[0015] Finally, the invention provides that the interior of the power supply housing and / or the housing interior and / or a connection space in which the electrical connection between the electronic sub-assembly and the emergency power supply sub-assembly is arranged is sealed against the environment or the receiving space to at least protection class IP52 and, in particular, at least protection class IP56. This ensures that the assembly remains functional for as long as possible, even in the event of a vehicle accident or flooding, where the vehicle is subjected to increased stress from water ingress, in order to, for example, send emergency calls.

[0016] Further details of the invention are described in the drawing with reference to schematically illustrated embodiments.

[0017] This shows: Fig. 1: an exploded view of an embodiment of an assembly according to the invention; Fig. 2: the one in the Fig. 1 Emergency supply sub-assembly shown in side view; Fig. 3: a cut through the in the Fig. 2 emergency supply sub-assemblies shown; Fig. 4: a cut through the in the Fig. 1 shown assembly with emergency power supply subassembly mounted on the electronics subassembly; Fig. 5a-5c: based on the information in the Fig. Figure 1 shows a disassembly procedure for removing the emergency power supply sub-assembly from the electronics sub-assembly.

[0018] In the Fig. Figure 1 shows an exploded view of a variant of assembly 1. Assembly 1 comprises an electronics sub-assembly 101 and an emergency power supply sub-assembly 201. Assembly 1 is configured as a telematics box TB for a vehicle F.

[0019] The electronic subassembly 101 comprises an electronic housing 102, control electronics 103, and antennas 104a and 104b shown as examples. The control electronics 103 comprises a printed circuit board 105 and electronic components 106a and 106b shown as examples only. Furthermore, the control electronics 103 includes a multi-pin electrical connector 107, which is arranged on the printed circuit board 105.

[0020] According to one embodiment, it is also planned to arrange at least one antenna away from the circuit board and to connect it to the circuit board via electrical lines.

[0021] The electronics housing 102 comprises an upper housing part 102a and a lower housing part 102b, which, within a fully enclosed interior 102c, house the control electronics 103 and the antennas 104a, 104b. The housing 102 further includes a receiving compartment 108, designed in the form of a receiving pocket 109, which is intended for receiving the emergency power supply sub-assembly 201. The housing 102 has a recess 102d facing the receiving compartment 108, in which the connector 107 is arranged when the electronics sub-assembly 101 is assembled, so that its contacts 107a, 107b, 107c are accessible from the receiving compartment 108.

[0022] The emergency power supply sub-assembly 201 comprises an emergency power source 202, which consists of two accumulators, a power supply housing 203, and a mating connector 204, which is connected to the emergency power source 202 by means of a cable 205. The power supply housing 203 comprises a drawer-like storage box 203a and a lid 203b. The emergency power source 202 is housed in an interior compartment 203c. A recess 203d is formed on the wall side of the storage box 203a, in which the mating connector 204 is arranged when the emergency power supply sub-assembly 201 is assembled. Like the connector 107, this connector comprises three contacts 204a, 204b, and 204c. The lid 203b is bonded or welded to the storage box 203a in a watertight manner.

[0023] Assembly 1 further includes a seal 301. When assembly 1 is assembled, this seal 301 is positioned between the electronics sub-assembly 101 and the emergency power supply sub-assembly 201 such that it seals against both sub-assemblies 101 and 201 and forms a ring around an electrical connection 2 established between the sub-assemblies 101 and 201 via the connector 107 and the mating connector 204. This seals the connector 107 and the mating connector 204, as well as the recess 102d in the electronics housing 102 and the recess 203d in the power supply housing 203, against dust and moisture from the environment U (see also Fig. 4).

[0024] To retain the seal 301 during the assembly of the emergency power supply sub-assembly 201 on the electronics sub-assembly 101, the power supply housing 203 includes a retaining groove 203e extending ring-like around the recess 203d, which is designed as a cylindrical recess 206, against whose wall 206a and bottom 206b the seal 301 rests, which is designed as a sealing ring 301a (see also Fig. 2, Fig. 3 to Fig. 4).

[0025] On the electronic housing 102 of the electronic subassembly 101, an annular ridge 102e is formed around the recess 102d. The ridge 102e is adapted to the recess 206 and the seal 301 such that, when the assembly 1 is fully assembled, it dips into the recess 206 and presses the seal 301 against the bottom 206b of the recess 206. To achieve a good sealing effect, the seal 301 undergoes elastic deformation.

