[0001] The utility model relates to the technical field of connector processing, in particular to a pin bending jig. Background Art

[0002] The plug connector of the micro-rectangular connector consists of a housing and two rows of pins arranged at one end of the housing. In order to facilitate welding the connector to the circuit board, it is necessary to bend one row of pins by 90 degrees. Currently, most of the bending operations are carried out by automated bending equipment. Such equipment is usually used for the 90-degree bending of two rows of pins, so it cannot be applied to the special single-row 90-degree bending. Summary of the Utility Model

[0003] The utility model provides a pin bending jig to solve the above-mentioned deficiencies of the prior art, solve the problem that single-row pin bending cannot be carried out, and has strong practicability.

[0004] In order to achieve the purpose of the utility model, the following technology is proposed:

[0005] A pin bending jig includes a base plate. One end of the base plate is installed with an end plate. A plurality of jacks are opened at the lower end of the end plate, and a groove is opened at the upper end of the end plate. A plurality of positioning grooves are opened at the bottom of the groove. Through the provided positioning grooves, one row of pins to be bent is positioned to ensure the bending efficiency and effect of this row of pins. The jacks are used for the insertion of the other row of pins to position the connector.

[0006] A pair of vertical rods are installed at the upper end of the end plate. An L-shaped plate is sleeved on the vertical rods. A pressing block is arranged at the lower end of the L-shaped plate. A positioning groove is opened at the lower end of the pressing block. The positioning groove and the positioning groove are in one-to-one correspondence. A rotating pressing plate is rotatably arranged at the upper end of the vertical rod. The lower end of the rotating pressing plate acts on the upper wall of the L-shaped plate. Through the provided pressing block, it can position the pins to be bent. When bending, the pressing block is fixed on the pins to be bent to ensure the bending effect. And in order to facilitate the removal of the connector after bending, the pressing block is set to be in a movable state, and when positioning, the rotating pressing plate is also used to press and position the pressing block.

[0007] A pair of vertical guide rods are installed on the end plate. A limit nut is arranged at the upper end of the vertical guide rod. A compression spring is sleeved on the upper end of the vertical guide rod. The compression spring is located below the limit nut.

A bending rod is rotatably arranged between the movable sleeve plates. Outer extension rods are arranged at both ends of the movable sleeve plate. Through the provided bending rod, when the bending rod moves upward, it can act on the pins, thereby facilitating the bending operation of the pins. The vertical guide rod can ensure that the bending rod can only move upward along the vertical direction. At the same time, in order to improve the flexibility during movement, the bending rod is rotatably arranged.

[0008] On both sides of the substrate, upward-extending convex plates are installed. At the upper ends of the upward-extending convex plates, rocking arms are rotatably provided. Transverse holes are formed in the rocking arms, and an outer extension rod is inserted into the transverse holes. At the outer end of the rocking arm, an upper pull rod is provided.

[0015] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the drawings.

[0016] Figure 1 The three-dimensional structure of one of the embodiments is shown Figure 1 .

[0017] Figure 2 The enlarged view of part A is shown.

[0018] Figure 3 The three-dimensional structure of one of the embodiments is shown Figure 2 . Detailed Description of the Embodiment

[0019] As Figures 1 to 3 shown, a pin bending jig includes a substrate 1. One end of the substrate 1 is installed with an end plate 2. A plurality of jacks 22 are formed at the lower end of the end plate 2. A groove is formed at the upper end of the end plate 2, and a plurality of positioning grooves 21 are formed at the bottom of the groove.

[0020] A pair of vertical rods 3 are installed at the upper end of the end plate 2. An L-shaped plate 32 is sleeved on the vertical rod 3. A pressing block 33 is provided at the lower end of the L-shaped plate 32. A positioning groove 34 is formed at the lower end of the pressing block 33. The positioning groove 34 and the positioning groove 21 are in a one-to-one correspondence, and both the positioning groove 21 and the positioning groove 34 are in a semi-circular arc structure or a rectangular structure. A rotating pressing plate 30 is rotatably provided at the upper end of the vertical rod 3. The rotating pressing plate 30 is in an L-shaped structure. A circular plate is provided at the lower end of the rotating pressing plate 30. The lower end of the rotating pressing plate 30 acts on the upper wall of the L-shaped plate 32. A spring 31 is sleeved on the lower end of the vertical rod 3. The spring 31 is located on the lower side of the L-shaped plate 32.

[0021] A pair of vertical guide rods 420 are installed on the end plate 2. A limit nut 42 is provided at the upper end of the vertical guide rod 420. A compression spring 43 is sleeved on the upper end of the vertical guide rod 420. The compression spring 43 is located below the limit nut 42. A movable sleeve plate 44 is provided at the lower end of the compression spring 43. The movable sleeve plate 44 is sleeved on the vertical guide rod 420. A bent rod 45 is rotatably provided between the movable sleeve plates 44. Outer extension rods 46 are provided at both ends of the movable sleeve plate 44.

[0022] Upper extension convex plates 4 are installed on both sides of the base plate 1. A rocking arm 40 is rotatably provided at the upper end of the upper extension convex plate 4. A transverse hole 41 is formed in the rocking arm 40. The outer extension rod 46 is inserted into the transverse hole 41. An upper pull rod 47 is provided at the outer end of the rocking arm 40. A stop block 20 is provided on the side wall of the end plate 2 for limiting the rocking arm 40.

[0023] During the operation of this embodiment, the operator inserts the pin on the connector into the jack 22, the positioning groove 21 and the positioning groove 34.

[0024] Before insertion, the operator needs to rotate the rotating pressing plate 30 to apply a force to the L-shaped plate 32 through the rotating pressing plate 30, so as to position the pin through the pressing block 33.

[0025] After the pin is inserted, the operator pulls up the rocking arm 40 through the upper pull rod 47. When the rocking arm 40 rotates upward, the transverse hole 41 on it acts on the outer extension rod 46, so that the outer extension rod 46 and the bent rod 45 on it move upward along the vertical guide rod 420. And during the bending process, the compression spring 43 deforms. After the pin is bent upward, the pulling force on the upper pull rod 47 is cancelled. Thereafter, the bent rod 45 will move downward under the action of the compression spring 43.

[0026] Then rotate the rotating pressing plate 30 to cancel the action of the rotating pressing plate 30 on the L-shaped plate 32. Subsequently, the L-shaped plate 32 moves upward under the action of the spring 31, and then the connector is pulled out.
