　　fpc connectors

　　Understanding FPC Connectors

　　FPC connectors are designed to connect flexible printed circuits to other electronic components, such as printed circuit boards (PCBs), displays, or other FPCs. Flexible printed circuits, or FPCs, are made of a thin, flexible substrate (usually polyimide) that supports conductive traces. This flexibility allows FPCs to be bent, folded, or twisted without damaging the conductive pathways, making them ideal for compact and dynamic applications.

　　Key Features of FPC Connectors

　　Compact Size: FPC connectors are designed to be small and lightweight, making them suitable for applications where space is limited.

　　Flexibility: The connectors can accommodate the flexible nature of FPCs, allowing for movement and bending without compromising the electrical connection.

　　High-Density Connection: FPC connectors can support a large number of connections within a small footprint, which is essential for high-density electronic applications.

　　Reliable Contact: They provide secure and stable electrical contacts, ensuring reliable signal transmission.

　　How FPC Connectors Work

　　FPC connectors typically consist of a plastic housing with metal contacts arranged to interface with the conductive traces on the FPC. The working mechanism of FPC connectors can be understood through the following components and steps:

　　1. Contact Points:

　　The metal contacts within the FPC connector are designed to align with the conductive traces on the FPC. These contacts are usually made of copper alloy and are plated with gold or tin to enhance conductivity and prevent corrosion.

　　2. Connection Types:

　　FPC connectors come in various types, including Zero Insertion Force (ZIF), Low Insertion Force (LIF), and non-ZIF connectors. Each type has a different method for securing the FPC:

　　ZIF Connectors: These connectors have a locking mechanism that allows the FPC to be inserted without applying significant force. Once the FPC is in place, the locking mechanism is engaged to secure the connection. This design minimizes the risk of damaging the FPC during insertion.

　　LIF Connectors: Similar to ZIF connectors, LIF connectors require low insertion force but do not have a locking mechanism. They rely on the friction between the contacts and the FPC to maintain the connection.

　　Non-ZIF Connectors: These connectors require the FPC to be inserted with a certain amount of force to establish the connection. They are simpler in design but may not be as user-friendly as ZIF or LIF connectors.

　　3. Insertion and Locking:

　　To connect an FPC to an FPC connector, the following steps are typically followed:

　　Preparation: Ensure the FPC is properly aligned with the connector, matching the conductive traces with the metal contacts.

　　Insertion: Insert the FPC into the connector¨s slot. For ZIF connectors, this step requires minimal force.

　　Locking: Engage the locking mechanism (if present) to secure the FPC in place. This ensures a stable and reliable electrical connection.

　　4. Signal Transmission:

　　Once the FPC is securely connected, electrical signals can be transmitted between the FPC and the connected component (e.g., a PCB or display). The metal contacts in the connector facilitate this transmission, ensuring minimal signal loss and high reliability.

　　In the fastener forming process, cold heading (extrusion) technology is a main processing technology, which belongs to the category of metal pressure processing. In production, at room temperature, external force is applied to the metal to form the metal in a predetermined mold. This method is usually called cold heading. In fact, the forming of any fastener is not only achieved by cold heading. In the cold heading process, in addition to upsetting deformation, it is also accompanied by positive and negative extrusion, compound extrusion, punching, rolling and other deformation methods. Therefore, the name of cold heading in production is just a habitual name. To be more precise, it should be called cold heading (extrusion).At first, non standard fasteners It developed out of control and gradually opened up a sky of its own. https://jieruifasteners.com/

　　Cold heading (extrusion) has many advantages, and it is suitable for mass production of fasteners. Its advantages can be summarized as follows:

　　High steel utilization rate. Cold heading (extrusion) is a method with little or no cutting. For example, when machining hexagonal bolts and cylindrical hexagon socket screws of rod type, the steel utilization rate is only 25% to 35% by cutting method, while by cold heading (extrusion), its utilization rate can be as high as 85% to 95%, which is only some process consumption of material head, material tail and cutting hexagonal head edge.

　　High productivity. Compared with general cutting processing, the efficiency of cold heading (extrusion) is more than dozens of times higher.

　　Good mechanical properties. The strength of parts processed by cold heading (extrusion) method is much better than that of cutting processing because the metal fiber is not cut off.Suitable for automated production. Fasteners (including some special-shaped parts) suitable for cold heading (extrusion) method are basically symmetrical parts, suitable for production by high-speed automatic cold heading machine, and also the main method of mass production.

　　In short, the cold heading (extrusion) method for processing fasteners and special-shaped parts is a processing method with a very high comprehensive economic benefit. It is a processing method commonly used in the fastener industry. It is also an advanced processing method that is widely used and has great development both at home and abroad.

