Description

Technical Field

[0001] The utility model belongs to the technical field of wire connectors, and particularly relates to a crimping of a wire and a terminal post. Background Art

[0002] During the installation of an electrical appliance, it is necessary to crimp the metal coil of a wire onto the terminal post of a connector. The existing wiring method is generally to coil the metal wire into a coil, then place the metal coil on a metal contact piece, and use a fastening screw to fasten it, so that the bottom of the fastening screw makes crimping contact with the metal coil.

[0003] Although this method can crimp the coil, for some relatively thin metal coils, the connection by this method is unstable at the connection point, resulting in loosening and falling off of the metal wire at the connection point, and further affecting the normal use of the electrical appliance. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a crimping of a wire and a terminal post, which aims to improve the stability of the connection of the metal wire, so as to solve the above problems in the background art.

[0005] The technical solution for the utility model to solve the above technical problems is as follows: A crimping of a wire and a terminal post includes a socket. The top of the socket is divided into equidistant and multiple partition cavities by a partition plate. The top of the inner cavity of the partition cavity is fixedly connected with a top plate. The bottom of the inner cavity of the partition cavity is fixedly connected with a contact piece. A threaded cylinder is fixedly connected to the inside of the top plate in an embedded manner. A threaded bolt is threadedly connected to the inner surface of the threaded cylinder. The bottom of the threaded bolt is rotatably connected to a pressing piece through a bearing seat. The pressing piece is slidably arranged on one side wall of the inner cavity of the partition cavity. The bottom of the pressing piece is fixedly connected with bumps that are 180 degrees apart from each other front and back. The center of the top of the contact piece is fixedly connected with a terminal post. Two elastic pieces one are welded on both sides of the surface of the terminal post. The bottom of the elastic piece one is welded to the top of the contact piece. An elastic piece two is welded to the top of the contact piece at a position on the same horizontal line as the elastic piece one.

[0006] Preferably, a guiding seat is fixedly connected to the right side of the pressing piece. A guiding rail is fixedly connected to the side wall of the inner cavity of the partition cavity. The outer surface of the guiding rail is slidably connected to the inner surface of the guiding seat.

[0007] Preferably, a wire can be embedded and clamped between the elastic piece one and the elastic piece two.

[0008] Preferably, a through hole is opened at the bottom of the pressing piece, and the through hole penetrates through the top end face of the pressing piece.

[0009] Preferably, the diameter of the through hole is larger than the distance between the elastic piece one and the elastic piece two. The tops of the elastic piece one and the elastic piece two penetrate through the through hole and extend to the top of the pressing piece.

[0010] The beneficial effects of the present utility model are as follows:

[0011] In the present utility model, the metal wire is formed into a coil by using the existing technology and clamped between the first elastic piece and the second elastic piece. The horizontal position of the metal coil is limited by the self-elasticity of the first elastic piece and the second elastic piece. Then, a peripheral screwdriver is used to rotate the threaded bolt, and the threaded bolt rotates threadedly on the inner surface of the threaded cylinder. By means of threaded rotation and in cooperation with the bearing seat, the pressing piece is driven to move. Since the pressing piece and the inner wall of the partition cavity are slidably arranged, the pressing piece drives the convex block to move, and then the convex block presses against the surface of the metal pressing ring, thereby improving the stability between the metal coil and the connecting piece and avoiding the loosening and falling off of the metal coil;

[0012] 2. In the present utility model, by arranging the inner surface of the guiding seat to be slidably connected with the outer surface of the guiding rail, the up-and-down movement of the pressing piece can be guided;

[0013] 3. In the present utility model, by arranging the through hole, when the pressing piece moves downward, it can avoid pressing the first elastic piece and the second elastic piece, so as to prevent the first elastic piece and the second elastic piece from deforming under pressure.

