Description

[0002] In the prior art, the pin positions of resistors used in working circuits are usually fixed, and the relative position between the two pins cannot be adjusted according to the actual situation of the working circuit. This fixed pin design has many limitations in practical applications: when the resistor needs to adapt to circuit boards with different layouts or connect to working circuits of different specifications, the positions of the two pins are often difficult to meet the circuit wiring requirements, and the operator has to re-solder the pins to adapt to the wiring requirements, which not only increases the workload of installation and debugging, but may also cause pin damage or reduced reliability of soldering points due to repeated soldering. For some circuits that have special requirements for pin positions, it is even necessary to replace resistors of other models and specifications, which undoubtedly increases the cost of circuit design. In addition, in a high-density integrated circuit board environment, resistors with fixed pins may interfere with surrounding electronic components due to the inability to flexibly adjust the pin position, affecting the compactness and rationality of the overall circuit layout, thereby restricting the flexibility and adaptability of circuit design.

DETAILED DESCRIPTION

[0034] The technical solutions of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments of the present invention and the features therein may be combined with each other unless there is a conflict.

[0035] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0036] See also Figures 1 to 7 The present invention provides a resistor 100 with adjustable pin positions. The resistor 100 includes a first conductive portion 10 having a first pin 12 and a second conductive portion 20 having a second pin 22. The structural design of the resistor 100 allows for an adjustable angle between the lead-out directions of the first pin 12 and the second pin 22, thereby adapting to the actual needs of different operating circuits.

[0037] Specifically, see Figure 1 and Figure 2 The resistor 100 includes a first conductive portion 10, a second conductive portion 20, a rotating shaft structure 30, and a locking structure 40. The first conductive portion 10 includes a first disk 11 and a first pin 12, which extends radially outward from the inner periphery of the first disk 11 to the outer periphery of the first disk 11. The second conductive portion 20 is spaced apart from the first conductive portion 10 in the axial direction. The second conductive portion 20 includes a second disk 21 and a second pin 22, which extends radially outward from the inner periphery of the second disk 21 to the outer periphery of the second disk 21. Preferably, the second pin 22 extends radially along the second disk 21.

[0038] The material of the first conductive portion 10 and the second conductive portion 20 is generally a material with good electrical conductivity such as brass or copper. The connection and fixing method between the first pin 12 and the first disk body 11, and the second pin 22 and the second disk body 21 is not limited. For example, they can be set as a whole, or welded, or screwed. The extension direction of the first pin 12 and the second pin 22 can be designed as needed. In this embodiment, it is preferred that the axial projections of the first disk body 11 and the second disk body 21 are both perfect circular disks, and the first pin 12 is connected to the outer periphery of the first disk body 11 and extends outward in the radial direction of the first disk body 11. The second pin 22 is connected to the outer periphery of the second disk body 21 and extends outward in the radial direction of the second disk body 21.

[0039] The rotating shaft structure 30 is connected between the first plate 11 and the second plate 21 so that the first plate 11 and the second plate 21 can be connected to each other in a relatively rotatable manner. Figure 3 As shown, the rotating shaft structure 30 includes a shaft body 31, a sleeve body 32 and an insulating ring 33. The shaft body 31 extends axially, and one end is passed through the first disk body 11, and the other end is fixed to the second disk body 21. The sleeve body 32 is sleeved on the outer periphery of the shaft body 31, and is arranged on the side of the first disk body 11 away from the second disk body 21. The sleeve body 32 includes a resistance ring 321, which is generally made of alloy resistance material. The insulating ring 33 is arranged between the shaft body 31 and the sleeve body 32, and between the shaft body 31 and the first disk body 11, so that the currents flowing through the shaft body 31 and the resistance ring 321 are in opposite directions.

