[0036] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0037] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0038] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0039] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0040] An embodiment of this utility model provides a female terminal for mating and plugging into a male terminal, comprising at least three stacked bases 1, with two adjacent bases 1 fixedly assembled and having a plug-in cavity 14 between them. Each plug-in cavity 14 has two openings, a first opening 141 and a second opening 142, with their opening directions at a predetermined angle. A conductive spring 13 for conductive connection with the male terminal is provided on the opposite surface of the base 1 inside the plug-in cavity 14.

[0041] like Figures 1-3 As shown in the figure, as an example, in this embodiment, four female terminal bases 1 are stacked on top of each other, including two first bases 11 and two second bases 12, forming a total of three insertion cavities 14. The first opening 141 and the second opening 142 of each insertion cavity 14 have opposite opening directions, that is, the square opening directions of the first opening 141 and the second opening 142 are 180° apart. In addition, on the two bases on the upper and lower sides, i.e., the first bases 11, only the surface facing the adjacent base, i.e., the second bases 12, are provided with conductive springs 13. On the two bases in the middle, i.e., the second bases 12, conductive springs 13 are provided on both the upper and lower surfaces. The conductive springs 13 are provided with conductive claws at the first opening 141 and the second opening 142.

[0042] Obviously, in other embodiments, by adding or removing the intermediate substrate, i.e., the second substrate, female terminals that can be stacked to accommodate other larger or smaller currents can be formed.

[0043] The aforementioned female terminal includes multiple stacked and fixedly assembled bases 1, thus possessing good assemblability and component compatibility. It can be assembled and disassembled according to actual needs to be suitable for transmitting different currents, saving design, processing and other production costs, and conforming to the technical path of cost reduction and efficiency improvement.

[0044] Furthermore, to make the fixed assembly between the base bodies 1 more convenient and reliable, while also protecting the base bodies 1 and increasing the installability of the base bodies 1 within the connector, such as... Figures 4-7As shown, in this embodiment, the female terminal also includes a housing 3, and the housing 3 is provided with a mounting cavity 31. The base 1 is housed in the mounting cavity 31 and is fixedly connected to the inner wall of the mounting cavity 31 to realize the fixed assembly of two adjacent bases 1. The mounting cavity 31 is provided with a first clearance opening 35 and a second clearance opening 36 at the positions corresponding to the first opening 141 and the second opening 142, respectively.

[0045] Furthermore, in order to achieve a fixed connection between the base 1 and the inner wall of the mounting cavity 31, and to improve connection efficiency and enhance connection effect, such as Figures 4-7 As shown, in this embodiment, the inner walls of the mounting cavity 31 on both sides are provided with positioning grooves 32 extending from the second clearance opening 36. The two opposite sides of the base 1 are inserted into the corresponding positioning grooves 32 from the clearance opening. Furthermore, at least one of the two opposite sides of the base 1 is provided with a rear stop structure and a front stop structure in the insertion direction between it and the corresponding positioning groove 32. As a more preferred structure, in this embodiment, both opposite sides of the base 1 are provided with a rear stop structure and a front stop structure between them and the corresponding positioning groove 32.

[0046] Specifically, considering manufacturability and structural rationality, such as Figures 1-7 As shown, in this embodiment, the corresponding side of the base 1, i.e., the two opposite sides of the base 1, are provided with barbs 21 extending rearward in the insertion direction. The bottom of the corresponding positioning groove 32 is provided with a groove 33 that engages with the barbs 21. The barbs 21 and the groove 33 that engage with each other constitute the rear stop structure. The corresponding side of the base 1, i.e., the two opposite sides of the base 1, are provided with movable stops 22. The bottom of the corresponding positioning groove 32 is provided with fixed stops 34. In the insertion direction, the movable stops 22 and fixed stops 34 on the same side interfere with each other and constitute the front stop structure.

