Abstract
The utility model relates to a multifunction needle-shaped contact head test pencil which is composed of a main pencil and an auxiliary pencil. Metal rods (2) are arranged in insulating outer shells (3) (17) of the main pencil (4) and the auxiliary pencil (16). The front end of the metal rod (2) is provided with a needle-shaped contact head (1). A resistor (6), a neon tube (7) and a spring (8) are arranged in a cavity at the back end of the main pencil. A metal plug hole (11) is arranged in a back cover (10) of the test pencil. The back end of the metal rod in the auxiliary pencil is connected with a metal conducting wire (13), wherein, the other end of which is inserted into the metal plug hole (11) by a plug (12). The utility model can singly use the main pencil to test a live wire. The main pencil and the auxiliary pencil can be connected together to test a live wire and a zero wire. When the utility model is used for a test, the needle-shaped contact head pierces an insulating layer to contact a wire core, which is rapid and convenient. The utility model is suitable for testing various wires.
Description
The utility model relates to test pencil, particularly a kind of multi-functional aciculiform contact test pencil.
Test pencil has following weak point in the prior art: 1, when the non-exposed lead of test, need untie the adhesive plaster of joint, perhaps the stripping of insulatin layer; 2, when the test live wire, because of the resistance factor of human body, the electroprobe starter is not obvious; 3, running into zero line when obstructed, common electroprobe is searched difficulty, causes unnecessary trouble and waste time in repair circuit.
The purpose of this utility model is: a kind of multi-functional aciculiform contact test pencil is provided, it both can use the chief editor to test live wire separately, again can be major and minor pen couple together the test zero line, when the live wire of measurement circuit and zero line, contact with core with sharp aciculiform contact insulation-piercing layer, both do not untie the adhesive plaster of joint, do not wanted the stripping of insulatin layer again, reached purpose quickly and easily.
Formation of the present utility model: constitute by chief editor and secondary pen, chief editor's (4) insulation crust (3) center is metal bar (2), the front end of metal bar (2) is the aciculiform contact (1) that stretches out insulation crust (3), the rear end of metal bar (2) connects resistance (6) and neon tube (7), and neon tube (7) is connected with the middle metal jack (11) of electroprobe bonnet (10) by spring (8);
Insulation crust (17) center of secondary pen (16) is metal bar (2), the front end of metal bar (2) is the aciculiform contact (1) that stretches out insulation crust (17), the rear end of metal bar (2) is connected with an end of plain conductor (13), the other end of plain conductor is installed plug (12), is inserted in the metal jack (11) in chief editor (4) the electroprobe bonnet (10).Insulation crust (3) front end is conical, and the cavity of installation resistance (6), neon tube (7) and spring (8) is arranged in the rear end, and insulation crust (3) is connected by screw thread (9) with electroprobe bonnet (10), goes up the anti-skidding retaining (5) of oriented outer lug at insulation crust (3) (17).Insulation crust (17) on the secondary pen (16) and a secondary bonnet (14) are interconnected by screw thread (9), and a secondary cavity (15) is arranged in a pair bonnet of metal bar (2) and plain conductor (13) junction, and insulation crust (17) front end of secondary pen (16) is conical.Chief editor (4) insulation crust is the transparent body, perhaps opens the window of observing the neon tube starter at neon tube (7) position.
Compared with the prior art, the utility model is when searching live wire, can pull up the plug of auxiliary connection pen from the chief editor, the metal jack that catches and touch chief editor's bonnet, can arbitrarily test on by line inspection road, with sharp aciculiform contact, the insulation-piercing layer contacts with core during test, both do not untie the adhesive plaster of joint, do not wanted the stripping of insulatin layer again.
When searching zero line and whether switch on, in the metal jack on the plug insertion chief editor bonnet that connects with secondary pen, just can search test, on live wire, contact chief editor's aciculiform contact is perverse during test with core, again the aciculiform contact of secondary pen thorn is contacted with core on zero line, can find zero line rapidly and whether switch on, bring great convenience for the maintainability test circuit, both save the time, improved work efficiency again.
Accompanying drawing is the utility model structural representation.
Embodiment of the present utility model: as shown in drawings, in chief editor's (4) insulation crust (3) front end is metal bar (2), the rear end is a cavity, resistance (6) is installed in cavity, neon tube (7) and spring (8), rear end at insulation crust (3) is connected with electroprobe bonnet (10) by screw thread (9), the anti-skidding retaining (5) of oriented outer lug on the cylindrical of insulation crust (3) (17), front end at metal bar (2) is the aciculiform contact (1) that fuses with metal bar, at the center of electroprobe bonnet (10) metal jack (11) is arranged, chief editor (4) can be made by transparent plastic, perhaps open a transparent window, in order to observe whether starter of neon tube at the neon tube place.
Secondary pen (16) outside is insulation crust (17), the center is metal bar (2), the front end of metal bar is the aciculiform contact (1) that stretches out insulation crust (17), the rear end of insulation crust (17) is connected with a secondary bonnet (14) by screw thread (9), a secondary cavity (15) is arranged in a secondary bonnet (14), one of plain conductor in cavity (13) is connected with metal bar (2) rear end in the secondary pen, and the other end of plain conductor (13) is connected with chief editor (4) by plug (12) insertion metal jack (11) is interior.
When searching live wire, can pull up plug (12) from chief editor (4), catch and touch metal jack (11) on chief editor's bonnet (10), can on by line inspection road, arbitrarily test, during test sharp aciculiform contact (1) insulation-piercing layer is contacted with core, show lead energising as the neon tube starter, continue again to search as starter not.
When searching zero line and whether switch on, the plug (12) that connects with secondary pen (16) is inserted in the metal jack (11) of chief editor's bonnet (10), just can search test, during test chief editor's aciculiform contact (1) be stung on live wire, contact with core, again the aciculiform contact (1) of secondary pen is stung on zero line, with core contact, if chief editor's (4) neon tube (7) starter shows that live wire, zero line all switch on, as starter not, prove that a lead is obstructed.
