Description

Technical Field

[0001] The utility model relates to the technical field of antenna test devices, and particularly relates to a test tooling for a radio frequency antenna without a buckle connector. Background Art

[0002] A coaxial cable + FPC / PCB is a common structure of a radio frequency antenna. One end of the coaxial cable in this radio frequency antenna is welded to the FPC / PCB, and the other end is connected to the whole machine through a buckle connector, so as to realize the connection between the antenna radiation unit and the whole machine. That is, in most cases, the non-welded end of the coaxial cable is with a buckle connector, and when the factory tests the RF performance of the antenna, there is a special test head to adapt to the buckle connector on the coaxial cable. However, in a few cases, only the wire stripping treatment is carried out at the other end of the coaxial cable, without a buckle connector. Currently, there is no special test tooling to adapt to this radio frequency antenna without a buckle connector, resulting in low test efficiency. Content of the Utility Model

[0003] The technical problem solved by the utility model is to provide a test tooling that can adapt to a radio frequency antenna without a buckle connector.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is: a test tooling for a radio frequency antenna without a buckle connector, comprising:

[0006] A pressing plate, which is located above the base, and the bottom surface of the pressing plate has a pressing protrusion corresponding to the contact groove;

[0007] A driving member, which is connected to the pressing plate to drive the pressing plate to move up and down.

[0008] In one embodiment, it further includes a machine table, and the base and the driving member are respectively connected to the machine table.

[0009] In one embodiment, the contact groove has a first through hole for the first conduction probe to penetrate and a second through hole for the second conduction probe to penetrate.

The first conduction probe and the second conduction probe are both fixedly connected to the insulating fixing block, and the first conduction probe and the second conduction probe are both electrically connected to the circuit board.

[0010] In one embodiment, a pick-and-place groove communicating with the placement groove is arranged on the base.

[0011] In one embodiment, the pick-and-place grooves are respectively arranged on two opposite sides of the placement groove.

[0014] In one embodiment, the first conduction probe is located on one side of the second conduction probe close to the limiting groove, and the top end of the first conduction probe is arranged lower than the top end of the second conduction probe.

[0015] In one embodiment, a sinking groove is provided at one end of the contact groove close to the limiting groove, and the first conduction probe is located at the sinking groove.

[0016] In one embodiment, the driving member is an electric push rod or a cylinder.

[0017] The beneficial effects of the present utility model are as follows: The structure of the non-button joint radio frequency antenna test tooling of the present utility model is novel.
