Description

Technical Field

[0001] The invention relates to the field of ESD test reliability test verification, in particular to a fixed conversion device for ESD test. Background Art

[0002] At present, different circuits usually need different fixtures to complete the electrostatic discharge sensitivity (ESD) test, which often leads to the situation that the circuit fixture does not match the equipment or the thick film circuit has no fixture, such as the difficulty of processing and clamping the working surface of the converter and the high processing cost. The common solution is to remake the fixture, but this method is costly, time-consuming, and inefficient, and the produced fixture is usually only suitable for this type of circuit and has poor versatility. Summary of the invention

[0003] The present invention aims to overcome the deficiencies in the prior art and to provide a fixed conversion device for ESD testing that is safe, efficient and universal.

[0004] This application provides the following technical solutions: A fixed conversion device for ESD testing, characterized in that it includes a conversion board, on which is disposed a group of pins and a plurality of groups of spiral connectors, on each of which a connector is detachably connected, the connector including a connector corresponding to the spiral connector, on which a connecting wire and a connecting sleeve are sequentially disposed, and on which a locking pin is disposed.

[0005] On the basis of the above technical solutions, there are also the following further technical solutions: The group of pin headers and the group of spiral connectors are arranged on different surfaces of the conversion plate.

[0006] The group of pins and the plurality of groups of spiral connectors are distributed along the width direction of the conversion plate, and one group of pins is distributed between two groups of spiral connectors.

[0007] The conversion board is a PCD board.

[0008] Advantages of the invention: The invention has a simple structure and is easy to use, making the ESD test process safe, efficient and universal. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a three-dimensional structural schematic diagram of the present invention; Figure 2 It is a schematic diagram of the structure in another direction; Figure 3 yes Figure 2 A-axis enlarged view. DETAILED DESCRIPTION

[0010] like Figure 1-3 As shown, a fixed conversion device for ESD test includes a conversion board 2, which is a PCD board. Two rows of pins 3 are connected to the upper surface of the conversion board 2 and distributed along the width of the conversion board 2.

[0011] A group of spiral connectors 4 are installed on the lower surface of the conversion plate 2 on both sides of the pin header 3 and are arranged in a straight line along the width direction of the conversion plate 2. A connector 5 is detachably connected to each spiral connector 4. The connector 5 includes a connector 5a corresponding to the external thread section on the spiral connector 4. The connector 5a is provided with a connecting wire 5b and a connecting sleeve 5c in sequence, and a locking pin 5d is provided on the connecting sleeve 5c. The connecting wire 5b has a certain flexibility, so that it can be deformed under the bending of the user according to the needs of the operation, so that it can be conveniently connected to its corresponding test circuit pin or fixture pin header.

[0012] Working process: When in use, insert the pin header 3 into the ESD test equipment (ESD electrostatic discharge sensitivity tester) and then connect the connector 5 with the screw connector 4. Then insert the pins of the circuit that needs to be tested for ESD or the pin header of the effective fixture connected to the circuit into the connecting sleeve and lock it with the locking pin. This forms an electrical connection between the circuit to be tested and the ESD test equipment.
