Technological means and the decorative effect thereof taked for further setting forth the present invention are described in detail below in conjunction with the preferred embodiments of the present invention and accompanying drawing thereof.
Please referring to figs. 1 through Fig. 8; The present invention provides a kind of connector; This connector 1 comprises insulating body 2, several conducting terminals 4, metal shell 5 and flexible transmission unit 6; The insulating body 2 several terminals slot 26 that has an accommodation space 20 and be located at accommodation space 20 wherein, several conducting terminals 4 are installed in those terminal slots 26.Metal shell 5 is assembled on the insulating body 2; Wherein metal shell 5 is provided with a framework 50 and an operating portion 52; Framework 50 is surrounded insulating body 2; Operating portion 52 is connected in a shell fragment portion 56; This shell fragment portion 56 between operating portion 52 and the framework 50 and operating portion 52 above the upper surface of insulating body 2 with and the upper surface of insulating body 2 between form one and press down stroke space 521, the both sides of operating portion 52 connect a stop portion 54, this stop portion 54 is positioned at accommodation space 20; The framework 50 of metal shell 5, operating portion 52, shell fragment portion 56 and stop portion 54 are the integrated structure of metal stamping, and the shape and structure that the bending of framework 50, operating portion 52, stop portion 54 and shell fragment portion 56 is extended helps metal shell 5 assemblings are fixed on the insulating body 2.
In the present embodiment; For the purpose of the explanation, be the place ahead with the accommodation space of insulating body 2 20 with flexible transmission unit 6 interconnected direction settings, so the opening of accommodation space 20 is the front side that is positioned at insulating body 2 for ease; Insulating body 2 has at least one groove 22; The opening of groove 22 is positioned at the rear side of insulating body 2, and groove 22 is communicated in accommodation space 20, and the vertical height h2 of groove 22 is greater than the vertical height h1 of accommodation space 20.Metal shell 5 is assembled on the insulating body 2 from the rear side of the body 2 that insulate; Framework 50 comprises a lower casing 502 and a back cover 504; Operating portion 52 is up and down with lower casing 502 and is oppositely arranged, but and form a receiving space 51 housing insulation bodies 2 between operating portion 52 and the lower casing 502, back cover 504 connects shell fragment portions 56 and lower casings 502; Stop portion 54 passes groove 22 and is arranged in the accommodation space 20 and between operating portion 52 and lower casing 502, back cover 504 is resisted against the rear side of insulating body 2.
In the present embodiment; Stop portion 54 is connected in the left and right sides of operating portion 52 via a junction 53; The linking arm of the approximate Contraband type formed by a upper arm 531, a side arm 532 and a underarm 533 of connecting portion 53 wherein; The opening of this Contraband type linking arm is toward the opening setting of accommodation space 20, and the opening of Contraband type linking arm can hold flexible transmission unit 6, and stop portion 54 is arranged on the underarm 533.Shell fragment portion 56 is connected in the rear side of operating portion 52, and shell fragment portion 56 is between operating portion 52 and back cover 504, and shell fragment portion 56 comprises several crooked shell fragments; Spacing between those shell fragments equates; So that mechanism's stress equalization, wherein the middle part of back cover 504 connects shell fragment portion 56, back cover 504 each side be provided with a ground strip 58; The ground strip 58 of the left and right sides of back cover 504 is adjacent to stop portion 54; So make flexible transmission unit 6 before being sticked in stop portion 54, what can receive ground strip 58 and conducting terminal 4 earlier seizes the location up and down on both sides by the arms, and obtains the preferable effect that is fixed.
In addition; In the present embodiment, the upper surface of insulating body 2 also is provided with a depressed part 24, and operating portion 52 is positioned at depressed part 24; And the sidepiece 28 of the left and right sides of depressed part 24 is higher than operating portion 52, so can protect operating portion 52 can not receive external force collision easily and destroys.In addition, form this between the bottom surface of operating portion 52 and depressed part 24 and press down stroke space 521.
The front end of conducting terminal 4 has a contact jaw, and the rear end of conducting terminal 4 has a welding ends, and contact jaw is positioned at accommodation space 20, and the welding ends extension protrudes from outside the insulating body 2.In the present embodiment, the contact jaw and the flexible transmission unit 6 that are arranged in the conducting terminal 4 of accommodation space 20 electrically connect, and the welding ends and circuit board (not illustrating) welding that protrude from the conducting terminal 4 outside the insulating body 2 are fixing.
Flexible transmission unit 6 is inserted in the accommodation space 20, and wherein flexible transmission unit 6 is provided with a breach 62, and breach 62 can be sticked in stop portion 54, so as to flexible transmission unit 6 is fixed in insulating body 2.Flexible transmission unit 6 is provided with a metal level (not illustrating), and metal level electrically overlaps in order to the ground strip 58 with 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 the present embodiment; Stop portion 54 is the holding section that raises up; One side of the holding section that wherein raises up is the inclined-plane, and opposite side then is the metal clips structure of vertical plane, so design can be beneficial to the breach 62 that is sticked in flexible transmission unit 6 and avoid engaging after the problem that gets loose.Because the openings of sizes essence of accommodation space 20 equals or is slightly larger than approximately the sectional area size of flexible transmission unit 6; After seeing through the downward application of force effect of operating portion 52, stop portion 54 can move to the groove 22 from accommodation space 20 strains; So breach 62 no longer is sticked in stop portion 54, and flexible transmission unit 6 then can break away from insulating body 2.
In sum; Connector of the present invention; It is through being coated with a metal shell on insulating body, utilize the ground strip of this metal shell can closely be overlapped in the characteristic of the metal level on the flexible transmission unit, sees through the grounding parts ground connection of this metal shell afterwards again; So can reach the effect that prevents the external electromagnetic wave interference, to solve that existing connector receives the external electromagnetic wave interference easily and the problem that causes the visitor to tell.In addition; Also be provided with integrally formed operating portion, stop portion and shell fragment portion on this metal shell; Can be used to replace the purpose that the loam cake that has connector now reaches the snap fit flexible transmission unit; Therefore, connector of the present invention, the structural design of its metal shell has the dual-use function that is fixed and prevents Electromagnetic Interference.
The above for the person of ordinary skill of the art, can make other various corresponding changes and distortion according to technical scheme of the present invention and technical conceive, and all these changes and distortion all should belong to the protection range of claim of the present invention.
