[embodiment]

Please refer to Fig. 1 and Fig. 2, the utility model electric connector 100 is used for docking with flexible circuit board 50, it has defined the receiving space 101 that runs through forward and the grafting direction (direction from front to back) of flexible circuit board, with the butt end 51 of accommodating flexible circuit board 50, the butt end is provided with conductive pad, because being known techniques, the present embodiment accompanying drawing does not show.

Referring to Fig. 3 and Fig. 4, electric connector 100 comprises insulating body 10, remain in the conducting terminal 20 of insulating body, cover the metal shell 30 of conducting terminal and insulating body and be assembled in the lid 40 of insulating body.

Insulating body 10 is long rectangle, the sidewall 13 that it has diapire 11, the roof 12 parallel with diapire and connects above-mentioned two walls.Diapire 11 has defined by fin 110 isolated some terminal containing slots 111, this accepting groove from the diapire inner surface extend from outside/lower surface, and the first accepting groove 112 length that are positioned at upper surface are much larger than the second accepting groove 113 that is positioned at lower surface.The contact site 22 that conducting terminal 20 comprises holding parts 21, extend back from holding parts and bend forward the weld part 23 that extends to diapire 11 lower surfaces from holding parts, holding parts 21 all is contained in the first accepting groove with contact site 22, the opening part of the contiguous receiving space 101 of holding parts, contact site are then to receiving space 101 inboard extensions.Weld part 23 is contained in the second accepting groove 113 and protrudes from the lower surface of diapire, to weld with printed circuit board (PCB).

The roof 12 of described insulating body 10 is the overarm shape, is positioned at the opening part of receiving space 101, and the back then is exposed shape.The latter half of the inner surface of diapire 11 is the stage portion 114 that exceeds a little, and this stepped portions is in the rear of receiving space 101, and some juts 1141 are formed at this stage portion 114.Described jut 1141 extends along fore-and-aft direction, and its front surface towards receiving space then supplies soft and aligns with accepting groove 111.

Metal shell 30 comprise cover insulating body diapire 11 and sidewall 13 lower wall 31 and two side 33.Sidewall 33 bends inwards and extends to form two retaining sheets 333, and this retaining sheet cooperates with insulating body sidewall 13 and seizes on both sides by the arms in insulating body and is positioned on the sidewall of roof rear side, thereby metal shell 30 is fixed on the insulating body 10.Lower wall 31 is bent to form upper wall 32 at its rear rim place to receiving space 101 directions, and this upper wall is positioned at insulating body roof 12 rear sides and is lower than roof.Upper wall 32 comprises base portion 321 and some elastic portion 322 of tearing and extend to form forward from base portion, in conjunction with Fig. 5, these elastic portion 322 are positioned at the both sides of above-mentioned jut 1141, and its terminal 3211 curved upwards structure, roughly be positioned at conducting terminal contact site 22 directly over, and with contact site at a certain distance between the upper and lower, to use as the earth terminal corresponding with conducting terminal.Described elastic portion 322 and conducting terminal contact site 22 all are exposed in the receiving space 101.

Described metal shell is also torn from base portion 321 and is formed a pair of a pair of elastic arm 34 that is formed at upper wall 32, and this elastic arm extends back from base portion 321 front end both sides, and namely elastic arm 34 is positioned at elastic portion 322 both sides, and elastic arm 34 is arranged side by side with elastic portion 322.Elastic arm 34 has the free terminal 341 that is the elastic protrusion shape and protrudes from upper wall 32, and this free terminal is resisted against on the ground connection contact pad (not shown) that the flexible circuit board upper surface is provided with.

Lid 40 is the space that is housed in insulating body roof 12 rear sides, its be articulated in electric connector pivot part 42, be positioned at the press section 41 of pivot part rear side and be positioned at the pivot part front side with the latch part 43 of hook in flexible circuit board.The two side 33 of metal shell 30 is provided with the pivoting hole 331 with upper end open 3311, and pivot part 42 has the pivotal axis 421 that is articulated in this pivoting hole 331, and realizes the rotation of latch part 43 and press section, rear end 41.Opening 3311 sides of pivoting hole also are provided with stop part 3312, can prevent that pivot part breaks away from pivoting hole in rotation process.Latch part forms some some conduits 44 that run through its front end face, and this conduit is used for accommodating above-mentioned elastic portion 322 roughly corresponding to above-mentioned accepting groove 111 and be positioned at the top of accepting groove.Latch part also comprises the pair of catches arm 431 that is positioned at conduit 44 both sides.

Flexible circuit board 50 has butt end 51, and butt end 51 has defined relative lower surface 501 and upper surface 502, and lower surface 501 is provided with some signal contact pads (not shown), and 502 of upper surfaces are provided with some ground connection contact pads (not shown).With reference to Fig. 6, press down press section 41 especially, because leverage latch part 43 is upwards rotated around pivot part 42, flexible circuit board can be inserted receiving space 101, until flexible circuit board one end is resisted against stage portion 114.Unclamp by pressure arm, because it is subject to the elastic-restoring force of elastic arm 34, latch part rotates, and its lock catch arm 431 is resisted against in the recess 52 that the both sides, butt end are provided with just, can prevent that flexible circuit board from coming off.This moment, the contact site 22 of conducting terminal contacted with the signal contact pad, and 322 of elastic portion compress the function that the ground connection contact pad realizes keeping flexible circuit board and electrical contact.When need taking out flexible circuit board, press down press section 41 and latch part is got final product.Obviously, the operating process of the utility model electric connector is comparatively simple and convenient, has saved the not easy-operating action of lifting.
