[0002] Metal indicator lights are widely used in various electrical devices, resulting in a significant demand for them in existing equipment. In current technology, one method of wiring metal indicator lights involves using a screwdriver to tighten screws and crimp the wires. This method is labor-intensive, reduces work efficiency, and is prone to loosening during equipment operation, posing a safety hazard and requiring frequent maintenance. Another method uses a pin structure as the wiring terminal. This method involves soldering the wires to the pin structure. This method is inefficient, the soldering time is too long and can damage the product, and once damaged, it is inconvenient to disassemble, replace, or repair the product. Utility Model Content

[0003] To address the aforementioned technical problems, embodiments of this application provide an indicator light terminal block and an indicator light system to solve at least one of the aforementioned problems.

[0004] According to a first aspect of the present application, an indicator light terminal block is provided, which includes a terminal block housing and at least two metal clamping springs. The metal clamping springs are disposed inside the terminal block housing and are used to engage with the pins of the indicator light. The terminal block housing is provided with at least one set of fastening hooks, which includes at least two fastening hooks. When the indicator light is in a state of being engaged with the indicator light terminal block, the fastening hooks are used to engage with a limiting structure on the indicator light to prevent the indicator light from separating from the indicator light terminal block.

[0005] Optionally, the fastening hook is connected to the terminal block housing via a support cantilever. The first end of the fastening hook is provided with a hook portion protruding into the terminal block housing. The hook portion is used to cooperate with the limiting structure on the indicator light to prevent the indicator light from separating from the indicator light terminal block.

[0006] Optionally, the connection point between the fastening hook and the support cantilever is located between the first end and the second end of the fastening hook. When the second end of the fastening hook is pressed and moves towards the terminal block housing, the first end of the fastening hook moves away from the terminal block housing.

[0007] Optionally, the terminal block housing is provided with a first foolproof structure, which is used to cooperate with a second foolproof structure provided on the indicator light.

[0008] Optionally, the first foolproof structure includes a foolproof groove disposed on the terminal block housing, and the second foolproof structure of the indicator light includes a foolproof protrusion, the foolproof groove being used to engage with the foolproof protrusion.

[0009] Optionally, a limiting spring is provided on the metal clip spring, and the metal clip spring is fixedly installed in the terminal block housing by the limiting spring. The metal clip spring includes a pin mounting cavity for inserting the pin of the indicator light and making conductive connection with the pin of the indicator light.

[0010] Optionally, the metal clip spring also includes a wire clamping spring, which forms a wire mounting cavity. The wire is inserted into the wire mounting cavity and clamped by the wire clamping spring.

[0011] Optionally, the metal clip spring includes a bottom section, a first bent section, and a second bent section. The first bent section is disposed on a first side of the bottom section, and the second bent section is disposed on a second side of the bottom section opposite to the first side, to form a pin mounting cavity.

[0012] Optionally, a pin limiting member that can be elastically deformed is provided in the pin mounting cavity. The pin limiting member includes an insertion guide section.

[0013] Optionally, one end of the limiting spring is disposed on the bottom section, and the limiting spring extends in a direction away from the bottom section.

[0014] According to another aspect of this application, an indicator light system is provided, which includes an indicator light and the aforementioned indicator light terminal block. The indicator light includes a limiting structure and a pin. The limiting structure includes an outwardly extending limiting protrusion. When the indicator light is plugged into the indicator light terminal block, the pin is inserted into a metal spring and electrically connected to the metal spring. The limiting structure cooperates with a fastening hook to prevent the indicator light from separating from the indicator light terminal block.

[0015] The indicator light terminal block of this application embodiment uses a fastening hook on the terminal block housing.

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0027] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0028] like Figures 1 to 8As shown, according to an embodiment of this application, an indicator light terminal block is provided. The indicator light terminal block includes a terminal block housing 10 and at least two metal clamping springs 11. The metal clamping springs 11 are disposed inside the terminal block housing 10 and are used to engage with the pins 21 of the indicator light 20. The terminal block housing 10 is provided with at least one set of fastening hooks, which includes at least two fastening hooks 12. When the indicator light 20 is in the state of being engaged with the indicator light terminal block, the fastening hooks 12 are used to engage with the limiting structure 22 on the indicator light 20 to prevent the indicator light 20 from separating from the indicator light terminal block.

[0029] The indicator light terminal block provided in this embodiment uses a fastening hook 12 in the terminal block housing 10. The fastening hook 12 engages with the limiting structure 22 on the indicator light 20 to limit the indicator light 20, preventing it from separating from the terminal block. Simultaneously, the metal spring clip 11 in the terminal block engages with the pin 21 of the indicator light 20 to achieve a conductive connection, ensuring a stable and reliable connection between the indicator light 20 and the terminal block. This plug-in connection method makes indicator light wiring more convenient and quick, eliminating the need for soldering and increasing connection efficiency. Furthermore, the fastening hook 12 and limiting structure 22 method of preventing separation is more reliable than bolt-tightening wiring, especially in environments with strong vibrations. Bolts and other threaded connections are prone to loosening in such environments, while this hook-and-loop connection effectively prevents loosening.

