Further, the first position-limiting sleeve 362 includes a first sliding portion 3621, a first position-limiting portion 3622, a second sliding portion 3623 and a third step portion 3624 which are fixedly connected in sequence, the first sliding portion 3621 is slidably attached to the outer side of the protruding portion 324, the inner diameter of the first position-limiting portion 3622 is smaller than the inner diameter of the first sliding portion 3621, the inner diameter of the second sliding portion 3623 is smaller than the inner diameter of the first position-limiting portion 3622, and the first step surface is located on the inner side of the second sliding portion 3623 so as to form a first accommodating space by enclosing with the protruding portion 324 and the connecting sleeve 361; the third step 3624 has an inner diameter larger than that of the second sliding portion 3623, and the second step surface is located inside the third step 3624.

In practical applications, the plug-in component 36 further includes a first spring 365, the first spring 365 is disposed in the first accommodating space, one end of the first spring 365 abuts against the protruding portion 324, and the other end abuts against the second sliding portion 3623, the first spring 365 is configured to provide a pre-tightening force that the first limiting sleeve 362 has a tendency of sliding towards the limiting protrusion 3611 along the longitudinal direction of the second conductive pillar 34.

As explained with reference to fig. 4, the first sliding portion 3621 is attached to the outer side of the protruding portion 324, and the inner diameter of the first position-limiting portion 3622 is smaller than the inner diameter of the first sliding portion 3621, so that the first position-limiting sleeve 362 is limited by the protruding portion 324 when sliding to the left; second sliding part 3623 laminates in adapter sleeve 361, and the one end of adapter sleeve 361 is provided with spacing arch 3611, just also makes first stop collar 362 can receive spacing of spacing arch 3611 when sliding towards the right side, and the left and right directions is all spacing, prevents that first stop collar 362 from breaking away from adapter sleeve 361.

Meanwhile, the limiting protrusion 3611 is located on one side, away from the connecting seat 10, of the clamping hole, and meanwhile, the first step surface on the inner side of the second sliding portion 3623 covers the clamping hole when sliding, and the first spring 365 acts on the first limiting sleeve 362 to be pressed towards the right side, so that the first step surface covers the clamping hole all the time, and the first step surface is ensured to provide pressure towards the inner cavity of the connecting sleeve 361 for the clamping piece 364.

In addition, the distance between the second step surface and the second position-limiting sleeve 363 is greater than the radial dimension of the clamping member 364, that is, when a pushing force is applied to the first position-limiting sleeve 362, the first position-limiting sleeve 362 moves towards the left, so that the second step surface corresponds to the clamping hole. At this moment, the clamping member 364 that originally can only move towards the inside of the connecting sleeve 361 can move towards the outside, so that the clamping member 364 extends into the inner cavity of the connecting sleeve 361 and is withdrawn, the clamping member 364 is no longer clamped in the connecting male head 20 or the low-voltage cable plug, and the connecting male head 20 and the low-voltage cable plug can be pulled out.

Of course, in order to avoid the engaging member 364 from being separated from the engaging hole, in some embodiments, when one end of the connecting sleeve 361 abuts against the protruding portion 324, the length of the first limiting portion 3622 and the first sliding portion 3621 along the lengthwise direction of the second conductive pillar 34 is smaller than the length of the distance between the one end of the connecting sleeve 361 abutting against the protruding portion 324 and the engaging hole in the direction, so as to ensure that the engaging hole can be entirely exposed and cannot be shielded by the second sliding portion 3623 when the first limiting sleeve 362 slides towards the left.

In addition, the value obtained by subtracting the aperture of the clamping hole from the length of the first limiting portion 3622, the second sliding portion 3623 and the third step portion 3624 along the longitudinal direction of the second conductive pillar 34 is greater than the distance between the end of the connecting sleeve 361 abutting against the protruding portion 324 and the clamping hole in the direction, so as to ensure that the second step surface covers the clamping hole when the first limiting sleeve 362 slides to the left and cannot slide.

