[0019] Example

[0020] A lead bending tool for a micro rectangular connector, the bending tool comprising a base plate 5, a fixing block 7, a side plate 3 and a pressing plate 2; the base plate 5 is provided with a groove 13, the fixing block 7 is installed in the groove 13, and the fixing block 7 is used to fix a part 9 with a lead 6 in the groove 13; the base plate 5 is fixed to the side plate 3, the pressing plate 2 and the side plate 3 are detachably connected by bolts 4, and the pressing plate 2 rotates along the bolts 4 to achieve up and down flipping; the pressing plate 2 is provided with a plurality of through grooves 1, and the through grooves 1 can allow part of the leads 6 to pass through; when the pressing plate 2 is flipped downward to fit with the base plate 5, the leads 6 on the part 9 are bent.

[0021] In one embodiment, a fixing groove 8 is provided in the middle of the fixing block 7, and the part 9 is embedded in the fixing groove 8 to be fixed; there are two fixing blocks 7, and the two fixing blocks 7 are symmetrically placed in the groove 13, so that the fixing groove 8 faces inward; the outer side of the fixing block 7 is tightly matched with the groove 13. When in use, the part 9 with a lead and the two fixing blocks 7 are put into the groove 13 together, and the two fixing blocks 7 clamp the part 9, and the protruding part of the upper end of the part 9 is embedded in the fixing groove 8 in the middle of the fixing block 7, so that the part 9 with a lead and the fixing block 7 are fixed in the groove 13 together.

[0022] In one embodiment, the upper inner corner of the fixing block 7 is designed to be an R angle 12. Under the downward pressure of the pressing plate 2, the lead 6 will be bent along the upper edge of the fixing block 7; the upper inner corner of the fixing block 7 is designed to be an R angle 12, so that the lead 6 forms an R angle 12 at the bend, preventing the lead 6 from breaking, cracking, and other problems during the bending process.

[0023] In one embodiment, the leads 6 on the part 9 include two rows, namely, a first row of leads 11 and a second row of leads 10; the pressing plate 2 includes two specifications, namely, a first pressing plate and a second pressing plate; the through slots 1 on the first pressing plate are used to allow one of the first row of leads 11 or the second row of leads 10 to pass through. The through slots 1 on the first pressing plate and the second pressing plate are arranged at different positions. The through slots 1 on the pressing plates of the two specifications are arranged at different positions. When the first pressing plate is pressed down, one of the first row of leads 11 or the second row of leads 10 will pass through the through slots 1 on the first pressing plate, and the remaining row of leads will be bent; then a pressing plate of another specification is replaced, and the remaining row of leads is bent, thereby achieving the bending of double rows of leads.

[0024] The specific working method of the above-mentioned bending tool is as follows: first, the bottom plate 5, the side plate 3 and the first pressure plate are connected with bolts 4, and the part 9 with leads is fixed in the groove 13 of the bottom plate 5 through two fixing blocks 7, and the first pressure plate is rotated to make the second row of leads 10 pass through the through groove 1 on the first pressure plate to ensure that the first pressure plate can be pressed on the first row of leads 11, and the first pressure plate is rotated at a constant speed until the first pressure plate and the bottom plate 5 are completely fitted together; after the first row of leads 11 are bent, the first pressure plate is removed, and the second pressure plate is connected to the bottom plate 5 and the side plate 3 with bolts 4, and the second pressure plate is rotated at a constant speed until the second pressure plate is close to the bottom plate 5. After the second row of leads 10 are bent, the second pressure plate is lifted, and the fixing blocks 7 and the part 9 are taken out of the groove 13 of the bottom plate 5 at the same time. At this point, both rows of leads are bent.

[0025] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The scope of patent protection of the present invention should be limited by the claims.
