- the above-mentioned catch (34) is formed in a semicircular shape by protruding in the left and right directions perpendicular to the forward and backward direction of the optical fiber connector (100) from the stop of the aforementioned anchoring groove (31), so that an insertion surface (32) that is inclined diagonally is formed on the front side, and an anchoring protrusion (33) that is perpendicular to the anchoring groove (31) is formed on the rear side.
- the above stick portion (50) is formed with a fitting projection (53) that is fitted into the front opening (13) of the housing (10) described above at one end and fitted into the heart cam (40) at the other end, so that each time the plunger (30) is pressed, the fitting projection (53) moves clockwise along the recessed portion (41) of the heart cam (40) and is alternately fixed to the upper point (A) and the lower point (B) of the heart cam (40), thereby performing a repetitive operation, thereby fixing the rising and falling positions of the plunger (30).
- the stick part (50) for this purpose includes a horizontal stick (53), a vertical stick (52), and a fitting projection (53).
- the above horizontal stick (53) is fitted into the opening (13) and has a structure that allows it to rotate left and right on the bottom surface within the vertical installation space (11). However, since it can be removed to the outside when fitted horizontally, it is fitted so that it can be fitted diagonally within the vertical installation space (11).
- the above vertical stick (52) is extended upright from one end of the horizontal stick (53) toward the opening hole (12) so as to have an 'L'-shaped cross-section together with the horizontal stick (53).
- the above-described insertion projection (53) is a projection that corresponds to the heart cam (40) at the end of the above-described vertical stick (52) and is fitted so that it can move along the sunken portion (41) of the heart cam (40).
- the shape of the optical fiber connector (100) that is horizontally moved forward and backward while making corresponding contact with the upper surface of the plunger (30) described above in the present invention generally has a circular cross-sectional structure, and forms an insertion groove (130) formed on the outer periphery so that the engaging portion (34) of the plunger (30) described above corresponds and is inserted, and based on the insertion groove (130), the outer periphery diameter (second diameter (132)) of the rear end of the insertion groove (130) is made larger than the outer periphery diameter (first diameter (131)) of the front end, which becomes the insertion head portion.

- the closure (300) can be a target of various devices without being limited to types and fields, and it is natural that other devices can be used as a substitute for the closure.
- the optical fiber connector (100) When the optical fiber connector (100) is advanced while the aforementioned insertion projection (53) is positioned at the upper point (A) and the plunger (30) is pressed, the optical fiber connector (100) comes into contact with the upper surface of the plunger (30), and the first diameter (131) portion of the optical fiber connector (100) passes horizontally over the upper surface of the plunger (30), and then the second diameter (132) portion comes to the position of the plunger (30), and the plunger (30) is pressed as this second diameter (132) portion corresponds to the plunger (30).
- the insertion projection (53) is rotated in an inverted C ( ⁇ ) shape and moves to the lower point (B) located at the center of the lower side of the heart cam (40), and as a result, the plunger (30) is raised by the return force of the compressed elastic member (20), so that the engaging portion (34) is positioned higher than the upper surface of the housing (10).
- the optical fiber connector (100) when the optical fiber connector (100) is to be removed, the optical fiber connector (100) is advanced so that the second diameter (132) portion is positioned at the engaging portion (34), and the second diameter (132) portion presses the plunger (30) again, and as a result, the insertion projection (53) moves clockwise in a C shape and moves to the upper point (A) located at the center of the upper side of the heart cam (40), and as a result, the elastic member (20) is compressed again and the plunger (30) is lowered.
- the engaging portion (34) is positioned at the same horizontal line as the upper surface of the housing (10) or at a lower height, so that the optical fiber connector (100) can be completely detached from the upper surface of the plunger (30) by moving the optical fiber connector (100) backward so that it can be separated. (Case 2, when the optical fiber connector (100) is unmounted)
