Description

Technical Field

[0001] This invention belongs to the field of aero-engine vibration measurement, and specifically relates to a special wiring tool for vibration sensors. Background Technology

[0002] In the field of aero-engine vibration measurement, sensors and vibration measurement cables are commonly used to collect raw vibration signals. The vibration measurement cable consists of a cable and an L5 male connector.

[0003] The L5 male connector includes a pin, a housing nut, and other components. The pin, located inside the housing nut, is used to connect to the internal terminals of the sensor for power supply and signal transmission. The housing nut, usually made of metal, is used to secure the cable to the sensor connector and provides a non-slip texture for gripping the connector.

[0004] L5 male connector (10-32UNF) Figure 1 As shown, when connecting to the sensor, insert the pin into the corresponding socket of the sensor, and then rotate the housing nut to engage with the external thread of the sensor; generally, it is tightened manually or by using needle-nose pliers to tighten the housing nut to the external thread of the sensor.

[0005] Tightening manually or using needle-nose pliers presents the following problems: 1. Inefficient: especially in large-scale installations or space-constrained situations.

[0006] 2. Inconsistent torque: Manual force is difficult to control precisely, which may result in a connection that is too loose (poor contact, easy to loosen), making it easy to loosen during the test; or too tight (damaging the connector thread or sealing ring), causing the cable to twist, generate spring force, or the thread to come off during the test, resulting in significant signal interference during the test.

[0007] 3. Prone to slipping and damage: The smooth surface of the outer shell nut or the small operating space can easily cause the tool to slip, which may scratch the surface of the nut or damage the cable.

[0008] 4. Cable Twisting: If the cable is not effectively secured when tightening the housing nut, it may cause the internal conductors or shielding layer of the cable to twist, damaging the cable at the rear end of the connector, affecting signal quality and long-term reliability; or it may generate stress, causing the threads to come off during the test and the connection to loosen.

[0009] 5. Difficult to operate at high temperatures: If the cable is replaced temporarily during the test, the temperature is high, and manual replacement is difficult and there is a risk of burns.

[0010] 6. Using excessive force with needle-nose pliers can cause problems such as cracking of the outer shell nut, deformation and damage of the threads, and failure of the anti-slip texture.

[0011] In view of this, the present invention is hereby proposed. Summary of the Invention

[0019] Furthermore, the motor is a miniature planetary DC geared motor.

[0020] Furthermore, the wire clamping mechanism includes a wire clamp and a second spring, with multiple wire clamps connected to the wiring slot via a second spring.

Detailed Implementation

[0029] The following description provides many different embodiments or examples for implementing various features of the invention. The elements and arrangements described in the specific examples below are only for concise expression of the invention and are merely examples, not intended to limit the invention.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] This embodiment provides a dedicated wiring tool for a vibration sensor 120, such as... Figure 2 , Figure 3 and Figure 4As shown, the device includes a wiring tool body 10, which has a wiring groove 11 extending through both ends. A wire clamping mechanism 20 and a tightening mechanism 30 are provided in the wiring groove 11. The wire clamping mechanism 20 is used to fix the cable 110 of the L5 male connector, and the tightening mechanism 30 is used to fix the outer shell nut 90 of the L5 male connector. After the pin 100 of the L5 male connector is connected to the sensor 120, the tightening mechanism 30 drives the outer shell nut 90 to rotate and connect with the thread on the sensor 120.

[0032] In some embodiments, such as Figure 2 , Figure 3 As shown, the wiring tool body 10 has a U-shaped columnar structure, which provides a central operating space (i.e., wiring groove 11) to accommodate the cable 110 and the outer shell nut 90.

[0033] In some embodiments, such as Figure 5 As shown, the tightening mechanism 30 includes a drive rotation structure 31 and a first spring 32. Multiple drive rotation structures 31 are circumferentially distributed within the wiring groove 11, and multiple sets of drive rotation structures 31 are connected to the wiring groove 11 via the first spring 32. The first spring 32 enables the drive rotation structure 31 to adapt to its radial position, accommodating different L5 male connectors and sensor 120 connections. Furthermore, during the connection process, it ensures that the force exerted by the drive rotation structure 31 on the housing nut 90 is sufficiently large, thereby better driving the housing nut 90 to rotate and improving the connection effect between the L5 male connector and sensor 120.

