Each of the connecting portion 33, a fixing piece 34 horizontally bent leftward from the lower end of the contact portion 31, and a fixing piece 35 horizontally bent leftward from the rear end of the terminal portion 32. ing.

Therefore, the fitting member 16, the outer frame member 24
And the assembly with the male electrical contact 30 will be described.
First, as shown in FIG. 10, the contact portions 31 of the male electrical contact 30 are inserted into the vertical small holes 22 and the horizontal small holes 23 of the fitting member 16.
Then, the fixing piece 34 is inserted, and the contact portion 31 is exposed to the concave portion 19 of the fitting member 16 and fixed.

Next, as shown in FIG.
6, when the outer frame member 24 is inserted from the side of the support plate 20, the support plate 20 is inserted into the lateral groove 27 of the outer frame member 24, and the terminal of the male electrical contact 30 is inserted through the vertical narrow hole 28 of the outer frame member 24. The portion 32 protrudes outward in a horizontal state, and the fixing piece 35 is inserted into the lateral narrow hole 29 and fixed. The outer frame member 24
Is located on the upper surface of the regulating plate 21 of the fitting member 16.

As a result of assembling as described above, when the fitting member 16 and the outer frame member 24 are integrally connected via the U-shaped connecting portion 33 of the male electrical contact 30, the fitting member 16 and the outer frame member 24 are fitted together. The joining member 16 is movable in the horizontal direction with respect to the outer frame member 24. Further, since the arm portion 26 of the outer frame member 24 is located on the upper surface of the regulating plate 21 of the fitting member 16 and outside the tall side wall 18 of the fitting member 16, the horizontal direction of the fitting member 16 and Regulate the amount of vertical movement.

Numeral 36 denotes a female connector which can be fitted to the male connector 15 and a housing of the female connector 36 corresponds to the contact portion 31 of the male electrical contact 30 exposed in the concave portion 19 of the male connector 15. Position of the female electrical contact 37
Is stored. The female electrical contact 37 is of a tuning fork type, and is bifurcated toward the tip as shown in FIGS. 14 and 15, and the contact surface at the tip forms an electrical contact portion. Part 38 and the contact part 38
And a terminal portion 39 which is bent at right angles to the contact portion 38 from the middle thereof. The female connector 36 is set on the printed circuit board P2, and the terminal 39 is soldered to a printed circuit on the board.

Next, the case where the male connector 15 is mounted on the printed circuit board P1 will be described. First, as shown in FIG. 12, a rectangular shape slightly larger than the outer frame member 24 of the male connector 15 is formed on the printed circuit board P1. A square hole 40 is formed. Next, the male connector 15 is inserted into the square hole 40 from the surface of the printed circuit board P1 so as not to contact the square hole 40, and the terminal portion 32 of the male electrical contact 30 protruding from the side of the male connector 15 is inserted. Is brought into contact with the printed circuit foil on the surface and soldered.

Alternatively, as shown in FIG. 13, when the printed circuit foil is formed on the back side of the printed board P1, the square hole 4 of the printed board P1 formed as described above is used.
The male connector 15 is inserted from the back surface of the printed circuit board P1, and the terminal portion 32 of the male electrical contact 30 projecting from the side of the male connector 15 is soldered to the printed circuit foil on the back surface. Thus, the height of the mounting portion of the male connector 15 can be reduced by the thickness of the printed circuit board P1.

Next, as shown in FIGS. 14 and 15, the female connector 36 mounted on the printed board P2 is fitted into the concave portion 19 of the fitting member 16 of the male connector 15 mounted on the printed board P1. For example, the contact portion 31 of the male electrical contact 30 is inserted into the contact portion 38 of the female electrical contact 37 to be electrically connected. In this case as well, both printed circuit boards P1 and P2 on which the male connector 15 and the female connector 36 are mounted.
The spacing between them can be very small.

A load such as twisting is applied to the male connector 15 mounted on the printed circuit board P1 when fitting or removing the female connector 36 mounted on the printed circuit board P2. The member 16 and the outer frame member 24 are connected via the U-shaped connecting portion 33 of the male electrical contact 30. Since the fitting member 16 moves in the horizontal direction and upward and downward, the outer frame member 24 is The load is reduced, and the load applied to the terminal portion 32 of the male electrical contact 30 via the outer frame member 24 is the printed circuit board P1.
Of the terminal portion 32, and almost no load is applied to the soldered portion of the terminal portion 32.

[0022]

Since the present invention has the above-described structure, (1) a connector having a low height can be obtained, and the space between the two printed boards can be reduced. (2) Since the load applied when the mating connector is inserted or removed is distributed to the fitting member, the connecting portion of the electric contact, the outer frame member, and the printed circuit board, a load is not easily applied to the soldered portion of the terminal portion. (3) The height of the mounting portion can be reduced by the thickness of the printed circuit board, so that space saving and SMD (surface mounting component) can be easily achieved. (4) It can be mounted on both sides of the printed circuit board, and the degree of freedom of mounting is improved. There are various effects.
