Abstract
Description
Technical Field
[0001] This invention belongs to the field of disassembly fixture technology, and particularly relates to a disassembly fixture for disassembling relay terminals and its method of use. Background Technology
[0002] The connection between terminals and relays typically uses a snap-fit structure. During relay assembly, the terminals may sometimes be too loose or too tight, affecting the overall performance of the relay. Therefore, after the terminals and relay are manufactured, their connectivity needs to be tested. However, once connected to the relay, the terminals are held in place by the relay's snap-fit mechanism and cannot be easily removed.
[0003] Currently, most existing disassembly tools use a pin-type mechanism. While this method is simple and direct, it neglects the optimization of the disassembly tool and operation method, easily leading to damage to terminals or internal components. Specifically, during disassembly, the pin may scratch the terminals or damage other internal components of the relay, thus increasing unnecessary production costs and component waste. Therefore, the need to develop a disassembly fixture that simplifies the disassembly process and effectively protects the terminals and relays is increasingly urgent. Especially in mass production, this scratching phenomenon occurs frequently, consuming more time and resources for quality inspection and repair.
[0004] To address the aforementioned issues, a novel disassembly fixture has been developed. This fixture aims to simplify the disassembly process while effectively protecting terminals and relays from damage. Traditional pin-operated methods not only scratch terminals and relays but also increase operational complexity and impact production efficiency. The new fixture, through its ingenious design, safely removes terminals from relays, preventing damage to components, ensuring disassembly quality, improving efficiency, and reducing production costs, thereby significantly enhancing overall product quality and market competitiveness. Summary of the Invention
[0005] The purpose of this invention is to provide a disassembly fixture for disassembling relay terminals, aiming to solve the technical problem that in the prior art, the connection between terminals and relays is generally a snap-fit connection, and after the terminals are tested, the terminals cannot be directly removed from the relay. The traditional ejector pin method of removal can easily cause damage to the internal parts of the terminals or relays.
[0006] To achieve the above objectives, this invention provides a disassembly fixture for disassembling relay terminals, comprising a handheld component and a disassembly component. One end of the handheld component is connected to the disassembly component, which is used to press the latching member of the relay. The handheld component is for use by an operator. The disassembly component has a guide portion and a pressing portion at its end away from the handheld component. The guide portion guides the disassembly component into the relay terminal, and the pressing portion guides the pressing portion to abut against the latching member of the relay. The pressing portion cooperates with the latching member of the relay, and the pressing portion is used to press the latching member of the relay to release the terminal inside the relay.
[0007] Furthermore, the handheld component includes a fixed post and a movable post. One end of the fixed post is hinged to one end of the movable post, and the movable post rotates about its hinge point with the fixed post. A guide portion is connected to the end of the fixed post away from its hinge point, and a pressing portion is connected to the end of the movable post away from its hinge point. When the movable post is driven to rotate, the guide portion and the pressing portion move closer to or further away from each other.
[0008] Furthermore, it also includes a limiting ring, which is sleeved on the end of the fixed column and the movable column away from their hinge point and is fixedly connected to the fixed column. The movable column rotates within the limiting ring about its hinge point with the fixed column. An elastic element is also provided between the fixed column and the movable column. One end of the elastic element abuts against the fixed column, and the other end of the elastic element abuts against the movable column. The elastic element is used to drive the movable column to abut against the limiting ring.
[0009] Furthermore, the guide portion extends outward at the end away from the fixed post and is provided with an insertion block, with a first guide groove and a second guide groove respectively on both sides of the insertion block.
[0010] Furthermore, the pressing part extends outward at the end away from the moving column and has a connecting groove corresponding to the latching part of the relay.
[0011] Furthermore, the guide part is detachably mounted on the fixed column, and the pressing part is detachably mounted on the movable column.
[0012] Furthermore, the outer surface of the handheld component is patterned.
