DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments.

[0030] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] In one aspect of an embodiment of the present application, a distributed current and voltage sampling system is provided, including a control module 12 and at least one terminal module 11 located on a base 10, wherein a sampling unit 11A is provided on each terminal module 11, and the control module 12 is crimped and connected to the sampling unit 11A of at least one terminal module 11 to transmit the sampling signal of the terminal module 11 to the control module 12.

[0033] The control module 12 is inserted into the base 10 , and the terminal modules 11 are provided with a sampling unit 11A. The control module 12 and the sampling unit 11A are connected to obtain a sampling signal of the terminal module 11 through the sampling unit 11A.

[0034] When there are multiple terminal modules 11, Figure 1 As shown, a plurality of terminal modules 11 are arranged in two rows on both sides of the base 10. The control module 12 is located between the two rows of terminal modules 11, and the control module 12 is connected to the sampling unit 11A of at least one terminal module 11 on both sides of the base 10.

[0035] When the control module 12 and the sampling unit 11A are connected, Figure 4 As shown, the distributed current and voltage sampling system also includes a pole connecting plate 12a, which is crimped onto a sampling unit 11A of at least one terminal module 11 to achieve crimping conduction and transmit the sampling signal in the terminal module 11 to the control module 12, thereby realizing the sampling function.

[0036] Therefore, in the distributed current and voltage sampling system provided by the embodiment of the present application, a control module 12 and at least one terminal module 11 are arranged on the base 10, a sampling unit 11A is arranged on the terminal module 11, the control module 12 and the sampling unit 11A of at least one terminal module 11 are crimped and connected, and the sampling signal in the terminal module 11 is transmitted to the control module 12, thereby realizing the sampling function of the terminal module 11; the present application adopts the method of crimping and connection to realize sampling, so that the sampling signal between the terminal module 11 and the control module 12 can be transmitted stably, and the structure is simple, the space occupied is small, the use is convenient, and the system can be used immediately after being connected, thereby improving the comprehensive performance of the system.

[0037] like Figure 5 , Figure 6 As shown, the sampling unit 11A is connected to the sampling adapter board 110, and a pad or a contact point is set on the electrode connection board 12a, and the electrode connection board 12a is connected to the sampling adapter board 110 through the pad or the contact point.

[0038] For example, the pole connecting plate 12a is located between the terminal modules 11 on both sides, and a welding pad or contact point is set on the pole connecting plate 12a corresponding to the position of the sampling adapter plate 110. The welding pad or contact point is pressed on the sampling adapter plate 110 and squeezes the sampling adapter plate 110 to achieve crimping and conduction between the pole connecting plate 12a and the terminal module 11.

[0039] There may be multiple terminal modules 11; Figure 2 As shown, the plurality of terminal modules 11 form at least one group, and the terminal modules 11 in the same group include a first terminal module 11 a and a second terminal module 11 b which are correspondingly arranged and respectively located on two sides of the base 10 .

[0040] like Figure 2 , multiple first terminal modules 11a are located in the same row, and multiple second terminal modules 11b are located in the same row; for example, a first terminal module 11a1 and a first terminal module 11a2 are arranged on one side of the base 10, and multiple other first terminal modules are arranged between the first terminal module 11a1 and the first terminal module 11a2; a second terminal module 11b1 and a second terminal module 11b2 are arranged on the other side of the base 10, and multiple other second terminal modules are also arranged between the second terminal module 11b1 and the second terminal module 11b2.

[0041] The first terminal module 11 a and the second terminal module 11 b of the same group are symmetrically arranged on the base 10 along the center point of the base 10 , which can solve the problem of switching and adjusting the direction of the terminal module 11 .

[0042] Different terminal modules 11 can realize different sampling functions, such as sampling current, sampling voltage, etc. The matching positions of the first terminal module 11a and the second terminal module 11b are set according to actual needs.

[0043] For example Figure 2 In the embodiment, when the first terminal module 11a1 and the second terminal module 11b1 are a group, the first terminal module 11a1 and the second terminal module 11b1 are arranged opposite to each other on the base 10; at this time, the positions of the first terminal module 11a1 and the second terminal module 11b1 are interchangeable, and the exchange of the positions does not affect the sampling of the product and the realization of the function and structure. When the first terminal module 11a1 and the second terminal module 11b1 are exchanged with each other, the positions before and after the exchange are as follows Figure 3 shown.

[0044] Similarly, the positions of the first terminal module 11a2 and the second terminal module 11b2, the first terminal module 11a3 and the second terminal module 11b3, and other groups of the first terminal module 11a and the second terminal module 11b may also be interchanged.

[0045] Alternatively, the first terminal module 11a1 and the second terminal module 11b2 may be set as a group, and the first terminal module 11a1 and the second terminal module 11b2 may be interchangeable, and similarly, the first terminal module 11a2 and the second terminal module 11b1 in the same group may be interchangeable.

[0046] The symmetrical arrangement of the first terminal module 11a and the second terminal module 11b in the same group along the center point on the base 10 is a prerequisite for interchangeability of the first terminal module 11a and the second terminal module 11b. Whether to interchange and how to interchange can be selected according to specific needs.