In practical application, the limiting protrusion 3611 is also annular, and the inner diameter of the third step 3624 is larger than the outer diameter of the limiting protrusion 3611, and specifically, is slightly larger than the outer diameter of the limiting protrusion 3611, so that when the first spring 365 pushes the first limiting sleeve 362 to abut against the limiting protrusion 3611 towards the right, the second sliding portion 3623 abuts against the limiting protrusion 3611, thereby ensuring that the first step surface covers the whole clamping hole at this time.

In some embodiments, the connecting sleeve 361 includes a third connecting portion 3612 and a second position-limiting portion 3614, one end of the third connecting portion 3612 is screwed to the outer side of the second connecting portion 326, the second position-limiting portion 3614 is fixedly connected to the other end of the third connecting portion 3612 away from the second connecting portion 326, the engaging hole is opened in the second position-limiting portion 3614, and the position-limiting protrusion 3611 is located on the outer side of the second position-limiting portion 3614.

Further, the inner diameter of the third connecting portion 3612 is greater than the outer diameter of the recessed portion 328, the inner diameter of the second limiting portion 3614 is smaller than the inner diameter of the third connecting portion 3612, and the second connecting portion 326, the recessed portion 328, the third connecting portion 3612 and the limiting portion enclose to form a second accommodating space.

In practical applications, the second position-limiting sleeve 363 mutually includes a third position-limiting portion 3632 and a third sliding portion 3634, an outer diameter of the third position-limiting portion 3632 is larger than an outer diameter of the third sliding portion 3634, the outer diameter of the third position-limiting portion 3632 is smaller than an inner diameter of the third connecting portion 3612, and an outer side of the third sliding portion 3634 is slidably attached to an inner side of the second position-limiting portion 3614.

The outer side of the third sliding portion 3634 is attached to the inner side of the second limiting portion 3614, and the outer diameter of the third limiting portion 3632 is larger than the outer diameter of the third sliding portion 3634, that is, when the third sliding portion 3634 slides towards the right, the third limiting portion 3632 is abutted to the second limiting portion 3614, so as to limit the sliding of the second limiting sleeve 363.

In some embodiments, the plug-in component 36 further includes a second spring 366, the second spring 366 is disposed in the second accommodating space, one end of the second spring 366 abuts against the second connecting portion 326, and the other end abuts against the third limiting portion 3632, the second spring 366 is configured to provide a pre-tightening force that makes the second limiting sleeve 363 have a tendency of sliding towards the limiting protrusion 3611 along the longitudinal direction of the second conductive pillar 34.

The second position-limiting portion 3614 of the connecting sleeve 361 limits the position of the second position-limiting sleeve 363, and the second spring 366 actually provides a pressure to make the second position-limiting sleeve 363 press against the second position-limiting portion 3614. It is determined without any doubt that the second limiting sleeve 363 can cover the clamping hole in the sliding process, and meanwhile, a limit position exists in the rightward sliding process, when the second limiting sleeve 363 abuts against the second limiting portion 3614, the second limiting sleeve 363 cannot move towards the right, the clamping hole is formed in the second limiting portion 3614, at this time, the second limiting sleeve 363 covers the clamping hole, and if the clamping hole is to be exposed, the pressure of the second spring 366 needs to be overcome, so that the second limiting sleeve 363 slides towards the left.

In some embodiments, the connecting sleeve 361, the first position-limiting sleeve 362 and the second position-limiting sleeve 363 are all tubular structures made of aluminum alloy materials, and the recess 328 is located in the inner cavity of the connecting sleeve 361 after the connecting sleeve 361 is connected to the socket main body 32.

It should be explained in conjunction with the above embodiments that the plugging structure is used for connecting with the connection male plug 20 or the low voltage cable plug, and the plugging structure is actually composed of the above-mentioned cylindrical connection cavity 321 of the socket main body 32, the second conductive pillar 34 and the matching blind hole 342 at one end thereof, and the partial structure of the plug-in component 36 refers to the inner cavity of the connection sleeve 361, the first limiting sleeve 362, the second limiting sleeve 363, the first spring 365, the second spring 366 and the clamping piece 364, which are matched to form the plugging structure that can be plugged with the connection male plug 20 or the low voltage cable plug.

