Insertion/Extraction Mechanism, Mechanically Assisted, Low Profile, Spring-Loaded

Disclosed is a method for inserting, extracting, and retaining various devices, including power supplies, add-in cards, and docking modules. Benefits include a solution that is intuitive and easy to use.

Background

The disclosed method is useful for inserting, extracting, and locking Hot Plug Memory modules in a multi-processor server.

General Description

The disclosed method consists of a handle, two symmetric levers, a spring element (which can be integrated into the handle), a latching mechanism (which can be integrated into the handle), and a carrier (see Figure 1).

The carrier is the backing plate for a card that must be inserted and extracted. This carrier could also be the side wall of a power supply or other device that needs mechanically assisted insertion and integrated latching. The user pushes on the handle to install the device, and pulls on the handle to extract the device. The linear motion of the handle is converted to a rotational motion of the levers via a cam in the handle and lever. The levers have a separate fixed-pivot joint. These levers engage fixed features in the assembly (e.g. an opening in the side wall) that the device is being inserted into. The levers apply a load on these fixed features that overcomes the mating force or disengaging force of the connector or other resistance. The geometry of the lever and the amount of handle-travel determines the amount of mechanical advantage that can be achieved.

The disclosed method has a two-to-one advantage over a mating...
