Description

Technical Field

[0001] This application relates to the field of equipment maintenance technology, and in particular to a novel repair tool. Background Technology

[0002] In the field of mechanical repair tools, with the continuous development and upgrading of electronic products, the demand for repairing internal components is increasing. Connectors, terminals, and other parts in various electronic products may malfunction or require replacement during use, which places higher demands on the functionality and performance of repair tools. Efficient, accurate, and safe repair tools can improve repair efficiency, reduce repair costs, and minimize secondary damage to products, which is crucial for ensuring product quality and lifespan.

[0003] In traditional rework operations, terminal repair mainly focuses on pin removal. Conventional rework tools typically only have pin removal functionality. When repairing terminal springs is required, due to a lack of specialized tools, operators often resort to unprofessional methods. For example, many operators will use their fingernails to pry open the pressed-down springs. Some operators may use rudimentary needle-like tools to try and adjust the spring's position, but these tools are mostly not specifically designed for this purpose and are very inconvenient to use. Additionally, some repair personnel will use general-purpose tools like tweezers, but the size and shape of tweezers may not be well-suited for repairing terminal springs.

[0004] Traditional repair tools have significant limitations, only providing PIN removal functionality and failing to address the repair needs of the terminal spring latch after PIN removal. After PIN removal, the terminal spring latch is pressed down; if it's not pried up, the connector cannot lock the terminal, causing the product to malfunction. Using unprofessional methods such as fingernails, rudimentary needle-like tools, or tweezers to repair the terminal spring latch is not only difficult and inefficient but also poses significant safety risks, potentially injuring operators and causing secondary damage to the terminals and connectors. Utility Model Content

[0005] To address the issue that traditional rework tools can no longer fulfill the PIN removal function while meeting the repair needs of terminal spools, requiring manual operation and increasing complexity and risk, this application provides a novel rework tool.

[0006] The novel repair tool provided in this application adopts the following technical solution: A novel rework tool includes a body, a rework needle, and a telescopic device. The body has a chamber for the rework needle to slide through. A tube is integrally formed on the body. A barb is formed on the end of the rework needle. A gap is formed between the barb and the tube. The tube is connected to the chamber. The telescopic device is installed at the end of the rework needle away from the barb and is used to control the length of the rework needle extending outside the tube.

[0007] By adopting the above technical solution, the rework needle can slide within the body, the telescopic device can control the length of the rework needle extending outside the tube, and the barb at the end can be used when pulling back the end spring tongue, thus solving the problem of repairing the end spring tongue of the PIN removal tool, facilitating employee operations and reducing rework risks, and enabling the rework tool to have both PIN removal and spring tongue lifting functions.

[0008] Optionally, the telescopic device has a driving part, a locking part, and a rotating part. The driving part is mounted on the main body and is used to drive the rotating part to move. The rotating part is connected to the driving part and drives the locking part located in the cavity to rotate. The locking part is mounted on the rotating part and is used to abut or release the side surface of the repair needle.

[0009] By adopting the above technical solution, the rework tool can control the length of the rework needle extending outside the tube body through the telescopic device. The drive unit drives the rotating part to move, and the rotating part drives the locking part to rotate. The locking part abuts against or releases the side surface of the rework needle, which facilitates the control of the extension and retraction of the barb part. This realizes the function switching between end bullet tongue pull-back and conventional pin removal rework, which facilitates employee operation and reduces rework risks.

[0010] Optionally, the main body has a mounting hole, and the driving part includes a rubber button slidably arranged in the mounting hole and a tension spring disposed between the rubber button.

[0011] By adopting the above technical solution, the drive unit consisting of a rubber button and a tension spring installed in the mounting hole of the main body can be conveniently controlled to control the movement of the rotating part, thereby controlling the snap-fit ​​part to abut or release the repair pin.

[0012] Optionally, the rotating part includes a rotating shaft rotatably arranged in the cavity and a rod rotatably arranged on the rotating shaft. One end of the rod is connected to a rubber button, and the other end of the rod is connected to a snap-fit ​​part.

