Description

Technical Field

[0001] The utility model belongs to the technical field of mobile terminal decorative piece installation, in particular to a decorative piece connection structure. Background Art

[0002] The outer surfaces of mobile terminals such as mobile phones and POS machines are connected with metal appearance decorative parts. Currently, the connection methods of metal appearance decorative parts and mobile terminal shells are mainly as follows:

[0003] The first is spot-welded nuts. Nuts are spot-welded on the inner side of the metal appearance decorative parts, and the mobile terminal housing is connected to the nuts through fasteners to achieve fixation between the metal appearance decorative parts and the mobile terminal housing. Spot-welded nuts leave weld marks on the outer surface of the metal appearance decorative parts, affecting the appearance effect, and require spray-painting to mask them. This is not only expensive, but also covers the metal texture of the metal appearance decorative parts, destroying the user experience of the metal appearance decorative parts.

[0004] The second method is glue dispensing, in which the metal exterior decorative parts and the mobile terminal shell are connected by gluing; however, under constant temperature and humidity testing, the glue will age quickly, causing the metal decorative parts and the mobile terminal shell to separate, resulting in poor reliability performance; therefore, improvements are necessary.
