Abstract

Disclosed is a testing display, which comprises a light-emitted diode (8), a base (2), a contact group (1) and a button (3). The light-emitted diode (8) is arranged inside the button (3); the button (3) and the contact group (1) are arranged inside the base (2). The testing display is characterized in that the button (3) is connected with a slide block (10) arranged inside the button (3); a contact piece (12) is connected on the slide block (10); the contact group (1) is composed of a fixing base (9), a contacting blade (6) and a contacting foot (7); the contacting blade (6) and the contacting foot (7) are fixed inside the fixing base (9); the two ends of the contacting blade (6) are extended out of the fixing base (9), with one end facing the contact piece (12) and the other used as the measuring end of the whole testing display; a spring (11) is arranged between the slide block (10) and the fixing base (9). The testing display has the advantages of simple structure, and flexible and convenient operation.

Description

Detect display

Technical field

The utility model relates to a kind of radio component, the electric elements that use on especially a kind of communication radio station, specifically a kind of detection display.

Background technology

At present, make a kind of detection display that display uses in radio station apparatus, its technical requirement is:

1. working temperature :-45 ℃～+ 85 ℃;

2. relative humidity: 95% ± 2% temperature is 40 ℃;

3. vibration: shaking is 10-55Hz, acceleration 1-4g frequently;

4. button is on position power＜1kg;

5. contact resistance≤0.05 Ω during switch connection;

6. volume: 48 * φ 12 (mm).

Because its requirements is comparatively special, and according to the knowledge of the applicant, on the market still incapability to satisfy the detection display of above-mentioned requirements available.

Summary of the invention

The purpose of this utility model is a kind of detection display of design, to satisfy the needs of telecommunication equipment.

The technical solution of the utility model is:

A kind of detection display, comprise light emitting diode 8, pedestal 2, contact sets 1 and button 3, light emitting diode 8 is installed in the button 3, button 3 and contact sets 1 are installed in the pedestal 2, slide block 10 in it is characterized in that described button 3 and being installed in pedestal 3 equally links to each other, be connected with contact chip 12 on the slide block 10, contact sets 1 is by holder 9, contact cutter 6, contact feet 7 is formed, contact cutter 6, contact feet 7 is fixed in the holder 9, two ends of contact cutter 6 all stretch out outside the holder 9, one end is relative with contact chip 12, and the other end is equipped with spring 11 as the measuring junction of whole detection display between slide block 10 and holder 9.

Near on the end of button 3 nut 4 and elastic washer 5 are installed at pedestal 1.

The beneficial effects of the utility model:

1) simple in structure, volume is little, utilizes the slip form to make the light emitting diode through and off, has sensitive advantage reliably.

2) contact resistance is little, contact resistance of the present utility model≤0.05 Ω.

3) light emitting diode is connected thrust and is not more than 1kg, and is flexible to operation.

4) volume is little, and whole volume can be controlled in the φ 12 * 48 (mm).
