[embodiment]
Fig. 1 extremely electric connector 100 shown in Figure 2 is the electric connector 100 of the utility model first execution mode.See also Fig. 1 and shown in Figure 2, the utility model electric connector 100 is used for matching with butt connector (not shown).This electric connector 100 comprises an insulating body 2, is mounted to two indicating devices 4, signal processing module 6 and the shielding casing 8 of insulating body 2.
See also Fig. 1 and shown in Figure 2, insulating body 2 comprises an interface 21, the rear end face 22 parallel with interface 21, from interface 21 22 two sidewalls 23 and roofs 24 that extend to back end, two sidewalls 23 and a roof 24 surround a butt joint space 25, and this butt joint space 25 is used to accommodate butt connector (not shown).Roof 24 offers in its both sides from interface 21 22 two flutings 27 that extend to back end, and each is slotted and 27 comprises two medial surfaces 271 and the inner bottom surface 272 vertical with medial surface 271, one of them medial surface 271 be provided with a projection 28.
See also shown in Figure 2ly, each indicating device 4 is monomer bipolarity dual-colored LED, and monomer bipolarity dual-colored LED structure is two different colours and opposite polarity led module parallel connection.Indicating device 4 comprises luminous element 41 and two pins 42 that are connected with luminous element 41.Pin 42 comprises the main part 421 of self-luminous body 41 extensions, the square weld part 422 that autonomous body 421 extends, the main part of one of them pin 42 is being provided with a kink 423 with luminous element 41 junctions, this kink 423 is towards its adjacent leads 42 bendings, and kink 423 matches with the projection 28 of insulating body 2 in order to determine the mounting means of indicating device 4.
See also shown in Figure 2ly, signal processing module 6 comprises an a pair of connecting terminal group 61 and a sub-circuit board 62, and this butt joint terminal group 61 is mounted in the butt joint space 25 to electrically connect with butt connector (not shown).Sub-circuit board 62 is provided with electronic component 621 and conductive path 622, and the weld part 422 of the pin 42 of indicating device is soldered to conductive path 622.
When making this electric connector 100, signal processing module 6 is mounted to insulating body 2 from rear end face 22, butt joint terminal group 61 extends in the butt joint space 25.Indicating device 4 is mounted in the fluting 27, and the kink 423 of pin 42 and fluting 27 interior projections 28 match.The weld part 422 of pin 42 is soldered to the conductive path 622 of sub-circuit board 62.At last shielding casing 8 is covered on insulating body 2 and the signal processing module 6.
