Abstract
The utility model provides a secure on-off pen which comprises a large pen body and a small pen body, wherein the heads of the large pen body and the small pen body are respectively provided with a contact pin, the tail ends of the large pen body and the small pen body are connected through a power wire, the large pen body is provided with a PCB (Printed circuit board) and button batteries, and the PCB is provided with an LED (light-emitting diode) indication light. The secure on-off pen is simple in structure, easy to carry, low in cost, safe and reliable to use, and can obtain judgment results quickly.
Description
Technical field
The utility model relates to circuit on-off testing tool field, is specifically related to a kind of safe break-make pen for detection of circuit on-off.
Background technology
At present, to the maintenance instrument commonly used of consumer break-make fault, be multimeter or special detector, use the deficiency of multimeter or special detector to be: complex structure, production cost is high, use inconvenient, if with multimeter during as testing tool, head does not stop to rock back and forth between cable and multimeter, slightly there are carelessness or the shake will all that has been achieved is spoiled, as tested with special detector, because operating voltage is very high very dangerous, and speed is slow, workload is large, and price is high, carries inconvenience.And at many working environments more severe occasion, due to the detecting instrument of multimeter one class, volume is large, weight is large, is difficult for carrying, described workman adopts some informal means to be overhauled breaking down often, so usually can cause adverse consequences.
Summary of the invention
Technical problem to be solved in the utility model is to provide safe break-make pen, simple in structure, easy to carry, with low cost, uses safety, reliable, can draw fast the safe break-make pen of result of determination.
For solving above-mentioned existing technical matters, the utility model adopts following scheme: safe break-make pen, comprise a large sum of body and little body, described a large sum of body and little body head are respectively equipped with contact pilotage, described a large sum of body is connected by power lead with little body afterbody, be provided with pcb board and button cell in described a large sum of body, described pcb board is provided with the LED display lamp, and described LED display lamp is provided with transparency window outward.Be provided with long spring in described little body, described little body afterbody is plugged with the tail plug, and described long spring is fixed in little body by the tail plug.
As preferably, in described a large sum of body, between pcb board and contact pilotage, be provided with short spring.There is buffer action, play better protective effect.
As preferably, described a large sum of body and little body both sides are respectively equipped with a large sum of flexible glue and little flexible glue.Make one-piece construction rounding more, conveniently hold.
As preferably, on the contact pilotage of described a large sum of body and little body head, overlap the cap for brush is arranged respectively.The protection contact pilotage is dustproof.
As preferably, on described a large sum of body tail, overlap the tail cap is arranged.A protection tail.
Beneficial effect:
The utility model adopts technique scheme that safe break-make pen is provided, simple in structure, easy to carry, with low cost, uses safety, reliable.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is explosive view of the present utility model.
Embodiment
As shown in Figure 1-2, safe break-make pen, comprise a large sum of body 1 and little body 2, described a large sum of body 1 and little body 2 heads are respectively equipped with contact pilotage 3, described a large sum of body 1 is connected by power lead 4 with little body 2 afterbodys, be provided with pcb board 5 and button cell 6 in described a large sum of body 1, described pcb board 5 is provided with LED display lamp 6, the outer transparency window 14 that is provided with of described LED display lamp 6.Be provided with long spring 7 in described little body 2, described little body 2 afterbodys are plugged with tail plug 8, and described long spring 7 is fixed in little body 2 by tail plug 8.Be provided with short spring 9 between the interior pcb board 5 of described a large sum of body 1 and contact pilotage 3.Described a large sum of body 1 and little body 2 both sides are respectively equipped with a large sum of flexible glue 10 and little flexible glue 11.Overlap the cap for brush 12 is arranged respectively on the contact pilotage 3 of described a large sum of body 1 and little body 2 heads.On 1 tail of described a large sum of body, cover has tail cap 13.
During real work, when the line short of test, a large sum of body 1 is inserted in test line, the electricity of button cell 6 forms and encircles with little body 2 by test line, can make LED display lamp 6 luminous, illustrates that this circuit has short-circuit conditions.
Specific embodiment described herein is only to the explanation for example of the utility model spirit, the utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
