As shown in fig. 1 to 3, this embodiment provides a rotational-side piezoelectric connector including a plug a and a receptacle B that are plug-fitted to each other.

For convenience, in this embodiment, one end of the plug a or the socket B connected to the power line is defined as a rear end, and the other end is defined as a front end. The specific structure of the plug a and the receptacle B is as follows.

In this embodiment, the socket B is used as a first plug assembly, and includes a socket insulating body 3 as a first insulating body, in this embodiment, the socket insulating body 3 is cylindrical, and a partition is disposed therein to divide front and rear ends of the socket insulating body 3 into a receiving groove 300 and a mounting groove 301; the middle part of the socket insulating main body 3 is also provided with an annular fixed flange ring for locking installation.

In this embodiment, the elastic pin 21 and the rigid pin 22 are copper conductive pins, the rear ends of which are connected with wires, and then are installed in the containing groove 301, and finally are installed in the rear cover 1 of the socket, so that the rear ends of the elastic pin 21 and the rigid pin 22 are abutted against the rear cover 1 of the socket to realize fixing and supporting, and the front ends of the elastic pin and the rigid pin penetrate through the partition board and then protrude into the containing groove 300 for connecting with the conductive terminals of the plug a.

Referring to fig. 4 and 5, in this embodiment, the plug a is used as a second plug assembly, and includes a cylindrical plug insulating body 5, and the front end and the rear end of the plug insulating body 5 are respectively provided with a plug end cover 4 and a plug rear cover 6 in a disc shape.

The plug a is also provided with two jack members as a second plug member, in this embodiment, the jack members are a first jack 71 with a hole diameter of 1 mm and a second jack 72 with a hole diameter of 6 mm, in this embodiment, the first jack 71 and the second jack 71 are copper conductive terminals with holes, and the conductive terminals are connected with a power cord and then are installed in the plug a.

The specific installation mode is as follows:

two groups of first mounting holes are formed in the plug end cover 4, after the first jack 71 is installed in the plug end cover 4 through the first mounting holes, the plug end cover 4 is installed on the plug insulating part 5, the front end face of the plug insulating part 5 abuts against the first jack 71, and axial fixing is achieved. Similarly, the plug rear cover 6 and the plug insulator 5 are provided with through holes for passing through the first insertion holes 71 or connecting wires thereof, so as to realize line installation. Similarly, a through hole penetrating to the jack member is further formed in one end of the plug end cover 4 facing the socket B, so that the terminal in the connector can be plugged.

This second jack 72 is fixed through lid 6 and the cooperation of plug insulation main part 5 behind the plug, and is specific: the plug insulating body 5 is fitted into the second insertion hole 72 from the rear side, and then the plug rear cover 6 is fixed to the rear side surface of the plug insulating body 5 by means of a cap screw and abuts against the second insertion hole 72, thereby achieving axial fixation thereof. Meanwhile, the front end of the second insertion hole 72 also penetrates through the plug insulating main body 5 and is inserted into the plug end cover 4.

In this embodiment, the inserted pogo pin 21 and the first insertion hole 71 are in contact with each other by the elastic terminal structure in the background art, so as to realize electrical connection. The second receptacle 72 and the rigid pin 22 can be considered as rigid members, and a positive pressure is applied laterally in this embodiment to make the electrical connection.

The method specifically comprises the following steps: the plug end cover 4 is rotatably mounted on the front end face of the plug insulating main body 5 through a plug screw 40 as a mounting shaft, so that the plug end cover 4 is rotatably mounted. In the present invention, the rotation of the end cap 4 refers to the rotation relative to the plug insulating body 5, and in the actual operation, the plug insulating body 5 may actually rotate or the two may rotate differently, so long as the relative rotation is generated, so that the plug end cap 4 serves as a rotating end cap and cooperates with the plug insulating body 5 serving as a second insulating body to form a spinning mechanism.

In order 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 main body: the plug insulating main body 5 is provided with two arc-shaped grooves 52, and similarly, the arc-shaped grooves are also arranged at corresponding positions on the rear end face of the plug end cover, the two arc-shaped grooves are matched to form a spring groove which takes the plug screw 40 as an axis and extends in a circumferential arc shape after locking, the two compression springs 8 are respectively arranged in the spring groove, and two ends of each compression spring 8 respectively abut against the plug end cover 4 and the plug insulating main body 5, so that circumferential torque is applied to the plug end cover 4.

A first jack groove 571 and a second jack groove 572 are respectively disposed on the plug insulating main body 5 at positions corresponding to the first jack 71 and the second jack 72, wherein the first jack groove 571 is a circular arc groove to prevent the elastic pin 21 from being abutted by the rotation process, and a sidewall of the second jack groove 572 can be abutted against the second jack 72. After the rigid pin 22 is inserted into the second insertion hole 72, the plug end cover 4 and the plug insulation main body 5 of the spinning mechanism are matched with a lateral compression connection position; in this embodiment, the plug insulating body 5 is fixed in circumferential position relative to the socket insulating body 3, and the plug end cap 4 laterally presses the rigid pin 22 under the action of torque, so that the rigid pin 22 laterally abuts against the inner side surface of the second insertion hole 72, thereby ensuring the connection stability.

Meanwhile, the open end, i.e., the front end, of the second linear sliding groove 51 is further provided with a barb structure, and the front end of the barb extends through a guide slope and is connected to the inside of the first linear sliding groove 41 for guiding the guide block 31.

The working principle of the guide mechanism is as follows: in the process of inserting the connector plug a and the connector socket B, the plug a is inserted along the guide block 31, that is, the plug a is loaded into the receiving groove 300 in the inserting direction F1; after the plug screw 40 is abutted to the guide inclined plane, the smooth surface of the plug screw 40 is used as a rotating shaft surface to rotate axially and compress the spring, namely the plug insulating main body 5 is rotated in the rotating direction F2, so that the pin terminal rigid pin 22 and the jack terminal second jack 72 are ensured to realize non-side pressure and non-contact insertion nesting. After rotating to a certain position, connector plug A can continue to insert and close, and socket B inserts and closes the back that targets in place, and plug insulating part main part 5 returns to the throne under the spring 8 effect for second jack 72 axial resets the side and presses on the contact pin terminal is just needle 22, realizes connecting. At the moment, the circumferential side pressure generated by the spring becomes a positive stress source matched with the contact pair, and the contact stability is ensured. In thatIn the course of this process, the air-conditioning system,

the pinhole pieces are contacted in a side pressure mode,the contact pins are contacted by a spring pin structure to realize electric connection.

In other specific embodiments, the guide block and the guide groove of the guide mechanism may also be groove structures on the socket, and the plug has a protrusion structure, so long as one of the guide block and the guide groove is disposed on the socket insulating main body, and the other is disposed on the spinning mechanism, and the first guide portion disposed on the rotating end cover and the third guide portion disposed on the second insulating main body are formed, and the two are arranged in a staggered manner, so that the guiding in the loading process can be realized, and the zero-abrasion plugging and unplugging can be realized.
