Раскрытие предложения Offer Disclosure
Стыковой прессуемый зажим для контактных проводов содержит корпус 1 с пазами на внутренней поверхности и шпильку 2, при этом шпилька 2 размещена в пазах 3 корпуса 1 и пазах 4 контактного провода 5 , причем шпилька 2 имеет нарезку, длина которой соответствует длине корпуса 1 , а средняя часть шпильки 2 размещена в зоне стыка 6 контактных проводов. A press joint for contact wires contains a housing 1 with grooves on the inner surface and a stud 2, while the stud 2 is placed in the grooves 3 of the housing 1 and the grooves 4 of the contact wire 5, and the stud 2 has a thread, the length of which corresponds to the length of the housing 1, and the average part of the stud 2 is located in the joint zone 6 of the contact wires.
Площадь поперечного сечения корпуса 1 может превышать площадь сечения соединяемых проводов не менее чем в 2,5 раза, при этом длина корпуса находится в диапазоне от 100 мм до 180 мм. The cross-sectional area of the housing 1 may exceed the cross-sectional area of the connected wires by at least 2.5 times, while the length of the housing is in the range from 100 mm to 180 mm.
Шпилька 2 может быть изготовлена из нержавеющей стали или бронзы и имеет твердость, больше твердости контактного провода не менее чем в 1 ,6 раза и не более чем в 2 раза, диаметр шпильки составляет от Змм до 4 мм. Нарезка в шпильке 2 может иметь шаг от 1 мм до 1 , 5 мм, высоту гребня резьбы от 0,5 мм до 1 мм. Загнутая часть шпильки не имеет нарезки, она приподнята над контактным проводом, что исключает пробои этой части шпильки полозами токоприемников. Корпус 1 может быть выполнен из меди или бронзы. Корпус 1 в верхней части имеет отверстие 7 для размещения струны, которая поддерживает корпус зажима в верхнем положении и обеспечивает проход полозов токоприемника через стыковой зажим без ударов по зажиму. Stud 2 can be made of stainless steel or bronze and has a hardness greater than the hardness of the contact wire not less than 1, 6 times and not more than 2 times, the diameter of the stud is from Zmm to 4 mm. Cutting in the stud 2 may have a pitch of 1 mm to 1.5 mm, the height of the thread ridge from 0.5 mm to 1 mm. The bent part of the stud does not have cuts, it is raised above the contact wire, which eliminates breakdowns of this part of the stud with skids of current collectors. The housing 1 may be made of copper or bronze. The housing 1 in the upper part has an opening 7 for accommodating the string, which supports the clamp housing in the upper position and allows passage of the current collector skids through the butt clamp without impacts on the clamp.
При монтаже стыкового зажима шпилька 2 устанавливается в зоне стыка контактных проводов, причем середина шпильки 2 приходится на зону стыка контактных проводов в обхват малой головки контактного провода. На месте стыка 6 со шпилькой 2 монтируется корпус 1 зажима, после чего производится опрессовка корпуса стыкового зажима. В процессе опрессовки происходит внедрение резьбы шпильки 2 как в корпус 1 зажима, так и в контактный провод, за чет чего происходит надежное соединение концов контактного провода в стыковом зажиме. Прочность стыка должна быть не менее 0,9 от величины разрывной прочности соединяемых контактных проводов, при этом надежное зацепление зажима обеспечивается при проникновении нарезки шпильки в поверхностный слой контактных проводов. When installing the butt clamp, the pin 2 is installed in the joint zone of the contact wires, and the middle of the pin 2 is in the joint zone of the contact wires in the girth of the small head of the contact wire. At the junction 6 with the stud 2, the clamp body 1 is mounted, after which the butt clamp housing is crimped. In the process of crimping, the introduction of the threads of the stud 2 both in the housing 1 of the clamp and in the contact wire takes place, due to which there is a reliable connection of the ends of the contact wire in the butt clamp. The joint strength should be at least 0.9 of the tensile strength of the connected contact wires, while the reliable engagement of the clamp is ensured when the cutting of the stud penetrates the surface layer of the contact wires.
