Embodiment

By describing technology contents of the present utility model, structural feature in detail, being realized purpose and effect, below for example and conjunction with figs. is detailed gives explanation.

See also Fig. 2, the utility model electric connector 1 comprises that an insulating body 10, some conducting terminals 20 and two that is installed on the insulating body 10 are installed in and helps weld tabs 30 on the insulating body 10.

See also Fig. 3 and Fig. 4, it is rectangular-shaped that insulating body 10 roughly is, and the left and right two ends of its upper surface offer an accepting groove 11 respectively downwards.The forward and backward two ends of the diapire of each accepting groove 11 all offer the draw-in groove 12 that extends about respectively.The center of the and arranged on left and right sides face of insulating body 10 inwardly offers a fluting 13 that is communicated with accepting groove 11 that run through up and down respectively.The lower surface center of insulating body 10 offers the embeded slot 14 that extends about, all offers some terminal grooves that run through up and down 15 on front and back two cell walls of this embeded slot 14.

See also Fig. 3 and Fig. 5, help weld tabs 30 to have the welded plate 31 of a long plate shape, one lateral margin center of welded plate 31 inwardly offers an auxiliary fluting 311 that runs through up and down, another lateral margin of welded plate 31 inwardly offers three overflow launders 312, overflow launder 312 in the middle of wherein the being positioned at shape that roughly is rectangle, two overflow launders 312 are the large semicircle shape in addition, and the front and back length of each overflow launder 312 is all less than the front and back length of assisting fluting 311.The rear and front end of welded plate 31 bending has downwards respectively protruded out a card body 321, and a lateral margin of card body 321 has protruded out a bayonet lock 322, and this bayonet lock 322 constitutes card division 32 with card body 321.

Please consult Fig. 3 and Fig. 6 in conjunction with Fig. 2, when assembling the utility model electric connector 1, plurality of conductive terminals 20 is installed in respectively in the terminal groove 15 of insulating body 10.Two help weld tabs 30 to be installed in the left side of insulating body 10 respectively, right two ends, help the welded plate 31 of weld tabs 30 to be contained in the accepting groove 11 and be covered on the fluting 13, thereby the overflow launder 312 of welded plate 31 is communicated with fluting 13, auxiliary fluting 311 is accommodated the cell wall of the accepting groove 11 of insulating body 10, wherein one help in the corresponding respectively a pair of draw-in groove 12 that is fastened in insulating body 10 left ends in a pair of card division 32 of weld tabs 30, another helps in the corresponding respectively a pair of draw-in groove 12 that is fastened in insulating body 10 right-hand members in a pair of card division 32 of weld tabs 30, and the bayonet lock 322 of card division 32 can increase the fixing intensity of card division 32 and draw-in groove 12, helps weld tabs 30 to be firmly fixed on the insulating body 10 thereby can make.

Please consult Fig. 2 and Fig. 6 again, when the utility model electric connector 1 being fixed on the circuit board (not shown), by the welded plate 31 direct and circuit board welding that help weld tabs 30, and because welded plate 31 is covered on the fluting 13, overflow launder 312 is communicated with fluting 13, so scolding tin can flow to the lower surface of welded plate 31 and then coat this welded plate 31 by overflow launder 312 when welding, can increase the weld strength of welded plate 31 and circuit board, thereby the utility model electric connector 1 is firmly fixed on the circuit board.
