Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, and in particular to a precision power terminal for vehicle loudspeakers. Background Technology

[0002] A car speaker is a transducer that converts electrical signals into sound signals. The performance of a speaker has a great impact on sound quality. The speaker is the weakest component in an audio system, yet it is also the most important component for sound effects.

[0003] However, the terminal structures used in existing car speakers are mostly fixed to one side of the speaker by soldering. During the use of the speaker, it may need to be adjusted many times. In this process, frequent wiring may occur and the terminals may break. Therefore, this does not meet the current requirements. To address this, we propose a precision power terminal for car speakers. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, one of the objectives of this utility model is to provide a precision power terminal for vehicle speakers.

[0005] One of the objectives of this utility model is achieved through the following technical solution: A precision power terminal for a vehicle speaker includes a metal terminal piece with four circular holes. A metal connecting tube is movably inserted through the inner cavity of two of the circular holes. An elastic limiting rod is provided on the rear side of the metal connecting tube. Slots are provided on both the left and right sides of the metal connecting tube. Two stops are fixedly connected to the left and right sides of the inner cavity of the elastic limiting rod. The two ends of the elastic limiting rod movably pass through adjacent slots.

[0006] Furthermore, a square cone buckle is fixedly connected to the top of the metal terminal piece, and the square cone buckle is located near the center of the metal terminal piece.

[0007] Furthermore, a connector is fixedly connected to the front side of the metal connecting tube, and the connector is located near the bottom of the metal connecting tube.

[0008] Furthermore, the connector has a wire hole located near the front side of the connector.

[0009] Furthermore, the cross-section of the elastic limiting rod is U-shaped, and the opening of the U-shaped structure of the elastic limiting rod faces forward.

[0010] Furthermore, a limiting block is fixedly connected to the bottom of the elastic limiting rod, and four limiting grooves are opened on the top of the metal terminal piece near the rear side. The limiting block is slidably connected to the inner cavity of the adjacent limiting groove.

[0011] Furthermore, the side of the stop block closest to the metal connecting pipe has an arc-shaped surface, which fits against the outer wall of the metal connecting pipe, and the side of the stop block away from the metal connecting pipe has an inclined surface.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model discloses a precision power terminal for a vehicle-mounted speaker. When the metal connecting tube and the terminal piece of this device are assembled on the metal terminal piece, the metal connecting tube is simply passed through the bottom of the round hole, and then the elastic limiting rod is moved until the two front blocks move to the front of the metal connecting tube. At this time, the movement of the elastic limiting rod is stopped, and the four blocks limit the metal connecting tube. The two sides of the elastic limiting rod are inserted into the inner cavity of the two slots to fix the metal connecting tube. The assembly method replaces the traditional soldering method, which is convenient for circuit debugging and avoids the occurrence of breakage and reconnection later. 2. This utility model provides a precision power terminal for a vehicle-mounted speaker. The limiting block moves with the elastic limiting rod to the inner cavity of the adjacent limiting groove. The setting of the limiting block and the limiting groove can prevent the elastic limiting rod from displacing in the horizontal left and right directions, thereby improving the stability of the metal connecting tube and preventing the metal connecting tube from detaching from the metal terminal piece, thus avoiding circuit breakage.

In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example

[0019] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 A precision power terminal for a vehicle speaker includes a metal terminal piece 1. A square cone buckle 2 is fixedly connected to the top of the metal terminal piece 1. The square cone buckle 2 is located near the center of the metal terminal piece 1. The metal terminal piece 1 can be connected and fixed to the speaker frame through the square cone buckle 2. The metal terminal piece 1 has four round holes 3. A metal connecting tube 4 is movably inserted through the inner cavity of two of the round holes 3. A wiring piece 5 is fixedly connected to the front side of the metal connecting tube 4. The wiring piece 5 is located near the bottom of the metal connecting tube 4. A wire hole 6 is opened on the wiring piece 5. The wire hole 6 is located near the front side of the wiring piece 5.

[0020] The metal connecting pipe 4 is provided with an elastic limiting rod 7 on its rear side. The cross-section of the elastic limiting rod 7 is U-shaped, and the opening of the U-shaped structure of the elastic limiting rod 7 faces forward. The left and right sides of the metal connecting pipe 4 are provided with slots 10. The inner cavity of the elastic limiting rod 7 is fixedly connected to two blocks 11 on the left and right sides. The two ends of the elastic limiting rod 7 can move through the adjacent slots 10. The side of the block 11 close to the metal connecting pipe 4 is provided with an arc-shaped surface. The arc-shaped surface of the block 11 fits against the outer wall of the metal connecting pipe 4. The side of the block 11 away from the metal connecting pipe 4 is provided with a slope.

