Abstract
Abstract The coder device prevents plugs being assembled to a counter-plug device having a different coding. The coder device is formed by tongue-like projections on a plug and by corresponding chamber-like recesses on the counter-plug device. The projections are provided with a theoretical breakage point and can be broken off. The broken off projections can be inserted into the associated recess of the housing of the counter-plug device. By breaking off projections in different combinations, it is possible to individualize the original universal coder device.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
95 words
A multi-pole electric plug connection with a coder device, comprising a plug and an associated counter-plug device pluggable together in a plug-in direction to form the plug connection, said plug being provided with integrally formed projections, pointing in the plug-in direction, and said counter-plug being provided with corresponding recesses into which the projections frictionally engage in the assembled state, wherein selected projections can be broken off at a theoretical breakage point from the plug and can be inserted into and held in the associated corresponding recess in the counter-plug to provide a specifically coded plug.
Claim 2
Dependent Claim
95 words
A multi-pole electric plug connection with a coder device, comprising a plug and an associated counter-plug device pluggable together in a plug-in direction to form the plug connection, said plug being provided with integrally formed projections, pointing in the plug-in direction, and said counter-plug being provided with corresponding recesses into which the projections frictionally engage in the assembled state, wherein selected projections can be broken off at a theoretical breakage point from the plug and can be inserted into and held in the associated corresponding recess in the counter-plug to provide a specifically coded plug.
Claim 3
Dependent Claim
30 words
A plug connection as claimed in claim 1, wherein the projections are injection molded, in the form of tongues, to said plug and are provided with a groove-type breakage constriction.
Claim 4
Dependent Claim
17 words
A plug connection as claimed in claim 1, wherein the recesses represent chambers in the counter-plug device.
Claim 5
Dependent Claim
17 words
A plug connection as claimed in claim 1, wherein the broken-off projections are clamped in the recesses.
Claim 6
Dependent Claim
79 words
A multi-pole electric plug connection with a coder device, comprising: a plug having a housing with a plurality of integrally formed projections extending in a plug direction; a counter-plug having a housing with a plurality of recesses which are frictionally matable with said plug projections; said projections being individually removable from said plug housing and insertable into said recesses in said counter-plug housing to be frictionally held therein; whereby, said plug can be specifically coded to said counter plug.
Claim 7
Dependent Claim
79 words
A multi-pole electric plug connection with a coder device, comprising: a plug having a housing with a plurality of integrally formed projections extending in a plug direction; a counter-plug having a housing with a plurality of recesses which are frictionally matable with said plug projections; said projections being individually removable from said plug housing and insertable into said recesses in said counter-plug housing to be frictionally held therein; whereby, said plug can be specifically coded to said counter plug.
Claim 8
Dependent Claim
27 words
A plug connection according to claim 5, wherein said projections are provided with a detachment means to facilitate manual removal of said projections from said plug housing.
Claim 9
Dependent Claim
18 words
A plug connection according to claim 5, wherein the removed projections are clamped in said counter plug recesses.
