[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of them. The embodiments of the basic utility model and all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present utility model.

[0021] according to Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, a continuous stamping type female terminal includes a terminal body 10 formed by rolling and connecting a sheet of sheet structure, and the tail end of the terminal body 10 forms a connecting end 7, and the connecting end 7 can adopt a contact form (including end face contact, cylindrical side contact, sheet side contact), welding form, and elastic contact form, so as to be connected to the wiring. Furthermore, the connecting end 7 can adopt a closed structure to increase the contact area. The terminal body 10 is circumferentially provided with at least one contact spring arm 2 that is peeled off from the surface of the terminal body 10 and folded toward the inside of the terminal body 10 with the folded edge 13 as the boundary line, and the contact spring arm 2 is facing the front end of the terminal body 10. The use of the contact spring arm 2 can effectively increase the contact area with the male terminal and maintain stable contact of the terminal. The terminal body 10 is provided with at least one limiting spring arm 4 that is peeled off from the surface of the terminal body 10 and folded toward the outside of the terminal body 10 with the folded edge 2 13 as the boundary line. The use of the limiting spring arm 4 can effectively prevent the terminal from retreating after installation.

[0022] At least one outer bulge 9 is provided on the surface of the terminal body 10, which is suddenly turned outward from the terminal body 10. The outer bulge 9 is evenly distributed circumferentially on the terminal body 10. The highest point of the outer bulge 9 forms the maximum diameter of the terminal body 10, which can be used as the maximum outer diameter when the terminal is assembled, and is used to fix the terminal to limit its rotation in the installation shell. When the terminal body 10 is matched with the male terminal, there is enough springback margin when the contact spring arm 2 is supported.

[0023] The terminal body 10 is provided with an inner convex bulge 1 corresponding to the contact elastic arm 2 and suddenly mutating toward the inside of the terminal body 10. The inner convex bulge 1 and the contact elastic arm 2 are adjacently arranged and axially arranged on the terminal body 10, so that the inner convex bulge 1 guides the male terminal when the male terminal is docked with the terminal body 10, preventing the contact elastic arm 2 from being directly flipped over when the male terminal is plugged in, thereby ensuring the stability of the connection.

[0024] The docking protrusion 8 provided on one side of the docking edge of the terminal body 10 is docked with the docking recess 11 opened on the opposite side of the docking edge of the terminal body 10. At least one docking protrusion 8 is provided, thereby ensuring the stability of the terminal after the terminal body 10 is rolled and docked. The docking protrusion 8 and the docking recess 11 adopt a dovetail structure. This structure improves the accuracy of docking and the stability of the connection, and the terminal body 10 can withstand a certain axial load force.

[0025] The terminal body 10 is covered with rubber to form a silicone sealing ring 6 for sealing. This design is conducive to improving the sealing performance. Furthermore, a window 5 adjacent to the silicone sealing ring 6 can be opened on the terminal body 10 to facilitate liquid silicone mold injection molding.

[0026] At least one contact hole 12 is opened circumferentially on the terminal body 10, and the contact hole 12 is located in the encapsulated area of the silicone sealing ring 6 on the terminal body 10. Since the liquid silicone flows well during injection molding during encapsulation, this design can increase the bonding force between the silicone sealing ring 6 and the terminal body 10, thereby ensuring the stability of the connection between the two.

[0027] A wavy structure is formed on the outer surface of the silicone sealing ring 6, thereby achieving high-performance sealing.

[0028] The terminal body 10 is made of phosphor bronze, which has good electrical conductivity and thermal conductivity, as well as good machinability, and can therefore be used for stamping.

[0029] The terminal body 10 is provided with a window 5 for separating the connecting end 7. This design is conducive to crimping the connecting end 7 to the wiring. The purpose of providing the window 5 is to prevent the front end of the terminal body 10 from being deformed by liquid after crimping.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
