    Contact device operates as follows.
    In the initial position, the rulers 18 and 19 occupy a position (Fig. 1), in which on one side the axis 23 is located on the bottom of the inclined parts 20-1 of the guide figure grooves 20 and connected to the combs 12 and 13, and on the other axis 25 are located at the bottom of the parallel parts 21-2 of the guide shaped grooves 21 and are fixed to the flanges 22. With such an arrangement of the said axes 23 and 25, prior to the introduction of the PCB 2, the combs 12 and 13 are in the most distant position from the inner part of the frame 1 (Fig. 5), in this case for each elastic contact element 3 e between its support section 3-3 and its support end 3-6 is minimally the top of its A-shaped active part.4, therefore, it is as far as possible from the bottom 31-1 of groove 21 and protrudes in relation to the plane of the projections 32 of any of A comb 12 or 13 in which said elastic contact element 3 is placed. For the above reasons, it is dangerous to insert a printed circuit board 2 between combs 12 and 13 opposite one another, as damage to the elastic contact elements 3 may occur, however the flanges 22 are in their own n and a more approximate position to the inside of the frame 1, between the outer edges 34-1 of the grooves 34 of the two opposite flanges 2, there is a gap smaller than the width of the printed circuit board 2, therefore the printed circuit board 2 cannot be installed into the device, by moving the levers 27 in the direction of the arrows (FIG. 1) or when exposed to any other similar control, it is necessary to first move the rulers 18 and 19 along the indicated arrow in the direction of frame 1 to a position where the axes 23 and 25 will occupy other extreme positions, respectively, in the guide grooves 20 and 21 (Fig 4), namely, the axles 23 will occupy an extreme position in the parallel parts 20 in the guide figure grooves 20, and the axis 25 in the inclined parts 21-1 of the guide figure grooves 21, during the indicated movement, first the axis 25 passes t along parallel parts 21 in the direction of their shaped grooves 21, so that the flanges 22 remain stationary at the same time, the axes 23 pass along the inclined parts 20-1 of the guide shaped grooves 20, as a result of which the combs 12 and 13 move to the inside of the frame 1. Thus the combs 12 and 13 move And take a position in which the L-shaped active parts 4 of the elastic contact elements do not extend beyond the plane of placement of the protrusions 32 of the combs 12 and 13, since the distance between its support section 3-3 and the support end 3-6 max slalom , while the elastic contact element is open During the further movement of the rulers 18 and 19, the axis 23 passes along parallel parts 20-2 of the guide figure grooves 20, as a result of which the combs 12 and 13 remain stationary, while the axis 25 passes along the inclined parts 21-1 of the guide grooves 21, as a result of which the flanges 22 occupy their position, the most distant from the center of the frame 1, after which the printed circuit board 2 is installed in the guide grooves 34 of the flanges 22, which is facilitated by the fact that the guide grooves 34 are made with rounded edges 34-1, 34-2 34-3 (FIG. 3), as a result of which the printed circuit board 2 occupies its initial half-height (Fig. 1). Further, the operator moves the levers 27 and in the direction opposite to the direction of the arrows (FIG. 1K, as a result of this, the same movements occur as described, but in reverse order and direction, i.e., the flanges 22 move towards each other relative to the other, thereby blocking the printed circuit board 2, which has for this purpose grooves 35 (FIG. 1) in which the flanges 22 are placed as a result of movement indicated above, when locked, then the combs 12 and 13 are retracted from the center of the frame 1, while the elastic contact elements 3 with their L-shaped active and parts 4 extend beyond, the plane of measuring the projections 32, and the vertices of the L-shaped active parts 4 are closed with conductive connecting paths 5 of the printed circuit board 2, thus the elastic contact elements 3 are closed with an elastic force which determined by the geometric and elastic characteristics and the stroke of the movement of the dies 12 and 13. For the subsequent removal of the PCB 2, operations are performed on opening the elastic contact elements 3, namely the levers 27 are turned in the direction indicated by the arrow s, the movement of 12 and 13 takes place in the direction from the center of the printed circuit board 2, while the elastic contact elements 