Fig. 2 is that electric connector of the present invention is assemblied in the schematic diagram on the circuit board.
Fig. 3 is that the stereogram of another angle of electric connector of the present invention is to illustrate the lip-deep structure that electric connector combines with circuit board.
Embodiment
Please refer to Fig. 1～Fig. 3, the invention provides a kind of electric connector, the shield shell 3 that comprises plastic cement core body 1, is located at the terminal 2 on the plastic cement core body 1 and is fixed in plastic cement core body 1 outside.
Described plastic cement core body 1 mainly provides the carrier of terminal 2, and correspondingly plastic cement core body 1 is provided with plurality of terminals groove (scheming not shown).And terminal 2 promptly is embedded in the described terminal groove.
Described shield shell 3 is wrapped in the metal shell of the outside of plastic cement core body 1, normally is fixed on the plastic cement core body 1 by the buckle mode.On shield shell 3, also protrude and be formed with salient point 30 and shell fragment 32, thereby described salient point 30 and shell fragment 32 elasticity press on this supporting electric connector and can play good positioning action when this electric connector and supporting electric connector are pegged graft, make that the combination of electric connector is more firm, be difficult for becoming flexible, it is better to connect conduction property.When specific design, can be provided with several described salient points 30 respectively symmetrically at described shield shell 3 two relative narrow avris; And be provided with several described shell fragments 32 respectively symmetrically in described shield shell 3 two relative broadside sides.By being symmetrical arranged salient point 30 and shell fragment 32, can guarantee stress equalization when pegging graft with supporting electric connector, stability is better.
Described shell fragment 32 comprises lead-in chamfered 320, pressure section 322 and the fixed part 324 that the inserted terminal from electric connector connects successively to the line extreme direction, described lead-in chamfered 320 tilts towards the inserted terminal direction, and pressure section 322 then protrudes so that can press on the supporting electric connector of being pegged graft towards supporting electric connector direction.Preferably, described shell fragment 32 can be designed to arch-shapedly, the lead-in chamfered 320 at shell fragment 32 two ends and fixed part 324 all link into an integrated entity with shield shell 3.
