Description

The invention relates to an electromagnetic shield for an electrical, electronic or electro-optical connector for use in the low, medium or high voltage and / or current range, in particular for motor vehicles. The electromagnetic shielding of the connector in this case comprises a shield contact device for electrically contacting an electromagnetic shield of a mating connector. Furthermore, the invention relates to an electrical, electronic or electro-optical connector for low, medium or high voltage and / or current applications, in particular for the motor vehicle sector, wherein the connector comprises an electromagnetic shielding according to the invention.

In the electrical field (electrical power engineering, electrics, electrical engineering, electronics, etc.), a large number of electrical connection devices, socket and / or pin connectors, etc. - hereinafter referred to as (electrical) connectors or mating connectors - are known, which serve to transmit electrical currents, voltages, signals and / or data with the widest possible range of currents, voltages, frequencies and / or data rates. In the low, medium or high voltage and / or current range, and especially in the automotive sector, such connectors in hot, possibly hot, contaminated, humid and / or chemically aggressive environments have short term and / or permanent proper transmission of electrical power , Signals and / or data. Due to a wide range of applications, a large number of specially designed connectors are known.

Such connector or its housing may be connected to an electrical line, a cable, a wiring harness or an electrical device, such. B. be installed on / in a housing or on / on a printed circuit board of an electrical or electronic device; in the latter case is usually spoken by a (counter) connection device. If a connector is located on a line or a cable, it is usually referred to as a flying (plug) connector or a plug or a coupling; if it is located on / in an electrical / electronic device, this is usually referred to as a Built-in plug or a (built-in) socket. Furthermore, a mating connector is often referred to as a connector receptacle. In the field of high-voltage and high-current engineering, cable fittings are usually mentioned in the area of the relevant connectors.

Thus, in the automotive field, particularly for electric and hybrid vehicle applications, finger-safe connectors and connector heads (connectors) are needed for low to medium power. For example, such 2- / 3-pole connectors (see the prior art in 1 ) with a nominal voltage of approx. 1,000 V, a current carrying capacity of up to 40 A at -40 ° C to 140 ° C. An electromagnetic shielding of 360 ° is obligatory. Furthermore, transmission of data is playing an increasingly important role, with high data transmission requirements being a crucial part of almost every industry, such as: As the computer industry or even in the automotive industry. - High demands also exist in cable accessories, such. As cable accessories or cable connectors, for electrical voltages above 1 kV.

Many of these applications experience vibrations that persist in an operation of the particular connector over a relatively long period of time. By a comparatively strong mass acceleration of an electrical contact pairing of two contact partners of an electrical connection with vibrations, in particular two electromagnetic shields, there is a positive relative movement of the contact partners, which can lead to premature failure of the electrical contact pairing. - It is u. a. tries to address this problem by means of a refinement of the involved contact surfaces by the shields are to be made relatively insensitive to a thereby occurring fretting corrosion by means of a coating.

However, even by reducing the tolerances of the housing or the shields and additionally by a consuming refined contact surface, a harmful relative movement of the two shields is hardly avoidable or would cause significant costs at the necessary low tolerances, which would not be competitive. - These problems occur in particular with shield spring tabs with contact lugs, which initially adhere to vibrations at a zero crossing on a finished contact surface, and in a temporal connection thereto, when a static friction force is exceeded, the respective surfaces slide off each other, which leads to fretting corrosion. As a result, there is a breakdown in the refinement of the relevant contact surface (s) in time before an obsolescence of the component.

The EP 0 417 596 A1 teaches a snap fastener for a coaxial connector with two plug-in connectors, wherein an outer conductor sleeve of a first connector is provided in a front portion outside with a circumferential flat groove. The outer conductor sleeve has a slid with the flat groove, in tapered radial bore on their diameter. In the radial through hole, a ball is seated added, which is pressed by a split in the flat groove band spring radially inwardly permanently into the radial through hole.

The DE 1 217 475 A discloses an electrical connector, wherein a socket part has a cylinder inner surface and a plug part has a cylinder outer surface which is insertable with a sliding fit in the cylinder inner surface. One of the two cylindrical surfaces has a circumferential groove, wherein that part with the other cylindrical surface has at least two spring-biased, engageable for connecting the two parts in the groove locking balls. The detent balls are offset in an axial direction arranged such that while a detent ball fully engages in the groove, the other detent ball bears against a side surface or side edge of the groove.

