Description

Shielding cover structure of connector for vehicle Technical Field The utility model belongs to the technical field of automobile connectors, and particularly relates to a shielding cover structure of an automobile connector. Background With the continuous increase of the degree of automotive electronics, the importance of connectors in automotive electrical systems is increasingly highlighted. Connectors are an indispensable component in electronic devices, whose main function is to ensure reliable connection between circuits, transmitting electric current or signals. In an automotive connector, a shielding case is generally provided, and the shielding case has a main function of preventing electromagnetic interference, ensuring stability and reliability of signal transmission, protecting internal components of the connector from damage of external environment, prolonging service life of the connector and improving performance of the connector. In the prior art, in the process of installation and use of a connector shielding cover for a vehicle, the problems that an insulating inner shell is not firmly connected with a shielding cover shell, an external plug is difficult to insert and the like often exist, so that signal transmission is unstable or the connector is damaged. For this purpose we propose a connector shield case structure for vehicles. Disclosure of utility model The utility model aims to provide a shielding cover structure of a connector for a vehicle, which can effectively ensure reliable connection between an insulating inner shell and a shielding cover shell, provide effective guide for inserting an external plug and improve the service performance of a product. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a shielding cover structure of a connector for a vehicle, which comprises an insulating inner shell, wherein a shielding cover shell is arranged outside the insulating inner shell, a connecting bent plate which is bent upwards is arranged at the periphery of the bottom end of the shielding cover shell, a connecting lantern ring is sleeved outside the bottom of the shielding cover shell and clamped into a gap between the connecting bent plate and the shielding cover shell, a connecting buckle plate connected with the connecting lantern ring is fixed at the bottom end of the insulating inner shell, a plug bush is fixed at the upper end of the insulating inner shell, a mounting hole for the plug bush to pass through is formed in the shielding cover shell, a hollow pipe cavity is formed in the plug bush, an outwards-expanded guide port is formed at the upper end of the plug bush, and the outer side of the guide port is tightly attached to the edge of the mounting hole.
