Description

Technical Field

[0001] The present invention belongs to the field of communication technologies, and particularly relates to an integrated tool for positioning the interface of a radio frequency connector and correcting the microstrip direction, and a method for using the same. Background Art

[0002] A radio frequency connector is a commonly used circuit component, usually installed on a cable or a device, and is a separable component for electrical connection of a transmission line system. The interface size of a radio frequency connector is an important dimension to ensure reliable plug-and-socket connection and good interchangeability. Its effective contact part is the end face of the pin step and the jack. If the pin step is too long, the end face of the jack and the step will be squeezed against each other during connection, resulting in deformation and affecting impedance continuity. In severe cases, damage will occur. If the pin step is too short and the end face distance is too far, it is equivalent to a sudden reduction in the inner conductor diameter, which also affects the impedance. In order to ensure the stability of product performance during mass production, usually there must be a certain distance at the end face, and the shorter this distance is within the allowable range of the machinery industry, the better. Therefore, the connector has relatively high requirements for the interface size, and the product technical standard requires that the interface size of the interface is 0 mm to 0.25 mm. The correctness of the microstrip direction of a radio frequency connector can reduce signal reflection and loss, ensure the integrity of signal transmission, and the accuracy of the correction tool directly affects the accuracy of the test results. Therefore, a high-quality tool should be selected. The microstrip correction tool plays a crucial role in the design and test of radio frequency and microwave circuits and can effectively improve the performance and reliability of the circuit. The radio frequency connector drawing requires that the microstrip be completely parallel to the flange surface. When the product is used, after the flange is fixed, the microstrip is inserted into the corresponding jack slot.

[0003] In the prior art, for the microstrip direction of a radio frequency connector, workers usually use tweezers to clamp the microstrip and rotate it to adjust the microstrip direction. This method extremely depends on the experience of workers and cannot reliably ensure that the microstrip direction is parallel to the flange. How to solve the above technical problems and how to design a new type of integrated positioning device for the microstrip of a radio frequency connector have long troubled the technicians in this field. Summary of the Invention

[0004] In view of the above technical problems, the present invention provides an integrated positioning device for the microstrip of a radio frequency connector. This device can effectively position the direction and interface size of the microstrip and the flange, avoid human errors during product assembly positioning, solve the problem of inconsistent microstrip direction and flange direction on the one hand, and solve the problem of interface size variation during microstrip adjustment on the other hand, improving the qualified rate and assembly efficiency of product assembly.

[0005] The present invention solves the above problems through the following technical means:

[0006] A microstrip integrated positioning device for a radio frequency connector, characterized in that it includes a base, a positioning mandrel, a flange positioning slider and a microstrip positioning slider, wherein: a relief groove for positioning the radio frequency connector is provided at the top of the base, and a plurality of first positioning chutes are symmetrically provided on the vertical walls on both sides of the relief groove.

A second slider 402 is provided at the bottom of the microstrip positioning plate 401, and the second slider 402 is movably installed in the second positioning chute 302.

[0029] In this embodiment, the main body of the positioning mandrel 2 is a telescopic rod 201.
