[0037] Embodiment one

[0038] In view of the defects in the prior art, the present applicant, based on years of rich practical experience and professional knowledge in this field, and with the use of academic theories, actively researched and innovated to create a technology that can solve the defects in the prior art. After continuous research, design, and repeated trial of samples and improvement, the present utility model with practical value was finally created.

[0039] Please refer to Figures 1-3 The embodiment of the present utility model provides a kind of multi-point disposable measurement open circuit voltage tool, which is mainly composed of two core parts of aviation plug male end assembly 1 and voltage measuring device 2. Specifically speaking:

[0040] The aviation plug male end assembly 1 is carefully configured with five pins 3, and each pin 3 is accurately and accurately connected to a specific measurement point in the battery pack through an independent wire 4, thereby realizing the accurate access to five measurement points (such as 1# to 5# measurement points in the battery pack. Figure 1

[0041] The voltage measuring device 2 is equipped with an aviation plug female end 5 matched with the aviation plug male end assembly 1, ensuring stable and reliable connection between the two.

[0042] The design of the aviation plug male end assembly 1 aims to efficiently collect voltage information between any two measurement points in the battery pack (i.e. any one measurement point pair combination, a total of ten measurement point pair combinations, as shown in the figure). Figure 3

[0043] The voltage measuring device 2 is responsible for simultaneously displaying all the voltage information collected by the aviation plug male end assembly 1, providing intuitive and comprehensive measurement data for the operator.

[0044] ​​By means of the ingenious design of the aviation plug male end assembly 1, each pin 3 thereof can be independently and accurately connected with a measuring point in the battery pack through a wire 4 and further connected with the voltage measuring device 2, and the embodiment of the utility model can complete the voltage measurement of ten different measuring point pairs at one time. This innovative design not only significantly reduces the time required for measurement, greatly improves the work efficiency, but also effectively reduces the burden of the operator and reduces the dependence on manual operation, thereby further reducing the measurement error caused by human factors, ensuring the accuracy and high reliability of the measurement results.

[0045] In one embodiment of the embodiment, the aviation plug female head 5 on the voltage measuring device 2 is carefully designed with a plug hole corresponding to the pin 3 in the aviation plug male head 1. These plug holes not only match the number of pins 3, ensuring that each pin 3 can find a corresponding plug hole for connection, but also are accurately adapted in size and shape to ensure that the pin 3 and the plug hole can be tightly and stably connected. Such design not only improves the reliability of the connection and avoids measurement errors caused by poor contact, but also makes the entire connection process smoother and faster, further improving the efficiency and accuracy of the measurement.

[0046] Through this optimization in detail, the embodiment of the utility model realizes more excellent performance and user experience in the design of the multi-point open-circuit voltage measurement tool.

[0047] In one detailed embodiment of the embodiment, the voltage measuring device 2 is embodied as a multimeter or a voltmeter, both of which have the ability to measure voltage with high precision and can meet the demand for accurate measurement of voltage between multiple measuring points in the battery pack.

[0048] Especially worth mentioning is that as a preferred form of the voltmeter, the LED micro-voltmeter has become an extremely attractive choice in this embodiment due to its small size, clear digital display and low power consumption. The LED micro-voltmeter can not only display the measurement results in real time and intuitively, so that the operator can quickly obtain the required information, but also its portability and durability greatly enhance the practicality and flexibility of the entire tool system.

[0049] By using high-quality voltage measuring devices such as multimeters or LED micro-voltmeters, the embodiment not only ensures measurement accuracy, but also fully considers the convenience of operation and the actual use needs of users, thereby further improving the overall performance and user experience of the multi-point open-circuit voltage measurement tool.

[0050] In one embodiment of the present embodiment, the aviation plug male head 1 is innovatively designed with a key feature of a foolproof convex part 5. The purpose of the foolproof convex part 5 is to prevent the occurrence of errors such as incorrect insertion or wrong insertion due to improper operation or negligence, to ensure that each pin 3 is inserted into the correct socket, and to facilitate the voltage measurement device 2 to select the correct measurement point to measure the voltage of the combination, thereby greatly improving the accuracy and safety of the entire connection process.

[0051] This design detail not only reflects the in-depth consideration of user experience, but also highlights the equal emphasis on operational convenience and safety in addition to the pursuit of high-precision measurement. Through the ingenious use of the foolproof convex part 5, the operator can correctly match and connect the aviation plug male head 1 with the aviation plug female head on the voltage measurement device 2 without complex judgment or additional assistance, thereby effectively avoiding measurement errors or equipment damage caused by misoperation.

[0052] In summary, by introducing the innovative design of the foolproof convex part 5, the present embodiment not only further enhances the reliability and practicality of the multi-point one-time open-circuit voltage measurement tool, but also provides more convenient and safe operation experience for the operator.

[0053] In a more detailed and comprehensive embodiment of the present embodiment, the aviation plug male head 1 is endowed with a more advanced foolproof design, i.e., two foolproof convex parts 5 are provided. These two foolproof convex parts 5 not only exhibit symmetrical distribution in position, but also are designed differently in size, i.e., their sizes are different.

[0054] Such a double foolproof mechanism undoubtedly provides more solid protection for the entire connection process. First, the symmetrical distribution of the foolproof convex parts 5 allows the plug to be restricted from two directions when inserted, effectively preventing the possibility of incorrect insertion. Second, the different sizes further enhance the foolproof effect, so that even if the operator experiences a brief visual confusion or judgment error, they can quickly realize and correct the mistake, thereby avoiding measurement errors or equipment damage caused by misoperation.

[0055] Through this innovative and thoughtful design, the present embodiment not only greatly improves the reliability and safety of the multi-point one-time open-circuit voltage measurement tool, but also provides more convenient and efficient operation experience for the operator. This design undoubtedly is another important innovation to the traditional foolproof mechanism, setting a new benchmark for the battery pack voltage measurement field.

[0056] Although the aviation plug male head, voltage measuring device and other terms are used more in the present application, the possibility of using other terms is not excluded. The use of these terms is only to facilitate the description and explanation of the essence of the utility model; any additional limitation by interpreting them is contrary to the spirit of the utility model.

[0057] The utility model provides a kind of multi-point disposable measurement open-circuit voltage tool, by setting aviation plug male head, and design the each pin of aviation plug male head is respectively connected with the measuring point of battery pack by a wire, and design aviation plug male head and voltage measuring device connection, so that ten different measuring points can be measured simultaneously to combination, not only save the time of measurement, improve work efficiency, also reduce the dependence on operator, to reduce the measurement error caused by human factor, can ensure the accuracy of measurement result.

[0058] Finally, it needs to be explained that, although the above-mentioned embodiments have been described in the specification and drawings of the present application, it does not limit the patent protection scope of the present application. Any technical solution obtained by replacing or modifying the equivalent structure or equivalent process based on the essential concept of the present application, using the content described in the specification and drawings, and directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, etc. are all included in the patent protection scope of the present application.
