っている。2. Description of the Related Art Conventionally, there is a card edge connector disclosed in Japanese Utility Model Publication No. 1-151683. This is the male housing 101, as shown in FIG.
By accommodating the edge portion of the circuit board 102 in, the terminal metal fitting 104 in the female housing 103, and fitting the female housing 103 into the male housing 101,
The terminal fitting 104 is connected to the circuit board 102.

ている。The terminal metal fitting 104 has an elastic contact piece 105 which makes elastic contact with the contact portion of the circuit board 102. The elastic contact piece 105 needs to be opposed to the flat circuit board 102, and therefore the terminal metal fitting 104 of the terminal metal fitting 104 is required. There is no choice but to be exposed on the outer surface. Therefore, as shown in FIG. 8, the terminal fitting 104 has a protection piece 1 for protecting the elastic contact piece 105 when it is removed from the female housing 103.
06 is provided. The protection piece 106 is the circuit board 10.
In order to avoid interference with 2, the circuit board 102 is provided so as to be located on the opposite side of the elastic contact piece 105.

を配列した場合と何ら変わらないのである。Generally, in the card edge connector, if the terminal fitting is in contact with only one surface of the circuit board, the lateral width of the female housing becomes large, and the lateral width is reduced. For the purpose, the terminal fittings are distributed and arranged on both surfaces of the circuit board. However, in the card edge connector of the above publication, even if the terminal fittings 104 are arranged so as to sandwich the circuit board 102, the width dimension cannot be reduced. This is due to the structure in which the terminal fitting 104 includes the protective piece 106 located on the opposite side of the elastic contact piece 105 with the circuit board 102 interposed therebetween. That is, the circuit board 1
On the upper surface of 02, since the elastic contact piece 105 of the upper terminal fitting 104 and the protective piece 106 of the lower terminal fitting 104 are arranged side by side, the elastic contact piece 105 and the protective piece 106 interfere with each other. In order to avoid this, as shown in FIG. 9, the upper terminal fitting 104 and the lower terminal fitting 104 are
There is no choice but to make a zigzag arrangement so that they do not overlap with each other in the vertical direction and, moreover, to secure a space in which one terminal fitting 104 can be placed between the two terminal fittings 104 sandwiching the protection piece 106. Therefore, the width of the female housing 103 is
The terminal metal fitting 104 is provided along only one surface of the circuit board 102.
It is no different from arraying.

Since the contact portion 25A of the elastic contact piece 25 of the terminal fitting 20 before being inserted into the 0 protrudes above the outer wall portion 24, foreign matter may interfere with the contact portion 25A from above. The terminal fitting 20 of the present embodiment has a contact portion 25A.
Since the protection portion 27 is provided above the above, it is possible to prevent foreign matter interference from above. Such terminal fitting 20
Is inserted into the housing 10. At this time, most of the terminal fitting 20 excluding the protective portion 27 is inserted into the cavity 11, and the protective portion 27 enters the escape groove 14. When the terminal fitting 20 is inserted to the regular position, the elastic contact piece 25 and the protection portion 27 reach the position corresponding to the board housing portion 13. From this state, the circuit board P is placed in the board housing portion 13.
When is inserted, the elastic contact piece 25 elastically bends and the contact portion 25A elastically contacts the circuit board P. At this time,

体の幅寸法を小さくすることができる。The plurality of terminal fittings 20 inserted in the housing 10 in this manner are divided into two upper and lower groups (stages) which are symmetrical with respect to the circuit board P, and the upper surface (lower surface) of the circuit board P. Adjacent to (in lower)
In order to avoid the interference between the outer wall portion 24 of the terminal metal fitting 20 and the protective portion 27 of the lower (upper) terminal metal fitting 20, they are arranged in a staggered manner. Here, the width dimension Wb of the protective portion 27 in the parallel direction of the terminal fittings 20 is set smaller than the maximum width dimension Wa of the terminal fittings 20. Therefore, compared with the conventional one in which the width of the protective portion is the same as the maximum width of the terminal fitting, the terminal fittings are arranged in a zigzag manner.
It is possible to narrow the pitch between the terminal fittings 20 located on both sides of 7. As a result, the width of the entire housing 10 can be reduced.

Since it is directed in the parallel direction of 0 (left-right direction), the protection unit 2
A wide vertical plate surface sandwiching the circuit board P in 7 is secured, and the vertical rigidity of the protective portion 27 is improved. As a result, both securing the strength of the protective portion 27 and narrowing the width are realized. In addition, the protection unit 27 is 2
Since the sheets are stacked, the strength is also increased in this respect. Moreover, since the two protective portions 27 are supported by the different outer wall portions 24, the external force acting on the both protective portions 27 is distributed to the two outer wall portions 24, and the stress concentration on the outer wall portions 24 is reduced. It has been avoided.

［実施形態２］次に、本発明を具体化した実施形態２を
図６を参照して説明する。When a downward external force (a direction approaching the contact portion 25A) along the plate surface acts on the protective portion 27, the inclined portion 26 causes the rising end 24A of the outer wall portion 24 to move.
It tries to fall inward with the fulcrum as a fulcrum.
Since the tilting direction is the direction in which the abutting force between the protective portions 27 increases, the tilting operation of the inclined portion 26 is restricted by this abutting action, and consequently the downward displacement of the protective portion 27 is prevented. [Second Embodiment] Next, a second embodiment of the present invention will be described with reference to FIG.

The configuration is different from. Since the other configurations are the same as those of the first embodiment, the same reference numerals are given to the same configurations, and the description of the structure, operation, and effect is omitted. In the terminal fitting 30 of this embodiment, the inclined portion 26 is not provided only on one outer wall portion 24. Then, from the protruding end (upper end) of the inclined portion 26, the protection portion 28 having the same shape and size as those of the first embodiment is formed when viewed from the side. The protection portion 28 is composed of a base portion 28A that is continuous with the upper end of the inclined portion, and a folded-back portion 28B that is folded back downward from the upper end of the base portion 28A and is in close contact with the base portion 28A. That is, when viewed from the front side, the protection unit 28 is the base unit 2.
It has a two-layer structure in which 8A and the folded portion 28B are stacked. Also in the terminal fitting 30 of the second embodiment, the maximum width dimension Wa of the terminal fitting 30 which is the distance between the outer surfaces of the outer wall portions thereof.
The width Wb of the protection portion 28 is set smaller than that of the above. Therefore, when the terminal fittings 30 are inserted into the housing 10 of the first embodiment in a staggered arrangement, the protection portion 2
The width between the terminal fittings 30 located on both sides of the protective portion 28 is narrowed by the small width dimension Wb of the housing 8.
The overall width dimension of 0 can be reduced.
