FIG. 1 shows the male and female connectors 21 and 1 in a non-connected state, and FIG. 2 shows a mated and connected state. 3 to 7 show the female connector 1, and FIGS. 8 to 15 show the male connector 21 and the male terminal 24 used therefor. Therefore, the female connector 1 will be described first. This has a housing 2, and the housing 2 is formed with a terminal mounting portion 3 which communicates with the outside through an opening 12 on the top surface. A female terminal 4 is attached to the terminal mounting portion 3, and the female terminal 4 has a horizontal portion 17 that extends horizontally toward the upper side with the bent portion 5 that is bent in a U shape in the middle. And a rising part 18 that rises a little steeply beyond that, a contact part 6 provided at the end of the rising part 18 with a gentle slope, and a seat bent inside the tip of the contact part 6. On the other hand, it has a base part 7 attached to the floor part 16 of the housing 2 and a solder tail part 9 which is bent at a right angle at the tip of the base part 7. There is. What is important here is that the female terminal 4 is elastically deformed in the terminal mounting portion 3 by coming into contact with the contact portion 26 of the male terminal 24 of the male connector 21, which will be described later. That is, all of the female terminals 4 are located inside the terminal mounting portion 3 of the housing 2 even in the state in which is not added. That is, the contact portion 6 is not exposed to the outside of the top surface 10 of the housing 2. The top surface 10 of the housing 2 is covered with a metal cover 11 except for the opening 12 through which the male terminal 24 passes. The metal cover 11 is fixed to the top surface 10. In addition, the front and rear surfaces of the housing 2 are fixedly covered with the front and rear portions 13 of the metal cover 11, and the left and right side surfaces 14 of the metal cover 11 are fixedly fixed on the left and right side surfaces of the housing 2. It is covered. A horizontally extending earth bar 15 is integrally connected to the left and right side surfaces 14.

Next, the male connector 21 side will be described with reference to FIG. A flat floor 29 is formed on the housing 22 of the male connector 21, and a terminal mounting portion 23 is formed on the floor 29 so as to project therefrom.
