[0035] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0036] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and 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, and therefore should not be construed as a limitation of this application.

[0037] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0039] Currently, the steel wires in synchronous belts are connected to external wiring via welding, which in turn connects to external circuits. However, this connection process requires multiple manual steps, including steel wire pretreatment, soldering, and post-processing inspection. Connecting a single belt is time-consuming and relies on skilled welders. The connection between the steel wires and external circuits is also challenging and time-consuming. Furthermore, maintaining this connection is difficult; solder joints are prone to failure due to vibration and corrosion, resulting in short maintenance cycles and high costs. Additionally, the applicable scenarios are limited; it is unsuitable for confined spaces and sanitary environments, posing safety hazards such as burns from high temperatures and electrical fires.

[0040] To address the aforementioned problems, this application provides an electrical connection assembly and a synchronous belt unit. The electrical connection assembly includes a housing, a circuit board, and a connector. The housing is mounted on the synchronous belt, and the circuit board is mounted inside the housing. An external connection cable connector can pass through a wiring hole in the housing and electrically connect to a terminal block on the circuit board. One end of the connector is electrically connected to the circuit board, and the other end forms a plug-in portion. When the housing is mounted on the synchronous belt, the plug-in portion is inserted into the synchronous belt and makes conductive contact with the steel wires in the synchronous belt. Thus, compared to welding, the connection between the steel wires in the synchronous belt and the external circuit is easier and faster.

[0041] Furthermore, the connection between the electrical connection assembly and the steel wire in the synchronous belt is more reliable, which helps extend maintenance cycles. It also allows for the reuse of the connection wire between the steel wire and external circuits, reducing material waste and downtime costs. The electrical connection assembly can connect to the synchronous belt in confined spaces without the risk of welding slag contamination, making it suitable for narrow spaces and sanitary environments. It avoids the risks of burns and fumes associated with welding, eliminates electrical fire hazards, and improves safety.

[0042] The specific structure of the electrical connection component and synchronous belt unit provided in the embodiments of this application will be described below with reference to the accompanying drawings.

[0043] Reference Figures 1 to 5 As shown, this application embodiment provides an electrical connection assembly, including a housing 100, a circuit board 200, and a connector 300. The housing 100 is configured to be mounted on a timing belt 500, and a wiring hole 111 is provided on the housing 100. The wiring hole 111 can be integrally formed on the side wall of the housing 100, and the connector of the external connection wire can extend into the interior of the housing 100 through the wiring hole 111.

[0044] The circuit board 200 is mounted inside the housing 100. The circuit board 200 has terminals 210 aligned with the wiring holes 111. Schematic, the housing 100 has an internal receiving cavity into which the circuit board 200 can be mounted. External connecting wires can pass through the wiring holes 111 and connect to the terminals 210 to establish an electrical connection between the wires and the circuit board 200. Mounting the circuit board 200 within the housing 100 also provides protection for it. In one possible implementation, the circuit board 200 can be secured to the housing 100 with screws after being placed inside.

[0045] One end of the connector 300 is electrically connected to the circuit board 200, and the other end of the connector 300 forms a connector 310. The connector 310 extends out of the housing 100 and is configured to be inserted into the timing belt 500 and make conductive contact with the steel wire in the timing belt 500.

[0046] The connector 300 can be made of metal and enables electrical connection between the circuit board 200 and the steel wires in the timing belt 500. Optionally, the connector 310 can be a sheet-like structure, with a pointed end away from the circuit board 200 to allow insertion into the timing belt 500. The connector 300 abuts against the circuit board 200. As the housing 100 connects to the timing belt 500, the connector 310 gradually inserts into the timing belt 500. Once connected, the connector 310 makes conductive contact with the steel wires in the timing belt 500. The electrical connection assembly presses the connector 300 tightly against the built-in steel wires of the timing belt 500, creating a conductive path through "metal-to-metal contact." Notably, connecting the steel wires in the timing belt 500 to external connecting lines via the electrical connection assembly allows for both power transmission to power the equipment and communication signal transmission.

[0047] It should be noted that the steel wire in the synchronous belt 500 can be connected to two external circuits through two electrical connection components, realizing the transmission of power / communication signals from "external circuit - electrical connection component - steel wire - electrical connection component - external circuit", which can be completed without welding.