[0021] In the above embodiment, when it is necessary to install the metal connecting pipe 4, the metal connecting pipe 4 is passed through the bottom of the round hole 3, and then the elastic limiting rod 7 is moved. The elastic limiting rod 7 moves to the rear side of the metal connecting pipe 4 and aligns with the two slots 10. Then, the elastic limiting rod 7 is moved forward. Under the action of the inclined surface of the stop block 11, the elastic limiting rod 7 expands outward on both sides until the two stop blocks 11 on the front side move to the front side of the metal connecting pipe 4. At this time, the movement of the elastic limiting rod 7 is stopped, and the four stop blocks 11 hold the metal connecting pipe 4 in place. The metal connecting tube 4 is limited, and the elastic limiting rod 7 is inserted into the inner cavity of the two slots 10 on both sides to fix the metal connecting tube 4. At the same time, the limiting block 8 moves with the elastic limiting rod 7 to the inner cavity of the adjacent limiting groove 9. The setting of the limiting block 8 and the limiting groove 9 can prevent the elastic limiting rod 7 from displacing in the horizontal left and right directions, thereby improving the stability of the metal connecting tube 4 and preventing the metal connecting tube 4 from detaching from the metal terminal piece 1, thereby preventing the circuit from being broken. Then, wires are connected to the two wire holes 6 to realize the conduction of current. Example

[0022] Please see Figure 3 and Figure 7 A precision power terminal for a vehicle speaker, wherein a limiting block 8 is fixedly connected to the bottom of an elastic limiting rod 7, and four limiting grooves 9 are provided on the top of a metal terminal piece 1 near the rear side, and the limiting block 8 is slidably connected to the inner cavity of an adjacent limiting groove 9.

[0023] In the above embodiment, during use, the limiting block 8 moves with the elastic limiting rod 7 to the inner cavity of the adjacent limiting groove 9. The setting of the limiting block 8 and the limiting groove 9 can prevent the elastic limiting rod 7 from displacing in the horizontal left and right directions, thereby improving the stability of the metal connecting pipe 4 and preventing the metal connecting pipe 4 from detaching from the metal terminal piece 1, thereby preventing circuit breakage.

[0024] Working principle: This utility model is a precision power terminal for a vehicle speaker. The metal terminal piece 1 can be connected and fixed to the speaker frame through the square cone buckle 2. The two round holes 3 near the outermost part of the metal terminal piece 1 are used for power line connection, while the two round holes 3 in the middle are used for frequency division operation.

[0025] When it is necessary to install the metal connecting tube 4, pass the metal connecting tube 4 through the bottom of the round hole 3, and then move the elastic limiting rod 7. The elastic limiting rod 7 moves to the rear side of the metal connecting tube 4 and aligns with the two slots 10. Then move the elastic limiting rod 7 forward. Under the action of the inclined surface of the stop block 11, the elastic limiting rod 7 expands outward on both sides until the two stop blocks 11 move to the front side of the metal connecting tube 4. At this time, stop moving the elastic limiting rod 7. The four stop blocks 11 limit the metal connecting tube 4, and the elastic limiting rod 7 is inserted into the inner cavity of the two slots 10 on both sides, thereby fixing the metal connecting tube 4. At the same time, the limiting block 8 moves with the elastic limiting rod 7 to the inner cavity of the adjacent limiting groove 9. The setting of the limiting block 8 and the limiting groove 9 can prevent the elastic limiting rod 7 from displacing in the horizontal left and right directions, thereby improving the stability of the metal connecting tube 4 and preventing the metal connecting tube 4 from detaching from the metal terminal piece 1, thereby preventing circuit breakage.

[0026] Then, wires are connected to the two wire holes 6 to conduct current.

[0027] When the metal connecting tube 4 and the terminal block 5 of the device are assembled on the metal terminal block 1, simply pass the metal connecting tube 4 through the bottom of the round hole 3, and then move the elastic limiting rod 7 until the two front stops 11 move to the front of the metal connecting tube 4. At this time, stop moving the elastic limiting rod 7. The four stops 11 limit the metal connecting tube 4, and the two sides of the elastic limiting rod 7 are inserted into the inner cavity of the two slots 10 to fix the metal connecting tube 4. The assembly method replaces the traditional soldering method, which is convenient for circuit debugging and avoids the occurrence of breakage and reconnection later.
