Bend type shielded mcu bus plug

Abstract

The invention discloses a bending type shielded MCU (Micro Control Unit) bus plug and relates to the field of electrical connectors in the field of new energy vehicles, industrial equipment and urban rails and railway vehicle electrical appliances. The bending type shielded MCU bus plug consists of a lower shielding cover, a jack mounting plate, an upper shielding cover, a jack component, a sealing ring, a plug housing, a locking block, a handle, a left shielding cover, a protective sleeve, a right shielding cover, a self-locking nut, a connecting terminal, a shielding cushion cover, a shielding pressure sleeve, a wire sealing body and a tail cover. With the adoption of threaded switchover, bending type wire outgoing is realized; in an assembly state, the two ends of the jack component are respectively fixed in a jack mounting hole and a jack positioning hole of the plug shell; the connecting terminal is rigidly connected with the jack component through connecting threads, so that when a cable is subjected to axial stress, the jack component cannot incline at an inserting position. The bending type shielded MCU bus plug has the advantages of being small in size, good in shielding effectiveness, low in production cost, high in production efficiency, easy to operate, reliable in contact part contact and the like.

Description

technical field [0001] The invention relates to electrical connectors in the electrical fields of new energy vehicles, industrial equipment, urban rail and railway vehicles, in particular to curved shielded MCU bus plugs used in new energy vehicles. Background technique [0002] In modern industrial electrical systems, the use of electrical connectors is becoming wider and wider, and the number is increasing. There are also more and more requirements for the outlet methods of the connectors, and the demand for 90-degree bent outlets is the majority. [0003] The traditional curved outlet electrical connector plug generally adds an elbow at the end of the plug to achieve the purpose of the curved outlet. The elbow and the plug shell are connected by threads or buckles. , only suitable for small current plugs, because high current plugs need to use cables with larger cross-sectional areas, and cables with large cross-sectional areas have a larger turning radius, and the soluti...

[0003] The traditional curved outlet electrical connector plug generally adds an elbow at the end of the plug to achieve the purpose of the curved outlet. The elbow and the plug shell are connected by threads or buckles. , only suitable for small current plugs, because high current plugs need to use cables with larger cross-sectional areas, and cables with large cross-sectional areas have a larger turning radius, and the solution of adding a bend at the end of the plug cannot meet the requirements; the traditional For a plug with a large current curved outlet, generally a terminal and a wire connector are used first, and then the terminal is connected to the contact to achieve a curved outlet. Type outlet, but after the shell is made into a component, the protection level is difficult to meet the standard; the traditional angled connector plug with shielding function usually uses a pair of separate contacts to realize the conduction between the shields. This method of shielding treatment The shielding effect of the method is not good, and because of the extra shielded conductive contact pairs, the size of the connector is increased. It can be seen that the traditional bent outlet plug with shielding function cannot meet the requirements of modern industrial electrical systems, especially Requirements for the use of curved shielded plugs for new energy vehicles
