Electronic apparatus and method for assembling thereof

Abstract

An electronic apparatus includes a case, an integrated circuit module, a cable and a fastener component. The case includes an opening and an accommodating space for the integrated circuit module and the fastener component installed therein. The cable is passed through the opening to be electrically connected with the integrated circuit module. The fastener component is adjacent to the opening and includes a first fastening portion and a second fastening portion for fastening the conducting cable and the circuit module respectively. Thereby, the cable and the integrated circuit module will be fastened simultaneously through the fastener component, and a one-time ultrasonic welding process is applied for assembly, thus the process will be simplified as to improve the yield rate.

Description

BACKGROUND OF THE INVENTIONField of the Invention[0001]The present invention generally relates to an electronic apparatus and, in particular to a power adapter in which the cable and the circuit board will be fastened simultaneously and a method for assembling thereof.Description of Prior Art[0002]With the progress of the times, industry designs of electronic products have been developed in a way of good appearance, high reliability and high performance. For designing the housings of conventional power products, in order to meet the requirements of molds and processes, a circuit board needs to be assembled in the housing, then two sides of the housing are combined with two side covers by a method of ultrasonic welding for a closed combination. Lastly, a cable passes through one side cover providing with an opening for electrically connected with the circuit board.[0003]However, a traditional method of assembling needs at least two processes of ultrasonic welding for jointing the hou...

AI Technical Summary

Benefits of technology

This patent is about an electronic device that uses a special fastener and ultrasonic welding process to attach the cable and integrated circuit module separately. This leads to several benefits. First, the overall strength of the device is improved by integrating the case and applying ultrasonic welding only to one side. Second, the components inside the case are fastened first to improve reliability. Third, the integrated circuit module is securely fixed at multiple sides, even in the event of impact or drop, to meet safety requirements.

Problems solved by technology

Nevertheless, ultrasonic welding is an irreversible process, that is, it cannot be recovered when finished; in other words, there is no chance for rework.

As a result, a controlling of quality must be particularly noticed when this kind of process is adapted, otherwise, abandonment will be the only way when something is wrong during the welding processes.

At last, a yield of the overall process will be lowered, and a long working hour is happened because of a complicated manufacturing process.
