By acting on the second snap member 166, the first snap member 1214 causes the upper shell 12 to limit the rubber core 16 in the first accommodation space FSP. See Figure 9 for both. It is a side view which shows the easy lock connector which provided the press lock release structure of this invention.

See also Figure 5. It is a figure which shows the structure of the lower shell of FIG. 1 of this invention. In FIG. 5, the lower shell 14 is installed in the first accommodation space FSP. The lower shell 14 forms one second accommodation space SSP having one elastic member 142, one stopper member 144, one extension arm 146 and one lower body 148.

When an external force is applied to the press member 124 of the upper shell 12, even if the press member 124 is attached to the inclined surface 168, the press member 124 is recessed until the press member 124 completely contacts the inclined surface 168 and stops. It sinks into the ditch. By limiting the movement of the press member 124 by the inclined surface 168, the press depth of the press member 124 can be determined.

Therefore, when the flat wire 2 is introduced into the insertion port 162, the gap 22 comes into contact with the stopper member 144, which changes the shapes of the extension arm 146 and the elastic member 142, and finally the stopper 144 is combined with the gap 22. .. After the gap 22 of the flat wire 2 is combined with the stopper 144 member, by pushing the press member 124, the press member 124 applies an external force to the elastic member 142, the elastic member 142 is deformed, and the amount of shape change of the elastic member 142 is further increased. Is related to the tilt ratio of the tilted surface 168, so that the elastic member 142 interlocks with the extension arm 146 to actuate the stopper member 144 in one direction, releasing the state in which the stopper member 144 is engaged with the gap 22. , Thereby achieving the unlocking purpose.

See FIG. It is a structural drawing of the easy lock connector provided with the press lock release structure according to the 2nd Example of this invention. In FIG. 10, the easy lock connector 10'with the press lock release structure includes not only the upper shell 12, the lower shell 14, the rubber core 16 and the terminal 18 of the first embodiment, but also the iron shell shield 20. ..

The description of the upper shell 12, the lower shell 14, the rubber core 16 and the terminal 18 is as described above, and will not be described again.

The iron shell shield 20 is installed in the upper shell 12, and its structure is depicted in FIG. FIG. 11 is an exploded view of FIG. 10 of the present invention. In FIG. 11, the iron shell shield 20 further includes a first outer clip member 202, a first iron shell grounding 204, and a plug 206. The first outer clip member 202 is formed on both sides of the iron shell shield 20, and the first iron shell grounding 204 and the plug 206 are installed at the insertion port 162 near the rubber core 16. The ferrous shell ground 204 is a ground wire that can come into contact with the flat wire 2.

Further, the upper shell 12 further includes a second outer grip 1216, and the rubber core 16 further includes a socket 1610 and a ground opening 1612. The second outer grip 1216 is installed corresponding to the first outer grip 202. The socket 1610 is installed corresponding to the plug 206, and the grounding opening 1612 is installed corresponding to the ferrous shell grounding 204. With the plug 206, the first outer grip 202, the second outer grip 1216 and the socket 1610, the iron shell shield 20 covers the upper shell 12 and the rubber core 16.

See also FIG. It is a figure which shows the connection of the easy lock connector provided with the press lock release structure of this invention, and a circuit board. In addition to the upper shell 12, the lower shell 14, the rubber core 16, the terminals 18, and the iron shell shield 20 in FIG. 12, the iron shell shield 20 further includes a second shell grounding 208 and a third shell grounding 2010.

Of particular note is that the structure of the plug 206, the first outer grip 202, the second outer grip 1216 and the socket 1610 described above creates, for example, a vertical floating effect, that is, the first outer grip 202 and the second. Due to the design of the outer grip 1216, for example, if the first outer grip 202 is an opening and the second outer grip 1216 is a convex piece, the convex piece may move within the opening when the opening is larger than the convex piece. Since the positions of the second shell grounding 208 and the third shell grounding 2010 of the iron shell shield 20 can be adjusted on the surface of the circuit board 4, they can be smoothly welded to the circuit board 4.
