Description
Technical field
The present invention relates to electrical connection technical field, in particular it relates to a kind of Fast Installation type plug-in connection.
Background technology
Electric connector is a kind of conventional electric interfaces, and screw thread electric connector is conventional electric connector, and it includes plug
And socket, coupling nut is typically equipped with socket, coupling nut is set on Socket casing Anti-moving vertically, plug
Housing is provided with external screw thread corresponding with the coupling nut, when plug and socket plug together, by described coupling nut with
External screw thread, which coordinates, locks the two, and threaded connection has in itself connects the advantages of steady, intensity is good, but the knot of screw thread itself
Structure defect, in connection procedure, if coupling torque is too small, easily releases automatically, if coupling torque is excessive, easily damage spiral shell
Line tooth form.In addition, the threaded connection set-up time is longer.
The content of the invention
The purpose of the present invention, which is that, provides a kind of Fast Installation type plug-in connection, and the plug-in connection can be connected with socket
It is stable, and installation rate is fast.
Technical scheme is used by the present invention solves the above problems：
Fast Installation type plug-in connection, including plug casing, the plug insulator that is arranged in plug casing and be plugged on
Contact pin on plug insulator；Back-up ring is also arranged with outside plug casing, the back-up ring outer wall front end is provided with snap ring, and rear end is set
There is a connection screw thread, snap ring is coaxial with back-up ring.
As a further improvement on the present invention, the back-up ring outer wall rear end is also arranged with retaining ring, the length of the retaining ring
Degree can be rotated less than length and retaining ring of the connection screw thread on back-up ring axial direction on back-up ring on back-up ring and the axial direction along back-up ring
It is mobile.
As the another improvement of the present invention, the back-up ring is made up of the curved baffle plate split in two cross sections, two gears
The center of circle of plate overlaps and has gap between two baffle plates.
Further, the retaining ring outer wall is provided with latch.
Preferably, the pitch of the connection screw thread is not less than 1.75.
To sum up, the beneficial effects of the invention are as follows：The back-up ring front end of the plug of the present invention is not provided with external screw thread and only sets one
Snap ring, connection screw thread only is set in rear end, during installation, user only needs easily for back-up ring to be pushed into the nut of adapter socket, by card
Ring is caught in the rear end of nut, then plug and adapter socket are relatively rotated into one to two circle, makes the spiral shell of back-up ring rear end and adapter socket
The connection of cap nose threads can securely fix plug and socket.Compared with traditional screw thread coupling, the plug of the present embodiment
Required winding number is few when mounted, therefore not only with socket stable connection, and installation rate is fast.

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：
The plug of the present invention is used cooperatively with the socket with nut.The general knot of socket with nut in the prior art
Structure is as shown in Figure 2：
The socket includes Socket casing 21, nut 22, columned socket insulator 23, and the rear end of nut 22 is with inserting
The front end of seat shell body 21 is connected, and the two is coaxial；Socket insulator 23 is located in Socket casing 21 and nut 22, the socket insulator
Jack 24 is provided with 23, internal thread is provided with the nut 22.
The present invention Fast Installation type plug-in connection structure as shown in figure 1, the plug casing 11 including hollow cylindrical,
The columned plug insulator 12 being arranged in plug casing 11 and the contact pin 13 being plugged on plug insulator 12；Institute's plug
Back-up ring 14 is also arranged with outside housing 11, the outer wall front end of back-up ring 14 is provided with snap ring 141, the outer wall rear end of back-up ring 14 is provided with company
Connect screw thread 16, the outer wall stage casing of back-up ring 14 is smooth and is not provided with any part.Snap ring 141, back-up ring 14, the axle of the three of plug casing 11
Line overlaps, and snap ring 141 is close to the setting of the outer wall of back-up ring 14.Connection screw thread 16 is engaged with the internal thread of the nut 22 of socket；Institute
Stating back-up ring 14 and snap ring 141 can be caught in the nut 22 of socket, when back-up ring 14 is caught in nut 22, connection screw thread 16 and nut
22 threaded connections；The back-up ring 14 is made up of the curved baffle plate split in a manner of recess is relative of two cross sections, two gears
The center of circle of plate overlap and between two baffle plate with gap be baffle plate two relative sides between with gap, two baffle plates
Structure after split is as shown in Figure 1.
In the present embodiment, the front end of back-up ring 14 is not provided with external screw thread and only sets a snap ring 141, and during installation, user only needs
Back-up ring 14 is easily pushed into the nut 22 of socket, snap ring 141 is caught in the two neighboring helix of the screw thread of the rear end of nut 22
Between, by plug（Or nut 22 and socket）One to two circle is rotated further by, the rear end of back-up ring 14 is connected with the nose threads of nut 22
Plug and socket can be securely fixed.Compared with traditional screw thread coupling, the plug-in connection of the present embodiment is required when installing
Winding number（That is turnning circle）Seldom, therefore not only plug and socket stable connection, and installation rate is fast.
Embodiment 2：
On the basis of embodiment 1, also back-up ring 14 is improved as follows in the present embodiment：
