Abstract
Description
Technical Field
[0001] The utility model relates to a composite gold resistor with improved structure, which is mainly used for providing an assembly structure with a printed circuit board, so as to provide an innovative structure for accurate current measurement by designing a sampling point at a middle section. Background Art
[0002] According to the current application of printed circuit boards, they have become one of the indispensable components in electronic products. In order to better apply printed circuit boards, they must be matched with appropriate resistance components to enable the current to flow stably and smoothly.
[0003] However, the current printed circuit board and alloy resistor components are usually assembled in the form of pads, and the alloy resistor mainly plays the role of detecting the current and is used to feedback the changing current in the circuit, often called sampling resistor or sampling resistor. Although the alloy resistor has the characteristics of low resistance, high stability, high power, etc., due to the strong metal conductivity of the alloy resistor, it is easy to cause the current to change when sampling the resistor, so that the detection is wrong, and multiple sampling is required to determine. Therefore, it is necessary to consider the occurrence of multiple sampling in the operation, which increases the waste of procedures and time in the operation. Therefore, it is necessary to propose specific improvement plans to meet the needs of industrial progress and further provide users with more choices. Utility Model Content

[0006] In order to achieve the purpose of accurate current measurement, the utility model provides a composite gold resistor with an improved structure. The composite gold resistor is rectangular and has a length of A value. Two corresponding sampling points are provided at the middle sections of the two sides of the composite gold resistor. Accommodation spaces are opened on both sides of the sampling points, and the length of the sampling points is B value. The ratio of the aforementioned A value: B value is 8 to 10:1.
[0007] Optionally, the ratio of the length to the width of the composite gold resistor is 1.5:1.

[0021] The following will illustrate the spirit and methods of the present invention with the accompanying drawings and detailed explanations. Any person having ordinary knowledge in the technical field can change and modify the present invention according to the technology taught by the present invention after understanding the best embodiment of the present invention, without departing from the spirit and scope of the present invention.
[0022] See also Figure 1-Figure 3 The structure-improved composite gold resistor provided by the utility model comprises:
[0023] A composite gold resistor 1 is rectangular in shape, with a length A value of 8 to 10, and a bridge-shaped notch 11 is dug at the bottom of the rectangle;
[0024] The second sampling point 2 is set correspondingly at the middle section of the two sides of the composite gold resistor 1, and its length is the B value, which can be 1;
[0025] The four containing spaces 3 are arranged at two sides of the sampling point 2.
[0026] In summary, the ratio of the length to the width of the composite gold resistor 1 is 1.5:1.
[0027] See also Figure 4 and Figure 5During implementation, the composite gold resistor 1 is attached to the printed circuit board 5 with its bottom, and a pad 4 is provided between the two to fix the composite gold resistor 1 and the printed circuit board 5. At this time, the top surface of the composite gold resistor 1 faces upward, and its sampling point 2 is provided at the middle section of the two sides of the composite gold resistor 1, and is provided on two corresponding sides, and both sides of the sampling point 2 are provided with a receiving space 3 to accommodate a measuring tool (not shown), which is conducive to testing the current of the sampling point 2. When the ratio of the full length A value of the composite gold resistor 1 to the full length B value of the sampling point 2 is 8 to 10:1, the most accurate current data can be obtained. For example: the full length of the A value is 17.2, the width is 11, and the full length of the B value is 2, which is the best physical value and can be used for accurate current measurement.
[0028] In summary, the sampling point at the middle section of the structurally improved composite gold resistor structure of the utility model is designed with a perfect ratio between its overall length and the sampling point, so that it can accurately measure stable current values, thereby reducing the number of measurements and further improving work efficiency. As a result, the utility model is far superior to various products currently on the market and is a patented design with innovation and practicality.
