It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be implemented in sequences other than those illustrated or otherwise described herein. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the accompanying claims.

With rapid development of the automobile industry and continuous improvement and promotion of living conditions of people, automobiles have become one of the indispensable transportation means for people to travel. In recent years, automobiles are required to be light and low in fuel consumption. To the extent that the vehicle body structure is implemented on an automobile design product, the attempts of aluminum alloy and carbon fiber lightweight materials and the like are gradually started from a conventional steel vehicle body.

The front wall plate of the whole automobile is classified from the material angle of parts and mainly comprises a steel plate, an aluminum plate and a carbon fiber plate. The front wall plate of the automobile mainly plays a role in separating the front cabin from the member cabin, and meanwhile, carriers for fixing parts such as a plurality of wire harnesses and the like are needed to be provided on the front wall plate, and the external thread structure is mainly used. The current mainstream front wall plate provides external thread connection mode and mainly comprises steel body welding steel bolts, aluminum body welding aluminum bolts and carbon fiber body bonding bolts, and simultaneously three types of bolts can be considered to be rivet after the automobile body is perforated. However, the common disadvantage of the above methods is that the external screw connection structure is integrated with the vehicle body after welding (bonding) or riveting, and the external screw connection structure cannot be disassembled and is difficult to maintain and replace.

To solve the above-mentioned problems, as shown in fig. 1-5, the present application provides a connector 1, where the connector 1 is used for connecting a metal plate 3 of a vehicle body, and the metal plate 3 of the vehicle body is provided with a preformed hole 301.

The support frame 20 deforms in a direction away from the connecting portion 11 with the abutting portion 201 abutting against the connecting rod 2 so that the stopper portion 202 abuts against the back surface of the vehicle body sheet metal 3.

Thus, when the connecting rod 2 is connected to the connecting hole 111, the connector 1 is limited by the stopper portion 12 and the limiting portion 202, so that the connector 1 can be connected to the vehicle body sheet metal 3 by abutting the connecting rod 2. Under the condition that the connecting rod 2 is separated from the connecting hole 111, the limiting part 202 is separated from the metal plate 3 of the vehicle body, so that the connecting piece 1 can be separated from the metal plate 3 of the vehicle body, and the maintenance and the replacement are convenient.

Therefore, the utility model can solve the problems that the connecting piece 1 and the metal plate 3 of the automobile body in the prior art are fixed together, cannot be disassembled and are difficult to repair and replace.