[0048] In related technologies, the connection between the steel wire and the external connecting line in the synchronous belt 500 requires multiple manual processes such as steel wire pretreatment, soldering, and post-processing inspection. The electrical connection of a single synchronous belt 500 takes 12 to 18 minutes and requires professional welders to avoid incomplete or missing solder joints.

[0049] In the electrical connection assembly provided in this embodiment, the steel wire in the synchronous belt 500 is connected to the external connecting line through the electrical connection assembly, eliminating the need for welding, reducing manual intervention steps, and lowering the connection difficulty. The connection time between the steel wire in the synchronous belt 500 and the external connecting line can be shortened to the minute level, making it suitable for mass production scenarios.

[0050] Furthermore, in related technologies, there are issues of poor reliability and high maintenance costs between the steel wires and external connecting wires in the synchronous belt 500. This is mainly because welded joints are prone to cracking due to vibration and environmental corrosion, requiring downtime for maintenance every 2-3 months on average, and the connecting wires cannot be reused when replacing the synchronous belt 500.

[0051] The electrical connection assembly provided in this embodiment does not require welding with the synchronous belt 500. It has high shock resistance and corrosion resistance, which can extend the maintenance cycle to 1-2 years. At the same time, it can realize the reuse of the connection wire and does not require the consumption of additional consumables such as solder, thus reducing material consumption and downtime costs.

[0052] Existing technologies cannot accommodate welding tools in confined spaces (gap < 30mm), and solder joints are prone to detachment under high-frequency vibration (> 10Hz). Furthermore, there is a risk of welding slag contamination in sanitary environments (food / pharmaceutical). The electrical connection assembly provided in this embodiment can be installed on a synchronous belt 500 in confined spaces, and the circuit board 200 of the electrical connection assembly is reliably electrically connected to the steel wire in the synchronous belt 500 without the problem of solder joint detachment. It is suitable for confined spaces, high-frequency vibration environments, and sanitary environments, overcoming limitations imposed by these limitations.

[0053] The electrical connection component provided in this embodiment can also solve the problem of safety hazards in operation and use, avoid the health risks of burns and rosin fumes caused by welding, and avoid local overheating and fire caused by poor welding, thus improving safety.

[0054] In one embodiment, such as Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the connector 300 is provided with two connector portions 310, which are arranged at intervals along the extension direction of the synchronous belt 500.

[0055] Understandably, when the two connectors 310 of the connector 300 are respectively inserted into the timing belt 500, the two connectors 310 of the connector 300 can be electrically connected to two different positions of the steel wire. This embodiment does not limit the specific size of the interval between the two connectors 310; those skilled in the art can set it according to actual needs.

[0056] In this embodiment, the two plug-in portions 310 of the plug-in 300 can serve as backups for each other. That is, when one plug-in portion 310 is not electrically connected to the steel wire in the synchronous belt 500, the other plug-in portion 310 can also be electrically connected to the steel wire in the synchronous belt 500, thereby ensuring the reliability of the electrical connection between the circuit board 200 and the steel wire in the synchronous belt 500.

[0057] In other embodiments, the number of plug-in portions 310 may also be multiple, such as three or four, etc., and is not limited to one.

[0058] In one embodiment, such as Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, there are two connectors 300, and the two connectors 300 are arranged at intervals along the width direction of the synchronous belt 500.

[0059] Those skilled in the art will understand that the synchronous belt 500 has multiple steel wires, which are spaced apart along the width direction of the synchronous belt 500. When the housing 100 is installed on the synchronous belt 500, the two connectors 300 are electrically connected to the corresponding steel wires through the connectors 310.

[0060] With the above configuration, the two connectors 300 can be used to transmit power and transmit communication signals respectively, that is, the electrical connection assembly can be used to transmit power and communication signals simultaneously.

[0061] In one embodiment, the electrical connection assembly further includes a cover (not shown). The cover is located on one side of the housing 100 and is fixedly connected to it. The insertion portion 310 is located on the side of the housing 100 facing the cover, and the cover and housing 100 are configured to clamp the timing belt 500.

