The docking of device 2 and integral miniaturization design are connect, using the circuit substrate as horizontal plane, the height of the female end base portion 212 is less than
The height of the base portion reinforcing portion 2121, the height of the base portion reinforcing portion 2121 are less than circuit substrate to female end clamping part 2334
Height, the height of the circuit substrate to female end clamping part 2334 is less than the height of female end body part 211.
The present invention, by set female end metalwork 23 and being formed be disposed around the female end main wall 231 of the periphery of female terminal 22 with
Realize female terminal 22 and extraneous function of shielding.It is also, with 231 integrally connected of female end main wall and positioned at both ends by setting
Female end end wall 233 realize and the buckle of male end electric connector 1 is fixed.The whole one piece design of female end metalwork 23 can letter
Change the overall structure stability that processing procedure is conducive to female end electric connector 2 again.
In addition, in other embodiments, the female end metalwork 23 can be designed in two-piece type.It such as will be in above-described embodiment
Female end metalwork 23 female end main wall 231 in some position of each long leg 2311 cut off and cause female end metalwork 23 be in
Two-piece design.23 structure of female end metalwork of two-piece type and the preferred integrated molding fixed form of female end insulator 21, with
Be conducive to the bond strength of female end metalwork 23 and female end insulator 21.
In addition, in other embodiments, an at least extension for each female end end wall 233 at 23 both ends of female end metalwork
2332 can extend towards and engage.So that two female end end walls 233 combination of female end metalwork 23 forms and overlooks female end gold
It is in similar " C " shape open annular structure or " mouth " font (also referred to as rectangle, square) cyclic structure to belong to part 23, so may be used
Further strengthen shielding and anti-noise effect.Again in this embodiment, it should be noted that need to adapt to increase and decrease female end fixed feet 234
Quantity and/or modification female end fixed feet 234 position.
In addition, in other embodiments, it is whole to overlook the female end metalwork 23, the female end master of the female end metalwork 23
Body wall 231 can also be not provided with being rectangle, and can design in the open annular structure similar to " C " shape or only be integrally fixed at
The laminated structure or " L " shape laminated structure of 211 periphery of female end body part, and enclosed by the female end end wall 233 formation
Rectangle or square ring structure arranged on the periphery of female terminal 22 is to realize shielding and anti-noise effect.
Furthermore, it is necessary to explanation, final purpose of the invention is to realize male end electric connector 1 and female end electric connector 2
After docking, it can realize that signal transfers stabilization between male terminal 12 and female terminal 22, and from external interference.Therefore, only
Need after the completion of realizing that male end electric connector 1 is docked with female end electric connector 2, the male terminal 12 and female terminal 22 that are mutually butted and
Extraneous function of shielding.That is, it is only necessary to after the completion of realizing that male end electric connector 1 is docked with female end electric connector 2, by public affairs
The metal shield that end metalwork 13 and female end metalwork 23 are formed is by male terminal 12 and female terminal 22 around the complete meaning of formation
Enclosed cuboid loop configuration in justice is to realize shielding and anti-noise effect.Therefore, on female end metalwork in the present invention
23 and the shape of male end metalwork 13 modification of adaptability can also be made outside above-described embodiment form more embodiments.Only
It need to meet after the completion of male end electric connector 1 is docked with female end electric connector 2,23 groups of male end metalwork 13 and female end metalwork
Into metal shield enclose and formed enclosed in a complete meaning arranged on male terminal 12 and the periphery of female terminal 22 jointly
Loop configuration, you can should be protection scope of the present invention to realize the function of shielding and anti-noise.
It refer to shown in Fig. 7 to Figure 10, be the second embodiment of female end electric connector 2 of the present invention, in second embodiment
2 structure of female end electric connector in first embodiment shown in described female end electric connector 2 " and Fig. 1 to Fig. 6 is essentially identical, only
There is following difference：
One：The female end base portion 212 " of the female end insulator 21 " of the female end electric connector 2 " in second embodiment
Part-structure is different from first embodiment, and the female end base portion 212 " in second embodiment is comprised only positioned at the female end sheet
The part of both sides on 211 " length direction of body portion, the 211 " end positions of female end body part are not provided with similar first embodiment
In the female end base portion 212 structure.
Secondly：The female end metalwork 23 " of the female end electric connector 2 " in second embodiment is in split shape, and second implements
The very little of the 231 " structure design of female end main wall in example, the female end main wall 231 " in second embodiment is by female end
232 " one end of connection wall extends vertically upwards to be formed and corresponded to and be embedded in the 211 " both ends of female end body part.Second embodiment
In, the female end body part 211 " does not have signal shielding, noiseproof feature, and the setting of female end body part 211 " is golden only for providing
Belong to the fixing power of female end metalwork 23 " and female end insulator 21 ".
Thirdly：The centre position of the end wall 2331 " of the female end end wall 233 " in second embodiment is by upside
Recess forms nick shaped flexible part 2335 " to edge downwards, the flexible part 2335 " may be such that female end end wall 233 " in thickness of slab direction to
With better flexibility, female end end wall 233 " is plastically deformed after preventing the insertion of male end electric connector 1.Certainly, the flexibility
Can also there be other embodiment in portion 2335 ", such as be formed by tearing.
It four：In second embodiment, the base portion reinforcing portion 2121 " is made only in 2332 " free end end of extension
Lateral surface position, and the lateral surface position in the lateral surface position of the end wall 2331 " and arc corner 2333 " does not form such as
Base portion reinforcing portion 2121 " described in one embodiment.Such then mode when being conducive to integrally formed positioning and sealing.
It five：In second embodiment, the female end metalwork 23 " is solid with the female end insulator 21 " by being integrally formed
It is fixed.Only only have that the female end main wall 231 " is corresponding to be embedded in the both ends of female end body part 211 " and each extension 2332 "
End position correspondence is embedded in the female end base portion 212 ", the rest part of female end metalwork 23 " in hanging shape without with mother
Insulator 21 " is held to interfere.Compared with prior art, in the present embodiment, ensureing that the arrangement width of female terminal 22 " and contact width are constant
In the case of, reduced entirely to realize by the length and width for the lateral border part for reducing female end insulator 21 " as far as possible
2 " size of female end electric connector, and pass through being realized upwards in the female end end wall 233 " of cantilever-shaped setting for female end metalwork 23 "
With the fastening of male end electric connector 1.In addition two female end end walls 233 " are not directly connected to be integrated, two female end end walls
233 " are independent of each other in independent elastic deformation can occur on thickness of slab direction, and the design for combining flexible part 2335 " is further
Reduce the possibility that female end end wall 233 " is plastically deformed.
In addition, in the present invention, " male " " mother " end is not merely to statement accurately, refers in particular to a certain form or a certain
Embodiment.
