Description

TECHNICAL FIELD The present invention relates to a connector cleaning device for cleaning a connector for connecting medical tubing.

Conventionally, efforts have been made to prevent erroneous connections in connectors for connecting medical tubes. As part of these efforts, the promotion of medical accident prevention and the introduction of standards for stable supply through international harmonization are being promoted. Among them, in the use of enteral nutrition, there is a standard that the connector on the side connected to the patient is the male side, and the connector on the side opposite to the patient is the female side. Due to the structure of such standards, for example, nutritional supplements for enteral nutrition may remain in the internal space of the male connector on the patient side. As a result, there is a risk of hygienic inconvenience such as the generation of bacteria in the male connector that is indwelled while being connected to the patient. Techniques for wiping with a member that absorbs nutrients have been disclosed in order to eliminate such a risk, but there is a possibility that the nutrients cannot be completely wiped off and solidified.

Embodiments of the present invention will be described below. The embodiments shown below are examples of the embodiments of the present invention, and the technical scope of the present invention is not limited to the following aspects.

<Example 1>
FIG. 1 shows a vertical cross-sectional view of a male connector 100 for enteral nutrition, which is an example of an object to be cleaned by the connector cleaning device according to the present embodiment. In FIG. 1, the lower side corresponds to the front end side of the male connector 100, and the upper side corresponds to the rear end side. The male connector 100 in this embodiment includes a connector main body 101 as a male connector main body having therein a channel 101a that communicates with the tube 102 . The connector main body 101 has a tapered (also referred to as a truncated cone) side surface 101b in which the outer diameter becomes smaller toward the distal end side.

Around the connector main body 101, a substantially cylindrical coupler 103 surrounding the outer periphery of the connector main body 101 is provided. A coupler connecting portion 103b provided on the rear end side of the inner surface of the coupler 103 forms a connector connecting portion 100a as a connecting portion together with a main body connecting portion 101c provided on the rear end side of the side surface 101b of the connector main body 101. . At the connector coupling portion 100a, the coupler 103 is coupled to the connector main body 101 so as to be rotatable around the axis and not to come off toward the tip side. The space surrounded by the side surface 101b of the connector main body 101, the inner surface of the coupler 103, and the connector coupling portion 100a is hereinafter referred to as the internal space of the male connector 100. FIG. Note that the coupler 103 may be fixed to the connector main body 101 so as not to be rotatable around the axis. That is, in this embodiment, a free-lock connector is shown as an example, but a fixed-lock connector may be used.

A disk-shaped rib portion 101d that protrudes outward along the entire side surface of the connector body 101 is formed on the further rear side of the body coupling portion 101c of the connector body 101, and the coupler 103 is connected to the connector body. It functions as a stopper for 101 so that it does not move excessively to the rear end side. Further, the inner diameter of the rear end side of the flow path 101a provided in the connector main body 101 is enlarged to form a large diameter portion 101e, into which the tube 102 can be press-fitted. A female screw portion 103a is formed on the inner surface of the coupler 103 so that it can be screwed with a female connector (not shown) having a male screw portion. The disk-shaped rib portion 101d is not essential, and the coupler 103 may freely move toward the rear end side with respect to the connector main body 101. FIG. That is, the coupler 103 may be a slide coupler.

In this embodiment, the tube 102 shown in FIG. 1 is connected to the living body, and the male connector 100 is screwed to a female connector (not shown), so that a fluid such as a nutrient solution is supplied from the female connector side to the male connector 100 and the tube. It is supplied to the living body via 102 .

FIG. 2 shows a schematic diagram of the cleaning part main body 1 as a cleaning unit for fixing and cleaning the male connector 100 in this embodiment. 2(a) is a plan view of the cleaning unit main body 1, and FIG. 2(b) is a cross-sectional view of the cleaning unit main body 1 taken along the line AA. The washing unit main body 1 includes, in a plan view, a large-diameter columnar main body 21, a small-diameter connector mounting portion 20 provided on the upper side of the main body 21 for mounting the male connector 100, and the male connector 100. It is composed of a drainage tube 22 for discharging the cleaning liquid after cleaning. Here, the cylindrical side wall of the connector attachment portion 20 corresponds to the side wall portion. The side wall has a length that is more than twice the length from the cleaning liquid ejection hole to the tip surface on the base end side of the coupler, and the cleaning liquid that has passed between the male connector body and the coupler leaks to the outside from the upper side of the side wall. is made difficult. A collection space is formed above the side wall to collect the cleaning liquid that has passed between the male connector body and the coupler.

