Description

Aluminium alloy cable earth connection terminal crimping mold

Technical field

The utility model relates to crimp, particularly the crimp of aluminium alloy cable binding post.

Background technology

In power industry, people use in crimp cooperation Press Plier this construction of online roadbed and line maintenance and carry out wire-connection crimping.Specifically, supply line to be connected, need copper, aluminium, aluminium alloy cable and cable terminal to carry out crimping to be mechanically connected with facilities such as switch bronze medals again, when cable and cable terminal crimp, the shape that the alteration of form of terminal is reached by hydraulic pressure or mechanical pressure by crimp required for crimp, cable is firmly connected with cable terminal, then the cable connected and cable terminal are connected on the equipment such as distribution and electricity consumption.

Traditional crimp generally considers the size of copper core cable binding post in design, is not suitable for the processing of aluminium alloy cable binding post.

The binding post using traditional crimp to produce, often with overlap, need carry out the polishing processing of follow-up removal overlap.Secondly, the width of traditional crimp is too narrow, and as width is not more than 11mm, if be applied on aluminium cable and aluminium alloy cable, cable is too little with binding post contact-making surface, and current capacity is just on the low side.

Utility model content

The purpose of this utility model is to provide a kind of aluminium alloy cable earth connection terminal crimping mold, to make the easy demoulding of binding post after crimping and non-trimming.

The purpose of this utility model is achieved in that a kind of aluminium alloy cable earth connection terminal crimping mold, be made up of mold and bed die, described mold and bed die symmetrical shape, during this upper and lower mould matched moulds, the upper half bore of mold and the lower half bore of bed die are spliced into a regular hexagon hole: the upper half bore of this mold is the isosceles trapezoid perforate of a base opening, and two of this isosceles trapezoid drift angles are rounding R1, outside two extended lines on the base of this isosceles trapezoid are rounding R2 with the angle between corresponding waist respectively.

R1 in the upper half bore of described mold is 1.8mm ~ 3mm, R2 is 1.8mm.

The top surface being parallel of described mold is in the upper bottom surface of its isosceles trapezoid perforate, the left and right side be parallel to each other of mold is all perpendicular to the upper bottom surface of its isosceles trapezoid perforate, and the forward and backward position of the left and right side of mold is all processed with for the fixing step of fixture.

The long L of the end face of described mold is 34 ± 1mm, and the wide W2 of this end face is 13mm ~ 18mm, and the high H of the left and right side of this mold is 18 ± 0.5mm.

The length L1 of base after rounding R2 of isosceles trapezoid perforate in described mold is 28 ± 0.5mm.

The length of bench of described mold is 3mm, and width is 2mm ~ 7mm.

The conductor nominal cross being mm2 in the unit of aluminium alloy cable is: 16,25,35,50,70,95,120,150, when 185, the unit in the regular hexagon hole that described upper and lower mould (1,2) is spliced into is that the length of side B of mm corresponds to respectively: 5 ± 0.3,5.75 ± 0.3,6.75 ± 0.3,7.75 ± 0.3,8.65 ± 0.3,10.25 ± 0.3,11 ± 0.3,12.25 ± 0.3,13 ± 0.3, mold unit is that the wide W2 of the end face of mm corresponds to respectively: 13 ± 1,14 ± 1,16 ± 1,18 ± 1,13 ± 1,15 ± 1,15 ± 1,15 ± 1,15 ± 1.

Compared with prior art, the beneficial effects of the utility model are:

1, because mould (being made up of upper and lower mould) hollow part and regular hexagon perforate add the rounding process of R1 and R2, make to crimp the binding post non-trimming (due to the effect of R1 rounding) processed and obtain, and due to R2 rounding, binding post after crimping is more easily separated with upper and lower mould, i.e. the easier demoulding.

2, the width (in Fig. 3 W2) of original mould is only 11mm, and the width of this mould is increased to 13mm ~ 18mm, and arranges step on upper and lower mould, and fixture of being more convenient for is fixed, and is conducive to the crimping process operation of press equipment.

3, the utility model is exclusively used in the processing of aluminium alloy cable binding post, add man-hour, consider this mould hollow part area, make compression ratio control between 10% ~ 18%, contact reliable to ensure binding post firmly to connect with cable, and crimping place contact resistance can not sharply rise.Tradition crimp compression ratio is greater than 18%, presses to obtain tension, causes crimping place contact resistance sharply to raise, bring potential safety hazard to the application of aluminium alloy cable, as crimping place abnormal heating during transmission of electricity, causes mechanical strength to reduce, shortening cable useful life.

Embodiment

Fig. 1 illustrates this crimp, mold 1 and bed die 2 symmetrical shape, when this upper and lower mould 1,2-in-1 mould, the upper half bore of mold 1 and the lower half bore of bed die 2 are spliced into a regular hexagon hole: the upper half bore of this mold 1 is the isosceles trapezoid perforate of a base opening, and two of this isosceles trapezoid drift angles are rounding R1, outside two extended lines on the base of this isosceles trapezoid are rounding R2 with the angle between corresponding waist respectively.In Fig. 1, mold and bed die symmetrical shape (from another angle, the mold after taking apart is all identical with structure with the shape of bed die).See Fig. 2, the lower half bore of bed die is similarly an isosceles trapezoid perforate.Two drift angles of this isosceles trapezoid are 120 °, i.e. the angle on the hexagonal adjacent both sides of Zheng.See Fig. 3, the R1 in the upper half bore of mold 1 is 1.8mm ~ 3mm, R2 is 1.8mm.The top surface being parallel of mold 1 is in the upper bottom surface of its isosceles trapezoid perforate, all perpendicular to the upper bottom surface of its isosceles trapezoid perforate, (leading flank of mold is parallel with trailing flank for the left and right side be parallel to each other of mold 1, and the two is all perpendicular to the end face of mold, the bottom surface of mold is parallel to the end face of mold), and the forward and backward position of the left and right side of mold 1 is all processed with for the fixing step of fixture.The length of bench of mold 1 is 3mm, and width is 2mm ~ 7mm.The long L of the end face of mold 1 is 34 ± 1mm, and the wide W2 of this end face is 13mm ~ 18mm, and the high H of the left and right side of this mold is 18 ± 0.5mm.The length L1 of base after rounding R2 of isosceles trapezoid perforate in mold 1 is 28 ± 0.5mm.In Fig. 2, the length of L1 is: between the extended line left on the base of isosceles trapezoid perforate in mold and left waist, reciprocal radius is 1.8mm(and R2) fillet, and the base of this isosceles trapezoid perforate to the right between extended line and right waist reciprocal radius be the fillet of 1.8mm, and be only limitted to the length (not comprising the length of the straight line portion after rounding) between two rounding places.

As shown in Figure 1, this crimp is made up of upper and lower mould two parts, and upper and lower mold shape is in the same size, and can be separated.During use, upper and lower mould part is put into Crimping Pliers two ends respectively, then binding post blank and cable end are put into mould hollow part crimp.In Fig. 1, S part is hollow out, through calculating, S portion size has two kinds of series, can meet a crimping of GB copper-aluminum transition terminal DTL, another kind can meet the crimping of import copper-aluminum transition terminal, two kinds of corresponding serial dies of serial terminal applications, the compression ratio of crimping is between 10%-18%, and non-trimming, crimping effect is good, by the binding post reliable in quality after the crimping of this mould.