3 are located completely with their L-shaped active parts 4 in the slots 31 of the combs 12 and 13, coming out of contact with the conductive connecting tracks 5 of the printed the boards 2, the flanges 22 move apart and the PCB 2 is unlocked, which in this position can be removed from the contact device. When contacting and moving the vertices of the L-shaped active parts 4 of the elastic contact elements 3, the conductive connecting tracks 5 of the printed circuit boards 2 are automatically cleaned. When one of the combs, for example, the comb 12, is moved from a partially open elastic element 3 (Fig. 6) in the position of a closed elastic contact element 3 (Fig. 7). The length of the l-shaped active part 4 is reduced by magnitude. L to a smaller magnitude B, and the height of the l-shaped active part 4 increases from h to a larger value H, this increase in the height of the l-shaped active part 4 first brings the apex of the l-shaped active part 4 into contact with the conductive connecting path 5 of the printed circuit board 2, which corresponds to the given elastic contact element 3, then moving this vertex of the l-shaped active part 4 relative to the corresponding conductive connecting track 5 of the printed circuit board 2, accompanied by an increase in the pressure of the elastic of the contact element 3, ensures the cleaning of the conductive connecting track 5, this is due to the fact that the closed loop of the support section 3-3 (FIGS. 6 and 7) is pressed against the wall under the influence of pressure from branch 3-4. the groove 11 of the housing 10, the passage from the opening position to the closing position, increasing in diameter, while the branch 3-4 is shortened, which allows the branches 3-5, ending with the support end 3-6, rigidly fixed in the support slot 33, move virtually no deformation, i.e. allows the top of the l-shaped active part 4 to clear the conductive connecting track 5 of the printed circuit board 2 at a distance B. In order to facilitate the deformation of the closed loop of the support section 3-3, it is preferable not to press it against the comb 12. Other embodiments of the individual parts of the elastic contact elements are preferable for other operating conditions at high frequency currents. So, when an elastic contact element 3 is made in the form of a wire element 43 (FIG. 8), its supporting section 43-1 is made in the form of an arc, bending of elasticity, at the level of this section 43 in the groove 10 a supporting groove 30 is made, perpendicularly grooved 15 so that the bends of elasticity 43-1 do not touch the body 10 and do not lose their deformation freedom in the same way for the same reasons, the branch 43-6 remains at a distance from the bottom 31-1 of the groove 31 of the comb 12, this support end 42-2 is rigidly fixed in the support socket 33, executed in the comb 12, e If it is not foreseen to replace the elastic contact element 43 during operation, it is possible to fix its support end 43-2 by welding, for which support seat 33 is metallized or otherwise embedded in the edge of the comb 12. In accordance with the design of the elastic contact member 3 in the form of wire round section (fig. 9) with a support end 3-6, made in the form of successively closed loops 36, each loop stitched together, cover a protrusion 37, going inside the groove 31 perpendicular to the bottom 31-1 of this groove 3 1, the prestressing stress to which the elastic contact element 3 is subjected tends to hold the loops 36 pressed against the bottom 31-1 of the groove 31 of the comb 12. When making the elastic contact element 3 in the form of a metal tape 38 (FIG. 10) at its supporting end 38-5 a groove 42 / in which the protrusion 36 is placed, on the L-shaped active part 39 several longitudinal slits 40 are made, which ensures contact with the conductive connecting track 5 of the printed circuit board in several zones whose number is equal to the number of 40 holes formed by the grooves 41. In this case, the elastic contact element 38 is subjected to the prestressing force in such a way that its supporting end 38-5 is always pressed to the bottom 31-1 of the groove 31 of the comb 12, on the one hand prevents it from slipping the base end 38-5 of a protrusion 37, on the other hand, facilitates the installation or replacement of the elastic contact elements 38 in the contact device. When the elastic contact element 3 is made in the form of a wire element 43 (FIGS. 11 and 12), when the comb 12 is moved from the position of the open elastic contact element 43 (FIG. 11) to the closed elastic contact element 43 position (FIG. 12), lifting