Description

Integrated cable extension frame with waterproof structure

The present invention relates to a wire waterproof structure, in particular to a waterproof structure of an integrated wire extending frame.

There are many modern devices, such as meters and lamps, whose internal electronic components must be connected to the outside world with wires, such as but not limited to wires, signal wires, network cables, etc. These wires must pass through the device to connect to the electronic components. A protected frame can penetrate the inside and outside. However, these devices are often in the open air, and it is difficult to prevent external moisture from seeping through the holes and gaps during the wire penetration process. For example, car lights, there are usually many electronic parts inside the car lights. It must have a careful and dense waterproof structure, so how to achieve both wire penetration and tightness and waterproofing has always been an issue that the industry attaches great importance to.

The applicant in this case had applied for a waterproof structure for wire penetration frames on May 30, 2014, and the invention patent was approved and announced as No. I571190. The case includes: a frame base, including at least one frame wall, and the frame wall Provided with a perforation; plural wires: the outer edge of the plurality of wires is integrally formed with a projection package to form a line convex portion. The line convex portion includes a convex portion body accommodated in the perforation, and the convex portion body is facing the inside of the frame wall. One end is provided with a shoulder, and the outer diameter of the shoulder is larger than the outer diameter of the convex body; wherein the convex body is provided with a hook with an outer diameter slightly larger than the outer diameter of the convex body at the end opposite to the shoulder. , so that the locking component is elastically forced into the gap between the convex part body and the perforated hole wall by the material of the locking component or the hook edge; a locking component: the locking component is partially operatively fixed to the convex part The gap between the main body and the wall of the perforated hole can be fixed to the frame wall and can be pressed against the shoulder to form resistance and restriction for pulling the plurality of wires axially outward. Although this case uses the outer edge of the plurality of wires to integrally form a wire-gathering convex part, the plurality of wires and the wire-gathering convex part are not easy to loosen, and the tedious work of threading is avoided, especially in the case of more wires. , the effect is more easily highlighted. And one end toward the inside of the frame wall is provided with a shoulder that can be relatively resisted by the locking member to form a limiting backlash. Pulling, and because the outer edges of the plurality of wires are integrally formed into a linear convex part by the injection package, the axial displacement of the wires is also restricted at the same time. In addition, because the locking component in this case is partially operatively fixed in the gap between the convex body and the perforated hole wall, the locking component can be more secretive and hidden, without exposing too much volume and reducing the appearance. It's cumbersome and uneven. Furthermore, this case can allow relatively large holes to be filled and then be plugged. Therefore, the present invention can provide a connector at one end of the wire that is not too large in size and can be passed through first during the perforation, thereby reducing the cumbersome construction work of riveting the joint after threading.

However, based on continuous research and development, the applicant in this case is still striving to find a better solution. Among them, it is believed that the lock component and the wire collecting convex parts are scattered, and there are improvements in the assembly or integration effects.

In view of the problems of the prior art, the inventor believes that there should be an improved structure. To this end, a waterproof structure of an integrated wire penetration frame is designed, which includes a frame base and at least: a frame wall, and the frame wall is provided with a through hole. ; And a plug, the plug includes a cylinder, one end of the cylinder forms a flange, the flange is against the frame wall, and the cylinder has a plurality of wire holes extending through the cylinder on one end surface , and one section of the column is a soft and tough different material section formed by multi-component injection molding. The outside of the soft and tough different material section includes a plurality of spaced apart convex ring ribs.

The present invention utilizes the soft and tough foreign material section and other parts of the foreign material injection package to be integrated into one body, and the integrated materials are integrated into one body. It is easy to disassemble and assemble, and the transportation and storage of the material are more convenient and economical. And the soft and tough heterogeneous material section includes a plurality of spaced apart convex ring ribs that can be used to fill the gap between the column and the perforated hole wall in the frame wall to achieve a multi-layer waterproofing effect.

And although the soft and tough different material section is a soft and tough material, its two ends are still relatively hard and other parts of the column are relatively hard. Therefore, it can be ensured that the soft and tough different material section still has some relatively hard properties in the soft material. Moreover, the two ends of the soft and tough heterogeneous material section still form a linear connection with the relatively hard column, and there will be no redundant increase in thickness due to nesting and stacking.

In addition, in a preferred embodiment of the present invention, the hole wall of the wire channel is integrally extended by the same material as the soft and tough different material section. Because the soft and tough different material section is made of soft and tough material, it has a better grip on various wires, preventing the wires from stretching and running around, and has a relatively stable effect.

In addition, in the present invention, the inner surface of the hole wall of the wire channel can be formed into a wavy friction surface. The wavy friction surface further enhances the grip of various wires.
