Description
Technical field
The utility model relates to a kind of electric connector, is meant the firm electric connector of a kind of metal shell structure especially.
Background technology
Electric connector is understood the clad metal housing usually with shield electromagnetic interference, and defines the insertion slot that docks for butt connector jointly by metal shell and insulating body.Therefore, if the structure of metal shell is firm inadequately,, causes metal shell to be strutted easily and damage at improper active force and the torsion that butt connector plug process produces.In addition, the structure of metal shell also can influence the volume of electric connector integral body, pursues under the compact trend at electronic product, and the volume of electric connector also need dwindle as much as possible, to avoid taking unnecessary space.
Existing electric connector for example, is consulted Fig. 1, ZL200620002331.X number (corresponding TaiWan, China patent TWM293552 of China Patent No.; Corresponding U.S. Pat 07371116) discloses a kind of socket-type electric connector 9, can plant respectively for the pin connector that meets the pin connector of eSATA signal transmission specification and meet the usb signal transmission specification.The metal shell 91 of electric connector 9 is to be shaped by the bending of metal sheet one, and utilizes the joggle structure of the concavo-convex cooperation of dovetail, at the planed joint 912 of diapire 911 in conjunction with the formation dock.Because seam 912 just is docking together, improper insertion force and torsion when being inserted by butt connector easily strut, though some can stamp impression at seam 912 places, make the local material small deformation at seam 912 places by impression, come the bond strength at reinforced seam 912 places, but still be not enough to bear the improper insertion torsion or the more strict insertion test of butt connector.In addition, as shown in Figure 2, electric connector 9 is provided with backplate 921 in the bottom of insulating body 92, and in the following backplate 921 inner jacks 922 that form, jack 922 matches with the inserted sheet 913 that directly extend backwards at metal shell 91 seams 912 places, can produce card after the assembling and end strength, and following backplate 921 support seams 912 places, avoid causing metal shell 91 to be ripped at seam 912 places because of processing flaw or improper use.Yet, because of following backplate 921 be a plastic material, still dislike not enough, and backplate 921 can increase the height of electric connectors 9 down for the bracing force of metal shell 91, also can't satisfy the demand of minimizing volume.
Other existing electric connector, for example the TaiWan, China patent announcement discloses a kind of connector assembly structure number No. 430160, include an insulating base frame and a metal covers shell, wherein insulating base frame bottom forward elongation moulding supporting bracket is arranged, the Extendible flake that face extension bending forming has the tool cramp is covered in the bottom side of covering shell, cover in the left side on the default button hole of face and can resist the outer support power of side direction and can overlap and detain knot, simultaneously supporting bracket is also with bracketing support power below face is covered in the bottom side and outside bearing downwards, can be by simple punching out processing and snapping and combination forming goes out the stronger structure that is enough to bear the Plug Action of butt connector and does not strut of structure so cover shell.But at the structure of the overlapping snapping of side,, increase a thickness of slab at least behind the metallic plate bending forming because overlapping part can increase the width of connector.And the disclosed cramp of embodiment is to snap onto from outside to inside in the button hole, and cramp can not be given prominence to button hole, otherwise can stretch in the grafting space of butt connector and interfere with the insertion of butt connector, makes that the snapping intensity of this kind snapping structure can be limited.
TaiWan, China patent announcement number No. 565042 (corresponding Chinese patent CN02157589.4 for example again; Corresponding U.S. Pat 06764339) a kind of shield type electric connector that discloses, its screening can is the two-piece type assembled configuration by last shell and lower casing assembling, can constitute overlapping side plate in both sides, at least increase by two thicknesss of slab, and upper and lower shell need separately be made and assemble structure very complicated and increase manufacturing process and cost.
Other is the housing of the connector of TaiWan, China patent announcement number M340642 number (corresponding PCT patent publication No. WO2008/140009A1) exposure for example, constitute by a slice metallic plate, be provided with the latching portion and the structure that is hooked in the hook portion in hole in hole in the place ahead of housing, the snapping structure at this place also makes the plate body of housing overlapping, its same metal shell can increase the width of connector in overlapping part, increases a thickness of slab at least.And when assembling, also to increase a fixedly bending snapping operation of wrist, structure is comparatively complicated, moreover its snapping structure protrusion housing is outer and form many sharp-pointed places, and is quite not attractive in appearance.
Summary of the invention
Therefore, the purpose of this utility model promptly is to provide a kind of electric connector that has the metal shell of firm fastening structure and can not increase additional volumes.
So the utility model electric connector comprises an insulating body, many butts and a metal shell.This insulating body has the hyoplastron that a base portion, is extended by this base portion forward, and connects these base portion two ends and lay respectively at two side arms of these hyoplastron both sides.Described a plurality of terminal is located at this hyoplastron respectively.This metal shell is sheathed on this insulating body, be shaped by the bending of metal sheet one, and have a relative roof and a diapire, and a relative the first side wall and one second sidewall, four define a rectangle frame mouth jointly, this the first side wall is by an inner wall part and an outside wall portions is overlapping and be made of at least one group first snap close piece and the mutual snap close of second snap close piece, and this first snap close piece is located at this inner wall part and this second snap close piece is located at this outside wall portions.This side arm of the first side wall of adjacent this metal shell of this insulating body wherein also is concaved with a depressed part of ccontaining this inner wall part.
Useful technique effect of the present utility model is, this metal shell is fixed by first snap close piece and the mutual snap close of second snap close piece, has preferable retain strength, can resist the improper insertion force and the torsion of butt connector, can do not strutted, and the side arm of this insulating body is formed with the inner wall part of depressed part with ccontaining this metal shell, can not increase the width of this electric connector integral body, meets the demand of volume miniaturization.
