Description
Technical field
The utility model relates to a kind of plug-type electrical connector plug and plug-type electric connector.
Background technology
Self-locking plug-type electric connector comprises the plug and socket that can realize plugging cooperation, the part correspondence that cooperates at plug, socket is provided with projection and groove, projection on the plug has radial elastic, in the process of plug socket, projection footpath is earlier inwardly received, and plug is inserted into just alignment indentation of a back projection, and projection resets and snaps in the groove, play auto-lock function, prevent that plugs and sockets unexpected disengagement after being subjected to making the axial force of its disengagement from connecting.Based on above-mentioned principle, Chinese patent application 200680001874.2 discloses a kind of plug that is used for the plug-type connector, this plug comprises body and lock tube, on the outer surface of body one end, be provided with annular groove, body portion from annular groove to this end is the anti-delinking part, and the body portion from annular groove to the body other end is the cylindricality connecting portion that is used to install cable; Described lock tube coincide and is sleeved on the outer surface of tube body, lock tube is the little terraced structure of the big end of an end, the big end of lock tube coincide and is sleeved on the body cylindricality connecting portion, and the small end of lock tube coincide and is sleeved on the body annular groove, and the anti-delinking part of body is played and prevented that lock tube axially breaks away from the effect of body; Its circumferencial direction has axial groove at interval in the lock tube upper edge, the groove depth of axial groove extends near big end from small end, axial groove has been divided into several lamellar bodies with the jacket wall of lock tube, make lamellar body possess the radial elastic function, when lamellar body is subjected to radial load, can produce accordingly and move radially, thereby having guaranteed that lock tube its small end part when suit on body can be opened smoothly passes through the body anti-delinking part, can reset in time again after being in place; The end outer surface of each lamellar body on the lock tube (body small end) all is provided with projection radially, and this projection is corresponding with the groove on the complementary socket.The plug of this structure be make its lock tube lamellar body obtain enough big radial elastic and to greatest extent extended lock overlap the groove depth of axial groove, and it is axially to connect that an axial groove is arranged on the lock tube, weakened the intensity of the big end of lock tube on the one hand, the difficulty of processing and the cost of lock tube have been increased, after the identical cover of lock tube installs on the body, outside lock tube, also need install one again and reinforce cover on the other hand.In addition, this plug matches owing to the annular groove on its lock tube and the body partly coincide, between the two without any the space that can allow the lock tube projection receive in when being subjected to radial compression, when plug is connected with socket, projection is the socket endoporus even at the cost of one's life, so that can't peg graft, so this plug can not be realized self-locking plug function with socket.
The utility model content
The purpose of this utility model provides the self-locking plug-type electrical connector plug that a kind of lock tube is easy to process, lock tube intensity is higher.
Another purpose of the present utility model provides the self-locking plug-type electric connector that a kind of lock tube is easy to process, lock tube intensity is higher.
For realizing above-mentioned first purpose, the utility model adopts following technical scheme: self-locking plug-type electrical connector plug, comprise that an end has the body and the stairstepping lock tube that is installed on the body outer ring groove of annular groove, lock tube is equiped with outward reinforces cover, the jacket wall of described lock tube is divided into lamellar body by the axial groove of along the circumferential direction offering at interval, the end outer surface of each lamellar body all has projection radially, lock tube is split type two halves make-up combining structure, axial groove on the lock tube extends to sleeve wall step place by the less end of lock tube, and lock tube fastens and is installed on the corresponding position of body.
The little step surface of big outboard end is held for interior survey in described body annular groove bottom land surface, the lock tube lamellar body coincide with the big end surfaces of annular groove and cooperates, and forms between the little end surfaces of lock tube lamellar body inwall and annular groove in order to hold the annular space of lock tube lamellar body and projection.
For realizing above-mentioned second purpose, the utility model adopts following technical scheme: self-locking plug-type electric connector, comprise self-locking plug-type electrical connector plug and socket, plug comprises that an end has the body and the stairstepping lock tube that is installed on the body outer ring groove of annular groove, lock tube is equiped with outward reinforces cover, the jacket wall of described lock tube is divided into lamellar body by the axial groove of along the circumferential direction offering at interval, the end outer surface of each lamellar body all has projection radially, this projection snaps in the groove that is connected socket on the plug, lock tube is split type two halves make-up combining structure, axial groove on the lock tube extends to sleeve wall step place by the less end of lock tube, and lock tube fastens and is installed on the corresponding position of body.
The little step surface of big outboard end is held for interior survey in the annular groove bottom land surface of described body, the lock tube lamellar body coincide with the big end surfaces of annular groove and cooperates, and forms between the little end surfaces of lock tube lamellar body inwall and annular groove in order to hold the annular space of lock tube lamellar body and projection.
After the utility model is made as split-type structural with lock tube, can adopt the mode of relative fastening to be installed on the body, lock tube is no longer offered very long axial groove for passing through the body anti-delinking part, has shortened groove depth greatly, reduce the difficulty of processing of lock tube, strengthened the intensity of lock tube simultaneously.Change the original smooth surface of body annular groove bottom land into the step surface, behind lock tube on the fastening, formed annular space between lock tube lamellar body inwall and the annular groove bottom land surface, when plug, socket are pegged graft or unplug connection, lock tube lamellar body projection be subjected to after the socket extruding can in receive in the annular space, the lamellar body projection can reset again in resilience after extruding force disappears, and the utility model utilizes the radial elastic performance of lock tube lamellar body and the self-locking plug function that the annular space that can hold the lamellar body projection realizes plug, socket is set under lamellar body.
