Description

Improved junction box

Technical Field

The utility model belongs to the technical field of junction boxes, and particularly relates to an improved junction box.

Background

Junction boxes are common electrical connectors in everyday life. Existing junction boxes typically require grounding when in use. The common grounding mode of the junction box is that a screw hole is formed in a bottom plate of the junction box, and a grounding wire is fixed by screwing a screw into the screw hole. This causes the front end of the screw to protrude outside the junction box, thereby causing inconvenience in installation of the junction box. Improvements are needed for this purpose.

Disclosure of Invention

The utility model aims to provide an improved junction box so as to solve the inconvenience caused by the fact that the screw for fixing the grounding wire protrudes out of the junction box.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:

the utility model provides an improved terminal box, the terminal box is upper end open-ended box body, including bottom plate and curb plate, the through wires hole has all been seted up on bottom plate and the curb plate, and the upper end opening part of box body is equipped with the ear for through the screw fixation panel, the position of earth connection is protruding upwards to form ascending convex closure on the bottom plate, just the top of convex closure is equipped with the screw that is used for fixed earth connection.

Preferably, the height of the convex hull is 3-5 mm.

According to the utility model, the threading hole is provided with the baffle, and the outer edge of the baffle is connected with the inner edge of the threading hole through spot welding.

According to the utility model, the side plates are spliced into a square shape, and four corners of the spliced part are arc-shaped.

According to the utility model, the pair of lugs are arranged on two opposite arc-shaped corners and are formed by bending into the box body, and screw holes are formed in the lugs.

Further, the two sides of the lug part are also provided with concave parts.

Preferably, the bottom plate is provided with one or more fixing holes.

The utility model has the following beneficial effects:

1. according to the utility model, the convex hulls protruding upwards are arranged at the positions of the grounding wires on the bottom plate of the junction box, so that the front ends of the screws for fixing the grounding wires are positioned in the convex hulls, and inconvenience brought to the installation of the junction box due to the fact that the screw is protruded out of the junction box is avoided.

2. The sunken setting in ear both sides not only is convenient for the shaping of buckling of ear, also can avoid the high upper end open-ended height of terminal box to influence the installation of panel after the ear is buckled in to the box simultaneously.

Drawings

Fig. 1 is a schematic structural view of the improved junction box of the present utility model.

Description of the figure:

1-a bottom plate; 2-side plates; 3-threading holes; 4-ear; 5-convex hull; 6-screw holes; 7-a baffle; 8-recessing; 9-fixing holes.

Detailed Description

The technical scheme of the utility model is clearly and completely described in the following by specific embodiments with reference to the accompanying drawings. It should be understood that the described embodiments are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

As shown in fig. 1, a schematic structure of the improved junction box of the present utility model is shown. As shown in the figure, the junction box is an upper end open-ended box body, and comprises a bottom plate 1 and a side plate 2, threading holes 3 are formed in the bottom plate 1 and the side plate 2, and ears 4 are arranged at the upper end opening of the box body and are used for fixing a panel (not shown in the figure) through screws.

An upward bulge is arranged at the position of the grounding wire on the bottom plate 1, so that an upward bulge 5 (an upward groove is formed when the bottom surface of the bottom plate 1 is seen) is formed on the bottom plate 1, and a screw hole 6 for fixing the grounding wire is formed at the top end of the bulge 5; thus, after the screw of the grounding wire is screwed into the screw hole 6 to fix the grounding wire, the front end penetrating out of the box bottom cannot protrude out of the plane where the bottom plate 1 of the junction box is located due to the existence of the convex hull 6, so that inconvenience in installation of the junction box is avoided. Preferably, the height of the convex hull 6 is 3-5 mm.

Further, a baffle plate 7 is arranged on the threading hole 3, and the outer edge of the baffle plate 7 is connected with the inner edge of the threading hole 3 through spot welding so as to block the threading hole 3; when threading is needed, the spot welding fixation is released, and the baffle 7 is removed.

Furthermore, the side plates 2 of the junction box are spliced into a square shape, and four corners of the spliced part are arc-shaped. The pair of ears 4 are disposed on two opposite arc corners and are formed by bending into the box body, and screw holes 6 are formed in the ears 4 for mounting a panel (not shown) by means of screws. Preferably, the both sides of ear 4 still are provided with sunken 8, and the shaping of buckling of ear 4 on the one hand of being convenient for, on the other hand can make the ear 4 highly not surpass the open-ended height in upper end of terminal box after buckling in the box to avoid the unevenness after the panel installation.

Further, the base plate 1 is further provided with one or more fixing holes 9, so that the junction box can be fixed on the vertical surface of an ungrooved wall or column, and the outer surface of a ceiling (suspended ceiling).

Although the structure of the junction box of the present utility model is described in detail above by way of specific embodiments, it should not be construed as limiting the utility model. It should be understood that modifications, substitutions and further improvements may be made by those skilled in the art in light of the above disclosure, but any modifications or equivalents are intended to fall within the scope of the present utility model.
