Abstract

The utility model provides an electric test probe, comprising a probe head, a probe tube and a spring arranged in the probe tube; the utility model is characterized in that the surface of the spring is coated by an insulating layer, or insulation pieces are arranged between both ends of the spring, that is, between the probe head and the spring and between the spring and the probe tube. The utility model has the advantages of simple structure and convenient use; because the surface of the spring is coated by the insulating layer, and the insulation pieces are arranged between both ends of the spring, the spring is completely insulated, which ensures that the spring of the electric test probe can always keep a good working state even under the condition of the heavy current, thereby the utility model is reliable in performance.

Description

The Electronic Testing probe

Technical field

The utility model belongs to the electronic connector technical field, is specifically related to a kind of architecture advances of Electronic Testing probe of suitable high-current test applications.

Background technology

At hand held communication product, mobile phone, computer, and the research and development of products such as instrument and meter, semiconductor, produce, the Electronic Testing probe is a kind of connector commonly used, in order to keep the excellent contact state, the needle tubing of Electronic Testing probe is built-in with spring, probe closely contacts with tested pilot on the printed-wiring board (PWB) by means of the elastic force of spring.But, might blow cisco unity malfunction because of resistance heating causes spring in big current applications.

The utility model content

The purpose of this utility model provides a kind of simple in structure, dependable performance, easy to use, is fit to the Electronic Testing probe of high-current test applications.

For achieving the above object, the technical scheme that adopts is: a kind of Electronic Testing probe, comprise probe, needle tubing and place the interior spring of described needle tubing, it is characterized in that: described spring surface-coated has insulation course, or, promptly be equipped with insulating part between probe and the spring and between spring and the needle tubing at the two ends of described spring.

The beneficial effects of the utility model are: simple in structure, easy to use, because described spring surface-coated has insulation course, both ends of the spring is equipped with insulating element, so spring is in state of insulation fully, the spring that makes the Electronic Testing probe is under big current conditions, also can be in good working order, dependable performance all the time.

Description of drawings

Below in conjunction with drawings and Examples, the utility model is described in further detail.

Fig. 1 is single probe the utility model structural representation;

Fig. 2 is single another structural representation of probe the utility model;

Fig. 3 is two probe the utility model structural representations.

Among the figure, 1,1 '-probe; The 2-needle tubing; 3,3 '-insulating part; The 4-spring.

Embodiment

Fig. 1 is single probe the utility model structural representation, and from Fig. 1 as seen, the Electronic Testing probe is built-in with the spring 4 that surface-coated has insulation course at needle tubing 2, and probe 1 joins successively with spring 4, needle tubing 2; Fig. 2 is single another structural representation of probe the utility model, for fear of applying imperfect at the two ends of described spring 4 insulation course, guarantee the insulation fully of spring 4, between probe 1 and spring 4, be equipped with insulating part 3, be equipped with between spring 4 and the needle tubing 2 insulating part 3 '.Fig. 3 is two probe the utility model structural representations, be shown in needle tubing 2 and be built-in with the spring 4 that surface-coated has insulation course, spring 4 two ends respectively by insulating part 3 and 3 ' with probe 1 and 1 ' join.

Should be appreciated that spirit of the present utility model is that spring is insulated fully, electric current does not pass through from spring.So in this conceptual framework, no matter probe 1, needle tubing 2 and insulating part 3 which kind of shape: circle, triangle or fluted body, all within the scope of the utility model protection.

Claims

1. an Electronic Testing probe comprises probe (1), needle tubing (2) and places the interior spring (4) of described needle tubing (2), and it is characterized in that: described spring (4) surface-coated has insulation course.

2. according to the described a kind of Electronic Testing probe of claim 1, it is characterized in that: the two ends of described spring (4) are equipped with insulating part (3,3 ').
