Description

Wire and cable connector

The utility model is a kind of wire and cable connector, relates in particular to a kind of wire and cable connector of the LCD of laptop to computer main board that be used to connect.

Wire and cable connector is mainly used in connecting of electric signal between two electronic systems, and it is docked at usually on the input/output end port of electronic system and by its terminal cable and connects as host computer and display, host computer and printer and equipment such as host computer and scanner.Generally be equipped with locking component on this class wire and cable connector, after inserting the craft port of each equipment at wire and cable connector, can cooperate by corresponding mechanism on this locking component and the craft port to lock and wire and cable connector is fixed on this craft port, and the steadiness when keeping both to dock and be beneficial to the signal stable transfer.Common locking component is just like the structures such as plastic cement elastic arm of screw rod, tool projection, and relevant existing design please refer to United States Patent (USP) the 5th, 518, cases such as No. the 85216105th, 86102088, No. 416 and TaiWan, China patent.Yet, the existing wire and cable connector that is disclosed only be suitable for mostly each system and device outer with being connected between other installs, need be for having with the situation of wire and cable connector winding in system and device inside, as LCD (the Liquid Crystal Display that in laptop, links together with main frame, LCD), usually the cable line of engagement cable connector by tool bendable folding endurance is electrically connected on the computer main board, common in this case existing wire and cable connector just is difficult to be suitable for, and needs the structure of functional elements such as its locking of change and ground connection to match with it.And as United States Patent (USP) the 5th, 316,500 and 5,540, though cases such as No. 598 have the structure of the locking component that discloses preferable locking of a kind of tool and ground connection effect, but these existing locking components are to be assembled into behind the independent punch forming on the electric connector again, and the complicated structure of this assembling can not be applicable to that obviously winding is on the wire and cable connector of system and device inside.Moreover, friction interfering edge between the button pin that existing structure is mostly only borrowed locked instrument tool convex interference part and button hole and make electric connector dock unlikely coming off afterwards, but in the laptop that is vibrated often and impact, only depend on unidirectional like this interfering edge effect to be difficult to guarantee that the wire and cable connector butt joint is firm, and the situation that connector is loosening even come off appears easily, cause signal transmission situation unstable or that interrupt to take place.In addition, the locked instrument of most of existing electric connector can only provide the locking effect, the rare shading member that can cooperate constitutes grounded circuit, therefore before and after butt joint unsettled transmission situation is arranged easily, and is unfavorable for the designer trends of present plug and play (Plug and Play).

The purpose of this utility model is to provide a kind of being applicable to connect the wire and cable connector of specific electronic equipment set to computer main board, this wire and cable connector can firmly be fixed on the computer main board of various different thicknesss of slab, and can guarantee its with computer main board on stable the butt joint and the good earth effect between the pin connector, thereby guarantee that the electric signal transmission is stable.

For reaching above-mentioned creation purpose, the utility model wire and cable connector is provided with structures such as connector body, shading member, enclosing cover and locking component, wherein a side of connector body is made as interface, be provided with the passage of accommodating that several connect connector body in from this interface towards connector body, hold several conducting terminals with correspondence, and these conducting terminal one ends are to be connected with the lead of cable.Shading member is coated on outside the connector body, and its interface with respect to connector body is provided with docking port, exposes from this docking port and connects with plug on the computer main board so that this is provided with the interface of accommodating passage.In addition, this connector body that is coated with shading member further is assembled in the enclosing cover, this enclosing cover is provided with port with respect to the interface of connector body, wherein make the usefulness of butt joint for the protruding dew of this interface, cable then can extend into from the opposite side with respect to this port the enclosing cover and be connected with conducting terminal on the connector body.Of the present utility model being characterised in that, extend respectively in the docking port both sides of shading member and to be provided with locking component, each locking component includes near the holding section that is provided with projection suitable length and its extending end and can be buckled in the computer main board lower surface towards extending away from the docking port direction, and extends near near position docking port one end from this holding section and can deduct in the deduction part of computer main board upper surface.Like this, when wire and cable connector docks, can deduct simultaneously on the upper and lower surface of computer main board by locking component, and wire and cable connector firmly is fixed on the computer main board.

According to above-mentioned feature, the holding section comprises mutual tool one determining deviation and preferable flexible two buckling foots of tool, and this two buckling foot mutually away from the terminal position place of a side respectively be provided with at least one projection.

According to above-mentioned feature, the deduction part is to protrude out from this two buckling foots middle part and its bearing of trend and buckling foot bearing of trend formation one flexure strip less than the 90 suitable angles of spending, this flexure strip has the function of automatic adjustment deduction position and can make locked instrument be applicable to that firm button holds the printed circuit board (PCB) of various different thicknesss of slab, and this flexure strip is directly conflicted on the ground path of circuit board and the formation grounded circuit.

According to above-mentioned feature, between distolateral and this shading member of holding section, also be provided with suitably to support and hold kink on the side-flank surfaces of hole, thereby good ground connection further is provided and firmly detains and hold effect at the button of computer main board near the shading member docking port.

Advantage of the present utility model is, by the upper and lower surface of this locking component elasticity deduction simultaneously at computer main board, and wire and cable connector can firmly be docked with the pin connector on the computer main board of being located at various different thicknesss of slab, and set up the ground connection conductive path by locking component and make wire and cable connector tool good anti-static and electromagnetic interference capability.

The utility model is described in further detail below in conjunction with drawings and Examples.
