Description

Connector receiver, connector connection system, light source device, endoscope

The present invention relates to a connector receiver to which a connector can be connected, a connector connection system, a light source device, and an endoscope.

In recent years, endoscopes are widely used in the medical field and the industrial field. An endoscope used in the medical field observes an organ in a body cavity by inserting an elongated insertion portion into a body cavity, or inserts into an insertion channel of a treatment instrument provided in the endoscope as necessary. Various treatments can be performed using the treatment tool.

Here, in an endoscope having a configuration in which light supplied from a light source device is irradiated into a body cavity using a light guide provided in the endoscope, the endoscope provided at the extended end of the universal cord In a mirror connector, by connecting the endoscope connector to a connector receiver provided in the light source device, an elongated ride guide connector (hereinafter referred to as LG connector) provided in the endoscope connector, an air supply connector, etc. Is inserted into a hole formed in the connector receiver, and after the connection, the electrical connector provided on the endoscope connector is connected to a known video processor for controlling the operation of the endoscope via a connection cable. The configuration of being electrically connected and used is well known.

However, in this configuration, when using the endoscope, the operator connects the endoscope connector to the connector receiver of the light source device and inserts and connects the LG connector, the air supply connector, and the like. Thus, two operations, that is, an operation of electrically connecting the electrical connector via the connection cable are required, and the connection operation is very complicated for the operator.

In view of such circumstances, Japanese Patent Application Laid-Open No. 2002-34912 discloses that the first electrical contact of the electrical connector provided in the endoscope connector is connected to the connector receiver of the light source device to which the endoscope connector is connected. A configuration in which a second electrical contact to be electrically connected is disclosed, and a connector connection system including a connector receiver of the light source device and an endoscope connector connected to the connector receiver Is disclosed.

In the light source device disclosed in Japanese Patent Laid-Open No. 2002-34912, the light source device and the video processor are electrically connected separately by a connection cable.

According to such a configuration of the connector connection system, when the endoscope connector is connected to the connector receiver of the light source device by the operator, not only the LG connector is inserted into the hole of the connector receiver but connected, the first And the second electrical contact are electrically connected, and the electrical connector is electrically connected to the video processor via a connection cable. From this, the operator performs the work of inserting an LG connector or the like into the hole of the connector receiver of the light source device and connecting it in one operation, and the operation of electrically connecting the electric connector to the video processor. It can be carried out.
By the way, the LG connector is generally provided so as to extend from the end surface in the extending direction of the housing portion of the endoscope connector so as to be separated along the extending direction. Therefore, after the LG connector is inserted into the hole, light is supplied to the LG connector from the light source close to the extension end in the light source device with respect to the extension end of the LG connector.

Here, due to the assembly error when manufacturing the endoscope connector and the dimensional error of each component constituting the endoscope connector, the LG connector is not viewed from the end surface of the casing portion of the endoscope connector. In some cases, the mirror connector is assembled with an eccentricity relative to the radial direction of the mirror connector.

This is because the diameter of the LG connector, the diameter of the endoscope connector, and the amount of extension of the LG connector from the end face of the casing can be set strictly, but from the outer peripheral edge of the endoscope connector. The radial distance to the LG connector is due to a design reason that dimensional variation is inevitably generated.

Thus, when the LG connector is eccentrically positioned in the radial direction, when the LG connector is inserted into the hole of the connector receiver, the LG connector is inclined and inserted into the hole. From this, after the insertion, the LG connector is not properly connected and rattles, and the amount of light supplied from the light source to the end face of the LG connector may be lower than the set amount of light. As disclosed in Patent Document 1, as the LG connector is inserted, the first electrical contact provided on the endoscope connector is electrically connected to the second electrical contact of the connector receiver. There has been a problem that the connection between the contacts may be uncertain.

Further, an LG socket 33 made of, for example, resin is fixed to the receptacle folder 24 at the distal end side of the outer receptacle 21, the inner receptacle 22, and the receptacle folder 24.

The LG socket 33 is formed with a hole 33h penetrating from the distal end side to the proximal end side of the protruding portion 33t along the insertion direction K.

The hole 33h is for receiving the LG connector 10 when the endoscope connector 5 is connected to the connector receiver 20. Further, as described above, the LG connector 10 is formed so that the diameter of the LG connector 10 decreases as it goes rearward in the insertion direction K because the step portion 10d is formed in the middle position in the insertion direction. Therefore, when the LG connector 10 is inserted into the hole 33h, a second gap B is generated between the outer peripheral surface of the LG connector 10 and the LG socket 33 as shown in FIG.

