MCU (micro control unit) bus socket with shielding function

Abstract

The invention discloses an MCU (micro control unit) bus socket with a shielding function. The MCU bus socket comprises a pin mounting plate, a shielding cover and a plastic socket shell. The shielding cover is positioned between the socket shell and the pin mounting plate and covers the pin mounting plate. The socket shell, the shielding cover and the pin mounting plate are in mutual fastening connection. Contact-preventing walls, pin components and a sheath are arranged in the pin mounting plate. A signal hole for signal communication is formed in the sheath. Compared with existing sockets, the MCU bus socket has the advantages that a metal shell serving as a mounting and support piece is not needed, and thus, the size of the socket can be decreased; part types for the socket can be reduced; good shielding communication between the shielding cover and a mounting faceplate and high shielding effectiveness of the socket can be guaranteed; the MCU bus socket has a contact-preventing function, and production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to a shielded MCU bus socket. Background technique [0002] Traditional bus sockets, especially shielded MCU bus 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. Ensure a safe distance and a sufficiently thick insulating medium, so that the socket can work normally under high-voltage conditions; this method of processing to achieve high-voltage functions often makes the insulating mounting plate larger in size, which is not suitable for connecting In the occasions where the size of the...

[0002] Traditional bus sockets, especially shielded MCU bus 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. Ensure a safe distance and a sufficiently thick insulating medium, so that the socket can work normally under high-voltage conditions; this method of processing to achieve high-voltage functions often makes the insulating mounting plate larger in size, which is not suitable for connecting In the occasions where the size of the device 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 The conduction between the gold tail shell and the mounting panel can only be realized by mounting screws; in order to achieve shielding, the metal shell must be used as the shielding function, and the metal shell is usually a machined part and conducts electricity. After the surface is used, the processing cost of the parts is high, the efficiency is low, and the weight of the connector is also heavy; and the metal shell and the mounting panel can only be connected through the mounting screw, and when installing, it is usually necessary to coat the thread on the mounting screw Glue, and 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 performance is unstable, and the overall quality is heavy , high production cost and low production efficiency, especially not suitable for the use requirements of new energy vehicles for electrical connectors with small size, good shielding efficiency, high production efficiency and low production cost
