Waterproof structure of wire piercing frame seat

The invention relates to a waterproof structure, in particular to a waterproof structure of a wire piercing frame.

There are many frames in which a wire material must be connected to the outside, such as a meter case and a lamp holder frame, and the wire may be a wire, a signal wire, a mesh route, etc., and the wire must penetrate the frame. The perforation of the frame wall can penetrate the inside and the outside, but in the process of penetration, the moisture of the outside world may be infiltrated by the perforation, and thus has been a subject that various operators have always attached importance to.

The foregoing, for example, but not limited to, the lamp is a lighting fixture for a vehicle. Since the interior of the lamp often has many electronic components, it must have a proper waterproof structure.

Please refer to the diagram in Figure 7. Since the lights must have power, signal and other multiple wires (52) to provide power or signal transmission, there must be perforations in the frame wall (5) of the frame (not shown). 51) to allow the aforementioned plurality of wires (52) to pass through.

Since there is a gap between the perforation (51) and the repetitive wire (52) to form a water seepage into the interior of the lamp, a designer will let the plurality of wires (52) be first placed in a kit (54). And then the kit (54) is placed in the perforation (51). However, the problems with this prior art are:

1. Since the kit (54) allows the plurality of wires (52) to be axially stretched, since it is easy to be stretched, it is naturally easy to pull back, so that the wires are easily displaced in the axial direction under easy pulling. And because the plurality of wires (52) extend axially through the kit (54), the operation becomes more cumbersome as the number of the plurality of wires (52) increases.

2. Although there is also a design (53) on the frame wall (5) to limit the design of the kit (54) to pull back, it can only limit the pullback of the kit (54), and it is still difficult to avoid the plurality of wires (52). Axial displacement.

3. The stopper (53) is also fixed to the frame wall (5) because it is disposed at the outer end of the sleeve (54), and is wider than the outer diameter of the overall sleeve (54), so that the appearance Untidy and complicated to present unevenness.

4. In addition, since usually one end of the plurality of wires (52) is often provided with a joint (not shown), since the prior art avoids the inner diameter of the perforation (51), the hole wall and the kit (54) are too The large water seepage space, so the perforation (51) can not be made too large, but because of this, the volume of the joint is usually in a large state, usually after the plurality of wires (52) pass through the perforation. Riveting joints, construction work is cumbersome.

In view of the problems of the prior art, the inventors believe that there should be an improved structure. For this purpose, a waterproof structure for a wire piercing frame is provided, comprising a frame, the frame having at least one frame wall: the frame wall is provided with a perforation And a plurality of wires: the outer edge of the plurality of wires integrally form a collecting line protrusion by the projecting package, the line protruding portion includes a convex body received in the through hole, and the convex body is facing toward the inside of the frame wall One end is provided with a shoulder, the outer diameter of the shoulder is larger than the outer diameter of the convex body; and a locking member is locally operatively fixed to the gap between the convex body and the perforated hole wall, and It can be fixed to the frame wall and can be abutted against the shoulder to form a resistance and limit for pulling the plurality of wires axially outward.

The effect of the invention is:

1. Since the outer edge of the plurality of wires is integrally formed by the projecting package, a set of line convex portions is formed. The number of wires and the convex portion of the wire are not easily loosened, and the work of avoiding the stretching is cumbersome, especially in the case of more wires, the effect is more easily highlighted.

2. The present invention is provided with a shoulder facing one end of the frame wall to be relatively resisted by the locking member to form a restricted pullback, and since the outer edge of the plurality of wires integrally forms a line protrusion by the package, the wire is also At the same time, the axial displacement is limited.

3. Since the locking member of the present invention is partially operatively fixed to the gap between the convex body and the wall of the perforating hole, the locking member can be relatively hidden and built in, so that more volume is not exposed, and the volume is reduced. The appearance is cumbersome and uneven.

4. Since the present invention can tolerate relatively large perforations and then fill them, the present invention can provide that the volume of the joint at one end of the wire is not excessively large, and is passed before the perforation, and the construction work of riveting the joint after the threading is reduced is cumbersome. .
