Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof connector fixed to a panel board for use.

[0002]

2. Description of the Related Art Conventionally, for example, in a method of mounting a connector mounted on a door panel of an automobile, a rubber grommet 2 is mounted on a door panel plate 1 as shown in FIG. While inserting it, the electric wires 3 are connected by the connector 4.

Alternatively, as shown in FIG. 5, the waterproof connector 4
After combining a pair of housings 4a, 4b of
It is attached to the panel board 1 through the packing 5.

[0004]

Therefore, in the former case, the connector 4 is attached to the door panel 1 in a suspended state, and in the latter case, the connector 4 must be assembled and then attached. Has the above drawbacks.

An object of the present invention is to mount one connector housing on a panel board and to fit the other connector housing thereto with bolts so that the connector housings can be connected together and a waterproof function can be exerted. It is to provide a waterproof connector to obtain.

[0006]

In order to achieve the above object, a waterproof connector according to the present invention has a first connector housing fixed to a panel board, and a second connector housing fitted to the first connector housing. In a connector that holds the mated state, the first connector housing is fixed to the panel plate via a ring-shaped first waterproof sealing material,
A substantially bowl-shaped second waterproof sealing material that covers the rear portion of the second connector housing is attached, the connector housings are fitted together, and the bolts are tightened to deepen the fitting of the connector housings. In addition, the opening edge portion of the second waterproof sealing material is brought into close contact with the panel plate.

[0007]

In the waterproof connector having the above-mentioned structure, the connector housings are fixed to each other by bolts, and at the same time, the waterproof function is provided.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in FIGS. FIG. 1 shows a female housing 1 of a connector.
1 is a sectional view of the male housing 12, and FIG. 2 is a sectional view of the male housing 12. A plurality of flat blade-shaped connection terminals 13 are built in a female housing 11 made of synthetic resin, and wirings (not shown) are drawn out to the outside via a waterproof sealing material 14. Further, a flange 15 is provided around the female housing 11, and the female housing 1 is further provided.
An elastic fixing spring 17 for fixing the female housing 11 to the hole portion 16 a of the panel plate 16 is provided at the front end of 1.

A ring-shaped waterproof packing 18 made of, for example, synthetic rubber is provided between the flange 15 and the fixed spring 17.
When the waterproof packing 18 is pressed into the hole 16a of the panel plate 16 while compressing the fixed spring 17 against its springiness, the tip of the fixed spring 17 is restored after passing through the hole 16a. At the same time as engaging the portion 16a, the waterproof packing 18 provides a seal between the panel plate 16 and the female housing 11. Further, a bolt hole 19 for fixing the male housing 12 is provided at the center of the female housing 11.

On the other hand, a male housing 1 made of synthetic resin
2 includes a plurality of receiving terminals 21 that are fitted into the flat blade terminals 13 of the female housing 11, respectively. A ring-shaped mounting member 22 made of a synthetic resin or a separate member is fitted around the male housing 12, and the mounting member 22 has a substantially bowl shape so as to cover the entire rear portion of the male housing 12. Shaped waterproof cover 23 made of synthetic rubber, for example
Is attached. The electric wire connected to the receiving terminal 21 is
It is pulled out to the outside through an insertion hole provided in a part of the waterproof cover 23 in consideration of waterproofing. A bolt 24 is inserted from the rear end of the waterproof cover 23 into the male housing 12 through a seal portion 23a, and the tip of the bolt 24 is screwed into the bolt hole 19 of the female housing 11. It has become. The opening end 23b of the waterproof cover 23 has a flexible cross-sectional shape so as to exert a waterproof effect when pressed against the panel plate 16.

Therefore, as shown in FIG. 3, the male housing 12 is fitted into the female housing 11 already attached to the panel plate 16, and the bolt 24 is further inserted into the bolt hole 19 of the female housing 11. When screwed and tightened,
The housings 11 and 12 are fitted deeply and securely,
The terminals 13 and 21 are electrically connected to each other. at the same time,
The waterproof cover 23 is pressed against the panel plate 16 side by the mounting member 22, and the opening edge portion 23b thereof comes into close contact with the panel plate 16.

Therefore, the female housing 11 and the male housing 12 are hermetically sealed by using the panel plate 16, and the water from the outside is covered by the waterproof packing 18 and the waterproof cover 23, and the electric wires provided in the respective housings 11, 12. The waterproof sealing material for pulling out eliminates the possibility of entering the inside of the housings 11, 12.

[0013]

As described above, the waterproof connector according to the present invention can be fixed to the panel board, the connector housings can be easily attached / detached by bolts, and further, the intrusion of water into the inside of the housing can be prevented. Can be prevented.
