Description
Technical Field
[0001] This utility model relates to the field of electrical auxiliary tools, specifically to an auxiliary operating tool for the moving contact of a Siemens series feeder. Background Technology
[0002] In tobacco processing equipment, Siemens power feeders are widely used as the core component for motor control in automated production lines. While the highly integrated modular design of Siemens power feeders improves equipment compactness and ease of installation, it also limits their maintainability. Specifically, the main contacts are encapsulated within the module; forcibly disassembling them for cleaning or replacement can easily damage the internal structure and insulation components, rendering the entire power feeder unusable. Therefore, traditional manual maintenance methods are not feasible, and companies typically rely on preventative replacement strategies to avoid failures. To scientifically determine replacement cycles, the condition of the main contacts needs to be assessed by measuring their contact resistance; however, existing measurement methods have significant shortcomings.
[0003] Currently, operators typically use conventional multimeters to measure contact resistance, requiring manual pressing of the moving contact on the front of the feeder module to simulate a closed contact state. However, the moving contact is located in a narrow slot on the module panel, necessitating the use of a sharp tool (such as a screwdriver) to apply force to the contact tip. This can easily lead to loosening of the contact's mechanical structure or uneven force application, affecting the accuracy of the measurement results. Furthermore, it is difficult for a single operator to simultaneously press the contact and measure the resistance of the terminals on the back of the module, resulting in low operational efficiency or even measurement failure.
[0004] The aforementioned issues result in insufficient reliability of condition assessments, which may delay replacement timing or cause unnecessary waste of components.
[0005] To solve the above problems, it is necessary to develop a special tool for the main contacts of Siemens feeders that can accurately and stably close the contacts without the need for sharp tools to press them, thus avoiding damage to the mechanical structure of the contacts. Summary of the Invention
[0006] To address the shortcomings of the existing technology, this utility model provides an auxiliary operating tool for the moving contact of Siemens series power supply. By precisely matching the contact actuation device with the moving contact of Siemens series power supply and setting the movement path of the contact actuation device to a fixed value, the moving contact is ensured to close stably, thereby improving the accuracy of the main contact resistance measurement data and overcoming problems such as difficulty in single-person operation and easy measurement errors.
[0007] Specifically, this utility model provides an auxiliary operating tool for the moving contact of a Siemens series power supply, which ensures stable closure of the main contact when measuring the contact resistance of the main contact to assess its state; it includes a contact actuation device adapted to the moving contact of the Siemens series power supply; the movement path of the contact actuation device is set to a fixed value to improve the accuracy of the measurement data.
[0008] Furthermore, the contact actuation device includes: a first contact actuation device and a second contact actuation device, both of which are used to stably bring the moving contacts of the Siemens series feeder to a closed state.
[0009] Furthermore, the first contact actuation device includes: a base, a contact actuation port, and an anti-slip panel;
[0010] The contact actuation port is located below the base, and its shape and inner diameter are adapted to the moving contact of the Siemens series feeder, forming a snap-fit engagement with the moving contact of the Siemens series feeder.
[0011] An anti-slip panel is located on top of the base, and its surface has anti-slip texture to provide sufficient friction, making it easy for operators to push the base.
[0012] Furthermore, the second contact actuation device includes: a contact insertion interface, a limiting plate, a handle, and an actuation block;
[0013] The contact insertion interface is located below the limiting plate. Its shape and inner diameter are adapted to the moving contact of the Siemens series feeder, and it forms a snap-fit engagement with the moving contact of the Siemens series feeder.
[0014] The limit plate is used to limit the insertion depth of the contact socket to avoid damage to the moving contacts of Siemens series feeders due to over-insertion;
[0015] The upper part of the limit plate is fixedly connected to the handle, making it convenient for operators to perform insertion operations;
[0016] The actuating block is located inside the contact insertion interface and has a beveled structure. When the contact insertion interface is engaged with the moving contact of the Siemens series feeder, the beveled surface of the actuating block will abut against the moving contact of the Siemens series feeder as the insertion continues. As the insertion continues, the actuating block uses its beveled structure to apply a continuous pushing force to the moving contact until the moving contact is pushed to the closed state.
