1. บทนำ

This manual provides comprehensive instructions for the installation, operation, and maintenance of the Kenable 5.5 x 2.5 mm DC Power Female Panel Mount Solder Terminal Jack PCB Adapter. Please read this manual thoroughly before use to ensure proper functionality and safety.

2. สินค้าหมดview

The Kenable 5.5 x 2.5 mm DC Power Female Panel Mount Solder Terminal Jack is a robust connector designed for integrating DC power input into various electronic projects and devices. It features a female barrel connector compatible with standard 5.5mm outer diameter and 2.5mm inner diameter DC power plugs. The rear of the connector provides solder terminals for secure and permanent attachment to a Printed Circuit Board (PCB) or direct wiring. It is also designed for panel mounting, allowing for a stable and accessible power input port on an enclosure.

3. การตั้งค่าและการติดตั้ง

Proper installation is crucial for the reliable operation of the DC power jack. This section outlines the steps for panel mounting and soldering connections.

3.1 เครื่องมือที่จำเป็น

• หัวแร้งและตะกั่วบัดกรี
• ระบำลวด
• Small wrench or pliers (for mounting nut)
• Drill with appropriate bit (for panel hole, if not pre-drilled)
• Multimeter (for continuity and polarity checks)

3.2 การติดตั้งแผง

1. Prepare Panel Hole: Ensure the panel has a circular hole of appropriate diameter (typically around 11mm, as indicated in Figure 3.1, but verify with the specific product dimensions) for the threaded barrel of the jack.
2. ใส่แจ็ค: Insert the threaded barrel of the DC power jack through the prepared hole from the front of the panel.
3. Secure with Washer and Nut: Place the flat washer over the threaded barrel from the rear of the panel, followed by the hexagonal mounting nut. Tighten the nut securely using a wrench or pliers, ensuring the jack is firmly seated and does not rotate.

3.3 Electrical Connections (Soldering)

The jack typically has three solder terminals at the rear. Standard configuration is as follows:

• พินกลาง: This terminal connects to the positive (+) voltage of the DC power supply.
• Outer Barrel (Sleeve): This terminal connects to the negative (-) voltage (ground) of the DC power supply.
• Switch Terminal (Optional): Some jacks include a third terminal that acts as a switch, typically connecting to the outer barrel when no plug is inserted and disconnecting when a plug is inserted. Verify its function with a multimeter if unsure. For basic power input, the center pin and outer barrel terminals are used.

1. ระบุเทอร์มินัล: Use a multimeter to confirm the polarity of each terminal (center pin, outer barrel, and switch if present). The center pin is usually positive, and the outer barrel is ground.
2. เตรียมสายไฟ: Strip a small amount of insulation (approx. 3-5mm) from the wires you intend to connect.
3. Tin Wires and Terminals: Apply a small amount of solder to the stripped wire ends and the jack's terminals to ensure good electrical contact.
4. การเชื่อมต่อประสาน: Carefully solder the positive wire to the center pin terminal and the negative/ground wire to the outer barrel terminal. If using the switch terminal, connect it as required by your circuit design. Ensure strong, clean solder joints without bridging connections.
5. ตรวจสอบการเชื่อมต่อ: After soldering, use a multimeter to check for continuity and to ensure there are no short circuits between terminals.

4. คู่มือการใช้งาน

Once the DC power jack is correctly installed and wired, its operation is straightforward.

1. เตรียมแหล่งจ่ายไฟ: Ensure your DC power supply has a male plug with a 5.5mm outer diameter and 2.5mm inner diameter, and that its voltage and current ratings are compatible with your device.
2. Connect Power Plug: Carefully insert the male DC power plug from your power supply into the female jack. Ensure it is fully seated.
3. ตรวจสอบพลังงาน: Confirm that your device is receiving power. If not, refer to the Troubleshooting section.
4. ตัดการเชื่อมต่อไฟฟ้า: To disconnect, gently pull the male DC power plug straight out from the jack. Avoid pulling by the cable to prevent damage.

สำคัญ: Always ensure the polarity of your power supply matches the wiring of the jack to prevent damage to your electronic device.

5. การบำรุงรักษา

The Kenable DC Power Jack is a passive component and requires minimal maintenance.

• การตรวจสอบปกติ: Periodically inspect the jack for any signs of physical damage, corrosion, or loose connections.
• การทำความสะอาด: If dust or debris accumulates in the barrel, gently clean it using a dry, non-conductive brush or compressed air. Avoid using liquid cleaners directly on the contacts.
• ความสมบูรณ์ของการเชื่อมต่อ: Ensure that the panel mounting nut remains tight and that soldered connections are secure. Re-solder any cold or fractured joints if necessary.
