Description

Technical Field

[0001] This utility model belongs to the field of connector technology, specifically, it relates to a connector for a junction box. Background Technology

[0002] A junction box is a device used to protect wires and cables, typically installed in walls, floors, or ceilings so that wires can safely pass through these structures without damage. A connector is located on the side of the junction box, with a through-hole for the power supply wire to pass through.

[0003] The connectors used in existing junction boxes usually have a clamping structure inside the wire hole for fixing the wire. Most of them hold the wire in place after it passes through the wire hole, relying on friction to fix it. This type of clamping structure is relatively simple and widely used. However, most of the existing clamping structures are integrated on each connector and cannot be disassembled. On the one hand, for the sake of production, only one clamping structure can be set on each connector, and the stability of clamping and fixing the wire is generally not very good. On the other hand, if the clamping structure is damaged, the entire connector needs to be replaced, which is inconvenient. Summary of the Invention

[0004] Existing junction boxes use connectors with only one clamping structure for securing wires, which cannot be removed, affecting the stability of wire securing and making it impossible to replace the clamping structure if it is damaged. The following utility model is proposed:

[0005] A connector for a junction box includes a connector body with a wire hole inside. A wire passes through the wire hole, and a first clamping member and a second clamping member are sleeved on the outside of the wire. One end of the first clamping member and the second clamping member are provided with a mating part that is threadedly connected to the wire hole. A first clamping plate extends from the other end of the first clamping member to clamp the wire, and a second clamping plate extends from the other end of the second clamping member to clamp the wire.

[0006] Furthermore, the first clamping plate is provided in a plurality of them and arranged in a ring on the first clamping member. The first clamping plates are separated by a first partition groove. The ends of adjacent first clamping plates retract and approach each other in the extending direction to clamp the wire.

[0007] Furthermore, the second clamping plates are provided in a plurality of them and arranged in a ring on the second clamping member. The second clamping plates are separated from each other by a second partition groove. The ends of adjacent second clamping plates retract and approach each other in the extending direction to clamp the wire.

[0008] Furthermore, the first and second partition grooves are staggered from each other in the horizontal direction.

[0009] Furthermore, the first clamping plate has a first clamping block that contacts the wire on its inner side; the second clamping plate has a second clamping block that contacts the wire on its inner side.

[0010] Furthermore, the first clamping member has a first mating hole in the shape of a prism on the inner side of its mating part; the second clamping member has a second mating hole in the shape of a prism on the inner side of its mating part.

[0011] This utility model proposes a connector for a junction box. Its advantages are that it has multiple clamping components that act as clamping structures and are threadedly connected to the connector body. On the one hand, the multiple clamping components have a good clamping and fixing effect on the wires. On the other hand, the threaded connection allows the operator to replace the clamping components when they are damaged, which is more convenient. Attached Figure Description

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments.

[0018] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0019] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing the present invention and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0020] In addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also indicate a certain dependence or connection relationship in some cases. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0021] like Figures 1-2 As shown, this is a preferred embodiment of the present invention. A connector for a cable box includes a connector body 1, a cable hole 11 inside the connector body 1, a horizontally passing wire inside the cable hole 11, and a first clamping member 2 and a second clamping member 3 sleeved on the outside of the wire. One end of the first clamping member 2 and the second clamping member 3 is provided with a mating part 21. The outer side of the mating part 21 is provided with an external thread, and the inner sidewall of the cable hole 11 is provided with an internal thread that matches the external thread, so as to thread the first clamping member 2 and the second clamping member 3 into the cable hole 11. At the other end of the first clamping member 2, a first clamping plate 4 extends horizontally. During the horizontal extension of the first clamping plate 4, its end is inclined toward and contacts the wire. Similarly, at the other end of the second clamping member 3, a second clamping plate 5 extends horizontally. During the horizontal extension of the second clamping plate 5, its end is inclined toward and contacts the wire.

[0022] When using it, the first clamping member 2 and the second clamping member 3 need to be threaded into the wire hole 11 first, and then the wire is passed through the through hole in the center of the first clamping member 2 and the second clamping member 3. During this process, the clamping plate will first contact the wire and move outward. After the wire has completely passed through the clamping member, the clamping plate will move inward and clamp the wire.

[0023] Furthermore, the first clamping member 2 has multiple first clamping plates 4 arranged in a ring on the first clamping member 2, and the first clamping plates 4 are separated by a first partition groove 41. The ends of all the first clamping plates 4 gradually contract and converge towards each other in the extending direction. The second clamping member 3 has multiple second clamping plates 5 arranged in a ring on the second clamping member 3, and the second clamping plates 5 are separated by a second partition groove 51. The ends of all the second clamping plates 5 gradually contract and converge towards each other in the extending direction. During the process of the wire passing through the clamping member, both the first clamping plates 4 and the second clamping plates 5 expand outward and then contract inward again to clamp and fix the wire. In addition, in this embodiment, the first partition groove 41 and the second partition groove 51 are staggered from each other in the horizontal direction, so that the positions of the first clamping plates 4 and the second clamping plates 5 clamping the wire in the horizontal direction are also staggered, avoiding the clamping of the wire being concentrated in a certain horizontal direction, thereby improving the stability of the wire clamping and fixing.

[0024] Furthermore, the inner side of the first clamping plate 4 is provided with a first clamping block 42 that contacts the wire; the inner side of the second clamping plate 5 is provided with a second clamping block 52 that contacts the wire, and the first clamping block 42 and the second clamping block 52 replace the clamping plates to clamp the wire; for example Figure 3 As shown, the inner side of the mating part 21 of the first clamping member 2 is provided with a first mating hole 22 in the shape of a hexagonal prism; the inner side of the mating part 21 of the second clamping member 3 is provided with a second mating hole 31 in the shape of a hexagonal prism. After inserting a tool that is compatible with the first mating hole 22 and the second mating hole 31, the first clamping member 2 and the second clamping member 3 can be screwed in and out, and the distance between them can be controlled.

[0025] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
