  The distance between the pair of frame plates 201A corresponds to the thickness of the side wall 11A of the case 11 (FIG. 2). When the frame plate 201A is arranged on both surfaces of the side wall 11A, the elastic seal member 24 arranged in the holding groove 201B is positioned along the inner peripheral portion of the notch 11U (FIG. 2).

  The holding groove 201 </ b> B in which the elastic seal member 24 is arranged is a space that is continuous from one end of the filling seal arrangement part 202 to the other end of the filling seal arrangement part 202 through the bottom 220 </ b> A of the base 220. The elastic seal member 24 is elastically deformed inside the holding groove 201B.

The filling seal arrangement portion 202 (FIGS. 3 and 5) extends over the entire width of the notch 11U (FIG. 2), and continues to the upper end of the front frame plate 201A and the upper end of the rear frame plate 201A. .
A groove 202A for receiving a liquid sealing material used for the filling seal 14 (FIG. 1) is formed in the filling seal arrangement portion 202 along the width direction of the notch 11U. Except for the position of the groove 202A, the filling seal arrangement portion 202 is formed flat.

As shown in FIGS. 3 and 4, it is preferable that end locking portions 203 for locking the ends 24 </ b> A of the elastic seal members 24 are continuously provided at both ends of the filling seal arrangement portion 202. The end locking portion 203 restricts the end portion 24A of the elastic seal member 24 pressed between the elastic seal holding portion 201 and the inner peripheral portion of the notch 11U from being displaced upward from the notch 11U.
When the end portion 24A of the elastic seal member 24 abuts against the end locking portion 203 from below, a part of the end portion 24A is exposed from the contact notch 203A formed in the end locking portion 203.

  As shown in FIG. 5, the upper end 11B of the side wall 11A of the case 11 is disposed between the pair of frame plates 201A (FIG. 3) of the connector housing 22 between the portions 201D on the outer peripheral side of the end locking portions 203. You. At this time, a part (projection 24E) of the end 24A of the elastic seal member 24 exposed from the contact notch 203A is located between the upper end 11B and the filling seal arrangement portion 202.

(Elastic seal member)
The elastic seal member 24 (FIG. 3) is an elastic body formed as a whole by using a rubber-based resin material such as silicone rubber or the like and following the shape of the notch 11U of the case 11. The elastic seal member 24 is held by the elastic seal holding portion 201 of the connector housing 22 in a state of a molded body having a shape given in advance. In the present embodiment, the connector 20 is inserted into the notch 11U of the case 11 with the elastic seal member 24 attached to the elastic seal holding portion 201 as shown in FIG.

  As shown in FIGS. 3 and 4, the elastic seal member 24 includes an outer peripheral portion 24 </ b> D that is in close contact with the inner peripheral portion of the notch 11 </ b> U (FIG. 2), and an inner peripheral flange portion protruding from the inside of the outer peripheral portion 24 </ 24B.

As shown in FIG. 3, the elastic seal member 24 has a bottom 241 corresponding to the bottom peripheral edge 101 of the notch 11U (FIG. 2) and a side 242 corresponding to the side peripheral edge 102 of the notch 11U (FIG. 2). have.
The upper end of each side part 242 corresponds to the end part 24A of the elastic seal member 24 locked by the end locking part 203 described above. When the elastic seal member 24 is attached to the connector housing 22, the filling seal arrangement portion 202, which is the upper end of the connector housing 22, is exposed between both ends 24A of the elastic seal member 24.
The end portion 24A includes a contact portion 24C that is pressed against the end locking portion 203 from below, and a protrusion 24E that protrudes upward from the contact portion 24C.

  When the connector 20, the case 11, and the cover 12 are assembled as shown in FIG. 1, the elastic seal member 24 is compressed and elastically deformed between the elastic seal holding portion 201 and the inner peripheral portion of the notch 11U, and elastically deformed. The holder 201 is in close contact with the inner peripheral portion of the notch 11U. The space between the connector housing 22 and the case 11 is sealed by the elastic seal member 24.

The elastic seal member 24 is formed between the elastic seal holding portion 201 and the inner peripheral portion of the notch 11U by friction between the elastic seal member 24 and the inner peripheral portion of the notch 11U when the elastic seal member 24 is inserted into the notch 11U while being mounted on the connector 20. When pressed, it is elastically deformed to extend.
Grooves, protrusions, and the like are formed in the elastic seal member 24 to prevent displacement of the elastic seal member 24 with respect to the connector housing 22 and the case 11. Their description is omitted.

[Filling seal]
When the case 11, the cover 12, and the connector 20 are assembled, the filling seal 14 (FIG. 1) is filled and cured between the three members. The filling seal 14 is obtained by curing a liquid sealing material having fluidity (also referred to as a liquid gasket) while being filled between the filling region R1 including the filling seal arrangement portion 202 and the cover 12.
The filling seal 14 is made of, for example, a resin material such as silicone rubber. The filling seal 14 follows the shape of the contacting members, and also fills minute gaps such as steps between members. The filling seal 14 is preferably adhered to the surface of the member.