Although not shown, the second gap B is formed so that the width in the radial direction R increases toward the rear, and the LG connector 10 is fitted in the hole 33h, and the receptacle 33 is inserted into the receptacle 33. The inserted first insertion portion 15 a and second insertion portion 15 b are formed in the receptacle folder 34 so as not to be extremely inclined together with the receptacle 33.

The second gap B is formed so that the LG connector 10 has a constant diameter along the insertion direction K, and the hole 33h is formed so that the hole diameter increases, for example, by a taper or a stepped portion as it goes rearward. Therefore, when the LG connector 10 is inserted into the hole 33h, the structure may be formed between the outer peripheral surface of the LG connector 10 and the LG socket 33.

Further, in the LG socket 33, a circumferential groove 33m desired for the hole 33h is formed in the middle of the insertion direction K in the hole 33h, and a ring member 95 made of, for example, metal is inserted into the groove 33m. ing.

In the ring member 95, the C-ring 210c for fixing the endoscope connector is fixed to the connector receiver 20 at a midway position in the fitting direction K of the LG connector 210 extending forward from the housing 215 as shown in FIG. When the LG connector 210 is inserted into the hole 33h when the endoscope connector 205 is connected, the C-ring 210c expanded outward in the radial direction R is brought into contact with the C-ring 210c by collapsing in the radial direction R. As a result, the position of the endoscope connector 205 is fixed. The C-ring 210c is used for fixing the endoscope connector 205 to the connector receiver having the conventional structure by being crushed and expanded in the hole into which the LG connector is inserted in the connector receiver having the conventional structure. It is what

As shown in FIG. 11, the tapered surface 95 t is formed on the base end side of the ring member 95, so that the C ring 210 c is easily inserted into the ring member 95.

Further, as described above, in the present embodiment, the hole 33h is directed rearward so that the second gap B is generated between the outer peripheral surface of the LG connector 10 and the inner peripheral surface of the hole 33h of the LG socket 33. Therefore, the second gap B may prevent the C ring 210c provided in the midway position in the insertion direction K of the LG connector 10 from being crushed by the hole 33h. However, by providing the ring member 95, the ring member 95 can reliably crush the C-ring 210c.

Further, since the ring member 95 is inserted into the groove 33m so as to be movable in the front and rear in the radial direction R and the insertion direction K, temporarily, in the radial direction R on the front end surface of the housing portion 215. Even if the LG connector 210 located eccentrically is inserted into the hole 33h or the LG connector 210 is inserted obliquely with respect to the hole 33h, the ring member 95 can be reliably Since the ring 210c can be crushed, the position of the LG connector 210 to which the distal end side is fixed can be reliably fixed by the positioning ring 34 described later.

Furthermore, when the C-ring 210c passes through the ring member 95, a click feeling is generated, so that it is possible to prevent half insertion of the connector receiver 20 by the operator.

Thus, the ring member 95 has a function of fixing the position of the endoscope connector 205 to which the distal end of the LG connector 210 is fixed by a positioning ring 34 described later.

As described above, the ring member 95 allows the connector receiver 20 of the present embodiment to connect the endoscope connector 205 in which the C ring 210c is fixed at a midway position in the fitting direction K of the conventional LG connector 210. It is configured.

Here, as described above, when the endoscope connector 5 is connected to the connector receiver 20, the receptacle 23 is located in the first gap A with respect to the receptacle folder 24, and the outer contact 7 The receptacle 23 is held so as to be independently movable before and after the radial direction R and the insertion direction K in a state where it is electrically connected to the outer contact 25 and the inner contact 8 is electrically connected to the inner contact 26. I showed. However, if the harness electrically connected to the

electrical contacts

25 and 26 is pulled out in one direction with respect to the substrate 27 fixed to the receptacle 23, the receptacle 23 is pulled out in the receptacle folder 24 in the direction in which the harness is pulled out. There is a problem that it is inclined to the position.

Therefore, in the present embodiment, as shown in FIG. 12, a plurality of connection connectors 49 for the

electrical contacts

25 and 26 are provided on the substrate 27, and each connector 49 and a predetermined connector in the light source device are provided from each connector 49. The harness 44 for electrically connecting the electrical circuit is configured to be pulled out in a plurality of directions.

Thereby, the force applied from the harness 44 to the substrate 27 is dispersed, so that the receptacle 23 can be positioned in the receptacle folder 24 in a good posture.

4 and 6, the positioning ring 34, which is a light guide connector engaging member for fixing the distal end side of the LG connector 10 inserted in the hole 33 h, is attached to the LG socket 33 on the distal end side of the LG socket 33. It is fixed.

