Abstract

PURPOSE:To shorten system length in a state where the insertion part of a connector main body is inserted in the connector receiving part of a light source device and coupled to it and to shorten and miniaturize the whole of an endo scope system by changing the direction of a coupling part between a connection cord to a different direction from the inserting direction of the insertion part by the direction changing part of the connector main body. CONSTITUTION:The direction changing part 40 changing the direction of the coupling part 30 of the connector main body 29 to the different direction from the inserting direction of a plug part 32 is formed of a coupling part between the plug receiving part 33 of the coupling part 30 and the coupling end part 36 of the plug part 32. After the light source connector of an endoscope is connected to the light source device, the coupling part 30 is rotated with respect to the plug part 32 and the light source connector is bent to be L-shaped as it is shown by a dotted line in a figure. Thus, the system length to a position where the connection cord is faced in a direction other than the inserting direction of the plug part 32 from the back end position of the light source device when the light source connector of the endoscope is connected to the light source device is shortened in comparison with a conventional way.

However, in the light source connector 2 of the conventional endoscope, since the connecting portion 3 of the connector body 2a with the connecting cord 1 on the endoscope side and the plug portion 6 are extended along a straight line, When the light source connector 2 of the endoscope is connected to the light source device 4, the connecting portion 3 is held in a state of being projected from the operation panel of the light source device 4 for a long time. Therefore, when the connection cord 1 is bent in a direction different from the insertion direction of the plug portion 6, the connection cord 1 is bent at a position relatively distant from the operation panel of the light source device 4 as shown in FIG. Therefore, the system length L from the position of the rear end 4a of the light source device 4 to the bent portion 1a of the connection cord 1 becomes long, which causes a problem in downsizing the entire system of the industrial endoscope.

Next, the operation of the above configuration will be described.
First, when the light source connector 26 of the endoscope 11 is connected to the light source device 13, the connecting portion 30 and the plug portion 32 of the connector body 29 have a basic shape in which they are straightly extended as shown by a solid line in FIG. Connect in the state. Then, the light source device 1
After the light source connector 26 of the endoscope 11 is connected to 3, the connecting portion 30 is rotated with respect to the plug portion 32 to bend the light source connector 26 into an L-shape as shown by a dotted line in FIG.

Therefore, in the above structure, the light source connector 26 can be bent in an L-shape, so that the light source device 26 when the light source connector 26 of the endoscope 11 is connected to the light source device 13 is connected. The system length L from the rear end position to the position where the connection cord 25 is directed in a direction other than the inserting direction of the plug portion 32 can be shortened as compared with the conventional system.
Therefore, it is advantageous for downsizing the entire endoscope system.

The light source device 13 and the light source connector 26 of the endoscope 11 are connected to the magnet 4 provided in the plug portion 32.
2 and the magnetic force of a magnet (not shown) provided on the light source device 13 side. Therefore, for example, when an abnormal external force is applied to the light source connector 26 such as when the connection cord 25 is hooked by a foot. The magnetic force can be adjusted by the screwing amount of the magnet 42 while the light source connector 26 is detached from the light source device 13. Therefore, it is possible to prevent damage to the light source connector 26 and improve durability.

Further, since the magnet 42 on the light source connector 26 side and the magnet on the light source device 13 side are both formed in substantially the same shape, only the magnet 42 on the light source connector 26 side and the magnet on the light source device 13 side stick to each other. The center axes of both magnets are aligned.
Therefore, a fitting portion for aligning the optical axis of the light guide 28 with the optical axis of the lamp 27 on the side of the light source device 13 is unnecessary, so that the light source connector 26 of the endoscope 11 and the connector receiving portion on the side of the light source device 13 are not required. The structure of the connecting portion can be simplified and the entire connecting portion can be miniaturized.

Further, the plug portion 32 of the connector body 29
Are brought closer to the magnet on the side of the light source device 13, and by the magnetic force of the magnet 42 on the side of the light source connector 26 and the magnetic force of the magnet on the side of the light source device 13, the light source connector 26 of the endoscope 11 and the connector receiving portion on the side of the light source device 13 are formed. The connecting part can be naturally attracted and connected. Therefore, when removing the light source connector 26 of the endoscope 11 from the connector receiving portion on the side of the light source device 13, it suffices to press the connecting portion 30 of the light source connector 26 from above. It is not necessary to hold the light source device 13 by hand. Therefore, the work of attaching / detaching the connector receiving portion on the side of the light source device 13 and the light source connector 26 of the endoscope 11 can be performed with one hand in the attaching / detaching work diagram, so that the workability of the attaching / detaching work can be improved. .