As can be seen from the AA sectional view of FIG. 2(b), the connector mounting portion 20 is provided with a cylindrical accommodating portion having therein a connector insertion hole 10 into which the male connector 100 is inserted. The connector insertion hole 10 is a columnar space with an inner diameter slightly larger than the outer diameter of the coupler 103 of the male connector 100 . When the male connector 100 is attached, a gap is formed between the receiving portion and the coupler to form a flow path. The bottom surface 11 of the connector insertion hole 10 is provided with an abutment groove 12 which is an annular groove in a plan view, with which the tip of the connector body 101 can abut when the male connector 100 is attached. Although the connector insertion hole 10 extends in the direction of gravity, the male connector may be horizontally inserted.

A protrusion 13 to be inserted into the flow path 101a of the connector body 101 is formed on the center side of the inner periphery of the contact groove 12, which is an annular groove. The projecting portion 13 forms an isolation portion that isolates the channel of the connector body from the channel of the cleaning liquid. Furthermore, an elastic ring 14 is provided on the outer periphery of the bottom surface 11 with which the tip of the coupler 103 of the male connector 100 abuts. The elastic ring 14 abuts on the coupler 103 of the male connector 100 to elastically support the male connector 100 so as to be vertically movable.

The bottom surface 11 of the connector insertion hole 10 is provided with a cleaning liquid jetting hole 15 as a cleaning liquid jetting section. The cleaning liquid ejection hole 15 is connected to a cleaning liquid inflow hole 18 opening in the bottom surface of the body portion 21 of the cleaning section main body 1 and formed to have a smaller diameter than the cleaning liquid inflow hole 18 . The cleaning liquid is pumped from the outside into the cleaning liquid inflow hole 18 , so that the cleaning liquid is ejected from the cleaning liquid ejection hole 15 . In addition, on the bottom surface 11 of the connector insertion hole 10, the opposite side to the cleaning liquid ejection hole 15 across the center (when the male connector 100 is fixed, it can be said that it is the opposite side to the cleaning liquid ejection hole 15 across the connector main body 101). ), a cleaning liquid discharge hole 16 opens. Since the cleaning liquid discharge hole 16 is provided on the opposite side of the cleaning liquid jetting hole 15 with the center interposed therebetween, the jetted cleaning liquid can be made to flow to the discharging hole after rotating the internal space of the male connector. The opening width of the cleaning liquid ejection hole should be smaller than the maximum width of the gap between the male connector body and the coupler, so that the cleaning liquid ejected from the ejection hole can easily strike between the male connector body and the coupler. good too. The cleaning liquid ejection hole may be located at the base end side from the tip end of the male connector main body, or at the same position, or at a position 4 mm away from the tip end of the male connector main body toward the tip end side. It is preferable that the cleaning liquid jetting hole is close to the cleaning object, because the cleaning liquid can be vigorously applied to the cleaning object. In particular, it is preferable that the cleaning liquid ejection hole is formed at a position between a position 3 mm away from the tip of the male connector main body toward the tip side and the connecting portion. Here, the cleaning liquid jetting part in this embodiment includes the cleaning liquid jetting hole 15 and the cleaning liquid inflow hole 18 . Also, the cleaning liquid jetting holes 15 correspond to jetting holes. Also, the bottom surface 11 of the connector insertion hole 10 corresponds to the opposing surface. Although the gap between the male connector main body and the coupler is extremely small in the figure, the gap between the male connector main body and the coupler may be designed to be large, for example, the maximum width of the gap may be designed to be about 2 mm. .

