Specific implementation mode
The utility model provides a kind of secondary mousing device of connector.Below in conjunction with attached drawing to the utility model technical side
Case is described in detail, so that it is more readily understood and grasps.
A kind of secondary mousing device of connector is set to the split portion of plug 1 and socket 2 as shown in Figures 1 to 5,
Including the movable lockable mechanism being set on plug 1 and the lock mechanism being set on socket.Pass through movable lockable mechanism and lock
Mechanism for card realizes the secondary latch functions between plug 1 and socket 2.
Wherein, movable lockable mechanism includes the grab main body 3 that pivot is set on plug 1, grab main body 3 and plug 1 it
Between be equipped with elastic component for providing pivotable movement elasticity auxiliary force, which is preferably torsional spring.By torsional spring so that grab
The locking end of main body 3 is in pressed status, that is, keeps locking normality.
Grab main body 3 includes the locking grab 5 at driving end and T-shaped shape, drives and is provided on end for discharging or limiting
The slider mechanism 6 of 3 pivotable movement of grab main body, the slider mechanism 6 belong to the prior art, with the push button function one in referenced patents
It causes, i.e. CPA sliders, therefore repeats no more.
Lock mechanism is equipped with the locking trough 7 for carrying out locking limit to locking grab 5, and locking trough 7 is interior along plug 1
Plugging direction is equipped with level-one pintle hook lock position 8 and secondary latch screens 9.The T-type end of the both sides cell wall distance of locking trough 7 and locking grab 5
Head matches, i.e. the width of T-type end is slightly less than the distance between the 7 both sides cell wall of locking trough, on the one hand can reduce pintle hook lock machine
On the other hand the volume of structure can prevent grab main body 3 from generating shaking in locking trough 7.
When plug 1 is detached with socket 2, locking grab 5 is interferenceed with secondary latch screens 9, level-one pintle hook lock position 8 successively.
It further illustrates, as shown in figure 5, level-one pintle hook lock position 8 is two be set at the top of the both sides cell wall of locking trough 7
Protrusion, and two protrusions are oppositely arranged, be equipped between protrusion and the groove bottom of locking trough 7 for locking grab 5 by gap,
The gap does not mark.Secondary latch screens 9 is two limit protrusions being set in the groove bottom of locking trough 7.Limit protrusion direction
The side of plug 1 is mating inclined surface, which may make locking grab 5 to be directly coupled.The bottom surface of protrusion is less than limit
The top surface of position protrusion is higher than the top surface of the limit protrusion that is, when locking the disengaging limit protrusion of grab 5, during pulling away,
Ensure that protrusion can play secondary position-limiting action to locking grab 5.
In preferred embodiment, locking grab 5 is equipped with reinforcing rib 4, since the locking needs of grab 5 are locked for a long time
Card, and loosen hit it is more, in order to improve service life, locking grab 5 on be provided with reinforcing rib.
It specifically describes, when locking, it is only necessary to plug 1 is inserted into socket 2, locking grab 5 is directly from 8 bottom of level-one pintle hook lock position
The gap in portion passes through, and under the action of torsional spring, locking grab 5 is slipped over along the mating inclined surface of secondary latch screens 9, along with a sound
It is clamped the sound, locking grab 5 fastens locking with 9 phase of secondary latch screens.Locking state is as shown in Figure 3.
It when plug 1 is detached with socket 2, needs to slide and press slider mechanism 6, grab 5 is locked under pivotable movement and is tilted,
Lock grab 5 be higher than with secondary latch screens 9, pass through plug 1 and socket 2 at this time and be separated so that locking grab 5 and two level pintle hook lock
9 phase separation of position is realized to be detached from for the first time, and it is as shown in Figures 1 and 2 to loosen state for the first time.Due to the slider mechanism in separation process
6 still in inertia by pressure, and locking grab 5 is still in tilting state, locks grab 5 and 8 phase locking of level-one pintle hook lock position at this time,
Need the pressing unclamped to slider mechanism 6 that makes a short pause so that locking grab 5 is fallen after rise under the effect of torsion spring, then is detached, real
It is now detached from for second, the final separation for realizing plug 1 and socket 2 is illustrated in figure 4 discrete state.It is de- by locking twice
From, can prevent moment plug generate electric spark risk.
By above description it can be found that a kind of secondary mousing device of connector of the utility model, locking trough and T-type shape
The mating of locking grab stablize, can reduce the volume of connector while preventing locking grab from shaking.Have on locking grab and adds
Strengthening tendons improve structural strength, extend service life.Locking grab using T-type shape and level-one pintle hook lock position, secondary latch screens
It matches, realizes secondary latch functions.It is simple to lock grab, level-one pintle hook lock position and secondary latch retaining structure, is easy to die sinking molding,
And mating is reliable and stable, has stronger wear-resisting property and anti-deformation nature.It is simple for structure, it is ingenious in design, it is of low cost, it is easy to
It promotes.
The technical solution of the utility model is fully described above, it should be noted that the tool of the utility model
Body embodiment is simultaneously not limited by the description set out above, and those skilled in the art exist according to the Spirit Essence of the utility model
All technical solutions that structure, method or function etc. are formed using equivalents or equivalent transformation, all fall within this reality
Within novel protection domain.
