Embodiment

As accompanying drawing 1 to shown in the accompanying drawing 3, the utility model mainly comprises a pedestal 1, a stator 2, a shell fragment 3 and a terminal 4, wherein, this pedestal 1 is the

grooving

11,12 that is respectively equipped with different in width in inner both sides, central authorities then establish with a trepanning 13, make these trepanning 13 extensions one be located at the fixing hole 14 of rear wall wall, and establish with end difference 141 in the inner edge of this fixing hole 14; This stator 2 is to establish the L shape that portion 22 constitutes by inserting part 21 and weldering, makes inserting part 21 be embedded at grooving 11, and establishes portion 22 in weldering and establish with cambered surface 221 and open-work 222, is beneficial to be welded in printing board PCB; Shell fragment 3 is to establish the L shape that portion 32 constitutes by the contact site 31 of continuous bending and weldering, makes contact site 31 be embedded at grooving 12, and establishes portion 32 in this weldering and establish equally with cambered surface 321 and open-work 322, for being welded in printing board PCB; Terminal 4 is to be cylindric, its terminal vertical extent one weld tabs 41, and be provided with the italic grab 42 of symmetry in the adjacent end place, the adjacent front end place then is provided with the outstanding contact chip 43 that is connected to terminal 4 bodies; Combination by aforementioned components, this pedestal 1 is after being embedded at grooving 11,12 with stator 2, shell fragment 3, terminal 4 is planted by fixing hole 13, the end difference 141 that makes its oblique shape grab 42 be fastened on fixing hole 14 forms fixing, and make terminal 4 be exposed to trepanning 13, after 13 insertions of attaching plug trepanning, be contacted with the contact chip 43 of shell fragment 3 and terminal 4 respectively, to reach electric action.