[0017] Furthermore, the outer diameter of the contact actuation port is set to a fixed size that matches the slot on the Siemens series power supply module panel, thus limiting the movement path of the first contact actuation device to a fixed value. When the push base moves along the fixed path to the set position, the Siemens series power supply actuation contact can accurately and stably reach the closed state, thereby ensuring that the contact state is consistent each time when measuring the contact resistance of the main contact, and ensuring the accuracy and reliability of the measurement results.
[0018] Furthermore, the outer diameter of the contact plug is set to a fixed size that matches the slot on the Siemens series feeder module panel, while the actuating block is set to a fixed size, so that the stroke of the actuating block pushing the moving contact of the Siemens series feeder is fixed and unique.
[0019] Furthermore, the contact actuation device is made of insulating material to ensure safety during operation.
[0020] Working principle: When the operator uses a conventional multimeter to measure the contact resistance of the contacts, the Siemens series feeder moving contact auxiliary operating tool starts to work.
[0021] Working principle of the first contact actuation device 3: The operator first identifies the moving contact 2 of the Siemens series power supply and the corresponding slot position on the module panel. Holding the first contact actuation device 3 with the anti-slip panel 33, the operator precisely aligns the contact actuation port 32 under the base 31 with the moving contact 2 of the Siemens series power supply. Because the shape and inner diameter of the contact actuation port 32 are adapted to the moving contact 2 of the Siemens series power supply, the two form a stable snap-fit fit. At the same time, the outer diameter of the contact actuation port 32 is a fixed size adapted to the slot of the Siemens series power supply module panel, which is like a preset track for the movement of the device, fundamentally limiting the movement trajectory of the first contact actuation device 3. The operator utilizes the anti-slip texture on the surface of the anti-slip panel 33 to obtain reliable friction and stably push the base 31. During the pushing process, limited by the fixed movement path, the base 31 can only move along a predetermined direction and distance. When the base 31 moves, it drives the contact actuation port 32 to move, which in turn drives the Siemens series feeder moving contact 2 to move, bringing the Siemens series feeder moving contact 2 to the closed state without deviation, at which point the testing work is initiated. After the test is completed, the operator slowly and steadily applies reverse force to the anti-slip panel 33. Because the connection between the base 31 and the contact actuation port 32 is stable and the movement path is fixed and reversible, the base 31 retracts along the predetermined reverse path, bringing the Siemens series feeder moving contact 2 back to its initial position. At this time, pulling the contact actuation port 32 of the base 31 gradually separates it from the Siemens series feeder moving contact 2, and the testing task is successfully completed.
[0022] Working principle of the second contact actuation device 4: The operator holds the handle 43 of the second contact actuation device 4; the operator gradually inserts the contact interface 41 into the slot through the handle 43, and the limiting plate 42 monitors and limits the insertion degree of the contact interface 41 in real time to avoid damage to the moving contact 2 of the Siemens series feeder due to over-insertion. After the contact interface 41 is successfully engaged with the moving contact 2 of the Siemens series feeder, the operator continues to push the handle 43 to perform the insertion operation. As the insertion action continues, the inclined surface of the actuating block 44 inside the contact interface 41 will abut against the moving contact 2 of the Siemens series feeder. As the insertion action continues, the inclined surface of the actuating block 44 applies a continuous pushing force to the moving contact 2 until the moving contact 2 is pushed to the closed state, at which point the detection work is started. After the test, the operator pulls handle 43. Under the pulling force, the contact block 44 gradually separates from the moving contact 2 of the Siemens series power supply, and the contact insertion interface 41 exits the slot along a fixed path. The operator then inserts the contact insertion interface 41 back into the slot. After the contact insertion interface 41 successfully engages with the moving contact 2 of the Siemens series power supply, the operator continues to push handle 43 to perform the insertion operation. As the insertion action continues, the inclined surface of the contact block 44 inside the contact insertion interface 41 will abut against the moving contact 2 of the Siemens series power supply. As the insertion action continues, the contact block 44 uses its inclined surface structure to apply a continuous pushing force to the moving contact 2 until the moving contact 2 returns to its initial position. The operator pulls handle 43, and under the pulling force, the contact block 44 gradually separates from the moving contact 2 of the Siemens series power supply, and the contact insertion interface 41 exits the slot along a fixed path, thus successfully completing the test task.
