[0029] Please refer to Figures 1 to 4 , and now a fixing device for a wiring harness connector provided by the present utility model will be described. A fixing device for a wiring harness connector includes a fixed housing 100. A connection and fixing assembly for connecting to the vehicle body is provided on one side of the fixed housing 100. At least one protection slot 110 is opened on the other side of the fixed housing 100. The protection slot 110 is inserted and fitted with the wiring harness connector 300 and surrounds the outer periphery of the wiring harness connector 300. The protection slot 110 is provided with a clamping structure and a limiting structure. The clamping structure is clamped with the wiring harness connector 300 to prevent it from disengaging from the protection slot 110, and the limiting structure is used to limit the lateral displacement of the wiring harness connector 300 in the protection slot 110.

[0030] A fixing device for a wire harness connector provided by the present utility model, compared with the prior art, the fixing housing 100 is connected to the vehicle body through a connection and fixing component on one side, and at least one protection slot 110 is provided on the other side of the fixing housing 100. The wire harness connector 300 is inserted into the protection slot 110, and the protection slot 110 surrounds the outer periphery of the wire harness connector 300. At the same time, the clamping structure of the protection slot 110 forms a clamping connection with the corresponding structure of the wire harness connector 300, which can prevent the wire harness connector 300 from being disengaged from the protection slot 110 in the opposite direction of the insertion direction; the limiting structure of the protection slot 110 forms a limit with the corresponding structure of the wire harness connector 300, which can limit the lateral displacement of the wire harness connector 300 in the protection slot 110. When using the fixing device for a wire harness connector provided by the present utility model, after the wire harness connector 300 is inserted into the protection slot 110, the stability of the wire harness connector 300 can be ensured, and the problems of accidental detachment or short circuit due to shaking can be reduced.

[0031] In some embodiments, please refer to Figure 2 , the clamping structure includes a plurality of clamping grooves 111 provided on opposite sides of the protection slot 110, and the plurality of clamping grooves 111 on the same side are arranged in sequence along the insertion direction of the wire harness connector 300.

[0032] Specifically, through holes are respectively provided at the top and bottom of the protection slot 110, and a plurality of clamping grooves 111 are provided on the same side of the two through holes. The clamping grooves 111 are tapered grooves, and the width of the tapered grooves gradually decreases from near the through holes to away from the through holes. Correspondingly, a plurality of tapered blocks are respectively provided at the top and bottom of the wire harness connector 300. As the wire harness connector 300 is inserted into the protection slot 110, the plurality of tapered blocks are respectively inserted into the plurality of tapered grooves, so as to form a limit in the insertion direction of the wire harness connector 300 and ensure the stability of the wire harness connector 300 in the protection slot 110.

[0033] In some embodiments, please refer to Figure 2 , the clamping structure includes a clamping block 112 provided on the port side of the protection slot 110, and the clamping block 112 extends towards the inside of the protection slot 110.

[0034] Specifically, the clamping block 112 is integrally formed at the top, bottom or lateral port side of the protection slot 110. The clamping block 112 is a wedge-shaped block structure that extends towards the inside of the protection slot 110 and has a certain resilience. Correspondingly, the top, bottom or side of the wire harness connector 300 is provided with a clamping groove 111. As the wire harness connector 300 is inserted into the protection slot 110, the wedge-shaped block first deforms outward under the extrusion of the wire harness connector 300 until it reaches the position of the clamping groove 111. Then, the clamping block 112 rebounds and is stuck in the clamping groove 111, thereby forming a limit in the insertion direction of the wire harness connector 300 and ensuring the stability of the wire harness connector 300 in the protection slot 110.

[0035] In some embodiments, please refer to Figure 2 , the limiting structure includes a limiting groove 113 or a limiting rib 114 provided on the inner side wall of the protection slot 110, and the limiting groove 113 or the limiting rib 114 extends along the insertion direction of the wire harness connector 300.

[0036] Specifically, a limiting groove 113 or a limiting rib 114 is formed on the inner side wall of the protection slot 110, and a limiting protrusion or a limiting recess is formed at the corresponding position of the wire harness connector 300. The limiting protrusion is inserted into the limiting groove 113 as the wire harness connector 300 is inserted, or the limiting recess is sleeved outside the limiting rib 114 as the wire harness connector 300 is inserted. When the protection slot 110 and the wire harness connector 300 are circular structures, the limiting groove 113 or the limiting rib 114 can limit the rotation of the wire harness connector 300 in the protection slot 110. When the protection slot 110 and the wire harness connector 300 are non-circular structures, the limiting groove 113 or the limiting rib 114 can limit the lateral movement of the wire harness connector 300 in the protection slot 110, thereby improving the stability of the wire harness connector 300 in the protection slot 110.