[0034] In some embodiments, such as Figure 5 As shown, the multiple drive rotation structures 31 are evenly distributed. It should be noted that "evenly distributed" can be understood as being evenly distributed only circumferentially on the wall surface of the wiring slot 11. By evenly arranging the drive rotation structures 31, the force on the housing nut 90 is made more uniform, thereby improving the connection effect between the L5 male connector and the sensor 120.

[0035] In some embodiments, the wiring tool body 10 is provided with a cavity. By providing a cavity in the wiring tool body 10, on the one hand, the weight of the entire tool can be reduced, which not only avoids material waste, but also makes it lighter and easier to use; on the other hand, by providing a cavity, structures such as circuit board 40 and battery 50 can be installed inside it.

[0036] In some embodiments, combined with Figure 2 , Figure 5As shown, the wiring groove 11 has a first guide hole communicating with the cavity. The first guide hole guides the drive rotation structure 31, which is connected to the wall of the cavity via a first spring 32. This design allows a portion of the tightening mechanism 30 to be located within the cavity, making the entire tool structure more compact. Simultaneously, it restricts the tightening mechanism 30, preventing positional shift when it acts on the housing nut 90 and preventing the first spring 32 from twisting. This improves connection efficiency and extends the tool's lifespan. Preferably, the first guide hole is adapted to the shape of the drive rotation structure 31.

[0037] In some embodiments, a first movable groove is provided inside the wiring tool body 10, the first movable groove communicating with the first guide hole, and the first movable groove further serves to guide the tightening mechanism. It should be noted that the first movable groove may be a further improvement of the wiring tool body 10 with a cavity, or the wiring tool body 10 without a cavity may have the first movable groove.

[0038] In some embodiments, such as Figure 5 As shown, the drive rotation structure 31 includes a rotating wheel 311 and a motor 312. The motor 312 is connected to the wiring groove 11 via the first spring 32. The output shaft of the motor 312 is connected to the axial end of the rotating wheel 311. The circumference of the rotating wheel 311 acts on the housing nut 90. For example, as... Figure 5 As shown, three drive rotation structures 31 are provided.

[0039] In some embodiments, the circumference of the rotating wheel 311 (i.e., the working surface: the contact surface with the housing nut 90) is machined with anti-slip texture; by setting the anti-slip texture, the friction with the housing nut 90 is increased, ensuring effective torque transmission. For example, the anti-slip texture can be knurled, meshed, serrated, etc.

[0040] In some embodiments, the motor 312 is a miniature planetary DC geared motor 312. The planetary gear structure provides high torque output and high transmission efficiency. The DC motor 312 is easy to power and control (forward and reverse rotation, start and stop) by the battery 50; forward and reverse rotation can realize the connection and disconnection of the sensor 120 and the L5 male connector. For example, the miniature planetary DC geared motor 312 is a 10mm miniature planetary DC geared motor 312, using a 10mm diameter specification to ensure miniaturization.

[0041] In some embodiments, such as Figure 5As shown, the cable clamping mechanism 20 includes a cable clamp 21 and a second spring 22. Multiple cable clamps 21 are connected to the wiring slot 11 via a second spring 22. The second spring 22 enables the cable clamp 21 to adapt to its radial position, accommodating cables 110 of different sizes and ensuring the cable 110 is securely held within the clamp 21. This effectively prevents the cable 110 from twisting during tightening of the nut, protecting the internal structure of the cable 110.

[0042] In some embodiments, the clamping surface of the cable clamp 21 is provided with a soft material to increase friction and prevent damage to the cable 110. For example, the soft material is rubber.

[0043] In some embodiments, combined with Figure 2 , Figure 5 The wiring groove 11 has a second guide hole that communicates with the cavity of the wiring tool body 10. The second guide hole is used to guide the wire clamp 21. The wire clamp 21 is connected to the wall of the cavity through the second spring 22.

