Detailed Implementation

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Example: Reference Figure 1-13The diagram shows an anti-dislodgement structure for a connector of a manual maintenance switch, comprising a plug housing 1 and a socket housing 2, a handle 3, a socket contact female 5, and a pin structure 6. The plug housing 1 and the socket housing 2 are inserted together, and a protrusion is provided on the end face of the plug housing 1. The handle 3 is assembled by engaging with the protrusion through a rotating hole 300. In order to limit the plug housing 1 after it is inserted into the socket housing 2 to prevent loosening, the handle 3 is provided with a limiting component and a slide 302 for the limiting component to slide. The structure on the slide 302 is designed so that after the handle 3 is rotated 90°, the plug housing 1 can be limited to the socket housing 2 to prevent loosening.

[0039] To facilitate staff to visually observe whether the plug housing 1 is installed in place, an observation mechanism 7 is provided on the plug housing 1.

[0040] To prevent the socket contact piece 5 from being pushed out when using the plug housing 1 and the socket housing 2, an L-shaped clip 202 is provided at the position of the slot 201. In order to facilitate the installation of the socket contact piece 5, the top surface of the clip 202 is provided with a slope for guidance. After the installation of the socket contact piece 5 is completed, a secondary protection is provided by the pin structure 6.

[0041] As one implementation method in this embodiment, in order to prevent dust and moisture from entering the interior and affecting the electrical connection performance when the device is in use, a sealing groove 200 is provided on the end face of the socket housing 2. A set of sealing strips 4 are installed in the sealing groove 200. After the connection between the plug housing 1 and the socket housing 2 is completed, the sealing strips are located in the gap between the plug housing 1 and the socket housing 2, which plays an isolation role, thereby reducing the occurrence of the above situation and indirectly extending the service life.

[0042] As one implementation method in this embodiment, the observation mechanism 7: a set of support members 100 are provided on the inner wall of the plug housing 1 (e.g., Figure 7 As shown, a set of sliding grooves 104 are provided in the inner cavity 101 of the support member 100 (on the inner wall of the plug housing 1), and a switching groove 103 is provided on the inner wall of the sliding groove 104. An observation hole 102 connected to the switching groove 103 is provided on the outer wall of the plug housing 1. Holes corresponding to the outside are provided on the support member 100 and the plug housing 1.

[0043] A set of drive rods 12 are rotatably connected in the aforementioned hole. Two drive rods 12 form a set, and their opposite sections are gear sections (the segmented design is for ease of installation and use). Two sets of symmetrical support plates are provided on the inner wall of the plug housing 1 (the two sets of support plates are centered on the slide groove 104). A set of adapter gears 11 are rotatably connected on the support plates. The gear section of the drive rod 12 meshes with the adapter gear 11. Therefore, in order to drive the adapter gear 11 to rotate, the outer end face of the drive rod 12 is connected to the handle 3 through the synchronizing member 13. When the handle 3 rotates, the drive rod 12 rotates synchronously under the action of the synchronizing member 13.

[0044] A set of observation plates 8 are slidably connected in the switching groove 103. The length of the observation plates 8 is less than that of the switching groove 103. Two sets of symmetrical observation blocks 9 (the two sets of observation blocks 9 are different colors) are provided on the outer wall of the observation plates 8. A set of racks 10 is provided on the outer wall of the observation plates 8. The racks 10 are slidably connected in the slide groove 104. The length of the slide groove 104 is greater than that of the racks 10. The racks 10 and the adapter gear 11 mesh with each other. Therefore, when the handle 3 is rotated, the drive rod 12 drives the observation plates 8 to move up and down so that the staff can observe the usage status through the observation hole 102.

[0045] As one embodiment of this invention, the synchronizing element 13 has a planetary groove 301 on the handle 3 and a hexagonal connecting groove 1201 on the outer end face of the drive rod 12. The limiting post 1302 is adapted to the connecting groove 1201, the planetary post 1301 is adapted to the planetary groove 301, and the planetary post 1301 and the limiting post 1302 are connected by a connecting plate 1300, thereby achieving the purpose of rotating the observation mechanism 7 when the handle 3 is rotated.

