As shown in fig. 1 and fig. 2, the present embodiment discloses a connector structure for electronic products, which includes a first connector body 1 and a second connector body 2. The first connector body 1 is cylindrical, the axis of the first connector body is horizontal, and the outer wall of the first connector body 1, close to the end portion of the first connector body, is provided with a first external thread 11. Referring to fig. 3, the connector body 1 is hollow and is fixed with a pin base 12. The first pin base 12 is rectangular and made of insulating material, and the first pin base 12 is fixed with a jack 221. The second connector body 2 is cylindrical, the axis of the second connector body is superposed with the axis of the first connector body 1, and the outer wall of the second connector body 2 is provided with a second external thread 21 at a position close to the end part of the second connector body. The second connector body 2 is hollow and fixed with a second pin base 22. The second pin base 22 is rectangular and made of insulating material, and the second pin base 22 is fixed with a pin 121 capable of being inserted into the socket 221.

As shown in fig. 3, a first locking nut 3 is sleeved on a second connector body 2, the first locking nut 3 is in a circular ring shape, internal threads are arranged in the first locking nut 3, the first external threads 11 and the second external threads 21 are in threaded connection, when the first connector body 1 and the second connector body 2 need to be connected, a worker only needs to align one end of the first connector body 1, which is provided with the first external threads 11, with one end of the second connector body 2, which is provided with the second external threads 21, then insert the insertion hole 221 into the insertion pin 121, and simultaneously screw the first locking nut 3 to one side of the first external threads 11 until the left side of the first locking nut 3 is aligned with the left side of the first external threads 11.

As shown in fig. 1, the outer arc surface of the first lock nut 3 is roughened by polishing, so that the friction coefficient of the surface of the first lock nut 3 is increased, and the friction between the first lock nut 3 and the hand of the worker is increased, thereby facilitating the worker to screw the first lock nut 3.

As shown in fig. 4, a sealing assembly 4 is mounted on the first lock nut 3 for maintaining the sealing property of the connection between the first connector body 1 and the second connector body 2, and the sealing assembly 4 includes an arc-shaped elastic pressing strip 41, a rubber sealing ring 42, a second lock nut 43 and a sealing tape 44. The cross section that arc elasticity compressed tightly strip 41 is the arc, and its length direction is parallel with the axis direction of connector body 1, adopts to have elastic material to make, like plastics, mild steel strip etc. the one end that arc elasticity compressed tightly strip 41 is close to two 21 one ends of external screw thread with lock nut 3 fixed, and arc elasticity compressed tightly strip 41 and keeps away from connector body 1 one side has seted up external screw thread three 411 on the surface. Rubber seal 42 is the ring form, and its axis coincides with the axis of connector body 1, and rubber seal 42 adopts rubber materials to make, has good elasticity performance, and rubber seal 42's lateral wall compresses tightly the laminating of the inboard arc surface of strip 41 and fixes with arc elasticity, and rubber seal 42's inside wall and the cooperation of sliding of the lateral wall of connector body 1. The axis of the second locking nut 43 coincides with the axis of the first connector body 1, the second locking nut 43 is in threaded connection with the third external thread 411, and an annular groove 431 is formed in one end, close to the arc-shaped elastic pressing strip 41, of the second locking nut 43. The axis of the annular groove 431 coincides with the axis of the first connector body 1, and the diameter of the annular groove 431 is linearly decreased from the arc-shaped elastic pressing strip 41 to the side away from the arc-shaped elastic pressing strip 41, so that a worker can conveniently screw the second lock nut 43 onto the arc-shaped elastic pressing strip 41. The sealing tape 44 is wound on the second external thread 21, so that when the first locking nut 3 is screwed with the second external thread 21, the sealing tape 44 is filled in a gap between the first locking nut 3 and the second external thread 21, thereby maintaining the sealing performance of the connection between the first locking nut 3 and the second connector body 2 and preventing water from entering the second connector body 2 from the connection between the second connector body 2 and the first locking nut 3 (see fig. 2 as a result).

As shown in fig. 1, the second locking nut 43 is sleeved with a regular hexagon block 432 fixed thereto, so that a worker can hold the regular hexagon block 432 when screwing the second locking nut 43, and difficulty in screwing the second locking nut 43 by the worker is reduced.

The working principle of the embodiment is as follows: when connecting two connectors, the staff only need with connector body one 1 have the one end of external screw thread one 11 with connector body two 2 have the one end of external screw thread two 21 to correspond, rotatory lock nut one 3 afterwards for lock nut one 3 with external screw thread one 11 and the equal threaded connection of external screw thread two 21 can. At this time, the sealing tape 44 is filled to fill the gap between the first locking nut 3 and the second external thread 21, so that the sealing performance of the connection between the first locking nut 3 and the second connector body 2 is maintained, and water is prevented from entering the second connector body 2 from the connection position between the second connector body 2 and the first locking nut 3. In order to avoid water from entering the connector body I1 from the connector body I1 and the locking nut I3, the staff only need to compress tightly the arc-shaped elastic pressing strip 41 and simultaneously screw the locking nut II 43 so that the locking nut II 43 is screwed with the arc-shaped elastic pressing strip 41, at the moment, the arc-shaped elastic pressing strip 41 extrudes the rubber sealing ring 42 so that the inner side arc surface of the rubber sealing ring 42 is compressed tightly with the outer side arc surface of the connector body I1, and therefore water is prevented from entering the connector body I1 from the joint of the connector body I1 and the locking nut I3.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
