Description

Technical Field

[0001] The utility model belongs to the technical field of wiring terminals, and in particular relates to a stable press-fit wiring terminal. Background Art

[0002] As an important component of circuit connection, the main function of the terminal block is to realize the convenient connection between the wire and the PCB board. When connecting the wire, the traditional terminal block usually needs to insert the wire into the hole of the terminal, fix it with screws or other fasteners, and then install the terminal block on the PCB board. Although this design meets the basic connection requirements to a certain extent, it exposes many shortcomings in practical applications.

[0003] First, the circuit connection requirements in different scenarios vary, including whether a ground wire is required, the number and specifications of wires, etc. However, existing terminal blocks often adopt a fixed design and are difficult to flexibly adapt to these changes. In actual applications, in order to meet specific connection requirements, users often need to make additional modifications or adjustments to the terminal blocks, which not only increases the workload and cost, but may also affect the stability and safety of the connection.

[0004] Secondly, existing terminal blocks usually use a simple mechanical clamping method to fix the wires. Although this fixing method can achieve the basic wire fixing function, due to its structural limitations, the fixing effect is not ideal. Under the influence of external factors such as vibration and temperature changes, the wires are prone to loosening or falling off, causing circuit failures.

[0005] In addition, the existing terminal blocks often lack an effective fixing mechanism after being plugged into the PCB board. This causes the terminal blocks to easily slide on the PCB board, which can easily lead to poor solder joints, cold solder joints and other undesirable conditions during the soldering process. These problems not only affect the connection quality of the circuit, but may also have an adverse effect on the performance and stability of the entire circuit system.

[0006] Therefore, it is very necessary to invent a stable press-fit terminal. Utility Model Content

[0010] Furthermore, the inner wall of the terminal box and the lower side of the pressure plate are both provided with a plurality of protrusions, wherein the protrusions are hemispherical in shape. Such a configuration can improve the fixing effect of the wires.

[0011] Furthermore, the fixing frame includes a support plate, a column and a wrapping plate, one end of the support plate is fixed to the first shell or the second shell, and the upper side of the support plate is fixed with the column by welding; the upper end of the column is fixed with the wrapping plate by welding, wherein the wrapping plate and the support plate are arranged perpendicular to each other, such an arrangement can prevent the wire from being detached inside the pressing frame when an external force is applied.
