[embodiment]

See also Figure 1 and Figure 2, the utility model electric connector is in order to (the camera module only is a schematic diagram with camera module 3, do not show concrete structure) be fixed on the circuit board 4 with through hole 40, and making camera module 3 by the electronic component transmission of electric signals, electronic component is a flexible printed circuit board 5 in the present embodiment.

See also Fig. 3, Fig. 4 and shown in Figure 5, for convenient narration is called first side 41 with the side that circuit board 4 has welding gasket, the opposite side relative with first side 41 is called second side 42, and described through hole 40 runs through the both sides of circuit board.The utility model electric connector comprises first housing 1, second housing 2 and is placed in flexible printed circuit board 5 in second housing 2, first housing 1 is to be bent to form by the sheet metal punching press, it comprises four sidewalls facing each other, be called the first side wall 11, second sidewall 12, the 3rd sidewall 13 and the 4th sidewall 14, these four sidewalls surround the receiving space 10 of a both ends open, wherein the first side wall 11 is relative with second sidewall 12, and the 3rd sidewall 13 is relative with the 4th sidewall 14.The root edge of the first side wall 11 and second sidewall 12 is equipped with a pair of in order to be welded in the weld part 15 on circuit board first side 41, the inboard of first and second sidewall weld part 15 is equipped with two first buckling partss 16, and this first buckling parts 16 is the projectioies that protrude out outside receiving space 10 from sidewall.The 3rd sidewall 13 and the 4th sidewall 14 are provided with a pair of groove 17.

Second housing 2 is bent to form for the sheet metal punching press, it has diapire 20, second housing 2 can be assembled on first housing 1 (being detailed later), described diapire 20 has four sides facing each other, be called first side 21, second side 22, the 3rd side 23 and four side 24, these four sides respectively corresponding first housings 1 the first, second, third and the 4th sidewall.First side 21 and second side 22 are equipped with upwardly extending a pair of second buckling parts 25, and each second buckling parts 25 is provided with buckling groove 250.The outside of second buckling parts 25 of first side 21 and second side 22 is provided with the upwards shell fragment 26 of bending.The 3rd side 23 and four side 24 are equipped with upwardly extending holding parts 27, and each holding parts 27 is provided with elasticity retaining sheet 271.Diapire 20 is provided with the pressure contact portion 28 that is upturned.

See also shown in Figure 5ly, the weld part 15 of first housing 1 is welded on first side 41 of circuit board 4, and the through hole 40 of circuit board 4 is relative with the opening of the receiving space 10 of first housing 1, and can hold second housing 2 and camera module 3 passes through.See also shown in Figure 4, flexible printed circuit board 5 is installed on the top of second housing, 2 diapires 20 and is positioned at receiving space 10, camera module 4 is installed in the top of flexible printed circuit board 5, pressure contact portion 28 on the diapire 20 compresses flexible printed circuit board 5, and flexible printed circuit board 5 is electrically contacted with the camera module.Retaining sheet 271 on second housing 2 matches with draw-in groove 30 on the camera module 3 and makes second housing 2 and camera module 3 fixing mutually.Second housing 2, flexible printed circuit board 5 and camera module 3 after the assembling upwards is assembled in the through hole 40 from second side 42 of circuit board 4, see also Fig. 1 and Fig. 2, second buckling parts 25 protrudes out to first side of circuit board 4 through through hole 40 and is interlocked with first buckling parts 16, and promptly the buckling groove 250 on second buckling parts 25 and first buckling parts 16 are interlocked.The shell fragment 26 of second housing 2 was connected on second side 42 of circuit board 4 and prevented that second housing 2 from further moving up this moment, the second, the cooperation of second buckling parts prevents that second housing 2 from moving down, and therefore second housing 2 can closely be located with first housing 1 and be cooperated.After the assembling, the holding parts 27 of second housing 2 is contained in the groove 17 of first housing 1, is equipped with the pressure section 18 that compresses mutually with camera module 3 on each sidewall of first housing 1, therefore,
