Embodiment
Below the present invention is described in detail.
Embodiment one, referring to Fig. 1, a kind of USB connector 51, be used for plugging with the USB female seat, this equipment comprises: metal leg 11, connecting line 12 and matrix 13, one end of metal leg 11 is connected with an end of connecting line 12, the other end of connecting line 12 is used for being connected with pcb board, and metal leg 11 is formed at matrix 13 surfaces, and connecting line 12 is fixed on matrix 13 surfaces.The metal leg is formed at matrix 13 surfaces; The size of USB connector depends primarily on matrix 13, as long as matrix 13 is satisfied with the thickness that the USB female seat is pegged graft, thereby on the basis that guarantees USB connector function, reduce the thickness of USB connector, and then reduce the thickness of USB device, make the thickness of USB device significantly reduce with respect to the prior USB product, it is little to take up room, both be easy to carry, satisfied people in the modern life again, improved practicality and the aesthetic property of USB device electronic product exquisiteness, brief pursuit.
Further, when the thickness of matrix 13 greater than 2.45mm, may make the USB connector be difficult to insert the USB female seat; When the thickness of matrix 13 less than 2.2mm, may make that the USB connector inserts the USB female seat after, and the excesssive gap between the USB female seat reduces the stability of USB connector and the grafting of SUB female seat, therefore, the thickness of matrix 13 is 2.2mm-2.45mm.
The method that can adopt in-mould injection or heat to insert is fixed on matrix 13 surfaces with metal leg 11.Further,, can metal leg 11 be embedded matrix 13 surfaces at matrix 13 surface flutings in order to improve the bonding strength of metal leg 11, one-body molded with matrix 13; Perhaps the mode by corrosion makes metal leg 11 be formed at matrix 13 surfaces, for example, forms metal leg 11 by the mode of revealing copper on matrix 13 surfaces.
Further, in order to guarantee and the performance that is electrically connected of USB female seat grafting that the surface of metal leg 11 is not less than the surface of place matrix 13; The apparent height that metal leg 11 exceeds place matrix 13 may cause the USB connector to be difficult to insert the USB female seat during greater than 0.2mm, and therefore, the apparent height that metal leg 11 exceeds place matrix 13 is 0-0.2mm.
Further, in order improving the useful life of USB connector,, can to prevent that airborne pollutant from carrying out oxidation etc. to metal leg 11, also can to avoid the user to contact infringements such as corrosion metal leg 11 in metal leg 11 surface gold-plating or silver-plated etc.
Further; in order to improve electrostatic protection (ESD) to the USB connector; connecting line 12 also comprises earth terminal 121; earth terminal 121 is used for being connected with the ground wire of pcb board; matrix 13 has metal level 14 with metal leg 11 facing surfaces; metal level 14 is connected by sheet metal 15 with earth terminal 121, thereby realizes esd protection.Further, metal level 14 can adopt stainless steel layer, can improve the corrosion resistance of metal level 14, thereby prolongs the useful life of USB connector.Further, sheet metal 15 can be run through matrix 13, an end of sheet metal 15 is connected with the earth terminal 121 of connecting line 12, and the other end is connected with metal level 14, outside the USB connector that assembles, cannot see sheet metal 15 like this, thereby improve the aesthetic property on the USB connector profile.Can adopt ultrasonic bonding, method such as bonding that metal level 14 is fixed on the matrix 13, guarantee that metal level 14 contacts with the good of sheet metal 15.
Further, in order to improve the stability of USB connector, connecting line fixed mount 16 is set also, connecting line fixed mount 16 covers connecting line 12.Connecting line fixed mount 16 is used for connecting line 12 is fixed on matrix 13, and the material of connecting line fixed mount 16 can be the injection moulding plastic cement, also can be PUR, can injection moulding plastic cement or PUR be processed into connecting line fixed mount 16 by the mode of injection mo(u)lding.With the space between injection moulding plastic cement or PUR heating back filling connecting line 12 and the matrix 13, the cooling back forms connecting line fixed mount 16.
Further, in order to improve the practicality of USB connector, be provided for preventing the anti-error-proof structure of inserting 17, error-proof structure 17 takes shape in matrix 13 surfaces.When the user inserts the USB female seat with USB connector 51, the one side that is provided with error-proof structure 17 is made progress, make metal leg 11 well contact, thereby prevent that by error-proof structure 17 the USB connector is oppositely inserted the USB female seat to be caused short circuit or do not have function with the USB female seat.Because when matrix 13 is pegged graft with the USB female seat, have the gap between matrix 13 surfaces and the USB female seat inwall, error-proof structure 17 can be housed in this gap, therefore can adopt general USB female seat and the USB connector in the present embodiment 51 to peg graft.In addition, error-proof structure 17 can symmetry or asymmetric matrix 13 surfaces that are distributed in, and is preferred, error-proof structure 17 symmetries be distributed in matrix 13 surfaces, improve the aesthetic property of USB connector profile, also be convenient to processing.Optionally, error-proof structure 17 can perhaps be symmetrically distributed in the projection of matrix 13 surperficial both sides for being distributed in the projection of matrix 13 surperficial sides.
