England Applicationi-Mayi'm, 1946;, Serial N 0,669,760 In Great Britain May- 30; 1945 1 Claim. 1;:
This invention relates tosupports' rorelectric' conductors such as bus bars and cables. Such supports are usually made of insulating material and comprise two main members which can be drawn together to grip the conductor which passes between them. Owing to the fact that a number of different cross-sectional shapes are employed for the conductors, and also a large range of different sizes, it has hitherto been necessary to make a large range of insulating supports with the conductor-gripping parts of different shapes and sizes.
The object of the present invention is to provide a support for electric conductors which can be used for a number of different cross-sectional shapes of conductors and a number of different slzes.
A support constructed in accordance with the present invention comprises two members which can be secured to a suitable support and which can be drawn together to grip a conductor which passes between them, the gripping surface of one or both members being shaped to provide a slot, the inner portion of which is of substantially rectangular section and the outer portion of which provides two diverging surfaces. The two members provide opposed gripping surfaces suitable for conductors of rectangular, square or circular section.
The surfaces of one of the two members adjacent the open ends of the slots may be stepped or shouldered, the steps or shoulders being adapted to engage opposite edges of conductors of rectangular section.
One member may be formed as a block of insulating material and the other member may be formed as a cap of insulating material adapted to be drawn by screws onto the top of the block, and the cap may have portions of channel section, the sides of the channels engaging over opposite end faces of the block so that the shanks of the screws are completely shrouded or enclosed.
The invention is illustrated in the accompanying drawings, wherein:
Figure 1 is a view in front elevation showing three of the supports mounted on a suitable bracket;
Figure 2 is a sectional view in front elevation showing one of the supports; and
Figure 3 is a perspective view showing the two main parts separately; Figures 2 and 3 being drawn to a larger scale than Figure 1.
In the construction illustrated the block I'll may be produced as a moulding of porcelain,
synthetic resin or other insulating material, and
it is provided with two end portions II in each of which is a cavity l2 of square, hexagonalo'r' other nonacircular section forreceiving a nut" I 3, and the arrangementissuch that the block can be secured to a suitable support M by screws l-5 passed through the support and into the end portions of the block and into the nuts l3.
The cap member [6 at its ends I! is of channel section, and the sides of these channels engage over and slide upon the sides of the end portions ll of the block. The cap member is provided with screw holes [8 at the top so that screws I9 may be passed through it and downwardly into the upper ends of the nuts l3.
The gripping portions of the two members are somewhat longer than the distance between the faces 20 of the main portions of the two members so that they project from opposite faces thereof. Each of the gripping portions is provided with a slot 2 l, the inner portion of which is approximately of square or other rectangular section, and the outer portion of which provides two diverging surfaces 23 which are at an obtuse angle, or may be approximately at right-angles to each other.
The underside of the cap may be stepped upwardly at 24 on either side of the slot, and the upper side of the gripping portion of the block or lower member may be similarly stepped at 25.
The insulating support thus constructed is suitable for gripping circular-section conductors between the four diverging surfaces of the gripping portions, and it is also suitable for gripping conductors of rectangular section with the major dimension either horizontal or vertical, as shown in Figure 1. Such conductors may also be of varying widths.
When the appliance is used to grip a square conductor, this may be placed with the diagonals of its section vertical and horizontal so that the conductor is gripped by the diverging surfaces 23. For conductors of rectangular section but varying thicknesses, packing pieces may be used between one side of the conductor and one side of the gripping surface of the support.
The support may be of course made in a range of sizes, and a single support may be constructed with two or more pairs of gripping surfaces for supporting and gripping a plurality of conductors.
What we claim then is:
A support for electric conductors comprising a block and a cap forming conductor-gripping members, the block having end portions in each of which i a cavity, the cap having end por- 3 tions of channel form the sides of the channels engaging the outer surfaces of the sides of the end portions of the block, a nut housed in each said cavity, screws extending through the end portions of said block and engaging one end of each nut, and further screws extending through the end portions of said cap and engaging the 0P- posite end of each nut, said block and said cap having conductor engaging surfaces, the conductor engaging surface of said block being formed as a substantially rectangular slot the outer sides of which form two diverging surfaces whose outer edges terminate in upwardly directed rightangle steps, the conductor-engaging surfaces of the cap being formed as a substantially rectangular slot the outer sides of which form two diverging surfaces whose outer edges terminate in right-angle shoulders adapted to fit within the aforementioned steps whereby conductors of different sizes and cross-section may be positively located between the cap and the block, and may be positively located during assembly of said support.