The EP 2 246 941 B1 teaches a USB device with a USB socket and a USB plug. The USB socket has a contact chamber in which the USB plug can be received, for which the USB plug has a metal housing. Furthermore, the USB socket comprises a spring-loaded mechanism, which can engage in a mated state of the USB device in a provided in the metal housing of the USB connector through-hole. The spring biased mechanism is configured as a spring biased ball or spring loaded pin.

The JP 06163109 A discloses a locking mechanism for an electrical connector comprising a pin header and a female connector. A housing of the female connector has a mechanically biased mechanism with a coil spring and two balls. The mechanically biased mechanism is arranged in the female connector housing such that the two balls protrude on opposite sides of the female connector housing. In a mated state of the pin header with the female connector, the two balls engage in recesses in a housing of the pin header.

It is an object of the invention to provide an improved electromagnetic shield for an electrical, electronic or electro-optical connector for a low, medium or high voltage and / or current application, in particular for motor vehicles. It is a further object of the invention to provide an improved electrical, electronic or electro-optical connector accordingly. In this case, should be reduced according to the invention, a fretting corrosion in an electrical contact region of a shield of the connector with a shield of a mating connector, wherein at an occurrence of friction, a proportion of static and / or sliding friction should be relatively low. Here, both on the side of the shield of the connector and on the side of the shield of the mating connector fretting corrosion, possibly even for refined contact surfaces, be reduced.

The object of the invention is achieved by means of an electromagnetic shield for an electrical, electronic or electro-optical connector for use in the low, medium or high voltage and / or current range, in particular for motor vehicles, according to claim 1; and an electrical, electronic or electro-optical connector for low, medium or high voltage and / or current applications, in particular for the motor vehicle sector, according to claim 10. Advantageous developments, additional features and / or advantages of the invention will become apparent from the dependent claims and the description below.

The connector according to the invention accordingly has an electromagnetic shielding according to the invention.

In embodiments of the invention, the shield connector body is designed as a rolling and / or sliding body or as a round body with at least one flat, preferably spherical, rounding. So can the shield connector body For example, be designed as a partial ellipsoid, as an ellipsoid, as a partial spherical body or as a spherical body or a ball. A preferred form of the shield connector body is that of the ball body, ie, for such a case, the shield connector body is formed as a contact ball. According to the invention, in vibrations, a major frictional portion in the connecting position of the connector with the mating connector between the two shields over the shield connector body, under the condition that it can roll, is due to a rolling friction whose friction coefficient is significantly lower than that of an adhesive and also a friction coefficient Sliding friction coefficient is.

The shield contact device may be configured such that the shield connector body is at least partially providable and / or provided for / in the connection position between the shield of the connector and the shield of the mating connector. As a result, an electrical series connection of the shield of the connector, the shield connector body and the shield of the mating connector can be set up or set up. Preferably, the shield connector body is mounted on / in the shield of the connector, wherein the shield connector body is preferred for / in the / the connection position against the shield of the mating connector pressed and / or pressed. Here, the shield contact device is preferably set up such that the shield connector body is held captive on / in the shield contact device or the shield of the connector.

In embodiments of the invention, the shield contact means comprises a bearing and an abutment for the shield connector body which securely hold the shield connector body in a disconnecting position of the connector from the mating connector on the shield of the connector. Here, on the one hand, the bearing for the shield connector body preferably comparatively bending spring and / or material elastic, and on the other hand, the abutment for the shield connector body preferably comparatively rigid and / or formed materialinelastisch. Furthermore, the bearing and / or the abutment are preferably formed out of the shield of the connector, in particular cut free, or the shield contact device is teilgeststituiert by these two bearings. Furthermore, the bearing and the abutment are preferably designed such that the shield connector body is held captive even in the connection position on / in the shield of the connector.

The two bearings are preferably designed such that they forcibly guide the shield connector body such that - apart from rotational degrees of freedom - it only has mainly a single or essentially two translatory degrees of freedom. A respective translatory movement possibility is limited by a dimension or a limitation of the bearing and / or the counter bearing. The rotatory degrees of freedom of the shield connector body depend - with a steady guidance by bearings and abutment - mainly from a shape of the shield connector body. If this is spherical, the shield connector body has three rotational degrees of freedom around its main axis of rotation. The two bearings are also preferably tuned to pinch the shield connector body between them in the separation position so that it can not make unnecessary movements within its guide between the bearings.

