Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of electromagnetic coil manufacturing, especially relates to a electromagnetic coil wire rack. BACKGROUND
[0002] In the application of electromagnetic coil, the wire rack plays a crucial role. Its main function is to organize and fix the enameled wire, ensuring the enameled wire to be arranged in order, and providing a stable support structure for winding. The traditional wire rack design usually includes a main body for winding enameled wire, and a pin for leading out the wire. After the enameled wire is wound on the wire rack main body to the required number of turns, it is wound on the two pins respectively through the wire rack gap, and then the current is led through the conductive sheet to realize the energization of the electromagnetic coil.
[0003] The gap used is a straight slot or other single-shaped gap, which provides fewer fixing points. The enameled wire is more likely to shift or loosen during the winding process. The single-shaped gap cannot provide a clear and orderly wiring path for the enameled wire, especially in the case of multi-layer winding, the enameled wire between different layers is easy to mix and interleave. This not only increases the wiring difficulty, but also may cause difficulty in subsequent maintenance and inspection. At present, a cylindrical welding sleeve is generally used to wrap the enameled wire wound on the pin, and then the enamel is melted away using resistance welding at high temperature, so as to fasten the welding sleeve and the enameled wire together. Due to the larger contact area of the cylindrical welding sleeve, it encounters greater resistance during pressing, making the pressing operation difficult and laborious. When pressing the cylindrical welding sleeve, due to the larger contact area and the applied pressure, the uniformity of the enameled wire winding is easily damaged, affecting the overall performance of the coil. This not only may cause unstable electrical characteristics, but also may reduce the mechanical strength of the coil.
[0004] The utility model discloses a kind of electromagnetic coil wire racks to solve the above technical problems. UTILITY MODEL CONTENTS

[0026] An electromagnetic coil wire holder, characterized by comprising a framework main body 1, a wire holder 2 and a welding sleeve, the wire holder 2 is fixedly connected on the framework main body 1, a first conductive sheet 3, a second conductive sheet 4, a first pin 5 and a second pin 6 are installed on the wire holder 2, the first conductive sheet 3 is connected with the first pin 5, the second conductive sheet 4 is connected with the second pin 6, a wire holder gap is arranged on the wire holder 2, and the welding sleeve is wrapped and wound on the first pin 5 and the second pin 6.
[0027] The wire holder clamping gap is a stepped wire holder clamping gap. The stepped design can better fix the position of the enameled wire, making the coil winding more compact and orderly. This structure can provide multiple contact points to keep the enameled wire stable, preventing it from shifting or loosening during coil operation. The stepped wire holder clamping gap helps guide the enameled wire from the skeleton body 1 to the needle, ensuring a clear and easy-to-control lead-out line path. This not only simplifies the wiring process, but also improves production efficiency. With the stepped design, a more compact layout can be achieved in limited space. Each step can be used to place different layers of enameled wire, making full use of available space and making the entire coil assembly more compact. If the coil needs to be repaired or inspected, the stepped clamping gap makes it easier for technicians to identify and handle each part, simplifying the maintenance process.
[0028] As shown in Figures 1 to 5 The skeleton body 1 includes an upper ring 11, a main cylinder 12, and a lower ring 13, and the upper ring 11 has a wire clamping groove 111. The wire clamping groove 111 can help fix the starting or ending end of the enameled wire, ensuring that they do not shift during the coil winding process. This helps improve the stability of the coil and prevents the enameled wire from loosening due to vibration or other external forces during use. The main cylinder 12 is a hollow cylinder, and the hollow main cylinder can serve as part of the heat dissipation channel, helping to dissipate heat generated by the electromagnetic coil during operation. Good heat dissipation performance is crucial to ensure the long-term stable operation of the coil, especially in high-power or long-time operation applications.
[0029] The skeleton body 1 is made of insulating material, such as plastic or ceramic. Its role is to provide a winding support structure for the enameled wire, preventing unnecessary electrical contact between the enameled wire and other components, ensuring that the current flows along the intended path, avoiding problems such as leakage or short circuit.
[0030] The conductive sheet and needle must have good electrical conductivity. After the current from the external power source, it first passes through the conductive sheet and then through the needle to the enameled wire, thereby generating a magnetic field in the electromagnetic coil. The needle is an important component that connects the conductive sheet and the coil. The conductive sheet is an important hub for the current to enter the electromagnetic coil.
[0031] The wire holder 2 includes a wire holder channel 21, a first conductive sheet mounting seat 22, and a second conductive sheet mounting seat 23, the first conductive sheet mounting seat 22 and the second conductive sheet mounting seat 23 are respectively installed with the first conductive sheet 3 and the second conductive sheet 4, the bottom of the first conductive sheet mounting seat 22 and the second conductive sheet mounting seat 23 is fixedly connected with the first needle seat and the second needle seat, the first needle seat and the second needle seat are respectively installed with the first needle 5 and the second needle 6, and the wire holder clamping gap is provided on the wire holder channel 21. The conductive sheet and the needle are connected inside the wire holder 2.
