Above, with the buckle 2 stoping each modular plug insulator to disengage in the vertical direction, fixed structure includes the use being arranged on buckle
The first positioning boss 1-1 in the first locating groove 12-1 on corresponding plug insulation module body of the positioning and plug-in mounting in left-right direction
With the second positioning boss 1-2 in the positioning and plug-in mounting the second locating groove 12-2 on corresponding plug insulation module body, the first location
Boss and the second positioning boss line up front two rows respectively, and in each registration boss, adjacent two positioning boss interval is arranged, fixing
Structure also include being arranged on buckle for coordinating with the locking draw-in groove 11-3 retaining on corresponding plug insulation module body, to realize
Buckle and the locking barb 3 of each modular plug insulator anticreep in the lateral direction, locking barb also has multiple.Along front on buckle
Rear is equipped with push pedal 5 to guiding movement, and on buckle, front side in push pedal is provided with and puts in place with corresponding adapter socket grafting at plug
Time with lock anticreep groove 10 retaining on reed 8 on socket and coordinate and realize the anticreep of plug, socket anticreep in the plugging direction
Thorn 9, the front end of push pedal is provided with when push pedal is moved forward and promotes lock spring off-chip swollen and make anticreep hangnail be deviate from by anticreep groove
Pushing part 7, the front end of pushing part be provided with for locking reed inside guiding surface 8-1 gradient adaptive to move forward in push pedal
Time promote the swollen pushing tow inclined-plane 7-1 of lock spring off-chip.It is top-loaded with between push pedal and buckle and forces the pushing part of push pedal away from lock spring
The back-moving spring 4 of sheet, push pedal and buckle are provided with the lead 6 being arranged in back-moving spring.
Plug construction described in above-described embodiment is as shown in Fig. 4～12: plug includes multiple plug mould being stacked up and down
Block 21, during use, one latch assembly 20 can be fixed together multiple modular plug, and each modular plug all includes that plug is exhausted
Edge module 11 and the Plug contact 14 being arranged in plug insulator module, pressing plate 18, tension disc 16 and shielding sheet
13, the upper surface of each modular plug insulator is provided with insulator positioning boss 11-4, lower surface is provided with insulator
Detent 11-8, the most adjacent two modular plug insulators can be by insulator positioning boss and insulator detent
Location grafting realize X-Y two-dimensional directional to each other accurate, reliably position, X-Y two-dimensional directional refer to left and right directions and
Fore-and-aft direction, each modular plug insulator anticreep in the vertical direction is then realized by the buckle of latch assembly, latch assembly
Buckle spiral-lock on the left surface of each modular plug insulator, adjacent two modular plug insulators are provided with across adjacent two
Individual modular plug insulator coordinates the first locating groove 12-1 and the second locating groove 12-2, the positioning boss on buckle at interface
With locking barb and corresponding locating groove positioning and plug-in mounting, thus achieve buckle and each modular plug insulator is fixed together
, on the right flank of each modular plug insulator, spiral-lock has auxiliary buckle 22, and what this auxiliary buckle was same is provided with convex
Platform and locking barb, but it is not provided with push pedal, anticreep hangnail and back-moving spring etc. on it.Modular plug insulator and Plug contact
Locator card is filled by force on the contact locating slot 11-1 that cooperation between part is dependent on modular plug insulator and Plug contact
Cooperation between platform 14-1 realizes location and fixes.Plug contact afterbody passes through to weld to be linked to be to 15 with difference cable differential lines
A piece transmission line, is then fastened on pressing plate and tension disc on modular plug insulator.Between pressing plate and modular plug insulator
Location, the many places hole 18-1 on pressing plate and many places locating dowel 11-5 on modular plug insulator is relied on to be realized by strong dress the most fixed
Position, thus each part is fixed as one.The positioning boss 16-3 on tension disc is relied between tension disc and modular plug insulator
With the fixed station arranged on the positioning step 11-2 arranged on fixing barb 16-2 and modular plug insulator upper surface and lower surface
Rank 11-7 will be fixed to one another and be integrated, and every difference cable is fixed on accurate location by the pressuring line groove 16-4 on tension disc, injection
Glue by leaving over the area bigger than tension disc strike-through mouth at the strike-through mouth back side after tension disc strike-through mouth 16-1, after glue solidification
Modular plug insulator and tension disc are played good fastening effect.It is designed with many places the last the first in shielding chip architecture and fills hangnail
13-3 and the last the second dress hangnail 13-2 structure, the surface of corresponding modular plug insulator is designed with many places the first locating slot 11-
9 and the second locating slot 11-6 structure, shielding sheet relies on the high resiliency support of strong dress hangnail and shielding sheet with plug insulator after fastening
It is firm, reliable that effect ensures that shielding sheet coordinates with insulator.Differential lines pair and shielding sheet structurally form microstrip line transmission mould
Formula, can be effectively ensured the standard-required of differential impedance 100 Ω, effectively reduce the cross talk effects between signal simultaneously, meets height
Speed transmission signal integrity requirement.In figure, 17 represent embedding part, and 13-1 represents shielding sheet encapsulating mouth.
The plug of this differential connector is mainly used between the distance plate between communication apparatus inner panel and plate, between plate and equipment
High speed data transfer, has 100 Ω characteristic impedance requirements, and single set product can provide much 40 pairs of differential signal transmission to want
Ask, the differential signal transmission rate requirement of up to 2.5Gbps can be realized in about 1 meter distance, in military affairs, aviation, boat
My god, communication, industrial automation, the field such as imaging of medical be widely used space.
In other embodiments of the invention: the pushing tow inclined-plane on pushing part can not also set, now the front end face of pushing part can be ball
Face or a vertical facade；Back-moving spring can also is that the extension spring being arranged between push pedal rear end and locking member body；Lead
Can not also set, the corresponding gathering sill installed for back-moving spring now can be set on locking body；Locking member body also may be used
To be block structure or rack-like structure, locking member body can also be fixed on plug by screw or encapsulating form, certainly locks
Part body can also be wholely set with the plug insulator of plug；Certainly in the present invention, the principle of latch assembly can also be generalized to it
In the connector of its type.
