[Prior technology] An electrical connector has a connection member such as FPC inserted from the front through the opening of the housing with a specific insertion force between the narrow holes in contact, and the contact portion (contact point) is obtained by the elastic rebound force of the narrow hole. Contact pressure), so-called Non-ZIF (Non-Zero Insert Force: non-zero insertion force) type. On the other hand, there is a ZIF (Zero Insert Force: Zero Insertion Force) that inserts the connection member into the housing without insertion force, and closes the cover to pressurize the connection member at the contact portion of each contact to ensure the contact pressure (contact pressure). Force) type of electrical connector. Among them, there are also so-called W-ZIF (Double Zero Insert Force) type electrical connectors where the contact portions of the first and second contacts pushed into the housing from the rear are mutually offset from each other (for example, JP 2002) -252049). In the electrical connector of JP-A-2002-252049 mentioned above, the second contact is pushed into the housing from the front, and the second contact portion is arranged rearward than the first contact portion of the ZIF type ( Insertion direction side of the connecting member) can make it Non-ZIF type. At the second contact pressed in from the front of the case, a first piece portion extending rearwardly along the bottom wall of the holding hole of the case from the main body portion disposed in front of the case is provided in a U-shape direction from the tip of the first piece portion. The second piece is folded back obliquely. In order to miniaturize the electrical connector, in a state where the connection member is not inserted, 92578.doc -5- 200428706 is set in such a way that the second contacting piece of the first contact with the bottom wall of the holding hole of the casing The height of the contact portions provided in the i-th sheet portion is highly dispersed, so that the so-called coplanarity of the plurality of contact portions cannot be achieved. On the other hand, Fpc, which is a connecting member, is known to be basically soft, but it does not bend when it is inserted into the housing. It has a relatively small degree of rigidity (rigidity) and is easier to insert, and has better workability. Therefore, there are cases where a slightly rigid FPC is used. As described above, in the case where the height of the contact portion is dispersed or when a rigid FPC is used, there is a possibility that the contact portion of the second contact and the connection member may not be in good contact. [Summary of the Invention] The present invention is a small electrical connector that can be reliably connected when the south of the contact part for contact is scattered or when a rigid FPC is used, etc. purpose. / In order to achieve the above-mentioned object, the present invention is characterized in that: a plurality of contacts are provided, which have narrow holes that can be elastically expanded in a manner capable of introducing a flat connection member inserted along a specific insertion direction; and insulation The outer shell is located in a horizontal row and has at least a narrow hole forming contact with the material. The contact system includes: a main body portion; a fixed beam, which extends from the body parallel to the specific insertion direction. The fixing holes in the casing are repeatedly inserted; and the elastic beam extends from the main body portion into the receiving holes of the casing. : Release: The raw beam system includes: the first section, which extends parallel to the fixed beam, and the second section, which is folded back from the tip of the i section, and the area between the first section A narrow hole is provided at the front end portion of the second piece portion, and an elastic rebound force i of the crotch portion of the contact portion of the first piece portion is inserted at 92578.doc -6- 200428706-like connection member i: plus C⑷, In the state where the connecting member is not inserted into the narrow hole, a small gap is provided between the first piece and the opposite pair. In the present invention, the first! The piece can be moved elastically only in the part of the small gap, even if the height of the contact portion of each contact is dispersed, or as a connecting member 'for example, when a relatively rigid coffee is used, the first and second pieces are used. : Absolutely contact the connecting member with all contact portions. In addition, the small clearances described above will hardly affect the height of the electrical connector, and will not be reduced in size. As long as the above-mentioned minute gap is 0.02 to 〇1, the miniaturization of the two-pole electrical connector and the point that the connection to the contact portion can be surely made are preferable. Further, as long as the base end portion of the first piece portion that becomes the bending fulcrum of the elastic beam is separated by the edge portion corresponding to the facing wall, the M portion can