The present invention relates to the technical field of a connector, and particularly to a connector having an automatic locking structure for latch-locking a flat lead wire.

Traditional wire-to-board connectors are configured as connecting elements that electrically connect the wires to the circuit board, the advantage of which is that they need to be solder-sealed onto the circuit board using a substantive soldering connection method. There is no such thing, and the user can realize the electrical connection effect by simply inserting and removing it.

Various connection methods have been developed so far in order to stably contact the connector and the lead wire. For example, an automatic latch lock method that can easily connect the connector and the lead wire to prevent them from falling off can be mentioned. This method can automatically latch lock in the process of inserting the lead wire into the connector as in the above operation, and it is possible to maintain the connection between the connector and the lead wire, but the tradition of having an automatic latch lock. Such connectors are not suitable for thinning applications due to the complexity of the automatic latch lock structure and the thicker thickness.

Since it can be restricted to be inverted, it is an object of the present invention to provide a lid that can be inverted so as not to pinch and push the flat lead wire.

A ninth object of the present invention is to provide a connector with an automatic locking structure described above, which can form a chamfer angle at a contact portion of a separated component to smoothly perform operations such as locking and sliding. ..

To achieve the first and other objectives described above, the present invention provides a connector with an automatic locking structure configured to be connectable with a flat wire. The flat lead wire provides a leading end having the lead wire, and notches are formed on both sides of the leading end. The connector with an automatic lock structure includes a pedestal body, terminals, a lid body, and a lock fixing assembly member. The pedestal body has a first side wall and a second side wall. A storage space in which a flat lead wire can be installed is formed between the first side wall and the second side wall. A concave groove and a first locking member are formed on the first side wall and the second side wall, respectively. The recess is installed at the front edge of the first side wall and the front edge of the second side wall, and the first locking member is installed at the trailing edge of the first side wall and the trailing edge of the second side wall. The front edge is located at the outlet of the pedestal. The terminals are installed in the accommodation space. The terminal is electrically connectable to the lead wire. The lid has a shaft protrusion and a second locking member. The shaft protrusion is installed corresponding to the concave groove, and the second locking member is installed corresponding to the first locking member. The lock fixing assembly member is coupled to the lid. The lock fixing assembly member has an elastic arm and a lock fixing protrusion. The elastic arm is connected to the lock fixing protrusion. Among them, the shaft protrusion of the lid is coupled with the concave groove to generate an angle sandwiched between the lid and the pedestal. When the angle approaches 0 degrees, the first locking member and the second locking member are engaged with each other. After the flat lead wire enters the accommodation space through the insertion slot, the leading end acts on the lock fixing assembly member, causing the elastic arm to be deformed until the lock fixing protrusion is locked in the notch. After the elastic arm is repositioned, the locking projections can lock the flat conductor into the accommodation space. In addition, when the angle sandwiched between the lid and the pedestal is larger than the predetermined angle, the flat lead wire is retracted through the insertion port by releasing the locking between the first locking member and the second locking member.
