Description

Technical Field

[0001] The present invention belongs to the technical field of disassembly jigs, and particularly relates to a disassembly jig for disassembling relay terminals and a method for using the same. Background Art

[0002] The connection between the terminal and the relay usually adopts a snap structure. During the assembly of the relay terminal, sometimes the connection may be too loose or too tight, which will affect the overall performance of the relay. Therefore, after the production of the terminal and the relay is completed, it is necessary to detect their connectivity. However, after the terminal is connected to the relay, it will be stuck by the snap member of the relay and cannot be directly taken out.

[0003] Currently, most of the existing disassembly tools adopt the thimble method. Although this method is simple and direct, it ignores the optimization of the disassembly tool and the operation method, and is likely to cause damage to the terminal or internal components. That is, during the disassembly process, the thimble may scratch the terminal or damage other components inside the relay, thereby increasing unnecessary production costs and part losses. Therefore, the need to develop a disassembly jig that can simplify the disassembly process and effectively protect the terminal and the relay is becoming increasingly urgent. Especially in mass production, this scratching phenomenon will occur frequently, occupying more time and resources for quality inspection and repair.

[0004] To solve the above problems, a new type of disassembly jig has emerged. The purpose of this jig is to simplify the disassembly process while effectively protecting the terminal and the relay from damage. The traditional thimble method not only scratches the terminal and the relay, but also increases the operational complexity during the production process, affecting the production efficiency. The new jig can safely disassemble the terminal from the relay through a clever design, avoiding damage to the parts, ensuring the disassembly quality, improving the efficiency, reducing the production cost, and thus significantly enhancing the overall quality and market competitiveness of the product. Summary of the Invention

[0005] The purpose of the present invention is to provide a disassembly jig for disassembling relay terminals, aiming to solve the technical problem in the prior art that the connection between the terminal and the relay generally adopts a snap connection, and after the terminal is tested, the terminal cannot be directly taken out from the relay, and the traditional thimble method is likely to cause damage to the terminal or the inside of the relay.

[0006] To achieve the above object, an extraction jig for extracting relay terminals provided by an embodiment of the present invention includes a hand-held assembly and an extraction assembly. One end of the hand-held assembly is connected to the extraction assembly. The extraction assembly is used to press a snap member of the relay, and the hand-held assembly is used for an operator to hold. The extraction assembly is provided with a guiding portion and a pressing portion at one end away from the hand-held assembly. The guiding portion is used to guide the extraction assembly to extend into the relay terminal and to guide the pressing portion to abut against the snap member of the relay. The pressing portion cooperates with the snap member of the relay, and the pressing portion is used to press the snap member of the relay to release the terminal in the relay.

[0007] Further, the hand-held assembly includes a fixed column and a movable column. One end of the fixed column is hinged to one end of the movable column, and the movable column rotates around its hinge point with the fixed column. The guiding portion is connected to the end of the fixed column away from its hinge point, and the pressing portion is connected to the end of the movable column away from its hinge point. When the movable column is driven to rotate, the guiding portion and the pressing portion approach or move away from each other.

[0008] Further, it further includes a limiting ring. The limiting ring is sleeved on the ends of the fixed column and the movable column away from their hinge points and is fixedly connected to the fixed column. The movable column rotates around its hinge point with the fixed column inside the limiting ring. An elastic member is further provided between the fixed column and the movable column. One end of the elastic member abuts against the fixed column, and the other end of the elastic member abuts against the movable column. The elastic member is used to drive the movable column to abut against the limiting ring.

[0009] Further, the guiding portion extends outward at one end away from the fixed column to be provided with an insertion block, and a first guiding groove and a second guiding groove are respectively provided on both sides of the insertion block.

[0010] Further, the pressing portion extends outward at one end away from the movable column to be provided with a connection groove corresponding to the snap member of the relay.

[0011] Further, the guiding portion is detachably mounted on the fixed column, and the pressing portion is detachably mounted on the movable column.

