Relay coil terminal processing! Two types of copper wire are wound, and with three terminals, two copper wires are connected to the same terminal for terminal processing.
MDS: In the electronic components processing division, we handle electronic components that support environmentally friendly products. Utilizing our cultivated precision processing technology, we produce various coils used in high-precision communication and office automation equipment (small lot production of many varieties). ■□■□■【Introducing a case study of terminal processing for relay coils!】■□■□■ 【Features】 Two-winding latching coil Two types of copper wire are wound, and terminal processing is performed by connecting two copper wires to the same terminal with three terminals. 【Challenges】 Typically, copper wire is cut using the edge of the terminal, but since two wires need to be connected, the edge of the terminal becomes difficult to use for the second wire, making it prone to whiskers. Therefore, we wound the first copper wire with a coarse pitch spiral and connected the second wire in between. In multi-axis automatic winding, variations occur on each axis, causing overlaps in the connected wires, so we repeatedly adjusted the fixtures and programs. 【Usage example】 Used in lighting relay coils At MDS, we leverage our terminal processing technology and know-how for relay coils to support coil production. *For more details, please contact us or download the catalog.
Terminal processing for relay coils! Terminal processing of stranded copper wire at the base of terminals measuring 7 to 9 mm.
MDS: In the electronic components processing division, we handle electronic components that support environmentally friendly products. Utilizing our cultivated precision processing technology, we produce various coils used in high-precision communication and office automation equipment (small-batch production of many varieties). ■□■□■【Introducing examples of terminal processing for relay coils!】■□■□■ 【Features】 We perform terminal processing on copper wire ends that are curled at the base of terminals measuring 7 to 9 mm. Normally, soldering is done, but since solder cannot adhere to the terminal tip, we apply heat while holding the copper wire with a chip to melt the plating of the terminal and carry out terminal processing. 【Challenges】 If pressed too hard, the copper wire breaks, and if pressed too lightly, it causes poor contact. We conducted repeated tests to set the conditions. 【Usage examples】 These are used in relay coils and are also utilized in the Shinkansen N700 series. At MDS, we leverage our relay coil terminal processing technology and know-how to support coil production. *For more details, please contact us or download the catalog.

The starting wire is temporarily colored on the jig core before winding. After winding is completed, a temporary color is applied to the jig core as well. 【Challenges】 The temporary colored wire is cut to extract the coil, but the length of the lead wire from the coil is designed and manufactured to be within specifications, so there is no need for further adjustments later. 【Usage Example】 It is used in lighting coils. At MDS, we leverage our winding technology and know-how for jig cores to support coil production. *For more details, please contact us or download the catalog.
Reinforce terminals of ultra-fine wire (0.03 mm or less) that are prone to disconnection with twisted wire terminal processing!
MDS: In the electronic components processing division, we handle electronic components that support environmentally friendly products. Utilizing our cultivated precision processing technology, we produce various coils used in high-precision communication and office automation equipment (small-batch production of many varieties). ■□■□■【Introducing a case study on reinforcement of relay coil terminal wires!】■□■□■ 【Features】 Due to the tendency for extremely fine wires (less than 0.03 mm) to break near the terminals, we perform twisting wire terminal processing. By using twisted wires (3, 5, and 7 strands), we have reduced the incidence of breakage near the terminals. 【Challenges Faced】 Because of the multi-axis winding (16 axes), the twisted wires (3, 5, and 7 strands) resulted in thicker wire diameters, requiring careful attention to ensure even winding of the insulation. With a terminal length of 1.5 mm, we twisted the insulation 5 times, and during soldering, we struggled with the unsoldered finish around the base, which required one complete round. 【Usage Examples】 The twisted wire type is used for coils ranging from 24V to 100V. They are mainly used in power-related control applications. At MDS, we leverage our relay coil terminal processing technology and know-how to support coil production. *For more details, please contact us or download the catalog.
