Abstract
Description
Technical Field
[0001] This utility model is a 90° torsion terminal with rubber coating, belonging to the electrical field. Background Technology
[0002] As electronic devices continue to evolve towards miniaturization and thinner designs, their internal space becomes increasingly compact. In this context, optimizing circuit layout has become a critical challenge. The 90° twist terminal block, with its unique twisting structure, offers an effective solution to this problem. It allows wires to smoothly achieve a 90° turn within extremely confined spaces, thereby significantly optimizing the internal circuit layout of electronic devices and achieving more efficient circuit connections within limited space.
[0003] In the design of the 90° torsion terminal encapsulation component, the connecting terminal is equipped with claws made of thermoplastic elastomer. It is worth noting that these claws and the encapsulated material in the 90° torsion terminal encapsulation component are manufactured using a one-piece molding process. While this design enhances the overall structural stability to some extent, it also has certain drawbacks. If the claws break or are damaged due to external forces such as compression, it will directly affect the normal use of the 90° torsion terminal encapsulation component, potentially adversely impacting the circuit connection stability and functionality of the entire electronic device. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a 90° twisted terminal encapsulated component to solve the problems mentioned in the background section. This invention enables the claw to be connected to the adhesive body in an assembled manner, allowing the claw to be replaced individually when it is damaged.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a 90° twisted terminal encapsulation component, comprising an adhesive body, four support sleeves mounted on one side of the adhesive body, a connecting terminal inserted into the support sleeves, one end of the connecting terminal extending into the adhesive body, a 90° twisted portion integrally formed at the end of the connecting terminal within the adhesive body, a plug-in terminal integrally formed at the end of the twisted portion away from the connecting terminal, the plug-in terminal extending away from the twisted portion to the outside of the adhesive body, a plug-in sleeve fitted onto the connecting terminal, one end of the plug-in sleeve contacting the support sleeve, claws mounted on two parallel sides of the plug-in sleeve, a groove recessed on one side of the support sleeve, a connecting plate inserted into the groove, one end of the connecting plate connected and fixedly connected to the plug-in sleeve, an ear plate mounted on the end of the connecting plate away from the plug-in sleeve, the ear plate being connected to the adhesive body via a connector.
[0006] Furthermore, the connector includes a frame, one side of the ear plate is provided with a frame, the four support sleeves are respectively set at the four corners inside the frame, one side of the ear plate is provided with a positioning hole, one side of the frame is provided with four positioning heads, the positioning heads are inserted into the positioning holes, and a horizontal plate is installed in the middle of the frame that contacts one side of the colloid, the horizontal plate is connected to the colloid by screws.
[0007] Furthermore, two protrusions are installed on one side of the frame mounting positioning head, and the area of the colloid opposite the frame is recessed to form two positioning grooves that cooperate with the protrusions, and the protrusions are inserted into the positioning grooves.
[0008] Furthermore, a slot is provided on one side of the colloid, and a plug is inserted into the slot. A round hole is provided in the middle of one side of the horizontal plate. A through hole is provided in the area of the colloid covered by the horizontal plate. The through hole communicates with the slot. A screw hole is provided on one side of the plug, which is aligned with the through hole. One end of the screw passes through the channel formed by the round hole and the through hole and is threaded into the screw hole.
[0009] Furthermore, a detachable push rod is installed on one side of the insert block, the end of the push rod away from the insert block extends to the outside of the slot, a limiting plate is sleeved on the push rod and fixed to the push rod, and a handle is installed on the end of the push rod away from the insert block.
[0010] Furthermore, the outer surface of the end of the push rod away from the handle is machined with external threads, and a threaded blind hole is opened on one side of the insert block. The end of the push rod with the external threads is threaded into the threaded blind hole.
[0011] Furthermore, the slot has a triangular cross-section, and the insert has a triangular cross-section.
[0012] The beneficial effects of this utility model are:
[0013] 1. Breaking through the limitations of traditional one-piece molding of the claw and the PVC body, this design adopts an assembly method for connection. The claw is mounted on the connector sleeve, which is connected to the PVC body via a connecting plate, ear plate, and frame. When the claw is damaged due to compression, etc., it is not necessary to replace the entire PVC body; only the connector sleeve needs to be disassembled to replace the claw individually. This significantly reduces maintenance costs, improves efficiency, and ensures the continuous stability of electronic equipment circuit connections.
[0014] 2. Insert the connecting plate on the plug sleeve into the corresponding slot on the support sleeve, then use the frame to press the four ear plates, and insert the positioning head into the positioning hole, so that the relative position of the frame and the connecting plate remains unchanged. Use screws to connect the horizontal plate and the colloid to complete the assembly of the frame and the colloid. This allows the relative position of multiple plug sleeves and colloids to be restricted with one screw, reducing the number of screws used and improving assembly efficiency.
