Abstract

A connector provided with a self-locking structure is provided. The present invention includes a pedestal, a terminal, a lid, and a locking assembly member. The lid provides an axial protrusion that engages with the concave groove of the pedestal, thereby generating an angle between the lid and the pedestal. When the angle approaches 0 degree, the first locking member of the pedestal and the second locking member of the lid are engaged with each other, and the lid is fixed to the pedestal to form a receiving space. After the flat conductor enters the receiving space, the leading end of the flat conductor acts on the locking fixing assembly member to lock the flat conductor in the receiving space. When the angle clamped by the lid and the pedestal is larger than a predetermined angle, the first locking member and the second locking member are released to evacuate the flat conducting wire from the accommodation space.

Connector with self-locking structure {CONNECTOR WITH AN AUTOMATIC LOCK STRUCTURE}

The present invention relates to the technical field of a connector, and more particularly, to a connector provided with a self-locking structure for latch locking a flat conductor.

A traditional wire-to-board connector is configured as a connecting element for electrically connecting a conductor wire and a circuit board, and its advantage is that it does not need to be soldered onto the circuit board by using a practical solder connection method, and the user can By simply inserting (plugging in) and removing it, the effect of electrical connection can be realized.

In order to make a connector and a conducting wire contact stably, many types of connection methods have been developed so far, for example, the automatic latching method which can connect a connector and a conducting wire simply and can prevent it from falling off is mentioned. In this method, it is possible to automatically lock the latch in the process of inserting the conductor into the connector as in the above operation, and maintain the connection between the connector and the conductor. Since the locking structure is complicated and the thickness is increased, it is not suitable for thinning applications.

Here, the front edge and the back edge indicate that they have a corresponding relationship with each other, and the front edge indicates one end into which the flat conductor 2 is inserted, that is, the front edge is located in the insertion hole 126 of the pedestal 12 . has been

The thickness of the concave groove 128 portion of the first sidewall 122 is greater than or equal to the thickness of the remaining portion of the first sidewall 122 . Here, a case in which the thickness of the concave groove 128 portion in the first side wall 122 is larger than the thickness of the remaining portion in the first side wall 122 will be described as an example, which is mainly the strength of the concave groove 128 . can be made stronger, and by being provided in conformity with the shaft projection 162 to be described later, the lid 16 can be rotated, and there is no simple insulation. Similarly, the structure of the second sidewall 124 may be symmetrically disposed on the first sidewall 122 .

In addition, the first side wall 122 and the second side wall 124 may form a chamfer angle also at the edge portion, and serve the purpose of smooth positioning or mounting when in contact with other parts. can do.

The terminal 14 is provided in the accommodation space SP, and the terminal 14 is electrically connectable with the conducting wire 6 .

In addition, here, by making the width of the concave groove 128 in the first side wall 122 larger than the width of the first locking member 1210 portion, a structure in which the diameter is gradually reduced, later It is possible to smoothly slide in the mentioned lid 16 . Similarly, the width of the concave groove 128 of the second side wall 124 is also larger than the width of the first locking member 1210 portion.

4A and 4B are also referred to. 4A is a front view illustrating the lid of FIG. 1 of the present invention, and FIG. 4B is a rear view illustrating the lid of FIG. 1 of the present invention. The lid 16 has a shaft protrusion 162 and a second locking member 164 . The shaft protrusion 162 is installed to correspond to the concave groove 128 , and the second locking member 164 is installed to correspond to the first locking member 1210 .

It should be noted that, here, the shaft protrusion 162 includes a plurality of slopes for inserting into the recessed groove 128 and pivoting in the recessed groove 128, and the operator uses the other slopes to insert the current lid 16. It is possible to know in detail the purpose of the rotation state or position restriction of 7, which is a coupling schematic diagram illustrating the coupling between the shaft protrusion of the lid of FIG. 1 and the concave groove of the pedestal of the present invention, may be referred to together.

In addition, in the portion where the first locking member 1210 and the second locking member 164 are in contact with each other, a chamfer angle is formed on the first locking member 1210, the second locking member 164, or both. Therefore, it achieves the purpose of smoothly performing positioning or mounting.

In addition, since the lid 16 is further formed with an opening 166 for accommodating the lock assembly member 18 to be mentioned later, the amount of deformation caused by the lock assembly member 18 can be eliminated, and the lid 16 . It is also possible to eliminate concerns about the effect of deformation.

5A and 5B are referred to together. FIG. 5A is a top view illustrating the lock assembly member of FIG. 1 of the present invention, and FIG. 5B is a schematic cross-sectional view illustrating the coupling between the lock assembly member of FIG. 1 and the flat conductor of the present invention. A locking assembly member (18) is coupled to the lid (16). 5A and 5B , the locking assembly member 18 has an elastic arm 182 and a locking projection 184 . The elastic arm 182 is connected to the locking protrusion 184 . Among them, the shaft protrusion 162 of the lid 16 is coupled to the concave groove 128 , so that the angle θ is pinched by the lid 16 and the pedestal 12 .

In one embodiment, first, the elastic arm 182 is surrounded by the lid 16 by mold molding in which the distal end of the elastic arm 182 fits into a colloid (ie, referred to herein as the lid 16 ).

Further, since the shape of the edge of the locking protrusion 184 may be an arc-shaped curve, the leading end 8 of the flat conductor 2 is simply pushed open by the locking protrusion 184 to open the receiving space SP ), and the cut-out 4 is also regulated by the locking fixing protrusion 184 having an arc-shaped curve, and the position is limited in the receiving space SP.

Due to this, after the flat conductor 2 enters the accommodation space SP through the insertion hole 126, the leading end 8 acts on the lock assembly member 18, so that the locking projection 184 is cut out (4). ), the elastic arm 182 is deformed until it is caught, and after the elastic arm 182 is returned to its position, the locking protrusion 184 can lock the flat conductor 2 to the receiving space SP. . Conversely, when the angle θ clamped by the lid 16 and the pedestal 12 is greater than a predetermined angle, by releasing the engagement between the first locking member 1210 and the second locking member 164, the insertion hole 126 ) through which the flat conductor 2 can be evacuated.

It should be noted that the range of the above-described angle θ may be, for example, between 0 degrees and 90 degrees, and the above-described predetermined angle range may be, for example, between 3 degrees and 90 degrees.
