Thereby, the contact portion 92 and the pressing portion 93 of the terminal 90 are formed in a U-shape in a side view. The contact portion 92 has a contact 92 a protruding toward the pressing portion 93. The terminal 90 is inserted and fixed from the rear end side of the housing 81. In the terminal 90, the contact portion 92 and the pressing portion 93 are arranged in the fitting concave portion 83 of the housing 81.

  Next, a case where the flat circuit body 1 with a slide guide member in which the slide guide member 20 is assembled to the flat circuit body 10 is connected to the connector 80 will be described.

  The slide guide member 20 is brought close to the connector 80 in order to connect the flat circuit body 10 of the flat circuit body with slide guide member 1 to the connector 80. At this time, the flat circuit body 1 with the slide guide member is arranged with respect to the connector 80 such that the slide cover 60 side of the slide guide member 20 is on the circuit board 100 side.

  Then, the connection portion 12 of the terminal portion 11 of the flat circuit body 10 in the slide guide member 20 is fitted into the fitting concave portion 83 formed in the housing 81 of the connector 80 together with the housing insertion wall 33 of the slide body portion 30. . In this way, the connecting portion 12 of the terminal portion 11 of the flat circuit body 10 fitted into the fitting concave portion 83 enters between the contact portion 92 of the terminal 90 and the pressing portion 93, and each electrode of the connecting portion 12 A contact 92 a formed on the contact portion 92 of the terminal 90 comes into contact with 13 and is electrically connected.

  At this time, the housing outer guide wall 62 formed on the slide cover 60 of the slide guide member 20 enters the gap 84 between the circuit board 100 and the housing 81 without interfering with the housing 81 of the connector 80, and It is arranged along the side surface 81a.

  In addition, the guide projection 86 formed on the housing 81 of the connector 80 enters and engages with the guide groove 48 formed on the slide body 30 of the slide guide member 20. Further, the slide walls 41 formed on the slide body 30 of the slide guide member 20 enter and engage with the slide grooves 85 formed at both ends of the fitting concave portion 83 of the housing 81. As a result, the slide guide member 20 is inserted and guided into the housing 81 of the connector 80.

  Then, the lock projection 87 formed on the housing 81 of the connector 80 engages with the lock hole 38 of the connection lock portion 32 formed on the slide body 30 of the slide guide member 20. Thus, the slide guide member 20 assembled to the terminal portion 11 of the flat circuit body 10 is locked with respect to the housing 81 of the connector 80, and the connection state between the connector 80 and the terminal portion 11 of the flat circuit body 10 is maintained. You.

  As described above, according to the flat circuit body 1 with the slide guide member and the connection structure of the flat circuit body 10 and the connector 80 according to the present embodiment, the slide guide assembled to the terminal portion 11 of the flat circuit body 10 Since the insertion wall 33 in the housing of the member 20 supports only the surface of the terminal portion 11 opposite to the surface on which the electrode 13 is exposed along the insertion direction of the flat circuit body 10, the height of the slide guide member 20 is reduced. And a compact configuration. In addition, since the exposed electrode 13 of the terminal portion 11 is covered by the guide wall 62 outside the housing of the slide guide member 20, fingers are not applied to the electrode 13 of the terminal portion 11 at the time of connection work to the connector 80 or the like. There is no need to touch the ready. Therefore, even if the work space is particularly small, the connection work can be performed safely and satisfactorily with the mating connector 80.

  The outer guide wall 62 provided on the slide guide member 20 is guided along the outer surface 81 a of the housing 81 of the connector 80 when the connector 80 is connected to the connector 80. Thus, the terminal portion 11 of the flat circuit body 10 and the slide guide member 20 can be smoothly inserted into the housing 81 of the connector 80 without oblique insertion or gouging.

  Further, by sandwiching the terminal portion 11 between the slide body portion 30 and the slide cover 60, the slide guide member 20 can be assembled to the flat circuit body 10.
