Description

Technical Field

[0001] The utility model relates to the technical field of wire harness fixing equipment, in particular to a fixing bracket for an automobile wire harness connector. Background Art

[0002] A connector is a coupling device that connects electrical terminals to form a circuit. Generally, there are nearly 100 types of connectors needed for a car, and a single car model uses hundreds of connectors. As people's requirements for car safety, environmental protection, comfort, and intelligence are getting higher and higher, the application of automotive electronic products is increasing, which makes the number of automotive connector applications show an upward trend.

[0003] Existing connectors are generally fixed to the vehicle body using matching plastic fixing clips. One fixing clip can only fix one set of connectors. When multiple sets of connectors need to be fixed between wiring harnesses, this fixing method takes up a large space on the vehicle body, and the strength of the fixing clip is limited. The fixing plug-in is easy to shake and fall off, and the wire connection is unreliable. Summary of the invention

[0004] In order to solve the problem that the existing multiple groups of connectors use fixing buckles that occupy a large space in the vehicle body and the limited strength of the fixing buckles makes the wire connection unreliable, the utility model proposes an automobile wiring harness connector fixing bracket, the anti-error protrusion in the clamping structure in the fixing frame coincides with the groove opened on the wiring harness connector, preventing the automobile wiring harness connector from being misinstalled and shaking, and the limit block in the clamping structure is clamped together with the spring clip and the limit part on the wiring harness connector to ensure the stability of the wiring harness connector after it is assembled in place.

[0005] In order to achieve the above purpose, the technical solution of the utility model is:

[0006] A fixing bracket for a wiring harness connector of an automobile, comprising a bracket body, a plurality of fixing frames for clamping with the wiring harness connector are provided through the bracket body, a clamping structure is provided in the fixing frame, the clamping structure comprises anti-mistake protrusions provided on the upper and lower side walls of the fixing frame and limit blocks provided on the left and right side walls of the fixing frame, the anti-mistake protrusions cooperate with the grooves provided on the wiring harness connector, and both sides of the wiring harness connector are provided with spring cards and limit parts for clamping with the limit blocks to realize the clamping of the wiring harness connector and the fixing frame. The spring cards and limit parts are respectively clamped on both sides of the vertical part and cooperate with the anti-mistake protrusions to ensure the stability of the wiring harness connector plugging.

[0007] Furthermore, the anti-mistake protrusions on the upper and lower side walls of the fixing frame are arranged alternately or correspondingly to adapt to different types of wiring harness connectors.

[0008] Furthermore, both ends of the bracket body are provided with mounting plates, the mounting plates are provided with mounting holes, the bracket body is fixed to the vehicle through the mounting holes, and the bracket body is fixed to the vehicle by bolts passing through the mounting holes.

[0009] Furthermore, the cross-section of the limit block is "U"-shaped, and the limit block includes a vertical part and a horizontal part. After the spring card enters the fixed frame, it is clamped on the side of the vertical part close to the horizontal part, and after the limit part enters the fixed frame, it is clamped on the side of the vertical part away from the horizontal part.

[0010] Furthermore, the edge of the vertical portion away from the horizontal portion is a chamfered structure. The chamfered structure 7 is conducive to the elastic bending of the spring card and reduces the risk of damage to the spring card.

[0011] Furthermore, one end surface of the anti-error protrusion is flush with the end surface of the bracket body, and there is a gap between the other end surface and the end surface of the bracket body.

[0012] Through the above technical scheme, the beneficial effects of the utility model are as follows: the utility model is provided with multiple groups of fixing frames on the bracket body to solve the problem of centralized fixing of multiple groups of connectors. The anti-error protrusions in the fixing frame clamping structure overlap with the grooves on the wiring harness connector, which can effectively prevent the plug-in from shaking and avoid poor contact of the wiring harness connector terminals. The limit blocks in the clamping structure are clamped together with the spring clips and limit parts on the wiring harness connector to ensure the stability of the wiring harness connector after it is assembled in place. At the same time, the fixed bracket occupies little space, and the multiple fixing frames on the bracket body are also conducive to the aesthetics of the wiring harness layout and the optimization of the wiring harness length.
