Abstract

The invention relates to a test pencil probe. A probe rod sleeve is sleeved outside a probe rod of which one end is provided with a probe needle; and one end of the probe rod sleeve is provided with aprobe hook, and the body of the probe hook is provided with a probe hole coaxial with the probe rod. The probe not only can be directly connected to an exposed part of a conductor, but also can be fixed on a wire covered with an insulating layer to penetrate the insulating layer to reach a conductor inside. The probe needle is retracted in a probe needle sleeve, and the probe rod can be connectedwith different test circuits as required, so the test pencil probe is convenient to carry and safe to use, and is suitable to be applied to multiple kinds of electrical circuit repair work.

Description

A kind of test pencil probe

[technical field]

The present invention relates to a kind of probe of test pencil.

[background technology]

The test pencil that present people use always will contact the just relevant electric weight of energy measurement with measured body.The probe of this class contact-type test pencil has tool-type and non-tool-type.The probe of tool-type mostly is crewdriver attachment; But not the probe of tool-type is exactly a Metallic rod.Their common shortcomings are exactly just can carry out electric quantity test after running into when electric wire that insulant covers or conductor are arranged, often needing to peel off insulant or dismounting.Though have in the prior art in knife bar type probe side the metal fine needle be installed, wear the test pencil probe that insulant carries out electric quantity test in order to bundle, but because the metal fine needle is fixed on knife bar type feeler lever side, both dangerous, limited environment for use again, to unfixed electric wire as helping also to be difficult to test without the another hand.

[summary of the invention]

The object of the present invention is to provide a kind of built-in feeler lever and probe of having, both can directly contact the conductor exposed part, can fix the lead and the bundle that are covered with insulation course again and wear the test pencil probe that insulation course touches inner conductor.

The present invention takes following measure to realize: the feeler lever outside that probe at one end is housed puts the feeler lever cover made from insulating material that an end has finger pin, be in out a hole coaxial at the finger pin hook with finger pin, this hole can make the probe that is contained on the feeler lever stretch out, and the V-type groove at the bottom of the finger pin can make the lead location and the centering of hooking.The spring that is placed between feeler lever and the feeler lever cover can make the feeler lever cover reset, and probe is contracted in when not working in the feeler lever cover.Need only hook the finger hook that feeler lever puts with finger during work the feeler lever cover is reclaimed to handle orientations, probe is just extended.

The present invention compares with prior art, except that connecting the exposed conductor of the direct contact of the electric display device of survey it is carried out the electric quantity test, it can also hook the lead that is covered with insulation course with the finger pin that feeler lever overlaps front end, lead can not be moved, and thrust with probe and to touch inner conductor in the insulation course and carry out electric quantity test.The conductor that insulation course is arranged for being fixed on other objects can stretch out probe from inspecting hole, directly thrust insulation course and touch inner conductor and carry out electric quantity test.Above-mentioned work all can be finished by a hand.When not working, feeler lever is enclosed within the effect of spring and automatically resets, and probe is packed in the feeler lever cover, avoids the people is caused injury.

Fig. 1 is vertical cut-away view of the present invention.

Fig. 2 is a kind of embodiment synoptic diagram of the present invention.

[embodiment]

As shown in Figure 1, one end of feeler lever 7 has Probe clip 2, probe 1 is housed on the Probe clip, feeler lever and probe outside are with the feeler lever cover 4 that an end has finger pin 3, be in an inspecting hole 5 coaxial with feeler lever at the finger pin hook, along the hook bottom horizontal corresponding with the feeler lever axis V-type groove 10 arranged in the hook body, an end side surface of feeler lever cover Wugou has the hook 9 of finger, between feeler lever and the feeler lever cover spring 8 is arranged, also have collar 6 on the feeler lever.

Among the embodiment 1 as shown in Figure 2, handle 14 is the common in the market multipurpose combined tool handle that survey electric work energy is arranged, and 11 is the knife bar seat, the different tool heads of can pegging graft on the knife bar seat, and 12 is set nut, 13 is neon bulb.Figure 2 shows that the feeler lever cover reclaims to handle orientations, the state when probe stretches out.One end of feeler lever needleless is injected in the knife bar seat, screw set nut, just can carry out electric quantity test.To exposed or be fixed on other objects when being covered with the conductor test of insulation course, only need one to hold handle, wherein a finger hooks and refers to that hook exerts oneself to handle orientations, the feeler lever cover is reclaimed, probe stretches out from inspecting hole, can directly contact conductor or insulation-piercing layer and make probe touch conductor to carry out electric quantity test.It is unguyed fixed and when being covered with the lead of insulation course to run into, earlier hook lead, make lead location and centering, hook the finger uncinate gyrus again and receive with finger pin, probe is stretched out in the feeler lever cover, and the wire insulation that hooks is pierced through the conductor that probe is touched in the insulation course test.

Embodiment 2, as handle as described in the embodiment 1, if the circuit of packing in handle and measuring and showing the low-voltage DC charge value then can become automobile driver and detect the automobile circuit situation, and the utility that in the household electrical appliance maintenance, detects various circuit.

Claims
