Description

  The present invention relates to a connector for connecting, for example, a flexible printed circuit (FPC) or a flexible flat cable (FFC).

  Conventionally, as this type of connector, there are a connector main body in which one end of an object to be connected such as FPC or FFC can be inserted into a predetermined position, and a plurality of elastically deformable members arranged in the connector main body at intervals in the width direction. And a slide member that is movably attached to the connector body in the front-rear direction. When the slide member is pulled forward, the connection object can be inserted into the connector body, and the connection object is inserted into the connector body. When the slide member is moved rearwardly, there is known one in which each terminal and the connection object are pressed against each other by the slide member (see, for example, Patent Document 1).

Further, as another connector, a rotation member having one end rotatably attached to the connector main body is provided. When the rotation member is rotated upward, the connection object can be inserted into the connector main body. When the rotating member is rotated downward in a state where it is inserted into the connector main body, there is known one in which each terminal and a connection object are pressed against each other by the rotating member (see, for example, Patent Document 2). .

  However, in the former connector, each terminal is pressed toward the connection object by the slide member while moving the slide member. Therefore, as the number of terminals increases, the force required to press each terminal also increases. For this reason, the operability of the slide member at the time of connection is lowered, and there is a problem that connection failure is likely to occur due to insufficient movement of the slide member to the terminal pressing side. Moreover, in the latter connector, each terminal is pressed to the connection object side by rotating the rotating member downward, so that the force is applied to the terminal pressing side as compared with the one using the slide member. Although it is easy to add, when an upward force is applied to the connected object to be connected, there is a problem that the rotating member is rotated upward and the connected state is easily released.

  The present invention has been made in view of the above problems, and the object of the present invention is to reliably insert the connection object into the connector body with a small insertion force, and to connect the connection object and the terminal. An object of the present invention is to provide a connector whose connection state is not easily released.

  In order to achieve the above object, the present invention provides a connector main body in which a connection object can be inserted in the front-rear direction, elastically deformable terminals arranged in the connector body at intervals in the width direction, and a connector main body. And a slide member movably provided in the front-rear direction. In the connector in which each terminal is brought into contact with a connection object inserted in the connector body, the slide member is moved in the front-rear direction to the slide member. If it does, the terminal guide part which elastically deforms a terminal to the contact direction opposite side with a connection target object by contact | abutting with a terminal is provided.

  Thereby, when the slide member is moved in the front-rear direction, the terminal guide portion of the slide member abuts on the terminal, and the terminal guide portion elastically deforms the terminal in the direction opposite to the contact direction with the connection target. The contact pressure of the terminal is not applied to the connection object when the object is inserted.

  Since the contact pressure of the terminal is not applied to the connection object when the connection object is inserted, the connection object can be reliably inserted into the connector body with a small insertion force. Therefore, even when the number of terminals is large, the connection object can be reliably inserted to a predetermined position in the connector main body, and poor connection can be effectively prevented. In this case, even when an upward force is applied to the connection object, the connection object does not rotate upward, so that the connection state between the connection object and the terminal is not easily released. There are advantages.

  The slide member 50 is made of a synthetic resin molded product, and includes an upper surface portion 51 disposed in front of the upper portion of the connector main body 10, a pair of side surface portions 52 extending rearward from both widthwise ends of the upper surface portion 51, and the side surface portions 52. Each of the movable parts 53 extends forward from the rear end, and a pair of operation parts 54 are provided at the distal ends of the movable parts 53. The upper surface portion 51 is formed so as to extend in the width direction of the connector body 10, and terminal guide portions 51 a for guiding the inclined portions 21 b of the first terminals 20 upward are provided on one end side and the other end side in the width direction, respectively. It has been. In this case, each terminal guide 51a is inclined so as to face obliquely upward toward the rear.

Further, the side surface portion 52 and the movable portion 53 are formed so as to be substantially U-shaped, and the movable portion 53 is formed so as to be elastically deformable in the width direction of the engagement hole 13a. First and second locking portions 53a and 53b that can be locked to the front end of the long hole 13b are provided on the side surface of the movable portion 53 at two front and rear portions, respectively, and when the slide member 50 is moved rearward, the first engagement is achieved. When the stop portion 53a is locked to the front end portion 13c of the long hole 13b and the slide member 50 is moved forward, the second lock portion 53b is locked to the front end portion 13c of the long hole 13b. Each operation portion 54 protrudes outward in the width direction of the slide member 50 and is formed so as to be simultaneously graspable with a fingertip from both sides in the width direction.

