When in 3-phase plug insertion socket, the first three-phase sheet metal, the second three-phase sheet metal are provided with 3-phase plug The first three-phase receiving space 3111, the second three-phase receiving space 3112 and the 3rd three-phase are respectively enterd with the 3rd three-phase sheet metal to receive Hold the inside in space 3113.Due to the length of the first three-phase sheet metal, the second three-phase sheet metal and the 3rd three-phase sheet metal it is identical, It is described during insertion, first the first three-phase sheet metal is contacted with the first three-phase intermediate plate 351, and is clamped by it, first Three-phase sheet metal to the first three-phase intermediate plate 351 applies pressure so that the first three-phase intermediate plate 351 and three-phase slide block 320 are common Slide downward, the three-phase slide block 320 is again simultaneously to the other end and second three-phase of the first three-phase shell fragment horizontal part The other end of shell fragment horizontal part applies downward pressure so that the first three-phase movable contact 3811 and the second three-phase movable contact 3812 move down, and final first three-phase movable contact 3811 and the second three-phase movable contact 3812 respectively with the first three-phase stationary contact The three-phase stationary contact 3822 of point 3821 and second is contacted.Now the height of the first three-phase intermediate plate 351 is equal to the second three-phase intermediate plate 352 and the 3rd three-phase intermediate plate 353 height.Because the first three-phase stationary contact installed part 393 and the second three-phase stationary contact are pacified Piece installing 394 is connected respectively with external power source, and the first three-phase movable contact 3811 and the second three-phase movable contact 3812 are respectively with One three-phase stationary contact 3821 and the second three-phase stationary contact 3822 are contacted.Therefore the second three-phase intermediate plate 352 and the 3rd 3 is folded Piece 353 completes to be connected respectively with external power source, and the first three-phase intermediate plate 351 is connected all the time by wire with conducting strip 392.Most Eventually when in the fully-inserted socket of 3-phase plug, circuit ON so that electric current Jing sockets and 3-phase plug are powered to electrical equipment. When 3-phase plug is extracted from the socket, the spring 391 of the other end of three-phase slide block 320 is fixed on, by the three-phase Slide block 320 is popped up, so cause the first three-phase movable contact 3811 and the second three-phase movable contact 3812 respectively with the first three-phase The three-phase stationary contact 3822 of stationary contact 3821 and second is separated, and disconnects circuit.Now, the first three-phase intermediate plate the 351, the 2nd 3 is contacted The three-phase intermediate plate 353 of phase intermediate plate 352 and the 3rd will not get an electric shock.
The overall waterproof electric-shock-resistant function of socket will be described in detail below,
If the water of outside enters the described first biphase receiving space 2111 and the second receiving space from the biphase jack 111 Inside 2112, because now biphase movable contact 281 and biphase stationary contact 282 are not in contact with therefore the He of the first biphase intermediate plate 251 Second biphase intermediate plate 252 not with power on, leaky will not occur.It is arranged at the upper of the biphase insulating body 210 The biphase water proof ring 230 on surface, is extruded jointly by the biphase insulating body 210 and upper casing 110, reaches sealing effectiveness so that Into the first biphase receiving space 2111 and the water of the second receiving space 2112, it is impossible to from the first biphase receiving space 2111 and At the opening of two receiving spaces 2112, permeated by between the upper surface of the biphase insulating body 210 and the inner surface of upper casing 110 Other positions to jack housing 100.The biphase installing hole 212 is sealed by biphase collision mat 240, can prevent into The water for entering the first biphase receiving space 2111 and the second receiving space 2112 infiltrates into jack housing 100 from biphase installing hole 212 Interior other positions.The biphase through hole 213 that the diapire 2103 of biphase insulating body 210 is provided with is by the biphase through hole 213 of screw-in Bolt sealed, can prevent the water into the first biphase receiving space 2111 and the second receiving space 2112 from communicating from two Hole 213 infiltrates into the other positions in jack housing 100.As can be seen here, receive into the first biphase receiving space 2111 and second Hold the other positions that the water in space 2112 cannot be infiltrated into further in jack housing 100, and then prevent the electricity of other positions Road and electronic component touch the water of outside.
If the water of outside enters the first three-phase receiving space 3111, the second three-phase and houses from the three-phase jack 112 The inside of the three-phase receiving space 3113 of space 3112 and the 3rd, because now three-phase movable contact 381 and three-phase stationary contact 382 do not connect Touch, thus the second three-phase intermediate plate 352 and the 3rd three-phase intermediate plate 353 not with power on, leaky will not occur.If The biphase water proof ring 330 of the upper surface of the three phase isolated body 310 is placed in, by the three phase isolated body 310 and upper casing 110 Common extruding, reaches sealing effectiveness so that into the first three-phase receiving space 3111, the second three-phase receiving space 3112 and the 3rd The water of three-phase receiving space 3113, it is impossible to from the first three-phase receiving space 3111, the second three-phase receiving space 3112 and the 3rd 3 At the opening of phase receiving space 3113, permeated by between the upper surface of the three phase isolated body 310 and the inner surface of upper casing 110 Other positions to jack housing 100.The first three-phase installing hole 3141 is sealed by three-phase collision mat 340, can be with Prevent other for infiltrating in jack housing 100 into the water of the first three-phase receiving space 3111 from the first three-phase installing hole 3141 Position.Second three-phase installing hole 3142 and the 3rd three-phase installing hole 3143 are sealed by bolt therein is screwed in, and can be prevented Water into the second three-phase receiving space 3112 and the 3rd three-phase receiving space 3113 is from the second three-phase installing hole 3142 and the 3rd Three-phase installing hole 3143 infiltrates into the other positions in jack housing 100.The wire connection hole 319 after wire is passed through, by Waterproof material is sealed, to prevent the water into the first three-phase receiving space 3111 from oozing from the wire connection hole 319 Thoroughly to the other positions in jack housing 100.As can be seen here, house empty into the first three-phase receiving space 3111, the second three-phase Between 3112 and the 3rd the water of three-phase receiving space 3113 cannot further infiltrate into other positions in jack housing 100, enter And prevent the circuit and electronic component of other positions from touching outside water.
