[0029] The present application will be further illustrated in conjunction with the accompanying drawings and specific embodiments.

[0030] In conjunction with Figures 1 to 3 As shown, the embodiment provides a rotary side piezoelectric connector, which includes a plug A and a socket B in plug-in cooperation with each other.

[0031] For ease of expression, in this embodiment, the end of the plug A or the socket B connecting the power line is defined as the rear end, and the other end is defined as the front end. The specific structure of the plug A and the socket B is as follows.

[0032] In this embodiment, the socket B serves as a first plug-in assembly, which includes a socket insulating body 3 as a first insulating body. In this embodiment, the socket insulating body 3 is cylindrical, and a partition plate is arranged inside the socket insulating body 3 to divide the front and rear ends of the socket insulating body 3 into a receiving groove 300 and a mounting groove 301; and a ring-shaped fixing flange ring is further arranged at the middle part of the socket insulating body 3 for locking and mounting.

[0033] The front end of the socket insulating body 3 is provided with a receiving groove 300, which is adapted to the outer diameter profile of the plug A, so that the plug A is inserted into the receiving groove 300 to realize plug-in; at the same time, the receiving groove 300 is provided with a socket rear cover 1 and a plug pin as a first plug-in part. In this embodiment, the plug pin has two types, which are a 1mm diameter elastic pin 21 and a 6mm diameter rigid pin 22. In this embodiment, the elastic pin 21 and the rigid pin 22 are both copper conductive plug pins, the rear end of which is connected with a wire, which is then loaded into the receiving groove 301, and finally loaded into the socket rear cover 1, so that the rear end of the elastic pin 21 and the rigid pin 22 abuts against the socket rear cover 1 to realize fixation and support, and the front end penetrates through the partition plate and protrudes into the receiving groove 300 to connect the conductive terminal of the plug A.

[0034] In conjunction with Figure 4 and Figure 5 In this embodiment, the plug A serves as a second plug-in assembly, which includes a cylindrical plug insulating body 5, and the front and rear ends of the plug insulating body 5 are respectively provided with a plug end cover 4 and a plug rear cover 6 in the shape of a disc.

[0035] The plug A is also provided with a second plug member, in this embodiment, the second plug member has two types, a first plug hole 71 with a 1mm diameter and a second plug hole 72 with a 6mm diameter, in this embodiment, the first plug hole 71 and the second plug hole 72 are both copper conductive terminals with holes, which are connected to the power cord and then installed in the plug A.

[0036] The specific installation method is as follows:

[0037] The plug end cover 4 is provided with two groups of first mounting holes, the first plug hole 71 is installed in the plug end cover 4 through the first mounting hole, the plug end cover 4 is installed on the plug insulating body 5, and the front end face of the plug insulating member 5 abuts against the first plug hole 71, so as to realize axial fixation. Similarly, the plug rear cover 6 and the plug insulating member 5 are both provided with through holes for passing through the first plug hole 71 or the connecting wires, so as to realize line installation. Similarly, the plug end cover 4 is also provided with a through hole penetrating to the plug member at one end facing the socket B, so as to realize the plug connection of the connector terminal.

[0038] The second plug hole 72 is fixed by the cooperation of the plug rear cover 6 and the plug insulating body 5, specifically: the second plug hole 72 is installed from the rear side of the plug insulating body 5, then the plug rear cover 6 is fixed on the rear side of the plug insulating body 5 by a cylindrical head screw, and abuts against the second plug hole 72, so as to realize axial fixation. At the same time, the front end of the second plug hole 72 penetrates the plug insulating body 5 and is inserted into the plug end cover 4.

[0039] In this embodiment, the spring needle 21 and the first plug hole 71 are in contact in the background technology, which realizes electrical connection. However, the second plug hole 72 and the spring needle 22 can be regarded as rigid members, in order to realize electrical connection, the embodiment adopts the method of laterally applying positive pressure.

[0040] Specifically, the plug end cover 4 is rotatably installed on the front end face of the plug insulating body 5 by a plug screw 40 as an installation shaft, so as to realize the rotatable installation of the plug end cover 4. In the present application, the rotation of the plug end cover 4 refers to the rotation relative to the plug insulating body 5, in actual operation, the plug insulating body 5 can be actually rotated or both can be differentially rotated, as long as relative rotation is generated, so that the plug end cover 4 serves as a rotating end cover, and cooperates with the plug insulating body 5 as a second insulating body to form a rotary pressure mechanism.

