[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1 to 7 , the utility model provides a battery testing probe.

[0027] The battery test probe includes a probe mounting base 100 and a probe assembly 200, the probe mounting base 100; the probe assembly 200 includes a probe rod body 210 and a probe head 220, the probe rod body 210 is inserted into the probe base, and the probe head 220 has a mounting groove 221, the probe rod body 210 is embedded in the mounting groove 221, and the probe head 220 is used to contact the tab of the battery to be tested for detection; a snap portion is provided on the probe rod body 210, and a buckling portion that can cooperate with the snap portion is provided on the probe head 220, and the probe rod body 210 and the probe head 220 are clamped together through the snap portion and the buckling portion; wherein, the material of the probe rod body 210 is beryllium copper, and the material of the probe head 220 is brass.

[0028] Specifically, the connection and fixing method between the snap portion and the buckle portion can be in various forms, and it is only necessary to be able to assemble and fix the probe head 220 and the probe rod body 210 by limiting the mutual cooperation of the mechanical structure. During assembly, the probe head 220 and the probe rod body 210 are tightly fitted and driven in. Through the structural cooperation and limitation between the snap portion and the buckle portion, the assembly and fixation of the probe head 220 and the probe rod body 210 can be achieved, and the connection and fixation between the snap portion and the buckle portion can be ensured. Since the probe rod body 210 and the probe head 220 are formed separately, the probe rod body 210 and the probe head 220 are made of different materials, that is, the material of the probe rod body 210 is beryllium copper, and the material of the probe head 220 is brass. Since the price of brass is lower than that of beryllium copper, compared with the battery test probe made of traditional integral beryllium copper material, the battery test probe of the utility model has a simple processing technology, which greatly reduces the overall material cost and further reduces the production cost of the battery test probe.

[0029] See also Figure 7Preferably, the buckle portion is an annular clamping groove 222 formed by the probe head 220 at the installation groove 221, and the buckle portion is an annular clamping edge 211 protruding from the end of the probe rod body 210, and the annular clamping edge 211 is arranged in the annular clamping groove 222. During assembly, the end of the probe rod body 210 is inserted into the installation groove 221 of the probe head 220. As the probe rod body 210 gradually goes deeper, the annular clamping edge 211 on the probe rod body 210 contacts the bottom of the installation groove 221 of the probe head 220, causing the annular clamping edge 211 on the probe rod body 210 to deform and spread toward the periphery, so that the annular clamping edge 211 can be inserted into the annular clamping groove 222. Through the structural restriction between the annular clamping edge 211 and the annular clamping groove 222, the mortise and tenon structure is utilized to achieve structural stability between the probe rod body 210 and the probe head 220, preventing problems such as loosening and rotation. Of course, the shapes of the annular groove 222 and the annular clamping edge 211 are not limited to this. The clamping edge can also be composed of multiple spaced-apart clamping blocks, which are inserted into the groove to ensure the stability of the assembly between the probe head 220 and the probe rod body 210.

[0030] See also Figures 4 to 7 Preferably, the annular clamping edge 211 has a first position and a second position, and the annular clamping edge 211 can be squeezed and deformed by the probe head 220 to change from the first position to the second position; in the first position, the annular clamping edge 211 stands up on the probe head 220 along the central axis direction of the probe head 220; in the second position, the annular clamping edge 211 is flipped open in a direction away from its center and is clamped into the annular groove. It can be understood that the annular clamping edge 211 can be deformed. Before assembly, the annular clamping edge 211 stands up on the probe head 220 along the central axis direction of the probe rod body 210. At this time, the annular clamping edge 211 is in the first position, which is the initial position before assembly. As the annular clamping edge 211 is gradually installed on the probe rod body 210, the annular clamping edge 211 can be squeezed by the probe rod body 210 and folded toward the periphery. The annular clamping edge 211 is transformed from the first position to the second position, so that the annular clamping edge 211 can be clamped into the annular clamping groove 222, thereby realizing stable installation of the probe rod body 210 and the probe head 220.

[0031] See also Figures 4 and 5 Preferably, the annular clamping edge 211 has a guiding bevel 212, which gradually moves away from the probe shaft body 210 from the center of the annular clamping edge 211 toward a direction away from the center of the annular clamping edge 211. With this arrangement, when the annular clamping edge 211 is inserted into the mounting groove 221 of the probe head 220, the guiding effect of the guiding bevel 212 facilitates the deformation of the annular clamping edge 211, and the annular clamping edge 211 gradually folds toward the outer periphery, allowing the annular clamping edge 211 to be inserted into the annular clamping groove 222, thereby maintaining the stability of the probe head 220 and the probe shaft body 210.

[0032] See also Figure 2 and Figure 6 Preferably, the sidewall of the probe rod body 210 is provided with a plurality of annular grooves along its circumference. Fillers 213 are provided in the annular grooves. Fillers 213 are tin paste or brazing paste. Fillers 213 can be melted by high-frequency heating to fill the assembly gap between the probe rod body 210 and the probe head 220. In this way, the brazing paste is fully melted by high-frequency heating to fill the assembly gap between the probe rod body 210 and the probe head 220, ensuring electrical conductivity. When the probe head 220 contacts the two battery terminals, current can be passed to the probe rod body 210.

[0033] Preferably, the probe head 220 is gold-plated and the probe rod body 210 is nickel-plated. By gold-plating the probe head 220 and nickel-plating the probe rod body 210, surface oxidation or corrosion can be effectively prevented, thereby increasing the service life of the probe assembly 200.

[0034] The above are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made by utilizing the contents of the present invention specification and drawings under the practical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
