Mobile telephone equipment with multi-core electrical connection devices

The invention relates to mobile telephone devices according to the preambles of claims 1 and 4.

Known high-frequency connection devices are designed as so-called coaxial plug connections. They have a plug and a socket as connecting elements. The plug and socket each consist of an inner conductor and a sleeve-like outer conductor used for shielding. In the connection position, the inner conductors and the outer conductors of the plug and socket engage with each other in an axially contacting manner. A dielectric layer is arranged between the inner conductor and the outer conductor. This is designed as a coating of at least one of the outer conductors and inner conductor of the plug and socket. The coaxial connectors with interlocking components are therefore relatively complex and delicate, and are also susceptible to wear.

Such known coaxial connectors are often used for applications including telecommunications equipment such as mobile phone equipment, e.g. hands-free systems in motor vehicles. The coaxial connection is used to transmit the antenna signals between the mobile phone and a holder designed to temporarily hold the mobile phone, known in practice as a cradle, and to transmit these signals between the cradle and a base part fixed to the vehicle, with which the cradle can be coupled to form a holder. The connecting elements of the coaxial connectors permanently installed in these components, namely the socket and plug, are susceptible to wear and contamination. In practice, it often happens that the socket becomes clogged with dirt particles or that condensation collects in it. Furthermore, in practical use, mechanical damage sometimes occurs due to bending of the delicate components of these plug connections. This also results in handling disadvantages when inserting and removing the mobile phone in and out of the cradle and when placing and releasing the cradle on the vehicle-mounted base part, because the electrical coaxial connection must be adjusted or released at the same time as the mechanical coupling devices are connected and released. In addition, in addition to the electrical power supply and signal line, there are also further electrical connection devices between the mobile phone and the cradle and between the cradle and the base part, which also have to be handled automatically when mechanically connecting and releasing. These electrical connection devices are constructed and function differently than the coaxial connectors used, which makes the actual construction and handling when coupling and releasing this complex overall arrangement even more complicated.

The invention is based on the object of improving a mobile telephone device in such a way that the handling when releasing and connecting the mechanical and at the same time electrical coupling between the cradle and the base part that can be permanently mounted in the motor vehicle and/or between the mobile telephone and the cradle can be carried out easily and with less wear.

The invention solves this problem with the mobile telephone devices according to claims 1 and 4.

The mobile phone device provides electrical connection devices for the electrical connection of the base part, which can be installed stationary in the motor vehicle, to the holder, which is usually designed as a cradle and temporarily holds a mobile phone, and/or for the electrical connection of the mobile phone and the holder, which is designed as a cradle. The connection devices can be designed as coaxial connectors or as non-coaxial electrical connection devices, with essentially the same mechanical structure. In each case, these are contact connectors, which are in contact with their front ends in the connection position.

The two connecting elements each have a dielectric body in which several separate conductors are arranged parallel and spaced apart from one another.

The versions that are not designed as coaxial connectors can be used for power supply or for signal transmission between the components of the mobile telephone device. They can be designed in such a way that the various conductors are arranged in one or more rows, without it being important that the conductors are arranged symmetrically or coaxially.

The conductors running in the dielectric, which interact with each other at their ends in the connected position, form multi-core contact connectors.

Other versions, which are designed as coaxial connectors, have a structure with an inner conductor and an outer conductor and are used in the mobile phone device as coaxial connectors for conducting the antenna signals between the mobile phone and the cradle or between the cradle and the base part fixed to the motor vehicle.

Instead of the conventional sleeve-shaped shielding in the plug and socket, the coaxial connection device now has an outer conductor device consisting of several separate outer conductors. In order to achieve good shielding, the outer conductors are arranged parallel to one another and at a distance from and parallel to the inner conductor.

This means that this new type of coaxial conductor is constructed like a multi-wire electrical connector.

A significant advantage is that in the connection position the associated outer conductors and the inner conductors of the connecting elements are arranged axially aligned with one another and interact with their ends facing one another. The coaxial connector can thus be designed as a contact device that abuts in the connection position. Preferably, the front ends facing one another in the connection position are designed as contact ends only in their axially outermost region. It can be provided that in the connection position they touch one another in a common contact surface, which preferably extends essentially perpendicular to the axial extension of the outer conductors and inner conductors.

