[0041] Example 2

[0042] A method for using a cable quick connector comprises the following steps:

[0043] Step 1, put the second connector 26 into the connecting groove 232 of the first connector 23;

[0044] Step 2, rotating the second connector 26, the second connector 26 can further penetrate into the connecting groove 232, and the protrusion on the buckle 245 buckles into the second groove 261;

[0045] Step 3, the inner surface of the conductive slot 262 is exposed, and at the same time, the conductive component 223 of the conductive rod 22 is also exposed from the connecting piece 24 and penetrates into the conductive slot 262 to connect and conduct with the conductive slot 262;

[0046] Step 4, tighten the nut 265 with the outer thread.

[0047] Working principle:

[0048] Put the second connector 26 into the connecting groove 232 of the first connector 23, and the second connector 26 squeezes the buckle 245 to deform it in the direction close to the inner surface of the connecting groove 232. Since the second connector 26 abuts against the B side of the conductive rod 22, the protrusion on the buckle 245 cannot continue to approach the second groove 261. Then rotate the second connector 26. When the center line of the conductive rod 22 is in line with the center line of the stop rod 263, the second connector 26 can further penetrate into the connecting groove 232. The second connector 26 abuts against the connecting member 24, and the protrusion on the buckle 245 is buckled into the second groove 261. The conductive rod 22 squeezes the stop rod 263 to make it penetrate into the conductive groove 262. The spring 264 is squeezed and contracted, and the conductive groove 262 The inner surface is exposed, the second connector 26 continues to go deeper, and the connector 24 approaches the end side of the connecting groove 232. At this time, the deformation zone 252 of the deformation sleeve 25 becomes shorter, and at the same time, the conductive component 223 of the conductive rod 22 will also be exposed from the connector 24 and go deep into the conductive groove 262 to connect and conduct with the conductive groove 262. During the entire connection process, the conductive component 223 of the conductive rod 22 has not been exposed to the external environment. At the same time, the inner surface of the conductive groove 262 has not been exposed to the external environment, which can avoid being contaminated by impurities. There is no need to specially clean its surface, simplifying the connection steps, and realizing quick connection of the cable. Finally, the nut 265 is tightened with the external thread to fix the second connector 26 to the first connector 23.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents, and any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention should be covered within the scope of protection of the claims of the present invention.
