TECHNICAL FIELD OF THE INVENTION
The present invention relates to a medical device such as an endoscope device, and more particularly to an improvement in a connector mounting structure.
[0002]
[Prior art]
2. Description of the Related Art A housing (equipment main body) that constitutes a light source of an endoscope apparatus, which is a medical equipment, has panels on upper and lower surfaces, front and rear surfaces, and left and right side surfaces. Various electric components are attached to the panel on a predetermined surface.
[0003]
FIG. 4A is a perspective view of a housing K constituting a light source unit of the endoscope apparatus, as viewed from a rear surface side.
A power supply connector c to which a power cord b is electrically connected, a video input / output connector d to be connected to a television monitor (not shown), and peripheral devices are provided at predetermined positions on a rear panel a of the housing K. A communication connector e is provided.
[0004]
Regardless of the light source unit of the endoscope apparatus, the housing K of a general medical device includes not only the left and right side panels f, but also the front panel g and the rear panel a to which the power connector c is attached. It is perpendicular to the installation surface on which K is installed.
[0005]
In such a medical device, depending on the use environment, a water drop or a chemical solution (hereinafter, referred to as a liquid) may fall on the housing K. In many cases, workers are extremely busy at medical sites, and there is no room for immediately wiping and removing the liquid even when it falls on the housing K, and it is usually performed after all necessary work is completed. .
Therefore, it is conceivable that the liquid that has fallen on the casing K may wet the electrical components attached to these panel surfaces while flowing down the panel surfaces.
[0006]
FIG. 4B is an enlarged cross-sectional view showing a mounting portion of the power connector c in the housing K of the endoscope apparatus.
The power connector c has a recess j attached to the rear panel a of the housing K and having an electrical contact i, and an electrical contact including a not-shown hole provided at the tip of the power cord b and inserted into the electrical contact i of the recess j. And a connector section m provided with
[0007]
Since the connector portion m is removably inserted into the electric contact i of the concave portion j, the connector portion is so arranged that a slight gap exists between the inner peripheral surface of the concave portion j and the outer peripheral surface of the connector portion m. The outer shape of m and the inside of the concave portion j are formed.
[0008]
When the liquid n falling on the rear panel a is left as it is, the liquid flows down along the rear panel a and finally reaches the power supply connector c. Alternatively, the splashed liquid may directly scatter to the power supply connector c.
[0009]
In any case, the liquid n penetrates into the gap between the inner peripheral surface of the concave portion j and the outer peripheral surface of the connector m due to the capillary phenomenon. The smaller the gap is, the easier the infiltrated liquid stays as it is, and if the liquid subsequently enters, the gap is filled.
[0010]
On the other hand, since the electrical contact i needs to be electrically connected to the connector m, it cannot be insulated. Therefore, the electrical contacts i are electrically connected to each other by the filled liquid n, and a so-called leakage state occurs.
[0011]
An invention which prevents this kind of accident occurrence is described in [Patent Document 1]. According to the present invention, the power cord is wound around the rear panel of the housing to house the power cord.
[0012]
For example, even if a chemical solution, rain, or the like is accidentally spilled from above, these are received by the power cord winding and the connectors do not get wet. That is, the power cord winding constitutes a roof-like member.
[0013]
[Patent Document 1]
JP-A-5-72489
[Problems to be solved by the invention]
However, in the invention of Patent Literature 1, a medical device (light source device) that is conventionally provided with a power cord winding is provided. Members must be mounted, which has a negative effect on cost.
[0015]
Further, whether the connector portion provided at the end of the power cord is straight or substantially L-shaped, the amount of protrusion from the rear panel together with the power cord becomes large. As a roof-like member that completely covers such a power supply connector, the projection amount from the panel surface is extremely large, and the appearance is inferior.
[0016]
The present invention has been made in view of the above circumstances, and the purpose of the present invention is to eliminate the necessity of adding a new member, and to prevent the occurrence of an electric leakage accident or the like even if the liquid is left on the connector. Another object of the present invention is to provide a medical device that prevents the occurrence of a medical problem.
[0017]
[Means for Solving the Problems]
According to the first aspect of the present invention, a bottom panel provided on a medical device having a housing, the bottom panel being provided on a mounting surface, a recess having an opening provided on the bottom panel, and a first electric device being provided on the recess are provided.

[0020]
The invention according to claim 3 is characterized in that a connector is constituted by the concave portion and the connector portion, and the connector is at least one of a power connector, a video connector and a communication connector. A medical device according to any one of claims 1 and 2.
[0021]
Further, in the medical device according to the third aspect of the present invention, it is possible to prevent at least one of the power connector, the video connector, and the communication connector from leaking and preventing disconnection.
[0022]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a perspective view of a medical device, for example, a light source unit of an endoscope apparatus viewed from the bottom side, and FIG. 3 is a side view in which a part of FIG. 2 is omitted, and FIG. 3 is a cross-sectional view in which a part of FIG. 2 is enlarged.
[0023]
Various gauges, indicator lights, and switches are mounted on a front panel (not shown) of the housing 1 that constitutes a light source unit of the endoscope apparatus. Support legs (support portions) 2 are attached to four corners of the bottom panel 1 a of the housing 1.
[0024]
Needless to say, these support legs 2 are made of, for example, a relatively rigid rubber material, each have a columnar shape, and are set to the same height Ha.
[0025]
A power connector 3 is attached to the bottom panel 1a near one of the support legs 2.