It is possible according to the invention to omit the counter bearing and to provide only the bearing or a spring (see below). In such a case, it may be necessary to provide the shield connector body only when connecting the connector to the mating connector or only when connecting the shield of the connector with the shield of the mating connector on / in the shield contact device. Furthermore, it is possible to use two bearings (see also below) and to omit the counter bearing, or to use two counter bearings (see also below) and to omit the bearing. In the application of two abutment according to the invention, it is preferable that a shield of the mating connector opposite abutment comparatively bending spring or comparatively material elastic design.

In embodiments of the invention, the shield contact device as a bearing on a spring or an elastic region or an elastic member, by means of which or which of the shield connector body is pressed against the shield of the mating connector. Furthermore, the shield contact device can have as an abutment a guide slot for the shield connector body, at the boundary of the shield connector body in the separation position halterbar and / or supported, and / or can be guided in / for the / the connection position and / or guided. Here, the shield connector body is pressed or pressed by the bearing against the boundary of the guide slot for the shield connector body. The guide slot or its boundary lies in the connecting position of the connector with the mating connector between the shield of the mating connector and the bearing for the shield connector body or the spring or the elastic region or the elastic member of the shield contact device.

The bearing or the spring of the shield contact device or the shield of the connector is preferably as a leaf spring, a spring arm, a spring cage, a plate spring, a coil spring, a Biegefeder, a torsion spring, an elastomeric spring or a rubber spring formed. The elastic region may be a portion of the shield contactor or the shield of the connector itself. The elastic member may consist of an elastic member such. Example, be made of an elastomer, in particular of a rubber or a silicone. - The abutment or the guide slot for the shield connector body is preferably provided as a passage slot, possibly as a recess with passage slot in the shield of the connector. The guide slot may have any shape or any course, with a straight line extension is preferred. Analogous to the course of the guide slot or the thrust bearing a course of the spring or the bearing is provided.

In embodiments of the invention, the spring is preferably designed as a substantially i, l or u-shaped leaf spring or as a substantially at least u-shaped spring cage. Here, the leaf spring or the spring cage and the preferably rectangular guide slot can cooperate such that the shield connector body is halterbar and / or supported both in the separation and in the connection position on / in the screen contact device. In the separating position, the shield connector body is preferably movable only in a longitudinal direction of the shield of the connector or of the guide slot; ideally, the shield connector body is clamped by means of the bearing against the abutment. In the connection position, the shield connector body is preferably additionally movable in a transverse direction of the shield of the connector or of the guide slot. A freedom of movement in the longitudinal direction can be significantly greater than a freedom of movement in the transverse direction.

In the separation and the connection position, a movement clearance of the umbrella connector body in the longitudinal direction depends on a configuration of the guide slot or the leaf spring or the spring cage. In the connection position, the movement clearance of the shield connector body in the transverse direction depends on a dimension of the guide slot in the transverse direction and a diameter or dimension of the shield connector body. Further, of course, a spring basket may be formed such that it prevents the freedom of movement of the shield connector body in the transverse direction, which can be done by means of one or two lateral Korbwandungen. - Together form the bearing or the leaf spring or the spring cage, and the anvil or the guide slot a guide or a guide track (freedom of movement) of the shield connector body in the shield contact device. This guide may be rectilinear and / or curved, with its diameter may possibly vary slightly, in the range of not quite a diameter of the shield connector body.

In embodiments of the invention, in the separation position, the shield connector body projects with a portion out of the guide slot. When connecting the connector to the mating connector, this portion of the shield connector body is mechanically / electrically contacted / contacted by the shield of the mating connector, particularly an inner contact surface of this shield. Here, the shield connector body is pushed inwardly into the connector of the connector, the bearing or spring pressing the shield connector body against the contact surface of the shield of the mating connector. The abutment for the shield connector body remains preferably intact, but in the transverse direction of the guide slot, an additional space for movement for the shield connector body is formed; in the longitudinal direction of the guide slot remains the freedom of movement of the shield connector body.

