Abstract
Abstract A backplane has several socket connectors arranged in parallel, side by side, on a side facing the modules. The pins of the socket connectors form a pin field on a side of the backplane facing away from said modules. At least one bus consists of at least one bus line. Each bus contact pin of each socket connector of the bus is associated with a resilient contact pin. The resilient contact pins are each electrically connected by a spring force to the corresponding bus contact pin. The resilient contact pins are electrically connected by means of the bus line. The contact of each resilient contact pin can be separated with handling means formed from insulating material. Thus, modules can be separated from the bus without requiring that these modules be pulled out of their plug-in location on a module carrier.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
160 words
A backplane for a subrack having modules, comprising: a plurality of socket connectors arranged in parallel next to each other on a side of the backplane facing the modules; each of said socket connectors comprising a plurality of pins and bus contact pins on the side of the backplane facing away from said modules; said pins and said bus contact pins of said socket connectors together forming a pin field on the side of the backplane facing away from said modules; at least one bus having at least one bus line; a plurality of resilient contact pins corresponding to a bus contact pin of each socket connector, said resilient contact pins being electrically connected with spring force to said associated bus contact pin; said resilient contact pins of a bus being electrically interconnected with the bus line; and means for separating each of said resilient contact pins from its associated bus contact with a handling means made of insulating material.
Claim 2
Dependent Claim
160 words
A backplane for a subrack having modules, comprising: a plurality of socket connectors arranged in parallel next to each other on a side of the backplane facing the modules; each of said socket connectors comprising a plurality of pins and bus contact pins on the side of the backplane facing away from said modules; said pins and said bus contact pins of said socket connectors together forming a pin field on the side of the backplane facing away from said modules; at least one bus having at least one bus line; a plurality of resilient contact pins corresponding to a bus contact pin of each socket connector, said resilient contact pins being electrically connected with spring force to said associated bus contact pin; said resilient contact pins of a bus being electrically interconnected with the bus line; and means for separating each of said resilient contact pins from its associated bus contact with a handling means made of insulating material.
