Embodiment
Please referring to figs. 1 through shown in Figure 6, it has demonstrated the concrete structure of the preferred embodiment of the utility model, and this USB plug connector comprises insulating body 10, is coated on the shield shell 20 outside the insulating body 10 and is accommodated in the terminal group 30 in the insulating body 10.
At first, the orientation of top to bottom, left and right, front and rear that present embodiment is mentioned is a benchmark with direction shown in Figure 1, below will describe the composition architectural characteristic and the installation process of this USB plug connector in detail.
Particularly; As shown in Figure 2; This insulating body 10 is processed with plastic material; This insulating body 10 comprises integrated Plug Division that is positioned at front end 15 and the insulation back seat 14 that is positioned at the rear end, and it can be realized shield shell 20 by being plugged on this Plug Division 15 behind the forward direction, and be blocked on the front end wall of insulation back seat 14.
This Plug Division 15 comprises pedestal 11 and the hyoplastron 12 that extends outward from pedestal 11 front ends below.The upper surface of this hyoplastron 12 offers the several terminal grooves 13 that penetrate into pedestal 11 rear end faces; Each terminal groove 13 level interval is arranged and is provided with; Be used for terminal group 30 inlayed and be fixed on insulating body 10, and the plastic cement of each terminal groove 13 front end is recessed forward goes out a draw-in groove 131.Terminal groove 13 in the present embodiment has four, but its quantity is not as limit.Be respectively equipped with two location notchs 111 on the end face of this pedestal 11 and the bottom surface, these two location notchs, 111 left-right symmetric also maintain spacing, are used for the barrier sheet 21 of the following shield shell 20 of fastening.
The front end face of this insulation back seat 14 is bigger than the area of end face after the insulating body 10, thereby the junction section of being formed with between the Plug Division 15 of insulating body 10 and the insulation back seat 14 is poor.In addition, the bottom surface of this insulation back seat 14 is provided with the breach 143 that communicates with rear end face.The two sides of insulation back seat 14 are the loop configuration of semicircle; Be provided with a plurality of semiorbicular draw-in grooves 144 in these two sides; Be formed with semiorbicular raised line 145 between the adjacent in twos draw-in groove 144, the draw-in groove 144 of insulation back seat 14 two sides in the present embodiment is respectively two that spacing arrangement is provided with.
This shield shell 20 is to process with electric conductivity good metal material, and it is the hollow frame structure of both ends open.On the Plug Division 15 of these shield shell 20 coated insulation bodies 10 front ends; The corresponding above-mentioned location notch 111 in the rear end of shield shell 20 is provided with two barrier sheets 21; This two barrier sheet 21 is fixed in each self-corresponding location notch 111 with the mode that patches fastening; It is to offer breach 22 by the upper surface of shield shell 20, the more downward bending of the sheet metal in the breach 22 is formed, and makes this barrier sheet 21 have certain elastic deformation ability.In the time of in insulating body 10 is inserted into shield shell 20, this barrier sheet 21 is embedded in the location notch 111, thereby shield shell and insulating body 10 lock together.
Hold; Like Fig. 3 and shown in Figure 4; Said terminal group 30 comprises several conducting terminals 31, and each conducting terminal 31 is mounted in the terminal groove 13 of insulating body 10, and each conducting terminal 31 comprises the contact site 311 that is positioned at front end, the holding parts 312 in the middle of being positioned at and be positioned at the weld part 313 of rear end.This contact site 311 is a semi-cylindrical shaped, and is to increase the intensity of conducting terminal 31, not yielding during assembling conducting terminal 31.The bottom surface of this contact site 311 is provided with several interference hangnails 314 that is used to tighten terminal groove 13 inner plastic cement; The head end of this contact site 311 be extended with one have a pinnacle extension 315, the tail end of contact site 311 is the curved end that bending forms, and the front end face of holding parts is the quadrangle end face, the metal of this curved end and quadrangle end face is one to stop syndeton.And; Said holding parts 312 upwards 90 degree bendings extends back and is connected with leg portion 313; Sting plastic cement tightly when making each conducting terminal 31 be embedded in insulating body 10, reduce the pulling function of processing such as follow-up assembling welding to conducting terminal 31, retain strength is effectively strengthened.And weld part 313 is that downward again 90 degree foldings form after the tail end of holding parts 312 stretches out, in order to weld with the PCB circuit board.Conducting terminal 31 in the present embodiment has four, and two conducting terminals 31 that are positioned at both sides are used for ground connection, and two conducting terminals 31 in the middle of being positioned at are used for the transmission of information data.And the leg portion 313 that is used for two conducting terminals 31 of transmitting data information is arranged on the inboard of the leg portion 313 of two conducting terminals 31 that are used for ground connection, maintains spacing between each leg portion 313.
During assembling; Each conducting terminal 31 of this terminal group 30 is inserted in respectively in insulating body 10 each self-corresponding terminal groove 13; The extension 315 of end is embedded in the draw-in groove 131 of terminal groove 13 front ends before each conducting terminal 31, and conducting terminal 31 firmly is installed on this insulating body 10; Then shield shell 20 is inserted on the Plug Division 15 of insulating body 10 from front to back, it is motionless to make barrier sheets 21 in the shield shell 20 be embedded in the location notch 111 of insulating body 10 locking, promptly accomplishes assembling process.
In the use; When this USB flash disk is inserted into butt joint USB socket (not shown); The contact site 311 of conducting terminal 31 pushes against on the terminal of butt joint USB socket; Because the contact site 313 of each conducting terminal 31 is semicircular cylinder structures, USB socket is linear contacts with the contact-making surface of contact site 313, thereby realizes that electric current is connected and the transmission of data.
In sum; The design focal point of the utility model is that it mainly is that the contact site of end before each conducting terminal is processed the semicircle tubular, has solved not high, the yielding problem of conventional thin sheet conducting terminal intensity; With the conducting terminal group shape of this semicircle tubular during at each self-corresponding terminal groove; Intensity is higher, can not cause the distortion of terminal, improves product quality.
Moreover the lower end of the contact site of each conducting terminal is provided with the interference hangnail, and these interfere hangnails to sting the inner plastic cement of terminal groove tightly, reduces follow-up assembling welding etc. and processes the pulling function to conducting terminal, and retain strength is effectively strengthened.
In addition; To the extension that is outside equipped with the pinnacle shape, this extension cooperates with the draw-in groove of terminal groove front end, on the one hand in the leading section of the contact site of each conducting terminal; Resistance when alleviating the terminal installation; When the extension fastening was in draw-in groove, the plastic cement of draw-in groove top was pressed in extension in the terminal groove, avoids conducting terminal to reach the situation that terminal groove causes the product loose contact outward on the other hand.
The above; It only is the preferred embodiment of the utility model; Be not that the technical scope of the utility model is done any restriction; So every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any trickle modification, equivalent variations and modification that above embodiment did.
