Abstract
The utility model relates to an improved test pencil plug which is mainly characterized in that the bare metal contact bar of the existing test pencil plug is sheathed with an insulated protective sheath; the middle end of the contact bar is sheathed with a spring to cause the insulated protective sheath to abut on the spring, and the insulated protective sheath can be freely expanded and contracted in the casing cavity body along the contact bar. In normal times, the contact bar can be fully sheathed by the insulated protective sheath. During measurement, the insulated protective sheath is pushed into the casing cavity body via a socket along the contact bar after the contact bar is inserted in the jack of the instrument. An operator can not contact the charged contact bar for avoiding the electric shock and ensuring the personal safety. The utility model can be used for connecting with various electric measuring instruments for measurement.
Description
The utility model relates to a kind of modified test pen plug, is used to connect all kinds of electrical measurement instruments and measures, and can guarantee operator's personal safety.
Existing test pen plug has an exposed Metal Contact bar, and the operator touches charged contact lever and will get an electric shock during use, and personal safety is difficult to be protected.
The purpose of this utility model is exactly in order to overcome above-mentioned shortcoming, and a kind of test pen plug that can avoid the operator to get an electric shock when measuring is provided.
The purpose of this utility model is achieved in that the plastic protective sleeve that puts an insulation on the exposed Metal Contact bar of existing test pen plug; overlap upper spring again; make that this protective sleeve can be capable of expansion and contraction along the Metal Contact bar in the plug body cavity; it entangles the Metal Contact bar fully at ordinary times; during use; after the Metal Contact bar of plug inserts the instrument jack; the ambroin protective sleeve is just pushed in the plug body cavity along the Metal Contact bar by socket; the operator measures with test pen; pull the plug out of the socket after finishing using; the ambroin protective sleeve just skids off along the Metal Contact bar in the plug body cavity, and entangles the Metal Contact bar.Like this, the operator just can not touch charged contact lever in whole test process, thereby has avoided electric shock, has guaranteed operator's personal safety.
Below in conjunction with accompanying drawing the utility model one embodiment is elaborated:
Fig. 1 is a structure cut-open view of the present utility model.
As seen from the figure, the utility model is made up of contact lever 1, insulation protective jacket 2, spring 3, joint 4 and shell 5.At first making diameter with brass wire is 2 millimeters; length is 35 millimeters contact lever 1; putting a diameter in its lower end then is 3.8 millimeters; length is the insulation protective jacket 2 that 14 millimeters ABS plastic is made; again therein end to put a diameter be the spring 3 that 0.2 millimeter carbon spring steel wires is done; and diameter of (taper) periphery riveted joint in the top is 4 millimeters; length is 11 millimeters joint 4; the lead 6 that will link to each other with test pen again inserts joint 4; make the awl end of contact lever 1 insert the multiply copper in-core of lead 6; joint 4 and lead 6 are riveted; put ABS plastic shell 5 at last, just constituted the utility model.
Owing to the utlity model has insulation protective jacket, after plug was connected instrument during measurement, the operator can not touch charged contact lever, thereby has avoided electric shock, has guaranteed operator's personal safety, just more can embody its security when measuring electric weight under condition of high voltage.
Claims (1)
