Abstract

<P>PROBLEM TO BE SOLVED: To provide a connector capable of reducing a dimension from one end side of a rotating member to the other end side. <P>SOLUTION: A bearing portion 22a which supports rotation of a pressing cover 40 at one end side of the pressing cover 40 is provided so as to extend along a pressing direction of a first pressing member 43. Thus, when the pressing cover 40 rotates to a full open position, the bearing portion 22a does not intervenes between the one end side (rotation axis 12a) of the pressing cover 40 and the other end side (the first pressing member 43). Therefore, since the dimension from the one end side of the pressing cover 40 to the other end side can be reduced without considering a dimension of the bearing 22a, the connector can be miniaturized and then, meets demands of miniaturizing apparatuses. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a connector that is attached to a printed board or the like and is used to electrically connect a plurality of boards.

  Conventionally, as this type of connector, a connector main body in which one end of an object to be connected can be inserted into a predetermined position, a plurality of terminals arranged in the connector body at intervals in the width direction, and a connector main body. When the connection object is inserted into the connector body and the rotation member is closed, the contact portion provided on each terminal comes into contact with the connection object, thereby connecting the connection object. Are known in which terminals are electrically connected to each other (see, for example, Patent Document 1).

  In this connector, when the rotating member is closed in a state where the connection object is inserted into the connector main body, each terminal receives a pressure from the rotating member and elastically deforms, whereby the contact portion of each terminal is connected to the connection object. It moves in the direction of contact with and contacts the connection object.

  By the way, in this connector, when the rotating member is closed, the rotating member presses each terminal so that the contact portion of each terminal comes into contact with the connection object. Since each terminal is always pressed by the rotating member in the electrically connected state, each terminal is plastically deformed by this pressing, and there is a problem that connection reliability is lowered.

  Therefore, when the rotating member is rotated to a predetermined open position, each terminal is elastically deformed by being pressed by the pressing portion of the rotating member, and the contact portion provided on each terminal is opposite to the connection object. When moving in the contact direction and closing the rotating member with the connection object inserted into the connector body, each terminal is restored and the contact portion comes into contact with the connection object, so that the connection object and each terminal are A connector that is electrically connected is known.

An example of this connector is shown in FIG. In the connector, a rotating member 2 provided so as to be rotatable with respect to the connector main body 1 rotates around a rotating shaft 2a formed on one end thereof, and the rotating member 2 is moved to a predetermined open position. When each of the terminals 3 is rotated to the other end side of the rotating member 2, it is elastically deformed by being pressed toward one end side of the rotating member 2 by the pressing portion 2b provided on the other end side of the rotating member 2, thereby connecting the contact portion 3a The object 4 is moved in the anti-contact direction (upward in the figure). Further, the upper surface of the rotating shaft 2a is supported by a substantially semicircular bearing portion 3b opened downward.
JP 2006-147271 A

  However, in this connector, since the bearing portion 3b is formed so as to cover the upper surface of the rotating shaft 2a, the dimension from one end side to the other end side of the rotating member 2 is simply from the rotating shaft 2a to the terminal. Compared with the case where the dimension is up to 3, the dimension in the vertical direction of the bearing portion 3b is increased. Therefore, since the size of the connector increases with the increase in size of the rotating member 2, there is a problem that it is impossible to meet the demand for downsizing of the device.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a connector capable of reducing the dimension from one end side to the other end side of a rotating member.

  To achieve the above object, the present invention provides a connector main body in which one end of a connection object can be inserted into a predetermined position, a plurality of terminals arranged in the connector main body at intervals in the width direction, and each terminal. And a rotation member provided so as to be rotatable with respect to the connector body. When the rotation member is rotated to a predetermined open position, each terminal is pressed by the rotation member. When the contact part provided in each terminal moves in the anti-contact direction with the connection object and closes the rotating member in a state where the connection object is inserted into the connector body, In the connector in which each terminal is restored and the contact portion comes into contact with the connection object, and the connection object and each terminal are electrically connected to each other, the one end side of the rotation member can be freely rotated. Support the bearing part along the pressing direction of the pressing part It is provided in the building so.

  Accordingly, since the bearing portion is provided so as to extend along the pressing direction of the pressing portion from one end side of the rotating member, one end of the rotating member is rotated when the rotating member is rotated to a predetermined open position. There is no bearing between the side and the other end.

  According to the present invention, since the bearing portion is not interposed between the one end side and the other end side of the rotating member when the rotating member is rotated to the predetermined open position, the dimension of the bearing portion is taken into consideration. The dimension from the one end side to the other end side of the rotating member can be reduced without any problem. Therefore, the connector can be miniaturized and the demand for miniaturization of the device can be met.

When the pressing cover 40 is opened to the open position, the elastic piece 31 is elastically deformed by pressing the lower end side of the elastic piece 31 upward by the pressing cover 40. In this case, the front end side of the elastic piece portion 31 including the contact portion 31a moves upward. The size of the gap G <b> 1 between the lower end of the contact portion 31 a and the fixed piece portion 32 is formed in the same manner as the first terminal 20.

  The pressing cover 40 is made of a synthetic resin molded product, and is formed in a plate shape so as to cover the upper rear end side of the connector body 10 from above. A plurality of first insertion holes 41 through which the elastic pieces 21 of the first terminals 20 can be inserted and a plurality of elastic pieces 31 of the second terminals 30 can be inserted into the front end side of the pressing cover 40. The second insertion holes 42 are provided, and each first insertion hole 41 is provided with a rotating shaft 41a supported by the bearing portion 22a of each first terminal 20. Moreover, the 1st press part 43 which presses the elastic piece part 21 of each 1st terminal 20 below is provided in the rear end side of each 1st insertion hole 41, The press part 43 is the The pressing surface is formed to be bent forward. Further, each second insertion hole 42 is provided with a second pressing portion 42a that presses the lower end of the elastic piece portion 31 of each second terminal 30 upward when the pressing cover 40 is opened. .

