CN-122000728-A - Connector with a plurality of connectors

Abstract

The invention provides a connector capable of improving waterproofness. The connector includes a connector housing having a tubular connector body portion capable of fitting into a mounting hole of a panel in a1 st direction and a connector flange portion protruding radially outward from an outer periphery of the connector body portion and fixed to the panel, and a seal having a tubular portion and an annular flange portion, the tubular portion being disposed between the connector body portion and the mounting hole so as to cover an outer peripheral surface of the connector body portion, and the flange portion being disposed between the connector body portion and the panel so as to cover an end surface of the connector flange portion in the 1 st direction. The flange portion has a1 st lip portion that protrudes in the 1 st direction to press and contact the panel in a state where the connector housing is fixed to the panel, and a2 nd lip portion that protrudes in the 1 st opposite direction to press and contact the connector flange portion in a state where the connector housing is fixed to the panel.

Claims (5)

1. 1. A connector includes a connector housing and a seal, The connector housing has a cylindrical connector body portion capable of fitting with a mounting hole of a mounting object along a1 st direction, and a connector flange portion protruding radially outward from an outer periphery of the connector body portion, the connector housing being fixed to the mounting object; The seal includes a cylindrical portion that is disposed between the outer peripheral surface of the connector body portion and the mounting hole so as to cover the outer peripheral surface, and an annular flange portion that is disposed between the end surface of the connector flange portion in the 1 st direction and the mounting object so as to cover the end surface; The flange portion has a 1 st lip portion that protrudes in the 1 st direction so as to press-contact the mounting object in a state where the connector housing is fixed to the mounting object, and a2 nd lip portion that protrudes in a 1 st reverse direction that is a reverse direction of the 1 st direction so as to press-contact the connector flange portion in a state where the connector housing is fixed to the mounting object.
2. 2. The connector of claim 1, wherein, The 1 st lip portion and the 2 nd lip portion are formed of arc portions formed at the outer edge of the flange portion and having a circular arc shape with a cross-sectional shape of more than 180 ° cut off in the radial direction.
3. 3. The connector of claim 1, wherein, The cylindrical portion and the flange portion are connected by an inclined wall thickness portion, and the outer diameter is larger and the wall thickness is thicker as the inclined wall thickness portion is oriented in the 1 st reverse direction.
4. 4. The connector of claim 1, wherein, The flange portion has a 1 st recess formed radially inward of the 1 st lip portion and configured not to contact the mounting object in a state where the 1 st lip portion is press-contacted with the mounting object, and a2 nd recess formed radially inward of the 2 nd lip portion and configured not to contact the connector flange portion in a state where the 2 nd lip portion is press-contacted with the connector flange portion.
5. 5. The connector of claim 1, wherein, The connector housing has a fixing portion protruding radially outward from an outer periphery of the connector flange portion and having one fixing hole, and is fixed to the mounting object by a bolt penetrating the fixing hole.

Description

Connector with a plurality of connectors Technical Field The present invention relates to a connector. Background Conventionally, as a connector, there is a connector including a connector housing and a seal attached to the connector housing, the connector housing including a cylindrical connector body portion and a connector flange portion protruding radially outward from an outer periphery of the connector body portion (for example, refer to patent document 1). The seal has a cylindrical portion disposed between the outer periphery of the connector body portion and the mounting hole of the mounting object, and an annular flange portion disposed between the end face of the connector flange portion and the mounting object, covering the end face. The flange portion has a lip portion protruding toward the mounting object, and the lip portion is pressed against the mounting object in a state where the connector housing is fixed to the mounting object. In this structure, the lip portion is partially pressed against the mounting object, so that the waterproof performance of the portion is improved. Further, since the flange portion having the lip portion is coupled to the tube portion covering the outer peripheral surface of the connector main body portion, the radial position of the lip portion is stable. Therefore, the waterproof property can be made high and stable. Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2022-89567 Disclosure of Invention Problems to be solved by the invention However, since the surface of the flange portion of the seal of the connector facing the end surface of the connector flange portion is shaped along the end surface of the connector flange portion, the force of pressing contact with the end surface of the connector flange portion is not concentrated and dispersed. As a result, the waterproof property between the flange portion and the connector flange portion may be inferior to that between the lip portion and the mounting object. The invention aims to provide a connector capable of improving waterproofness. Means for solving the problems The connector of the present invention comprises a connector housing having a tubular connector body portion capable of fitting with a mounting hole of a mounting object along a 1 st direction and a connector flange portion protruding radially outward from an outer periphery of the connector body portion, the connector housing being fixed to the mounting object, and a seal having a tubular portion and an annular flange portion, the tubular portion being disposed between the outer periphery and the mounting hole so as to cover the outer periphery of the connector body portion, the flange portion being disposed between the mounting object and the 1 st direction end face of the connector flange portion so as to cover the end face, the flange portion having a 1 st lip portion and a2 nd lip portion, the 1 st lip portion protruding in the 1 st direction so as to press-contact the mounting object in a state in which the connector housing is fixed to the mounting object, and the 2 nd lip portion protruding in a 1 st direction which is a direction opposite to the 1 st direction so as to press-contact the connector flange in a state in which the connector housing is fixed to the mounting object. Effects of the invention According to the connector of the present invention, the waterproof property can be improved. Drawings Fig. 1 is a perspective view of a connector in an embodiment.
