In the best embodiment of the utility model discloses, the high frequency connectors 100 pass through heating again after being completed The high frequency connectors 100 are fixed on the circuit board by mode, the technique for such as using Reflow Soldering (Reflow Soldering) (accompanying drawing does not indicate), there are multiple solder joints (accompanying drawing does not indicate) on the circuit board (accompanying drawing does not indicate), (accompanying drawing is not for the solder joint Sign) on be coated with scolding tin, each first weld part 28 of the multiple the first terminal 21 of the high frequency connectors 100 divides It Dui Wei not be arranged on corresponding each solder joint (accompanying drawing does not indicate), temperature rises to the state of scolding tin melting during welding, The scolding tin fills the composition surface of the multiple first weld part 28 and the multiple solder joint (accompanying drawing does not indicate), at a temperature for the treatment of Make the scolding tin that the multiple first weld part 28 of the high frequency connectors 100 is fixed on into the circuit board (accompanying drawing after drop Do not indicate) each solder joint (accompanying drawing does not indicate) and be electrically connected to each other；Due to the high frequency connection during heating The bulk temperature of device 100 is also with rising, each contact arm 41 and the multiple first ground terminal 212 of the metallic plate 4 The contact with each other scolding tin on surface of each first fixed part 29 formed and molten condition and engage each other, make the metallic plate 4 to A few contact arm 41 is welded in first fixed part 29 of first ground terminal 212 of the first end subgroup 2, treats cold But after each contact arm 41 of the metallic plate 4 and each first fixed part 29 of first ground terminal 212 by Scolding tin is welded and fixed mutually and lifts electric connection characteristic, therefore the metallic plate 4 is connect by first in the first end subgroup 2 Ground terminal 212 and first insulating part 22 and be fixed in a positioning of the insulation shell 1；By the mistake for being heated to cooling Journey is completed the high frequency connectors 100 being fixed on the circuit board (accompanying drawing does not indicate) simultaneously, and by the multiple contact Arm 41 is welded in each first ground terminal 212, effectively simplifies processing step, improving production efficiency.

In the best embodiment of the utility model discloses, the multiple first ground terminal 212 of the first end subgroup 2 Each first fixed part 29 contact and be electrically connected with the multiple contact arm 41 of the metallic plate 4 respectively, it is described more Individual contact arm 41 provides an elastic force in each first ground terminal 212, and it is anti-that the multiple first ground terminal 212 also provides one Active force forms one in each contact arm 41, the surface that each first ground terminal 212 contacts with each contact arm 41 Contact surface, but the electric connection effect that brought into physical contact is provided can be because described contact surface evenness inequality, or contact Angular deviation, cause contact area difference in size and have different impedances, in addition have loose contact situation exist, in order to gram Take this problem and lift earthing effect and stability, the multiple first ground terminal 212 is with the multiple metallic plate 4 in group Last layer scolding tin is plated before dress respectively, wherein the technique for plating scolding tin is not limited to electroplate, is deposited or the methods of sputter (spatter), The mistake heated again together with when the multiple first ground terminal 212 is assembled and contacted with each other with the multiple contact arm 41 Journey, it is described by being filled in after the scolding tin melting between the multiple first ground terminal 212 and the multiple contact arm 41 Surface is contacted, the multiple first ground terminal 212 is connected with the multiple contact arm 41 by the scolding tin after cooling, is had Effect lifting is electrically connected with characteristic, excludes the doubt of loose contact.

Compared to prior art, multiple terminals described in the utility model are arranged as a row, the multiple terminal is buried Incidence, because each terminal fixing part is contained in the groove or the impedance adjustment hole, makes each institute for the insulating part State terminal fixing part can partial denudation in the upper surface and lower surface of the insulating part, make each terminal fixing part in part It can directly be contacted with air, because the dielectric coefficient of air is less than the dielectric coefficient of the insulating part, have the multiple terminal There is preferable high frequency characteristics, its characteristic impedance and cross-talk can be effectively improved, the high frequency connectors transmission high frequency can be avoided Interference problem during signal, promotion signal efficiency of transmission.

By detailed description above, those skilled in the art can be made to understand that the utility model may achieve object defined above really, it is real The regulation of Patent Law is met, whence proposes patent application.It is described above, preferred embodiment only of the present utility model, when The scope of the utility model implementation can not be limited with this；It is therefore all according to the utility model claims and utility model specification content The simple equivalent changes and modifications made, all should still it belong in the range of the utility model patent covers.
