JP-A-9-82402 (FIGS. 5 and 6)

  By the way, conventionally, since the sealing member is merely pressed against the panel surface of the panel, when the pressing force is small, the sealing performance may be inferior, and there is a demand for further improving the sealing performance (waterproofing / soundproofing). It was.

  Increasing the degree of compression of the sealing member is effective for improving the sealing performance (waterproofing / soundproofing performance), but increasing the pressing force to increase the overall degree of compression increases the repulsive force of the sealing member, There was a risk of hindering connector installation work.

  In consideration of the above circumstances, the present invention forms a portion having a high degree of compression locally, thereby increasing the degree of adhesion with the panel and improving the sealing performance without increasing the overall degree of compression. It is an object to provide a sealed structure.

  According to the first aspect of the present invention, an annular seal member is provided on the front surface of one of a pair of connectors disposed on both sides of the panel and fitted to each other through openings formed in the panel, and the seal member is In the sealing structure between the connector and the panel that seals the gap between the connector and the panel by being pressed against the panel, an annular seal insertion groove is formed on the front surface of the one connector, and the seal member is formed in the seal insertion groove On the other hand, an annular rib standing toward the front surface of the one connector protrudes from the peripheral edge of the opening of the panel, and the annular rib is inserted into the seal member fitted in the seal insertion groove. It is characterized by being pressed and bitten.

  The invention according to claim 2 is the seal structure between the connector and the panel according to claim 1, wherein the seal member is set to be larger than the groove width of the seal insertion groove so that the seal member is It is characterized by being fitted into the seal insertion groove in a compressed state.

  A third aspect of the present invention is the seal structure between the connector and the panel according to the first or second aspect, wherein the seal member fitted in the seal insertion groove is provided at an opening edge of the annular seal insertion groove. It is characterized in that a locking claw for preventing it from coming off is provided.

  According to a fourth aspect of the present invention, there is provided a seal structure between the connector and the panel according to the first or second aspect, wherein the height of the side wall on the inner periphery and the outer periphery of the annular seal insertion groove is different. A gap is secured between the low side wall and the panel, and the protruding portion of the seal member due to the biting of the rib is received in the gap, and the received protruding portion is connected to the tip of the low side wall and the end. It is characterized by being clamped with the panel surface of the panel.

  The invention of claim 5 is provided with an annular seal member on the front surface of one of a pair of connectors disposed on both sides of the panel and fitted to each other through openings formed in the panel. In the sealing structure between the connector and the panel that seals the gap between the connector and the panel by pressing against the plate surface of the panel and sandwiching in a compressed state between the front surface of the one connector and the plate surface of the panel, An annular convex portion that protrudes toward the plate surface of the panel is formed on the front surface of one connector, the seal member is disposed so as to cover the annular convex portion, and the seal member is disposed on the plate surface of the panel. By pressing the seal member, the seal member is compressed locally at a position where the convex portion is located than at other positions.

  According to the first aspect of the present invention, since the degree of compression of the seal member in the portion where the ribs are bitten can be locally increased, the adhesion between the panel and the seal member in that portion can be enhanced. Moreover, since the outer peripheral part of the seal member can be restrained by the groove inner wall by fitting the seal member into the seal insertion groove, the overall compression degree of the seal member can be increased when the rib is bitten, and the seal is increased accordingly. The contact pressure between the member, the panel, and the connector can be increased. Therefore, even if the pressing force between the connector and the panel is not increased, the sealing property can be improved, and the mounting property of the connector to the panel is not deteriorated. In addition, since the ribs are bitten into the seal member, a labyrinth effect can be expected in which the length of the invasion path of water / sound between the panel and the seal member can be expected, so that the sealing performance can be improved.

  According to the second aspect of the present invention, since the seal member is fitted in the seal insertion groove in a compressed state, the seal member can be easily attached to the front surface of the connector so as not to drop off without using an adhesive. Accordingly, it is possible to eliminate all of the poor mounting accuracy, the poor mounting workability, the poor recyclability at the time of disassembly, and the like when the adhesive is used for mounting. Moreover, since it fits into the seal insertion groove in a compressed state, the density of the entire seal member can be increased, and the seal performance can be improved accordingly.

  According to the invention of claim 3, since the seal member is prevented from coming off by the locking claw, it is possible to prevent the seal member from falling off during transport and the like, and it becomes easy to manage the parts.

  According to the fourth aspect of the present invention, since the compression force can be further applied to the protruding portion, the sealing performance is improved.

