Embodiment Construction

[0010] one This kind of test head includes a shell 4, two insulators (2, 3) are arranged in the inner cavity of the shell 4, there is a concentric through hole in the middle of the two insulators, a double-ended pin 1 is arranged in the through hole, and one end of the pin is connected to the Test the connection of the RF coaxial connector, and the other end is connected with the testing equipment; the outer wall of the shell 4 is covered with a screw sleeve 5, the outer wall of the shell 4 is provided with an annular groove, and the inner wall of the corresponding screw sleeve 5 is provided with an annular groove. A snap ring 6 is arranged between the grooves.

[0011] Such as figure 1 Shown: a test head, including: pin 1, insulator 2, insulator 3, shell 4, screw sleeve 5, snap ring 6 according to the size of the outer diameter of both ends of the pin 1, press them into the insulator 2 in turn, the insulator 3. There is a knurling or barb in the middle of the thinner end o...

Abstract

The invention relates to a test head used for testing performance of a radio frequency coaxial connector. The test head solves the technical problems that an existing connector is complex in structure, multiple in connecting link, large in size, high in cost and the like. The test head is characterized by comprising an outer shell (4), two insulators (2 and 3) are arranged in an inner cavity of the outer shell (4), concentric through holes are formed in the centers of the insulators, a double-headed inserting needle (1) is arranged in the through holes, one head of the inserting needle (1) is connected with the radio frequency coaxial connector to be tested, the other head of the inserting needle (1) is connected with test equipment; a wire thread insert (5) is sleeved on an outer wall of the outer shell (4), an annular groove is formed in the outer wall of the outer shell (4), an annular groove corresponding to the annular groove formed in the outer wall of the outer shell (4) is formed in an inner wall of the wire thread insert (5), and a clamping ring (6) is arranged between the annular groove formed in an inner wall of the wire thread insert (5) and the annular groove formed in the outer wall of the outer shell (4). The test head is simple in structure, few in connecting link and convenient to use. Meanwhile, due to the fact that the test head has a little effect on a test process, error is minimum and obtained test results are closest to actual work technical parameters of the radio frequency coaxial connector when the technical performance of the radio frequency coaxial connector is tested.

Description

technical field [0001] The invention relates to a test head for testing the performance of a radio frequency coaxial connector. Background technique [0002] The RF coaxial connector used in communication equipment needs to be tested for its actual technical performance parameters when the product leaves the factory and is used. When testing, the RF coaxial connector needs to be connected with the testing equipment. If the RF coaxial connector is directly connected to the detection equipment, the shielding is poor, and the detection process is susceptible to interference and large errors, so it is necessary to use a dedicated detection connector for connection. Most of the existing detection connectors have complex structures, many connection links, large volume, and high cost. At the same time, because the actual working conditions of the RF coaxial connectors have been changed to a certain extent, the test results cannot truly and completely reflect the Measure the actual...
