Description

A kind of anti-deformation glue filling box structure

Technical field

The utility model relates to a kind of circuit board assembling field, is specifically related to a kind of anti-deformation glue filling box structure.

Background technology

Nowadays, the use that electronic product is a large amount of, people are more and more higher to the quality requirements of product, many countries have adjusted the industry standard of product, the manufacturing and the instructions for use of product have been improved, originally exposed at interiors of products, the external world can't see, just can not touch, the circuit board of energy often needs encapsulating or brush coating, just can use after the sealing fully, glue filling box just arises at the historic moment, but existing glue filling box exists compact dimensions unstable, and box body is out of shape, the PCB component assembling is loaded down with trivial details, fixing insecure or easy dress does not advance, and often loses the greater for less, and brings the loss of more time and fund.

The utility model content

The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of anti-deformation glue filling box structure is provided, and the utlity model has higher intensity, and is durable, good stability of the dimension, and not yielding, ease of assembly does not increase cost.

For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:

A kind of anti-deformation glue filling box structure comprises glue filling box body, PCB pipe position muscle group, glue filling box feet and box mouth flange.

Further, described glue filling box body is made of long side differential of the arc wall, short side differential of the arc wall and bottom differential of the arc wall.

Further, end points and 3 lines of mid point of described long side differential of the arc wall, short side differential of the arc wall and bottom differential of the arc wall circular arc respectively consist of an isosceles triangle, and the ratio of the height of this isoceles triangle shape and end length is less than 1:20, and greater than 1:200.

Further, a described PCB pipe muscle group comprises without guiding PCB buckle, has guiding PCB buckle, long side support limit muscle group, weak point side support limit muscle group and PCB to insert the guiding oblique angle.

The beneficial effects of the utility model are:

The utlity model has higher intensity, durable, good stability of the dimension, not yielding, ease of assembly does not increase cost.

Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and cooperate accompanying drawing to be described in detail as follows.The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.

Description of drawings

Accompanying drawing described herein is used to provide further understanding of the present utility model, consists of the application's a part, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model.In the accompanying drawings:

Number in the figure explanation: 1, glue filling box body, 2, a PCB pipe position muscle group, 3, the glue filling box feet, 4, box mouth flange, 5, PCB assembly, 101, long side differential of the arc wall, 102, short side differential of the arc wall, 103, bottom differential of the arc wall, 201, without guiding PCB buckle, 202, guiding PCB buckle arranged, 203, long side support limit muscle group, 204, lack side support limit muscle group, 205, PCB inserts the guiding oblique angle.

The specific embodiment

Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.

With reference to Fig. 1-shown in Figure 4, a kind of anti-deformation glue filling box structure comprises glue filling box body 1, a PCB pipe position muscle group 2, glue filling box feet 3 and box mouth flange 4.

Further, described glue filling box body 1 is made of long side differential of the arc wall 101, short side differential of the arc wall 102 and bottom differential of the arc wall 103.

Further, end points and 3 lines of mid point of described long side differential of the arc wall 101, short side differential of the arc wall 102 and bottom differential of the arc wall 103 circular arcs respectively consist of an isosceles triangle, and the ratio of the height of this isoceles triangle shape and end length is less than 1:20, and greater than 1:200.

Further, a described PCB pipe muscle group 2 comprises without guiding PCB buckle 201, has guiding PCB buckle 202, long side support limit muscle group 203, weak point side support limit muscle group 204 and PCB to insert guiding oblique angle 205.

The operation principle of present embodiment is as follows:

Long sidewall of the present utility model, short sidewall and base wall are differential of the arc shape, effectively avoided the after-contraction distortion of moulding, both improved the dimensional stability of glue filling box, also improved the wall intensity of glue filling box, arc ratio wide and camber is sandwiched between 1:20 and the 1:200 simultaneously, can guarantee to strengthen and anti-deformation, also less because of camber, the morpheme space of impact is less, the position that need not to consider in addition redesign and arrange other parts of product, the setting of box mouth flange 4 is that further brute force is avoided deformation after unloading, improve the stability of the parameters of glue filling box, add PCB without guiding PCB buckle 201 with the combination that guiding PCB buckle 202 is arranged and inserted guiding oblique angle 205, make PCB assembly 5 can need not to screw, just can snap in easily, and caught on and to be come off, the setting of long side support limit muscle group 203 and short side support limit muscle group 204 is to prevent that error from appearring in PCB assembly 5 when making, the restriction compensation of doing in advance, PCB assembly 5 is loosening when avoiding encapsulating, cause off normal, as shown in Figure 5 and Figure 6.

The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
