Furthermore, referring to Fig. 7, shown in 8, in above-mentioned insulation puncture line clamping, wire guide is by puncture tip
Main cables 27 is turned on by 10 with the metallic conductor 24 in a cable 26, therefore puncture tip 10 is straight with the contact area of metallic conductor 24
Connect the current-carrying capacity affecting contact position, as puncture tip 10 uses traditional needle point formula structure, then puncture tip 10 and metallic conductor
24 is point cantact, is unfavorable for the current-carrying capacity ensureing puncture tip 10 with metallic conductor 24 contact position, can only be by increasing puncture tip
The quantity of end 10 overcomes, and on the one hand can increase the manufacture difficulty of insulation puncture line clamping, on the other hand then causes insulating barrier 23
Puncturing place more, sealing is more difficult to ensure that；For overcoming above-mentioned deficiency, the present invention also has a following improvement:
The most as shown in Figure 10, the top of puncture tip 10 is yi word pattern blade 31, and the blade tip of this yi word pattern blade 31 is in directly
Wire, and the centerline axis parallel of the straight line at blade tip place and cable trough 3；Thus one, puncture tip 10 and metallic conductor 24
Non-point cantact, but in linear contact lay, increase the contact area of puncture tip 10 and metallic conductor 24, improve the current-carrying of contact position
Amount.
