Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a bayonet-type electrical connector. Background Technology

[0002] Electrical connectors are indispensable components in electronic devices, with increasingly widespread applications. Their forms and structures are incredibly diverse, varying depending on the application, frequency, power, and environment. In existing technology, electrical connectors mainly consist of a plug and a socket. The plug has a jack, and the socket has pins. Communication between the plug and socket occurs through the jack and the pins.

[0003] Patent document CN2021216990331 discloses a multi-point contact bayonet-type electrical connector, which includes a socket and a plug. The plug includes a plug housing, a connecting cap, a socket insulator, and a socket. Four slots are axially formed on the front wall of the socket, and the slots are evenly distributed circumferentially around the socket. A limiting spring mounting groove is provided on the front wall of the socket, and a limiting spring is installed in the limiting spring mounting groove. The socket includes a socket housing, pins, and pin insulator. In this invention, by evenly distributing four slots at the front end of the socket, the number of contact points is increased to four, increasing the contact surface and improving the elastic deformation capacity of the socket. The socket has good elasticity, making the electrical connector insertion and removal smooth. Simultaneously, in conjunction with the limiting spring, on the one hand, the limiting spring generates positive pressure on the pin, ensuring reliable contact between the pin and the socket; on the other hand, it limits the degree of elastic deformation of the socket.

[0004] In the case of a multi-point contact bayonet-type electrical connector with this configuration, the use of the plug housing, connecting cap, socket insulator, and socket can only increase the service life of the socket and pins. However, the process of fixing the two connectors together is cumbersome and time-consuming, resulting in inconvenience in use. Therefore, we propose a bayonet-type electrical connector to solve the above problems. Utility Model Content

[0005] To at least partially solve the aforementioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a bayonet-type electrical connector, comprising an A cable, an A connector, a B cable, and a B connector. One end of the A cable is connected to the A connector, and one end of the B cable is connected to the B connector. The A connector includes a housing, with a male pin connected to the inner surface of the housing, an A retainer connected to the outer surface of the housing, and an A retainer block connected to the surface of the A retainer. The B connector includes a support plate, with a female connector connected to the surface of the support plate, a B retainer connected to the surface of the support plate, and a B retainer block connected to the inner surface of the B retainer.

[0007] Furthermore, a protective sleeve (A sleeve) is attached to the surface of cable A, and a retaining clip (A housing) is located on the surface of the protective sleeve. The connector (A) is fixedly connected to the protective sleeve. A protective sleeve (B sleeve) is attached to the surface of cable B, and a retaining clip (B housing) is located on the surface of the protective sleeve. The connector (B connector) is fixedly connected to the protective sleeve. A sealing ring is attached to the surface of the outer casing.

[0008] Furthermore, the A cable includes a waterproof rubber tube, the inside of which is connected to a braided layer, the inside of which is connected to a flame-retardant strip, and the inside of which is connected to a conductor.

[0009] This utility model has the following beneficial effects:

[0010] This invention moves connector A and connector B towards the center, aligning the male pin with the female pin, connecting the outer shell and the support plate to achieve electrical connection at both ends. Then, the A-clamp on the surface of the A protective sleeve is moved towards the center, and simultaneously the B-clamp on the surface of the B protective sleeve is moved towards the center. The A-clamp passes through the middle of two adjacent B-clamps, and then the A-clamp is twisted to lock the A-clamp and B-clamps together. This design achieves convenient use and a wide range of applications, solving the problem of inconvenient operation.

[0011] This invention, by using a sealing ring, reduces the entry of water and oxygen from the gaps at the connection point between the male and female connectors, thereby increasing the sealing performance of the bayonet-type electrical connector.

[0012] This invention, by using protective sleeve A and protective sleeve B, can protect the connection between cable A and connector A and the connection between cable B and connector B from breakage, thereby increasing the service life of connectors A and B.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] Please see Figures 1-5As shown, this utility model is a bayonet-type electrical connector, including an A cable 1, an A connector 2, a B cable 3, and a B connector 4. One end of the A cable 1 is connected to the A connector 2, and one end of the B cable 3 is connected to the B connector 4. The A connector 2 includes a housing 21, with a male pin 22 connected to the inner surface of the housing 21, an A retainer 23 connected to the outer surface of the housing 21, and an A retainer block 24 connected to the surface of the A retainer 23.
