Technical Field

The utility model relates to a connector, in particular to a quick-disassembly locking head for a connector, a male connector and a connector.

Background

The screw locking circular connector is widely applied to medical equipment, outdoor illumination, outdoor audio and video, industrial sensors, industrial vision cameras, controllers, profibus, profinet, deviceNet, CANBUS, IOLINK, CCLINK, interbus, ethernet/IP, etherCAT and other field buses and IEC50155 industrial switches, and has become a universal electrical standard connector worldwide, and the international electrotechnical commission defines the standard of the connection interface of the circular connector by the standards of IEC 61076-2-101 (M12 connector), IEC 61076-2-104 (M8 connector), IEC 61076-2-105 (M5 connector) and the like, thereby promoting the use of the screw locking circular connector in more industries such as rail transit, industrial robots, wind power generation, semiconductor devices, machine tools, petrochemical industry, security monitoring and the like.

Screw locking round connectors are typically made up of male and female connectors that are screwed together. The male and female module generally comprises a shielding cable, a rubber coating shell, a shielding lantern ring, a contact pin/jack, a locking nut and a plastic insert. These materials are assembled to form a male or female connector.

The existing male and female connectors have the following defects through screw locking: the electric connection of the male/female connector is realized through the connection of the corresponding contact pin/jack in the plastic rubber body, the action principle is that the lock nut pushes the contact pin/jack in the plastic plug body to connect through the spiral rotation of the screw thread, the screwing length of the screw thread is longer, the screw screwing has specific moment requirement, and the operation of a moment wrench is time-consuming; and because of the high-density wiring application of modern industry, the industrial field space is narrow and small, and the torque wrench is inconvenient to use for operation. Particularly in industrial 4.0 application, when a large number of screws are required to be inserted into/pulled out from a circular connector for locking during installation, debugging, overhauling and maintenance of the connector, a controller, a field bus and the like, huge workload of rotating the locking screws is brought, overlong downtime of equipment is caused, and great economic loss is caused.

In order to solve the problem of the inserting/extracting speed of the screw locking circular connector, manufacturers such as industry leading manufacturers Harting and Phoenix jointly push out the IEC 61076-2-010 standard, industry huge head TE cooperates with Yamaichi to push out the IEC 61076-2-012 standard, and the screw locking structure is updated through a grooving and clamping buckle adding mode on the basis of the existing screw locking circular connector, so that the quick inserting/extracting connection compatible with the existing screw locking is realized. The IEC 61076-2-010 and IEC 61076-2-012 standard materials both modify the structure of the existing screw locking circular connector, increase the material processing cost, cause the material cost to be too high, and the existing screw locking circular connector with massive non-updated structure cannot realize the function of quick insertion/extraction.
