In general, the present invention relates to a device in a portable radiotelephone which can be remotely controlled by an external auxiliary unit, for example mounted in a vehicle.

A conventional radio telephone is carried, for example, by the police in a shoulder bag. The telephone is controlled by means of a remote control unit which is attached, for example, to the turn of the jacket and which is surrounded by a housing which is so small that it can fit in the hand. The housing includes, for example, a microphone, a loudspeaker and a transmit / receive switch.

When the police are driving the car, the radio is connected to an additional unit attached to the car, which consists, for example, of a car radio antenna, a power amplifier. tin stage, steering wheel-mounted transmit / receive switch, separate loudspeaker and microphone permanently installed in the car, fixed channel selector switches arranged in the same panel in one position. with volume control, selective call system, etc.

The connection from the radiotelephone to the auxiliary unit is made by the police removing 2,58237 from the shoulder bag of the radiotelephone and placing the telephone in a cassette equipped with a control panel from which it is now possible to control the radiotelephone.

However, this is time consuming and in many cases a particularly cumbersome task, as you must first detach the phone from the shoulder bag and then fit the entire phone, which can be relatively heavy, into the cassette at a predetermined location.

The invention aims to eliminate this drawback and provides a simple, fast and reliable way to connect a portable radiotelephone to, for example, an automated external external unit, from which the entire radiotelephone can then be remotely controlled.

In one aspect, the invention refers to a remote control unit for controlling the functions (e.g., microphone operation, loudspeaker operation, and transmit / receive switch) of a portable radio transmitter including a transmitter and receiver unit, which remote control unit is built into a hand-held or jacket-mounted radio housing, of which This remote control unit is characterized by a connector embedded in the housing with connection terminals, which allows the desired number of radiotelephone functions (eg microphone operation, loudspeaker operation, transmission / reception switch, handover, battery * charging, selective calling, etc.) to be controlled remotely. an extension unit, which together with the antenna form a plug-in unit for connecting the entire radiotelephone to an external extension unit.

The invention, on the other hand, means an additional unit which is, for example, installed in a car for use in conjunction with a remote control unit such as that described. This auxiliary unit has a set of operation and / or control units (eg microphone, loudspeaker, transmit / receive switch, channel selector, volume control, etc.) for the radio functions that you want to remotely control from the auxiliary unit. The auxiliary unit is characterized by a holder for a plug unit embedded in the panel, the holder comprising a contact element for a connector, and an inlet for the antenna.

It is thus possible for the police to simply insert the plug unit into the panel, so that the radio telephone can be remotely controlled from the auxiliary unit without having to detach the radio telephone itself from the shoulder bag.

The invention will be described in more detail below with reference to the accompanying drawings, in which

Fig. 1 shows a plug unit and holder according to the invention, and

Fig. 2 shows a simplified circuit diagram of the functions that can be remotely controlled by the auxiliary unit when the plug-in unit is connected to the holder.

In the drawing, an invisible radiotelephone, for example carried "by a belt", is controlled by a remote control unit 1. The number of remote control functions is in principle arbitrary. The remote control unit is housed in a housing 2 which is so small that it can mainly fit in the hand. The remote control unit in the drawing has a microphone and a loudspeaker built into the housing, and the transmit / receive switch 3 is on the other side of the housing, and the cable 4 connects the remote control unit to a radio telephone equipped with a transmitter. and a receiver tuned to UHP or VHP frequencies.The antenna 5, which is of the so-called helix type, is on top of the housing.The antenna is about 8-10 cm long and consists of a copper coil coated with rubber or the like.The connector 6 is placed on the main wall. The connector has a set (in drawing 8) of terminals 7 which make it possible For example, the radio can be remotely controlled from an external extension 8. The number of remotely controlled functions is in principle unlimited. First, the connector 6 may be a female-type contact connector. The antenna 5 together with the connector 6 form a plug-in unit for a radiotelephone. The plug-in unit is intended to be connected, for example, to a car-mounted auxiliary unit 8 with a holder 10 for a plug-in unit recessed in the panel 9. The holder has a contact unit 11 for connector 6 and an inlet 12 for antenna 5. The contact element is, for example, of the male type suitable for female-type poles 7. There is a spiral 12 around the input opening (cf. Fig. 2) which inductively connects antenna 5 to an external antenna, for example a car antenna 15, in Fig. 1 via a power amplifier 14 (shown in Fig. 2). there is also a volume control and channel change switches not shown separately.

When the remote control unit 1 is carried in a jacket turn, it acts as a loudspeaker, a microphone and a transmit / receive switch. When the control unit instead acts as a plug unit, i.e. is placed in the holder 10, the loudspeaker, microphone and transmit / receive switch functions are switched off and replaced by corresponding elements belonging to the auxiliary unit. Functions other than those included in the remote control unit 1 are transferred to the auxiliary unit when the plug unit is inserted.

As can be seen from the simplified wiring diagram shown in Fig. 2, in addition to the antenna 15, the car microphone 16, which is supplied via the power amplifier 17, the microphone 18 and the steering wheel-mounted transmit / receive switch 19, the radio unit can be charged via the radio , selective call via input 22, etc. The number of functions by which the auxiliary unit can remotely control the radiotelephone is thus in principle unlimited, and the number does not have to be selected on the basis of any special rule.

The modes of operation described above can be changed and varied in many ways within the basic idea of the invention.
