The invention relates to a multipurpose combined spring wire which comprises a first combined wire, a second combined wire, a transition sleeve and a tail end sleeve. The first combined wire comprises a first spiral cable and a first spiral spring wire body, and the first spiral spring wire body is sleeved with the first spiral cable; the second combined wire comprises a second spiral cable and a second spiral spring wire body, and the second spiral spring wire body is sleeved with the second spiral cable; the transition sleeve is a cylindrical rubber sleeve, and a first cable channel, a first spring channel, a second cable channel and a second spring channel are longitudinally formed in the transition sleeve. The multipurpose combined spring wire can overcome the telescopic spring back defect in the prior art, the condition that spring-back is not in place due to fatigue and repeated use can be avoided, and potential safety hazards caused by forced stretching of the spring wire are further avoided.
Description
technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a multipurpose combined spring wire. Background technique [0002] At present, after a long period of use, the helical spring wire is prone to fatigue and cannot return to the original length level, resulting in the inability to rebound in place, which will eventually lead to telescopic failure. The wire body is forced to stretch under the failure state, which will cause The damage of the inner conductor will pierce the insulation jacket and connect with the wall of the aluminum gold extension tube, which will pose a risk of electric shock to personnel. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-purpose combined spring wire for the above disadvantages, which can overcome the defects of telescopic springback in the prior art, and can avoid the situation of fatigue and insufficient springback cau...
