a holding part that composes a bottom part and a side wall part wherein the adhesive layer sits on the bottom part, and the side wall part extends perpendicular to the bottom part to hold the adhesive layer while exposing at least the exposed surface, the cleaning method, comprising:
pressing the connector into the adhesive layer until the exposed surface of the adhesive layer reaches the end surface of the connector in a manner that the axial direction of the guide pin is oriented perpendicular to the bottom part, a leading tip of the guide pin comes into contact with the exposed surface of the adhesive layer at a contact position and the exposed surface is deformed as the guide pin projects towards the bottom part such that the exposed surface wraps the guide pin, and next
pulling the connector out of the adhesive layer, wherein
a distance measured from a center of the contact position to the side wall part, which is defined in a direction perpendicular to the axial direction of the guide pin, is greater than the pin length of the guide pin,
the adhesive layer is in a cuboid shape, having a length in a length direction (LD), a width in a width direction (WD) and a height in a height direction (HD), each of the length, width and height directions being perpendicular to the other two directions,
the adhesive layer has a first adhesive side surface and a second adhesive side surface that are perpendicular to the exposed surface, facing each other either in the width direction or in the length direction,
the side wall part has a first side wall part and a second side wall part facing each other,
in the holding part, the first adhesive side surface and the first side wall part face each other, the second adhesive side surface and the second side wall part face each other wherein the adhesive layer intervenes between the first side wall part and the second side wall part such that the first and second side wall parts hold the adhesive layer,
the holding part has a recessed portion that is surrounded with the first and second side wall parts and the bottom part, into which the adhesive layer is contained,
the recessed portion has a depth in the height direction and either the depth of the recessed portion or the height of the adhesive layer is greater than the pin length of the guide pin,
each of the first and second side wall parts has a tip portion facing toward the end surface of the connector, and
the exposed surface of the adhesive layer is protruded beyond the tip portions while the adhesive layer is contained in the recessed portion.
2. A cleaner comprising:
an adhesive layer having an exposed surface facing an end surface of a connector from which a guide pin protrudes in an axial direction wherein the guide pin has a predetermined pin length (GL) in the axial direction, the adhesive layer being elastically deformable when subjected to contact with the guide pin; and
a holding part that composes a bottom part and a side wall part for holding the adhesive layer while exposing at least the exposed surface, wherein
when the connector is pressed into the adhesive layer toward the bottom part, a leading tip of the guide pin comes into contact with the adhesive layer at a contact position, deforming the exposed surface as the guide pin projects towards the bottom part such that the exposed surface wraps the guide pin, and
a distance measured from the contact position to the side wall part, which is defined in a direction perpendicular to the axial direction of the guide pin, is greater than the pin length of the guide pin,
the adhesive layer is in a cuboid shape, having a length in a length direction (LD), a width in a width direction (WD) and a height in a height direction (HD), each of the length, width and height directions being perpendicular to the other two directions,
the side wall part has a first side wall part and a second side wall part that are arranged in parallel to face each other at both ends of the holding part in the width direction such that the adhesive layer, which is accommodated in the holding part, is sandwiched between the first side wall part and the second side wall part in the width direction,
the holding part has no side wall at both ends in the length direction such that the adhesive layer is not hold in the length direction,
the height of the adhesive layer is greater than the pin length of the guide pin, and
the length of the adhesive layer is greater than a length of the holding part, which is measured in the length direction, such that the adhesive layer is protruded from the holding part in the length direction.
