Problems solved by technology

[0005] The main disadvantage of this aforementioned connection technique is that for each connection pin of the "TCU" that is to be further contacted, two soldering points have to be produced in each case.
In addition, the brazing joints often may not be produced at the same time and with the same brazing technique, resulting in high processing and cost outlays

Embodiment Construction

[0039] figure 1 The prior art electrical connection between a transmission controller soldered into a printed circuit board and flexible wiring paths is shown.

[0040] A through-sleeve 14 is inserted into the circuit board hole 10 of the circuit board 12 , and the connection pin 16 of the transmission controller 18 is welded into the through-sleeve 14 .

[0041] Every other electronic module or in-line packaging component configured as a structure capable of in-line packaging (so-called "THT"-component=" T through H ole T "technology"-component) can replace the transmission control device 18. In the interior of the circuit board 12 runs a printed conductor 20, which connects the connecting pin 16 to a metal contact pin 22 (so-called " Via") is electrically conductively connected. External electrical components of the automatic transmission, such as the pressure regulator 24 , are connected to the contact pins 22 via flexible wiring paths 26 , in particular conductor tracks...

Abstract

The invention refers to electric connection and a method for building the electric connection. The electric connection is established between an in-line package member which has at least one connection pin inserting into a circuit board penetrating sleeve on a circuit board and a soft cloth line path. Conductive connecting points are provided among the at least one connection pin of the in-line package member, the soft cloth line path and the penetrating sleeve. The electric connection enables a transmission control unit (TCU) with a plurality of connecting pins or connecting pins of any electric module to continuously touch with the soft cloth line path and to realize the electric connection between the connecting pins of the TCU and the penetrating sleeve in the electric board. The soft cloth line path is formed by printed wiring membranes which have a plurality of printed lines basically parallel with each other, uniformly extending at intervals and arranged among covering membranes. Accordingly each connecting pin only needs another one soldering joint which can meanwhile be established on a soldering side of the circuit board by any number and using a same soldering method, i.e., a selected soldering method.

Description

technical field [0001] The invention relates to electrical connections and methods for establishing electrical connections. Background technique [0002] In modern motor vehicles an ever-increasing number of system components are electronically adjusted and / or controlled. To optimize fuel consumption, for example, electronically controlled automatic transmissions are widely used. The electronic transmission controller (the so-called " T transmission C ontrol U nit"="TCU") with a large number of electronic and electrical components soldered into conventional circuit boards (so-called " P rinted C circuit B oard” = “PCB” and is enclosed in a sealed manner by the housing. Due to the hermetically sealed housing, the “TCU” can, for example, be placed directly in the transmission oil sump. The “TCU” contains often complex hybrid circuits, such as those constructed on ceramic substrates (so-called " L ow T temperature C of fire C eramic" = "LTCC"). [0003] In order to ...