It is of course possible to reverse the kinematics; d. H. To arrange bearing and thrust bearing of the shield contact device of the connector such, for. B. to swap that the said portion of the shield connector body when connecting the connector to the mating connector, outside of the shield of the mating connector is mechanically and electrically contacted and / or contacted. Accordingly, the shields of the connector and the mating connector must be formed; d. H. the shield of the connector is partially plugged into the shield of the mating connector. - The shield of the connector and / or the shield of the mating connector may be formed as a shield plate. In addition, the shield of the connector and / or the mating connector may have a spring tab, possibly with a contact lug, for centering the shields.

In embodiments of the invention, the shielding of the connector and / or mating connector is in one piece - d. H. their individual items are easily separable by hand or by means of a tool and without damaging their respective items -, in one piece - d. H. their respective items are not easily separable by hand or by means of a tool and possibly not without damaging their respective items -, materially one piece - d. H. their respective parts (if there are components) are cohesively fixed to each other - or integral - d. H. There is only a single, virtually only divisible by its destruction component - trained. The bearing and / or the abutment of the shield connector body is preferably formed materially integral or integral with the shield of the connector.

According to the invention Rollkontaktierung - an electrical contact transfer by means of preferably a spherical body - two shields results in a significant improvement of fretting corrosion between the shields under vibration movements, since an occurring friction coefficient is effectively reduced. A penetration of a contact surface, in particular a finished contact surface can be permanently avoided. This concerns both the shielding of a connector and the shielding of a mating connector. In embodiments of the invention can be dispensed with tight tolerances and / or a refinement of the involved contact surfaces. Furthermore, according to the invention, contact warts are obsolete, as a result of which no tearing of a surface in the region of the contact lug can occur.

The invention will be explained in more detail below with reference to embodiments with reference to the accompanying drawings. In the figures (Fig.) Of the drawing show:

The invention will be described below with reference to an application (see a prior art in 1 ) and by means of an embodiment (see 2 to 9 ) explained in more detail. Of course, the principle according to the invention - an improved electrical screen contact based on rolling and / or sliding friction by means of an additional body with respect to fretting corrosion - is of course not restricted to this type of application. Rather, the invention of basal nature, so that it can be applied to all electrical contacts of electromagnetic shielding of electrical connectors (see above and see reference numerals list). - Below are the names of a connector 1 and a mating connector 2 as well as from a warehouse 110 and a counter bearing 120 , also individually, interchangeable.

The 1 shows a high voltage electrical connector 1 according to the prior art for low to medium power for automotive applications with a conventional electromagnetic shielding 40 , The shielding 40 has a conventional shield contact tab 140 with a shield contact wart 141 on. In a connection position of the high-voltage connector 1 with one to the connector 1 complementary counterpart connector (see. 8th ) sits the shield contact wart 141 adhered to an electromagnetic shield of the mating connector. Upon vibration, a static frictional force of the shielding nipple becomes 141 repeatedly exceeded at the shield of the mating connector, it comes to a comparatively strong, progressive fretting corrosion and in a temporal sequence to a through-drive of a possibly refined contact surface of the Schirmkontaktwarze 141 ,

The invention eliminates this problem by stiction is largely avoided or occurring static friction during vibration comparatively quickly in sliding friction without comparatively large amounts of fretting corrosion, or preferably quickly converted into rolling friction. This is done according to the invention ( 2 to 9 ) by one on one as a Schirmverbinder- 102 or shield contact body 102 based electrical contacting of an electromagnetic shielding 10 a connector according to the invention 1 with an electromagnetic shielding 20 a counterpart connector 2 , The shield connector body 102 is provided as a separate component. The shield connector body 102 can be z. B. as a rolling and / or sliding, a round body with at least one planar, preferably spherical, rounding, a (partial) spherical body, a partial sphere (body), a Ball section, z. Example, as a hemisphere (body), a partial ellipsoid, an ellipsoid, a barrel roller, a cylindrical roller, a tapered roller or preferably as a ball or a spherical body - ie as a contact ball - be formed.

