Description

Technical Field

[0001] The utility model relates to the technical field of wire harness fixing brackets, in particular to a compact connector anti-tearing wire harness tension-resistant fixing bracket. Background Art

[0002] The automotive wiring harness is the carrier of electrical energy and signal transmission for the entire vehicle. When arranging the wiring harness, it is necessary to fix the wiring harness with a fixed bracket to ensure that there is no dynamic or static interference between the wiring harness and surrounding parts, and to avoid wear of the wiring harness during vehicle driving.

[0003] For example, the utility model: "Wire harness fixing bracket and vehicle", with the announcement number of "CN206664493U", provides a first reinforcing rib on the second branch, which can significantly increase the strength of the bracket body and avoid deformation of the bracket body when the bracket body is installed on the vehicle. However, during the implementation of this patent, the wire harness can only be wired or fixed. When the wire harness is long, the wire harness cannot be reeled in. In addition, during use, if the wire harness is subjected to pulling force, the bracket acts as a buffer, making the wire harness and the bracket joint easily torn off. Therefore, the utility model provides a compact joint anti-tear wire harness tensile fixing bracket to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a compact anti-tear wire harness tension fixing bracket for connectors, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a compact connector anti-tear harness tensile fixing bracket, comprising a winding sleeve, a bracket mounting top plate, a buffer sleeve and a mounting rod, a buffer sleeve being installed at one end of the bottom of the bracket mounting top plate, and a buffer pull rod being installed inside the buffer sleeve, a winding sleeve being installed at the bottom of the buffer pull rod, and through grooves being provided at both ends of the winding sleeve, a second clamping ring being installed on the outside of the winding sleeve, and a first clamping ring being provided on the outside of the winding sleeve, a first wire plate being installed at one end of the bottom of the bracket mounting top plate away from the buffer sleeve, and a first wire hole being provided inside the first wire plate.

[0006] Preferably, a buffer spring is installed on the top of the buffer pull rod, and one end of the buffer spring away from the buffer pull rod is connected to the buffer sleeve.

[0007] Preferably, connecting rods are installed at both ends of the mounting rod, the connecting rods pass through the through slots, and the ends of the connecting rods away from the mounting rods are connected to the first clamping ring.

[0008] Preferably, a fixing spring is installed at the bottom of the mounting rod, and one end of the fixing spring away from the mounting rod is connected to the winding sleeve.

[0009] Preferably, a second wire plate is installed at the bottom of the winding sleeve away from one end of the first wire plate, and a second wire hole is provided inside the second wire plate.

[0010] Preferably, mounting screw holes are provided at both ends of the top of the bracket mounting top plate.

[0011] Preferably, an anti-rust layer is provided on the outer side of the first wire plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The compact connector anti-tear harness tensile fixing bracket is equipped with a winding sleeve. When in use, the wiring harness can be passed through the first wire hole and the second wire hole, and the excess wiring harness can be wound around the outside of the winding sleeve to prevent the wiring harness from being scattered and entangled with each other, which can achieve the effect of wiring management.

[0014] 2. This compact connector anti-tear harness tensile fixing bracket is equipped with a first clamping ring, a fixing spring, a second clamping ring, a mounting rod, and a connecting rod. After the wiring harness is wound around the outside of the winding sleeve, the elastic action of the fixing spring causes it to push the mounting rod to move. The mounting rod drives the first clamping ring to move together through the connecting rod. The wiring harness can be clamped by the first and second clamping rings to prevent the wiring harness from falling off the winding sleeve.

[0015] 3. The compact connector anti-tear wire harness tensile fixing bracket is installed with a buffer rod, a buffer spring and a buffer sleeve. During use, if the wire harness is subjected to pulling force, the winding sleeve can be forced to move upward or downward, so that the buffer rod stretches or compresses the buffer spring. The buffer spring can have a buffering effect, reducing the influence of the pulling force on the wire harness and the bracket mounting top plate, thereby avoiding the wire harness and the bracket mounting top plate from being broken due to force, and when the wire harness is no longer subjected to pulling force, the elastic action of the buffer spring can pull or push the winding sleeve to move and reset through the buffer rod.

A buffer spring 11 is installed at the top of the buffer pull rod 6, and the end of the buffer spring 11 away from the buffer pull rod 6 is connected to the buffer sleeve 12. If the wiring harness is subjected to pulling force, the winding sleeve 1 can be forced upward The buffer rod 6 stretches or compresses the buffer spring 11, and the buffer spring 11 can achieve a buffering effect. A second clamping ring 13 is installed on the outside of the winding sleeve 1, and a first clamping ring 2 is sleeved on the outside of the winding sleeve 1. A first wire plate 4 is installed on the end of the bottom of the bracket mounting top plate 7 away from the buffer sleeve 12, and a first wire hole 5 is provided inside the first wire plate 4. An anti-rust layer is provided on the outside of the first wire plate 4, which is beneficial to extending the service life of the first wire plate 4.

A fixing spring 8 is installed at the bottom of the mounting rod 14, and the end of the fixing spring 8 away from the mounting rod 14 is connected to the winding sleeve 1. The elastic action of the fixing spring 8 pushes the mounting rod 14 to move, and the mounting rod 14 drives the first clamping ring 2 to move together through the connecting rod 15, so that the wiring harness can be clamped by the first clamping ring 2 and the second clamping ring 13 to prevent the wiring harness from falling off the winding sleeve 1.

[0023] A second wire plate 9 is installed at the bottom of the winding sleeve 1 away from the first wire plate 4, and a second wire hole 10 is provided inside the second wire plate 9, through which the wire harness can be wired.

[0024] Working principle:

[0025] When in use, the bracket mounting top plate 7 can be fixedly installed at the designated position, and then the wiring harness can be passed through the second wire hole 10 first, and then the excess wiring harness can be wound around the outside of the winding sleeve 1, and then the wiring harness can be passed through the first wire hole 5;

[0026] At this time, the elastic action of the fixing spring 8 causes it to push the mounting rod 14 to move, and the mounting rod 14 drives the first clamping ring 2 to move together through the connecting rod 15, so that the wiring harness can be clamped by the first clamping ring 2 and the second clamping ring 13 to prevent the wiring harness from falling off the winding sleeve 1;

[0027] During use, if the wiring harness is subjected to a pulling force, the winding sleeve 1 can be forced to move upward or downward, so that the buffer pull rod 6 stretches or compresses the buffer spring 11. The buffer spring 11 can play a buffering effect, reducing the influence of the pulling force on the wiring harness and the bracket mounting top plate 7, thereby preventing the wiring harness and the bracket mounting top plate 7 from being broken due to the force;

[0028] When the wiring harness is no longer subjected to pulling force, the elastic action of the buffer spring 11 can pull or push the winding sleeve 1 through the buffer pull rod 6 to move and reset.
