Description

Technical Field

[0001] The utility model relates to the technical field of wire equipment, in particular to a household parallel three-wire wire. Background Art

[0002] During the process of household wire wiring, wires usually need to be branched or separated at different positions to meet the connection requirements of household appliances;

[0003] However, existing wire assemblies often lack effective separation and fixing mechanisms. The separation of wires generally requires manual tearing or using tape to wrap the separated wires together, resulting in the wires being prone to scattering during the wiring process, making them difficult to manage and fix, increasing the wiring difficulty and potential safety hazards;

[0004] In addition, traditional wire assemblies may damage the wires when separating them, affecting the service life and safety of the wires;

[0005] Therefore, a household parallel three-wire wire is designed. Summary of the Utility Model

[0006] The main purpose of the utility model is to provide a household parallel three-wire wire. Through the wire assembly and the limit assembly, and designs such as a knob and a conical ring, it is convenient to separate, lock and release the wires.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0012] As a further limitation of the present technical solution, the inner wall of the conical ring is an arc-shaped ring with a large cross-section at one end and a small cross-section at the other end. The auxiliary limiting elastic sheet and the limiting elastic sheet are elastic and can undergo elastic deformation when the conical ring and the connecting ring move.

[0013] As a further limitation of the present technical solution, the cross-section of the end of the limiting elastic sheet connected to the external thread sleeve is larger than that of the other end.

[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0030] A three - wire parallel connection for household use includes a wire assembly 1. The wire assembly 1 includes three wires, the outer walls of the insulating layers of the wires are connected, and the wire assembly 1 passes through a limiting assembly;

[0031] The three wires of the wire assembly 1 respectively include a live wire, a ground wire, and a neutral wire;

[0032] The limiting assembly includes an external - thread sleeve 5, a limiting elastic piece 6, an auxiliary limiting elastic piece 7, a connecting ring 9, a knob 2, and a conical ring 10. The wire assembly 1 passes through the auxiliary limiting elastic piece 7, the limiting elastic piece 6, and the external - thread sleeve 5. One end of the external - thread sleeve 5 fixes one end of a number of circumferentially evenly arranged limiting elastic pieces 6. The inner wall of each other end of the limiting elastic piece 6 is respectively fixedly connected to the outer wall of the auxiliary limiting elastic piece 7. The inner wall of the auxiliary limiting elastic piece 7 fits the outer wall of the wire assembly 1. The inner walls of the auxiliary limiting elastic piece 7 and the limiting elastic piece 6 are arc - shaped inner walls. The external - thread sleeve 5 is threadedly connected to the connecting ring 9. One end outer wall of the connecting ring 9 is fixedly connected to the knob 2, and the other end of the connecting ring 9 is fixedly connected to the conical ring 10;

[0033] The other end of the external thread sleeve 5 is fixedly connected to a support ring 3. At least one auxiliary pull ring 4 is fixedly connected to the inner wall of the support ring 3. The auxiliary pull rings 4 are evenly arranged in a circle. The auxiliary pull ring 4 is crescent-shaped and its two ends are fixed to the inner wall of the support ring 3.

[0034] In this embodiment, there are two auxiliary pull rings 4. The two auxiliary pull rings 4 and the support ring 3 form three wire passing holes for a single wire to pass through. The two auxiliary pull rings 4 are respectively used to assist in separating the three wires.

[0035] When two wires are needed, one wire of the wire assembly 1 is torn off and the remaining two wires are used.

[0036] In this embodiment, rotating the knob 2 can drive the connecting ring 9 and the tapered ring 10 to move. The movement of the connecting ring 9 along the external thread sleeve 5 can realize the tightening and release of the limiting elastic piece 6 and the auxiliary limiting elastic piece 7. When the tapered ring 10 moves towards the direction close to the support ring 3, the tapered ring 10 tightens the limiting elastic piece 6 and the auxiliary limiting elastic piece 7 to realize the fixation of the limiting component. The limiting component is arranged at the connection where the wires of the wire assembly 1 are separated and not separated to realize the locking of the wire assembly 1 and prevent the wires from separating further.

[0037] In this embodiment, after the wire passes through the area between the auxiliary pull ring 4 and the support ring 3 of the limiting component and the limiting component is moved, under the thrust of the auxiliary pull ring 4, the wires can be separated to realize the separation treatment of the wires.

[0038] The inner wall of the tapered ring 10 is an arc-shaped ring with a large cross-section at one end and a small cross-section at the other end. The auxiliary limiting elastic piece 7 and the limiting elastic piece 6 are elastic and can undergo elastic deformation when the tapered ring 10 and the connecting ring 9 move.

[0039] By setting the auxiliary limiting elastic piece 7 and the limiting elastic piece 6, the auxiliary limiting elastic piece 7 can fit the outer wall of the wire to form a cylindrical channel to facilitate the movement of the wire, and the elastic deformation of the elastic limiting piece 6 can drive the auxiliary limiting elastic piece 7 to lock the wire.

[0040] The cross-section of the end of the limiting elastic piece 6 connected to the external thread sleeve 5 is larger than the cross-section of the other end.

[0041] The insulating layer of the wire adopts a tearable structure, and any one wire can be separated alone for wiring without damaging other wires. The adjacent wires of the wire assembly are encapsulated together by pressing or extrusion process, which can ensure that the wires are easy to separate during use and at the same time maintain structural stability.

[0042] The inner core of the wire is a high-conductivity copper core, and the insulating layer adopts a high-temperature resistant and flame-retardant material.

[0043] Each of the wires has an insulating layer of a different color, including yellow, green, and red, to facilitate the distinction of wire functions.

[0044] The auxiliary pull ring 4 is a smooth-surfaced plastic ring.

[0045] During use, manually tear the ends of the wires of the wire assembly 1 and then pass them through the area between the auxiliary pull ring 4 and the support ring 3 of the limit assembly to disperse the wires. Then, pull the limit assembly to the length where the wires need to be separated and lock the limit assembly to lock the wire assembly 1 and prevent the wires from separating further.

[0046] The specific embodiments of the utility model have been described in detail above, but they are only examples, and the utility model is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modification or substitution of the utility model is also within the scope of the utility model. Therefore, all equal transformations, modifications, and improvements made without departing from the spirit and principles of the utility model should be covered within the scope of the utility model.