[0032] The lower ring 13 is provided with a slit-shaped passage consistent with the shape of the bobbin clamp. By providing a slit-shaped passage on the lower ring 13 consistent with the shape of the bobbin clamp, it can ensure that the path of the enameled wire from the bobbin body to the needle foot is continuous and orderly. This helps to prevent the enameled wire from being tangled or intertwined during the winding or assembly of the coil. This design simplifies the wiring process, allowing workers to more quickly and accurately guide the enameled wire out to the needle foot position. For automated production lines, this consistency also helps to achieve a higher degree of automation and higher production efficiency.
[0033] As shown in Figure 6 The welding sleeve is a C-shaped welding sleeve.
[0034] As shown in Figure 7 The welding sleeve is a U-shaped welding sleeve.
[0035] The function of the welding sleeve is to firmly fix the enameled wire wound on the needle foot. During the operation of the electromagnetic coil, the current needs to be transmitted through the enameled wire. If the enameled wire is not firmly connected to the needle foot, it will cause poor contact, affect the current transmission effect, and even may make the electromagnetic coil unable to work normally. By using a welding sleeve and welding, such as a C-shaped or U-shaped welding sleeve, the enameled wire can be tightly combined with the needle foot, ensuring stable transmission of current between the enameled wire and the needle foot, and ensuring the power performance of the electromagnetic coil.
[0036] Compared with the traditional cylindrical welding sleeve, the C-shaped welding sleeve has improved structure. Its faces are not coincident, reducing material costs. In terms of operation, due to the reduced contact area, pressing is easier, and operation is simpler and more convenient, indirectly improving welding efficiency. During the welding process, the C-shaped welding sleeve does not have as much resistance as the cylindrical welding sleeve when pressed due to the large contact area, and it is not easy to damage the uniformity of the enameled wire winding, making the welding process more smooth and efficient.
[0037] During resistance welding, the welding sleeve will be subjected to stress due to extrusion. The C-shaped or U-shaped welding sleeve can effectively alleviate the impact of this stress on the enameled wire. For example, when the C-shaped welding sleeve is extruded, the stress generated can extend in the direction without a face, reducing the pressure on the enameled wire, thereby protecting the enameled wire from being excessively extruded or damaged, prolonging the service life of the enameled wire, and thus ensuring the reliability and stability of the electromagnetic coil.
[0038] To prevent the enameled wire from shifting to the side of the C-shaped or U-shaped solder sleeve that is not wrapped, during the installation of the C-shaped or U-shaped solder sleeve, the enameled wire can be fixed by designing an appropriate pre-tightening force. For example, before soldering, a certain pressure is applied gently using a clamp or other tool to make the solder sleeve tightly fit the enameled wire, but without causing excessive stress. Some auxiliary fixing structures, such as small protrusions or grooves, can be designed on the solder sleeve to further limit the position of the enameled wire. These structures can increase additional stability without affecting the soldering effect.
[0039] The method of using the device is as follows:
[0040] Coil winding stage:
[0041] Prepare enameled wire of appropriate specifications, ensuring that its quality meets the requirements. Begin to evenly wind the enameled wire on the cylindrical structure of the main cylinder 12 to form the required number of coil layers.
[0042] After reaching the specified number of turns, the two ends of the enameled wire are guided to the first pin 5 or the second pin 6 through the passage on the lower ring 13 and the wire stand clamps 71, 72. Different layers of enameled wire can be managed and fixed through corresponding steps (first step 71 and second step 72), avoiding confusion and interlacing between different layers.
[0043] Connection and fixation stage:
[0044] Tightly wrap the two ends of the enameled wire around the first pin 5 and the second pin 6, ensuring reliable electrical connection.
[0045] According to the design, choose a C-shaped solder sleeve or a U-shaped solder sleeve to wrap around the pins on which the enameled wire is wound. Use resistance welding or other appropriate methods to fasten the solder sleeve, ensuring that the mechanical and electrical connection between the enameled wire and the pin is firm and durable.
[0046] Perform functional tests on the assembled electromagnetic coil, including but not limited to inductance value measurement, voltage withstand test, etc., to verify whether its performance meets the design requirements.
[0047] When using a C-shaped solder sleeve, wrap the C-shaped solder sleeve around the enameled wire wound on the pin. Since the C-shaped solder sleeve is not a complete closed surface, it has less surface contact than the traditional cylindrical solder sleeve, making it easier to press and operate, indirectly improving the soldering efficiency, and reducing the risk of wear on the enameled wire during pressing.
[0048] When using a U-shaped solder sleeve, its working method is basically the same as that of the C-shaped solder sleeve. However, the U-shaped solder sleeve has higher flexibility in operation, as it is no longer limited to vertical pressing along the pin direction, but can also be pressed from the side of the pin to contact the enameled wire, further simplifying the operation process.
[0049] An external power source is connected to the first and second conductive tabs 3, 4. Current flows from the conductive tabs to the pins, to the enameled wire, and along the enameled wire to create a magnetic field.
[0050] The utility model is described above by way of example, but the utility model is not limited to the above specific embodiments, any modification or variation made on the basis of the utility model belongs to the range claimed by the utility model.
