[embodiment]

See also Fig. 1 and Fig. 7, the utility model electric connector 1 is used to electrically connect flexible PCB (not shown), comprises insulating body 2, gland 3, the conducting terminal 4 that is contained in insulating body 2 that can cooperate with insulating body 2 rotations and the metal ear 5 that is embedded at insulating body 2 two ends.

Insulating body 2 comprises longitudinal resettlement section 22, the carrier 24 that 22 1 sides vertically extend from the resettlement section and the fixing arm 26 that 22 two ends vertically extend from the resettlement section respectively.Wherein resettlement section 22 includes front surface 222, is opened in the plurality of conductive terminals groove 224 on this front surface 222 and is darted at some arc bumps 226 of 224 of adjacent two conducting end pilot trench apart from one another by ground.Some grooves 244 parallel to each other that carrier 24 includes upper surface 242 and corresponding conducting end pilot trench 224 positions are arranged with formation on upper surface 242.Fixing arm 26 comprises the holding tank 262 that is opened in insulating body 2 both ends and is arranged with the slideway 264 that forms and be provided with block 2642 in the appropriate location in these two holding tanks, 262 lateral surfaces.

Please in conjunction with consulting Fig. 2, gland 3 includes lengthwise flat-platy base portion 32 and is located at the arm 34 at these base portion 32 two ends respectively.Wherein base portion 32 comprises being opened in the groove 322 that the one lateral edge matches with arc bump 226 on the insulating body 2 and being located at its another side and is used for the bearing surface 324 that connects with flexible PCB.Arm 34 can be contained in the holding tank 262 of insulating body 2, and in its relative lengthwise to both ends of the surface stretch out and be provided with a pivot 342, this pivot 342 can be stuck on the block 2642 on the slideway 264 at insulating body 2 two ends, thereby gland 3 is positioned on the insulating body 2, prevents to break away from insulating body 2 in gland 3 rotary courses.

Conducting terminal 4 comprises holding parts 42 in the conducting end pilot trench 224 that is immobilizated in insulating body 2, be placed in the groove 244 of insulating body 2 docking section 44 that can be electrically conducted with flexible PCB and the weld part 46 in order to be soldered to circuit board, and wherein holding parts and docking section roughly are oppositely arranged.

Metal ear 5 is embedded at the both sides of insulating body 2, is used to be soldered to circuit board, to strengthen electric connector 1 and circuit board connection stability.

See also Fig. 1, Fig. 3, Fig. 4 and Fig. 7, during electric connector 1 assembling, elder generation packs conducting terminal 4 correspondences in the insulating body 2, this moment, the holding parts 42 of conducting terminal 4 was immobilizated in the conducting end pilot trench 224 of insulating body 2, and docking section 44 is placed in the groove 244 of insulating body 2 and protrudes in upper surface 242.This holding parts 42 exposes the appearance profile of the appearance profile of conducting end pilot trench 224 parts less than the arc bump 226 of insulating body 2 simultaneously, does not contact with the holding parts 42 of conducting terminal 4 when guaranteeing that gland 3 is the center rotation with the center of circle of arc bump 226.And, after conducting terminal is installed, docking section 44 is with respect to the resettlement section of the close more insulating body 2 in arc bump 226 centers of circle, then with gland 3 with the fashion of extrusion insulating body 2 of packing into, at this moment, arm 34 ends of gland 3 are corresponding to holding tank 262 positions of insulating body 2, its pivot 342 enters in the slideway 264 of insulating body 2 and is stuck in block 2642 places with fashion of extrusion, thereby the relative position of stationary gland 3 and insulating body 2, make gland 3 can be stably be the center with the arc bump 226 of insulating body 2, between enable possition and make position, rotate.

See also Fig. 1, Fig. 5 and Fig. 6, during use, earlier gland 3 is placed the enable possition, insert flexible PCB, rotate gland 3 then, making its arc bump 226 with insulating body 2 is that pivot rotates to make position, at this moment, the bearing surface 324 of gland 3 is connected to flexible PCB, makes flexible PCB be connected to upper surface 242, and the docking section 44 that will expose the conducting terminal 4 of upper surface 242 is pressed into groove 244, thereby realizes the stable electric connection of flexible PCB and conducting terminal 4.And since the profile profile of arc bump 226 greater than the holding parts 42 profile profiles of conducting terminal 4, so do not contact in gland 3 rotary courses with conducting terminal 4, when gland 3 rotates to make position, gland 3 just can contact with conducting terminal 4, utilizes conducting terminal 4 and 2 pairs of flexible PCBs of insulating body that strong support force is provided.Thereby can prevent conducting terminal 4 stress deformation or be separated in gland 3 rotary courses, guarantee 4 stable electric connections of conducting terminal of flexible PCB and electric connector 1 with insulating body 2.

See also Fig. 6, when flexible PCB inserts, the docking section 44 of conducting terminal 4 is connected to flexible PCB, give flexible PCB one pressure, this pressure acts on the bearing surface 324 of gland 3 by flexible PCB, and since the application point A of this pressure on horizontal direction with respect to the resettlement section 22 of the more close insulating body 2 of the rotating shaft of gland 3, and after gland 3 is rotating closed, the pressure that this conducting terminal 4 acts on the bearing surface 324 of gland 3 is to fasten direction in the same way with gland 3 to the gland 3 moment direction M that produces, therefore have self-locking effect after gland 3 is rotating closed, gland 3 can not opened voluntarily because of the effect of conducting terminal pressure.
