So that the elastic fastening arm 2314' has enough jib-lengths and elastic deformation space.The limited wall 2313' is corresponded to and public affairs
131 outer surface of the male end main wall fitting of electric connector 1 is held, the Position Design of the limited wall 2313' can be conducive to male end electricity
Connector 1 and docking for female end electric connector 2 are spacing, may be such that docking stability is good, mutual rolling is not likely to produce after the completion of docking
It is dynamic.The guiding face 2310' is located at the inner side and top position of the limited wall 2313'.
It refer to shown in Fig. 7 to Fig. 8, the inside bending extensions of the female end fixed feet 232' on the female end metalwork 23' are simultaneously
With corresponding to female end insulator 21' recline circuit substrate side surface formed clasp groove 210' clasps fix.The female end
The female end main wall 231' of metalwork 23', which encloses, to be set and female terminal 22' peripheries (including female terminal weld part 223').First
In embodiment, the female terminal weld part 223' convexedly stretches in mother by female end main wall 231' lower lips through female end main wall 231'
Hold outside main wall 231'.It can actually need to adapt to selection implementation according to female end electric connector 2' appearance and sizes.
In other embodiments, can be designed on the male end electric connector 1 accordingly with it is any one in above-mentioned two embodiment
The structure that elastic buckle 2302 in a coordinates, such as the correspondence position of the male end metalwork 13 in male end electric connector 1 are set
The structures such as the groove (not shown) being buckled with elastic buckle 2302.
The present invention (is specially male end metal by adding metalwork in male end electric connector 1 and 2 periphery of female end electric connector
Part 13 and female end metalwork 23), with realize male end electric connector 1 docked with female end electric connector 2 after shielding, noiseproof feature.
The metalwork 13 in the present invention, 23 structure designs are simple at the same time, and male and female end electric connector 1,2 overall construction intensities are good, metalwork
13rd, 23 thin portion structure design can play good docking guiding and fastener at the same time, can control electric connector combination
In the case where whole height is relatively low, ensures male and female end electric connector 1,2 structural strengths, docking stability and have preferable
Plug feel.
It should be noted that during this law is bright, the male end main wall 131 of the male end metalwork 13 is substantially in cuboid tubulose
(also can be considered cuboid ring-type), the female end main wall 231 of the female end metalwork 23 in above three embodiment are substantially in
Cuboid tubulose (also can be considered cuboid ring-type).Above-described " cuboid tubulose ", " cuboid annular " should be broad sense
Understanding.Because after realizing that male end electric connector 1 is docked with female end electric connector 2, ensure male end
Signal transmission is stablized between son 12 and female terminal 22, and from external interference.Thus, it is only required to realize male end electric connector 1 with
After the completion of female end electric connector 2 docks, the male terminal 12 and female terminal 22 and the extraneous function of shielding that are mutually butted.Namely
Say, 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 male end metalwork 13 and female end metal
The metal shield that part 23 is formed surrounds male terminal 12 and female terminal 22 to realize shielding.Therefore, closed in the present invention
In the understanding of " the cuboid tubulose " of female end metalwork 23 and male end metalwork 13, " cuboid annular " can be by male end metal
The design of part 13 is in " C " shape or " L " shape, and it is in " C " shape or " L " shape that corresponding female end metalwork 23 is corresponded to design.When male end electricity
After the completion of connector 1 is docked with female end electric connector 2, by the male end metalwork 13 of " C " shape or " L " and by " C " shape or the mother of " L "
The metal shield common combination that end metalwork 23 is formed encloses the enclosed loop configuration for setting and being formed in a complete meaning,
Anti-noise function is shielded to realize.In addition, in other variations, the male end metalwork 13 and female end metalwork 23 of any shape, only
Want male end electric connector 1 and female end electric connector 2 to complete after docking, collectively constituted by male end metalwork 13 and female end metalwork 23
Metal shield can enclose the enclosed loop configuration for setting and being formed in complete meaning, should be the present invention design marrow
And protection domain.
In the present invention, " male " " mother " end is not merely to statement accurately, refers in particular to a certain form or a certain implementation
Example.In other words, the present invention in the female end electric connector 2 on female end metalwork 23 can with male end electric connector 1
Male end metalwork 13 is to change place.It can equally realize the technique effect of the present invention.
It should be appreciated that although the present specification is described in terms of embodiments, not each embodiment only includes one
A independent technical solution, this narrating mode of specification is only that those skilled in the art will should say for clarity
As an entirety, the technical solution in the embodiment can also change bright book through appropriate, form those skilled in the art
It is appreciated that other embodiment.
Those listed above is a series of to be described in detail only for feasibility embodiment of the invention specifically
Bright, they simultaneously are not used to limit the scope of the invention, all equivalent implementations made without departing from skill spirit of the present invention
Or change should all be included in the protection scope of the present invention.
