Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to an electrical connector. Background Technology

[0002] In the field of communication technology, connectors are typically used to connect circuits, enabling communication between the overall circuitry. Existing connectors generally consist of a male connector and a female connector. The male connector has several pins, and the female connector has several holes that mate with the pins. After the pins and holes are connected, the male and female connectors are secured with screws. However, in existing technology, screw holes are provided on the male connector, and screws are used to mate and secure the male and female connectors. During frequent disassembly and assembly, the screws can cause wear on the threads inside the screw holes, leading to unstable connections, significantly reducing the lifespan of the male connector, and also affecting the stability of the circuit connection.

[0003] Sensors, drivers, heating elements, and measuring components installed inside a vacuum system typically require electronic devices to transmit electrical or control signals to the outside of the vacuum chamber. Because the gas pressure is extremely low in a vacuum environment, materials exhibit significant outgassing behavior. Furthermore, the electrical insulation properties and heat dissipation conditions differ significantly from those in an atmospheric environment. Therefore, ordinary atmospheric electrical connectors are insufficient to meet the requirements for long-term stable operation.

[0004] To achieve electrical connections between the inside and outside of a vacuum chamber, a metal-glass sealed electrical feedthrough is commonly used. Among these, the DB (D-type data interface connector) multi-pin interface, due to its numerous pins and compact layout, is suitable for simultaneously transmitting multiple signals and is therefore widely used in scientific research facilities, accelerator equipment, ultra-high vacuum experimental platforms, and semiconductor process cavities. However, in vacuum systems involving multiple signals, shielding and grounding are crucial for ensuring signal integrity. Typically, the number of grounding points within a vacuum chamber is limited. To avoid interference or the formation of unnecessary loops, the shielding layer of the conductors or the outer casing of the devices within the vacuum chamber must be reliably led to a unified grounding terminal, thereby reducing electromagnetic interference and contact noise.
