the utility model provides a bayonet socket size self-adaptation external power supply line for high-power electronic components provides external power supply, the power cord includes plug, live wire, zero line, ground wire and bayonet ring, the one end of live wire, zero line, ground wire is connecting plug respectively, a bayonet ring is connected respectively to the other end of live wire, zero line, ground wire, and bayonet ring meets with electronic components port, for electronic components power supply.
The bayonet ring comprises two semicircular rings, and is divided into an upper ring and a lower ring, the left end of the lower ring is provided with a groove, a plurality of pin columns are arranged in the groove, the right end of the lower ring and the left end of the upper ring are movably connected through a pin shaft, the left end of the upper ring is provided with a first boss, a plurality of pin column holes corresponding to the pin columns are formed in the first boss, the first boss and the groove are correspondingly matched in size and position, and the upper ring and the lower ring form a complete circular ring.
The right end of the lower ring is provided with a second boss, the right end of the upper ring is provided with a third boss, the two bosses are crossed, the pin shaft penetrates through the two bosses, and one side of the circular ring wall of each boss is provided with an arc surface inwards respectively for the upper ring to move up and down.
In order to prevent electric shock caused by mistaken touch, the bayonet ring is coated by insulating materials at the outer part and the connection part with the power line.
Firstly, in order to prevent electric shock and solve the electric leakage phenomenon, a layer of plastic insulating skin is covered outside a metal conductive copper wire stripped from a plug; then connecting the metal copper wire with a metal conductive snap ring; when in wiring, the bayonet is directly clamped to the external power supply port corresponding to the PLC. Secondly, in order to adapt to different application occasions, the bayonet ring is designed into a structure with the size of the bayonet capable of being adjusted in the bayonet ring design, so that the size of the bayonet is changed, and the aims of adapting to different types of PLCs and different components are fulfilled.
The utility model has the advantages that the PLC can be conveniently provided with an external power supply without needing to master much electrical knowledge to modify the PLC; meanwhile, the size of the bayonet can be adjusted to adapt to different types of PLCs and different types of components.
Drawings
The present invention will be further explained with reference to the accompanying drawings.
Fig. 1 is an overall structure diagram of the present invention.
Fig. 2 is a structural view of an adjustable bayonet of a power cord.
Fig. 3 is a top view of fig. 2.
In the figure, 1, a live wire, 2, a bayonet ring, 3, a zero wire, 4, a ground wire and 5 plugs are arranged.
Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
