[embodiment]
See also Figure 1 and Figure 2, prior art electric connector 100 includes metal shell 10, is fastened in the osculating element 20 on this metal shell, and metal shell and osculating element formation one have the receiving space 101 of opening, with the camera models (not shown) of accommodating and osculating element 20 electrically contacts.
Described osculating element 20 generally comprises the insulator 21 that is the lengthwise shape and is immobilizated in several interior conducting terminals 22 of insulator, and described metal shell is covered in the insulator and the conducting terminal outside.See also shown in Figure 3, conducting terminal 22 is along the longitudinally setting that is staggered, and the two ends of each conducting terminal 22 have elastic contact arm 221, welding foot 222 and oblique extension of extending insulator and the connecting portion 223 that connects elastic contact arm and welding foot respectively; Wherein, has an elastic contact arm 221 between per two adjacent welding foots 222, and it is to be positioned at same horizontal plane that this elastic contact arm, welding foot stretch out part from insulating base, and promptly this elastic contact arm and welding foot take the length of insulator jointly on longitudinally.
See also Fig. 4 and shown in Figure 5, electric connector of the present invention improves at osculating element and innovates, and with prior art more different part is arranged:
Osculating element 30 includes along the insulator 31 of directions X (promptly referring to first direction, longitudinally) extension and is shaped in several interior conducting terminals 32 of insulator; Conducting terminal 32 extends to form along the Y direction (promptly referring to second direction) perpendicular to directions X, and the two ends of each conducting terminal have the holding parts 323 that the elastic contact arm 321 that extends insulator, the welding foot 322 relative with elastic contact part reach between elastic contact arm and welding foot.Conducting terminal 32 is divided into two and comes staggered relatively being inserted in the insulator on the directions X, the elastic contact arm 321 that is each conducting terminal is adjacent with the welding foot 322 of adjacent conductive terminal, or two extend in the same way and adjacent elastic contact arm between be provided with the welding foot of another conducting terminal.
The holding parts 323 of conducting terminal 32 is provided with kink 324, be connected to elastic contact arm, between welding foot and this kink first, second connecting portion 325,326, this kink 324 can make first connecting portion 325 and adjacent welding foot 322 be positioned on the Different Plane, first connecting portion that connects elastic contact arm is raise with respect to welding foot, promptly first, between second connecting portion perpendicular to X, the Z direction of Y direction (promptly referring to third direction) goes up and produces a height difference H, and the distance between elastic contact arm and the welding foot is more greater than the distance between first connecting portion and the welding foot, thereby this elastic contact arm and welding foot take the length on the insulator directions X no longer jointly, the width of elastic contact arm is increased relatively, increasing the elastic force of elastic contact arm, and then improve the contact performance of conducting terminal.
