[0038] The main body part 1 and the two connecting parts 2 are integrated structures.

[0039] In this embodiment, the conductive terminal is used to connect two lines, when connecting the lines, the elastic plate is pressed down, so that the inner end of the elastic plate is separated from the top surface of the cavity, and there is a vertical spacing between the two, then the lines are inserted into the cavity above the elastic plate, the pressing force of the elastic plate is released, the inner end of the elastic plate is automatically moved upward by the restoring force of the elastic plate, and the lines are pressed between the elastic plate and the bottom surface of the cavity, wherein the conductive terminal is made of a conductive metal material, after the lines on both sides are respectively clamped between the cavity and the corresponding elastic plate, the lines are limited by the elastic force of the elastic plate, and the electric connection of the two lines can be realized by the conductive terminal. In this embodiment, the main body part, the two connecting parts, the connecting plate and the elastic plate are integrated structures, and the connecting plate and the main body part are also integrated structures, which are directly stamped and bent from a metal plate, so that the manufacturing process is simpler, and the reliability and strength of the structure are better. Moreover, the inner end of the elastic plate is completely in the cavity, for example, in the direction shown in the figure, the two connecting parts are respectively arranged at the left end and the right end of the main body part, the inner end of the elastic plate is limited in front and back by the cavity, and the elastic deformation of the inner end of the elastic plate is limited by the top of the cavity upward, and the deformation downward is limited by the bottom of the cavity, that is, the inner end of the elastic plate can only deform upward and downward within the vertical height range of the cavity, so that when the lines are inserted into the cavity, the elastic plate in the restored state can abut against the inner wall of the cavity, and the stable electric connection and limitation of the lines and the conductive terminal are ensured.

[0040] As shown in the figure, the outer end of the elastic plate 5 is connected with the outer end of the connecting plate 4 through the arc-shaped plate 6. Figs. 1-4

[0041] ​The arc-shaped plate and the elastic plate and the connecting plate are in an integrated structure, the arc-shaped plate constitutes an arc-shaped bending part, in this way, the elastic deformation ability and the elastic recovery ability of the elastic plate can be ensured, and after the elastic plate is compressed, the arc-shaped plate can be used for supporting, and also plays a role of elastic deformation transition, prevents the breakage and plastic deformation of the connecting part between the elastic plate and the connecting plate.

[0042] As shown in Figs. 1-4 Each of the extension plates 7 is arranged above the corresponding elastic plate 5.

[0043] In this embodiment, the extension plates are arranged on the left side and the right side of the main body part, the arrangement of the extension plates can increase the length projected above the elastic plate, when the circuit is clamped between the elastic plate and the top surface of the cavity, the extension plate can increase the contact area with the circuit, thereby further ensuring the stability of the electrical connection between the circuit and the conductive terminal, and preventing the occurrence of poor contact.

[0044] As shown in Figs. 1-3 The two connecting parts 2 are arranged at the two ends of the main body part 1, and the main body part 1 is provided with elastic limiting parts 8 extending outward on the other two side walls.

[0045] The side wall of the main body part 1 at the elastic limiting part 8 is provided with a side part through groove 9 in communication with the cavity 3, one end of the elastic limiting part 8 is connected with one end of the side part through groove 9, and the other end is arranged outside the main body part 1 and opposite to the side part through groove 9. When the metal plate is punched to punch out the side part through groove, the side part through groove is punched to form the elastic limiting part, which is convenient to manufacture and is formed by integrated punching.

[0046] The extension directions of the two elastic limiting parts 8 are opposite.

[0047] With the direction of the figure as an example, two elastic limiting parts are arranged on the front side wall and the rear side wall of the main body part respectively. The left end of the elastic limiting part on the front side is connected with the left side wall of the front side side part through groove, the right end of the elastic limiting part on the front side is arranged on the front end of the main body part, and the elastic limiting part on the front side is arranged backward from right to left. The right end of the elastic limiting part on the rear side is connected with the right side wall of the rear side side part through groove, the left end of the elastic limiting part on the rear side is arranged on the rear end of the main body part, and the elastic limiting part on the rear side is arranged forward from left to right. By arranging two elastic limiting parts, when the conductive terminal is assembled in the connector, the elastic deformation of the elastic limiting part can be used to abut against the connector, so that the conductive terminal and the connector can be quickly assembled. When assembled, the mounting position in the connector is arranged to be adapted to the width of the main body part or slightly larger than the width of the main body part, the conductive terminal is inserted into the mounting position, but the distance between the two limiting parts is greater than the width of the mounting position, so that the mounting position can press the elastic limiting parts on both sides, and the elastic limiting parts can be abutted against the mounting position by the restoring force, so that the limiting of the conductive terminal is realized. Further, the extension directions of the two elastic limiting parts are opposite, two blocks can be arranged in the mounting position, and each block is arranged opposite to an elastic limiting part. The front block is arranged on the right side of the front elastic limiting part, and the rear block is arranged on the left side of the rear elastic limiting part. At this time, no matter whether the conductive terminal is subjected to leftward or rightward pulling force, the conductive terminal can be limited to move leftward and rightward by the elastic limiting part on one side and the corresponding block, so that the movement limiting of the conductive terminal is realized, and the firmness of the conductive terminal after assembly is ensured. When assembled, for example, when inserted into the mounting position of the connector from left to right, the rear block will first contact the rear side of the rear elastic limiting part. Since the rear elastic limiting part is arranged forward from left to right, the rear block can press the rear elastic limiting part, so that the rear elastic limiting part is elastically deformed and retracted into the rear side part through groove. After passing the rear block, the rear elastic limiting part returns to the original state, so that the rear elastic limiting part is arranged on the right side of the rear block. At this time, the front elastic limiting part is arranged on the left side of the front block, and the front elastic limiting part cannot continue to move rightward because the right end of the front elastic limiting part abuts against the block, so that the limiting is realized. Similarly, if the conductive terminal is subjected to leftward pulling force at this time, the left end of the rear elastic limiting part abuts against the rear block, so that the rear elastic limiting part cannot move leftward, and the two elastic limiting parts can realize the optimal movement of the conductive terminal.
