[embodiment]
See also shown in Figure 3ly, the utility model micro coaxial cable connector assembly 1 comprises some electric connectors 10, cable 20, earthing member 30 and insulation lid 40, locates to be equipped with a ground plate 50 in the craft port 12 (ginseng Fig. 6) of this micro coaxial cable connector assembly.
Above-mentioned electric connector 10 is four USBs (Universal Serial Bus, USB) connectors in the present embodiment.Because this electric connector 10 is identical with the existing structure that background technology is partly described, be not described in detail herein.
The cable 20 that links to each other with above-mentioned electric connector 10 comprises some leads 201, be coated on the outer external insulation skin 203 of this lead 201 and be arranged on metal shielding layer (its derivation line label is 202) between above-mentioned lead 201 and the external insulation skin 203.The lead that is used for transmission signal 201 of cable 20 electrically connects with the conducting terminal (not shown) of above-mentioned electric connector 10, the part of then drawing the metal shielding layer of cable 20 derives line 202 and is welded on above-mentioned electric connector 10 shielding casings 101, this connected mode also with background technology in narrated identical, also no longer describe in detail herein.
Earthing member 30 is to be made by the metallic conduction material, is the column configuration, is provided with screwed hole within it.This earthing member 30 is to inlay to be arranged in the lid 40, and in electric connector 10 orientations, be positioned at electric connector 10 sides, the number of this earthing member 30 is three in the present embodiment, one of them is between middle two electric connectors 10, two other is positioned at 10 liang of relative outsides of four electric connectors, and above-mentioned earthing member 30 all is that next-door neighbour's lid 40 front end faces 41 are provided with.
In the present embodiment, from the shielding layer of cable 20 also respectively extension derive line 202, these derive line 202 ends is to be welded on the earthing member 30 and with its machinery and electrically connect.
Please cooperate and consult Fig. 6, ground plate 50 is long and narrow tabular configuration, and its size is more bigger than the front end face 41 of insulation lid 40, is mounted on the front end face 41 of insulation lid 40.On ground plate 50, offer the rectangle frame mouth 51 that the interface 11 with the shielding casing 101 of electric connector 10 aligns, the craft port 12 of electric connector 10 is exposed to outside the ground plate.In addition, on ground plate 50, also offer some through holes (not shown) that can supply bolt 31 (being screw in the present embodiment) to pass.
Some bolts 31 be pass behind the above-mentioned through hole of ground plate 50 with earthing member 30 in establish screwed hole and be screwed, like this ground plate 50 and micro coaxial cable connector assembly 1 are reliably locked.At this moment, the interface 11 of the shielding casing 101 of above-mentioned electric connector 10 just is resisted against on the ground plate 50, the shielding layer of cable 20 welds with earthing member 30 mutually by deriving line 202, and earthing member 30 locks and connects mutually with ground plate 50 simultaneously, thus the path that electrically conducts of formation and ground plate 50.
After the micro coaxial cable connector assembly 1 and the assembling of ground plate 50 were finished, ground plate 50 was grounded function by being assembled on the computer housing panel.Because the existence in the described path that electrically conducts of leading portion, the shielding casing 101 of electric connector 10 and the shielding layer of cable 20 all can be grounded function.
Therefore, even working as the interface 11 of the shielding casing 101 of electric connector 10 breaks away from ground plates 50 surfaces and causes butt unreliable, the shielding layer of cable 20 still can reliably be connected and ground connection with ground plate 50 by earthing member 30, thereby the metal shielding layer that guarantees cable 20 has preferable ground connection performance all the time, and then makes micro coaxial cable connector assembly 1 have good anti electromagnet interference function.
Certainly, the mode that disclosed shielding layer is welded on the shielding casing in the prior art as shown in Figure 2 also can be cancelled in the present embodiment, the derivation line 2 02 of shielding layer be enough to make the shielding layer of cable have the ground connection effect better being connected of earthing member 30 than prior art.The derivation line 202 of shielding layer can be a bare wire, also is coated with insulated hull but terminal exposed lead.In addition, the type of electric connector 10 and quantity also can be implemented the technical solution of the utility model under the situation different with present embodiment, reach same effect.
See also Fig. 4 and shown in Figure 5, its signal be two kinds of situations of second embodiment of the present utility model, the structure of this micro coaxial cable connector assembly 2 and first embodiment are basic identical, and difference is that the earthing member 30 of first embodiment is substituted by the earthing member among second embodiment 302.Earthing member 30 positions of corresponding first embodiment are directly to mold screwed hole 42 backward from its front end face 41 in insulation lid 40 in the present embodiment, for bolt 31 lockings.Please cooperate and consult Fig. 7, earthing member 302 is circular packing rings, is formed with circular hole 306 in the middle of it.Derivation line 202 ends of drawing from the shielding layer of cable 20 pass insulation lid 40 and with earthing member 302 solderless wrapped connection or welding mutually.First kind of situation of present embodiment as shown in Figure 4, the earthing member 302 that is connected with derivation line 202 is to be assembled between the head 304 and ground plate 50 of bolt 31 (being screw in the present embodiment), locking was in the screwed hole 42 of next-door neighbour's front end face 41 of insulation lid 40 after the bar portion 305 of bolt 31 passed the through hole of the circular hole 306 of earthing member 302 and ground plate 50 successively, thereby ground plate 50 reliably was installed on the front end face 41 of insulation lid 40.Second kind of situation of present embodiment as shown in Figure 5, screwed hole 42 front ends next-door neighbour front end face 41 places at insulation lid 40 are formed with depressed part (not label), the earthing member 302 that is connected with derivation line 202 is arranged in the above-mentioned depressed part, the front surface of this earthing member is concordant substantially with lid front end face 41 and connect with ground plate 50, and its circular hole 306 aligns with screwed hole 42.The head 304 of bolt 31 is to be connected on the ground plate 50, the bar portion 305 of bolt 31 passes the through hole of ground plate 50 successively and circular hole 306 backs of earthing member 302 lock in the screwed hole 42 of insulation lid 40, thereby ground plate 50 reliably is installed on the front end face 41 of insulation lid 40.
See also shown in Figure 8, it has shown the 3rd embodiment of the utility model micro coaxial cable connector assembly, the structure of micro coaxial cable connector assembly 1 is basic identical among this micro coaxial cable connector assembly 3 and first embodiment, difference is outwards to convex with installation portion 401 in insulation shell 40 both sides in the present embodiment, is provided with perforation 402 in installation portion 401.Earthing member 32 is nuts, is formed with screwed hole (not label) within it, and derivation line 202 end portion that the shielding layer of cable 20 is drawn are to pass insulation shell 40 backs and earthing member 32 solderless wrapped connection or welding mutually, connected mode and shown in Figure 7 similar.The head 304 of bolt 31 is to be connected on the ground plate 50, and perforation 402 backs of the through hole of ground plate 50 and lid 40 installation portions 401 that insulate are passed successively by ground plate 50 reliably being installed on the front end face 41 of insulation lid 40 with screwing togather of earthing member 32 by the bar portion 305 of bolt 31.