This means that the axial end surfaces, for example, are flat against one another. These end surfaces can be flat, but can also be complementarily curved. If these end surfaces are only formed in the end region of the interacting outer conductor and inner conductor of the connecting elements, the common contact surface generally extends perpendicular to the axial extension of the conductors in question. Furthermore, particularly advantageous designs are provided in which, in the connected position, the contact ends touch one another at a common contact point or in a common contact line. This is the case when one contact end is designed as a flat front surface and the other contact end as a spherical tip or as a point or edge. Advantageously, the designs can dispense with socket-like receptacles and complementary plugs. For centering reasons, however, in certain designs the contact ends can also be designed to engage more or less complementarily, without the typical filigree plug socket connection of the conventional coaxial plugs having to be implemented.

Significant advantages when used in mobile phone devices arise from the fact that the connectors can each be designed as contact connectors which are in contact only at the front ends facing each other, preferably in the axially outermost area of the front ends in the connection position, and thus either the contact surfaces lie flat on top of each other or the contact surfaces with contact tips or contact caps come into contact in the connection position, which results in simple handling when connecting and disconnecting at the same time as the mechanical coupling and disconnection of the mobile phone and cradle or cradle and base part and mechanical damage and wear of the connecting elements is avoided.

Particularly advantageous designs for coaxial connectors in terms of design and manufacturing technology are obtained when the outer conductors and the inner conductor are fixed in a dielectric body, preferably embedded in it, in one of the connecting elements, and the outer conductors and the inner conductor are movably supported, preferably spring-supported, in a dielectric body in the other connecting element. These spring-supported conductors can be designed as so-called spring pins, in that they are each designed as multi-part bodies. They can have a receiving sleeve fixed in the dielectric body, a spring arranged in the receiving sleeve, and a pin guided in the receiving sleeve and supported on the spring. Particularly high functionality is achieved when the pin-shaped conductors fixed in the dielectric body, which extend through the dielectric body, are arranged flush in the area of their contact end in the front face of the dielectric body formed on the contact side, and the spring-supported contact pins arranged in the other connecting element, which extend through the dielectric body of their connecting element, are arranged with their contact end projecting over the front face formed on the contact side of this connecting element as spring-loaded contact heads and, in the connecting position in contact with the associated contact pin, are pushed in towards the dielectric body against the effect of their spring. This compensates for manufacturing tolerances of the components provided with the connecting elements in the connecting position and ensures electrical contact in the connecting position.

In order to ensure centering in the connection position, different measures can be provided, e.g. a centering device, which can also be designed simultaneously or alternatively as a mechanical coupling device, can be connected to the connecting elements or to a

connected part. For example, a centering pin can be provided between the connecting elements, which engages in a complementary recess in the connected position. Such a centering pin can be designed as a separate centering pin in the area of or outside the connecting elements carrying the electrical conductors. Alternatively or additionally, one or more of the conductors, i.e. outer conductor or inner conductor, can take on the function of a centering pin. This can be done by the conductor or conductors in question engaging in one or more complementary recesses in the connected position. These recesses can be realized in the area of the contact ends, e.g. by correspondingly complementary, e.g. spherical contact surfaces. Alternatively or additionally, all contact ends of the conductors of the two connecting elements can lie in a complementary, e.g. curved common surface in order to achieve centering in the connected position.

a hands-free device with the various electrical contact connection devices.

First, reference is made to Figs. 1 to 6 and the connection device 101 shown there is described in terms of structure and function. In the embodiment shown, it can be used as a coaxial connector in a high-frequency line, e.g. an antenna line. It consists of a first connection element 101a and a second connection element 101b, which in the connection position are in contact with their contact sides facing each other (see Fig. 2).

The connecting elements 101a, 101b are mounted on circuit boards 105a and 105b, respectively, in the installed position shown in Figs. 1 and 2. The circuit boards 105a, 105b can be mounted in device parts not shown in Figs. 1 and 2, which are brought together, preferably mechanically coupled, to form the RF connection.

