Test carrying platform

Technical Field

The present invention relates to a test stage, and more particularly, to a test stage for electromagnetic compatibility (EMC) testing.

Background

Generally, in order to make electronic devices operate normally in the same environment without interference from magnetic fields generated by each other, the electronic devices need to be tested for electromagnetic compatibility before shipping. The electromagnetic compatibility test mainly includes an electromagnetic interference (EMI) test and an electromagnetic compatibility (EMS) test, wherein the EMI is interference generated by electromagnetic fields accompanied by voltage and current, and the EMS is the ability of a product to be protected from the surrounding electromagnetic environment during use.

However, the test table for carrying electronic devices in the electromagnetic compatibility test is usually made of wood or Fiberglass (FRP), and the wood and fiberglass have higher dielectric constants than air. Therefore, the accuracy of the electromagnetic compatibility test is easily affected by the test table.

Disclosure of Invention

The invention provides a test carrier, so that the accuracy of the electromagnetic compatibility test of an electronic device is less susceptible to the test carrier.

The test carrier disclosed in one embodiment of the invention is used for carrying an electronic device and comprises a body and a pad body. The body comprises a bearing part and at least one supporting part. The bearing part is provided with a first side surface and a second side surface which are opposite to each other. At least one supporting part protrudes out of the first side surface of the bearing part. The bearing part and at least one supporting part are integrally formed and made of expanded polystyrene. The pad body is superposed on the second side surface of the bearing part and is made of polystyrene. The bearing part is used for bearing the electronic device through the cushion body.

According to the testing machine disclosed in the above embodiment, since the bearing portion and the supporting portion are integrally formed and made of the expanded polystyrene, and the dielectric constant of the expanded polystyrene is close to that of air, the bearing portion and the supporting portion are less likely to affect the accuracy of the electromagnetic compatibility test of the electronic device. Moreover, the pad body is overlapped on the second side surface of the bearing part, so that the pad body can replace the second side surface of the bearing part to bear the abrasion caused by contacting the electronic device, and the service life of the testing machine is further prolonged.

The foregoing summary of the invention, as well as the following detailed description of the embodiments, is provided to illustrate and explain the principles of the invention and to provide further explanation of the invention as claimed.

In the present embodiment, the test carrier 10 is used for carrying an electronic device 20 to be tested for electromagnetic compatibility, and the test carrier 10 includes a main body 100, a pad 200, two mounting members 300, a plurality of first locking members 400, a movable frame 500, and a plurality of second locking members 600.

The body 100 includes a supporting portion 101 and two supporting portions 102. The carrier 101 has a first side 103 and a second side 104 opposite to each other. The two supporting portions 102 protrude from the first side surface 103 of the supporting portion 101 and are separated from each other, so that the two supporting portions 102 and the supporting portion 101 together form a groove 105. In addition, the supporting portion 101 and the two supporting portions 102 are integrally formed and made of Expanded Polystyrene (EPS).

However, the number of the supporting portions 102 is not limited in the present invention. In other embodiments, the body includes only a single support.

The pad 200 is stacked on the second side 104 of the supporting portion 101 and made of Polystyrene (PS). The carrier 101 is used for carrying the electronic device 20 through the pad 200.

In the embodiment, each of the mounting members 300 includes two first assembly plates 301, a carrier plate 302 and a second assembly plate 303, and the two first assembly plates 301 and the second assembly plates 303 respectively protrude from two opposite sides of the carrier plate 302.

The two supporting plates 302 respectively support one side of the two supporting portions 102 away from the supporting portion 101, and the first locking members 400 respectively lock the first assembling plates 301 of the two mounting members 300 to the two supporting portions 102.

In addition, in the embodiment, the two first assembly plates 301, the carrier plate 302 and the second assembly plate 303 of each mounting member 300 are integrally formed, but not limited thereto. In other embodiments, one of the first assembly plates is separate from the carrier plate, that is, the carrier plate, the other first assembly plate and the second assembly plate are integrally formed, and the one of the first assembly plates is a separate component from the carrier plate, the other first assembly plate and the second assembly plate.

The movable frame 500 includes a frame 501 and a roller 502. The second locking members 600 respectively fix the second assembling plate 303 to the frame body 501, that is, the frame body 501 is fixed to a side of the supporting portion 102 away from the bearing portion 101 through the second locking members 600 and the second assembling plate 303. The roller 502 is disposed on a side of the frame 501 away from the supporting portion 102, and is used for being carried on the carrying surface 30 so that the test stage 10 can slide on the carrying surface 30.

In the present embodiment, the test carrier 10 further includes a plurality of first nuts 410 and a plurality of second nuts 610. The first nuts 410 are respectively locked to the first locking members 400 to increase the stability of the mounting member 300 locked to the supporting portion 102 by the first locking members 400.