[0062] Schematic, the cover and housing 100 are located on opposite sides of the synchronous belt 500. After the cover and housing 100 are respectively positioned on both sides of the synchronous belt 500, the insertion portion 310 of the connector 300 is gradually inserted into the synchronous belt 500 as the cover and housing 100 are fixed. In one possible implementation, the cover and housing 100 can be fixed by a snap-fit ​​connection.

[0063] With the above settings, the housing 100 can be reliably installed on the synchronous belt 500, thereby ensuring the reliability of the electrical connection between the circuit board 200 in the housing 100 and the steel wire in the synchronous belt 500.

[0064] In other embodiments, the housing 100 may also be mounted on the timing belt 500 by a snap-fit ​​connection, which is not the only one.

[0065] In a specific embodiment, such as Figures 2-4 As shown, the housing 100 includes a cover 110 and a fixing member 120. The cover 110 is provided with a receiving cavity, and the circuit board 200 and the fixing member 120 extend into the receiving cavity respectively.

[0066] When the housing 100 is mounted on the timing belt 500, the opening of the receiving cavity faces the timing belt 500. For example, the fixing member 120 can be a plate-like structure, the shape of which can match the shape of the opening of the receiving cavity. The fixing member 120 is located on the side of the circuit board 200 facing the opening of the receiving cavity, and the fixing member 120 can seal the opening of the receiving cavity, preventing the circuit board 200 from detaching from the receiving cavity.

[0067] Along the thickness direction of the circuit board 200, the circuit board 200 is clamped between the cover 110 and the fixing member 120, and the cover 110 is provided with wiring holes 111.

[0068] For example, a support portion protrudes from the inner wall of the receiving cavity facing the fixing member 120, and the side of the circuit board 200 opposite to the fixing member 120 abuts against the support portion. By clamping the circuit board 200 with the fixing member 120 and the cover 110, movement of the circuit board 200 relative to the cover 110 along its own thickness direction can be prevented. Optionally, after the fixing member 120 is placed in the receiving cavity, screws can be used to lock the fixing member 120 to the cover 110. Figure 2 As shown, the wiring hole 111 can be opened on the side wall of the cover 110.

[0069] The fixing member 120 is provided with a through hole 121, and the plug-in member 300 is provided through the through hole 121. The shape of the through hole 121 can match the shape of the plug-in member 300 facing the synchronous belt 500. When the fixing member 120 is installed in the receiving cavity, the plug-in part 310 of the plug-in member 300 extends out from the through hole 121.

[0070] The circuit board 200 can be confined within the receiving cavity of the housing 110 by the fastener 120, ensuring that after the housing 100 is installed on the timing belt 500, the plug part 310 of the plug 300 can be inserted into the timing belt 500 and electrically connected to the steel wire in the timing belt 500.

[0071] In a more specific embodiment, such as Figures 2-4 As shown, a limiting groove 122 is provided on the side of the fastener 120 away from the circuit board 200. The limiting groove 122 extends along the extension direction of the timing belt 500, and the two opposite sidewalls of the limiting groove 122 are used to abut against the timing belt 500 respectively.

[0072] The limiting groove 122 includes a bottom wall and two opposing side walls. When the housing 100 is installed on the synchronous belt 500, the synchronous belt 500 extends into the limiting groove 122, and the two side walls of the limiting groove 122 abut against the two sides of the synchronous belt 500 in the width direction. Through the cooperation between the limiting groove 122 and the synchronous belt 500, the housing 100 can be limited to the synchronous belt 500, preventing the housing 100 from moving relative to the synchronous belt 500 in the width direction of the synchronous belt 500. The housing 100 also integrates guiding and protective functions, realizing the integration of mechanical positioning, electrical connection and environmental protection. The above configuration can further improve the reliability of the connection between the electrical connection components and the synchronous belt 500, improve the shock resistance of the electrical connection between the steel wire in the synchronous belt 500 and the external connecting wire, extend the maintenance cycle, and adapt to high-frequency vibration scenarios.

[0073] It is worth mentioning that the electrical connection assembly can be fitted with different fasteners 120 so that the width of the upper limit groove 122 of the fastener 120 matches the width of the synchronous belt 500. In this way, the electrical connection assembly can be adapted to synchronous belts 500 of different sizes, thus improving the versatility of the electrical connection assembly.

[0074] In a more specific embodiment, such as Figure 3 and Figure 4 As shown, the bottom of the limiting groove 122 is provided with a protruding ridge 123, which is configured to extend into the space between two adjacent teeth of the synchronous belt 500.

