Description
[technical field]
The present invention relates to a kind of electric connector, refer to especially a kind ofly can transmit the interactive numerical digit video clip of digital signals and analog signal (Digital Visual Interface, DVI) type electric connector simultaneously.
[background technology]
Along with the development of telecommunications industry, a kind of interactive numerical digit video clip type electric connector that can transmit digital signals and analog signal simultaneously arises at the historic moment.Relevant existing patent application such as United States Patent (USP) the 5th, 558,542,5,387,114,5,580, the 283 and the 5th, 344, cases such as No. 372.Seeing also Fig. 1 is the 5th, 558, No. 542 patent cases, conducting terminal of the electric connector 8 that it disclosed 81 and insulation division 82 one ejection formations, and insulation division 82 is stacked mutually to be fastened in the group-connecting groove of electric connector 8.Wherein 821 of the end faces of the butt end 811 of conducting terminal 81 and insulation division 82 are provided with cantilever portion 812, this butt end 811 is installed with in the longitudinal accepting hole 83 of electric connector 8 with cantilever portion 812, because butt end 811 is longer with the length summation of cantilever portion 812, and lack the structure that effective fixing is located this cantilever portion 812 in the corresponding accepting hole 83, so very easily cause terminal butt end 811 in accepting hole 83, can not accurately locate and depart from former location, and conducting terminal 81 is bigger to relay with the butt joint terminal (not shown) that docks electric connector, in docking operation, also cause easily conducting terminal 81 at cantilever portion 812 places because of stressed improper take place the bending metaboly, cause the butt joint terminal accurately not dock along center line, and influence effective transmission of telecommunication with the butt end 811 of conducting terminal 81.In addition, in the several rows of independent group of group-connecting groove of going into electric connector 8 of the insulation division of existing electric connector 8 82, then by the mutual snap fit of holding part on it.But it is comparatively loaded down with trivial details that this kind organized the mode of going into separately with several insulation divisions, is not suitable for the automation assembling.Moreover, the terminal of this kind transportation simulator signal, because electromagnetic interference more easily takes place each other, thus the electromagnetic interference guiding ground connection that produces between the terminal of earth element with the transportation simulator signal need be set, thus guarantee the stable transfer of telecommunication.
[summary of the invention]
The object of the invention is to provide a kind of electric connector, stressed improper and phenomenons such as bending distortion when it can effectively prevent the offset in terminal when assembling and butt joint, and can prevent effectively that terminal from upspringing and depart from the phenomenon of former location.
For achieving the above object, the present invention adopts following technical scheme: electric connector includes insulating body, the terminal module, holder, shielding casing, members such as fastener and ground connection lamellar body, wherein, insulating body is a longitudinal, be provided with interface and plug surface, and run through interface and plug surface and offer the terminal accommodation holes that plurality of rows is ladder-like arranged, accepting hole has two clamping parts that are crisscross arranged, can borrow the butt end with the terminal of insulation division one ejection formation to be contained in the accepting hole, and the holding parts that terminal is connected in the butt end just can be clamped and fastened between the clamping part that is crisscross arranged in the accepting hole, and the terminal butt end can be immobilizated in the terminal accommodation holes along the center line of accepting hole.
According to above-mentioned principal character, the terminal module that is installed with in second area is divided into upper and lower two rows, on arrange terminal the insulation division insulation minister of row's terminal down, thereby long terminal cantilever is coated and fixed, upspring than the cantilever of length to prevent row's terminal.
According to above-mentioned principal character, be provided with the ground connection lamellar body between the terminal of the transportation simulator signal of electric connector second area, can organize in the electric connector insulating body, connecting, conduct ground connection thereby the electromagnetism noise disturbed with the ground sheet that dock electric connector.
Compared with prior art, the invention has the advantages that connector terminals can be in the accepting hole of insulating body accurate location, and can be effectively with noise ground connection.
