Electric plug-in connection system
An electric plug-in connecting system having at least one contact device and an electric plug-in connector for electrically connecting the electric plug-in connector with the contact device, and having a coding system to avoid unintentional contacts, wherein the coding system includes at least three coding devices independent of one another for coding.
1. An electric plug-in connecting system comprising:
a contact device including at least two tower sockets;
an electric plug-in connector including at least two projecting towers configured to be electrically connected to said at least two tower sockets of said contact device, and
a coding system associated with said at least two tower sockets and said at least two projecting towers to avoid unintentional contacts, said coding system comprising at least three independent coding devices each configured for guiding connection of said at least two tower sockets and said at least two towers in a single orientation,
two of said coding devices being on a wall forming said at least one tower socket and an outer wall of said at least one projecting tower; and
the other of said coding devices inserted in said contact device or said connector in different orientations.
2. The electric plug-in connecting system according to claim 1 , wherein the contact device is configured as a master strip.
3. The electric plug-in connecting system according to claim 1 , wherein the plug-in connector is configured as a plug.
4. The electric plug-in connecting system according to claim 1 , wherein said other of said coding devices is configured to be inserted in said contact device in a first orientation and inserted in said connector in a second, different orientation, which is 180 degrees from the first orientation.
5. The electric plug-in connecting system according to claim 1 , wherein the coding system comprises a coding contour device as a coding device which is formed by mated, asymmetric housing geometries of the tower sockets of the contact device and of the towers of the electric plug-in connector.
6. The electric plug-in connecting system according to claim 5 , wherein the tower sockets of the contact device and/or the towers of the plug-in connector are non-symmetric in contour.
7. The electric plug-in connecting system according to claim 5 , wherein the towers of the plug-in connector are rectangular in their outer contour and have at least one coding chamfer.
8. The electric plug-in connecting system according to claim 1 , wherein the coding system comprises at least one key and keyway coding device as the coding device.
9. The electric plug-in connecting system according to claim 8 , wherein the key and keyway coding devices at the plug-in connector and at the contact device each comprise at least one coding key and one coding keyway.
10. The electric plug-in connecting system according to claim 8 , wherein the key and keyway coding devices at the plug-in connector and at the contact device each comprise the same number of coding keys and coding keyways.
11. The electric plug-in connecting system according to claim 1 , wherein the coding system comprises a coding profile device as the coding device comprising at least one coding socket and at least one exchangeable coding profile.
12. The electric plug-in connecting system according to claim 11 , wherein two or more coding sockets and at least one coding profile are provided.
13. The electric plug-in connecting system according to claim 11 , wherein at least one coding profile is configured T-shaped and wherein when installed as intended a leg of the T-shaped coding profile protrudes out of the coding socket.
14. An electric plug-in connecting system comprising:
a contact device including at least two contour receptacles; and
an electric plug-in connector including at least two protruding keyways, said at least two protruding keyways and said at least two contour receptacles being configured to matingly engage each other, wherein each said at least two protruding keyways and said at least two contour receptacles include a coding system having at least three independent coding devices for guiding connection of said contact device and said plug-in connector in a single orientation,
two of said coding devices being on a wail forming said at least two contour receptacles and an outer wall of said at least two protruding keyways; and
the other of said coding devices being inserted in said receptacle or said connector in a first orientation relative to said receptacle or said connector, and a second, different orientation relative to said receptacle said connector.