  According to the invention of claim 5, since the seal member can be locally compressed by the annular convex portion, the sealing performance can be enhanced by the crushed portion having a high compression rate. Furthermore, by providing the annular convex portion, even if a gap is generated in the portion where the seal member is attached to the front surface of the connector, the intrusion path of water or sound can be blocked. Further, since only a part of the seal member is highly compressed, the repulsive force by the seal member can be reduced as compared with the case where the whole is uniformly highly compressed. Therefore, even if the pressing force between the connector and the panel is not increased, the sealing property can be improved and the mounting property of the connector to the panel is not deteriorated. In addition, since the convex portion is embedded in the seal member, a labyrinth effect can be expected in which the length of the invasion path of water / sound between the panel and the seal member can be expected, so that the sealing performance can be improved.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  As shown in FIGS. 9 and 10, the seal structure of this embodiment is disposed on both sides (vehicle compartment R side and engine room E side) of a vehicle body panel (simply referred to as a panel) P, and is formed on the panel P. An annular seal member 10 is provided on the front surface of the male connector 1 on the vehicle compartment R side of the pair of male and female connectors 1 and 40 that are fitted to each other through the opening Pa, and the seal member 10 is pressed against the panel P. Thus, the gap between the connectors 1 and 40 and the panel P is sealed.

  As shown in FIGS. 3 and 5, the male connector 1 is configured by mounting the panel seal unit 25 on the front portion of the connector main body 30. As shown in FIGS. 1 and 3, the panel seal unit 25 has the seal member 10 fitted in a seal insertion groove 21 provided on the front surface of the flange portion 20A of the panel seal unit main body 20 made of a hard resin molded body. It is composed. The seal member 10 is fitted in the seal insertion groove 21 by forming a string-like elastic seal material 10M having a rectangular cross section into an annular body that is bent inward.

  In this case, as shown in FIGS. 2 and 4, the width of the seal member 10 is formed larger than the width of the seal insertion groove 21, and the seal member 10 is forced into the seal insertion groove 21 as indicated by an arrow A. Thus, the seal member 10 is fitted in a compressed state by receiving a lateral pressure indicated by an arrow B1 from both side walls 21a and 21b on the inner and outer circumferences of the seal insertion groove 21. The heights of the inner and outer side walls 21a and 21b of the seal insertion groove 21 are equal to a height that does not allow the seal member 10 fitted in the compressed state to protrude.

  On the other hand, as shown in FIG. 6, an annular rib Pb erected toward the front surface of the male connector 1 on the vehicle compartment R side is projected from the periphery of the substantially rectangular opening Pa of the panel P.

  As described above, when the rib Pb is bitten into the seal member 10, the degree of compression of the seal member 10 at the bited portion is locally increased, so that the adhesion between the panel P and the seal member 10 at that portion can be enhanced. . Moreover, since the outer peripheral part of the seal member 10 is restrained by the groove inner wall by fitting the seal member 10 in the seal insertion groove 21, the overall compression degree of the seal member 10 is increased when the rib Pb is bitten. Accordingly, the contact pressure between the seal member 10 and the panel P and the panel seal unit main body 20 can be increased accordingly. Accordingly, even if the pressing force between the male connector 1 and the panel P is not particularly increased, the sealing property can be improved, and the mounting property of the male connector 1 to the panel P is not deteriorated. In addition, since the rib Pb bites into the seal member 10, a labyrinth effect can be expected to increase the length of the water / sound intrusion path between the panel P and the seal member 10, which also improves the sealing performance. Can be planned.

  Further, since the seal member 10 is fitted in the seal insertion groove 21 in a compressed state, the front surface of the male connector 1 (the flange portion 20A of the panel seal unit main body 20) is used so that the seal member 10 is not dropped without using an adhesive. Can be easily attached to the front of the camera. Accordingly, it is possible to eliminate all of the poor mounting accuracy, the poor mounting workability, the poor recyclability at the time of disassembly, and the like when the adhesive is used for mounting.

As shown in FIG. 28, on the contrary, it protrudes toward the plate surface of the panel P on the seal mounting surface (front surface) 521 of the flange portion 20A of the panel seal unit main body 520 constituting the panel seal unit 525 of the male connector 1B. By forming the annular convex portion 522 to be attached, and sticking the seal member 10 to the seal mounting surface 521 so as to cover the annular convex portion 522, the seal member 10 is pressed against the plate surface of the panel P. The seal member 10 is compressed locally at a position where the convex portion 522 is present, rather than at other positions. 27 and 28, reference numerals 521a and 521b denote stepped portions and ribs that define the seal mounting surface 21.

  As an example of the convex part 522, there exists a thing as shown in FIGS. (A) of each figure is sectional drawing, (b) is sectional drawing which shows the state which affixed the sealing member on the flange part of the panel seal unit main body, and was made to press-contact with the board surface of a panel.
