Description

Technical Field

[0001] This utility model relates to the field of thyristor circuit technology, and in particular to a thyristor module with intermediate trigger sustain lead-out. Background Technology

[0002] Traditional rectifier circuits include two types: thyristor rectifiers and semiconductor rectifiers. Semiconductor rectifiers rely on the unidirectional conduction characteristic of the PN junction and cannot regulate the output current. Thyristor rectifiers, on the other hand, have adjustable output current. By controlling the gate (G) of the thyristor, the on / off ratio and frequency of the thyristor can be controlled, thus rectifying the AC power in the circuit and controlling the current magnitude. Thyristor rectifiers typically have terminals that work with the motor to achieve input and output, as shown in patent CN219329255U. However, in practical use, the connection stability of the terminals decreases significantly with repeated insertions and removals; furthermore, the complex structure of the terminals increases assembly difficulty and production costs. Therefore, a thyristor module with a stable connection and simple structure and intermediate trigger sustain lead is needed. Summary of the Invention

[0017] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0018] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the figures only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0019] Example 1: like Figures 1-3As shown, a thyristor module with intermediate trigger sustaining output includes a thyristor structure 1, a housing 2 for placing the thyristor circuit board 12, and a cover 3 covering the housing 2 and detachably connected to the housing 2; wherein the thyristor structure 1 includes a base plate 11 and a circuit board 12, the circuit board 12 being fixed on the base plate 11; the base plate 11 is fixedly installed on the bottom of the housing 2, which has vertical penetration, and the top of the housing 2 is also fixedly connected to the cover 3; it also includes a first electrode 4, a second electrode 5, and a mounting base 6; the mounting base 6 is fixedly installed on the bottom of the housing 2, which has vertical penetration, the top of the housing 2, and the cover 3; it also includes a first electrode 4, a second electrode 5, and a mounting base 6; the mounting base 6 is fixedly installed on the bottom of the housing 2, the top of the housing 2, and the cover 3. The first electrode 4 is fixedly positioned in the middle of the housing 2. The mounting base 6 has a insertion hole 61 for inserting the first electrode 4, with the opening of the insertion hole 61 facing the cover 3. The first electrode 4 is inserted into the insertion hole 61. One end of the first electrode 4 located in the insertion hole 61 is connected to the circuit board 12 via a wiring connection. The other end of the first electrode 4 passes through the cover 3 and is exposed on the upper surface of the cover 3. One end of the second electrode 5 is directly connected to the circuit board 12, and the other end of the second electrode 5 passes through the cover 3 and is exposed on the upper surface of the cover 3. Both the first electrode 4 and the second electrode 5 are made of metal electrode sheets of a certain thickness, which have relatively stable performance and will not deform or be damaged with increasing insertion and removal cycles. Furthermore, the first electrode 4 is directly connected to the mounting base 6 inside the housing 2. In this example, the mounting base 6 and the housing 2 are integrally formed, resulting in a simple overall structure and low mold cost.

[0020] The housing 2 is generally square and box-shaped. Both the top and bottom of the housing 2 are open, allowing the two ends to pass through. The top end of the housing 2 is snapped into the cover 3. The bottom of the cover 3 is provided with a downwardly extending skirt for embedding into the interior of the housing 2 and fitting against the inner wall of the housing 2. The bottom end of the housing 2 is snapped into the base plate 11 in the thyristor structure 1. The base plate 11 is embedded in the inner side of the bottom of the housing 2, and the edge of the base plate 11 abuts against the inner wall of the housing 2. The circuit board 12 on the base plate 11 is located inside the housing 2. A mounting base 6 is fixedly installed in the middle part of the interior of the housing 2.

[0021] The housing 2 has threaded mounting holes 21 at both ends of its length for threaded connection with the base plate 11. It should be noted that the parts of the housing 2 with threaded mounting holes 21 are recessed into the housing 2. On the one hand, this allows the base plate 11 to abut against the threaded mounting holes 21 when it is embedded in the bottom of the housing 2, thus avoiding excessive insertion into the housing 2. On the other hand, it facilitates the use of screws to achieve a fixed connection between the base plate 11 and the housing 2.

[0022] A gap is left between the bottom of the slot 62 and the bottom of the insertion hole 61 for accommodating the wiring of the first electrode 4. Additionally, one or both sides of the insertion hole 61 on the mounting base 6 have openings that penetrate the mounting base 6. In this example, one side of the insertion hole 61 has an opening to facilitate connection between the wiring located at the bottom of the first electrode 4 and the circuit board 12 below, preventing the wiring from coming out of the opening above the insertion hole 61. The insertion hole 61 on the mounting base 6 also has a vertical slot 62 that matches the first electrode 4. The first electrode 4 is embedded in the slot 62, ensuring the stability of the connection between the first electrode 4 and the mounting base 6. In this example, the slot is located on the inner wall of the insertion hole, recessed into its inner wall to form a groove structure.

[0023] The insertion hole 61 contains two slots 62; the mounting base 6 has two insertion holes 61, corresponding to the two gates and two cathodes of the two thyristors respectively; and the two second electrodes 5 correspond to the two anodes of the two thyristors. The parts of the cover 3 through which the first electrode 4 and the second electrode 5 protrude are respectively marked with corresponding electrode markings 31.

[0024] The portion of the second electrode 5 that protrudes from the cover 3 is bent at a right angle, and the bent portion fits against the upper surface of the cover 3; the bent portion of the second electrode 5 is provided with a through hole, and a nut 32 is provided on the cover 3 corresponding to the through hole of the bent portion, so as to facilitate connection with an external load.

[0025] During implementation, by setting the first electrode 4 and the second electrode 5 to be directly connected to the external power supply and load respectively, the connection is stable and the structure is simple, reducing production costs. By setting a lateral opening on the mounting base 6, and matching the gap between the bottom of the slot 62 and the insertion hole 61, it is convenient to bring out the wiring at the bottom of the first electrode 4 to achieve connection with the circuit board 12. By setting the electrode mark 31 corresponding to the electrode on the cover 3, it is convenient to perform external wiring and avoid incorrect wiring.

[0026] Example 2: like Figure 4 , Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that both the first and second electrodes are directly soldered to the circuit board on the base plate. The other ends of the first and second electrodes protrude from the cover and connect to external electrical equipment or power sources. It should be noted that in this example, the cover and housing are integrally formed. Because both the first and second electrodes are fixed to the circuit board, no additional installation is required. Therefore, there is no need to set up a structure in the middle of the housing to fix the first electrode. Thus, the cover and housing can be integrally formed during injection molding, saving processes and costs, and facilitating installation. The second electrode is bent after protruding from the cover, close to the nut provided on the cover.

[0027] During implementation, the first and second electrodes are directly welded and fixed to the circuit board. The other end of the electrode passes through the through hole on the cover for positioning, thereby fixing the electrode and facilitating connection with external electrical equipment and power supply. At the same time, the structure is simple, the cost is low, and the assembly is convenient.

[0028] The above description is merely a specific example of this utility model and does not constitute any limitation on this utility model. Obviously, those skilled in the art, after understanding the content and principle of this utility model, may make various modifications and changes in form and details without departing from the principle and structure of this utility model. However, these modifications and changes based on the concept of this utility model are still within the protection scope of the claims of this utility model.
