Description

Technical Field

[0001] This utility model relates to a side-fixed junction box connector. Background Technology

[0002] In modern home renovations, wiring is typically buried within the walls. The wiring throughout the house is often complex, sometimes requiring cable splitting or merging. This necessitates protecting the cable joints; simply burying them directly in the wall is detrimental to cable protection and use, and also hinders future maintenance. Cables are usually sheathed or encased in metal, making the joints prone to damage, thus requiring consideration of future repairs. The current solution involves installing a junction box, typically a square metal box with small holes on the side for cable insertion. However, these junction boxes have pre-set openings; a slight press at the opening removes the metal plate. These openings often have burrs and rough edges, which can easily scratch and damage the cable if inserted directly. Utility Model Content

[0003] The present invention aims to solve the technical problems existing in the prior art, thereby providing a side-fixed junction box connector that is simple in structure and easy to operate.

[0004] The above-mentioned technical problems of this utility model are mainly solved by the following technical solutions:

[0005] This utility model discloses a side-fixed junction box connector, including a main housing, which is made of galvanized sheet by stamping; a cable outlet is provided at one end of the main housing; the other end has a symmetrical design with an upper pressure plate and a lower pressure plate extending vertically outward on the side; a movable pressure member is provided on the inner side of the lower pressure plate; the upper and lower pressure plates are in the shape of a "7", with one end extending vertically from the circular side of the main housing, and the other end overlapping each other to form a support component.

[0006] Preferably, corresponding openings are provided on the upper end of the upper pressure plate and on the main housing according to the width of the upper and lower pressure plates.

[0007] Preferably, the main housing has an outwardly protruding annular ring above the opening.

[0008] Preferably, the main housing is fitted with an outer ring buckle at one end near the cable outlet for securing the connector when it is inserted into the junction box.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0022] like Figure 1-3As shown, a side-fixed junction box connector is mainly used to fit onto a wire and snap into a junction box, both to fix the wire and to prevent direct friction between the wire and the junction box. It includes a main housing 1, which is stamped from galvanized sheet. One end of the main housing 1 has a wire outlet 3; the other end has a symmetrical design with an upper pressure plate 8 and a lower pressure plate 9 extending vertically outwards. A movable pressure member 5 is provided inside the lower pressure plate 9. Specifically, the main housing 1 is a hollow cylinder, with the end near the upper and lower pressure plates serving as the wire inlet, allowing the wire to be inserted and exit through the outlet 3. It should be noted that during use, a flexible tube can be fitted over the wire to protect it, with the pressure member 5 pressing against the tube. The wire end exiting from the outlet 3 is the end of the wire inside the tube; alternatively, it can be used directly with the wire. The upper and lower pressure plates are "7"-shaped, with one end extending vertically from the circular side of the main housing 1, and the other ends overlapping to form a support component.

[0023] An opening 7 is provided on the upper end of the upper pressure plate 8 and the main housing 1 according to the width of the upper and lower pressure plates; in other words, an opening is made in the main housing 1 above the upper pressure plate 8 and the symmetrically arranged lower pressure plates 9.

[0024] Above the opening 7, the main housing 1 has an outwardly protruding annular protrusion 2; specifically, the main housing 1 is generally cylindrical, but an annular protrusion protrudes outward above the opening 7. When the connector is inserted into the junction box during use, it will be locked by the protrusion 2 as a limit, preventing the connector from being mispositioned, over-locked, or falling out of the junction box during use.

[0025] The main housing 1 is fitted with an outer ring buckle 4 at one end near the outlet 3 for fixing the connector when it is inserted into the junction box. There is an elastic piece on the outer ring buckle 4 to prevent the connector from falling off after it is inserted into the junction box. For details, please refer to the patent CN221805919 of this application. Since the outer ring buckle is the same as the outer ring buckle of the connector product previously applied for by the applicant, the applicant will not describe the outer ring buckle 4 in detail here.

[0026] The pressing component 5 includes an arc-shaped pressing plate 5.2, a limiting plate 5.1 perpendicular to the pressing plate 5.2, and a screw 6 penetrating the pressing plate 5.2.

[0027] An upwardly protruding boss 5.3 is provided at the connection between the pressure plate 5.2 and the screw 6 to make the connection of the screw 6 more secure and less prone to slippage; furthermore, the screw 6 is fixed on the pressure plate 5.2, so rotating the screw 6 can move the pressure plate 5.2 up and down, and it can also be fixed by the thread when the screw 6 is not rotated.

[0028] The pressure plate 5.2 is located inside the main housing 1. Specifically, after the wire is inserted into the main housing 1, the pressure plate 5.2 is pressed directly onto one side of the wire by rotating the screw 6 until the other side of the wire abuts against the inner wall of the main housing 1. In this way, one side is the inner wall of the main housing 1, and the other side is the pressure plate 5.2, which is fixed by the screw 6, thereby achieving the effect of fixing the wire to the connector.

[0029] The limiting plate 5.1 extends out from the opening 7. Specifically, we first put the pressure plate 5.2 and the limiting plate 5.1 into the main housing, and then fold the upper and lower pressure plates together. In this way, the limiting plate 5.1 extends out from the opening 7. When the screw 6 is turned to move the pressure plate 5.2, the limiting plate 5.1 is just stuck at the opening 7, which ensures that the pressure plate 5.2 is limited and will not change its direction of movement.

[0030] The screw 6 passes through the upper pressure plate 8 and the lower pressure plate 9 and is connected and fixed to the pressure plate 5.2. Furthermore, by rotating the end of the screw 6 located on the outside of the upper and lower pressure plates, the pressure plate 5.2 can be moved within the main housing 1. This side-fixing method allows the connector to be used with wires of various sizes.

[0031] The upper pressure plate 8 and the lower pressure plate 9 are both galvanized sheets with a thickness of 0.8-1.0 cm. Furthermore, the superimposed design of the upper and lower pressure plates plays a supporting role, avoiding insufficient rigidity when the screw 6 passes through, so as to obtain more effective support and stabilize the thread fixing.

[0032] The beneficial effects of this utility model are:

[0033] The overlapping design of upper and lower pressure plates makes the threaded connection more stable; the pressure piece fixes the wire from the side, which allows the connector to be used with more wire sizes and expands its applicability; at the same time, the structure of screws and arc-shaped pressure plates achieves a simple and easy-to-operate structure; and the design of the limiting plate ensures that the pressure piece will not deviate from the expected range when moving, improving the wire fixing effect.
