[0006] Furthermore, the load device also includes an adapter, which is mounted on the support frame, and the adapter is mounted on both ends of each resistor; One end of the adapter is connected to the resistor, and the other end extends out of the support frame and is detachably connected to the longitudinal link and / or the transverse link.

[0007] Furthermore, a first insulating element is installed between the adapter and the support frame.

[0008] Furthermore, the adapter includes a first segment, a second segment, and a third segment, wherein the first segment and the third segment are respectively connected to both ends of the second segment at an angle and are located on the same side of the second segment; The two ends of the first insulating member are respectively connected to the second segment and the support frame; The end of the first segment opposite to the second segment is connected to the resistor, and the end of the third segment opposite to the second segment is detachably connected to the longitudinal link and / or the transverse link.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] In a typical power supply testing environment, the load used for testing is usually a fixed resistor with one load per machine. However, this type of load is either not adjustable or has a complex adjustment process, making it unsuitable for debugging the power supply of various specifications.

[0025] In view of this, see Figure 1The load device provided in this embodiment of the utility model includes a support frame 100, a resistor assembly 200, and a connecting assembly 300. The resistor assembly 200 includes a plurality of resistor elements 210, which are arranged in N rows and M columns, and each resistor element 210 is mounted on the support frame 100. The connecting assembly 300 includes a longitudinal connecting element 310 and a transverse connecting element 320. The ends of two adjacent resistor elements 210 in the same row that are located on the same side of the support frame 100 are detachably connected to the transverse connecting element 320. The ends of two adjacent resistor elements 210 in the same column that are located on the same side of the support frame 100 are detachably connected to the longitudinal connecting element 310.

[0026] Specifically, resistors 210 are mounted on the support frame 100, and multiple resistors 210 are independent of each other. Resistors 210 are used externally to connect cables or to the connection assembly 300 for series or parallel connection. In this embodiment, resistors 210 are connected to the connection assembly 300 by screws. When adjusting the load of the load device, it is only necessary to adjust the arrangement of the longitudinal connecting members 310 and the transverse connecting members 320 in the connection assembly 300, connecting the longitudinal connecting members 310 and the transverse connecting members 320 to the resistors 210 that need to be connected by screws. Through multiple sets of series and parallel connections of resistors 210, the load resistance value can be quickly changed to meet the required load demand. It is worth noting that one end of each resistor 210 may not be connected to the horizontal connector 320 or the vertical connector 310; it may be connected to only one horizontal connector 320 or only one vertical connector 310; it may be connected to one horizontal connector 320 and one vertical connector 310 simultaneously, in which case the horizontal connectors 320 and vertical connectors 310 are stacked; it may be connected to one horizontal connector 320 and two vertical connectors 310 simultaneously, in which case the horizontal connectors 320 and two vertical connectors 310 are stacked; it may be connected to one vertical connector 310 and two horizontal connectors 320 simultaneously, in which case the vertical connectors 310 and two horizontal connectors 320 are stacked; it may be connected to two vertical connectors 310 and two horizontal connectors 320 simultaneously, in which case the two horizontal connectors 320 and two vertical connectors 310 are stacked. When the horizontal connectors 320 and vertical connectors 310 are stacked, their order can be set as needed. This load device can be used to meet resistive load requirements of any voltage and current level. For example, please refer to... Figure 1 , Figure 3 and Figure 4 The resistor 210 is set to 100V 100A and is a fixed resistor with a resistance of 1Ω. The support frame 100 can install 6 rows and 4 columns of resistors 210. This load device can meet the load requirements from a maximum of 100V 2400A (all resistors 210 in parallel) to 2400V 100A (all resistors 210 in series).

[0027] The resistor 210 is set as a fixed resistor; each resistor 210 is mounted on the support frame 100, which provides support for the resistor assembly 200; the resistor 210 is detachably connected to the horizontal link 320 or the vertical link 310 to realize the series or parallel connection between two adjacent resistors 210.

