Abstract

A connector having insulation for electrical connection includes a housing having a concave portion, a terminal insert-molded in the housing, a lead wire electrically coupled with the terminal, a potting material for sealing the concave portion and an insulation material. The connector uses the insulation material in contact with the potting material to cover an end of the terminal extending upward in the concave portion.

Claims

1. A connector having insulation for electrical connection comprising:

a housing having a concave portion;

a terminal extending through the housing;

a lead wire electrically coupled with the terminal;

a potting material for sealing the concave portion; and

an insulation material,

wherein the insulation material in contact with the potting material covers an end of the terminal extending upward in the concave portion.

2. The connector of claim 1,

wherein the insulation material is a cap member that covers the end of the terminal.

3. The connector of claim 2,

wherein the cap member has a concavity and a convexity on an outer circumferential surface.

4. The connector of claim 3,

wherein the cap member has a protruding portion on the outer circumferential surface.

5. The connector of claim 1,

wherein a plurality of the terminals are disposed in the concave portion, and

wherein the plural ends of the terminals are covered by a cap member having an integrated form of cap members.

6. The connector of claim 1,

wherein the insulation material is a coating.