[0013] This invention also provides a method for using a disassembly fixture for removing relay terminals, comprising the following steps: Step 1: The operator holds a handheld component and inserts the disassembly component along the gap of the relay. Under the action of the guide part, the pressing part contacts the latching member that holds the terminal on the relay. Step 2: Gradually press down on the handheld component. Under the action of the handheld component, the pressing part pushes open the latching member, and the terminal is no longer limited by the latching member. Step 3: Pull the terminal outward to complete the removal of the terminal.
[0014] The disassembly fixture for disassembling relay terminals provided in this invention provides at least one of the following technical effects: The operator holds a handheld component and inserts the disassembly component along the gap in the relay. Under the action of the guide portion, the pressing portion contacts the latching member that holds the terminal on the relay. The handheld component is gradually pressed down, and under its action, the pressing portion pushes open the latching member, thus removing the terminal from its position. The terminal is then pulled outwards, completing the disassembly. During this process, the guiding part allows the pressing part to smoothly abut against the latching component. Compared to using an ejector pin, this avoids scratching the terminal and the inside of the relay. After the pressing part and the latching component abut, the pressing part drives the latching component to elastically deform, causing the latching component to no longer restrict the terminal and allowing the terminal to be easily removed. Compared to the ejector pin method of ejecting the terminal, this avoids the ejector pin directly damaging the latching component and causing it to break. It also avoids deformation of the terminal during the ejector pin abutting process, allowing the terminal to be safely removed from the relay without damaging the parts and ensuring the quality of disassembly. The guiding part improves efficiency and reduces production costs, thereby significantly improving the overall quality and market competitiveness of the product. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of the present invention, "a plurality of" means two or more, unless otherwise explicitly specified.
[0024] In the embodiments of the present invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.
[0025] In one embodiment of the present invention, reference is made to... Figures 1-4As shown, a disassembly fixture for disassembling relay terminals is provided, including a handheld component 10 and a disassembly component 20. One end of the handheld component 10 is connected to the disassembly component 20. The disassembly component 20 is used to press the latching member 30 of the relay, and the handheld component 10 is for the operator to hold. The disassembly component 20 has a guide portion 21 and a pressing portion 22 at the end away from the handheld component 10. The guide portion 21 guides the disassembly component 20 into the relay terminal and guides the pressing portion 22 to abut against the latching member 30 of the relay. The pressing portion 22 cooperates with the latching member 30 of the relay, and the pressing portion 22 is used to press the latching member 30 of the relay to release the terminal inside the relay. In this embodiment, the operator holds the handheld component 10 and then inserts the disassembly component 20 along the gap of the relay. Under the action of the guide portion 21, the pressing portion 22 contacts the latching member 30 of the relay that holds the terminal. Gradually press down on the handheld component 10. Under the action of the handheld component 10, the pressing part 22 pushes open the latching member 30, so that the terminal is no longer limited by the latching member 30. Pull the terminal outward to complete the terminal removal. During this process, due to the action of the guide part 21, the pressing part 22 can smoothly abut against the latching member 30. Compared with using a ejector pin to push out the material, this can avoid scratching the terminal and the inside of the relay. After the pressing part 22 and the latching member abut against each other, pressing the pressing part 22 drives the latching member to elastically deform, so that the latching member 30 no longer limits the terminal, allowing the terminal to be removed smoothly. Compared with the ejector pin method of pushing out the terminal, this can avoid the ejector pin directly damaging the latching member 30 and causing the latching member 30 to break. At the same time, it can also avoid the terminal being deformed during the process of the ejector pin abutting against the terminal. The terminal can be safely removed from the relay, avoiding damage to the parts and ensuring the quality of removal. Under the guidance of the guide part 21, efficiency is improved, production costs are reduced, and the overall quality and market competitiveness of the product are significantly improved.