  The filling region R1 (FIG. 5) includes a filling seal arrangement portion 202 where the elastic seal member 24 is not arranged in the connector housing 22, both ends 24A of the elastic seal member 24, and an upper end portion 11B of the case 11. And the vicinity of the notch 11U. The filling region R1 of the present embodiment extends over the filling seal arrangement portion 202 and the upper end portion 11B of the case 11 in a direction (the width direction of the notch 11U) that connects both ends 24A of the elastic seal member 24 to each other. I have.

  The filling seal 14 is formed with a substantially uniform thickness between the filling region R1 and the back surface of the cover 12. The thickness of the filling seal 14 is, for example, about 0.02 mm to 1.3 mm.

[Method of manufacturing connector seal structure]
Next, an example of a procedure for obtaining the connector seal structure 1 by assembling the case 11, the connector 20, and the cover 12 will be described.
First, as shown in FIG. 6A, the connector 20 attached to the circuit board 13 and having the elastic seal member 24 (FIG. 2) is inserted into the notch 11U of the case 11 from above (connector insertion). Step S1).
At this time, even if the elastic seal member 24 extends, the end portion 24A of the elastic seal member 24 is pressed from above by the end locking portion 203 and locked.

  If the elastic seal member 24 is not attached to the connector 20, the elastic seal member 24 is sandwiched between the inner peripheral portion of the notch 11U and the connector housing 22 in step S1.

Next, as shown in FIG. 6B, the liquid sealing material 14 'is supplied to at least the region on the back side of the cover 12 corresponding to the filling region R1 (liquid sealing material supplying step S2). For example, the liquid sealing material 14 ′ is applied to a predetermined region of the cover 12 by an appropriate method such as extruding the liquid sealing material 14 ′ linearly from a container 141 containing a paste-like sealing material. For example, the liquid sealing material 14 ′ can be applied to a region having a width of about 10 mm and extending over the entire circumference of the cover 12 (including a region corresponding to the filling region R1).
Here, the liquid sealing material 14 ′ is supplied to the cover 12 from the viewpoint of the workability of the application of the liquid sealing material, but the liquid sealing material 14 ′ is supplied not to the cover 12 but to the filling region R 1, The liquid sealing material 14 'may be supplied to both the filling region R1 and the filling region R1.

Subsequently, as shown in FIG. 7A, the cover 12 is disposed on the upper end 11 </ b> B of the case 11 and the upper end (filling seal arrangement portion 202) of the connector housing 22. Then, the case 11, the cover 12, and the connector 20 sandwiched between the case 11 and the cover 12 are integrally assembled. By assembling these, the liquid seal is formed entirely between the substantially flat filling region R1 including the filling seal disposing portion 202, the end portion 24A of the elastic sealing member 24, and the upper end portion 11B, and the back surface of the flat cover 12. The material 14 'is spread and filled (assembly and filling step S3).
The liquid sealing material 14 ′ can also be used to fill the gap 202 A (FIG. 3) of the filling seal arrangement portion 202, the gap formed by the filling seal arrangement portion 202, the end 24 A of the elastic seal member 24, and the slight step of the upper end 11 B. Go around.

  When the cover 12 is not provided on the case 11, the filling seal arrangement portion 202 may protrude above the upper end portion 11B. Even in this case, the filling seal disposing portion 202 is disposed substantially flush with the upper end portion 11B by being pressed by the cover 12 provided on the case 11 via the liquid sealing material 14 '. The end 24A (convex portion 24E) of the elastic seal member 24 that is exposed while being positioned between the filling seal disposing portion 202 and the upper end portion 11B is also substantially flush with the upper end portion 11B and the filling seal disposing portion 202. Will be done.

  Here, it is preferable that the size and shape of the elastic seal member 24 be set so that the convex portion 24E (FIGS. 3 and 4) slightly protrudes from the upper end portion 11B and the filling seal arrangement portion 202. Then, it is possible to prevent the convex portion 24E from being positioned below the filling seal disposing portion 202 and the upper end portion 11B due to dimensional tolerances or assembly tolerances of the members. As a result, the convex portion 24E, the filling seal arrangement portion 202, and the upper end portion 11B can ideally realize a flush configuration.

As shown in FIG. 7B, the liquid sealing material 14 'filled between the filling region R1 and the cover 12 is cured to a thin and uniform thickness (curing step S4). The liquid sealing material 14 'can be cured by leaving it at a normal temperature for a predetermined time or by heating as necessary. When the liquid sealing material 14 ′ is made of a photocurable resin and the cover 12 or the case 11 has translucency, the liquid sealing material 14 ′ is irradiated with light of a suitable wavelength (for example, ultraviolet light) to thereby provide the liquid sealing material. 14 'can be cured.
The filling seal 14 obtained by curing the liquid sealing material 14 ′ is in close contact with the back side of the cover 12, the upper end 11 B of the case 11, the filling seal arrangement part 202, and the end 24 A of the elastic seal member 24. Since a part of the filling seal 14 is arranged in the groove 202A (FIG. 3) of the filling seal arrangement part 202, the displacement of the filling seal 14 can be prevented.

