Sliding to the bottom, the lower protrusion 413 of the second connector 400 is slid to the second connector lower slit 313 formed on the lower surface of the first connector 300, the front protrusion of the second connector housing 400 The 415 is inserted into the first connector recess 315 of the first connector 300 so that the second connector 400 is coupled to the first connector 300.

When the second connector 400 is inserted into the first connector 300, as shown in FIGS. 14 to 17, the connector pins 423 and the first connector pins 323 approach in a direction facing each other. Overlap and contact each other.

The pin contact extension portion 4237 of the connector pin 423 has a contact extension edge portion 4237a formed at both ends of the pin contact extension portion 3237 in contact with the first pin contact extension portion 3237 in the width direction both edges thereof.

The first pin contact extension part 3237 is bent toward the pin contact extension part 4237 and is bent in the opposite direction and is provided with a first pin protrusion part 337a protruding toward the pin contact extension part 4237. . An end portion of the first pin protrusion part 337a is provided with a first pin tilt extension part 337b extending from the first pin protrusion part 337a and inclined in a direction away from the pin contact extension part 4237. A first pin recess 3237d is concavely formed on a surface of the first pin protrusion 3237a facing the pin contact extension portion 4237.

When the first pin contact extension part 337 and the pin contact extension part 4237 approach and contact each other in a direction facing each other, the pin contact extension part 437 formed with the contact extension edge part 4237a has a first pin protrusion part. It is provided in sliding contact with the first pin concave portion 3237d which is a concave formed portion of the 3237a.

As shown in FIGS. 15 and 17, the pin contact extension portion 4237 is formed in a shape in which the vertical thickness s2 is larger than the width s1, and thus the deformation in the vertical direction ("B" in FIG. 14). Deformation in the width direction ("A" direction deformation in Figure 14) is easier than.

Since the first pin contact extension part 337 is formed by bending a portion of the end portion toward the connector pin 423 in the width direction, the width t1 is greater than the thickness t2 in the vertical direction, so that the width is wide. The deformation is easier in the vertical direction than the deformation in the direction.

Therefore, even when the plurality of first connector pins 323 arranged in alignment with the first connector housing 310 and the connector pins 423 arranged in alignment with the second connector housing 410 are in contact with each other, the connector is in contact with each other. Since the pin contact extension portion 4237 of the pin 423 is easily deformed in the width direction, and the first pin contact extension portion 337 can be easily deformed in the up and down direction, the up and down and width directions when engaging and separating. As it is deformed, it is automatically aligned so that it does not require a large external force.
