Abstract

Abstract A transfer plug system for electrical or electronic controls or devices having coding parts which correspond to one another mechanically and are attached at a cable housing as well as in the area of a counter-plug element, the coding parts being brought into engagement with one another and held by means of a shared locking element, the locking element thus operating to fulfill a dual function of coding for preventing faulty plugging and of fastening and locking the plug housing at plates or in a structural component part carrier.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 191 words
A transfer plug system for a two-part coupling of electrical or electronic controls or devices, comprising: a guidance frame having a male multiplug connector equipped at least on one side side with recesses for receiving of coding pins; a cable housing with a female multipoint connector inside of said cable housing, said cable housing having two half-shell outer portions surrounding said female multipoint connector; coding connections being located on at least one outer side of the cable housing, said coding connections having breakaway bars which, after their removal, display openings; and coding pins, said coding pins having a clamp-shaped latch at one end and a cam at the other end, said coding pins being seated with one end in the recesses of the guidance frame of the male multipoint connector by means of said clamp-shaped latch and said cam which, after the connection of said coding pin is completed, engages behind a shoulder located on the outer side of one of the cable housing half-shell portions, said coding pins for providing a coding arrangement to prevent improper electrical coupling and for providing a latch arrangement to prevent disconnection of coupled devices.
Claim 2
Dependent Claim 191 words
A transfer plug system for a two-part coupling of electrical or electronic controls or devices, comprising: a guidance frame having a male multiplug connector equipped at least on one side side with recesses for receiving of coding pins; a cable housing with a female multipoint connector inside of said cable housing, said cable housing having two half-shell outer portions surrounding said female multipoint connector; coding connections being located on at least one outer side of the cable housing, said coding connections having breakaway bars which, after their removal, display openings; and coding pins, said coding pins having a clamp-shaped latch at one end and a cam at the other end, said coding pins being seated with one end in the recesses of the guidance frame of the male multipoint connector by means of said clamp-shaped latch and said cam which, after the connection of said coding pin is completed, engages behind a shoulder located on the outer side of one of the cable housing half-shell portions, said coding pins for providing a coding arrangement to prevent improper electrical coupling and for providing a latch arrangement to prevent disconnection of coupled devices.
Claim 3
Dependent Claim 27 words
A transfer plug system according to claim 1, wherein the width of the cam corresponds to the inside dimension of the breakaway parts of the coding connections.
Claim 4
Dependent Claim 41 words
A transfer plug system according to claim 1 or 2, wherein the coding connections and the shoulders coact with the cams of the coding pins, which coding connections are raised over the cable housing half-shells and are molded onto these half-shells.
