Embodiment 1

[0030] Embodiment one, such as Figure 1 to Figure 7 As shown, a new type of electric measuring pen includes a pen case 1, the upper end of the pen case 1 is provided with a hand-touch electrode 5, the lower end of the pen case 1 is provided with a conductive knife rod 2, and the pen case 1 is provided with a The neon bulb light emitting assembly 3 and the conductive spring 6, the inner end of the conductive spring 6 abuts against one end of the neon bulb light emitting assembly 3, the outer end of the conductive spring 6 abuts on the hand contact electrode 5, the neon bulb light emitting assembly The other end of 3 abuts against the conductive knife bar 2, and the hand touch electrode 5 is electrically connected with the neon bulb light-emitting assembly 3 through the conductive spring 6.

[0031] The outer surface of the pen case 1 is provided with a light source refraction structure 41 corresponding to the position of the neon bulb of the neon bulb light-emitting assembly 3...

Embodiment 2

[0048] Embodiment 2. Embodiment 2 is similar to Embodiment 1. The only difference is that: the light source refraction structure 41 is provided on the outer surface of the pen case 1, and the light source refraction structure 41 is integrated with the pen case 1. Molded, the pen case 1 is made of transparent material. The outer surface of the pen case 1 is provided with a plurality of light source refracting structures 41 at intervals along its circumferential direction.

Abstract

The invention relates to a novel test pencil comprising a pencil shell. The upper end of the pencil shell is provided with a hand contact electrode. The lower end of the pencil shell is provided with a conductive cutter bar. The pencil shell is internally provided with a neon bulb light-emitting component and a conductive spring. The position, which is corresponding to the neon bulb of the neon bulb light-emitting component, of the external surface of the pencil shell is provided with a light source refraction structure. The light source refraction structure is transparent and convex. The external surface of the light source refraction structure is provided with multiple light source refraction surfaces. The inclined angle between the two adjacent light source refraction surfaces is an obtuse angle. The position, which is corresponding to the neon bulb, of the external surface of the pencil shell is provided with the transparent and convex light source refraction structure. The multiple light source refraction surfaces on the light source refraction structure refract the light of the neon bulb to form multiple light-emitting sources on the light source refraction structure so that the brightness of the neon bulb is intensified to multiple times of the original brightness, the visible area and the brightness of the neon bulb light source can be enhanced, the user is enabled to see more clearly, the detection efficiency is higher and detection is faster.

Description

technical field [0001] The invention relates to the technical field of circuit maintenance tools, in particular to a new electric measuring pen. Background technique [0002] The electric test pen is a very commonly used electrical tool, which is used to test whether the electric wire is charged. After the electric test pen is in contact with a charged object, the inner neon bubble lights up, indicating that the object has a voltage of more than 80V. However, the existing electric measuring pens have the following deficiencies: (1) Due to the extremely limited brightness of the neon bulb, in a relatively bright environment, the interference received is very serious, which may cause the user to be unable to see whether the neon bulb is emitting light, thereby As a result, the user cannot determine whether the object is charged, and it is easy for the user to get an electric shock, which poses a safety hazard. Contents of the invention [0003] The object of the present inv...
