Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a male connector that prevents mis-mating. Background Technology

[0002] In fields such as electronic equipment, industrial control, and communication equipment, male connectors are key components for enabling the transmission of electrical signals or power between devices.

[0003] Existing male connectors lack anti-mismating structures, making it difficult to prevent mismating. Mismating not only leads to signal transmission interruption and equipment malfunction, but can also damage internal conductive components or device interfaces, resulting in economic losses. Therefore, we have introduced a mismating-proof male connector. Utility Model Content

[0004] The main objective of this invention is to provide a male connector that prevents mis-insertion, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A male connector designed to prevent mis-mating includes a connector and a fastener;

[0007] The connector includes a plug-in base, a fixing block, a protrusion, a plug hole, a pin, a slot, a T-shaped plug-in block, a first external thread groove, and a second external thread groove;

[0008] The fasteners include fastening nuts and rubber rings;

[0009] The fixing block is located in the middle of the connector, the protrusion is located at the front end of the connector, the insertion hole is provided through the connector, the pin is located in the insertion hole, the slot is opened at the front end of the connector, the T-shaped connector is located on the rear end face of the connector, the first external thread groove is located on the front outer side of the fixing block, the second external thread groove is located on the rear outer side of the fixing block, the rubber ring is sleeved in the protrusion, and the fastening nut is connected to the fixing block.

[0010] Preferably, the shape of the T-shaped plug block matches the corresponding slot of the female connector to achieve anti-misinsertion positioning.

[0011] By adopting the above technical solution, the unique compatibility between the T-type connector and the corresponding slot of the female connector is utilized to prevent the insertion of incorrect female connectors, thereby structurally eliminating the risk of misinsertion and ensuring the accuracy of equipment connection.

[0012] Preferably, the pins and sockets are arranged in a one-to-one correspondence, and the two ends of the pins extend to the two ends of the socket respectively.

[0013] By adopting the above technical solution, stable installation of the pins can be achieved, ensuring the stability of electrical signal transmission.

[0014] Preferably, the rubber ring is completely fitted inside the protrusion.

[0015] By adopting the above technical solution, a stable installation space is provided for the rubber ring.

[0016] Preferably, the fixing block and the plug-in seat are an integral structure, the fastening nut is connected to the first external thread groove of the fixing block through the internal thread, and the rear end of the fastening nut abuts against the outer surface of the rubber ring.

[0017] By adopting the above technical solution: the integrated structure improves the overall strength of the connector, and the fastening nut and the first external thread groove can press the rubber ring together to keep the rubber ring in a stable state and prevent it from loosening during use.

[0018] Preferably, the number of T-shaped connectors is the same as the number of card slots.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In this invention, by setting a T-shaped plug and a slot on the plug socket, a uniquely compatible docking structure is formed, which effectively avoids mis-plugging operations and ensures the accuracy of equipment connection. The reasonable layout of the pins and sockets ensures stable signal transmission. The overall structure is compact and solves the problem of high mis-plugging risk in existing connectors.
