Embodiment Construction

[0015] The present invention is specifically described below in conjunction with accompanying drawing, as shown in the figure, the present invention comprises terminal box seat 1, terminal block 3, terminal post 2, and terminal block 3 materials are pressed from unsaturated polyester plastic high-voltage insulation material (DMC); Terminal blocks with different heights are set on the terminal block; the terminal material is brass with grade H62 and the surface is silver-plated. The terminal is in the form of a terminal compression screw sleeve. The tight screw sleeve is connected with the terminal to realize the conduction function.

[0016] Use steps and cylindrical forms to ensure the electrical clearance and creepage distance of the main terminal.

[0017] The terminal adopts the upper and lower split form, including the lower column body 4 and the upper compression screw sleeve 5, the blind hole 51 is set under the compression screw sleeve 5, and the blind hole of the comp...

Abstract

The invention discloses a motor junction box structure which comprises a junction box base, a wire holder and binding posts, wherein the wire holder material is prepared by pressing an unsaturated polyester plastic high-voltage insulating material; the binding posts with different height are arranged on the wire holder; the material of the binding posts is made from H62 brass, and the surface is coated with silver; through a compaction thread insert manner of the binding posts, a cable is directly connected to a compaction thread insert and is connected with the binding posts through the compaction thread insert, a conductive function is realized. The motor junction box structure disclosed by the invention has the following advantages: the volume of the junction box is reduced; the wiringis realized directly by using a compaction screw instead of a wedging block, thus the wiring by the user is facilitated, and the operation performance of the motor is improved.

Description

technical field [0001] The invention relates to the field of motors, in particular to a universal junction box structure that realizes high power and small volume of the junction box. Background technique [0002] The explosion-proof three-phase asynchronous motors used in underground coal mines, as the space structure requirements become more and more strict, there are more and more motors requiring high power and small size, and the volume requirements for the space occupied by the junction box are also becoming more and more stringent. Generally, the junction box adopts the form of a junction box seat, a terminal board, and a terminal post. The terminal board is made of cast steel, and the terminal post is connected to the main cable in the form of a buckle. In order to ensure the electrical clearance and creepage distance, the junction box has a large space and a cumbersome structure. Moreover, junction boxes with different voltages and currents will use a large number ...
