Description

Technical Field

[0001] This application relates to the technical field of electrical equipment, and in particular to a transformer connection assembly for a smart circuit breaker. Background Technology

[0002] Currently, in the design of intelligent circuit breakers, the circuit boards of each layer are usually connected by wires. These wires not only undertake the task of power transmission, but also are responsible for transmitting various control signals.

[0003] However, when the circuit boards in the aforementioned circuit breakers are electrically connected by wires, workers need to manually solder the wires, which increases production costs and reduces production efficiency, and therefore needs to be improved. Utility Model Content

[0004] To simplify the assembly process of circuit breakers and improve production efficiency, this application provides a current transformer connection assembly for intelligent circuit breakers.

[0005] The current transformer connection assembly for a smart circuit breaker provided in this application adopts the following technical solution:

[0006] A current transformer connection assembly for a smart circuit breaker includes a first circuit board, a second circuit board, and a current transformer base located between the first and second circuit boards. The current transformer base has a plurality of clearance holes, in which pin headers are fixedly connected. The two ends of the pin headers protrude from the current transformer base. The first and second circuit boards are respectively provided with female sockets that mate with the pin headers. The female sockets have a plurality of insertion holes for the pin headers to extend into. The insertion holes are provided with conductive elements. The pin headers electrically connect the first and second circuit boards through the conductive elements.

[0007] By adopting the above technical solution, when it is necessary to connect the first circuit board and the second circuit board, simply place the first circuit board in place, then place the current transformer socket on the first circuit board, so that the pin header extends into the socket of the first circuit board, and then place the second circuit board on the current transformer, so that the pin header extends into the socket of the second circuit board. This will achieve the electrical connection between the first circuit board and the second circuit board, without the need for workers to manually solder wires to connect the first circuit board and the second circuit board, thereby simplifying the circuit breaker assembly process and improving production efficiency.

[0008] Optionally, the conductive element includes two opposing springs, with a channel formed between the two springs for the insertion of the pin header, and the minimum spacing of the channel is less than the width of the pin header.

[0009] By adopting the above technical solution, when the pin header is inserted into the socket, it will be stably held in the socket by two spring clips, making it difficult for the pin header to move out of the socket. The connection between the pin header and the first circuit board and the second circuit board is highly stable, thereby making the electrical connection between the first circuit board and the second circuit board strong.

[0010] Optionally, the spacing between the clearance holes, pin headers, and insertion holes is the same and they correspond one-to-one.

[0011] By adopting the above technical solution, when connecting the first circuit board and the second circuit board, only one pin header and socket need to be aligned to match the remaining pin headers and sockets, eliminating the need for personnel to manually align each pin header and socket. Compared to when the number of sockets exceeds the number of pin headers, this connection method reduces the step of aligning each pin header and socket individually, decreasing the possibility of pin headers bending against the socket due to misalignment, and facilitating the connection between pin headers and sockets.

[0012] Optionally, the current transformer base is provided with a male plug, and the male plug has several through holes for the pin header to pass through. The two ends of the pin header pass through the current transformer base and are then fixed in the through holes. Then the pin header extends into the plug hole. When the pin header extends into the plug hole, the male plug abuts against the current transformer base and the female base.

[0013] By adopting the above technical solution, when the first circuit board and the second circuit board are connected together, there is usually a space between the female connector and the current transformer socket, and the male connector abuts between the female connector and the current transformer socket, which can protect the pin header from being bent by external force and increase the stability of the connection between the female connector and the pin header.

[0014] Optionally, the transformer base is provided with a limiting groove for the insertion of a male connector.

[0015] By adopting the above technical solution, when the pin header is connected to the female connector, the limiting groove can limit the male connector, resulting in high stability of the male connector and good protection of the pin header.

[0016] Optionally, the pin headers have chamfered ends away from the male connector.

[0017] By adopting the above technical solution, when connecting the male connector and the female connector, the chamfer at both ends of the pin header makes the width of both ends of the pin header slightly smaller than the diameter of the socket, which makes it easier for the pin header to extend into the socket, thereby facilitating the connection between the male connector and the female connector and making the operation convenient.

[0018] Optionally, the current transformer base includes a connecting part for setting pin headers and a mounting part for mounting current transformer coils. The connecting part and the mounting part are detachably connected, and the clearance hole is formed on the connecting part.

[0019] By adopting the above technical solution, when the pin header wears out and its conductivity deteriorates, the pin header can be removed from the socket first, then the connecting part can be removed from the mounting part, and then the connecting part with the new pin header can be connected to the mounting part to replace the new pin header. Finally, the new pin header can be inserted into the socket to connect the first circuit board and the second circuit board without replacing the entire current transformer socket. This method is simple to operate, saves resources, and extends the service life of the connection components.

[0020] Optionally, a connecting block is provided on the side of the connecting part near the mounting part, and a mounting groove is provided on the mounting part, with the connecting block and the mounting groove being inserted into each other.

