Abstract
Disclosed is test pencil which is provided with a metal test contact (1) and an insulated handle (5). A hand touch electrode (6) is arranged on the handle, and the hand touch electrode is connected with the front test contact through a luminous tube installed in the handle and a current-limiting resistance. The test pencil is characterized in that the front end of the handle is provided with a hand protection disc (3) which encircles the handle and protrudes radially. The hand protection disc arranged at the front end of the insulated handle of the utility model can effectively ward off the finger of the tester, prevent the finger from sliding and touching the test contact which has electricity; thereby, the safety of the usage is increased.
Description
Technical field
The utility model belongs to a kind of electrical measurement, is specifically related to a kind of test pencil.
Background technology
Test pencil mainly is provided with the metallic test contact (1) of elongated rod shape, insulated handle (5), handle is provided with hand touched electrode (6), the hand touched electrode is electrically connected with the test contact of front portion by neon tube, the current-limiting resistance that is contained in the handle, during use, the tester holds handle, and finger is contacted on the hand touched electrode, make test contact contact detection position, whether whether shinny judgement detection position is charged can to pass through neon tube.In testing process, common people's custom is with two banjo splints handle of stopping, and thumb is pressed on the hand touched electrode at rear portion, makes test contact contact detection position, if two fingers of tong handle are run into test contact to front slide accidentally, electrification in promptly can taking place.
Summary of the invention
The finger that the technical problems to be solved in the utility model provides a kind of tester's of preventing handle slides into anterior test contact, improves the test pencil of security.
The technical scheme that addresses the above problem is: the utility model is provided with metallic test contact (1), insulated handle (5), handle is provided with hand touched electrode (6), the hand touched electrode is electrically connected with the test contact of front portion by luminotron, the current-limiting resistance that is contained in the handle, and it is characterized in that: described handle front end is provided with around handle to the hand guard (3) that radially protrudes all around.
Further scheme is: the diameter of described hand guard maximum with the diameter difference at handle and the crosslinked place of hand guard greater than 10mm.
The utility model can advancing sliply not contact charged test contact at the finger that the hand guard of insulated handle front end setting can effectively block the tester, thereby has improved the security of using.

Specific embodiments
This example is provided with elongated rod shape measuring head 1, and the measuring head rear portion is an insulated handle 5, and hand touched electrode 6 is positioned at handle rear end, is electrically connected with the measuring head 1 of front portion by current-limiting resistance, the neon tube that is contained in the handle.
In order more effectively to play the effect that stops that finger is advancing slip, the diameter difference at the maximum gauge of hand guard and handle place 51 crosslinked with it should be greater than 10mm, and this routine diameter difference is 12mm.
Be with insulating sleeve 2 on the elongated rod shape measuring head 1 rear portion body of rod, with its security performance of further raising.
This routine handle 5 and hand guard 3 are the integrative-structures that form with the insulating material cast.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is done any pro forma restriction; every foundation technical spirit of the present utility model all still belongs to the protection domain of technical solutions of the utility model to any simple modification, equivalent variations and modification that above embodiment did.
Claims (3)
1, a kind of test pencil, be provided with metallic test contact (1), insulated handle (5), handle is provided with hand touched electrode (6), the hand touched electrode is electrically connected with the test contact of front portion by luminotron, the current-limiting resistance that is contained in the handle, and it is characterized in that: described handle front end is provided with around handle to the hand guard (3) that radially protrudes all around.
2, test pencil according to claim 1 is characterized in that: handle (5) front end is provided with around handle, center symmetrically to the described hand guard (3) that radially protrudes all around.
3, test pencil according to claim 1 and 2 is characterized in that: the diameter of described hand guard maximum with the diameter difference at handle place crosslinked (51) with it greater than 10mm.
