  In the connector to which the flat cable is connected, a plurality of contacts that are electrically connected to a plurality of terminals arranged in the width direction of the flat cable are arranged in one direction in the housing. In order to ensure contact between the plurality of terminals of the flat cable and the plurality of contacts, the plurality of terminals of the flat cable are arranged on the plurality of contacts, and the flat cable is connected to the plurality of flat cables by the lock member (cover member). A technique for pressing toward a contact is known (see Patent Document 1).

JP 2006-66242 A (FIG. 4)

  In the above-described technique, since the cover member extends in the contact arrangement direction, the cover member is easily bent along the arrangement direction when the flat cable is pressed. For this reason, the contact pressure between the contacts arranged in the vicinity of the center in the arrangement direction and the terminals of the flat cable may be weakened, resulting in poor electrical connection between the contacts and the terminals. Further, in the above-described technique, since the shield member is assembled on the connector after the flat cable is connected, the connection work of the flat cable is complicated. Furthermore, since the shield member assembled on the connector covers only the upper part of the connector, a sufficient shielding effect cannot be obtained.

  An object of the present invention is to provide a connector capable of suppressing a contact pressure between a terminal and a contact of a flat flexible cable from being insufficient and obtaining a high shielding effect by an easy connection operation.

  The connector of the present invention is arranged in one direction on a housing in which a recess in which an end of a flat flexible cable is disposed, a conductive shell supported by the housing, and a bottom surface of the recess. A closed position that closes the recess while the contact surface is opposed to the plurality of contacts, and a contact plate having a contact surface extending in the one direction. And a cover member rotatably supported by the housing or the shell so as to be able to selectively take an open position where the recess is opened. The contact plate has a protruding piece that protrudes in parallel with a plane including the contact surface, the housing has an engagement hole that engages with the protruding piece, and the cover member has the When the projecting piece is slidable between the closed position and the engaging position where the projecting piece engages with the engaging hole with respect to the projecting direction of the projecting piece, and the cover member is in the engaging position The cover member and the shell are electrically connected by contacting each other and surround the plurality of contacts.

  According to the present invention, by moving the cover member from the closed position to the engaged position, the protruding piece protruding from the contact plate is fitted into the engagement hole of the housing, and the rigidity of the contact plate is increased. Thereby, when the contact surface of a contact plate is made to contact a flat flexible cable, it can suppress that a contact plate bends and the contact pressure of the terminal and contact of a flat flexible cable runs short. Further, since the cover member and the shell that are electrically connected to each other surround the plurality of contacts by sliding the cover member to the engagement position, a high shielding effect can be obtained with an easy connection operation.

  In the present invention, the cover member has a protrusion that does not contact the shell when in the open position and the closed position, and contacts the shell when in the engagement position. Preferably it is. According to this, the cover member and the shell can be reliably electrically connected when the cover member is in the engagement position, and the cover member can be smoothly rotated between the open position and the closed position. Can do.

  Further, in the present invention, when the cover member is in the engagement position, the contact plate enters the recess while curving in a U shape from the outlet from which the flat flexible cable is pulled out. It is preferable that the protruding piece protrudes from an end portion farthest from the outlet of the contact plate. According to this, since the contact plate has a spring property, the terminal and the contact of the flat flexible cable can be efficiently contacted.

  Furthermore, in the present invention, it is preferable that one or a plurality of the protruding pieces protrude from the vicinity of the center of the end portion of the contact plate extending in the one direction. According to this, the rigidity in one direction of the contact plate can be efficiently increased.

  In addition, in the present invention, a pair of locking surfaces are formed in the vicinity of both ends in the one direction of the housing, and the locking members are oriented in the direction of rotation when the cover member rotates toward the closed position. The cover member has a pair of hooks formed in the vicinity of both ends of the one direction in the direction opposite to the rotation direction, and when the cover member is in the closed position, The hook is disposed at a position where the contact surface does not face the locking surface, and when the cover member is at the engagement position, the hook is positioned at a position where the contact surface contacts the locking surface. Preferably they are arranged. According to this, since the contact surface and the locking surface are in contact with each other and the cover member is restricted from rotating, it is possible to prevent the cover member from being accidentally opened.