[0021] By adopting the above technical solution, when it is necessary to separate the connecting part and the mounting part, simply remove the connecting block from the mounting slot; when it is necessary to connect the connecting part and the mounting part, simply insert the connecting block into the mounting slot. This facilitates the disassembly and installation of the connecting part, and thus facilitates the replacement of the pin header.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When it is necessary to connect the first circuit board and the second circuit board, simply insert the pin header into the socket, which makes it easy to connect the first circuit board and the second circuit board and simplifies the assembly process of the circuit breaker.

[0024] 2. A conductive element is provided inside the socket. The conductive element consists of two spring pieces. When the pin header is inserted into the socket, the two spring pieces can clamp and fix the pin header inside the socket, so that the connection between the pin header and the female socket is highly stable.

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses a current transformer connection assembly for a smart circuit breaker.

[0033] Example 1

[0034] Reference Figure 1 and Figure 2 A current transformer connection assembly for a smart circuit breaker includes a first circuit board 1, a second circuit board 2, and a current transformer base 3 located between the first circuit board 1 and the second circuit board 2. The current transformer base 3 has a plurality of clearance holes 31. A housing 11 is provided on one side of the second circuit board 2. The housing 11 partially covers the outside of the second circuit board 2 to protect the second circuit board 2.

[0035] Reference Figure 2 The transformer base 3 has a limiting groove 32, in which a male plug 6 is provided. The groove wall of the limiting groove 32 abuts against the side wall of the male plug 6, thereby limiting the position of the male plug 6 and stabilizing its position. The male plug 6 has several through holes 61. The spacing between the clearance holes 31 and the through holes 61 is the same and their positions correspond one-to-one. The clearance holes 31 and the through holes 61 are fixedly connected to a pin header 5, with both ends of the pin header 5 passing through the transformer base 3 and the male plug 6.

[0036] Reference Figure 2 and Figure 3 The first circuit board 1 and the second circuit board 2 are each fixed with a female connector 4 on the side closest to each other. The female connector 4 has several holes 41 for the pin header 5 to be inserted. After the pin header 5 is connected to the relief hole 31 and the through hole 61, both ends of the pin header 5 extend into the hole 41. At this time, the male connector 6 abuts between the current transformer base 3 and the female connector 4, which plays the role of protecting the pin header 5. The pin header 5 can electrically connect the first circuit board 1 and the second circuit board 2.

[0037] Reference Figure 2 and Figure 3 A conductive element 42 is provided in the socket 41. The conductive element 42 consists of two opposing spring pieces 421. A channel 422 for the insertion of the pin header 5 is formed between the two spring pieces 421, and the minimum distance between the channels 422 is less than the width of the pin header 5. The two spring pieces 421 can undergo elastic deformation. When the pin header 5 is inserted into the socket 41, the two spring pieces 421 will clamp and fix the pin header 5 inside the socket 41, thereby electrically connecting the first circuit board 1 and the second circuit board 2.

[0038] The implementation principle of a current transformer connection assembly for a smart circuit breaker according to an embodiment of this application is as follows: When connecting a first circuit board 1 and a second circuit board 2, simply place the first circuit board 1 in position, then place the current transformer base 3 on the first circuit board 1, so that the pin header 5 extends into the female socket 4 of the first circuit board 1 and is located in the channel 422. Then place the second circuit board 2 on the current transformer base 3, so that the pin header 5 extends into the female socket 4 of the second circuit board 2 and is located in the channel 422. This completes the entire assembly process. It eliminates the complex wiring procedures of the circuit breaker, simplifies the assembly process, and improves the production efficiency of the circuit breaker.

[0039] Example 2

[0040] Reference Figure 4 The difference between this embodiment and Embodiment 1 is that the current transformer base 3 includes a connecting part 33 for setting the pin header 5 and a mounting part 34 for mounting the current transformer coil, with a clearance hole 31 formed on the connecting part 33. In this embodiment, there are preferably three mounting parts 34 and two connecting parts 33, with each connecting part 33 positioned between every two adjacent mounting parts 34. Connecting blocks 331 are provided on both sides of the connecting part 33 near the mounting part 34, and mounting grooves 341 matching the shape and size of the connecting blocks 331 are provided on the mounting part 34. The connecting part 33 and the mounting part 34 are detachably connected by the insertion and engagement of the connecting blocks 331 and the mounting grooves 341. In this embodiment, the direction in which the connecting blocks 331 extend into the mounting grooves 341 is perpendicular to the direction in which the pin header 5 extends into the insertion holes 41; however, in other cases, the specific direction can be selected according to customer requirements.

[0041] The implementation principle of a current transformer connection assembly for a smart circuit breaker according to an embodiment of this application is as follows: When the pin header 5 wears down, resulting in poor conductivity, the connection block 331 can be moved out of the mounting slot 341, separating the connection part 33 from the mounting part 34. Then, the connection part 33 with the new pin header 5 can be replaced, and the connection structure can continue to be used. Compared to replacing the entire current transformer base 3, this saves resources and is convenient for disassembly and assembly.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
