Problems solved by technology

[0003] Usually, the fixation of the nut generally has the following two solutions: one is to directly implant the copper nut into the plastic by in-mold injection molding during injection molding, but this solution is difficult to position the nut by in-mold injection molding because the nut is too small; There is a risk of dropping and damaging the mold; the second is to melt the copper nut into the plastic in the strap hole, but the tension of the hot melt nut cannot reach 10KG

Embodiment Construction

[0030] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings.

[0031] see Figure 1 to Figure 4 As shown, the housing of the present application includes a metal frame 10 provided with a mounting groove 12, an insulator 20 formed inside the metal frame 10, and a nut 30 formed in the insulator 20 and exposed in the mounting groove 12. .

[0032] When the housing is used as a smart watch housing, the mounting groove 12 is a watch strap mounting hole, and both ends of the mounting groove 12 are embedded with nuts 30 in the insulator 20 .

[0033] The metal frame 10 also includes an outer surface 11 after CNC finishing, and two ends of the mounting groove 12 are provided with surrounding holes 16 (refer to image 3 , Figure 7 As shown), the n...

Abstract

The invention discloses a shell, and the shell comprises a metal frame body, wherein the metal frame body is provided with a surrounding hole; an insulator which is formed on the inner side of the metal frame body; and a nut which is arranged in the surrounding hole and wrapped by the insulator. The nut comprises a nut body and an internal threaded hole formed in the nut body, and the space between the periphery of the nut body and the inner wall face of the surrounding hole is filled with an insulator, so that the nut can be isolated from the metal frame. The invention further provides a shell manufacturing method.

Description

technical field [0001] The present application relates to the fields of metal processing and injection molding, in particular to a casing and a method for manufacturing the casing. Background technique [0002] Smart watches are already a mainstream consumer electronics product. In order to increase the quality of the smart watch, a large number of metal frames have been used as the casing. However, the following problems are faced during the manufacturing process. There is a strap for installing the strap inside the casing. hole, and the watch strap is required to be directly locked in the watch strap hole by screws, and the nut in the watch strap hole cannot come into contact with the metal case, and the pulling force of a single nut needs to be above 10KG. [0003] Usually, the fixation of the nut generally has the following two solutions: one is to directly implant the copper nut into the plastic by in-mold injection molding during injection molding, but this solution is...
