Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. In order to distinguish the terminals, L-line, G-line, and N-line are used hereinafter, where L-line is a zero line, G-line is a ground line, and N-line is a live line.

The present embodiment provides a filter fixing device for a low voltage distribution room, as shown in fig. 1, the filter fixing device includes a filter with a male plug and a base adapted to the filter. In the present embodiment, the filter is provided with 5 pins, specifically, an L-line input pin 1, a G-line input pin 2, an N-line input pin 3, an L-line output pin 4, and an N-line output pin 5.

Set up a plurality of wiring holes and a plurality of slot on the side of base, the wiring hole is connected with the electricity of slot one-to-one, and the wiring hole is used for connecting switch board business turn over line. As shown in fig. 2A and 2B, the right side of the base is provided with 5 slots, including: an N-line input slot 6, a G-line input slot 7, an L-line input slot 8, an N-line output slot 9 and an L-line output slot 10; the pins can be inserted into the corresponding slots. The wiring hole is divided and is established in the upper and lower both sides of base, and wherein, the base upside sets up the wiring hole of 3 inlet wires: n line entrance hole 21, G line entrance hole 22, L line entrance hole 23, the base downside sets up 2 wiring holes of being qualified for the next round of competitions: an N-line outlet hole 24 and an L-line outlet hole 25. The 5 wiring holes and the 5 slots are electrically connected in one-to-one correspondence inside the base through conductive parts, wherein the conductive parts can be wires, but are not limited to wires, and can also be other conductive parts.

In order to facilitate the switch board business turn over line fixed to the wiring hole, set up a plurality of fixed screws on the base, fixed screw perpendicular to wiring hole sets up. The wire inlet and outlet device specifically comprises an N-wire inlet wire fixing screw 15, a G-wire inlet wire fixing screw 16, an L-wire inlet wire fixing screw 17, an N-wire outlet wire fixing screw 18 and an L-wire outlet wire fixing screw 19.

In order to make the base dismouting of being convenient for, the base can be dismantled with the switch board and be connected. Wherein, the detachable connection can be a threaded connection, as shown in fig. 2A, the base is provided with 4 screw fixing ports 11, 12, 13, 14 for connecting fixing screws. The detachable connection can also be a guide rail connection, as shown in fig. 2A, the base is provided with a groove which can be connected with a track in the power distribution cabinet, and the base is provided with a buckle 20 and is connected to the base through the buckle.

During the use, the buckle 20 of base is drawn outward to the hand, hangs the base on the guide rail of switch board, loosens buckle 20 to unable adjustment base, and available screw passes through the screw fixation mouth and further fixes the base.

The wires in the power distribution cabinet are correspondingly connected to 5 wiring holes (an N-wire inlet hole 21, a G-wire inlet hole 22, an L-wire inlet hole 23, an N-wire outlet hole 24 and an L-wire outlet hole 25), and the wires are fixed by screws (an N-wire inlet wire fixing screw 15, a G-wire inlet wire fixing screw 16, an L-wire inlet wire fixing screw 17, an N-wire outlet wire fixing screw 18 and an L-wire outlet wire fixing screw 19) so as to be stably connected.

When the filter is used, five pins of the filter male plug, namely an L line input pin 1, a G line input pin 2, an N line input pin 3, an L line output pin 4 and an N line output pin 5 are inserted into five slots on the base, namely an L line input slot 8, a G line input slot 7, an N line input slot 6, an L line output slot 10 and an N line output slot 9, in a one-to-one correspondence manner, and then the filter can be used.
