Description

The charactron of light leakage

Technical field

This utility model is related to electronic device, more particularly to a kind of charactron of light leakage.

Background technology

Charactron is a kind of display output element for display digit, the electric equipment for using in the family（As air-conditioning, Electromagnetic oven, electronic clock etc.）, the electric equipment for using in the factory（Such as data monitor, circuit tester etc.）.

At present, the production technology of conventional digital pipe is generally comprised the steps:

1) wear rivet by artificial or machine rivet through the pin bores on pcb board position;

2) pressure rivet, flattens the rivet on pcb board with semi-automatic rivet driver, forms contact pin;

3) die bond, is bundled in the luminescence chip needed on pcb board on pad relevant position by bonder;

4) routing, with automatic wire bonder carrying out line on luminescence chip and pcb board between the both positive and negative polarity of pad;

5) survey in, power consumption parameter tester carries out electric performance test;

6) mixed proportion of modulating epoxy resin, conventional ratio epoxy resin:Firming agent:Diffusant is 90:100:20;

7) tape, charactron reflection cap patch high temperature gummed tape, and 80 degree of preheatings, two hours in an oven, exclude reflection Aqueous vapor in lid;

8) encapsulating, is poured into the epoxy resin for modulating by glue pouring machine and goes out optical channel in the reflection cap for posting adhesive tape In, and evacuation;

9) assemble, the middle pcb board surveyed is assembled in the reflection cap for having filled glue;

10) high-temperature baking, is typically placed in high temperature roaster with 80 °C -- 100 °C of baking 6-8 hours;

11) survey eventually, power consumption parameter tester carries out photoelectric properties test.

And prior art, when rivet is worn, typically rivet can be passed a pcb board part, and this part for passing is referred to as For pin, and the presence of pin will certainly make pcb board be about the gap of contact pin grease head highness into depth with reflection hull shape, this , when charactron operationally, luminescent wafer on pcb board lights, but due to the presence in gap, can occur to dissipate in gap The phenomenon of light, the luminescence window due to reflecting " 8 " font for including on shell that separate luminous byte is constituted, now, works as number During code pipe display digit, corresponding luminescent characters festival-gathering lights, and due to the presence of astigmatism phenomenon caused by the presence in gap, can make Luminous reflective window does not have certain brightness to luminous byte yet, so as to cause the unclear phenomenon of numerical monitor.

Utility model content

The purpose of this utility model is to provide a kind of luminous tube of light leakage, can be tight with reflection shell with pcb board Laminating, prevents luminous tube from light leakage phenomena occur when luminous to play.

Above-mentioned purpose of the present utility model technical scheme is that：

The charactron of light leakage, including contact pin, pcb board and reflection shell, the contact pin press to be formed through the pcb board Pin, the pcb board are fixedly connected with the reflection shell, and the reflection shell offers some with the contact surface of the pcb board The slot to make way corresponding with pin position.

By adopting above-mentioned technical proposal, offer towards the one side of pcb board in reflection shell some with pin position phase Corresponding slot to make way, allows pin to be embedded in slot to make way, so as to play the work for enabling pcb board to be brought into close contact with reflection shell With solving the problems, such as to make pcb board as pin is too high with the light leak caused by the closely sealed deficiency of reflection shell.

Further, on the pcb board, binding has luminescent wafer.

Used as improvement of the present utility model, the slot to make way is circular hole.

By adopting above-mentioned technical proposal, slot to make way is arranged to circular hole, is that the volume of slot to make way is slightly larger than pin Volume, so arrange make slot to make way fully accommodate pin, make PCB with reflect shell it is fully closely sealed.

Further, the contact pin is set to 8, is distributed in the both sides of pcb board.

Used as improvement of the present utility model, the adjacent contact pin of any two is parallel and is placed equidistant.

Used as improvement of the present utility model, two sides up and down of the pcb board are disposed as circuit, and the PCB is arranged There is the through hole run through for the contact pin, in the through hole, be electroplate with hole copper coating.

Circuit is provided with by adopting two sides up and down of above-mentioned technical proposal, pcb board, subtracts the volume of circuit board It is little, in order to preferably facilitate the connection between circuit, hole copper coating is electroplate with through hole, can be turned on by hole copper coating The circuit of the upper and lower both sides of lower pcb board.

In sum, this utility model has the advantages that：Offer with the contact surface of pcb board in reflection shell some The slot to make way corresponding with pin position, allows pin to be embedded in slot to make way, enables pcb board with reflection shell so as to play The effect being enough brought into close contact, solve makes pcb board ask with the light leak caused by the closely sealed deficiency of reflection shell as pin is too high Topic.
