Description
Technical Field
The utility model relates to the technical field of test fixtures, in particular to a probe separation type test fixture.
Background
At present, a test probe of a test fixture needs to be connected to corresponding test equipment through a manual welding wire, and the welded test probe is equivalent to disposable. When the test fixture needs to be replaced, wires need to be removed and welded again, if the test needle base has a plurality of needles, a great deal of time and energy are needed to manually weld the needles by using an electric iron, the test efficiency is low, the problems are not easy to find out, and the universality is not high.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a probe separation type test fixture, which divides a test needle into two detachable parts, improves the test efficiency and the universality and is convenient to maintain.
The utility model discloses a probe separation type test fixture, which adopts the technical scheme that:
the utility model provides a probe disconnect-type test fixture, includes the testboard, the testboard is equipped with the test board, be equipped with the test needle on the test board, the test needle is including being fixed in the test connection portion on the test board to and the equipment connecting portion of being connected of can dismantling the electricity with the test connection portion, the equipment connecting portion are used for the electricity to connect external test equipment.
Preferably, the test connection part is rod-shaped, the device connection part is tubular, and the test connection part is inserted into the device connection part.
As the preferred scheme, the side edge of the test connecting part is provided with a limiting bulge.
The probe separation type test fixture disclosed by the utility model has the beneficial effects that: the test needle includes test connecting portion and the equipment connecting portion two parts of can dismantling the electricity and connecting, and when needs tested, outside test equipment passes through the line and is connected with the equipment connecting portion electricity, then installs the equipment connecting portion in test connecting portion, then is connected with being tested the equipment electricity through test connecting portion. When the test fixture needs to be replaced, the equipment connecting part is only required to be taken out of the test connecting part and reinstalled on the test connecting part of the replaced test fixture, and then the test can be carried out. After the scheme divides the test needle into two detachable parts, when the test fixture is replaced, the wiring does not need to be detached again, so that the test efficiency and the universality are improved, and the maintenance is convenient.
Drawings
FIG. 1 is a schematic structural diagram of a probe-separated test fixture according to the present invention.
FIG. 2 is a schematic view of a testing probe structure of the probe-separating testing fixture of the present invention.
Detailed Description
The utility model will be further elucidated and described with reference to the embodiments and drawings of the specification:
referring to fig. 1 and 2, the prober includes a testing table 10, the testing table 10 has a testing board 20, and the testing board 20 has testing needles 30. The test pin 30 includes a test connection portion 32 fixed on the test board 20, and a device connection portion 34 detachably and electrically connected to the test connection portion 32, wherein the device connection portion 34 is used for electrically connecting an external test device.
The test pin 30 includes two parts, namely a test connection part 32 and a device connection part 34 which are detachably and electrically connected, when a test is required, external test equipment is electrically connected with the device connection part 34 through a wire, then the device connection part 34 is installed on the test connection part 32, and then the device is electrically connected with the tested equipment through the test connection part 32. When the test fixture needs to be replaced, the test can be performed only by taking the equipment connecting part 34 out of the test connecting part 32 and reinstalling the equipment connecting part on the test connecting part 32 of the replaced test fixture. After the test needle 30 is divided into the two detachable parts, the wiring does not need to be detached again when the test fixture is replaced, so that the test efficiency and the universality are improved, and the maintenance is convenient.
In this embodiment, the test connection portion 32 is rod-shaped, the device connection portion 34 is tubular, and the test connection portion 32 is inserted into the device connection portion 34. Specifically, the test connection portion 32 of the test pin 30 is fixed on the test board 20 for electrical connection with the device under test, and has a cylindrical rod shape. And the device connecting portion 34 of the test pin 30, which is used for electrical connection with the test device, has a hollow cylindrical tubular shape. The test connection portion 32 is plugged into the device connection portion 34, and the test connection portion 32 and the device connection portion 34 are in one of interference fit, transition fit and clearance fit. The test connection 32 and the device connection 34 are made of conductive materials, and the mounting positions of the test connection 32 and the device connection 34 can be changed.
In other embodiments, the test connection portion 32 and the device connection portion 34 may be detachably and electrically connected through other methods, for example, the test connection portion 32 is provided with an external thread, the device connection portion 34 is provided with an internal thread, and then the threaded connection is performed, for example, a clamping groove is formed in the side edge of the test connection portion 32, and a matching clamping block is arranged on the inner side of the device connection portion 34, and then the clamping connection is performed.
Further, a limit protrusion 322 is disposed on a side of the test connection portion 32. Specifically, the limiting protrusion 322 is a protruding ring at the side of the test connection part 32, and is used for limiting the test connection part 32 when being inserted into the device connection part 34.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the protection scope of the present invention, although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
