The following description of the embodiments of the present invention is provided to facilitate the understanding of the present invention by those skilled in the art, but it should be understood that the present invention is not limited to the scope of the embodiments, and various changes may be made apparent to those skilled in the art within the spirit and scope of the present invention as defined and defined by the appended claims.

As shown in fig. 1 to 5, the double-layer terminal connector of the present scheme includes an outer housing 2, a plug end 1 is provided on the outer housing 2, a first layer terminal 5 and a second layer terminal 7 are provided on the outer housing 2, the first layer terminal 5 and the second layer terminal 7 both include a plurality of side-by-side "Z" shaped terminals, the first layer terminal 5 and the second layer terminal 7 are stacked on each other, and the terminals between the first layer terminal 5 and the second layer terminal 7 are arranged in a staggered manner; the tail part of each terminal is provided with an L-shaped welding leg 6; first layer terminal 5 and second layer terminal 7 are all inlayed in shell body 2 through moulding plastics, and the head of terminal stretches into in grafting end 1.

This scheme carries out the electricity transmission or signal transmission through two rows of terminals, has strengthened signal transmission and current transmission function, does not increase the size of connector simultaneously, and crisscross the arranging between first layer terminal 5 and the second floor terminal 7 to increase gap and creepage distance. The first layer of terminals 5 and the second layer of terminals 7 are stable in structure in the outer shell 2, and cannot be damaged due to the change of self stress, so that the service life is prolonged.

Two locating holes 8 are formed in each terminal, the locating holes 8 are used for fixing the terminals, and the terminals are prevented from being inclined by molten plastic during injection molding. The head of each terminal is provided with a sinking platform 4, which plays a role of the terminal and prevents the head of the terminal from upwarping.

The welding leg 6 on the first layer terminal 5 and the welding leg 6 on the second layer terminal 7 are staggered, and the welding leg 6 of the first layer terminal 5 is as high as the welding leg 6 of the second layer terminal 7, so that the welding is convenient on a circuit board.

The tail of first layer terminal 5 is fixed on first material area 14, and the tail of second layer terminal 7 is fixed on second material area 13, all is provided with crease 10 between the tail of first layer terminal 5 and first material area 14, between the tail of second layer terminal 7 and second material area 13.