[0012] Further, the outer surface of the hand-held assembly is provided with patterns.

[0013] The present invention also provides a method for using an extraction jig for extracting relay terminals, including the following steps: Step 1: An operator holds the hand-held assembly, and then inserts the extraction assembly along the gap of the relay. Under the action of the guiding portion, the pressing portion contacts the snap member that clamps the terminal on the relay. Step 2: Gradually press down the hand-held assembly. Under the action of the hand-held assembly, the pressing portion pushes open the snap member, and then the terminal is no longer limited by the snap member. Step 3: Pull out the terminal outward to complete the extraction of the terminal.

[0014] One or more of the above technical solutions in a disassembly jig for disassembling relay terminals provided by an embodiment of the present invention at least have one of the following technical effects: The operator holds the handheld component, and then inserts the disassembly component along the gap of the relay. Under the action of the guiding portion, the pressing portion contacts the buckle member that clamps the terminal on the relay. Gradually press down the handheld component. Under the action of the handheld component, the pressing portion pushes open the buckle member, and then the terminal is no longer limited by the buckle member. Pull out the terminal outward to complete the disassembly of the terminal. During this process, due to the action of the guiding portion, the pressing portion can smoothly abut against the buckle member. Compared with using a thimble for ejecting materials, it can avoid scratching the terminal and the interior of the relay. When the pressing portion abuts against the buckle, press the pressing portion to drive the buckle to elastically deform, so that the buckle member no longer limits the terminal, and the terminal can be smoothly taken out. Compared with the method of ejecting the terminal with a thimble, it can avoid directly damaging the buckle member by the thimble and causing the buckle member to break, and at the same time can also avoid causing deformation of the terminal during the process of the thimble abutting against the terminal. The terminal can be safely disassembled from the relay, avoiding damage to the parts, ensuring the disassembly quality, improving the efficiency under the guiding action of the guiding portion, reducing the production cost, and thus significantly improving the overall quality and market competitiveness of the product.

[0025] In one embodiment of the present invention, refer to Figures 1 to 4As shown in the figure, a disassembly jig for disassembling relay terminals is provided, which includes 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 buckle 30 of the relay, and the handheld component 10 is used for an operator to hold. The disassembly component 20 is provided with a guiding part 21 and a pressing part 22 at one end far from the handheld component 10. The guiding part 21 is used to guide the disassembly component 20 to extend into the relay terminal and to guide the pressing part 22 to abut against the buckle 30 of the relay. The pressing part 22 cooperates with the buckle 30 of the relay, and the pressing part 22 is used to press the buckle 30 of the relay to release the terminal in 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 guiding part 21, the pressing part 22 contacts the buckle 30 that clamps the terminal on the relay. Gradually press down the handheld component 10. Under the action of the handheld component 10, the pressing part 22 pushes open the buckle 30, and then the terminal is no longer limited by the buckle 30. Pull out the terminal outward to complete the disassembly of the terminal. During this process, due to the action of the guiding part 21, the pressing part 22 can smoothly abut against the buckle 30. Compared with using a thimble for ejecting materials, it can avoid scratching the terminal and the inside of the relay. When the pressing part 22 abuts against the buckle, press the pressing part 22 to drive the buckle to deform elastically, so that the buckle 30 no longer limits the terminal, and the terminal can be taken out smoothly. Compared with the method of using a thimble to eject the terminal, it can avoid the thimble directly damaging the buckle 30 and causing the buckle 30 to break, and at the same time can also avoid the terminal deforming during the process of the thimble abutting against the terminal. The terminal can be safely disassembled from the relay, avoiding damage to the parts, ensuring the disassembly quality, improving the efficiency under the guiding action of the guiding part 21, reducing the production cost, and thus significantly improving the overall quality and market competitiveness of the product.

