Embodiment

By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.

See also Fig. 1, the utility model power supply changeover device comprises a switch main body 10 and a plug 20.This switch main body 10 comprises that the plug host body 120 cylindraceous and that roughly is that a housing 110, cylindraceous is installed on the housing 110 is fixed in two body terminal 130 that are column on the plug host body 120.

See also Fig. 2, plug host body 120 has a tube bottom 121 and from the vertically extending barrel of tube bottom 121 peripheries portion 125.Offer two card base draw-in grooves 124 in the barrel portion 125, the swivelling chute 1242 that card base draw-in groove 124 has that a guiding groove 1241 of offering from barrel portion 125 upper surfaces and is connected with guiding groove 1241 bottoms downwards and extends along the circumferencial direction of barrel portion 125.Offer the groove 122 of a fan ring-type on the tube bottom 121, tube bottom 121 extends holding strip 123 in the edge of groove 122 1 ends, and the part of holding strip 123 is stretched out groove 122, and holding strip 123 has a slide guide face 1231 and a catch surface 1232.

See also Fig. 1, Fig. 3, Fig. 4 and Fig. 5, plug 20 comprises a connector assembly 210, two shell fragment terminals 220, a jack shell 240 and an inserting terminal group 250.This jack shell 240 is immobilizated on the connector assembly 210, and this inserting terminal group 250 is installed between jack shell 240 and the connector assembly 210.

Connector assembly 210 bottoms have a bottom 211.Protrude out a retaining that roughly is triangular shape on the lower surface of seat bottom 211 and hold piece 212, this retaining is held piece 212 and is had the retaining inclined-plane 2122 that a wiping face 2121 and that is arcuation roughly is the clinoplain shape and is connected with wiping face 2121.Offer two shell fragment terminal grooves 213 on the connector assembly 210, this shell fragment terminal groove 213 has the hugging 2131 of a fan ring-type and that offer from the diapire of hugging 2131 and connect the bulk end pilot trench 2132 that being of this connector assembly 210 fan ring-type.Connector assembly 210 protrudes out a fixed leg 214 in the end place near shell fragment terminal groove 213.The bottom of connector assembly 210 has two card bases 215 that outwards protrude out.

Shell fragment terminal 220 have a fan ring-type can with inserting terminal group 250 butts compress sheet 221.An end that compresses sheet 221 offers a fixing hole 225, and this fixing hole 225 is set on the fixed leg 214.Compress other end bending extending a curved elastic joint part 222 of sheet 221.What the end of elastic joint part 222 was extended with a fan ring-type replaces sheet 223, replaces the end bending of sheet 223 and extends an elastic supporting part 224, and the end of elastic supporting part 224 is resisted against and compresses on the sheet 221.Elastic joint part 222, replace sheet 223 and elastic supporting part 224 is positioned at hugging 2131.

As mentioned above, the plug 20 of the utility model power supply changeover device at first inserts card base 215 in the guiding groove 1241 when docking with switch main body 10, and at this moment, body terminal 130 stretches into the bottom of bulk end pilot trench 2132; Rotary connector 20 then, card base 215 rotates in the swivelling chute 1242, this moment, body terminal 130 ends were resisted against replacing on the sheet 223 of shell fragment terminal 220, slip over slide guide face 1231 back catch surface 1232 at wiping face 2121 and keep out retaining inclined-plane 2122, thereby can prevent the plug revolution and realize fixing and docking of plug 20 and switch main body 10.With plug when switch main body 10 is taken out, plug 20 is applied opposition, retaining inclined-plane 2122 can rely on the inclined-plane to force resolution effect producing the extruding component with catch surface 1232 corresponding ends and holding strip 123 is depressed holding strip 123 again, thereby catch surface 1232 is no longer kept out retaining inclined-plane 2122, so switch main body 10 cycles also can be with plug 10 taking-ups relatively for plug 10.

As mentioned above, the plug 20 of this power supply changeover device is when assembling on switch main body 10, the elasticity that relies on holding strip 123, wiping face 2121 slip over slide guide face 1231 back catch surface 1232 and keep out retaining inclined-plane 2122 automatically and plug 20 and switch main body 10 are held be fixed together; Plug 20 is applied opposition, and retaining inclined-plane 2122 will be with the depressing with catch surface 1232 corresponding ends of holding strip 123, thereby can take out plug 20 easily.In a word, this power supply changeover device is easy to use, and is difficult for damaging because of misoperation.
