Abstract
Abstract In a system for the programming of a measuring instrument which is installed in an automotive vehicle and has a front plate and a cover glass and within which an electric circuit is arranged, openings which are aligned with each other are provided in the front plate and the cover glass. Within the region of the opening there are provided in the front plate contacts which are connected with the electric circuit. The contacts can be formed of conductive paths of a circuit board which is arranged parallel to the front plate. A plug which can be introduced into the openings has axially resilient contact tips, at the end of the plug facing the circuit board, and it is provided with a device for locking the plug within the opening in the cover glass.

Claim 4
Dependent Claim
48 words
A system according to claim 1, wherein said contacts are formed of contact springs which are arranged on the circumference of an imaginary extension of an opening in the front plate; and wherein a spring force of said springs acts perpendicularly to an axis of the front-plate opening.
Claim 5
Dependent Claim
42 words
A system according to claim 3, further comprising a plug of substantially cylindrical shape which is introducable into the openings; and a plurality of longitudinally extending contact pieces which are arranged in a front portion on the outer surface of the plug.
Claim 6
Dependent Claim
27 words
A system according to claim 1, wherein said contacts are formed of conductive paths on a circuit board of said circuit arranged parallel to the front plate.
Claim 7
Dependent Claim
133 words
In a system for programming a measuring instrument installed in an automotive vehicle and having a front plate and a cover glass and within which an electric circuit is disposed, the improvement wherein said front plate and said cover glass are formed with openings aligned with each other, contacts are connected with the electric circuit and are arranged in a region of an opening in the front plate, said contacts are formed of conductive paths on a circuit board of said circuit arranged parallel to the front plate, a substantially cylindrically shaped plug which is introducable into the openings, said plug having axially resilient contact tips on an end of the plug, said end facing the circuit board, said plug including means for locking the plug in the opening within the cover glass.
Claim 8
Dependent Claim
133 words
In a system for programming a measuring instrument installed in an automotive vehicle and having a front plate and a cover glass and within which an electric circuit is disposed, the improvement wherein said front plate and said cover glass are formed with openings aligned with each other, contacts are connected with the electric circuit and are arranged in a region of an opening in the front plate, said contacts are formed of conductive paths on a circuit board of said circuit arranged parallel to the front plate, a substantially cylindrically shaped plug which is introducable into the openings, said plug having axially resilient contact tips on an end of the plug, said end facing the circuit board, said plug including means for locking the plug in the opening within the cover glass.
Claim 9
Dependent Claim
52 words
A system according to claim 6, further comprising an inner sleeve extending through said front plate; and each of the resilient contact tips is guided in said inner sleeve in a turning movement during an axial displacement of said contact tips, said system including spring means exerting a force against said displacement.
Claim 10
Dependent Claim
60 words
