Refer to shown in Fig. 1 and Fig. 2, electric connector 1 of the present invention is heavy board-like RJ45 connector, it can be installed on the external circuit board 2 along the installation direction of vertical external circuit board 2 and can coordinate with butt connector (not shown), and it comprises the metal shell 4 of connector body 3 and coated connector body 3.The external circuit board 2 is provided with installing hole 20.
Refer to shown in Fig. 1-3, metal shell 4 comprises relative shell roof 40 parallel with the external circuit board 2, on front side of shell roof 40, dock wall 41 to the shell of downward-extension, docks the relative shell rear wall 42 of wall 41 and bend the shell side wall 43 to downward-extension from shell roof 40 arranged on left and right sides on rear side of shell roof 40 to downward-extension and with shell.Shell docking 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 docking wall 41, shell rear wall 42, shell side wall 43 and shell roof 40 are enclosed to form the receiving space 5 of collecting connector body 3.Shell docking wall 41 offers the interface frame, mating frame mouth 410 inserted for butt connector.Shell side wall 43 comprise the shell side wall main body 436 that is provided with base 430 and from shell side wall main body 436 to extending near the external circuit board 2 one lateral buckling and the installation foot 433 being installed on the external circuit board 2 can being inserted.Base 430 and the external circuit board 2 are parallel relative and be positioned at shell side wall main body 436 bottom side.Shell side wall main body 436 be also provided with to be positioned on the upside of base 430 and with the parallel relative upper limb 435 in base 430, tilt upward from base 430 extension kink 431, from kink 431 to the opening 434 that the join domain 432 of downward-extension and die-cut installation foot 433 are formed.Join domain 432 extends downward base 430 from kink 431 along perpendicular to direction, base 430 in the present embodiment.Installation foot 433 extends to away from shell roof 40 direction from kink 431.Described kink 431 becomes miter angle substantially with base 430 and the external circuit board 2.Installation foot 433 vertically can insert and be installed on the external circuit board 2, it extends on the upside of base 430, and entirety in be parallel to shell side wall 43 sheet and perpendicular to base 430, this installation foot 433 comprises from kink 431 to extending near the external circuit board 2 side and the root area 4330 relative with shell side wall main body 436 and continue to extend beyond base 430 downwards from root area 4330 and can insert the installation end 4331 in installing hole 20, in the present embodiment, root area 4330 reclines mutually with shell side wall main body 436, so can strengthen intensity and the stability of installation foot 433, certainly, it is relative that root area 4330 and shell side wall main body 436 may also be interval.Opening 434 extends along being parallel to the external circuit board 2 direction.Kink 431 is connected between join domain 432 and installation foot 433.
Refer to Fig. 4, there is disclosed the metal shell material strip 6 after metal shell 4 expansion, launch the relative bilateral symmetry of material strip 6 and be provided with base 430 and the cantilevered leg 437 for bending forming installation foot 433, cantilevered leg 437 is parallel to base 430, the cantilevered leg 437 being parallel to base 430 in the present embodiment is bent and is turned into perpendicular to base 430 and the state of the shell side wall main body 436 that reclines, the material strip of installation foot 433 all takes from shell side wall main body 436, and the manufacture of installation foot 433 does not increase the consumption of material strip completely.
For the technology of existing machine-shaping installation foot, installation foot stretches out directly to downward from the sidewall edge of metal shell, and making and installation pin will increase the material strip consumption that width equals installation foot length; The present invention adopts the mode of the shaping installation foot 433 of bending upset, can effectively reduce the consumption of material strip.For electric connector 1 of the present invention, installation foot 433 is located at the relative both sides of kink 431 with opening 434 symmetrical, installation foot 433 is perpendicular to base 430, when kink 431 to become 45 degree with the angle of the external circuit board 2, the material strip of punching molding installation foot 433 is the cantilevered leg 437 in the present embodiment, opening 434 to be also positioned at completely in shell side wall main body 436 and to be parallel to base 430, and the now manufacture of installation foot 433 is completely without the need to increasing the consumption of material strip; When kink 431 and the external circuit board 2 one-tenth 0 to miter angles, the material strip of punching molding installation foot 433 can all take from shell side wall main body 436, and opening 434 is also positioned at shell side wall main body 436 completely, and the now manufacture of installation foot 433 is completely without the need to increasing the consumption of material strip; When kink 431 is greater than 45 degree with the angle of the external circuit board 2 and is less than 90 degree, now the material strip part of punching molding installation foot 433 takes from shell side wall main body 436, opening 434 also part is positioned at shell side wall main body 436, the manufacture of installation foot 433 will increase the consumption of material strip, but now the material strip of punching molding installation foot 433 is tilted to downward-extension and exceeds shell side wall main body 436, so installation foot 433 still will be saved relative to prior art with the material strip total amount needed for shell side wall main body 436; Kink 431 tilts upward extension from base 430, installation foot 433 extends from kink 431, because base 430 is comparatively close to the external circuit board 2, thus be conducive to the length reducing installation foot 433, the opening 434 simultaneously making punching molding installation foot 433 be formed is positioned at the bottom of shell side wall main body 436, less on the shielding properties impact of shell side wall 43, certain kink 431 also can be located at other positions of shell side wall main body 436.
Electric connector 1 of the present invention comprises the shielding sheet perpendicular to the external circuit board 2, shields sheet in the present embodiment and is shell side wall 43.
The present invention also provides a kind of method manufacturing shielding sheet (shell side wall 43), and the method comprises the following steps:
1) a thin plate material strip (not shown) is provided;
2) on described thin plate material strip, punch out the cantilevered leg 437 that shielding sheet main body (being shell side wall main body 436 in the present embodiment) and self-shileding sheet main body are extended, the bottom side of shielding sheet main body has relative base 430 parallel with the external circuit board;
3) bend and overturn described cantilevered leg 437 along bending place near side, base 430, make cantilevered leg 437 extend beyond base 430 and can insert to be formed the installation foot 433 being installed on the external circuit board, installation foot 433 is perpendicular to base 430, shielding sheet main body also comprises because of bending and the kink 431 formed to overturning described cantilevered leg 437 near side, base 430 along bending place, described installation foot 433 comprises and extending and the root area 4330 relative with shielding sheet main body and extend beyond base 430 from root area 4330 and can insert the installation end 4331 being installed on the external circuit board 2 from kink 431, 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 can be made to recline mutually with shielding sheet main body.
