## Abstract

A connector is provided that can be mounted on a surface of a substrate by reflow soldering while ensuring waterproofness due to a seal member. A cylindrical external terminal extends in an axis direction with an outer bush in close contact with an outer circumferential face of the external terminal. An inner bush is in close contact with an inner circumferential face of the external terminal. A contact pin is inserted in the inner bush along the axis direction inside the external terminal, and the outer bush and the inner bush have heat resistance durable against a temperature of reflow soldering performed when the connector is mounted on the substrate. A connector assembly, a camera module and an assembly method are also provided.

## Claims

### Claim 1

An assembly method for a connector assembly, the method comprising:
an assembly step of attaching a first seal member in close contact with an outer circumferential face of a cylindrical external conductor extending in an axis direction, attaching a second seal member in close contact with an inner circumferential face of the external conductor, and inserting an internal conductor into the second seal member along the axis direction inside the external conductor, to thereby assemble a connector;
a mounting step of installing the connector, with the first seal member and the second seal member attached thereto, on a surface of a substrate provided with solder; and
a reflow soldering step of exposing the substrate, on which the connector with the first seal member and the second seal member attached thereto is installed, to a temperature environment where the solder melts,
wherein the first seal member and the second seal member have heat resistance durable against a temperature in the reflow soldering step.

### Claim 2 (depends on 1)

The assembly method according to claim 1, wherein the first seal member and the second seal member have heat resistance durable against a temperature of 200° C. or higher.

### Claim 3 (depends on 2)

The assembly method according to claim 2, wherein the first seal member and the second seal member have heat resistance durable against a temperature of 200° C. or higher for 30 seconds or longer with a peak temperature being 260° C.

### Claim 4 (depends on 1)

The assembly method according to claim 1, further comprising a preheat step before the soldering step, wherein the preheat step is to expose the substrate having the installed connector to a temperature environment at 150° C. or higher and 180° C. or lower for 60 seconds or longer, and wherein the soldering step is to expose the substrate having the installed connector to a temperature environment at 200° C. or higher and 260° C. or lower for 30 seconds or longer.
