Description

Waterproof plug for wire

Technical Field

The utility model relates to a waterproof plug structure, in particular to a waterproof plug of a wire rod.

Background

Existing wire flashing plugs are typically configured with different bore sizes to accommodate wires of different thicknesses. The structure of the waterproof plug can refer to fig. 1 and 2, and a plug body 1a of the waterproof plug is provided with a through hole 2a with a specific aperture, and the through hole is used for corresponding to a wire L with a specific thickness. Therefore, the user needs to purchase and store different waterproof plugs for different wires. It is very difficult to insert the wire rod thicker than the hole diameter into the waterproof plug, on one hand, the end part of the wire rod can be adversely affected in the inserting process, on the other hand, the waterproof plug can generate larger stress after being inserted, and the risk of the waterproof plug self cracking can be increased after long-time use.

SUMMERY OF THE UTILITY MODEL

The main object of the present invention is to provide a waterproof plug that can be used for wires of different thicknesses.

In order to achieve the above object, the present invention provides a waterproof plug for a wire, comprising a plug body provided with a through hole for passing the wire therethrough, the through hole having a larger inlet section, a smaller outlet section, and a tapered section for transition from the inlet section to the outlet section; the plug body is made of an elastic material which allows the through hole to be enlarged, and a plurality of stress release holes are distributed on the surface of the plug body.

In some embodiments of the present invention, the plug body is provided with the stress release holes in an axially and circumferentially distributed manner along the through hole.

In some embodiments of the present invention, the stress release holes are blind holes, and the depth of the blind holes is distributed in a stepped manner along the axial direction with the conical section.

The waterproof plug can be suitable for wires with different thicknesses, and is favorable for releasing stress generated in the using process, so that the waterproof plug has the advantage of durability.

Detailed Description

In view of the fact that the waterproof plug of the prior art cannot adapt to wires with different thicknesses, and the plug body 1a is easy to crack due to stress after the wires with thicker holes are inserted. The utility model provides a waterproof plug for different wires, and referring to fig. 3, the structure of the waterproof plug comprises a plug body 1b, a through hole 2b for the wires to pass through is arranged on the plug body 1b, and the through hole 2b is provided with a larger inlet section 201b, a smaller outlet section 202b and a conical section 203b for transferring the inlet section 201b to the outlet section 202 b; the plug body 1b is made of an elastic material which allows the through hole 2b to expand, and stress release holes 3 for releasing stress are distributed on the surface of the plug body 1b. The waterproof plug can adapt to wires with different thicknesses to a certain extent. When the wire rod is in sealing fit with the aperture of the outlet section at the minimum, the wire rod can directly pass through the conical section 203b from the inlet section 201b and then pass out from the outlet section 202b, and the waterproof plug is in sealing sleeve connection with the wire rod. When the aperture of the outlet section 202b that the wire rod is thicker than, the inlet section 201b of the waterproof plug can allow the wire rod with different thicknesses to be inserted in the aperture and the elastic deformation range, then the wire rod is continuously inserted into the conical section 203b of the through hole 2b, the conical section 203b is elastically stretched towards the outside due to the thrust of the wire rod, the plug body 1b is easy to generate elastic deformation through the stress release hole 3 in the stretching process, the stress generated by the elastic deformation is reduced, and the fracture of the plug body 1b is avoided. One of the materials used to make waterproof plugs is rubber.

The above description of the inducer and exducer sections as "larger" and "smaller" is used to compare the pore size of the inducer 201b and exducer section 202b, i.e., the pore size of the inducer 201b is larger than the pore size of the exducer section 202b.

With continued reference to fig. 3, the plug body 1b is provided with the stress release holes 3 equally distributed in the axial and circumferential directions of the through-hole 2b. This arrangement can better help the plug body 1b to elastically deform at various positions. The stress release holes 3 may be distributed in other ways, for example, when only local deformation is needed, the stress release holes 3 may be arranged at the position, so as to induce the deformation of the plug body 1b at the position where the stress release holes are arranged.

The stress release holes 3 are blind holes, and the depths of the blind holes are distributed along the axial direction in a stepped mode with the conical sections 203b. The four stress release holes 3 on both sides of the tapered section 203b shown in fig. 3 are correspondingly deeper as the aperture of the tapered section decreases, and in other embodiments, when the length of the tapered section is longer and more stress release holes are located on both sides of the tapered section, the depth of the stress release holes is generally stepped. Such blind holes can satisfy the stress release demand in different thickness positions.

In the in-service use in-process, when needing to wear to establish and install a certain wire rod and carry out water repellent, only need with passing waterproof stopper of wire rod, with waterproof stopper again on the hole (be used for the trompil of crossing the line on the building materials) of wire rod wear to establish the position, just can realize waterproof, the water proof of wire rod.

The embodiments of the present invention are merely illustrative, and not restrictive, of the scope of the claims, and other substantially equivalent alternatives may occur to those skilled in the art and are within the scope of the present invention.
