242 electrical connection, the one end of puncturing lever 242 far from insulation sleeve 25 is tapered, puncturing lever 242 close to 25 one end of insulation sleeve diameter with
The outer diameter of insulation sleeve 25 is identical.It is that puncturing lever 242 provides support force using insulation sleeve 25, it is anti-using the wearability of polytetrafluoroethylene (PTFE)
It is scratched when only the second stitch 24 pierces through the first conductive layer 13 and leads to short circuit, keep composite board use safer.Because wearing
Thorn stick 242 and insulation sleeve 25 sliding connect, to far from blank assemblies direction drawing LED lamp component 2 when, fixed plate 22 pulls absolutely
Edge set 25 is mobile to the direction far from blank assemblies, and the effect puncturing lever 242 in frictional force is static, so puncturing lever 242 with
Insulation sleeve 25 slides in the direction away from each other, and puncturing lever 242 is no longer contacted with conducting rod 241 to which the two no longer realization is electrically connected
It connects, and then LED lamp component 2 is made not shine.It can be arranged in board body 1 in advance using above-mentioned characteristic two or more different
Information pattern makes this group information pattern by the outside drawing of LED lamp component 2 for the group information pattern not used when needing to switch
2 no power of LED lamp component, thus it is more convenient change board body 1 on information pattern.
As shown in figure 3, puncturing lever 242 has been fixedly and coaxially connected connecting rod 243, connecting rod close to one end of insulation sleeve 25
243 are placed through in insulation sleeve 25 and the two is in sliding connection, when 242 one end of puncturing lever contacts at insulation sleeve 25, conducting rod 241
Contact at connecting rod 243.243 side wall of connecting rod has been fixedly and coaxially connected bulge loop 244, and 25 inner wall of insulation sleeve has been fixedly and coaxially connected
Ring edge 251.When bulge loop 244 contacts at the one end of ring edge 251 far from puncturing lever 242, conducting rod 241 and connecting rod
243 do not contact.When needing to pull up LED lamp component 2 from board body 1, using ring edge 251 contradict bulge loop 244 to
Pulling force far from board body 1 is applied to bulge loop 244, can be pulled out from board body 1 with puncturing lever 242, prevent puncturing lever 242
It is stranded in board body 1.
