Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments.

First embodiment

Referring to fig. 1, fig. 2, and fig. 3, the bus duct monitoring tap unit includes:

a housing 1;

the pins 2, at least four pins 2 are arranged on one side of the shell 1;

the through groove 3 is formed in the pin 2, the limiting blocks 4 are connected between two sides of the inside of the through groove 3 in a sliding mode, and a limiting spring 5 is arranged between one opposite sides of the two limiting blocks 4;

the arc-shaped face 6 is arranged on the limiting block 4.

The top of shell 1 is provided with radiator-grid 7, be connected with axis of rotation 8 on the radiator-grid 7, the surface of axis of rotation 8 rotates and is connected with apron 9, the bottom of apron 9 is provided with cleaning brush 10. The arc-shaped surface 6 is arranged, so that the limiting block 4 and the plug pins can conveniently enter the slot together, and connection is finished;

spacing spring 5's setting, when kick-backing, promotes stopper 4 and extrudees the slot, increases to participate in 2 and slot connection's fastness, avoids taking place not hard up.

The setting of apron 9 for when maintaining the bus duct, avoid not adhesion dust on the unit radiator-grid 7 that operates, and then influence the heat dissipation, thereby play the effect of sheltering from.

The cleaning brush 10 is arranged to sweep and clean the surface of the heat radiating net 7 when the cover plate 9 is repeatedly rotated, so as to achieve the effect of cleaning ash.

The cover plate 9 and the heat dissipation net 7 are both circular in shape and are matched with each other. The cover plate 9 makes the cleaning brush 10 contact and rub on the surface of the heat dissipation net 7 in the rotation process, so as to clean the heat dissipation net 7. The left side of the top of the cover plate 9 is provided with a push handle 11 for controlling the movement of the cover plate 9.

When the plug pin 2 is connected with a slot (not shown) on the bus duct connector, the arc-shaped surface 6 on the limiting block 4 is driven to firstly slide into the slot at the joint and continue to be inserted, so that the limiting block 4 is extruded, the limiting spring 5 is driven to extrude until the limiting block 4 is completely inserted, the limiting spring 5 is driven to compress and deform, and after the connection is finished, the limiting block 4 is pushed to extrude the slot under the rebound of the limiting spring 5, so that the firmness of the joint is improved, the looseness is avoided, and the use of the bus duct is further influenced;

when the tapping unit is using, through the radiator-grid 7 that sets up, release the heat, wherein, when maintaining or overhauing, the tapping unit does not operate this moment, in order to avoid great dust to fall into on the radiator-grid 7 to influence the heat dissipation, through pushing away control handle 11, drive apron 9 and rotate, make apron 9 cover on the radiator-grid 7, thereby realize the sheltering from to radiator-grid 7.

through stopper 4 and the spacing spring 5 that sets up, when participating in 2 and inserting inside the slot, through spacing spring 5's resilience, promote stopper 4 and extrude the inner wall of slot, improve and participate in the fastness of being connected between 2 and the slot, avoid frequent pulling out and insert down, make the fastness of connecting descend, the condition that electric power interrupted appears easily takes place, and then has improved the practicality of this unit.
