WITH

The invention relates to radio engineering and can be used in various radio engineering devices and communication equipment, in particular for connecting conductive conductors of various telephone devices and apparatuses.

The purpose of the invention is to simplify the design and reduce the complexity of manufacturing.

This goal is achieved by the fact that in the clamp for screwless connection of the wire, the wall of the support element is provided with a window restricting the movement of the elastic element and holding it in the tension state, and the elastic element is provided with coaxial holes interacting when the wire is fixed with the window of the wall of the support element, and also the fact that the elastic and supporting elements are made in the form of one part, in which the functions

the supporting element performs the base of the elastic element.

Comparative analysis with the prototype shows that the clamp is characterized in that the wall of the supporting element is provided with a window restricting the movement of the elastic element and holding it in a stressed state, the elastic element is equipped with coaxial holes interacting when the wire is fixed with the window of the wall of the supporting element and the fact that the elastic and supporting elements are made in the form of one part, in which the base of the elastic element performs the functions of the supporting element.

Fig. 1 shows a clamp in its initial state; figure 2 - clip with a connected wire; Fig. 3-control element; figure 4 - contact element; Figures 5 and 6 show clamping options (contact element) in the initial unstressed state.

The clamp contains a control element 1 made of insulating material and a contact element 2 made in the form of a curved part from a sheet of elastic conductive material and, in turn, consisting of a base 3 with a bend in the form of a wall 4 with a rectangular window 5 and a console 6 with a limb of the end portion 7 and having openings 8 and 9 for introducing a wire, such that the width of the cantilever 6 (size A) is less than the width of the window 5 (size B). The cantilever 6 in the stressed state is led by the bend 7 to the window 5 so that the bend 7 is on the outside of the bend in the form of a wall 4. In this case, the window 5 should be designed so that it is possible to move the cantilever 6 towards the more stressed state but, movement towards the less stressed state of the console 6. should be fixed by the top edge of the window 5.

The control element 1 is fixed to the contact element 2, for example, by means of the elements 10 and can be provided with a groove 11 for easy entry of the wire. When installing the clamp in the apparatus, it is fastened, for example, through holes 12, 13.

When connecting the wire 14, they press the control element 1, which transfers the applied force of the console 6, driving the latter to an even more stressed state. After aligning the holes 8 and 9 with the window 5, wire 14 is inserted through the groove 11, the hole 8, the window 5 and the hole 9. then the force is removed. The console 6, trying to take a less stressed state, presses the wire 14 against the upper edge of the window 5.

The presence in the wall of the supporting element of the window, restricting movement and holding the cantilever (elastic element) in tension, as well as the presence of

in the latter, coaxial holes interacting when fixing the wire with the window of the wall of the supporting element and, in turn, combining the functions of the elastic and supporting element in one part having a simple geometric configuration, greatly simplifies the design, which leads to a significant reduction in the costs associated with the manufacture of the clamp. Thus, the use of the claimed invention will significantly simplify the design, as well as reduce manufacturing costs by approximately 2.5 times.
