[0036] This embodiment provides a female terminal. Figures 1 to 3 As shown, the female terminal includes a terminal body 1 and an elastic abutment 2. The terminal body 1 includes a plug-in portion 11, and the plug-in portion 11 includes a plurality of side panels 111. The plurality of side panels 111 are connected end to end in sequence and enclose together to form a plug-in hole 1101. The elastic abutment 2 includes a plug ring 21 and an elastic pressing piece 22 provided on the plug ring 21. The male terminal can be inserted into the plug-in hole 1101 through the plug ring 21, and the elastic pressing piece 22 is used to press the male terminal. At least one side panel 111 is provided with a clamping plate 112 extending outward from the first end of the plug-in hole 1101. The clamping plate 112 is provided with a clamping hole 1121. The plug ring 21 is provided with a clamping joint 211. The clamping joint 211 is used to clamp with the clamping hole 1121 when the plug ring 21 is inserted from the second end of the plug-in hole 1101 and moved into place. An abutment head 1122 is extended from the clamping plate 112 , and the abutment head 1122 is used to abut against the insert ring 21 .

[0037] In this embodiment, when the terminal body 1 and the elastic abutment 2 are installed, the plug ring 21 of the elastic abutment 2 is inserted from the second end of the plug hole 1101 and moves toward the first end of the plug hole 1101, that is, the end of the terminal body 1 provided with the snap-in hole 1121. When the elastic abutment 2 moves into position in the plug hole 1101, the snap-in joint 211 moves to the snap-in hole 1121 and snaps with the snap-in hole 1121, and at the same time, the plug ring 21 abuts against the abutment 1122 on the snap-in plate 112, thereby realizing reliable positioning and fixation of the elastic abutment 2. The above-mentioned female terminal has a simple structure, and the elastic pressing piece 22 is assembled separately from the terminal body 1. There is no need to process a complex structure on the terminal body 1 with a smaller size, and it is easy to process and manufacture, and no external connectors such as screws are required, so it is easy to install.

[0038] Specifically in this embodiment, the plug-in portion 11 includes four side panels 111, and the four side panels 111 together enclose a rectangular plug-in hole 1101. The plug-in ring 21 includes four ring plates 212, and the four ring plates 212 together enclose a rectangular through hole. The two side panels 111 arranged opposite to each other along the first direction are both provided with a snap-in plate 112 extending outward, and each snap-in plate 112 is provided with a snap-in hole 1121; the two ring plates 212 arranged opposite to each other along the first direction are respectively provided with snap-in joints 211. Specifically, the direction a in the accompanying drawings refers to the first direction. Specifically, when the plug-in ring 21 is moved into position relative to the plug-in hole 1101, the snap-in joints 211 on the two ring plates 212 arranged opposite to each other along the first direction of the plug-in ring 21 are respectively snapped into the corresponding snap-in holes 1121, thereby ensuring the effective positioning between the elastic abutment 2 and the terminal body 1.

[0039] Further, each clamping plate 112 is provided with abutment joints 1122 extending on both sides opposite to each other along the second direction, and a positioning space 1102 is formed between the two abutment joints 1122 located on the same side along the second direction. The two ring plates 212 arranged opposite to each other along the second direction are provided with first positioning heads 2121, and the first positioning heads 2121 are arranged in one-to-one correspondence with the positioning spaces 1102. Specifically, the direction b in the accompanying drawings refers to the second direction, and the first direction is perpendicular to the second direction. Specifically, when the plug ring 21 is inserted from the second end of the plug hole 1101 and moved into position, the first positioning head 2121 extends into the corresponding positioning space 1102 and abuts against the abutment joints 1122 on both sides corresponding to the same side. The abutment between the first positioning head 2121 and the abutment joint 1122, and the clamping between the clamping joint 211 and the clamping hole 1121, effectively ensure the reliable fixation of the elastic abutment 2 relative to the terminal body 1 when it is plugged into place, and avoid the elastic abutment 2 from moving along the first direction.

