Including gasoline, diesel oil, urea, methanol, gas and water etc..
Can whether male contact 1 be fully inserted into famale connector 2, be bounced according to press-button structure 3 to determine；Famale connector 2
Front end portion is designed with dustproof construction 4, and the existing dust-proof function of dustproof construction 4 ensures that press-button structure 3 can be carried out rationally simultaneously
Assembling, and can guarantee that press-button structure 3 is only placed in the rectangular channel 22 of famale connector；The only installation of male contact 1 is clamped in place, and is pressed
Rectangle neck 33 on button structure 3 can block the clamping between the second annular boss 14 of male contact and first annular boss 13
Portion 11, male contact 1 is set firmly to be locked into famale connector 2；Inside the fully-inserted famale connector 2 of male contact 1, the reset of press-button structure 3
Spring 34 can recover promoting button structure 3 and move upwards, until the upper surface 311 of the buckle structure of press-button structure touches square
211 can not move out at the top of the inwall of shape groove, and now rectangle neck 33 also tightly encloses the Access Division 11 of male contact, ensure
The reliability of locking.
As shown in Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Figure 11, famale connector 2 is using the structure of push button, and press-button structure is including pressing
Button 31, circular channel 32, rectangle neck 33 and lower convexity 35, the button 31 at finger pressing use arc, rectangular channel
Upper surface 21, contacted when button 31 is pressed, when male contact 1 and 2 locking state of famale connector, the inwall of rectangle neck
Bottom surface 331 is bonded with the Access Division 11 of male contact, the width of rectangle neck 33 and the first annular annular boss of boss 13 and second
The external diameter of Access Division 11 between 14 is equal, plays a part of tightly blocking male contact, and the bottom design of press-button structure 3 is convex under having
35 being played, its external diameter is less than the internal orifice dimension of back-moving spring 35 so that back-moving spring 34 entangles lower convexity 35, plays a part of positioning,
Prevent back-moving spring 34 along surrounding slip, come off generation so that back-moving spring 34 is stable to be contacted with press-button structure, finger
The button 31 at place is connected with the lower convexity 35 of circular channel 32, rectangle shelves ring 33 and bottom for integral type structure installed in famale connector
In the rectangular channel 22 in portion, the vertical inwall bottom for being placed on rectangular channel 22 is fixed in the lower end 341 of back-moving spring 34, in rectangular channel 22
Inwall bottom design have a spring boss 36, the surrounding of spring boss 36 be provided with different height three horizontal projections 361,
362nd, 363, play a part of strengthening the lower end of fixed reset spring 34, the upper end 342 of back-moving spring 34 is free vertical state.
As shown in Fig. 6, Fig. 7 and Fig. 8, the left and right end portions of famale connector are respectively designed with left buckle 46, right jamming button 47 and a left side and determined
Position block 44, right locating piece 45, buckle are arranged to wrench shape, and the lower end of dust cap 41, which is provided with, to be used to be arranged on to rotary shaft 37
Rotating hole 412, be equipped with positioning hole 432, the transition circle cambered surface of left buckle on left dust-proof snap-fastener 42 and right dust-proof snap-fastener 43
461st, the transition circle cambered surface 471 of right jamming button uses arc-shaped, and the clamping that 462, right jamming button is faced in the clamping of left buckle directly faces 472 directly
Planar structure is designed as, left locating piece 44, right locating piece 45 are provided with the certain distance of buckle, the one side of locating piece can
To verify whether dust cap 41 reasonably closes, if dust cap 41 is tight without closing, dust-proof snap-fastener can not by locating piece and
It can not be docked with buckle, another aspect locating piece can ensure dual clamping buckle so that dust-proof snap-fastener is firmly clamped on pintle hook lock
On so that the phenomenon generation that joint will not fall off in the case where being given a shock, shift.
As shown in Fig. 4, Fig. 5 and Fig. 8, the dust cap 41 of the leading section of famale connector 2 design, it can be revolved around rotary shaft 37
Turn, rotary shaft 37 is designed in the front end of famale connector end, and dust cap 41 can be that certain rotation is carried out around famale connector, dust-proof
The left and right ends of lid 41 are respectively designed with left dust-proof snap-fastener 42 and right dust-proof snap-fastener 43, and the first elastic elasticity of cam 421, second is convex
Button 431 uses inverted triangular shape so that has certain inclined-plane, so left dust-proof snap-fastener 42 and right dust-proof snap-fastener 43 can be square
Being locked by left buckle 46 and right jamming button 47 just, dust cap 41 is covered on male contact 1, plays a part of dust-proof anti-gray.
The present invention application method be：When male contact 1 needs inserting, user is first the dustproof construction 4 of famale connector 2
In open mode, the spring boss 36 lower end 341 of the back-moving spring 34 of press-button structure 3 being fixedly mounted in rectangular channel 22
On, three horizontal projections 361,362,363 of the surrounding different height of spring boss 36, back-moving spring 34 can be securely fixed
In rectangular channel 22, then press-button structure 3 is put into the rectangular channel 22 of famale connector end, the lower convexity 35 on press-button structure is just
Put into back-moving spring 34 well, after press-button structure 3 places, rotate dust cap 41 around rotary shaft 37 and close dust cap 41
On, press-button structure 3 or so is fixed in rectangular channel 22, does not allow to move left and right, then by left dust-proof snap-fastener 42, right dust-proof press
The rotation of button 43 snaps onto the left buckle 46 for being arranged on famale connector both ends, on right jamming button 47, left dust-proof snap-fastener 42, right dust-proof snap-fastener 43
The elastic cam 421 of upper first, the second elastic cam 431 use inverted triangular structure, guarantee has certain inclined-plane, and the moon connects
Transition circle cambered surface 461, the transition circle cambered surface 471 of right jamming button 47 of the left buckle 46 of head use special arc-shaped, ensure dust-proof
Snap-fastener easily can enter in buckle, the design of the left locating piece 44, right locating piece 45 at famale connector both ends ensure that it is dust-proof by
The positioning of button, while strengthen locking effect.User press press-button structure 3 button 31 so that the stress of back-moving spring 34 by
To compression, press-button structure 3 is overall to be moved downward, at the circular channel 32 of press-button structure 3 and the center of famale connector connecting portion
In concentric position, male contact 1 is by dust cap 41, press-button structure 3, into famale connector 2, until male contact 1 inserts in place,
At this moment user can be checked that press-button structure 3 smoothly can bounce with press-button structure 3, then the inserting of male contact 1 is arrived
Position, if press-button structure 3 does not bounce, position does not change, then male contact 1 is no inserts in place；When inserting in place, button knot
Structure 3 can smoothly be upspring in the presence of back-moving spring 34, lower surface 331 and sun until the rectangle neck 33 of press-button structure 3
The Access Division 11 of joint 1 is touched, and at this moment the upper surface 311 of press-button structure 3 also stops because hindering the inside top 211 of rectangular channel
Motion, so as to which male contact 1 is locked in famale connector 2.
When male contact 1 needs to be pulled outwardly out, for user firstly the need of that will press button 31, the compressing of press-button structure 3 is multiple
Position spring 34 so that back-moving spring 34 is by compression, and press-button structure 3 is constantly toward moving downward, until the circle of press-button structure 3
