Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without making creative labor belong to the protection scope of the utility model.

[0047] With reference to Figures 1-3 An embodiment provided by the utility model: an electrical harness terminal sheath, including sheath 1, the inside of sheath 1 is uniformly provided with through hole 7, the inner wall of through hole 7 is slidably connected with terminal 14, the rear end of terminal 14 is rotatably connected with top rod 13, the rear surface of sheath 1 is slidably connected with flange 2, the front side of the bottom of flange 2 is fixedly connected with slide rail two 5, the inner wall of slide rail two 5 is rotatably connected with pivot 8, the surface of pivot 8 is fixedly connected with handle 6, the top end of handle 6 is fixedly connected with limit block 10, the rear side of flange 2 is fixedly connected with retaining member 3, the surface of terminal 14 is provided with limit mechanism 15;

[0048] By operating handle 6, pivot 8 can be driven to rotate in slide rail two 5, the top end of handle 6 is connected with limit block 10, limit block 10 cooperates with the corresponding groove 9 on sheath 1, the connection or separation of retaining member 3 and sheath 1 is controlled, flange 2 can provide certain support for sheath 1, which plays the role of stabilizing and protecting the harness terminal system, limit mechanism 15 provided on the surface of terminal 14 can ensure that terminal 14 remains stationary after installation, avoiding displacement of terminal 14 due to external force, thereby ensuring the stability of electrical system connection.

[0049] With reference to Figure 4 Limit mechanism 15 includes pin 1503, pin 1503 is fixedly connected between terminal 14, the surface of top rod 13 is provided with sliding groove 1501, pin 1503 is slidably connected between sliding groove 1501, pin 1503 is slidably connected with elastic ring 1502 on the surface, the surface of terminal 14 is fixedly connected with limit ring 1504;

[0050] The material of elastic ring 1502 adopts silicone rubber material, when terminal 14 is inserted into top rod 13, limit ring 1504 contacts the end face of elastic ring 1502, terminal 14 continues to advance, so that limit ring 1504 continuously compresses elastic ring 1502 to the designed stroke, at this time, rotating terminal 14 drives pin 1503 to move to the end locking position along sliding groove 1501, pin 1503 is driven by the elastic recovery force of elastic ring 1502 after being clamped into sliding groove 1501, axial pre-tightening force and radial holding force are generated, double locking is formed, thereby improving the pull-out resistance of the harness terminal.

[0051] With reference toFigure 4 The rear surface of the limiting ring 1504 is tightly fitted between the front surface of the elastic ring 1502 and the inner wall surface of the through hole 7, and the rear surface of the elastic ring 1502 is fixedly connected to the inner wall surface of the through hole 7;

[0052] In the limiting mechanism 15 of the terminal 14, the rear surface of the limiting ring 1504 is tightly fitted with the front surface of the elastic ring 1502 to form a stable contact relationship, and the rear surface of the elastic ring 1502 is fixedly connected to the inner wall surface of the through hole 7 by a clamping process.

[0054] Referring to Figure 3 The top rod 13 is threadedly connected to the retaining member 3, and the top rod 13 is slidingly connected to the inner wall of the through hole 7;

[0055] The threaded connection between the top rod 13 and the retaining member 3 makes the top rod 13 replaceable. While being stably connected to the retaining member 3, the outer surface of the top rod 13 forms a sliding connection with the inner wall of the through hole 7, allowing it to smoothly slide within the through hole 7.

[0056] Referring to Figure 2 A recess 9 is formed in the bottom of the sheath 1, and the limiting block 10 is slidingly connected to the inner wall of the recess 9. A recess 9 is formed in the bottom of the sheath 1, and the shape of the recess 9 is adapted to that of the limiting block 10. The limiting block 10 can smoothly slide between the inner walls of the recess 9. When the operating handle 6 drives the rotating shaft 8 to rotate, the limiting block 10 fixedly connected to the operating handle 6 rotates into the recess 9, thereby realizing the connection between the retaining member 3 and the sheath 1.

[0057] Referring to Figures 1-2The rear surface of the sheath 1 is attached to the front surface of the holder 3,

[0058] In the connection of the sheath 1 and the holder 3, the holder 3 is aligned with the rear side of the sheath 1 to attach them, and through the cooperation of the slide rail two 5, the rotating shaft 8, the rotating handle 6 and the limiting block 10 at the bottom of the flange 2, the stable connection of the sheath 1 and the holder 3 is realized, and the relative displacement of the sheath 1 due to external forces such as vibration and pulling in the use process is prevented.

[0059] Referring to Figure 3 The bottom of the rotating handle 6 is fixedly connected with the spring 12, and the bottom end of the spring 12 is fixedly connected with the inner wall bottom of the slide rail two 5. In the initial state, the spring 12 lifts the rotating handle 6 upward, so that the limiting block 10 enters the inside of the groove 9, and the connection state between the sheath 1 and the holder 3 is realized.

[0060] Working principle: when it is needed to separate the sheath 1 and the holder 3, since the rotating handle 6 is fixedly connected with the rotating shaft 8, the rotating shaft 8 is rotatably connected with the slide rail two 5, the slide rail two 5 is fixedly connected with the holder 3, and the limiting block 10 is fixedly connected with the top end of the rotating handle 6, by pulling the rotating handle 6 upward, the limiting block 10 can be rotated around the rotating shaft 8, so that the limiting block 10 is separated from the inside of the groove 9, the connection state between the holder 3 and the sheath 1 is released, and the integration between the sheath 1 and the holder 3 is unlocked, so that the disassembly of the sheath 1 is more rapid and convenient.

[0061] In terms of the fixation of the terminal 14, since the limiting ring 1504 is arranged on the surface of the terminal 14, after the top end of the terminal 14 enters the top rod 13, the elastic ring 1502 generates an elastic force under the pressure of the terminal 14, by rotating the terminal 14, the pin 1503 is located at the end of the sliding groove 1501, and the terminal 14 moves forward under the action of the elastic force of the elastic ring 1502, so that the pin 1503 is located at the front side of the sliding groove 1501. At this time, the elastic ring 1502 is always compressed by the terminal 14 to generate a radial holding force, so that the fastening and the anti-pulling ability of the wire harness terminal are improved.
