Problems solved by technology
Soldered connections are vulnerable to mechanical loads, especially microscopic mechanical movements, and are therefore prone to failure
The plug-in connection wears out due to slight mechanical movements, so that an oxide layer can form and the ohmic resistance of the contact connection increases, so that the sensor signal can be influenced and distorted, and undesired contact interruptions can occur

Embodiment Construction
[0016] The contact connection module 1 according to the invention is in figure 2 are shown in an isolated or exploded view and in figure 1 fixed on the control housing 2. Contact connection module 1 according to figure 2 It has a lower housing 3 , a lead frame 4 and an upper housing 5 . The housings 3 , 5 are each designed as plastic parts, for example injection-molded parts, and are latched or clamped to one another, so that the housings 3 , 5 securely accommodate the metal leadframe 4 therein.
[0017] The lead frame 4 is produced in a known manner by punching out of sheet metal (eg copper) and has conductor tracks 4a and free ends 4b which are used for contact connections and are connected to each other via the conductor tracks 4a . The entire contact connection module 1 is used for the contact connection of the connected components, in particular the sensor 7 (for example a pressure sensor or travel sensor), the solenoid valve 6 and the control means (not shown here)...

The invention relates to a contacting module for a transmission controller, comprising: a module housing (3, 5), and a punched grid (4) made of metal, which is accommodated in the module housing (3, 5) and has several conducting tracks (4a) having free ends (4b), wherein contact surfaces (12) for contacting are formed at the free ends (4b). According to the invention, free spaces (10) are formed in the module housing (3, 5), said free spaces extending through the module housing (3, 5) in a vertical direction (v), at least some of the free ends (4b) are arranged at least partially in the free spaces (10), the contact surfaces (12) of at least some of the free ends (4b) extend substantially in the vertical direction (v), and at least some of the free ends (4b) are elastically yielding at least in the area of the contact surfaces (12) thereof.
Description
technical field [0001] The invention relates to a contact connection module for a transmission control part, which is used for contact connection between a solenoid valve and an electronic control device, preferably for a contact connection sensor. Furthermore, the invention relates to a production method for such a contact connection module and a transmission control module having such a contact connection module, as well as to a method for producing a transmission control module. Background technique [0002] Such a contact connection module is used as a component of the transmission control unit to undertake a variety of complex contact connections. In this case, the electronic control unit is connected in contact with the respective solenoid valve to be actuated and generally with sensors (eg acceleration sensors, rotational speed sensors, pressure sensors). [0003] The contact connection module is usually designed with a plastic housing and a circuit carrier, which in...