[0046] As one embodiment of this example, the limiting component has a slide 302 on the outer wall of the handle 3 for sliding, and in order to achieve the first-level limiting between the handle 3 and the plug housing 1, a release groove is provided on the plug housing 1, and a U-shaped release block 303 is provided on the slide 302. The bottom of the release block 303 is adapted to the release groove. In order to prevent the second-level limiting component 14 from falling off, two sets of symmetrical locking grooves 305 are provided on the slide 302, and a horizontal pressure plate 304 is provided above the slide 302.

[0047] Secondary limiting component 14: The end face of the lever 1400 is provided with two sets of symmetrical slide bars 1401, and the cross section of the slide bars 1401 is L-shaped. During use, the slide bars 1401 are limited in the locking groove 305 by the protrusion on the bottom surface. The groove on the top surface of the slide bars 1401 cooperates with the slide bars 1401 on the bottom surface of the horizontal pressure plate 304. A set of inclined secondary limiting plates 1402 is provided between the two sets of slide bars 1401. During use, the secondary limiting plates 1402 limit the release block 303 through the auxiliary block 105 to achieve secondary locking.

[0048] The working principle of this utility is as follows: After aligning the plug housing 1 with the socket housing 2, push the plug housing 1 towards the socket housing 2. After completing the basic connection, rotate the handle 3 by 90°. The handle 3 is installed on the plug housing 1 through the rotating hole 300. At the same time as rotating the handle 3, the observation mechanism 7 is started synchronously through the synchronizing component 13.

[0049] The rotating handle 3 drives the planetary column 1301 to rotate via the planetary slot 301. The planetary column 1301 drives the limiting column 1302 to rotate via the connecting plate 1300. The rotating limiting column 1302 drives the drive rod 12 to rotate on the support member 100 via the connecting slot 1201. The gear segment of the drive rod 12 is located in the inner cavity 101. The gear segment drives the corresponding adapter gear 11 to rotate in the inner cavity 101. The adapter gear 11 meshes with the rack 10, thereby driving the observation plate 8 to slide in the switching slot 103, causing the two sets of observation blocks 9 to move up and down and switch at the position of the observation hole 102. This allows the operator to observe the color of the exposed observation block 9 to determine whether it is locked in place. When the plug housing 1 is locked on the socket housing 2, the sealing strip 4 provided in the sealing slot 200 seals the connection between the two to prevent dust and moisture from entering the interior and affecting the electrical connection performance.

[0050] After the handle 3 is rotated 90°, the auxiliary block 105 is inserted between the U-shaped release blocks 303. The protruding part at the bottom of the release block 303 is locked into the release groove to achieve the first-level limit. Then, the second-level limiter 14 is pushed, the lever 1400 slides in the slide rail 302, and the slide bar 1401 slides between the horizontal pressure plate 304 and the slide rail 302, so that the second-level limiter 1402 slides down on the auxiliary block 105 and presses down and abuts against the release block 303 to achieve the second-level protection.

[0051] When it is necessary to release the limit of handle 3, the limit of release block 303 is released by pulling the secondary limit member 14 outward, and then the release block 303 is moved to leave the release groove, thereby releasing the connection between handle 3 and plug housing 1.

[0052] When the equipment needs maintenance, remove the plug housing 1, then remove the socket housing 2. After completing the above operations, remove the pin structure 6 to release the restriction on the two sets of socket contact female pieces 5 located in the slot 201. Then, move the clip 202 in the opposite direction to make the two sets of clips 202 open outward, releasing the restriction on the socket contact female pieces 5. Take out the socket contact female pieces 5. After the inspection and maintenance are completed, reinsert the socket contact female pieces 5 into the slot 201 along the inclined surface of the clip 202. Reinstall the pin structure 6 again, and then reinstall the socket housing 2 back in its original position.
