Benefits of technology

The present invention provides an improved cable bushing that is easy to assemble at a control housing and provides better contact between the cables and printed circuit board. The cable bushing is made of a one-piece bushing housing body with passages for the contact elements and sealing elements, which can be easily manufactured. A cap with resilient projections can be latched onto the bushing housing body to ensure a good sealing of the cable within the bushing housing body.

Problems solved by technology

The cables laid within the housing could moreover be squeezed during subsequent assembly operations within the control housing which can lead to cable breaks.
The previously known bushings do not fulfil these requirements sufficiently.

Embodiment Construction

[0038]FIG. 1 shows a perspective side view of an exemplified embodiment of a cable bushing housing 2 for a cable bushing according to the invention. The cable bushing housing 2 is in the present case embodied in two pieces and has a bushing part 4 and a retainer part 6 which are connected to each other with the interposition of a shielding plate 8. The bushing part 4 forms a flange 10 which forms a locating surface 12 for placing it against a not represented control housing. The locating surface 12 is provided with a circumferential groove 14 into which a sealing ring 16 is inserted.

[0039]The shielding plate 8 shown in a perspective view in FIG. 3 has several bores penetrating a flat shielding surface 18 of which one central bore is designated with reference numeral 20. The lateral bores designated with reference numeral 22 are shaped as female plug element retainers. The lateral fastening bores are provided on the opposite side and are designated with reference numeral 24. They are...

Abstract

A cable bushing is disclosed for placement into a control housing surrounding a printed circuit board. The cable bushing includes a bushing housing comprising a locating surface, fastening means for fastening the bushing housing to the control housing, and retainers for at least two cables which are to be electrically connected to the printed circuit board. To facilitate the assembly of the cable bushing, the cable bushing housing is provided with contact elements that protrude from its front face, that are embodied to be adapted for plug contacting the printed circuit board, and that are electrically connected to the associated cables within the bushing housing.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention relates to a cable bushing disposed a control housing surrounding a printed circuit board. The cable bushing has, in a manner known per se, a bushing housing comprising a locating surface to abut against a control housing in a sealing manner, and preferably fastening means for fastening the bushing housing to the control housing. Furthermore, the bushing housing includes retainers for at least two cables to be electrically connected to the printed circuit board.2. Description of the Related Art[0002]Such a cable bushing usually has a bushing housing formed of plastics or another insulating material which is penetrated by retainers guiding the cable from the outside to the inside of the control housing. In prior art, the cable sheath of the cable within the bushing housing is partially removed, for example to expose a shielding of the cable in the region of the bushing housing and to electrically apply it...
