Problems solved by technology

[0005] The technical problem to be solved by the present invention is: in the prior art, the general wiring method is to remove the insulating skin at one end of the wire, deeply contact the conductive copper sheet through the wiring hole, and tighten the screw to complete the wiring. The protector solves the problem that the space between the coil and the screw is too large, which may cause loose contact between the coil and the conductive copper sheet and the current plate, and the space between the coil and the screw is too small, which may cause the screw to press the coil and the coil breaks.

Embodiment approach

[0031] As a specific embodiment of the present invention, a memory metal 17 is provided inside the insulating disk 7, and one end of the memory metal 17 is fixedly connected to the inner wall of the insulating disk 7, and the memory metal 17 elongates when heated;

[0032] During the energization process of the leakage protector body 1, heat will be generated when the wire is energized, and the memory metal 17 will be heated and elongated, and the wire will be squeezed after elongation, thereby achieving a good contact between the wire and the conductive plate 9 during the work process, and improving the power supply. Efficiency prolongs the service life of the wire, and there is a certain gap between the insulating disk 7 and the conductive disk 9 to provide a space for heat dissipation of the wire and reduce the probability of the wire being burned or short-circuited due to concentrated heat.

specific Embodiment approach

[0033] As a specific embodiment of the present invention, the outer surface of the conductive plate 9 is provided with anti-skid lines 18;

[0034] When the staff is wiring, after the wire passes through the wire wheel 20 and the threading groove 11, the wire contacts the conductive disc 9. During the staff's push, the anti-slip lines 18 on the outer surface of the conductive disc 9 produce friction, which reaches When the staff is wiring, the effect that the wire is not easy to slip off, thereby improving the wiring efficiency of the main body 1 of the leakage protector.

[0035] As a specific embodiment of the present invention, the inner walls on both sides of the insulating hole 13 are provided with lead rods 19, and the end of the lead rods 19 away from the insulating disc 7 is rotatably connected with a lead wheel 20;

[0036] When the staff is wiring, the wire passes through the wiring hole 5 and the insulating hole 13 successively. When passing through the insulating h...

Abstract

The invention belongs to the technical field of power equipment, and particularly relates to a leakage protector with an overload function. The bottom of the leakage protector body is provided with a wire holder, the bottom of the wire holder is provided with more than one wiring hole, and the top of the wire holder is provided with more than one threaded hole; more than one insulating disc is arranged in the wire holder, the adjacent insulating discs are separated by insulating rods, and the insulating discs are fixedly connected with the inner bottom of the wire holder; a conductive disc is arranged in the insulating disc, the conductive disc sleeves an electrifying column, the electrifying column is rotatably connected with the conductive disc, and the electrifying column is fixedly connected with the interior of the leakage protector body; one end of the conductive disc is provided with a threading groove and a wire blocking plate, an insulating hole is formed under the threading groove, and the insulating hole is formed in the insulating disc. According to the invention, through mutual cooperation of the conductive disc, the threading groove and the wire baffle plate, bending of the wire is completed, the bent wire is in contact with the conductive disc, wiring is completed, and the wiring efficiency of the leakage protector body is improved.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, in particular to an overload leakage protector. Background technique [0002] Leakage protector, commonly known as leakage switch, is a protector used to prevent personal electric shock and electrical fire when the circuit or electrical insulation is damaged and short-circuited to the ground. It is generally installed on the socket circuit of each household distribution box and the general power distribution of the whole building. The power supply line of the box has overload and short-circuit protection functions, but due to aging of electrical appliances, climate environment, human damage and other reasons, the normal power consumption is affected; [0003] In the prior art, the general wiring method is: remove one end of the insulation, touch the conductive copper sheet deeply through the wiring hole, and tighten the screw to complete the wiring. However, this wiring technology has ...
