Description
Technical Field
The utility model relates to a fan wiring detection area especially relates to a fan test termination.
Background
At present, the detection of fan wiring is mostly completed by assembling a single test pin on an insulating plate, and a plurality of test pins are fixed on the insulating plate through a base to test elements independently.
As disclosed in chinese utility model patent publication No. CN206020481U, an assembled test pin is disclosed, comprising a base and a plurality of test pins, wherein the base is provided with a plurality of mounting through holes, and each mounting through hole is internally provided with a test pin; the test needle comprises a needle rod, a spring is arranged on the needle rod, a test head is arranged at the end part of the needle rod, and the spring is arranged between the pillow and the needle tube.
The test needle has the advantages of simple structure and easy assembly and disassembly, however, the length of the spring needs to be matched with the distance between the needle head and the needle sleeve, the too long causes the overlarge moving space of the head part of the test needle, the too short causes the larger thrust of the spring to the needle head, and the tested element is possibly damaged, so the requirement on the processing precision is higher. In addition, although the spring can play a role in buffering, when the test is completed, the spring still has a certain thrust on the needle head, and if the tester does not pay attention to the needle head, the needle head or the tested element is easily damaged.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims at providing a simple structure, the machining precision requirement is lower, and protects the fan wiring testing arrangement of test needle and tested product to a certain extent, and above-mentioned technical purpose is realized through following technical scheme:
the utility model provides a fan wiring testing arrangement, places the piece including the test needle, the test needle is placed a plurality of mounting holes of having seted up in parallel in the piece, all is provided with the test needle in each mounting hole, and the test needle can slide its characterized in that in the mounting hole: the testing device is characterized by also comprising a spring, wherein one end of the spring is fixedly arranged in the mounting hole, and part of the spring is exposed out of the testing needle placing block; the outer surface of the testing needle is sleeved with the spring, and the other end of the spring is fixedly connected with the testing needle.
Further: and a handle is fixedly arranged on the test needle placing block.
Preferably: the handle is parallel to the testing needle and arranged towards the opposite direction of the head of the testing needle.
Further: the head of the test needle is provided with a convex edge for limiting the spring.
The utility model has the advantages that: the spring is fixedly arranged in the mounting hole, a limiting device is not required to be arranged, the structure is simple, the length and the size of the spring are not required to be limited, and the processing is convenient; the friction force between the spring and the mounting hole can play a certain buffering role, and the resilience force of the spring is reduced when the test is finished, so that the original piece to be tested and the needle head are not easily damaged; set up the chimb and guarantee test needle and spring coupling's stability on the one hand, on the other hand has injectd the test needle displacement volume, and the spring resilience force can not be too big when guaranteeing to finish the test.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic cross-sectional view of the present invention.
In the figure, 1, a test needle placing block; 2. a test pin; 21. a convex edge; 3. a spring; 4. a handle; 5. the product to be tested.
Detailed Description
The following is further illustrated with reference to the accompanying drawings:
combine fig. 1 and fig. 2 to show, a fan wiring testing arrangement, place piece 1 including the test needle, the test needle is placed a plurality of mounting holes of having seted up in block 1 in parallel, all is provided with test needle 2 in each mounting hole, and test needle 2 can slide its characterized in that in the mounting hole: the testing device is characterized by further comprising a spring 3, wherein one end of the spring 3 is fixedly arranged in the mounting hole, and part of the spring is exposed out of the testing needle placing block 1; the outer surface of the testing needle 2 is sleeved with the spring 3, and the other end of the spring 3 is fixedly connected with the testing needle 2. During testing, the testing needle 2 is contacted with the tested product 5, the testing needle 2 slides in the mounting hole under the action of the reaction force, the spring 3 is pulled by the sliding of the testing needle 2 due to the fixed connection of the testing needle 2 and the spring 3, on one hand, the spring 3 stops the sliding of the testing needle 2, on the other hand, the spring plays a role in buffering, and the action force between the testing needle 2 and the tested product 5 is not too large; when the test is finished, because frictional force exists between the spring 3 and the mounting hole as well as between the test needle 2 and the spring 3, the resilience force of a part of the spring 3 can be counteracted, so that the acting force between the test needle 2 and the tested product 5 can not be too large when the test is finished, and the test needle and the tested product 5 are protected.
In consideration of safety and convenience, the testing needle placing block 1 is also fixedly provided with a handle 4, and the handle 4 is parallel to the testing needle 2 and is arranged towards the opposite direction of the head of the testing needle 2.
As shown in fig. 2, the head of test needle 2 is equipped with the chimb 21 spacing to spring 3 for spacing to test needle 2, when test needle 2 slides, chimb 21 can the butt place the side of piece 1 in the test needle, has guaranteed that the displacement volume of test needle 2 can not be too big, prevents that test needle 2 and the effort of being tested between the product 5 is too big and lead to test needle 2 and the damage of being tested the product 5.
