Test Fixture

The invention relates to a test fixture, in particular to a test fixture installed in a cabinet and used for quantitatively testing various situations in which the push-pull slides on the carrier tray of the cabinet.

In an electronic device such as a server, an electronic component is usually disposed on a carrier, and the carrier is slidably disposed in a cabinet of the electronic device by a slide rail. Therefore, during the operation of the electronic device, the operator can pull the carrier tray out to maintain the electronic components, and then push the carrier tray back into the cabinet.

However, in the process of pushing and pulling the carrier disk, the entire electronic device is inevitably subjected to impacts such as impacts, which may cause abnormal operation of the electronic components. Therefore, in the manufacturing process of the electronic device, it is necessary to test the operation of the electronic component in the carrier disk after being impacted in the case of pushing and pulling the carrier disk to ensure the quality reliability of the electronic device.

For the above-mentioned impact test, it is currently carried out by manually pushing and pulling the carrier disk. However, the force used in the manual push-pull load is light and heavy and cannot be quantified, resulting in the test results not having good accuracy.

In view of the above problems, the present invention provides a test fixture, It is installed in the cabinet and can quantitatively test the operation of the electronic components that are pushed and pulled in the carrier tray of the cabinet.

The invention discloses a test fixture for being mounted in a cabinet and detachably connected to a carrier tray slidingly disposed on one of the cabinets. The test fixture includes a first bracket, a second bracket, a pulley assembly, a wire and a load. The first bracket extends along a width of one of the cabinets. Both ends of the first bracket are disposed in the cabinet. The second bracket extends along a height of one of the cabinets. The second bracket is disposed on the first bracket in a relative position adjusted in the height direction. The pulley assembly is disposed on the second bracket. The wire is slidably disposed on the pulley assembly and has a first end and a second end. The first end is detachably coupled to the carrier tray. The load is alternatively mounted to the second end.

According to the test fixture of the present invention, it is possible to simulate the force of the push-pull disk by releasing the load to be subjected to gravity and using the pulley assembly to change the direction of the wire. And by replacing the load of the specified weight, the need to quantify the force of the push-pull tray is achieved. This can improve the accuracy of the test. In addition, in addition to being able to assist in testing the operation of the electronic components in the carrier, such a test fixture can verify the design strength of the carrier itself and verify the design strength between the carrier and the cabinet. In addition, the first bracket can be disposed in the first bracket by adjusting the relative position in the height direction, so that the pulley assembly can correspond to the carrier trays of different sizes.

Before the test, the position of the second bracket 12 relative to the first bracket 11 can be adjusted in the height direction H, so that the pulley assembly 15 can correspond to the different size specifications of the carrier tray 30, such as 1U (= 1.75 inch = 4.445 cm), 2U, 3U, 4U or even 5U carrier tray 30. Next, the carrier tray 30, the wire 18 and the load 19 are mounted, and the load 19 is first supported by a clamp (not shown).

During the test, the clamp releases the load 19, causing the load 19 to be subjected to gravity. The load 19 moves downward in the direction of gravity (parallel to the height direction H in this embodiment), and the pulling wire 18 is moved. The pulley 152 changes the direction in which the wire 18 extends, causing the wire 18 to pull the carrier disk 30 in the length direction L. At this time, the carrier 30 is pulled back by the force of the weight of the load 19 to simulate the situation in which the force similar to the weight of the load 19 is pushed against the carrier 30, so that the tester can detect the setting on the carrier 30 at this time. The operation of electronic components. In addition, the tester is more able to select various weights of load 19, and can simulate different force pushes. The usage context of the carrier 30 is offset. In addition, the design strength of the carrier tray 30, the design strength of the slide rail 21 itself, and the mounting strength between the slide rail 21 and the cabinet 20 can also be verified under repeated simulation tests. Furthermore, the tester can install a robot arm or a piston mechanism between the test fixture 1 and the carrier tray 30, and can verify the life of the slide rail 21 under a specified thrust.

When the test fixture 1 is to be removed, it is only necessary to disassemble the wire 18 and the carrier tray 30 and pull the latch 111 away from the first bracket 11.

In summary, the test fixture of the present invention can simulate the force of the push-pull tray by releasing the load to be subjected to gravity and using the pulley assembly to change the direction of the wire. And by replacing the load of the specified weight, the need to quantify the force of the push-pull tray is achieved. This can improve the accuracy of the test. In addition, the test fixture can verify the design of the carrier itself, the design strength of the rail itself, and the mounting strength between the rail and the cabinet. When the test fixture is to be removed, only the wire and the carrier plate need to be disassembled, and the pin can be pulled out of the first bracket, and the test fixture can be quickly disassembled. In addition, the first bracket can be disposed in the first bracket by adjusting the relative position in the height direction, so that the pulley assembly can correspond to the carrier trays of different sizes.

Although the present invention has been disclosed above in the foregoing embodiments, it is not intended to limit the invention. It is within the scope of the invention to be modified and modified without departing from the spirit and scope of the invention.
