New description: [New technical field] This creation is related to the connector structure of electronic products, especially a card edge connector for fixing flat or ribbon electronic cards. [Prior Art] With the development of electronic technology, various flat or ribbon electronic cards have been widely used in various electronic devices (such as electronic communication devices, computers, etc.), and electronic cards can be connected through card edge connectors. The connection terminal on n is electrically connected to the circuit board through the soldering leg, and the connector needs to fix the electronic card at the same time. At present, the existing connector mainly comprises: an elongated insulating body seat having a plurality of jacks, a set of parallel connecting terminals, and two cantilever supports for fixing the connectors at both ends of the insulating body seat The upper end of each connecting terminal has a contact portion which can be placed in the socket of the pure edge body seat, and the welding end provided at the lower end thereof is electrically connected to the circuit board outside the insulating charm to form a connection group plug electrode. . The (four) arm support frame is a metal member, which comprises a substrate, the end is fixedly connected to both ends of the insulating body seat, and the other end is a free end, and a bottom plate extends downwardly from the bottom plate to be fixedly connected to the circuit board. In the manufacture and assembly of connectors, the connection terminals and the cantilever support are usually soldered to the circuit board by surface soldering. ^ When connecting, all the solder joints on the connector must be on the same plane to ensure the quality of the soldering. In fact, because the insulating body seat is a long-shaped member, it is easy to produce a torsional deformation during the transportation of the parts and the assembly process with other parts. It is difficult to ensure that the two bottom plates are in the plane after the two cantilever support frames are connected. On the same design plane as required, the welding surface of the support frame bottom plate is inaccurate with other welding grades, resulting in poor joint welding. Also 5 M350119

The purpose of creation. The heart is called as shown in FIG. 5 and FIG. 6 'In the specific implementation structure, the hinge shaft on the cantilever support frame 2 is the two cantilever support frame 2 complementing the outwardly extending shaft 22, and the rotating shaft 22 can be The upper and lower ends each have a long strip-shaped member with a curved surface, the end is fixed to the cantilever support frame 2, and the other end is an opening; correspondingly, the auxiliary support frame 4 is adapted to the rotating shaft 22 The elongated l-shaped member includes a bottom edge 41 solderable to the circuit board 5, wherein the outward end of the bottom edge 41 includes an upwardly inverted edge 49 to increase the amount of solder deposited at the bottom end of the bottom edge 41 during soldering ( The solder can be stacked at the inverted edge 49 to increase the welding strength. Further, the other end of the bottom edge 41 extends upwardly with the upright portion 42' and the upper end of the upright portion 42 has a connecting portion 44 connected thereto, and the connecting portion is semicircular. The other end extends downwardly - the flange 47, and the flange 47 is parallel to the upright portion 42.

On the rotating shaft 22: thereby driving the leakage support frame 4 to move around, so that the lion support 4 and the cantilever support frame 2 are hingedly connected to each other. In the present embodiment, the reason why the rotating shaft 22 adopts a long strip structure can be matched with the structure of the cantilever support frame 2, and on the other hand, the stability of the auxiliary support frame 4 in the longitudinal direction can be maintained. As shown in FIG. 6, the upper and lower ends of the rotating shaft 22 are respectively in contact with the upper surface of the connecting portion 44 of the auxiliary supporting frame 4 and the upper surface of the bottom edge 41, wherein the mating surface of the connecting portion 44 and the upper end of the rotating shaft 22 is also an arc. The face, and the radius of the arc of the connecting portion 44 should be larger than the radius of the upper end surface of the rotating shaft 22. In this way, M350119 contact points are in contact, and the arc-face matching structure allows the connecting portion 44 and the rotating shaft 22 to always have a free rotation of the auxiliary supporting frame 4. 6, the observation of the branch of the 4th crane and the heat around the scales of the movement, as shown in Figure θ not 'this creation, the bottom of the lion support frame 4 Μ upward duct 46, the limit element elastic tongue The piece 46 is obliquely convex at the bottom edge of the auxiliary support frame 4, and the convex top end plane is in contact with the arc surface of the lower end of the rotating shaft 22, and can be restrained by the limiting element when the auxiliary supporting frame 4 is rotated to a certain angle.
