Abstract
The utility model relates to a plug containing an anti-loosening connecting nut and a connector assembly. The plug containing an anti-loosening connecting nut comprises a tubular plug body. A connecting nut coaxial with the plug body is rotatably sleeved on the plug body. A circular inner groove is coaxially arranged on the inner wall surface of the connecting nut, while an outer groove corresponding to the inner groove is coaxially arranged on the outer wall surface of the plug body. A steel ball is filled in space surrounded by the inner and outer grooves and rolledly matched with the bottom surfaces of the inner and outer grooves. When an axial pulling force is applied to the plug body in using process, the steel ball has an effect of bond in order to snap the connecting nut onto the plug body so as to prevent the two from loosening. Compared with conventional fixing form using a clip spring, the plug substantially enhances anti-loosening performance of the connecting nut and the plug body.
Description
Technical field
The utility model relates to and is electrically connected annex, especially a kind of plug and connector assembly with anticreep coupling nut.
Background technology
In electric connector field; The locking mechanism that is threaded is widely used between the plug and socket; Generally be the sheathed coupling nut of coaxial rotation on the plug casing of plug, on Socket casing, be arranged at the corresponding external screw thread of said coupling nut, cooperate through the jump ring anticreep in the axial direction between said coupling nut and the plug casing; When plug after socket is plugged on; Through being spirally connected between the external screw thread on said coupling nut and the Socket casing plug and socket is locked together, thereby guarantee reliable connection the between plug and the socket, then useless in the axial direction between plug casing and the Socket casing itself in the maintenance structure that prevents that the two from getting loose.Yet, need plug together the back at plug and socket and keep bearing great pulling force between the plug and socket, in such cases at some special occasions; The coupling nut that above-mentioned employing jump ring anticreep cooperates with the plug casing anticreep then can't meet the demands, and specifically, promptly the confining force of jump ring is limited; When bigger tension is on coupling nut, then very likely causes the distortion of jump ring, and then make coupling nut from plug casing, come off vertically; This kind situation is in case take place; Then directly can cause the inefficacy that is connected between plug and the socket, especially when being applied to fields such as space flight, even can bring the consequence that to envision; In addition; The coupling nut that cooperates with the plug casing anticreep through jump ring tends to when rotating with respect to plug casing because jump ring and the frictional force generation catching phenomenon between it; Especially when coupling nut is about to spinning and puts in place with respect to socket, the frictional resistance between itself and the jump ring sharply increases, and very easily causes the generation of the problem that spinning between coupling nut and the socket is not in place; Thereby cause the virtual connection between plug contact and the socket contact, influence the transmission quality of the two.
Summary of the invention
The purpose of the utility model is to provide a kind of plug with anticreep coupling nut, is prone to the problem that from plug casing, is pulled vertically with the coupling nut that solves existing plug.
Simultaneously, the purpose of the utility model also is to provide a kind of electric coupler component, is prone to the problem that from plug casing, pulled vertically to solve coupling nut on its plug.
In order to address the above problem; The plug with anticreep coupling nut of the utility model adopts following technical scheme: the plug with anticreep coupling nut; The plug casing that comprises tubular; Turning set is provided with coaxial with it coupling nut on the said plug casing, is coaxially arranged with the inside groove of annular on the internal face of said coupling nut, coaxial being provided with and the water jacket relative with said inside groove on the outside wall surface of plug casing; Fill out in the space that surrounds of said inside and outside groove and be provided with steel ball, said steel ball rolls respectively with the groove bottom of inside and outside groove and cooperates.
Said steel ball is filled in the space that inside and outside groove surrounds from the through hole that coupling nut is provided with, and coupling nut is covered with cover plate in said through hole.
Said through hole is the little stepped hole of outer imperial palace, and said cover plate is installed between the step surface that forms between the large and small footpath section of jump ring and stepped hole in the big footpath section that is located at stepped hole.
Offer inside and outside penetrating oil filler point on the said cover plate.
Said coupling nut in its week upwards screw fit pin is arranged, said pin in an end of plug casing extends to the annular slot on the coaxial outside wall surface that is opened in plug casing and with spacing cooperation of two cell walls of draw-in groove.
The electric coupler component of the utility model adopts following technical scheme: a kind of electric coupler component; Comprise plug and socket, plug comprises the plug casing of tubular, and turning set is provided with coaxial with it coupling nut on the said plug casing; Socket has Socket casing; Have the external screw thread corresponding on the Socket casing, be coaxially arranged with the inside groove of annular on the internal face of said coupling nut, coaxial being provided with and the water jacket relative on the outside wall surface of plug casing with said inside groove with said coupling nut; Fill out in the space that surrounds of said inside and outside groove and be provided with steel ball, said steel ball rolls respectively with the groove bottom of inside and outside groove and cooperates.
Said steel ball is filled in the space that inside and outside groove surrounds from the through hole that coupling nut is provided with, and coupling nut is covered with cover plate in said through hole.
Said through hole is the little stepped hole of outer imperial palace, and said cover plate is installed between the step surface that forms between the large and small footpath section of jump ring and stepped hole in the big footpath section that is located at stepped hole.
Offer inside and outside penetrating oil filler point on the said cover plate.
Said coupling nut in its week upwards screw fit pin is arranged, said pin in an end of plug casing extends to the annular slot on the coaxial outside wall surface that is opened in plug casing and with spacing cooperation of two cell walls of draw-in groove.
Because the plug with anticreep coupling nut of the utility model is coaxially arranged with the inside groove of annular on the internal face of its coupling nut; Coaxial be provided with and on the outside wall surface of its plug casing in the relative water jacket of said inside groove; Fill out in the space that surrounds of said inside and outside groove and be provided with steel ball, said steel ball and the groove bottom of inside and outside groove roll respectively cooperate and with the wall face matched in clearance of inside and outside groove; Therefore; In use when plug casing receives axial pulling force; Thereby said steel ball can play the effect of key coupling nut and plug casing are connected together; Prevent that the two from getting loose,, improved the anti-loose performance between coupling nut and the plug casing greatly than existing jump ring fixed form; In addition; Said steel ball makes simultaneously and constitutes bearing arrangement between coupling nut and the plug casing that coupling nut constitutes the outer ring of bearing arrangement, the inner ring of plug casing formation bearing arrangement; The wall of inside and outside groove constitutes the retainer of bearing arrangement; Thereby the resistance when reducing coupling nut and rotating with respect to plug casing makes coupling nut stressed evenly, has solved spinning problem not in place between coupling nut and the socket.
