In addition, the rear side of the male head 2 is provided with a handle part 21, and at least one pull hole 211 is arranged on the handle part 21, which is used for the fingers to pass through; when it is needed to pull out the male head 2 from the female seat 1, the index finger is passed through the pull hole 211 of the handle part 21, and the thumb is pressed on the pressing part 62 at the rear end of the lock arm 6, so that the lock hook 61 at the front end of the lock arm 6 is separated from the lock groove 411 to achieve the purpose of unlocking, at this time, the handle part 21 is pulled out with force, and since the index finger is passed through the pull hole 211 of the handle part 21, it can better exert force to pull out the male head from the female seat, which is very convenient to operate.

[0026] The assembly structure of the female seat 1 and the lock frame 4 is described below.

[0027] The female seat 1 is formed with a connecting plate 11 outwardly protruding at the socket 10 and used for abutting with the shell, and the connecting plate 11 is provided with first through holes 111 on both sides; the lock frame 4 is provided with second through holes 42 on both sides, the lock frame 4 abuts with the connecting plate 11, and the second through holes 42 abut with the first through holes 111, and the first screw is screwed and fixed with the shell after passing through the second through holes 42 and the first through holes 111, so that the female seat 1 and the lock frame 4 are fixed on the shell and form a detachable assembly, and the assembly structure is simple. Since the lock frame 4 can be detached relative to the female seat 1, when the lock frame 4 is damaged in the use process, the lock frame 4 can be detached relative to the female seat 1, a new lock frame 4 can be replaced, and the lock frame 4 can continue to be used, which is energy-saving and environment-friendly, reduces the use cost, and prolongs the service life of the utility model.

[0028] The connecting frame 5 has the same shape as the connecting plate 11, and the lock block 41 protrudes outward from the upper end of the connecting plate 11, which can improve the appearance of the entire female seat.

[0029] The upper surface of the pressing portion 62 is provided with a plurality of anti-skid protrusions 621 distributed at intervals, and when the finger presses the pressing portion 62, the anti-skid protrusions 621 are contacted, so that a good anti-skid effect can be achieved, the pressing portion 62 can be pressed better, and then the lock hook 61 at the front end of the lock arm 6 is driven to be upwardly tilted, the lock hook 61 at the front end of the lock arm 6 is separated from the lock groove 411 to achieve the purpose of unlocking, and the operation is more convenient.

[0030] The assembly structure of the connecting frame 5 and the lock arm 6 is as follows:

[0031] The upper end of the connecting frame 5 is provided with a pivot seat 53, the pin shaft 51 is arranged in the pivot seat 53, the pin shaft 51 also passes through the shaft hole in the middle of the lock arm 6, the end of the pin shaft 51 protrudes outward from the outer side of the pivot seat 53, the end of the pin shaft 51 is provided with a clamping groove, a clamping spring 54 is clamped in the clamping groove, and the clamping spring 54 is attached to the outer side of the pivot seat 53 to limit the pin shaft 51 in the pivot seat 53, which has a simple assembly structure and is convenient to install; the torsional spring 52 is sleeved on the pin shaft 51 and arranged in the pivot seat 53, one end of the torsional spring 52 abuts against the limiting groove 531 arranged in the pivot seat 53, and the other end of the torsional spring 52 abuts against the lower surface of the pressing portion 62 of the lock arm 6, so that the torsional spring 52 is stably arranged between the pivot seat 53 and the lock arm 6, and the front end of the lock arm 6 is pressed downward under the elastic force of the torsional spring.

[0032] The lock frame 4 is a non-closed ring, which can be more conveniently installed on the male head 2. The lock frame 4 is made of metal, which has a more stable structure, and of course, the lock frame 4 can also be made of hard plastic.

[0033] The connecting frame 5 is provided with a plurality of positioning holes 55 which are positioned with the positioning columns provided on the outer surface of the male head 2, so that the lock frame 4 is fixed to the outer surface of the male head 2; or a second screw is screwed through the positioning hole 55 and the male head 2, so that the lock frame 4 is fixed to the outer surface of the male head 2. No matter which installation mode is adopted, the connecting frame 5 can be fixed to the outer surface of the male head 2.

[0034] The number of the pulling holes 211 is two, which are distributed side by side on the rear side of the handle part 21, and two fingers can pass through the two pulling holes 211, so that the force can be better applied to pull out the male head.

[0035] The male head 2 is provided with a -type protrusion 22 for indicating the negative pole and a +type protrusion 23 for indicating the positive pole on one end surface, which has an indicating effect, so that the male head can not be inserted reversely, and the use is more convenient and safe.

[0036] In the process of inserting the male head 2 into the counter plug opening 10 of the female seat 1, the lock hook 61 at the front end of the lock arm 6 first contacts the upper end of the lock block 41 of the lock frame 4 and is blocked by the lock block 41, so that the lock hook 61 at the front end of the lock arm 6 is forced to move upward and compress the torsion spring 52. When the lock hook 61 at the front end of the lock arm 6 passes the upper end of the lock block 41 of the lock frame 4 and is placed above the lock slot 411 on the rear side of the lock block 41, the lock hook 61 is buckled in the lock slot 411 under the elastic force of the torsion spring 52, so that the lock arm 6 and the lock block 41 are locked together, the connection of the female seat 1 and the male head 2 is more stable, the male head 2 is prevented from being separated from the female seat 1 accidentally, and the female seat 1 and the male head 2 form a stable electrically conductive connection. In addition, the handle part 21 is provided on the rear side of the male head 2, and the handle part 21 is provided with at least one pulling hole 211 which penetrates through both side surfaces and through which a finger can pass. When the male head 2 needs to be pulled out relative to the female seat 1, the index finger passes through the pulling hole 211 of the handle part 21, and the thumb presses the pressing part 62 at the rear end of the lock arm 6, so that the lock hook 61 at the front end of the lock arm 6 is separated from the lock slot 411 to achieve the purpose of unlocking. At this time, the handle part 21 is pulled out with force, and since the index finger passes through the pulling hole 211 of the handle part 21, the force can be better applied to pull out the male head relative to the female seat, so that the operation is very convenient.

[0037] Of course, the above only describes the specific embodiments of the utility model, and does not limit the utility model implementation range. Any equivalent changes or modifications made according to the structure, features and principles described in the utility model patent application scope should be included in the utility model patent application scope.
