[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 in which the connecting member is not inserted, 92578.doc -5- 1246232 is set by an alchemist who makes the second contact portion μ contact with the bottom wall of the holding hole of the housing, but it is set The height of the contact portions of the first sheet portion is highly dispersed, so that the so-called coplanarity of the plural contact portions cannot be achieved. The name shows that it is basically curved, etc. It is slightly hard. It is slightly used. On the other hand, the FPC as a connecting member is soft, but it is easy to insert when it is not folded (rigid) when inserted into the housing. , Workability is better. Therefore the situation of FPC. As mentioned above, in the case where the height of the contact part is dispersed or when a rigid FPC is used, there is a possibility that the contact part of the first ice contact may not be in good contact with the connection member. [Summary of the Invention] / For those who have more than one question on the hairpin, read the case where the south of the contact port P for contact is scattered or the case where the rigidity is used to obtain a small electrical connector. purpose. y In order to achieve the above-mentioned object, the present invention is characterized by having a plurality of contacts, which has a flat connection structure σ that can be inserted along a specific insertion direction and a narrow opening that can be elastically expanded. ; And an insulating shell having a plurality of trough holes that respectively receive at least a portion forming a narrow hole of each contact, the above-mentioned contact system includes: a main body portion; a fixed mark, which is parallel to the above-mentioned entrance from the main body portion to M- ^ Extending in the direction, pressed into the fixing hole of the shell; and an elastic beam, which extends from the main body into the receiving hole of the shell. The above elastic beam system includes: f f σ 卩, /, which extends parallel to the above-mentioned fixed beam ', and a second piece portion, which is folded back by Xi Sheng μ 4 /, and is returned by the apex portion of the first piece portion, and A narrow hole is separated between the i-th piece opening P, and a pressing part for pressurizing the connection member inserted into the narrow 92578.doc 1246232 hole in the ninth piece is provided at the tip of the 9th piece. , The connection member is not inserted ::: The opposite of the force of the rebound force to this ... The small one: the state of the younger brother, the younger brother can only move elastically in the small gap. That is, the height of the contact parts of ^ pieces ^ touches are scattered, or as a connection: In the case of sucking a relatively rigid FPC, the first member Γ1Γ can be used to reliably contact the connecting member with all the contact parts. . In addition, as long as the above-mentioned minute gap is 0.02 to 0.001 mm, it is preferable that the miniaturization of the two-phase electrical connection piping and the reliable connection to the contact portion can be achieved. Further, as long as the base end portion of the first piece portion serving as the bending fulcrum of the elastic flap is separated by the edge portion corresponding to the facing wall, the point where the ^ piece portion can be elastically moved only in a portion with a small gap is as follows: good. And 'There is no partition wall extending from the facing wall of the housing to the facing wall from the opposite side wall to partition the side of the receiving hole, and the partition wall has a connecting member to be inserted between the narrow holes. In the case where the leading end portion is pushed toward the inclined surface on the side of the i-th piece portion, 'By pushing the leading end portion of the inserted connection member toward the M-th portion', the biasing force of the connecting member to the contact portion of the first piece portion can be reliably assured. The contact pressure (contact pressure) on the contact portion is obtained. [Embodiment] A good embodiment of the present invention will be described with reference to the accompanying drawings.