[0023] Throughout the entire operation, both the first contact actuation device 3 in Scheme 1 and the second contact actuation device 4 in Scheme 2 ensured that the closed state of the Siemens series feeder moving contact 2 remained consistent during each operation. This provided stable and reliable conditions for subsequent measurement of the main contact resistance, effectively guaranteeing the accuracy and reliability of the measurement results. Furthermore, since the contact actuation devices are all made of insulating materials, they effectively isolate any potential current, comprehensively ensuring the safety of operators during operation and preventing accidents caused by electrical reasons. This provides a reliable safety barrier for equipment maintenance and testing.
[0024] Beneficial effects:
[0025] 1. The contact actuation device of this utility model is precisely matched with the moving contact of Siemens series feeders. With a fixed movement path, it ensures that the moving contact can be stably closed during each operation, which greatly reduces the measurement error caused by the difference in contact closure and provides a solid guarantee for the accurate measurement of the contact resistance of the main contact.
[0026] 2. This utility model tool minimizes the interference of human factors on measurement results through a fixed movement path and an automated contact actuation mechanism. Operators only need to follow the established procedures to ensure that the force and movement state of the contact are consistent in each measurement, thereby obtaining more accurate and reliable measurement data.
[0027] 3. Whether the first contact actuation device pushes the base via the anti-slip panel, or the second contact actuation device uses a handle inserted into the contact socket, this utility model is easy for operators to master, effectively reducing operational difficulty, saving operation time, and significantly improving work efficiency.
[0028] 4. This utility model features a simple structure, clear functions, and easy operation. It can be operated independently by a single person, and its ease of use and speed reduce the need for excessive manpower during equipment testing and maintenance, thus saving labor costs. Simultaneously, it reduces the probability of measurement failures, avoiding wasted time and manpower due to repeated measurements, further improving work efficiency. Attached Figure Description

[0043] The technical solution will now be described in detail with reference to the accompanying drawings of the embodiments of this utility model.
[0044] Example 1
[0045] like Figure 2 , 4 As shown, a Siemens series power supply contact auxiliary operating tool includes: a first contact actuation device 3, a base 31, a contact actuation port 32, and an anti-slip panel 33.
[0046] The contact actuation port 32 is located below the base 31. Its shape and inner diameter are adapted to the moving contact 2 of the Siemens series feeder, and it forms a snap-fit engagement with the moving contact 2 of the Siemens series feeder.
[0047] An anti-slip panel 33 is positioned above the base 31 and has anti-slip textures on its surface to provide sufficient friction, making it easy for the operator to push the base 31.
[0048] The outer diameter of the contact actuation port 32 is set to a fixed size that matches the slot 12 on the Siemens series power supply module panel 11, so that the moving path of the first contact actuation device 3 is limited to a fixed value; when the push base 31 moves along the fixed path to the set position, the Siemens series power supply actuation contact 2 can accurately and stably reach the closed state, thereby ensuring that the contact state is consistent each time when measuring the contact resistance of the main contact, and ensuring the accuracy and reliability of the measurement results.
[0049] The first contact actuation device 3 is made of insulating material to ensure safety during operation. For example... Figure 3As shown, when the operator uses a conventional multimeter to measure the contact resistance of the contacts, the first contact actuation device 3 of the Siemens series power supply moving contact auxiliary operating tool starts to work. The operator first identifies the Siemens series power supply moving contact 2 and the corresponding slot 12 position on the module panel 11. Holding the first contact actuation device 3 with the anti-slip panel 33, the operator precisely aligns the contact actuation port 32 under the base 31 with the moving contact 2. Because the shape and inner diameter of the contact actuation port 32 are adapted to the Siemens series power supply moving contact 2, a stable snap-fit engagement is formed. Simultaneously, the outer diameter of the contact actuation port 32 is a fixed size adapted to the slot 12 of the Siemens series power supply module panel 11, which is like pre-setting a track for the movement of the device, fundamentally limiting the movement trajectory of the first contact actuation device 3. The operator utilizes the anti-slip texture on the surface of the anti-slip panel 33 to obtain reliable friction and stably push the base 31. During the pushing process, limited by the fixed movement path, the base 31 can only move along a predetermined direction and distance. When the base 31 moves, it drives the contact actuation port 32 to move, which in turn drives the Siemens series feeder moving contact 2 to move, bringing the Siemens series feeder moving contact 2 to the closed state without deviation, at which point the testing work is initiated. After the test is completed, the operator slowly and steadily applies reverse force to the anti-slip panel 33. Because the connection between the base 31 and the contact actuation port 32 is stable and the movement path is fixed and reversible, the base 31 retracts along the predetermined reverse path, bringing the Siemens series feeder moving contact 2 back to its initial position. At this time, pulling the contact actuation port 32 of the base 31 gradually separates it from the Siemens series feeder moving contact 2, and the testing task is successfully completed.