[0030] like Figures 1 to 5 As shown, the indicator light provided in this embodiment includes an indicator light housing, pins 21 disposed within the indicator light housing, and a light source. The pins 21 are made of conductive material and are connected to the light source to provide power to it. The light source can be a single-color or multi-color metallic indicator light source. The number of pins 21 in the indicator light can be determined based on the number of colors of the light source in the indicator light. For example, when the indicator light uses a single-color light source, the number of pins 21 can be two. As another example, when the indicator light uses a dual-color, tri-color, or more-color light source, the number of pins 21 can be N+1, where N is the number of colors. Of course, depending on the power supply principle of the light source, the relationship between the number of pins 21 and the number of colors can be different, and this is not limited.

[0031] In this embodiment, the fastening hook 12 and the limiting structure 22 prevent the indicator light from separating from the indicator light terminal block by means of hook limiting. For example, the fastening hook 12 is connected to the terminal block housing 10 by a supporting cantilever 13. The first end of the fastening hook 12 is provided with a hook portion 121 protruding into the terminal block housing 10. The hook portion 121 is used to cooperate with the limiting structure 22 on the indicator light 20 to prevent the indicator light 20 from separating from the indicator light terminal block. The fastening hook 12 can be integrally formed with the terminal block housing by the supporting cantilever 13, thereby improving the structural stability.

[0032] See Figure 5 The limiting structure 22 includes a protrusion on the indicator light housing. The protrusion has a first limiting plane for engaging with the fastening hook 12. The first limiting plane extends in a direction perpendicular to the insertion direction of the indicator light. For example, if the insertion direction is vertical, the first limiting plane is horizontal. When the indicator light is inserted into the indicator light terminal block, the hook portion 121 of the fastening hook 12 overlaps the limiting structure 22. The engagement of the limiting structure 22 and the hook portion 121 prevents the indicator light 20 from separating from the indicator light terminal block. In this embodiment, a second limiting plane is provided on the hook portion 121, extending in a direction perpendicular to the insertion direction.

[0033] In some embodiments, the fastening hook assembly includes two fastening hooks 12 distributed at both ends of the same diameter of a circle. To cooperate with the fastening hooks 12, the indicator light's limiting structure 22 includes two protrusions extending away from the indicator light housing. Each protrusion corresponds to one fastening hook 12. To ensure a reliable connection between the indicator light and the indicator light terminal block and prevent separation, the minimum distance between the hook portions 121 of the two fastening hooks 12 is less than the maximum distance between the two protrusions. Thus, after the indicator light is inserted into the indicator light terminal block, when the indicator light is pulled upwards, the fastening hooks 12 can prevent the protrusions from moving upwards, thereby preventing the indicator light from separating from the indicator light terminal block.

[0034] In other embodiments, the fastening hook assembly includes two or more fastening hooks 12, which may be evenly distributed along the same circle. It should be noted that this circle is a hypothetical circle used for ease of description and does not limit the terminal housing to be circular.

[0035] Optionally, to facilitate indicator light insertion and removal when needed, the connection point between the fastening hook 12 and the support cantilever 13 is located between the first and second ends of the fastening hook 12. When the second end of the fastening hook 12 is pressed and moves closer to the terminal housing 10, the first end of the fastening hook 12 moves away from the terminal housing 10. Since the support cantilever 13 has a certain length, the fastening hook 12 can swing to a certain extent. Thus, when the second end of the fastening hook 12 is pressed and moves closer to the terminal housing 10, the first end of the fastening hook 12 moves away from the terminal housing 10, increasing the distance between the multiple fastening hooks 12, facilitating indicator light insertion, and preventing interference between the indicator light's limiting structure 22 and the fastening hook 12 from causing insertion difficulties. After the indicator light is inserted, releasing the second end of the fastening hook 12 causes it to automatically reset, and the hook portion 121 of the first end of the fastening hook 12 moves above the limiting structure 22, thereby preventing the indicator light from separating from the indicator light terminal. In addition, the fastening hook 12 and the limiting structure 22 work together to improve the connection strength between the two.

[0036] Optionally, in order to improve the plugging efficiency, the terminal housing 10 is provided with a first foolproof structure 14, which is used to cooperate with the second foolproof structure 23 provided on the indicator light 20.

[0037] In some examples, such as Figure 3 As shown, the first foolproof structure 14 includes a foolproof groove on the terminal block housing 10, and the second foolproof structure 23 of the indicator light 20 includes a foolproof protrusion. The foolproof groove is used to engage with the foolproof protrusion. When the indicator light is inserted into the indicator light terminal block, the foolproof protrusion is inserted into the foolproof groove. This makes it easy to determine the insertion direction of the indicator light terminal block, thereby improving assembly efficiency and effectively preventing misoperation.

[0038] See also Figure 2 , Figures 6 to 8 The indicator light and the indicator light terminal block are electrically connected via pins 21 and a metal spring clip 11, and the two are plugged into each other, resulting in higher assembly efficiency. The metal spring clip 11 is located inside the terminal block housing 10. To ensure reliable installation of the metal spring clip 11 within the terminal block housing 10, a limiting spring clip 111 is provided on the metal spring clip 11. The metal spring clip 11 is fixedly installed inside the terminal block housing 10 by the limiting spring clip 111. The metal spring clip 11 includes a pin mounting cavity for inserting the pins 21 of the indicator light 20 and making a conductive connection with the pins 21 of the indicator light 20.

