Example Embodiment

[0025] The following describes in detail the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as a limitation of the present invention.
[0026] In the description of the present invention, if it is described that the first and the second are only for the purpose of distinguishing technical features, it should not be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or implicitly indicating The order of the indicated technical features.
[0027] In the description of the present invention, unless otherwise clearly defined, words such as setting, installation, connection should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meaning of the above words in the present invention in combination with the specific content of the technical solution.
[0028] like figure 1 and figure 2 As shown in the figure, a mirror-cut needle probe of the present invention includes a needle tube 1, an elastic member 2 is arranged in the needle tube 1, and needle heads 3 are respectively inserted at both ends of the needle tube 1, and the tails of the two needle heads 3 are respectively abutted on the At both ends of the elastic member 2, the head of each needle 3 is provided with a plurality of serrations 4 in a claw shape, and the surface of each serration 4 is mirror-polished.
[0029] Different from the existing probe, the needle 3 of the present invention is provided with a plurality of serrations 4, and the plurality of serrations 4 can be adapted to test points of different shapes, so as to ensure that the needle 3 can form a good contact with the test points. In addition, the surfaces of the saw teeth 4 are all mirror-polished, and the roughness is small and relatively smooth. Therefore, the service life of the probe is greatly extended.
[0030] combine figure 2 , In a mirror cutting needle probe of the present invention, the number of saw teeth 4 is four, which are arranged at an equal angle of 90°.
[0031] The four serrations 4 are arranged symmetrically in two pairs, so that the design can increase the contact area and can make contact with test points of different shapes.
[0032] combine figure 2 , in a mirror cutting needle probe of the present invention, the serrations 4 are in the shape of three-sided prisms.
[0033] The serrations 4 are in the shape of three-sided prisms, which are convenient for mirror processing and are more convenient to operate.
[0034] combine figure 2 , in a mirror cutting needle probe of the present invention, the elastic member 2 is a compression spring.
[0035] The two needles 3 are respectively in contact with the testing point and the testing machine. After being squeezed, they are elastically contracted by the elastic member 2, which can ensure good contact and no disconnection.
[0036] like figure 1 As shown, in a mirror-cut needle probe of the present invention, both ends of the needle tube 1 are formed with a constriction, the outer diameter of the tail of the needle 3 is larger than the outer diameter of the head, and the tail of the needle 3 is limited within the constriction.
[0037] By processing the constriction at both ends of the needle tube 1, the tail of the needle head 3 can be limited in the needle tube 1, and the operation is relatively convenient.
[0038] like figure 1 As shown, in a mirror cutting needle probe of the present invention, the tail of the needle 3 is provided with a tapered surface, and the end of the elastic member 2 is sleeved on the tapered surface.
[0039] Such a design can ensure a large contact surface between the elastic member 2 and the tail portion of the needle 3 to form a good contact.
[0040] like figure 1 As shown, a processing method of a mirror-cut needle probe of the present invention is specifically implemented according to the following steps:
[0041] Step 1, mirror cutting the needle 3 to process a plurality of saw teeth 4;
[0042] Step 2, insert a needle 3 from one end of the needle tube 1;
[0043] Step 3, put the compression spring into the needle tube 1;
[0044] Step 4, insert another needle 3 from the other end of the needle tube 1;
[0045] Step 5, encapsulate the two needles 3 in the needle tube 1 .
[0046] like figure 1 As shown, in a processing method of a mirror-cut needle probe of the present invention, in step 1, the number of saw teeth 4 is four, and they are arranged at an equal angle of 90°.
[0047] The four serrations 4 are arranged symmetrically in two pairs, so that the design can increase the contact area and can make contact with test points of different shapes.
[0048] like figure 1 As shown, in the processing method of a mirror-cut needle probe of the present invention, in step 1, the saw teeth 4 are in the shape of three-sided prisms.
[0049] The serrations 4 are in the shape of three-sided prisms, which are convenient for mirror processing and are more convenient to operate.
[0050] like figure 1 As shown, in the processing method of a mirror-cut needle probe of the present invention, in step 5, encapsulating the two needles 3 in the needle tube 1 is specifically: forming a constriction at both ends of the needle tube 3, The tail of 3 is limited in the needle tube 1.
[0051] By processing the constriction at both ends of the needle tube 1, the tail of the needle head 3 can be limited in the needle tube 1, which is convenient for operation and low in cost.
[0052] Therefore, compared with the prior art, the present invention can adapt to more test objects by changing the shape of the traditional probe needle to form a serrated claw head, thereby further expanding the use scene of the probe. In addition, because the surface of the sawtooth is in a mirror state, the roughness is small, the finish is good, the tin removal performance is good, and it is not easy to be stained, so that the test accuracy is high, the service life is greatly improved, and the use cost of the test probe is reduced. .
[0053] The foregoing specification shows and describes several preferred embodiments of the invention, but as previously mentioned, it should be understood that the invention is not limited to the form disclosed herein and should not be construed as an exclusion of other embodiments, but may be used in a variety of other Combinations, modifications and environments are possible within the scope of the inventive concepts described herein, from the above teachings or from skill or knowledge in the relevant fields. However, modifications and changes made by those skilled in the art do not depart from the spirit and scope of the invention, and should fall within the protection scope of the appended claims of the invention.
