695593 element shown in Fig. | .6, in three positions; in fig. 10 shows the co-rectangular element of the third embodiment and its present mixing element; in fig. 11, 12 and 13 the contact element shown in FIG. 10, in three positions; in fig. 14, i5 and 16 are shown on an enlarged scale of three possible embodiments of the contact piece shown in FIG. 10-13., The connector for printed circuit boards contains a body 1 of insulating material with a longitudinal pass 2 and recesses 3 on its side walls, elastic contact elements from a metal sheet, one ends 4 of which are fixed 6 to the wall 5 of the longitudinal groove, and the other ends 42, are bent and placed in the radial slots x 6 of the rods 7, made of insulating material and which are the mixing bodies of elastic contact elements that are installed in the housing 1. can be rotated and symmetrically relative to the longitudinal groove 2. The bent ends 4d. utfugih contact elements have a change tioe transverse fce lelthie. The bodies of motion in the form of the 7th horizon provide alternate expansion and closure of the elastic contact elements, each of which is related to the end 4 (active zone) of the conductive connecting paths 8 located on the shaft; T1H6Y 9 inserted into the longitudinal groove 2 of the housing 1 (when typing / the board 9 is in the connector, the contact elements are closed). Each contacting element is associated with: its pivot element 7; The axis around which the оп оп опы1ётётs approximately half-turn (or half-turn in a spiral) and deforms the yegada with the ends 4 and 4. The rod 7 is filled out of the insulating material, on its cylindrical surface, made of alternating hole, and there are 3 layings on the 8-nd frame. each contract element, the end of 4% of which is inserted into this slot, the rods 7 are connected to the control plane (the drawings are not shown in the drawings. At the level of each section in the side walls of the longitudinal groove 2 are filled with notches 3 whose width is larger Each of the notches 3 is bounded by protrusions 10 of rectangular section, between them there is a gap sufficient for the edge of the printed circuit board 9 to pass into it. The end 4j of each contact element is inserted in one way into the radial slot 6 of the rod 7. Moreover, the other end is 4- (loosely inserted into a groove 11, made in the wall of the housing 5, against which it is held by removable means. The connector works as follows. In the initial position, the displacement elements are in the open position, each contact element is inserted, bringing eGp to the wall 5 parallel-. hp plane Р-Р in the directions opposite to the arrow direction (Fig. 3). As a result, the end 4g is inserted into the slot 6 of the corresponding rod 7, and the non-movable end 4- is inserted into the groove 11 of the wall 5 of the housing. When End 4 is locked, its outgoing end 4 is deflected. The contact element is in this case in the position shown in FIG. 2. Immediately after installation & All contacting elements and connectors at their ends are connected to the connector. working position and you can enter the PCB 9 without teriy. between themselves conductive tracks 8 of the printed circuit board 9 (Fig. 2). Pivot the upper rod 7 in the direction of the arrow (Fig. 2 and 3), i.e. c) The direction in which you decrease the angle of rotation of each Contact Element around the rod 7 begins to increase the radial distance from part 4 (active zone) until it touches the current path 8, which relates to it primarily at the point Q. The position is shown in FIG. 3, in which a contact is made without any force between the coaxial element and tracks 8. Continuing to rotate the rod 7 in the same Direction, due to the different flexibility between parts 12 and 13, part 12 continues to move, causing part 44. of the active zone, slide along the conductive track 8, while part 45 Subject to more noticeable deformation. From here, the simultaneous sliding of the point Q on the TBconductive track 8, i.e. self-cleaning & contact surfaces and alignment of part 4 4 of the active eonB1 on track 10, which improves the conditions of current flow. Another feature that improves the wire for a short current is not between the core part 4 and the end 4j of the contact element. Thus, all contact elements relate to the corresponding elastic force of the conductive tracks 8 after removing dust that could interfere with the passage of current on the surface, which is very large due to the extrusion of the active part 4.. To unplug the connector / i. in order to push the contact elements 4 back in relation to the conducting tracks 8 of the printed circuit board 9, it is sufficient to rotate the rod 7 in the opposite direction, with the result that each contact element passes sequentially through the positions shown in FIG. 3 and 2 If it is necessary to check or replace a contact element, it is enough to disconnect its end 4, unwind its deformed part 4g (Fig. 1) and pull out the contact element in the direction of the arrow (Fig. 5). The connector shown in FIG. 1-5, differs in the constant deformation of part 4g, which increases towards the non-pointed end 4 and part 4 of the active zone, which provides, in part 13 with a longer flexibility, parallel to the Р-Р plane and slot 14. The R. shown in FIG. 6–9, differs from the previous one only in the place of constant: YESHY deformation of the 4 g part, performed in the form of a convexity 15, symmetrical with respect to the perpendicular to the P – P plane. In this case, when the connector is closed, the lateral sides of the shukle are widened, increasing the height of the point with the same effect of sliding of the point Q and typing part 4c of the active zone. Another difference is that the slot where the stationary end 4 of the contact element is inserted is closer to the P-P plane to facilitate the deformation of the volume 15 under the rod 7 when dismantling (Fig. 5) or turning the contact element, In an embodiment connector, prev: stacked in FIG. 10-13 {in the increased size in FIG. 15), the different flexibility between parts 12 and 13 is given by the fact that the cross section of part 12 has a larger surface than that of part 13. If they take, for example, a metal tape, the cross section of which is 0.80 x0.40 mm, then cut it on both sides in order to turn it, at the level of part 13, into a 0.4O x 0.40 mm square wire or a rectangular cross section of 0.3O x O, 30 mm. (Positions 16 in Figs. 10 and 15 denote side grooves that are cut to reduce the length of the contact element). The advantage of this option is to shorten the part of the Contact Element, which is the active zone of Part 4 and the end 4. In the connector according to the third variant (FIG. 14), part 12 with less flexibility has a transverse pro (| 1l of greater mechanical strength than pro (} ml of part 13. In this case, for example, you can make a contact element of elastic wire with a round section 0, 50 mm. For part 13, flatten the wire at a certain length to the section O, 25xO, 75 mm. The largest transverse dimension of this flat wire is oriented parallel to the plane of the P-R. In the connector shown in Fig. 16, the sign is flexibility between the parts 12 and 13 is ensured by the fact that part 12 has The solid profile is of greater mechanical strength than the profile of the hour 13, taking into account the forces with which the rod 7 rotates on the contact element. If a flat wire is used as a starting material, then it is sufficient in part 12 to arrange its larger size in the plane perpendicular to the axis of the rod 7 by turning it to ZR ° - (Fig. 16), and in part 13 parallel to the sjr Bar 7. This connector provides improved contact reliability and simplified design. Claim 1, Connector for printed plates, comprising a longitudinal groove body, elastic contact elements, some of which are fixed in a longitudinal groove and others are bent w and a longitudinal groove, and a displacement element mounted in the housing with a five-fold rotation This is so that, in order to increase the reliability of the contact and simplify the design, each displacement element is made in the form of a rod with radially shaped slits, and 76955938 the curved ends of the elastic contact elastic elements are made with variable elements installed in the radial cross section of the cross section, cutting rods.
