Detailed Description

The technical solution of the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings,

referring to figures 1-7 of the drawings,

fig. 1 and fig. 2 show, anticreep connector specifically constitute by plug 1 and socket 2, socket 2 is fixed in equipment usually and is connected with the input, and plug 1 then is connected with the cable, and socket 2 is last to have joint portion 3 in this embodiment, and be located and be equipped with one-level auto-lock structure 31 in joint portion 3, second grade auto-lock structure 32 and tertiary auto-lock structure 33, in using, insert a section of thick bamboo 21 and stretch into plug 1, make boss 22 in proper order with one-level auto-lock structure 31, second grade auto-lock structure 32 and tertiary auto-lock structure 33 joint, through one-level auto-lock structure 31, mutually supporting of second grade auto-lock structure 32 and tertiary auto-lock structure 33, make firm degree promote greatly, can effectively prevent the mistake simultaneously and touch the unblock, the condition that makes socket 2 and plug 1 separate takes place.

More specifically, referring to the processes of fig. 7 to 3, the plug barrel 21 extends into the plug 1, the boss 22 on the plug barrel 21 first abuts against the first projection 313 arranged at the end of the first elastic element 311, and as the plug barrel 21 gradually increases, the pressure applied by the boss 22 to the first projection 313 gradually increases, so that the first elastic element 311 deforms, the first projection 313 is reset after being bounced, and the boss 22 enters the rear of the first projection 313 to form a snap connection, so that the plug 1 and the socket 2 are preliminarily fixed, which is a first-level self-locking;

along with the gradual progress of the insertion cylinder 21, the boss 22 abuts against the end part of the second elastic part 321, and pressure is gradually applied to enable the second elastic part 321 to reset after being deformed and tilted, so that the boss 22 enters the first clamping groove 322 to be secondarily fixed, and the secondary self-locking is realized;

finally, the clamping piece 331 is inserted into the clamping part 3, so that the second clamping groove 332 in the clamping piece 331 is clamped with the beam 323 in the second elastic piece 321, and after the clamping piece 331 and the second elastic piece 321 are completely clamped and fixed, the second protruding block 334 at the end part of the clamping piece 331 is clamped with the outermost end of the second elastic piece 321, which is three-level self-locking;

it can be seen from above-mentioned structure that, as long as tertiary auto-lock does not have the unblock, second grade auto-lock and one-level auto-lock then can't the unblock, even tertiary auto-lock is touched by the mistake and is opened, there are second grade auto-lock and one-level auto-lock as the locking guarantee in addition to avoid the condition emergence of socket 2 and plug 1 separation, provide the assurance to the equipment power supply.

To the above embodiment, anticreep connector unblock process as follows:

firstly, as shown in fig. 5, the clamping member 331 is pulled to move away from the clamping portion 3, so that the clamping member 331 deforms to allow the second projection 334 to cross the end portion of the second elastic member 321 and enter the first clamping groove 322, and primary unlocking is completed;

at this time, the clamping member 331 is still clamped with the elastic block, that is, the beam 323 is still placed in the second clamping slot 332, then pressure is applied to the second pressing portion 333, so that the clamping member 331 prizes the beam 323, that is, the second elastic member 321 is deformed and tilted, the boss 22 is separated from the first clamping slot 322, and meanwhile, the boss 22 can be separated from the second elastic member 321 by pulling the plug 1, as shown in fig. 6, secondary unlocking is completed;

however, the first bump 313 still abuts against the boss 22, so that the plug 1 and the socket 2 cannot be separated, and next, pressure is applied to the first pressing portion 312, so that one end of the first pressing portion 312 is tilted, that is, the first bump 313 is tilted, and the plug 1 is pulled at the same time, so that the plug 1 and the socket 2 can be separated, as shown in fig. 7, this is three-level unlocking.

Through the cooperation and the restriction of one-level self-locking structure 31, second grade self-locking structure 32 and tertiary self-locking structure 33, greatly increased the fastening degree of connector, promoted factor of safety to and the power consumption stability.

In the embodiment of the utility model, as shown in fig. 1 and 2, socket 2 includes barrel 11, and barrel 11 one end is equipped with the through-hole 111 that supplies the cable to pass, and the barrel 11 other end outside is equipped with casing 12, forms passageway 13 between casing 12 and the barrel 11 and supplies to insert a section of thick bamboo 21 and stretch into, and joint portion 3 establishes on barrel 11 and casing 12 surface to communicate with passageway 13, still be equipped with a plurality of strengthening ribs 14 between casing 12 and the barrel 11, barrel 11 is close to through-hole 111 one end joint and has back lid 4, still be equipped with sealed pad 5 between back lid 4 and the barrel 11, sealed pad 5 outside is equipped with the ripple arch.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
