Description

Technical Field

[0001] The utility model relates to the technical field of sound overload protection devices, in particular to a sound overload protection device. Background Art

[0002] Speakers specifically refer to an audio system that is a combination of electrical equipment that produces sound. Speakers are usually damaged or burned out by overload current, so it is necessary to install an overload protector to protect them. When the protector detects that the current borne by the tweeter is too large and the received power exceeds the set threshold, such as the volume is suddenly too loud or there is howling, the protector starts working and limits the output electrical signal to share the overload current, allowing the tweeter to work normally without being affected by overload current, reducing the chance of voice coil burning out, and preventing overload damage.

[0003] When installing the speakers and protectors, the positive and negative connecting wires of the protector are usually directly connected to the positive and negative terminal posts of the tweeter on the speakers. The current wiring usually uses a threaded method, and the connecting wires are installed on the terminal posts by bolts. When the threads are installed, the threads are tightened, and one end of the threads is tightly pressed on the connector of the connecting wire, which can easily cause the connecting wire to deform and cause the protector connecting wire to become loose. Utility Model Content

[0006] The effect achieved by the above components is: connecting two connecting wires to the terminal posts respectively. When the protector detects that the current borne by the tweeter is too large and the received power exceeds the set threshold, the protector starts to work and will limit the output electrical signal to share the overload current, so that the tweeter can work normally without being affected by the overload current, reduce the probability of the voice coil burning out, and prevent overload damage. When wiring, insert the terminal ends of the two connecting wires into the two connecting grooves respectively, and then slide the limit rod downward so that one end of the limit rod and the inner wall of the connecting groove clamp the terminal ends of the connecting wire, thereby avoiding the current wiring usually using a threaded method, and the connecting wire is installed on the terminal post by a bolt. When the thread is installed, the bolt will be tightened, and one end of the bolt will be tightly pressed on the joint of the connecting wire, which can easily cause the connecting wire to deform and cause the protector connecting wire to loosen easily.

[0007] Preferably, sliding grooves are respectively provided on the inner walls on both sides of the connecting groove, sliding rods are slidably connected in the sliding grooves, and the two sliding rods are fixedly connected to the limiting rods.

[0008] The effect achieved by the above components is that the two slide bars slide in limited positions in the slide grooves, making the sliding process of the limit bars more stable.

[0009] Preferably, a first spring is fixedly connected to the slide rod, and one end of the first spring is fixedly connected to the inner wall of the slide groove.

[0010] The effect achieved by the above components is that when the limit rod clamps the connecting line, the first spring is in a contracted state, so the rebound elastic force of the first spring acts on the sliding rod, which can enhance the clamping effect on the connecting line.

[0011] Preferably, a fixing rod is fixedly connected to an inner wall on one side of the connecting groove, and a telescopic rod is fixedly connected to an inner wall on the other side of the connecting groove, and a clamping groove is respectively formed on the fixing rod and the telescopic rod.

[0012] The effect achieved by the above components is: the connecting wire is placed in the two slots, and the fixed rod and the telescopic rod can clamp and limit the connecting wire, so that the position of the connecting wire is more stable.

[0013] Preferably, a second spring is sleeved on the telescopic rod, one end of the second spring is fixedly connected to the telescopic rod, and the other end of the second spring is fixedly connected to the inner wall of the connecting groove.

[0014] The effect achieved by the above components is that when the fixed rod and the telescopic rod clamp the connecting wire, the second spring is in a contracted state, so the rebound elastic force of the second spring acts on the telescopic rod to enhance the limiting effect on the connecting wire.

[0015] Preferably, a mounting structure is provided on the tweeter, and the mounting structure is mainly composed of a mounting plate, and the mounting plate is fixedly connected to the tweeter. A sliding groove is opened on the mounting plate, and two sliding blocks are slidably connected in the sliding groove, and a clamping plate is fixedly connected to the sliding block.

[0016] The effect achieved by the above components is: placing the protector on the mounting plate and sliding the two sliding blocks can drive the two clamping plates to clamp the protector, so that the position of the protector is more stable.

[0017] Preferably, a bidirectional threaded rod is rotatably connected in the sliding groove, two sections of threads on the bidirectional threaded rod are in opposite directions, and the bidirectional threaded rod is threadedly connected to the sliding block.

[0018] The effect achieved by the above components is: since the sliding block slides within the sliding groove, rotating the bidirectional threaded rod will drive the two sliding blocks to slide, and since the two sections of the thread on the bidirectional threaded rod have opposite directions, rotating the bidirectional threaded rod will drive the two sliding blocks to move closer to or away from each other.

