Problems solved by technology
[0002] Vehicle headlights generally have a lamp housing, a reflective bowl, a lamp holder, a lampshade and other components. In the lampshade, the bulb is clamped on the lamp holder, an insulating sheet and a wire harness are arranged in the lamp holder, and a contact is provided at the end of the wire harness, and the contact contacts and the lamp cap of the bulb are in conflict to form an electrical connection; in the existing vehicle headlight wire harness components The insulating sheet fits loosely with the small contacts, and the position of the small contacts cannot be fixed. During the production and assembly process, it is easy to cause improper assembly, resulting in poor contact of the bulb and affecting work efficiency.

The invention relates to a contact fixing device of a headlamp, which is provided with a lamp holder, an insulator and a wire harness, wherein the insulator and the wire harness are arranged in the lamp holder. The ends of the wire harness are fixedly connected with contacts, the insulator is provided with self-lock holes for the wire harness to penetrate through, and the contacts at the ends of the wire harness are fastened into the self-lock holes. The contacts at the ends of the wire harness can be effectively positioned by the self-lock holes arranged on the insulator, so that firm matching among the contacts and the insulator is guaranteed. The self-lock holes of the insulator are big-end-up taper holes with steps and are in the shape matched with the contacts, so that the wire harness can pass through smoothly, and the contacts can be locked reliably. The insulator can slide limitedly upwards and downwards in the lamp holder, and a spring is arranged between the insulator and the bottom of the lamp holder, so that a bulb mounted in the lamp holder is excellent in contact with the contacts, and design is reasonable.