According to the invention, a shield contact device 100 for electrical contacting of the shield 10 of the connector 1 with the shield 20 of the counterpart connector 2 the shield connector body 102 so on, that this between the two shields 10 . 20 is predictable (see 6 to 8th and 9 ). Here is the shield contact device 100 formed such that the shield connector body 102 in a connection V, contact V or insertion position V of the connector 1 with mating connector 2 or the shielding 10 with the shield 20 (please refer 8th and 9 ) between the two shields 10 . 20 in a guided tour 130 or a guideway 130 can move. The shield contact device 100 is at least on one of the two shields 10 . 20 provided or partially by the relevant shielding 10 . 20 constituted (camp 110 and counter bearing 120 , see below); in the present case this is the shielding 10 of the connector 1 ,

A form of movement of the shield connector body 102 essentially depends on a shape of the shield connector body 102 from. The following is a spherical shield connector body 102 assumed that within the guideway 130 two translational (see arrows in 8th ) and with respect to its main axes of rotation three rotational (see arrows in 9 ) Has degrees of freedom. Preferably, the shield connector body rolls 102 between the two shields 10 . 20 , a gliding of the shield connector body 102 can occur naturally. - Comes other body, such as a partial body, z. As a hemisphere, for use, then a sliding of the shield connector body 102 within the guideway 130 common. In such a case, the divided body slides in the connecting position V both on the bearing 110 as well as opposite the shielding 20 (see below).

The possibilities of movement or a free space of the shield connector body 102 depends on a design of the guideway 130 from. This is preferred by the shield contact device 100 trained guideway 130 rectilinear and is preferably parallel to the shields 10 . 20 which preferably have parallel walls in a respective section. It is preferred that the guideway 130 partly between the two shields 10 . 20 is arranged (see below one from the counter bearing 120 standing out section 103 of the shield connector body 102 ). - Another form of guideway 130 , z. B. a guideway 130 with curve, is of course applicable in sections, if necessary. It is only necessary to ensure that the shield connector body 102 in all its possible positions in the connection position V both the shielding 10 as well as the shielding 20 simultaneously contacted electrically or the two shields 10 . 20 connects electrically with each other at all times.

Preferably, the guideway extends 130 of the shield connector body 102 in a longitudinal L and a transverse direction Q of the connector 1 , wherein the longitudinal direction L preferably also a joining, connecting or plugging direction of the connector 1 on / in the mating connector 2 is. In a height direction H of the connector 1 is the shield connector body 102 preferred only when connecting the connector 1 with mating connector 2 (Separation position T => connection position V, see 6 to 8th and below). The longitudinal L, transverse Q and height direction H is only in the 1 located. - The guideway 130 of the shield connector body 102 in the shield contact device 100 or on the shield 10 is present by means of a warehouse 110 and an abutment 120 the shield contact device 100 educated. According to the illustrated embodiment, the shield connector body 102 within the guideway 130 in the longitudinal direction L comparatively extensive (see 3 and 9 ) and in the transverse direction Q only rather restrictive move (see 5 ).

The guideway 130 is present by means of two bearings 110 . 120 , the camp 110 and the counter bearing 120 , formed, with the two bearings 110 . 120 the shield contact device 100 are associated. - The warehouse 110 can z. Example, as a spring, a leaf spring, an i-, l- or U-shaped spring arm, an at least U-shaped spring cage, a plate spring, a coil spring, a bending spring, a torsion spring, etc. may be formed. Furthermore, the bearing 120 as Elastikbauteil, z. B. having an elastomer such. As a rubber or silicone, etc., be formed. - The counter bearing 120 is preferred as a guide slot 120 for the shield connector body 102 , if necessary as a partial transit slot 120 , in the shielding 10 educated. According to the invention, the bearing presses 110 in a disconnection position T of the connector 1 from the mating connector 2 (please refer 2 to 4 and 6 ) the shield connector body 102 against the counter bearing 120 , and in the connecting position V, the shield connector body 102 inside against a contact surface 200 of the counterpart connector 2 (please refer (5) . 8th and 9 ).