  According to the present invention, by moving the cover member from the closed position to the engaged position, the protruding piece protruding from the contact plate is fitted into the engagement hole of the housing, and the rigidity of the contact plate is increased. Thereby, when the contact surface of a contact plate is made to contact a flat flexible cable, it can suppress that a contact plate bends and the contact pressure of the terminal and contact of a flat flexible cable runs short. Further, since the cover member and the shell that are electrically connected to each other surround the plurality of contacts by sliding the cover member to the engagement position, a high shielding effect can be obtained with an easy connection operation.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1A and 1B, the connector 1 is a connector to which a flat cable 70 is connected. The flat cable 70 is a cable in which a plurality of electrical wirings are formed in a flexible resin substrate. A plurality of terminals corresponding to a plurality of electrical wirings are disposed on one surface of the end portion of the flat cable 70, and a shield surface 72 in which a part of the shield material is exposed is formed over the other surface. (See FIGS. 5 to 6). The connector 1 includes a housing 2, a shell 3, a plurality of contacts 4, and a cover member 5. In the following description, the direction in which the flat cable 70 is pulled out in the connector 1 is defined as the front (lower left direction in the figure), and the direction opposite to the front is defined as the rear. As shown in FIGS. 1 (a), 2 (a), and 2 (b), the housing 2 is a member made of resin and extends in the left-right direction (hereinafter referred to as the width direction) in FIG. The housing body 21 has a substantially rectangular parallelepiped shape, and a pair of engagement plate portions 22 arranged on both sides in the width direction of the housing body 21.

  The housing body 21 has a recess 23 extending in the width direction formed so that a corner portion at the upper front end is notched. The opening on the front side of the recess 23 serves as a drawer opening 23c from which the flat cable 70 is pulled out. A plurality of narrow grooves 23 a that extend in the front-rear direction and are arranged in the width direction are formed at the bottom of the recess 23. On the inner wall surface located at the rear end of the recess 23, two engagement holes 23b are formed in which the openings extend in the width direction and are arranged in the width direction.

  As shown in FIG. 2A, a step portion 21 a is formed at the front lower end of both side surfaces in the width direction of the housing body 21. A surface facing the lower side of the stepped portion 21a (a surface facing the rotation direction when the cover member 5 rotates from the open position toward the closed position: described later) is a locking surface 21b. As shown in FIGS. 1 (a) and 3 (c), a stepped portion 21c extending rearward is formed at the front upper end of both side surfaces of the housing body 21 in the width direction.

  As shown in FIG. 2B, the shell 3 is a metal member having a bottom plate portion 31 extending in the width direction and a pair of side walls 32 protruding upward from both ends in the width direction of the bottom plate portion 31. The bottom plate portion 31 is in contact with the bottom surface of the housing body 21. As shown in FIG. 3A, the side wall 32 is formed with a notch groove 33 extending rearward from the front end (from the left to the right in the figure). The lower end of the notch groove 33 extends linearly, and the upper end of the notch groove 33 changes the height in a step shape. The notch groove 33 is formed with a rotation part 33a, a slide part 33b, and a fixing part 33c in order from the front end that have different widths (widths of the notch groove 33) by changing the height of the upper end. The width of the rotation part 33a is the widest, the width of the slide part 33b is the narrowest, and the width of the fixed part 33c is narrower than the rotation part 33a and wider than the slide part 33b. As will be described later, as the cover member 5 opens and closes, the shaft portion 55 of the cover member 5 moves in the rotating portion 33a, the slide portion 33b, and the fixed portion 33c.

  The side wall 32 is disposed between the side surface of the housing main body 21 and the engagement plate portion 22. The engaging plate portion 22 is formed with a protruding portion 22 a that protrudes rearward, and this protruding portion 22 a is engaged with the rotating portion 33 a of the notch groove 33. Thus, the shell 3 is fixed to the housing 2 so as to cover a part of the bottom surface and the side surface of the housing main body 21.

  As shown in FIG. 2B, a pair of ground leads 34 drawn rearward is formed in the vicinity of both ends in the width direction of the rear end of the shell 3.

  As shown in FIG. 3B, the contact 4 has a contact portion 41 that is curved so as to be convex upward, and extends from the contact portion 41 toward the front (left side in the figure), and then from the bottom to the rear. It has a spring portion 42 that is curved toward the right (in the drawing in the drawing) and extends further rearward, and a signal lead 43 that is drawn from the rear end of the spring portion 42 to the lower surface of the housing body 21. . The spring portions 42 of the plurality of contacts 4 are disposed in the plurality of narrow grooves 23a formed on the bottom surface of the recess 23 of the housing body 21, and the contact portions 41 protrude upward from the openings of the narrow grooves 23a. Thus, the contact portions 41 of the contacts 4 are arranged in one direction on the bottom surface of the recess 23. When the spring portion 42 is elastically deformed, the contact portion 41 can be displaced in the vertical direction.

