Conventionally, waterproof connectors are shown in Figures 6 and 7.
As shown in the figure, there is a receptacle 3 attached to a panel 1 and a plug 5 that is removably fitted into the receptacle 3.

The receptacle 3 includes an insulator 7 in which a large groove 9 is formed on one side (front side). The insulator 7 has a plurality of conductive contacts 11 such as pin contacts so as to correspond to the groove 9.
is retained. A cable 13 is pulled out from a surface (back surface) opposite to one surface of the insulator 7. The cable 13 is electrically connected to the contact 11 inside the insulator 7.

Further, the front surface of the insulator 7 is provided with a plurality of locking portions 15 integrally formed of the same material as the insulator 7. These locking portions 15 fix the receptacle 3 to the panel 1 by engaging with the edges of the holes 16 in the panel 1.
Note that a waterproof sealing member 17 such as a rubber material is interposed between the front surface of the receptacle 3 and the panel 1.

On the other hand, the plug 5 includes a mating insulator 19 and a plurality of conductive mating contacts 21, such as socket contacts, held inside the mating insulator 19, as also shown in FIG. A ring-shaped sealing member 22 is provided on the outer peripheral surface of the mating insulator 19 .

On one side (front) of the opponent insulator 19,
A through hole 23 is formed to receive the contact 11 of the receptacle 3. On the opposite surface (back side) of the mating insulator 19, a mating contact 21 is provided.
A waterproof plug 27, such as an integrated grommet, is fitted to hold the cable 25 connected to the mating insulator 19 and to waterproof the space between the inside and outside of the mating insulator 19.

In such a waterproof connector, panel 1
When the mating insulator 19 is inserted into the groove 9 of the insulator 7 attached to the holder, an electrical connection between the contact 11 and the mating contact 21 is obtained. At the same time, waterproofness is achieved by the seal member 17 interposed between the insulator 7 and the panel 1, the seal member 22 of the mating insulator 19, and the waterproof plug 27.

[Problem that the invention attempts to solve]

However, in the conventional waterproof connector, the shape of the mating contacts 21 is limited by the waterproof plug 27, so the mutual spacing between the mating contacts 21 cannot be narrowed, the waterproof structure becomes complicated, and the high-density plug 5 is required. The problem is that you can't get it.

Furthermore, as shown in FIG. 8, the assembly is performed by attaching the waterproof plug 27 to the cable 25 and connecting the mating contact 21 to the cable 25, and then inserting the mating contact 21 into the mating insulator 19. There is a problem in that it is difficult to feel that the mating contact 21 is completely attached to the interior of the mating insulator 19.

Therefore, it is an object of the present invention to provide a waterproof connector that has a simple waterproof structure and can have high contact density.

[Means for solving problems]

According to the present invention, a connector to be attached to a panel includes a connector main body having flanges facing the panel at a distance and connected to an end of a cable, and a connector main body and a vicinity of the end of the cable. and a locking hood that covers the outside of the boot and is locked to the panel, thereby pressing the flange of the connector body toward the panel; A boot-pressed waterproof connector is obtained, wherein the boot has a portion that is pressed between the flange and the panel.

〔Example〕

FIGS. 1 to 3 show an embodiment of the boot press type waterproof connector of the present invention.

The illustrated boot-pressing waterproof connector has a receptacle 37 mounted on a horizontal panel 35.
Plug (connector body) that is removably mated to
It has 39.

The receptacle 37 includes an insulator 43 having a large groove 41 formed in its upper surface, and a plurality of conductive contacts 45 such as pin contacts held in the insulator 43 so as to correspond to the grooves 41. The contact 45 extends from the bottom of the groove 41 toward the opening.
The cable 4 is connected from the bottom of this insulator 43.
7 is drawn out. The cable 47 is connected to the contact 45 inside the insulator 43.

Further, the upper surface of the insulator 43 is provided with a plurality of locking portions 49 integrally formed of the same material as the insulator 43. These locking parts 49 are inserted into the holes 36 of the panel 35,
The tip of the locking piece 49 is engaged with the upper surface of the panel 35, thereby fixing the receptacle 37 to the panel 35. Note that a waterproof sealing member 51 such as a rubber gasket is sandwiched between the upper surface of the receptacle 37 and the panel 35 in a compressed state.

Further, in the wall around the groove 41 of the insulator 43, locking piece grooves 59 are formed in one-to-one correspondence with the plurality of locking piece holes 57 formed in the panel 35 as shown in FIG. There is.

On the other hand, the plug 39 is connected to the mating insulator 61
and a plurality of conductive mating contacts (not shown) such as socket contacts held by the mating insulator 61. The mating insulator 61 is inserted into the groove 41 on one side of the insulator 43 of the receptacle 37 described above. A plurality of cables 63 connected to the mating contacts are drawn out from the upper surface of the mating insulator 61. A flange portion 65 is formed on the outer peripheral surface of this mating insulator 61.

This waterproof connector further includes a boot 68 of a predetermined length formed of a rubber material into a cylindrical shape as shown in FIG. The boot 68 tightly covers the plurality of cables 63 from the outside. A groove 72 is previously formed on the inner peripheral surface of the opening 70 at one end of the boot 68. By fitting this groove portion 72 into the flange portion 65, the boot 68 is connected to the mating insulator 61. A cable 63 is led out from the other end of the boot 68.

The opening 70 at one end of the boot 68 on the surface that comes into close contact with the panel 35 is smaller than the outer shape of the flange 65 of the mating insulator 61. Therefore,
While expanding the opening 70 of the boot 68, the groove 72 is fitted into the flange 65 of the mating insulator 61. As a result, the boot 68 comes into close contact with the front surface of the outer periphery of the flange portion 65.

The waterproof connector further includes a lock hood 53, also shown in FIG. This lock hood 53 covers the upper surface of one end portion of the boot 68.
An opening 74 is formed in the lock hood 53 to allow the boot 68 to be taken out. Furthermore, a plurality of hood locking pieces 55 are formed on the end surface forming the large opening 76. The hood locking piece 55 is inserted into a locking piece hole 57 formed in the panel 35 and engaged with the lower surface of the panel 35.

Next, connection using this waterproof connector will be explained. First, the receptacle 37 is fixed to the panel 35. Then, the plug 39 is fitted into the receptacle 37. At this time, the plug 39 and the cable 63 drawn out from it are provided with a boot 68 in the above-described structure in advance. After fitting the plug 39 into the receptacle 37, the lock hood 53 is set. and opponent insulator 6
While compressing the boot 68 between the flange portion 65 of the lock hood 53 and the panel 35, the hood locking piece 55 of the lock hood 53 is inserted into the locking hole 57 of the panel 35. As a result, the hood locking piece 55 is locked to the panel by its spring restoring force. Therefore plug 3
9 is the panel 3 connected to the receptacle 37.
It is fixed at 5.

Note that the boot 68 is desirably designed to be long enough to prevent water from entering. Although the plug 39 has been described above as a connector main body, the same can be applied to the receptacle 37. Furthermore, the present invention can be implemented in the same manner even if the connector main body is of another type.

[Effect of idea]

As explained above using the embodiments, according to the present invention, since the connector body is covered by the boot,
A simple waterproof boot press type connector is obtained. In addition, the entire waterproof function can be obtained by simply pressing and locking the lock hood, so the connection work is easy. Furthermore, since the connector main body does not require a waterproof plug for the cable portion, it is possible to design the contact spacing to be small, and therefore it is possible to provide a boot-pressing type waterproof connector that can be easily increased in density.
