Abstract
A concentric circular rotary cable plug belongs to the field of dynamo-electric technique, mainly solving the encapsulation problem of plug. The utility model has the technical characteristic that a pin and a jack are arranged in a concentric circular manner and the two can relatively rotate under the circumstance that the pin can insert in the jack. When the plug butt-joints a rotary box joint shell 4 and a pin joint shell 6, a male buckle 11of pin joint terminal 6 can switch-in a female buckle 10 of box joint terminal 4. Through upper buckle pressing an O-shaped sealing ring 5 on the plug end-face, a thread 10 and 11 of the plug are connected with the pin and jack for conduction which are encapsulated in the sealed cavity formed by the box joint shell 4, the O-shaped sealing ring 5and the pin joint shell 6, thereby realizing encapsulation function of the plug.
Description
Technical field: the utility model relates to a kind of electromechanical industries that are applied to can be at the concentric circles rotary cable plug of long-term safety use under the adverse circumstances.
Background technology: in the interim in the open at present process of constructing; often the multicore cable plug be to use and stube cable and electrical appliance come; but regular meeting's sand that rains, blows when working in the open; also can use some in the production to the disadvantageous material of plug; as water, wet goods; plug environmental condition in use is abominable; frequent poor sealing (what have can not seal at all) because of cable plug; causing into, materials such as water, oil, salt, alkali cause fault; give work and produce generation and come inconvenience, even bring great security incident.Present cable plug, pin and jack show triangle or polygon, method of attachment is that the pin of plug is inserted in the jack of socket, screw thread screw thread outside tightening is then strained joint and is compressed female root one sealing ring of Luo and seals, the plug sealing of Lian Jieing is poor like this, the screw thread screw thread contacts with the medium of plug environment of living in again, sometimes because of needing to dial cable plug down in the use, but because of environment for use badly causes joint screw thread thread gluing (the burning corrosion causes) sometimes, need push aside when connecting and but dial not open, above drawback at existing plug, produce the design that changes the existing cable plug from structure, designed the utility model: concentric circles rotary cable plug.
Summary of the invention: problem to be solved in the utility model is: the sealing problem of plug.
The utility model is achieved in that the arrangement mode of pin and jack adopts concentric circles, see that the Fig. 1 in the Figure of description is the crosscut profile of the utility model embodiment three-prong plug, three solid line concentric circless are represented three jacks in the concentric circles cable plug among the figure, and three dotted line concentric circless are represented three pins of concentric circles cable plug.Cylindrical shape pin and jack are made by conduction and insulating material combination, and with regard to one group of pin and jack, their electric conductors that inserts back pin and jack that is complementary contact, and are insulators at two skins that contact electric conductors.
Because jack and pin have adopted concentric circles of the present utility model to arrange, the concentric circles cable plug can rotated with the jack end relatively to plugging the back plug end, shown in Figure 2 as Figure of description, at the arbitrary end of plug to rotary connector after plugging, the screw thread 10 and 11 that is used among Fig. 2 connecting is buckled on the process of plug rotation, compress the O-ring seals that is installed in the plug end, realize the sealing function of plug.The screw thread of attachment plug is in the seal area of plug, the concentric circles cylindrical shape pin and the insertion hole groups that are used for connection cable are in the seal area of plug after plug rotation butt joint, and the present pin of the sealing of concentric circles rotary cable plug and environmental suitability is that the plug of triangle or polygon arrangement is good.
Description of drawings: the utility model is further specified below in conjunction with drawings and Examples.
Fig. 1 is the crosscut profile of the utility model embodiment.
Among the figure 1: link the concavo-convex key of fixing with shell with core circle rotary cable plug inner core; 2: three groups of actual situation loop lines are represented three groups of concentric circles cylindrical shape pins and the jack of embodiment, and electric conductor of each group pin and jack is conducting, and group insulate with electric conductor between organizing; 3: the groove on the plug body end face is used to install O-ring seals.
Fig. 2 is a structure chart of the present utility model.
Among the figure 4: the female joint shell; 5:O shape sealing ring; 6: the male joint shell; 7: cable; 8: the inner key cylinder screw; 9: the protruding key of inner core; 10: the female screw thread; 11: the male screw thread; 12: cable and joint shell gap, filled the sealing and the material of fixation.
Embodiment: as Fig. 1, shown in 2, produce concentric circles cylindrical core pin and jack 2 and plug body 4 earlier, 6, cable 7 is passed plug body 4,6, cable conductor is connected on the corresponding wiring village, aiming at inner core and shell then links fixing concavo-convex key 1 and is respectively charged into separately shell, with inner key cylinder screw 8 locking inner cores, filled material fixing and sealing function at cable and 12 places, joint shell gap, put O-ring seals 5 in the groove 3 on the plug body end face, banjo will be gone into the O-ring seals 5 that female screw thread 10 compresses the shell end at last in 11 rotations of male screw thread then.
Claims (4)
1, concentric circles rotary cable plug is characterized in that: the arrangement mode of its jack and pin adopts concentric circles.With regard to one group of cylindrical shape pin and jack, their electric conductors that inserts back pin and jack that is complementary contacts, are insulators at two skins that contact electric conductors.
2, concentric circles rotary cable plug according to claim 1 is characterized in that: concentric circles cylindrical shape pin and insertion hole groups number be 1 at the most the group.