[0013] By adopting the above technical solution, force is applied to the rubber button, causing the rubber button to drive the rod to rotate around the axis of the rotating shaft. The rotation of the rod ensures the angle between the rod and the repair needle, realizing ground clamping or releasing.

[0014] Optionally, the locking part includes a convex structure formed on the end of the rod and a spring installed on the inner wall of the body. The end of the spring away from the inner wall of the body is connected to the rod, and the convex structure is locked onto both sides of the rework needle.

[0015] By adopting the above technical solution, the surfaces of the convex structure and the repair needle remain in contact under the force of the external spring.

[0016] Optionally, the repair needle located in the chamber has equidistant locking grooves on both sides, and the convex structure is engaged in the locking grooves.

[0017] By adopting the above technical solution, locking grooves are opened on both sides of the repair needle, allowing the convex structure to be locked in them. The locking grooves on the repair needle located inside the cavity and the convex structure maintain abutment, ensuring the extension length of the repair needle out of the tube body.

[0018] Optionally, the cross-section of the card slot is U-shaped, V-shaped, or rectangular.

[0019] By adopting the above technical solution, the extension and retraction of the rework pin can be controlled to realize routine pin removal rework and end spring tongue pull-back maintenance. It can also use a specific cross-sectional shape of the locking groove to ensure the stability of the telescopic device locking, which facilitates employee operation and reduces the risk of rework.

[0020] Optionally, the surface of the repair needle is formed with scale lines for marking length.

[0021] By adopting the above technical solution, the scale lines can help to accurately control the insertion length of the repair needle.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. It has the function of removing the pin and repairing the spring tongue at the back end, which solves the problem that traditional rework tools can only remove the pin, and avoids the connector from failing to lock the terminal because the spring tongue is not lifted, thus ensuring the normal function of the product; 2. The telescopic device can control the length of the repair needle extending outside the tube body and can flexibly adjust the position of the barb, making it convenient for terminal repair and spring tongue pull-back operations; 3. Enables integrated PIN removal and latch lifting operations, facilitating employee work and reducing safety risks and secondary damage to products caused by using unprofessional methods for rework.

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application discloses a novel rework tool.

[0031] Reference Figure 1 and Figure 2 As shown, the device includes a body 1, a rework needle 2, and a telescopic device 3. The body 1 has a chamber 4 for the rework needle 2 to slide through. A tube 5 is integrally formed on the body 1, and the tube 5 is connected to the chamber 4, allowing the rework needle 2 to move within the chamber 4 and the tube 5. A barb 6 is formed at the end of the rework needle 2, and a gap is formed between the barb 6 and the tube 5. The telescopic device 3 is installed at the end of the rework needle 2 away from the barb 6, and is used to control the length of the rework needle 2 extending outside the tube 5. The position of the rework needle 2 and the state of the barb 6 can be flexibly adjusted according to actual needs, achieving the effect of both regular pin removal rework and end spring tongue pull-back repair. Because the telescopic device 3 controls the length of the rework needle 2, the barb 6 can be extended or retracted, thus realizing different functions.

[0032] See Figure 2As shown, the body 1 is the main part of the rework tool. The shape of the body 1 can be cylindrical or cuboid, etc., for easy hand-held operation by the operator. The tube 5 on the body 1 is integrally molded with the body 1 to ensure structural stability. The inner diameter of the tube 5 is slightly larger than the outer diameter of the rework needle 2 to ensure that the rework needle 2 can slide smoothly within the tube 5. The tube 5 can also be made of the same material as the body 1 to ensure consistent overall performance. In some special cases, the body 1 can also be made of high-strength engineering plastics to reduce the weight of the tool and improve ease of operation.

