Abstract

A connector capable of securely cutting off electromagnetic wave from the outside even at the rotating portion of an open/close member and preventing the reliability of connection from being lowered even when a connected member is conducted to a gland part on the outside. When the open/close member (30) is rotated to a closed position, an elastically deformable shield member (40) is pressed by the open/close member (30) to pressingly come into contact with a flexible circuit (1). Accordingly, the shield member (40) must not be formed so as to avoid the rotating portion of the open/close member (30), and even at the rotating portion of the open/close member (30), the electromagnetic wave from the outside can be securely cut off by the shield member (40). Also, since a contact pressure on the flexible circuit (1) by the pressing of a pressing member (31) can be imparted to the shield member (40), the contact pressure is not lowered even if the connector is used for a long period.

Connectors

Technical field

[0001] The present invention relates to, for example, a flexible printed circuit (FPC) and a flexible flat cable.

The present invention relates to a connector for connecting (FFC) or the like.

Background art

Conventionally, as this type of connector, there are a connector main body formed such that one end of a connection object such as an FPC or FFC (hereinafter referred to as a flexible circuit) can be inserted into the front side, and a width of the connector main body. It is known that a plurality of terminals arranged in a direction are arranged so that a flexible circuit inserted into the connector body is brought into contact with one end side of each terminal (for example, see Patent Document 1).

[0003] This connector includes an opening / closing member that is rotatably provided on the connector body. When the opening / closing member is rotated to a predetermined open position, the flexible circuit can be inserted into and removed from the connector body, and the flexible circuit is attached to the connector body. When the open / close member is rotated to the predetermined closed position in the inserted state, the flexible circuit and each terminal are pressed against each other, and the connection of the flexible circuit is completed.

By the way, in the conventional connector, the force that sometimes covers the connector body with a metal shell for blocking electromagnetic waves from the outside. In this case, in order to avoid interference between the opening and closing member and the shell, the opening and closing member The rotating part of the can not be covered with a shell, so there was a problem that EMI (Electro Magnetic Interference) was not enough. In addition, when the ground conductive part of the flexible circuit is brought into contact with the shell and the shell is connected to the ground part of the substrate, the shell is provided with a contact part that is elastically deformed by contact with the flexible circuit. Only the elastic force reduces the contact reliability of the ground in long-term use, where the contact pressure tends to decrease and continuity is likely to occur.

It is provided at intervals. A groove 10c into which the shield member 40 is press-fitted is provided between the upper surface side and the bottom surface side of the terminal hole 10b, and the groove 10c is opened to the front of the connector body 10 by force. Further, an engagement groove 13 a for engaging the opening / closing member 30 is provided on the back surface of each side surface portion 13.

Each terminal 20 also has a conductive metal plate force, and is held by being press-fitted into each terminal hole 10b of the connector body 10 from the back side. One end of each terminal 20 is provided with a fixed piece 21 and an elastic piece 22 that extend in a bifurcated forward direction with a space in the up-down direction. In addition, the inertia piece portion 22 is provided so as to be positioned on one surface side (lower surface side) of the flexible circuit 1, and the fixed piece portion 21 is opposed to the inertia piece portion 22 with the shield member 40 therebetween. It is provided. The fixed piece portion 21 extends in the front-rear direction along the upper surface portion 11 of the connector main body 10, and the tip end side thereof projects forward from the terminal hole 10b. In addition, a locking portion 21 a that locks the opening / closing member 30 protrudes downward from the front end side of the fixed piece portion 21. The elastic piece portion 22 is formed so as to be elastically deformable in the vertical direction, and a contact portion 22a that comes into contact with the contact of the flexible circuit 1 protrudes upward from the tip side thereof. The other end side of each terminal 20 extends in the vertical direction along the back surface of the connector body 10, and the back side force of the connector body 10 is also exposed to the outside. Further, a connection portion 23 connected to a substrate (not shown) is provided on the other end side of each terminal 20, and the connection portion 23 is formed so as to extend rearward from the lower end cover of the terminal 20.

The opening / closing member 30 is made of a synthetic resin molded product, and is formed in a substantially L shape so as to cover the upper surface side and the rear surface side of the connector body 10. A plurality of terminal through holes 30a through which the fixing pieces 21 of the respective terminals 20 are inserted are provided at equal intervals in the width direction on the front end side of the opening / closing member 30, and a shield member is provided at one end side of each terminal through hole 30a. A pressing portion 31 that presses 40 downward is provided. The pressing portion 31 is disposed between the fixed piece portion 21 of the terminal 20 and the shield member 40, and is moved in the front-rear direction by being locked to the locking portion 21a of the fixed piece portion 21 and the front end of the upper surface portion 11. It is regulated. In this case, the pressing portion 31 has a vertical dimension when the opening / closing member 30 is in the open position (a position where the upper surface of the opening / closing member 30 is approximately 45 ° with respect to the horizontal direction). The distance between the fixed piece 21 and the shield member 50 is the dimension in the vertical direction when the opening / closing member 30 that is smaller than the distance between and the opening / closing member 30 is in the closed position (the position where the upper surface of the opening / closing member 30 is parallel to the horizontal direction). The cross section is formed to be longer in one direction so as to be larger. Further, a cover portion 32 that covers the other end side of each terminal 20 is provided on the other end side of the opening / closing member 30, and when the opening / closing member 30 is rotated to the closed position, the cover portion 32 is positioned on the back side of the connector body 10. It ’s going to be. In this case, when the other end side of each terminal 20 is covered by the cover part 32, the connection part 23 of each terminal 20 is located in the notch 32a provided at one end of the cover part 32, and the inner surface of the cover part 32 The protrusion 32b provided on the side engages with the engagement groove 13a of the connector body 10. In addition, there is an open / close between the top and back sides of the open / close member 30. When the member 30 is rotated to the open position, a flat portion 33 that is substantially parallel to the surface of the board (the surface to which the connector main body is attached) is provided. Is arranged.

