• Materials for DIP Switches

  Sep 18, 2024

      DIP switches, also known as "dual in-line package switches," typically consist of a housing, pins, contacts, springs, and a toggle part.1. Plastic Materials:The outer shell of most DIP switches is made of plastic due to its good insulating and flame-retardant properties, as well as its ease of molding and surface treatment. However, plastic materials have lower mechanical strength and are susceptible to damage from external forces.2. Metal Materials:Metal materials offer higher strength and wear resistance compared to plastic, making them suitable for applications where durability is crucial, such as transportation and shipbuilding. Nevertheless, metal materials come with challenges related to conductivity and oxidation.3. Ceramic Materials:Although ceramic materials are more expensive, they provide excellent temperature resistance, wear resistance, and mechanical strength. DIP switches used in high-temperature and high-pressure environments often utilize ceramic. However, ceramic materials are brittle and prone to breakage from external impacts.Each material has its unique characteristics and is chosen based on the specific requirements of the application. If you have any further questions or would like to discuss the selection of materials for DIP switches in more detail, please feel free to reach out.

• Requirements for Terminal Block Wire Insertion

  Sep 18, 2024

    Terminal Block wire insertion is a crucial aspect of electronic component connection, commonly used to link wires and electronic components in circuits such as sockets, batteries, and switches. This method of connection is characterized by its plug-in nature, with fasteners securing the wire to the terminal to enhance reliability and stability.There are several key requirements for terminal wire insertion:1. Wire diameter and length: The diameter and length of the wire should be determined based on the requirements of the electronic components being connected. Wire that is too thick or too thin can hinder insertion into the terminal, while wires that are too long or too short may result in improper insertion or poor contact.2. Wire material: The wire material should possess a certain level of elasticity and conductivity to generate the required insertion force when plugged into the terminal, ensuring stable and reliable circuit connections.3. Insertion force: A certain degree of insertion force must be applied when inserting the wire into the terminal to ensure good contact. Insufficient force can lead to poor contact, while excessive force may damage the terminal or wire.4. Fastening method: The method used to secure the wire to the terminal should prevent loosening or detachment during use.5. Temperature range: The wire's operating temperature range should be compatible with the electronic components being connected to maintain stable connection performance in various working environments.Terminal wire insertion is widely utilized in the manufacturing of electronic components, such as electronic switches, communications, and computers. Strict adherence to the requirements for wire insertion is essential in the manufacturing process for ensuring optimal performance.If you have any further questions or require assistance, please do not hesitate to contact us.

• PCB Terminal Block Aging Causes and Testing Methods

  Aug 13, 2024

  The aging of PCB terminal connections can be caused by various factors. Firstly, environmental conditions and temperature play a significant role. High temperatures in the surrounding environment or from heat sources can cause the terminals to overheat, leading to insulation breakdown and even explosions or fires.Secondly, chemical corrosion can also contribute to the aging of terminals. Prolonged exposure to chemical or electrolytic corrosion can degrade the protective insulation layer, reducing insulation effectiveness and accelerating aging.Lastly, operating at overload for extended periods can cause terminals to overheat due to the heating effects of current flow. Excessive temperatures can speed up insulation aging, particularly in summer months.To test for terminal aging, one method involves placing five terminals horizontally on a rail, connecting them with rated cross-section wires at least 300mm long, and measuring the voltage drop across each terminal. The test should be conducted in an aging chamber with temperature limits of 20°C to 75°C and a maximum working temperature of 120°C.During the test, a rated current flows through the terminals for both heating and cooling cycles, with voltage drop measurements taken after every 24 cycles to assess aging. The entire testing process consists of 192 cycles.Prior to testing, the voltage drop should not exceed 3.2mV. Regular monitoring of voltage drop can help identify aging terminals and prevent potential failures.If you have any further questions or require assistance with terminal aging testing, please do not hesitate to contact us.

• What is a terminal on a circuit board?

  Jul 31, 2024

  On a circuit board, terminals are metal pins or sockets for electronic components or wires. They serve as connection points and provide physical and electrical connections between electronic components and circuit boards. Here are some common types of terminals on circuit boards:   1. Socket terminals: Socket terminals are usually holes or slots made of metal for inserting pins of electronic components (such as diodes, resistors, integrated circuits, etc.). Socket terminals can provide stable and reliable connections, facilitating the plugging and unplugging and replacement of components.   2. Pin terminals: Pin terminals are metal pins of the electronic components themselves, which are connected by welding or inserting into holes on the circuit board. They can be in different forms such as straight-in pins, surface-mount pins, package pins, etc., used to connect electronic components to circuit boards.   3. Stud terminals: Stud terminals are usually used to connect high-power components or wires, such as motors, power supplies, resistors, etc. They usually have a threaded structure, and the wires are clamped and an electrical connection is established by tightening the nut.   4. Spring contact terminals: Spring contact terminals use spring force to provide a tight connection. They are usually used in occasions that require frequent plugging and unplugging, such as test points or connecting external devices.   5. Blade terminals: Blade terminals are similar to socket terminals, but are usually used for high current applications. They have blade-shaped pins that can quickly connect electronic components by plugging and unplugging.  Our team has extensively tested and evaluated the Homnecks connector terminals and we are pleased to report that they have displayed excellent performance and reliability. The terminals have shown exceptional conductivity and durability, ensuring secure and stable connections on the PCB boards. Furthermore, the use of Homnecks connector terminals has proven to be incredibly efficient and user-friendly. The terminals are easy to install and provide a secure connection without the need for additional tools or complicated processes. This not only saves time during assembly but also reduces the risk of errors or malfunctions. The function of the terminal is to provide a reliable electrical connection on the circuit board, allowing electronic components to pass current and signals to and from the circuit board. They allow for assembly, maintenance and testing of circuit boards, and provide flexibility and convenience. Different types of terminals are suitable for different connection needs and are selected according to the specific application and component type.
