Embodiment

See also Fig. 1 to Fig. 8, a kind of electric connector socket 100 as display interface, its inside electrical connector plug that is complementary with it 800 of can pegging graft.

This electric connector socket 100 comprises a shielding casing 1, an insulating body 3 and plurality of conductive terminals 5.

This shielding casing 1 is to be formed by metallic plate integrated punching bending engaging, and it comprises end face 16, a bottom surface 18 and a back shield 20 on a left side wall 12, the right side wall 14.

This left side wall 12 is two arc transition faces 122 with last end face 16 and bottom surface 18 in the transition junction of open front place, this right side wall 14 also is two arc transition faces 142 with last end face 16 and bottom surface 18 in the transition junction of open front place, the radius bend of arc transition face 122 inwalls is 1.4mm in the present embodiment, and the radius bend of arc transition face 142 inwalls is 0.3mm.Wherein right side wall 14 and arc transition face between the bottom surface 18 142 that the arc transition face between left side wall 12 and the last end face 16 122 reaches and it is in relative position constitutes one group of arc transition face 122,142; And constitute another group arc transition face 122,142 at right side wall 14 and arc transition face between the last end face 16 142 that the arc transition face between left side wall 12 and the bottom surface 18 122 reaches and it is in relative position.The radius bend of these two groups relative arc transition face 122,142 inwalls is inequality, thereby its shape is asymmetric, thereby constitutes the first heavy anti-mis-insertion structure.

Each stretches out two fixing pin 132,134 downwards this left side wall 12 and right side wall 14, and extends back a cramp 136.The fixing pin 132,134 of these both sides is used for being plugged into the upward corresponding jack (figure does not show) of a circuit board (figure does not show) under it thereby this shielding casing 1 is fixed.The bending back, two ends of this shielding casing 1 is fastened togather at the junction surface 182 of this bottom surface 18.

This back shield 20 is that the end edge of end face 16 extends on this, each side being provided with and extending pin 204 of 20 times ora terminalis of this back shield, thus make this back shield 20 formation one [following ora terminalis of shape.Should bend downwards by back shield 20 during assembling, make this left side wall 12, right side wall 14, go up end face 16, bottom surface 18 and back shield 20 surround formation cavitys (not label).Wherein thereby the bending transition position of this back shield 20 and last end face 16 is provided with two grooves 202 and conveniently bends.[the following ora terminalis of shape can increase the shielding surface of shielding casing 1 as much as possible, reduces the electromagnetic radiation that conducting terminal 5 produces and leak when carrying out the signal high-speed transfer, guarantees that elements on circuit board normally stably works for this back shield 20 this.In addition when these conducting terminals 5 fail to be welded on the circuit board well, welding gun also can [the following ora terminalis of shape stretches into, and the conducting terminal of failing to be welded to well on the circuit board 5 is processed again from this.

This insulating body 3 can hold in the cavity that is installed in this shielding casing 1 formation, and it comprises a front end face 32, a rear end face 34, two side 36, one top end faces 38 and a bottom face 40.Stretch out a hyoplastron 322 before the mediad of this front end face 32, this hyoplastron 322 includes relative up and down a upper surface 3222 and a lower surface 3224.Be concaved with several terminal channels 3226 on this upper surface 3222 and the lower surface 3224.A block wall 3228 is extended in each bending downward vertically of the both sides of this hyoplastron 322, form and one be [structure of shape, thus constitute the second heavy anti-mis-insertion structure.

These insulating body 3 front end faces 32 bottoms stretch out three tabs 324 forward, and the bottom of its central tab 324 also stretches out a retaining column 3242 downwards.This retaining column 3242 can match with corresponding through hole on the circuit board (figure does not show), prevents the front and back slippage when electrical connector plug 800 plugs of this insulating body 3, and the conducting terminal 5 that causes being welded on the circuit board damages.This tab 324 is under the support of this retaining column 3242, thereby support prevents that below the junction surface 182 of this shielding casing 1 bottom surface 18 this shielding casing 1 from deforming.On this rear end face 34 to should upper surface 3222 and the terminal channel 3226 of lower surface 3224 offer several vertical draw-in grooves 342.This insulating body 3 respectively is provided with a fixture block 344 at its top end face 38, rear end face 34 with the junction of left and right sides wall 36, this two fixture block 344 is fastened on respectively between the cramp 136, left and right sides sidewall (12,14) and back shield 20 of this shielding casing 1, thus with these insulating body 3 positioning and fixing to this shielding casing 1.

Each conducting terminal 5 comprises a body 52, and an end of this body 52 continues bending and extends a docking part 54, and the other end of this body 52 continues bending and extends a weld part 56.The docking section 54 of these conducting terminals 5 plugs successively and fixes in the terminal channel 3226 of the terminal channel 3226 of the upper surface 3222 of this hyoplastron 322 and lower surface 3224.This body 52 is packed in the draw-in groove 342 of these insulating body 3 rear end faces 34, and these conducting terminals 5 are separated one by one.The weld part 56 of these conducting terminals 5 extends between the pin 204 horizontal-extending and goes out from two of this back shield 20, and correspondence is welded on the circuit board.

When assembling, earlier with these conducting terminal 5 corresponding inserted in the terminal channel 3226 of the terminal channel 3226 of the upper surface 3222 of this hyoplastron 322 and lower surface 3224, and its body 52 is installed in each self-corresponding draw-in groove 342 respectively, then the after-opening of this insulating body 3 from this shielding casing 1 is inserted in this shielding casing 1, hyoplastron 322 is extend in the cavity of this shielding casing 1, and this tab 324 amplexiforms below shielding casing 1 bottom surface 18, then will this back shield 20 and cramp 136 bendings seal the rear end face 34 of this insulating body 3, thereby this insulating body 3 is set firmly on this shielding casing 1, can finish the assembling of this electric connector socket 100.

The back shield 20 of electric connector socket 100 of the present utility model prevents that through bending rear enclosed most of area of living this shielding casing 1 rear end the electromagnetic radiation that conducting terminal 5 sends from leaking, and has guaranteed that the element on the circuit board can normally stably work; In addition because this back shield 20 is the end edges of end face 16 from this shielding casing 1 bends and extend, therefore can when making shielding casing 1, make in the lump, be assembled into shielding casing 1 again after need not making separately, do not worry that also this back shield 20 can come off from shielding casing 1, it is easily manufactured reliable.
