Description
Technical field
The utility model relates to the replaceable contact electroscope of a kind of piercing low pressure.
Background technology
Contact low pressure electroscope is that whether charged work about electric power personnel on site to detect in electrical equipment of low voltage conventional testing tool.Low pressure electroscope divides contact, induction type two type.Induction type low pressure electroscope, because test result is inaccurate sometimes, is inhibited in electric power overhaul working-yard and applies.Electric power safety code (distribution section) 4.3.1 article regulation: electrical verification need use contact electroscope or the electroscope of relevant voltage grade.
Because the termination of contact low pressure electroscope mostly is yi word pattern, be limited to the enforcement of low-voltage network all insulation measure, contact electroscope rig-site utilization is limited, thus often appear as realize contact survey electricity must first dial the situation of cutting conductor insulation sheath.
The patent No. is that CN201120520581 discloses a kind of electroscope, comprise neon tube, resistance, the hand touched electrode of insulation crust, test contact and described insulation crust inside, also comprise lighting device, it is inner that described lighting device is positioned at described insulation crust, described lighting device comprises independent current source and switch, and described test contact is metal acicular texture.But the test contact due to this patent is set to metal acicular texture, come with some shortcomings, when this patent electroscope uses, due to contact be acicular texture prick electric wire wire skin with regard to time must be cautious, because once careless, just in case pierce through 2 lines simultaneously, low-voltage short-circuiting fault will be caused, burn wire, burn Novel electroprobe, even end user is also burnt; After thrusting wire skin, also have a long joint and stay outside wire skin, at this moment sewing-needle has been charged simultaneously.Encounter because of carelessness will get an electric shock as test person, because it has also filled individual torch in electroprobe front end, so the finger of test person can be accustomed to go to test pencil front end touch, if test person finger encountered charged spicule because of carelessness, probably formed one act of tragedy; Pin will leave more relatively large wound at bundle after wire skin.
Utility model content
It is simple that technical problem to be solved in the utility model is to provide a kind of structure, easy to use, the replaceable contact electroscope of piercing low pressure of replaceable contact.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: the replaceable contact electroscope of a kind of piercing low pressure, comprise transparent plastic shell and test contact, described transparent plastic shell and described test contact removably connect, described transparent plastic shell inside is provided with the first Metallic rod successively, resistance bolck, neon tube and spring, described transparent plastic shell end is connected with crown cap, described test contact comprises the second Metallic rod and plastics fixture block, described plastics fixture block is cast around described second Metallic rod and is formed, described second Metallic rod top is provided with the puncturing head of scarf.
Further, described transparent plastic shell bottom is provided with dismountable card cap, and described test contact is fixed on described transparent plastic shell by described card cap.
Further, described transparent plastic shell is provided with the groove suitable with described plastics fixture block, described bottom portion of groove is provided with the first strong magnets, described plastics fixture block lower end is provided with the second strong magnets, and described test contact passes through the first strong magnets magnetic attracting of the second strong magnets and described transparent plastic shell.
Further, described second Metallic rod diameter is 0.4mm, and the length of described puncturing head is 3mm.
The beneficial effect adopting technique scheme to produce is: contact of the present utility model is set to removable contact, contact top is provided with the puncturing head of scarf, puncturing head was when using the tip caused blunt for a long time at that time, puncturing head can be changed easily, thus maintain the sharp of puncture; Because puncturing head is set to 3mm, this length can ensure that the line skin of primary cable is punctured, pierce through the length reserved outside rear wire and be about 1mm, thus ensure that tester points the space touched, completely avoid tester touch electroprobe contact and cause get an electric shock possibility; Because puncturing head is very thin, very small of the wire insulation institute mark after puncture, achieves microscratch puncture, is requiring relatively low place for wire insulation, no longer can carry out insulation reparation.