[0016] The shield member 40 also has a conductive metal plate force extending in the width direction of the connector main body 10, and the rear end side is also pressed forward into the groove 10c of the connector main body 10 so that a vertical force is applied to the connector main body 10. It is mounted so as to be elastically deformable. In this case, the shield member 40 is positioned on the other surface side (upper surface side) of the flexible circuit 1, and an inclined portion 41 that is bent obliquely upward is provided on the front end side thereof. Both ends of the shield member 40 in the width direction are formed in a substantially L shape so as to cover the front end side of the side surface portion 13 of the connector body 10, and ground connection portions 42 connected to a board (not shown) are formed on the lower end side thereof. Is provided.

The connector configured as described above is assembled with the opening / closing member 30 in the open position as shown in FIG. At that time, the flat portion 33 of the opening / closing member 30 is sucked by a component holder (not shown) to be conveyed to a mounting position of a substrate (not shown). Further, when the connector is mounted on the board, the connection part 23 of each terminal 20 and the connection part 42 of the shield member 40 are connected to the board by soldering with the opening / closing member 30 in the open position. At that time, since the other end side of each terminal 20 is not covered with the cover portion 32 of the opening / closing member 30, the cover portion 32 does not hinder the soldering operation.

Next, after the connector is mounted on the substrate, one end side of the flexible circuit 1 is inserted into the opening 10a, and the opening / closing member 30 is rotated to the closed position as shown in FIG. While being in contact with the fixed piece portion 21 of the terminal 20, it rotates integrally with the opening / closing member 30, and the shield member 40 is pressed downward by the pressing portion 31. As a result, the front end side of the shield member 40 is elastically deformed downward and pressed against the upper surface (ground side) side of the flexible circuit 1, and the lower surface (signal line side) of the flexible circuit 1 is moved to the movable piece 22. Press contact and flexible circuit 1 is connected. At this time, since the flexible circuit 1 positioned below the rotating portion of the opening / closing member 30 is covered with the shield member 40, electromagnetic waves from the outside are also blocked at the rotating portion of the opening / closing member 30. Further, since the shield member 40 is pressed by the pressing portion 31 of the opening / closing member 30 and press-contacts the flexible circuit 1, a contact pressure to the flexible circuit 1 due to the pressing of the pressing portion 31 is applied to the shield member 40. As described above, according to the connector of the present embodiment, when the opening / closing member 30 is rotated to the closed position, the elastically deformable shield member 40 is pressed against the flexible circuit 1 by being pressed by the opening / closing member 30. Therefore, it is not necessary to form the shield member 40 so as to avoid the rotating portion of the opening / closing member 30. Therefore, the electromagnetic wave from the outside can be surely blocked by the shield member 40 even at the rotating portion of the opening / closing member 30, and EMI countermeasures can be strengthened. In addition, since the contact pressure to the flexible circuit 1 due to the pressing of the pressing portion 31 can be applied to the shield member 40, the connection reliability of the ground is improved so that the contact pressure does not decrease even in long-term use. Can do.

In addition, a pressing portion 31 that rotates integrally with the opening / closing member 30 and presses the shield member 40 while being in contact with the fixed piece portion 21 between the fixed piece portion 21 and the shield member 40 of each terminal 20. Since it is provided, it is possible to simplify the structure in which the rotating part of the opening / closing member 30 does not need to be provided separately from the pressing part 31.

[0021] Furthermore, since the ground connection portion 42 that can be connected to the external ground portion is provided in the shield member 40, the shield member 40 can be used not only as an electromagnetic wave shielding member but also as a ground connection member. And the number of parts can be reduced.

[0022] When the opening / closing member 30 is rotated to the closed position, the other end side of each terminal 20 is covered by the cover portion 32 provided on the opening / closing member 30, so that the other end side of each terminal 20 is externally connected to the other end side. It is possible to reliably prevent the short circuit of the terminal 20 due to adhesion of a conductive material such as a metal piece to which dust or dust does not adhere. In this case, since the cover part 32 is provided on the opening / closing member 30, it is not necessary to install a force bar that increases the number of parts compared to the case of using a cover made of another part. There are advantages.

[0023] Further, when the opening / closing member 30 is rotated to the open position, the planar portion 33 provided on the opening / closing member 30 is substantially parallel to the mounting target surface of the connector body 10. The connector body 10 can be held in parallel to the mounting target surface by being attracted in the direction perpendicular to the mounting target surface by the product holder, which is extremely advantageous when mounted on a board.
