no. 1 Embodiment approach

[0034] The first structure of a slide switch of a power supply transfer junction box in the present disclosure is as follows: Figure 6-7 As shown, the slide switch 13 is mainly composed of a circular vertical bar 13-1 and three horizontal bars 13-2. The top of the vertical bar is provided with a handle 13-7, wherein the three horizontal bars 13-2 are evenly distributed on the vertical bar 13. -1 and the distance between them is equal, the vertical bar 13-1 is an insulator, the cross bar 13-2 is a conductor with certain elasticity, the cross bar 13-2 can directly run through the vertical bar 13-1, and can also be connected The two ends are formed, so that the up and down sliding of the slide switch can realize the connection of the cross bar 13-2 and the protrusion on the L-shaped copper sheet, and realize the circuit connection of the copper sheet grooves on both sides. In order to realize the vertical connection of the vertical bar 13-1 Directional movement, a sliding track ...

Abstract

The invention discloses a power supply transfer junction box, which comprises a box body with a detachable upper cover. Multiple groups of plug interfaces are formed in the upper cover; the inner bottom surface of the box body is provided with multiple rectangular slots; each of two inner sides of the rectangular slot is provided with at least one copper sheet slot for placing a copper sheet; the copper sheet slot is internally provided with a plug interface passing through the bottom surface of the box body; a slide switch is arranged in the middle of the copper sheet slots at two sides; the slide switch moves vertically to contact the copper sheet, and thus, on or off of circuits at two sides is achieved; and a rail for enabling the slide switch to slide is arranged on the box body. According to the power supply transfer junction box provided in the invention, line transfer from normal mounting to unconventional mounting can be quickly realized, cutting of a motor lead can be effectively avoided, various problems caused by cutting of the lead are not generated, the power supply line reliability is improved; and besides, when the power supply transfer junction box is applied, an unconventional test can be carried out in any safety distance, occurrence of personal accidents is avoided, operation by a tester is facilitated, and system test requirements are met.

Description

technical field [0001] The disclosure belongs to a transfer junction box, in particular to a motor power supply transfer junction box. Background technique [0002] In some equipment power supply systems, each machine is powered by connecting the power supply plug connected to the machine stator to the corresponding socket of the power supply line slot. Multiple machines are installed as a whole to supply power through an independent line slot. In the current situation, two The frequency converter is loaded with multiple machines to start operation, and a switching box controls the power supply relationship between the frequency converter and the mounting frame. Inside. [0003] In the unconventional test, due to the certain danger of the test, in order to ensure the safety of personnel and equipment, it is necessary to lead the control line to a safe area to realize remote control. [0004] In the original test system, when such non-routine tests were required, all motor ...
