Problems solved by technology

In some cases, there are space constraints for backplane slots and / or removable inserts as an improvement over legacy designs
Such space constraints can hinder the removal of removable inserts as there is little room to manually grasp the insert or to contain the extraction mechanism

example

[0051] combined reference Figures 3A-3C and Figure 4 In operation, insertion of the card 400 may cause a portion of the card 400 (such as the protrusion 422 ) to contact the protrusion 316 on the extraction lever 310 as the mating connector 410 of the card 400 engages the lower chassis connector 214 . During insertion of insert 400 , force applied to protrusion 316 by nub 422 may cause the outboard end of extraction rod 310 to rotate in a counterclockwise direction (eg, toward posterior / midplane 208 ). Counterclockwise movement of the outboard end of the extraction rod 310 may cause the actuation bar 320 to slide forwardly toward the posterior / midplane 208 along with the cam slot 322 . Forward movement of the actuator rod 320 and the cam slot 322 can cause the cam follower 332 to rotate the bell crank 330 . Such as Figure 3B As shown, bell crank 330 is rotatable in a counterclockwise direction, thereby causing connecting rod 340 to impart rotational motion to hook 350 . ...

Abstract

A retention-extraction device is provided for a removable card in a chassis. The device includes an actuation rod having a cam slot, the actuation rod configured to provide linear movement along the length of the actuation rod, and an extraction lever operatively connected to a proximal end of the actuation rod and pivotally secured to the chassis. The device also includes a bell crank with a cam follower that is configured to ride in the cam slot and a latch hook that pivots between an open and closed position based on the motion of the bell crank. The linear movement of the actuation rod causes the extraction lever to apply a force to a portion of the card and causes the latch hook to pivot to an open position to allow removal of the card.

Description

technical field [0001] The invention relates to a retaining-extracting device for a removable insert in a chassis. Background technique [0002] Electronic devices can be used in many types of systems and / or applications such as control systems, data processing systems, medical systems, telecommunications systems and / or communication networks. Electronic devices may include system controllers, servers, and / or network devices (eg, routers, switches, firewalls, and / or network address translators). For some applications, it may be desirable to make the electronics upgradeable to adapt to new application requirements. For example, communication networks may be expanded to accommodate new users, modified to accommodate new network protocols and / or types of data communications, and / or may be retrofitted in response to cyber attacks and / or natural disasters. [0003] Upgradable electronics can be designed to accommodate certain changes. For example, electronic devices may be con...
