Description

TECHNICAL FIELD [0001] The present invention relates to a universal-type optical cable holder and an optical cable connecting device including the optical connector. [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical cable holder for use in connection and maintenance of an optical cable and an optical cable connection apparatus including the optical cable holder. More particularly, the present invention relates to an optical cable connector for use with a single universal type holder, .

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.

FIG. 8 is a perspective view showing the rotation holding member of the optical cable holder shown in FIGS.

1 to 8, an optical cable connection apparatus according to an embodiment of the present invention includes a front surface 2001 and a back surface 2002, and connects the front surface 2001 and the back surface 2002 And an optical cable holder 1000 assembled to the assembly hole 2010 so as to protrude toward the rear surface 2002 and coupled to the panel 2000. The optical cable holder 1000 includes a holder housing 1100 having an optical fiber insertion hole into which the optical cables 1 and 1 'are inserted. The holder housing 1100 includes a base 1110 and a cover 1120 coupled to the base 1110. The holder 1100 includes optical cables 1 and 1 ' There are several built-in elements that make it universally available.

3 to 8, the optical cable holder 1000 includes a base 1110 having a virtual center of circle (c) as a part of the holder housing 1100. The base 1110 includes a circular inner guide portion 1112 protruding in a circular shape about the circular center c. The circular inner guide portion 1112 has three shaft holes 1113 formed at intervals of 120 degrees along a virtual circular path. The base 1110 includes an arc-shaped outer guide portion 1114.

The optical cable holder 1000 includes three rotation holding members 1200, 1200, and 1200 and one external force transmitting member 1300 that are positioned within the holder housing 1100. Although three rotary holding members 1200, 1200 and 1200 are used in this embodiment, it is also conceivable to use more than three rotary holding members 1200. [

Each of the rotation holding members 1200, 1200, and 1200 has a rotation axis 1210 in the middle of its length. The three rotation shafts 1210, 1210, and 1210 provided in the three rotation holding members 1200, 1200, and 1200 are spaced apart from the circular center c by a predetermined distance (C) of the circle center (c). Of course, the three rotation axes 1210, 1210, and 1210 are also arranged at intervals of 120 degrees.

Each of the three rotation shafts 1210, 1210 and 1210 is fitted to each of the three shaft holes 1113 to rotate the three rotation holding members 1200, 1200 and 1200 to the base 1110 .

Each of the rotation holding members 1200, 1200, and 1200 includes an inner end near the circular center c and an outer end far from the circular center c with respect to the rotation axis 1210 And an inclined surface 1220 having a predetermined angle is formed at the inner end.

When the rotary holding members 1200, 1200, and 1200 are rotated in one direction (clockwise direction) with respect to the rotation axis 1210, the shortest distance from the slope 1220 to the circular center c gradually increases. On the contrary, when the rotary holding members 1200, 1200, and 1200 are rotated in the opposite direction (counterclockwise) with respect to the rotation axis 1210, the shortest distance from the slope 1220 to the circular center c gradually increases .

The three rotation holding members 1200,1200 and 1200 are arranged such that each of the three slopes 1220 1220 and 1220 contacts the outer circumferential surface of the optical cable 1 or 1 ' '). Therefore, when the shortest distance between the inclined surfaces 1220, 1220, 1220 and the center of circle c is increased, the optical cable 1 having the relatively small diameter is held by the three inclined surfaces 1220, 1220, The two holding members 1200, 1200, and 1200 can hold the optical cable 1 'having a larger diameter by the same three inclined surfaces 1220, 1220, and 1220.

Each of the three rotation holding members 1200, 1200 and 1200 has the operation protrusions 1230, 1230 and 1230 near the outer end far from the circle center c as described above, The external force transmitting member 1300 transmits an external force to the three rotation holding members 1200, 1200 and 1200 through the operation protrusions 1230, 1230 and 1230 to rotate the three rotation holding members 1200, 1200, and 1200 are simultaneously rotated.

The external force transmitting member 1300 integrally includes a rotation lever 1310 extending to the outside of the holder housing 1100 through a lever guide hole formed in the holder housing 1100. For example, (Clockwise direction) with respect to the circular center c by an external force that is held by the rotation holding members 1200, 1200, and 1200 simultaneously. The rotation holding members 1200 can simultaneously rotate in the same direction (clockwise direction) by the unidirectional rotation of the external force transmitting member 1300. At this time, the circle center c and the slope 1220 can be rotated, Is gradually increased to enable the use of the optical cable 1 'of a larger diameter.

The optical cable holder 1000 may further comprise an elastic biasing force for rotating the external force transmitting member 1300 in the opposite direction (counterclockwise direction) when the external force applied to the external force transmitting member 1300 is removed, 1300). ≪ / RTI >

While the external force transmitting member 1300 is rotated in the counterclockwise direction, the rotation holding members 1200 are rotated in the counter-clockwise direction by elastic restoring rotation, and the external force is transmitted between the circular center c and the inclined surfaces 1220, 1220, Is shortened.

As described above, if the external force to the external force transmitting member 1300 is removed after the external force is applied to the external force transmitting member 1300 to secure an inner diameter capable of inserting the optical cable 1 or 1 'having a specific diameter, The external force transmitting member 1300 is rotated in the opposite direction by the resilient restoring force of the elastic member 1400 so that the rotational holding member 1300 is rotated in the direction of reducing the shortest distance between the circular center c and the slope 1220 . Thus, the inclined surfaces 1220 of the rotation holding member 1200 strongly hold the optical cable 1 or 1 '.

At this time, since the biasing force of the elastic member 1400 for rotating the external force transmitting member 1300 in the counterclockwise direction continues to operate, the optical cables 1, 1 ' And can be maintained reliably.

1 and 2, the elastic member 1400 is located outside the holder housing 1100, and the external force transmitting member 1300 is fixed to the holder housing 1400 so as to be connected to the elastic member 1400. [ And a connection arm 1360 extending outwardly from the base plate 1100. The elastic member 1400 may be a tension coil spring having one end connected to the connection arm 1360 and the other end connected to a bracket 2500 provided on the panel 2000.

3 to 7, the external force transmitting member 1300 has an inner circumferential surface rotatably slidably contacted with a circular inner guide portion 1112 of the base 1110, and an outer circumferential surface of the outer force transmitting member 1300 has an arc- (The outer guide portion 1114) so as to be rotatably slidable, so that the rotation movement is guided around the center c of the base 1110.

The external force transmitting member 1300 includes operating grooves 1330, 1330, and 1330 for accommodating the operating protrusions 1230 of the rotary holding members 1200 at intervals of 120 degrees on the inner circumferential surface. The operating grooves 1330, 1330 and 1330 are formed on the inner working surface 1332 for rotating the rotation holding members 1200 and 1200 by pressing the operating protrusions 1230 when the external force transmitting member 1300 rotates. ). A portion of the rotation section of the external force transmitting member 1320 exists in a section in which the internal working surface 1332 and the operation protrusion 1230 do not operate.