A second cleaning liquid discharge hole 17 is opened on the inner wall 10a of the connector insertion hole 10 on the side opposite to the cleaning liquid ejection hole 15 across the center. The cleaning liquid discharge hole 16 and the second cleaning liquid discharge hole 17 are both connected to a cleaning liquid discharge path 19 that is a pipe line penetrating the inside of the liquid discharge tube portion 22 . In this embodiment, the cleaning liquid discharge hole 16 and the second cleaning liquid discharge hole 17 are only partitioned by the elastic ring 14, and may be formed simultaneously when the cleaning liquid discharge path 19 is actually formed. . It should be noted that the discharge part in this embodiment includes the cleaning liquid discharge hole 16 , the second cleaning liquid discharge hole 17 , and the cleaning liquid discharge path 19 . Also, the cleaning liquid discharge hole 16 corresponds to a discharge hole, and the second cleaning liquid discharge hole 17 corresponds to a second discharge hole. In addition, it is preferable that the discharge hole is provided downward in the direction of gravity in the space inside the connector insertion hole 10 . For example, when the lower connector insertion hole 10 extends horizontally, it is preferably formed on the lower side of the side wall in the direction of gravity instead of on the bottom surface. In this case, the side wall portion may be inclined so that the drainage can easily flow into the discharge hole, and the slit of the cover member may extend toward the side opposite to the discharge hole. By doing so, it is possible to make it difficult for the waste liquid after washing to leak out to the outside. In addition, although the cleaning liquid discharge hole 16 and the second cleaning liquid discharge hole 17 are formed as one large hole having each hole, they may be formed separately and communicated with each other later. The second cleaning liquid discharge hole 17 does not have to communicate with each other. The space between the coupler and the storage portion may be liquid-tight, and the second cleaning liquid discharge hole 17 may be provided on the side opposite to the cleaning liquid discharge hole 16 . Further, although the cleaning liquid discharge path 19 extends horizontally, it may extend parallel to the cleaning liquid inlet 18 .

FIG. 3 shows a schematic configuration of the lid member 2 that can be attached from above to the connector attachment portion 20 of the cleaning unit main body 1. As shown in FIG. 3(a) is a plan view of the lid member 2, and FIG. 3(b) is a cross-sectional view of the BB cross section. The lid member 2 has a shape in which slits 2a are formed in the closed end surface and the side surface of a cylindrical member with one end surface closed. The width of the slit 2a is slightly larger than the outer diameter of the tube 102. As shown in FIG. Since the tube can be positioned in the insertion hole at the center of the lid member via the slit, the lid member can be easily attached to the accommodating portion after the male connector has been inserted.

A locking mechanism 2 b for fixing the lid member 2 to the connector mounting portion 20 is provided on the inner surface of the side surface of the lid member 2 . In the example shown in FIG. 3, the lock mechanism 2b is a protrusion provided on the inner surface of the side surface of the lid member 2. As shown in FIG. In this embodiment, the lid member 2 is placed over the connector mounting portion 20 from above, and the projection is inserted into a key-shaped groove (not shown) provided on the side surface of the connector mounting portion 20, and then the lid member 2 is closed. The cover member 2 is fixed to the connector mounting portion 20 by rotating it. With this, it is possible to fix the male connector 100 in the connector insertion hole 10 .

It should be noted that various other mechanisms can be adopted as the lock mechanism 2b. For example, the lock mechanism 2b may be a female screw provided on the inner surface of the side surface of the lid member 2. As shown in FIG. In this case, by covering the connector mounting portion 20 with the lid member 2 from above and rotating it, the female threaded portion of the lid member 2 is screwed to the male threaded portion provided on the side surface of the connector mounting portion 20. The lid member 2 may be fixed to the connector attachment portion 20 . Here, the lid member 2, the connector mounting portion 20, and the bottom surface 11 in the embodiment constitute a fixed portion.

FIG. 4 shows a state in which the male connector 100 is inserted from the connector insertion hole 10 of the cleaning unit main body 1 and the lid member 2 is attached and fixed to the connector attachment portion 20 . As shown in FIG. 4 , the male connector 100 is inserted through the connector insertion hole 10 with its distal end downward, and then the cover member 2 is attached to the connector attachment portion 20 . At this time, the tip of the connector main body 101 enters the abutment groove 12, and the protrusion 13 is inserted into the flow channel 101a of the connector main body 101 and fixed so as to block the flow channel 101a. A projecting portion 13 having a radiused outer edge is formed inside the contact groove 12, and a wall portion having a radiused inner edge is formed outside the contact groove 12, and the male connector 100 is guided and abutted by these members. It penetrates into the contact groove 12 . Also, the tip of the coupler 103 is brought into contact with the elastic ring 14 .

By fixing the male connector 100 in this state in the connector insertion hole 10 of the cleaning unit main body 1, the cleaning liquid discharge hole 16 and the second cleaning liquid discharge hole 17 are provided on the inner peripheral side and the outer peripheral side of the coupler 103. It can be sealed except for the covered part. Also, the flow path 1 of the connector main body 101
01a tip can be sealed.

