Specific embodiment

Refering to Fig. 1, Fig. 2, Fig. 3, the utility model includes socket 1, plug 2；

The socket 1 is made of jack housing 11, microswitch 12 and female terminal 13, and both sides are lateral in jack housing 11 It is set equipped with hanger pin 112, longitudinal direction there are two socket end sub-aperture and a microswitch hole 111；

The female terminal 13 is set in socket end sub-aperture, and microswitch 12 is set in microswitch hole 111；

Refering to Fig. 3, Fig. 5, one end is equipped with electrode 123 on the microswitch 12, and the other end is equipped with switch contact 122 and opens Close shrapnel 121；

Refering to Fig. 1, Fig. 2, Fig. 3, the plug 2 is made of plug body 21, plug terminal 23 and plug rocking bar 24, is inserted Plug end sub-aperture and a protrusion means 22 there are two both sides are transversely provided with axis pin 213 on head shell 21, longitudinal direction is set, plug rocking bar 24 are arranged with arc groove 241 and rocking bar axis hole 243 for both sides；

Refering to Fig. 1, Fig. 6, the plug rocking bar 24 is across 21 both sides of plug body, and the rocking bar axis hole of plug rocking bar 24 243 is hinged with the axis pin 213 of plug body 21, and plug terminal 23 is set in plug end sub-aperture；

Refering to Fig. 2, Fig. 4, the protrusion means 22 are equipped with the depression for being oriented to groove 212 for periphery, and triangle is equipped in depression The convex block 211 of shape；

Refering to Fig. 1~Fig. 6, the socket 1 and 2 grafting of plug, female terminal 13 and 23 grafting of plug terminal, socket 1 212 grafting of guiding groove of microswitch 12 and plug 2, and the switch shrapnel 121 of microswitch 12 and protrusion means 22 is convex Block 211 touches, and the arc groove 241 of plug rocking bar 24 and the hanger pin 112 of jack housing 11 are sealed.

The course of work of the utility model

Refering to Fig. 1~Fig. 7, when socket 1 and 2 grafting of plug, female terminal 13 contacts first with plug terminal 23, when slotting Seat terminal 13 and 23 further grafting of plug terminal, the microswitch 12 of socket 1 and 212 grafting of guiding groove of plug 2, with slotting The arc groove 241 of head tremor bar 24 is completely sealed with the hanger pin 112 of jack housing 11, at this point, the switch shrapnel of microswitch 12 121 oppress deformation by the convex block 211 of protrusion means 22, and switch shrapnel 121 presses microswitch 12 completely so that microswitch 12 On electrode 123 be connected, microswitch 12 controls female terminal 13 to be connected with the high pressure of plug terminal 23, in plug rocking bar 24 and Jack housing 11 completely it is sealed in the state of realize high pressure connection.This process is socket 1 and the moment of 2 complete interworking of plug in place It opens for electric signal.
