[embodiment]
See also Fig. 1 and Fig. 2, the utility model electric connector 100 mainly comprises insulating body 1, be immobilizated in conducting terminal 2 on the insulating body, be covered in insulating body 1 shielding casing 3, be assembled in insulating body 1 earthing member 4, be welded in the first ground cable 5, the signal cable 6 of earthing member 4 and be welded in the second ground cable 7 of shielding casing 3.
See also Fig. 3 and Fig. 4, the lower surface (not label) that described insulating body 1 has a upper surface 101 and is oppositely arranged with upper surface 101.Described upper surface 101 is concaved with plural groove 103 downwards, is provided with the constriction 104 of fin shape between each groove 103.The both sides of described insulating body 1 are outward extended with respectively fixation wall 106, and the rear end of described fixation wall 106 is provided with the protuberance 105 that projects upwards.After shielding casing 3 was installed on fixation wall 106, shielding casing 3 was outstanding backward than the rear end of insulating body 1, thereby formed cable placement space 107 (ginseng Fig. 4).
Conducting terminal 2 is immobilizated in the insulating body 1, and described conducting terminal 2 comprises that the connecting portion 22 that is contained in corresponding groove 103 reaches from the docking section 21 that connecting portion 22 extends forward, and described conducting terminal 2 mat constrictions 104 make things convenient for welding follow-up and cable.Described conducting terminal 2 comprises two types at least, signal terminal 201 and earth terminal 202.Be provided with two signal terminals 201 between per two earth terminals 202, to form one group of differential pair signal, the signal that is used for reducing between the signal terminal 201 disturbs.Electric connector also comprises signal cable 6, and described signal cable 6 is electrically connected on the signal terminal 201.
Described shielding casing 3 is coated on insulating body 1, disturbs in order to prevent the signal that EMI causes.Described shielding casing 3 comprises shielding casing 31 and the lower shielding casing 32 that cooperatively interacts with upper shielding casing 31.Described upper shielding casing 31 is assembled in insulating body 1 from top to bottom, on this shielding casing 31 comprise one cover first of upper surface 101 cover section 311 and from first cover that section 311 extends back exceed section 312.In the vertical direction exceeds section 312 and is positioned at the first top that covers section 311, this exceed section 312 also be positioned at conducting terminal 2 connecting portion 22 the top and be covered in protuberance 105, simultaneously, this exceeds section 312 and extends back and exceed connecting portion 22.Described lower shielding casing 32 is assembled in insulating body 1 from bottom to top, and this time shielding casing 32 extends back and surpasses the rear end of insulating body 1, thereby forms for cable placement space 107.Forward and backward side and the left and right side at described upper and lower shielding casing two ends are respectively equipped with holding part 313a, 313b, 323a, 323b, thereby the mutual buckle of these holding parts is so that upper and lower shielding casing is immobilizated in fixation wall 106.Article two, the second ground cable 7 is welded in respectively the two ends of shielding casing 3, and is positioned at all signal terminals 201 and earth terminal 202 both sides.
Described earthing member 4 is installed on the rear end of insulating body 1, this earthing member 4 designs for single piece type, it comprises the clinch 42 that support portion 41 and self-supporting section 41 extend forward and be connected with each earth terminal 202, and each clinch 42 lays respectively between the two adjacent constrictions 104 and exceeds constriction 104.The lower surface (not label) that described support portion 41 has a upper surface 411 and is oppositely arranged with upper surface 411.In the present embodiment, described support portion 41 exceeds the rear end of insulating body 1, and is oppositely arranged with lower shielding casing 32.Because support portion 41 is unsettled being arranged in the cable placement space 107, of long duration may the lower surface (not label) of support portion 41 be contacted with lower shielding casing 32 because of the factor of touching.In the present embodiment, described lower surface (not label) is coated with insulating barrier 412, even this insulating barrier 412 is so that earthing member 4 comes in contact also with lower shielding casing 32 can not electrically conduct.Described upper surface 411 (insulating barrier is not set) and clinch 42 can electrically conduct with earth terminal 202.The first ground cable 5 has core 51, and this first ground cable 5 is housed in the corresponding groove 103, and mat constriction 104 makes things convenient for bonding wire.Described core 51 is welded in the clinch 42 of earthing member 4 or the upper surface 411 of support portion 41 (earthing member 4 is between the first ground cable 5 and shielding casing 3).Because support portion 41 and clinch 42 electrically conduct with earth terminal 202, therefore only need to reach the purpose with all earth terminal 202 ground connection in any two clinchs 42 welding the first ground cable 5 that is welded in earth terminal 202.Because earthing member 4 and shielding casing 3 have different ground connection effects, therefore both ground connection is independently separated, help better to prevent that stop signal disturbs.
Exceed section 312 because the protuberance 105 of base portion 10 cooperates, hold the height that causes electric connector 100 to increase owing to the first ground cable 5 of extra soldered on earthing member 4 so that have enough spaces between upper shielding casing 31 and the lower shielding casing 32.Simultaneously, because protuberance 105 and exceed the setting of section 312 so that upper shielding casing 31 does not come in contact with earthing member 4, also is not electrically connected between therefore upper shielding casing 31 and the earthing member 4.The first ground cable 5 is also separated upper shielding casing 31 with signal cable 6 with earthing member 4 simultaneously.
Owing to not having electric connection between shielding casing 3 and the earthing member 4, being welded in second ground cable 7 and the first ground cable 5 difference independent groundings that are welded in earthing member 4 of shielding casing 3.That is, shielding casing 3 and earth terminal 202 be independent groundings respectively, thereby have improved the signal quality of electric connector 100.This place is stated not contact and come in contact and is not also produced electric connection and all can be regarded as insulation.
Fig. 5 to Fig. 7 is the relevant indicators of the second execution mode of the utility model electric connector 100 ', the described insulating body 1 ' blocking part 11 between protuberance 105 that extends back.The lower surface of the support portion 41 of described earthing member 4 (not label) is positioned at upper surface 111 tops of blocking part 11.Because blocking part 11 is insulator, therefore can lower shielding casing 32 be intercepted with earthing member 4 by this blocking part 11 and open, and then avoid between time shielding casing 32 and the earthing member 4 electrical contact occuring.Owing to not being electrically connected (concrete reason is described with the first execution mode) between upper shielding casing 31 and the earthing member 4 yet, therefore, not having electric connection between shielding casing 3 and the earthing member 4.Therefore, be welded in second ground cable 7 and the first ground cable 5 difference independent groundings that are welded in earthing member 4 of shielding casing 3.That is, shielding casing 3 and earth terminal 202 be independent groundings respectively, thereby have improved the signal quality of electric connector 100.
Present embodiment is the utility model better embodiment, and certainly, the utility model also can adopt other real-time modes, gives unnecessary details no longer one by one herein.