[0019] Preferably, a motor is fixedly connected to the mounting plate, an output shaft of the motor is fixedly connected to the bidirectional threaded rod, and a rubber pad is fixedly connected to the clamping plate.

[0020] The effects achieved by the above components are: starting the motor, the output shaft of the motor drives the bidirectional threaded rod to rotate, making the operation more convenient, the two rubber pads can strengthen the clamping effect of the protector, and prevent the rigid contact between the clamping plate and the protector from causing damage to the protector.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are that, in the utility model, by setting a connection structure, when wiring, the wiring ends of the two connecting wires are respectively inserted into the two connecting grooves, and then the limit rod is slid downward so that one end of the limit rod and the inner wall of the connecting groove clamp the wiring ends of the connecting wire, and the two slide bars slide in the slide groove with limited position, so that the sliding process of the limit rod is more stable. When the limit rod clamps the connecting wire, the first spring is in a contracted state, so the rebound elastic force of the first spring acts on the slide bar, which can enhance the clamping effect of the connecting wire and release the connecting wire. When the second spring is in a contracted state, the rebound force of the second spring acts on the telescopic rod to enhance the limiting effect of the connecting wire, thereby avoiding the situation that the current wiring usually uses a threaded method to install the connecting wire on the terminal post through a bolt, and the bolt will be tightened during the threaded installation, and one end of the bolt will be tightly pressed on the connector of the connecting wire, which may easily cause the connecting wire to deform and cause the protector connecting wire to loosen easily.

[0027] Embodiment 1, as Figure 1 As shown, an audio overload protection device includes a protector 1, a tweeter 2 is arranged on the protector 1, two connecting wires 3 are fixedly connected to the protector 1, and two binding posts 4 are fixedly connected to the tweeter 2.

[0028] Reference Figure 3, a connecting structure 5 is provided on the terminal 4, and the connecting structure 5 is mainly composed of a limit rod 51, which is slidably inserted on the terminal 4, and a connecting groove 52 is provided on the terminal 4, which connects the two connecting wires 3 and the terminal 4 respectively. When the protector 1 detects that the current borne by the tweeter 2 is too large and the received power exceeds the set threshold, the protector 1 starts to work, and will limit the output electrical signal to share the overload current, so that the tweeter 2 can work normally without being affected by the overload current, reduce the probability of burning the voice coil, and prevent overload damage. When wiring, plug the two connecting wires 3 into the terminals respectively. The two connecting grooves 52 are inserted, and then the limiting rod 51 is slid downward, so that one end of the limiting rod 51 and the inner wall of the connecting groove 52 clamp the wiring terminal of the connecting wire 3, thereby avoiding the current wiring usually using a threaded method, and the connecting wire 3 is installed on the terminal 4 by bolts. When the thread is installed, the bolt is tightened, and one end of the bolt is tightly pressed on the joint of the connecting wire 3, which is easy to cause the connecting wire 3 to be deformed, and the protector 1 The connecting wire 3 is easy to loosen. The inner walls of both sides of the connecting groove 52 are respectively provided with sliding grooves 53, and the sliding grooves 53 are slidably connected with sliding rods 54. The two sliding rods 54 and the limiting rods The first spring 55 is fixedly connected to the slide bar 54, and one end of the first spring 55 is fixedly connected to the inner wall of the slide groove 53. When the limit rod 51 clamps the connecting line 3, the first spring 55 is in a contracted state, so the rebound elastic force of the first spring 55 acts on the slide bar 54, which can strengthen the clamping effect of the connecting line 3. A fixed rod 56 is fixedly connected to the inner wall of one side of the connecting groove 52, and a telescopic rod 57 is fixedly connected to the inner wall of the other side of the connecting groove 52. The fixed rod 56 and the telescopic rod 57 are fixedly connected. The rod 57 is respectively provided with a clamping groove 59, and the connecting line 3 is placed in the two clamping grooves 59. The fixed rod 56 and the telescopic rod 57 can clamp and limit the connecting line 3, so that the position of the connecting line 3 is more stable. A second spring 58 is sleeved on the telescopic rod 57, and one end of the second spring 58 is fixedly connected to the telescopic rod 57, and the other end of the second spring 58 is fixedly connected to the inner wall of the connecting groove 52. When the fixed rod 56 and the telescopic rod 57 clamp the connecting line 3, the second spring 58 is in a contracted state, so the rebound elastic force of the second spring 58 acts on the telescopic rod 57, which can enhance the limiting effect on the connecting line 3.

