See also shown in Fig. 1-3, metal shell 4 comprises with the parallel relative shell roof 40 of the external circuit board 2, the shell butt joint wall 41 that extends from shell roof 40 front sides downwards, extends downwards and dock the relative shell rear wall 42 of wall 41 with shell and from the shell roof 40 and arranged on left and right sides bending shell side wall 43 of extension downwards from shell roof 40 rear sides.Shell butt joint wall 41, shell rear wall 42 and shell side wall 43 are all perpendicular to shell roof 40 and the external circuit board 2, and shell butt joint wall 41, shell rear wall 42, shell side wall 43 and shell roof 40 are enclosed to form the receiving space 5 of accommodating connector body 3.Offer the interface frame, mating frame mouth 410 that inserts for butt connector on the shell butt joint wall 41.Shell side wall 43 comprises that the shell side wall main body 436 that is provided with base 430 reaches from shell side wall main body 436 to extending near the external circuit board 2 one lateral bucklings and can inserting the installation foot 433 that is installed on the external circuit board 2.Base 430 and the external circuit board 2 are parallel relative and be positioned at shell side wall main body 436 bottom sides.Shell side wall main body 436 also be provided be positioned at base 430 upsides and with the parallel relative upper limbs 435 in base 430, from the base 430 openings 434 that upwardly extending kink 431, the join domains 432 that extend downwards from kink 431 and die-cut installation foot 433 form that tilt.Join domain 432 extends to base 430 from kink 431 along being directed downwards perpendicular to base 430 in the present embodiment.Installation foot 433 from kink 431 to extending away from shell roof 40 directions.Described kink 431 becomes miter angle substantially with base 430 and the external circuit board 2.Installation foot 433 can vertically insert and be installed on the external circuit board 2,430 upsides extend from the base for it, and whole be the sheet that is parallel to shell side wall 43 and perpendicular to base 430, this installation foot 433 comprises from kink 431 to extending near the external circuit board 2 one sides and the root area 4330 relative with shell side wall main body 436 and continue to extend beyond base 430 downwards and can insert installation end 4331 in the installing hole 20 from root area 4330, in the present embodiment, root area 4330 reclines mutually with shell side wall main body 436, so can strengthen the intensity and the stability of installation foot 433, certainly, root area 4330 is also relative at interval with shell side wall main body 436.Opening 434 extends along being parallel to the external circuit board 2 directions.Kink 431 is connected between join domain 432 and the installation foot 433.

See also Fig. 4, it has disclosed the metal shell strip 6 after metal shell 4 expansion, launch the cantilevered leg 437 that strip 6 relative bilateral symmetry are provided with base 430 and supply bending forming installation foot 433, cantilevered leg 437 is parallel to base 430, the cantilevered leg 437 that is parallel to base 430 in the present embodiment is bent the state that is turned into perpendicular to the base 430 and the shell side wall main body 436 that reclines, the strip of installation foot 433 is all taken from shell side wall main body 436, and the manufacturing of installation foot 433 does not increase the consumption of strip fully.

For the technology of existing machine-shaping installation foot, installation foot directly extends downwards from the sidewall edge of metal shell, and making installation foot will increase the strip consumption that width equals installation foot length; The present invention adopts the mode of bending upset moulding installation foot 433, can effectively reduce the consumption of strip.For electric connector 1 of the present invention, installation foot 433 and opening 434 are symmetrically set in the relative both sides of kink 431 substantially, installation foot 433 is perpendicular to base 430, when kink 431 becomes 45 to spend with the angle of the external circuit board 2, the strip of punching molding installation foot 433 is the cantilevered leg 437 in the present embodiment, opening 434 also is positioned on the shell side wall main body 436 fully and is parallel to base 430, and the manufacturing of installation foot 433 at this moment need not to increase the consumption of strip fully; When 2 one-tenth 0 of kink 431 and the external circuit board during to miter angle, the strip of punching molding installation foot 433 can all be taken from shell side wall main body 436, and opening 434 also is positioned at shell side wall main body 436 fully, and this moment, the manufacturing of installation foot 433 need not to increase the consumption of strip fully; When kink 431 is spent greater than 45 degree and less than 90 with the angle of the external circuit board 2, the strip of punching molding installation foot 433 is partly taken from shell side wall main body 436 at this moment, opening 434 also part is positioned at shell side wall main body 436, the manufacturing of installation foot 433 will increase the consumption of strip, but punching molding installation foot 433 strip was tilted to down and extended beyond shell side wall main body 436 this moment, so installation foot 433 and shell side wall main body 436 required strip total amounts still will be saved with respect to prior art; 430 inclinations extend upward kink 431 from the base, installation foot 433 extends from kink 431, because base 430 is comparatively near the external circuit board 2, thereby help reducing the length of installation foot 433, the opening 434 that punching molding installation foot 433 is formed is positioned at the bottom of shell side wall main body 436, shielding properties influence to shell side wall 43 is less, and kink 431 also can be located at other positions of shell side wall main body 436 certainly.

Electric connector 1 of the present invention comprises the shield blade perpendicular to the external circuit board 2, and shield blade is shell side wall 43 in the present embodiment.

The present invention also provides the method for a kind of manufacturing shield blade (shell side wall 43), and this method may further comprise the steps:

1) provides a thin plate strip (not shown);

2) punch out the cantilevered leg 437 that shield blade main body (being shell side wall main body 436 in the present embodiment) and self-shileding sheet Subject Extension go out on described thin plate strip, the bottom side of shield blade main body has and the parallel relative base 430 of the external circuit board;

3) bending and along the bending place to changeing described cantilevered leg 437 near base 430 1 rollover, make cantilevered leg 437 extend beyond base 430 and can insert the installation foot 433 that is installed on the external circuit board to form, installation foot 433 is perpendicular to base 430, the shield blade main body also comprises because of bending and along the bending place changes the kink 431 that described cantilevered leg 437 forms to turning on one's side near base 430 1, described installation foot 433 comprises from kink 431 and extending and the root area relative with the shield blade main body 4330 and extend beyond base 430 and can insert the installation end 4331 that is installed on the external circuit board 2 from root area 4330 that described installation foot 433 is perpendicular to the external circuit board 2.In order to strengthen the intensity of installation foot 433, join domain 432 is reclined mutually with the shield blade main body.