The top of the socket 1 is divided into a plurality of equally spaced partition cavities 3 by a partition plate 2. A top plate 4 is fixedly connected to the top of the inner cavity of the partition cavity 3. A contact piece 5 is fixedly connected to the bottom of the inner cavity of the partition cavity 3. A threaded cylinder 6 is fixedly connected to the inside of the top plate 4 in an embedded manner. A threaded bolt 7 is threadedly connected to the inner surface of the threaded cylinder 6. The bottom of the threaded bolt 7 is rotatably connected to a pressing piece 9 through a bearing seat 8. The pressing piece 9 is slidably arranged on one side wall of the inner cavity of the partition cavity 3. A guiding seat 14 is fixedly connected to the right side of the pressing piece 9. A guiding rail 15 is fixedly connected to the side wall of the inner cavity of the partition cavity 3. The outer surface of the guiding rail 15 is slidably connected to the inner surface of the guiding seat 14. By setting the inner surface of the guiding seat 14 to be slidably connected to the outer surface of the guiding rail 15, the up and down movement of the pressing piece 9 can be guided. At the bottom of the pressing piece 9 and at a position where the front and rear are 180 degrees to each other, a convex block 10 is fixedly connected. At the center of the top of the contact piece 5, a terminal 11 is fixedly connected. On both sides of the surface of the terminal 11, a first elastic piece 12 is welded. The bottom of the first elastic piece 12 is welded to the top of the contact piece 5. At a position on the top of the contact piece 5 and at the same horizontal line as the first elastic piece 12, a second elastic piece 13 is welded. A wire can be embedded and clamped between the first elastic piece 12 and the second elastic piece 13. The metal wire is formed into a coil shape by using the prior art and is clamped between the first elastic piece 12 and the second elastic piece 13.

By using the threaded rotation method and cooperating with the bearing seat 8 to drive the pressing piece 9 to move. Since the pressing piece 9 and the inner wall of the partition cavity 3 are slidably arranged, the pressing piece 9 drives the convex block 10 to move, and further the convex block 10 presses on the surface of the metal pressing ring, thereby improving the stability between the metal coil and the contact piece and avoiding the situation of the metal coil loosening and falling off. Embodiment 2

[0023] Figures 1-4The crimping of a wire and a terminal of an embodiment of the present utility model is shown, including a socket 1. The top of the socket 1 is divided into a plurality of equally spaced partition cavities 3 by a partition plate 2. A top plate 4 is fixedly connected to the top of the inner cavity of the partition cavity 3, and a contact piece 5 is fixedly connected to the bottom of the inner cavity of the partition cavity 3. A threaded cylinder 6 is fixedly connected to the inside of the top plate 4 in an embedded manner. A threaded bolt 7 is threadedly connected to the inner surface of the threaded cylinder 6. The bottom of the threaded bolt 7 is rotatably connected to a pressing piece 9 through a bearing seat 8. A through hole 16 is formed in the bottom of the pressing piece 9, and the through hole 16 penetrates through the top end surface of the pressing piece 9. The diameter of the through hole 16 is larger than the distance between the first elastic piece 12 and the second elastic piece 13. The tops of the first elastic piece 12 and the second elastic piece 13 penetrate through the through hole 16 and extend to the top of the pressing piece 9. By providing the through hole 16, when the pressing piece 9 moves downward, it is avoided that the first elastic piece 12 and the second elastic piece 13 are pressed, so that the first elastic piece 12 and the second elastic piece 13 undergo pressure deformation. The pressing piece 9 is slidably arranged on one side wall of the inner cavity of the partition cavity 3. Two bumps 10 are fixedly connected to the bottom of the pressing piece 9 and are 180 degrees apart from each other front and back. A terminal 11 is fixedly connected to the center of the top of the contact piece 5. Two first elastic pieces 12 are welded to both sides of the surface of the terminal 11. The bottom of the first elastic piece 12 is welded to the top of the contact piece 5. A second elastic piece 13 is welded to the top of the contact piece 5 at a position on the same horizontal line as the first elastic piece 12.

[0024] Working principle: When the present utility model is used, an installer uses the existing technology and a tool to form the metal wire into a coil shape, and then clamps it between the first elastic piece 12 and the second elastic piece 13. The horizontal position of the metal coil is limited by the self-elasticity of the first elastic piece 12 and the second elastic piece 13. Then, an external flat-head screwdriver is used to rotate the threaded bolt 7. The threaded bolt 7 rotates threadedly on the inner surface of the threaded cylinder 6. By means of threaded rotation and in cooperation with the bearing seat 8, the pressing piece 9 is driven to move. The inner surface of the guiding seat 14 is slidably connected to the outer surface of the guiding rail 15, which can guide the up and down movement of the pressing piece 9. Thus, the pressing piece 9 drives the bump 10 to move, and further the bump 10 presses on the surface of the metal pressing ring, thereby improving the stability between the metal coil and the contact piece and avoiding the situation of loosening and falling off of the metal coil.
