Abstract

Provided is a connector that can enhance the waterproof performance without reducing a pressure of a contact surface between fillers in a fitted state. A connector (10) according to the present disclosure includes a pair of fitting objects to be fitted to each other and a filler (70), a contact (50) and a wall (42) provided in the fitting objects. The wall (42) separates the filler (70) and the contact (50) after the fitting objects are fitted to each other.

First claim

The invention claimed is:

1. An electrical connector, comprising:
a first fitting object and a second fitting object to be fitted to each other;
a contact disposed in said first fitting object;
a filler disposed in said first fitting object and said second fitting object; and
a wall formed in said second fitting object, wherein
said wall is disposed inside said filler and, in a fitting state where said first fitting object and said second fitting object are fitted to each other, is disposed outside said contact and separates said filler and said contact, and wherein
said first fitting object and said second fitting object include a space configured to accommodate an excessive portion of said filler.

2. The electrical connector according to claim 1 , wherein said wall protrudes to a fitting side beyond said filler.

3. The electrical connector according to claim 1 , wherein said wall is disposed outside said contact in a direction orthogonal to a direction in which said first fitting object and said second fitting object are fitted to each other.

4. The electrical connector according to claim 1 , wherein said wall is disposed along an inner peripheral surface of said filler that surrounds said contact in said fitting state.

5. The electrical connector according to claim 1 , wherein
said wall is provided to both of said first fitting object and said second fitting object; and
in said fitting state, one said wall is adjacent to another said wall along a direction perpendicular to a fitting direction.

6. The electrical connector according to claim 1 , wherein said wall separates said filler and said contact in an expanded state where said first fitting object and said second fitting object are expanded.

7. The electrical connector according to claim 1 , wherein said wall is disposed along an inner peripheral surface of said filler that surrounds said contact in an expanded state where said first fitting object and said second fitting object are expanded.

8. The electrical connector according to claim 1 , wherein said wall is disposed around said contact in said fitting state.

9. The electrical connector according to claim 1 , wherein said space is formed by a recess provided in an outer surface of said wall that faces said filler.

10. The electrical connector according to claim 1 , wherein
said first fitting object and said second fitting object are connected to each other by a connecting portion;
said second fitting object holds a cable; and
said contact is electrically connected with said cable in said fitting state.

11. The electrical connector according to claim 10 , wherein
said contact includes a press-contact groove;
said second fitting object holds at least two said cables; and
said contact electrically connects said cables to each other with core wires of said cables clamped by said press-contact groove in said fitting state.

12. The electrical connector according to claim 10 , wherein said wall includes a notch configured to hold said cable.
