Abstract:
Electrical connector for mounting on the surface of a printed circuit board, comprising a housing made of electrically insulating material provided with a number of channels for the accommodation of contact elements, and with contact elements made of electrically conducting material accommodated in the channels. The contact elements are provided with a contact end for contacting a further contact element, a connection end projecting beyond the bottom surface of the housing, for connecting the contact element to a corresponding connection face on the surface of the printed circuit board, and a base part extending between the contact end and the connection end. The connection end of the contact element is provided with a connection face facing away from the bottom surface of the housing, which connection face is displaceable relative to said bottom surface from a predetermined mounting starting position in the direction of said surface over a distance which corresponds to the difference between the greatest and smallest distances between the bottom surface of the connector and the printed circuit board with maximum permissible curvature.
Abstract:
Hold-down element (1) for holding, in a clamping manner, an electrical and/or electronic component, such as a connector, onto a substrate. The hold-down element (1) comprising a first part (2) for engaging the substrate and a second part (5) for engaging the component to be mounted. The first part (2) having an essentially flat, elongate shape provided with a member (7) which is raised with respect to the plane of the first part (2). The first part (2) being constructed so as to be weakened in an area (11) which is offset with respect to the raised member (7), so that the first part (2), under the influence of a force exerted thereon during the insertion of the hold-down element (1) in a mounting opening, can diverge in the opposite direction to the raised member (7) and can engage, in a clamping manner, the substrate by means of the divergent portion in the mounting opening. The hold-down element (1) may also be used as the connecting end of a component.

Abstract:
An electrical connector, comprising a housing of electrically insulating material. The connector is provided with a number of contact elements of electrically conducting material, each with a contact end for contacting a further connector and an L-shaped connection pin for mounting on a printed circuit board. The connection pins consist of a fixed leg which at one end is immovably connected to the contact element and a free leg running at right angles to the fixed leg. The connector is also provided with a positioning element of electrically insulating material for holding the connection pins in the correct position. One side of the positioning element adjoins the connection pin output side. The fixed legs of the connection pins run through the bores of the positioning element, which is provided with a bending anvil for bending the connection pins to an L-shape.
Abstract:
Coaxial connector provided with a body (20) of electroconductive material which extends in the casing (1) of the connector between the connection ends (18, 19) and is electrically separated therefrom. The body (20) functions as a capacitive coupling medium between the connection ends (18, 19) and thus influences the electrical connection impedance of the connector. Because a body of magnetic material (21) is accommodated at the same time, an inductive coupling can be provided and frequency-dependent impedance matching is possible.

An electrical connector provided with at least one contact element designed as a plug contact and made up of two elongated plate parts (2, 3) which extend from a base part (1), are thereto joined in a fixed manner by means of one end (4, 5) and are situated opposite one another having a mutual interspace (8). The two plate parts (2, 3) are formed so as to taper towards one another at their free ends (6, 7). The plate parts (2, 3) may be flat and form the boundary of an interspace (8) having an essentially hollow, rectangular cross section or they may have a surface which is curved transversely to their longitudinal direction.