[0050] Example 2
[0051] like Figure 5 , 6 As shown, the difference from Embodiment 1 is that the Siemens series power supply contact auxiliary operation tool of Embodiment 2 includes: a second contact actuation device 4, a contact insertion interface 41, a limiting plate 42, a handle 43, and an actuation block 44.
[0052] The contact insertion interface 41 is located below the limiting plate 42. Its shape and inner diameter are adapted to the moving contact 2 of the Siemens series feeder, and it forms a snap-fit engagement with the moving contact 2 of the Siemens series feeder.
[0053] The limiting plate 42 is used to limit the insertion depth of the contact insertion interface 41 to avoid damage to the moving contact 2 of the Siemens series feeder due to excessive insertion;
[0054] The upper part of the limiting plate 42 is fixedly connected to the handle 43, which facilitates the operator to perform the insertion operation;
[0055] like Figure 10As shown, the actuating block 44 is disposed inside the contact insertion interface 41 and has a beveled structure. When the contact insertion interface 41 is engaged with the moving contact 2 of the Siemens series feeder, the beveled surface of the actuating block 44 will abut against the moving contact 2 of the Siemens series feeder during the continued insertion process. As the insertion action continues, the actuating block 44 uses its beveled structure to apply a continuous pushing force to the moving contact 2 until the moving contact 2 is pushed to the closed state.
[0056] The outer diameter of the contact plug interface 41 is set to a fixed size that fits the slot 12 on the panel 11 of the Siemens series feeder module. At the same time, the actuating block 44 is set to a fixed size, so that the stroke of the actuating block 44 pushing the moving contact 2 of the Siemens series feeder is fixed and unique.
[0057] The second contact actuation device 4 is made of insulating material to ensure safety during operation.
[0058] like Figure 7-9 As shown, when the second contact actuation device 4 is working, the operator holds the handle 43 of the second contact actuation device 4. The operator inserts the contact interface 41 into the slot 12 step by step through the handle 43. The limiting plate 42 monitors and limits the insertion degree of the contact interface 41 in real time to avoid damage to the Siemens series feeder moving contact 2 due to over-insertion. After the contact interface 41 and the Siemens series feeder moving contact 2 are successfully engaged, the operator continues to push the handle 43 to perform the insertion operation. As the insertion action continues, the inclined surface of the actuating block 44 inside the contact interface 41 will abut against the Siemens series feeder moving contact 2. As the insertion action continues, the inclined surface of the actuating block 44 applies a continuous pushing force to the moving contact 2 until the moving contact 2 is pushed to the closed state, at which point the detection work is started. After the test, the operator pulls handle 43. Under the pulling force, the contact block 44 gradually separates from the moving contact 2 of the Siemens series power supply, and the contact insertion interface 41 exits the slot 12 along a fixed path. The operator then inserts the contact insertion interface 41 into the slot 12 in the opposite direction. After the contact insertion interface 41 and the moving contact 2 of the Siemens series power supply are successfully engaged, the operator continues to push handle 43 to perform the insertion operation. As the insertion action continues, the inclined surface of the contact block 44 inside the contact insertion interface 41 will abut against the moving contact 2 of the Siemens series power supply. As the insertion action continues, the contact block 44 uses its inclined surface structure to apply a continuous pushing force to the moving contact 2 until the moving contact 2 returns to its initial position. The operator pulls handle 43. Under the pulling force, the contact block 44 gradually separates from the moving contact 2 of the Siemens series power supply, and the contact insertion interface 41 exits the slot 12 along a fixed path, thus successfully completing the test task.
[0059] Throughout the entire operation, both the first contact actuation device 3 and the second contact actuation device 4 of Scheme 2 ensured that the closed state of the Siemens series feeder moving contact 2 was consistent during each operation, providing stable and reliable conditions for subsequent measurement of the main contact resistance, and effectively guaranteeing the accuracy and reliability of the measurement results.
