Referring to FIG. 4 at the same time, the front guide tube ι8 is disposed at one end of the accommodating groove 丨丨 near the insertion hole 12, and is disposed on the outer surface of the cam 15 through the circular through hole 183 for providing a movement for the cam 15. track. A shaft hole 186 parallel to the height direction of the insulator is disposed on each of the two side walls of the left and right interlayers 182, 185 of the leading cylinder 18. The longer length of the pair of switch terminals 23, 24 away from the wheel 16 is placed in the left and right sandwich layers 184, 185 of the front guide tube 18, respectively. 'The fixed shafts 23', 24' disposed thereon pass through the left side of the front guide tube 18. a shaft hole 186 provided on the two side walls of the right interlayer 184, 185 and the 099118635 Form No. A0101 Page 8 of 23 0992032988-0 201145719 Turning of the switch terminals 23, 24, thereby the pair of switch terminals 23, 24 One end away from the runner 16 is fixed in the left and right interlayers 184, 185 of the leading cylinder 18. [0020] 后 The rear guide tube 19 is disposed adjacent to the front guide tube 18 and away from the insertion hole 12, which is placed on the outer surface of the runner 16 through a circular through hole 193 for providing a rotation for the rotation of the wheel 16. track. A shaft hole 196 parallel to the width direction of the insulator 10 is disposed on each of the side walls of the upper and lower interlayers 191, 192 of the rear guide tube 19, respectively. One end of the pair of shorter-length switch terminals 21, 22 near the runner 16 is placed in the upper and lower interlayers 191, 192 of the rear guide cylinder 19, respectively, and the fixed shafts 21', 22' provided thereon pass through the rear guide cylinder 19 a shaft hole 196 provided on both side walls of the upper and lower interlayers 191, 192 and a turn of the pair of switch terminals 21, 22, thereby moving the two shorter length switch terminals 21, 22 away from one end of the wheel 16 It is fixed in the upper and lower interlayers 191, 192 of the rear guide tube 19. [0021] Please also refer to FIG. 5, when the audio jack connector 1 is mounted, the cam 15 is firstly engaged with the reel 16, and the elastic member 172 at the base 17 is connected to the cam 15 away from the plug. One end of the through hole 12 and the other end are connected to the fixing portion 171. Next, the front guide tube 18 is sleeved on the outer surface of the cam 15, the rear guide tube 19 is sleeved on the outer surface of the runner 16, and the two ends of the pair of switch terminals 21, 22, 23, 24 are placed away from the cam 15 respectively. In the long slot 162 of the runner 16, at the same time, the pair of switch terminals 23, 24 having a longer length are placed opposite to the left and right interlayers of the front guide cylinder 18 and the rear guide cylinder 19, and the fixed shafts of the pair of switch terminals are fixed. 23', 24' pass through the shaft holes 186 of the two side walls of the left and right interlayers 184, 185 of the leading cylinder 18 and the turns of the switch terminals 23, 24, thereby fixing the two switch terminals 23, 24 to the left , right folder 099118635 Form number Α 0101 Page 9 / Total 23 page 0992032988-0 201145719 Layer 184, 185. A pair of shorter lengths of the switch terminals 21, 22 are placed opposite to the upper and lower interlayers of the front and rear guide tubes 18, 19, and the fixed axes 21', 22' of the pair of switch terminals 21, 22 are passed through the rear guide. a shaft hole 196 of the two side walls of the upper and lower interlayers 191, 192 of the cylinder 19 and a turn of the switch terminals 21, 22, thereby fixing the two shorter length switch terminals 21, 22 to the upper and lower interlayers 191, 192. Finally, the insulator 1 is mounted on the front guide cylinder 18, the rear guide cylinder 19 and the base portion 17 by means of two semi-rectangle covers, and the upper, lower, left and right sides of the front guide cylinder 18 and the rear guide cylinder 19 are sandwiched. The two side walls respectively penetrate the four penetration holes 1 〇i , 102 , 103 , 104 of the insulator 1 , thereby fixing the front guide tube 18 and the rear guide tube 19 in the insulator 10 , One end is connected: the cylinder 26 and the other end connected to the front guide cylinder 18 to elastically place the pick-up raft 26 in the circular opening 13 of the insulator 10. [0022] Please refer to FIG. 6 to FIG. 7 simultaneously. When the plug 2 is inserted, the plug 2 is first inserted into the receiving slot 11 of the insulator 1 through the insertion hole 12 until the plug 2 contacts the cam. The groove of 15 continues to apply a force to the plug 2 to urge the cam 15 to move in a direction away from the insertion hole 12, the tongue 151 of the cam 15 interacting with the chute 161 of the runner 16, thereby The rotating wheel 16 is driven to start to rotate along the rear guide tube 19 such that one end of the two pairs of switch terminals 21, 22, 23, 24 away from the cam 15 relatively moves from the inside of the long groove 16 2 to the protruding portion 16 3 , According to the principle of the f-bar, when the positions of the two pairs of switch terminals 21, 22, 23, 24 are far from the end 15 of the cam, the position of the other end is relatively lowered, thereby causing the two pairs of switch terminals 21 ' 22, 23 24 is close to the end of the cam 15, so that the plug 2 is fixed in the % edge body 1 ,, while the two pairs of switch terminals 21, 2 2 099118635 Form No. A0101 Page 10 / Total 23 Page 0992032988-0 201145719 23 The contact on the 24 and the conductive portion on the plug 2 are electrically connected. In the first 2, since the cylinder 26 in which the insertion hole 12 is located is movable, the user can continue to apply a force to cause the plug 2 to press the cylinder 26 to continue to be inserted inwardly, at which time the two pairs of switch terminals 21, 22, 23, 24 is further moved from the protruding portion 163 to the long groove 162, and the two pairs of switch terminals 21, 22, 23, 24 are relatively opened according to the principle of the lever, thereby releasing the fixing effect on the plug 2, The user can dial the plug 2° and compress the elastic member 172 ' during the movement of the cam 15 away from the insertion hole 12, and during the insertion of the plug 2, the elastic member 172 is elastically restored to drive the cam 15 again. Go back to the original location.