be reliably moved only elastically at a small gap portion. Better. In addition, a partition wall extending from the opposing wall of the housing to the opposing wall from the opposing wall to partition the side of the receiving hole is provided, and the partition has a leading end of a connecting member to be inserted between the narrow holes. In the case where the part is urged to the inclined surface of the first piece part side, the urging force of the connecting member to the contact part of the first piece part can be reliably obtained by pushing the leading end of the inserted connecting member toward the first piece part. Apply pressure to the contact (contact pressure). [Embodiment] A tea photo will illustrate a preferred embodiment of the present invention. Fig. 1 is a schematic plan view of a closed state of an electrical connector in an embodiment of the present invention, and Fig. 2 is a schematic front view of an electric connector in a closed state of a lid. Referring to Figs. 1 and 2, an electrical connector is provided with a housing, which is a fixed housing made of an insulating synthetic resin as an insertion space 3 for separating and inserting a connection member 2 (see Fig. 6) such as FPC from the front. The front half of the casing 4 can be opened upward as shown in FIG. 6 through the opening portion 6 of the upper plate portion ^ of the casing 4. Referring to FIG. 丨, a cover 7 is provided on the housing 4 as a movable housing that can rotate freely around the rotation axis c. The housing 7 is made of an insulating synthetic resin molded product, as shown in FIG. The opening 6 is turned on and off by turning. Referring to Fig. 1, the cover 7 is reinforced by, for example, reinforcing lines 8, 9 having a circular cross section as a reinforcing member. A part of the reinforcing wires 8 and 9 is inserted and buried when the resin of the cover 7 is formed. On the other hand, the reinforcing wire 8 is a pair of side portions 7 of the cover 7 and is respectively bent into a crank shape. One pair of ends of the reinforcing line 8 is formed by a pair of side portions of the cover 7 to form a rotation support shaft. 10. Each rotation support shaft 10 extends to both sides along the rotation axis c of the cover 7, respectively. Each of the rotation support shafts 10 is supported by a metal reinforcing plate 12 which is respectively fixed due to the side plates U corresponding to the casing 4. One pair of end portions of the reinforcing wire 9 on the other side are exposed by one side portion of the cover 7, and a pair of locking engaging portions 13 are formed by the exposed portions. Each locking engaging portion 13 is engaged with the reinforcing plate 12 to lock the cover 7 in a closed state. Both side portions of the above-mentioned insertion space 3 are separated by a side plate u facing the case 4. In addition, a plurality of first and second contacts 14, 15 are alternately arranged in the lateral direction in the case 4. ^ Mai Zhao, Figure 3 along section m_Iim in Figure 2. The reinforcing plate ⑽ includes a main body portion 16 and a fixing piece portion 18 which extends from the main body portion 16 to the casing 4 92578.doc -8-200428706 and is inserted into the fixing hole 17 from the front side to be fixed by a buckle projection; The extension piece 19 is extended upward from the main body portion 16; the second extension piece 20 is extended diagonally from the main body portion 16; and the third extension piece 21 is extended downward from the main body ㈣ Assume. The first extension piece 19 is provided with a rotation support portion 22 of a groove for rotatably supporting the rotation support shaft 10. The removal-restriction portion 23 of the housing 4 formed by a protrusion, for example, prevents the rotation support shaft 10 from being detached by the rotation support portion 22. The second extension piece 20 includes a locking portion 24 formed by an arc surface. When the cover 7 is closed, the locking portion 3 and the locking portion 24 are locked to lock the cover 7 in the closed state. The third extension piece 21 has a fixing portion 26 which is soldered to the surface 2 5 3 «of the circuit board 25. Next, referring to FIG. 4 of the cross-sectional view taken along the line IV-IV in FIG. 2, the first contact 14 is formed by sheet metal and is installed behind the casing 4. The first contact 14 includes: a main body portion 27; a fixing piece portion 29, which is fixed forward from the upper portion of the main body portion 27 to the fixing portion 28 extended to the housing 4 through a fastening projection; an elastic piece portion 30, which is made of the main body The lower part of the part 27 is extended in the insertion space 3 forward; and the lead part 31 is extended from the lower end of the main body part 27 to the rear face of the case 4 and is soldered to the surface 25 a of the circuit board 25. Referring again to Fig. 4, the elastic portion sheet 30 is received from the rear by a receiving groove 33 formed on the upper surface of the lower plate portion 32 of the case 4.