[0047] In addition, when the first terminal module 11a and the second terminal module 11b are interchangeable, their respective terminal interfaces need to match. For example, the first terminal module 11a1 and the second terminal module 11b1 both have four terminal interfaces and can be interchanged; the first terminal module 11a3 and the second terminal module 11b3 both have one terminal interface and can be interchanged; but the first terminal module 11a1 and the second terminal module 11b3 cannot be interchanged because their respective terminal interfaces do not match.

[0048] As mentioned above, there may be only one terminal module 11, for example Figure 2 Only the first terminal module 11a1 may be disposed on the middle base 10 , and there is no need to dispose the second terminal module 11b1 , the first terminal module 11a2 , the second terminal module 11b2 , the first terminal module 11a3 , the second terminal module 11b3 or other terminal modules 11 .

[0049] When the first terminal module 11a and the second terminal module 11b of the same group are symmetrically arranged along the center point, the problem of switching and adjusting the terminal module 11 can be solved. Correspondingly, the sampling unit 11A has a pressing interface for crimping with the control module 12, and the pressing interface is symmetrically arranged along the central axis L of the base 10, and the central axis L of the base 10 is perpendicular to the connection direction of the two rows of terminal modules 11 on the base 10.

[0050] Specifically, the pressing interface is located on the sampling adapter plate 110, and the pressing interface is symmetrically arranged with respect to the central axis L of the base 10 (along Figure 2 The sampling adapter plate 110 is fixed on the terminal module 11, and the pressing interface of the sampling adapter plate 110 is crimped with the corresponding terminal module 11. When the terminal modules 11 of the same group are rotated 180° and exchanged to the opposite side, since the pressing interfaces on both sides of the sampling adapter plate 110 are symmetrically arranged, the positions of the pressing interfaces on the terminal modules 11 of the same group before and after the exchange are consistent, so that the pressing interfaces of the terminal modules 11 rotated to the opposite side can continue to be used, and different terminal modules 11 can be flexibly replaced to save parts.

[0051] For example Figure 3 As shown, the first terminal module 11a1 and the second terminal module 11b1 are interchanged. Since the pressing interface corresponding to the first terminal module 11a1 and the pressing interface corresponding to the second terminal module 11b1 are symmetrical along the central axis of the base 10, the interchange does not affect the use and avoids the need to replace other parts.

[0052] In addition, the control module 12 is connected to the first terminal module 11a and / or the second terminal module 11b of the same group. That is, when the control module 12 collects signals from the terminal module 11, it can collect signals from the first terminal module 11a, the second terminal module 11b, or both.

[0053] Correspondingly, there is at least one pole connecting plate 12 a , and the pole connecting plate 12 a and the terminal modules 11 are arranged in a one-to-one correspondence.

[0054] When there is only one terminal module 11, a polarization plate 12a is set to correspond to this terminal module 11; when there are two terminal modules 11 in a group, a polarization plate 12a is set to correspond to the group of terminal modules 11, for example, a polarization plate 12a is set between the first terminal module 11a1 and the second terminal module 11b1.

[0055] On this basis, there is at least one control module 12, and the control module 12 corresponds to the pole connecting plate 12a one by one.

[0056] For example, a control module 121 is provided between the first terminal module 11a1 and the second terminal module 11b1, a control module 122 is provided between the first terminal module 11a2 and the second terminal module 11b2, and control modules are also provided for other groups of terminal modules 11. Each control module 12 is provided with a polarization plate 12a.

[0057] The above-mentioned associated structures correspond one to one and are distributed on the base 10 to form a distributed sampling layout, which can solve application scenarios such as arbitrary sampling and total leakage of branch circuits.

[0058] On the other hand, Figure 1 and Figure 7 As shown, the embodiment of the present application further discloses a base device 100, including a base 10 and any one of the above distributed current and voltage sampling systems arranged on the base 10. A circuit breaker 101 is plugged in and out of the base 10, and the circuit breaker 101 is electrically connected to the terminal modules 11 on both sides, which is used to realize sampling of parameters such as current and voltage in the circuit breaker 101, and can also realize parameter sampling of the incoming and outgoing lines of the circuit breaker 101 and the surrounding circuits.

[0059] For example, a guide rail 10a is set at the bottom of the base 10 for sliding connection between the base 10 and an external device; two rows of terminal modules 11 are set on the base 10, and a control module 12 and a pole connecting plate 12a are set between the two rows of terminal modules 11. The pole connecting plate 12a is crimped onto the sampling adapter plates 110 of the two rows of terminal modules 11 to achieve conduction, so as to transmit the sampling signals in the terminal modules 11 to the control module 12.

[0060] The base device 100 includes the same structure and beneficial effects as the distributed current and voltage sampling system in the aforementioned embodiment. The structure and beneficial effects of the distributed current and voltage sampling system have been described in detail in the aforementioned embodiment and will not be repeated here.

[0061] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