The two connecting elements 101a and 101b are designed as coaxial connecting elements. Each of these two coaxial connecting elements 101a, 101b has a dielectric body, which is designed as a cuboid block with a square cross-section (see Fig. 3a and 5). In the embodiment shown, nine conductors 102a, 103a; 102b, 103b are embedded in the dielectric body in each connecting element 101a, 101b. In the case shown, these nine conductors are arranged in three parallel rows with three conductors per row. The outer conductors 102a, 102b are arranged in a configuration with a square cross-section. The central conductor 103a, 103b runs through the center of this square configuration. The first connecting element 101a thus has eight such outer conductors 102a and one central conductor 103a. The second connecting element 101b has eight outer conductors 102b and one central conductor 103b in a corresponding manner. Adjacent conductors in a row each have

the same distance apart. The conductors extend axially parallel to one another and in the axial direction through the dielectric body perpendicular to its square cross-sectional area. When the two connecting elements 101a, 101b are connected, the nine conductors 102a, 103a of the first connecting element are aligned with the nine conductors 102b, 103b of the second connecting element 101b. The central conductor 103a, 103b forms the inner conductor of the coaxial connection. The outer conductors 102a, 102b form the shielding connected to ground in this coaxial connection.

In the first connecting element 101a, the conductors 102a, 103a are designed as pins fixed and embedded in the dielectric body. These are metal pins, e.g. made of gold-plated copper. They are each designed identically. Their axial ends are in the area of the front ends of the dielectric body. They have contact ends which, in the connection position of the HF connection device, face the second connecting element 101b and are in contact with the contact ends of the conductors 102b, 103b of this second connecting element 101b. These contact ends of the pins have a flat contact surface and are flush with the front surface of the dielectric body. The other ends of these conductor pins 102a, 103a are designed as connection ends which protrude beyond the end face arranged on this side of the dielectric body and are connected to a circuit board 105a, e.g. via soldering points, in the installation position shown in Fig. 1 and 2. They can be connected to a coaxial line laid on the circuit board or connected there.

The conductors 102b, 103b of the second connecting element 101b are designed as spring-loaded pins. They are each designed identically to one another. As shown in detail in Fig. 6, the spring-loaded pin consists of a

Receiving sleeve h, a helical compression spring f arranged in the receiving sleeve and a pin s which is guided axially displaceably so as to penetrate into the receiving sleeve h. This pin s has a bearing recess on its inside into which the spring f supported on the bottom of the receiving sleeve h engages with its upper end in order to support itself there. The pin s has a collar-shaped edge which abuts on the inside of the upper inwardly bent edge of the sleeve h in the position shown in Fig. 6. The receiving sleeve h is fixedly embedded in the dielectric body. The bottom of the receiving sleeve h protrudes beyond the front side of the dielectric body and forms the connection end which, in the installation position in Figs. 1 and 2, is connected to a circuit board 105b via a soldering point. The free end of the pin s which is spring-mounted in the receiving sleeve h protrudes slightly beyond the front side of the dielectric body in the non-connected position. This free end forms the contact end which, in the connection position of this HF connection device 101, is in contact with the associated contact end of the associated conductors 102a, 103a of the connection element 101a. The spring-mounted pin is pushed slightly into the dielectric body of the connection element against the effect of the spring.

In the embodiment in Fig. 7, the HF connection device 101 forms the HF connection between a mobile phone 1 and a cradle 14 designed as a holding shell for the mobile phone 1. The first connection element 101a with the fixed pins and the overall flat contact surface is fixed in the bottom of the cradle 14 facing the bottom of the mobile phone 1. The circuit board 105a, on which the connection element 101a is arranged (see Figs. 1 and 2), is fixed in the cradle 14. The second connection element 101b with the spring pins is fixed in the bottom of the mobile phone 1. The circuit board 105b (see Figs. 1 and 2) is an integral part of the mobile phone 1. The arrangement

·

The connecting elements 101a, 101b are each designed such that the front surface of the dielectric body is flush with the base of the cradle 14 holder or with the underside of the mobile phone 1. The contact ends of the conductor pins fixed in the connecting element 101a are flush with the front surface of the dielectric body, so that the entire front and contact surface of the connecting element 101a is flush with the base of the cradle 14 holder and thus there are no recesses or projections in the area of the connection of this coaxial connection. The contact ends of the spring-mounted pins of the connecting element 101b mounted in the underside of the mobile phone 1 protrude beyond the front surface of their dielectric body in the non-connected position. Since the front surface of the dielectric body is flush with the underside of the mobile phone 1, the contact ends of the nine spring-loaded contact pins form protruding spring-loaded heads, while the remaining area of this connecting element 101b is flush with the underside of the mobile phone.

