Description
Универсальный безболтовой соединительный зажим Universal Boltless Connection Clamp
Область техники Technical field
Предложение относится к электрофицированному железнодорожному транспорту и направлено на усовершенствование зажимов для соединение проводов контактной сети. The proposal relates to electrified railway transport and is aimed at improving clamps for connecting wires of the contact network.
Предшествующий уровень техники State of the art
Известен безболтовой соединительный зажим для проводов, содержащий корпус S-образной формы (см. SU 1315348 А1 , 07.06.1987). Known bolt-free connecting clip for wires containing an S-shaped housing (see SU 1315348 A1, 06/07/1987).
Недостатками прототипа являются: The disadvantages of the prototype are:
1) Нестабильное обжатие верхней части прессуемого зажима с несущим многопроволочным проводом, вследствие чего может иметь место недостаточно надежный электрический контакт между проводом и зажимом из-за неплотного прилегания поверхности зажима к нижней части многопроволочного провода. 1) Unstable squeezing of the upper part of the pressed clamp with the supporting multi-wire wire, as a result of which there may be insufficiently reliable electrical contact between the wire and the clamp due to the loose surface of the clamp to the lower part of the multi-wire wire.
2) Из-за причин в п.1 снижается допустимая токовая нагрузка зажима, для восстановления которой необходимо увеличивать ширину зажима, вследствие чего возрастает в 2-4 раза время опрессовки. 2) Due to the reasons in paragraph 1, the allowable current load of the clamp is reduced, to restore which it is necessary to increase the width of the clamp, as a result of which the crimping time increases 2-4 times.
3) При указанной конфигурации зажима нет критерия окончания процесса опрессовки, что не может гарантировать недопрессовку зажима и в процессе эксплуатации нарушение качества электрического контакта между проводом и зажимом. 3) With the specified clamp configuration, there is no criterion for the end of the crimping process, which cannot guarantee underpressing of the clamp and, during operation, a violation of the quality of the electrical contact between the wire and the clamp.
Раскрытие предложения Offer Disclosure
Техническим результатом предложения является: The technical result of the proposal is:
- наличие выступа на верхней части края верхней полки зажима позволяет при помощи пресса и соответствующей конструкции оснастки производить не только качественную опрессовку зажима на проводе, но и запрессовывать указанный выступ в зону между нижней частью верхнего провода (например, несущего троса цепной подвески) и средней частью зажима, что улучшает качество электрического контакта между проводом
и зажимом и, в свою очередь, увеличивает токовую нагрузочную способность последнего; - the presence of a protrusion on the upper part of the edge of the upper flange of the clamp allows using a press and an appropriate tooling to produce not only high-quality crimping of the clamp on the wire, but also to press the specified protrusion into the area between the lower part of the upper wire (for example, the bearing cable of the chain suspension) and the middle part clamp, which improves the quality of the electrical contact between the wire and clamp and, in turn, increases the current load capacity of the latter;
- для надежного соединения прессуемого зажима и многопроволочного провода поперечное сечение зажима должно превышать сечение соединительных проводов в 3 раза и более; - for a reliable connection of the pressed clamp and the multiwire wire, the cross section of the clamp must exceed the cross section of the connecting wires by 3 times or more;
- для обеспечения надежного соединения двух проводов в зажиме его вертикальная опорная стенка должна иметь толщину от 5 мм до 7 мм; - to ensure a reliable connection of two wires in the clamp, its vertical supporting wall should have a thickness of 5 mm to 7 mm;
-для удобства работ и сокращения времени монтажа зажима его нижняя часть, предназначенная для крепления его на проводе неограниченной длинны выполнен участок под углом под углом от 15° до 30° к горизонтали длиной от 5 мм до 10 мм; - for the convenience of work and reducing the time of installation of the clamp, its lower part, intended for mounting it on a wire of unlimited length, made a section at an angle from 15 ° to 30 ° to a horizontal length of 5 mm to 10 mm;
- в процессе опресовки время завершения монтажа зажимов при различном сортаменте проводов составляет всего 13 - 19 с, что значительно меньше времени монтажа известных зажимов. - in the process of pressure testing, the time for completing the installation of clamps with a different assortment of wires is only 13 - 19 s, which is significantly less than the installation time of known clamps.
