[0028] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0029] This utility model provides a novel integrated upper and lower structure conversion female terminal. By providing an intermediate plate 110 within the cavity 101 of the frame, the cavity 101 is divided into two independent sub-cavities 111. A first insertion panel 200 and a second insertion panel 300 are respectively formed within the sub-cavities 111, so that a insertion groove 112 for interlocking with the male plug is defined between the first insertion panel 200 and the second insertion panel 300. Through the above structure, the insertion groove 112 is formed on the frame, and the two insertion grooves 112 are arranged side by side in the vertical direction, thereby reducing the overall size of the conversion female terminal, making the structure more compact and simple, and adaptable to more places.

[0030] Specifically, such as Figure 1-4As shown in the figure, the high current conversion female terminal with an integrated upper and lower structure provided by this utility model includes a frame 100, and a through chamber 101 is provided inside the frame 100. The two ends of the chamber 101 form openings. An intermediate plate 110 is also provided inside the chamber 101. The intermediate plate 110 divides the chamber 101 into two independent sub-cavities 111. Two first plug-in panels 200 and second plug-in panels 300 are respectively arranged side by side with the intermediate plate 110. One end of the first plug-in panel 200 is formed on the top / bottom of the frame 100, and the other end is bent and extends into the sub-cavity 111. One end of the second plug-in panel 300 is formed on the intermediate plate 110, and the other end is bent and extends into the sub-cavity 111 corresponding to the first plug-in panel 200. The boundary between the first plug-in panel 200 and the second plug-in panel 300 defines a male terminal plug-in groove 112.

[0031] During use, a first plug-in panel 200 and a second plug-in panel 300 are respectively formed in the two compartments 111, so that each of the two compartments 111 has a plug-in groove 112 for plugging into the male plug terminal 400. This adapter can connect the two male plug terminals 400. Through the technical solution of this utility model, the two plug-in grooves 112 can be arranged side by side in the vertical direction, thereby reducing the size of the adapter female terminal. There is no need to set a connecting component between the two plug-in grooves 112 for connection, resulting in a simpler structure.

[0032] In this embodiment, as Figure 4 The first plug-in panel 200 includes, along its length, a first folding portion 201, a first elastic portion 202, and a first tail portion 203. The first folding portion 201 has an arc structure, with one end integrally formed with the top / bottom of the frame 100. One end of the first elastic portion 202 is formed on the first folding portion 201, and the other end extends along the length of the cavity 111. The first elastic portion 202 protrudes away from the top / bottom of the frame 100. The first tail portion 203 is formed on the first elastic portion 202, and the other end is inclined towards the top / bottom of the frame 100 and abuts against the top / bottom of the frame 100.

[0033] Similarly, the second plug-in panel 300 includes, along its length, a second folding portion 301, a second elastic portion 302, and a second tail portion 303. The second folding portion 301 has an arc structure, with one end integrally formed with the middle plate 110 of the frame 100. One end of the second elastic portion 302 is formed on the second folding portion 301, and the other end extends along the length of the cavity 111. The second elastic portion 302 protrudes in a direction away from the middle plate 110 and is correspondingly arranged with the first elastic portion 202. The second tail portion 303 is formed on the second elastic portion 302, and the other end is inclined towards the middle plate 110 and abuts against the middle plate 110.

[0034] The first plug-in panel 200 and the second plug-in panel 300 clamp the male plug terminal 400 through the first elastic part 202 and the second elastic part 302, so that the male plug terminal 400 can have sufficient contact surface and pressure with the two plug-in panels after being inserted into the plug-in slot 112, thereby ensuring the reliability of plugging and signal transmission.

