Abstract
Description
BACKGROUND OF THE
In general, an endoscope apparatus requires a light source for illuminating the inside of a dark object, in order to observe a dark object (in particular, a human body). The optical cable serves as a light guide for transmitting the light generated from the light source to the inside of the object. For example, in the case of an apparatus or system for transmitting light using an optical cable, such as an endoscope apparatus, an optical cable connecting apparatus for connecting and holding the optical cable is employed. The optical cable connection device includes an optical cable holder for holding the inserted optical cable. Conventional optical cable connecting apparatuses include optical cable holders capable of holding only a single-diameter optical cable, so that the use of optical cables of various diameters has been limited. For this reason, the conventional optical cable connecting apparatuses use various types of optical cable holders corresponding to optical cables of various diameters by dialing. However, the prior art has a limitation in using optical cables of various diameters because the number of parts is large and the optical cable standard that can be used corresponds to the number of holders is also limited.
SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a universal type optical cable holder capable of using optical cables having various diameters, and an optical cable connecting apparatus including the same.
A universal type optical cable holder according to one aspect of the present invention includes: a holder housing having a circle center; At least three rotation holding members positioned in the holder housing and rotating about rotational shafts spaced a certain distance from the center of the circle; And an external force transmitting member rotating in one direction with respect to the center of the circle by an external force to simultaneously rotate the rotation holding members, wherein the rotation holding members include an inclined surface at an inner end near the center of the circle with respect to the rotation axes And the shortest distance between the circle center and the inclined surface gradually increases while the rotary holding members are rotated by the unidirectional rotation of the external force transmitting member.
According to one embodiment, the universal type optical cable holder further includes an elastic member for providing an elastic biasing force to the external force transmitting member for rotating the external force transmitting member in the opposite direction when an external force applied to the external force transmitting member is removed , The shortest distance between the circle center and the inclined surface gradually decreases while the rotary holding members are rotated in the reverse direction by the opposite rotation of the external force transmitting member.
According to one embodiment, the rotation holding members include operating protrusions, and the external force transmitting member has operating grooves on the inner circumferential surface side thereof at regular intervals on the inner circumferential surface to receive the operating protrusions, And an inner working surface for pressing the operating projections to rotate the rotating holding members when rotating.
According to one embodiment, the external force transmitting member further includes a rotation lever extended to the outside of the holder housing to receive an external force, and the holder housing includes a lever guide hole for guiding the rotation lever to rotate at a predetermined angle, Respectively.
According to one embodiment, the elastic member is located outside the holder housing, and the external force transmitting member includes a connection arm extending outside the holder housing to be connected to the elastic member.
According to one embodiment, the holder housing includes a base, the base including: a circular inner guide portion protruding to be slidably in contact with an inner peripheral surface of the external force transmitting member; And the inner guide portion includes shaft holes in which the rotation shafts are installed along one circular path.
According to another aspect of the present invention, an optical cable connecting apparatus includes an optical cable holder and a panel to which the optical cable holder is coupled.
The optical cable connecting apparatus according to the present invention uses a plurality of holding members that are simultaneously rotated by an external force transmitting member, unlike the prior art in which an optical cable holder capable of holding only a single-diameter optical cable is used or a dial- , And has the advantage of easily and reliably holding optical cables of various diameters.
