The bet tn contact (10) has a sturdy solid <110 between the substrate 14 〇 5 solid = upper) and the embossed extension ' enables the movable side outer casing 120 to move relative to each other' and can extremely reduce the size of the up and down direction. A so-called low-profile floating connector having a small size in the down direction is known as a compact and lightweight connector having such a configuration. However, the above-mentioned conventional low-profile floating connector is located outside the 135 of the contact member 130 to protect it from impurities. The contact protection wall of the contact member is constituted by the fixed side 110, and the movable side casing (10) is hidden from the fixed side. When the phase of the outer casing 11G is deflected to the outside in the lateral direction (the left side of the eighth drawing surface), the flexible portion 135 is in contact with the fixed side casing 11 (refer to the circle in the dotted line in Fig. 8). Therefore, the movement of the living side casing 120 is limited to the range in which the flexible portion 35 contacts the fixed side casing u ’. The positional slip allowed when the object connection is reduced is limited to a minimum range. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems. It is an object of the present invention to provide a floating type connector in which the positional slip between the outer casings is allowed to be larger than that of the prior art when the target connector is fitted. The floating connector according to the present invention (for example, the socket connector 1 in the embodiment) has a fixed side outer casing fixed to the substrate and having an inner space, and is located in the inner space of the solid side outer casing, and the object connector (For example, the plug connector 70 in the embodiment), the fitting portion (for example, the accommodating recess 23 in the embodiment) is provided on the movable side outer casing on the opposite side of the substrate, and is held on the fixed side outer casing and the movable side outer & When a contact with the target connector is engaged with the target connector (for example, the contact 73 of the plug connector 70 in the embodiment), the contact portion is exposed on the surface of the fitting portion, and the plurality of contacts are provided. The U-shaped flexible portion formed between the first held portion held by the fixed-side outer casing and the second held portion held by the movable-side outer casing is elastically deformed. The movable-side outer casing is freely movable to the fixed-side outer casing. The flexible portion of each contact member protrudes from the movable side outer casing and the fixed side outer casing toward the opposite side of the substrate, and is formed in the contact protection wall of the movable side outer casing. 1,335,692 contacts within the protected space.

Further, the lead portion 33 extending from the first held portion 31 is connected to the wiring pattern 41 on the substrate 4 by soldering or the like, and the contact portion 34 extending from the second held portion 32 is exposed to the movable side case. The surface of the above-mentioned accommodating recess 23 is provided. Each of the contacts is formed with a U-shaped flexible portion 35 between the first held portion 31 and the second held portion 32. The flexible portion 35 extends between the concave wall 22 of the movable side casing 2 and the inner wall 11 of the fixed side casing 1 toward the opposite side of the substrate 4 (above the paper surface in FIG. 4), and the outer casing 10, 20 The left and right direction (the left and right sides of the paper in Fig. 4) is elastically deformed. ^ As shown in Fig. 4, the contact member protective wall 25 is extended from the left and right end portions of the movable side casing 2 to the side of the substrate 4 (the lower side of the paper surface in Fig. 4). Between the contact protection wall 25 / and the concave wall 22 , a contact portion of the contact member 3 of the substrate 2 is formed on the side of the substrate 4 (below the paper surface). The flexible portion 35 of each contact member 3 is located in the contact protection space 26 . In the above, the contact protection wall 25 protects the flexible portion 35 of the contact member 30 from the outside. It is set up with impurities such as sputum. As shown in Figs. 1 and 2, 50 is attached to the front and rear end portions of the fixed side casing 1A. The fixing fittings 50 have outer casing joint portions 51 and 51 at both end portions thereof, and the base portion of the fixed side casing 1 of the outer casing joints 51 and 51.

The plurality of contacts of the elastic conductive material connected to the plug housing 71 correspond to the contact members 30 along the front and rear sides 3, and are disposed at the left and right sides of the protrusions 72 at an arm-like distance. Each of the contact members 73 is freely deformed in the direction of the in-plane of the paper in FIG. 6 under the sixth drawing surface, and is connected to the substrate on which the object connector 70 is mounted (not shown). The protrusion 72 of the upper connection f70 is inserted into the socket connection from the top of the sixth drawing surface. The portion of the plug connector 70 is inserted into the valley recess 23 of the plug 395. The piece 73 is inserted into the contact piece 3G, and is elastically deformed in the plane of the sixth drawing, and the two suitable contact forces are in contact with each other. The two connectors 1 and 71 can be transmitted. As shown in Fig. 6, the socket connector 1 The central axis surface of the accommodating recess ^ is centered on the central axis surface S2 of the protrusion 72 of the sixth vertical plane (the central axis surface S2 also extends in the "direction" direction) - two In the combined operation of the connector block 71, the dog connector portion 72 of the plug connector and the housing recess portion 23 of the socket connector 1 are straight. si ^ S2 #) H, , ® concave β 23 is not directly fitted 'formed in the plug connector The raised portion 72a abuts against the upper portion 23a formed in the socket connector accommodating recess 23 from above. However, the movable side housing 20 is elastic. The body is made of the contact member 3, and the casing 10 is freely movable. Because of the abutment of the two inclined surfaces 72a, 23a, the lateral movement force of the outer casing 20 causes the movable side casing 2 to move in the direction (horizontal, !, and two inlays). The hinges 72, 23 are combined. Figure 7 shows the central axis surface S1 of the socket connection 3|, 23 and the recess of the protrusion 72 of the plug connector 70, and the movable side housing 20 is left to the sixth drawing surface. The movement of the square is separated. = - the flexible portion 35 of the contact member 30 located on the left side of the paper is deformed and the U-shaped portion 8 1335692 is narrowed and narrowed. The flexible portion 35 of the contact member 30 located on the right side of the paper is deformed and shaped. The state in which the interval under the adjacent portion is widened. ° Thus, the socket connector 1 according to the present embodiment can be absorbed when the position is slipped between the outer casing and the object connector (plug-in connector 70), and the outer casing can be absorbed. 20, 71 is not damaged and the two contact members 30, 73 are not plastically deformed, and the U-shaped flexible portion 35 of the contact member 30 can be surely directed between the movable side outer casing 2 and the fixed side outer casing 2 toward the substrate. 40 opposite sides of the convex extension, forming a so-called low-profile floating
