<span style=" Font family: Black font, SimHei; font-size: 18px; " &In the fields of electronic manufacturing and industrial automation, reliable electrical connections are the cornerstone of stable equipment operation. IDC Piercing Connector; The Insulation Displacement Connector has become one of the important connection solutions in the field of electronic assembly due to its ability to conduct without welding and quickly puncture the insulation layer. This article will systematically introduce the working principle, type classification, andof IDC connectors; IDC ribbon cable; The application, line pressing operation method, and; Xunpu Electronics; As an example, introduce the suppliers of IDC connectors to help readers fully understand this connection technology. <span style=" Font family: Black font, SimHei; font-size: 16px; " &The IDC puncture connector is a type of connector that utilizes insulation displacement technology to achieve electrical connections. The internal metal points are equipped with sharp blade structures. When the insulated wire is pressed into the connector slot, the blade will cut through the insulation layer and make real contact with the internal conductor, thus forming an electrical path. The entire process does not require pre stripping of wires, nor does it require welding or crimping of terminals. 1. Insert the wire into the slot; Place insulated wires in the connector; 2. Apply pressure; Use specialized crimping tools or manually press the cover plate to press the wire down into the blade. 3. Blade piercing insulation layer; The metal blade cuts through the insulation layer with precise angle and force, without damaging the internal conductor. 4 Form electrical contact; The knife edge forms a high-pressure metal to metal contact with the surface of the conductor, with a stable contact area and low resistance. This contact method is similar to; Yu& quot; Cold welding& quot; effect. · No need to strip the wire; Directly operate wires with insulation layers, simplifying the process. · Reliable Connection; Metal to metal airtight contact, low contact resistance, and vibration resistance. <span style=" font-size: 16px; Font family: Black font, SimHei; " ≫: Each IDC connector has its applicable wire diameter range (such as AWG22-28), exceeding this range may result in incomplete puncture; 2、 IDC connector classification and structure; <span style=" Font family: Black font, SimHei; font-size: 16px; " &Among them,; Bull horn connector; Named after its resemblance to cow horns in appearance, it usually has a more stable lock or fixing structure, with high connection reliability, and is widely used in industrial equipment. Jianniu connector; The structure is relatively compact, with common spacing specifications of 2.0mm, 2.54mm, etc., suitable for high-density PCB layout. < img src=" https://en.xunpu.com.cn/uploadfile/ueditor/image/202609/17888526834f35e6.jpg" ; title=" First Picture 2; alt=" First Picture 2; width=" 300" height=" 230" border=" 0" vspace=" 0" > <span style=" Font family: Black font, SimHei; font-size: 20px; " ≫ Jian Niu

; : Engineering plastics such as PBT and PA66 are usually used to provide insulation protection and mechanical fixation, and must meet UL94V-0 or V-2 flame retardant rating. · Metal piercing contact; : Core components are often made of phosphor bronze or wrinkled copper alloy materials, with tin or gold plating on the surface to ensure conductivity and corrosion resistance. · Wire trough/positioning structure; : Ensure that the wires are accurately aligned with each puncture blade. : Such as wire clamps, sheaths, etc., to prevent wires from falling off the connector when subjected to external forces. <span style=" Font family: Black font, SimHei; font-size: 16px; " ≫: Used to evenly apply pressure to ensure consistent puncture effect. Connectors of different specifications may require different types of crimping tools. · Multimeter; · Wire; <span style=" Font family: Black font, SimHei; font-size: 16px; " &The wire diameter needs to match the connector specifications. For example, if the connector is nominally suitable for AWG22-28, wires within this range should be used. 1. Confirm direction; Find the color bar (Pin1 mark) on the cable and align it with the Pin1 mark on the connector. Wrong direction can lead to mixed signal correspondence; 2. Place the ribbon cable; Place the IDC cable flat into the wire slot of the connector, ensuring that all wires are evenly distributed in their respective positions. 3. Cover the crimping cover plate; Buckle the upper cover (pressure plate) of the connector onto the cable and connector body. 4. Apply pressure; Use crimping pliers to evenly press down the cover plate until it is completely locked with the connector body. Attention: It should be crimped in place at once to avoid repeated; 5. Check the lock; Confirm that the cover plate is fully inserted into the buckle of the connector body and the cable cannot be easily pulled out. 6. Continuity test; Use a multimeter to measure the conductivity of each core wire one by one, ensuring that all connections are normal and there are no short circuits between adjacent core wires. · Wire diameter matching; <span style=" Font family: Black font, SimHei; font-size: 16px; " &Using wires that exceed the applicable wire diameter range of the connector may result in incomplete puncture (wire diameter too large) or poor contact (wire diameter too small). · Avoid repeated disassembly and assembly; <span style=" Font family: Black font, SimHei; font-size: 16px; " ≫: The puncture blade of IDC connectors will deform after crimping, and repeated disassembly and assembly will reduce their puncture ability. Most IDC connector designs; <span style=" Font family: Black font, SimHei; font-size: 16px; " &When used in damp, dusty, or corrosive gas environments, models with corresponding protection levels should be selected, or the connection should be sealed and protected.
