BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a test fixture, and more particularly to a test fixture adapted for holding an electronic device.

2. The Related Art

To ensure that electronic devices can operate normally and steadily in long usage duration, the electronic devices usually need to undergo various quality control (QC) tests before mass production or leaving the factory. Even though some of the QC tests have already been executed by the test machines before assembly, some of the QC tests still need to be done after the assembly of the electronic devices, for example, the antenna mounted on the electronic device which is easy to be affected by ambience. Therefore, it is desirable to design a test fixture especially adapted for testing the antenna characteristic of the electronic devices.

SUMMARY OF THE INVENTION

Accordingly, an object of the present invention is to provide a test fixture especially adapted for testing an antenna characteristic of an electronic device.

The test fixture is mounted to a supporting base and adapted for holding the electronic device, such as a laptop computer, a mobile phone and so on, on purpose of testing an antenna characteristic of the electronic device. The test fixture includes a first fixing component and a second fixing component. The first fixing component is adapted for being mounted to the supporting base and has a first basic plate adapted for carrying the laptop computer. The second fixing component is removably mounted to the first fixing component, and has a plurality of supporting rods suspending above the first basic plate adapted for clamping the mobile phone therebetween.

As described above, the first fixing component mounted to the supporting base has the first basic plate used for carrying the electronic device of biggish size, such as the laptop computer. Such structure is a simple, and easy to be manufactured and assembled. Meanwhile, the second fixing component with the supporting rods is removably mounted on the first fixing component, which is enabled to fix the electronic device of small size, such as the mobile phone. Thus the test fixture can fix the electronic devices of different sizes, which enlarges the application range thereof.

DETAILED DESCRIPTION OF THE EMBODIMENT

With reference toFIG. 1andFIG. 2, a test fixture of an embodiment according to the present invention is shown. The test fixture mounted on a supporting base (not shown) for holding an electronic device (not shown) includes a first fixing component10and a second fixing component20mounted on the first fixing component10.

The first fixing component10includes a first basic plate11and a first fixing plate12extending perpendicularly from an end of the first basic plate11. The first basic plate11defines a plurality of through holes111adapted for fixing the second fixing component20and the electronic device. In this embodiment, the first basic plate11has more through holes111arranged regularly for lighting the weight of the first fixing component10. Thereinto, there are nine through holes111arranged in a matrix manner in the center of the first basic plate11, four through holes111are disposed symmetrically at two sides of the first basic plate11, and eight through holes111are evenly arranged at four corners of the first basic plate11. Meanwhile, the first basic plate11has two buckling holes112at two opposite sides thereof, respectively. Each of the buckling holes112receives an end of a sliding rod13.

The first fixing plate12is substantially a triangle shape, and has a wire hole121at a center thereof for allowing a test cable (not shown) passing therethrough to transmit signal, and a plurality of fixing holes122around the wire hole121for fixing the first fixing component10to the supporting base firmly. In this case, a plurality of screws (not shown) is adapted to engage the supporting base with the fixing holes122for fastening the first fixing component10to the supporting base. A bottom portion of the first fixing plate12has two through holes123at two ends thereof. In this case, a tape may be adapted to pass through the through holes123and111for fastening the electronic device to the first basic plate11firmly.

A stopping member30is slidably mounted on the sliding rods13. The stopping member30includes a sliding element31and a stopping element32. The sliding element31has an upper portion311and a bottom portion312coupled with the upper portion311. The upper portion311is a rectangular shape and has two thread holes3111at a top thereof. The thread holes3111extend upwardly and downwardly, and pass through the whole upper portion311. One side of the upper portion311opposite to the first basic plate11defines a stopping hole3113arranged between the thread holes3111and extending toward the other side thereof. A bottom surface of the upper portion311has two sliding recesses3112. The sliding recess3112extends parallel to the stopping hole3113and passes through the whole bottom surface of the upper portion311. The bottom portion312is analogous to the upper portion311except that the bottom portion312doesn't have the stopping hole. Two screws (not shown) are adapted to pass through the thread holes3111and3121for connecting the upper portion311and the bottom portion312together. The sliding recess3112faces the corresponding sliding recess3122to form a through hole for allowing the sliding rod13to pass therethrough. Thus the sliding element31is moved and fixed on the sliding rods13optionally via adjusting the screws. In addition, it should be noted that the upper portion311might be integrated with the bottom portion312for meeting different demands and should not be limited.