[0026] From a synthesis of Fig. Figures 1, 4, and 5a to 5c show that the supply housing 203 comprises a left first locking element 207a and a right first locking element 207b, which are formed on its cover 203b as opposing wings 208a, 208b that project laterally beyond the interior 203c. With these locking elements 207a, 207b, the supply housing 203 or the emergency power supply sub-assembly 201 interacts with a first left locking receptacle 112a and a first right locking receptacle 112b of the electronics sub-assembly 101 in a first locking direction z', forming a left locking device 302a and a right locking device 303b. Here, the locking devices 112a, 112b are formed behind ribs 111a, 111b projecting into the opposite mounting space 108 as left recess 113a and right recess 113b, respectively. As can be seen from a successive examination of the left, first locking device 302a based on the Fig. 5c, Fig. 5b and Fig. As can be seen in Figure 5a, the left wing 208a initially dips downwards in the z-direction to be guided under the left web 111a, whereby the left wing 208a is slightly deformed and the supply housing 203 is guided at a slight angle relative to the mounting direction x. As soon as the first, left locking element 207a, in the form of the left wing 208a, has passed the first left web 111a, it snaps upwards in the z'-direction, perpendicular to the mounting direction x, into the left, first locking receptacle 112a (see Figure 5a). Fig. 5b and Fig. 5a). In the locked position of the left and right first locking elements 207a, 207b, the mating connector 204 is also completely pushed onto the connector 107 and the seal 301 is clamped between the emergency power supply sub-assembly 201 and the electronics sub-assembly 101 (see Fig. 4). Here, the Fig. 4. With other cutting patterns, just like the... Fig. 5a the fully assembled assembly 1. In the Fig. 5b the supply housing 203 is already fully aligned in the receiving space 108 of the electronic housing 102, but the locking elements 207a, 207b are still elastically deformed.

[0027] Disassembly follows in reverse order with regard to releasing the first locking elements 207a, 207b, whereby a release pin 203f formed on the cover 203b of the supply housing 203 can be used to move the left and right, first locking elements 207a, 207b in the z-direction and thereby make it easier to release the locking mechanism.

[0028] Optionally, at least one second locking element is provided on the supply housing, wherein this second locking element is designed to interact with a second locking device formed on the electronics housing with a second locking receptacle in a second locking direction y or y'. In this case, unlike the first locking elements, the second locking element does not engage along a z-axis, but along a y-axis (see figure). Fig. 1), wherein the first and second locking directions are oriented perpendicular to the mounting direction x. Furthermore, the locking directions of the first and second locking elements are orthogonal to each other.

[0029] In the Fig. 5a to 5c in conjunction with the Fig. It can be seen that the supply housing 203 includes a beak-like guide element 210a on its left side wall 209a, which is formed by two ribs 211a, 211b converging towards each other in the opposite direction x of the assembly. A beak-like guide element 210b is also formed on a right side wall 209b, mirror-symmetrical to an xz-plane that divides the emergency supply sub-assembly in the middle. On the electronics housing 102, a guide element 210a is located on a left side wall 114a of the receiving space 108 (see Figure 1). Fig. 1) a rail-like counter-guiding element 115a (see Fig. 5a to 5c). The counter-guide element 115a has different hatching patterns because it is formed by the upper housing part 102a and the lower housing part 102b. A rail-like counter-guide element 115b is also formed on a right side wall 114b of the receiving space 108, mirror-symmetrical to an xz-plane that bisects the electronic sub-assembly 101. The guide element 210a and the counter-guide element 115a form a left cam guide 3a. The guide element 210b and the counter-guide element 115b form a right cam guide 3b, which is hidden in all illustrations.

[0030] From the presentation of Fig. Figure 2, which shows a side view of the emergency power supply sub-assembly 201 towards the recess 203d, shows that the two guide elements 210a and 210b diverge in the opposite direction of assembly x, i.e., into the plane of the drawing, and conversely, in the direction of assembly, i.e., out of the plane of the drawing, they approach each other. The counter-guide elements 115a and 115b (see Figure 2) Fig. 1 and 5a to 5c) exhibit a comparable profile, so that when the emergency power supply sub-assembly 201 is inserted into the receiving space 108, the emergency power supply sub-assembly 201 is increasingly centered on the electronics sub-assembly 101. This ensures that the mating connector 204 is precisely aligned with the connector 107 during assembly and is pushed onto it without tilting.

[0031] The emergency power supply sub-assembly 201 is mounted using a combined sliding swivel movement SSB (see Fig. 5c), wherein the emergency power supply sub-assembly 201 is first slid onto the electronics sub-assembly at a slight angle to the mounting direction x and finally a slight pivoting movement about the area shown in the Fig. The movement 5c into the y-axis, which is perpendicular to the drawing plane, guides the ratchet elements 207a and 207b into the detent receptacles 112a and 112b. The mating connector 204 is elastically or floatingly mounted on the supply housing 203 so that the sliding pivoting movement SSB does not cause it to tilt with the connector 107. Disassembly is performed accordingly with a reverse movement, namely a pivoting sliding movement SSB'.

[0032] From the Fig. 2, Fig. 3 to Fig. Figure 4 shows how the seal 301 is received in the cylindrical recess 206 and how the annular ridge 102e of the electronics housing 102 presses against the seal 301 in the fully assembled state of the assembly 1, and how both the interior 102c of the electronics housing 102 and the interior 203c of the supply housing are sealed to their respective recesses 102d and 203d by the sealing ring 301 in the area of ​​the electrical connection 2 or the connector 107 and the mating connector 204 from the environment U. Fig. 4 a connecting space 4 is also recognizable, which is arranged between the housing interior 102c of the electronic housing 102 and the interior 203c of the supply housing 203 and accommodates the electrical connection 2.

[0033] As from the Fig.As can be seen in Figure 1, the electronics housing 102 has the external dimensions of a cuboid, defined by a length L102, a height H102, and a width B102. These external dimensions are independent of whether the power supply housing 203 is included in the electronics housing 102 or not.