[0040] In this embodiment, the c direction refers to the third direction, which is the extending direction of the plug hole 1101 and the through hole. The first direction, the second direction and the third direction are perpendicular to each other.

[0041] Furthermore, the clamping plate 112 and its two abutting joints 1122 jointly form a positioning groove 1103, and the two ring plates 212 arranged opposite to each other along the first direction are both provided with second positioning heads 2122, and the second positioning heads 2122 are arranged one-to-one in correspondence with the positioning groove 1103. Specifically, when the plug ring 21 is inserted from the second end of the plug hole 1101 and moved into position, the second positioning head 2122 extends into the corresponding positioning groove 1103 and abuts against the corresponding two abutting joints 1122. The clamping connection between the clamping joint 211 and the clamping hole 1121, and the abutment between the first positioning head 2121 and the abutting joint 1122, further ensures that the elastic abutting joint 2 is reliably fixed relative to the terminal body 1 when it is inserted into position, and avoids the elastic abutting joint 2 from moving along the second direction.

[0042] In this embodiment, the clamping plate 112 is integrally formed with the side panel 111. Since the clamping plate 112 and the side panel 111 have simple structures, the two are integrally formed, eliminating the process of separate assembly of the clamping plate 112 and the side panel 111, thereby improving production and assembly efficiency.

[0043] In this embodiment, the abutment head 1122 is integrally formed with the clamping plate 112. Since the abutment head 1122 and the clamping plate 112 have simple structures, the abutment head 1122 and the clamping plate 112 are integrally formed, eliminating the process of separate assembly of the abutment head 1122 and the clamping plate 112, thereby improving production and assembly efficiency.

[0044] In this embodiment, two adjacent side panels 111 are connected by a rounded corner for smooth transition. The rounded corner can smoothly connect the two side panels 111 and avoid the appearance of a sharp point structure at the connecting portion 12 of the two side panels 111.

[0045] In this embodiment, the terminal body 1 further includes a connecting portion 12 connected to the plug-in portion 11 , and a fixing hole 121 for fixing with an external fixing end is formed on the connecting portion 12 .

[0046] In this embodiment, the elastic pressing pieces 22 are arranged in pairs. The elastic pressing pieces 22 have first bent pressing sections 221 . The first bent pressing sections 221 of the two elastic pressing pieces 22 are bent in directions toward each other.

[0047] Specifically, when the male terminal passes through the penetration hole and enters the plug-in hole 1101, the first bent pressing sections 221 of the two elastic pressing pieces 22 press the insertion end of the male terminal at the same time. The elastic force generated by the deformation of the elastic pressing piece 22 provides positive pressure to the contact part of the male terminal, ensuring stable contact and stable current signal between the male terminal and the female terminal.

[0048] Specifically, a second bent pressing section 222 is extended from one end of the first bent pressing section 221 facing away from the insert ring 21. The second bent pressing sections 222 of the two elastic pressing sheets 22 are bent in directions away from each other, and the second bent pressing sections 222 are used to abut against the side panel 111. Specifically, when the first bent pressing section 221 is squeezed and deformed, the second bent pressing section 222 is deformed at the same time, and the second bent pressing section 222 can abut against the side panel 111, and the two can form a fulcrum. At the fulcrum, the side panel 111 can apply force to the first bent extrusion end through the second bent extrusion section to increase the elastic force acting on the first bent pressing section 221.

[0049] Specifically, the first bending and pressing section 221 and / or the second bending and pressing section 222 are provided with hollow holes 2201. The hollow holes 2201 are provided to effectively reduce the material used for the natural tablet, reduce weight and reduce costs, while ensuring reliable abutment.

[0050] In this embodiment, the insert ring 21, the first bending and pressing section 221 and the second bending and pressing section 222 are integrally formed. Since the insert ring 21, the first bending and pressing section 221 and the second bending and pressing section 222 have simple structures, the three are integrally formed, eliminating the process of separate assembly of the insert ring 21, the first bending and pressing section 221 and the second bending and pressing section 222, thereby improving production and assembly efficiency.

[0051] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