[0026] Specifically, refer to Figures 1-3 As shown, the handheld assembly 10 includes a fixed post 11 and a movable post 12. One end of the fixed post 11 is hinged to one end of the movable post 12, and the movable post 12 rotates about its hinge point with the fixed post 11. A guide portion 21 is connected to the end of the fixed post 11 away from its hinge point, and a pressing portion 22 is connected to the end of the movable post 12 away from its hinge point. When the movable post 12 is driven to rotate, the guide portion 21 and the pressing portion 22 move closer to or further away from each other. In this embodiment, when the guide portion 21 guides the pressing portion 22 to abut against the latching member 30, and the operator drives the movable post 12 to move closer to the fixed post 11 about its hinge point with the fixed post 11, the pressing portion 22 presses against the latching member 30. At the same time, the fixed post 11 and the movable post 12 cooperate to clamp the relay, allowing for operation with one hand. The other hand can then pull out the terminal, making the operation simpler and faster.
[0027] Specifically, refer to Figures 1-3As shown, it also includes a limiting ring 13, which is sleeved on the end of the fixed column 11 and the movable column 12 away from their hinge point and is fixedly connected to the fixed column 11. The movable column 12 rotates within the limiting ring 13 about its hinge point with the fixed column 11. An elastic element 14 is also provided between the fixed column 11 and the movable column 12. One end of the elastic element 14 abuts against the fixed column 11, and the other end of the elastic element 14 abuts against the movable column 12. The elastic element 14 is used to drive the movable column 12 to abut against the limiting ring 13. In this embodiment, the limiting ring 13 is used to limit the rotation angle of the moving column 12. The elastic element 14 allows the moving column 12 to be connected to both ends of the limiting ring 13 when it is not subjected to external force. At this time, the pressing part 22 and the guide part 21 correspond to the positions in the relay. When the pressing part 22 abuts against the buckle 30, it drives the elastic element 14 to compress. The fixed column 11 and the moving column 12 move closer to each other to move the buckle 30. The setting of the limiting ring 13 and the elastic element 14 keeps the distance between the guide part 21 and the abutting part entering the relay and the distance between the position used for positioning in the relay and the position of the buckle 30 a certain distance, so that the positioning is more accurate.
[0028] More specifically, see reference Figures 1-3 As shown, the fixed column 11 and the movable column 12 are made of aluminum alloy, and the fixed column 11 and the movable column 12 have hollow parts inside to reduce weight and facilitate operation by the operator.
[0029] Specifically, refer to Figures 1-3 As shown, the guide portion 21 extends outward from the end away from the fixing post 11 and is provided with an insertion block 23. The two sides of the insertion block 23 are respectively provided with a first guide groove 24 and a second guide groove 25. In this embodiment, the insertion block 23 is inserted into the relay, which can be considered as the insertion block 23 being connected to the relay. At this time, the pressing portion 22 is also connected to the latching member 30. Driving the fixing post 11 and the moving post 12 closer together allows the relay to be clamped, while the latching member 30 also undergoes elastic deformation, facilitating one-handed removal of the terminal. The first guide groove 24 and the second guide groove 25 serve to guide the insertion block 23 into the relay.
[0030] Specifically, refer to Figures 1-3 As shown, the pressing part 22 extends outward at the end away from the moving post 12 and has a connecting groove 26 corresponding to the latching member 30 of the relay. In this embodiment, the shape of the connecting groove 26 matches that of the latching member 30, so that the latching member 30 can be housed in the connecting groove 26 for easy pressing of the latching member 30.
[0031] Specifically, refer to Figures 1-3As shown, the guide portion 21 is detachably mounted on the fixed post 11, and the pressing portion 22 is detachably mounted on the movable post 12. In this embodiment, by replacing different guide portions 21 and pressing portions 22 according to different internal structures of the terminal connector, the disassembly fixture for disassembling relay terminals provided by the present invention can be applied to various electrical components connected to the terminals.
[0032] Specifically, refer to Figures 1-4 As shown, the outer surface of the handheld component 10 is patterned. In this embodiment, the pattern is used to increase friction, making it easier for workers to operate.
[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