[0040] Specifically, the shaft 31 can be made of a conductive material such as brass or copper, and the sleeve 32 can be made of a strong and insulating material such as ceramic. The sleeve 32 is at least partially provided with the above-mentioned resistance ring 321 in the axial direction, and the other parts can also be provided with a conductive material such as brass or copper. The insulating ring 33 is at least sandwiched between the shaft 31 and the first disk 11, and extends to the vicinity of the end of the sleeve 32 that is away from the first disk 11 in the axial direction. In this way, in one embodiment, the current can be along Figure 2 The current flows in the direction indicated by the dotted arrow, specifically, from the second pin 22 to the second disk 21, and then flows axially upward through the shaft 31 to the end where the shaft 31 contacts the sleeve 32, and then flows axially downward through the resistor ring 321, and flows through the sleeve 32 to the first disk 11, and then is led out from the first pin 12. It should be noted that in other embodiments, the direction of the current can also be different from Figure 2 The directions shown are opposite.

[0041] In this embodiment, the insulating ring 33, shaft 31, and sleeve 32 are fixed together to form the rotating shaft structure 30. The shaft 31 is fixed to the second disk 21, and the second disk 21 is relatively rotatably sleeved on the outer circumference of the insulating ring 33, thereby enabling relative rotation between the first disk 11 and the second disk 21. When the first disk 11 and the second disk 21 are relatively locked by the locking structure 40, the sleeve 32 is axially pressed against the first disk 11 to ensure electrical connection between the two. When the first disk 11 and the second disk 21 need to be operated to allow relative rotation between them, the sleeve 32 can be loosely fitted with the first disk 11, allowing the first disk 11 to be rotated and adjusted relative to the rotating shaft structure 30 and the second disk 21.

[0042] In this embodiment, the coordinated design of the shaft 31, sleeve 32, and insulating ring 33 within the rotating shaft structure 30 ensures smooth relative rotation between the first and second disks 11 and 21. The insulating ring 33 also ensures that the currents in the shaft 31 and the resistor ring 321 flow in opposite directions, forming a coaxial current conduction structure. This design allows the magnetic fields generated by the current flowing through the resistor ring 321 to cancel each other out, reducing magnetic field interference and thereby improving the measurement accuracy and stability of the resistor 100 within the circuit.

[0043] The locking structure 40 and the rotating shaft structure 30 are spaced apart in the radial direction. Please continue to refer to Figure 4 The locking structure 40 includes a first locking portion 41 provided on the first disk 11 and a plurality of second locking portions 42 provided on the second disk 21. The plurality of second locking portions 42 are spaced apart circumferentially on the second disk 21. The first locking portion 41 can selectively engage with one of the plurality of second locking portions 42 to limit the relative rotational travel between the first disk 11 and the second disk 21. The specific structures of the first locking portion 41 and the second locking portion 42 are not limited, as long as the locking structure 40 can achieve relative fixation between the first disk 11 and the second disk 21 after adjusting their relative positions according to actual needs. It is understood that the locking structure 40 should be made of an insulating material such as plastic to prevent a short circuit between the first conductive portion 10 and the second conductive portion 20.

[0044] It will be appreciated that when both the first disk 11 and the second disk 21 are configured as true circular disks, the locking structure 40 can be positioned at their respective centers. This allows the axial projection of the outer contour to remain unchanged during relative rotational adjustment. This disc-shaped design not only allows for more uniform current flow through the rotating shaft structure 30, improving the measurement accuracy and stability of the resistor 100, but also allows for arbitrary adjustment of the circumferential rotational position of the resistor 100 when installed in a circuit structure without altering the general outer contour or footprint of the resistor 100, enabling greater flexibility in adapting to the installation space of different operating circuits.

