Test adapter of small-spacing connection terminal

Abstract

The invention, which belongs to the field of electrical power module testing, relates to a test adapter for a small-spacing connection terminal. The test adapter comprises a main adapter body manufactured by a conductor. The main adapter body is provided with output voltage sampling holes and load connecting holes; a cuboid crimping body is arranged at the front end of the main adapter body. The adapter includes a left negative adapter, a right negative adapter, a right positive adapter, and a left positive adapter, wherein the left negative adapter and the right negative adapter are connectedwith a negative electrode of a direct-current power supply module and the right positive adapter and the left positive adapter are connected with a positive electrode of the direct-current power supply module; a BNC-to-SMA radio-frequency adapter connected with a standard testing line directly is arranged at the left negative adapter or the right negative adapter; and metal planes for convenientcontact and signal collection of a standard probe are arranged at the front parts of the left positive adapter and the right positive adapter. Therefore, problems that one wiring terminal needs to beconnected with a plurality of testing lines and a sampling probe of an oscilloscope can not be connected are solved and thus reliable and rapid access of a measuring instrument becomes convenient; andbecause the sampling point and the measurement method are fixed, the quality of testing data of the measuring system is enhanced. The measurement reproducibility is high.

Description

technical field [0001] The invention belongs to the field of electrical power supply module testing, and relates to a test adapter for measuring output signals of small-pitch terminal blocks. Background technique [0002] The power module is the basis for the work of electronic instruments or equipment. It is of great significance to carefully evaluate the performance of the power module in the application and optimize the power module used in the product to improve the quality, reliability and anti-interference ability of the product under research. [0003] At present, the most common interface types of power modules are Figure 11 The partition type terminal block shown, and some are ON-SHORE technology terminal blocks, the shape is as follows figure 1 shown. For small-pitch bulkhead-type terminal blocks, due to the small spacing between adjacent terminals, another invention "a test adapter for bulkhead-type terminal blocks" cannot be used for switching tests, especial...
