Description

A kind of breaker of protection against electric shock wiring

Technical field

The utility model relates to the terminal devices of distribution system, control the control and protection with electric terminal for power supply, Refer specifically to a kind of breaker of protection against electric shock wiring.

Background technique

In wiring and maintenance process, staff is easy in the feelings for not disconnecting switch for distribution box and ammeter box internal switch Under condition, hot line job directly is carried out in the connecting part of leading-out terminal, is easy to happen the danger of electric shock.In the prior art, although there is guarantor Protection unit, but do not have outlet break prompt function, it cannot play the role of reminding whether staff has powered off, have one Fixed security risk.

Utility model content

The purpose of the utility model is to provide a kind of breakers of protection against electric shock wiring, and which solve protective devices not to have The problem of line break prompt function, the device have the function of that prompt disconnects switch, and can achieve prevents live line connection or maintenance The purpose of switch avoids the generation of electric shock accidents, improves the safety of field personnel.

The above-mentioned technical purpose of the utility model has the technical scheme that

A kind of breaker of protection against electric shock wiring, is made of switch, plug-in strip, safety cap, terminals, tether and fixed ring, Switch upper surface is provided with terminals, and terminals top is connected with safety cap, and safety cap bottom is provided with plug, and safety cap passes through Plug is inserted into terminals, one end connection of safety cap and tether, and the other end of tether ties up in fixed ring.

By adopting the above technical scheme, to carry out wiring, must extract safety cap manually could operate staff, extract Before safety cap, if do not powered off, safety cap is in lighting lamp state, prompts to need to disconnect switch, staff is according to safety cap Bright light prompt, plug-in strip is pulled to the position " OFF " and disconnects switch, after turning off the light occurs in safety cap, safety cap is pulled out from terminals Patching operations are carried out out, avoid the generation of electric shock accidents, while also preventing safety cap from falling or losing.

Further preferably are as follows: safety cap is internally provided with illuminator, and there is prompt to disconnect switching function, do not disconnect switch When be in lighting lamp state, in turning off the light state when disconnecting switch.

By adopting the above technical scheme, staff can be made intuitively to judge whether to power off, staff is prompted to disconnect switch, Achieve the effect that prevent live line connection, maintenance breaker.

Further preferably are as follows: illuminator is light emitting diode.

By adopting the above technical scheme, light emitting diode starting voltage is low, and stability is good, and photoelectric conversion rate is high, generates heat small, makes It is long with the service life, reduce on-site maintenance cost.

Further preferably are as follows: safety cap is made of resin material.

By adopting the above technical scheme, resin material has fire prevention, good insulating, intensity high, corrosion-resistant and resistant to high temperature Feature.

Further preferably are as follows: the safety cap is transparent type safety cap.

By adopting the above technical scheme, the safety cap of transparent type is convenient for staff more intuitively according to whether bright light judgement is No disconnection switch, improves operational safety.

Further preferably are as follows: one end of plug is connect with safety cap bottom, the other end and terminals grafting.

By adopting the above technical scheme, facilitate staff's insertion operation simple.

Further preferably are as follows: tether is tightrope.

By adopting the above technical scheme, tightrope flexibility is good, is easier to be tied in fixed ring, is not easy to fall and even lose, is Staff provides Maintenance and Repair and provides convenience.

Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5.

A kind of breaker of protection against electric shock wiring, live line connection or maintenance breaker for ammeter box and distribution box.

As shown in Figure 1, it includes switch 1, plug-in strip 2, safety cap 3, terminals 4, tether 5 and fixed ring 6.

Referring to Fig.1, which includes switch 1, plug-in strip 2, safety cap 3, terminals 4, tether 5 and fixed ring 6.Switch 1 Upper surface is provided with terminals 4, and 4 top of terminals is connected with safety cap 3, and 3 bottom of safety cap is provided with plug 31, safety cap 3 Terminals 4 are injected by plug 31, are provided with light emitting diode 32 in safety cap 3, safety cap 3 is connect with one end of tether 5, is The other end of rope 5 ties up in fixed ring 6, and 1 bottom of switch is provided with fixed ring 6.

Working principle: to carry out wiring, must extract safety cap 3 manually could operate staff, extract safety cap 3 Before, if do not powered off, the light emitting diode 32 in safety cap 3 will shine, and safety cap 3 is made to be in lighting lamp state, prompt to need Switch 1 is disconnected, plug-in strip 2 to the position " OFF " is first disconnected switch 1, safety cap 3 will according to the prompt of safety cap 3 by staff It is extracted from terminals 4 in the state of turning off the light, then by safety cap 3, back-outs terminal screw manually, finally carry out patching operations, Operation can effectively avoid electrification progress wiring and eliminate security risk to prevent the generation of electric shock accidents in this way.

This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but As long as within the protection scope of the present utility model all by the protection of Patent Law.