[0045] In this embodiment, the first conductive portion 10 and the second conductive portion 20 are provided, and the shaft structure 30 is used to realize the relative rotation connection between the two. At the same time, the first pin 12 and the second pin 22 are fixed at the desired relative position by the locking structure 40, so that the lead-out direction of the first pin 12 and the second pin 22 can be flexibly adjusted according to the actual circuit requirements, such as Figure 1 、 Figure 5 and Figure 7 As shown, the first pin 12 and the second pin 22 can be adjusted to different positions, such as the same lead-out direction, opposite lead-out directions, or a lead-out direction at an angle less than 90 degrees. This effectively solves the poor adaptability problem caused by the fixed pin positions of the existing resistor 100, significantly improving the versatility and applicability of the resistor 100. When the above-mentioned resistor 100 is installed in different working circuits, there is no need to re-solder the pins of the resistor 100 or change the model, which reduces the cost of circuit design and debugging, while facilitating the compact layout and flexible wiring of the circuit board, effectively improving the efficiency and reliability of circuit installation.

[0046] like Figure 3 As shown, the shaft 31 of the resistor 100 preferably includes an insulating column 311 and a guide column 312 sleeved around the insulating column 311. The sleeve 32 sleeves around the guide column 312. The insulating column 311 can be made of an insulating material such as ceramic to provide electrical isolation and prevent excessive current in the guide column 312 from causing arcing. The guide column 312 can be made of a material with excellent electrical conductivity, such as brass or copper, to transmit current.

[0047] Specifically, the insulating post 311 extends axially, and the current-guiding post 312 is tightly sleeved around the insulating post 311, forming a coaxial structure. The sleeve 32 is sleeved around the current-guiding post 312, achieving electrical connection between the sleeve 32 and the current-guiding post 312. The insulating post 311 ensures insulation between the interior of the shaft 31 and the sleeve 32. In this embodiment, current is transmitted through the current-guiding post 312, while the insulating post 311 prevents current from leaking into the interior of the shaft 31. The sleeve 32 sleeves around the current-guiding post 312, forming a conductive path and thus achieving directional current flow.

[0048] For further information, please refer to Figure 3 The sleeve 32 also includes a first guide ring 322 and a second guide ring 323. The resistance ring 321 is sandwiched between the two in the axial direction. One side of the second guide ring 323 is in contact with the first disk 11 in the axial direction. One end of the insulating ring 33 in the axial direction extends to the side of the first disk 11 facing the second disk 21, and the other end of the insulating ring 33 extends to the area where the first guide ring 322 is located.

[0049] Specifically, the first guide ring 322 and the second guide ring 323 are made of a conductive material, such as brass or copper, and the resistance ring 321 can be an alloy resistance material. Preferably, the three are coaxially arranged with the same inner and outer diameters to facilitate stacking and assembly. The insulating ring 33 is preferably made of ceramic, and its axial length covers part of the gap between the guide post 312 and the sleeve 32. One end extends beyond the bottom surface of the first disk 11, and the other end extends to the inside of the first guide ring 322, ensuring partial insulation between the guide post 312 and the sleeve 32, thereby guiding the direction of current. In this embodiment, the sandwich structure of the guide ring and the resistance ring 321 forms a stable resistance path. The provision of the insulating ring 33 precisely controls the current path, avoids short circuits, and facilitates the replacement and maintenance of the resistance ring 321.

[0050] Furthermore, the resistance ring 321, the first guide ring 322, and the second guide ring 323 have the same inner and outer diameters. In actual manufacturing, the three can be stamped or turned into ring structures of the same size, ensuring flatness and concentricity during coaxial assembly. The identical inner and outer diameters allow the axial projections of the components to coincide, eliminating the need for additional positioning structures during assembly, improving production efficiency. It also ensures even current distribution across the ring cross-section, reducing resistance variation. During operation, current flows within the ring region formed by the three components. The identical dimensions ensure a consistent current path, preventing localized resistance increases due to size differences.

