Description

Three proofings electronic product seal structure

Technical Field

The utility model relates to an electronic product waterproof field especially relates to a three proofings electronic product seal structure.

Background

The portable three-prevention electronic terminal is required to reach a certain protection standard in three aspects of dust prevention, shock prevention and water prevention, can bear certain external force impact in an actual use scene, and can also keep the established dust prevention and water prevention requirements under the impact. Particularly for parts in which removable attachment is required, such as battery cases, data card covers, and the like; currently, the shell is normally pressed positively or laterally by a ring of the shell and a rubber ring, and the structural modes all require that the shell has high strength and rigidity, which requires increasing the thickness and space of product materials or using more expensive rigid materials (as shown in fig. 1 and fig. 2). The size and the weight of the product can be greatly increased, the carrying convenience is reduced, and the product functionality and the product competitiveness are reduced.

Fig. 1 and 2 show the conventional positive pressure sealing method in the industry: the upper cover 1 and the lower cover 2 of the shell are on a horizontal joint surface, and waterproof and dustproof sealing is realized in a way that the rubber pad 3 is pressed by force; as shown in the figure, the housing upper cover 1 is pressed upward by the lower rubber pad 3 and by the downward force F for locking the upper cover 1. F is continuously distributed, external locking force F (usually a screw, a knob and other structures) is distributed at intervals, a bending moment is formed on the upper cover 1 under the action of F and F, if the rigidity of the upper cover 1 is insufficient, the shell is deformed, and sealing is invalid, so that the wall thickness of the upper cover 1 is thickened to ensure the sealing effect, and the increasingly light and thin market demand of the machine is influenced;

fig. 3 shows another commonly used pressure measuring sealing method in the industry: the upper cover 1 and the lower cover 2 of the shell are arranged on a vertical joint surface, and waterproof and dustproof sealing is realized in a lateral extrusion mode through the rubber pad 3; as shown in the figure, the vertical cantilever receives a horizontal pushing force f when the housing upper cover 1 is in a compressed state. Under the effect of f power, form a clockwise bending moment to casing

upper cover

1, 1 vertical planes of casing upper cover and horizontal plane all can the bending deformation trend, if 1 material rigidity of upper cover is not enough, the casing warp, sealed the same inefficacy, so for guaranteeing sealed effect, will thicken 1 material wall thickness of upper cover, influence the increasingly frivolous market demand of machine.