[0044] In some embodiments, a second movable groove is provided inside the wiring tool body 10, and the first movable groove communicates with the second guide hole. The second movable groove further serves to guide the wire clamp 21. It should be noted that the second movable groove can be a further improvement of the wiring tool body 10 with a cavity, or it can be provided in the wiring tool body 10 without a cavity.

[0045] In some embodiments, such as Figure 5 As shown, the wiring tool body 10 is equipped with a circuit board 40 and a battery 50. The battery 50 is connected to the circuit board 40, and the circuit board 40 is connected to the tightening mechanism 30. The built-in battery 50 and circuit board 40 ensure the portability and ease of use of the tool, significantly improving the efficiency, quality, and reliability of wiring the sensor 120 cable 110.

[0046] The circuit board 40 integrates power management, battery 50 charging, voltage regulation, and current distribution functions. The battery 50 group is first connected to the circuit board 40, which distributes power to drive multiple motors 312. The circuit board 40 also includes a charging port to support external power supply for charging the battery 50 group. The battery 50 adopts a U-shaped structure layout, similar to the battery 50 design of a power bank, to fit the U-shaped shell of the tool. The battery 50 group consists of multiple battery 50 units connected in series or parallel, providing a stable DC power supply.

[0047] For example, in a structure that includes a circuit board 40 and a battery 50, such as Figure 4 , Figure 5As shown, a power indicator light 70 and a power button 80 are also provided; the power indicator light 70 is used to indicate the power level of the battery 50; the power button 80 is used to control the connection and disconnection of the circuit between the battery 50 and the motor 312. When the circuit is connected, the motor 312 operates; when the circuit is disconnected, the motor 312 stops. Further, as... Figure 4 As shown, by setting an independent forward and reverse switch to switch the direction of current, the forward and reverse rotation of motor 312 can be controlled.

[0048] It should be noted that structures without circuit board 40 and battery 50 should also be within the scope of protection of this invention. In use, the motor 312 is powered by a power cord to drive its rotation. For example,... Figure 6 As shown, the battery 50 can also be externally mounted and directly connected to the motor 312 to power and drive the motor 312 to rotate.

[0049] Combination Figure 7 As shown, this embodiment illustrates the method of using the dedicated wiring tool: S101: Ensure the tool has sufficient power. When the power is above 50%, the power indicator light 70 will be green; when the power is between 20% and 50%, the power indicator light 70 will be yellow; when the power is below 20%, the power indicator light 70 will be red.

[0050] S102: Align the portion of cable 110 that needs to be connected with cable 110 and push it into cable clamp 21. Cable clamp 21 is squeezed inward and its internal spring provides clamping force to firmly clamp and fix cable 110 and prevent it from twisting.

[0051] S103: Align the outer shell nut 90 that needs to be tightened with and insert it between the three rotating wheels 311.

[0052] S104: The outer surface of the outer shell nut 90 will press the three rotating wheels 311 inward. The rotating wheels 311 (together with their motors 312) move inward in their respective first guide holes, compressing their respective first springs 32. The rebound force generated by the first springs 32 makes the three rotating wheels 311 with anti-slip textures press evenly and tightly against the outer circumferential surface of the outer shell nut 90 from three directions.

[0053] S105: Connect pin 100 to the sensor 120 connector.

[0054] S106: Press the power button 80, and the three motors 312 will start synchronously.

[0055] S107: The rotation of the rotating wheel 311 drives the housing nut 90 to rotate and tighten onto the sensor 120 connector.

[0056] S108: After the outer shell nut 90 is tightened to the correct position, release the power button 80, and the three motors 312 will stop rotating.

[0057] In some embodiments, such as Figure 8 As shown, the axial end of the wiring tool body 10 is also provided with a guide 130, which is used to support and guide the sensor 120 connector. By cooperating with the sensor 120 through the guide 130, the pin 100 of the L5 male connector can be conveniently and accurately inserted into the sensor 120 socket, thereby improving wiring efficiency.

[0058] In some embodiments, combined with Figure 2 , Figure 3 , Figure 5 and Figure 8 As shown, the tightening mechanism 30 is located at the end of the wiring slot 11.
