Abstract
The utility model discloses a dust-proof socket jointer, which comprises an insulating body which is provided with a receiving cavity used for receiving several terminals and a dust-proof mechanism. The rear end of the insulating body forms a closed termination, and a guide groove is provided in the inner wall on the two sides of the receiving cavity. The dust-proof mechanism comprises a dust cap and a mechanical spring. The dust cap comprises a baffle, two grab arms, and a position pole. The grab arms are formed by protruding backwardly from the two sides of the baffle. The position pole protrudes backwardly from the back wall of the baffle. The mechanical spring is fixed with the position pole. The grab arms slidingly fits with the guided grooves. An inside stopper is arranged in the front end of the grab arm, thereby enhancing the compression intensity of the grab arms. The stopper gores the closed termination of the insulating body to prevent the dust cap sliding forward while the dust cap slides inside the take-in space, thereby the mechanical spring can recover to the initial statement from compressing deformation.

See also Fig. 4, in concrete enforcement, first, second terminal 31,32 is because of making the existence of plus-minus tolerance, makes the bottom face of the weld part 313 of winning be higher than the bottom face of second weld part 323.The lower surface of the cushion block 26 of insulating body 20 is lower than the lower surface of first, second weld part 313,323 of first, second terminal 31,32,, is lower than second weld part, 323 lower surfaces of second conducting terminal 32 that is.In addition, the lower surface of the cushion block 26 of insulating body 20 also can flush with the lower surface of first, second weld part 313,323 of first, second terminal 31,32, that is, the bottom face of cushion block 26 flushes with the lower surface of second weld part 323 of second terminal 32.
See also Fig. 5, spring 60 is lived 55 sockets with the location of dust cap 50, the grab 54 of clamping hook arm 52 slips into along the guiding groove 22 of insulating body 20, the baffle plate 51 of dust cap 50 is imported in the host cavity 21 by insulating body 20 front ends, promote baffle plate 51 and make grab 54 elasticity be resisted against within the guiding groove 22 wall and further slide backward, slip into the fluting 24 of insulating body 20 rear ends and protrude out out until grab 54 along guiding groove 22.Stop wall 25 can be replaced for grab 54, travels forward to stop dust cap.At this moment, the front end of spring 60 and reference column 55 is replaced in the location hole 231 that is contained in blind end 23.Afterwards, insulating body 20 is imported shells 10 inside, the location that is interlocked, the voussoir 28 corresponding wedge holes 111 of insulating body 20 with shell 10, thus finish the assembling process of the socket connector 1 that the utlity model has dust reduction capability.
The socket connector 1 that the utlity model has dust reduction capability is when cooperating with the plug grafting of butt joint, dust cap 50 is subjected to the promotion of plug and slides backward in the host cavity 21 of insulating body 20, clamping hook arm 52 also thereupon along guiding groove 22 slide backward and all the time elasticity be resisted against guiding groove 22 inwalls.Simultaneously, grab 54 also slides in fluting 24 backward.Spring 60 is contraction distortion gradually under the promotion of dust cap 50.After spring 60 was compressed to a certain degree, at this moment, the rear end of the stopper 53 of dust cap 50 was resisted against the blind end 23 of insulating body 20, and dust cap 50 can not further promote and make spring no longer be compressed.Thereby prevent to cause the compression travel of spring 60 inconsistent after stressed, cause spring 60 excess compression, make the generation that spring 60 is distorted distortion and can't returns back to the initial condition phenomenon because dust cap 50 is one-sided.Stopper 53 is arranged at the inboard of clamping hook arm 52 and also strengthens clamping hook arm 52 outer force bearing strength, thereby prevents that plug is because of the one-sided stressed generation of the phenomenon that clamping hook arm 52 ruptures that makes of unbalance stress.
See also Fig. 6, when terminal 30 welds with the external circuit board, because the bottom face of cushion block 26 is lower than the lower bottom face in first, second weld part 313,323 of first, second terminal 31,32, thereby cushion block 26 contacts also smooth earlier than the bottom surface of first weld part 313 and second weld part 323 with the external circuit board.Because lower surface and the external circuit board of cushion block 25 are smooth, thereby, after first weld part 313 and second weld part 323 and the external circuit board welding, the stress equalization of first weld part 313 and second weld part 323 and the external circuit board, and can not cause the utlity model has the problem that socket connector 1 front end of dust cap upwarps.In concrete enforcement, the height of the cushion block 26 that the rear end of the utility model precipice body 20 is set also can be provided with according to the bottom face of first, second weld part 313,323 of first, second terminal 31,32, flush as bottom face lower in, the bottom face that cushion block 26 can be set and first, second weld part 313,323.
In sum, the generation of the inconsistent phenomenon that is distorted distortion and can't sets back of length of spring compressed stroke that dust cap 50 one-sided stressed backs from causing thereby the stopper 53 that the socket connector 1 that the utlity model has dust-proof mechanism is set up by the clamping hook arm 52 of dust cap 50 prevents, and strengthen the outer force bearing strength of clamping hook arm 52, prevent plug from inserting the back and cause because the generations of the one-sided stressed phenomenon that makes clamping hook arm 52 fractures of clamping hook arm 52, thereby reach better dustproof effect.
In addition, the bottom face that the utlity model has the cushion block 26 that the rear end of insulating body 20 of the socket connector 1 of dust-proof mechanism is provided be lower than first, second terminal 31,32 first, second weld part 313,323 bottom face or flush with lower bottom face in first, second weld part 313,323, make first, second weld part 313,323 and the external circuit board when welding stress equalization, depart from the external circuit board thereby the front end of avoiding the utlity model has the socket connector 1 of dust-proof mechanism tilts to upwarp.