[0028] For example: If two adjacent resistors 210 in the same row are connected at only one end by a horizontal link 320, then the two resistors 210 are connected in series. If both ends of two adjacent resistors 210 in the same row are connected by horizontal links 320, then the two resistors 210 are connected in parallel. Similarly, if two adjacent resistors 210 in the same column are connected at only one end by a vertical link 310, then the two resistors 210 are connected in series. If both ends of two adjacent resistors 210 in the same column are connected by vertical links 310, then the two resistors 210 are connected in parallel. Because both the horizontal connector 320 and the vertical connector 310 are connected to the resistor 210 in a detachable manner, the resistors 210 at different positions can be quickly connected in series or in parallel by installing the horizontal connector 320 and the vertical connector 310, thereby enabling the resistance value of the load device to change rapidly to meet the load requirements.

[0029] This load device can quickly and accurately provide a matching load for different test conditions by rapidly connecting fixed-value resistors 210 in series or parallel, thereby expanding its applicability.

[0030] The structure of link component 300 is described in detail below: In the optional solutions provided by this utility model embodiment, the longitudinal connecting member 310 and the transverse connecting member 320 have the same shape and size.

[0031] Specifically, see Figure 3 Both the longitudinal connector 310 and the transverse connector 320 are square plate structures with consistent length and width, allowing for interchangeability and eliminating the need to distinguish between connectors during installation, thus improving installation efficiency. Furthermore, both ends of the longitudinal connector 310 and the transverse connector 320 are provided with first connecting holes, through which screws pass to connect to the corresponding resistor 210. Preferably, both the longitudinal connector 310 and the transverse connector 320 are made of copper or aluminum plates.

[0032] The longitudinal link 310 and the transverse link 320 are designed as universal components, which facilitates the connection between the link assembly 300 and the resistor 210, simplifies the structure of the load device, and further facilitates the adjustment of the resistance value.

[0033] In the optional solution provided by this utility model embodiment, the load device further includes an adapter 400, which is installed on the support frame 100, and the adapter 400 is installed at both ends of each resistor 210; one end of the adapter 400 is connected to the resistor 210, and the other end extends out of the support frame 100 and is detachably connected to the longitudinal link 310 and / or the transverse link 320.

[0034] Specifically, see Figure 1 and Figure 4 The adapter 400 is conductive, and each resistor 210 has an adapter 400 installed at both ends, so that each resistor 210 has a connection point extending out of the support frame 100 at both ends. The end of the adapter 400 extending out of the support frame 100 is provided with a second connection hole 431. When installing the connecting assembly 300, the first connection hole of the corresponding longitudinal connecting member or transverse connecting member 320 is aligned with the second connection hole 431, and the screw passes through the first connection hole and the second connection hole 431 to realize the connection between the adapter 400 and the connecting assembly 300, thereby realizing the connection between the resistor 210 and the connecting assembly 300.

[0035] The adapter 400 is configured such that the connection point of the resistor 210 extends out of the support frame 100, facilitating connection with the link assembly 300.

[0036] In the optional solutions provided by the embodiments of this utility model, see Figure 2 A first insulating element 510 is installed between the adapter 400 and the support frame 100.

[0037] Specifically, the first insulating element 510 is configured as a ceramic pillar.

[0038] The first insulating component 510 provides insulation to prevent short circuits in the load device.

[0039] In the optional embodiment of this utility model, the adapter 400 includes a first segment 410, a second segment 420, and a third segment 430. The first segment 410 and the third segment 430 are respectively connected to the two ends of the second segment 420 at an angle and are located on the same side of the second segment 420. The two ends of the first insulating member 510 are respectively connected to the second segment 420 and the support frame 100. The end of the first segment 410 facing away from the second segment 420 is connected to the resistor 210, and the end of the third segment 430 facing away from the second segment 420 is detachably connected to the longitudinal connecting member 310 and / or the transverse connecting member 320.

[0040] Specifically, see Figure 6A connector 400 with a first section 410, a second section 420, and a third section 430 is formed by bending a conductive plate, thereby enhancing the connection strength between the components. The third section 430 is provided with the aforementioned second connection hole 431. Further, see... Figure 2 The first insulating member 510 is vertically arranged, and its two ends are respectively connected to the second section 420 and the support frame 100; the second section 420 is provided with a third connecting hole 421, which is connected to the first insulating member 510.

