Embodiment
Be described in further detail below in conjunction with the utility model of embodiment, but execution mode of the present utility model is not limited thereto.
As Fig. 1～shown in Figure 12, a kind of secondary retaining mechanism comprises jack housing 1, slide block 2, plug body 3; Described jack housing 1 is provided with and once locks window 1-1, secondary locking slot 1-2, slide block location notch 1-3; Described slide block 2 is roughly " Z " font, and slide block 2 is provided with secondary unlocking device 2-1, slide block positioning table 2-2, anti-skid structure 2-3; Described plug body 3 is provided with a unlocking device 3-1, tight locking button 3-2, a secondary tight locking button 3-3; The described window 1-1 that once locks is rectangle, and a tight locking button 3-2 width dimensions of its width dimensions and plug body 3 is complementary, and its length is greater than the length of a tight locking button 3-2; Described secondary locking slot 1-2 is rectangle, and the secondary tight locking button 3-3 width of its width and plug body 3 is complementary, length greater than the distance of tight locking button 3-2, secondary lock tight locking button 3-3 and secondary tight locking button 3-3 length and; Described slide block location notch 1-3 is two, and once locks window 1-1 at grade, is respectively nearly ring flange end and ring flange end far away, and width and slide block positioning table 2-2 width are complementary, and length slightly is longer than the length of slide block positioning table 2-2; Described secondary unlocking device 2-1 is made up of two " 7 " word structures, two structure Cheng Jingxiang relations, and its front end has chamfering, and the spacing of two structures equals the profile of secondary tight locking button 3-3 on the plug body 3 apart from the twice that deducts secondary tight locking button 3-3 thickness; Described slide block positioning table 2-2 is a convex rectangular block of slide block inside top surface, its peripheral rounding; Described anti-skid structure 2-3 is trapezium structure, is big end near the plug body end; A described unlocking device 3-1 is " L " shape cantilever design, and its far-end is provided with press-button structure; A described tight locking button 3-2 is the convex rectangular block on the unlocking device 3-1 cantilever, and front end is the inclined-plane; Described secondary tight locking button 3-3 is buckled by two flag-shapeds and forms, and two buckle and are located at the unlocking device both sides one time, and the Cheng Jingxiang relation.
For realizing time-delay secondary locking function, need earlier slide block 2 to be contained on the jack housing 1, again plug body 3 is plugged together, to realize locking function one time; Then the shell that plugs together is carried out release, in releasing process, just can realize time-delay secondary locking function.
Specific implementation process is as follows:
The first step: hold plug body 3, a unlocking device 3-1 button of pressing on the plug body 3 does not unclamp, when a tight locking button 3-2 is in released state, pull back plug body 3, after drawing a segment distance, secondary tight locking button 3-3 can be in locking state automatically, and plug body 3 meeting stop motions stop drag action this moment.
Second step: pinch the anti-skid structure 2-3 of slide block 2 both sides, and pull back, slide block positioning table 2-2 is pulled to ring flange location notch 1-3 far away by the location notch 1-3 near ring flange, secondary tight locking button 3-3 will be in released state, stops drag action this moment.
The 3rd step: hold plug body 3, and pull back, can finish whole release actions.
The above-mentioned first step and between the 3rd step the action of untiing the secondary snap close is arranged, namely solution once lock and these two states of whole release between free that is to say delay effect at interval, this secondary retaining mechanism is the secondary retaining mechanism with delay function.
Improve for the optimization of secondary retaining mechanism and to be: adopt tight locking button 3-2 and secondary tight locking button 3-3 combined, realize the function of delaying time, can guarantee release for the first time and have delay effect in the releasing process fully, thereby guarantee can not cause because the connector separating rate is too fast connector can not satisfy the instructions for use of " back contact, elder generation disconnect ".
Adopt " L " shape cantilever design as a unlocking device, lock safe and reliablely, convenient for unlocking is quick.
Adopt two flag-shapeds to buckle as the secondary tight locking button, combine with secondary unlocking device on the slide block during release and just can finish the release action, lock safe and reliable, can anti-misoperation, thus the reliability of assurance connector.
Adopt Z-shaped slide block for making fool proof and secondary unlocking device, convenient for unlocking is quick, and the outward appearance simplicity generosity increases the attractive in appearance of connector.
Positioning table 2-2 on the slide block cooperates with the slide block location notch 1-3 of jack housing 1, the mechanism stable in the time of can keeping the normal use of connector and secondary release, thus the function that guarantees connector is normally implemented.
Each embodiment adopts the mode of going forward one by one to describe in this specification, and what each embodiment stressed is and the difference of other embodiment that identical similar part cross-references gets final product between each embodiment.
" embodiment " who speaks of in this manual, " another embodiment ", " embodiment ", etc., refer to concrete feature, structure or the characteristics described in conjunction with this embodiment and be included among at least one embodiment that the application's generality describes.A plurality of local appearance statement of the same race is not necessarily to refer to same embodiment in specification.Furthermore, when describing a concrete feature, structure or characteristics in conjunction with arbitrary embodiment, what advocate is to realize that in conjunction with other embodiment this feature, structure or characteristics also drop in the scope of the present utility model.
Although be described with reference to the utility model of a plurality of explanatory embodiment of the present utility model here, but, should be appreciated that, those skilled in the art can design a lot of other modification and execution modes, and these are revised and execution mode will drop within the disclosed principle scope and spirit of the application.More particularly, in the scope of, accompanying drawing open in the application and claim, can carry out multiple modification and improvement to building block and/or the layout of subject combination layout.Except modification that building block and/or layout are carried out with improving, to those skilled in the art, other purposes also will be tangible.
