To solve this problem, this application discloses a current probe test head and a high-current probe that prevent excessive indentation of the battery terminals. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model discloses a current probe test head and a high current probe to prevent excessive indentation of the electrode post.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a current probe test head for preventing excessive indentation of the electrode post, comprising a test head body, wherein the bottom surface of the test head body is integrally machined with several rows of tooth tips, and the pointed surfaces of multiple tooth tips in the several rows of tooth tips are opened into a planar structure.

[0006] A further preferred embodiment is that the tooth tips are formed into planar structures and distributed around the periphery of several rows of tooth tips.

[0007] More preferably, a through cavity is provided on the upper part of the test head body, and the inner sidewall of the through cavity is formed with a step for cooperating with the current needle.

[0008] More preferably, the bottom surface of the test head has a through groove at its center for the voltage needle test head to pass through.

[0009] A high-current probe, comprising a current needle test probe as described in any of the above.

[0010] This utility model achieves the following beneficial effects:

[0011] This application avoids deep indentations caused by the battery terminals being pierced by planar structures on some of the teeth of the current test head, thus meeting customer needs and having high practical value.

[0012] Other features and advantages of this invention will be set forth in the following description and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained through the structures pointed out in the description and the accompanying drawings. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] Example

[0022] To address the shortcoming of existing high-current probes that cause deep indentations to the battery terminals during use, thus failing to meet user requirements, reference is made to... Figures 1-4As shown, this application discloses a current probe test head for preventing excessively deep indentation of battery terminals, including a test head body 10. The bottom surface of the test head body 10 is integrally machined with several rows of tooth tips 13. Among the several rows of tooth tips 13, the pointed surfaces of multiple tooth tips 13 are formed into planar structures 131. Based on these planar structures 131, when the test head body 10 is used on a high-current probe (other structures of high-current probes besides the test head body structure of this application are known technologies and will not be described in detail here), the battery terminals will not be pierced with deep indentations, thus meeting the user's usage needs.

[0023] In one embodiment, multiple tooth tips 13 with planar surfaces 131 are distributed around several rows of tooth tips 13. In actual use, the tooth tips 13 of other tooth tips 13 can also be planar surfaces 131 as needed.

[0024] In addition to the above structure, the test head body 10 of this application has a through cavity 11 on the upper part of its interior. The inner sidewall of the through cavity 11 has a step 111 for cooperating with the current needle. The bottom center of the test head body 10 has a through groove 12 for the voltage needle test head to pass through. Based on the above structure, the current needle and voltage needle can be installed.