  As shown in FIG. 2B, the plurality of signal leads 43 are arranged in the width direction between the pair of ground leads 34. The connector 1 is mounted on the substrate by electrically connecting the ground lead 34 and the signal lead 43 to a land formed on the substrate surface (not shown) by solder bonding.

  As shown in FIGS. 1A and 1B, the cover member 5 is a metal member that opens and closes the recess 23 when the flat cable 70 is attached and detached. Specifically, the cover member 5 selectively rotates between the open position (see FIG. 4) for opening the recess 23 and the closed position (see FIG. 5) for closing the recess 23 by rotating with respect to the shell 3. I can take it. Further, the cover member 5 can selectively take a closed position and an engagement position (see FIG. 6) that engages with the housing body 21 by sliding in the front-rear direction with respect to the shell 3. The cover member 5 has an upper plate portion 51, a contact plate portion 52, and a pair of side plate portions 54. The upper plate portion 51 has a planar shape extending in the width direction that can cover the upper surface of the housing body 21.

  As shown in FIGS. 1 (a) and 3 (b), the contact plate portion 52 is directed from the front end of the upper plate portion 51 defining the lead-out port 23c of the flat cable 70 toward the housing body 21 (concave portion 23). It extends in parallel with the upper plate portion 51 while curving in a U-shape. As shown in FIG. 5B, the lower surface of the contact plate portion 52 is a contact surface 52 a that contacts the shield surface 72 of the flat cable 70. Two projecting pieces 53 that project further rearward are formed at the center in the width direction of the rear end of the contact plate 52 (the end farthest from the outlet 23c).

  As shown in FIG. 2A, the pair of side plate portions 54 are formed at both ends in the width direction of the upper plate portion 51, and are located on both sides in the width direction of the housing body 21. As shown in FIGS. 2B and 3C, a shaft portion 55 is formed at the rear end of each side plate portion 54 so as to protrude outward in parallel with the plane including the contact plate portion 52. Yes. As shown in FIG. 3A, the shaft portion 55 has a substantially rectangular cross section extending in the left-right direction in the drawing, and the angle of the contact plate portion 52 and the longitudinal direction of the cross section of the shaft portion 55. The angle matches. Each shaft portion 55 is disposed in a notch groove 33 formed in the side wall 32 of the shell 3.

  The width of the turning portion 33 a of the notch groove 33 is equal to or greater than the thickness of the cross section of the shaft portion 55 in the longitudinal direction. Further, the width of the slide portion 33b and the fixed portion 33c is less than the thickness in the longitudinal direction of the cross section of the shaft portion 55 and is equal to or greater than the thickness in the width direction. For this reason, the cover member 5 including the shaft portion 55 can be turned only when the shaft portion 55 is located in the turning portion 33a. Further, the shaft 55 is disposed only when the longitudinal direction of the cross section is along the front-rear direction, that is, when the upper plate portion 51 and the contact plate portion 52 are disposed along the front-rear direction. The cover member 5 including the portion 55 can slide between the rotating portion 33a and the fixed portion 33c.

  In addition, since the upper board part 51 and the contact board part 52 are connected via the curved part, the contact board part 52 has springiness. When the cover member closes the concave portion 23, the shaft portion 55 is always urged upward (in the direction in which the cover member 5 rotates so as to open the concave portion 23) due to the spring property of the contact plate portion 52. Comes into contact with the upper end of the notch groove 33. When the shaft portion 55 is in the rotating portion 33a and the fixed portion 33c, the shaft portion 55 engages with the stepped portion at the upper end of the rotating portion 33a and the fixed portion 33c, so that the shaft portion 55 cannot slide. In order to make the shaft portion 55 slidable, the user pushes the cover member 5 downward so that the shaft portion 55 is separated from the stepped portions at the upper ends of the rotating portion 33a and the fixing portion 33c.

  Thus, when the shaft portion 55 is located in the rotation portion 33a, the cover member 5 can be rotated with respect to the shell 3. As a result, the cover member 5 has an open position that opens the recess 23 when the contact plate 52 is separated from the recess 23 and a closed position that closes the recess 23 when the contact plate 52 is disposed in the recess 23. It can be taken selectively. Further, when the cover member 5 is rotated so that the contact plate portion 52 is disposed in the recess 23, the shaft portion 55 is disposed so that the longitudinal direction of the cross section is along the front-rear direction, and the cover member 5 is the shell. 3 can slide in the front-rear direction (the extending direction of the notch groove 33). As a result, the cover member 5 can selectively take a closed position where the shaft portion 55 is positioned at the rotating portion 33a and an engagement position where the shaft portion 55 is positioned at the fixed portion 33c.

