Abstract
The invention relates to a connector of threaded connection, comprising a plug and a socket, wherein the plug comprises a plug casing, and the outer side of the plug casing is assembled with a coupling nut with internal threads; the socket comprises a socket casing the plug end of which is provided with external threads, the coupling nut is arranged at one side of the plug end of the plug and is provided with stepped holes which are externally large and internally small, staple bolts are arranged in the sections with a larger diameter of the stepped holes, and internal threads are arranged in the sections with a smaller diameter of the stepped holes; the plug end of the plug casing is a stepped shaft, and the external threads of the socket casing are arranged on the sections with a small diameter of the stepped shaft; spiral grooves are arranged on the sections with a large diameter of the stepped shaft; the termination ends of the spiral grooves are provided with location grooves deviating to the external threads; and the plug end of the socket is provided with a plug cavity, and the bottom part of the plug cavity is provided with an elastic piece which is in ejecting-pressing fit with the plug end part of the plug casing correspondingly. The connector has in-place hearing sense, thus avoiding the problem that the plug and the socket are not connected in place due to operation by different operators.
Description
Technical field
The present invention relates to a kind of connector that is threaded, belong to technical field of electric connectors.
Background technology
In the connector that is threaded, its plug needs with coupling nut plug and socket to be fixedly attached to after socket plugs together, and prevents from use to be separated because of reasons such as vibration make plug and socket.The sense of hearing because existing its coupling nut of connector that is threaded does not put in place, when screwing coupling nut, the different differences that occur of strength that the locking degree of coupling nut can be used because of operator's different or same operator, plug and the socket phenomenon that can occur getting loose in use when the attaching nut connected pine; When connecting tension, when plug and socket are separated, be unfavorable for that coupling nut oppositely unscrews on the one hand, connect tension on the other hand and also might cause damage the screw thread in the coupling nut.
Summary of the invention
The purpose of this invention is to provide a kind of connector that is threaded, in order to solve existing its coupling nut of connector that is threaded sense of hearing that do not put in place, the different problems that difference occurs of strength that its tightness can use because of operator's different or same operator when screwing coupling nut.
For achieving the above object, the present invention adopts following technical scheme: a kind of connector that is threaded, comprise plug and socket, and described plug comprises plug casing, the plug casing outside is rotatably equipped with the coupling nut with internal thread; Described socket comprises that inserted terminal has externally threaded Socket casing, the side that described coupling nut is positioned at the plug inserted terminal is provided with the little shoulder hole of outer imperial palace, the big footpath section of this shoulder hole is along being circumferentially with bail, and the internal thread of described coupling nut is arranged at the path section of this shoulder hole; The inserted terminal of described Socket casing is the multidiameter corresponding with described shoulder hole, external screw thread on the described Socket casing is arranged at the path section of this multidiameter, the big footpath section of described multidiameter is provided with the helicla flute with described bail corresponding matching, described spiral fluted clearing end is provided with the externally threaded location notch of deflection, the inserted terminal of described socket is provided with the grafting chamber, and the bottom in this grafting chamber is provided with the elastic component that corresponding roof pressure with the grafting end of plug casing cooperates.
Described location notch is arranged at three crank slots near on the externally threaded cell wall.
Described elastic component is an elastic seal ring.
Described Socket casing and plug casing are the housing of conduction, and the outside conduction of plug casing is connected with the arch ground connection spring that is used for the Socket casing corresponding matching.
Described internal and external screw thread is three-start screw, and described helicla flute is three crank slots, and the pitch of described three crank slots is identical with the pitch of internal and external screw thread.
The outside of described Socket casing is installed with mounting panel.
The connector that the present invention is threaded, be provided with bail in the inserted terminal of the coupling nut on its plug, its Socket casing is provided with the helicla flute with the bail corresponding matching, be provided with the externally threaded location notch of being partial on the Socket casing at the spiral fluted clearing end, simultaneously, bottom in the grafting chamber of socket is provided with the elastic component that cooperates with the inserted terminal roof pressure of plug. and coupling nut is when screwing on Socket casing, in the second half section that coupling nut advances, bail begins to enter helicla flute and moves along helicla flute, when bail arrives the spiral fluted clearing end, the inserted terminal of plug cooperates with the elastic component roof pressure, the micro-backward resilience of coupling nut under the effect of elastic component elastic force, this moment, bail entered in the location notch, because bail is with the coupling nut resilience, when bail enters location notch, bail clashes into mutually with the cell wall of location notch and produces the prompting sound that puts in place, prompting operation person's coupling nut has screwed and has put in place. and connector of the present invention has had the sense of hearing of putting in place, and can send the sound and come prompting operation person's coupling nut to put in place with connection when putting in place, so the tightness that coupling nut is installed can difference not occur because of operator's difference.
It is in screwing process that helicla flute adopts three crank slots identical with the pitch of internal and external screw thread, makes the relative external screw thread of bail and coupling nut have identical progress.
