The utility model provides a plug interface is convenient for joining in marriage of plug and becomes monitor terminal, its inserting groove 2 inside is equipped with elastic component, and at the extraction during operation of carrying out bayonet joint 4, elastic component can exert axial thrust to bayonet joint 4, and this thrust can reduce bayonet joint 4 and extract required dynamics, has reduced operating personnel's the operation degree of difficulty.
In the scheme, due to the existence of the elastic component, the connecting part between the plug connector 4 and the connecting sleeve 5 can bear larger stress, and the damage of threads is easily caused in the long-term use process, so that the service life of the plug component is influenced. Therefore, in the present embodiment, the sliding block 71 is provided with the notch 711, the stopper 53 that fits in the notch 711 is provided on the coupling sleeve 5, and the stopper 53 restricts the position of the sliding block 71, thereby reducing the stress applied to the coupling portion.
Specifically, the cutting groove 711 is disposed on one side wall of the sliding block 71, and the depth of the cutting groove 711 is greater than one half of the length of the sliding block 71, for example, if the sliding block 71 is a cube, the distance between the side wall where the cutting groove 711 is located and the parallel side wall is the length of the sliding block 71; if the sliding block 71 has an arc-shaped structure as shown in fig. 4, the length of the sliding block 71 can be understood as the arc length. The blocking piece 53 is arranged on the inner wall of the connecting sleeve 5, and the length of the blocking piece 53 is the same as the depth of the cutting groove 711 and is smaller than the distance between two adjacent sliding blocks 71.

At this time, the stopper piece 53 restricts the position of the slide block 71 to prevent the slide block 71 from rising upward, so that the axial stress applied to the lock housing 43 can be reduced. When the plug 4 needs to be pulled out, as shown in fig. 7, the connecting sleeve 5 is rotated to make the blocking piece 53 located between two adjacent sliding blocks 71, and at this time, the ascending motion of the sliding blocks 71 is no longer limited, so that the plug 4 can be pushed axially by the elastic component to push the plug 4 to exit the plug groove 2.
In addition, in order to avoid the abnormal rotation of the connection sleeve 5 caused by the misoperation of the operator or environmental vibration, the present embodiment further includes a locking device, and the structure of the locking device can be illustrated by fig. 8 and 9. As shown, the locking means includes a locking lever 62, a fitting groove 63, a receiving hole 61, and a locking hole 52. The receiving hole 61 is provided in the terminal body 1 on the circumferential side of the connecting sleeve 5, and a fitting groove 63 is provided at the top of the receiving hole 61. The locking lever 62 is disposed in the receiving hole 61, and a head 621 is disposed at a top end of the locking lever 62, and the head 621 is disposed in the insertion groove 63. The locking hole 52 is provided on the retainer ring 51, and the diameter of the locking hole 52 is the same as that of the receiving hole 61.
When the blocking pieces 53 are inserted into the slots 711, the locking holes 52 are aligned with the receiving holes 61, so that the lower ends of the locking rods 62 simultaneously pass through the locking holes 52 and the receiving holes 61, and the locking rods 62 limit the placement angle of the connecting sleeve 5, thereby preventing the connecting sleeve 5 from rotating abnormally. When the plug 4 needs to be pulled out, the locking rod 62 needs to be pulled out upwards first, so that the lower end of the locking rod 62 is disengaged from the locking hole 52. The connecting sleeve 5 will now be restored to its rotational capacity, and then the axial thrust of the resilient assembly will act on the plug 4 by rotating the connecting sleeve 5 so that the flaps 53 clear the slots 711.
Optionally, the locking device further includes a storage groove 64, the storage groove 64 is disposed at the top of the receiving hole 61 and is staggered from the insertion groove 63, and a depth of the storage groove 64 is smaller than a depth of the insertion groove 63. The storage groove 64 is used for accommodating the rod head 621 when the locking rod 62 is in the unlocked state, so that the locking rod 62 is prevented from being lost after being pulled out.
The working process of the above scheme is explained as follows:
the locking device is first checked to ensure that it is in the unlocked state and then the connecting sleeve 5 is rotated so that the stop piece 53 is located between two adjacent sliding blocks 71. The plug 4 is then inserted into the plug groove 2 and sufficient axial pressure is provided to the plug 4 so that the pin 41 is fully inserted into the receptacle 31. The connecting sleeve 5 is then rotated so that the flaps 53 engage into the slots 711, after which the plug connector 4 is fixed to the connecting sleeve 5 by means of the locking sleeve 43. Finally, the lock lever 62 is pressed down and the head 621 is placed inside the fitting groove 63, completing the locking of the coupling sleeve 5.
When the plug connector 4 is to be pulled out, the locking sleeve 43 is first separated from the connecting sleeve 5, after which the locking device is opened and the connecting sleeve 5 is rotated. At this time, the elastic component applies an axial thrust to the plug 4, so that the plug 4 leaves the plug groove 2, and the pulling-out action is completed.
The following explains the effects of the above scheme:
this embodiment provides a plug interface is convenient for joining in marriage of plug and is become monitor terminal, can provide axial thrust to the bayonet joint through elastic component, reduces the degree of difficulty of extracting of bayonet joint. Simultaneously, can carry on spacingly to elastic component through the separation blade on the connecting sleeve, avoid bayonet joint and connecting sleeve's the hookup location to bear too big axial stress. In addition, the device can also lock the placing angle of the connecting sleeve through the locking device, and the abnormal rotation of the connecting sleeve is avoided.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
