Abstract
A bayonet type quick-connection locking mechanism mainly comprises a connector plug shell, an insulator, a connecting ring, a limit ring, a movable pressing ring, springs, a spring mounting groove and a connector socket shell. When in locking, the connecting ring is pushed to move forwards, and changes to rotate from the straight motion after being obstructed by a limit groove, a clamping pin is fixed in a limit hole for locking a connecting mechanism after the connecting ring rotates 30 degrees to the right. The bayonet type quick-connection locking mechanism has the advantages that the locking can be realized by rotating the connecting ring 30 degrees to the right after being pushed forwards to the position, five limiting mechanism in two categories are further provided except for the locking force provided by the springs which are evenly distributed in the aspect of design of locking reliability, and compared with other quick locking mechanisms, the bayonet type quick-connection locking mechanism is more compact, and is beneficial for realizing the small-size of connectors.
Description
Affiliated technical field
The utility model relates to a kind of bayonet coupling mechanism that can lock fast, is mainly used in the quick connection of electric connector.
Background technology
Along with the development of electronic design technology, the connector microminaturization development trend that is inevitable, and the design size of retaining mechanism directly has influence on the size of whole connector.Simultaneously, connector is subjected to the restriction of usage space, requires connected mode simple and quick, and loaded down with trivial details connected mode obviously is not meet the connector development trend.Present retaining mechanism mainly comprises screw-type, bayonet type, plug-type and three-start screw formula etc.Though screw-type locking mechanism size is less, need the rotation multi-turn could realize the locking of mechanism afterwards.Plug-type and three-start screw formula retaining mechanism be connected locking fast, but the size of retaining mechanism is relatively large.What the utility model adopted is the bayonet type retaining mechanism, this connection retaining mechanism, and compact conformation, operation is rapid, and design has multiple anti-loose structure, the reliability of assurance mechanism locking.
Summary of the invention
The purpose of this utility model provides a kind of quick retaining mechanism of bayonet type that can realize the connector miniaturization, its compact conformation, and operation only needs dextrorotation just can realize reliable connection for 30 ° rapidly.
The utility model is taked following design:
This bindiny mechanism mainly comprises connector plug housing, insulator, connecting ring, spacing ring, movable pressure ring, spring, spring mounting groove and connector body housing.Connecting ring is provided with three bails, and the connector body housing is provided with gathering sill, stopper slot and spacing hole.During locking, promote connecting ring, bail on the connector ring travels forward along the gathering sill on the housing, after being subjected to the stopping of stopper slot, become rectilinear motion into rotatablely moving, the angle between spacing hole and the gathering sill is 30 °, after 30 ° of connecting ring rotations, bail just can be fixed among the spacing hole, and bindiny mechanism's locking is finished.For guaranteeing the reliability of locking, 8 uniform springs are set, act on the movable pressure ring.Movable pressure ring links to each other with connecting ring, so just power can be delivered on the connecting ring, and uniform spring can guarantee the evenly reliable of coupling mechanism force, can reduce the size of single spring simultaneously, thereby be convenient to reduce the design size of whole retaining mechanism.For the reliability of further guaranteeing to lock, increased spacing ring in the retaining mechanism, be provided with two groups of uniform flutings that are spaced apart 30 ° in the above, match with two corresponding catchings on the connecting ring, behind connector locking, catching on the connecting ring is just sunk in the fluting of spacing ring, so just can further increase the reliability of retaining mechanism.This locking mechanism structure compactness is 3mm at the shared in the radial direction thickness of connector, increases on the diametric(al) to be of a size of 6mm, helps the miniaturization Design of connector.
The utility model has the advantages that: this bindiny mechanism adopts the bayonet type locking mode, after before connecting ring, shifting the position onto, as long as dextrorotation just can realize locking for 30 °, at the reliable lock design aspect, provide the coupling mechanism force except using uniform spring, also design has two kinds of five position-limit mechanisms, guarantee the reliability of locking, with respect to other quick retaining mechanism, the mechanism of this connector is more compact, helps realizing the miniaturization Design of connector.

Embodiment
In Fig. 1, adopt the fixed form that closes up between plug casing of connector (1) and the insulator (2), utilize the crushed element that is absorbed in insulator of housing wall to realize fixing between the two.Have 8 uniform spring mounting grooves on the insulator (2), 8 cylindrically coiled springs (3) are positioned over respectively in the spring groove, are used to provide syndeton required coupling mechanism force.Movable pressure ring (4) acts on the spring, its effect is that the actuating force on the connecting ring (5) is delivered on the spring, design has 8 spacer pins to match with spring mounting groove on the insulator on the movable pressure ring, connecting ring can only slide front and back on the direction of spring groove like this, can avoid producing relative rotation between movable pressure ring and the spring.Connecting ring (5) is installed in after the movable pressure ring, and it mainly acts on is to match with socket part to realize the locking of entire mechanism.Its external Design has 3 bails (6) (not uniform, as to be used to prevent that the mistake of connector from connecting), when connecting ring has external force to drive, the gathering sill (8) of bail on the Socket casing (7) is to front slide, when bail arrives the gathering sill bottom, be subjected to the constraint of stopper slot (9), stop to slide.At this moment, apply clockwise torsional moment to connecting ring, bail will rotate along stopper slot, and after rotating 30 °, bail drops in 3 location holes (seeing that Fig. 4 marks) that are mated, and the retaining mechanism connection puts in place.The back of connecting ring is provided with spacing ring (10), being provided with spacing draw-in groove (seeing that Fig. 3 marks) above it matches with catching (seeing that Fig. 3 marks) on the connecting ring, after syndeton realized locking, catching was absorbed among the spacing draw-in groove, thereby further increases the reliable lock of bindiny mechanism.The connected mode of catching and insulator is identical with the connected mode of movable pressure ring and insulator, in the catching also design have 8 spacer pins to match with spring mounting groove on the insulator, thereby play the effect of anti-rotation.Be provided with jump ring (11) behind the spacing ring, be used for the displacement of limit slippage part.
