Definitions
- the invention relates to a contact element with an outer conductor and an inner conductor disposed within the outer conductor, which are each provided on the front side for contacting a component and in particular a printed circuit board.
- Such contact elements can serve, for example, to connect kabeiförmige (coaxial) conductor to the corresponding contact points of a circuit board. Likewise, such contact elements may be provided for the electrically conductive connection of two printed circuit boards.
- the inner conductor is then regularly formed as a spring contact pin, also called a "pogopin.”
- a spring contact pin comprises a sleeve and a bolt partially guided within the sleeve with a contact head
- a coil spring supported between the bolt and the sleeve causes spring loading of the bolt
- the spring load causes the contact head of the bolt to differ even if the tolerance is changed
- Distances of the spring contact pin to the contact point on the circuit board always has a secure contact with sufficient contact pressure with the contact point.
- the contact head is regularly hemispherical in shape, whereby tolerance-related deviations from the vertical orientation of the spring contact pin are compensated for the contact point, ie the contact surface of the contact head is always substantially the same size.
- the outer conductor which regularly concentrically surrounds the inner conductor has an annular end face, which in many cases also serves as a contact surface. This is disadvantageous in particular in the case of a tolerance-dependent not exactly perpendicular alignment of the outer conductor to the contact surface of the printed circuit board. Then, a lateral lifting of the contact surface leads to a contact with the contact point in only a comparatively small portion of the end face of the outer conductor. Such "uncontrolled" contact is particularly undesirable when using the contact elements for the transmission of high-frequency signals.
- the present invention seeks to provide an improved generic contact element.
- a generic contact element with respect to the contact between the outer conductor and the associated contact point on the circuit board should be improved.
- the invention solves this problem by providing in a generic contact element with an outer conductor and a (preferably coaxially) disposed inside the outer conductor inner conductor, wherein the outer conductor at (at least) one of its longitudinal axial end faces (at least) a contact point for contact with a contact point a component to be contacted and in particular a printed circuit board, the contact point is resiliently mounted.
- the end face of the outer conductor is formed by a contact ring, which is connected to a housing of the outer conductor is. This simplifies the integration of the resilient mounting of the contact point and thus the production of the contact element according to the invention.
- a connection of the contact ring with the housing of the outer conductor can be achieved in a simple manner that the contact ring is at least partially held edgewise between the housing and a lid.
- the cover may be connected to the housing in any desired manner, for example by a force fit (for example as a press fit), a form fit (for example by means of a bayonet or threaded connection) and / or a material fit (for example by soldering or welding).
- the contact ring is formed as a (preferably disk-shaped) corrugated ring.
- a corrugated ring has a wave-shaped course in the circumferential direction, as a result of which at least one, preferably several corrugation-wave trough combinations are created. Then, for example, the wave crests may serve as contact points for contact with the contact point of the printed circuit board and the wave troughs as contact points, which ensure contact with the housing of the outer conductor.
- the corrugated ring is made of a metallic material such as e.g. Copper formed.
- the preferably a plurality of resiliently mounted contact points of the contact ring may be formed by one or more spring tabs, which preferably run inclined in the direction of a center axis of the contact ring.
- the spring tabs are preferably integrally connected to a main body of the contact ring, wherein preferably (at least) one contact point at the free end (preferably each) of the spring tabs is provided.
- the spring tabs are designed to extend radially inwardly. It is also possible to form the spring tab arcuately running around the central axis of the contact ring.
- the contact ring is formed (at least partially) of metal felt.
- Metal felt is a spatial structure of intertwined fibers, which consist at least partially of electrically conductive material. An elasticity of the contact ring then results from an elastic deformation of the fibers in conjunction with a relative mobility between them.
- the contact points of a metal felt contact ring may be formed by portions of the fibers.
- a contact ring of the contact element according to the invention comprises several or all of the spring contact contact points described as preferred.
- a trained as a corrugated ring contact ring may be additionally formed with spring tabs.
- a corrugated ring, optionally with additional spring tabs be combined with an underlying second contact ring made of metal felt.
- a contact ring of the contact element according to the invention can thus also have a multilayer structure.

- the tabs 15 are not significantly clamped between the first housing part 11 and the cover 16, so that there is a rotatable attachment of the corrugated ring 14 on the housing of the outer conductor.
- the corrugated ring 14 Upon contact of the corrugated ring 14 with the contact point of the printed circuit board 2, the corrugated ring is deformed more or less, resulting in a spring load of formed in the form of wave crests contact points due to the elastic properties of the example formed of copper corrugated ring 14.
- the deformation of the contact points can be done individually, whereby a compensation of a non-uniform distance of the contact point of the circuit board of the corrugated ring 14, in particular caused by a not exactly vertical orientation of the longitudinal axis of the contact element 19 to the contact point of the circuit board 2, takes place. Despite this misalignment a permanent contact of all contact points of the corrugated ring 14 is secured with the associated contact point of the circuit board 2 by the spring load.

- the passage openings 24 of the printed circuit board 2 are stepped.
- Each of the steps (shown are two, more than two can be advantageously provided) forms an edge, behind which the projection of the associated latching tab 23 of the connecting device can engage.

- the dimensioning of the elements of the connecting device and the printed circuit board 2 and the interpretation of the spring stiffness of the springs 6, 14 and the spring-acting contact rings 28 of the contact elements 19 are preferably selected so that the contact side of the lower housing part 20 of the connecting device not directly on the adjacent surface of the Printed circuit board 2 is applied; rather, a small gap should remain. Otherwise, a concern of the lower housing part 20 on the printed circuit board 2 could hinder a defined spring-loaded contact of the inner and / or outer conductor (or the contact points formed by the contact rings 28) individual or all of the contact elements 19.
