Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a waterproof female connector. Background Technology

[0002] In fields such as electronic equipment, industrial control, and outdoor communication, female connectors are the core components for transmitting electrical signals or power, and their applications cover multiple fields such as consumer electronics, automotive electronics, smart devices, and outdoor engineering equipment.

[0003] However, existing female connectors lack a sealing structure, making it difficult to prevent moisture from seeping in through the gaps between the connector and the external structure, as well as the assembly seams of internal components. This easily leads to oxidation and corrosion of internal conductive parts such as pins, causing signal transmission interruptions, short circuits, and other malfunctions, severely affecting the normal operation and stability of the equipment and failing to meet the long-term use requirements in complex and harsh environments. Therefore, we have introduced a waterproof female connector. Utility Model Content

[0004] The main objective of this invention is to provide a waterproof female connector that 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 waterproof female connector includes a connector, a connecting assembly, a first waterproof rubber ring, a second waterproof rubber ring, a first rubber ring, and a second rubber ring;

[0007] The connector includes a connecting housing and an internal threaded groove, and the connecting housing has a groove.

[0008] The connecting assembly includes a positioning seat, a pin, a socket, a T-shaped slot, a sleeve, and a protrusion;

[0009] The internal thread groove is located on the inner side of the connecting housing, the first waterproof rubber ring is located in the groove of the connecting housing, the positioning seat is connected to the connecting housing, the pin is located in the positioning seat, the insertion hole is provided through the positioning seat, the second waterproof rubber ring is located at the bottom of the positioning seat, the T-shaped slot and the sleeve slot are both opened on the positioning seat, the first rubber ring and the second rubber ring are both sleeved in the sleeve slot of the positioning seat, and the protrusion is located on the outer side of the positioning seat.

[0010] Preferably, the groove of the connecting shell is circumferentially opened along its inner wall, the first waterproof rubber ring is adapted to the groove and is completely embedded in the groove, and the inner side of the first waterproof rubber ring is fitted and sealed to the outer side of the positioning seat.

[0011] By adopting the above technical solution, the first radial seal between the connecting shell and the positioning seat is achieved, preventing moisture from entering through the gap between the two.

[0012] Preferably, the protrusion of the positioning seat corresponds to the internal thread groove of the connecting housing, and the positioning seat can be detachably connected to the inside of the connecting housing through the cooperation of the protrusion and the internal thread groove.

[0013] By adopting the above technical solution, the positioning seat can be easily disassembled and assembled, and the internal pins can be easily maintained or replaced, thus improving ease of use.

[0014] Preferably, the pins are evenly distributed along the axial direction of the positioning seat, and the two ends of the pins extend to the outer sides of the two ends of the positioning seat, respectively. The insertion holes correspond one-to-one with the pins and are sleeved on the outer side of the pins, with a gap between the insertion holes and the pins.

[0015] By adopting the above technical solutions, the pins are evenly distributed, facilitating connection with the male connector. The sockets protect the pins from deformation caused by external forces, and the gap design ensures the stability of signal transmission.

[0016] Preferably, the second waterproof rubber ring completely covers the bottom end face of the positioning seat, the edge of the second waterproof rubber ring is tightly fitted with the inner wall of the connecting shell, and the T-shaped slots of the positioning seat are evenly distributed along its circumference for positioning and engagement with the external structure.

[0017] By adopting the above technical solution, axial sealing of the bottom of the positioning seat is achieved to prevent moisture from entering from the bottom, and the T-shaped slot improves the positioning accuracy and stability of the connector connection with the external structure.

[0018] Preferably, the sleeve grooves are spaced apart in two sets on the positioning seat, and the first rubber ring and the second rubber ring are respectively fitted into the two sets of sleeve grooves. The outer sides of the first rubber ring and the second rubber ring are both fitted and sealed to the inner wall of the connecting shell.

[0019] By adopting the above technical solution, a double radial seal is formed, which further enhances the waterproof effect. Even if one of the sealing structures fails, the other can still play a protective role, thus improving product reliability.

[0020] Preferably, the top of the positioning seat is flush with the top end face of the connecting shell, the height of the first waterproof rubber ring is adapted to the depth of the groove, and the outer side of the first waterproof rubber ring is flush with the inner wall of the connecting shell.

[0021] By adopting the above technical solution, the overall structure of the connector is kept flat, avoiding protruding parts from affecting the mating with the male head, while ensuring that the first waterproof rubber ring can fully perform its sealing function without affecting the assembly accuracy.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] In this invention, the T-shaped slot of the positioning seat achieves precise positioning with the external structure. After the external male connector is inserted, it contacts the pin inside the positioning seat. The socket provides protection and positioning for the pin, ensuring stable transmission of electrical signals or power. At the same time, the first waterproof rubber ring in the groove of the connecting shell, the first rubber ring and the second rubber ring in the groove of the positioning seat, and the second waterproof rubber ring at the bottom of the positioning seat form a triple sealing structure, which comprehensively blocks moisture and dust from different dimensions, effectively preventing failure of internal conductive components. The positioning seat is securely and detachably engaged with the internal threaded groove of the connecting shell through the protrusion, ensuring that the overall structure does not loosen during use and facilitating later maintenance, greatly improving the waterproof sealing performance, connection stability, and ease of use of the connector.
