However, the sealing effect of this elastic sealing ring is not good.
Moreover, in order to achieve radial extrusion, the outer diameter of the elastic sealing ring must be larger than the diameter of the terminal socket, which makes it difficult for the elastic sealing ring sleeved on the conductive terminal to be inserted into the terminal socket, and will cause serious friction with the inner wall of the terminal socket. Friction, if the conductive terminal needs to be inserted and pulled out repeatedly, it will cause damage to the elastic sealing ring and cause the seal to fail

The invention discloses a connector, which comprises an insulating body, at least one conductive terminal and at least one elastic sealing element, wherein the insulating body is provided with at least one terminal jack; the at least one conductive terminal is respectively inserted into the at least one terminal jack; and the at least one elastic sealing element is respectively sleeved on the at least one conductive terminal. Each elastic sealing element comprises an outer ring part and an inner ring part, wherein the inner ring part is sleeved on the conductive terminal, and the conductive terminal expands the inner ring part outwards along the radial direction of the conductive terminal, so that the inner ring part and the conductive terminal are in close contact; and an annular positioning protrusion is formed on the inner wall of each terminal jack. The connector further comprises a pushing and pressing piece, wherein the pushing and pressing piece pushes and presses the outer ring part on the annular positioning protrusions in the axial direction of the conductive terminals so as to enable the outer ring part to make close contact with the annular positioning protrusions. According to the invention, the sealing interface of the inner ring part and the outer ring part of the elastic sealing element is not affected when the conductive terminal moves, so that the sealing performance is improved. In addition, radial sealing and axial sealing are achieved through the inner ring part and the outer ring part respectively, and the correlation degree between the inner ring part and the outer ring part is small.
Description
technical field [0001] The invention relates to a connector. Background technique [0002] In the prior art, to realize the sealing between the terminal insertion hole of the connector and the conductive terminal, a common elastic sealing ring is usually used. The elastic sealing ring is squeezed between the inner wall of the terminal insertion hole and the conductive terminal in the radial direction. However, the sealing effect of this elastic sealing ring is not good. Moreover, in order to achieve radial extrusion, the outer diameter of the elastic sealing ring must be larger than the diameter of the terminal socket, which makes it difficult for the elastic sealing ring sleeved on the conductive terminal to be inserted into the terminal socket, and will cause serious friction with the inner wall of the terminal socket. Friction, if the conductive terminal needs to be plugged and pulled repeatedly, it will cause damage to the elastic sealing ring and cause the seal to fai...
