Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a junction box component. Background Art

[0002] The junction box is one of the electrical auxiliary materials. At the joint of the wire (for example, the line is relatively long, or the wire tube needs to turn a corner), the junction box is used as a transition. The wire tube is connected to the junction box, and the wires in the wire tube are connected in the junction box, which plays a role in protecting and connecting the wires. In building construction, the junction box is usually embedded in the wall of the construction. When the existing junction box is embedded in the construction, the metal wire box is generally directly welded to the wall steel bar, and the plastic junction box is connected to the wall steel bar by designing ear holes on the outer side of the junction box; the design of the junction box is to consider how to connect with the steel bar, and it cannot be well connected with the formwork. For the construction of plain concrete, if the junction box is installed on the wall steel bar, the vibration of the concrete and the fluctuation of the steel bar can easily cause the wire box to shift, so that the sealing between the wire box and the template installation surface is destroyed, resulting in leakage, water seepage around the wire box, etc., and serious color difference is reflected after the formwork is removed. In addition, since the strength of the wire box itself is generally not high, the wire box is prone to deformation during the concrete vibration process, which causes the sealing surface to shift, ultimately affecting the molding effect of the plain concrete surface.

[0003] Therefore, it is urgent to develop and design a new junction box structure, which is required to facilitate the direct installation of the junction box and the template, while ensuring the installation stability of the junction box and the template, and improving the molding effect of the plain concrete surface. Utility Model Content

[0006] Furthermore, the protrusion is extended toward one side of the bottom of the junction box and is adjacent to the bottom of the junction box.

[0007] Furthermore, the protrusion is an axially penetrating cylindrical structure.

[0008] Furthermore, the wire passing holes are evenly distributed in a plurality along the circumference of the junction box, and corresponding wire avoiding holes are provided on the cylinder wall of the raised portion corresponding to each wire passing hole.

[0009] Furthermore, the wire avoidance hole is a waist-shaped hole whose length is arranged along the depth direction of the junction box, and the waist-shaped hole is open at one end close to the bottom of the box.

[0010] Furthermore, the distance between the protrusion and the bottom of the junction box ranges from 5 mm to 20 mm.

[0011] Furthermore, a connection flange is provided at the box opening of the junction box, an annular groove is provided on the connection flange, and a sealing gasket is provided in the annular groove.

[0012] Furthermore, a plurality of raised columns are evenly distributed on the back of the connection flange along the circumference of the junction box, and a connection hole is provided at a position of the connection flange corresponding to each raised column, and the bottom of the connection hole does not penetrate the raised column.

[0013] Furthermore, the fastener passes through the connecting seat and the sealing gasket in sequence and is threadedly connected to the connecting hole.

[0014] Furthermore, a connecting pipe is fixedly sleeved inside the wire hole, and a sealing cover is screwed on the outer end of the connecting pipe.