In the position of the mobile phone 1 inserted into the cradle 14 (not shown in Fig. 7), the mobile phone 1 is positively engaged in the partially undercut complementary receptacle of the cradle 14. The underside of the mobile phone 1 rests on the bottom of the receptacle, particularly in the area in which the connecting elements 101a, 101b are arranged, so that when the mobile phone is inserted into the cradle, the contact heads of the conductor pins 102b, 103b rest on the contact surfaces of the conductor pins 102a, 103a. The spring-mounted contact pins (see Fig. 6) are pushed more or less far into their respective receptacle sleeve h against their bearing spring f. In the connection position, which is shown schematically in Fig. 2, the HF connection between the mobile phone 1 and the cradle 14 is established. An antenna cable (not shown) is connected to the circuit board 105a arranged inside the cradle 14 and is connected to an outboard antenna

of the motor vehicle, i.e. an external antenna located outside the vehicle interior.

As shown in Fig. 8, a base part 12 is provided which can be mounted in a fixed location, in particular in a motor vehicle, and on which the cradle 14 can be mounted via a mechanical locking connection. An HF connection device 101 is also provided between the base part 12 and the cradle 14. This is also designed identically to the HF connection 101 described in connection with Figs. 1 and 2. For this purpose, a connecting element 101a is arranged in the top of the base part 12 and a connecting element 101b in the bottom of the cradle 14. The connecting elements 101a, 101b are also installed here in such a way that the front surface is flush with the installation surfaces on the top of the base part 12 or on the bottom of the cradle 14. In this case too, the circuit boards 105a and 105b are fixed in the base part 12 or the cradle 16. In the mechanical locking position between cradle 14 and base part 12, the electrical contact of the connecting elements 101a, 101b and thus the RF connection is maintained.

The mechanical coupling of the cradle 14 and the base part 12 is carried out via a special locking device. As shown in Fig. 8, this can be designed in such a way that locking lugs 13 arranged on the base part 12, which are arranged in a cantilevered manner on the upper side of the base part 12, automatically engage in locking recesses arranged on the underside of the cradle 14 when the cradle 14 is placed on the base part 12.

On the front side of the base part 12, a coaxial connector socket 12b is designed for connecting an antenna cable to an external antenna, e.g. an outboard antenna of the vehicle. This connector socket 12b is designed as

conventional coaxial socket. It is connected to the connecting element 101a of the RF connection 101 via the circuit board 105a.

As can be seen in Fig. 8, a further electrical contact connection device 111 is formed in the base part 12 at a distance from the HF connection device 101. In contrast to the connection device 101, it is not designed as a coaxial connection device, but rather as a multi-wire electrical power supply and signal line connection device, specifically as a so-called low-frequency connection, or NF connection for short. It consists of a connection element 111a, which is arranged in the top side of the base part 12, and a connection element 111b (not shown in Fig. 8), which is arranged in the bottom side of the cradle 14. These two connecting elements 111a, 111b correspond in their structural design to the connecting element 101a or 101b in that they each have a corresponding dielectric body in which, in the case of the connecting element 111a, contact pins are fixedly embedded and, in the case of the connecting element 111b, spring-loaded contact pins are mounted in the dielectric body. In contrast to the HF connecting device 101, in the electrical connector 111 the dielectric bodies are each elongated rectangular cuboids in cross-section. The contact pins of the connecting element 111a and the spring-loaded contact pins of the connecting element 111b are each arranged in just two rows, each with eight fixed contact pins or eight spring-loaded contact pins. These pins each form the conductor wires of the electrical connection. In contrast to the RF connection 101, they are not designed as an inner conductor and an outer conductor to form a shield, but rather as separate wires of this multi-wire electrical connection. The connection device 111 therefore forms a non-coaxial electrical connection for the power supply and electrical signal line. The connection elements 111a and 111b are in

