Detailed Description

In order to achieve the purpose, the utility model adopts the technical scheme that: referring to fig. 1 to 4, the electric connector with the self-return sealing structure comprises a male plug 1 and a female plug 2 which are matched and plugged with each other, and a sealing ring 3 which is matched and connected with the male plug (1) and the female plug (2). The shells of the male plug (1) and the female plug (2) are provided with a female lock catch and a male lock catch (13, 23) which are matched and buckled with each other. In order to reduce the production cost of the female socket shell, a sealing ring groove is not arranged on the female socket shell, and the sealing ring 3 is arranged on the female plug plugging part 11.

Because the sealing ring 3 has no corresponding sealing ring groove for limiting, the sealing ring 3 can move along with the male plug 1 when being pulled out in the process of plugging and unplugging the male plug and the female plug to cause dislocation, and when the male plug and the female plug are plugged again, the plugging and the sealing of the male plug and the female plug are influenced. In order to enable the sealing ring 3 to automatically return, N jacking blocks 11 which are matched with the sealing ring 3 and press the sealing ring 3 are arranged in the male plug 1. The top blocks are columnar, and the top blocks 11 are uniformly distributed on the inner cavity wall 22 of the male plug 1. When the male plug is plugged, the top block 11 is in contact with the end part at the side of the sealing ring 3, the sealing ring 3 is pushed to the inner end of the shell plugging part of the female plug 2, and the resetting of the sealing ring 3 is realized. The sealing ring 3 adopts a wide edge ring, so that the ejector block is convenient to push and return, and is not easy to twist. The inner ring and the outer ring of the sealing ring 3 are respectively provided with a sealing ring bulge 31 to realize the sealing between the male plug and the female plug.

In order to prevent short circuit between adjacent electrodes when the male plug and the female plug are plugged, a micro short circuit prevention baffle 15 is arranged on the male plug 1, the micro short circuit prevention baffle 15 is not higher than the ejector block, and the micro short circuit prevention baffle 15 is arranged in the middle of the opposite plugging surface of the male plug 1 and used for separating the electrode columns. In order to support blind plugging, the plug-in end of the male plug 1 is provided with an anti-reverse plug-in 14, and the plug-in end of the female plug 2 is provided with a slot 22 matched with the anti-reverse plug-in. Preferably, the anti-reverse plug-in 14 is arranged in the middle of the opposite plug end of the male plug and is integrally formed with the micro short circuit prevention baffle 15, and the anti-reverse plug-in 14 is Y-shaped.

Compared with the prior art, the utility model has the beneficial effects that: the sealing ring groove is not arranged on the female plug shell, so that the structure is simplified, the die sinking manufacturing is facilitated, and the processing cost is saved; because N jacking blocks for pressing the sealing rings are uniformly distributed on the inner cavity wall 22 of the male plug, the periphery of the end wall of each sealing ring is uniformly contacted and stressed at local points, the sealing rings can be pushed without using large force, the sealing rings reset, and the male plug and the female plug are easily inserted.

It should be understood that the above examples are only for clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And such obvious variations or modifications which fall within the spirit of the utility model are intended to be covered by the scope of the present invention.
