[0033] As shown in the accompanying drawings, Figure 1 The assembled battery tab assembly provided by the utility model comprises a base 100 and a functional part 200 connected in two parts. At least two installation grooves 110 are formed in the base 100, the installation grooves 110 are used for installing the functional part 200, and the number of the installation grooves 110 is greater than or equal to the number of tab connection slots on the battery. In combination with the accompanying drawings, Figure 2 The functional part 200 comprises a support 210 and a metal tab 220. The metal tab 220 is fixedly connected to the support 210, and both ends of the metal tab 220 in the third direction pass through the support 210 and are used for connecting the battery and the load. The number of the installation grooves 110 corresponds to the number of the tab connection slots on the battery. One end of the metal tab 220 is inserted into the tab connection slot, and the support 210 is installed in the installation groove 110.

[0034] The base 100 and functional unit 200 are designed to be connected separately. Mounting slots 110, matching the number of insert connection slots, are provided on the base 100 to accommodate the installation of the functional unit 200. When the number of mounting slots 110 is the same as the number of insert connection slots, an appropriate number of mounting slots 110 can be selected based on battery connection requirements. When the number of mounting slots 110 is greater than the number of insert connection slots, an appropriate number of functional units 200 can be installed based on battery connection requirements. This design offers high flexibility, allowing the functional units 200 to be assembled according to actual needs. During manufacturing, the base 100 and functional unit 200 can be processed separately. When compatible with a battery, the corresponding number of functional units 200 can be installed on the base 100 according to the battery specifications. This design facilitates assembly, saves processing costs, and provides excellent adaptability.

[0035] For example, the metal insert 220 and the bracket 210 are integrally formed by injection molding. The metal insert 220 is placed in the mold, and the bracket 210 is then processed by injection molding, so that the metal insert 220 and the bracket 210 can be connected. The processing is simple and convenient, and the processing cost is low.

[0036] For example, the metal insert 220 is at least one or a combination of steel, copper and aluminum.

[0037] In one example, the bracket 210 is provided with a fixing part for mounting the bracket 210 to the base 100. More specifically, the bracket 210 is mounted in the mounting groove 110 by means of the fixing part.

[0038] As attached Figure 2 As shown, the fixing part includes a limiting member 211 and a snap-fit ​​member 212. The limiting member 211 and the snap-fit ​​member 212 protrude from both ends of the bracket 210 in the first direction and extend protrudingly along the first direction. The limiting member 211 and the snap-fit ​​member 212 are spaced apart along the third direction. A slot 213 is provided between the limiting member 211 and the snap-fit ​​member 212. Figure 1 and attached Figure 3 The mounting groove 110 is provided with a stop 120, which protrudes from the two sides of the mounting groove 110 in the first direction and extends protrudingly in the first direction. When the functional part 200 is installed on the base 100, the bracket 210 is accommodated in the mounting groove 110 and the stop 120 is accommodated in the slot 213. The lower end of the limiting member 211 contacts the upper end of the stop 120. Through the cooperation of the limiting member 211 and the snap-fit ​​member 212, the bracket 210 can be prevented from coming out of the mounting groove 110. The installation is convenient and quick, and has a good fixing effect.

[0039] For example, as shown in the appendix Figure 3 As shown, the lower end face of the stop 120 is flush with the lower end face of the base 100.

[0040] For example, as shown in the appendixFigure 3 As shown, when the bracket 210 is installed in the installation slot 110, the upper end surface of the limiting piece 211 is flush with the upper end surface of the base 100.

[0041] Exemplarily, the length dimension of the limiting piece 211 in the first direction is greater than the length dimension of the clamping piece 212 in the first direction, so that the clamping piece 212 is easily moved downward below the stop piece 120 relative to the stop piece 120, and the limiting piece 211 cooperates with the stop piece 120 to prevent the bracket 210 from being pulled out of the installation slot 110.

[0042] Exemplarily, the limiting piece 211 and the clamping piece 212 are perpendicular to the bracket 210, and the stop piece 120 is perpendicular to the slot wall of the installation slot 110.

[0043] In an example scheme, as shown in FIG. 1, the base 100 is provided with a plurality of functional parts 200, and the functional parts 200 are arranged in the first direction. Figure 2 As shown, the clamping piece 212 is provided with a guide inclined surface 214 away from one end of the bracket 210 in the first direction, and the length dimension of the clamping piece 212 in the first direction gradually decreases from top to bottom, so that in the installation process, the clamping piece 212 is in contact with the stop piece 120 through the guide inclined surface 214 and is easily moved downward relative to the stop piece 120, and the stop piece 120 is easily entered into the installation slot 110, so as to realize the quick installation of the functional part 200 and the base 100, and improve the installation efficiency.

[0044] Exemplarily, the limiting piece 211, the clamping piece 212 and the bracket 210 are integrally formed.

[0045] Based on the above-mentioned assembled battery plug assembly, the utility model further provides a battery, which comprises at least two plug connection slots, the plug connection slots are used for being connected with metal plugs 220 to realize the electrical connection of the load and the battery, or the electrical connection and the communication connection, the base 100 of the above-mentioned assembled battery plug assembly is used for being connected with the battery, the base 100 is provided with the same number of functional parts 200 as the plug connection slots, and when the above-mentioned assembled battery plug assembly is connected with the battery, the metal plug 220 is accommodated in the plug connection slot.

[0046] In an example scheme, when the load and the battery only realize the electrical connection function, only two plug connection slots are arranged on the battery, as shown in FIG. 2, and the base 100 is connected with two functional parts 200 to cooperate with the plug connection slots on the battery to realize the positive and negative electrode connection. Figure 1

[0047] In another example scheme, when the load and the battery need to realize the electrical connection and the communication connection function, three or four plug connection slots are arranged on the battery, combined with FIG. 3 and FIG. 4. Figure 4 Figure 5 ​​The base 100 is provided with three or four installation grooves 110 for installing the functional part 200 to cooperate with the plug piece connection groove on the battery, two functional parts 200 are used to realize the positive and negative pole connection with the battery, and the other one or two functional parts 200 are used to realize the communication connection with the battery, such as realizing the temperature detection, the over-temperature protection, the over-current protection, the battery legality identification and the like.

[0048] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
