INVENTOR.
Patented Jan. 23, 1951 CLAMPING DEVICE Boris Silbermann, Geneva, Switzerland Application March 13, 1946, Serial No. 654,039% In Switzerland December 27, 1944 6 Claims. 1
The present invention relates to clamping devices for cord-like members, and more particularly to clamping devices for securing a wire, cable or rope to a rigid body, such as a socket.
Still more particularly, the present invention relates to means for attaching electric wires or conductors to terminals.
It is an object of the present invention to provide clamping means for the above purposes which are extremely simple in construction, reliable in operation and inexpensive to produce.
The novel features which I consider as characteristic for my invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings, in which:
Fig. l is a partial longitudinal section through a clamping device according to the present invention;
Fig. 2 is a cross section through the clamping device shown in Fig. 1, along line 2-2 of Fig. l; and
Fig. 3 is a side view of the clamping device shown in Figures 1 and 2.
The clamping device shown in the drawing is used for securing the electric wire In to the terminal I I.
It includes as main elements a cylindrical member I2 which is provided with a longitudinal hole I3 adapted to receive the wire II! as clearly shown in Fig. 1.
The cylindrical member I2 is also provided with a transversal inclined slot I4 arranged in a plane enclosing an acute angle with the hole I3 so as to cross the hole as shown.
Furthermore, I provide a pin I5 freely movably arranged within the transversal inclined slot It so as to be movable in this slot between inoperative position located at the lower end of the slot and the operative position shown in Figure 1, pressing against the wire I and firmly holding the same in the hole I3.
In order to permanently force the pin I from its inoperative into operative position and to keep it in such operative position, I provide a guiding member such as the guiding ring or sleeve I6 surrounding the cylindrical member I2 and freely slidable in longitudinal direction of the same.
In this guiding sleeve, two opposite guiding slots II are provided; each of these slots has at least in transversal direction a greater length I5 against wire Ill, it is necessary to provide pressure means which permanently tend to move sleeve I6 indirection of arrow I9. These pressure means consist of spring 20 abutting at its upper end against the annular bottom face 2I of sleeve I6 and at its lower end against an annular projection 22 provided on the cylindrical member I2 as shown in Figure 1.
In order to obtain proper guidance for spring 20 and sleeve I6, I might provide the outer tubular enclosure member 23 which is arranged around the cylindrical member I2 spaced from the same as shown. This tubular enclosure member 23 might be made out of one piece with the cylindrical member I2 or it might be secured to the same at the bottom end of the cylindrical member in any desired manner.
1 wish to stress that in order to increase the gripping action of the pin I5 the same is preferably fluted as shown.
The entire device is assembled by first introducing the spring 20 into the annular space between the cylindrical member I2 and the tubular enclosure member 23, then placing the sleeve IS on the upper end of the spring and depressing the sleeve until the slots H in the same overlap with the inclined slot I4 in the cylindrical member I2. Then the pin I5 is introduced. After release of the sleeve I6, the constant pressure of spring 20 will keep the entire arrangement in assembled state.
If it is desired to clamp a wire to the terminal, the sleeve I6 is depressed against the direction of arrow I9, moving the pin I5 in the inclined slot I4 out of the hole I3 and thus permitting introduction of the wire I0. After introduction of the wire, the sleeve I6 is' released and the action of spring 20 pushes the sleeve IS in direction of arrow I9. The sleeve IS in turn forces by means of the slots I'I thepin I5 to slide in the inclined slot I4 against the wire III, firmly clamping the same in the hole I3.
I wish to stress that although I have described above the new clamping device invented by me as used for securing an electric wire to a terminal, such clamping devices may be used for many other purposes.
