Description

Blind-plugging T/R assembly test fixture

Technical Field

The invention relates to a blind-mate T/R assembly test fixture.

Background

T/R is an abbreviation for Transmitter and Receiver. The T/R component is generally used to mean a portion between a video and an antenna in a wireless transceiving system, i.e., the T/R component is connected to the antenna, and a connected video processing unit forms a wireless transceiving system.

The microwave signal interface of the T/R component of the electronic equipment usually adopts a plug-in blind plugging connection mode, the connection mode enables the installation of the T/R component in an electronic system such as a radar and the like to be simpler, the integration density of the system is improved, the system volume is reduced, the multi-port of the T/R component adopts the plug-in blind plugging connection mode, the possibility is provided for the multi-port simultaneous connection test, however, the plug-in connector usually has larger plugging force, when the multi-port is plugged, the plugging is difficult to realize by manpower, if a clamp can be designed, the plugging and the test of the port of the T/R component can be realized quickly and laborsavingly, the connector does not need to be plugged one by one when the T/R component is tested, and the test efficiency of the multi-port T/R.

The T/R assembly has small microwave port spacing and high density, common 1.85mm, 2.4mm, 2.92mm and 3.5mm and SMA joints are difficult to realize butt joint, and if the T/R assembly can be switched to the corresponding joint after blind plugging, the assembly can be conveniently tested.

Currently, a test fixture (with the name of CN 102914767B) for testing a radar TR component is provided, the T/R component is driven by a lead screw to be plugged and unplugged, and the test fixture is complex in structure, high in cost and not suitable for small-batch low-cost tests. Meanwhile, the rotary screw rod works through rotation of the screw rod, and the efficiency is low.

The current testing method mainly realizes the testing of the T/R assembly by manually plugging and unplugging the testing connector, wastes a large amount of time for the multi-channel T/R assembly, has low efficiency and is not suitable for large-batch testing.

Disclosure of Invention

The invention aims to solve the problems and provides a blind-mate T/R assembly test fixture, which adopts the principle of a slider-crank mechanism, a handle connecting rod of a push-pull fixture drives a T/R assembly to move left and right in a guide rail, realizes the quick blind-mate operation of a microwave port on the T/R assembly and a microwave port on the fixture, improves the working efficiency, and adopts the following technical scheme:

the utility model provides a blind-mate T/R subassembly test fixture which characterized in that: the T/R component can slide left and right along a horizontal track in the side support, one end of the handle connecting rod is fixedly connected with the cam, the cam is hinged with the side support, one end of the pull rod is hinged with the cam, and the other end of the pull rod is hinged with the connecting block; the port adapter box is fixedly connected to one side of the side support.

On the basis of the technical scheme, the handle connecting rod is a telescopic rod.

The invention has the following advantages: by adopting the principle of a crank slider mechanism, a handle connecting rod of the push-pull clamp drives the T/R assembly to move left and right in the guide rail, so that the quick blind plugging operation of a microwave port on the T/R assembly and a microwave port on the clamp is realized; after the single T/R component is tested, the next T/R component to be tested can be quickly detached and replaced, and therefore the working efficiency is improved. The handle connecting rod adopts a telescopic rod, so that the device can be well adapted to different insertion and extraction forces. The clamp is simple in structure principle, low in manufacturing cost and capable of saving test cost.
