Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As illustrated in fig. 1 and 2, a kind of electric connector socket of automatic detection protective cover open mode comprises torsion spring installation shaft 1, socket 2, guard shield 3, cover cap 4, shaft end ring 5, travel switch 6, the first straight pin 7, protective cover 8, torsion spring 9, the second straight pin 10, handle assembly and rocker arm shaft 11.The two ends of torsion spring installation shaft 1 are all connected with the housing 2-1 bearing of socket 2, and the housing 2-1 of one end and socket is by circlip for shaft 14 axial location, and other end cover has guard shield 3; One end of guard shield 3 and the housing of socket are fixed, and the other end is provided with cover cap 4; Shaft end ring 5 is arranged on the lateral surface of cover cap 4, and sunk screw 15 passes shaft end ring 5 and cover cap 4, and is connected with the end thread of torsion spring installation shaft 1.
As shown in Figure 3, the bottom of guard shield 3 offers notch, and the top of travel switch 6 embeds in notch, the contact 6-1 of travel switch and the Cylindrical Surfaces Contact of the first straight pin 7; The first straight pin 7 is fixed on the end of torsion spring installation shaft 1; Travel switch 6 is fixed with the housing 2-1 of socket.
As shown in figs. 1 and 4, one end of protective cover 8 is provided with two hold-down arm 8-1, and the other end is fixedly installed two roller 8-2, and two roller 8-2 are symmetricly set on the both sides of protective cover 8; Two hold-down arm 8-1 are all nested with in torsion spring installation shaft 1, and hold-down arm and torsion spring installation shaft 1 are fixing by the second straight pin 10.Torsion spring 9 is nested with in torsion spring installation shaft 1, and is arranged between two hold-down arm 8-1 of protective cover, and the housing 2-1 of one end and socket fixes, and the other end and protective cover 8 are fixing.
As shown in Fig. 1 and 5, handle assembly comprises handle 12 and handgrip 13; The two ends of handle 12 are fixed with one end of a handgrip 13 respectively, and kink is on a rocker arm shaft 11 respectively for the other end of two handgrips 13, and two rocker arm shafts 11 are all fixed with the housing 2-1 of socket.The top of two handgrips 13 all offers chute 13-1, and two roller 8-2 of protective cover embed respectively in the chute of corresponding handgrip.
This detects the operation principle of the electric connector socket of protective cover open mode automatically:
While leaving behind handle 12, the roller 8-2 of protective cover skids off from the chute 13-1 of handgrip, protective cover 8 is opened, the thrust of the contact 6-1 of the first straight pin 7 to travel switch discharges, contact 6-1 ejects, and a pair of auxiliary contact closure of often opening of travel switch 6, carries out signal output, corresponding warning device can be worked, and plays the effect of warning and finding in advance manual operation.The roller 8-2 of protective cover reduces that protective cover 8 is opened or frictional force when closed and between handgrip 13.
