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 without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides the following technical solutions: a double row pierce-type terminal connector comprising:

the terminal structure comprises a terminal end rubber shell 1, wherein an upper row and a lower row of terminals 2 are inserted in the terminal end rubber shell 1, each row of terminals 2 are distributed at equal intervals, and nine, seven or other numbers of terminals 2 are arranged in each row;

positioning element, positioning element includes blend stop 3, pull rod 4, external screw thread 5 and nut 6, blend stop 3 is made for insulating material, two rows of logical grooves 8 have been seted up on blend stop 3, every terminal 2 corresponds logical groove 8, the both ends of 1 one side of shell are glued towards the line end to pull rod 4 symmetry fixed in blend stop 3, the both sides of every terminal 2 all are fixed with dog 9, the both ends of 1 one side of shell are glued towards the blend stop 3 to the line end have been seted up and have been worn groove 10, pull rod 4 runs through and wears groove 10, external screw thread 5 sets up the outer wall of locating pull rod 4, nut 6 fits the one end that blend stop 3 was kept away from to pull rod 4 soon.
