Description

Technical Field

[0001] The utility model relates to the field of connectors, and particularly to a BNC connector. Background Art

[0002] Connectors, as an important part of electronic devices and systems, are mainly used to connect and disconnect circuits or signals. They are used in, but not limited to, communication, aerospace, radio and television, monitoring systems, and electronic test equipment. In these fields, connectors are not only responsible for signal transmission but also ensure the stability and integrity of data. BNC connectors, as a type of connector, are particularly suitable for connecting radio frequency devices. With their simple, reliable, and easy-to-use characteristics, they have been widely used in fields such as communication, radio and television, and monitoring systems. BNC connectors are usually used to transmit high-frequency signals such as video signals, audio signals, and digital signals, providing a simple and reliable solution for signal transmission in these fields.

[0003] Existing BNC connectors are divided into male and female connectors. The BNC connector mainly includes parts such as BNC-T connectors, BNC barrel connectors, BNC cable connectors, and BNC terminators. BNC-T connectors are mainly used to connect computer network cards and cables in the network. BNC barrel connectors are used to connect two thin cables into a longer cable. BNC cable connectors are used to weld or screw onto the ends of cables. BNC terminators are used to prevent signals from reflecting back and causing interference after reaching the cable break.

[0004] However, although the structural design of existing BNC connectors is relatively mature, in some special usage scenarios, such as high-vibration and high-impact environments, their connection stability will be affected to a certain extent, and there is a risk of detachment or loosening. The existing connection structure is prone to loosening during use, resulting in poor connection stability. In addition, after long-term use, due to wear or loosening of the contact part, the connection performance may decline, reducing the connection tightness of the connector, and even causing poor contact, affecting the use effect of the connector. Summary of the Utility Model

[0005] The purpose of the present utility model is to solve the above defects and provide a BNC connector to solve the technical problems that the connector is prone to wear in a high-vibration environment, resulting in poor connection stability and affecting the stable connection and use of the connector as described in the above background art.

[0006] The purpose of the present utility model is achieved in the following way:

[0007] A BNC connector includes a housing. Plugging portions and connecting portions are respectively formed at two ends of the housing. A connecting hole is formed in the plugging portion. A contact member is connected in the connecting hole through an insulator. A jack is formed in the contact member. Oppositely distributed positioning protrusions are arranged on the outer surface of the plugging portion. A clamping member is snap-connected in the positioning protrusion through a clamping groove. A reset member is sleeved in the clamping member. The reset member can drive the clamping member to move radially along the plugging portion. A socketing groove is formed on the surface of the housing close to the plugging portion. A sealing washer is detachably socketed in the socketing groove. The sealing washer can rotate along the socketing groove. And oppositely distributed sealing plugs are arranged on the sealing washer. The sealing plugs extend towards the end of the plugging portion.

[0008] Further in the above description, the clamping groove is arranged in the positioning protrusion, and the clamping groove is in an inverted "T" shape. A guiding column is arranged in the clamping groove. The end of the guiding column extends towards the opening end of the clamping groove. The positioning protrusion is provided with the clamping groove so that the clamping member can be connected through the clamping groove, thereby further enhancing the plugging with the corresponding male BNC connector, improving the connection stability with the male BNC connector, and reducing the loosening and falling-off phenomenon of the connector.

[0009] Further in the above description, one end of the clamping member forms a connection end paired with the clamping groove. The connection end of the clamping member is press-fastened with the clamping groove. During use, a clamping groove paired with the clamping member is formed on the plugging end of the male BNC connector. When the connecting portion of the housing is fixed at the corresponding installation position, the clamping groove of the male BNC connector is paired with the positioning protrusion and moves along the arc-shaped clamping groove under rotation. When it moves to the end of the clamping groove, the clamping member extends towards the outside of the clamping groove under the reset of the reset member and contacts the outer surface of the male BNC connector, thereby further improving the connection stability and reliability with the male BNC connector.

[0010] Optionally, the clamping groove of the male BNC connector is a countersunk clamping groove. A stepped and conducting clamping groove is formed in the clamping groove so that the clamping member can be clamped and connected with the step in the clamping groove.

[0011] Further in the above description, the reset member is composed of a reset spring. One end of the reset member is sleeved with a guiding protrusion, and the other end of the reset member abuts against the connection end of the clamping member. Under the reset of the reset member, the clamping member can move towards...

[0012] Further in the above description, the sealing washer is socketed on the plugging portion and nested in the socketing groove. The plugging portion of the housing moves radially, so that the surface of the clamping member close to the positioning protrusion forms a clamping position with the positioning protrusion.

[0013] Further in the above description, an external thread is formed on the outer surface of the connecting portion. A wire sleeve is formed at the end of the connecting portion. A sheath is sleeved on the guiding sleeve.

[0014] Advantages of the present utility model: The clamping groove in the positioning protrusion is connected to the clamping member. When the positioning protrusion is connected to an external connecting member, the clamping member can move radially along the insertion part under the reset action of the reset member, so that the connector can be further kept in a stable position during the connection process through the clamping member, and is not easy to fall off or loosen, improving the convenience and reliability of use. The sealing gasket nested in the socket groove can improve the sealing performance when connected to an external connecting member, effectively preventing external impurities such as dust and moisture from entering the connector. When the sealing gasket can rotate along the socket groove, the sealing plug on the sealing gasket is in paired contact with the external connecting member, further enhancing the stability and firmness of the connection between the connector and the external connecting member, preventing accidental loosening, and improving the overall protection ability of the connector.
