Description

[Detailed description of the invention] This invention relates to the structure of a vehicle headlamp, especially the conductive part, and its purpose is to strengthen vibration resistance and simplify the work process. It is in.

Looking at the structure of the conductive part of conventional vehicle headlights, as shown in Figure 1A as an example as a cross-sectional view, the light bulb L
For example, connect the conductive wires L to the plurality of lead wires P' coming out of the sealing part P of a halogen light bulb, put the wires in this state into the cap E, and pour the adhesive while holding them in place.
Later, terminals T are connected to each of the conductive wires at the bottom of the base to complete the process, and the bottom is shown in the figure.

However, with this configuration, problems such as troublesome connections between lead wires and terminals, misalignment of lead wires that occur when the poured adhesive hardens, and short circuits due to mutual contact occur, as well as complicated construction. Requires a work process.

There are other drawbacks. The present invention is intended to eliminate the problem of slanting as much as possible, and the specific structure of each embodiment will be described in detail below with reference to FIG. 2 and subsequent figures.

FIG. 2 is an enlarged perspective view of the main parts showing the first embodiment of the present invention, in which P' is a lead wire buried in the sealing part P, and G is a cross-sectional view of the lead wire with an opening on the inside so as to hold the sealing part. A grip part is bent into a C shape, M is an elongated rod part integrally formed with a terminal to be described later on one side of the grip part, T is a terminal, and a lead wire is connected to the rod part and the terminal. A conductive portion C is thus completed, including a tongue piece t for stopping P' and a tongue piece t' for stopping a connector (not shown).

The present invention has a diagonal configuration.Next, to describe the operation and effect along with the assembly procedure, the grip part G of the conductive part C is clamped and held on one side of the sealing part P, and at this time, the tongue piece of the rod part M is The lead wire P' comes to t, so spot weld it, caulk it,
etc., and then attach another conductive part C to the other side of the sealing part in the same manner as above, and in this state, as shown in FIG. 3 as a cross-sectional view of the main part, The periphery of the portion M is filled and fixed with a heat-resistant resin such as polycarbonate or epoxy to form the holding portion A, and this holding portion is inserted into the mounting portion R at the rear of the resin lamp body B.

Thereafter, the holding part A and the mounting part R are melted and bonded using ultrasonic waves or high frequency waves, or fixed with an adhesive.

According to the present invention, the conductive part C, which has the terminal T integrally connected to one side of the grip part G, is easily and strongly fixed to the light bulb, so that it can be attached to the mounting part R of the lamp body B. It is extremely easy to install, has a small number of parts, and furthermore, the focus position of the light bulb can be extremely easily positioned before fixing the holding part A, and the simple structure also simplifies the work process. As a result, a good product with excellent vibration resistance can be obtained.

Now, what is shown in FIG. 4 is a different embodiment that has three lead wires P' in the sealing part P and is suitable for a type of light bulb that can project light upward and downward, and is different from the first embodiment. To describe only the different points, the tongue piece t that fixes the left and right lead wires P' is attached to the rod part M.
The terminal T is folded back and bent, and the conductive part connected to the lead wire in the center is formed so that the grip part G' directly clamps the lead wire. In terms of the model, these conductive parts are inserted into a mounting part that has three insertion holes formed on the rear surface of the lamp body (not shown), and are filled with adhesive to form the completed model headlamp. It is compatible.

Furthermore, Fig. 5 applies to a type of lamp in which the mounting part R' that connects each conductive part C attached to the light bulb protrudes in front of the lamp body B, as shown in Fig. 5A. Bring the mounting part R' closer to the lamp body, insert each conductive part into each insertion hole of the mounting part as shown in the cross-sectional view at the front of the figure, adjust the focal position of the light bulb, and then connect each conductive part to the Measure the filling hole with adhesive,
A further different embodiment is shown in which a connector K is fitted from the back side.

In this way, the lamp body and the light bulb are firmly positioned and fixed, resulting in an even stronger product with excellent vibration resistance.

The second and third modified embodiments are similar to the first modified embodiment.
In addition to producing the same effects as the embodiment, the present invention has the advantage that the headlight itself can be made even more lightweight.

In the embodiment shown in FIG. 5, if a tongue piece tI/ for preventing detent is provided, the fixed state becomes even stronger and more stable.