When the male connector 100 is inserted from the connector insertion hole 10 and the cover member 2 is attached to the connector attachment portion 20, if the tube 102 is long, it may be necessary to pass the long tube 102 through the cover member 2. Conceivable. However, the lid member 2 in this embodiment is provided with a slit 2a. Therefore, the cover member 2 can be fixed by covering the connector mounting portion 20 so that the tube 102 is introduced into the slit 2a from the side. This makes it possible to more easily fix the lid member 2 to the connector mounting portion 20 and fix the male connector 100 in the connector insertion hole 10 . Note that the lid member 2 may be configured to rotate relative to the connector attachment portion 20 . By doing so, the position of the slit 2 a can be adjusted after the cover member 2 is attached to the connector attachment portion 20 . Moreover, the cover member 2 may be configured by a plurality of members. For example, the lid member may be composed of two members, a member having the slit 2a and a member closing the slit 2a, and the slit 2a may be closed by relatively rotating one member and the other member.

In this embodiment, while the male connector 100 is fixed to the cleaning unit main body 1, the cleaning liquid is introduced from the cleaning liquid inlet hole 18 and ejected from the cleaning liquid jetting hole 15, so that the connector body 101 of the male connector 100 is removed. The inner space 100b, which is the space surrounded by the side surfaces, the inner surface of the coupler 103, and the connector coupling portion 100a, is cleaned. FIG. 5 shows the flow of the cleaning liquid in that case.

As indicated by arrows in FIG. 5 , the cleaning liquid is introduced from the cleaning liquid inlet hole 18 , and the cleaning liquid jetted from the cleaning liquid jetting hole 15 flows into the internal space 100 b of the male connector 100 . The cleaning liquid flowing into the internal space 100b of the male connector 100 flows through the internal space 100b to wash the side surface of the connector body 101, the inner surface of the coupler 103, and the connector coupling portion 100a. It is introduced into the discharge passage 19 and discharged from the liquid discharge tube portion 22 .

5 from the gap between the body coupling portion 101c and the coupler coupling portion 103b in the connector coupling portion 100a of the male connector 100, the leaked cleaning fluid It drops from between the inner wall of the insertion hole 10 and the outer peripheral surface of the coupler 103 , is introduced into the cleaning liquid discharge passage 19 through the second cleaning liquid discharge hole 17 , and is discharged from the liquid discharge tube portion 22 .

In this state, the channel 101a of the connector body 101 is sealed by the protrusion 13, so that the cleaning liquid after cleaning the internal space 100b can be prevented from entering and remaining in the channel 101a. The projecting portion 13 in this embodiment corresponds to the sealing portion. In addition, the space between the inner peripheral side (corresponding to the internal space 100b) of the coupler 103 and the outer peripheral side of the coupler 103 is spaced apart from the part where the cleaning liquid discharge hole 16 and the second cleaning liquid discharge hole 17 are provided by the elastic ring 14. Since it is sealed, it is possible to prevent the cleaning liquid flowing through the internal space 100 b from leaking out of the coupler 103 . The elastic ring 14 in this embodiment corresponds to the second seal portion. In this embodiment, the sealing portion has a form in which the protrusion 13 enters the flow path 101a of the connector main body 101 to seal as described above, but the sealing part is not limited to this form. For example, the contact groove 12 with which the tip of the connector main body 101 abuts may be improved in liquid-tightness, or the protrusion 13 may have a flat shape instead of entering the flow path 101a of the connector main body 101. The flow path 101a may be sealed by having a liner and being in close contact with the tip of the connector main body 101. FIG. A flexible O-ring may be provided to abut the tip of the connector body 101 so that it can be sealed to a wide range of connector sizes.

FIG. 6 shows a cleaning device 40 in which the cleaning unit main body 1, pressure feed pump, cleaning liquid tank 41, and drainage liquid tank 45 are simply shown. In this example, the cleaning unit main body 1 and the cleaning liquid tank 41 are communicated with each other by a flexible cleaning liquid tube 43 that guides the cleaning liquid stored in the cleaning liquid tank 41 to the cleaning liquid inlet 18 . The cleaning liquid tube 43 is exposed from the cleaning liquid tank 41, and the cleaning unit main body 1 can be freely moved. The washing liquid tube 43 preferably has a length of about 300 mm to 2000 mm, more preferably about 800 mm to 1800 mm. Further, when the cleaning liquid tube 43 is long, a holding section for assembling the cleaning section main body may be provided in a cleaning device having a pump. Further, the cleaning liquid tank 41 is provided with a pump 42 for pumping the cleaning liquid stored in the cleaning liquid tank 41 to the cleaning liquid inflow hole 18 . The cleaning liquid tank 41 and the pump 42 for pumping may be separable or non-separable.

