Description

Technical Field

[0001] This application belongs to the field of cable assembly testing, and more specifically, relates to a withstand voltage test tooling for the dielectric of SMP type RF cable assemblies. Background Art

[0002] Currently, after some cable assemblies are manufactured, dielectric withstand voltage performance tests need to be carried out. Among them, SMP type RF connectors are widely used in various single-unit products due to their small size and good microwave signal transmission performance. SMP type RF cable assemblies account for about 30% of the total amount of all RF cable assemblies.

[0003] In the related art, the dielectric withstand voltage test operation of SMP type RF cable assemblies requires the cooperation of 2 people at the same time. One probe of the withstand voltage tester is connected to the inner conductor of the SMP type RF cable assembly connector, and the other probe is connected to the outer shell of the SMP type RF cable assembly connector. However, this method has low test efficiency, and the probe pins of the instrument directly touch the inner and outer conductors of the connector, which is extremely easy to damage the inner and outer conductors of the connector, resulting in the scrapping of the RF cable assembly. At the same time, due to the short distance between the inner and outer conductors of the SMP type RF cable assembly connector, it is easy for the positive and negative probes of the withstand voltage tester to touch and short-circuit during testing, causing internal damage to the connector and the cable. Summary of the Utility Model

[0004] Aiming at the defects of the prior art, this application provides a withstand voltage test tooling for the dielectric of SMP type RF cable assemblies, aiming to solve the problems of low test efficiency and easy product damage of existing SMP type RF cable assembly connectors.

[0005] A withstand voltage test tooling for the dielectric of SMP type RF cable assemblies provided by this application specifically includes a bracket, a metal plate, a mating connector, and two terminal posts. The metal plate is fixedly connected to the bracket. The mating connector is arranged on the metal plate and is connected and adapted to the SMP type RF cable assembly connector. Both of the two terminal posts are arranged on the bracket. The inner conductor of the SMP type RF cable assembly connector is electrically connected to one of the terminal posts through the mating connector, and the outer conductor of the SMP type RF cable assembly connector is electrically connected to the other terminal post through the mating connector and the metal plate.

[0006] Through the above technical solution conceived by this application, compared with the prior art, by connecting the SMP type RF cable assembly connector to the mating connector and using a withstand voltage tester to connect the two terminal posts, the quick connection between the withstand voltage tester and the inner and outer conductors of the SMP type RF cable assembly connector can be completed, so that the test of the SMP type RF cable assembly can be carried out. This application makes the connection method between the withstand voltage tester and the inner and outer conductors of the SMP type RF cable assembly simpler, improves the detection efficiency, and can be operated by a single person, reducing the labor cost. At the same time, it can avoid product damage caused by accidental touch.

[0007] As a further preference, a plurality of the plug connectors are provided, and the plurality of plug connectors are uniformly arranged in an array on the metal plate.

The inner contact is arranged inside the outer contact, and the insulating member is arranged between the outer contact and the inner contact.

Through the setting of the positioning groove, the insertion angle of the SMP type radio frequency cable assembly connector can be accurate, and the connection efficiency and connection stability are improved.

[0015] As a further preference, both of the two terminal posts are fixedly connected to the bracket.

[0016] By adopting the above technical solution, the terminal posts are stored and carried together with the bracket, which is convenient for immediate use and improves the detection efficiency.

[0017] As a further preference, both of the two terminal posts are detachably connected to the bracket.

[0018] By adopting the above technical solution, since the terminal posts protrude outside the bracket, after the device is used, the terminal posts can be removed and stored to avoid damage during the storage of the device.

[0019] As a further preference, a first metal block electrically connected to the outer contact member and a second metal block electrically connected to the inner contact member are provided inside the bracket.