[0051] For further information, please refer to Figure 3 In a radial cross-sectional view, the ratio of the cross-sectional area S1 of the resistor ring 321 to the sum of the cross-sectional areas S2 of the first and second guide rings 323 is ≤0.77. This ratio design is intended to ensure that the resistor ring 321 is positioned between and connected in series with the first and second guide rings 323. In the direction of the current path, its length is only a fraction of the entire length of the housing 32, thereby reducing heat generation caused by resistance and improving the accuracy of maximum current measurement. Alternatively, in an axial cross-sectional view, the maximum cross-sectional area of ​​the resistor ring is A1, and the maximum cross-sectional area of ​​the first and second discs 11, 12 is A2, with A1 / A2 being less than or equal to 0.1. In this embodiment, by designing the cross-sectional ratio between the resistor ring 321 and the first and second discs 11, 12, the resistor ring 321 occupies only a small portion of the entire working circuit. This allows for more uniform current flow through the resistor ring 321 due to the current shadowing effect, while also reducing heat generation caused by resistance and improving the accuracy of maximum current measurement. Preferably, the above two embodiments are implemented together to minimize the adverse effects of current unevenness or resistance heating on current measurement.

[0052] There are many ways to measure the relevant parameters of the resistance ring 321. In this embodiment, the first guide ring 322 is embedded with a first connecting wire 324, one end of which is close to one side of the resistance ring 321. The second guide ring 323 is embedded with a second connecting wire 325, which is close to the other side of the resistance ring 321. Both are connected to the external test equipment through the external wire 50. The test equipment can also be set in the working circuit. In specific implementation, the first connecting wire 324 and the second connecting wire 325 can be made of thin copper wires. When manufacturing the first and second guide rings 323, they are fixed therein by embedding or welding. One end of the connecting wire extends to the surface of the resistance ring 321 to reduce the test current conduction path. In this embodiment, the test equipment forms a test loop with the first and second connecting wires 325 and the resistance ring 321, avoiding the influence of other components and directly obtaining the true resistance value of the resistance ring 321. The built-in connecting wire design provides a convenient interface for performance testing of the resistor 100. Testing can be completed without destroying the structure, thereby improving production efficiency and maintenance convenience.

[0053] Based on the above embodiments, the first locking portion 41 is a locking pin that penetrates the first disk 11, and the second locking portion 42 is a locking groove on the second disk 21. The locking pin is inserted and fixed in the locking groove. In specific implementation, the locking pin is a cylindrical pin that penetrates along the axial through-hole of the first disk 11, and the lower end is inserted into the locking groove on the second disk 21. The locking groove is a cylindrical groove that matches the locking pin. Multiple locking grooves are evenly distributed along the circumference of the second disk 21, such as one locking groove every 30 degrees. The depth of the locking groove matches the insertion length of the locking pin to ensure secure locking. This structure achieves fixed relative position between the first disk 11 and the second disk 21 through the cooperation of the locking pin and the locking groove. To adjust the pin position, the locking pin is pulled out, the first disk 11 is rotated to the target position, and the locking pin is inserted to fix it. During operation, the locking pin prevents the two disks from rotating relative to each other, ensuring the stable position of the pin. The multiple locking grooves provide different angle adjustment gears to meet the requirements of different circuit layouts.

[0054] Furthermore, the locking structure 40 also includes a spacer ring 43, which is sleeved on the outer periphery of the lock pin and is located between the first disk body 11 and the second disk body 21, with both ends respectively abutting the two disk bodies. The spacer ring 43 can be made of insulating and wear-resistant materials such as plastic or ceramic, with an inner diameter matching the diameter of the lock pin and an outer diameter larger than the diameter of the lock pin, forming an annular gasket structure. When the lock pin is inserted into the lock slot, the spacer ring 43 is pressed between the two disk bodies to maintain the axial spacing between the two. In this way, direct contact between the first disk body 11 and the second disk body 21 is avoided to cause a short circuit, and the insulation between the two disk bodies is maintained (if the spacer ring 43 is an insulating material). During operation, the spacer ring 43 bears the axial pressure between the two disk bodies, and presses the first disk body 11 against the sleeve body 32 in the axial direction to ensure current transmission between the two.

[0055] Obviously, the embodiments described above are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, those skilled in the art may make other different forms of changes or modifications without making any creative work, and all of these should fall within the scope of protection of the present invention.
