Figure 7 shows a first embodiment of the corner connector of the invention: the middle of the first plug-in arm 21 is arched upwards, a first contact surface 212 capable of abutting against the inner wall of the first jack is formed at the arched top of the first plug-in arm 21, a first protrusion 211 protruding downwards is respectively arranged on two sides of the head of the first plug-in arm 21, and the protruding direction of the first protrusion 211 is opposite to the inserting direction of the first plug-in arm 21, so that the resistance of the first plug-in arm 21 to be pulled out from the first jack can be increased; when the first inserting arm 21 is inserted into the first inserting hole of the first frame profile 11, the root 213 and the first protrusion 211 of the first inserting arm 21 respectively abut against one side inner wall of the first inserting hole, and the first contact surface 212 of the first inserting arm 21 abuts against the other side inner wall of the first inserting hole; the middle of the second plugging arm 22 is arched upwards, a second contact surface 222 which can be abutted against the inner wall of the second jack is formed at the arched top of the second plugging arm 22, two sides of the head of the second plugging arm 22 are respectively provided with a second protrusion 221 which is raised downwards, and the raising direction of the second protrusion 221 is opposite to the inserting direction of the second plugging arm 22, so that the resistance of the second plugging arm 22 to be pulled out from the second jack 1210 can be increased; when the second inserting arm 22 is inserted into the second inserting hole 1210 of the second frame profile 12, the root 223 and the second protrusion 221 of the second inserting arm 22 respectively abut against one side inner wall of the second inserting hole 1210, and the second contact surface 222 of the second inserting arm 22 abuts against the other side inner wall of the second inserting hole 1210. Like this, the grafting arm is through the arch deformation of punching press formation and the bulge of perk protruding downwards respectively with jack inner wall bloated tight fastening be connected, the bulge that the punching press formed has elasticity and pawl effect for the grafting arm is easily inserted and is difficult for throwing off fully having guaranteed firm in connection. In order to further ensure the reliable connection, the convex part is preferably in surface contact with the inner wall of the jack; for convenience, the bulge, the arch top contact surface and the expansion force formed by the root part, the bulge, the arch top contact surface and the inner wall of the jack are far larger than the expansion force formed by the bulge, the arch top contact surface and the inner wall of the jack.
Fig. 8 shows a second embodiment of the corner connector of the present invention: the upper surface of the first plug arm 21 is provided with four first protruding parts 211 protruding upwards, which are not on the same straight line, and the protruding direction of the first protruding parts 211 is opposite to the inserting direction of the first plug arm 21, so that the resistance of the first plug arm 21 to be pulled out from the first jack can be increased; when the first inserting arm 21 is inserted into the first inserting hole of the first frame profile 11, the lower surface of the first inserting arm 21 abuts against the inner wall of one side of the first inserting hole, and the first protrusion 211 of the first inserting arm 21 abuts against the inner wall of the other side of the first inserting hole; the upper surface of the second plugging arm 22 is provided with four second protruding parts 221 which protrude upwards and are not in the same straight line, and the protruding direction of the second protruding parts 221 is opposite to the inserting direction of the second plugging arm 22, so that the resistance of the second plugging arm 22 to be pulled out from the second inserting hole 1210 can be increased; when the second inserting arm 22 is inserted into the second inserting hole 1210 of the second frame profile 12, the lower surface of the second inserting arm 22 abuts against one side inner wall of the second inserting hole 1210, and the second protrusion 221 of the second inserting arm 22 abuts against the other side inner wall of the second inserting hole 1210. Like this, the grafting arm is connected with the bloated tight straining of jack inner wall respectively through the protruding bulge of a plurality of downward perk that the punching press formed, and the bulge that the punching press formed has elasticity and pawl effect for the grafting arm is easily inserted and is difficult for throwing off fully having guaranteed firm in connection. In order to further ensure the reliable connection, the convex part is preferably in surface contact with the inner wall of the jack; in order to facilitate early-stage insertion adjustment and later-stage fixation, the height of the protruding part close to the root part of the insertion arm in the plurality of protruding parts is higher.
Fig. 9 shows a third embodiment of the corner connector of the present invention: the middle of the first insertion arm 21 is arched upwards, and the arched top of the first insertion arm 21 forms a first contact surface 212 which can be abutted against the inner wall of the first insertion hole; when the first inserting arm 21 is inserted into the first inserting hole of the first frame profile 11, the root 213 and the head 214 of the first inserting arm 21 respectively abut against the inner wall of one side of the first inserting hole, and the first contact surface 212 of the first inserting arm 21 abuts against the inner wall of the other side of the first inserting hole; the middle of the second insertion arm 22 is arched upwards, and the arched top of the second insertion arm 22 forms a second contact surface 222 capable of abutting against the inner wall of the second insertion hole; when the second inserting arm 22 is inserted into the second inserting hole 1210 of the second frame profile 12, the root 223 and the head 224 of the second inserting arm 22 respectively abut against one side inner wall of the second inserting hole 1210, and the second contact surface 222 of the second inserting arm 22 abuts against the other side inner wall of the second inserting hole 1210. Therefore, the inserting arm is in expansion connection with the inner wall of the inserting hole through the arch deformation formed by stamping, and is easy to insert and not easy to separate, so that the firm connection is fully ensured. In order to facilitate early-stage insertion adjustment and later-stage fixation, the expansion force formed by the head part, the arched top contact surface and the root part of the insertion arm and the inner wall of the insertion hole is far greater than the expansion force formed by the head part, the arched top contact surface and the inner wall of the insertion hole.
