Description

A floating sealing rubber pad and a connector installed with the sealing rubber pad

technical field

The utility model relates to a connector, and also relates to a sealing rubber pad used on the connector.

Background technique

In some connectors used for fixing through walls, a mounting plate is set outside the housing of the connector. The mounting plate is provided with mounting holes for fixing to the wall. The mounting plate is connected with the connector according to actual needs There is a certain gap between the housings, so that the connector can be offset by a certain distance in the axial or radial direction in the mounting plate, and the overall state is in a floating state. When the connector is installed outdoors, due to the harsh outdoor conditions, when it rains, rainwater easily enters into the connector through the gap between the mounting plate and the connector housing, thereby destroying the insulation of the connector. Therefore, it is necessary to provide a sealing device between the connector housing and the mounting plate. Existing connectors are usually sealed with sealing rubber pads or O-rings, but when used in this connector, if the sealing rubber pads are used, since the connector floats in the mounting plate, rainwater is easy to flow from the inside of the sealing rubber pads. Infiltration between the ring and the connector housing, the sealing effect is not good; if the O-ring seal is used, the O-ring must be installed in the gap between the mounting plate and the connector to have a sealing effect, but this will inevitably limit the connector Float in mounting plate. Therefore the existing sealing method is not suitable for this connector.

An annular groove is axially provided on the panel of the installation plate facing the wall, and an annular flange matching the annular groove protrudes from the outer edge of the sealing rubber pad.

The inner wall of the annular rubber sleeve is provided with more than one ring of annular protrusions for sealing contact with the connector housing.

Another object of the present utility model is to provide a floating sealing rubber pad for the above-mentioned connector.

In order to achieve this purpose, the technical solution adopted by the utility model is: a floating sealing rubber pad, including a sealing rubber pad used for sealing between the mounting plate and the wall surface, and the inner ring of the sealing rubber pad is provided with a The annular rubber sleeve is sealed and fitted on the outer circle of the housing. The annular rubber sleeve has a frusto-conical structure as a whole, and the diameter of the small end of the annular rubber sleeve is smaller than the diameter of the connector housing.

The integral ring of the sealing rubber pad is arranged on the outer edge of the big end of the annular rubber sleeve.

An annular flange for matching with an annular groove on the mounting plate protrudes from the outer edge of the sealing rubber pad.

The inner wall of the annular rubber sleeve is provided with more than one ring of annular protrusions for sealing contact with the connector housing.

The connector of the utility model has a simple structure, and its truncated conical annular rubber sleeve is deformed and fitted on the outer circle of the connector housing to form a stable seal with the connector housing. When the connector is installed on the wall through the mounting plate After being installed, the sealing rubber pad is pressed and pressed by the mounting plate. When the connector floats back and forth, left and right in the mounting plate, the truncated conical annular rubber sleeve can always maintain the seal between the connector shell and play a role The function of waterproof and moisture-proof ensures the stable connection of the connector.

Detailed ways

As shown in Fig. 1 and Fig. 2, the connector of the present invention includes a housing 2, an insulator 1 is arranged in the housing 2, an O-shaped sealing ring 4 is arranged between one end of the housing 2 and the insulator 1, and an O-ring 4 is arranged between one end of the housing 2 and the insulator 1. The other end of the body 2 is connected with an accessory 8 through a mounting nut 7 . A mounting plate 6 for connecting with the wall is set on the outside of the housing 2. The inner ring of the mounting plate 6 is in clearance fit with the outer circle of the housing 2, so that the mounting plate 6 is in a floating state on the housing 2. The shell 2 is also pierced with a ripple spring 5 . Since the gap between the mounting plate 6 and the housing 2 is large, in order to prevent water leakage when the connector is installed and used outdoors, a floating sealing rubber pad 3 is also provided between the housing 2 and the mounting plate 6 . The floating sealing rubber pad 3 includes a sealing rubber pad 32 for sealing between the mounting plate 6 and the wall surface. The inner ring of the sealing rubber pad 31 is provided with an annular rubber sleeve 31 of an integral structure along the axial direction of the connector. The sleeve 31 has a frusto-conical structure as a whole, the diameter of its large end is equivalent to the diameter of the connector housing 2 , and the diameter of its small end is smaller than that of the connector housing 2 . An annular flange 33 protrudes from the outer edge of the sealing rubber pad 32 , and an axial annular groove is defined corresponding to the annular flange 33 on the panel of the mounting plate 6 facing the wall. On the inner wall of the annular rubber sleeve 31 there is also an annular protrusion 34 for sealingly fitting with the connector housing 2 .

During installation, the sealing rubber pad 32 on the floating sealing rubber sleeve 3 is compressed by the mounting plate 6 and the wall surface, and the annular flange 33 on the sealing rubber pad 32 is pressed into the axial ring groove on the mounting plate 6 to increase the sealing. effect, and at the same time prevent the sealing rubber pad 32 from detaching from the pressing surface of the mounting plate 6 when the connector is floating, so as to ensure the sealing of the connector. Since the annular rubber sleeve 31 is a tapered sleeve structure, it will be elastically deformed and tightened on the connector housing during installation, and the annular protrusion 34 on the inner wall of the annular rubber sleeve 31 is in close contact with the outer circle of the connector housing 2 to form a Sealing, so that the annular rubber ring 32 makes the mounting plate 6 float on the housing 2 no matter whether it is floating up, down, front, back, left or right, the floating sealing rubber pad 3 can always be kept between the connector housing 2 The airtight seal plays a role in preventing rain and moisture.
