Description

Technical Field

[0001] The utility model relates to the technical field of wire harness brackets, in particular to an arc-shaped wire harness support bracket for an automobile engine. Background Art

[0002] The engine is an important component in a car. In a car engine, there are many wiring harnesses connected to other components. During the use of the engine, a large amount of heat will inevitably be generated. Therefore, the wiring harness cannot come into contact with the cylinder body of the engine. Otherwise, overheating of the wiring harness may cause a safety accident. Therefore, the wiring harness needs to be fixed and support is provided at the bottom of the wiring harness to isolate the wiring harness from the cylinder body of the engine. The wiring harness support frame in the prior art has the following defects: First, the existing wiring harness support frame is usually fixed to the connecting piece on the cylinder body by two fixing bolts. In actual operation, the staff needs to fix the wiring harness on the wiring harness support frame while aligning the two mounting holes on the wiring harness support frame with the positions of the two mounting holes on the connection, and then complete the installation. This will cause inconvenience to the staff during installation and greatly affect the staff. installation efficiency; second, in order to improve the heat insulation effect, the wire harness needs to be wrapped with a corrugated tube, but the wire harness support frame in the prior art does not have a limiting function for the corrugated tube. After long-term use, the corrugated tube is prone to relative position with the wire harness, which causes the position of the wire harness to be exposed, affecting the protection effect of the wire harness; third, in order to improve the fixing effect of the wire harness, cable ties are usually used to fix the wire harness on the wire harness support frame. However, due to the limited space in the car, the cable ties are directly fixed on the surface of the wire harness and the wire harness support frame, which is not only inconvenient to install, but also has a poor fixing effect; fourth, since the wire harness support frame is subjected to high temperature environment for a long time, the material of the wire harness support frame is usually plastic. Therefore, the wire harness support frame is prone to aging, especially the position where the wire harness support frame is connected to the connector, which is prone to breakage, which can easily lead to safety accidents. Summary of the invention

[0003] In order to solve the above problems, the utility model provides an arc-shaped wire harness support frame for automobile engines, which can ensure the stable position of the wire harness and the corrugated tube on the wire harness, is easy for workers to install, and can extend the service life.

[0005] By adopting the above technical solution, first, the wiring harness connected to the engine is brought in through the wire inlet, and then the branch wires on the wiring harness are respectively output through the first wire outlet and the second wire outlet. The branch wires on the wiring harness will be limited in the first limiting groove on the support frame body, and then the clamping assembly is inserted into the connecting hole on the engine cylinder block. Since the clamping assembly includes a clamping block fixedly connected to the first mounting block, a first elastic clamp connected to the clamping block, and a second elastic clamp connected to the clamping block, when the clamping block is inserted into the first elastic clamp and the second elastic clamp, one end of the support frame body is fixed to the engine cylinder block, so that the fixing work of one end of the support frame body can be quickly completed, and subsequent staff can free up their hands to make the mounting hole on the second mounting block, and then quickly install the support body on the engine cylinder block through the fixing bolts, thus completing the rapid installation of the support frame body.

[0006] A further configuration of the utility model is as follows: the support frame body is provided with a plurality of through holes, the through holes can accommodate the insertion of cable ties, and the through holes penetrate the bottom of the first limiting groove.

[0007] With the above technical solution, since a plurality of through holes are provided on the support frame body, and the through holes can accommodate the insertion of cable ties, the cable tie can be passed through two of the through holes, and then the wiring harness can be fixed between the cable tie and the support frame shell. This can further improve the fixing effect of the cable tie on the wiring harness. At the same time, the cable tie needs to occupy less space, which is beneficial to the layout of the space inside the vehicle.