It should be noted that the hole diameter of the hole 34h of the positioning ring 34 is formed to be approximately the same as the diameter 10r on the distal end side of the LG connector 10. From this, the positioning ring 34 can fix the front end side of the LG connector 10 inserted into the hole 34h.

The heat sink 35 is fixed to the positioning ring 34 and is provided so as to cover the front end of the LG connector 10. The heat sink 35 is a member that prevents the tip of the LG connector 10 from being heated when light is supplied from the light source in the light source device 50 to the tip of the LG connector 10.

Thus, in the present embodiment, the connector receiver 20 uses the positioning ring 34 that fixes the distal end side of the LG connector 10 fitted in the hole 33 h of the LG socket 33 to the distal end side of the LG socket 33. Shown to be fixed.

Further, when the endoscope connector 5 is connected to the connector receiver 20 and the LG connector 10 is inserted into the hole 33h, there is a gap between the outer peripheral surface of the LG connector 10 and the inner peripheral surface of the hole 33h of the LG socket 33. The hole 33h is formed to have a larger diameter toward the rear so that the second gap B is formed, or the LG connector 10 is formed to have a smaller diameter toward the rear.

Further, when the endoscope connector 5 is connected to the connector holder 20, the receptacle folder 24 is electrically connected to the receptacle folder 24 in the first gap A and the outer contact 7 is electrically connected to the outer contact 25. In the state where the inner contact 8 is electrically connected to the inner contact 26, the receptacle 23 is shown to be held so as to be movable independently in the radial direction R and the insertion direction K. .

According to this, the LG connector 10 produces an assembly error when manufacturing the endoscope connector 5 with respect to the distal end surface 15bf of the second insertion portion 15b, and the components constituting the endoscope connector 5 are not affected. Even if the endoscope connector 5 is connected to the connector receiver 20 due to a dimensional error, if the LG connector 10 eccentric to the hole 33h is inserted, the LG connector 10 is inserted. The tip position of the connector 10 is fixed by the positioning ring 34.

Therefore, the LG connector 10 is movable in the radial direction R by the second gap B while the distal end side is fixed by the positioning ring 34, and the receptacle 23 is in the hole 33h. The outer contact 7 and the outer contact 25 are electrically connected in the receptacle folder 24 in the radial direction R and the insertion direction K before and after the LG connector 10 that is eccentric to the center. Since the inner contact 8 and the inner contact 26 are movable while being electrically connected, the connection between the electrical contacts does not become uncertain.

Note that the receptacle 23 can be moved without releasing the connection between the electrical contacts because the endoscope inserted into the receptacle 23 when the endoscope connector 5 is connected to the connector receiver 20. This is because the position of the endoscope connector 5 in the rotational direction with respect to the receptacle 23 is defined by the key portion 6 because the key portion 6 of the connector 5 is fitted in the key groove 21 m of the outer receptacle 21.

That is, even if the endoscope connector 5 is connected to the connector receiver 20 from an oblique direction due to the above-described error, the electrical connection between the outer contact 7 and the outer contact 25 and the inner contact 8 and the inner contact 26 There will be no uncertain electrical connection.

Further, since the distal end side of the LG connector 10 is securely fixed and positioned by the positioning ring 34, it is assumed that the endoscope connector 5 is connected to the connector receiver 20 from an oblique direction due to the above-described error. In addition, a sufficient amount of light can be supplied from the light source of the light source device 50 to the tip of the LG connector 10.

The above is not limited to the case where the LG connector 10 is eccentric with respect to the distal end surface 15bf of the second insertion portion 15b, and the LG connector 10 is inclined and inserted into the hole 33h of the connector receiver 20. Even if it has been done, it is the same.

From the above, a connector receiver in which the LG connector and the electrical contacts of the electrical connector are connected at once, and the connector receiver has a configuration that allows the LG connector to be fitted without play even if the LG connector is eccentric. 20. A connector connection system 100 can be provided.

In the present embodiment, the connector receiver is described by taking the connector receiver of the light source device to which the endoscope connector provided at the extended end of the universal cord of the endoscope is connected as an example. The connection system has been described by taking a connector connection system including an endoscope connector and a connector receiver of a light source device as an example. However, the connection system is not limited to this, and a connector other than an endoscope, for example, a treatment instrument has a connector. Needless to say, the present invention can also be applied to a connector receiver to which a connector is connected, and a connection system using the connector receiver and a connector provided in a device other than an endoscope.