　　Cold heading, cold pressing:

　　At room temperature, the blank is placed in the mold of an automatic cold heading machine or a press, and pressure is applied to the mold. The relative movement of the upper and lower molds is used to deform the blank in the mold cavity, reduce the height, and increase the cross section. This pressure processing method is called cold heading for automatic cold heading machines and cold pressing for presses. In actual production, the cold forming process of fasteners is often accompanied by extrusion during the cold heading process. Therefore, the cold heading process of fastener products is actually a composite processing method that has both cold heading and extrusion.

　　Deformation methods of cold heading (extrusion):

　　1. Punching. Separate part of the blank from the main body, such as cutting of wire, punching of nuts, trimming of the head of hexagonal bolts, etc.

　　2. Upsetting. A processing method that shortens the height of the blank and increases the cross-section, such as ball upsetting of nuts, pre-upsetting and fine upsetting of bolt head forming, etc.

　　3. Positive extrusion. During cold heading, when the blank is deformed in the lower die, the flow direction of the metal is consistent with the movement direction of the upper die. The reduction of the thick rod in cold heading bolts and cylindrical head hexagon socket screws is a positive extrusion.

　　4. Reverse extrusion. During the deformation of the blank, the flow direction of the metal is opposite to the movement direction of the upper die. The head forming of the cylindrical head hexagon socket screw belongs to reverse extrusion.

　　5. Compound extrusion. During the deformation of the blank, part of the metal flow direction is the same as the movement direction of the upper die, and part is opposite to it, that is, there is both positive extrusion and negative extrusion during the deformation. For example, the cylindrical head hexagon socket screw has both rod diameter reduction (positive extrusion) and head forming (negative extrusion) during the deformation at the same station.

　　Is it better to have a multi-core cable or a single-core cable? The difference between single-core cables and multi-core cables. Power cables are generally divided into single-core, double-core and three-core cables. Among them, single-core cables refer to cables with only one conductor in one insulation layer, while double-core cables refer to cables with two conductors in one insulation layer. In fact, both have their advantages and disadvantages. For example, when the line of a single-core cable is long, when the control circuit with a large current is used or when it is laid in water, in order to prevent or reduce the middle connector, or when single-core cables have better comprehensive safety engineering than multi-core cables, single-core cables can be used.Without exception, multicore cable price Our customers are willing to purchase their products, because high quality is the concept of their products. https://www.linkcablecn.com

　　Is it better to have a multi-core cable or a single-core cable?

　　1. From the current point of view, the current passing through a multi-core cable with the same cross-sectional area is relatively larger than that of a single-core cable, and the load is large.

　　2. From the perspective of power loss, the two ends of the single-core cableare directly grounded, and the metal shielding layer of the cable may also generate circulating current that can reach the current carrying capacity of the cable, which wastes power and forms loss. Multi-core cables are generally three-core cables, because during the operation of the cable, the sum of the currents flowing through the three cores is zero, and there is basically no induced voltage at both ends of the cable metal shielding layer.

　　3. From the perspective of cost, among the wires of the same cross-sectional area, the cost of single-core cables is cheaper than that of multi-core cables, and multi-core cables are slightly more expensive.

　　4. From the perspective of installation, single-core cables appear harder when passing through pipes, while multi-core cables are softer and easier to wire.

　　The difference between single-core cables and multi-core cables

　　2-core cables: When the neutral line of 1kv and below power supplies is directly grounded, the number of cable cores of the single-phase control circuit should be 2-core cables when the maintenance line and the neutral point share the same conductor. For control circuits that can be powered by DC, 2-core cables should be used.

　　3-core cable: When the neutral line of 1kv and below power supply is directly grounded, the number of cable cores of the single-phase power control circuit is: When the protection line and neutral point are separate, it is advisable to use a 3-core cable.

　　4-core cable: 1kv and below 4-core cable (3+1 cable), in which the fourth core is used as a grounding protection, and also carries the unbalanced current and short-circuit capacity of the power supply system. (To learn more about cable technology, please click here, a lot of dry goods are waiting for you) Its size is determined by the unbalanced current and short-circuit capacity, but generally cannot be less than 1/2 of the phase line.

　　5-core cable: 1kv and below three-phase four-wire distribution room system, some electrical equipment distribution lines with higher safety requirements, and some communication centers and automation equipment that must ensure power safety and anti-interference grounding, it is advisable to use 5 copper core cable TN-C distribution room system, so that the protection line (PE line) and neutral point (PN line) are independent, and the cable core section is generally 3 large and 2 small or 4 large and 1 small or 5 large.

　　Multicore Flexible Cable supplier.jpg

　　The difference between 4-core cable and 3+1 core cable: 1kv and below three-phase four-wire distribution room system, when the protection line and neutral point share the same conductor, 4-core cable should be used, and the method of 3-core cable plus single-core cable to form a circuit cannot be used, or even the method of directly using the metal sheath or armored cable layer of 3-core cable as the neutral point. Otherwise, when the 3-phase current is unbalanced, it is equivalent to the operation of a single-core cable, which is easy to cause DC interference.
