Justia Patents Panel Circuit Adapted To Move Along Panel Plane Relative To Coupling Part For Insertion Of Male ContactUS Patent for Plug connector having bent contact posts for insertion into printed circuit board holes Patent (Patent # 4,955,819)
Mar 13, 1989 - Harting Elektronik GmbH
A plug connector of the type mentioned at the beginning is disclosed in DE-OS 33 18 135. For the insertion of this plug connector there is provided an insertion tool, equipped with slots or pockets, which receive the bent contact posts and with the aid of which the operation of insertion is carried out. In this connection, however, two directions of motion, differing by 90.degree., are required for accommodation of the posts and for the actual operation of insertion, during insertion as well as in subsequent removal of the tool.
When the supplemental part 10 is introduced, it is first slipped between the contact posts 4 from below until the crosspieces 13 contact the lower surfaces 14 of the posts 4 projecting perpendicularly from the insulating member 1 and the upper side of the upper post row terminates flush with the upper side 15 of the supplemental part 10. The supplemental part 10 is then slipped in a direction displaced by 90.degree. until its front side 16 rests on the back 5 of the insulating member 1, whereupon the back of the rear/outer post row terminates flush with the back side of the supplemental part 10. This position of the supplemental part and/ or the crosspieces with reference to the contact posts is shown in FIG. 3. As the drawings show, the crosspieces 13 are arranged form-lockingly between the horizontal regions of the contact posts 4 so that a force exerted on the upper side 15 of the supplemental part or the upper side of the upper post row is transmitted forcelockingly to all contact posts and, specifically, in a direct parallel to the axes of the vertical post regions.
A plug connector provided with a supplemental part of this kind may be set up on a printed circuit board 3, the pin-shaped ends 6 of the posts extending into the circuit board holes 8, and the insertion sections 7 may be pressed into the holes with the aid of a simple insertion tool 17 (FIG. 4). In this connection, the insertion tool 17 is designed as a flat stamper 18 acting on the surface 15 of the supplemental part 10, but is preferably provided with a supporting plate 19 bent at a 90.degree. angle. This supporting plate 19 prevents the outer post rows from deflecting or buckling outwardly in the operation of insertion.
When the supporting part 20 is used, locking of the supplemental part 10 and insulating member 1 may be omitted, since after introduction of the supporting part 20, the entire arrangement is held together form-lockingly .
