Claims
- 1. A rubber plug for use in a waterproof connector, the rubber plug comprising:
- a hole and a wire passed through the hole, the rubber plug and the wire being insertable into an open end of a tubular portion of the waterproof connector to form a seal between a wall of the tubular portion and the wire; and
- an end plug positioned at a side of the waterproof connector at which the open end is disposed, the end plug closing the open end and having a convex shaped outer surface so as to cover the open end and direct water away from the wire and the hole.
- 2. The rubber plug of claim 1, wherein the outer surface extends outwardly from the hole to a peripheral lip portion overlying and contacting the wall of the tubular portion, the entire outer surface being convex shaped.
- 3. A waterproof seal for use in an electrical connector having a tubular passage for receiving a wire terminal, the waterproof seal comprising:
- a main plug portion that forms a seal between the wire terminal and the tubular passage, the main plug portion including a rubber body having a pair of flange-like collars sealably engageable with an inner wall surface of the tubular passage; and
- an end plug connected to the main plug portion and covering an end of the tubular passage, the end plug including a rubber body having a lip portion extending outward beyond the inner wall surface of the tubular passage, the end plug having a convex shaped outer surface and an inner peripheral surface which abuts against an end of the tubular passage.
- 4. The waterproof seal of claim 3, wherein the lip portion imparts a constant biasing force against the end of the tubular passage, and the end of the tubular passage imparts an opposing force against the biasing force so as to maintain a tight seal between the electrical connector and the lip portion.
- 5. The waterproof seal of claim 3, wherein the main plug and the end plug define an axial hole through the waterproof seal which receives the wire terminal, the outer surface extends outwardly from the hole and the entire outer surface being convex shaped.
- 6. A rubber plug for use in a waterproof connector, comprising:
- a hole and a wire extending through the hole, the rubber plug and the wire being together insertable into a tubular portion of the waterproof connector to form a seal between a wall of the tubular portion and the wire; and
- an end plug formed at a side of the connector at which an open end of the tubular portion is disposed, the end plug having a convex shaped outer surface directing fluid on the end plug away from the wire and the hole and closing the open end.
- 7. The rubber plug of claim 6, wherein the outer surface extends outwardly from the hole to a peripheral lip portion overlying and contacting the wall of the tubular portion, the entire outer surface being convex shaped.
