Abstract
The utility model relates to a pair of pliers with a voltage test function, which comprises plier bodies (1). The utility model is characterized in that a shell (6) for a voltage test device, a luminous diode (3), a resistor (2), a rubber resistor (5), a needle type electrode (4) and another needle type electrode (7) singly combined with a plier handle are installed on a plier handle of each of the plier bodies, and the luminous diode (3), the resistor (2), the rubber resistor (5), the needle type electrode (4) and another needle type electrode (7) singly combined with the plier handle are arranged in the shell (6), wherein one end of the luminous diode (3) is penetrated through an insulating bush and is electrically connected with each plier handle, and the other end thereof is connected with the resistor (2); the other end of the resistor (2) is respectively connected with the rubber resistor (5) and the needle type electrode (4); the needle type electrode (7) is penetrated through the insulating bush and is electrically connected with each plier handle. The utility model not only can be used as a pair of joint pliers but also can be used as a test pencil; furthermore, the utility model can realize the purpose of checking failure among wires on the premise that an insulation layer is not stripped.
Description
Technical field
The utility model relates to a kind of electrician's instrument, relates to a kind of hand vice with examination electric work energy specifically.
Background technology
Voltage test pencil is one of indispensable instrument of maintenance circuit, detection.The voltage test pencil that simple function is not only arranged in the voltage test pencil of prior art also has the multi-functional voltage test pencil that combines with hand vice.But the voltage test pencil of said structure can only detect the metal wire that exposes to the open air outside insulating materials usually.That is to say, if adopt the voltage test pencil of prior art that trouble point between line is detected, then must will just can carry out after the insulation displacement of electric wire, and for the two cover of twin-core cable, not only its detection difficulty strengthens, and also can cause broken largely ring to cable.
Summary of the invention
The purpose of this utility model just at existing deficiency in the above-mentioned prior art and provide a kind of can under the prerequisite of not broken looped cable insulating barrier to line between the trouble point detect have the examination electric work can hand vice.
The purpose of this utility model can realize by following technique measures:
Hand vice with examination electric work energy of the present utility model comprise caliper, on the pincers handle of caliper, the Electric tester housing are installed, are arranged on light emitting diode, resistance, rubber resistance, needle electrode in the housing, and the needle electrode that combines with the pincers handle separately; One end of described light emitting diode penetrates insulation sleeve and directly is electrically connected with the pincers handle, and the other end is connected with resistance; The other end of resistance is connected with needle electrode with rubber resistance respectively; Needle electrode penetrates insulation sleeve and directly is electrically connected with the pincers handle.
The utility model also can adopt following concrete measure to realize, inboard at pincers of caliper handle is equipped with light emitting diode, resistance, rubber resistance and needle electrode by the Electric tester housing, and needle electrode is installed in the inboard of another pincers handle of caliper with respect to needle electrode.
The utility model also can adopt following concrete measure to realize, and the Electric tester housing is arranged, be arranged on light emitting diode, resistance, rubber resistance, needle electrode in the housing in installed inside that clamps handle of caliper, and the needle electrode that combines with the pincers handle separately.
The purpose that rubber resistance is set in the utility model is to reduce voltage, reduces electric current to the injury that human body may cause, and avoids the generation of contingency.
The utlity model has the two of examination electricity and hand vice from function, can be used as hand vice at ordinary times uses, when fault detects between needs are to line, only need two needle electrodes that are provided with are relatively aimed at cable, and by exerting pressure to the pincers handle, needle electrode insulation-piercing layer is contacted with metal wire, be implemented under the prerequisite that need not peel off insulating barrier, the purpose that fault between line is searched.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is circuit theory diagrams of the present utility model.
Fig. 3 is the front view of another embodiment of the utility model.
LED is a light emitting diode among Fig. 2, and R1 is a resistance, and R2 is a rubber resistance.
The specific embodiment
The utility model is further described below with reference to embodiment (accompanying drawing):
As shown in Figure 1, 2, the hand vice that the utlity model has examination electric work energy comprise caliper 1, inboard at pincers of caliper handle is equipped with light emitting diode (LED) 3, resistance (R1) 2, rubber resistance (R2) 5, needle electrode 4 by Electric tester housing 6 (adopting transparent material to be made), in another installed inside that clamps handle of caliper needle electrode 7 is arranged; One end of described light emitting diode (LED) 3 penetrates insulation sleeve and directly is electrically connected with the pincers handle, and the other end is connected with resistance (R1) 2; The other end of resistance (R1) 2 is connected with needle electrode 4 with rubber resistance (R2) 5 respectively; The needle electrode 7 that is positioned at another pincers handle inboard of caliper penetrates insulation sleeve and directly is electrically connected with the pincers handle.
Fig. 3 is another embodiment of the utility model, and the difference of present embodiment and last embodiment is: needle electrode 4 and needle electrode 7 all are positioned at the inboard of same pincers handle.