[0029] Reference Figure 4The tweeter 2 is provided with a mounting structure 6, which is mainly composed of a mounting plate 61. The mounting plate 61 is fixedly connected to the tweeter 2. A sliding groove 62 is provided on the mounting plate 61. Two sliding blocks 63 are slidably connected in the sliding groove 62. A clamping plate 64 is fixedly connected to the sliding block 63. The protector 1 is placed on the mounting plate 61, and the two sliding blocks 63 are slid. The two clamping plates 64 can be driven to clamp the protector 1, so that the position of the protector 1 is more stable. A bidirectional threaded rod 65 is rotatably connected in the sliding groove 62. The two sections of the thread on the bidirectional threaded rod 65 are in opposite directions. The bidirectional threaded rod 65 is threadedly connected to the sliding block 63. Since the sliding block 63 is in the sliding The movable groove 62 is limited to slide, so rotating the two-way threaded rod 65 will drive the two sliding blocks 63 to slide, and because the two sections of the thread on the two-way threaded rod 65 are in opposite directions, rotating the two-way threaded rod 65 will drive the two sliding blocks 63 to move closer to or away from each other. A motor 66 is fixedly connected to the mounting plate 61, and the output shaft of the motor 66 is fixedly connected to the two-way threaded rod 65. A rubber pad 67 is fixedly connected to the clamping plate 64. When the motor 66 is started, the output shaft of the motor 66 drives the two-way threaded rod 65 to rotate, making the operation more convenient. The two rubber pads 67 can enhance the clamping effect of the protector 1 and prevent the rigid contact between the clamping plate 64 and the protector 1 from causing damage to the protector 1.

[0030] Working principle: connect two connecting wires 3 to the terminal 4 respectively. When the protector 1 detects that the current borne by the tweeter 2 is too large and the received power exceeds the set threshold, the protector 1 starts to work and limits the output electrical signal to share the overload current, so that the tweeter 2 can work normally without being affected by the overload current, reduce the probability of the voice coil burning, and prevent overload damage. When wiring, insert the wiring ends of the two connecting wires 3 into the two connecting grooves 52 respectively, and then slide the limit rod 51 downward so that one end of the limit rod 51 and the inner wall of the connecting groove 52 are aligned with the connecting wire 3. The connecting terminal is clamped, thereby avoiding the situation that the connecting wire 3 is installed on the terminal 4 by bolts in the current wiring method that usually uses threads. When the threads are installed, the bolts are tightened, and one end of the bolts is tightly pressed on the joint of the connecting wire 3, which is easy to cause the connecting wire 3 to deform, and the connecting wire 3 of the protector 1 is easy to loosen. The two slide bars 54 slide in the slide groove 53 to limit the sliding process of the limit rod 51, so that the sliding process of the limit rod 51 is more stable. When the limit rod 51 clamps the connecting wire 3, the first spring 55 is in a contracted state, so the rebound elastic force of the first spring 55 acts on the slide bar 54, can strengthen the clamping effect of the connecting line 3, put the connecting line 3 into the two card slots 59, the fixed rod 56 and the telescopic rod 57 can clamp and limit the connecting line 3, so that the position of the connecting line 3 is more stable, when the fixed rod 56 and the telescopic rod 57 clamp the connecting line 3, the second spring 58 is in a contracted state, so the rebound elastic force of the second spring 58 acts on the telescopic rod 57, which can strengthen the limiting effect of the connecting line 3, place the protector 1 on the mounting plate 61, slide the two sliding blocks 63, can drive the two clamping plates 64 to clamp the protector 1, so that the protector 1 The position of the protector 1 is more stable. Since the sliding block 63 slides in the sliding groove 62, rotating the bidirectional threaded rod 65 will drive the two sliding blocks 63 to slide. Since the two sections of the thread on the bidirectional threaded rod 65 are in opposite directions, rotating the bidirectional threaded rod 65 will drive the two sliding blocks 63 to move closer to or away from each other. The motor 66 is started, and the output shaft of the motor 66 drives the bidirectional threaded rod 65 to rotate, making the operation more convenient. The two rubber pads 67 can enhance the clamping effect of the protector 1 and prevent the rigid contact between the clamping plate 64 and the protector 1 from causing damage to the protector 1.
