That is, the first bending portion 3131 protrudes from the surface of the first chamfered portion 141, the exposed surface of the slope guide portion 3132 is flush with the surface of the slope portion 142, and the second bending portion 3133 protrudes from the surface of the second chamfered portion 143.

When the male end connector and the female end connector are inserted in a non-aligned mode, the male end connector can collide with the first bent portion 3131 and cannot collide with the first chamfered portion 141, the male end connector can be inserted more smoothly under the guide of the inclined surface guide portion 3132, the second chamfered portion 143 cannot be collided with the female end connector in a follow-up mode under the guide of the second bent portion 3133, in the whole inserting process, the male end connector cannot be scratched in the whole process of inserting, the end face of the middle island 14 is favorable for prolonging the service life of the connector, meanwhile, the middle island 14 can be prevented from being scratched to generate fragments, the conduction performance of the connector is influenced, and the working stability of the connector is guaranteed.

As shown in fig. 4, in order to further ensure that the male terminal connector does not scratch the middle island 14, a third chamfer 144 is further provided at a connection angle between the side surface and the end surface of the middle island 14; a fourth chamfer 145 is further disposed at a connecting corner between the side surface and the top surface of the middle island 14, the fourth chamfer 145 is located at the end of the middle island 14, the top protection arm 312 is connected with the side protection arm 311 through a fourth bend 314, and the fourth bend 314 protrudes from the surface of the fourth chamfer 145.

Referring to fig. 9 and 10, in particular, the supporting portion 32 includes a bottom arm 321 and two receiving arms 322, the bottom arm 321 is connected to the third bending portion 3135, one end of each of the two receiving arms 322 is connected to the bottom arm 321, and the other end of each of the two receiving arms 322 extends toward the direction close to the end wall 12. Set up two and connect material arm 322 and can make things convenient for the automation in the female end connector forming process to draw material work, do benefit to and improve production efficiency, simultaneously, can also avoid end protection portion 25 on first gold utensil 2, that is to say, so set up, can avoid the leg of first gold utensil 2, realized the multiple use.
