Abstract
The utility model discloses a clamping mechanism of a thread screwing wire, which comprises a casing and a tail threaded sleeve, wherein the tail end of the casing is connected with the tail threaded sleeve through threads. An inner wall of the middle of the tail threaded sleeve is of a inclined plane structure, the wire of a connector is installed in the casing and provided with a rubber ring and an elastic clamping head, and the elastic clamping head is provided with a groove in an elastic claw structure. The clamping mechanism of the thread screwing wire is of a round thin-wall structure, and the contour dimension of the clamping mechanism is smaller than that of a connector body, thereby being favorable for miniaturization development of the round connector. Simultaneously, the clamping mechanism of a wire bundle is in a composite clamping mode of the elastic claw and the rubber ring, and clamping reliability is high. Besides, the coating form of the rubber ring enables a sealing separation layer to be formed, the effect of sealing the wire is achieved, and the wire bundle is clamped by means of deformation of the elastic clamping head itself and the rubber ring. The clamping mechanism of the thread screwing wire solves the technical problem that in the prior art, the contour dimension of a wire bundle clamping portion is large.
Description
Technical field the utility model belongs to technical field of electric connectors, relates to a kind of screw thread and screws the lead clamp system.
Background technology is present; The processing of cylindrical connector tail end wire harness; The general wire clamp that adopts screws clamping through screw, nut; This processing mode need be reserved enough screws, the installing space of nut, must cause wire harness retained part overall dimension big, is unfavorable for the microminiaturization development of cylindrical connector.
The purpose of summary of the invention the utility model is to solve prior art to have the big technical problem of wire harness retained part overall dimension, provides a kind of screw thread to screw the lead clamp system, to overcome the deficiency of prior art.
The utility model screw thread screws the lead clamp system, comprises shell and afterbody swivel nut, and the tail end of said shell and afterbody swivel nut are through being threaded; The middle part inwall of said afterbody swivel nut is ramp structure, connector mounted lead in the said shell, and lead has been provided with rubber ring and collet; Fluting is the elastic claw structure on the said collet, and when receiving the external force extruding, collet can draw in; When wanting clamping wire, tighten the afterbody swivel nut earlier, the interior inclined-plane of afterbody swivel nut applies active force to the fluting hollows of collet; This power not only makes collet draw in and compresses lead; And the extruding collet compressing rubber circle that moves forward, tighten the afterbody swivel nut, collet more can clamping wire; The rubber ring distortion is big more, realizes the function of firm grip lead.
Therefore the rounded thin-wall construction of the utility model, overall dimension are beneficial to the microminiaturization development of cylindrical connector less than the overall dimension of connector body.Simultaneously; The clamp system of wire harness is the compound tighten mode of elastic claw and rubber ring, and the reliability of clamping is high, and the coating form of rubber ring can form the sealing insulating course; Play the effect of sealed guide, wire harness leans on the distortion of collet self and rubber ring to clamp.The utility model has solved prior art and has had the big technical problem of wire harness retained part overall dimension.
Description of drawings Fig. 1 is the utility model master sectional structure sketch map;
Fig. 2 is the elastic claw three-dimensional structure sketch map of the utility model clamp system.
Among the figure: 1. shell 2. rubber rings 3. collets 4. afterbody swivel nuts 5. leads
Embodiment sees figures.1.and.2, and the utility model screw thread screws the lead clamp system, comprises shell 1 and afterbody swivel nut 4, and the tail end of said shell 1 and afterbody swivel nut 4 are through being threaded; The middle part inwall of said afterbody swivel nut 4 is ramp structure, and connector mounted lead 5 in the said shell 1, lead 5 have been provided with rubber ring 2 and collet 3; Fluting is the elastic claw structure on the said collet 3.
Among Fig. 1, the tail end of shell 1 is a helicitic texture, is used for and being connected of afterbody swivel nut 4; The connector mounted lead 5 in the inside of shell 1 is with rubber ring 2, collet 3 on the lead 5; Collet 3 is a notching construction, and when receiving the external force extruding, collet 3 can draw in.When wanting clamping wire 5, tighten afterbody swivel nut 4 earlier, the interior inclined-plane of afterbody swivel nut 4 applies active force to the fluting hollows of collet 3, and this power not only makes collet 3 draw in and compresses lead 3, and the extruding collet 3 compressing rubber circle 2 that moves forward; Therefore, tighten afterbody swivel nut 4, collet is the ability clamping wire more, and rubber ring 2 distortion are big more, has realized the function of mechanism's reliable grip lead 5.
Among Fig. 2, the elastic claw that collet 3 compresses lead can form the pincers of mutual interlock and go into power, guarantees the reliable grip lead, prevents that lead is loosening.The inclined-plane that collet 3 contacts with the afterbody swivel nut is an arc surface, and arc surface has the smooth characteristic that is difficult for jam, and assurance afterbody swivel nut screws in the compaction process and is not stuck; The protruding key in the location of collet 3 then is and the groove fit of shell 1 tail end, prevents to tighten in the afterbody swivel nut process, and collet and then rotation skids.It is thus clear that the design feature of collet 3 has guaranteed the reliability of clamp system clamping lead.
The utility model screw thread screws the lead clamp system, is the afterbody swivel nut through screwing mechanism, makes the inclined-plane of swivel nut compress the collet of fluting, and the fluting of collet is drawn in gradually, and oral area diminishes, thereby compresses the insulating barrier of lead, prevents that lead from getting loose.Simultaneously, in compressing the process of elastic claw, the power of elastic claw is applied to again on the rubber ring, rubber ring since the shell step stop generation crimp, tightly wrap lead, thereby realize that secondary clamps.
