Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the connecting structure comprises a shell 10, a tail 11, a threaded sleeve 20, a collar 21, a connecting rod 22, a wedge 23, a main connecting part 12, a first connector 13, a second connector 50, a connecting plate 5, a clamping groove 52 and an auxiliary connecting part 51.

The first embodiment is basically as follows:

a computer interface device comprises a plug and an interface slot, as shown in figure 1, the plug comprises a shell 10, a tail part 11 is arranged in the shell 10, the lower end of the tail part 11 is fixedly connected with the inner wall of the shell 10, and a groove is formed between the circumferential side wall of the tail part 11 and the shell 10. The data line is connected with a first interface 13 through the tail 11. The circumferential side wall of the tail part 11 is in threaded connection with a threaded sleeve 20, a sleeve ring 21 is arranged in the groove, and the lower end of the threaded sleeve 20 is abutted against the sleeve ring 21. The lower surface of the lantern ring 21 is fixed with a connecting rod 22, the connecting rod 22 penetrates through the bottom of the groove and is vertically connected with the bottom of the groove in a sliding mode, and the connecting rod 22 is also vertically connected with the inner wall of the shell in a sliding mode in the shell 10.

A main connection portion 12 is fixed to a lower end surface of the housing 10, and as shown in fig. 2, a cavity communicating with an inner space of the housing 10 is formed in the main connection portion 12. The lower end of the connecting rod 22 extends into the cavity of the main connecting part 12 and is provided with an inclined surface, the inclined surface is matched with a wedge 23, a transverse opening is arranged between the cavity and the side surface of the main connecting part 12, and the wedge 23 is in sliding connection with the opening. The wedge block 23 is sleeved with a spring, one end of the spring is abutted to the inner wall of the opening, and the other end of the spring is abutted to a protrusion arranged on the sliding block.

As shown in fig. 1, the interface slot includes a connection board 5, the connection board 5 is fixed to the computer body, and a second interface 50 is provided on the connection board 5 and is used for forming an electrical signal connection with the first interface 13. Two sides of the second connector 50 are provided with secondary connecting parts 51 (see fig. 2), and opposite inner sides of the two secondary connecting parts 51 are provided with clamping grooves 52 which can be matched with the wedge blocks 23.

After the second connector 50 is inserted into the first connector 13, the main connecting portion 12 is adjacent to the secondary connecting side. The threaded sleeve 20 is manually rotated, so that the threaded sleeve 20 moves downwards relative to the tail 11 through threads, the collar 21 and the connecting rod 22 are pushed to slide downwards, the lower end of the connecting rod 22 pushes the wedge 23 to transversely slide out of the opening through the inclined surface, and the spring is extruded during the process that the wedge 23 slides out of the opening. The wedge block 23 slides out and partially enters the clamping groove 52 to be matched, so that the locking of the plug and the interface groove is realized.
