Specific embodiments

[0025] The embodiments described below are only a part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0026] Refer to Figures 1 to 7 , a connector with a protective cover, including a connector body 1 and a connector cover 3. One end of the connector body 1 is open and a mounting plate 2 is provided outside this end. One end of the mounting plate 2 is connected to the connector cover 3 through a connecting device 4.

[0027] Refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 , specifically, in this application, the connecting device 4 includes two rotating seats 41, a rotating shaft assembly, a torsion spring 411 and a positioning ring 413. The two rotating seats 41 are symmetrically arranged on one side of the mounting plate 2. Installation holes are provided on both sides of the rotating seat 41, and the positioning ring 413 is arranged in one of the installation holes of the rotating seat 41. At the same time, in order to enable the rotational connection with the rotating shaft assembly, a rotating hole is penetrated through the rotating shaft.

[0028] Refer to Figure 2 and Figure 3, the rotating shaft assembly includes a rotating shaft 42, and two fixed discs 412 and two fixed rings 43 arranged on the rotating shaft 42. The rotating shaft 42 is arranged on the connector cover 3 and is rotatably connected to the rotating base 41. The fixed discs 412 and the fixed rings 43 are arranged oppositely and are respectively arranged on both sides of the rotating base 41, that is, one fixed disc 412 and one fixed ring 43 are respectively arranged on the left and right sides of the two rotating bases 41. A torsion spring 411 is arranged on the side of the fixed disc 412 close to the rotating base 41. The other end of the torsion spring 411 is arranged in the mounting hole on the side of the rotating base 41 away from the positioning ring 413 and the end is connected to the mounting hole. A positioning mechanism 44 and a push rod 45 are arranged on the side of the fixed ring 43 close to the rotating base 41. A first chute 46 and a second chute 47 are respectively formed on the surface of the positioning ring 413. The depth of the first chute 46 is greater than that of the second chute 47. The first chute 46 is used for the positioning mechanism 44 to slide and an arc-shaped card slot 48 is formed on the side. The arc-shaped card slot 48 is partially arranged at the second chute 47. A limiting member 49 is slidably arranged on the inner wall of the second chute 47. A through hole is formed on the surface of the limiting member 49, and the push rod 45 is inserted into the through hole.

[0029] Refer to Figure 1 , Figure 5 , Figure 6 and Figure 7, it should be noted that when the working plug needs to be inserted, the user holds the connector cover 3 by hand and gently applies force to rotate the connector cover 3. During the rotation process, the rotating shaft 42 of the connecting device 4 drives the fixed ring 43 to rotate. The positioning mechanism 44 on the fixed ring 43 slides in the first chute 46, and the push rod 45 slides in the through hole of the limiting member 49. When the positioning mechanism 44 slides to reach the arc-shaped card slot 48, the positioning mechanism 44 snaps into the arc-shaped card slot 48. At this time, the connector cover 3 is limited and remains in the open state, and the connector cover 3 maintains this open and closed state. At this time, the user can insert the male plug into the opening of the connector body 1 and connect it to the internal electrical interface. Since the connector cover 3 is limited in the open position, the user does not need to manually support the cover, and the male plug can be inserted smoothly, improving the installation convenience. When the male plug needs to be pulled out, the user gently applies force again to rotate the connector cover 3, preferably rotating it to the end of the opening and closing. At this time, the rotating shaft 42 drives the fixed ring 43 to continue rotating, and the push rod 45 on the fixed ring 43 abuts against the end of the through hole, thereby pushing the limiting member 49 to rotate. Then, the limiting member 49 reaches the arc-shaped card slot 48 and blocks the arc-shaped card slot 48. Since the positioning mechanism 44 can no longer be limited by the arc-shaped card slot 48, the positioning mechanism 44 disengages from the arc-shaped card slot 48. At this time, the torsion spring 411 starts to work, driving the connector cover 3 to automatically reset. Under the action of the torsion spring 411, the connector cover 3 smoothly rotates back to the initial closed position, and the connector cover 3 remains in the closed state, protecting the internal electrical interface from the external environment.

[0030] Refer to Figures 5 to 7 , in order to enable the push rod 45 to push the limiting member 49 only when it reaches both ends of the through hole on the surface of the limiting member 49, the middle part of the through hole has a sliding function. The diameter of the through hole on the surface of the limiting member 49 is larger than the diameter of the push rod 45.

