[0001] This utility model relates to a connection structure, and more particularly to an audio device connection structure, related detection device and components. Background Technology

[0002] In today's society, concerts and performances are increasingly common as an important way to relieve stress and provide emotional support. Singers on stage need high-end audio equipment to ensure sound quality and transmission for a captivating performance. However, due to the dynamic nature of stage performances, such as singers' movements and stage height adjustments, audio equipment cables (e.g., those for waistpack microphones) face various risks. Cables are susceptible to pulling, bumping, and impacts from drops. Especially when the stage has height adjustments, the drop height of audio equipment increases significantly, placing greater stress and impact on the connection ports.

[0003] While high-end audio equipment on the market currently uses male and female connectors with nuts and studs to ensure stable connections, the lack of clear industry requirements for the torsional and drop resistance of audio equipment ports results in many ports being weak and unstable. This makes the ports prone to loosening after a drop, easily breaking with a twist or even from a fall, severely impacting audio transmission quality and the smooth running of stage performances.

[0031] The following, in conjunction with the accompanying drawings and preferred embodiments of the present invention, further illustrates the technical means adopted by the present invention to achieve its intended purpose.

[0032] like Figures 1 to 4 As shown, an optional embodiment of this utility model provides an audio device connection structure, including an insulating housing 1, a metal terminal 2, and a connector 3.

[0033] The insulating housing 1 includes a base 11 and a cover 12. Three positioning posts 13 are provided on the top of the base 11, and a corresponding number of positioning holes 14 are provided on the cover 12. The diameter of the positioning posts 13 is slightly larger than the diameter of the positioning holes 14. The cover 12 can be pressed onto the base 11 using a jig to assemble the insulating housing 1, thus preventing internal components from being impacted. The insulating housing 1 is preferably made of plastic.

[0034] See Figure 3 and Figure 4 The base 11 of the insulating housing 1 is used to accommodate the metal terminal 2. Specifically, the base 11 is provided with a terminal slot 15 and multiple through holes 16 at the bottom. The terminal slot 15 can hold the metal terminal 2 inside, and some of the through holes 16 are used to assemble the metal terminal 2. Further, the base 11 includes four side walls. One of the side walls has a U-shaped opening 18, and the other three side walls are closed side walls. The U-shaped opening 18 is used to accommodate the connector 3. The side wall with the U-shaped opening 18 has a certain thickness, and a slot 19 for holding the connector 3 is provided inside the side wall.

[0035] The metal terminal 2 includes a retaining portion 21 and a lead portion 22. For example... Figure 1 As shown, the retaining part 21 is a sheet-like body, which can be fixed in the terminal slot 15 by clamping. After the retaining part 21 of the metal terminal 2 is fixed in the terminal slot 15 of the base 11, the lead part 22 passes through a portion of the through hole 16 at the bottom of the base 11 and extends out from the through hole 16 for soldering wires to achieve the conduction function. Further, see Figure 4 A spring 20 is provided between the exposed portion of the retaining part 21 and the base 11. The compression action of the spring 20 ensures the stability of the retaining part 21, thereby ensuring stable contact between the metal terminal 2 and the external male plug during operation.

[0036] The connector 3 includes a connecting stud 31 and a fixing plate 32; the connecting stud 31 is used to connect to an external device and is combined with the fixing plate 32 by riveting and welding. The fixing plate 32 adopts... Figure 1The sheet-like structure shown has a circular hole in the center for the tail of the connecting stud 31 to pass through. The bottom of the fixing plate 32 has a pin that can pass through the through hole 16 at the bottom of the side wall and protrude externally. After the connecting stud 31 and the fixing plate 32 are combined, the plate body of the fixing plate 32 can be snapped into the slot 19 of the side wall, and the connecting stud 31 can be accommodated in the U-shaped opening 18 and protrude from the side wall of the base 11.

[0037] Furthermore, the connecting stud 31 and the fixing piece 32 are joined in the following manner. For example... Figure 5 As shown, the connecting stud 31 and the fixing plate 32 are placed sequentially in a pneumatic fixture. Driven by air pressure, the tail of the connecting stud 31 is riveted outward to form a folded edge 310. The riveted connecting stud 31 and the fixing plate 32 are then placed in a welding fixture, and laser welding is performed on the middle portions of both sides of the folded edge 310. The folded edge 310 melts in the welding area to form solder 311. The pneumatic fixture ensures the dimensional stability of the folded edge 310, and adjusting the pneumatic fixture controls the size of the folded edge 310 to better meet the impact resistance requirements of a drop. The size of the solder 311 formed by the melting of the folded edge 310 determines the torsional resistance of the connector 3. The size of the solder 311 can be adjusted by adjusting the laser welding parameters to better improve the torsional resistance after bonding.

