Description

Board card insertion-assisting and pulling-assisting mechanism

Technical Field

The invention relates to a board card plugging and pulling assisting mechanism capable of providing high plugging and pulling force, in particular to a board card plugging and pulling assisting mechanism capable of playing a role of high plugging and pulling force in a closed narrow space.

Background

Some products adopt small-sized closed cabinets and are designed in a modular manner due to special application occasions, so that the maintainability of equipment is emphasized. The main board as the core of the system has a plurality of high-speed signal connections with the back board, and in order to ensure the signal connection reliability, a 2mm ERmet Hard Metric connector of ERNI is adopted in the design. The connector is specially designed for high-speed signals, gold is plated on the surface, and the connector is tightly contacted with a socket, so that the connection reliability is ensured; and the pins are dense, so that connection with sufficient density is provided for mass data communication in a narrow space. However, there are problems associated with this, as follows:

1. the plugging force caused by the high-density socket is extremely high, taking the ERNI socket as an example, the pins are slender, and the diameter of a single needle is only about 0.6 mm; the pin array is dense, each socket has 7x 22-144 pins, and the depth of the pin array inserted into the female socket is long. The standard CPCI motherboard requires 5 sockets and 700 pins, and the plugging force of the Connector is about N X0.75.75N (N is the number of pins) as known from the technical manual of ERNI (2.0mm ERmet Hard Metric Connector System P.156), and the calculation shows that the Connector requires about 5 sockets and 700 pins

The insertion and extraction force of 5 sockets is 22X 7X 0.75N X5 ═ 577.5N

Converted into kilogram number 577.5N/9.8 ≈ 59Kg

The force is completely beyond the normal pulling force provided by an adult arm;

2. the case is small in size and not beneficial to plugging and unplugging operation, due to the fact that the space of the case is limited, maintenance operation is conducted after the equipment is installed and formed, force application space is not available completely, and the products emphasize maintainability of the equipment and require the capability of being quickly replaced and maintained on site.

3. Because the socket needs extremely large insertion and extraction force and the cabinet space is narrow, if violent jerking is adopted, the pins are easy to bend and break, which causes serious consequences.
