Embodiment
Please referring to figs. 1 through the preferred embodiment shown in 6, the utility model provides a kind of electric connector 1 can use with flexible transmission unit 6 to link each other, and electric connector 1 mainly comprises insulating body 2, several conducting terminals 4 and metal shell 5.
In the present embodiment; Operating portion 27 passes passage 22 and extends to and protrude from outside the insulating body 2; Free end in shell fragment portion 23 is provided with sticking department 25; Shell fragment portion 23 comprises one first horizontal part 231 that extends from body 2 bottoms of insulating, from a kink 233 of first horizontal part, 231 terminal upwards reflexeds and from kink 233 terminal one second horizontal parts 235 that extend; First horizontal part 231 and second horizontal part 235 is oppositely arranged up and down so that shell fragment portion 23 is the U font, and second horizontal part 235 extends towards the opening of accommodation space 20.The opening direction that sticking department 25 is intended for accommodation space 20 is provided with a guiding incline 251, and the opening direction in accommodation space 20 is provided with a vertical plane 253 dorsad.During certain position, the breach 62 of flexible transmission unit 6 both sides can interact with sticking department 25, to reach the purpose that stopping is fixed in flexible transmission unit 6 one ends get into accommodation space 20.
Several conducting terminals 4 are installed in the terminal slots 26 of insulating body 2.Each conducting terminal 4 has one and is positioned at the contact jaw 41 of accommodation space 20 and extends the welding ends of starting from outside the insulating body 2 42; Contact jaw 41 can electrically contact with the flexible transmission unit 6 in inserting accommodation space 20 each other, and 42 of welding endss are fixedly welded on the external circuit board.
When flexible transmission unit 6 was inserted in the accommodation space 20, the sticking department 25 of elasticity stop portion 28 can be interfered the breach 62 in flexible transmission unit 6, so as to flexible transmission unit 6 is fixing.During practical operation, the user can point down and be pressed on operating portion 27, so that shell fragment portion 23 pushes away downwards; Driving sticking department 25 simultaneously moves down; For example when user's desire is inserted electric connectors 1 with flexible transmission unit 6, can first press operating part 27, insert flexible transmission unit 6 again; Then releasing operation portion 27 again moves up sticking department 25 and engages with breach 62.Same, when desire is taken out flexible transmission unit 6, can first press operating part 27, extract flexible transmission unit 6 again, to reach the purpose of release.Press operating part 27 not because sticking department 25 itself has the design of guiding incline 251, inserting 6 stages of flexible transmission unit in addition, even also can reach the purpose of location engaging.
In the present embodiment; Operating portion 27 can not interfere with flexible transmission unit 6 when moving up and down; Therefore in design, sticking department 25 more is close to flexible transmission unit 6 than operating portion 27, shown in the sectional axonometric drawing of Fig. 5, because sticking department 25 all is arranged on the free end of shell fragment portion 23 with operating portion 27; So the position of sticking department 25 must more be close to flexible transmission unit 6 than operating portion 27, so make operating portion 27 can not hamper withdrawing from of flexible transmission unit 6 doing the time spent.Operating portion 27 comprises a press section 271 and a location division 273; Press section 271 is positioned at outside the framework 50; Location division 273 is positioned at framework 50, but so makes operating portion 27 receive the restriction of location division 273 and can stably in framework 50, move up and down and do not hinder the user to operate press section 271.
Flexible transmission unit 6 is located between grounding elastic part 56 and the conducting terminal 4, therefore can receive the last down spring that strain caused that comes from grounding elastic part 56 and conducting terminal 4 and seize on both sides by the arms.The sticking department 25 of the elasticity stop portion 28 of the electric connector 1 of the utility model, grounding elastic part 56 and conducting terminal 4 all are to utilize the interference of above-below direction to engage or seize on both sides by the arms; Reach the fixedly purpose of flexible transmission unit, the effect that so can obtain comparatively stably electrically connecting.
What deserves to be mentioned is; In the present embodiment; The shell fragment portion 23 of elasticity stop portion 28 is U font structure from the bottom extension of insulating body 2; So be not limited thereto, also can shell fragment portion 23 be extended out from the two side or the rear wall of insulating body 2, move up and down as long as it can provide sticking department 25 and operating portion 27 to produce.
Flexible transmission unit 6 is provided with a metal level, and metal level electrically contacts with the grounding elastic part 56 of metal shell 5.In the present embodiment, this flexible transmission unit 6 is flexible flat cable (FFC), and this metal level is an aluminium foil, so is not limited thereto, and flexible transmission unit 6 also can be flexible printed wiring board (FPC), and this metal level also can be the elargol coating.
In sum; It is provided with an elasticity stop portion electric connector of the utility model on insulating body; By moving up and down of this elasticity stop portion of control; Reach and seize the fixedly purpose of flexible transmission unit on both sides by the arms; Therefore this kind seized the reliability that fixing mode more can not have influence on the electric connection between flexible transmission unit and the conducting terminal up and down on both sides by the arms, and it is good to solve the reliability that electrically connects between flexible flat cable that existing electric connector is easy to generate and the conducting terminal, and what caused is easy to generate the problem that the visitor tells.In addition, elasticity stop portion and insulating body are one-body molded, can reach the effect that reduces manufacturing cost.Moreover; The electric connector of the utility model also is provided with several grounding elastic parts on metal shell; The slit that forms between grounding elastic part and the conducting terminal can be used to seize on both sides by the arms flexible transmission unit; So not only can reach between flexible transmission unit and the conducting terminal firmly outside the electrical connection; And can reach the purpose that grounding elastic part closely is overlapped in the metal level on the flexible transmission unit, and see through the grounding parts ground connection of this metal shell afterwards again, also can reach the effect that prevents the external electromagnetic wave interference.
The above; For the person of ordinary skill of the art; Can make other various corresponding changes and distortion according to the technical scheme and the technical conceive of the utility model, and all these changes and distortion all should belong to the protection range of the utility model claim.
