Description
Technical field
The present invention relates to a kind of electric connector, a kind of specifically plug is stable, the round electric connector of steel ball locking easily.
Background technology
Present plug-type round electric connector more and more receives liking of client, and plug-type connector not only plugs rapid and convenient, and the plug space is little; What but now a lot of plug-type electric connectors mostly adopted is that interference fit is locked, and when beginning to plug, contact engaging and separating force meets the GJB requirement; But along with continuous plug; Constantly wearing and tearing in the connector locking place, causes contact engaging and separating force more and more littler after long-term the use, and useful life and mechanical performance are difficult to not reach customer requirement; And electric connector needs the grasping locking cap to carry out the release separation now; In case when emergency taking place need plug electric connector, the position that operating personnel's psychological stress can not quick identification electric connector locking cap can't realize inserting locking fast or extracting release and separate.
The existing patent No. is 201210008205.5 disclosed electric connectors; The steel ball of band spring is set on the Socket casing inwall, and in the plug insertion process, the plug outer wall holds out against in the steel ball withdrawal Socket casing; When plug plug together put in place after; Steel ball extend out to the locking that realizes plug and socket in the groove of plug outer wall in by Socket casing under spring action, though this electric connector can be realized the fast insert-pull of plug and socket, its spring that connects steel ball is prone to inefficacy in plug back repeatedly; Exist the contact engaging and separating force of electric connector to diminish equally, shortcoming such as Practical Performance is not good.
Summary of the invention
To deficiency of the prior art, the invention provides a kind of simple in structurely, it is convenient, stable, accurately to plug, and the anti-plug of plug-pull locking device is used for a long time, contact engaging and separating force no change, the round electric connector of the steel ball locking of long service life.
The technical scheme that the present invention adopts is: a kind of steel ball locking round electric connector, comprise the plug and socket that plugs together each other, and said plug is made up of hole insulation assembly, head capsule body, plug casing; Insulation assembly one end in hole is arranged at the head capsule intracoelomic cavity; The external plug casing that is socketed with of head capsule, cable passes plug casing and is connected in the hole insulation assembly other end, and said socket is made up of pin insulation assembly and seat housing; Pin insulation assembly one end is arranged in the housing; Cable passes a housing and connects the pin insulation assembly other end, it is characterized in that the inwall of said plug casing mating side is provided with the steel bead groove that a circle is provided with along the plug casing circumferencial direction, and the shell wall of said seat housing mating side is provided with the steel ball hole of running through shell wall more than one; The steel ball hole site is corresponding in steel bead groove; The inside and outside aperture that shell wall is run through in the steel ball hole is the closing in shape, and a steel ball is arranged at and is activity in the steel ball hole and is rolled into inside and outside aperture and closes up and be limited to steel ball hole internal state, and diameter of the steel ball is greater than the shell thickness of seat housing mating side.
Said plug casing comprises locking cap, ripple spring and plug attachment cap; Locking cap is connected on the head capsule body through the ripple spring housing; Locking cap is the state that is connected on the head capsule body that compresses through plug attachment cap screw thread rotary joint housing, and cable passes the hole insulation assembly in the plug attachment cap connector housing.
The non-mating side of said seat housing is through the screw thread socket attachment cap that spins, and cable passes the pin insulation assembly in the socket attachment cap Connection Block housing.
The housing outer wall of said head capsule body mating side be provided with one along the head capsule axon to the positioning spline that is provided with, the inner walls of seat housing mating side is provided with one and is the corresponding positioning key that plugs together state with positioning spline.
The inner walls of said seat housing mating side is provided with the sealing ring that all is sealed and matched with hole insulation assembly, pin insulation assembly.
Said plug attachment cap is provided with plug sealing hole, is plug encapsulating district in the plug attachment cap.
Said socket attachment cap is provided with socket sealing hole, is socket encapsulating district in the socket attachment cap.
Adopt above technical scheme; The beneficial effect that the present invention reaches is: when plug, when socket plugs together; Through the corresponding head capsule body of seat housing positioning key positioning spline location, be convenient to plugging together fast of electric connector, plug together accurate positioning; Wherein the ripple spring is more even than general spring stress in the plug, the stressed optimum state that reaches when making this electric connector push-and-pull plug; Slidably, when housing plugged together housing right overhead, the outer wall of head capsule body outwards held out against steel ball to steel ball on the seat housing shell wall in the steel ball hole; Because diameter of the steel ball is greater than seat housing shell thickness; The inside and outside closing in steel ball hole makes steel ball not deviate from the steel ball hole, and outer wall and steel ball outer end that this moment, steel ball the inner held out against the head capsule body exceed the steel ball hole and cooperate the location with locking cap inwall steel bead groove, the locking that is connected of realization head capsule body and a housing; Steel ball need not be realized locking function by servicing units such as springs; The steel ball anti-wear performance is good, repeatedly after the plug locking positioning, contact engaging and separating force is not all being had influence, guarantees higher stability in use and long useful life; In addition; Pour into sealing by sealing hole on the attachment cap of plug, socket to its internal cavity; Make to seal between insulator in it, cable and the attachment cap three and closely be connected; Strengthened the stationarity of core of a cable, in case of emergency can directly pass through cable drawing plug, socket, need not discern the electric connector locked position and can accomplish the quick release separation.
The present invention controls the flexible structure medi-spring deletion that realizes electric connector locking of steel ball with conventional springs; And the steel ball of diameter greater than steel ball hole hole depth be constrained in the steel ball hole of inner/outer hole batter, the face that the plugs together extruding steel ball that utilizes head, seat to plug together makes steel ball sliding extension in the steel ball hole realize that the positioning and locking of plug and socket separates with release; It is simple in structure, compact; It is convenient, stable, accurately to plug, and it is constant to plug contact engaging and separating force for a long time, long service life.
