[utility model content]
The purpose of this utility model is to provide a kind of electric connector clamping close device, and the chucking power after can increasing plug and electric connector docking realizes firm butt joint effect, guarantees the telecommunication steady signal transmission; Guarantee product when butt joint stress equalization simultaneously, reach the injury-free effect of protection product, and then prolong product useful life, can also save and manufacture cost.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of electric connector clamping close device, comprise an insulating body, a metal shell and an electric terminal group, this metal shell is coated on the insulating body, this electric terminal group is inserted and is installed in the terminal storage tank that this insulating body establishes, it is characterized in that: the upper surface of this metal shell is provided with a plurality of shell fragments, and is provided with a plurality of holding pieces in other sides of metal shell.
Described electric connector clamping close device is characterized in that: be provided with a plurality of holding pieces in the bottom surface of this metal shell.
Described electric connector clamping close device is characterized in that: the two side walls of this metal shell is provided with a plurality of holding pieces.
Described electric connector clamping close device is characterized in that: the bottom surface of this metal shell and two side walls are equipped with a plurality of holding pieces.
Described electric connector clamping close device, it is characterized in that: this insulating body both sides correspondence is provided with the groove of an export-oriented opening, be provided with a buckle slot along beneath trenches, this metal shell two side correspondence respectively is provided with a fixed block, and this fixed block is the buckle slot location that is snapped in these insulating body both sides; Respectively be provided with a spacer that bends along this metal shell two side root edge, this spacer is inserted in this insulating body groove, can reach the effect that stops insulating body to teetertotter.
Of the present utility modelly focus on the metal shell bottom surface or two sides have additional a plurality of holding pieces, the firm clamping banjo of the shell fragment interfere together of these holding pieces and metal shell upper surface, stress equalization about when having guaranteed the banjo plug, also strengthened simultaneously the contact engaging and separating force between plug and the electric connector, thereby make not easy damaged and increasing the service life of product, also utilize the steadiness after docking to strengthen the butt joint effect better, make the telecommunication output signal more stable.

[embodiment]
See also Fig. 1 to shown in Figure 3, the preferred embodiment of the utility model electric connector clamping close device is-the Mini-USB electric connector, and this electric connector 100 comprises members such as metal shell 10, insulating body 20 and electric terminal group 30, wherein:
Insulating body 20 is the plastics punch forming, which is provided with several terminals storage tank 23, and power supply property terminal group 30 is correspondingly inserted; Respectively there is a reference column 211 at 21 two ends, bottom surface, and these reference columns 211 are to be convenient to product orientation on pcb board; Insulating body both sides 22 correspondences are provided with the groove 222 of an export-oriented opening, are provided with a buckle slot 221 along groove 222 belows, and these buckle slots 221 are the positioning design for preventing that the insulating body displacement from being done.
Metal shell 10 is with the moulding of sheet metal integrated punching, this metal shell 10 is coated on the insulating body 20, be provided with first shell fragment 131 in the middle of its upper surface 13, the both sides that are positioned at first shell fragment 131 respectively are provided with second shell fragment 132, and these shell fragments all can play the effect of firm clamping plug when connector docks; Extend back a bent removable cover 133 along upper surface 13, this cover plate 133 is inserted metal shell 10 rear enclosed posting ports 15 for insulating body 20 and is reached screen effect.
Metal shell 10 two sides 12 are near the corresponding fixed block 122 that is provided with in posting port 15 places, and these fixed blocks 122 are that cooperation is snapped in the buckle slot 221 of insulating body both sides and produces locating effect; 12 root edges are respectively equipped with the welding foot 123 of excurve folding along the two side, in other in opposite directions the spacer 121 of past inner bending that is provided with of welding foot 123, these spacers 121 can be inserted in the groove 222 of insulating body 20, can stop insulating body 20 to produce up and down and rock.
Metal shell 10 bottom surfaces 11 are the panel of a convex shape, this panel is provided with a holding piece 111 at least, these holding pieces 111 form common firm clamping banjo with first shell fragment 131, second shell fragment 132 of upper surface 13, so design not only can strengthen the contact engaging and separating force of banjo, thereby reach more firm combination, realize better butt joint effect, therefore exportable stabilization signal; When plug inserts, can make upper and lower stress equalization simultaneously, reach not easy damaged of protection product, also can prolong the life-span that product uses thus.The position of setting up of these holding pieces 111 can be decided according to the matching mechanism demand of connector, can be located on metal shell 10 two sides 12, or on metal shell 10 bottom surfaces 11 and two side 12 these holding pieces 111 is set all simultaneously.
This electric connector 100 combines like this: 30 insertions of electric terminal group are installed in the terminal storage tank 23 of insulating body 20, subsequently the posting port 15 of insulating body 20 from metal shell 10 injected, fixed block 122 by metal shell 10 two sides 12 cooperates the interference front and back not to be subjected to displacement with the buckle slot 221 of insulating body 20, utilize the spacer 121 of metal shell 10 bottoms to combine simultaneously and reach the effect that prevents that insulating body 20 from teetertottering with the groove 222 of insulating body 20, cover metal shell 10 cover plates 133 at last, thereby reach the shielding effect; Form an electric connector clamping close device thus.
Have additional a plurality of holding pieces 111 on the bottom surface that focuses on this metal shell 10 11 of the utility model electric connector clamping close device or the two side 12, or set up a plurality of holding pieces 111 simultaneously on bottom surface of metal shell 10 11 and the two side 12, set first shell fragment 131, second shell fragment, 132 common clamping banjos on these holding pieces 111 and metal shell 10 upper surfaces 13, thereby this design not only helps increasing contact engaging and separating force, make butt joint more firm, effect is better, and signal output is more stable; And, make the upper and lower stress equalization of product in when butt joint, therefore, it is impaired to protect product to be difficult for, thereby prolongs product useful life.
