Description

Technical Field

[0001] This utility model provides an anti-misinsertion electrical connector, belonging to the field of electrical connector technology. Background Technology

[0002] An electrical connector is a component used to connect electronic or electrical devices, typically for transmitting power or signals. Electrical connectors generally consist of a plug and a socket; the contact between the plug and socket enables the transmission of electrical signals. Electrical connectors are widely used in consumer electronics (such as mobile phones and computers), communication equipment, automotive electronics, aerospace, medical equipment, and military systems, among other fields.

[0003] Existing electrical connectors can generally meet normal usage needs. However, during use, misalignment or misfitting of the connector and socket can easily occur, leading to accidental insertion and damage. Furthermore, existing connectors typically use threaded or bayonet connections. Bayonet connections may not be secure enough and could come loose, while threaded connections may strip or be loosened by external force, potentially causing the connector and socket to become loose and detach. Therefore, this invention provides an anti-misfit electrical connector. Utility Model Content

[0004] The technical problem solved by this utility model is that misalignment and misfitting of the connector and socket are prone to occur, which can lead to misinsertion and damage to the connector. The use of threaded connection and bayonet connection to connect the connector and socket is not secure enough and may cause them to be pulled out. The connector and socket are also prone to loosening and falling off.

[0005] To solve the technical problem, the present invention provides the following technical solution: a connector for preventing mis-insertion, comprising a connector and a socket. The connector includes a housing and a sleeve disposed at the bottom of the housing and inserted into the socket. The socket has multiple protrusions at its top edge. The bottom of the housing has multiple grooves located outside the sleeve and matching the protrusions. One of the protrusions has symmetrically provided limiting grooves on its two side walls. One of the grooves has a limiting rail on its inner side wall that matches the limiting groove. The connector is threaded with a bolt inserted into the groove for locking the protrusion.

[0006] Furthermore, the socket includes a housing and a core disposed within the housing, and the connector also includes a pin disposed within a socket and mating with the core.

[0007] Furthermore, the protrusion is rectangular in shape, and the edges and corners of the protrusion are rounded.

[0008] Furthermore, the multiple protrusions are arranged in a triangular pattern on the top of the connector.

[0009] Furthermore, the outer casing is made of high-quality PSU material, and the pins are made of copper material with gold plating.

[0010] Furthermore, the side wall of the connector is provided with a through hole that matches the bolt and communicates with the groove, and the protruding side wall is provided with a threaded hole that matches the bolt.

[0011] The beneficial effects of this utility model are:

[0012] Before insertion, align the protrusions with the grooves one by one, ensuring that the grooves with limit rails correspond to the protrusions with limit slots to prevent misalignment and damage to the connector. During insertion, fully insert the socket into the housing and insert the pins into the core. At this point, the top of the housing should be flush with the top of the outer shell, and the protrusion should be fully inserted into the groove. The threaded hole and the through hole should be connected. Tighten the bolt into the threaded hole to lock the protrusion in the groove, thus locking the connector and socket together. The lock is more secure and cannot be pulled out even with force, effectively preventing the connector and socket from loosening or falling off. Attached Figure Description

It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0020] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] According to the appendix Figure 1 , 2 As shown: This utility model provides a connector to prevent mis-plugging: including a connector 1 and a socket 2. The socket 2 includes a housing 10 and a core 11 placed inside the housing 10. The connector 1 includes a housing 9, a sleeve 3 disposed at the bottom of the housing 9 and inserted into the socket 2, and a pin 12 placed inside the sleeve 3 and matching the core 11. The sleeve 3 is inserted into the housing 10, and the pin is inserted into the core 11, so that the connector 1 and the socket 2 can be connected. The housing 9 is made of high-quality PSU material, which has excellent heat resistance, chemical corrosion resistance, anti-aging, and durability. The pin 12 is made of copper material with gold plating. Using copper pins with gold plating provides strong conductivity, corrosion resistance, oxidation resistance, long service life, and stable transmission.

[0022] As per the instruction manual Figure 1 , 3 As shown in Figure 4: The top edge of the connector 2 is provided with multiple protrusions 4, and the bottom of the housing 9 is provided with multiple grooves 5 that are located outside the plug tube 3 and match the protrusions 4. One of the protrusions 4 has symmetrical limiting grooves 6 on both sides, and one of the grooves 5 has a limiting rail 7 that matches the limiting groove 6 on its inner side wall. The protrusions 4 are rectangular, and the edges of the protrusions 4 are rounded. Before insertion, the protrusions 4 and grooves 5 are matched one by one to ensure that the grooves 5 with limiting rails 7 correspond to the protrusions 4 with limiting grooves 6, so as to avoid misalignment and misplacing errors, and effectively avoid misinsertion and damage to the connector.

[0023] As per the instruction manual Figure 3 , 4 As shown: Multiple protrusions 4 are triangularly distributed on the top of the connector 2. The connector 1 is threaded with a bolt 8 for locking the protrusions 4 into the groove 5. The side wall of the connector 1 is provided with a through hole that matches the bolt 8 and communicates with the groove 5. The side wall of the protrusion 4 is provided with a threaded hole 13 that matches the bolt 8. After the protrusion 4 is inserted into the groove 5, the threaded hole 13 communicates with the through hole. By screwing the bolt 8 into the threaded hole 13, the protrusion 4 can be locked in the groove 5.

[0024] The principle of this utility model

[0025] Before use, align the protrusions 4 and grooves 5 one-to-one, ensuring that the groove 5 with the limit rail 7 corresponds to the protrusion 4 with the limit groove 6 to avoid misalignment and damage to the connector. During insertion, insert the sleeve 3 into the housing 10 and insert the pin into the core 11 to connect the connector 1 and the socket 2. After the sleeve 3 is fully inserted into the housing 10, the top of the housing 10 fits against the top of the outer shell 9, and the protrusion 4 is fully inserted into the groove 5. At this time, the threaded hole 13 is connected to the through hole. Tighten the screw 8 into the threaded hole 13 to lock the protrusion 4 in the groove 5, thus locking the connector 1 and the socket 2 together. Compared with the traditional threaded connection and bayonet connection, the locking is more secure and cannot be pulled out by force, effectively preventing the connector 1 and the socket 2 from loosening and falling off.

[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
