Description

Housing of electronic device

The present invention relates to a housing, and more particularly to a housing for an electronic device.

The housing of the electronic device, such as a mobile phone case, a tablet case, etc., is usually fixed by different housings. For example, in order to improve the signal receiving quality, a housing made of plastic is usually disposed around the antenna receiving the signal to reduce the shielding of the antenna signal by the metal casing. The plastic housing and the metal housing are usually bonded using a heat-curing glue or directly assembled by screws. However, due to the inconsistent heat shrinkage rate between plastic and metal, after bonding with heat-curing glue, the plastic shell and the metal shell may be misaligned during heating and cooling, and the fitting gap is easily generated by screw assembly, so the influence is affected. The visual effect of the electronic device housing and the yield of the product.

In view of the above, it is necessary to provide a housing that reduces the fit clearance and enhances the visual effect.

A housing for an electronic device includes a first housing having an opening, a second housing mounted to the opening of the first housing, and a fastener securing the first housing and the second housing. The housing further includes an elastic member, a pressing member and an adjusting member, the elastic member is mounted on the first housing, the second housing is abutted on the elastic member, and the pressing member is pressed against the first The second housing is fixedly coupled to the first housing such that the elastic member and the second housing are interposed between the first housing and the pressing member. The adjustment member is adjustablely passed through The pressing member is in contact with the second housing to adjust the movement of the adjusting member toward the second housing, thereby adjusting a gap between the first housing and the second housing.

The housing of the electronic device is assembled and assembled with the elastic member by the pressing of the pressing member and the second housing when the first housing and the second housing are assembled, and when the pressing member is pressed In the case of the two housings, the elastic member applies a reverse force to the second housing, so that the gap in the assembly between the first housing and the second housing is automatically adjusted. In addition, by adjusting the adjusting member, the resisting force of the adjusting member against the second housing can be changed, so that the resisting force of the second housing against the elastic member and the first housing is adjusted, and the first housing and the second housing are further adjusted. The gap between the bodies improves the yield of the product and improves the appearance of the casing.
