Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

Referring to fig. 1 to 14, a connector according to the present invention will now be described. The connector comprises a seat body 1 with a containing cavity 13 communicated with the outside, a rotating piece 2, a connecting rod 31, a power supply terminal, a first pivot 32 and a second pivot 33; the rotating part 2 is pivoted on the seat body 1 through a first pivot 32; one end of the connecting rod 31 is pivoted on the rotating part 2 through a second pivot shaft 33; the seat body 1 is provided with a sliding chute 15, and the other end of the connecting rod 31 is provided with a sliding block 34 arranged in the sliding chute 15 in a sliding way; the power supply terminal is arranged in the accommodating cavity 13 of the base body 1.

Thus, the rotating member 2 is pivoted to the base 1 via the first pivot 32; one end of the connecting rod 31 is pivoted on the rotating part 2 through the second pivot 33, and the other end of the connecting rod 31 is slidably arranged in the sliding groove 15 on the seat body 1 through the sliding block 34, so that the connecting rod 31 can play a role of guiding the rotation of the rotating part 2 in the rotating process of the rotating part 2, and in addition, the connecting rod 31 is connected on the rotating part 2, so that the rotating stability of the rotating part 2 can be improved, and the swinging is not easy to occur; when a user needs to plug and pull the connector, the rotating piece 2 is pulled, and the user plugs and pulls the connector by pinching/grabbing/hooking the rotating piece 2, so that the connector plugging and pulling device is very convenient and reduces the space occupation; the power supply terminal is arranged in the accommodating cavity 13 and can be protected, so that the plugging and unplugging of the connector are not easily hindered.

The power supply terminal supplies power to the outside, or the external power supply inputs electric energy to the power supply terminal. Specifically, the power supply terminal may be a female/male metal conductive terminal.

Further, referring to fig. 1 to 14, as an embodiment of the connector provided by the present invention, the sliding block 34 is cylindrical. So, slider 34 slides the in-process in spout 15, and the cylindric surface of slider 34 is difficult to collide with the lateral wall of spout 15.

Further, referring to fig. 1 to 14, as an embodiment of the connector provided by the present invention, the width of the sliding groove 15 is the same as the outer diameter of the sliding block 34. Thus, the slider 34 is less likely to shake when sliding along the slide groove 15.

Further, referring to fig. 1 to 14, as an embodiment of the connector provided by the present invention, the sliding groove 15 extends in a straight direction. In this way, the sliding block 34 slides more smoothly in the slide slot 15.

Further, referring to fig. 1 to 14, as an embodiment of the connector provided by the present invention, the seat body 1 has a predetermined plane surface perpendicular to the first pivot 32, and the sliding slot 15 is opened on the predetermined plane surface. Thus, when the slider 34 is slidably disposed in the slide groove 15, the link 31 connected to the slider 34 is less likely to collide with the predetermined plane surface.

Specifically, in one embodiment, the slider 34 is disposed parallel to the second pivot 33. In this way, the cylindrical slider 34 is disposed parallel to the second pivot 33, so that when the slider 34 rotates around the second pivot 33, the cylindrical outer side wall of the cylindrical slider 34 contacts the inner wall of the slide slot 15, facilitating the sliding of the slider 34.

Specifically, in one embodiment, the slider 34 is rotatably disposed on the link 31 about its axis. When the slider 34 is slidably disposed in the slide groove 15 and contacts the inner wall of the slide groove 15, the rotating slider 34 can reduce the friction between the slider 34 and the inner wall of the slide groove 15.

Specifically, in one embodiment, the slider 34 is provided with a protrusion 341, and a side wall of the sliding slot 15 is provided with a first recess 151 for the protrusion 341 to slide into. When the protruding portion 341 is engaged in the first concave portion 151, the slider 34 can be engaged in the slide groove 15, and the sliding of the slider 34 is restricted.

Specifically, in one embodiment, the first pivot 32 is parallel to the second pivot 33. In this way, when the rotating member 2 rotates around the first pivot 32, the rotating member 2 and the connecting rod 31 are not easily locked to each other while the rotating member 2 pulls the connecting rod 31 to move via the second pivot 33.

Specifically, in one embodiment, the first pivot 32 is rotatably disposed on the seat body 1 about its axis. Thus, the relative rotation between the first pivot 32 and the seat body 1 is facilitated, and the rotation part 2 rotates relative to the seat body 1.

Specifically, in one embodiment, a third through hole is formed at the front end of the lower shell 12, and a third barb which is clamped into the third through hole and hung upside down on the lower shell 12 is formed on the upper shell 11; the rear end of the lower shell 12 is provided with a fourth through hole, and the upper shell 11 is provided with a fourth barb which is clamped into the fourth through hole and hung upside down on the lower shell 12. In this way, the engagement of the third barb and the third through hole can fix the front end of the lower case 12 to the upper case 11, and the engagement of the fourth barb and the fourth through hole can fix the rear end of the lower case 12 to the upper case 11.

In particular, in one embodiment, the surface of the third barb has a third guide surface for guiding the third barb through the third through hole; and/or the surface of the fourth barb has a fourth guiding surface for guiding the fourth barb through the fourth through hole.

Specifically, in one embodiment, the number of the third through holes and the number of the third barbs are multiple respectively; the plurality of third through holes correspond to the plurality of third barbs one by one. As such, the plurality of third through holes and the third barbs cooperate to more firmly fix the upper housing 11 and the lower housing 12.

Specifically, in one embodiment, the number of the third through holes and the number of the third barbs are two respectively.