  As shown in FIGS. 5 and 6, when the cover member 5 is slid from the closed position to the engaged position, the two protruding pieces 53 of the cover member 5 are respectively inserted into the two engaging holes 23 b of the housing body 21. And both fit. As a result, the vicinity of the center in the width direction at the rear end of the contact plate portion 52 is fixed to the housing body 21, and the rigidity of the contact plate portion 52 in the width direction is increased.

  As shown in FIG. 2, a hook portion 54 a that extends downward and bends inward is formed in the vicinity of the front end portion of each side plate portion 54 related to the cover member 5. The inner surface (the surface facing the direction opposite to the rotation direction when the cover member 5 rotates from the open position toward the closed position) of the hook portion 54a is a contact surface 54b. As shown in FIG. 5, the hook portion 54 a is positioned in front of the housing body 21 when the cover member 5 is in the closed position, and the cover member 5 is in the closed position as shown in FIGS. 2 (a) and 6. The pair of hook portions 54a formed in the vicinity of the front end portion of the cover member 5 is moved from the front to the rear of the housing body 21, and the contact surface 54b of the hook portion 54a is moved to the housing. It contacts the locking surface 21 b of the main body 21. Thereby, it can prevent that the cover member 5 opens accidentally by having pulled up the connected flat cable 70 upwards.

  As shown in FIG. 3C, in the vicinity of the hook portion 54a in each side plate portion 54, a small protrusion 54c having a circular plane and protruding inward is formed. As shown in FIG. 5, the small protrusion 54 c is located in front of the housing body 21 when the cover member 5 is in the closed position. As shown in FIG. 6, when the cover member 5 is slid from the closed position to the engaged position, the small protrusion 54c gets over the front corner of the housing body 21 and is disposed in the stepped portion 21c. At this time, since the user who has slid the cover member 5 can obtain a click feeling, the user can confirm that the cover member 5 has reached the engagement position.

  In the vicinity of the center of each side plate portion 54 in the longitudinal direction, a projection 54d having a circular plane and protruding outward is formed. As shown in FIGS. 4 and 5, the protrusion 54 d is separated from the side wall 32 of the shell 3 when the cover member 5 is in the open position and the closed position. As shown in FIG. 6, the protrusion 54 d comes into contact with the side wall 32 of the shell 3 when the cover member 5 slides from the closed position and moves to the engaged position. Thereby, the cover member 5 and the shell 3 are electrically connected. At this time, since the shell 3 and the cover member 5 that are electrically connected to each other surround the plurality of contacts 4, a high shielding effect can be obtained.

  Connection work of the flat cable 70 to the connector 1 will be described. First, as shown in FIG. 4, the cover member 5 is rotated to the open position so that the recess 23 is opened. And the edge part of the flat cable 70 is arrange | positioned in the recessed part 23 opened. At this time, the plurality of terminals of the flat cable 70 are arranged so as to come into contact with the contact portion 41 of the contact 4 protruding from the narrow groove 23 a formed on the bottom surface of the recess 23.

  In this state, the cover member 5 is rotated from the open position to the closed position. When the cover member 5 is rotated to the closed position, as shown in FIG. 5, the contact plate portion 52 of the cover member 5 is disposed in the recess 23, and the contact surface 52a of the contact plate portion 52 is flat cable. The flat cable 70 is pressed toward the bottom surface of the recess 23 while being in contact with the shield surface 72 of the 70. Thereby, the contact plate portion 52 and the shield surface 72 are electrically connected, and the contact portion 41 of the contact 4 facing the terminal of the flat cable 70 is electrically connected while being in contact with each other. At this time, the cover member 5 (the curved portion connecting the upper plate portion 51 and the contact plate portion 52) and the spring property of the spring portion 42 of the contact 4 are brought into contact with each other with an appropriate pressure.