In some embodiments, the catch 364 is a steel ball. It can be understood that the clamping member 364 is used for clamping and connecting the male plug 20 or the low voltage cable plug, that is, when the clamping member 364 is clamped and connected to the male plug 20 or the low voltage cable plug, the clamping member 364 is still partially located in the clamping hole, so that the male plug 20 or the low voltage cable plug is clamped and connected to the plugging structure.

Meanwhile, it should be noted that the clamping member 364 is a steel ball, the first limiting sleeve 362 and the second limiting sleeve 363 are both made of aluminum alloy, and although a certain pressure exists between the first limiting sleeve 362 and the steel ball and between the second limiting sleeve 363 and the steel ball, the pressure does not cause the first limiting sleeve 362 and the second limiting sleeve 363 to deform, and the pressure can still make the first limiting sleeve 362 push the steel ball towards the inner cavity of the connecting sleeve 361.

In order to facilitate understanding of the working process of the plugging structure, the principle of the plugging structure and the male connecting head 20 when the male connecting head 20 is plugged into the plugging structure is described with reference to the accompanying drawings:

when connecting public head 20 and inserting the grafting structure, the outside of public head seat 22 is roughly to cooperate with column connection cavity 321, first conductive pillar 24 stretches into in the cooperation blind hole 342 of second conductive pillar 34, and the external diameter of joint ring 26 is the same with the internal diameter of spacing portion 3614 of second during the design, and seted up joint groove 262 on the joint ring 26, when connecting public head 20 and inserting wherein, joint ring 26 can promote second stop collar 363 towards the left side, at least joint groove 262 corresponds the joint hole, the joint spare 364 that is located the joint hole behind the corresponding joint hole can be promoted by first stop collar 362, fall into joint groove 262, thereby will connect public head 20 card.

It should be noted that, in order to facilitate the insertion, the clamping groove 262 is a groove formed in the outer side of the clamping ring 26, and compared with the clamping groove 262 with the same number of clamping holes, the clamping groove 262 is a whole groove, so that the connection socket 30 can be inserted without corresponding to the clamping holes, and the convenience of the insertion is improved.

When the male connection head 20 needs to be pulled out, the first limiting sleeve 362 slides towards the left side until the second step surface corresponds to the clamping hole, and because the clamping piece 364 is a steel ball, and meanwhile, the second spring 366 always provides pressure for the second limiting sleeve 363, the second limiting sleeve 363 also provides pressure towards the right side for the male connection head 20, when the second step surface corresponds to the clamping hole, the male connection head 20 extrudes the steel ball towards the second step surface, so that the steel ball moves towards the second step surface, and until the second spring 366 pushes the second limiting sleeve 363 to abut against the second limiting part 3614.

At this time, the male connector 20 can be directly pulled out, and the first stopper 362 can be reset after the pulling-out (reset by the first spring 365 in a state where the second sliding portion 3623 abuts on the stopper protrusion 3611). Of course, the first stop sleeve 362 can be reset after the male connector 20 is moved outward, and the first stop sleeve does not need to be reset after the male connector 20 is pulled out.

It is understood that the male connector 20 is fixed by the engagement of the steel ball with the engagement groove 262 formed on the engagement ring 26, and the low voltage cable plug can be engaged by the corresponding groove formed at the corresponding position. In addition, the cooperation between the steel ball and the clamping groove 262 can be other structures as long as the clamping piece 364 can be ensured to be clamped in the clamping groove 262 and can be extruded to the second step surface by the connecting male head 20 or the low-voltage cable plug.

In some embodiments, the radial dimension of the first spring 365 is greater than the radial dimension of the second spring 366, however, the first spring 365 and the second spring 366 are both 304 stainless steel metal springs.