[0047] To facilitate the installation of the barbs 21 and the movable stop 22, and to facilitate the insertion and mating with the positioning slot 32, such as Figures 1-7 As shown, in this embodiment, positioning parts 2 that bend toward the adjacent base 1 are provided on both opposite sides of the base 1. The positioning parts 2 are inserted into the corresponding positioning grooves 32, and barbs 21 and moving blocks 22 are provided on the corresponding positioning parts 2.

[0048] Considering insulation performance, structural strength and conductivity, the outer shell 3 is made of insulating material, such as plastic, the base 1 is made of iron / iron alloy, and the conductive spring 13 is made of copper / copper alloy. In practice, the appropriate material can be flexibly selected according to the design requirements.

[0049] Furthermore, to facilitate the insertion of the male terminal and provide a touch-proof function, at least the first clearance opening 35 is provided with a partition 37 fixedly connected to the housing 3 to separate adjacent first openings 141. Figures 4-7 and Figures 9-10As shown, in this embodiment, the female terminal is first inserted into the second male terminal 5 to form an assembly, and then the assembly is inserted into the first male terminal 4. Thus, the partition 37 can be provided only in the first clearance opening 35 corresponding to the first male terminal 4. At this time, the partition 37 has the function of further positioning the base 1 when the base 1 is still installed in the mounting cavity 31.

[0050] Of course, in other embodiments, it is understood and implemented by those skilled in the art that, as an enhancement, it is also permissible to provide a partition in the second clearance opening corresponding to the second male terminal. However, in this case, the partition in the second clearance opening needs to be fixed to the position of the corresponding base in the second clearance opening by welding or bonding after the base is installed, so as to avoid hindering the installation of the base. Furthermore, the width of the partition at the connection point with the second clearance opening needs to be appropriately reduced to avoid interference with the plastic body on the outside of the second male terminal.

[0051] Furthermore, in order to effectively fix the conductive spring 13, such as Figure 2 , 3 As shown, in this embodiment, the conductive spring 13 is riveted to the corresponding surface of the base 1, and the side of the base 1 is provided with a folded portion 23. After the folded portion 23 folds towards the conductive spring 13, it clamps and fixes the conductive spring 13 together with the corresponding surface of the base 1.

[0052] Embodiments of this utility model also relate to a conductive component, which includes a first male terminal 4, a second male terminal 5, and a female terminal as described above. One end of both the first male terminal 4 and the second male terminal 5 extends to form at least two independent insertion portions 61. The at least two insertion portions 61 of the first male terminal 4 are respectively inserted into corresponding insertion cavities 14 through at least two first openings 141 and are conductively connected to corresponding conductive springs 13. The at least two insertion portions 61 of the second male terminal 5 are respectively inserted into corresponding insertion cavities 14 through at least two second openings 142 and are conductively connected to corresponding conductive springs 13, thereby achieving a conductive connection between the first male terminal 4 and the second male terminal 5. Figures 8-10 As shown, in the conductive component of this embodiment, the first male terminal 4 and the second male terminal 5 have the same structure. Both have three insertion parts 61, and both are formed by welding three male terminal bases 6.

[0053] Furthermore, to achieve the anti-touch function, the first male terminal 4 and the second male terminal 5 are provided with an anti-touch structure at least at the top of the plug portion 61. For example... Figures 8-10 As shown, in this embodiment, the edges of the first male terminal 4 and the second male terminal 5 are both covered with plastic body 7, and the plastic body 7 constitutes the above-mentioned anti-touch structure.

[0054] Obviously, in other embodiments, when the number of female terminal bases changes, resulting in a change in the number of insertion cavities, the corresponding insertion portions of the first male terminal and the second male terminal are adapted and changed, and the two are respectively formed by welding the corresponding number of male terminal bases.

[0055] During the actual assembly, after determining the size of the outer shell 3 according to the actual needs, select the corresponding number of bases 1 to be installed, and then insert the bases 1 one by one into the corresponding positioning slots 32 until the rear stop structure and the front stop structure are correctly matched. At this time, the assembly of the female terminal is completed. Then, the second male terminal 5 is inserted into the female terminal. At this time, the first male terminal 4 can be inserted into the female terminal to complete the assembly of the conductive components.

[0056] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
