1 AAA plug-in battery holder, direct insertion type

Product Name: 1-Cell AAA  Battery Holder (Through-hole Type)

Appearance and Structural Features:
Overall Structure: This is a minimalist black single-cell battery holder designed specifically for holding one AAA  battery. It features an open-frame design without a fully enclosed shell, significantly reducing its size and weight.

Materials and Manufacturing:
Shell: The main body is made of black PP (polypropylene) resin material, which provides good insulation. The drawing indicates its flame retardant rating as UL94-HB, with a working temperature range of -10°C to 80°C.
Contacts and Pins: One end inside features a high-elasticity nickel-plated spiral spring (specification: 0.64mm 65C spring wire), while the other end has metal protrusions. The most notable feature are the metal tabs (solder pins) extending from both ends. This design allows the battery holder to be directly inserted into circuit board holes for soldering or used in conjunction with sockets. The rivets are made of nickel-plated brass.

Functional Design (Key Features):
No Switch Design: This model does not have an integrated power switch and is designed to be always on.
PCB Mounting: Mounting holes (diameter φ2.65mm) are provided on both sides of the bottom, which, along with the metal tabs, make it very suitable for securing on a PCB board.

Dimension Specifications (Based on Drawings):
Total Length: 50.30mm
Width: 13.05mm
Height: 12.10mm
Mounting Hole Diameter: φ2.5mm
Electrical Characteristics: The single AAA battery provides a DC output voltage of 1.5V. Complies with RoHS environmental standards.
