The test probe structure that a kind of inclined-plane is surveyed
[technical field]
The utility model relates to the test probe technical field, and in particular, the utility model relates to the test probe structure that a kind of inclined-plane is surveyed.
[background technology]
In the component testing technical field, often need to carry out with test probe the test of various parameters to components and parts.Existing test probe 10 mostly is vertical plane, shown in Fig. 1, it while contacting with element 20, is the face contact, the deviation of position due to the difference of element 20 pins and while surveying, test probe 10 being contacted with element 20 pins and be than the contact of larger area face sometimes, be the face contact of small size sometimes, may be also line contact or some contact sometimes, so just there are the factors of instability, affect measuring accuracy.In addition, while when the test probe 10 on both sides is different, touching element, also can make element float or an end sticks up, so also make test result inaccurate.
[utility model content]
The purpose of this utility model is effectively to overcome the deficiency of above-mentioned technology, the test probe structure that provides a kind of inclined-plane that improves measuring accuracy to survey, when this probe structure is the testing element contact, can prevent that testing element from floating or being upturned, improve the precision of test.
The technical solution of the utility model is achieved in that it includes two probe sets, its improvements are: in described two probe sets, be fixed with respectively a test probe, two test probes are oppositely arranged, the top of described two test probes all has an inclined-plane, the angle of this inclined-plane and surface level is less than 90 °, and described two test probes can clamp testing element tested;
In above-mentioned structure, described test probe also has end face and bottom surface, and the angle on described end face and inclined-plane is A, and the angle on described bottom surface and inclined-plane is B, wherein, described included angle A<90 °, included angle B > 90 °;
In above-mentioned structure, described included angle A=80 °, described included angle B=100 °.
The beneficial effects of the utility model are: the utility model arranges an inclined-plane by the top at test probe, the angle of this inclined-plane and surface level is less than 90 °, the design of this kind of structure, can guarantee that test probe is the line contact while contacting with testing element, there are not the factors of instability, improved greatly measuring accuracy, simultaneously, design due to this kind of inclined-plane, when test probe contacts with testing element, test probe can produce a downward component to testing element, one end that can prevent testing element floats or perk, improve measuring accuracy, the utility model is by the design of simple structure, can increase the cost of product hardly, make the raising that measuring accuracy is very large.

Fig. 1 is test probe structure of the prior art;
Fig. 2 is front view of the present utility model;
The partial enlarged drawing that Fig. 3 is C place in Fig. 2.
[embodiment]
Below in conjunction with drawings and Examples, the utility model will be further described.
Shown in Fig. 2, the utility model has disclosed the test probe structure that a kind of inclined-plane is surveyed, this test probe structure includes two probe sets 30, and two probe sets 30 are symmetrical arranged, interior test probe 40, two test probes 40 that are fixed with respectively of two probe sets 30 are oppositely arranged, shown in Fig. 3, the top of two test probes 40 all has a 401,Gai inclined-plane, inclined-plane 401 and is less than 90 ° with the angle of surface level, and two test probes 40 can clamp testing element 50 tested.In the present embodiment, test probe 40 has end face 402 and bottom surface 403, and end face 402 is A with the angle on inclined-plane 401, and the angle on 403Yu inclined-plane, bottom surface 401 is B, wherein, described included angle A<90 °, included angle B > 90 °, preferably, described included angle A=80 °, described included angle B=100 °.
The utility model is by the design of said structure, when testing element 50 is tested, can guarantee that test probe 40 is the line contact while contacting with testing element 50, there are not the factors of instability, improved greatly measuring accuracy, simultaneously, design due to this kind of inclined-plane 401, when test probe 40 contacts with testing element 50, test probe 40 can produce a downward component to testing element 50, one end that can prevent testing element 50 floats or perk, improve measuring accuracy, the utility model is by the design of simple structure, can increase the cost of product hardly, make the raising that measuring accuracy is very large.
Described above is only preferred embodiment of the present utility model, and above-mentioned specific embodiment is not to restriction of the present utility model.In technological thought category of the present utility model, various distortion and modification can appear, the retouching that all those of ordinary skill in the art make according to above description, revise or be equal to replacement, all belong to the scope that the utility model is protected.