[0037] Wherein, a single protection slot 110 can be opened on the other side of the fixed housing 100 to achieve the insertion fit with a wire harness connector 300. At this time, the clamping structure and the limiting structure provided in the above embodiments can be selectively applied to the protection slot 110. Multiple protection slots 110 can also be arranged side by side on the other side of the fixed housing 100 to achieve the insertion fit with multiple wire harness connectors 300. At this time, the clamping structure and the limiting structure provided in the above embodiments can be selectively applied to multiple protection slots 110. The clamping structure and the limiting structure can be reused or used differently in multiple protection slots 110, which will not be elaborated here.

[0038] Please refer to Figure 1 and Figure 3, the connection and fixation component includes a connection bracket 200, a fixation structure, and an anti-rotation structure. The connection bracket 200 is connected to one side of the fixed housing 100. The fixation structure and the anti-rotation structure are respectively arranged at both ends of the connection bracket 200 on the side away from the fixed housing 100. The fixation structure is connected to the vehicle body to connect the connection bracket 200 to the vehicle body, and the anti-rotation structure is connected to the vehicle body to limit the rotation of the connection bracket 200 relative to the fixation structure.

[0039] Specifically, the fixation structure includes a fixing sleeve 211 and a first connecting member 213. Among them, a first sinking groove 210 is provided at one end of the connection bracket 200 on the side away from the fixed housing 100. The fixing sleeve 211 is integrally formed in the middle of the bottom surface of the first sinking groove 210. A plurality of first reinforcing ribs 212 are radially arranged on the bottom surface of the first sinking groove 210, which can improve the structural strength of the first sinking groove 210 and the fixing sleeve 211. The fixing sleeve 211 has an oblong hole 2141 inside. The first connecting member 213 includes a bolt and a nut. The bolt is welded to the vehicle body. The bolt passes through the oblong hole 2141 and is connected to the vehicle body. The nut is screwed onto the bolt to fix the connection bracket 200 to the vehicle body. The bolt can move along the length direction of the oblong hole 2141 to adjust the position of the connection bracket 200 relative to the vehicle body. After the connection bracket 200 is adjusted to a suitable position, the nut is tightened.

[0040] Preferably, a metal bushing 214 is embedded in the oblong hole 2141. The metal bushing 214 is conformally arranged with the oblong hole 2141. At this time, the bolt of the first connecting member 213 passes through the inner hole of the metal bushing 214 and is connected to the vehicle body. The metal bushing 214 can improve the structural strength of the oblong hole 2141 itself, reduce the deformation tendency of the oblong hole 2141 and at the same time can reduce the wear of the edge of the oblong hole 2141.

[0041] Specifically, the anti-rotation structure includes an anti-rotation sleeve 221 and a second connecting member 223. Among them, a second sinking groove 220 is provided at the other end of the connection bracket 200 on the side away from the fixed housing 100. The anti-rotation sleeve 221 is integrally formed in the middle of the bottom surface of the second sinking groove 220. A plurality of second reinforcing ribs 222 are radially arranged on the bottom surface of the second sinking groove 220, which can improve the structural strength of the second sinking groove 220 and the anti-rotation sleeve 221. A plurality of convex ribs 2211 are circumferentially arranged on the inner hole of the anti-rotation sleeve 221. The second connecting member 223 also includes a bolt and a nut. The bolt of the second connecting member 223 passes through the anti-rotation sleeve 221 and is connected to the vehicle body. The plurality of convex ribs 2211 abut against the outer periphery of the second connecting member 223 to form the effect of frictional damping, avoiding the rotation of the connection bracket 200.

[0042] Preferably, a plurality of elastic pieces 2212 are circumferentially arranged on the inner hole of the anti-rotation sleeve 221, and the plurality of elastic pieces 2212 are respectively arranged in the gaps between adjacent two convex ribs 2211. The lower end of the elastic piece 2212 is integrally formed with the inner wall of the anti-rotation sleeve 221. The upper end of the elastic piece 2212 is inclined and extends towards the axis direction of the anti-rotation sleeve 221. The upper end of the elastic piece 2212 extends to the inner side of the convex rib 2211 in the non-force state. The end of the elastic piece 2212 refers to the upper end of the elastic piece 2212. When the bolt of the second connecting piece 223 is inserted between the plurality of convex ribs 2211, the bolt extrudes the end of the elastic piece 2212 outwards, so that the end of the elastic piece 2212 forms an elastic force towards the axis direction of the anti-rotation sleeve 221, that is, the end of the elastic piece 2212 presses against the outer periphery of the second connecting piece 223, which can further form a circumferential frictional damping for the bolt of the second connecting piece 223 and avoid the rotation of the connecting bracket 200.

[0043] Based on the same inventive concept, the present invention also provides a vehicle, which uses the above-mentioned wire harness connector fixing device, so it has the same beneficial effects as the above-mentioned wire harness connector fixing device, and will not be described in detail here.

[0044] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
