Description

Technical Field

[0001] This application relates to the technical field of terminal blocks, and in particular to a terminal block for a MINI type automotive amplifier. Background Technology

[0002] The MINI-type car amplifier terminal block is an interface component used in electronic devices to connect wires, and it is used in the MINI-type car feature phone.

[0003] One type of power amplifier terminal block in the related technology includes a housing and a terminal block, wherein the terminal block is inserted into a mounting slot on the housing.

[0004] There is a gap between the existing wiring terminals and the inner wall of the mounting groove. When the vehicle is traveling on bumpy roads, the wiring terminals may move and collide with the housing, causing damage to the wiring terminals. Utility Model Content

[0005] To prevent damage to the wiring terminals, this application provides a MINI-type automotive amplifier wiring terminal.

[0006] This application provides a MINI-type automotive amplifier terminal block, which adopts the following technical solution:

[0007] A MINI-type car amplifier terminal block includes a housing with a mounting groove on one side and a socket on the bottom wall of the mounting groove. A terminal block is assembled in the mounting groove, and the terminal block includes a wiring portion that can be inserted into the mounting groove. The wiring portion has a slot aligned with the socket on the side facing the socket. The two opposite sides of the wiring portion are both flat and parallel to each other. Each of the two flat surfaces is in contact with the horizontal inner wall of the mounting groove. The upper end of the wiring portion is provided with a first protrusion that is in contact with the upper inner wall of the mounting groove, and the lower end of the wiring portion is provided with a second protrusion that is in contact with the lower inner wall of the mounting groove.

[0008] By adopting the above technical solution, the terminal block is inserted into the mounting groove. The two planes prevent the terminal block from swinging horizontally along the axis of the mounting groove. The first protrusion fits against the upper inner wall of the mounting groove, preventing the terminal block from swinging upward. The second protrusion fits against the lower inner wall of the mounting groove, preventing the terminal block from swinging downward. This makes it difficult for the terminal block to move in the mounting groove, improving the stability of the terminal block in the mounting groove. Under the condition of vehicle bumps, it avoids collision damage to the terminal block and extends the service life of the terminal block.

[0009] Optionally, the diameter of the socket gradually decreases towards the mounting groove.

[0010] By adopting the above technical solution, a guiding function is provided, making it easier for workers to pass the wire through the socket and insert it into the slot.

[0011] Optionally, the opening edge of the slot is chamfered.

[0012] By adopting the above technical solution, the chamfer has a guiding function, making it easier for workers to pass the wire through the socket and insert it into the slot.

[0013] Optionally, an operating tube is provided above the wiring part, and an operating hole communicating with the inside of the operating tube is provided on the inner wall of the slot. A bolt that can be inserted into the slot is threaded into the operating tube, and an installation hole that allows the bolt to pass through is provided on the housing.

[0014] By adopting the above technical solution, after the wire is inserted into the slot, the bolt passes through the mounting hole and is threaded into the operating tube. The bolt is then driven to rotate, causing it to clamp the wire against the inner wall of the slot. In addition, after the bolt is installed on the terminal block, part of the bolt is in the mounting hole. As the terminal block moves away from the socket, it is restricted by the bolt and the inner wall of the mounting hole, making it difficult to pull the terminal block out of the mounting slot.

[0015] Optionally, a transition portion is provided at the end of the wiring portion away from the bottom wall of the mounting groove, and a pin portion is provided at the bottom of the transition portion.

[0016] By adopting the above technical solution, the terminal block can be connected to the circuit board using the pin section.

[0017] Optionally, the pin portion is cylindrical.

[0018] By adopting the above technical solution, the cylindrical pin portion is easier to assemble and solder with the circuit board, enabling the terminal block to withstand a larger current intensity during use.

[0019] Optionally, multiple mounting slots and wiring terminals are provided along the length of the housing.

[0020] By adopting the above technical solution, the number of terminal blocks can be increased, enabling electrical connections for more electrical components.

[0021] Optionally, the bottom wall of the housing is provided with a fixing tube and a reinforcing plate, and the reinforcing plate is fixedly connected to the outer circumferential surface of the fixing tube.

[0022] By adopting the above technical solution, the connection strength between the fixing tube and the shell can be improved with the help of the reinforcing plate, and the shell can be connected and installed with other objects with the help of the fixing tube.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The terminal block is inserted into the mounting groove. The two flat surfaces prevent the terminal block from swinging horizontally along the axis of the mounting groove. The first protrusion fits against the upper inner wall of the mounting groove, preventing the terminal block from swinging upward. The second protrusion fits against the lower inner wall of the mounting groove, preventing the terminal block from swinging downward. This makes the terminal block less likely to move in the mounting groove, improving the stability of the terminal block in the mounting groove. Under the condition of vehicle bumps, it avoids the terminal block being damaged by collision and extends the service life of the terminal block.

