Abstract
Description
Technical Field
[0001] This utility model relates to the field of T-iron technology, specifically a connection structure for T-irons. Background Technology
[0002] T-iron is a key structural component widely used in various electromagnetic devices. As a crucial component connecting the voice coil and the loudspeaker's magnetic circuit system, its design directly affects the loudspeaker's performance, reliability, and acoustic characteristics.
[0003] Traditional T-iron connection structures, due to long-term use, cannot effectively isolate and attenuate vibrations, which can lead to loose threads, affecting connection stability and even causing speaker performance degradation or damage. In addition, some structures are quite complex and difficult to assemble, resulting in increased costs. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] In view of the shortcomings of the prior art, this utility model provides a T-iron connection structure to solve the problems mentioned in the background art.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a T-iron connection structure, including a shell, a T-iron body sleeved on the inner side of the shell, studs installed on the side of the shell, and a buffer plate installed on the bottom of the shell.
[0008] Preferably, there are eight studs, which are circumferentially distributed on the outer shell, and spring washers are fitted on the outer side of each stud.
[0009] Preferably, a number of ribs are installed on the outer side of the T-iron body, the ribs are circumferentially distributed on the T-iron body, and the outer and inner edges of the T-iron body are provided with rounded corners.
[0010] Preferably, the surface of the buffer plate is provided with several through grooves, and the material of the buffer plate is rubber.
[0011] Compared with the prior art, this utility model provides a T-iron connection structure with the following advantages: The eight studs on the outer shell of this T-iron connection structure are evenly distributed, which can evenly distribute the connection load on the outer shell, thereby avoiding stress concentration and providing stronger connection strength. The spring washers on the studs can increase the friction between the threads and effectively lock the connection. The buffer plate at the bottom of the outer shell can effectively absorb and attenuate the impact and vibration from the outside, and protect the T-iron body and the entire assembly. Several ribs on the outer side of the T-iron body can resist vibration and deformation. The rounded corners of the T-iron body can effectively disperse stress and avoid stress concentration on sharp edges, thereby significantly improving the fatigue strength of the T-iron body, extending its service life, and ensuring that the speaker can work stably and reliably for a long time.

[0016] 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.
[0017] like Figure 1-3 As shown, this utility model provides a technical solution: a T-iron connection structure, including a shell 1, a T-iron body 3 sleeved on the inner side of the shell 1, a stud 2 installed on the side of the shell 1, and a buffer plate 6 installed on the bottom of the shell 1.
[0018] Furthermore, there are eight studs 2, which are circumferentially distributed on the outer shell 1, and spring washers 5 are fitted on the outer side of the studs 2.
[0019] Specifically, the eight studs 2 distributed circumferentially distribute the load evenly, providing stronger connection strength. The spring washer 5 continuously applies pressure to the studs 2, increasing the friction between the threads and preventing the studs 2 from loosening due to vibration, impact, or other reasons.
[0020] Furthermore, several ribs 4 are installed on the outer side of the T-iron body 3. The ribs 4 are distributed circumferentially on the T-iron body 3, and the outer and inner edges of the T-iron body 3 are rounded.
[0021] Specifically, the rib 4 increases the strength and rigidity of the T-iron body 3, resisting vibration and deformation. The rounded corners can disperse the stress concentration of sharp edges, improve the fatigue strength of the T-iron, and prevent cracks or fractures caused by long-term vibration.
[0022] Furthermore, the surface of the buffer plate 6 is evenly provided with several through grooves, and the material of the buffer plate 6 is rubber.
[0023] Specifically, rubber has good elasticity, which can absorb impact and vibration energy, reduce the vibration and impact force transmitted from the outer shell 1 to other parts, and improve the performance.
[0024] Working principle: First, studs 2 are installed on the side of the outer shell 1. The studs 2 fix the entire assembly to the internal bracket of the speaker. A buffer plate 6 is installed at the bottom of the outer shell 1. The buffer plate 6 is used to protect the T-iron body 3 and the entire assembly. Second, several ribs 4 are installed on the outer side of the T-iron body 3 to reduce deformation. The outer and inner edges of the T-iron body 3 are rounded to disperse stress. Finally, spring washers 5 are sleeved on the outer side of the studs 2 to prevent the assembly from loosening.
[0025] 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.
