In the present embodiment, metal terminal 21 includes plural the first metal end 211 and plural the second metal terminal 212, its the first metal end 211 is tops of being fixed on holder 22, and there is part to extend in the upper end pilot trench 12 of insulating body 10, and have the socket that is exposed to insulating body 10 11 places, top of part; The second metal terminal 212 is the below of being fixed on holder 22, and has part to extend in the lower end pilot trench 13 of insulating body 10, and has the socket that is exposed to insulating body 10 11 places, below of part.
Each stator 30, is to be located in the holddown groove 14 of insulating body 10, and each holddown groove 14 is extended with a buckle 31 along terminal module 20 directions, and its buckle 31 is mutually to fasten with the draw-in groove 23 of terminal module 20 in insulating body 10.And be also provided with a weld part 32 and at least one hangnail 33 on each stator 30, its weld part 32 is to be welded on circuit board, hangnail 33 is a side of being located at stator 30, in order to stator 30 is fixed in the holddown groove 14 of insulating body 10.
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 forms and is communicated with aforementioned socket 11, its terminal module 20 is located in accommodation space 15, and those the first metal ends 211 and those second metal terminals 212 are able to through aforementioned those upper end pilot trench 12 and aforementioned those lower end pilot trench 13 and protruding being exposed in socket 11 of part.
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 with respect 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 rears and ranked first weld part 2111, and being also extended with two in holder 22 belows, the second metal terminal 212 ranked second weld part 2121, those first weld parts 2111 are to be electrically linked 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 that terminal module 20 is utilized after the guide channel 16 of guiding block 24 corresponding to 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, by each stator 30 corresponding to holddown groove 14 after, each stator 30 is installed in holddown groove 14 one by one, its each stator 30 is to utilize hangnail 33 and the cell wall in holddown groove 14 to produce chimeric effect, and then is prevented coming off of stator 30 again.
In addition, in stator 30 is installed on holddown groove 14, because stator 30 front ends are extended with a buckle 31, its buckle 31 forms by the draw-in groove 23 extending in guide channel 16 and on guiding block 24 state mutually fastening, and then make stator 30 in the direction of inserting, produce the state of mutually pullling with terminal module 20, and then can prevent the phenomenon that terminal module 20 and stator 30 come off from the direction of insertion of insulating body 10.
It is worth mentioning that, in the present invention, terminal module 20 is mainly the state of mutual fastening that reaches by the buckle 31 of each stator 30 front end and the draw-in groove 23 of holder 22, therefore on insulating body 10, do not need to set up in addition again snap device, can in limited space, still can reach effective fastening effect, and then can effectively reduce the height of insulating body 10, make electric connector meet the requirement of slimming.
In addition, can more meet the slimming requirement of electric connector, shown in Fig. 5, be the decomposing schematic representation of terminal module the second enforcement aspect of the present invention.As shown in the figure, terminal module 20 of the present invention is except including the first metal end the 211 and second metal terminal 212, and its holder 22 also includes one first holder 221 and one second holder 222.Its first holder 221 is fixed those the first metal end 211 in injection molding mode; The second holder 222 is fixed those second metal terminals 212 with injection molding side, and guiding block 24 is located at the arranged on left and right sides of the second holder 222.
And the orientation along the first metal end 211 is also provided with a location hole 2211 on the first holder 221, its location hole 2211 is to run through the first holder 221, and the first metal end 211 of part is exposed in location hole 2211.
And the second holder 222 also convexes with a location division 2221 towards the first holder 221 directions, its location division 2221 is to extend along the orientation of the second metal terminal 212, and corresponding with the location hole 2211 of the first holder 221, and 2221 tops, location division also have 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 combination, to 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 that each is exposed in location hole 2211 embeds in each corresponding groove 2222, 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 are to take shape on the first metal end the 211 and second metal terminal 212 in injection molding mode respectively, therefore, can 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 that overlap with thickness, that is utilize location division 2221 and location hole 2211 to reach the effect that thickness overlaps, therefore can effectively reduce the thickness of the first holder 221 and the second holder 222, the thickness of its integral terminal module 20 is reduced, relative also can make the reduction in bulk of insulating body 10, and then can make whole electric connector more meet the requirement of slimming.
Although technology contents of the present invention is described as above with preferred embodiment; so it is not in order to limit the present invention; those skilled in the art are not departing from spirit of the present invention a little change and the retouching done; all should be covered by category of the present invention, so the content that protection scope of the present invention ought define depending on the claim scope of application is as the criterion.