first its L-shaped active part 44 until it is at its tip touches the conductive connecting track 5 of the printed circuit board 2, after which the elastic contact element 43 deforms mainly at the level of the bending of the elasticity of its support portion 43-1 , which allows the efo of branch 43-5 to move progressively, which ensures the sliding of the top of the l-shaped active part 44 of the elastic contact element 43 along the conductive connecting tracks 5 of the printed circuit board 2, thereby ensuring their self-cleaning. When yfipyrHx is executed, the contact elements 3 are in the form of a wire element 47 (FIGS. 13-15) with a supporting section 47-3 fixed by its straight line part 47-7 in a 49, with a part 47-8 made in the form of conjugate between two arcs with opposite bulges, which is located between the body 10 and the block 49, the following occurs when the comb 12 moves to the block 49 made of an insulating material, or the bending elasticity of the part 47 of the elastic contact element 47 acts. means due to which the block 49 per extends in the direction along the movement of the comb 12 in the direction of the stop 50, the block 49 is located on the path of movement of the comb 12 in such a way that the comb 12 carries the block 49 behind itself when moving to the locked position of the elastic contact element 47. With the open position, the elastic contact element 47, the top of its L-shaped active part 48 is led away from the printed circuit board 2, if the comb 12 is moved from left to right, the pad 49 remains first in place, held elastically by the stop 50, and the L-shaped active part 48 of the elastic contact The element 47, formed by the branches 47-4 and 47-5, begins to deform in such a way that at first the L-shaped asset on the part 48 elastically touches the conductive connecting track 5 of the printed circuit board 2 and starts cleaning, then when the comb 12 touches the block 49 and then, in its movement with block 49, deforms a portion 47-8 of an elastic contact element 47, while branches 47-5 and 47-4 of an e-shaped active part 48 do not subject to deformation and the top of an L-shaped active part 48 of an elastic contact element 47 remains attached Atoms with the same elastic force, the deformation of part 47-8 with further movement of the pad 49 does not allow the top of the L-shaped active part 48 to move by the same distance, thus ensuring automatic cleaning. When performing the elastic contact element 3 in the form wire element 43, the top of the L-shaped active part 44 of which is made in the form of a closed loop 45 (FIG. 16 and 17), the following occurs during operation: at the bottom 31-1 of the groove 31 of Grevenka 12, a projection 46 is made, the perpendicular bottom 31-1 of the groove 31 with a beveled surface facing the closed loop 45 of the elastic contact element 43, during moving the comb 12 to the closing position of the elastic contact elements 43, each projection 46 automatically carries the closed loop 45 of each contact element 43, while its l-shaped active part 44 contacts the conductive connecting path 5 of the printed circuit board 2, moves along its closed The loop 45c increases the pressure on the printed circuit board 2, while the loop 45, formed by the coil, makes double contact with the conductive connecting track 5 of the printed circuit 2, the slope of the beveled surface 46 increases the pressure of the loop of the closed loop 45 to the conducting connecting path 5 of the printed circuit board 2. When the elastic contact element 3 is made in the form of a wire element 51 (FIGS. 18 and 19), the branch 51-4 of its L-shaped active part 52 is curved in the form of an arc, which provides an increase in its length, compared to with other embodiments, which provides an increase in the flexibility of the branch 51-4, than the straight-line branch 51-5, is contiguous with the branch. 51-4 and ending with the support end 51-6. At the same time, when the comb 12 moves from the open position the elastic contact elements 51 in the position in which the elastic contact elements 51 are closed, the l-shaped active part 52 first comes into contact with the conductive connecting track of the printed circuit board 2, then slides along it with an increase in the bend of its bent branch 51-4, what provides PICs Goes pressing force and purification conductive paths 5 connecting the circuit board 2. Thus it is possible to manufacture cylindrical and rectangular coupling members proposed in contact devices for connection. The use of the invention provides reliable contact and automatic. cleaning up the above elements.
