Problems solved by technology

However, due to the difference in the positioning accuracy of the guide rails in the existing connectors of this type, the positioning accuracy of some modules cannot meet the requirements of use, so that the connectors cannot be completely positioned and aligned when they are mated, and there is a certain amount of deflection. For small configurations For high-density contact modules, this amount of deflection will cause the contacts to be pinned, unable to be mated or cause damage to the contacts.
At the same time, with the development of electromagnetic compatibility technology, more and more applications have proposed electromagnetic shielding requirements, not only requiring the connector to be electromagnetically shielded after mating, but also the separated plug or socket. Radiation-type electromagnetic interference achieves attenuation, but most of the existing cabinet-type electrical connectors can only be electromagnetically shielded after mating, and cannot be electromagnetically shielded after separation

Abstract

A cabinet-type electric connector consists of a plug and a socket; the plug and a shell of the socket are provided with a plurality of cavities for mounting a plurality of corresponding functional modules; and the abutting end of each functional module is provided with a mobile electromagnetic shielding device and a guide positioning device, wherein the mobile electromagnetic shielding device consists of a shielding plate, an elastic shielding reed, an insulating sleeve and a spring. By using a matching form of the mobile shielding plate and the elastic shielding reed, the electromagnetic shielding function after the connector is plugged and separated is well implemented; meanwhile, the arranged guide positioning device can well implement guiding and positioning when the plug is plugged in the socket so as to realize automatic alignment of the connector; and the cabinet-type electric connector has higher mounting error compensation capability, meets the requirements of cabinet-type application occasions, and has stronger practicability.

Description

technical field [0001] The invention relates to a cabinet-type electrical connector, which belongs to the technical field of electrical connectors. Background technique [0002] The cabinet-type electrical connector is used between the case and the cabinet. Each cabinet unit is a functional module, which is positioned by the guide rail and loaded into the case to form an electrical control system. Existing cabinet-type electrical connectors are generally equipped with guides for preventing misinsertion, and adopt a modular structure, and each connector is composed of multiple modules. However, due to the difference in the positioning accuracy of the guide rails in the existing connectors of this type, the positioning accuracy of some modules cannot meet the requirements of use, so that the connectors cannot be completely positioned and aligned when they are mated, and there is a certain amount of deflection. For small configurations For a high-density contact module, this a...
