Fig. 1 is a kind of structural schematic diagram of the secondary locking system of connector of the utility model.
Fig. 2 is a kind of configuration schematic diagram of the secondary locking system of connector of the utility model.
Fig. 3 be a kind of connector of the utility model secondary locking system in grab main body structural schematic diagram.
Specific implementation mode
The utility model provides a kind of secondary locking system 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 locking system of connector is set to the split portion of plug 1 and socket 2 as shown in Figure 1 to Figure 3,
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 4 for providing pivotable movement elasticity auxiliary force, which is preferably torsional spring.By torsional spring so that card
The locking end of hook 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.
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, level-one pintle hook lock position 8 is the protrusion being set at the top of the side channel wall of locking trough 7, protrusion and pintle hook lock
Between the groove bottom of slot 7 be equipped with for locking grab 5 by gap, which does not mark.Secondary latch screens 9 is to be set to pintle hook lock
Limit protrusion in the groove bottom of slot 7.Limit protrusion is mating inclined surface towards the side of plug 1, which can make
Grab 5 must be locked directly to be coupled.The bottom surface of protrusion is less than the top surface of limit protrusion, i.e., when locking the disengaging limit protrusion of grab 5,
It is higher than the top surface of the limit protrusion, during pulling away, it is ensured that protrusion can play secondary position-limiting action to locking grab 5.
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.
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
Position 9 phase separation realize for the first time be detached from, due to the slider mechanism 6 in separation process still inertia by pressure, locking grab 5 according to
It is so in tilting state, locks grab 5 and 8 phase locking of level-one pintle hook lock position at this time, the release that needs to make a short pause is to slider mechanism 6
Pressing so that locking grab 5 is fallen after rise under the effect of torsion spring, then is detached, and is realized second and is detached from, it is final realize plug 1 with
The separation of socket 2.It is detached from by locking twice, can prevent moment plug from generating the risk of electric spark.
By above description it can be found that a kind of secondary locking system of connector of the utility model, using the lock of T-type shape
Tight grab is matched with level-one pintle hook lock position, secondary latch screens, realizes secondary latch functions.Lock grab, level-one pintle hook lock position and two
Grade pintle hook lock bit architecture is simple, is easy to die sinking molding, and mating is reliable and stable, has stronger wear-resisting property and anti-deformation nature.
Slider mechanism can limit grab main body, effectively prevent maloperation.It is simple for structure, it is ingenious in design, it is of low cost, it is easy to push away
Extensively.
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.
