High voltage belt shielding power socket

Abstract

The invention discloses a high voltage belt shielding power socket. The high voltage belt shielding power socket comprises contact pin fixing covers, shielding cases, contact pin assemblies and a socket shell, wherein a flange plate is arranged at one end of the socket shell; installation via holes are formed in the flange plate; the two opposite sides of the socket shell are each provided with a hollow cylindrical rotary shaft; two shielding installation cylinders are arranged in the socket shell; hexagonal rotation stopping contact pin installation holes are formed in the bottom of the plugging portions of the shielding installation cylinders, the bottoms of the hexagonal rotation stopping contact pin installation holes are connected with cylindrical contact pin positioning devices, and hanging tables are arranged on the outer walls of the cylindrical contact pin positioning devices. The parts complex in structure are formed by a mould, and compared with a traditional socket, the high voltage belt shielding power socket has the advantages of being small in size, good in shielding performance, low in production cost, high in production efficiency, and the like.

Description

technical field [0001] The invention belongs to the technical field of electrical connectors, and relates to a high-voltage shielded power socket, which is suitable for electric connectors used in industries such as new energy vehicles, industrial equipment, and urban rails, and is particularly suitable for high-voltage shielded power sockets for new energy vehicles. Background technique [0002] Traditional power sockets, especially high-voltage shielded power sockets, are usually composed of metal shell components, plastic mounting plates, collars, contacts, seals, tail accessories and other components. Except for plastic mounting plates, all parts are mechanical. Add parts; in order to achieve normal operation under high voltage conditions, the traditional socket needs special treatment for the structure of the plastic mounting plate to achieve a large electrical gap and creepage distance.

Problems solved by technology

[0002] Traditional power sockets, especially high-voltage shielded power sockets, are usually composed of metal shell components, plastic mounting plates, collars, contacts, seals, tail accessories and other components. Except for plastic mounting plates, all parts are mechanical. Add parts; in order to achieve normal operation under high voltage conditions, the traditional socket needs special treatment for the structure of the plastic mounting plate to achieve a large electrical gap and creepage distance. At the same time, it is necessary to ensure the contact between the contact and the metal shell A safe distance and a sufficiently thick insulating medium are required so that the socket can work normally under high-voltage conditions; this method of processing to achieve high-voltage functions often designs the insulating mounting plate to be larger in size, which is not suitable for connectors In occasions where the volume requirement is small; in order to realize the shielding function, the metal shell of the traditional socket must be connected to the installation panel, and the traditional socket is usually provided with a seal between the metal shell and the installation panel in order to realize the protection function, so that the socket's The conduction between the gold tail shell and the mounting panel can only be achieved through mounting screws; this method of shielding must use a metal shell as a shielding function, and the metal shell is usually a machined part, and the processing cost of the part is high , the efficiency is low, and the weight of the connector is also heavy; and the metal shell and the installation panel can only be connected through the installation screw, and when installing, it is usually necessary to apply thread glue on the installation screw, and the thread glue is non-conductive , so there is a hidden danger that the conduction of the shielding may be blocked or blocked; it can be seen that the traditional power socket is not suitable for occasions with small volume requirements, and the shielding effectiveness is unstable, the overall quality is heavy, the production cost is high, and the production efficiency is low. Low, especially not suitable for the use requirements of new energy vehicles for small size, good shielding performance, high production efficiency and low production cost of electrical connectors
