A bent outlet high-voltage shielded electrical connector plug

Abstract

The invention discloses a bend-type outgoing line high-voltage shielding electric connector plug. The protection grade of an outer shell of a traditional large current bend-type outgoing line plug hardly reaches the standard. An outer shell of the plug of the invention comprises an outgoing line part and a plugging part. A switchover shield is sleeved and arranged in each switchover shield installation groove of the outgoing line part. A switchover sheath is sleeved and arranged in each switchover shield. A wiring terminal is sleeved and arranged in each switchover sheath. Each switchover shield is in contact with a shield outer sleeve through a spring on the inner wall of the switchover shield. A shield inner sleeve is sleeved and arranged in each shield outer sleeve. A plugging shield is fixedly sleeved and arranged in each plugging shield assembling hole of the plugging part. A plugging column is sleeved and arranged in each plugging shield. The head part of each plugging column extends into a corresponding plugging column positioning hole of the outer shell of the plug. Screw threads of each plugging column are connected with a screw thread hole of the corresponding wiring terminal, and a conical surface of each plugging column is connected with a conical hole of the corresponding wiring terminal. According to the invention, the small-size internal bend-type outgoing line can be realized and the short circuit between lead wires and cable shielding layers can be prevented.

Description

Technical field [0001] The invention belongs to the field of electrical systems, and relates to electrical connectors, in particular to a bent-out high-voltage shielded electrical connector plug. Background technique [0002] In modern industrial electrical systems, electrical connectors are used more and more widely, and the number is increasing. The demand for connector outlet methods is also increasing, and the demand for 90° curved outlet is the majority. [0003] The traditional elbow outlet electrical connector plug generally adds an elbow at the end of the plug to achieve the purpose of elbow outlet. The elbow is connected with the plug shell in a threaded or snap-fit ​​manner. The elbow outlet plug of this scheme is adopted. It is only suitable for low-current plugs, because large-current plugs need to use cables with a larger cross-sectional area, and cables with large cross-sectional areas also have a larger turning radius. The solution of adding an elbow at the end of th...

[0003] The traditional bent outlet electrical connector plug generally adds an elbow at the end of the plug to achieve the purpose of the bent outlet. Only suitable for plugs with small currents, because plugs with large currents need to use cables with larger cross-sectional areas, and cables with large cross-sectional areas have a larger turning radius. For the plug of the current curved outlet, generally a terminal is connected to the wire first, and then connected to the contact through the terminal to achieve the curved outlet. In this solution, the shell needs to be made into a component, that is, a part cannot be bent. However, after the shell is made into components, the protection level is difficult to meet the standard; it can be seen that the traditional bent outlet plug cannot meet the requirements of modern industrial electrical systems, especially the use requirements of new energy vehicles for the bent outlet electrical connection plug