[0025] 2. The cylindrical pins are assembled and soldered to the circuit board, enabling the terminals to withstand a large current intensity during use. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This embodiment discloses a terminal block for a MINI-type automotive amplifier. (Refer to...) Figure 1 A MINI-type car amplifier terminal block includes a housing 1 and a terminal block 2.

[0034] Reference Figure 2The housing 1 is made of plastic. Several mounting grooves 11 are provided on one side of the housing 1, and these mounting grooves 11 are arranged in an array along the length of the housing 1. Furthermore, clamping strips 12 are integrally formed on both horizontal inner walls of the mounting grooves 11. The clamping strips 12 are deformable, and their length direction is consistent with the axial direction of the mounting grooves 11.

[0035] Reference Figure 2 and Figure 3 The housing 1 has several insertion holes 13 on the side away from the mounting slot 11, and these insertion holes 13 are arranged in an array along the length of the housing 1. The number of insertion holes 13 is the same as the number of mounting slots 11. Each insertion hole 13 communicates with one mounting slot 11. The opening of the insertion hole 13 gradually decreases in size as it approaches the mounting slot 11. Power cables can pass through the insertion holes 13.

[0036] Reference Figure 2 and Figure 3 The upper surface of the housing 1 has a plurality of mounting holes 14, which are arranged in an array along the length of the housing 1. The number of mounting holes 14 is the same as the number of mounting slots 11. Each mounting hole 14 communicates with a mounting slot 11.

[0037] Reference Figure 2 and Figure 3 Two fixed tubes 15 are fixedly connected to the bottom of the housing 1, and the two fixed tubes 15 are arranged in an array along the length of the housing 1. A reinforcing plate 16 is fixedly connected to the outer circumferential surface of the fixed tubes 15, and the upper end of the reinforcing plate 16 is fixedly connected to the housing 1.

[0038] Reference Figure 1 and Figure 4 The terminal blocks 2 are made of conductive metal. Several terminal blocks 2 are provided, the number of which is the same as the number of mounting slots 11. Each terminal block 2 is assembled into its own mounting slot 11.

[0039] Reference Figure 3 and Figure 4 The terminal block 2 includes an integrally formed wiring portion 21, a transition portion 22, and a pin portion 23. The wiring portion 21 can be inserted into the mounting groove 11. A slot 211 is provided at the end of the wiring portion 21 facing the socket 13, and a chamfer 212 is provided along the opening edge of the slot 211, allowing a power cable to be inserted. Both ends of the wiring portion 21 along the length of the housing 1 are both flat surfaces 213, and the two flat surfaces 213 are parallel to each other. When the wiring portion 21 is inserted into the mounting groove 11, each of the two flat surfaces 213 is in contact with the horizontal inner wall of the mounting groove 11. If the flat surface 213 abuts against the clamping strip 12, the clamping strip 12 deforms to clamp the wiring portion 21, making it difficult for the wiring portion 21 to detach from the mounting groove 11.

[0040] Reference Figure 1 and Figure 4 An operating tube 24 is fixedly connected to the upper part of the wiring section 21. An operating hole is formed on the inner wall of the slot 211, communicating with the interior of the operating tube 24. The inner diameter of the operating hole is the same as the inner diameter of the operating tube 24. When the wiring section 21 abuts against the bottom wall of the mounting groove 11, the operating tube 24 aligns with the mounting hole 14. A screw 27 is threaded into the operating tube 24, allowing it to pass through the operating hole and be inserted into the slot 211.

[0041] Reference Figure 1 and Figure 4 The transition portion 22 is located on the side of the wiring portion 21 away from the socket 13. The pin portion 23 is cylindrical and is located below the transition portion 22.

[0042] Reference Figure 1 and Figure 4 The upper end of the wiring part 21 is fixedly connected to a first protrusion 25, and the end of the first protrusion 25 near the socket 13 is fixedly connected to the operating tube 24. The lower end of the wiring part 21 is fixedly connected to a second protrusion 26, and the end of the second protrusion 26 away from the socket 13 is fixedly connected to the operating tube 24.

[0043] Reference Figure 1 and Figure 4 When the terminal 2 is inserted into the mounting groove 11, the end face of the first protrusion 25 away from the wiring part 21 is in contact with the upper inner wall of the mounting groove 11, and the end face of the second protrusion 26 away from the wiring part 21 is in contact with the lower inner wall of the mounting groove 11.

[0044] The implementation principle of a MINI-type car amplifier terminal block in this application embodiment is as follows: by means of the two planes 213, the first protrusion 25 and the second protrusion 26 of the terminal block 2, all four end faces of the mounting groove 11 are in contact with the terminal block 2, so that the terminal block 2 is not easy to swing in the mounting groove 11.
