Product Name: 4 AA (Size 5) Long Battery Holder (with Wires, No Cover)
Appearance and Structural Features:
Overall Structure: This is a slender, black, open-type battery holder designed specifically for holding four AA (Size 5) batteries. It features a single-row, vertical layout, giving it a long, rectangular shape, making it ideal for installation in narrow spaces or as an internal power compartment in handheld devices.
Materials and Manufacturing:
Shell: The main body is made of black PP (polypropylene) resin, with a smooth surface that offers good insulation and chemical resistance.
Contacts: Internally, there are high-elasticity nickel-plated spiral springs (negative terminal) and metal tabs (positive terminal) to ensure secure battery contact. The rivets are made of nickel-plated brass, providing excellent electrical conductivity.
Functional Design (Key Features):
Wired Output: Red and black wires are directly led out from the back (red wire for positive, black wire for negative). According to the drawing specifications, the wire is UL1007 26# AWG, approximately 150mm long, with stripped and tinned ends for easy soldering or terminal connection.
No-Cover Design: This model features an open frame design without a protective cover. This design is typically used when it needs to be embedded inside a device's casing, with the casing providing protection and battery retention.
Mounting Holes: There is a round screw mounting hole in the middle partition of the battery holder, allowing for secure fixation of the holder to the device's bottom plate.
Polarity Indication: Each battery slot is clearly marked with "1.5V", "AA", and positive/negative polarity symbols to prevent incorrect battery installation.
Dimension Specifications (Based on Drawing):
Total Length: 108.7mm
Width: 32.22mm
Height: Approximately 15.3mm (excluding spring protrusions)
This is a very narrow footprint, only about 3cm wide.
Electrical Characteristics: Internally, it's a series circuit design, and four AA batteries can provide a DC output voltage of 6V.
