Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.

As shown in fig. 1, according to the embodiment of the utility model provides a metal connecting piece of multiaspect contact, including bayonet joint 1, with contact pin 6 of 1 joint of bayonet joint, the top of bayonet joint 1 is provided with interface 7, all be provided with the recess on preceding, the left side of bayonet joint 1, the back, preceding, the left side, at the back be equipped with shell fragment one 8, shell fragment two 10, shell fragment three 13 on the top inner wall of recess in proper order, shell fragment one 8, shell fragment two 10, shell fragment three 13 all with contact pin 6 contacts, the bottom of bayonet joint 1 is connected with connecting plate 4.

As shown in fig. 1-2, in this embodiment, a first reinforcing rib 3 is disposed between the plug 1 and the welding plate 4, and a second reinforcing rib 5 is disposed at the bottom end of the connecting plate 4, so as to increase the structural strength of the metal connector.

As shown in fig. 1-2, in this embodiment, the first force arm 9 is disposed on each of two sides of the first elastic piece 8, and the second force arm 12 is disposed on each of two sides of the third elastic piece 13, so that the contact between the connector 1 and the pin 6 is firmer.

As shown in fig. 1-2, in this embodiment, the front and the back of the plug 1 are sequentially provided with a first limiting groove 11 and a second limiting groove 14, which can increase the stability of the overall connection structure of the metal connecting piece.