  It is preferable that the end portion 24A (convex portion 24E) of the elastic seal member 24 is arranged substantially flush with the upper end portion 11B and the filling seal arrangement portion 202. Then, when the cover 12 is assembled to the case 11 or the like, it is possible to prevent the load in the shear direction from being applied to the protrusion 24E and damage to the protrusion 24E. In addition, when the position of the top surface of the convex portion 24E is low with respect to the upper end portion 11B and the filling seal disposing portion 202, the filling seal 14 can be prevented from being thickened at the position of the convex portion 24E. When the filling seal 14 is thinner than thicker, the filling seal 14 is less likely to be deformed by an external force caused by thermal expansion or impact of air in the housing 10. It is preferable that the filling seal 14 is formed thin over the entire filling region R1 by arranging the end 24A of the elastic seal member 24 substantially flush with the upper end 11B and the filling seal arrangement portion 202. Then, deformation of the filling seal 14 can be avoided, and the state in which the filling seal 14 is in close contact with the member can be maintained.

  According to the procedure described above, the connector seal structure 1 can be obtained.

[Operation and effect of the present embodiment]
In the connector seal structure 1 of the present embodiment, the U-shaped elastic seal member 24 and the filling seal 14 that is filled in a liquid state are annularly combined. Then, the waterproofing between the connector housing 22 and the housing 10 can be sufficiently achieved over the entire circumference of the connector housing 22 arranged in the notch 11U without deforming the cover 12. The U-shaped elastic seal member 24 is missing in a range corresponding to the cover 12. Therefore, even when the cover 12 is assembled to the case 11, no excessive reaction force is generated from the elastic seal member 24 to the cover 12. This is different from the case where an annular elastic seal is provided on the outer peripheral portion of the connector housing 22 disposed in the notch 11U, whereby an upward reaction force is generated on the cover 12 from the upper end of the elastic seal.
According to the present embodiment, unlike the case where an annular elastic seal is used, it is not necessary to reduce the elastic force of the elastic seal or increase the rigidity of the cover 12 to avoid deformation of the cover 12.

  Furthermore, the step between the portion of the connector housing 22 where the U-shaped elastic seal member 24 is not disposed (the filling seal disposing portion 202) and the upper end 11B of the case 11 is minimized, and the gap near the step is reduced. This is advantageous in terms of ensuring waterproof performance and facilitating the operation of applying the liquid sealing material. When an annular elastic seal is used, the upper end of the elastic seal projects from the upper end 11B of the case, so that a large step and a gap are generated.

In addition to the above, the configuration described in the above embodiment can be selected or changed to another configuration as appropriate without departing from the gist of the present invention.
The filling region R1 does not necessarily need to include the upper end 11B of the case 11 and the end 24A of the elastic seal member 24, and it is sufficient if at least the filling seal arrangement portion 202 is included.
For example, both ends 24A of the elastic seal member 24 are in close contact with the back side of the cover 12, and between the cover region 12 and the filling region R1 including only the filling seal arrangement portion 202 located between the both ends 24A. A configuration in which the filling seal 14 is filled is allowed.
Alternatively, a configuration in which the filling seal 14 is filled between the cover 12 and the filling region R1 formed by both ends 24A of the filling seal arrangement portion 202 and the elastic seal member 24 is also allowed.
In any of the above configurations, the reaction force from the elastic seal member 24 to the cover 12 is reduced by the annularly combined elastic seal member 24 and the filling seal 14 while sufficiently waterproofing the entire circumference of the connector housing 22. The deformation of the cover 12 can be prevented while suppressing the deformation.

From the viewpoint of more sufficiently suppressing the reaction force of the elastic seal member 24 against the cover 12, the upper end of the end 24A of the elastic seal member 24 does not directly contact the cover 12, and the upper end of the end 24A and the cover 12 The above embodiment in which the filling seal 14 is interposed therebetween is preferable. At this time, the upper end of the end 24A of the elastic seal member 24 and the filling seal 14 are in direct contact.
In the above embodiment, the filling seal 14 is arranged not only at the filling seal arrangement portion 202 but also at the end 24 </ b> A of the elastic seal member 24. In that case, the liquid sealing material used for the filling seal 14 enters the gap between the ends 24A, the upper end 11B, and the filling seal arrangement part 202, and the gap is closed. Therefore, it is possible to contribute to securing sufficient waterproofness.

  In the present invention, a configuration in which the upper end of the end portion 24A of the elastic seal member 24 does not directly contact the filling seal 14 is also allowed. For example, since the contact notch 203A (FIG. 3) for exposing the end 24A does not exist in the end locking portion 203, the end 24A and the filling seal 14 are separated by the end locking portion 203. If it is. In this case as well, the same effects as in the above embodiment can be obtained as long as the end 24A and the filling seal 14 are in close contact with the end locking portion 203.