[0031] Refer to Figure 4, preferably, the positioning mechanism 44 includes a positioning rod 441 and a return spring 442. An installation groove is provided on the fixed ring 43. The positioning rod 441 is slidably arranged in the installation groove. The bottom side of the positioning rod 441 is connected with the return spring 442, and the other end of the return spring 442 is connected with a side wall of the installation groove. The positioning mechanism 44 slides in the first chute 46. When the positioning mechanism 44 slides to the arc-shaped card slot 48, the return spring 442 provides an extrusion force for the positioning rod 441, so that the positioning rod 441 is extruded into the arc-shaped card slot 48. At this time, without applying external force, the positioning mechanism 44 will no longer slide, realizing the limit of the connector cover 3. When the positioning rod 441 needs to be disengaged from the arc-shaped card slot 48, an opening and closing force is provided for the connector cover 3, so that the push rod 45 on the fixed ring 43 drives the limiting member 49 to rotate to the arc-shaped card slot 48 and block the arc-shaped card slot 48. Since the positioning mechanism 44 can no longer be limited by the arc-shaped card slot 48, the torsion spring 411 can drive the connector cover 3 to reset at this time.

[0032] Refer to Figure 4 , preferably, the positioning rod 441 includes a sliding block and a cylindrical rod arranged on the sliding block. The sliding block is slidably arranged in the installation groove.

[0033] Refer to Figure 1 , preferably, an opening and closing push plate 4102 is arranged on the side of the connector cover 3 away from the connecting device 4. The opening and closing push plate 4102 can facilitate the user to push the connector cover 3 to rotate, improving the usability.

[0034] Refer to Figure 1 and Figure 2 , preferably, two first fixing blocks 4101 and two second fixing blocks 4104 are respectively arranged on the sides of the connector cover 3 and the mounting plate 2 away from the connecting device 4. First magnetic rings 4103 and second magnetic rings 4105 which can be magnetically connected are respectively arranged on the first fixing blocks 4101 and the second fixing blocks 4104. After the connector cover 3 rotates and resets, the first magnetic ring 4103 and the second magnetic ring 4105 attract each other, so that the connector cover 3 can be stably covered on the mounting plate 2, improving the stability.

[0035] Refer to Figure 1 , preferably, an annular accommodation groove is annularly arranged on the side of the mounting plate 2 close to the connector cover 3. An annular rubber ring 11 is arranged in the annular accommodation groove. The arrangement of the annular rubber ring 11 can effectively prevent external impurities such as dust and water vapor from entering the connector, thereby protecting the normal operation of the internal components of the connector.

[0036] Preferably, a through hole is provided through the middle of the side of the connector body 1, and a micro switch is connected to the through hole.

[0037] Preferably, mounting holes 12 are provided at the four corners of the mounting plate 2. During installation, the mounting holes 12 are aligned with the mounting holes at the installation position, and screws are screwed in to install and use the connector.

[0038] The present invention provides a connector with a protective cover. When in use, by rotating the connector cover body 3, at this time, the rotating shaft 42 rotates, and then drives the fixed ring 43 to rotate. The positioning mechanism 44 on the fixed ring 43 slides in the first chute 46. When reaching the arc-shaped card slot 48, the positioning mechanism 44 is snapped into the arc-shaped card slot 48. At this time, the connector cover body 3 is limited. Then, the male connector plug can be inserted through the opening, thereby improving the installation convenience. When the male connector plug is pulled out, continue to rotate the connector cover body 3. Then, the rotating shaft 42 drives the fixed ring 43 to continue rotating, and the push rod 45 on the fixed ring 43 drives the limiting member 49 to rotate to the arc-shaped card slot 48 and block the arc-shaped card slot 48. Since the positioning mechanism 44 can no longer be limited by the arc-shaped card slot 48, at this time, the torsion spring 411 drives the connector cover body 3 to reset. Therefore, during the use of the connector with a protective cover, not only the operation convenience is improved, the trouble of manually supporting the cover body by the user is reduced, but also through the design of the positioning mechanism 44 and the torsion spring 411, it is ensured that the connector cover body 3 can be reset in the non-working state, effectively preventing the rebound and movement of the cover body, and enhancing the overall safety and reliability.

[0039] The above-disclosed are only several preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
