Description

  The present invention relates to a connection structure between a flat circuit body and a connector that electrically connects the flat circuit body and the connector.

Conventionally, as a connection structure between a flat circuit body such as a flexible printed circuit (FPC) or a flexible flat cable and a connector, a flat circuit is formed by inserting an end of the flat circuit body into a connector main body of the connector. The body and the connector are electrically connected.
For example, in Patent Document 1, a guide member (block) that guides insertion into a connector body is attached to the flat circuit body, and the end portion of the flat circuit body is secured by locking the guide member and the connector body. A connection structure between a flat circuit body fixed in the connector body and the connector is described.

Each guide portion 37 includes a latch member 40 assembled to the latch member assembling portion 36, until the circuit body end 10 a starts to be inserted into the connector main body 30 until it is locked in the connector main body 30. A guide surface 37a (see FIG. 1) for guiding the movement of the locking member 40 is provided.

  The member locking portion 38 is a protruding portion that protrudes from the upper surface of the connector main body 30, and is a portion that locks a later-described member locked portion 61 of the guide member 50.

  Such a connector main body 30 is fixed to a substrate (not shown) or the like to be attached by fixing brackets 80 and 80.

The locking member 40 is made of an insulating material such as a synthetic resin, and is assembled to the connector main body 30 so that the circuit body locking portions 43 and 43 can be engaged with and disengaged from the circuit body locked portions 13 and 13.
The locking member 40 includes a member main body 41, a pair of guided portions 42 and 42, and circuit body locking portions 43 and 43 provided at two positions of the member main body 41.

Each guided portion 42 is a portion that is provided at each end in the longitudinal direction of the member main body 41 and receives a force that moves downward by being urged against the guide surface 37a using an elastic force.
Each guided portion 42 has a pair of elastic arm portions 42 a and 42 a that are provided so that the free end side thereof can be elastically bent and deformed toward the inside of the locking member 40 and is biased by the guide surface 37 a.
Each elastic arm part 42a is provided with a biasing protrusion 42b that protrudes toward the outside of the locking member 40 at the tip part.
The biasing protrusion 42b is biased to the guide surface 37a, and the bending load of the elastic arm portion 42a is applied to the guide surface 37a, so that the locking member 40 receiving the reaction force is automatically moved downward. It is like that.
That is, the locking member 40 automatically moves downward using elastic force to fit each circuit body locking portion 43 into the hole of each circuit body locked portion 13 from above. Yes.

  The circuit body locking portion 43 is a portion for locking the circuit body locked portion 13. The circuit body locking portion 43 is a convex portion that is fitted into the hole of the circuit body locked portion 13.

The circuit body locking portion 43 is formed with a sliding contact surface 43a on which the circuit body end portion 10a is slidably contacted.
The sliding contact surface 43a is formed on the front surface of the circuit body locking portion 43 so as to be inclined upwardly from the lower end toward the upper side. When the circuit body end portion 10a is brought into sliding contact with the sliding contact surface 43a, the locking member 40 is moved upward while the pair of guided portions 42 are guided by the guide surface 37a. As a result, the circuit body end 10 a is inserted into the connector body 30 without being blocked by the circuit body locking portion 43.

Next, the guide member 50 will be described.
The guide member 50 includes a guide main body 60 and a cover member 70 that is a separate member from the guide main body 60.