•··· · t

in a corresponding manner, as shown for the HF connection device in Figs. 7 and 8, connected to circuit boards 105a and 105b, respectively, which are fixedly arranged in the base part 12 and the cradle 14, respectively. In a modification compared to Fig. 8, the LF connection device 111 and the HF coaxial connection device 101 can be designed in a common structural unit, i.e. the connecting elements 111a and 101a and the connecting elements 111b and 101b can each be designed as a structural unit in a respectively combined connecting element a or b, preferably each with a common dielectric body a or b, e.g. designed as an elongated cuboid body.

As shown in Fig. 8, the base part 12 has a conventional connection socket 12a on its outer end face adjacent to the coaxial socket 12b. This socket 12a is electrically connected to the connecting element 111a via the circuit board 105a.

As can be seen in Fig. 7, a non-coaxial electrical contact connection device 111 is also provided between the mobile telephone 1 and the cradle 14. It can be constructed in the same way as the contact connection 111 described in connection with Fig. 8. In Fig. 7, it serves to electrically connect the mobile telephone 1 to the cradle 14. The connecting element 111b is arranged in the front foot end of the mobile telephone 1 and the connecting element 111a in the associated front area of the receptacle 14a of the cradle.

The basic structure of the mobile telephone device with hands-free device is described below with reference to Fig. 9, in which the contact connections 101, 111 described above are intended for use as a preferred application. The mobile telephone device with hands-free device shown is designed in such a way that the

The mobile phone can be exchanged for a mobile phone of a different type. The mobile phone device comprises a mobile phone holder with a base part 12 that can be mounted stationary in the vehicle, e.g. on the dashboard, on the center console or in the armrest, and a holding shell 14 designed as a so-called cradle, which is designed to hold a mobile phone 1 (see Fig. 2) and is specifically designed for the type of mobile phone used. The mobile phone holder with cradle 14 and base part 12 with the contact connectors 101, 111 has already been described above in connection with Figs. 7 and 8.

As shown in Fig. 9, the base part 12 is connected to an interface box 16 via a bus connection 22. The interface box 16 contains the so-called interface module, which is the central control unit of the entire mobile phone device including the hands-free and charging electronics. The interface box 16 is connected to the vehicle electrical system via an electrical connection (not shown) to control, among other things, the loudspeaker and microphone of the hands-free device and a speech recognizer. The vehicle electrical system can have a vehicle bus to which the hands-free device can be connected in order to communicate with other components via the bus. The interface box 16 is permanently mounted in the vehicle, e.g. behind or under the dashboard or in the trunk.

Not shown in Fig. 9 are the loudspeaker and the microphone of the hands-free system. These can be arranged separately in the vehicle. The microphone is preferably arranged in the upper area of the passenger compartment in the vehicle ceiling or in the area of the sun visor. The loudspeaker of the hands-free system can also be arranged separately in the passenger compartment; however, it can also be provided that the loudspeaker of the car radio serves as

The speaker of the hands-free system can be switched on and a microphone from the car radio system can also be used as a hands-free microphone.

The device is switched so that the hands-free mode is activated when the mobile phone is plugged into the cradle 14, i.e. the hands-free loudspeaker and the hands-free microphone are switched on. When the mobile phone is removed from the cradle 14 or the cradle is removed from the base unit 12, the system automatically switches from hands-free mode to private mode, in which the hands-free microphone and the hands-free loudspeaker are switched off and calls are made in private mode via the microphone and loudspeaker of the mobile phone.

As already mentioned, the mobile phone device in Fig. 1 is a hands-free device that can be used universally for various mobile phone types. For this purpose, the components permanently installed in the vehicle, i.e. the interface box 16 and the base part 12, are independent of the mobile phone type.

and remain installed unchanged when the mobile phone is replaced in the vehicle. Only the cradle 14, which preferably has mobile phone-specific software, is designed specifically for the mobile phone. The cradle 14 forms a connection unit that is designed specifically for the mobile phone and is therefore replaced when the mobile phone is replaced.
