US5037313A — Active plug-in function unit

Claim 1

Independent Claim 175 words

An active plug-in function unit intended to be plugged into a multipolar plug contact device mounted on a circuit board or a back plane, said function unit comprising: a base plate; a connector; an electronic circuit; and a cover, wherein said connector includes a module-type multipolar sleeve connector mounted on one end of said base plate and forms a mechanically separable electrical interface between said function unit and the circuit board or back plane, wherein said base plate extends in a direction in which said sleeve connector extends, wherein said electronic circuit is mounted on said base plate and is connected to said sleeve connector, wherein a cover is mounted over said electronic circuit and forms together with said base plate and said connector and EMC-screen around said circuit, and wherein a geometrical projection of said function unit onto a plane of a face of the plug contact device, when said function unit is plugged into the circuit board or the back plane, falls within the dimensions of the face of the plug contact device.

Claim 2

Dependent Claim 175 words

An active plug-in function unit intended to be plugged into a multipolar plug contact device mounted on a circuit board or a back plane, said function unit comprising: a base plate; a connector; an electronic circuit; and a cover, wherein said connector includes a module-type multipolar sleeve connector mounted on one end of said base plate and forms a mechanically separable electrical interface between said function unit and the circuit board or back plane, wherein said base plate extends in a direction in which said sleeve connector extends, wherein said electronic circuit is mounted on said base plate and is connected to said sleeve connector, wherein a cover is mounted over said electronic circuit and forms together with said base plate and said connector and EMC-screen around said circuit, and wherein a geometrical projection of said function unit onto a plane of a face of the plug contact device, when said function unit is plugged into the circuit board or the back plane, falls within the dimensions of the face of the plug contact device.

Claim 3

Dependent Claim 35 words

A unit according to claim 1, wherein said base plate is provided, in the region of said electronic circuit, with cooling fins which project out at right angles in a direction opposite to said circuit.

Claim 4

Dependent Claim 32 words

A unit according to claim 1, wherein said cover is provided with a recess which extends transversely across said unit and which functions to form a cooling-air channel within said function unit.

Claim 5

Dependent Claim 28 words

A unit according to claim 1, wherein said electronic circuit includes a substrate or a circuit board glued on said base plate and connected to said sleeve connector.

Claim 6

Dependent Claim 13 words

A unit according to claim 4, wherein said electronic circuit includes a DC/DC-rectifier.

Claim 7

Dependent Claim 35 words

A unit according to claim 1, wherein said base plate includes on a side thereof opposite to said sleeve connector a connecting means which forms a mechanically separable interface to an incoming or outgoing cable.

Claim 8

Dependent Claim 19 words

A unit according to claim 6, wherein said electronic circuit includes a signal-adapting converter such as an opto-electrical converter.

Claim 9

Dependent Claim 18 words

A unit according to claim 6, wherein said electronic circuit includes a signal filter and/or a signal protector.

Claim 10

Dependent Claim 37 words

A unit according to claim 1, wherein said base plate includes an extension which extends from said sleeve connector and which functions as a cooling flange and as a handgrip from facilitating handling of said function unit.

Claim 11

Dependent Claim 14 words

A unit according to claim 4, wherein said electronic circuit includes a power filter.

Claim 12

Dependent Claim 168 words

An active plug-in function unit for plugging into a multipolar contact device mounted on a circuit board, comprising: a base plate; a connector, said connector including a module-type multipolar sleeve connector mounted on one end of said base plate and forming a mechanically-separable electrical interface between said function unit and the circuit board; an electronic circuit board mounted on said base plate and connected to said sleeve connector; and a cover, said cover being mounted over said electronic circuit and forming, together with said base plate and said connector, an EMC-screen around said electronic circuit, wherein said base plate extends in a direction in which said sleeve connector extends, and includes an extension which extends from said sleeve connector and which functions as a cooling flange and as a handgrip for facilitating handling of said function unit, said extension being bent to an angle at its outer end to form a grip flange, said grip flange including a lead-through guide for a cable connected to said function unit.

Claim 13

Dependent Claim 168 words

An active plug-in function unit for plugging into a multipolar contact device mounted on a circuit board, comprising: a base plate; a connector, said connector including a module-type multipolar sleeve connector mounted on one end of said base plate and forming a mechanically-separable electrical interface between said function unit and the circuit board; an electronic circuit board mounted on said base plate and connected to said sleeve connector; and a cover, said cover being mounted over said electronic circuit and forming, together with said base plate and said connector, an EMC-screen around said electronic circuit, wherein said base plate extends in a direction in which said sleeve connector extends, and includes an extension which extends from said sleeve connector and which functions as a cooling flange and as a handgrip for facilitating handling of said function unit, said extension being bent to an angle at its outer end to form a grip flange, said grip flange including a lead-through guide for a cable connected to said function unit.
