Terminal blocks are conductive connectors used to mount and interconnect electric wires. The product YL4261510000G is a type of terminal block for wire-to-board applications. In this application field, it is used to connect wires to printed circuit boards (PCB). The following sections discuss the main features of YL4261510000G terminal blocks, their working principles, and a few pros and cons of their use.

Features

The YL4261510000G is a terminal block with a 15A current rating and 4mm pitch. That means the pin distance of two adjacent pins is 4mm. This product is fully compliant with UL 1977 standard and hence can be used in UL recognised applications. It has a terminal spacing of 14.5mm, which allows for a higher number of wires to be connected in a smaller space. The terminal block also uses an open-ended screw design, allowing easy access to the blocked wires even after installation. Additionally, this product is designed for ultra-low profile applications, with a height of just 2.5mm.

Working Principles

The main components of a terminal block are a base, a metal contact, a conductor, and a clamping mechanism. The base provides support for mounting the metal contact and conductor. The metal contact is typically a spring-loaded terminal which is pressed against the conductor. The conductor is composed of either copper or aluminium and holds the currents and signals transferred by the terminal block. The clamping mechanism is used to secure the wires and the terminal block.

Specifically, for the YL4261510000G, the conductor is a metal plate which has five punchouts. The wires are then inserted through the punchouts and secured in place with the clamping mechanism. The metal contact is then inserted into the conductor and makes contact with the wires, allowing the current to be transferred.

Pros and Cons

The most obvious advantage of the YL4261510000G is its compact design. Its ultra-low profile allows for more wires to be connected in a small space, making it ideal for applications which have limited spacing. Additionally, its open-ended screw design can be easily accessed, allowing for easy installation and maintenance.

However, there are a few drawbacks to the YL4261510000G. First, its lower current rating limits its use for higher current applications. The terminal block may also be difficult to access due to its low profile, making it difficult to connect and disconnect wires. Furthermore, its open-ended screw design may reduce its reliability in situations where vibration or shocks can occur.

Overall, the YL4261510000G is an effective terminal block for wire-to-board applications with limited space. While it can be used with confidence in most environments, its use should be limited to lower current applications or applications with no risk of vibration or shocks.