  The connector configured as described above is attached to the substrate A as shown in FIGS. 6A and 6B, and the flexible circuit 100 can be inserted into and removed from the connector body 10 when the pressing cover 40 is opened. .

  In the connector, as shown in FIG. 7A, when the pressing cover 40 is rotated from the fully closed position to the opening direction, that is, forward, the pressing portion 43 becomes the upper rear end of the elastic piece portion 21 of the first terminal 20. Move forward while touching the side. Here, the distance D1 from the one end 21b-1 of the engaging portion 21b to the center of the rotating shaft 41a is longer than the distance D2 from the pressing surface of the pressing portion 43 to the center of the rotating shaft 41a. When the pressing cover 40 is rotated to the one end 21b-1 of the engaging portion 21b, the one end 21b-1 of the engaging portion 21b is pressed downward by the pressing portion 43, and the front end side of the elastic piece portion 21 (including the contact portion 21a). ) Will rise. Further, as shown in FIG. 7B, when the pressing cover 40 is further rotated forward, the pressing portion 43 of the pressing cover 40 is engaged with the engaging portion at the fully opened position (position rotated about 90 ° from the fully closed position). 21b is engaged. At that time, the engagement of the engaging portion 21b with the pressing portion 43 is transmitted to the outside through the pressing cover 40 by engaging the pressing portion 43 while the engaging portion 21b is restored upward. Further, even when the pressing cover 40 is rotated to the fully open position, each first terminal 20 is elastically deformed when the engaging portion 21 b is pressed downward by the pressing cover 40. In this case, as shown in FIG. 6A, the dimension of the gap G2 between the contact part 21a of each first terminal 20 and the fixed piece part 22 becomes larger than the thickness dimension of the flexible circuit 100, and flexible The circuit 100 can be inserted into the connector body 10. Since the bearing portion 22a is formed to extend in the vertical direction, that is, along the pressing direction (downward) of the pressing cover 40, when the pressing cover 40 is rotated to the fully opened position, one end of the pressing cover 40 is formed. The bearing portion 22a is not interposed between the side (the rotation shaft 41a) and the other end side (the pressing portion 43).

  When the pressing cover 40 is rotated to the fully open position, the lower end of the elastic piece portion 31 of each second terminal 30 is moved upward by the second pressing portion 42a of the pressing cover 40 as shown in FIG. The front end side (including the contact portion 31a) of the elastic piece portion 31 is raised by being pressed by the. In this case, the dimension of the gap G2 between the contact part 31a of each second terminal 30 and the fixed piece part 32 becomes larger than the thickness dimension of the flexible circuit 100, and the flexible circuit 100 is inserted into the connector body 10. Is possible.

  Next, when the pressing cover 40 is rotated in the closing direction after the flexible circuit 100 is inserted into the connector main body 10, each first terminal 20 is released from being pressed by the pressing cover 40 as shown in FIG. To restore. In this case, the contact portion 21 a of the elastic piece portion 21 moves downward and contacts the first electrical contact 100 a of the flexible circuit 100. Further, as shown in FIG. 8B, the contact portion 31 a of each second terminal 30 moves downward and contacts the second electrical contact 100 b of the flexible circuit 100. Thereby, the flexible circuit 100 and the board | substrate A are electrically connected via each terminal 20 and 30. FIG. In this case, since the terminals 20 and 30 are not pressed by the pressing cover 40, they are not plastically deformed. When the pressing cover 40 is closed, the rotation shaft 41 a of the pressing cover 40 comes into contact with the lower surface rear end side of the elastic piece portion 21 of each first terminal 20. Thereby, since the rear end side of the elastic piece portion 21 is restricted from elastically deforming downward, it is possible to prevent the contact portion 21a from moving upward due to elastic deformation. Therefore, the contact portion 21a is not separated from the flexible circuit 100 to cause a contact failure.

  Thus, according to the connector of the present embodiment, the bearing portion 22a that supports the rotation of the pressing cover 40 is provided on one end side of the pressing cover 40 so as to extend along the pressing direction of the first pressing portion 43. Therefore, when the pressing cover 40 is rotated to the fully open position, the bearing portion 22a is not interposed between one end side (the rotating shaft 12a) and the other end side (first pressing portion 43) of the pressing cover 40. . Therefore, since the dimension from the one end side of the pressing cover 40 to the other end side can be reduced without considering the dimension of the bearing portion 22a, the connector can be miniaturized and the demand for miniaturization of the device is met. be able to.

  Further, when the pressing cover 40 is rotated to the first terminal 20 in the opening direction, the pressing cover 40 is elastically deformed by pressing from the pressing cover 40, and when the pressing cover 40 is rotated to the fully opened position, the pressing cover 40 is restored while being restored. Since the engaging portion 21b that engages with the pressing portion 43 is provided, it is possible to confirm that the pressing cover 40 has been rotated to the fully open position by a feel at the time of the rotating operation, and there is an advantage that the operation becomes easy. is there.

  Further, when each of the first terminals 20 is closed, the lower surface rear end side of the elastic piece portion 21 comes into contact with the pressure cover 40 when the pressure cover 40 is closed, thereby restricting the elastic deformation of the elastic piece portion 21 upward on the front end side. Therefore, when the pressing cover 40 is closed, it is ensured that the contact portion 21a of each first terminal 20 is separated from the flexible circuit 100 due to elastic deformation of each first terminal 20 to cause poor contact. Can be prevented.

  In addition, the said embodiment is only one specific example of this invention, and this invention is not limited only to the said embodiment.