[0033] See Figure 1 As shown, the rework needle 2 is a key component for performing rework tasks. Existing needles typically have a slender, needle-like structure, usually made of high-hardness alloy steel to ensure they are not easily deformed during rework. In this application, the barb 6 at the end of the rework needle 2 can be triangular or hook-shaped to easily hook the tip spring. The size of the barb 6 is determined based on the size of the terminal and the tip spring that need to be reworked. Scale lines 8 are formed on the surface of the rework needle 2 to indicate its length. The presence of scale lines 8 allows operators to accurately control the extension length of the rework needle 2, improving rework accuracy. In some applications where high precision is not required, the scale lines 8 can be omitted.

[0034] See Figure 3 and Figure 4 As shown, the telescopic device 3 is an important component for controlling the length of the rework needle 2. The telescopic device 3 has a driving part 31, a locking part 32, and a rotating part 33. The driving part 31 is mounted on the main body 1 and is used to drive the rotating part 33 to move. The rotating part 33 is connected to the driving part 31 and drives the locking part 32 located in the chamber 4 to rotate. The locking part 32 is mounted on the rotating part 33 and is used to abut or release the side surface of the rework needle 2.

[0035] See Figure 3 As shown, the drive unit 31 includes a rubber button 311 slidably arranged in a mounting hole and a tension spring 312 disposed between the rubber button 311. The main body 1 has a mounting hole, and the rubber button 311 can slide up and down in the mounting hole. The function of the tension spring 312 is to allow the rubber button 311 to spring back to its initial position after being pressed. The surface of the rubber button 311 has anti-slip textures to facilitate pulling or pressing operations by operators. The elastic coefficient of the tension spring 312 is selected according to actual needs to ensure the comfort and reliability of operation.

[0036] See Figure 3As shown, the rotating part 33 includes a rotating shaft 331 rotatably arranged in the chamber 4 and a rod 332 rotatably arranged on the rotating shaft 331. One end of the rod 332 is connected to the rubber button 311, and the other end of the rod 332 is connected to the locking part 32. When the rubber button 311 is pressed, the rod 332 rotates around the rotating shaft 331, thereby driving the locking part 32 to move. The rotating shaft 331 can be a cylindrical metal shaft, installed at a specific position in the chamber 4 to ensure the stability of the rotation.

[0037] See Figure 4 As shown, the locking part 32 includes a convex structure 321 formed on the end of the rod 332 and a spring 322 installed on the inner wall of the body 1. The end of the spring 322 away from the inner wall of the body 1 is connected to the rod 332. The convex structure 321 is locked onto both sides of the rework needle 2. Equally spaced locking grooves 7 are provided on both sides of the rework needle 2 located in the chamber 4, and the convex structure 321 is locked into the locking grooves 7. The function of the spring 322 is to ensure that the convex structure 321 always tends to abut against the rework needle 2, ensuring the stability of the locking. The cross-section of the locking groove 7 is U-shaped, V-shaped, or rectangular, etc. Different shapes of locking grooves 7 can be selected according to actual needs to adapt to different locking requirements. When the convex structure 321 is locked into the locking groove 7, the rework needle 2 is fixed in the corresponding position; when the driving part 31 drives the rotating part 33 to move, causing the convex structure 321 to disengage from the locking groove 7, the rework needle 2 can move freely.

[0038] The implementation principle of a novel rework tool according to this application embodiment is as follows: Through the coordinated action of the body 1, the rework needle 2, and the telescopic device 3, the body 1 provides the foundation for the support and operation of the entire tool. Under the control of the telescopic device 3, the rework needle 2 can flexibly adjust its position and state. The driving part 31, the rotating part 33, and the locking part 32 in the telescopic device 3 cooperate with each other. Through the operation of the driving part 31, the rotating part 33 is driven to move, thereby causing the locking part 32 to lock or release the rework needle 2, thereby controlling the length of the rework needle 2. The scale line 8 improves the accuracy of rework, thus solving the problem of the single function of traditional rework tools, facilitating employee operation, reducing the risks caused by rework, and improving maintenance efficiency and quality.
