Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is extending type combined optical and electrical connector structural representation of the present invention; Fig. 2 is extending type combined optical and electrical connector of the present invention guiding post holes and structure of mounting hole schematic diagram.
Refer to Fig. 1 and Fig. 2, extending type combined optical and electrical connector provided by the invention comprises matrix 8, wherein, one end face of described matrix 8 is smooth flat 2 and is provided with guidepost 1, described guidepost 1 is perpendicular with smooth flat 2, described matrix 8 is provided with guiding post holes 805, and for the mounting hole of fixing electric contact piece and optical collimator assembly, described electric contact piece is located in mounting hole by elastomeric element, be provided with shell 11 outside described matrix 8, described matrix 8 is fixedly linked with shell 11 by middle cover 15, second spring 12 and lock sleeve 14.
Extending type combined optical and electrical connector provided by the invention, described mounting hole comprises the first mounting hole 801 and the second mounting hole 802 for fixing electric contact piece, and for the 3rd mounting hole 803 of fixed light collimator assembly and the 4th mounting hole 804.During two connector docking, guidepost 1 inserts guiding post holes 805, realizes the aligning of electric contact piece first mounting hole 801 and the second mounting hole 802, optical collimator assembly the 3rd mounting hole 803 and the 4th mounting hole 804.
As shown in Figure 1, to be arranged on by the optical collimator assembly be made up of lens 19, glass bushing 20, optical fiber contact pins 18, Plug pin patch bay 17 and contact pin cover for seat 16 in optical collimator assembly the 3rd mounting hole 803 on matrix 8 and the 4th mounting hole 804 by debugging, light beam is vertical with smooth flat 2.By by electric jack 3(or electric mortiser pin 21), insulation sleeve 4(electric mortiser pin also needs insulating mat 22), electric jack (pin) assembly that forms of insulation cover for seat 6 can be other flexible members by the first spring 7(), pressing plate 9 and screw 10 be arranged in electric contact piece first mounting hole 801 and the second mounting hole 802, is in relative unmanaged flexibility state.Middle cover 15 is connected with matrix 8 by screw thread, after then overlapping the second spring 12, packing ring 13 on middle cover 15, through shell 11, lock sleeve 14 is spun on middle cover 15 and forms locking mechanism.
During two connector docking, guidepost 1 inserts the guiding post holes 805 of another connector, and now electric mortiser pin 21 inserts in the electric jack 3 of another connector, as shown in Figure 4.The shell 11 of two connectors is by screwing locking, and as shown in Figure 5, two connector smooth flat 2 are bonded to each other, and as shown in Fig. 3, Fig. 5, now the collimator assembly of two connectors on the same axis, aims at logical light.Because electric mortiser needle assemblies and electric jack assembly are in relative unmanaged flexibility state, can be movable in certain space, bonded to each other because this reducing smooth flat 2, collimator assembly impact on the same axis, thus ensure that optical property.The seal 5 be arranged on matrix 8 is bonded to each other compacted, realizes the butt-end packing of connector.