[0026] Specifically, referring to Figures 1 to 3 As shown in the figure, the handheld component 10 includes a fixed column 11 and a moving column 12. One end of the fixed column 11 is hinged to one end of the moving column 12, and the moving column 12 rotates around its hinge point with the fixed column 11. The guiding part 21 is connected to the end of the fixed column 11 far from its hinge point, and the pressing part 22 is connected to the end of the moving column 12 far from its hinge point. When the moving column 12 is driven to rotate, the guiding part 21 and the pressing part 22 approach or move away from each other. In this embodiment, when the guiding part 21 guides the pressing part 22 to abut against the buckle 30, when the operator drives the moving column 12 to approach the fixed column 11 around its hinge point with the fixed column 11, the pressing part 22 presses the buckle 30, and at the same time, the fixed column 11 and the moving column 12 cooperate to clamp the relay, and the operation can be carried out with one hand. Then, the other hand pulls out the terminal, and the operation is simpler and faster.

[0027] Specifically, referring to Figures 1 to 3As shown in the figure, it further includes a limiting ring 13. The limiting ring 13 is sleeved on the ends of the fixed column 11 and the moving column 12 that are away from their hinge points, and is fixedly connected to the fixed column 11. The moving column 12 rotates within the limiting ring 13 around its hinge point with the fixed column 11. An elastic member 14 is further provided between the fixed column 11 and the moving column 12. One end of the elastic member 14 abuts against the fixed column 11, and the other end of the elastic member 14 abuts against the moving column 12. The elastic member 14 is used to drive the moving 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. When the elastic member 14 is under no external force, the moving column 12 and the fixed column 11 are respectively connected to both ends of the limiting ring 13. At this time, the pressing portion 22 and the guiding portion 21 correspond to the positions in the relay. When the pressing portion 22 abuts against the buckle member 30, the elastic member 14 is driven to compress, and the fixed column 11 and the moving column 12 approach each other to toggle the buckle member 30. Through the settings of the limiting ring 13 and the elastic member 14, the distance between the guiding portion 21 and the abutting portion entering the relay is kept constant with the distance between the position for positioning in the relay and the position of the buckle member 30, making the positioning more accurate.

[0028] More specifically, referring to Figures 1 to 3 As shown in the figure, the fixed column 11 and the moving column 12 are made of aluminum alloy, and hollow portions are provided inside the fixed column 11 and the moving column 12 to reduce weight and facilitate operation by the operator.

[0029] Specifically, referring to Figures 1 to 3 As shown in the figure, an insertion block 23 extends outward at the end of the guiding portion 21 away from the fixed column 11. First guiding grooves 24 and second guiding grooves 25 are respectively provided on both sides of the insertion block 23. In this embodiment, by inserting the insertion block 23 into the relay, it can be regarded as the insertion block 23 being connected to the relay. At this time, the pressing portion 22 is also connected to the buckle member 30. When the fixed column 11 and the moving column 12 are driven to approach each other, the relay can be clamped and the buckle member 30 also undergoes elastic deformation, facilitating the single-handed operation to remove the terminal. The functions of the first guiding groove 24 and the second guiding groove 25 are to guide the insertion block 23 into the relay.

[0030] Specifically, referring to Figures 1 to 3 As shown in the figure, a connection groove 26 corresponding to the buckle member 30 of the relay extends outward at the end of the pressing portion 22 away from the moving column 12. In this embodiment, the connection groove 26 matches the shape of the buckle member 30, so that the buckle member 30 is received in the connection groove 26 to facilitate pressing the buckle member 30.

[0031] Specifically, referring to Figures 1 to 3As shown, the guiding part 21 is detachably installed on the fixed column 11, and the pressing part 22 is detachably installed on the moving column 12. In this embodiment, different guiding parts 21 and pressing parts 22 are replaced according to different internal structures of the terminal connector, so that a disassembly jig for disassembling relay terminals provided by the present invention can be applied to various electrical parts connected to the terminals.

[0032] Specifically, referring to Figures 1 to 4 As shown, the outer surface of the handheld assembly 10 is provided with patterns. In this embodiment, the patterns are used to increase the friction force and facilitate the operation of workers.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
