing ring 3 plays a role of fastening, because the arc-shaped block 9 is clamped in the fixing hole 17, therefore, the plug 2 and the socket 1 can not be separated, the anti-loose function is achieved, when the plug needs to be detached, the elastic thin plate 12 is pushed downwards to enable the arc-shaped blocks 9 to exit from the fixing holes 17, then the fixing ring 3 is moved away from the plug 2 by the spring 5, at which time the plug 2 can be pulled out and separated, when the arc-shaped blocks 9 are mounted, when the elastic sheet 12 reaches the position of the moving hole 13, the elastic sheet 12 can be freely moved in the moving hole 13, and the elastic sheet is ejected to the outer end of the positioning block under the action of elasticity and clamped in the moving hole 13 to realize the installation of the arc-shaped block 9.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