  Furthermore, the shaft portion 55 can be slidable by pressing the cover member 5 in the closed position downward so that the shaft portion 55 is spaced apart from the upper ends of the rotating portion 33a and the fixed portion 33c and contacts the lower end. Become. In this state, the cover member 5 is slid to the engagement position. At this time, as shown in FIG. 6, the two protruding pieces 53 protruding from the contact plate portion 52 of the cover member 5 are inserted into the two engaging holes 23 b of the housing main body 21, respectively, and both are fitted. Thereby, the vicinity of the center in the width direction at the rear end of the contact plate portion 52 is fixed to the housing body 21. Further, a pair of hook portions 54 a formed in the vicinity of the front end portion of each side plate portion 54 of the cover member 5 move from the front to the rear of the housing body 21, and the contact surface 54 b of the hook portion 54 a is It contacts the locking surface 21b. Further, the small protrusion 54c is disposed in the stepped portion 21c so as to get over the front corner of the housing body 21 when the cover member 5 is slid from the closed position to the engaged position.

  Further, the projecting portions 54 d formed on the side plate portions 54 of the cover member 5 come into contact with the side walls 32 of the shell 3, whereby the cover member 5 and the shell 3 are electrically connected. At this time, the shell 3 and the cover member 5 that are electrically connected to each other surround the plurality of contacts 4. Thus, the connection work of the flat cable 70 to the connector 1 is completed.

  As described above, according to the connector 1 of the present embodiment, by moving the cover member 5 from the closed position to the engaged position, the two protruding pieces 53 protruding from the contact plate portion 52 are formed in the two positions of the housing body 21. Since the engagement holes 23b are respectively fitted, the rigidity of the contact plate portion 52 is increased. Thereby, when the contact surface 52a of the contact plate portion 52 is brought into contact with the flat cable 70, the contact plate portion 52 is prevented from being bent in the width direction, and the terminal of the flat cable 70 and the contact portion 41 of the contact 4 Insufficient contact pressure can be prevented. In addition, since the cover member 5 and the shell 3 that are electrically connected to each other surround the plurality of contacts 4 by sliding the cover member 5 from the closed position to the engaged position, a high shielding effect can be achieved with an easy connection operation. Can be obtained.

  Further, the projections 54d formed on the side plate portions 54 of the cover member 5 are separated from the side wall 32 of the shell 3 when the cover member 5 is in the open position and the closed position, and the cover member 5 is in the closed position. When the cover member 5 and the shell 3 are electrically connected to each other when the projection 54d comes into contact with the side wall 32 of the shell 3 and the cover member 5 and the shell 3 are electrically connected to each other. While being able to make an electrical connection reliably, the cover member 5 can be smoothly rotated between the open position and the closed position.

  Further, the contact plate portion 52 extends in parallel with the upper plate portion 51 while curving in a U shape from the front end of the upper plate portion 51 that defines the outlet 23c of the flat cable 70 toward the housing main body 21 side. Therefore, the contact plate portion 52 has a spring property, and the terminal of the flat cable 70 and the contact portion 41 of the contact 4 can be efficiently contacted.

  In addition, since the two protruding pieces 53 protrude from the center in the width direction of the rear end of the contact plate portion 52, the rigidity of the contact plate portion 52 can be increased efficiently.

  Further, by sliding the cover member 5 from the closed position to the engaged position, the contact surfaces 54b of the pair of hook portions 54a formed in the vicinity of the front end portion of the cover member 5 become the locking surfaces 21b of the housing body 21. Abut. Thereby, it can prevent that the cover member 5 opens accidentally by having pulled up the connected flat cable 70 upwards.

When the cover member is slidably supported by the housing, the cover member and the shell may be integrated and slide between the closed position and the engaged position.

  In the above-described embodiment, the protrusions 54d formed on the side plate portions 54 of the cover member 5 are separated from the side wall 32 of the shell 3 when the cover member 5 is in the open position and the closed position. When the cover member 5 slides from the closed position and moves to the engagement position, the projection 54d comes into contact with the side wall 32 of the shell 3 so that the cover member 5 and the shell 3 are electrically connected. If the cover member and the shell are electrically connected when the cover member is in the engaged position, the cover member and the shell may be electrically connected by another configuration. For example, the cover member and the shell 3 may always be electrically connected regardless of the position of the cover member. In this case, from the viewpoint of smoothly rotating the cover member, it is preferable to perform electrical connection at a place where the cover member is pivotally supported by the shell.

  Furthermore, in the above-described embodiment, the contact plate portion 52 is configured to extend in parallel with the upper plate portion 51 while curving in a U shape from the front end of the upper plate portion 51 toward the housing main body 21 side. The upper plate portion may also serve as the contact plate portion. In this case, the bottom surface of the upper plate portion serves as a contact surface, and the protruding portion protrudes from the rear end of the upper plate portion.
