Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Please refer to figure 1 , The anti-shock wiring device of the first embodiment includes: an insulating base 1 and a locking screw 2 .

[0027] The insulating base 1 has an accommodating cavity 11 , two opposite side walls of the accommodating cavity 11 are respectively provided with wire holes 12 , and the top wall of the accommodating cavity 11 is provided with an assembly hole 13 .

[0028] The locking screw 2 is installed in the assembly hole 13, and one end extends into the accommodating cavity 11, and presses the plurality of sheet-shaped wires 3 that enter the accommodating cavity 11 from the wire hole 12. tightly fastened together and electrically connected.

[0029] It is especially important that the locking screw 2 is composed of a screw head 21 and a screw seat 22, the material of the screw head 21 is metal, and the material of the ...

Abstract

The invention discloses an anti-electric-shock wiring device and a circuit breaker adopting the same. The anti-electric-shock wiring device comprises an insulated base body and a locking screw rod, wherein the insulated base body has an accommodating cavity, wire holes are formed in two opposite side walls of the accommodating cavity, and an assembling hole is formed in the top wall; the locking screw rod is mounted in the assembling hole, and one end portion extends into the accommodating cavity, so as to fix a plurality of lead wires entering the accommodating cavity from the wire holes together and electrically connect the lead wires; the locking screw rod is composed of a screw rod head and a screw rod base, the screw rod head is made of metal, and the screw rod base is made of an insulating material. Wire incoming terminals and wire outgoing terminals of the circuit breaker adopt the anti-electric-shock wiring devices. When in use, currents on the lead wires are not conducted to an outer leakage portion of the locking screw rod, such that electric shock cannot occur even if a person is in contact with the outer leakage portion of the locking screw rod inadvertently, thus the wiring device is safe to use, and the assembling hole can be formed shallowly and does not require an additional protective cover plate.

Description

technical field [0001] The invention relates to a wiring device, in particular to an electric shock-proof wiring device and a circuit breaker using the wiring device. Background technique [0002] The small distribution box for indoor power supply is usually embedded in the wall and consists of a main switch (circuit breaker) and at least one sub-switch (circuit breaker). The external power supply enters each sub-switch through the main switch and is then distributed to different electrical appliances. , such as lighting equipment, air conditioners, refrigerators, etc. There is a terminal on each switch, and the locking screw of the terminal is in contact with the connected wire, so it has high voltage. Once it touches the human body, it will be life-threatening. [0003] In order to avoid electric shock due to contact with the locking screw on the terminal, there are two methods currently used: one is to make the assembly hole for the locking screw deeper to make it diffic...
