Description

Test carrier

The present invention relates to a test carrier, especially a test carrier for electromagnetic compatibility (EMC) testing.

Generally speaking, in order for electronic devices to operate normally in the same environment without being interfered by the magnetic fields emitted by each other, electronic devices need to undergo electromagnetic compatibility testing before they leave the factory. Electromagnetic compatibility testing mainly includes electromagnetic interference (EMI) testing and electromagnetic susceptibility (EMS) testing. Electromagnetic interference is the interference generated by electromagnetic field accompanied by the action of voltage and current, and electromagnetic immunity It is the ability of the product not to be affected by the surrounding electromagnetic environment during use.

However, the test table used to carry electronic devices in the electromagnetic compatibility test is usually made of wood or fiber reinforced plastic (FRP), and compared to air, wood and glass fiber have a higher dielectric constant. . Therefore, the accuracy of the electromagnetic compatibility test is easily affected by the test table.

The present invention is to provide a test carrier so that the accuracy of the electromagnetic compatibility test of the electronic device is less susceptible to the influence of the test carrier.

The test carrier disclosed in an embodiment of the present invention is used to carry a The electronic device includes a body and a cushion body. The body includes a bearing part and at least one supporting part. The supporting portion has a first side surface and a second side surface opposite to each other. At least one supporting portion protrudes from the first side surface of the carrying portion. The carrying part and at least one supporting part are integrally formed and made of expanded polystyrene. The cushion body is stacked on the second side surface of the supporting part and is made of polystyrene. The carrying part is used for carrying the electronic device through the cushion body.

According to the test machine disclosed in the above embodiment, since the bearing part and the supporting part are integrally formed and made of expanded polystyrene, and the dielectric constant of expanded polystyrene is close to that of air, the bearing The part and the support part are less likely to affect the accuracy of the electromagnetic compatibility test of the electronic device. In addition, since the cushion body is stacked on the second side surface of the bearing portion, the cushion body replaces the second side surface of the bearing portion to bear the wear caused by contact with the electronic device, thereby increasing the service life of the testing machine.

The above description of the content of the present invention and the description of the following embodiments are used to demonstrate and explain the principle of the present invention and provide a further explanation of the scope of the patent application of the present invention.

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 jointly form a groove 105. In addition, the supporting portion 101 and the two supporting portions 102 are integrally formed and made of expandable polystyrene (EPS).

Of course, the present invention is not limited to the number of supporting parts 102. In other embodiments, the body only includes a single support portion.

The cushion body 200 is stacked on the second side surface 104 of the supporting portion 101 and is made of polystyrene (PS). The carrying portion 101 is used to carry through the mat 200 载电子装置20。 Carrying the electronic device 20.

In this embodiment, the mounting member 300 each includes two first assembly boards 301, a carrier board 302, and a second assembly board 303, and the two first assembly boards 301 and the second assembly board 303 respectively protrude from the carrier board 302 On opposite sides.

The two supporting plates 302 respectively carry the side of the two supporting portions 102 away from the supporting portion 101, and the first fasteners 400 respectively lock the first assembly plates 301 of the two mounting members 300 to the two supporting portions 102.

In addition, in this embodiment, the two first assembling plates 301, the carrying plate 302 and the second assembling plate 303 in each mounting member 300 are integrally formed, but it is not limited thereto. In other embodiments, one of the first assembly boards is separated from the carrier board, that is, the carrier board, the other first assembly board, and the second assembly board are integrally formed, and one of the first assembly boards is independent of Components of the carrier board, another first assembly board and the second assembly board.

The movable frame 500 includes a frame body 501 and a roller 502. These second fasteners 600 fix the two second assembly plates 303 to the frame body 501 respectively, that is, the frame body 501 is fixed to a portion of the supporting part 102 away from the carrying part 101 through the second fasteners 600 and the second assembly plate 303. side. The roller 502 is disposed on the side of the frame body 501 away from the support portion 102 and is used to be carried on the bearing surface 30 so that the test carrier 10 can slide on the bearing surface 30.

In this embodiment, the test carrier 10 further includes a plurality of first nut 410 and a plurality of second nut 610. The first nuts 410 are respectively locked to the first fasteners 400 and the additional mounting member 300 is locked to the support through the first fasteners 400 The stability of section 102. The second nuts 610 are respectively locked to the second fasteners 600 to increase the stability of the second assembly board 303 being locked to the frame 501 through the second fasteners 600.

In other embodiments, the test carrier does not need to include a movable frame and the test carrier is placed on the cart so that the test carrier can slide on the bearing surface. In the embodiment in which the test carrier does not include the movable frame, the test carrier does not need to include the mounting member for installing the movable frame on the support part.

In this embodiment, the test carrier 10 further includes a plurality of supporting columns 700. The supporting column 700 is located in the groove 105, and the first side surface 103 of the supporting part 101 is supported by the supporting column 700, so as to improve the stability of the electronic device 20 carried on the supporting part 101.

Of course, the test stage 10 is not limited to include a plurality of support columns 700. In other embodiments, the test carrier includes a single support column. In still another embodiment, the test carrier does not need to include the supporting column.

According to the test machine disclosed in the above embodiment, since the bearing part and the supporting part are integrally formed and made of expanded polystyrene, and the dielectric constant of expanded polystyrene is close to that of air, the bearing The part and the support part are less likely to affect the accuracy of the electromagnetic compatibility test of the electronic device. In addition, since the cushion body is stacked on the second side surface of the bearing portion, the cushion body replaces the second side surface of the bearing portion to bear the wear caused by contact with the electronic device, thereby increasing the service life of the testing machine.

Although the present invention is disclosed as above in the foregoing embodiments, it is not intended to limit the present invention. Anyone familiar with the similar art will not depart from the essence of the present invention. Within the scope of Shenhe, some changes and modifications can be made.
