Problems solved by technology
In principle, such seals have proven useful, but are relatively time-consuming and expensive to manufacture
Additionally, it is relatively difficult to determine the exact amount of sealant for the cavity between the lid and base plate during manufacturing
If the amount of sealant is too low, there is a risk of an unsafe seal
If the amount of sealant is too large, there is a risk of damaging the controls, as the sealant is squeezed out when the cover is placed

Embodiment Construction
[0026] figure 1 A schematic cross-section of a carrier assembly 1 according to a first preferred embodiment of the invention is shown. The carrier assembly is part of the housing of the vehicle control unit.
[0027] The carrier assembly 1 comprises a main body 2 which is an injection molded body. A through hole 3 is formed in the main body 2 . The main body 2 has a first outer side 21 and a second outer side 22 . The first outer side and the second outer side are substantially parallel to each other.
[0028] The carrier assembly 1 also comprises an insert 5 which in this embodiment has a rectangular cross-section. The insert 5 is the part for current conduction, preferably entirely made of copper.
[0029] In particular, from Figure 2 to Figure 4 As can be seen in , the insert 5 extends through the through hole 3 . In this case, the insert 5 extends transversely to the opening direction of the through-hole 3 .
[0030] From figure 2As can be seen in , the insert 5...

The invention relates to a carrier assembly, in particular a housing assembly of a control device, comprising: a main body (2) with a through hole (3), a first outer side (21) and a second outer side (22); an insert (5) , is only partially surrounded by the material of the body (2) and extends through the through-hole (3) transversely to the opening direction of the through-hole; wherein the insert is arranged in the through-hole (3) such that the insert (5) The upper side (50) has a first distance (A1) to the first outer side (21), and the lower side (51) of the insert (5) has a second distance (A2) to the second outer side (22); by A first sealing element (7) made of a first material, which is arranged in the through-hole (3) and in direct contact with the insert (5); a second sealing element made of a second material (8), the second sealing element is arranged in the through hole (3) and directly contacts the insert (5); wherein the first sealing element (7) and the second sealing element (8) are in the through hole (3). The contact areas (9) in the holes (3) touch each other and completely surround the insert (5) in its circumferential direction.
Description
technical field [0001] The present invention relates to a carrier assembly, in particular a housing assembly or the like for a motor vehicle control device with improved sealing, as well as to such a control device and a method of manufacture. Background technique [0002] Carrier assemblies are used in automotive control units or the like, which usually have copper-based inserts which are encapsulated by plastic. In this case, the insert is used to produce an electrical connection (for example an electrical terminal) of the electronic components arranged inside the control device to the outside world. Since the insert is led out of the carrier assembly, there is the risk, in particular in the event of temperature changes (eg sudden cooling), that a negative pressure develops inside the control device. Due to this negative pressure there is a risk that harmful media, such as saline or other liquids, acting on the outside of the control, enter the interior of the control alo...
