AI Technical Summary

Benefits of technology

The apparatus effectively measures the maximum separation force between the housing and subsidiary element, preventing test failures caused by weak adhesive strength between the test block and the subsidiary element, providing reliable and accurate results.

Problems solved by technology

However, if the adhesive strength with the test block is not enough or the adhesive is uneven, the test block will firstly separates from the subsidiary element before the subsidiary element is separated from the housing.
This will result in a test failure.

Embodiment Construction

[0011]The present test apparatus is illustrated by testing a portable electronic device, in an exemplary embodiment, such as a mobile phone.

[0012]FIG. 1 shows a portion of a mobile phone 90 including a housing 92 and a subsidiary element 94. The subsidiary element 94 contributes to the external decorative appearance of the housing 92. The housing 92 is made of plastic material, and includes a barrel portion 93. The housing 92 has a covered area 920 and a plurality of through holes 922 defined on the covered area 920. The subsidiary element 94 may be attached to the covered area 920 of the housing 92 by, for example, melting, ultrasonic welding, adhering or latching.

[0013]Referring to FIG. 2, the test apparatus 100 is used for testing the maximum separation force between the housing 92 and the subsidiary element 94. The test apparatus 100 includes a positioning apparatus 50, a push mechanism 60 and a test machine 70 (only a portion of which is shown).

[0014]Referring to FIG. 3, the po...

Abstract

A test apparatus for testing a separation force between a housing (92) and a subsidiary element (94) of a portable electronic device (100). The housing defines a plurality of through holes. The subsidiary element is attached to the housing, and covers the through holes. The test apparatus includes: a positioning apparatus (50), a push mechanism (60) and a test machine (70). The positioning apparatus positions the housing with the subsidiary element therein. The push mechanism includes a support board (62) and a plurality of rods (64). The rods are mounted in the support board. The rods pass through the through holes and resisting the subsidiary element. The test machine provides a driven force to press the support board to separate the subsidiary element from the housing.

Description

BACKGROUND[0001]1. Field of the Invention[0002]The present invention generally relates to test apparatus and, particularly, to a test apparatus and method for testing a separation force between a housing and a subsidiary element in a portable electronic device.[0003]2. Description of Related Art[0004]At present, a portable electronic device usually have a decorative subsidiary element to provide an attractive appearance. The subsidiary element is generally attached to a housing of the portable electronic device by for example melting, ultrasonic welding, adhering or latching. To prevent the subsidiary element from separating from the housing due to accidental impacts, the maximum separation force between the subsidiary element and the housing generally needs to be tested to see whether the tested force is adequate.[0005]A typical testing apparatus adopts a test block for adhering to the subsidiary element. The test block is connected to a test machine. The test machine pulls the tes...
