It's about memory modules.

Generally, a connector refers to an electronic component that electrically connects between a power source and a device, a device to a device, or internal units of a device.

There are several types of connectors depending on their shape and connection method, such as connecting a cable to the connector or directly inserting it into a printed circuit board.

A socket connector and a plug connector can be combined to transmit signals, and are generally composed of contacts (terminals), an insulating material that protects the terminal and prevents short-circuiting with the adjacent terminal, and an exterior (shell).

In particular, aircraft use avionics equipment, which is electronic equipment installed inside the aircraft to support the performance of the relevant mission.

Avionics equipment is equipment that processes data received from various subsystems and supports users to successfully perform given missions through visualization.

Among avionics equipment, the separate memory module of the Data Transfer System (DTS) stores mission data planned on the ground (communication data, navigation data, weapons load information, etc.) in a portable storage device, and mission performance data from the aircraft during flight. It stores (aircraft status information, video/voice, etc.) to support mission performance.

The removable memory module is a data transfer unit (DTRU) that supports mission performance inside the aircraft and a removable memory module that stores mission performance data during flight (aircraft status information, video/audio, etc.). It consists of module).

The module assembly inside the avionics equipment used in an aircraft is mounted while maintaining bonding to the chassis structure using a wedge-shaped locking device to maintain the internal installation state and ensure heat conduction.

However, in high-acceleration and high-vibration environments such as aircraft, connectors included inside the aircraft had problems with being damaged or losing connectivity.

That is, at least one pin hole PH may be formed on the connector connection portion 121. The connector pin of the connector may be inserted into the pin hole (PH), and the pin hole (PH) and the connector pin may be in contact.

The board connector 122 may be inserted into the board connector of the memory board and electrically connected to it. Here, the board connector may refer to a surface-mounted connector connected to a memory device included in a memory board.

The film portion 123 may connect the connector connection portion 121 and the substrate connection portion 122 to each other. For example, the film portion 123 electrically connects the connector connection portion 121 and the substrate connection portion 122 and has flexibility, thereby minimizing stress generation due to vibration and acceleration of the aircraft. In addition, the flexible connector 120 of the present invention can prevent damage and deterioration of function of the connector.

As shown in FIG. 5, at least one guide line (FG) may be formed on both sides of the film portion 123. The guide line FG may refer to a portion in which at least a portion of the film portion 123 is cut.

Of course, depending on the embodiment, it may be implemented in various shapes (eg, zigzag shape, wave shape, etc.) in order to absorb more stress and guide deformation of the film portion 123.

For example, the guide line FG may be formed of a material with stronger elasticity than other areas of the film portion 123. Accordingly, the area where the guide line FG is formed can absorb most of the stress of the film portion 123 to prevent damage when the film portion 123 is stretched by acceleration of the aircraft.

However, the present invention is not limited to this, and of course, depending on the embodiment, the sealing film 1232 may be implemented with another material having elasticity.

The reinforcement film 1233 may be formed on at least a portion of the film portion 1232 to prevent damage to the wiring 1231 and the sealing film 1232 due to stress.

For example, the reinforcement film 1233 may be formed in an area where the sealing film 1232 covers the wiring 1231. Additionally, the reinforcement film 1233 may be formed on both sides of the sealing film 1232 where the guide line FG shown in FIG. 5 is formed. However, the present invention is not limited to this, and the reinforcement film 1233 can be formed in various areas where damage may occur due to stress (e.g., the connector connection portion 121, the area adjacent to the substrate connection portion 122, etc.). there is.
