DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows the connector A before connection. The connector A is mainly composed of a first housing 10 and a second housing 20. First, the first housing 10 will be described. The first housing 10 includes a first connection passage 11 penetrating the first housing 10.
A holding portion 12 protruding inward is formed in the first connection passage 11, and a male connector 13 is fixed to a part of the holding portion 12. A gap 12a exists between the male connector 13 and the holding portion 12, and the first connection passage 11 communicates with each other even when the male connector 13 is fixed. The male connector 13 includes an electric wire 14 extending from one end portion (non-connection end portion) 17. The convex portion 16 is provided on the first housing 10.
Is formed, and the convex portion 16 is adapted to engage with a locking portion 26 formed in the second housing 20 described later. The first housing 10 is provided with another first connection passage (not shown) in addition to the first connection passage 11.
Similarly, a male connector (not shown) to which the electric wire 15 is connected is arranged here.

Next, the second housing 20 will be described. The second housing 20 is also the first housing 10
Similarly to the above, a second connection passage 21 penetrating the second housing 20 is formed, and like the first connection passage 11, the female connector 23 is fixed to the holding portion 22 in the second connection passage 21. The difference from the first housing 10 is the second connection passage 2
1 is a point formed inside the tubular portion 20a of the second housing 20, and the outer diameter of the tubular portion 20a is equal to that of the first connection passage 11
Is equal to the inner diameter of. That is, the tubular portion 20a is the first
The first housing 10 and the second housing 20 are connected by being inserted into the connection passage 11. In addition, the second housing 20 has a hook-shaped engaging portion 2
6 is formed, and the engaging portion 26 engages with the convex portion 16 of the first housing 10 so that the joined first housing 10 and second housing 20 are locked so as not to come off easily. It has become so. The second housing 20 is provided with another second connection passage (not shown) in addition to the second connection passage 21, and here also a female connector (not shown) to which the electric wire 25 is similarly connected. ) Is provided.

Here, in the first embodiment, the first housing 1
The first connecting passage 11 of 0 is filled with grease 19.
The grease 19 has a property that the oil film disappears when it is pressurized. Therefore, when the tubular portion 20a is inserted into the first connection passage 11 so as to connect the first housing 10 and the second housing 20, that is, the male connector 13 and the female connector 23 are connected, as shown in FIG. As described above, the grease 19 in the first connection passage 11 also moves into the second connection passage 21, and the male connector 13 and the female connector 23 to be connected are covered with the grease 19 to be shielded from the outside air. Therefore, the male connector 1
3 and the female connector 23 are waterproofed. Further, since the grease 19 is not solidified by a viscous insulating member, the connector once connected can be separated again, and even if it is connected again, it can be waterproof unless grease is removed. Further, the grease 19 sandwiched between the male connector 13 and the female connector 23 loses the oil film due to the pressure from both connectors, so that the male connector 13 and the female connector 23 are not in electrical contact with each other. Reserved.

Next, the second to eighth embodiments will be described. In the embodiments described below, the structure of parts other than the grease injection portion is the same as that of the first embodiment. I will omit it.

First, in the second embodiment, as shown in FIG. 3, not only the first connecting passage 11 but also the second housing 20
The connection passage 21 is also filled with grease 19. In this way, when the first housing 10 and the second housing 20 are connected to each other, the grease can be filled in the entire passage as shown in FIG. In the second embodiment, unlike the first embodiment, the grease 19 protrudes from the end of each passage by the amount at which the first connection passage 11 and the second connection passage 21 intersect, but the grease 19 is filled without gaps in each passage. It is possible to ensure the waterproof effect.

In the third embodiment, as shown in FIG. 4, grease 19 is injected only in the tip portion of the first connecting passage 11,
The first housing 10 and the second housing 20 are connected.
Then, after connection, grease 19 is injected from the passages at both ends to close the passages (FIG. 5). In this embodiment, grease 1 is also applied to the end portions b of the first connection passage 11 and the second connection passage 21 after connection.
9 was injected. In this embodiment, since the grease 19 covers the connecting portion a of the male connector 13 and the female connector 23 as the center, the grease can be waterproofed with a small amount of grease, and the passages after the connection can be sealed by the grease. It is possible to prevent water from collecting in.

In the fourth embodiment, as shown in FIG. 6, only the first connecting passage 11 is filled with grease 19, and the non-connecting end portions 17 and 27 of the first connecting passage 11 and the second connecting passage 21 are filled.
Is sealed with silicon 18, 28, which is a sealing member,
The housing 10 and the second housing 20 were connected (Fig. 7). In this embodiment, since both ends of the passage are sealed with silicon, the grease 19 does not come into contact with the outside air. Therefore, moisture does not permeate from the non-connecting end portions 17 and 27 over time, and long-term waterproofing becomes possible.
5, 24 and 25 are more firmly fixed to each housing.

Note that, as shown in the fifth embodiment of FIG. 8, grease 19 may be preliminarily injected into both the first connection passage 11 and the second connection passage 21 of each housing.

The sixth embodiment (FIGS. 9 and 10) is a connector in which grease 19 is injected only into the tip portion of the first connecting passage 11, and the seventh embodiment (FIG. 11) is the first connecting passage 11 and the connector. The connector in which the grease 19 is injected only into the tip portion of the 2 connection passage 21, the 8th embodiment (FIG. 12) is the first connection passage 11
1 and the connector in which the grease 19 is injected into both ends of the second connection passage 21. In this way, if grease is injected into at least one of the end portions of the passages, the grease 19 covers the connecting portion a of the male connector 13 and the female connector 23 as a center, and therefore, waterproofing should be performed with a small amount of grease. You can Further, even if there is a portion where grease is not injected in each passage, the non-connecting end portions 17 and 27 are made of silicon 18 and 2.
Since it is sealed with 8, it prevents water from penetrating into the passage portion where grease 19 is not injected.

In this embodiment, the connector for connecting two independent housings has been described. However, for the connector in which one housing is arranged on the circuit board, grease can be injected as in the above-described embodiments. By
The same effect can be achieved.

[0018]

According to the present invention, the male connector and the female connector are protected while ensuring the electrical connection between both from the humidity of the outside air, and even in a high humidity state, there are problems such as poor insulation, short circuit, and electric leakage. Does not occur. Further, the male connector and the female connector are waterproof, but since the connecting portion is not solidified, they can be freely attached and detached. Furthermore, by sealing the non-connection ends of the first connection passage and the second connection passage with a sealing member, moisture does not permeate from the non-connection ends of the housings over time, and long-term waterproofing is achieved. It will be possible.
