Description

Technical Field

[0001] This utility model relates to the field of electronic audio equipment manufacturing, specifically to a mold for fixing the shape of lead wires. Background Technology

[0002] In the field of electronic audio equipment manufacturing, the voice coil is one of the core components in loudspeakers and other sound-producing parts. Its quality and performance directly affect the sound quality of the audio equipment. The voice coil is usually made of coil winding with leads for connecting to external circuits to transmit electrical signals, which in turn drive the voice coil to vibrate in a magnetic field to produce sound. In the production and manufacturing process of the voice coil, the handling of the leads is one of the key steps. The leads not only need to be connected to the designated positions accurately to ensure the stable transmission of electrical signals, but their shape and direction must also be precisely controlled to avoid problems such as lead shaking or tangling affecting the normal vibration of the voice coil during operation, which could lead to a decrease in sound quality or even damage to the voice coil.

[0003] Currently, the processing of voice coil leads in the industry mostly relies on manual operation or some simple auxiliary tools. Although manual operation has a certain degree of flexibility, it is inefficient and it is difficult to guarantee the consistency and accuracy of the lead shape. The forming effect of the lead may vary greatly between different workers and even when the same worker operates at different times. This poses a great challenge to the large-scale, standardized production of voice coils. At the same time, manual operation is also prone to errors, resulting in lead damage or incorrect connection, increasing the scrap rate and production costs. Therefore, we need to propose a fixture for fixing the lead shape. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fixture for determining the shape of a lead wire includes a base, a fixing block is fixedly installed inside the base, a limiting inner tube for limiting the position of a voice coil is fixedly installed at the top center of the fixing block, and a guiding component for limiting and guiding the voice coil lead wire is installed on one side of the fixing block.

[0007] The guiding component includes a support block, which is fixedly installed on one side wall of a fixed block. A guiding block is fixedly installed on the top of the support block, and a guiding groove is provided in the middle of the top of the guiding block.

[0008] The base is provided with a limiting component on one side of the top to limit the lead wire of the cooperating guide assembly.

[0013] Preferably, two sets of protrusions are symmetrically fixedly installed on the top of both sides of the base, and the two sets of protrusions are located on the same horizontal line as the axis of the limiting inner tube.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention, by setting a guiding component and a limiting component, allows the guiding block and its surface guiding groove in the guiding component to accurately guide the direction of the voice coil lead, while the limiting component can precisely limit the lead.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] A lead wire shape fixture includes a base 1, a fixing block 2 is fixedly installed inside the base 1, a limiting inner tube 3 for limiting the voice coil is fixedly installed at the top center of the fixing block 2, and a guiding component 4 for limiting and guiding the voice coil lead wire is installed on one side of the fixing block 2.

[0024] The base 1 is made of high-strength alloy material and has anti-slip texture on the bottom, which can enhance the stability of the fixture on the workbench. The fixing block 2 is integrally formed with the base 1. The outer diameter of the limiting inner tube 3 matches the inner diameter of the voice coil. The outer wall is smooth and chrome-plated, which can not only ensure that the voice coil can be smoothly inserted, but also reduce the wear between the voice coil and the limiting inner tube 3.

[0025] In an optional embodiment: the guiding component 4 includes a support block 41, which is fixedly installed on one side wall of the fixed block 2. A guiding block 42 is fixedly installed on the top of the support block 41, and a guiding groove 43 is provided in the middle of the top of the guiding block 42.

[0026] The top side of the base 1 is provided with a limiting component 5 that limits the lead wire of the cooperating guide component 4.

[0027] The height of the support block 41 is precisely calculated to ensure that the guide block 42 is at the optimal guiding height. The width of the guide groove 43 facilitates the passage of the voice coil lead wire, and the groove wall is polished with extremely low surface roughness. The guide block 42 and the support block 41 are connected by welding, and the weld joint is ground to ensure a firm connection and a smooth surface. The reasonable height of the support block 41 ensures the smoothness of lead wire guidance and avoids bending or jamming of the lead wire. The guide groove 43 reduces friction and damage to the lead wire during the guiding process and protects the integrity of the lead wire.

