[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4The utility model provides an anti-oxidation wire harness terminal 1, comprising a wire harness terminal 1 and a metal terminal 2, a connecting portion 3 is integrally formed on one side of the metal terminal 2, a chamfered portion 4 is arranged on the side of the connecting portion 3, an outer protective tube 5 is slidably arranged on the surface of the wire harness terminal 1, a sealing mechanism is arranged on the outer protective tube 5, the sealing mechanism comprises a sealing seat 6 and a baffle 7, the sealing seat 6 is fixedly arranged at one end of the outer protective tube 5, two baffles 7 are arranged, the two baffles 7 are rotatably arranged on the inner wall of the sealing seat 6, one ends of the two baffles 7 are in contact with each other, a fixing mechanism is arranged between the baffle 7 and the chamfered portion 4, the sealing mechanism also comprises a receiving groove 8 and a sealing ring 9, the receiving groove 8 is arranged at one end of the outer protective tube 5 away from the sealing seat 6, the sealing ring 9 is embedded in the receiving groove 8 and is sleeved on the surface of the wire harness terminal 1.

[0022] See also Figure 1 , 2 and 3, since one end of the sealing seat 6 is an open structure, in the initial state, the two baffles 7 are in a closed state, the opening structure of the sealing seat 6 can be shielded by the baffles 7, and since one end of the two baffles 7 is in contact with each other, there is static friction, Figure 1 The baffle 7 located at the bottom will not open under the action of gravity. The enclosed space formed by the wiring harness end 1, the outer protective tube 5 and the two baffles 7 can accommodate the metal end 2 and isolate it from the external gas, thereby achieving the purpose of anti-oxidation. When the metal end 2 is needed, it is only necessary to pull the outer protective tube 5 on the surface of the wiring harness end 1 so that the outer protective tube 5 drives the baffle 7 to move toward the direction close to the wiring harness end 1. The metal end 2 can push the two baffles 7 open. At this time, the baffle 7 can rotate on the inner wall of the sealing seat 6, so that the metal end 2 is exposed from the enclosed space for connection with other devices.

[0023] The fixing mechanism includes a groove 10 and a block 11. The block 11 is obliquely arranged on the surface of the baffle 7. The groove 10 is arranged on the surface of the inclined portion 4. The inclination angle of the block 11 to the horizontal plane is equal to the inclination angle of the inclined portion 4 to the horizontal plane.

[0024] See also Figure 2 When the metal end 2 is needed, the metal end 2 will move out of the outer protective tube 5, and the baffle 7 will rotate on the inner wall of the sealing seat 6 after being squeezed by the metal end 2. When the outer protective tube 5 drives the sealing seat 6 to move to the inclined portion 4, the inclined portion 4 can squeeze the baffle 7 again and rotate it. The rotated baffle 7 can just drive the bottom of the block 11 to be parallel to the horizontal plane. At this time, the outer protective tube 5 continues to be pushed, and the outer protective tube 5 can drive the block 11 to extend into the groove 10 through the sealing seat 6 and the baffle 7, thereby realizing the fixed connection between the baffle 7 and the inclined portion 4, so that the metal end 2 can be connected to other devices by holding the baffle 7 when in use.

[0025] It should be noted that the connection between the block 11 and the groove 10 can be achieved through static friction, or protrusions and grooves can be provided on the surfaces of the block 11 and the groove 10 to achieve a fixed connection between the block 11 and the groove 10 .

[0026] The outer protective tube 5 is composed of a flexible silicone tube 12, a hard support tube 13 and an insulating plastic tube 14. The surface of the flexible silicone tube 12 is sleeved with the hard support tube 13, and the surface of the hard support tube 13 is sleeved with the insulating plastic tube 14. The sealing ring 9 is arranged on the inner wall of the hard support tube 13 and contacts the surface of the flexible silicone tube 12.

[0027] See also Figure 4 Specifically, the flexible silicone tube 12 can increase the sliding friction between the wire harness end 1, thereby preventing the outer protective tube 5 from moving without reason during transportation or movement. The hard support tube 13 can increase the overall mechanical strength of the outer protective tube 5 to prevent deformation during processing or transportation. The insulating plastic tube 14 can insulate the outer protective tube 5 as a whole to facilitate the normal use of the metal end 2.

[0028] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