[0041] The adapter 400 is in the shape of three bends, so that one end can be connected to the resistor 210 and the other end can extend out of the support frame 100. At the same time, the vertical setting increases the contact area between the adapter 400 and the connecting component 300, enhancing the convenience and strength of the connection.

[0042] In the optional solution provided by this utility model embodiment, a second insulating element 520 is installed between the first segment 410 and the support frame 100.

[0043] Specifically, see Figure 2 One side of the first segment 410 is attached to the resistance wire 211 of the resistor 210, and the other side is connected to the second insulating member 520. Furthermore, the first segment 410 is provided with a fourth connecting hole 411. The second insulating member 520 is horizontally positioned, with one end connected to the fourth connecting hole 411 and the other end connected to the support frame 100. It is worth noting that the resistance wire 211 attached to the first segment 410 bypasses the fourth connecting hole 411. The second insulating member 520 is configured as a ceramic pillar.

[0044] The first segment 410 is connected to the support frame 100 through the second insulating component 520, which achieves insulation while improving the installation stability of the adapter 400.

[0045] The structure and shape of the support frame 100 are described in detail below: In the optional solution provided by this utility model embodiment, the support frame 100 includes N rows of support components, each row of support components includes two oppositely arranged support plates 110; both ends of each resistor 210 are respectively installed on the two support plates 110; the adapter 400 is installed on the support plate 110, with one end connected to the resistor 210 and the other end extending out of the support plate 110.

[0046] Specifically, each support assembly contains M columns of resistors 210, resulting in multiple resistors 210 arranged in N rows and M columns. See also Figure 3 The support frame 100 also includes four columns 120, and the two ends of the support plate 110 are perpendicularly connected to two columns 120 respectively; the columns 120 provide support and fixation for the support plate 110.

[0047] The support plate 110 provides support and fixation for the resistor 210 and the adapter 400.

[0048] In the optional solution provided by this utility model embodiment, the support plate 110 includes a first plate 111 and a second plate 113, with the first plate 111 and the second plate 113 connected at an angle; the resistor 210 is installed on the first plate 111, and the adapter 400 is installed on the second plate 113.

[0049] Specifically, see Figure 7 The first plate 111 and the second plate 113 are square plate structures and are connected vertically. See also Figure 2 and Figure 5 The resistor 210 is mounted on the first plate 111. A first insulating component 510 is installed between the second section 420 of the adapter 400 and the second plate 113. A second insulating component 520 is installed between the first section 410 of the adapter 400 and the first plate 111.

[0050] The support plate 110 is bent, which enables the adapter 400 to be fixed at two points with the support plate 110, thereby improving the support strength of the adapter 400.

[0051] In the optional solution provided by this utility model embodiment, the end face of the first plate 111 away from the second plate 113 is provided with a groove 112, and the resistor 210 is inserted into the groove 112.

[0052] Specifically, see Figure 7 The top surface of the first plate 111 is recessed downward to form a groove 112. The resistor 210 is attached to the groove 112 and is locked in place by screws.

[0053] The first plate 111 has a groove 112 to facilitate the positioning and installation of the resistor 210.

[0054] The structure and shape of resistor 210 are described in detail below; In the optional solution provided by this utility model embodiment, the resistor 210 includes a resistance wire 211, an insulating cylinder 212 and a support rod 213. The insulating cylinder 212 is fitted with the support rod 213, and the resistance wire 211 is wound around the outer wall of the insulating cylinder 212. The support rod 213 is installed on the support frame 100.

[0055] Specifically, the insulating cylinder 212 has an annular cross-section and is fitted onto the support rod 213; the resistance wire 211 is wound around the outer wall of the insulating cylinder 212, and the insulating cylinder 212 serves as an insulating element. See also... Figure 5 Both ends of the support rod 213 protrude from the insulating cylinder 212. Both ends of the support rod 213 are inserted into the grooves 112 of the support plates 110 on both sides, and both ends of the support rod 213 are provided with external threads for threaded connection with nuts to achieve locking.

[0056] The support rod 213 enables the resistor 210 to be installed on the support frame 100, and the insulating cylinder 212 provides insulation.
