Embodiment
The embodiment one of connector assembly of the present invention: as shown in Figure 1, comprise and connect dust cap 1 and connect device housing 2, dust cap 1 comprises by the lid in the spliced eye of spiral-lock after forward direction on connector shell 1, connector shell 2 is provided with the bulge loop 20 extended forward on the apertura lateralis edge of its spliced eye, lid be provided with extend before and after axis, opening annular groove 10 backwards, when lid spiral-lock is on connector shell 2, bulge loop 20 is positioned at annular groove 10.
Bulge loop 20 is provided with opening lock groove 21 radially.The axis that lid is extended along front and back by fixed mount 100 is rotatably equipped with rotating shaft 11, and rotating shaft 11 fore-and-aft direction extends and its rear end is provided with lock dog 110.When lid spiral-lock is on connector shell 2, lock dog 110 corresponds to the notch position of lock groove 21 in radial directions.Lock dog 110 have in the rotational travel around its rotating shaft turn in lock groove 21 and with the front side cell wall of the lock groove 21 locking position that coordinates of block and produce from lock groove 21 and dust cap 1 can be made relative to the solution lock-bit of connector shell 2 movement from back to front in a forward direction.
Lid is also provided with the retaining mechanism be in transmission connection with lock dog 110, retaining mechanism comprises makes lock dog remain on the elastic component of locking position and when stressed, make lock dog overcome the elastic force of elastic component and be turned to the load portion separating lock-bit by locking position.
In the present embodiment, load portion rotates the button 12 be assemblied on lid, downward-extension on button 12 and its pivot center extend at fore-and-aft direction, transmission mechanism comprises the button gear 121 be located on button 12, the axis of button gear 121 overlaps with the pivot center of button 12, rotating shaft 11 is provided with lock dog gear 111, and lock dog gear 111 and button gear 121 are in transmission connection thus realize being in transmission connection between retaining mechanism and lock dog.Button press 12 rotation can be realized lock dog 110 and rotate with rotating shaft 11 by the engaged transmission between gear.When reality uses, consider space factor, button gear and lock dog gear can be at circumferencial direction and incomplete gear, and the angle of circumference only needing gear mesh to answer is greater than the angle of circumference between the locking position reconciliation lock-bit of lock dog.
Elastic component is connected with button and applies active force by button to lock dog and keep lock dog to be positioned at locking position.In the present embodiment, the lower end of button is located in the rotating shaft of button 12, button gear 121 is provided with the upper end of button 12, and elastic component is the stage clip 13 be located between lid and button, the rotation trend that stage clip 13 makes it have counterclockwise by applying outside elastic force to button 12.On button 12, also before and after it, both sides are provided with buckle 122, correspondingly, lid is provided with the draw-in groove with buckle 122 clamping, stage clip 13 pairs of buttons 12 exert a force and are pressed in the draw-in groove on lid by the buckle 122 on button 12, draw-in groove is spacing and it can not be made to be rotated further to button, now, button 12 just makes lock dog 110 be arranged in lock groove 21 by the engaged transmission of button gear 121 pairs of lock dog gears 111, namely be in locking position, such dust cap 1 can be locked reliably to be connected on connector shell 2 and be realized dust seal.
During unblock, press the upper end of button 12 and its elastic force overcoming stage clip 13 is inwardly rotated, button 12 is rotated by button gear 121 drive shaft 11 and lock dog 110 is produced from lock groove 21, and now take off dust cap forward, releasing process is very convenient.
Connector assembly of the present invention can make dust cap connect reliably on the connectors by locking mechanism, avoids dust cap and connector in vibrations process to depart from, causes dust-proof inefficacy; In use, pressing button just can by smooth for dust cap spiral-lock on connector shell, and release button just realizes dust cap and is connected with the locking of connector shell, and when needing to pull down, dust cap is also extracted by button press, very convenient to use.
The embodiment two of connector assembly of the present invention: be with the difference of embodiment one, load portion is the driving lever be wholely set with lock dog rotating shaft, driving lever is radial in lock dog rotating shaft to be extended, elastic component is the extension spring be connected on driving lever, extension spring is supplied to driving lever elastic force and is supplied to by driving lever the active force that lock dog rotates to locking position, lid is also provided with the position limiting structure when lock dog turns to locking position place with driving lever, driving lever being carried out to circumferential block, lock dog can be made to turn to solution lock-bit by locking position by rotating lever.
The embodiment three of connector assembly of the present invention: be with the difference of embodiment one, lock dog rotating shaft and button do not arrange gear, and realize being in transmission connection of lock dog rotating shaft and button by driving-belt.
The embodiment four of connector assembly of the present invention: be with the difference of embodiment one, elastic component is be set in the torsion spring in button rotating shaft.
The embodiment five of connector assembly of the present invention: be with the difference of embodiment one, elastic component is the extension spring be connected between lid and lock dog, and its elastic force directly acts on lock dog not by the indirect test specimen of button.
The embodiment of dust cap of the present invention: as Figure 2-3, its concrete structure is identical with the structure of the dust cap in the embodiment of above-mentioned connector assembly, repeats no more herein.
