Description

Examination electrical testing folder

(1), technical field: the utility model relates to a kind of test clip, particularly a kind of examination electrical testing folder.

(2); background technology: test clip is the common apparatus of electric energy detection industry; it mainly is used in the various field-checking instruments in the electric energy detection industry; the general regular meeting of detecting at the scene often is clipped in test clip on the exposed test point and detects; when reality is used; because the test point surface is oxidized through regular meeting; influencing test clip contacts with the reliable of test point; the problem that occurs loose contact sometimes; and at this moment only often be difficult to judge with naked eyes; will go wrong because of measured signal receives the undesired testing result that makes like this, how finding a kind of test clip of directly judging is a urgent problem with the method whether test point reliably contacts.

(3), utility model content:

The technical problems to be solved in the utility model is: at the prior art deficiency, provide a kind of have examination electric work energy, examination electrical testing folder easy to use.

The technical solution of the utility model:

A kind of examination electrical testing folder, contain, under conduct electricity clamp, coupling shaft and fastening spring, fastening spring is sleeved on the coupling shaft, connecting bushing is last, conduct electricity down in the axle bed of clamp, the fastening spring two ends in the opposite direction respectively the card be pressed in, conduct electricity the following of clamp down, on the upper surface, make, under conduct electricity the clamp retaining clip and hold contact, at the handle end plus-pressure it is opened, on, conduct electricity down the handle end outside surface of clamp or except that the clamping mouth on, following conductive clip external surface is provided with insulation sleeve, end at the handle end of last conduction clamp is electrically connected with current-limiting resistance successively, neon tube, the hand touched electrode, current-limiting resistance, neon tube is positioned at insulation sleeve, the part of hand touched electrode is sleeved in the insulation sleeve, another part exposes outside insulation sleeve, and position corresponding with neon tube on insulation sleeve has window.

In insulation sleeve, also be electrically connected with power spring between neon tube and the hand touched electrode.

It is very cylindrical that hand gets an electric shock, the internal thread of the external thread of hand touched electrode by its outside surface and insulation sleeve inwall cooperate and insulation sleeve links together; Saturating window place is equipped with clear glass or transparent plastic.

The handle end that conducts electricity down in the clamp is electrically connected with lead or conductive jack seat.

Jack on the conductive jack seat is a standard jacks; The clamping mouth is a profile of tooth clamping mouth; The profile of current-limiting resistance is cylindrical; The material of insulation sleeve is plastics.

The beneficial effects of the utility model:

1, the utility model is electrically connected with current-limiting resistance, neon tube, hand touched electrode successively in the end of the handle end of last conduction clamp, like this, when not judging directly whether test clip and test point contact when good, available hand contact hand touched electrode, see whether neon tube is shinny, as shinny test clip as can be known charged (test clip contacts well with test point),, very easy to use as not shinny test clip as can be known not charged (test clip and test point loose contact).

2, handle end or the upper and lower conductive clip external surface except that the clamping mouth of going up conduction clamp and following conduction clamp of the present utility model is provided with insulation sleeve, uses safe and reliable; Conduct electricity handle end employing and the mode that lead or conductive jack seat are electrically connected in the clamp down, use flexible and changeable.
