Description

Technical Field

[0001] The utility model relates to the technical field of wire harness installation, and more specifically to a wire harness component with a reinforcement structure. Background Art

[0002] A wiring harness is a group of wires used to connect multiple electrical components in an electronic system or electronic device. Wiring harnesses are often used to simplify the assembly and repair of complex circuits by bundling multiple wires together into an organized, manageable wiring structure.

[0003] At present, when the wiring harness assembly needs to be installed through a wall hole, a reinforcement structure is generally used to increase the strength of the wiring harness at the wall hole position. At the same time, the diameter of the wiring harness can be increased to increase the contact range with the wall hole. This is generally done through a wire tube structure. Since the wall hole is opened by a drilling rig, there will be a certain gap between the actual wire tube diameter and the size, resulting in an unstable installation position. Therefore, a reinforcement structure with an expansion effect is required to reduce the existence of the insertion gap. In view of this, we propose a wiring harness assembly with a reinforcement structure. Utility Model Content

[0008] The utility model can wrap the wiring harness inside by strengthening the structure of the pipe fitting through design, thereby increasing the protection of the outer skin of the wiring harness; the expansion piece is combined with the fixed pipe fitting by a threaded connection to achieve the effect of a movable connection, so that the position between the extrusion sleeve and the expansion piece can be conveniently adjusted during rotation, so that the position of the strip groove of the support pipe can be squeezed by the extrusion block to make it open, thereby expanding the diameter of the support pipe and facilitating adjustment to a width corresponding to the size of the wall hole, thus improving the stability of the position fixation and solving the problem of gaps during insertion.

[0023] like Figures 1 to 5 As shown, the utility model relates to a wiring harness assembly with a reinforced structure, including a reinforcing tube 1 sleeved on the outside of the wiring harness. The sleeve of the reinforcing tube 1 can improve the strength of this section of the wiring harness and increase the wear resistance. An expansion piece 2 is movably installed on the outside of the reinforcing tube 1.

[0024] The reinforced pipe fitting 1 includes a fixed pipe 101, an external thread 102 is arranged on the outer wall of the fixed pipe 101, an extrusion sleeve 103 is rotatably installed on the right end portion of the fixed pipe 101, a plurality of extrusion blocks 104 are fixedly arranged on the outer wall of the extrusion sleeve 103, and an adjusting member 3 is movably installed on the right end of the fixed pipe 101; the fixed pipe 101 and the extrusion sleeve 103 are rotatably connected so that the rotation of the fixed pipe 101 will not drive the extrusion sleeve 103 to rotate synchronously, and the setting of the adjusting member 3 facilitates the rotation of the fixed pipe 101.

[0025] The expansion member 2 includes an adjusting tube 201 combined with the external thread 102 on the fixed tube 101, a supporting tube 202 is integrally arranged on the right end side wall of the adjusting tube 201, a plurality of strip grooves 203 are opened on the tube wall of the supporting tube 202, and a limiting groove 204 corresponding to the extrusion block 104 is opened on the tube wall of the supporting tube 202 located at the position of the strip groove 203; the adjusting tube 201 connected by threads can conveniently rotate the fixed tube 101 to move it under the cooperation of threads, and the setting of the strip groove 203 splits the supporting tube 202, so that they can flip upwards respectively when the side plates are squeezed, thereby expanding the diameter of the supporting tube 202, and the setting of the limiting groove 204 facilitates limiting the position of the extrusion block 104 on the extrusion sleeve 103, so that it can maintain the effect of lateral movement, thereby achieving the function of extrusion support.

[0026] In an embodiment of the utility model, the adjusting member 3 includes an extension tube 301, a limit block 302 is fixedly provided on the outer tube wall of the extension tube 301, a rotating block 303 that fits with the left tube wall of the fixed tube 101 is fixedly provided on the side end of the extension tube 301, and a plurality of anti-slip grooves are opened on the annular outer edge of the rotating block 303; through cooperation, the adjusting member 3 structure can be formed, which is convenient for driving the fixed tube 101 to rotate.

[0027] In an embodiment of the utility model, a receiving groove 105 combined with the extension tube 301 is opened inwardly on the left tube wall of the fixed tube 101, and a sliding groove 106 corresponding to the limit block 302 is opened on the groove surface of the receiving groove 105. The cooperation of the receiving groove 105 and the sliding groove 106 can limit the moving distance of the extension tube 301. At the same time, the combination of the limit block 302 and the sliding groove 106 can drive the fixed tube 101 to rotate synchronously when the extension tube 301 rotates.

[0028] In an embodiment of the utility model, a plurality of protrusions 205 are fixedly provided on the outer tube wall of the support tube 202. The shape of the protrusions 205 is cylindrical, and the upper end diameter of the protrusions 205 is smaller than the bottom diameter. The provision of a plurality of protrusions 205 can increase the contact surface between the expansion member 2 and the inner wall of the wall hole, thereby increasing the friction force. In this way, when the fixed tube 101 is rotated, the probability of driving the expansion member 2 to rotate synchronously can be reduced, thereby achieving the effect of adjusting the position of the extrusion sleeve 103.

[0029] In an embodiment of the utility model, the extrusion block 104 is in a semi-arc shape, and the arc surface of the extrusion block 104 is flush with the strip groove 203; the semi-arc shape can be set to open the position of the extrusion strip groove 203 during movement, so that the separated side panels on the support tube 202 can be propped up.

[0030] In an embodiment of the present invention, the shape of the limit block 302 is a regular quadrilateral, and the shape of the slot of the slide groove 106 is the same as the shape of the limit block 302; the regular quadrilateral structure has a good connection and limiting effect, so that the problem of offset is not likely to occur when the extension tube 301 is rotated.

[0031] Working principle: This embodiment provides a wiring harness assembly with a reinforced structure. When in use, the reinforcing pipe 1 is first connected to the expansion piece 2 by threads, and then the wiring harness is passed through the reinforcing pipe 1. When it needs to pass through the wall hole, the expansion piece 2 is placed inside the wall hole. When there is a gap between the expansion piece 2 and the wall hole, the reinforcing pipe 1 can be rotated by rotating it, and then the extrusion sleeve 103 at the side end can be controlled to move horizontally under the threaded cooperation. During rotation, the protrusion 205 structure set on the outer wall of the support tube 202 can increase the friction between the wall hole and the support tube 202, thereby reducing the probability of the fixed tube 101 driving the adjustment tube 201 to rotate synchronously. , so that the extrusion block 104 on the extrusion sleeve 103 can squeeze the position of the strip groove 203 on the support tube 202 to open, so that the wall of the divided support tube 202 can be propped up, thereby expanding the overall diameter of the expansion piece 2 so that it can be squeezed to the inner wall of the wall hole, thereby solving the gap problem and improving the stability of the position of the reinforcement pipe 1 inside the wall hole. When the length of the reinforcement pipe 1 does not match the length of the wall hole, the extension pipe 301 on the adjustment piece 3 can be drawn out from the receiving groove 105 in the reinforcement pipe 1, so as to adjust the length of the reinforcement pipe 1, facilitate the rotation operation, and improve the effect of structural matching.

A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
