(54) КОРОБ ДЛЯ ПРОВОДОВ(54) BOXES FOR WIRES

II

Изобретение относитс к электротехнике, а конкретно к коробу дл проводов.The invention relates to electrical engineering, and more specifically to a conduit box.

Известен короб дл проводов, содержащий пр мые секции с соединительными элементами (угловыми, тройниковыми, крестовыми ), в которые вход т пр мые секции 1. , Недостатком такого короба вл етс большое количество типов соединительных элементов.A conduit box is known, which contains straight sections with connecting elements (corner, tee, cross), which includes straight sections 1. The disadvantage of such a box is a large number of types of connecting elements.

Известен также короб дл проводов, содержащий пр мые секции н один тип соединительных элементов отводов и тройников , переходные детали (перекрутки) и накладные детали 2.Also known is a conduit box containing straight sections and one type of connecting elements for bends and tees, transitional parts (twists) and overhead parts 2.

Недостатком такого короба вл етс наличие переходных и накладных деталей, необходимых дл св зи пр мых секций с отводами и тройниками, что приводит к увеличению металлоемкости, а также трудозатрат при монтаже.The disadvantage of such a box is the presence of transitional and overhead parts required for the connection of straight sections with outlets and tees, which leads to an increase in metal consumption, as well as labor costs during installation.

Целью изобретени вл етс уменьшение металлоемкости короба дл проводов и тру дозатрат при его монтаже.The aim of the invention is to reduce the metal capacity of the conduit box and the labor costs during installation.

Поставленна цель достигаетс тем, что в коробе дл проводов, содержащем пр мые секции и соединительные элементы, в которые вход т концы пр мых секций, каждыйThis goal is achieved by the fact that in a conduit box containing straight sections and connecting elements, which include the ends of the straight sections, each

соединительный элемент выполнен разъемным по диагональной плоскости, боковые кра составл ющих его частей выполнены с отгибом наружу на угол 130-140°, при этом один из отгибов каждой части имеетthe connecting element is made detachable along a diagonal plane, the side edges of its component parts are made with a bend to the outside at an angle of 130-140 °, while one of the bends of each part has

На фиг. 1 изображен участок короба в сборе; на фиг. 2 - пр ма секци короба; на фиг. 3 - разрез А-А фиг. 1;FIG. 1 shows a section of the box assembly; in fig. 2 — straight box section; in fig. 3 - section A-A of FIG. one;

на фиг. 4 - общий вид отвода; на фиг. 5 - общий вид тройника; на фиг. 6 - элемент I фиг. 5.in fig. 4 - general view of the allotment; in fig. 5 - a general view of the tee; in fig. 6 - element I of FIG. five.

Короб состоит из пр мых секций 1, открытые стороны которых имеют съемные крыщки 2, снабженные отбортовками 3.The box consists of straight sections 1, the open sides of which have removable caps 2 fitted with flanges 3.

Пр мые секции имеют кра 4, форма.сечени которых позвол ет укрепить крыщки с секци ми заподлицо. Корпуса пр мых секций 1 соединены с соединительными элементами , выполненными из двух разъемныхThe straight sections have edges 4, the shape of which makes it possible to reinforce the lids with flush sections. Cases of straight sections 1 are connected to connecting elements made of two detachable

Claims

on the diagonal parts of the branches - the bottom 5 and top 6, the tees bottom 7 and top 8 parts. Each of the parts along the lateral edge is bent outward at an angle forming 130-140 °, with the walls of detachable parts, one of the bent edges 9 is straight and the other 10 is of a trough-shaped form. The lower parts of the taps or tees are fastened to the housings of the straight sections by welding, and the upper to the lower parts by means of a spring latch 11, which is located in the bend of a trough-shaped form. When assembling the duct for providing wiring in different directions, the straight sections 1 are installed in horizontal and vertical sections. In the horizontal sections, the straight sections 1 are set with their ends inside the taps and tees with the open side up, and on the vertical sections - the straight sections are rotated about the axis by 90 °, so that access is provided for the possibility of wiring. The lower parts 5 and 7 of the bends and tees are welded to the end sections of sections 1, and the upper 6 and 8 are covered with them. Interconnection of the upper 6 and 8 and lower 5 and 7 parts of the taps and tees is carried out using the latch 11. When vertically installing the taps and tees, they can have elements for fixing the wires Thanks to the location of the straight sections inside the taps and tees and making diagonally, it is possible to lay wires or cables without stretching with a smaller number of joints, which ensures a decrease in metal consumption and labor costs due to the absence of inserts, overlays and additional attachment points. Claims The box for wires containing straight sections and connecting elements, into which ends of straight sections are included, characterized in that, in order to reduce metal consumption and labor costs during installation, each connecting element is made detachable along a diagonal plane, the side edges of the components its parts are bent outward at an angle of 130-140 °, with one of the bends of each part having a trough-like shape and a locking element, for example a spring latch, is placed in it.
