[0036] This embodiment provides a protection device for a wire harness 4. Refer to Figures 1 to 5As shown, the wire harness 4 protection device includes a fixed plate 1, a movable plate 2 and a connecting member 3. The fixed plate 1 is provided with a first sliding groove 11 in a first direction, and a through hole 111 and a connecting hole 112 are formed at the bottom of the first sliding groove 11. The movable plate 2 is arranged on the fixed plate 1 and is slidably connected with the first sliding groove 11. The movable plate 2 is provided with a U-shaped groove 21 in the first direction, and the U-shaped groove 21 and the through hole 111 can jointly form a limiting clamping space. The relative sliding of the movable plate 2 with respect to the first sliding groove 11 can adjust the size of the limiting clamping space. The movable plate 2 is provided with a long hole 22 extending in the first direction, and the connecting member 3 passes through the long hole 22 and is fixedly connected with the connecting hole 112.
[0037] In this embodiment, the direction shown by a in the attached drawing is the first direction. The first direction may be the length direction of the fixed plate 1 and the movable plate 2.
[0038] In this embodiment, the limiting clamping space formed by the through hole 111 and the U-shaped groove 21 can allow the wire harness 4 to pass through and can limit and clamp the wire harness 4 to realize the fixation of the penetrated wire harness 4. When the movable plate 2 slides in place relative to the fixed plate 1, the connecting member 3 passes through the long hole 22 and is fixedly connected with the connecting hole 112, thereby realizing the fixation between the movable plate 2 and the fixed plate 1. It can be understood that the limiting clamping space is the communication area between the through hole 111 and the U-shaped groove 21, and is also the area for the wire harness 4 to pass through. The movable plate 2 is slidably connected with the first sliding groove 11. When the movable plate 2 slides relative to the first sliding groove 11, the relative displacement of the movable plate 2 and the fixed plate 1 can adjust the size of the limiting clamping space, so that different numbers of wire harnesses 4 can be passed through and fixed. There is no need to set multiple retaining coils of different sizes for replacement as in the prior art, effectively ensuring practicability and use compatibility, and reducing production and use costs. In addition, the size of the limiting clamping space is adjusted according to the number of penetrated wire harnesses 4, which can further eliminate gaps, prevent water vapor and dust from entering, and achieve a reliable dust-proof effect.
[0039] Specifically, the setting of the long hole 22 can provide a sliding avoidance space for the connecting member 3, so that the connecting member 3 can realize the sliding of the movable plate 2 without being removed from the connecting hole 112.

The resisting portion 12 and the first sliding groove 11 together form a plugging space, and the movable plate 2 is adapted to extend into the plugging space during the process of sliding relative to the first sliding groove 11. Specifically, the resisting portion 12 and the first sliding groove 11 are integrally formed. The end portion of the movable plate 2 extends into the plugging space, and the movable plate 2 abuts against the resisting portion 12, further ensuring the reliable and stable movement of the movable plate 2.
[0044] Specifically, the resisting portion 12 has a first limiting abutting surface 121. One end of the movable plate 2 facing the resisting portion 12 has an extending portion 23. The extending portion 23 can extend into the plugging space. A second limiting abutting surface 231 is formed between the extending portion 23 and the movable plate 2. The second limiting abutting surface 231 is adapted to abut against the first limiting abutting surface 121 when the movable plate 2 slides inward relative to the first sliding groove 11 to the extreme position. Specifically, the extending portion 23 extends into the plugging space, and the extending portion 23 abuts against the resisting portion 12. Specifically, the extending portion 23 and the movable plate 2 are integrally formed. The height of the extending portion 23 is less than the height of the movable plate 2. The second limiting abutting surface 231 is equivalent to the stepped end surface between the extending portion 23 and the movable plate 2. The abutting between the first limiting abutting surface 121 and the second limiting abutting surface 231 can perform reliable and effective sliding limiting on the movable plate 2.

An extending portion 23 and a second tooth 24 are symmetrically provided on the two opposite sides of the movable plate 2 along the second direction. The second direction is perpendicular to the first direction. The direction shown by b in the drawings is the second direction. The second direction may be the width direction of the fixed plate 1 and the movable plate 2.

Specifically, during the process of the movable plate 2 sliding relative to the fixed plate 1, the connecting boss 14 simultaneously slides in the second sliding groove 25, further ensuring the reliable and stable sliding of the movable plate 2.
[0050] Specifically, the connecting boss 14 and the fixed plate 1 are integrally formed.
[0051] In this embodiment, the connecting member 3 is provided as a screw, and the connecting hole 112 is correspondingly provided as a threaded hole. The screw passes through the long hole 22 and is threadedly connected to the connecting hole 112. The movable plate 2 can be tightly pressed against the fixed plate 1 through the screw, thereby realizing the fixation between the movable plate 2 and the fixed plate 1.
[0052] This embodiment is not limited thereto. In addition to being provided as a screw, the connecting member 3 can also be provided as a combination of a bolt and a nut, or fixed by means of a fixed pin, a buckle, etc.
[0053] In this embodiment, a plug connector 15 protrudes from the side of the fixed plate 1 facing away from the movable plate 2. Specifically, a plug hole adapted to the plug connector 15 can be opened on the external panel for installing the wiring harness 4 protection device. The fixed plate 1 can be fixedly plugged onto the external panel through the plug hole.
[0054] Specifically, the plug connector 15 is provided as a ring and is located at the outer edge of the through hole 111.
[0055] In this embodiment, a wire tying head 16 protrudes from the fixing plate 1, and a wire threading hole 161 is formed in the wire tying head 16. Specifically, the wire tying head 16 and the fixing plate 1 are integrally formed. The wire tying head 16, the threading hole 111, and the connecting convex head 14 are sequentially arranged at intervals in the first direction. The arrangement of the wire threading hole 161 enables the external cable tie to be threaded through. The cable tie is threaded through the wire threading hole 161 and wound around the wire harness 4, thereby reliably fixing the threaded wire harness 4.