Further, a flexible discharge tube 44 is provided that communicates the cleaning liquid discharge path 19 and a drainage tank 45 and guides the cleaning liquid after cleaning discharged from the cleaning liquid discharge path 19 to the drainage tank 45 . The discharge tube 44 is exposed to the outside from the liquid discharge tank 45, and the situation in which the operation of the cleaning unit main body 1 is hindered is reduced. In this example, by operating the pump 42 , the cleaning liquid is ejected from the cleaning liquid ejection hole 15 into the internal space 100 b of the male connector 100 , the internal space 100 b is cleaned, and the cleaning liquid after cleaning is discharged into the drainage tank 45 . , can be temporarily stored.

As a result, it is possible to configure the cleaning device 40 in which the cleaning liquid tank 41 and the drainage tank 45 are stationary and the cleaning unit body 1 can be freely moved with respect to them. As a result, it is possible to clean the male connector 100 by moving only the cleaning unit main body 1 to a place where the cleaning work can be easily performed, so that the cleaning work can be performed more easily or more efficiently. In addition, it is also possible to provide either the pressure feed pump or the cleaning liquid tank in the cleaning unit main body 1 . In FIG. 6, the cleaning liquid tank 41 and the drainage tank 45 are separately configured, but a mounting table on which the cleaning liquid tank 41 and the drainage tank 45 can be placed is provided. The tank 45 can be placed, or the pressure feed pump, the cleaning liquid tank, and the cleaning liquid tank can be integrated. Alternatively, the drain tank 45 may be omitted, and the cleaning liquid after cleaning may be discharged directly from the drain tube 44 to a sewage port or the like for disposal. Further, the washing liquid tank is preferably a container that is portable and has an opening, but it may be a water faucet or a syringe. Alternatively, all may be integrated.

In the above embodiment, a flexible tube made of a flexible resin material is used, but the material of the flexible tube is not particularly limited, and can be a bendable metal member. good too. In the above-described embodiment, the cleaning unit main body 1 is inseparably connected to the cleaning device having a pump for pumping the cleaning liquid or the cleaning liquid tank through a flexible tube. However, the connector attachment portion and the cleaning device may be separable. That is, an adapter having a cleaning device mounting portion that can be attached to a cleaning device having a pump or a cleaning liquid tank, and an accommodating portion may be provided, and the accommodating portion and the cleaning device may be detachable. Also, there may be no flexible tubing between the adapter and the washing device, and the washing device to which the adapter is attached need not have flexible tubing. The adapter may be made of a relatively inexpensive material such as resin, and may be replaced at a predetermined timing such as each time the male connector 100 is washed, or each predetermined number of times of washing, or each patient. The provision of a disposable adapter reduces the risk of patient-derived germs adhering to another patient's connector, especially when the receptacle is changed for each patient. In particular, it is preferable to use an adapter for a portion including a side wall portion and an isolation portion which abut against the male connector, since adhesion of bacteria can be further reduced. Also, the adapter may have a connector section that can be detachably connected to the cleaning liquid tube or the drainage tube. The connector portion preferably has a locking mechanism for screwing, fitting, or the like. It is preferable to design so that the waste liquid after washing can be easily discharged from the storage part, and by improving drainage, contamination due to replacement of the adapter can be reduced. For example, although the cleaning liquid discharge port 19 in FIG. 6 extends horizontally, it may extend in the direction of gravity or in the direction of inclination. The insertion direction of the tube in the adapter may be the direction of gravity as shown in FIG. 6, but it may also be horizontal. good.

The adapter may be directly connectable to the washing liquid tube and the drainage tube, but as shown by the dashed line in FIG. It may be in the form FIG. 7(a) shows an example in which the cleaning device section 1 is divided into a portion 1a that contacts the male connector 100 and another portion 1b. In this example, by frequently replacing only the portion 1a that contacts the male connector 100, it is possible to more reliably prevent the cleanliness of the cleaning unit main body 1 itself from deteriorating.

