Embodiment
Below in conjunction with embodiment and accompanying drawing, to the detailed description further of the utility model do, but execution mode of the present utility model is not limited thereto.
Embodiment 1:
Of the present utility model be convenient to lock industrial electro connector plug and socket with the use of.In prior art, the general structure of socket is as shown in Figure 2:
Described socket comprises the Socket casing 21 that front end is hollow cylindrical, the columned socket insulator 23 be arranged in Socket casing 21, and this socket insulator 23 is provided with jack 22.
The industrial electro connector plug structure being convenient to lock of the present utility model as shown in Figure 1, comprises the plug casing 11 that front end is hollow cylindrical, the contact pin 13 being arranged on the columned pin insulator 12 in plug casing 11 and being plugged on pin insulator 12.
The internal diameter of described plug casing 11, slightly larger than the external diameter of Socket casing 21, enable Socket casing 21 front end snap in plug casing 11 front end, and Socket casing 21 is close to plug casing 11 inwall after snapping in plug casing 11.
Described plug casing 11 is outer is also arranged with back-up ring 14, back-up ring 14 is made up of with the mode split that recess is relative the baffle plate that two cross sections are curved, as shown in Figure 1, the center of circle of two baffle plates, central axis all overlap and have between two baffle plates between the relative side of gap and baffle plate two and have gap structure after split.
Described back-up ring 14 is outer is also arranged with binding ring 15, and the length of described binding ring 15 is less than the length of back-up ring 14 and binding ring 15 can rotate and moving axially along back-up ring 14 on back-up ring 14.
In the present embodiment, the outer sheathed back-up ring 14 of plug casing 11, the outer sheathed binding ring 15 of back-up ring 14, the effect of back-up ring 14 and binding ring 15 is all for locking plug casing 11.When socket is not connected with plug, binding ring 15 is stuck in back-up ring 14 rear end, is tightly pressed in by back-up ring 14 on plug casing 11; When plug is connected with socket, only needs Socket casing 21 to snap in plug casing 11, then push binding ring 15 to plug casing 11 front end, plug casing 11 preferably adopts soft housing, such as plastics or rubber shell.Because back-up ring 14 is spliced by two baffle plates, therefore not have under External Force Acting plug casing 11 without extruding, when binding ring 15 pushes plug casing 11 front end to, back-up ring 14 compresses by binding ring 15, thus plug casing 11 is pressed on Socket casing 21 by back-up ring 14, thus realize the locking of plug and socket, its installation is fast very convenient, because binding ring 15 is by swelling, between itself and back-up ring 14, there is larger extruding force, thus can not move on back-up ring 14, plug and socket stable connection can be ensured.
Embodiment 2:
On the basis of embodiment 1, in the present embodiment, plug is improved as follows:
The described back-up ring 14 outer wall front end outer wall of the close front end of back-up ring 14 (i.e. on) is provided with snap ring 141, and snap ring 141 and back-up ring 14, plug casing 11 front end hollow cylindrical portion are all coaxial, and snap ring 141 is close to back-up ring 14 outer wall and is arranged.The front end face of described binding ring 15 is provided with the annular groove 16 coordinated with snap ring 141.
In the present embodiment, back-up ring 14 front end arranges a snap ring 141, can carry out spacing to binding ring 15, binding ring 15 is front pushing through in journey until push away before stopping when snap ring 141 snaps in annular groove 16, can prevent binding ring 15 from releasing outside back-up ring 14 on the one hand, another is convenient is also convenient to user and grasps stopping opportunity, is convenient to install.
Embodiment 3:
On the basis of embodiment 1 or embodiment 2, also plug is improved as follows in the present embodiment:
Because general Socket casing 21 outer wall front end is provided with external screw thread, in the present embodiment, the described plug casing 11 inwall front end inwall of the close front end of plug casing 11 (i.e. on) is provided with the internal thread matched with the external screw thread of Socket casing 21 outer wall.Described back-up ring 14 outer wall is provided with external screw thread, and described binding ring 15 inwall is provided with the internal thread matched with the external screw thread of back-up ring 14 outer wall.
Socket casing 21 outer wall and plug casing 11 inwall arrange the screw thread matched, the stability that plug and socket connects can be strengthened further, but need to sacrifice certain set-up time, when therefore taking into account the convenience of stability and installation, the pitch suitably increasing screw thread can be considered simultaneously.In the present embodiment, the pitch of the external screw thread of Socket casing 21 outer wall and the internal thread of plug casing 11 inwall is all not less than 1.75.
Described back-up ring 14 outer wall and binding ring 15 inwall arrange the screw thread matched, mainly increase the frictional force between back-up ring 14 and binding ring 15, binding ring 15 is convenient to be locked on back-up ring 14, further increase stability, the set-up time that same needs sacrifice is certain, when therefore taking into account the convenience of stability and installation, the pitch of the external screw thread of back-up ring 14 outer wall and the internal thread of binding ring 15 inwall is all not less than 1.75 simultaneously.
In order to increase the frictional force of binding ring 15 outer wall, described binding ring 15 outer wall is provided with latch 151.
Below be only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, not departing from the some improvements and modifications under the utility model principle prerequisite, protection range of the present utility model should be considered as.
