Antenna amplifier with connector between amplifier and line

0001The invention relates to a signal processing unit, in particular an antenna amplifier for a vehicle, according to the features of the preamble of claim 1.

0002From DE 196 05 999 A1 discloses a signal processing unit, in particular a Antenna amplifiers, known for a vehicle. This unit is in a certain disposed region of the body or a part thereof in the vehicle. From being are contacting available to antenna conductor patterns on a disk of the vehicle are applied to contact. About this contacting, eg Spring elements, the antenna conductor patterns on the wafer via electrical be Leads to the signal processing unit connected. For this purpose between the housing of the signal processing unit and the contacting means a boom available, the arm fixed to said housing signal processing unit is connected and spaced at its end the Contacting carries. The electrical supply line or the corresponding required Number of leads between the contacting means and the signal processing Unit are disposed on or in the cantilever arm and be pre-assembled in such a way that the housing of the signal processing unit with its cantilever arm (or several cantilever arms) with the contacting devices arranged at the end of a forming unit. Since such a unit in the production of the vehicle in this must be installed, it is necessary to have a fixed electrical connection make between the contacting means and the signal processing unit. This requires a complex construction of this entire preassembled unit brings one hand problems in the storage and the transport and on the other hand having tolerance problems, because the contacting means in this preassembled Unit always at predetermined points (contact points) of the antenna conductor structure have come to rest, which due to tolerances in the manufacture both of the preassembled unit and the contact points on the vehicle window is not the case. Moreover, during transport, the problem that the Extension arms with attached thereto contacting devices bend or can be damaged in any other way, whereby the entire cancel or Unit unusable. The same applies for the case that the entire unit in a Accident is damaged, so they must be replaced in their entirety.

0003The invention is therefore based on the object, a signal processing unit - as improve so that the disadvantages avoided - described at the outset will.

0004This object is achieved by the features of claim 1.

0005The invention is characterized in that the electrical lead signal processing at the Unit is removably disposed. This has the advantage that the signal-processing Unit separate from the contacting means via which the contact to the Antenna conductor structure is carried out, can be handled. Thus forming the signal processing Unit with its contacting means no complex unit more, but it can during production of the vehicle, the signal processing unit (or optionally also several) are mounted in the space provided, as well as the contacting means, so that both the signal processing unit as are also contacting arranged and fixed in position at the exact spot can, which are provided for them. Then, the mounting of the electrical carried Supply line to the signal processing unit, it is firstly possible that this electrical supply is arranged already fixed to the contacting means or also there, the electrical lead is detachably connectable to the contacting devices. There is thus the possibility of the electrical lead between the signal-processing Unit and the associated contact means removably attached to the signal-processing arranging releasably attached to the contacting devices unit and / or. About that is also possible, on the paths between the contacting means and the signal processing unit to provide more permanent connections.

0006The manner of the structure and contacting the contacting is arbitrary and can to the respective application, in particular the available installation space, be adapted. Similarly, various species come from electrical supply lines into consideration, in particular round cables, flat cables or . like It is important that in each case a contact point with a part of the antenna conductor structure is connected, via the contact means and the electrical Supply line can be connected to the signal processing unit.

0007Further embodiments of the invention, which give rise to beneficial effects, are given in the subclaims.

0008An exemplary embodiment, but to which the invention is not limited, is in the described below and illustrated in the figure.

0009The Figure shows in a schematic diagram of a signal processing unit 1, which is For example, is an antenna amplifier. This signal processing Unit 1 comprises, for example, a single- or multi-part housing 2, in particular a Plastic housing. Within the housing 2 is a printed circuit board 3 with this not shown electronic components and other accessories such as connectors and the like are disposed. Further, in the figure schematically a electrical supply line 4, whereby at the one end of the electrical feed line 4 Contacting 5 are available. comes to the structure of the contact means 5 it wherein the entirety is not attached, to mention sake, in this context, that these contact means 5, for example, as can be constructed as in Figures 2 to 4 (together with associated description) DE 196 05 999 A1 or in the Figures 1-4 of the patent application 103 16 384.0 disclosed. The contact means 5 and the electrical supply line 4 are in the region of the body part 6 of arranged vehicle, wherein the body part 6, for example, a metallic frame or body flange is, of a vehicle window receives. On this vehicle window antenna conductor structure is then applied or disposed therein, said to be contacted with the signal-processing unit 1 have portions of the antenna conductor structure contact points A, with the contacting devices 5 are associated.

0010To avoid the problems described is already envisaged that the the contacting means 5 opposite end of the electrical lead 4 removably attached to the signal processing unit 1 is arranged. With such a detachable connection is in particular to a connector 7, which consists of a socket 8 and made a plug 9, wherein at the end of the electrical supply line 4, the bush 8 and at the signal processing unit 1 of the connector 9 (or vice versa) is disposed. The Bush 8 and the connector 9 comprise interconnectable contact partners (the Plug 9 such as a contact partner 10, which is designed as plug pin) on. Here are at least as many contact partners in connector 7 available as it at full occupancy contacting 5 may supply. It is conceivable that each a contact means 5, a contact point A via a respective electric Lead 4 and an associated connector 7 with the signal processing unit 1 is connected. Moreover, it is also conceivable that a certain number one of contacting devices 5 over respective associated electrical leads 4 are socket 8 supplied and thus be centralized there to several contacting means 5 supply via a multi-pin connector 7 of the signal processing unit. 1

0011In the part of the connector 7 of the direct field of signal processing Unit 1, here, the male connector 9 is present, is an element which Part either of the circuit board 3, or only of the housing 2 or a Combination thereof. This means that in the circuit board with built-in the Housing 2 of the connector protrudes through a recess 9 in the casing 2 addition so that placed this signal processing unit 1 at its designated location and Then, the contacting of the electrical feed line 4 with the bush 8 by inserting it into the plug 9 can take place. This allows both the contacting means 5 as the signal processing unit 1 accurately and precisely at their designated Fitting place. In addition, it is also conceivable that the housing of the plug 9 (Or alternatively, the bushing 8) is not mounted on the circuit board 3, but Component of the housing 2, so that with the installation of the circuit board 3 with the there arranged contact partner is 10 until the complete connector 9 realized. About that , it is conceivable that parts of the connector 9, in particular the housing and its Partners, both part of components of the circuit board 3 and the Housing 2 and only the final assembly of the signal processing unit 1, the plug or the socket is realized.