[0039] In this embodiment, as Figure 2 and Figure 7As shown, the metal clip spring 11 includes a bottom section 113, a first bending section and a second bending section. The first bending section is disposed on a first side of the bottom section 113, and the second bending section is disposed on a second side of the bottom section 113 opposite to the first side, so as to form a pin mounting cavity.

[0040] The first bending segment in this embodiment includes a vertical portion and a horizontal portion. The vertical portion is connected to the bottom segment 113, and the horizontal portion is parallel to the bottom segment 113. It should be noted that this parallelism is not strict, and processing errors are allowed between the two. Similar to the first bending segment, the second bending segment also includes a vertical portion and a horizontal portion. The vertical portion is used to connect to the bottom segment 113, and the horizontal portion is substantially parallel to the bottom segment 113.

[0041] Optionally, one end of the limiting spring 111 is disposed on the bottom section 113, and the limiting spring 111 extends in a direction away from the bottom section 113. Figure 6 and Figure 2 As shown, a through hole is provided on the bottom section 113, and one end of the limiting spring piece 111 is fixed to one wall of the through hole and extends away from the bottom section 113. A stepped surface is provided in the hole inside the terminal housing 10 for accommodating the metal clamping spring 11. After the metal clamping spring 11 is installed in the hole, the limiting spring piece 111 can be abutted by the stepped surface, thereby preventing it from falling out of the hole.

[0042] Optionally, in order to ensure the reliability of the engagement between the pin 21 and the metal spring 11, and thus ensure reliable conductivity, a pin limiting member 114 that can be elastically deformed is provided in the pin mounting cavity. The pin limiting member 114 includes an insertion guide section. The first end of the insertion guide section is connected to the bottom section 113, and the insertion guide section extends away from the bottom section 113 along the insertion direction of the pin mounting cavity.

[0043] like Figure 2 and Figure 7As shown, the pin limiting member 114 is located within the pin mounting cavity. The pin limiting member 114 includes an insertion guide section and a pull-out guide section, forming a triangular shape. The pin 21 has a pin hole 211. When the pin 21 is inserted into the pin mounting cavity, the insertion guide section guides it, facilitating insertion. Simultaneously, the pin 21 can compress the pin limiting member 114, causing it to deform towards the bottom section 113, thus facilitating further insertion. Once the pin 21 is fully inserted, the pin hole 211 aligns with the highest point of the pin limiting member 114, causing the pin limiting member 114 to partially spring back, thus pressing the pin 21 firmly and limiting its position. When the indicator light needs to be removed, due to the presence of the pull-out section, the pin 21 can easily deform the pin limiting member 114 towards the bottom section 113, facilitating removal. The pin limiting member 114 with this structure not only ensures the reliability of the pin 21 insertion, but also avoids excessive effort when pulling out or inserting.

[0044] Optionally, the metal clamping spring 11 further includes a wire clamping spring 112, which forms a wire mounting cavity. The wire 30 is inserted into the wire mounting cavity and clamped by the wire clamping spring 112. This elastic clamping method enables the connection of the wire 30, making the connection convenient, efficient, and ensuring a reliable connection.

[0045] According to another aspect of this application, an indicator light system is provided, which includes an indicator light 20 and the aforementioned indicator light terminal block. The indicator light 20 includes a limiting structure 22 and a pin 21. The limiting structure 22 includes an outwardly extending limiting protrusion. When the indicator light 20 is plugged into the indicator light terminal block, the pin 21 is inserted into the metal clamp spring 11 and electrically connected to the metal clamp spring 11. The limiting structure 22 cooperates with the fastening hook 12 to prevent the indicator light 20 from separating from the indicator light terminal block.

[0046] The indicator light system's indicator light terminal block uses a metal spring 11 to clamp the wires of the deformable clamping spring 112, which in turn clamps the wires 30. The metal spring 11 is fixed inside the terminal block housing 10 by a limiting spring 111 on it. A fastening hook 12 is provided on the terminal block housing 10, which is integrally formed with the terminal block housing 10. It cooperates with the limiting structure 22 of the indicator light to improve the strength and reliability of the connection between the indicator light terminal block and the indicator light.

[0047] In addition, the terminal block housing 10 is also provided with a foolproof groove, which is used to determine the mating direction of the indicator light terminal block and prevent misoperation. When the indicator light is connected to the indicator light terminal block, the metal pin 21 is inserted into the pin mounting cavity of the metal clamp spring 11, and is abutted by the pin limiting member 114 inside the metal clamp spring 11. At the same time, the fastening hook 12 and the limiting structure 22 prevent detachment. This structure is easy to install, not only avoiding misoperation during connection, but also ensuring reliable contact and adaptability to harsh working environments such as high-frequency vibration. This type of indicator light terminal block helps to improve installation efficiency and installation experience.
