[embodiment]
Fig. 1 is to each view that Figure 5 shows that the utility model electric connector 100 first embodiment, and Fig. 5 to Fig. 8 is each view of second embodiment of utility model electric connector 100.
The utility model electric connector 100 comprises the insulating body 1 that is provided with accepting groove 14, is assembled in the terminal 2 in the accepting groove 14, and is located at insulating body 1 metal shell 3 on every side behind the assembling terminal 2.
Insulating body 1 comprises matrix 11 and is positioned at matrix 11 front end hyoplastrons 12, and the horizontal direction that 12 of matrix 11 and hyoplastrons are provided with some perforation hyoplastrons 12 and matrix 11 is the passage 13 that distributes of type linearly, and hyoplastron 12 front ends are provided with the accepting groove 14 of above-below direction extension.Hyoplastron 12 comprises two plugs, 15,16 compositions, and in the middle of two plugs 15,16 and both sides form three fixing districts 17 altogether, and 17 rear portions, fixing district are formed with continuing surface 171.Plug 15 is installed a greater number terminal 2, and plug 16 is installed lesser amt terminal 2, is provided with some passive divider walls 18 in the middle of the matrix 11 of plug 15 correspondences to strengthen the intensity of plug 15.Off-center position, insulating body 1 top is provided with and holds platform 19 and play fixing metal housing 3 and prevent the effect that insulating body 1 misplugs.
Metal shell 3 is folded by metallic plate and forms, and the two ends butt joint forms hollow shelly body, and the docking site forms dentation docking section 30, has increased the density of the interior tie point of unit length on the metal shell 3 depth directions like this, has improved the bond strength of metal shell 3.Metal shell 3 comprises diapire 32 and corresponding roof 31, and the sidewall 33 that is positioned at 31 of diapire 32 and roofs, the pin 331 that diapire 32 punching out and the formation of turning up are connected with sidewall 33, button forms button and holds sheet 332 in sidewall 33 rear ends, the continuing surface 171 in the fixing district 17 on diapire 32 elasticity of extension arms 321 and the insulating body 1 contacts, and cooperates with diapire 32, roof 31 trailing edges of metal shell 3 to realize gripping of insulating body 1.This metal shell 3 is provided with the support slot 311 corresponding with holding platform 19.
More than be the basic structure of the utility model electric connector 100, the utility model provides the interference structure of two kinds of terminals 2 with accepting groove 14, prevents to be contained in the terminal 2 terminal perks in the accepting groove 14.
Among first embodiment, the contact site 21 of terminal 2 is provided with the card thorn 211 that thrusts in the accepting groove 14, please join Fig. 4, and this kind structure can prevent terminal 2 perks.
Among second embodiment, accepting groove 14 is provided with to projecting inward boss 141, interferes with terminal 2 sides of flush state, sees also this kind of Fig. 8 structure and can prevent terminal 2 perks.
These two kinds of structures all can realize the fixing of accepting groove 14 and terminal 2, and the end that prevents terminal 2 is from accepting groove 14 interior perks.