The power connector 3 is attached to the housing bottom panel 1a and has a first electric contact 4A and a recess 5 having an opening 5a. The power connector 3 is provided at the tip of a power cord 6 and is inserted through the opening 5a of the recess 5. And a connector section 7 having a second electric contact 4B comprising a hole inserted into the first electric contact 4A.
[0026]
When the recess 5 is attached to the housing bottom panel 1a, the opening 5a of the recess 5 is directed downward, that is, toward the installation surface 8 on which the housing 1 is installed. Therefore, when inserting the connector portion 7 into the concave portion 5, it is easy to work once the housing 1 is set up obliquely or right beside and the bottom panel 1a is exposed.
[0027]
However, by providing the opening 5a of the recess 5 at the edge very close to the side surface 1b of the bottom panel 1a, the connector 1 is inserted through the opening 5a of the recess 5 while the housing 1 is left as it is. be able to.
[0028]
When the housing 1 is installed on the installation surface 8 via the support legs 2 with the connector portion 7 inserted into the concave portion 5, a part of the connector portion 7 protrudes from the bottom panel 1a. That is, the connector portion 7 has a protruding portion T protruding from the bottom panel 1a.
[0029]
As shown in FIG. 3 only, the height of the support leg 2 from the housing bottom panel 1a is Ha, and the protrusion of the protrusion T of the connector 7 projecting from the housing bottom panel 1a is Hb. When
Height dimension Ha of support leg 2> Projection dimension Hb of projection T
It is set to be. For this reason, a gap S exists between the protruding end of the protruding portion T in the connector portion 7 and the installation surface 8.
[0030]
That is, in a state where the connector portion 7 is inserted into the concave portion 5 and the first electrical contact 4A and the second electrical contact 4B are electrically connected, the connector portion 7 has a projecting portion T projecting from the concave portion 5, The projecting amount Hb of the projecting portion T is formed smaller than the height dimension Ha of the support leg 2 which is a predetermined gap.
[0031]
In other words, the support leg 2 provided on the bottom panel 1a is provided when a part of the connector 7 is inserted into the recess 5 and the first electrical contact 4A and the second electrical contact 4B are electrically connected. Then, the housing 1 is held in a state where the connector 7 is not in contact with the installation surface 8.
[0032]
Since the power connector 3 itself uses a conventionally used component as it is, there is a slight gap between the inner peripheral surface of the concave portion 5 and the outer peripheral surface of the connector portion 7 constituting the power connector 3. That is no different.
[0033]
Since the power connector 3 and the power cord 6 are electrically connected to each other in the light source unit of the endoscope device configured as described above, when the power switch (not shown) is turned on, the power to the light source unit is changed. Feeding takes place.
[0034]
The power connector 3 is attached to the housing bottom panel 1 a, and the power cord 6 extends from the power connector 3. In this state, the projecting dimension Hb of the projecting portion T projecting from the bottom panel 1a of the connector portion 7 constituting the power connector 3 is set to be smaller than the height dimension Ha of the support leg 2 which is a predetermined gap. In addition, the projecting portion T of the connector 7 does not need to contact the installation surface 8.
[0035]
When the housing 1 is installed on the installation surface 8, the posture of the housing 1 is stabilized, and no mechanical load is applied to the power cord 6 and the power connector 3. In addition, the connector 7 does not fall out of the recess 5 after the housing 1 is installed, and the power connector 3 is prevented from coming off.
Even if the liquid 10 falls on the rear panel 1b of the housing 1 for some reason and flows down, the liquid 10 falls to the installation surface 8 as it is.
[0036]
Therefore, even if there is a liquid that penetrates and intervenes between the bottom panel 1a and the installation surface 8, this liquid does not go back along the support leg 2 and penetrate into the bottom panel 1a.
[0037]
However, only a small gap S exists between the lower end of the connector portion 7 of the power connector 3 and the installation surface 8. Therefore, for example, it is conceivable that the liquid that has fallen on the power supply cord 6 or the connector portion 7 protruding from the rear panel 1b is guided along each of them and enters the gap S by capillary action.
[0038]
However, since the connector portion 7 has the protruding portion T protruding from the bottom panel 1a with the protruding dimension Hb, it is impossible for the liquid entering the gap S to trace the protruding portion T having the protruding size Hb. Yes, after all, it prevents the power supply connector 3 or the recess 5 from leaking. Further, since the opening of the concave portion 5 faces downward, it is possible to prevent the liquid from entering due to the influence of gravity.
[0039]
The power connector 3 has the configuration in which the electric contact 4 is provided in the recess 5 and the connector 7 has a hole into which the electric contact is inserted. The same operation and effect can be obtained even if the power supply connector has a configuration in which the concave portion 5 has a hole into which an electric contact is inserted.
[0040]
Although the power supply connector 3 has been described here as a connector, for example, a video connector for inputting / outputting video or a communication connector for communicating with other peripheral devices can be applied. Needless to say, the effect is obtained.
[0041]
Further, the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the spirit of the present invention.
[0042]
Next, other characteristic technical items of the present invention will be additionally described as follows.
[0043]
(Additional Item 1) An endoscope apparatus comprising at least a connector having an electrical contact, wherein the connector is arranged on a bottom surface of the device.
[0044]

【The invention's effect】
As described above, according to the first and second aspects of the present invention, the electrical contacts can be protected and the connection cord can be prevented from coming off without adding a new member as a medical device.
[0048]
According to the second aspect of the present invention, protection of electrical contacts of a power supply connector, a video input / output connector, or a communication connector and prevention of disconnection of a connection cord are performed.
