Abstract
The invention provides a lead crimping tube and relates to a lead link fitting. The lead crimping tube has advantages of high connection reliability and good effect. The lead crimping tube is characterized in that: tapering is formed respectively at outer surfaces of orifices of two ends of the tube; the internal diameter of the tube is larger than 1 to 5% of the external diameter of the lead; and a ratio of the internal diameter of the tube to the length of the tube is 1 to 5-20. According to the invention, in order to avoid an occurrence of a corona phenomenon at a step between a crimping tube and a lead after the crimping, outer surfaces of orifices of the crimping tube are arranged in a tapering mode; and an optimally selected mode is as follows: the mode of transition to an inner bore edge of the tube is arranged into a curved one. In addition, with regard to an occurrence of a steel-cored aluminium strand product, a connecting tube is added; crimping and connection are carried out on the steel core and then crimping is carried out on the aluminium stranded wire; therefore, a main stretching load is exerted on the steel core and it is avoided the aluminium stranded wire for power transmission is stretched too much. Moreover, the lead crimping tube has high connection reliability and a good conducting effect is realized after the connection.
Description
Technical field
The present invention relates to a kind of lead gold utensil that continues, particularly a kind of preformed lead splicing sleeve strengthens splicing sleeve.
Background technology
Using the very huge aluminium hydraulic pressed connecting pipe of number on the power overhead network, adopting hydraulic pressure or pincers to press technology, layering continues respectively to the steel core part and the aluminium lamination part of steel reinforced aluminium conductor.The version of lead variation at present has common aluminium stranded conductor, has the aluminium stranded conductor of steel core in addition.Especially the latter adopts common aluminium hydraulic pressed connecting pipe, because steel core is different with the yield strength of aluminium stranded conductor, can make that crimping stress is variant, and the effect that causes continuing is bad.
Summary of the invention
The present invention is directed to above problem, a kind of reliability height that continues is provided, effective conductor compression jointing pipe.
Technical scheme of the present invention is: the outer surface of the said pipe two ends mouth of pipe is provided with tapering.
The internal diameter of said pipe is greater than said wire diameter 1-5%, and the internal diameter of said pipe and the length ratio of pipe are 1: 5-20.
Said lead is provided with steel core, in said pipe, also is provided with splicing sleeve, and said splicing sleeve internal diameter is greater than said steel core external diameter 1-5%.
The present invention avoids that corona phenomenon appears in the step between the aluminium hydraulic pressed connecting pipe and lead after the crimping, and aluminium hydraulic pressed connecting pipe mouth of pipe outer surface is set to taper, and optimal way is the interior peritreme of arc-shaped transition to pipe.In addition, to the present steel reinforced aluminium conductor product that occurred, the present invention has set up a splicing sleeve; It carries out crimping with steel core and continues; And then aluminium stranded conductor integral body carried out crimping, and main tensile load is acted on the steel core, avoided the aluminium stranded conductor of transferring electric power task excessively to be stretched.The reliability height that continues of the present invention, after continuing, conductive effect is good.

Embodiment
The present invention is shown in Fig. 1-7, and the outer surface of the aluminium hydraulic pressed connecting pipe 1 two ends mouth of pipe is provided with tapering 10.
The internal diameter of aluminium hydraulic pressed connecting pipe 1 is greater than lead (among Fig. 2 among steel reinforced aluminium conductor or Fig. 6 aluminium stranded conductor 4) external diameter 1-5%, and the length ratio of the internal diameter of aluminium hydraulic pressed connecting pipe 1 and aluminium hydraulic pressed connecting pipe 1 is 1: 5-20.
Be provided with steel core 30 (promptly like the steel reinforced aluminium conductor among Fig. 2) in the lead, the outside is an aluminium stranded conductor layer 3, in aluminium hydraulic pressed connecting pipe 1, also is provided with splicing sleeve 2, and splicing sleeve 2 internal diameters are greater than steel core 30 external diameter 1-5%.
