Endoscope connector using waterproof cap
A connector for an endoscope mounting a waterproof cap on a connection port for a connector having electrical connection member disposed therein in which an O ring providing waterproof characteristics by making close contact with an inner periphery of the connection port and a second seal member providing waterproof characteristics by making close contact with a front face of a rotating ring used for fixing a connector receiving part disposed on an outer periphery of the connection port are provided. The second seal member has a size which does not exceed the outer periphery of the rotating ring due to being formed in a bell shape having a flared section. A third seal member (O ring, V ring or oil seal) maintaining a watertight condition is provided between the rear end of the rotating ring and the rear member of the main body of the connector.
1. A connector for an endoscope comprising:
a connection port for a connector having an electrical connection member disposed therein;
an outer member disposed on an outer periphery of the connection port; and
a waterproof cap mounted on the connection port of the connector; wherein
the waterproof cap comprises a first seal member providing waterproof characteristics by making close contact with an inner peripheral face of the connection port and a second seal member providing waterproof characteristics by making close contact with the front face of the outer member, and
the outer member is a rotating ring rotatably disposed on an outer peripheral side of the connection port and rotated to fix the connector into a connector receiving part, and a third seal member maintaining watertight conditions is provided between a rear end of the rotating ring and the connector main body, and the second seal member of the waterproof cap is disposed in close contact with the front face of the rotating ring.
2. The connector for an endoscope according to claim 1 , wherein the third seal member comprises an O ring, a V ring or an oil seal.
3. A connector for an endoscope comprising:
a connection port for a connector having electrical connection member disposed therein;
an outer member disposed on an outer periphery of the connection port; and
a waterproof cap mounted on the connection port of the connector; wherein
the waterproof cap comprises a first seal member providing waterproof characteristics by making close contact with an inner peripheral face of the connection port and a second seal member comprising a seal body of a size not exceeding the outer periphery of the outer member and providing waterproof characteristics by making close contact with the front face of the outer member, and
the outer member is a rotating ring rotatably disposed on an outer side of the connection port and rotated to fix the connector into a connector receiving part, and a third seal member maintaining watertight conditions is provided between a rear end of the rotating ring and the connector main body, and the second seal member of the waterproof cap is disposed in close contact with the rotating ring.
4. The connector for an endoscope according to claim 3 , wherein the second seal member makes close contact with the inner peripheral face of the outer member.
5. The connector for an endoscope according to claim 3 , wherein the third seal member comprises an O ring, a V ring or an oil seal.
6. A connector for an endoscope comprising:
a connection port for a connector having electrical connection member disposed therein;
a waterproof cap mounted on the connection port of the connector;
a waterproof seal member for the connector comprising resilient rubber;
a first member and a second member formed from a synthetic resin material, the first member and second member are constituted by at least two members forming the waterproof cap by connection via press fitting, and forming a space into which a base of the seal member is sandwiched during press fitting and connection;
a first seal member of the waterproof cap providing waterproof characteristics by making close contact with an inner peripheral face of the connection port; and
a second seal member of the waterproof cap providing waterproof characteristics by making close contact with an outer member disposed on an outer side of the connection port, wherein
the waterproof seal member is mounted on the waterproof cap by sandwiching the seal member between the first member and second member and press fitting and connection of the first member and second member,
the outer member is a rotating ring rotatably disposed on an outer side of the connection port and rotated to fix the connector into a connector receiving part, and
a third seal member maintaining watertight conditions is provided between a rear end of the rotating ring and the connector main body, and the second seal member of the waterproof cap is disposed in close contact with the rotating ring.