[0075] It is worth mentioning that the bottom of the limiting groove 122 is located on the side of the synchronous belt 500 where the teeth are located. A protruding rib 123 is disposed on the bottom wall of the limiting groove 122. The protruding rib 123 can extend along the width direction of the limiting groove 122. When the protruding rib 123 extends between two teeth of the synchronous belt 500, it can restrict the movement of the housing 100 along the extension direction of the synchronous belt 500. There can be one or more protruding ribs 123. When there are multiple protruding ribs 123, they are spaced apart along the length direction of the limiting groove 122. Each protruding rib 123 can be integrally formed on the bottom of the limiting groove 122.

[0076] In this embodiment, the engagement between the protruding ridge 123 and the teeth of the synchronous belt 500 enables the housing 100 to be quickly positioned, improving the connection efficiency between the electrical connection component and the synchronous belt 500. It also allows the insertion part 310 of the plug 300 to be inserted into the synchronous belt 500 between the two teeth of the synchronous belt 500, facilitating the connection between the electrical connection component and the synchronous belt 500.

[0077] In one possible implementation, the housing 100 is fastened to the cover by fasteners 400, which pass through the cover 110, the circuit board 200 and the fasteners 120 respectively.

[0078] For example, the number of fasteners 400 can be four, with each fastener 400 located at one of the four corners of the housing 100. It is understood that the fasteners 400 confine the circuit board 200 and the fixing member 120 within the receiving cavity of the housing 110, preventing movement of the circuit board 200 and the fixing member 120 relative to the housing 110 in a plane parallel to the circuit board 200. When the housing 100 is mounted on the timing belt 500, the reliability of the electrical connection between the circuit board 200 and the steel wires in the timing belt 500 can be further ensured.

[0079] In one embodiment, such as Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the connector 300 also includes a main body 320 and an electrical connection part 330, with the connector 310 and the electrical connection part 330 respectively disposed on opposite sides of the main body 320. The electrical connection part 330 passes through the circuit board 200 and is electrically connected to the circuit board 200, while the main body 320 abuts against the circuit board 200.

[0080] The insertion part 310, the main body part 320, and the electrical connection part 330 can be formed into a single piece using an integral molding process. The electrical connection part 330 can be a columnar structure, and there can be one or more of them. The circuit board 200 can be provided with vias, and the electrical connection part 330 can pass through the vias and be electrically connected to the vias.

[0081] Indicatively, the cross-sectional area of ​​the main body 320 is larger than that of the plug-in part 310. After the main body 320 abuts against the circuit board 200, it can increase the contact area between the plug-in part 300 and the circuit board 200. During the connection process between the housing 100 and the timing belt 500, the circuit board 200 can push the main body 320 of the plug-in part 300 so that the plug-in part 310 of the plug-in part 300 is inserted into the timing belt 500, and the circuit board 200 will not be damaged.

[0082] This application embodiment also provides a synchronous belt unit, including a synchronous belt 500 and the above-mentioned electrical connection component, wherein the plug portion 310 of the electrical connection component is inserted into the synchronous belt 500 and makes conductive contact with the steel wire in the synchronous belt 500.

[0083] The synchronous belt unit provided in this embodiment is easy to assemble and quick to complete due to the use of the aforementioned electrical connection components. Furthermore, the synchronous belt unit has high electrical connection reliability, enabling it to reliably transmit power and communication signals.

[0084] The synchronous belt unit provided in this embodiment boasts advantages such as weldless connections, high reliability, and wide adaptability to various scenarios, offering broad application prospects. In the field of intelligent logistics, it adapts to sorting lines and AGVs (Automated Guided Vehicles), solving vibration and maintenance issues. In intelligent manufacturing, it supports flexible production lines, adapting to confined spaces and cleanliness requirements. In the food and pharmaceutical industries, it meets hygiene standards, allowing for high-temperature sterilization without pollution. In the medical equipment field, it adapts to the confined spaces of precision instruments, ensuring safety. In outdoor new energy scenarios, it is resistant to moisture and dust, reducing outdoor maintenance. In rail transit auxiliary equipment, it minimizes downtime and adapts to the limited maintenance space requirements.

[0085] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0086] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
