Description

Technical Field

[0001] The utility model relates to the technical field of electronic connector production, in particular to an electroplating crimping die which is convenient for adjusting and positioning. Background Art

[0002] The main purpose of connector electroplating in the prior art is to improve the conductivity, corrosion resistance and mechanical properties of the connector, and the press-in connector is an important connection device on the printed circuit board. Its installation method is to press multiple elastically deformable pins on the connector into the printed circuit board holes through interference fit.

[0003] The crimping device currently used is a simple crimping upper and lower mold device. First, the crimping upper and lower molds are made and a set of upper and lower molds are aligned and fixed on the press. Then the printed circuit board is placed on the upper and lower molds by hand, and the relative position of the printed circuit board and the crimping upper and lower molds is repeatedly adjusted. Finally, the crimping work is carried out after the position is visually checked to be appropriate. The disadvantage of this manual crimping method is that it is first impossible to achieve accurate positioning of the crimping upper and lower molds. The relative position relationship visually observed cannot meet the technical requirements, which easily causes misalignment of the upper and lower molds.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a plating crimping die that is easy to adjust and position is proposed. Utility Model Content

[0007] Furthermore, the clamping plates on both sides are "L"-shaped structures with opposite notches, and the clamping plates on both sides are fixed to the bottom edge of the lower mold base by fastening bolts.

[0008] Furthermore, a back plate is fixed by bolts at the rear end of the manual press, and a hand wheel is rotatably installed on the right side of the back plate.

[0009] Furthermore, a lifting and lowering pressure rod is vertically slidable inside the back plate, and the lifting and lowering pressure rod is connected to the hand wheel through a worm gear structure.

[0010] Furthermore, the end of the lifting and lowering pressure rod is connected to an upper mold assembly, and the upper mold assembly includes a frame, a mounting sleeve and connecting bolts. The top of the frame is integrally fixed with a mounting sleeve, and the mounting sleeve is threadedly fixed to the end of the lifting and lowering pressure rod through the connecting bolts.

[0011] Furthermore, the upper die assembly also includes a screw and an upper die seat. The screw is rotatably installed inside the frame, and the upper die seat is threadedly matched in the middle of the screw.
