Description

Technical Field

[0001] The utility model relates to the field of auxiliary equipment for processing connector pins, in particular to a connector pin bending tool. Background Art

[0002] A connector is a component used in electronic devices for the purpose of connecting or disconnecting electrical circuits, which has functions such as providing electrical connection, mechanical connection, signal transmission, etc., and has good flexibility.

[0003] A connector includes components such as a housing and pins, and generally, a connector usually has a plurality of pins. Some pins of the connector are straight, and some pins of the connector are bent. In order to produce a connector with bent pins, it is necessary to bend a large number of pins before production. However, due to the variety of connectors, pins of different lengths need to be used, and sometimes the bending positions of pins with the same length are also different. Therefore, it is difficult to use a unified device for pin bending. Usually, manual bending is adopted, and it is difficult to guarantee the accuracy and the efficiency is low. Summary of the Utility Model

[0004] In view of the above defects, the utility model provides a connector pin bending tool, which can conveniently bend a plurality of pins at one time, and can improve the accuracy of the bending position compared with the prior art.

[0005] In order to achieve the purpose of the utility model, the following technology is proposed:

A linear mechanism is arranged on one side of the inclined plate, and a pressing block for bending the pin is arranged at one end of the output shaft thereof.

[0008] An upper cover unit is assembled on one side of the moving bending unit, including a cover plate. A plurality of second semi-circular grooves are formed on one side of the cover plate, which are respectively used to combine with the first semi-circular grooves to form circular grooves. The length of the second semi-circular groove is equal to the distance from one end of the pin to the bending point.

[0009] Furthermore, a plurality of L-shaped brackets are arranged on the opposite side of the inclined plate where the first semi-circular grooves are formed, and the linear mechanism is arranged at the upper end of the vertical part of the L-shaped bracket.

[0011] Further, a T-shaped portion is provided at the other end of the inclined plate. The moving bending unit further includes a guide block. The guide block is provided with a T-shaped groove along a direction parallel to the axis of the first semi-circular groove. One side of the T-shaped groove penetrates to the outside of one end face of the guide block, and a part of the T-shaped portion is slidably fitted in the T-shaped groove.

[0012] Further, a first through hole is provided at the connecting portion between the T-shaped portion and the inclined plate. A convex plate is further provided on one end face of the T-shaped groove. The convex plate is provided with a second through hole matching the first through hole.

[0021] The present application will be further described below with reference to the drawings and embodiments.

[0022] As Figures 1 to 4 shown, a connector pin bending tool includes a moving bending unit 1 and an upper cover unit 2.

[0023] The moving bending unit 1 includes an inclined plate 11 that is inclined and moves along a straight line at an acute angle to the horizontal plane. Along the edge of the inclined plate 11 at the highest point, a plurality of first semi-circular grooves 12 are provided along the moving direction of the inclined plate 11. On the opposite side of the inclined plate 11 where the first semi-circular grooves 12 are provided, a number of L-shaped brackets 13 are provided. At the upper end of the vertical part of the L-shaped bracket 13, a linear mechanism 14 is provided. In this embodiment, the linear mechanism 14 adopts a single-axis linear cylinder, and one end of its output shaft is provided with a push plate 141. On one side of the push plate 141, a pressing block 15 for bending the pin is provided. One end of the inclined plate 11 is also provided with a connecting rod, and one end of the connecting rod is provided with a controller 16. A single-chip microcomputer electrically connected to the linear mechanism 14 is provided in the controller 16. A button 161 is provided on the controller 16. The other end of the inclined plate 11 is provided with a T-shaped part 17. A first through hole 18 is provided at the connecting part of the T-shaped part 17 and the inclined plate 11. The moving bending unit 1 further includes a guide block 19 provided on a bracket. The guide block 19 is provided with a T-shaped groove 191 along the direction parallel to the axis of the first semi-circular groove 12. One side of the T-shaped groove 191 penetrates to the outside of one end face of the guide block 19. A part of the T-shaped part 17 is slidably fitted in the T-shaped groove 191. A convex plate 192 is provided on one end face of the T-shaped groove 191. A second through hole matching the first through hole 18 is provided on the convex plate 192. When the T-shaped part 17 rises to the highest position in the T-shaped groove 191, the inclined plate 11 is fixed by inserting a pin 193 into the first through hole 18 and the second through hole.

[0024] The upper cover unit 2 is assembled on one side of the moving bending unit 1 and includes a cover plate 21. The length of the cover plate 21 in the direction parallel to the axis of the first semi-circular groove 12 is less than the length of the inclined plate 11 in the direction parallel to the axis of the first semi-circular groove 12. A plurality of second semi-circular grooves 22 for combining with the first semi-circular grooves 12 into circular grooves are provided on one side of the cover plate 21. The length of the second semi-circular groove 22 is equal to the distance from one end of the pin to the bending point. In this way, by assembling the second semi-circular grooves 22 with different lengths, bending processing can be carried out on various pins and in the case where various different bending point positions are required for the pins. L-shaped hanging brackets 23 are respectively provided at both ends of the cover plate 21. An insertion block 24 is provided on the lower side of the horizontal part of the L-shaped hanging bracket 23. The upper cover unit 2 further includes a pair of seat bodies 25 respectively provided on a bracket. A slot 26 matching the insertion block 24 is provided on an upper side of the seat body 25.

[0025] After the upper cover unit 2 is assembled, pins are respectively placed in each circular groove. During work, first remove the pin 193 to make the inclined plate 11 movable, and then slowly lower the inclined plate 11. When it is visually observed that the upper surface of the inclined plate 11 and the upper surface of the cover plate 21 are in the same plane, that is, the upper ends of the first semi-circular groove 12 and the second semi-circular groove 22 are combined into a circular opening, press the button 161, and the controller 16 controls the linear mechanism 14, and the pressing block 15 bends each pin.

[0026] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various modifications and variations can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
