1. Technical Field
The present disclosure generally relates to testing devices, particularly to a testing device for testing computer connector durability.
2. Description of Related Art
A typical electronic device usually includes many types of connectors, such as earphone connectors (jacks), universal serial bus (USB) connectors, etc. The connectors may be damaged if too much force is used to insert a plug or insertion is done at the wrong angle. Thus, the durability of connector needs to be tested, to ensure that damage will not occur too easily. Some devices used to test durability may include an air cylinder and a pressing head driven by the air cylinder. The air cylinder drives the pressing head to repeatedly strike or press against a plug inserted in the jack being tested a number of times at a predetermined pressure.
However, there are no adjustable universal test devices, so a different device is required for each different kind of device to be tested which is expensive and inconvenient.
Therefore, there is room for improvement within the art.
Many aspects of the disclosed testing device can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present testing device.

The base 10 defines a number of threaded holes 11 and a number of fixing holes 13. The fixing assembly 20 includes a number of holding blocks 21, a number of screws 22, a fixing board 23, a number of bolts 25 and corresponding nuts 27. In the exemplary embodiment, the fixing assembly 20 includes two pairs of holding blocks 21, two bolts 25, and two nuts 27. Each pair of the blocks 21 clamps opposite surfaces of the device 900 to hold the device 900 on the testing device 100. In the exemplary embodiment, each block 21 is substantially L-shaped, and includes a fixing portion 211 detachably mounted on the base 10 and a clamping portion 213. Each fixing portion 211 defines two parallel mounting slots 2111. Each screw 32 is located and can move longitudinally in one of the mounting slots 2111, and is screwed in one of the threaded holes 11 to fix the corresponding block 21 on the base 10. The screws 22 can be screwed in different threaded holes 11 to adjust the distance between the two pairs of holding blocks 21 to clamp different size electronic devices.
The fixing board 23 is mounted to the base 10 by the bolts 25 and the nuts 27, and is parallel to the base 10. The fixing board 23 rides on the electronic device 900 to prevent the electronic device 900 from separating from the base 10. A number of mounting holes 231 are defined through the fixing board 23. The two bolts 25 are located at opposite sides of the electronic device 900. One end of each bolt 25 is fixed in one of the fixing holes 13 of the base 10, the other end of each bolt 25 is slidably located in one of the mounting holes 231. Each nut 27 is threadedly engaged with one of the bolts 25, and resists one surface of the fixing board 23 opposite to the base 10. The bolts 25 can selectively be placed in different mounting holes 231 and the corresponding fixing holes 13 to adjust the distance between the two bolts 25, to fix different size electronic devices.

In the exemplary embodiment, one end of each supporting board 31 defines two parallel first slots 311, both of which extend along a first direction; the other end of each supporting board 31 defines a second slot 313 extending along the first direction. The adjusting assembly 30 further includes a plurality of mounting screws 36. Each mounting screw 36 is located and can move longitudinally in one of the first slots 311. One end of each mounting screw 36 is attached to the connecting board 33, the other end is bigger than the corresponding first slot 311 to retain the connecting board 33 between the two supporting boards 31. When the mounting screws 36 are loosened, the connecting board 33 can move along the first direction as the mounting screws 36 move in their corresponding first slots 311.
The connecting board 33 defines a slit 333 and a plurality of retaining holes 331 evenly distributed at two opposite sides of the slit 333. The mounting board 35 defines two third slots 351, both of which extend along a second direction perpendicular to the first direction. The two third slots 351 are respectively defined in the two opposite ends of the mounting board 35. The mounting board 35 is fixed on the connecting board 33 by two fasteners 352 which are respectively and movably located in one of the third slots 351. When the two fasteners 352 are loosened, the mounting board 35 can move along the second direction as the two fasteners 352 move in their corresponding third slots 351.
The fourth slot 353, defined between the two third slots 351, extends along a third direction perpendicular to the first direction and the second direction. In the exemplary embodiment, the mounting board 35 has three parallel fourth slots 353. The first cylinder 41 is movably mounted in one of the fourth slots 353. In the exemplary embodiment, the first cylinder 41 includes a first rod 411 movably located in one of the fourth slots 353, the adjusting assembly 30 further includes a first nut 37 threadedly engaged with the first rod 411 and resisting a bottom surface of the mounting board 35. When the first nut 37 is loosened, the first cylinder 41 can move along the third direction as the first rod 411 move in the fourth slot 353.
One end of the first rod 411 passes through the slit 333 of the connecting board 33 and faces the base 10. The first head 51 is fixed on the end of the first rod 411 and aligned with a surface of the external connector 910. Since the connecting board 33 can move relative to the supporting board 31 along the first direction; the mounting board 35 can move relative to the connecting board 33 along the second direction; the first cylinder 41 can move relative to the mounting board 35 along the third direction; and the first direction, the second direction and the third direction are perpendicular to each other, the first cylinder 41 and the first head 51 can be positioned to accommodate different size electronic devices 900.
The second cylinder 43 is movably and detachably mounted on one of the supporting board 31. In the exemplary embodiment, the second cylinder 43 includes a second rod 431 passed through and movably located in one of the second slots 313. The second head 53 is fixed to the end of the second rod 431 and is aligned with another surface of the external connector 910. The adjusting assembly 30 further includes a second nut 38 threadedly engaged with the second rod 431 and resisting an inner surface of the supporting board 31. When the second nut 38 is loosened, the second cylinder 43 can move longitudinally relative to the supporting board 31 as the second rod 431 move in the second slot 313, thus the second head 53 fixed on the second rod 431 can move to align with the external connector 910.
