For making the object, technical solutions and advantages of the present invention clearly, describe the present invention below in conjunction with the drawings and specific embodiments.
As shown in Figures 1 and 2, be schematic perspective view of the present invention and perspective exploded view.As shown in the figure, electric connector of the present invention, mainly be applied in a circuit board (not shown), and be electrically connected a docking object (as the enlargement module in order to circuit board to expand such as DDR, PCI, PCIExpress, MiniPCI, NGFF).Electric connector 40 of the present invention includes insulating body 10, terminal module 20 and two stators 30.Wherein:
The front end of insulating body 10 is provided with a socket 11 that can insert for docking object, and the upper and lower both sides in its socket 11 are formed with plural upper end pilot trench 12 and plural lower end pilot trench 13 respectively, and the arranged on left and right sides of socket 11 is distinctly provided with a holddown groove 14.
Terminal module 20 is located in insulating body 10, includes plural metal terminal 21 and a holder 22.Those metal terminals 21, have part to be exposed in the socket 11 of insulating body 10, in order to be electrically connected with docking object.Those metal terminals 21 fixed by holder 22, and the left and right sides of holder 22 is distinctly provided with a draw-in groove 23.
In the present embodiment, metal terminal 21 includes plural the first metal end 211 and plural second metal terminal 212, its the first metal end 211 is the tops being fixed on holder 22, and have part to extend in the upper end pilot trench 12 of insulating body 10, and there is place above the socket 11 being exposed to insulating body 10 partly; Second metal terminal 212 is then the below being fixed on holder 22, and has part to extend in the lower end pilot trench 13 of insulating body 10, and has place below the socket 11 being exposed to insulating body 10 partly.
Each stator 30, is provided in the holddown groove 14 of insulating body 10, and each holddown groove 14 is extended with a buckle 31 along terminal module 20 direction, and its buckle 31 mutually fastens with the draw-in groove 23 of terminal module 20 in insulating body 10.And each stator 30 is also provided with a weld part 32 and at least one hangnail 33, its weld part 32 is welded on circuit board, and hangnail 33 is then provided at the side of stator 30, in order to be fixed in the holddown groove 14 of insulating body 10 by stator 30.
Shown in Fig. 3, it is the perspective exploded view at another visual angle of the present invention.As shown in the figure, insulating body 10 of the present invention, its rear end is also formed with an accommodation space 15, its accommodation space 15 is formed with aforementioned socket 11 and is communicated with, its terminal module 20 is located in accommodation space 15, makes those the first metal end 211 and those second metal terminals 212 be able to the convex of part through those upper end pilot trench 12 aforementioned and those lower end pilot trench 13 aforementioned and is exposed in socket 11.
In addition, the arranged on left and right sides of the accommodation space 15 of insulating body 10 is respectively arranged with a guide channel 16, and its guide channel 16 is interconnected with aforementioned holddown groove 14 respectively.And the arranged on left and right sides of holder 22 is relative to the position of guide channel 16, also distinctly have additional a guiding block 24, its draw-in groove 23 is located on guiding block 24.
Moreover, those the first metal end 211 are also extended with one in holder 22 rear and ranked first weld part 2111, and the second metal terminal 212 is also extended with two below holder 22 ranked second weld part 2121, those first weld parts 2111 are in order to electrical communication on circuit board with those second weld parts 2121, make its docking object and circuit board form the effect of electrically connect.
Please coordinate shown in Fig. 4, be generalized section of the present invention simultaneously.As shown in the figure, during electric connector assembling of the present invention, be after being utilized by terminal module 20 guiding block 24 to correspond to the guide channel 16 of insulating body 10, then terminal module 20 is installed in insulating body 10, terminal module 20 is incorporated in the accommodation space 15 of insulating body 10.
Then, after each stator 30 is corresponded to holddown groove 14, be installed in holddown groove 14 one by one by each stator 30 again, its each stator 30 utilizes hangnail 33 to produce chimeric effect with the cell wall in holddown groove 14, and then prevented coming off of stator 30.
In addition, when stator 30 is installed in holddown groove 14, because stator 30 front end is extended with a buckle 31, its buckle 31 forms with the draw-in groove 23 on guiding block 24 state mutually fastened by extending in guide channel 16, and then make stator 30 and terminal module 20 produce the state mutually pullled in the direction of inserting, and then the phenomenon that can prevent terminal module 20 and stator 30 from coming off from the direction of insertion of insulating body 10.
It is worth mentioning that, in the present invention, terminal module 20 mainly reaches with the draw-in groove 23 of holder 22 state mutually fastened by the buckle 31 of each stator 30 front end, therefore insulating body 10 does not need to set up snap device in addition again, still can reach in a limited space and effectively fasten effect, and then the height of insulating body 10 can be effectively reduced, make electric connector meet the requirement of slimming.
In addition, the slimming requirement of electric connector can more be met, shown in Fig. 5, for terminal module of the present invention second implements the decomposing schematic representation of aspect.As shown in the figure, terminal module 20 of the present invention is except including the first metal end 211 and the second metal terminal 212, and its holder 22 also includes one first holder 221 and one second holder 222.Those the first metal end 211 are fixed in injection molding mode by its first holder 221; Those second metal terminals 212 are fixed with injection molding side by the second holder 222, and guiding block 24 is located at the arranged on left and right sides of the second holder 222.
And the first holder 221 is also provided with a location hole 2211 along the orientation of the first metal end 211, its location hole 2211 runs through the first holder 221, and the first metal end 211 of part is exposed in location hole 2211.
And the second holder 222 is also convexly equipped with a location division 2221 towards the first holder 221 direction, its location division 2221 extends along the orientation of the second metal terminal 212, and it is corresponding with the location hole 2211 of the first holder 221, and above location division 2221, also having additional plural groove 2222, each groove 2222 is corresponding with the first metal end 211 that each is exposed to location hole 2211.
Thus, when the first holder 221 and the second holder 222 combine, utilize the location division 2221 of the second holder 222 to be embedded in the location hole 2211 of the first holder 221, and the first metal end 211 making each be exposed in location hole 2211 embeds in the groove 2222 of each correspondence, and then the first holder 221 and the second holder 222 are embedded mutually.
What deserves to be explained is, because the first holder 221 and the second holder 222 take shape on the first metal end 211 and the second metal terminal 212 in injection molding mode respectively, therefore, it is possible to make the first holder 221 and the second holder 222 reach the requirement of better slimming.And the first holder 221 and the second holder 222 are the modes overlapped with thickness, that is the effect utilizing location division 2221 and location hole 2211 to reach thickness to overlap, therefore the thickness of the first holder 221 and the second holder 222 can effectively be reduced, the thickness of its integral terminal module 20 is reduced, the relative reduction in bulk that also can make insulating body 10, and then overall electric connector can be made more to meet the requirement of slimming.
Although technology contents of the present invention describes as above with preferred embodiment; so itself and be not used to limit the present invention; those skilled in the art do not depart from of the present invention spirit do a little change and retouching; all should be covered by category of the present invention, the content that therefore protection scope of the present invention defines when the right depending on application is as the criterion.
