Description

Technical Field

[0001] This utility model relates to the field of connector processing technology, and in particular to a device for bending the pins of a printed circuit board connector. Background Technology

[0002] Multi-pin leaf spring connectors for circuit boards consist of a housing and multiple flat pins. Typically, the pins are straight; however, some connectors require bending the pins for easier mating. Currently, bending is done row by row. This method has drawbacks: it can easily deform both bent and unbent pins; it is inefficient; and the deformation of the pins during bending can affect the connection between the pins and the housing. Utility Model Content

[0003] This utility model provides a pin bending device for printed circuit board connectors to overcome the shortcomings of the prior art. It solves the problems of low efficiency and easy impact on the connection between the pin and the housing when bending the pin, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A printed circuit board connector pin bending device includes a long strip-shaped base, with side plates fixed to both ends of the base by screws, and a placement seat fixed to the base by screws. A pair of rotating shafts are rotatably mounted on the side plate. Inner plates are welded to the inner ends of the rotating shafts. A rotating bar is fixed between each pair of inner plates located on the same axis by screws. A swing plate is fixed to the rotating shaft on one side by a pin. An action long hole parallel to its length direction is opened on the swing plate. A movable rod is movably mounted in the action long hole. A pull plate is provided between the swing plates. The movable rod is fixed to the pull plate. The other end of the pull plate is threaded to a connecting rod through a screw at its end. An end plate is sleeved on the connecting rod. The end plate is fixed to the outer wall of the side plate. A cylinder is fixed on the end plate. The movable end of the cylinder is fixed to the other end of the connecting rod.

[0005] Furthermore, a limiting groove is formed at the upper opening of the placement seat.

[0006] Furthermore, a limiting pin is inserted into the outer wall of the side panel.

[0007] Furthermore, two pairs of limiting strips are inserted into the side plate, and an end pull block is welded to one end of each limiting strip. The end pull block is located on the outside of one of the side plates.

[0008] Furthermore, gripping grooves are provided on both sides of the end block.

[0009] The advantages of the above technical solution are: This invention employs a method of simultaneously bending two rows of pins when bending the pins. This bending method improves bending efficiency. During bending, each row of pins is threaded between each pair of rotating bars, and then the pins are bent under the action of the swing plate.

[0010] This invention provides a pair of limiting strips at the root of each row of pins to prevent the connection between the pins and the housing from being affected when the pins are bent. Attached Figure Description

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a further detailed description of this utility model in conjunction with the accompanying drawings.

[0012] Figure 1 A three-dimensional structure of one embodiment is shown. Figure 1 .

[0013] Figure 2 A three-dimensional structure of one embodiment is shown. Figure 2 . Detailed Implementation

[0014] like Figures 1-2 As shown, a printed circuit board connector pin bending device includes a long strip-shaped base 1, with side plates 2 fixed to both ends of the base 1 by screws. Limiting pins 39 are inserted into the outer wall of the side plates 2. A placement seat 5 is fixed to the base 1 by screws. Optionally, the upper end of the placement seat 5 is formed with a limiting groove.

[0015] A pair of rotating shafts 3 are rotatably mounted on the side plate 2. The inner end of the rotating shaft 3 is welded with an inner plate 30. A rotating bar 31 is fixed between each pair of inner plates 30 located on the same axis by screws. A swing plate 32 is fixed to the rotating shaft 3 on one side by a pin. An action long hole 33 parallel to its length direction is opened on the swing plate 32. A movable rod 34 is movably mounted in the action long hole 33. A pull plate 35 is provided between the swing plates 32. The movable rod 34 is fixed to the pull plate 35. The other end of the pull plate 35 is threaded to a connecting rod 36 through a screw at its end. An end plate 37 is sleeved on the connecting rod 36. The end plate 37 is fixed to the outer wall of the side plate 2. A cylinder 38 is fixed on the end plate 37. The movable end of the cylinder 38 is fixed to the other end of the connecting rod 36.

[0016] Two pairs of limiting strips 4 are inserted into the side plate 2. One end of the limiting strip 4 is welded with an end pull block 40. The end pull block 40 is located on the outside of one of the side plates 2. The end pull block 40 has a holding groove 41 on both sides.

[0017] In this embodiment, during operation, the operator inserts the two rows of pins of the connector between the two pairs of rotating bars 31, and then inserts the limiting bar 4 on the side plate 2. During insertion, each row of pins is located between each pair of limiting bars 4.

[0018] Then, the cylinder 38 is activated, and the connecting rod 36 moves under the drive of the cylinder 38. The movement of the connecting rod 36 will pull the pull plate 35 to move. The movement of the pull plate 35 will abut against the active hole 33 through the movable rod 34, thereby causing the swing plate 32 to rotate until the swing plate 32 located on the inner side and the limit pin 39 abut against each other. The rotation of the swing plate 32 will drive the rotating shaft 3 and each pair of rotating bars 31 to rotate downward by 90 degrees, thus achieving the bending operation of the pin. After the bending is completed, the limit bar 4 is pulled out, and then the connector is removed.

[0019] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
