[0026] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0027] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "inner," and "outer," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] Example 1: Figures 1 to 3 As shown, a two-pin solid plug inner frame includes a base 1 and two pins 2. The base 1 is provided with two mounting holes 11 corresponding to the two pins 2. The lower ends of the pins 2 are penetrated by corresponding mounting holes 11. The upper ends of the pins 2 are connected with the core wire 3. The upper ends of the pins 2 are provided with a wire insertion groove 21. One end of the core wire 3 extends into the wire insertion groove 21. The upper end of the base 1 is provided with a clamping member 4 and a pressing plate 5. The middle part of the pressing plate 5 is connected to the base 1 through the clamping member 4. The two ends of the pressing plate 5 are respectively provided with pressure heads 51. The pressure heads 51 correspond to the wire insertion groove 21 one by one. The pressure heads 51 extend into the corresponding wire insertion groove 21. The pressure heads 51 cooperate with the wire insertion groove 21 to press the end of the core wire 3 tightly.

[0029] In this embodiment, the pressing plate 5 includes a metal plate 52 and a plastic layer 53 covering the surface of the metal plate 52. The metal plate 52 plays a supporting role, and the plastic layer 53 plays an insulating role.

[0030] In this embodiment, a rubber sleeve 54 is provided on the pressure head 51. The rubber sleeve 54 has a certain elasticity so that the core wire 3 can fully contact with the wire insertion slot 21 to avoid a circuit breaker.

[0031] Example 2: Figure 1 、 Figure 2 and Figure 4 As shown, the rest of the parts are the same as those in Example 1, except that one side of the pressing plate 5 is recessed inward to form a plurality of first grooves 55, and the first grooves 55 pass through the upper and lower end surfaces of the pressing plate 5, and the other side of the pressing plate 5 is recessed inward to form a plurality of second grooves 56, and the second grooves 56 pass through the upper and lower end surfaces of the pressing plate 5, and both the first grooves 55 and the second grooves 56 are used for winding the core wire 3.

[0032] In this embodiment, the first grooves 55 and the second grooves 56 are arranged crosswise.

[0033] In the design of this structure, the pressure plate 5 is in a fishbone shape, which is convenient for winding the core wire 3 and improving the connection stability between the core wire 3 and the pressure plate 5. When the core wire 3 is subjected to tension, it is not easy to affect the end of the core wire 3, that is, the risk of the core wire 3 being separated from the wire insertion slot 21 is reduced.

[0034] Example 3: Figure 2 、 Figure 5 and Figure 6 As shown, the rest of the parts are the same as those in Example 1, except that the center of the base 1 protrudes upward to form a boss 12, and the upper end surface of the boss 12 is recessed downward to form a limiting groove 121 that matches the pressure plate 5. The limiting groove 121 runs through the left and right sides of the boss 12, and the front and rear sides of the boss 12 are respectively provided with a clamping groove 122. The clamping part 4 includes a limiting plate 41, and the front and rear sides of the lower end surface of the limiting plate 41 are respectively fixed with a hook 42. The middle part of the pressure plate 5 extends into the limiting groove 121, and the limiting plate 41 is pressed on the upper end surface of the pressure plate 5 and the upper end surface of the boss 12. The hook 42 corresponds to the clamping groove 122 one by one, and the hook 42 is clamped and matched with the corresponding clamping groove 122. The structure of the clamping part 4 is relatively simple, which is convenient for quick clamping and matching with the boss 12, and the assembly is relatively convenient.

[0036] In this embodiment, the diameter of the positioning column 123 gradually decreases from bottom to top, and the inner diameter of the positioning hole 57 gradually decreases from bottom to top, with a certain guide surface to facilitate alignment and assembly.

[0037] Example 5: Figure 2 、 Figure 5 and Figure 6 As shown, the rest of the parts are the same as those in Example 4, except that a screw hole 124 is provided at the upper end of the positioning column 123, and a through hole 411 and a bolt 43 are provided on the limiting plate 41. The through hole 411 and the screw hole 124 are located on the same axis. The bolt 43 passes through the through hole 411 and is threadedly connected to the screw hole 124, which helps to improve the stability of the connection.

[0038] During assembly, first wind the core wire 3 onto the pressing plate 5, then extend the end of the core wire 3 into the wire insertion slot 21, then extend the pressure head 51 at the end of the pressing plate 5 into the corresponding wire insertion slot 21, and the pressure head 51 cooperates with the wire insertion slot 21 to press the end of the core wire 3, and finally connect the middle part of the pressing plate 5 to the base 1 through the clamping piece 4.
