Utility model

Electrical Lgij? Ijmggfclemme, especially pulls! Clamp ₀

y. The innovation relates to an electrical cable clamp

S aua sheet metal bent clamp, encompassing a contact bar

bracket (tension bracket clamp), the overlapping ends of which have a through hole for a clamping screw? the threaded bolt of which engages in a nut guided in a torsion-proof manner inside the clamping bracket, as well as with a fixed contact rail, to which the clamping bracket can slide perpendicularly ₀

It has already been suggested for clamps of this type * the sliding of the clamping bracket off the contact rail

thereby prevent au and still the mobility of the clamping bracket with respect to the. To get contact _{bar $} that in one leg of the clamping bracket an elongated hole is worked into which a pin attached to one side surface of the contact ". Seemed ©" engages with play.

Output of the controller, it is now * such a terminal to comparable Γ '' beasern * The one-sided guidance of the clamp it koante namely happen "that when tightening the clamping screw the whole clamp around the Klemmschraibenachse result of the game between the contact rail and clamp a rotary ™ movement and thereby the fixed pin jammed in the Schiita, whereby the clamping bracket sliding movement was secret »Furthermore, the drilling of the hole required for

Put on the contact rail of the clamp and by means of the To attach the pin 'to the contact rail and then se on the insulator

'The jamming of the clamping bracket becomes weird as a result prevents that in both legs of the clamping bracket; one each Long hole incorporated is the relatively cumbersome

Drilling, · the insertion of the bracket, turning of the pin and fixed in the insulating body, but is considerably simplified and thus less expensive, that the contact rail is subjected to a short pressing operation * being expressed on each narrow side, wherein feed-through terminals at both ends of the contact rail _t short approaches \
■ * werdeno There is no drilling, pen or handling

r -'- this small part for the purpose of assembly ₀ The contact rail with the expressed approaches v & rd fastened to the insulating body and the clamping bracket (s) simply slipped onto the contact rail at an angle and erected with temporary tension so that the expressed approaches into the guide slots engage the two legs of the clamp,

The object of the innovation is to be found in the attached Drawing explained in more detail in the

As can be seen from the figures, it is made of sheet metal

The 'clamping screw 5 is threaded in a nut guided in the clamp loosely but not rotatable above "

The line end to be connected to the contact rail 4 (Figo, 2) is turned back or turned up 20. Clamping screw 5 inserted into the clamping bracket 1 below the contact rail 4 »When tightening the clamping screw 5 presses its lower end onto the contact rail 4, so that the clamping bracket 1 is pulled upwards and that
