[0026] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0027] To address the problem of mis-insertion of connector plugs and sockets when multiple identical power connectors are installed in the same cabinet under different wiring conditions, this invention proposes a power connector designed to prevent mis-insertion. By adding identification and limiting components to the same type of power connector, multiple different models of power connectors can be formed without changing the original structure of the power connector, thereby avoiding mis-insertion of connector plugs and sockets.
[0028] like Figure 1 and Figure 2 As shown, the anti-misplugging power connector proposed in this utility model includes a plug assembly, a socket assembly, an identification pin, an open retaining ring, and a plug. The plug assembly includes a plug base 1, and the socket assembly includes a socket base 2.
[0029] The plug base has multiple identification pin mounting holes 3 on both sides. In this invention, four identification pin mounting holes are symmetrically arranged on both sides of the plug base, such as... Figure 1 As shown in (b), the identification pin mounting hole is provided with a first positioning step 14 for positioning the insertion depth of the identification pin. The identification pin mounting hole is divided into an upper part and a lower part by the first positioning step, and the diameter of the upper part is smaller than the diameter of the lower part. The socket base has identification pin insertion holes on both sides, each corresponding to one of the multiple identification pin mounting holes. In this utility model, the socket base also has four identification pin insertion holes 4 symmetrically arranged on each side, as shown... Figure 2 As shown in (c), the identification pin socket is provided with a second positioning step 15 to facilitate the installation of the plug. The identification pin socket is divided into an upper part and a lower part by the second positioning step. The diameter of the upper part is larger than the diameter of the lower part. The plug blocks the holes where the identification pin does not need to be inserted, thereby preventing connector plugs of different models from being inserted into the socket. Preferably, the diameters of the identification pin mounting hole and the identification pin socket are both slightly larger than the diameter of the identification pin to facilitate the insertion of the identification pin into the hole.
[0030] like Figure 3 and Figure 4 As shown, the identification pin 5, as the main component for identifying the model number, is fixed in the identification pin mounting hole of the plug base by an open retaining ring and a first positioning step. Specifically, the identification pin is cylindrical, tapering from top to bottom, and is divided into a top section, a middle section, and a bottom section from top to bottom. In practice, this identification pin structure matches the structure inside the identification pin mounting hole; the diameters of the top and middle sections of the identification pin are the same as the diameter of the upper part of the identification pin mounting hole, and the diameter of the bottom section is the same as the diameter of the lower part of the identification pin mounting hole. For example... Figure 3 As shown, the top part has a chamfer to facilitate insertion into the mounting hole; the middle part has a circumferential groove 6, which matches the open retaining ring 7 to fix the identification pin inserted into the identification pin mounting hole onto the plug base; the bottom of the lower end is hemispherical to facilitate alignment of the identification pin insertion into the socket base.
[0031] Additionally, the length from the bottom of the slot in the identification pin to the connection point between the middle and lower ends is equal to the height of the upper part of the identification pin mounting hole, such as... Figure 4 As shown, the open-ended retaining ring is a circular structure with one end open. The opening at the center of the circular structure matches the retaining groove, as shown. Figure 6 As shown, the identification pin is passed through the identification pin mounting hole from bottom to top. The middle part of the identification pin is locked at the first positioning step, while the top part of the identification pin and the slot protrude from the identification pin mounting hole. At this point, an open retaining ring is used to lock it into the slot, thereby fixing the identification pin in place. Furthermore, the length of the lower part of the identification pin is greater than the height of the lower part of the identification pin mounting hole to facilitate insertion into the identification pin socket of the socket base.
[0032] like Figure 5 As shown, the plug 8, serving as an auxiliary part for model identification, is fixed inside the identification pin socket via a second positioning step. Specifically, the structure of the plug matches the structure of the identification pin socket. This plug is an elastic fixing component, facilitating installation in the corresponding socket hole of the socket base and automatic fixation. The plug includes a front end and a rear end. The diameter and height of the front end are the same as the diameter and height of the lower part of the identification pin socket. The top of the front end has a protruding conical structure 9, which facilitates entry into the socket. Furthermore, the middle of the front end has a vertical slot 10, allowing it to deform and enter the identification pin socket by compressing the conical structure. After installation, it springs open to fix the plug. The rear end has a fixing component 11 that matches the upper part of the identification pin socket. The diameter and height of this fixing component are the same as the upper part of the identification pin socket, further securing the plug. Figure 7 As shown, the plug is installed into the identification pin insertion hole with the front end facing down. The tapered structure on the front end of the plug is deformed by squeezing it to enter the identification pin insertion hole until the front end protrudes out of the identification pin insertion hole. At this time, the tapered structure returns to its original shape and fixes the plug. The fixing structure at the rear end of the plug also matches the upper part of the identification pin insertion hole to further fix the installed plug.
[0033] Furthermore, for power connectors of the same model, the selectively installed identification pin positions in the identification pin mounting holes of the plug base correspond one-to-one with the positions of the unplugged identification pin sockets in the identification pin mounting holes of the socket base; while for power connectors of different models, different numbers and positions of identification pins are selectively installed in the identification pin mounting holes of the plug base. For example... Figure 8 As shown, the identification pins in the connector plug of the same model can be inserted into the identification pin sockets on the connector socket of the same model; such as Figure 9 As shown, the identification pins are installed in different positions in connector plugs of different models. When an incorrect connector is inserted into a non-corresponding socket, it will hit the plug and cannot be inserted. This design avoids the situation of mis-inserting different models of power connectors.
[0034] In this invention, an identification pin is installed on each side of the plug base. Instead of inserting plugs into the corresponding holes on both sides of the socket base, plugs are inserted into the other identification pin holes, thus achieving the anti-misinsertion function for the current model of power connector. Preferably, the plug base and socket base each have four holes, allowing for the design of 16 different models of power connectors to meet diverse needs. Taking three of them as examples, the specific details are as follows... Figure 10 As shown.
[0035] In one embodiment, the plug base has multiple locking through holes 12, and the socket base has multiple locking threaded holes 13. Corresponding locking through holes 12 and locking threaded holes 13 are fixed by bolts, thereby further securing the connection between the plug and the socket. Furthermore, the plug base and socket base are polygonal structures; in this invention, they are designed as commonly used rectangular structures. The locking through holes and locking threaded holes are respectively located at the corners of the polygonal structure, facilitating bolt fixing and installation.
[0036] The above design can meet the anti-misinsertion function of various models of power connector plugs and sockets, and can also realize the anti-misinsertion function of power connectors of the same type under different wiring conditions.
[0037] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
