Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Examples

As shown in fig. 1, 2 and 3, an interchangeable plug structure comprises an interchangeable plug socket 1, a lower shell 2, a metal contact pin 3, a spring 4, a metal elastic sheet 5 and a spring gland 6, wherein the power system 7 is powered, after the assembly, the metal contact pin of the interchangeable plug socket 1 is in contact with the metal contact pin 3, then the metal contact pin 3 is in contact with the spring 4, the spring 4 is in contact with the metal elastic sheet 5, and the metal elastic sheet 5 is used for connecting the power system 7 for power supply, and as shown in the following figures, the whole process forms a conductive circuit system.

After the head-replaceable pin holder 1 and the lower shell 2 are assembled, the metal contact pins 3 and the springs 4 are combined to form a compression magnitude, so that the springs are compressed when the head-replaceable pin holder 1 is assembled, the metal contact pins 3 are in closer contact with the metal pins of the head-replaceable pin holder 1, and a conductive circuit system is more stable.

As shown in fig. 4, the L-shaped protrusion 11 of the socket 1 with replaceable head is pushed into the L-shaped concave chute 12 of the lower housing 2, and the L-shaped structure is adopted for mutual matching, locking and limiting, so that the matching is tighter; the metal contact pin 3 moves in the sliding groove of the socket 1 with the replaceable head, so that the metal contact pin can be in good contact with the metal pin of the socket 1 with the replaceable head, and poor contact caused by deviation is avoided.

As shown in fig. 4, the lower housing 2 is locked by the wedge portion 8 in cooperation with the socket 1 with the replaceable head, and the locking edge of the socket 1 with the replaceable head is pushed into the locking groove 9 of the lower housing 2 to be locked, so that the assembly is firmer and more reliable. When the replacement button 10 is pressed down lightly, the socket 1 with the replaceable head can be taken out easily.

During the assembly, earlier constitute a subassembly with lower casing 2, metal contact pin 3, spring 4, metal spring plate 5 and spring gland 6, then assemble interchangeable head pin holder 1 and preceding subassembly, slowly push the locking position with the hand and accomplish the assembly promptly, when will dismantling, directly press change button 10 with the hand, can easily take out interchangeable head pin holder 1.

Fig. 5 is a schematic diagram illustrating the assembly of the pin holder for the U.S. standard, the European standard and the English standard, and the pin holder for the safety standard in other countries is the same.

The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