Технический результат достигается тем, что безболтовой соединительный зажим содержит корпус, в верхней части которого выполнена открытая полость для размещения в ней провода неограниченной длины, в нижней части корпуса выполнено отверстие с прорезью для размещения в нем провода ограниченной длины, при этом площадь поперечного сечения зажима превышает не менее чем в 3 раза площадь поперечного сечения соединяемых в зажиме проводов, причем в нижней части корпуса для размещения в ней провода ограниченной длины выполнен участок длиной от 5 мм до 10 мм под углом от 15° до 30° к горизонтали, а на верхней части края верхней полки зажима выполнен выступ. The technical result is achieved by the fact that the bolt-free connecting clip contains a housing, in the upper part of which an open cavity is made to accommodate wires of unlimited length, a hole with a slot is made in the lower part of the housing to accommodate wires of limited length, while the cross-sectional area of the clamp exceeds not less than 3 times the cross-sectional area of the wires connected in the clamp, and in the lower part of the housing for placing wires of limited length in it, a section of length from 5 m to 10 mm at an angle of 15 ° to 30 ° to the horizontal and at the top edge of the upper clamping flange projection is formed.

Варианты осуществления предложения Options for implementing the proposal
Безболтовой соединительный прессуемый зажим для проводов содержит корпус 1, в верхней части которого выполнена открытая полость 2 для размещения в ней провода неограниченной длины, в нижней части корпуса выполнено отверстие 5 с прорезью 6 для размещения в нем провода ограниченной длины, при этом на кромке 3 верхней части полости выполнен выступ 4 по всей ширине зажима. В нижней части корпуса для размещения в ней провода неограниченной длины выполнен участок 9 длиной от 5 мм до 10 мм под углом а от 15° до 30° к горизонтали A bolt-free, extrudable clamp for wires contains a housing 1, in the upper part of which an open cavity 2 is made to accommodate wires of unlimited length, a hole 5 is made in the lower part of the housing with a slot 6 to accommodate a wire of limited length, while on the edge 3 of the upper part of the cavity, a protrusion 4 is made over the entire width of the clamp. In the lower part of the housing for placing wires of unlimited length in it, a section 9 is made with a length of 5 mm to 10 mm at an angle a from 15 ° to 30 ° to the horizontal
Величина высоты выступа составляет от 2 до 6 мм в зависимости от диаметра соединяемого провода, а величина высоты прорези соответствует 0,3-0,4 диаметра провода ограниченной длины. The height of the protrusion is from 2 to 6 mm, depending on the diameter of the connected wire, and the height of the slot corresponds to 0.3-0.4 diameter wire of limited length.
Для возможности осуществления плотного контакта прессуемого зажима с проводом неограниченной длины на верхней части полости зажима имеется выступ 4, в который в процессе опрессовки упирается матрица 7, размещенная в силовой головке пресса, и заворачивает верхнюю часть полости консольной части зажима вокруг провода неограниченной длины, процесс опрессовки происходит до схождения края полости с корпусом зажима. Для опрессовки зажима использован пуансон 8. To enable tight clamping of the pressed clamp with a wire of unlimited length, there is a protrusion 4 on the upper part of the clamp cavity, into which the die 7 rests in the power head of the press, and wraps the upper part of the cavity of the cantilever part of the clamp around the wire of unlimited length, the crimping process occurs until the edge of the cavity converges with the clamp body. For crimping the clamp, a punch 8 is used.
В нижней части зажима имеется прорезь, расположенная в горизонтальной плоскости зажима, которая позволяет произвести опрессовку соединительного зажима вплоть до схождения краев прорези, при этом происходит опрессовка в зажиме проводов как неограниченной, так и ограниченной длины. In the lower part of the clamp there is a slot located in the horizontal plane of the clamp, which allows crimping the connection clamp up to the convergence of the edges of the slot, while crimping in the clamp of wires of both unlimited and limited length.
Размер прорези в прессуемом зажиме зависит от диаметра провода ограниченной длины и позволяет определить при схождении его краев в процессе опрессовки момент завершения прессования.
Время монтажа предложенного зажима сокращается до 12-19 с, что в несколько раз превышает время монтажа известных зажимов. The size of the slot in the pressed clamp depends on the diameter of the wire of limited length and allows you to determine when the edges converge during the crimping process when the pressing is completed. The mounting time of the proposed clamp is reduced to 12-19 s, which is several times longer than the mounting time of known clamps.