The present is the warehouse 110 as a U-shaped leaf spring 110 or as at least u-shaped spring basket 110 formed (see in particular 9 ). The leaf spring 110 or the spring basket 110 is via a base spring arm 111 to the shield 10 , preferably materially integral or integral, connected, except for the connection to the camp 110 from the shield 10 is cut free. Here is the leaf spring 110 trimmed on three sides. Towards its free longitudinal end, the leaf spring 110 or the spring basket 110 after the base spring arm 111 a back wall 112 or basket wall 112 , a floor 113 or basket bottom 113 and a front wall 116 or basket wall 116 on. A function of the front wall 116 or basket wall 116 can from a front end 127 of the counter bearing 120 or the guide slot 120 be taken over (see below). Likewise, a function of the rear wall 112 or basket wall 112 from a rear end of the anvil 120 or the guide slot 120 be taken over.

Preferably, the base spring arm is located 111 in a plane of the shield 10 , where the rear wall 112 or basket wall 112 from the base spring arm 111 proceeding inwards into the shielding 10 extends into it. Here is a preferred right angle between the Basisfederarm 111 and the back wall 112 or basket wall 112 intended. Starting from the back wall 112 or basket wall 112 the floor extends 113 or basket bottom 113 preferably at a right angle, leaving the bottom 113 or basket bottom 113 preferably parallel to a respective side of the shield 10 is arranged. At one free end of the leaf spring 110 facing the bottom 113 or basket floor 113 The front wall extends 116 or basket wall 116 in turn preferably at a right angle towards an inside of the shield 10 from the ground 113 or basket bottom 113 path. The front wall 116 or basket wall 116 preferably ends within the guide slot 120 ,

When dimensioning the front wall 116 or basket wall 116 It is important to make sure that the shield connector body 102 not out of the guideway 130 can fall, which is already a comparatively short front wall 116 or basket wall 116 is achievable. This of course applies to the entire camp 110 and counter bearing 120 , - Preferred is the bearing 110 such from the shield 10 cut out or punched that after a Zurechtbiegen the preferred in this case as a leaf spring 110 or spring basket 110 designed warehouse 110 , the counter bearing 120 as preferred rectangular slot in the shield 10 remains (see 2 . 6 and 9 ). By bending the camp 110 is the counter bearing 120 a little longer than the camp 110 (see. 6 and 9 ), an emerging space is, however, when mating the two shields 10 . 20 through the shield 20 concealable (see 8th and 9 ), whereby a possibly deteriorating effect on a screen quality can be compensated again.

This is preferred as a guide slot 120 trained counter bearing 120 for the shield connector body 102 has a rear boundary 122 on, if necessary from the rear wall 112 or basket wall 112 can be taken or coincides with this. The same applies to a front limit 126 of the counter bearing 120 which, if necessary, from the front wall 116 or basket wall 116 can be taken or coincides with this. A front end 127 of the counter bearing 120 or the guide slot 120 can also be farther away from the front wall 116 or basket wall 116 lie (see above, see 9 ). In addition, the counter bearing points 120 lateral limits 124 . 125 on (see 4 and 5 ). - Preferably, the substantially rectangular guide slot 120 for the shield connector body 102 from the back wall 112 or basket wall 112 of the camp 110 as well as the lateral boundaries 124 . 125 and the front end 127 of the counter bearing 120 formed, wherein the guide slot 120 for the shield connector body 102 only up to the front wall 116 or basket wall 116 of the camp 110 is effective.

On the ground 113 or basket bottom 113 can the shield connector body 102 between the rear 112 , ( 122 ) and the front wall 116 or basket wall 116 in the longitudinal direction L reciprocate (see in particular 8th and 9 ), which is part of the guideway 130 forms. Furthermore, the shield connector body 102 in the connection position V of the connector 1 with the mating connector 2 in the transverse direction Q to between the lateral boundaries 124 . 125 of the guide slot 120 move (see in particular 5 and 8th ), which in turn forms part of the guideway 130 forms; this should become clearer from the following explanations. The preferred as a spherical body 102 trained shield connector bodies 102 Thus, in the connection position V in the longitudinal L and in the transverse direction Q within the guideway 130 move, this being both the shielding 10 of the connector 1 as well as the shielding 20 of the counterpart connector 2 contacted mechanically and electrically. Here are the two shields 10 . 20 over the shield connector body 102 electrically connected in series.

This happens as follows. The counter bearing 120 or the rectangular guide slot 120 is dimensioned in its transverse direction Q such that in the separating position T of connector 1 and mating connectors 2 a section 103 of the shield connector body 102 from the as Durchgangsausnehmung 120 designed guide slot 120 stands out (see in particular 4 ).