[0035] In this embodiment, at least one of the first elastic portion 202 and the second elastic portion 302 is provided with a wavy protrusion. Increasing the wavy protrusion enhances the elasticity of both the first elastic portion 202 and the second elastic portion 302, strengthening the clamping force on the male terminal 400 and ensuring reliable connection. In this embodiment, the first elastic portion 202 has a wavy protrusion, and the second elastic portion 302 has a curved raised surface. By providing the second elastic portion 302 with a curved raised surface, a larger contact area with the male terminal 400 is ensured, thereby guaranteeing a higher current-carrying capacity.

[0036] In this embodiment, an insertion interface 113 is defined between the first folding portion 201 and the second folding portion 301, and the two insertion interfaces 113 located in the two compartments 111 are respectively located at both ends of the frame 100. By staggering the insertion interfaces 113, the two male terminals 400 can be inserted into the adapter female terminal in two opposite directions, thereby ensuring that the two male terminals 400 do not affect or interfere with each other during the insertion process.

[0037] In this embodiment, a plurality of mutually parallel weakening grooves 204 are provided on the first plug-in panel 200, and the weakening grooves 204 extend from the first folded portion 201 to the first tail portion 203. Providing the weakening grooves 204 on the first panel reduces the strength of the first plug-in panel 200, making it easier to undergo elastic deformation, thus facilitating the insertion of the male terminal 400 into the plug slot 112 at the plug interface 113. In this embodiment, the second plug-in panel 300 is configured as a finished surface, which, while facilitating the insertion of the male terminal, also ensures sufficient contact area with the male terminal, thereby guaranteeing the current-carrying capacity of the female adapter terminal.

[0038] To ensure the clamping force between the insertion slot 112 and the male terminal 400, and to guarantee the reliability after insertion, a first protrusion 205 corresponding to the first tail 203 is provided on the top / bottom of the frame. The first protrusion 205 abuts against the first tail 203 and lifts it up. At the same time, a second protrusion 304 corresponding to the second tail 303 is formed on the intermediate plate 110. The second protrusion 304 abuts against the second tail 303 and lifts it up.

[0039] In other words, by setting the first protrusion 205 and the second protrusion 304, the first tail 203 and the second tail 303 are lifted up, so that the second elastic part 302 and the second elastic part 302 are close to each other, thereby reducing the space of the insertion slot 112 and improving the insertion reliability of the male terminal 400 after the male terminal 400 is inserted.

[0040] like Figure 4-5 As shown, the frame 100 is made of folded sheet metal. It is composed of four side panels 103 and three main panels 102 arranged interlaced along the length direction. The width of the side panels 103 is half the width of the main panels 102. The first plug-in panel 200 is formed on one side edge of the main panels 102 located at both outer ends, and the second plug-in panel 300 is formed on both sides edge of the main panel 102 located in the middle. This utility model provides a frame 100 that is integrally formed from a single metal sheet. By folding the main board 102 and the side panels 103 together, a whole is formed, making the structure of the frame 100 more reliable and robust. In this embodiment, the two main boards 102 on both sides form the top and bottom of the frame 100, respectively, and the main board 102 in the middle forms the middle plate 110. The four side panels 103 are spliced ​​in pairs to form the side panels 103 of the frame 100. In order to achieve fixation after assembly, dovetail-shaped locking blocks are formed on the side panels 103 at both ends, and dovetail-shaped locking grooves are formed on the corresponding side panels 103, thereby achieving fixation after the sheet metal is folded and assembled.

[0041] The high-current conversion female terminal with an integrated upper and lower structure provided by this utility model embodiment can increase the contact area between the male terminal 400 and the male terminal 400 through the second contact panel after the male terminal 400 is inserted, thereby ensuring a large current carrying capacity and transmitting large currents. After the male terminal 400 is inserted into the insertion slot 112, the first insertion panel 200 and the second insertion panel 300 can reliably clamp and fix the male terminal 400, ensuring reliability after insertion. Through this technical solution, the two insertion slots 112 are arranged side by side in the upper and lower direction, thereby greatly reducing the overall size of the conversion female terminal. The one-piece molding process ensures the reliability of the terminal structure.
