Embodiment

Embodiment one

As the be connected fastener of Fig. 1 to power grid line insulator shown in Figure 5 and lead, this connection fastener comprises housing 10 and is connected, the cassette tape 20 of rugged housing, housing 10 is made by compression strength height and flexible elastomeric material, the shape of its end face is the U font substantially, lead 30 and insulator 40 all are positioned at housing 10, the top of housing 10 has the inner arc surface wire casing suitable with the outer edge surface of lead 30, housing 10 is placed on the lead 30 by this inner arc surface wire casing, all extend an anchor ear 11 that is used for wrap insulate 40 on four trough rims of two ends of wire casing downwards, anchor ear and trough rim are one; This anchor ear 11 has and the suitable inner arc surface of the outer edge surface of insulator 40, anchor ear 11 is by this inner arc surface clip insulator 40, in the terminal correspondence of two anchor ears of every side line trough rim bayonet socket 12 and buckling parts 13 are set, this buckling parts 13 has through hole, and an elastic sheet metal 15 is installed in the through hole.

One end of cassette tape 20 is columniform head 22, the size of this head 22 is greater than the bore of bayonet socket 12, the other end of cassette tape 20 is an afterbody 23, this afterbody 23 has the toothrow 21 of one section ladder type, 15 one-tenth rightabouts of elastic sheet metal of this toothrow 21 and buckling parts 13, after the afterbody 23 of cassette tape 20 passes the bayonet socket 12 of anchor ear, the bayonet socket 12 of anchor ear blocks the head 22 of cassette tape 20, after the afterbody 23 of cassette tape 20 passes the through hole of bayonet socket 12 and buckling parts 13, toothrow 21 by its afterbody 23 be installed in buckling parts 13 through holes in sheet metal 15 between buckle mutually, to realize the self-locking of cassette tape 20, thereby fastening lead 30 and the insulator 40 that is installed in the housing 10, and realize lead 30 and insulator 40 fastening contact the between the two.
