Technical field

The invention relates to the field of communication equipment, specifically a half-pack shielding shell structure and a connector.

Background technique

Connectors are a component that our electronic engineering technicians often come into contact with. Its function is to build a bridge of communication between blocked or isolated circuits in the circuit, so that current can flow and the circuit can achieve the predetermined function. It is an indispensable component of electronic equipment and flows along with the current. If you observe the circuit, you will always find that there are one or more connectors. The form and structure of the connector are ever-changing. Depending on the application object, frequency, power, application environment, etc., there are various forms of connectors.

The shielding shell is a metal shell used on the connector. Its main purpose is to protect the connector and provide shielding. When signals are transmitted, the connector will produce electromagnetic interference. Inadvertent electromagnetic waves affect the signal quality. The shielding shell can prevent this interference. and improve connector performance.

Existing connectors are basically produced using an assembly line production model. The shielding shell on the connector is designed to be large in order to wrap the wiring port of the connector. The shielding shell needs to be fixed to the connector with screws and other fasteners. On the terminals, the installation efficiency is poor and it is not suitable for mass production of connectors.
