Embodiment
The present invention will now be described in further detail with reference to the accompanying drawings and the accompanying drawings, but embodiments of the present invention
Not limited to this.
Embodiment 1：
As shown in figure 1, the splicing type attachment means for electrical connection, including plug and socket.
The socket include front end in hollow cylindrical Socket casing 21, be arranged on it is columned in Socket casing 21
Jack 22 is provided with socket insulator 23, the socket insulator 23.
The plug include front end in hollow cylindrical plug casing 11, be arranged on it is columned in plug casing 11
Plug insulator 12 and the contact pin 13 being plugged on plug insulator 12.
The internal diameter of the plug casing 11 is slightly larger than the external diameter of Socket casing 21, the front end of Socket casing 21 is caught in slotting
The front end of casing 11, and Socket casing 21 is caught in after plug casing 11 and is close to the inwall of plug casing 11.
The plug casing 11 is outer to be also arranged with back-up ring 14, and back-up ring 14 is by the curved baffle plate in two cross sections with recess phase
To mode split constitute, structure after split is as shown in figure 1, the centers of circle of two baffle plates, central axis are overlapped and two gears
Between plate have gap be baffle plate two relative sides between have gap.
The back-up ring 14 is outer to be also arranged with retaining ring 15, and the length of the retaining ring 15 is less than length and the locking of back-up ring 14
Ring 15 can be rotated on back-up ring 14 and along the axial movement of back-up ring 14.
In the present embodiment, it is arranged outside plug casing 11 outside back-up ring 14, back-up ring 14 and is arranged retaining ring 15, back-up ring 14 and retaining ring
15 effect is to be used for locking plug housing 11.When socket and not connected plug, retaining ring 15 is stuck in the rear end of back-up ring 14, will keep off
Circle 14 is tightly pressed against on plug casing 11；When plug is connected with socket, it is only necessary to which Socket casing 21 is caught in plug casing 11,
Then retaining ring 15 is pushed to plug casing 11 front end, plug casing 11 is preferred to use soft housing, such as plastics or rubber
Housing.Because back-up ring 14 is spliced by two baffle plates, thus no external force effect under to plug casing 11 without extruding, work as lock
When tight ring 15 pushes 11 front end of plug casing to, retaining ring 15 compresses back-up ring 14, so that plug casing 11 is pressed on by back-up ring 14
On Socket casing 21, so as to realize the locking of plug and socket, it installs very convenient quick, because retaining ring 15 is by swelling,
It has larger extruding force between back-up ring 14, so as to will not be moved on back-up ring 14, can guarantee that plug and socket connection is steady
It is fixed.
Embodiment 2：
On the basis of embodiment 1, in the present embodiment, plug is improved as follows：
The outer wall front end of back-up ring 14（I.e. on the outer wall of the close front end of back-up ring 14）Be provided with snap ring 141, snap ring 141 with
Back-up ring 14, the front end hollow cylindrical portion of plug casing 11 are coaxial, and snap ring 141 is close to the setting of the outer wall of back-up ring 14.The retaining ring
15 front end face is provided with the annular groove 16 coordinated with snap ring 141.
In the present embodiment, the front end of back-up ring 14 sets a snap ring 141, and spacing, retaining ring 15 can be carried out to retaining ring 15
Pushed away before stopping when being caught in annular groove 16 up to snap ring 141 during preceding pushing away, on the one hand can prevent retaining ring 15 from releasing back-up ring
It is another conveniently to also allow for user's grasp stopping opportunity outside 14, it is easily installed.
Embodiment 3：
On the basis of embodiment 1 or embodiment 2, also plug and socket is improved as follows in the present embodiment：
The outer wall front end of Socket casing 21 is provided with external screw thread, the inwall front end of plug casing 11（That is plug casing
On the inwall of 11 close front end）It is provided with the internal thread being engaged with the external screw thread of the outer wall of Socket casing 21.The back-up ring 14
Outer wall is provided with external screw thread, and the inwall of retaining ring 15 is provided with the internal thread being engaged with the external screw thread of the outer wall of back-up ring 14.
The outer wall of Socket casing 21 and the inwall of plug casing 11 set the screw thread being engaged, and can further enhance plug and insert
The stability of seat connection, but need to sacrifice certain set-up time, therefore when taking into account stability and the convenience installed simultaneously,
It is contemplated that suitably increasing the pitch of screw thread.The external screw thread of the outer wall of Socket casing 21 and the inwall of plug casing 11 in the present embodiment
The pitch of internal thread is not less than 1.75.
The outer wall of back-up ring 14 and the inwall of retaining ring 15 set the screw thread being engaged, and mainly increase back-up ring 14 and retaining ring
Frictional force between 15, is easy to retaining ring 15 being locked on back-up ring 14, further increases stability, needs also exist for sacrificing certain
Set-up time, therefore when taking into account stability and the convenience installed simultaneously, in the external screw thread and retaining ring 15 of the outer wall of back-up ring 14
The pitch of the internal thread of wall is not less than 1.75.
In order to increase the frictional force of the outer wall of retaining ring 15, the outer wall of retaining ring 15 is provided with latch 151.
It the above is only the preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-described embodiment,
All technical schemes belonged under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that for the art
For those of ordinary skill, some improvements and modifications without departing from the principles of the present invention should be regarded as the protection of the present invention
Scope.
