[detailed description of the invention]

In order to enable further to disclose feature and the technology contents of this utility model, refer to the detailed description below in connection with this utility model and accompanying drawing, but institute's accompanying drawings only provides reference and use is described, is not used for this utility model person of being any limitation as.

Refer to Fig. 1, Fig. 2 and Fig. 3, be the respectively three-dimensional exploded view of this utility model first embodiment, three-dimensional combination figure and cross-sectional end view. This utility model provides a kind of multimedia connector structure, including insulating body 1,1 first housing 2 and one second housing 3; Wherein: this insulating body 1 can be the multimedia connector meeting HDMI specification, mainly comprise a tongue 10 and the plural terminals 11 of being located on this tongue 10 surface is constituted, this tongue 10 has first surface 100 and a second surface 101, and described first and second surface 100,101 is all respectively configured (as shown in Figure 3) for above-mentioned terminal 11. This utility model for embodiment in, owing to this insulating body 1 meets HDMI specification, therefore the width of this first surface 100 is more than the width of this second surface 101.

This first housing 2 can be made for metal material, and it is coated on outside above-mentioned insulating body 1, and this first housing 2 front end is surrounded on outside the tongue 10 of this insulating body 1, to form a socket 20 in this first housing 2 front end and between this tongue 10, and namely this tongue 10 is placed in the socket 20 of this first housing 2, and on this first housing 2 front end, it is provided with at least one of this socket 20 supports shell fragment 200; Separately, this first housing 2 rear end then constitutes a covering portion 21, and this covering portion 21 further combined with outside this insulating body 1, and can downwardly extend plural number pin 210 outside this first housing 2. As it is shown on figure 3, this utility model for embodiment in, this insulating body 1 is that setting is located on a circuit board 4, makes tongue 10 and this perpendicular setting of circuit board 4 of this insulating body 1; Further, this insulating body 1 can be provided with a pedestal 12 in the side of the first housing 2 adjacent circuit plate 4, this pedestal 12 is expose to outside the covering portion 21 of this first housing 2, and make the leading edge 120 of this pedestal 12 be resisted against below socket 20, and each terminal 11 end of this insulating body 1 is gone out by this pedestal 12 bottom surface projection, and locating dowel 121 can be equipped with in this pedestal 12 bottom surface, to weld further or to be fixed on circuit board 4.

See also again shown in Fig. 1 to Fig. 3, this utility model mainly lies in said first shell 1 and is externally provided with this second housing 3, this second housing 3 also can be made for metal material, to be at least coated on outside the first housing 1 front end, namely outside relative to socket 20, and the first cladding plate 30 that two intervals are relative can be comprised, and it is connected to 2 second cladding plates 31 between this 2 first cladding plate 30, 32, wherein the first cladding plate 30 is to should the system of shell fragment 200 place that support of the first housing 2 be provided with one-body molded and outwards at least one shielding portion 300 heaving shape, with cover cap in supporting outside shell fragment 200 and promoting the effect preventing electromagnetic interference (EMI). and this utility model for embodiment in, this first housing 2 more can be equipped with plural number fixture block 211 in covering portion 21, and it is provided with corresponding plural hole clipping 301 in the first cladding plate 30 that this second housing 3 is corresponding, it is snapped on fixture block 211 for hole clipping 301 and makes the second housing 3 consolidate is incorporated on the first housing 2.

In addition, as shown in Figures 3 and 4, this utility model also can be folded upward at a support division 320 further in position on the second cladding plate 32 of lower section, this support division 320 is abut socket 20 outside wall surface to the first housing 2 after bending, the position the second cladding plate 32 in lower section then supports and is affixed on described circuit board 4, uses this electric connector of support. Again, for ease of increasing earthing effect, institute's rheme the second cladding plate in lower section also can bend a grounding leg 321 32 times further, to be solidly plugged on described circuit board 4 as ground connection person.

Furthermore, as it is shown in figure 5, in another embodiment of this utility model, this insulating body 1 also can lie low on described circuit board 4, make the tongue 10 of this insulating body 1 parallel setting with this circuit board 4.

Therefore the contexture of above, this utility model multimedia connector structure can be obtained.
