Specific embodiment
With reference to embodiment and accompanying drawing, detailed description further, but embodiments of the present invention are made to the present invention
Not limited to this.
Embodiment 1：
As shown in figure 1, the electric interfaces component of long service life, including plug and socket, the plug includes jack shell
Body 1, the plug insulator 3 being arranged in plug casing 1 and some contact pins 5 being embedded on plug insulator 3；The socket bag
Socket casing 2, the socket insulator 4 being arranged in Socket casing 2 are included, multiple jacks 6 are preset with the socket insulator 4.
When using, in the insertion jack 6 of contact pin 5, it is connected with the wire in socket and realizes electrically conducting, conversely, extract contact pin 5 realizes electrically
Disconnect, the structure and connected mode of the wire in contact pin 5 and jack 6 and socket just seem identical with existing, non-invention
Protection point, here is omitted its structure and principle.Inventive point of the invention is the shell structure of plug and socket.
As shown in 1 and Fig. 2, the plug casing 1 is connected including the first wire interconnecting piece 11 with the first wire interconnecting piece 11
Socket connection part 12, plug insulator 3 and contact pin 5 are installed in the connecting wire of first wire interconnecting piece 11, socket connection part 12,
Contact pin 5 is connected with the wire in the first wire interconnecting piece 11.
As shown in figures 1 and 3, the Socket casing 2 include the second wire interconnecting piece 21 and with the second wire interconnecting piece 21
Installed in the plug connection 22 of connected hollow cylindrical, the connecting wire of the second wire interconnecting piece 21, plug connection 22 and inserted
