Description
Technical Field
[0001] This utility model relates to the field of connector technology, specifically a high-voltage waterproof connector structure for connecting transducers. Background Technology
[0002] Industrial connectors are primarily used for transmitting and controlling electrical signals, as well as for power connections between electronic and electrical equipment. They connect and disconnect circuits through the mating and disassembly of the connector plug and socket. Connectors are required to reliably conduct circuits, transmit information, and perform specific functions under various environmental conditions; their reliability directly affects the reliable operation of equipment, products, and other engineering systems.
[0003] Traditional industrial connectors improve safety and reliability by increasing the electrical clearance, the shortest air distance between two conductive parts. Increasing the electrical clearance reduces the electric field strength, preventing air ionization and arcing under high voltage. Traditional industrial connectors typically increase the electrical clearance by increasing the connector size or reducing the pin size. Insulating sleeves are used at the solder ends to achieve high withstand voltage between pins and between pins and the metal shell; waterproofing is achieved through the sealing effect of waterproof rings. However, the disadvantages of these connection methods are: the current carrying capacity after male and female solder wire assembly is relatively small, and the need for sleeves at the solder ends increases the connector size; the waterproofing measure relies solely on the sealing effect of the sealing ring, resulting in poor waterproofing performance.

The female connector 1 includes a first outer shell 11 and a female core 12 inserted into the inner cavity of the first outer shell 11. One end face of the female core 12 has multiple first partitions 121 evenly distributed in a divergent pattern, and a female pin 122 is disposed between adjacent first partitions 121. One end of the female core 12 with the first partitions 121 and the female pin 122 extends out of the first outer shell 11. The male connector 2 includes a second outer shell 21 connected to the first outer shell 11 and a male core 22 inserted into the second outer shell 21. One end of the male core 22 is connected to one end of the female core 12, and the end face of the male core 22 away from the female core 12 has multiple second partitions 221 evenly distributed in a divergent pattern. A male pin 222 is provided between two adjacent second partitions 221, and a rubber sleeve 223 is provided around the outer periphery of the male rubber core 22, surrounding the second partitions 221 and the male pin 222; please refer to Figure 3 A waterproof eaves structure 3 is provided at the connection between the first outer shell 11 and the second outer shell 21.

[0033] The male connector 2 includes a wire clamp 23 and a fixing sleeve 24. One end of the wire clamp 23 is connected to the fixing sleeve 24. The fixing sleeve 24 is fitted around the outer periphery of the rubber sleeve 223. The outer peripheral wall of the fixing sleeve 24 abuts against the inner wall of the second outer shell 21. The wire clamp 23 can fix the cable passing through the male connector 2. In this embodiment, the fixing sleeve 24 is composed of two semi-circular pieces spliced together.

Similarly, during assembly, the cooperation between the second locking protrusion 213 and the second locking position, the third locking protrusion 225 and the third locking position, and the fourth locking protrusion 241 and the fourth locking position prevent relative rotation between the second outer shell 21 and the first outer shell 11, the fixing sleeve 24 and the male core 22, and the fixing sleeve 24 and the second outer shell 21, making the structural connection more stable.
