Description

Assembly die of wiring chuck

Technical Field

The utility model relates to the technical field of electricity, in particular to an assembling die of a wiring chuck.

Background

In the middle of electrical equipment, can use binding clip or binding post to carry out the connection of circuit usually, different with the welding, this kind of connected mode only need fix the electric wire on the chuck of binding clip or terminal afterbody usually, make cable and chuck paste tightly through the punching press assembly and can realize being connected of circuit, compare in the welding, this kind of mode has not only reduced the use of soldering tin, and the production cost is reduced, cold pressing just can the shaping, production efficiency improves greatly, the crimping position is difficult for droing after buckling simultaneously, and stability is good.

However, the existing cold pressing wire chuck and the assembling means thereof are not reasonable, most of the cold pressing wire chuck bends the tilted side plates at the two sides of the chuck downwards onto the cable, so that the contact area between the chuck and the cable is small, the chuck is not firm in fixation, the chuck is easy to fall off to cause the increase of defective rate, more gaps are left at the two sides of the chuck, the wire core exposed out of the insulating sheath part can move to the gap part after being pressed, the contact area between the wire core and the chuck is reduced, and poor contact is caused.

Therefore, in order to overcome the defects of the existing clamping head and the assembling means, a new wire connecting clamping head and an assembling die thereof need to be provided.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an assembly die of a wiring chuck, which solves the defects of the existing equipment.

The technical scheme adopted by the utility model for solving the technical problems is as follows: an assembly die of a wiring chuck comprises an upper die and a lower die, wherein a fixed rod is arranged above the upper die, and a base is arranged below the lower die; the upper die and the lower die are both provided with U-shaped grooves, and the U-shaped grooves are in a grid shape; the upper die U-shaped groove and the lower die U-shaped groove are arranged correspondingly; go up mould U type recess grid and lower mould U type recess grid setting of staggering each other.

The utility model has the following beneficial effects: the side plate of the jointing clamp head is provided with a plurality of anti-slip teeth which correspond to each other in position, and when the side plate is bent, the anti-slip teeth are staggered with each other to form a self-locking structure, so that the cable is not easy to slip off, and the defective rate is reduced; the assembling die is in a grid shape, the U-shaped grooves which correspond to each other in position can enable staggered parts of the upper die and the lower die to move up and down freely, so that the assembling die is suitable for assembling chucks of different sizes, the chucks can be bent into an annular shape by the U-shaped grooves, gaps between cables and the chucks are eliminated, the parts of the cables, which are exposed out of the insulating skins, are in full contact with the chucks, and the problem of poor contact is avoided; and meanwhile, the staggered parts of the upper and lower die grids generate shear stress during stamping, a plurality of stress concentration points appear on the chuck, and the stability of fixing the chuck is further improved.

Examples

As shown in figure 1, the terminal clamp comprises a bottom plate 1, two sides of the bottom plate 1 are bent to form side plates 2, and two anti-skidding teeth 3 are arranged on the side plates. The positions of the anti-skid teeth 3 correspond to each other, so that the anti-skid teeth 3 are staggered when the assembly is convenient, and the assembly firmness is improved; the bottom plate 1 is made of copper-plated iron, so that the conductivity of the chuck is ensured;

as shown in fig. 2-6, an assembly mold for a terminal clamp comprises an upper mold 4 and a lower mold 5, wherein a fixing rod 6 is arranged above the upper mold 4, and a base 7 is arranged below the lower mold 5, so that the mold is convenient to fix in use; the upper die 4 and the lower die 5 are both provided with U-shaped grooves, and the U-shaped grooves are in a grid shape.

Go up mould U type recess 8 and lower mould U type recess 10 and correspond the setting each other and go up mould U type recess grid 9 and the setting of staggering each other of lower mould U type recess grid 11 for go up the groove part of mould 4 and lower mould 5 and can coincide when the punching press, fully exert pressure to the wiring chuck, the staggered position of grid can produce stress concentration simultaneously, makes a plurality of stress concentration points on the chuck, further improves the fixed stability of chuck.

When the utility model is used, firstly, the die is fixed on the stamping equipment through the fixing rod 6 of the upper die 4 and the base 7 of the lower die 5, and the position is adjusted, so that the grids of the U-shaped groove parts correspond to each other, and the grids cannot collide when being opened and closed up and down; after a stamping equipment technical assembly mould is debugged, firstly, stripping an insulating skin at one end of a cable to be processed to expose a wire core therein, and then bending the wire core downwards until the wire core is tightly attached to the insulating skin; then, one end of the lower die, from which the insulation skin is stripped, is placed in the U-shaped groove of the lower die, the side plate of the jointing clamp head is placed on the cable downwards, the stamping device is driven to enable the upper die and the lower die to be closed, and the clamping head and the cable are stamped, so that the final effect is shown in fig. 7 and 8.

Comparative example
