## Abstract

A connector includes a plurality of terminals, a first member made from a first resin to cover a part of a surface of each of the plural terminals, and a second member made from a second resin to cover a part of the surface of each of the plural terminals and a surface of the first member on the side opposite to the respective terminals. The plural terminals each project to be exposed from the surface of the second member. The first resin has breaking energy of 2 J or greater in a transverse direction. The second resin has a comparative tracking index of 400 V or greater.

## Claims

### Claim 1

A connector comprising:
a plurality of terminals;
a first member made from a first resin to cover a part of a surface of each of the plural terminals; and
a second member made from a second resin to cover a part of the surface of each of the plural terminals and a surface of the first member on a side opposite to the respective terminals,
wherein the plural terminals each project to be exposed from a surface of the second member,
the first resin has breaking energy of 2 J or greater in a transverse direction, and
the second resin has a comparative tracking index of 400 V or greater.

### Claim 2 (depends on 1)

The connector according to claim 1, wherein the second resin has the greater comparative tracking index than the first resin.

### Claim 3 (depends on 1)

The connector according to claim 1, wherein a flexural strength of the second resin when impregnated with oil at 150° C. for 1000 hours with respect to a flexural strength of the second resin without being impregnated with the oil is 85% or greater.

### Claim 4 (depends on 1)

The connector according to claim 1, wherein the first resin has the greater breaking energy in the transverse direction than the second resin.

### Claim 5 (depends on 1)

The connector according to claim 1, wherein:
the first resin includes at least one of polyphenylene sulfide or polybutylene terephthalate; and
the second resin includes at least one resin selected from the group consisting of polyphenylene sulfide, syndiotactic polystyrene, polyamide, and liquid crystal polymer.

### Claim 6 (depends on 1)

The connector according to claim 1, wherein an adhesive is applied between a boundary between the first member and the second member, or the first member and the second member are directly bonded to each other.
