[0024] Please refer to Figures 1 to 6 As shown in the figure, the pin connector 100 according to the present application comprises a longitudinal insulating body 10 and a plurality of conductive terminals 20 held on the insulating body 10. The conductive terminals 20 are assembled on the insulating body 10 from top to bottom in the vertical direction.

[0025] In combination Figures 4 to 5 As shown in the figure, the insulating body 10 is provided with a base portion 11 extending in the longitudinal direction and a rib portion 12 protruding upward from the top surface of the base portion 11. The base portion 11 is provided with a plurality of terminal grooves 111 penetrating the base portion 11 in the vertical direction and escape grooves 112 recessed downward from the top surface of the base portion 11. The escape grooves 112 are located on the longitudinal sides of the terminal grooves 111 and are communicated with the terminal grooves 111. Specifically, the terminal grooves 111 are arranged in two rows in the longitudinal direction, and two escape grooves 112 penetrating the base portion 11 are arranged on the longitudinal sides of each terminal groove 111.

[0026] The rib portion 12 is used to space apart two adjacent terminal grooves 111. Specifically, the rib portion 12 is provided with a long rib 121 extending in the longitudinal direction and a plurality of short ribs 122 extending outward in the transverse direction from the transverse sides of the long rib 121. The long rib 121 is used to space apart the two rows of terminal grooves 111, and the short ribs 122 are used to space apart two adjacent terminal grooves 111 in the longitudinal direction. Meanwhile, the long rib 121 and the short ribs 122 jointly form a containing groove, and the terminal grooves 111 are communicated with the containing groove.

[0027] In combination Figure 2 and Figure 6As shown, the conductive terminal 20 is provided with a holding portion 21, a contact portion 22 extending downwardly along the vertical direction from the holding portion 21, and a welding portion 23 extending outwardly along the horizontal direction from the top of the holding portion 21. The thickness of the holding portion 21 along the horizontal direction is greater than the thickness of the contact portion 22 along the horizontal direction. When the conductive terminal 20 is assembled to the insulating body 10, the contact portion 22 of the conductive terminal 20 can pass through the terminal groove 111 and the holding portion 21 is accommodated in the terminal groove 111. When the holding portion 21 is completely held in the terminal groove 111, the welding portion 23 is at least partially accommodated in the accommodating groove, thereby avoiding short circuit between the welding portions 23 of two adjacent conductive terminals 20.

[0028] Meanwhile, the provision of the material escape groove 112 reduces the extrusion force between the longitudinal side surface of the contact portion 22 and the holding portion 21 of the conductive terminal 20 and the inner wall of the terminal groove 111 when the conductive terminal 20 is inserted into the insulating body 10, thereby preventing the extrusion of the side surface metal wire of the conductive terminal 20, improving the efficiency and reducing the rework. Furthermore, the insulating body 10 is further provided with a positioning column 13 protruding upwardly from the top surface of the long rib 121, which is used to fix the pin connector 100 to a circuit board.