  When the cable 1 is connected to the connector configured as described above, the respective operation portions 54 of the slide member 50 are arranged inward in the width direction with the slide member 50 positioned forward as shown in FIG. 9A. To release the locking between the second locking portion 53b of each movable portion 53 and the front end of the long hole 13b, and as shown in FIG. 10 (a), the terminal guide portion 51a of the slide member 50 comes into contact with the inclined portion 21b of each first terminal 20, and each first terminal 20 is inclined by the inclination of the terminal guide portion 51a. The inclined portion 21b is guided upward. Thereby, as shown in FIG. 10B, the elastic piece portion 21 of each first terminal 20 is elastically deformed upward, and the contact portion 21a of each first terminal 20 is inserted into the connector body 10. The cable 1 moves upward from the upper surface of the cable 1, and the cable 1 is inserted without receiving contact pressure from each first terminal 20. At that time, the contact portions 42a of the third terminals 40 are pressed against the lower surface of the cable 1 while elastically deforming the elastic piece portions 42 downward, and the third terminals 40 contact the ground conductive portions 4 of the cable 1. Connected. Further, when the slide member 50 moves to the predetermined rear position, the first locking portion 53a of each movable portion 53 is locked to the front end portion 13c of the long hole 13b, and the forward movement of the slide member 50 is restricted. For this reason, the slide member 50 does not move forward even if a backward pressing force is not applied to the slide member 50. Next, after the cable 1 is inserted to a predetermined position in the connector main body 10, each operation portion 54 of the slide member 50 is pressed toward the inner side in the width direction, whereby the first locking of each movable portion 53 is performed. When the engagement between the portion 53a and the front end portion 13c of the long hole 13b is released, the terminal guide portion 51a of the slide member 50 is pressed forward by the elasticity of the elastic piece portion 21 of each first terminal 20, and FIG. The slide member 50 moves forward as shown in FIG. Thereby, the contact between the terminal guide portion 51a of the slide member 50 and the inclined portion 21b of each first terminal 20 is released, and the elastic piece portion 21 of each first terminal 20 is elastically deformed downward, and each The contact portion 21 a of the first terminal 20 is in pressure contact with the upper surface of the cable 1, and each first terminal 20 is connected to each signal line conductive portion 3 of the cable 1.

  As described above, according to the connector of the present embodiment, when the slide member 50 is moved rearward, each first terminal 20 is brought into contact with the terminal guide portion 51 a of the slide member 50 and each first terminal 20. Since the elastic piece 21 is elastically deformed in the direction opposite to the contact direction with the cable 1, the contact pressure of each first terminal 20 is not applied to the cable 1 when the cable 1 is inserted, and the cable 1 is small. It can be reliably inserted into the connector main body 10 with the insertion force. Accordingly, even when the number of the first terminals 20 is large, the cable 1 can be surely inserted to a predetermined position in the connector main body 10, and connection failure can be effectively prevented. In this case, even when an upward force is applied to the cable 1, the slide member 50 does not rotate upward, so that the connection state between the cable 1 and the terminals 20, 30, and 40 is easily released. There is an advantage that there is nothing.

  Further, since the terminal guide portion 51a is formed so that the surface inclined so as to face upward with respect to the moving direction of the slide member 50 is in contact with each first terminal 20, the elastic piece portion of each first terminal 20 is provided. The terminal guide 51a of the slide member 50 can be pushed forward by the elasticity of 21, and the slide member 50 can be reliably moved forward after the cable 1 is inserted.

  Further, when the slide member 50 is moved to a predetermined rear position, the first locking portion 53a of the slide member 50 is locked to the front end portion 13c of the long hole 13b of the connector body 10, and the slide member 50 is moved forward. Therefore, even if no pressing force is applied to the slide member 50 backward, the slide member 50 does not move forward, and the cable 1 can be inserted very easily. In this case, when each operation portion 54 of the slide member 50 is pressed inward, the lock between the first locking portion 53a and the front end portion 13c of the long hole 13b is released. The forward movement restriction can be easily released, and the slide member 50 can be reliably moved to a predetermined position forward.

  In addition, the slide member 40 is provided with a movable portion 53 that can be elastically deformed in the width direction of the connector body 10 by operating each operation portion 54, and the movable portion 53 can be locked to the front end portion 13 c of the long hole 13 b of the connector body 10. Since the first locking portion 53a is provided, the locking and unlocking operations of the first locking portion 53a can be easily performed by elastic deformation of the movable portion 53, and the operability can be improved. it can.

  Furthermore, the first and second terminals 20 and 30 that contact the signal line conductive portion 3 of the cable 1 and the third terminal 40 that contacts the ground conductive portion 4 of the cable 1 are provided, and the terminal of the slide member 50 is provided. By providing the guide portion 51 a so as to correspond only to the first terminal 20 disposed to face the third terminal 40, the contact pressure of the third terminal 40 is not applied to the contact position with the cable 1. Since only the first terminal 20 to which the contact pressure of the third terminal 40 is applied is elastically deformed by the terminal guide portion 51a of the slide member 50 except for the second terminal 30, the force required to move the slide member 50 is increased. The slide member 50 can be operated smoothly without becoming unnecessarily large.

  In the above embodiment, the cable 1 is shown in which a plurality of ground conductive portions 4 are provided at intervals in the width direction on one end side and the other end side in the width direction of the other surface of the cable body 2. You may make it connect the cable which formed the electroconductive part for grounds over the full width of the other side of 2.
