DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-5 A hard disk signal connection cable comprises a first connection terminal 1, a second connection terminal 2 and a cable body 3, one end of the cable body 3 is connected to the first connection terminal 1, the other end of the cable body 3 is connected to the second connection terminal 2, a first docking shell 16 is arranged on the first connection terminal 1, a first gold finger 15 is arranged in the first docking shell 16, a second docking shell 17 is arranged on the second connection terminal 2, a second gold finger 18 is arranged in the second docking shell 17, two mutually symmetrical docking strips 6 are arranged on the first connection terminal 1, two mutually symmetrical docking holes 5 matched with the docking strips 6 are arranged on the second connection terminal 2, a locking plug 8 is slidably arranged in the docking hole 5, and a locking hole 7 matched with the locking plug 8 is opened on the docking strip 6.

[0022] By means of the mutual cooperation of the structures such as the docking strip 6, the docking hole 5 and the locking plug 8, when the first connection terminal 1 is docked with the second connection terminal 2, the docking strip 6 on the first connection terminal 1 is inserted into the docking hole 5 on the second connection terminal 2, and at the same time, the locking plug 8 in the second connection terminal 2 is inserted into the docking strip 6, so that the docking strip 6 is locked in the docking hole 5, thereby achieving the purpose of locking and fixing the first connection terminal 1 and the second connection terminal 2.

[0023] Specifically, in this embodiment, a transmission cavity 9 is opened on the second butting terminal, a sliding block 13 is slidably arranged in the transmission cavity 9 , and two locking plug blocks 8 are welded to the sliding block 13 .

[0024] By cooperating with the sliding block 13 and the locking plug block 8 , the sliding block 13 can slide in the transmission cavity 9 to drive the locking plug block 8 to slide.
