Abstract
The utility model relates to a synergism cylinder for the neon tube display of a test pencil, which belongs to the class of test tools of an electrician. The utility model is characterized in that a synergism cylinder 1 of the utility model is a cylindrical cylinder which is arranged in the transparent observation window of a test pencil; the external side of the cylindrical cylinder is provided with a transparent observation hole 2; the inner wall of the synergism cylinder 1 of the utility model is polished or is coated with a substance layer which has favorable performance of reflection of light; the outer wall is coated with a coating layer with great contrast with the color of the light generated by a neon tube. The original test pencil which is additionally provided with the synergism cylinder of the utility model has easy use and safety, and can not cause erroneous judge.
Description
The utility model belongs to electrical measuring instrument class.
At present commercially available and produce in widely used test pencil, great majority are by the metal nib, high value resistor, luminous neon tube, spring and plastic casing are formed.This test pencil is simple in structure, and is easy to maintenance, cheap, but its weak point is in luminous environment is arranged, and especially under the high light environment, shows signal is extremely faint, causes error in judgement during observation easily, thereby accidents caused.
The purpose of this utility model is to provide a kind of neon tube that is arranged at specially on the test pencil inner casing neon tube outer wall to show the synergy tube, it is suitable for all is the test pencil of shows signal with the neon tube, enable in luminous environment is arranged, especially in the high light environment, strengthen shows signal.
The said synergy tube of the utility model is the garden column casing that has the printing opacity observation port that is arranged at the interior neon tube periphery of test pencil transparent sight hole.
Fig. 1 is the utility model and neon tube assembling synoptic diagram.Fig. 2 is the stretch-out view of embodiment 1 of the present utility model and embodiment 2.
In conjunction with the accompanying drawings the utility model is further described below by embodiment.
This synergy tube 1 is a garden column casing shape, and it is enclosed within the neon tube outer wall, can bond the physics flexible fastening of also available synergy tube material.Draw materials with light, thin, the soft metal sheet get final product, is good with aluminium especially, also can be with material such as plastics or paperys, inwall polishing or be coated with the reflective material layer, outer wall is coated with the coating with the photochromic contrast maximum of being sent with neon tube, first elects black coating.When making of conductive metal, this synergy tube length degree should be less than the length between the contact of neon tube both sides.Transparent observation port 2 on the tube is slots (seeing Fig. 2 embodiment) of alternate 120 ° of distributions on this garden tube week, also a spiral-shaped orifices (seeing Fig. 3 embodiment 2).
Synergy principle of the present utility model is: common test pencil shell and neon tube are transparent plastic and glass, after adding the synergy tube, provide full black background for signal shows, and blocked the parasitic light that has absorbed from beyond the observed ray, signal contrast is strengthened greatly; Because inner polishing makes the light signal of dispersion shape be reflected concentrated output, and signal is strengthened.
After former test pencil adds this synergy tube, esy to use, safe and reliable, economical handy, can not cause error in judgement, and because material source is extensive, technology is simple, and is cheap, be suitable for large-scale production and need not change original technical design and equipment, more also extremely convenient owing to existing finished product is installed additional, manufacturer takes like a shot, and promotion prospect is very wide.
Claims (4)
1, the test pencil neon tube shows the synergy tube, it is characterized in that this synergy tube 1 is to be arranged at the cylindrical drum that the interior outside of test pencil transparent sight hole has printing opacity observation port 2, this inwall polishing or be coated with reflective function material layer preferably, the photochromic contrast bigger coating of outer wall for being sent with neon tube.
2, synergy tube according to claim 1 is characterized in that its length is slightly less than the length between the metal contact of neon tube both sides when conductive metal material is made this synergy tube.
3, synergy tube according to claim 1 is characterized in that the printing opacity observation fenestra 2 on this synergy tube is slots of alternate 120 ° of distributions on this circumference.
4,, it is characterized in that the printing opacity observation fenestra 2 on this synergy tube also can be spiral-shaped orifices according to claim 1,3 described synergy tubes.
