Contact element (19) having an outer conductor and an inner conductor (3) arranged inside the outer conductor, wherein the outer conductor has in one of its longitudinal axial end faces at least one contact point for contact with a contact point of a component to be contacted, characterized in that the contact point is resiliently mounted ,
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 cable-shaped (coaxial) conductors to the corresponding contact points of a printed circuit board. Likewise, such contact elements may be provided for the electrically conductive connection of two printed circuit boards.
If such contact elements serve as part of a transmission path for high-frequency signals, special demands are placed on the contact of the outer and inner conductors with the contact points of the printed circuit board.
The inner conductor is then regularly called spring contact pin, also called "Pogopin" formed. Such a spring contact pin comprises a sleeve and a bolt partially guided within the sleeve with a contact head. A coiled between the bolt and the sleeve coil spring causes a spring load of the bolt in its extended position. The spring load causes the contact head of the bolt always has a secure contact with sufficient contact pressure with the contact point even when tolerated due to different distances of the spring contact pin to the contact point on the circuit board. The contact head is regularly hemispherical in shape, which compensates for tolerance-related deviations from the vertical orientation of the spring contact pin to the contact point, d. H. 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.
Based on this prior art, the present invention seeks to provide an improved generic contact element. In particular, 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.
This object is achieved by a contact element according to independent claim 1. Advantageous embodiments are the subject of the dependent claims and will become apparent from the following description of the invention.
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.
It can preferably be provided that the end face of the outer conductor is formed by a contact ring, which is connected to a housing of the outer conductor. 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 (eg as a press fit), by a positive fit (eg by means of a bayonet or threaded connection) and / or by a material fit (eg by soldering or welding). ,
In one embodiment it can be provided that the contact ring is formed as a (preferably disk-shaped) corrugated ring. Such 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. Preferably, the corrugated ring is made of a metallic material such. B. copper formed. As a result, an electrically conductive contact ring can be created in a cost effective manner, which can also exploit the advantageous elastic properties of the material for the integration of the resilient mounting of the contact point.
In a further advantageous embodiment, the preferably several resilient mounted contact points of the contact ring may be formed by one or more spring tabs, which are preferably inclined in the direction of a central 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.
In one embodiment it can be provided that 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.
In a further preferred embodiment of the contact element according to the invention can be provided that 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.
Of course, there is the possibility that a contact ring of the contact element according to the invention comprises several or all of the spring contact contact points described as preferred. For example, a trained as a corrugated ring contact ring may be additionally formed with spring tabs. Also, 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 invention will be explained in more detail with reference to embodiments shown in the drawings. In the drawings shows:

The 1 to 3 show an embodiment of a contact element according to the invention 19 , This serves to a (coaxial) cable 1 with an associated contact point of a printed circuit board 2 (see. 7 to 11 ) connect to. It should be between the cable 1 and the circuit board 2 Radio frequency signals are transmitted.
The contact element 19 has an inner conductor 3 of electrically conductive material, in particular a metal (for example copper and / or steel), which is designed in the form of a spring contact pin. This includes a sleeve 4 with a blind hole extending in the longitudinal axial direction. There is a bolt in this blind hole 5 movably mounted, with a contact head of the bolt 5 the blind hole of the sleeve 4 surmounted. The bolt 5 is by means of a (screw) spring 6 resilient in the sleeve 4 stored, with a bias of the spring 6 the bolt 5 acted upon in the direction of the open end of the blind hole. The contact head of the bolt 5 has a curved and in particular hemispherical contact surface which is in contact with the associated contact point of the printed circuit board 2 is provided.
The inner conductor 3 is in inner holes of two insulating bodies 7 made of electrically insulating material, in particular plastic. The sleeve is supported 4 with an arranged in the vicinity of its cable-side end annular shoulder 8th on the cable side arranged insulation body 7 while an annular projection 9 on the bolt 5 in the vicinity of the contact head whose spring-loaded moving out of the sleeve 4 by a striking on the cable side arranged insulation body 7 limited.