[0041] To realize the driving of the spinning mechanism, two cylindrical compression springs 8 are symmetrically arranged between the plug end cover 4 and the plug insulating body. The plug insulating body 5 is provided with two arc-shaped grooves 52, and the rear end surface of the plug end cover is also provided with an arc-shaped groove at the corresponding position. After locking, the two arc-shaped grooves form a spring groove with the plug end cover 4 as the shaft and the arc-shaped extension. The two compression springs 8 are arranged in the spring groove, and the two ends of the compression spring 8 abut against the plug end cover 4 and the plug insulating body 5, respectively, so as to realize the application of the circumferential torque to the plug end cover 4.

[0042] The plug insulating body 5 is provided with a first jack groove 571 and a second jack groove 572 corresponding to the positions of the first jack 71 and the second jack 72. The first jack groove 571 is a circular arc-shaped groove to avoid abutting against the spring needle 21 during rotation. The sidewall of the second jack groove 572 can abut against the second jack 72. After the rigid needle 22 is inserted into the second jack 72, the plug end cover 4 and the plug insulating body 5 of the spinning mechanism are connected in a lateral compression manner. In this embodiment, the plug insulating body 5 is fixed in the circumferential position relative to the socket insulating body 3. The plug end cover 4 is laterally compressed against the rigid needle 22 under the action of the torque, so that the rigid needle 22 abuts against the inner side of the second jack 72, thereby ensuring the stability of the connection. Of course, in other specific embodiments, the plug end cover 4 can also act on the second jack 72, or the plug end cover 4 is installed at the rear end of the plug insulating body 5, which can also achieve the technical effect of lateral compression.

[0043] The inventor has found that the existing connector has contact and friction during plugging, which causes wear. Due to the existence of contact wear, the service life of the connector is limited by related factors of the elastic element, and the connection stability is affected, so it is difficult or economical to realize high plugging of the connector.

[0044] Therefore, the embodiment also provides a further optimized plug-in structure without plug-in force to eliminate the problem of plug-in wear and realize efficient plug-in and improve the stability of the connector.

[0045] Specifically, as shown in Figure 1 , Figure 6 and Figure 7 , the socket insulating body 3 and the spinning mechanism are also provided with a guide mechanism. In this embodiment, the guide mechanism includes two cuboid guide blocks 31 arranged on the inner sidewall surface of the accommodation groove 300 of the socket insulating body 3 as the first guide part, and the first linear sliding groove 41 and the second linear sliding groove 51 arranged on the side surfaces of the plug end cover 4 and the plug insulating body 5 as the second and third guide parts, respectively. In the reset state without external force, the first linear sliding groove 41 and the second linear sliding groove 51 are arranged in a staggered manner.

[0046] Meanwhile, the opening end of the second straight sliding slot 51, i.e. the front end, is also provided with a barb structure, the front end of the barb extending through a guide slope and being connected to the first straight sliding slot 41 for guiding the guide block 31.

[0047] The working principle of the guide mechanism is as follows: during the insertion of the connector plug A into the socket B, the plug A is inserted along the guide block 31, i.e. is loaded into the accommodating groove 300 in the insertion direction F1; after abutting against the guide slope, the plug insulating body 5 is rotated in the rotation direction F2 with the plug screw 40 flat surface as the rotation axis surface and the spring is compressed, so as to ensure that the pin terminal 22 and the second socket terminal 72 are inserted and nested without side pressure and contact. After rotating to a certain position, the connector plug A can be continuously inserted, and after the socket B is inserted into place, the plug insulating body 5 is rotated back to the original position under the action of the compression spring 8, so that the second socket terminal 72 is axially reset and pressed on the pin terminal, i.e. the pin 22, to realize connection. At this time, the circumferential direction side pressure generated by the spring becomes the normal stress source of the contact pair, which ensures the stability of the contact. During this process, The pin hole member is contacted by side pressure, The pin is contacted by a spring pin structure to realize electrical connection.

[0048] In other specific embodiments, the guide block and the guide groove of the guide mechanism can also be provided with a groove structure on the socket and a protruding block structure on the plug. As long as one of the guide block and the guide groove is provided on the socket insulating body and the other is provided on the plug, and the first guide part provided on the rotating end cover and the third guide part provided on the second insulating body are formed and arranged in a staggered manner, the insertion process can be guided and the plug can be pulled out without wear.

[0049] In addition, in other embodiments, as long as the guide mechanism includes two guide parts provided on the socket insulating body and the plug end cover respectively, the plug insulating body can also be rotated manually, and the plug can also be pulled out without wear.

[0050] Although the present application is specifically shown and described in connection with the preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the spirit and scope of the present application as defined in the appended claims.
