Embodiment

For better understanding the utility model, it is described further below in conjunction with a preferred embodiment of the present utility model.

Be illustrated in figure 2 as the stereogram of present embodiment electric connector 1, this electric connector 1 is to be assembled in as in the portable electric appts such as mobile phone (not shown), to connect its battery 3 (see figure 8)s on circuit board 4 (see figure 8)s, comprise that one roughly is insulating body 10 and some conducting terminals 20 that is contained in this insulating body of L shape.

For convenience of description, present embodiment is depicted as horizontal direction with AA ' among Fig. 2, and with the place ahead that is oriented to of arrow A.Please in conjunction with referring to Fig. 3, present embodiment insulating body 10 comprises a front end face 11, the rear end face 12 relative with front end face, with front end face 11 adjacent end faces 13, and with end face 13 opposed bottom surface 14.Wherein, 12 run through bottom surface 14 and be formed with some accepting grooves 15 to back end from front end face 11, each accepting groove 15 both sides is provided with limited step 151 in the place, inboard of front end face 11, the front end face 11 that is concaved with 15 of holding slot 152, two accepting grooves in rear end face 12 extends to form several pieces preceding barricades 16 downwards.

In conjunction with Fig. 4,5 show, conducting terminal 20 comprises that respectively one is welded in the weld part 21 on the aforementioned circuit plate, connecting portion 22 from weld part 21 1 ends bending extension, this connecting portion 22 is provided with holding parts 221 with the both sides of weld part 21 connections, and the upwards also inflection formation forward of the other end of connecting portion 22 relative weld parts 21, connecting portion 22 bends forward and extends to form elastic arm 23, this elastic arm 23 further comprises second elastic arm 232 from first elastic arm 231 that connecting portion 22 extends forward and (promptly the direction to weld part forms a drift angle) bending extension under 231 continuation of first elastic arm also are partial to forward, these second elastic arm, 232 another terminal first contact sites 24 that form, first contact site 24 is the limiting section 26 of inflection formation conducting terminal 20 backward, and these limiting section 26 terminal both sides outwards convex with guide vane end stop 261.In addition, in second contact site 25 of the second elastic arm outside bending in 232 close first contact site, 24 places with convex outside forming, the position of these second contact site, 25 bendings and degree depend on after conducting terminal 20 first contact sites 24 electrically contact mutually and are pressed down with battery 3, this second contact site 25 can successfully realize and 3 unremitting electrical contacts of battery, and reach on the battery 3 electric contact region in vertical direction displacement the suitable purpose that reduces is arranged.

As Fig. 6, during assembling, conducting terminal 20 is in the direction of arrow A from the rear end face 12 of insulating body 10 forward in the corresponding terminal containing slot 15 that inserts insulating bodies 10 of end face 11, second elastic arm 23 and first, second contact site 24 of conducting

terminal

20,25 will expose to outside the front end face 11 of insulating body 10, the guide vane end stop 261 of its limiting section 26 ends is formed in the limited step 151, and the holding parts 221 of connecting portion 22 both sides is arranged in the holding slot 152 of corresponding position, accepting groove 15 both sides.

During work, electric connector 1 is mounted on the circuit board of portable electric appts such as mobile phone, as Fig. 7, shown in 8, its weld part 21 is welded on the circuit board 4, one battery 3 from the front end of electric connector 1 at first with the electrically contact and make it be subjected to a pressure mutually of first contact site 24 of each conducting terminal 20, along with further compressing into of battery 3, the distortion that the connecting portion 22 of conducting terminal 20 makes generation conducting terminal be biased to for 20 times to reach dotted line position among Fig. 7,8 together with elastic arm 23 (barricades 16 can prevent that conducting terminal from producing lateral shift before the insulating body 10).At this moment, the contact site of conducting terminal 20 and battery 3 is by i.e. first contact site 24 i.e. second contact site 25 of contact position that slides onto operating state of original initial contact position, and its displacement on battery contact area vertical direction is the H1 shown in the figure; And the contact point displacement in vertical direction of conducting terminal 20 and battery is not H2 when conducting terminal 20 second contact sites 25 are set.Thus, after present embodiment is set up second contact point 25, the contact position of itself and battery significantly reduces at the displacement of vertical direction, so, conducting terminal 20 can not be offset the loose contact that contact area caused of battery because of the significantly displacement of its contact site on battery 3, simultaneously, the reduction that the height of the electric contact region of battery 3 and conducting terminal 20 also is able to, so the design of present embodiment electric connector has not only improved the reliability that electrically connects between itself and battery, also reduced electric connector and battery shared space in electronic equipment simultaneously.

In addition, connecting portion 22 outsides of present embodiment conducting terminal 20 convex with strengthens fin 222 strengthening the strain intensity of conducting terminal 20, the protruding side in second contact site, 25 outsides have contact fin 251 when realizing that more reliably conducting terminal 20 in working order with being electrically connected of 3 on battery.