In addition, it is possible to limit the parts to be exchanged, and to suppress the cost increase associated with the exchange of the cleaning unit main body 1 . In this case, the cost of the replacement part can be reduced by changing the materials of the replacement part and the non-replacement part, such as making the part 1a that contacts the male connector 100 made of resin and the other part 1b made of metal. In addition, it is possible to extend the life of non-replaceable parts. In addition, an antibacterial material can be used or an antibacterial agent can be applied to the non-replaceable portion. Note that the non-replaceable portion may be resin. It is not essential to provide replacement parts.

FIG. 7(b) is an example of dividing into a portion 1c which is structurally easy to separate and has a high risk of damage due to attachment and detachment of the lid member 2, and a portion 1d where cleanliness is likely to deteriorate. In this example, the portion 1c, which has a high risk of damage due to attachment and detachment of the lid member 2, may be made of metal and not replaced, and the portion 1d, which tends to deteriorate in cleanliness, may be made of resin and replaced. This also makes it possible to more reliably suppress deterioration in the cleanness of the cleaning unit main body 1 itself. In addition, it is possible to suppress an increase in cost associated with replacement and to extend the life of non-replacement parts. The replaceable part and the non-replaceable part can be connected by various known methods such as screwing. Note that the non-replaceable portion may be resin. It is not essential to provide replacement parts.

Further, in this embodiment, the water pressure of the cleaning liquid which is caused to flow in from the cleaning liquid inlet hole 18 and to be ejected from the cleaning liquid ejection hole 15 can be variously changed as shown in FIG. For example, as shown in FIG. 8A, the water pressure may be constant, or as shown in FIG. can be By doing so, it is possible to reduce the impetus of the cleaning liquid caused by the collision of the cleaning liquid flowing in the internal space. Furthermore, as shown in FIG. 8(c), the water pressure may be changed periodically while continuing to jet the cleaning liquid. The water pressure of the cleaning liquid may be changed by controlling the rotation speed of the pumps 32,42. A user may be able to freely select the jetting method of these washing liquids with a button. Further, the extending direction of the cleaning liquid jetting holes 15 may be made oblique, the diameter of the inflow side of the cleaning liquid jetting holes 15 may be made smaller than the diameter of the outflow side to strengthen the momentum of the jetting liquid, or conversely, the inflow of the cleaning liquid jetting holes 15 may be increased. The diameter of the side can be made larger than the diameter of the outflow side so that the washing liquid can be sprayed over a wide range.

A cleaning device with a pump may be cord powered or battery powered, which may be built into the cleaning device. If the cleaning device having a pump is not stationary, it is preferable that the device be of a shape that is easy for the user to carry. A washing device with a pump may have a tank containing a volume of water for the washing of about 10 people, and the tank may be separable from the washing device. Also, the drain tank may be placed in a washing apparatus equipped with a pump, or a separately prepared container such as a bag or bottle may be used as the drain tank. It is preferable that the drainage tank has a shape that is easy to clean. The cleaning device is not limited to an electric type, and may be a manual type. The pump is preferably an electric type pump, but may be a manual type pump such as a syringe. The separating portion that abuts on the male connector main body may not be formed integrally with the adapter, but may be provided separately. The lid member may be connected to the adapter via a hinge, or may be slidably fixed to the adapter. Also, while the irrigation device is particularly useful with enteral feeding connectors, it can also be used with medical connectors other than enteral feeding connectors. The cleaning liquid ejection hole 15 may be provided in the adapter, but may also be provided on the cleaning device side, and the cleaning liquid ejection hole may be formed at the end of the cleaning liquid tube. The cleaning liquid ejection hole may be formed at a position facing between the male connector main body and the coupler. The accommodating portion may have a gap that forms a flow path between itself and the coupler, and may be rotatable relative to the coupler. Alternatively, the lid member may be provided with an engagement portion for the coupler, and the coupler may rotate within the housing portion by rotating the lid member in the circumferential direction. The lid member and the connector mounting portion may be formed to be liquid-tight. For example, a sealing material such as an elastic member may be provided between the lid member and the connector mounting portion. The accommodating portion having the connector attachment portion may be composed of a single member, or may be composed of a plurality of members. For example, the housing portion may be composed of two half-split members so that the housing portion can be separated. By doing so, the lid member can also be deleted. In this case, a sealing material may be provided on the separating surface of the accommodating portion so that the liquid tightness is maintained after the separated accommodating portions are engaged.
