Barrel - Audio Connectors

Introduction

Barrel connectors are a type of audio connector used to connect two electrical cords for audio or video signals. This type of connector has been used in the professional and home audio-visual fields since the 1930s, and is becoming increasingly popular for all types of audio and video applications. Barrel audio connectors, also known as 3.5mm connectors, are commonly used to connect phones, laptops and gaming consoles to external speakers or headphones.

SJD-3512-45 Application Field and Working Principle

The SJD-3512-45 audio connector is a 2-contact, 3.5mm diameter connector that is commonly used in the professional audio and consumer audio-visual fields. It is designed to connect two electrical cords, and is often used in a variety of applications including connecting laptop audio out to external speakers, connecting iPods or iPhones to headphones or car stereo systems, and connecting gaming consoles to external amplifier systems. The SJD-3512-45 is a standard 2-conductor connector with an interior diameter of 3.5mm. It uses a "tapered thread" connection, which provides a secure connection between the two carbonized steel contacts. The contacts are designed so that they securely slide into the audio jack, and when tightened, they create a secure electrical connection. The design of the SJD-3512-45 ensures that the contact does not easily loosen, and it also prevents any strain or tension on the contact that could result in a broken electrical connection. When a user applies pressure to the outer portion of the connector, it forces the contact out of the audio jack, breaking the electrical connection. This is a common design feature of most barrel audio connectors because it ensures that the connection is released as soon as pressure is applied, and that the connector does not become permanently stuck inside the audio jack.

Advantages of Using the SJD-3512-45 Audio Connector

The SJD-3512-45 audio connector provides numerous advantages over other barrel audio connectors, making it an ideal choice for a variety of applications. The main advantage of the SJD-3512-45 audio connector is its reliable connection. This connector uses a "tapered thread" connection, which provides a secure electrical connection between the two contacts. This ensures that the contact does not get loose, and it also prevents any strain or tension on the contact that could result in a broken electrical connection.In addition, the SJD-3512-45 audio connector is designed with a contact that easily comes out of the audio jack when pressure is applied. This unique design feature ensures that the connection is released as soon as pressure is applied, and it also prevents the connector from becoming stuck inside the audio jack. The SJD-3512-45 audio connector is also easy to use, and it can be connected to any audio device with a 3.5mm jack. This makes it an ideal choice for connecting a variety of audio devices, and it allows users to quickly and easily connect their audio devices to the necessary audio output.

Conclusion

The SJD-3512-45 audio connector is an ideal choice for a variety of audio and video applications. This 2-contact, 3.5mm diameter connector is designed to provide a secure electrical connection, and its unique design ensures that the connection is released as soon as pressure is applied. The SJD-3512-45 audio connector is also easy to use, making it a great choice for connecting a variety of audio devices.