A connection of the inner conductor 3 of the contact element 19 with an inner conductor of the associated cable 1 via a plug connection. This is the back end of the sleeve 4 in the form of a longitudinally or multiple slotted socket 10 formed, in which a plug of the inner conductor of the cable 1 is inserted.
The the inner conductor 3 receiving insulation body 7 are held in inner holes of an outer conductor. This results in a coaxial position of inner conductor 3 and outer conductor (with respect to their longitudinal axes). The multi-part outer conductor comprises a first, substantially cylindrically shaped housing part 11 , with a second, also substantially cylindrically shaped housing part 12 is screwed. For this purpose, the first housing part forms 11 an external thread that with an internal thread of the second housing part 12 is screwed.
In the cable-side end of the second housing part 12 is a soldering jack 13 (made of an electrically conductive material) inserted and fixed non-positively. The soldering jack 13 and the second housing part 12 can consist of different materials. One in the receiving opening of the soldering jack 13 plugged and thus electrically conductively connected outer conductor of the cable 1 is used to fix the cable 1 with the solder jack 13 soldered.
The second housing part 12 is on the outside of a spring 14 surrounded, the exact positioning of the contact element 19 in the in the 7 to 11 used and described in more detail later connecting device is used.
The front longitudinal axial end surface of the outer conductor which is in contact with the contact point of the printed circuit board 2 is provided by a contact ring 28 formed in the form of a corrugated ring having along its circumference a wave-shaped course. In this case, a total of three wave crests and wave troughs are formed, wherein the wave troughs on the end face of the first housing part 11 the outer conductor rests, while the wave crests as contact points for contacting the contact point of the printed circuit board 2 are provided. In the area of the wave troughs, the contact ring points 28 In addition, each one radially outwardly facing tab 15 on. The tabs 15 are in a space between the first housing part 11 and a non-positively connected thereto lid 16 is formed, positively fixed. Preferably, the tabs 15 not significantly between the first housing part 11 and the lid 16 braced, leaving a rotatable attachment of the corrugated ring 14 on the housing of the outer conductor results. At a contact of the corrugated ring 14 with the contact point of the circuit board 2 the corrugated ring is deformed more or less, which due to the elastic properties of the formed example of copper corrugated ring 14 leads to a spring load formed in the form of wave crests contact points. The deformation of the contact points can be done individually, thereby balancing 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 , he follows. Despite this misalignment is due to the spring load a permanent contact of all contact points of the corrugated ring 14 with the associated contact point of the circuit board 2 secured.
The 4 to 6 show alternative embodiments for contact rings 28 in place of the corrugated ring 14 at the contact element 19 according to the 1 to 3 can be used.
At the contact rings 28 according to the 4 and 5 become the contact points of spring tabs 17 formed, the one-piece with a flat, annular body 18 of the contact ring 28 are formed. Here are the contact tabs 17 , which in the embodiment according to the 4 pointing radially inward and in the embodiment according to the 5 arcuately about a central axis of the contact ring 28 are arranged slightly inclined inclined in the direction of the central axis arranged. As a result, those of the spring tabs 17 trained contact points (in the direction of the longitudinal axis of the contact element 19 ) a defined distance to the body 18 on. These can thus be in contact with the contact point of the circuit board 2 individually in the direction of the cable-side end of the contact element 19 Dodge spring loaded. This allows a compensation of a non-uniform distance of the contact point of the circuit board 2 from the main body 18 of the contact ring 28 , in particular highlighted by a not exactly parallel alignment to each other. Despite this misalignment is due to the spring load a permanent contact of all contact points of the contact element 19 with the associated contact point of the circuit board 2 secured.
In the embodiment according to the 6 is the contact ring 28 formed of metal felt, that is, this consists of a plurality of metallic fibers (wires), which are intertwined intertwined. Several of the fibers form one or more contact points, which due to an elastic deformation of the individual fibers and a relative movement of the fibers with one another in contact with the contact point of the circuit board 2 can dodge elastically. Also, this embodiment of a contact ring 28 allows a permanent contact and thus a secure transmission of high frequency signals between the cable 1 and the circuit board 2 ,
The 7 to 11 show a connecting device, by means of several contact elements 19 , as in the example 1 to 3 are shown, to the circuit board 2 can be connected.