[0028] In an optional embodiment: the limiting component 5 includes a groove 51 formed on the top of one side of the base 1, and two sets of support columns 52 are symmetrically fixedly installed at the center of the groove 51, and the outer walls of the two sets of support columns 52 are covered with rubber sleeves 53.

[0029] It should be noted that the depth and width of the groove 51 are reasonably designed, which can accommodate the support post 52 without affecting the passage of the lead wire; the support post 52 is made of stainless steel, which has high strength and corrosion resistance; the rubber sleeve 53 has uniform thickness, a certain degree of surface elasticity, and is made of aging-resistant material. The reasonable size of the groove 51 provides a stable installation space for the support post 52, while avoiding interference with the lead wire; the material properties of the support post 52 ensure its long-term reliability; the elasticity and aging resistance of the rubber sleeve 53 can effectively buffer the collision between the lead wire and the support post 52, prevent the lead wire from being scratched, and extend the service life of the limiting component.

[0030] In an optional embodiment: the two sets of support columns 52 are located on the same horizontal line as the guide groove 43.

[0031] It should be noted that during the installation process, the positions of the two sets of support columns 52 and the guide groove 43 are calibrated using precision measuring tools to ensure that their center lines are on the same horizontal line and the error is controlled within a very small range. The setting of the same horizontal line ensures that the lead wire is subjected to uniform force during the guiding and limiting process, avoids deformation of the lead wire due to uneven force, and further improves the accuracy of the lead wire shape.

[0032] In an optional embodiment: the cross-section of the guide block 42 is L-shaped, and the edges of the guide block 42 are rounded.

[0033] It should be noted that the vertical part of the L-shaped cross-section has a moderate height, which can play a good lateral limiting role for the lead wire; the radius of the rounded corners has been optimized to ensure the smoothness of the edges without affecting the guide trajectory of the lead wire. The lateral limiting role of the L-shaped cross-section prevents the lead wire from deviating during the guide process and improves the stability of the guide. The rounded corner design avoids the lead wire being scratched by the edge of the guide block 42, protects the insulation layer of the lead wire, and also improves the safety of operation. The lead wire can be guided through both sides of the guide block 42 or through the guide groove 43.

[0034] In an optional embodiment, a through groove 6 communicating with the interior of the limiting inner tube 3 is provided at the center of the fixing block 2.

[0035] It should be noted that the diameter of the through groove 6 is slightly larger than the inner diameter of the limiting inner tube 3, and the inner wall is smooth and burr-free; the through groove 6 penetrates the upper and lower surfaces of the fixing block 2, and the connection with the limiting inner tube 3 is smooth. The through groove facilitates the passage of cables or other components inside the voice coil, providing convenience for subsequent processing of the voice coil; the smooth inner wall and smooth connection prevent the cables from being scratched, ensuring the integrity of the internal components of the voice coil.

[0036] In an optional embodiment, two sets of protrusions 7 are symmetrically fixedly installed on the top of both sides of the base 1, and the two sets of protrusions 7 are on the same horizontal line as the axis of the limiting inner tube 3.

[0037] It should be noted that the protrusion 7 is cylindrical in shape with a spherical top, which can be used to install auxiliary fixing devices.

[0038] Working principle: When using this utility model, firstly, the voice coil is placed on the outer wall of the limiting inner tube 3. The limiting inner tube 3, with its precise size matching the inner diameter of the voice coil, plays a stable limiting role for the voice coil, preventing the voice coil from shifting during subsequent processing. The lead wire on the voice coil can be guided into the limiting component 5 through the staggered side walls of the guide block 42 as needed. The lead wire on the voice coil can also be guided into the limiting component 5 through the guide groove 43. When the lead wire enters between the two sets of support columns 52 in the limiting component 5, the rubber sleeve 53 on the outer wall of the support column 52 is elastic, which can buffer the collision between the lead wire and the support column 52, prevent the lead wire from being scratched, and at the same time play a further limiting role for the lead wire, ensuring the stability of the lead wire's position during the shaping process.

[0039] Through the close cooperation of all components, the lead-shape fixture can accurately guide and stably limit the voice coil lead, ultimately forming the lead into the required shape, ensuring the processing quality and subsequent performance of the voice coil.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
