Description

Technical Field

[0001] The present application relates to the field of connectors, and in particular to a connector male terminal. Background Art

[0002] At present, with the increasing requirements of various industries for energy conservation and environmental protection and the increasingly strong demand for lightweight in aerospace, communications, automobiles, consumer electronics and other fields, connector components must also achieve weight reduction while ensuring stable performance improvement, so as to reduce costs while making inertia smaller and more resistant to vibration.

[0003] The connector is usually composed of a male terminal and a female terminal, wherein the male terminal includes a sheath and a pin disposed inside the sheath. Usually, a spring is disposed on the pin and fixed inside the sheath by the spring. However, after long-term use, the spring loses its elasticity due to aging, which causes the pin to loosen, thus affecting the normal use of the connector. Utility Model Content

[0007] The pin is also provided with a barb point, and the inner wall of the socket is provided with a limit platform, and the limit platform cooperates with the barb point to limit the axial displacement of the pin in the socket.

[0008] By adopting the above technical solution and utilizing the matching relationship between the barbed clamping point and the limit platform, the position of the pin in the socket is stabilized, effectively solving the problem of loose pins caused by aging or loss of elasticity of the spring piece, and significantly improving the stability and durability of the connector.

[0009] Preferably, the pins and the sockets are provided in plurality, and an empty slot is provided on the fixing plate between two adjacent sockets, and the barb clamping point extends into the empty slot.

[0010] By adopting the above technical solution, the setting of the empty slot can reduce the mass of the connector, and at the same time, the barb card point can be pushed through the empty slot, thereby facilitating the removal of the pin and thus facilitating the maintenance of the pin.

[0011] Preferably, the fixing plate divides the interior of the sheath into a front end area and a rear end area; the insertion pin includes a head portion located in the front end area, a middle portion located in the insertion hole, and a tail portion located in the rear end area.

[0013] Preferably, the rear end area is filled with waterproof glue.

[0014] By adopting the above technical solutions, the waterproof glue can significantly enhance the waterproof performance of the connector, thus providing more reliable performance in humid or underwater environments. At the same time, the waterproof glue can seal the rear end area of the sheath and further fix the pin, thereby improving the stability of the pin.

[0015] Preferably, a connecting clip is provided at the tail end of the pin. Anti-slip patterns are provided on the clamping surface of the connecting clip, and the connecting clip is used to clamp and fix the wire.

[0016] By adopting the above technical solutions, this structure makes the connection between the wire and the pin more stable. The waterproof glue can also fix the connection between the connecting clip and the wire, reducing problems such as poor contact or wire breakage caused by external forces.

[0017] Preferably, a partition board is further provided on the fixing plate, and the partition board is located between the tails of two adjacent pins.

[0018] By adopting the above technical solutions, the partition board can separate different pins, thus avoiding the phenomenon of miscontact, effectively preventing interference between adjacent pins, and improving the electrical performance of the connector.

[0019] Preferably, a waterproof sealing ring is further provided on the periphery of the sheath.

[0020] By adopting the above technical solutions, when the male terminal and the female terminal are engaged, the female terminal can be sleeved on the periphery of the male terminal, and the waterproof sealing ring is located in the gap between the male terminal and the female terminal, thereby achieving waterproofing between the male terminal and the female terminal.

[0021] Preferably, a locking buckle is provided on the outer wall of the sheath.

[0022] By adopting the above technical solutions, the locking buckle is used to cooperate with the female terminal of the connector. The design of the locking buckle makes the connection between the male terminal and the female terminal more convenient and stable.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] A barbed clamping point 31 is arranged on the outer wall of the pin 3, and a limiting platform 22 is arranged on the inner wall of the socket 21. When the pin 3 is inserted into the socket 21, the limiting platform 22 cooperates with the barbed clamping point 31 to limit the axial displacement of the pin 3 in the socket 21, ensuring that the pin 3 does not loosen during use.

[0032] Specifically, multiple insertion pins 3 and jacks 21 can be provided and are arranged in one-to-one correspondence. To further increase stability and reduce weight, the fixing plate 2 between adjacent two jacks 21 can be provided with an empty groove 23, and the empty groove 23 communicates with the adjacent two jacks 21, so that the barb clamping point 31 can extend into the empty groove 23. On the one hand, it can reduce the mass of the connector, and on the other hand, it can push the barb clamping point 31 through the empty groove 23, thus facilitating the disassembly of the insertion pin 3 and facilitating the maintenance of the insertion pin 3.

[0033] The rear end area is filled with waterproof glue, and the rear end area of the sheath 1 can be integrally open, so as to inject waterproof glue into the rear end area, thereby filling the entire rear end area to provide a waterproof function, and the waterproof glue can also seal the rear end area of the sheath 1 and further fix the insertion pin 3, thereby improving the stability of the insertion pin 3.

[0034] A connecting clip 32 is further provided at the tail of the insertion pin 3, and the connecting clip 32 can be used to clamp and fix the wire to prevent the wire from loosening or falling off during use. Further, anti-slip patterns can be provided on the clamping surface of the connecting clip 32 to enhance the stability of clamping.

[0035] To prevent electrical interference between adjacent insertion pins 3 and improve the electrical performance of the connector, an isolation plate 24 can also be provided on the fixing plate 2 and placed between the tails of adjacent two insertion pins 3, so as to prevent contact between the insertion pins 3 and adjacent wires from causing short circuits or other problems.

[0036] To enhance the waterproof ability, a waterproof sealing ring 4 can be provided on the circumferential side of the sheath 1. Preferably, the material of the waterproof sealing ring 4 is rubber, because this material has good elasticity and waterproof performance, enabling the connector to work properly in a humid or underwater environment.

[0037] Finally, a lock catch 5 can be provided on the outer wall of the sheath 1 for firmly mating and connecting with the female terminal of the connector. This design can prevent the terminal from loosening or falling off due to external force.

[0038] In this embodiment, the male terminal of the connector realizes the stable fixation of the insertion pin 3 in the jack 21 through the stable cooperation of the barb clamping point 31 and the limiting platform 22, the lightweight design of the empty groove 23, the waterproof injection glue treatment of the rear end area, the firm clamping of the connecting clip 32, the electrical interference protection of the isolation plate 24, the addition of the waterproof sealing ring 4 and the stable connection of the lock catch 5 of the sheath 1, and ensures the miniaturization, lightweight and high waterproof performance of the connector, thereby improving the stability and reliability of the connector, especially the durability in harsh environments.
