461, the transition circle cambered surface 471 of right jamming button all uses arc-shaped, the clamping of left buckle to face 462 directly, the clamping of right jamming button faces 472 directly
Being designed as planar structure, be provided with left locating piece 44, right locating piece 45 in the certain distance of buckle, the one side of locating piece can
The most reasonably closing with checking dust cap 41, if dust cap 41 does not close tight, the most dust-proof snap-fastener can not be by locating piece
Cannot dock with buckle, on the other hand locating piece ensure that 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 of being given a shock, shift.
As shown in Fig. 4, Fig. 5 and Fig. 8, the dust cap 41 of famale connector 2 leading section design, it is possible to revolve around rotary shaft 37
Turning, rotary shaft 37 designs in famale connector end foremost, and dust cap 41 can be dust-proof for carry out certain rotation around famale connector
The left and right of lid 41 is respectively designed at two ends with the dust-proof snap-fastener of left dust-proof snap-fastener 42 and the right side 43, and the first elastic cam 421, second is elastic convex
Button 431 employing inverted triangular shape so that having certain inclined-plane, so left dust-proof snap-fastener 42 and the dust-proof snap-fastener in the right side 43 can be square
Being locked by left buckle 46 and right jamming button 47 just, dust cap 41 covers on male contact 1, plays the effect of dust-proof anti-gray.
The using method of the present invention is: when male contact 1 needs plug-in mounting, and user is first the dustproof construction 4 of famale connector 2
It is in open mode, the spring boss 36 being fixedly mounted in rectangular channel 22 lower end 341 of the back-moving spring 34 of press-button structure 3
On, three of described spring boss 36 surrounding differing heights horizontal protruding 361,362,363, it is possible to securely fixed by back-moving spring 34
In rectangular channel 22, press-button structure 3 being put into the rectangular channel 22 of famale connector end subsequently, the lower convexity 35 on press-button structure is just
Put in back-moving spring 34 well, after press-button structure 3 places, rotate dust cap 41 around rotary shaft 37 and dust cap 41 is closed
On, press-button structure about 3 is fixed in rectangular channel 22, does not allows to move left and right, then by left dust-proof snap-fastener 42, right dust-proof press
Detain 43 turn buckles to be connected on and be arranged on the left buckle 46 at famale connector two ends, right jamming button 47, left dust-proof snap-fastener 42, right dust-proof snap-fastener 43
The upper first elastic elastic cam 431 of cam 421, second use del structure, it is ensured that having certain inclined-plane, the moon connects
The transition circle cambered surface 461 of left buckle 46 of head, the transition circle cambered surface 471 of right jamming button 47 use special arc-shaped, it is ensured that dust-proof
Snap-fastener can enter card easily and smash, the left locating piece 44 at famale connector two ends, the design of right locating piece 45 ensure that dust-proof by
The location of button, strengthens locking effect simultaneously.The button 31 of user pressing press-button structure 3 so that back-moving spring 34 stress is subject to
To compression, press-button structure 3 entirety moves downward, until the circular channel 32 of press-button structure 3 and the center of famale connector connecting portion
In the position of concentric, male contact 1, by dust cap 41, press-button structure 3, enters famale connector 2, until male contact 1 plug-in mounting puts in place,
At this moment user can check with press-button structure 3, and press-button structure 3 can bounce smoothly, then male contact 1 is inserted to
Position, if press-button structure 3 does not bounces, position does not changes, then male contact 1 does not has plug-in mounting to put in place；When plug-in mounting puts in place, button is tied
Structure 3 can be upspring under the effect of back-moving spring 34 smoothly, until the lower surface 331 of the rectangle draw-in groove 33 of press-button structure 3 and sun
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 the inside top 211 of rectangular channel hinders
Motion, thus male contact 1 is locked in famale connector 2.
When male contact 1 needs to be pulled outwardly out, user will be firstly the need of pressing button 31, and press-button structure 3 compressing 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
Shape passage 32 and male contact 1 are in same shaft core position, and male contact 1 just can pull out in famale connector 2, discharge button 31,
Press-button structure 3 in a state of nature, when press-button structure 3 needs to take out, it is only necessary to pull the left card of famale connector end respectively
Button 46, right jamming button 47, take out left dust-proof snap-fastener 42 and the dust-proof snap-fastener in the right side 43, dust cap from left buckle 46, right jamming button 47
41 just can take out to external rotation, press-button structure 3 around rotary shaft 37 in rectangular channel 22, it can be seen that male contact 1
Take out very convenient, and the taking-up of press-button structure 3 is the most simple and convenient with installation.
The present invention loads and unloads reasonable and convenient and has dustproof construction 4, and the design of dustproof construction 4 ensure that press-button structure 3
Can be fixed in the rectangular channel 22 of famale connector 2 left and right completely, will not change along with vibration, and the setting of dust cap 41
Meter has the effect of dust-proof anti-gray, and reliable lock is greatly improved simultaneously, and male contact 1 and famale connector 2 are easy to loading and unloading, and sealing can
Lean on, it is possible to play the features such as the effect of dust-proof anti-gray, and with low cost, simple and ingenious structure.