The stopping element32defines a rectangular stopping plate321. One end of the stopping plate321extends outwards to form two stopping arms322spaced away from each other. The other end of the stopping plate321bends downwardly to form a holding plate323with a holding hole3231defined thereon. The holding hole3231has a larger dimension in cross section than that of a screw (not shown) in a direction perpendicular to the stopping plate321for allowing the screw to be movable therealong. The stopping plate321is disposed on the sliding element31with the stopping arms322exceeding the sliding element31. The holding plate323is attached to a side of the sliding element31opposite to the first basic plate11with the screw passed through the holding hole3231and the stopping hole3113for connecting the sliding element31and the stopping element32together. The stopping element32can be moved upwards and downwards relative to the screw in the holding hole3231to adjust the height of the stopping arm322with respect to the electronic device until the stopping arms322abut a top of the electronic device.

The second fixing component20defines a second basic plate21and a second fixing plate22bending upwards from an end of the second basic plate21. The second basic plate21is rectangular and has two installing holes211corresponding to the through holes111for fixing the second fixing component20to the first fixing component10via screws (not shown). The second fixing plate22is substantially rectangular with a top side thereof shaped to show an arc shape similar to that of the first fixing plate12. A wire hole221is opened in the center of the second fixing plate22corresponding to the wire hole121for allowing a test cable (not shown) to pass therethrough to transmit signal. The wire hole221is surrounded by a plurality of supporting holes222. The supporting holes222are arranged symmetrically with the same distance in horizontal direction and adapted for fixing supporting rods23. The supporting rods23are all slender. It should be noted that the second fixing component might be just a rectangular plate with a plurality of supporting rods mounted thereon and a plurality of installing holes formed thereon. Accordingly, the first fixing plate of the first fixing component has a plurality of engaging holes corresponding to the installing holes for removably fastening the second fixing component to the first fixing component via screws.

Please refer toFIG. 2andFIG. 3, when the test fixture is used to test an antenna characteristic of a laptop computer, an upper cover4of the laptop computer is placed on the first basic plate11and blocked by the first fixing plate12. The stopping members30are moved toward the upper cover4until the sliding elements31abut two sides of the upper cover4. The stopping elements32are adjusted in a vertical direction so that the stopping arms322abut a top surface of the upper cover4. Thus the upper cover4is mounted to the test fixture firmly.

Please refer toFIG. 2andFIG. 4, when testing an antenna characteristic of a mobile phone5, the second fixing component20is mounted to the first fixing component10. The supporting rods23are inserted into the corresponding supporting holes222for clamping the mobile phone5therebetween. In addition, a tape (not shown) may be provided to wrap the mobile phone5and the supporting rods23in order to fix the mobile phone5to the supporting rods23firmly.

As described above, the first fixing component10mounted to the supporting base has the first basic plate11used for carrying the electronic device, the first fixing plate12and stopping member30used for positioning and fixing the electronic device of biggish size, such as the laptop computer. Such structure is a simple, and easy to be manufactured and assembled. Furthermore, the stopping member30can be moved on the sliding rods13, which makes the first fixing component10fix the electronic devices of different sizes. Meanwhile, the second fixing component20with the supporting rods23is removably mounted on the first fixing component10, which is enabled to fix the electronic device of small size, such as mobile phone5. Thus the test fixture can fix the electronic devices of different sizes, which enlarges the application range of the test fixture.
