Abstract
The utility model relates to an electric potential, voltage type multi-purpose test pencil, mainly composed of an electrode, a resistor, a conducting strip, an insulated wire, an insulated outer shell, an electric potential displayer, a pencil clip, a voltage displayer, a spring, a conducting wire combination connection head, and a voltage detection rod. The electrode, two resistors, the electric potential displayer and a human body earthing point are jointed in series in sequence. One end of the voltage displayer is connected with the connection points of the two resistors. The other end of the voltage displayer is connected with the voltage detection rod. The utility model is characterized in that not only the test pencil can measure electric potential, but also the test pencil can measure voltage. The utility model can distinguish whether the voltage with 220V and 380V exists or not. The utility model can detect and judge some faults on circuits.
Description
The utility model relates to the new varieties of test pencil.
Existing test pencil can only detect current potential, can not detect voltage, so can not conclude some fault on the circuit, purposes is single.
The purpose of this utility model is to provide a kind of can survey current potential, can survey voltage, the electric potential type of voltage again and use test pencil more.
With reference to accompanying drawing 1-2, the utility model is to adopt potential display (7) one termination human body grounding points (9), the other end is connected with resistance (2,5) and electrode (1), voltage display (13) one terminating resistors (2,5) tie point, the mode of another termination voltage detecting rod (22) achieves the goal.
Characteristics of the present utility model: the one, this test pencil can be surveyed current potential, can survey voltage again, can differentiate 220V, whether 380V voltage exists, and can detect some fault on the decision circuitry,, work high above the ground, can replace universal meter to use in the open air, carries, easy to use; The 2nd, simple and compact for structure, cheap.
Below in conjunction with accompanying drawing embodiment is described:
Fig. 1 is this test pencil longitudinal section.
Fig. 2 is this test pencil circuit diagram.
With reference to Fig. 1-2, this test pencil is by electrode (1), resistance (2,5), conducting strip (3,10,12), insulated conductor (4,21), insulation crust (6,17,20), potential display (7), current potential see-through window (8), pen clip (the double as human body grounding utmost point) (9), insulating trip (11), voltage display (13), voltage see-through window (14), becket (15), spring (16), lead combination sub (18,19) and voltage detecting rod (22) form, case head (20), neck (17), body portion (6), pen clip (9) and lower end electrode (1) are formed outer likeness in form ball pen shape, join from the bottom to top in the shell resistance (2) is housed, conducting strip (3), resistance (5), potential display (7), conducting strip (10), insulating trip (11), conducting strip (12), voltage display (13), spring (16), lead combination sub (18,19) and lead (21), another termination voltage detecting rod (22) of lead (21), joint (18) is like button-headed screw, a middle screw in addition, joint (19) has the ring flange double-screw bolt for the middle part, upper end welding lead (21), the top cylinder is in case head (20) mesopore, the ring flange screw thread is connected with case head (20) bottom screw, shell neck (17) upper end hole packs into joint (19) bottom double-screw bolt, connect with joint (18), becket (15) is placed on outer body portion (6) shoulder, shell neck and body portion (17,6) with being threaded, body portion (6) peace current potential, voltage display (7,13) locate respectively to have the see-through window (8 of usefulness transparent material sealing, 14), pen clip (9) upper end engages with becket (15), sheet metal (3) and sheet metal (12), sheet metal (10) uses insulated wire (4) to be connected respectively with becket (15), its circuit connecting mode: electrode (1), resistance (2), resistance (5), potential display (7), human body grounding point (9) is connected successively, voltage display (13) one terminating resistors (2) and resistance (5) tie point, another termination voltage detecting rod (22).
