## Abstract

A housing (1) with at least one electrical connection (7) through a housing wall (4) can be manufactured especially economically and can facilitate an especially economical lacing of electronic components (2, 13) present on the interior and on the exterior of the housing (1). The electrical connection (7) is enclosed by a housing material and additionally sealed by a sealing material (6). The sealing material (6) also advantageously serves to seal a top (3) and a bottom (5) to the housing wall (4). Through the combination of the casing of the electrical connection (7) of the housing (1) and the sealing material (6), this arrangement is, moreover, especially impervious to oil or other aggressive media.

## Claims

### Claim 1

A housing (1) for an electronic device, the housing comprising:
an electrical connection (7) communicating with the electronic device within an interior of the housing and extending to an exterior of the housing;
a double-walled housing wall one of fixedly encapsulating or surrounding the electrical connection (7);
a cavity in the housing wall (4), the electrical connection (7) passing through the cavity in the housing wall (4) to the exterior of the housing; and
a sealing material (6) located within the cavity for sealing the passage of the electrical connection (7), the sealing material (6) projecting from the cavity in the housing wall toward at least one of a housing top (3) and a housing bottom (5) and is sandwiched between the housing wall (4) and at least one of the housing top (3) and the housing bottom (5).

### Claim 2 (depends on 1)

The housing (1) according to claim 1, wherein the cavity Is defined by an area between the double-wall of the housing (1), the sealing material (6) being located within the cavity between the double-walls.

### Claim 3 (depends on 1)

The housing (1) according to claim 1, wherein the one or more of the top (3) and the bottom (5) are connected to the housing wall (4).

### Claim 4 (depends on 1)

The housing (1) according to claim 1, wherein the sealing material (6) forms a seal between one or more of the housing top (3) and the housing wall (4) and the housing bottom (5) and the housing wall (4).

### Claim 5 (depends on 1)

The housing (1) according to claim 1, wherein the one or more of the housing top (3) and the housing bottom (5) have a rotary bar (8), which presses into the sealing material (6) after the one or more of the housing top (3) and the housing bottom (5) have been connected to the housing wall (4), thus sealing the housing (1).

### Claim 6 (depends on 1)

The housing (1) according to claim 1, wherein the sealing material (6) that projects beyond the housing wall (4) in a direction toward the one or more of housing top (3) and the housing bottom (5) is utilized as an adhesive for connecting the one or more of the housing top (3) and the housing bottom (5) to the housing wall (4).

### Claim 7 (depends on 1)

The housing (1) according to claim 1, wherein the one or more of the housing top (3) and the housing bottom (5) are connected to the housing wall (4) via a snap lock (10).

### Claim 8 (depends on 7)

The housing (1) according to claim 7, wherein the one or more of the housing top (3) and the housing bottom (5) are one of glued and welded to the housing wall (4).

### Claim 9 (depends on 1)

The housing (1) according to claim 1, wherein the electrical connection (7) is a punch grid.

### Claim 10 (depends on 9)

The housing (1) according to claim 9, wherein the punch grid (7) has a housing of a plug connection (13) at an end located exterior of the housing, the housing wall (4) directly encapsulating and sleeving the plug connection (13).

### Claim 11 (depends on 1)

The housing (1) according to claim 1, wherein the electronic device is a transmission control of a motor vehicle.

### Claim 12

A method for manufacturing a housing (1) for an electronic device, the housing having an electrical connection (7) communicating with the electronic device within an interior of the housing and extending to an exterior of the housing, a double-walled housing wall one of fixedly encapsulating or sleeving the electrical connection (7), a cavity in the housing wall (4), the electrical connection (7) passing through the cavity in the housing wall (4) to the exterior of the housing and a sealing material (6) located within the cavity for sealing the passage of the electrical connection (7), the sealing material (6) projecting from the cavity in the housing wall toward at least one of a housing top (3) and a housing bottom (5) and being sandwiched between the housing wall (4) and at least one of the housing top (3) and the housing bottom (5), the method comprising the steps of:
inserting the electrical connection (7) into one of an injection mold and pressing mold, to one of encapsulate or sleeve the electrical connection (7) within a housing wall (4);
stuffing the sealing material (6) into the cavity of the housing wall (4) through which the electrical connection (7) passes; and
connecting the housing wall (4) to the one or more of the housing top (3) and the housing bottom (5).

### Claim 13 (depends on 12)

The method according to claim 12, further comprising the step of spraying a sealing lip (9) onto the housing wall (4).

### Claim 14 (depends on 12)

The method according to claim 12, further comprising the step of one of screwing, gluing, riveting and welding the housing wall (4) to the one or more of the housing top (3) and the housing bottom (5).

### Claim 15 (depends on 12)

The method according to claim 12, further comprising the step of one of directly encapsulating and sleeving a plug connection (13) to a punch grid (7), by the housing wall (4).

### Claim 16

A housing (1) for an electronic apparatus (2), the housing comprising:
a cover (3), a base (5) and a double-walled housing wall (4) that is arranged between the cover (3) and the base (5);
a cavity being formed between the two walls of the double-walled housing wall (4);
at least one electrical connection (7) extending through the housing wall (4) and the cavity from an interior side of the housing wall (4) to an exterior side of the housing wall (4) such that the at least one electrical connection (7) is either encapsulated or surrounded by the housing wall (4);
