Flexible recess 31C is formed between few elastic fin a 31B, elastic fin 31B, in order to close when other side's connector is inserted
When sealing gap between the two, the elastic buffer of waterproof jacket 31.
The another way that waterproof jacket 31 may be set is, as shown in figure 3, being fixed with inlay on step-like installation portion 32
33, waterproof jacket 31 is arranged on installation portion 32 molds waterproof construction by inlay 33 in insert molding machine, waterproof jacket 31
Front end face 31A forward ends extend, beyond the end face of the antetheca 12 of interface 11, elastic fin 31B are formed, in the antetheca 12 of interface 11
Sealing is realized, certainly, in 31 insert-molding of waterproof jacket, the front end face 31A of waterproof jacket 31 can be to the direction of antetheca 12 of interface 11
Extension, waterproof jacket 31 wraps up the antetheca of interface 11 and reaches the sealing effectiveness of antetheca 12.
Wherein, location division 25 may include front end location division 25A and rear alignment portion 25B, rear alignment portion 25B section shape
Shape is identical substantially with the cross sectional shape of shell 10, and when terminal member 20 is configured in shell 10, rear alignment portion 25B is fixed
In the one end of shell 10 away from interface 11, close to the terminal position of shell 10.
In order that obtaining terminal member 20 is configured in consolidating in shell 10, as shown in figure 3, the inner face of shell 10 can be radially
It is extended with annular flange 14, annular flange 14 is by 10 points of first connecting portions 15 and second connecting portion 16 for connection of shell, first
The space that connecting portion 15 has is grafting space 30, and the space that second connecting portion 16 has is fixed space 34, rear alignment portion
25B is installed in fixed space 34, is fixed on this terminal member 20 in shell 10, annular flange 14 can increase location division 25
With the contact area of shell 10, so as to improve the firm reliability of terminal member 20, it is ensured that terminal member 20 is remained to after multiple plug
Stable state is enough in, as preferred scheme, the internal diameter of first connecting portion 15 is less than the internal diameter of second connecting portion 16, can enter one
Step improves location division 25 and the contact area of shell 10.
The fixed form of insulating body 21 and shell 10 can be used：Rear alignment portion 25B is fixed on by fixation by glue
In space 34, and/or by being embedded small iron plate 35 in insulating body 21, then by insulating body 21 by way of welding
It is fixed as one with shell 10.
Rear alignment portion 25B lateral length is less than the lateral length of second connecting portion 16, so that in the rear end of shell 10
Sealing space 17 is left, the dispensing in sealing space 17 solidify to form glue part 17, to close the shell 10 away from interface 11
One end, reach the water proof and dust proof effect of the rear end of shell 10.
The structure of first end component 22 and Second terminal part 23 is essentially identical, by taking first end component 22 as an example, such as Fig. 5 institutes
Show, including two ground terminals 50 and several ungrounded terminals 51, the ungrounded terminal 51 of each terminal assemblies 22 and 23
Between two ground terminals 50, wherein ungrounded terminal 51 is again including two power supply terminals 511 and several signal terminals
512, the signal terminal 512 of each terminal assemblies 22 and 23 is located between two power supply terminals 511, as preferred embodiment,
As illustrated, the ungrounded terminal 51 of first end component 22 and Second terminal part 23 is 6, but not limited to this, it is non-to connect
Ground terminal 51 can be more than 6 or less than 6, and the quantity of signal terminal 512 accordingly changes.
The front end of two ground terminals 50 and some ungrounded terminals 51 of first end component 22 and Second terminal part 23
Portion 61 is exposed at the surface of insulating body 21 and turned on for other side's connector contact, and the part in the positioned adjacent portion 25 of leading section 61 is root
Portion 40, medial end portions 62 are embedded in location division 25, and rearward end 63 is used to connect substrate of the configuration in equipment.
Shielding plate 24 is arranged between the first terminal component 22 and Second terminal component 23, and preferred scheme is, the masking
Piece 24 be two panels, respectively positioned at the first terminal component 22 a ground terminal 50 and the Second terminal component 23 it is corresponding
Between ground terminal 50, there is certain horizontal clearance between the power supply terminal 511 adjacent thereto of ground terminal 50.
The structure of shielding plate 24 is as shown in fig. 6, shielding plate 24 is provided with multiple through holes 241, and the structure of formation is substantially
Sheet engraved structure, as shown in figure 4, the medial surface of shielding plate 24 is arranged on the power supply terminal 511 adjacent thereto of ground terminal 50
Between the corresponding position of horizontal clearance at, its horizontal clearance L between adjacent power supply terminal 511 is not less than safe spacing
Value 0.5mm, preferably 0.67mm, thus shielding plate 24 and the whole empty avoidings of power supply terminal 511, prevent power supply terminal 511 and masking
The short circuit of piece 24, reduces burning machine risk.
In order to reduce whole terminal overall impedances, the thickness H of ground terminal 50, power supply terminal 511 and signal terminal 512 is adopted
Made of the highly conductive terminal material for being not less than 0.2mm, preferably 0.25mm；Moreover, in order to reduce source impedance, ground connection can be made
The cross section S1 of terminal 50 and the cross section S2 of power supply terminal 511 area are all higher than the cross section of the signal terminal 512
S3 area, especially, can make widening treatment in the medial end portions 62 of ground terminal 50 and power supply terminal 511.
It is understood that those skilled in the art can also do other changes etc. in spirit of the invention is used in the present invention's
Design, without departing from the technique effect of the present invention.These changes done according to present invention spirit, should all be included in
