Detailed Description
Example 1
The insulating terminal connecting piece shown in fig. 1 comprises an outer frame 1 in a box-shaped structure, wherein a notch is formed in the top side wall of the outer frame 1, a sliding block 3 arranged at the notch, an inserting structure 2 below the outer frame 1, an upper limiting block 9 and a lower limiting block 10 in the outer frame 1 and two pin shafts 4 below the sliding block 3 are further included, and self-resetting springs 5 are fixed on the pin shafts 4; open on the 1 left side wall of frame and have loudspeaker form wire guide 6, 3 both ends of slider set up along the breach parallel and level, and its inside runs through has transversely to cross wire guide 7, goes up spacing 9 and sets up with its left end of spacing 10 and breach parallel and level down, goes up spacing 9 and constitutes the wire passageway 8 that holds electrified wire 14 between the spacing 10 down. The insulating terminal connecting piece further comprises a cover plate used for sealing the outer frame 1, and screw holes 11 used for installing the cover plate are formed in the upper limiting block 9 and the lower limiting block 10. The plug-in structure 2 is used for being connected with the guide rail type wiring terminal and comprises a plug-in column in the middle and tapered positioning pins on two sides. And the self-resetting spring 5 is welded below the pin shaft 4.
Example 2
Different from the embodiment 1, the bottom of the sliding block 3 is provided with a strip-shaped limiting block 12, the upper part of the lower limiting block 10 is provided with a limiting groove 13 in a matching way, and when the centers of the wire guide hole 6 and the wire passing hole 7 are overlapped, the limiting block 12 is contacted with the limiting groove 13.
The utility model discloses a working process is: as shown in fig. 2, in use, the cover plate is mounted on the base 1. Before the disconnection, the insulating terminal connecting piece is fixed on the corresponding guide rail type wiring terminal through the inserting structure 2. After the wires are removed, the wires are inserted into the insulated terminals to achieve insulation. Specifically, the self-resetting spring 5 is compressed by pressing the sliding block 3 by hand, so that the wire channel 8 is communicated with the wire passing hole 7 and the wire hole 6 (the hole centers are overlapped), the live wire 14 is inserted into the wire channel 8 from the wire hole 6 at the moment, the sliding block 3 is released to enable the self-resetting spring 5 to rebound, the wire channel 8 is dislocated with the wire passing hole 7 and the wire hole 6, and the live wire 14 is pressed and insulated from the outside. The potential safety hazards of workers and equipment are reduced.
