A bamboo-shaped free-steering junction box

Abstract

The present invention relates to a bamboo-shaped free turning junction box. The bamboo-shaped free turning junction box comprises an insulated center cylinder and a plurality of outer cylinders rotationally sleeving on the center cylinder in order; three first raised lines are arranged at the outer portion of the center cylinder along the axis direction; the three first raised lines perform equal division of the outer circumference of the center cylinder; the outer surface of the center cylinder between two adjacent first raised lines is provided with arc first conducting strips; three second raised lines are arranged at the inner circles of the outer cylinders; the three second raised lines perform equal division of the circumference of the inner circles of the outer cylinders; the second raised lines are coated with second conducting strips; the second conducting strips are in respective sliding electrical contact with the first conducting strips; the center cylinder is provided with a main firing line hole, a main null line hole and a main ground wire hole along the axis direction; and the outer cylinders comprise branch firing line holes, branch null line holes and branch wire holes along the radial direction of the outer cylinders. The bamboo-shaped free turning junction box can allow each branching to have a free rotation angle approach to 120 degrees to facilitate wiring, and has moistureproof, waterproof and convenient dismounting and mounting, and the service life of the wire is long.

Description

technical field [0001] The invention relates to a bamboo-shaped free-steering junction box, which belongs to the field of electric wire connectors. Background technique [0002] The junction box is one of the electrical accessories, generally used as a transition, used in the wiring or branching part, to protect the wires and connect the wires; the junction box is widely used in various fields, and it is essential for circuit design and layout In the field of engineering, it is often necessary to set up branches for the main line. The main line needs to be divided into several sub-lines, and the sub-lines generally lead to different directions. The existing junction box does not have a steering device, and it relies on wires to bend and turn directly.

[0002] The junction box is one of the electrical accessories, generally used as a transition, used in the wiring or branching part, to protect the wires and connect the wires; the junction box is widely used in various fields, and it is essential for circuit design and layout In the field of engineering, it is often necessary to set up branches for the main line. The main line needs to be divided into several sub-lines, and the sub-lines generally lead to different directions. The existing junction box does not have a steering device, and it relies on wires to bend and turn directly. It will cause extra stress on the wire connection part, and it is easy to loosen and break the wire connection part, and the engineering cables are generally thicker, and the bending of the cable is inconvenient and requires a larger turning radius, which increases the occupied space

[0003] The wiring of most junction boxes generally adopts the method of tightening screws to fix the wires, which is not only easy to damage the wire connection part, but also inconvenient to install and disassemble; especially for engineering fields that require frequent disassembly, the life of the wire connection part is short

[0004] In addition, the general environment in the engineering field is poor, and there are generally unfavorable environments such as humidity. Most junction boxes cannot be waterproof and moisture-proof, and some junction boxes with waterproof functions are relatively thick and have a small space inside the box.