The connecting device comprises a housing with a lower housing part 20 and an upper housing part 21 , The lower housing part 20 indicates one of the number of contact elements 19 corresponding number of through holes, in each of which a contact element 19 is plugged in. In the area of that outer surface of the lower housing part 20 leading to the circuit board 2 is directly adjacent (contact side), is provided within the passage openings in each case an annular, the diameter of the passage openings decreasing paragraph. At these paragraphs, the recorded in the through holes contact elements 19 contact side. In this case, the diameter of the passage openings formed by the shoulders is so large that the end face on the outer conductor of the contact elements 19 protrude trained contact points and thereby protrude beyond the lower housing part.
The upper housing part 21 surrounds the cable-side ends of the contact elements 19 , Within the upper housing part 21 is a backstop 22 arranged, which has substantially the same outer dimensions as the lower housing part 20 and also also has a plurality of through holes, in each of the cable-side end of the outer conductor of one of the contact elements 19 is plugged in.
In this case, the diameter of the through openings is only slightly larger than the outer diameter of the cable-side ends of the contact elements 19 , whereby the cable-side ends of the on the second housing parts 12 the outer conductor of the contact elements 19 put on feathers 14 on the counterholder 22 support. In conjunction with the front support of the springs 19 on an annular shoulder of the second housing part 12 the outer conductor of the contact parts 19 can be achieved in the mounted state of the connecting device, a spring bias, through which the contact elements 19 against the paragraphs in the through holes of the lower housing part 21 be pressed. This should in particular a good contact of the contact points of the outer conductor of the contact parts 19 with the associated contact points of the circuit board 2 be guaranteed.
A connection between the lower housing part 20 , the counterpart 22 as well as the upper housing part 21 can be done in any way. Preferred is a releasable connection, which may be formed for example by a latching connection.
On the long sides of the lower housing part 20 are each two locking tabs 23 made of an elastic, preferably metallic material (eg steel). The locking tabs 23 project beyond the contact side of the lower housing part 20 and thereby protrude into through holes 24 the circuit board 2 , Each of the locking tabs 24 forms at least one projection, behind the edge of the corresponding passage opening 24 the circuit board 2 engages, creating a latching connection between the connecting device and the circuit board 2 will be produced.
As in particular from the 11 it can be seen, the through holes 24 the circuit board 2 graduated. Each of the steps (shown are two, more than two can be advantageously provided) forms an edge, behind which the projection of the associated locking tab 23 the connecting device can engage. Distinguished by their distance from the contact-side surface of the circuit board 2 distinctive stages of the passage openings 24 allow a simple and secure connection of the connecting device to the circuit board 2 even with comparatively large, tolerance-related dimensional deviations, in particular of the components of the connecting device.
The lower housing part 20 the connecting device has two additional through holes, in addition to the through holes for the contact elements 19 arranged and - like this - on the contact side of the lower housing part 20 have an annular shoulder for diameter reduction. These two through holes each take a threaded sleeve 25 on, which is preferably formed of metal. In these threaded sleeves 25 (with internal thread) can each be the external thread of a fastening screw 26 be screwed. The fixing screws 26 then protrude through additional passage openings 27 the circuit board 2 and supported on the contact side opposite side of the PCB 2 from. As a result, the connecting device can optionally, in particular for special requirements for a permanently secure attachment, with the circuit board 2 be screwed. The screw heads of the mounting screws are provided with a relatively large diameter and - optionally - with a ribbing on the edge, which makes a manual tightening and loosening of the screw possible.
The dimensioning of the elements of the connecting device and the circuit board 2 and the interpretation of the spring stiffness of the springs 6 . 14 and the spring-acting contact rings 28 the contact elements 19 are preferably chosen so that the contact side of the lower housing part 20 the connection device not directly on the adjacent surface of the circuit board 2 bears; rather, a small gap should remain. Otherwise, could be a concern of the lower housing part 20 on the circuit board 2 a defined spring-loaded contact of the inner and / or outer conductor (or of the contact rings 28 trained contact points) of individual or all of the contact elements 19 hinder.
