Displaceable card guide for high packing ratio housings
View Patent ↗Displaceable card guides for use with high packing ratio housings for network tap modules. The housing allows the user to maintain all network taps in any given system in one housing and location. This increases the ease of maintaining multiple network taps and allows the network tap modules to be powered by a power supply included with the housing. The displaceable card guides enable a set network tap modules to be housed in a single housing with negligible or no spacing between adjacent modules. In addition, these card guides the associated housing are generally applicable to a number of other types of modular electrical or optical components.
1. A displaceable card guide for use with a high packing ratio housing for pluggable modular components, comprising:
a base attached to a top wall of the housing;
a guide member having a guide surface that is in contact with a pluggable modular component when the pluggable modular component is received in the housing; and
two retractable arms, wherein a first end of each of the two retractable arms is attached to the base and a second opposite end of each of the retractable arms is attached to the guide member, the two retractable arms permitting the guide member to displace toward the base so as to move the displaceable card guide from a extended position to a retracted position when the pluggable modular component is received in the housing.
2. A displaceable card guide as recited in claim 1 , further comprising a lateral surface that operates, when the displaceable card guide is in the extended position, to constrain lateral motion of an adjacent pluggable modular component as the adjacent pluggable modular component is inserted into a position adjacent to the displaceable card guide.
3. A displaceable card guide as recited in claim 1 , wherein the guide member has a sloped leading edge.
4. A displaceable card guide as recited in claim 3 , wherein the sloped leading edge contacts the pluggable modular component as the pluggable modular component is received in the housing and translates motion of the pluggable modular component that is substantially parallel to a long axis of the guide member into a force that moves the displaceable card guide to the retracted position.
5. A high packing ratio housing having a plurality of displaceable card guides, comprising:
a chassis having an opening with a plurality of positions that each can receive a pluggable modular component;
a power supply at least partially disposed within the chassis and connectable to a pluggable modular component; and
a plurality of displaceable card guides, each card guide corresponding with one of the positions and including:
a base attached to the inside roof of the chassis;
a guide member having a guide surface that is in contact with the pluggable modular component when the pluggable modular component is received in the housing; and
two retractable arms, wherein a first end of each of the two retractable arms is attached to the base and a second opposite end of each of the retractable arms is attached to the guide member.
6. A high packing ratio housing as recited in claim 5 , wherein the two retractable arms permit the guide member to displace toward the base so as to move the displaceable card guide from an extended position to a retracted position when the pluggable modular component is received in the housing.
7. A high packing ratio housing as recited in claim 6 , wherein each of the plurality of displaceable card guides includes a lateral surface that operates, when each displaceable card guide is in the extended position, to constrain lateral motion of an adjacent pluggable modular component as the adjacent pluggable modular component is inserted into a position adjacent to the displaceable card guide.
8. A high packing ratio housing as recited in claim 5 , wherein the plurality of displaceable card guides comprises eleven displaceable card guides.