[0038] As described above, the connector 3 ensures the impact resistance after connection through riveting, and laser welding enhances the torsional resistance after connection. Therefore, the audio equipment connection structure of this invention can improve the strength of the audio equipment connection port, enabling it to withstand various external forces such as pulling, impact, and torsion that may occur during stage performances, thereby ensuring the smooth operation of concerts and other performances and avoiding performance interruptions or sound quality degradation due to equipment failure.

[0039] like Figures 6 to 8 As shown, an optional embodiment of this utility model also provides a tensile testing device for detecting the tensile strength characteristics of the aforementioned audio device connection structure. This tensile testing device includes a first component 4, a second component 5, and two guide rods; the first component 4 and the second component 5 are connected to each other by a guide rod on both sides. The second component 5 is fixed to one end of each of the two guide rods, and the other end of each guide rod allows the first component 4 to be inserted. The first component 4 is constrained by the guide rods and can slide up and down along the two guide rods. Therefore, the guide rods ensure that the sliding pattern of the first component 4 and the second component 5 is consistent, preventing lateral deviation and ensuring stable test data.

[0040] The second component 5 has a groove 51 in the middle for the fixing piece 32 of the connector 3 to be inserted. Specifically, as shown in the figure... Figure 7As shown, a groove 510 is provided in the middle of the second component 5. A limiting piece 511 with a U-shaped opening is fixed to both sides of the groove 510 by screws on both sides. Here, the U-shaped opening of the limiting piece 511 and the groove 510 form a sliding groove 51. The fixing piece 32 of the connector 3 can be inserted along the open side of the U-shaped opening and stopped at the closed side of the U-shaped opening.

[0041] A nut 41 is provided in the middle of the first component 4. After the nut 41 slides up and down with the first component 4, it can be locked with the connecting stud 31 of the connector 3.

[0042] When using this tensile testing device, the fixing plate 32 of the connector 3 is inserted into the slide groove 51 of the second component 5, and the connecting stud 31 is locked to the nut 41 of the first component 4. Then, the tensile testing machine applies pressure to the first component 4 and the second component 5 of the tensile testing device respectively. By setting the parameters of the tensile testing machine, it can be detected whether the fixing plate 32 and the stud can meet the specified tensile requirements, thereby detecting the tensile strength characteristics of the connector 3.

[0043] like Figures 9 to 11 As shown, an optional embodiment of this utility model also provides a torque testing device for detecting the torsional resistance characteristics of the above-mentioned connection structure. The torque testing device includes opposing side structures, one side having a groove in the middle for inserting a fixing piece of the connector, and the other side having a groove in the middle for inserting a torque wrench or torque tester.

[0044] Specifically, the torque detection device includes a first body part 6 and a second body part 7; the first body part has a groove 611. A limiting member 610 is fixed to both sides of the groove 611 by nuts to form a sliding groove 61. The limiting member 610 has a U-shaped opening and is fixed to one side of the first body part 6, forming a sliding groove 61 between the U-shaped opening and the groove 611. The second body part 7 is a columnar structure, fixed to the other side of the first body part 6, and has a hexagonal groove 71 in the middle for connecting a torque wrench or torque meter.

[0045] When using this torque detection device, such as Figure 11 As shown, after the fixing piece 32 of the connector 3 is assembled into the slide groove 61 of the first body, the hexagonal groove at the bottom of the second body is inserted into the torque machine. The torque machine can be set to the maximum torque value. By turning the connecting stud 31 with a wrench, the torque resistance of the connector 3 can be tested to see if it meets the specified requirements, and thus the torque resistance characteristics of the connector 3 can be detected.

[0046] An optional embodiment of this utility model also provides a testing device, which includes the aforementioned tensile testing device and torsion testing device. The testing device can accurately detect the torsional and impact resistance of the port, ensuring the reliability of the equipment in actual use, thereby guaranteeing the smooth running of concerts, performances, and other events, and avoiding performance interruptions or sound quality degradation due to equipment failure.

[0047] An optional embodiment of this utility model provides a component for advanced audio equipment, which includes the above-described connection structure, tensile force detection device, and torque detection device.

[0048] In summary, the audio device connection structure provided by this utility model solves the problem that current audio devices cannot simultaneously withstand impact and torque through a combination of riveting and laser welding technology. By combining tensile and torque detection devices, impact and torsional data can be controlled, reducing usage risks and preventing equipment damage caused by improper operation and product drops during daily use, thus minimizing unnecessary economic losses for users.

[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model's technical solution.
