っている。2. Description of the Related Art A conventional card edge connector is disclosed in Japanese Utility Model Laid-Open No. 1-161583. This is, as shown in FIG.
By accommodating the edge of the circuit board 102 in the female housing 103, the terminal fitting 104 is accommodated in the female housing 103, and the female housing 103 is fitted into the male housing 101.
The terminal fitting 104 is connected to the circuit board 102.

を配列した場合と何ら変わらないのである。By the way, generally, in a card edge connector, if the terminal fitting is brought into contact with only one surface of the circuit board, the width of the female housing becomes large, so that the width is reduced. For the purpose, the terminal fitting is distributed and arranged on both surfaces of the circuit board. However, in the card edge connector disclosed in the above publication, even if the terminal fittings 104 are arranged so as to sandwich the circuit board 102, the width cannot be reduced. This is due to the structure in which the terminal fitting 104 includes the protection piece 106 located on the opposite side of the elastic contact piece 105 across the circuit board 102. That is, the circuit board 1
02, the elastic contact pieces 105 of the upper terminal fittings 104 and the protective pieces 106 of the lower terminal fittings 104 are arranged side by side. In order to avoid this, as shown in FIG. 9, the upper terminal fitting 104 and the lower terminal fitting 104 are used.
Are arranged in a staggered manner so that they do not overlap with each other, and a space in which one terminal fitting 104 can be arranged must be secured between the two terminal fittings 104 sandwiching the protection piece 106. Therefore, the width of the female housing 103 is
The terminal fittings 104 are provided only along one surface of the circuit board 102.
Is no different from the case of arraying.

きる。Operation and effect of the present invention [Invention of claim 1] Between one set of terminal fittings adjacent in the same posture on one surface of a circuit board, interference with the other set of terminal fittings is avoided. Therefore, it is necessary to leave a space at least for the width dimension of the protection portion. In the present invention, since the width dimension of the protection part is set smaller than the maximum width dimension of the terminal fitting, compared to the case where the width dimension of the protection part is substantially the same as the maximum width dimension of the terminal fitting, the terminal fittings are arranged side by side. The spacing can be reduced, and the overall width of the housing can be reduced.

The width of the protection part can be reduced. [Invention of claim 3] Since the protective portion is formed by two sheets, further strength can be increased. In addition, since each protection portion is supported by a separate outer wall portion, the external force acting on the protection portion is distributed to the two outer wall portions, so that stress concentration on the outer wall portions can be avoided.
