Description
Technical field
The utility model is related to a kind of protection against electric shock test pencils.
Background technology
Test pencil is the Simple tool for measuring object and whether charging.Traditional test pencil generally includes to connect with object under test
Tactile pen tip metallic object, insulation pen body（Inner cavity includes current-limiting resistance, neon tube, spring etc.）With hand touched electrode.In use, by pen tip
Metallic object touches testee, human contact's hand touched electrode, using human body as earth conductor, when testee has higher voltage
When, neon tube is bright, shows that object under test charges.But using human body as earth conductor, there are security risks, if accidentally touching high pressure belt
Electric body will lead to electric shock accidents, jeopardize personal safety.
Utility model content
The purpose of this utility model is that according to prior art shortcoming and to provide a kind of safety good, practicability compared with
Strong protection against electric shock test pencil.
For this purpose, the utility model uses following technical scheme：
A kind of protection against electric shock test pencil, including test pencil bar, pen body and the indicator in pen body, test pencil bar are to lead
Electric material, one end are detection end, and the other end is located at the inner cavity of pen body, the tail portion of the pen body cavity be equipped with metallic conduction piece,
Elastic conducting electric pole, metallic conduction head and insulated enclosure lid, metallic conduction piece are fixedly connected on pen body, and elastic conducting electric pole is fixedly connected
In metallic conduction piece, elastic conducting electric pole end is connected with metallic conduction head, and metallic conduction head is embedded in insulated enclosure and covers.
Further, the elastic conducting electric pole has elasticity, is in the curved shape of spring-like in its natural state.
Further, elastic conducting electric pole periphery is coated with insulating outer layer.
Further, the metallic conduction head is in cone shape or round estrade shape, and cone or section end are located at the chamber of pen body
In vivo, and bottom surface is located at outside the cavity of pen body.
The beneficial effects of the utility model have：
The utility model proposes a kind of protection against electric shock test pencil, by elastic conducting electric pole and metallic conduction head instead of previous
Hand touched electrode.When determination is safer, operator can be in direct contact metallic conduction head with hand, be that ground connection is led with human body
Body so that power supply, test pencil, human body and ground constitute galvanic circle；It is uncertain whether it is safe when, can also be by metallic conduction
Head pulls out pen body inner cavity together with elastic conducting electric pole, holds the insulating layer of elastic conducting electric pole periphery cladding, metallic conduction head is touched
The natural low potential object such as wall so that power supply, test pencil and wall constitute galvanic circle, avoid electric current by human body, protect
The safety of operator is demonstrate,proved.Meanwhile elastic conducting electric pole is sealed in pen body by insulated enclosure lid, does not influence the appearance of test pencil.
Description of the drawings