[0015] 3. Machining the screw holes that mate with the screws onto the insert block, and then inserting the insert block into the slot to assemble the insert block and the colloid. When the screw holes are damaged, the insert block can be replaced separately. Compared to machining the screw holes onto the colloid, this avoids damage to the colloid due to stripped threads, which could affect the installation of the frame. Attached Figure Description

Detailed Implementation
[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] Please see Figures 1-3This utility model provides a technical solution: a 90° twisted terminal encapsulated part, including a colloid 1. Four support sleeves 8 are installed on one side of the colloid 1, which is made of thermoplastic elastomer. A connecting terminal 7 is inserted into the support sleeve 8. One end of the connecting terminal 7 extends into the colloid 1. A 90° twisted portion 15 is integrally formed at the end of the connecting terminal 7 away from the connecting terminal 7. A plug-in terminal 12 is integrally formed at the end of the twisted portion 15 away from the connecting terminal 7. The plug-in terminal 12 extends to the outside of the colloid 1 away from the twisted portion 15. By performing a second 90° twisting process on the tail of the stamped terminal and then encapsulating it for fixation, the electrical clearance of the product is increased.
[0025] See Figures 1-4 A plug-in sleeve 6 is fitted onto the connecting terminal 7. One end of the plug-in sleeve 6 contacts the support sleeve 8. Claws 5 are installed on both parallel sides of the plug-in sleeve 6. A groove 13 is recessed on one side of the support sleeve 8, and a connecting plate 4 is inserted into the groove 13. One end of the connecting plate 4 is connected and fixed to the plug-in sleeve 6, and an ear plate 23 is installed on the end of the connecting plate 4 away from the plug-in sleeve 6. The claws 5 are installed on the plug-in sleeve 6, and the plug-in sleeve 6 is connected to the adhesive body 1 via the connecting plate 4, ear plate 23, and frame 3. This assembly structure brings great convenience. When the claws 5 are damaged due to external pressure, maintenance personnel do not need to replace the entire coated part; they only need to disassemble the plug-in sleeve 6 connected to the claws 5 to easily replace the claws individually. This improvement not only significantly reduces maintenance costs and unnecessary resource waste but also greatly improves efficiency. Even if the pawl 5 malfunctions during the operation of electronic equipment, it can be repaired quickly, ensuring a continuous and stable circuit connection and preventing circuit connection interruptions caused by damage to the pawl 5, thus guaranteeing the normal operation of electronic equipment.
[0026] See Figures 1-4The ear plate 23 has a frame 3 on one side, and four support sleeves 8 are respectively set at the four corners of the frame 3. The ear plate 23 has a positioning hole 22 on one side, and four positioning heads 16 are installed on one side of the frame 3. The positioning heads 16 are inserted into the positioning holes 22. A horizontal plate 20 is installed in the middle of the frame 3, which is in contact with one side of the colloid 1. The horizontal plate 20 is connected to the colloid 1 by screws 21. Two protrusions 2 are installed on the side of the frame 3 where the positioning heads 16 are installed. The area of the colloid 1 opposite to the frame 3 is recessed to form two positioning grooves 14 that cooperate with the protrusions 2. The protrusions 2 are inserted into the positioning grooves 14. The positioning heads 16 cooperate with the positioning holes 22 of the ear plate 23, and the protrusions 2 fit with the positioning grooves 14 of the colloid 1. Multiple positioning structures work together to ensure the accuracy of the installation position of each component and effectively prevent the connection terminal 7, plug sleeve 6, etc. from shifting or shaking during use. The frame 3 with positioning heads 16 is placed in a suitable position so that it applies uniform pressure to the four ear plates 23. During the pressing process, the positioning head 16 on the frame 3 is precisely aligned with and inserted into the positioning hole 22 on the ear plate 23. This securely locks the relative positions of the frame 3 and the connecting plate 4, preventing easy movement. Finally, a single screw 21 connects the horizontal plate 20 to the colloid 1. The key here is that this screw 21 acts as a "one-for-many" unit, successfully limiting the relative positions of multiple insert sleeves 6 and the colloid 1. Compared to the previous method requiring multiple screws 21 for fixation, this innovative design significantly reduces the number of screws 21 used. This not only reduces the operational complexity caused by excessive screws 21 during assembly but also significantly improves overall assembly efficiency, making product production and assembly more efficient and convenient.
[0027] See Figure 1 , Figure 2 , Figure 4 and Figure 5One side of the colloid 1 has a slot 9 with a triangular cross-section, into which a triangular insert 17 is inserted. A circular hole is located in the center of one side of the horizontal plate 20. A through hole is located in the area of the colloid 1 covered by the horizontal plate 20, communicating with the slot 9. One side of the insert 17 has a screw hole 19 aligned with the through hole. One end of a screw 21 passes through the channel formed by the circular hole and the through hole and is threaded into the screw hole 19. The screw hole 19, which mates with the screw 21, is located on the insert 17, rather than on the colloid 1 in the traditional way. During assembly, the insert 17 is inserted into the slot 9 of the colloid 1, thus completing the connection between the insert 17 and the colloid 1. This design has significant advantages; if the screw hole 19 is damaged due to external force, such as stripping, only the insert 17 needs to be replaced to solve the problem. If the screw hole 19 is machined directly onto the colloid 1, the colloid 1 itself will be damaged if the screw hole 19 strips, which will affect the installation stability of the frame 3 and the normal use of the entire coated part. Now, by setting the screw hole 19 on the insert block 17, the colloid 1 is effectively prevented from being damaged due to screw hole problems, which greatly improves the durability and maintainability of the product.
[0028] See Figure 1 , Figure 2 , Figure 4 and Figure 5 One side of the insert block 17 is equipped with a detachable push rod 11. The outer surface of the end of the push rod 11 away from the handle is machined with external threads. One side of the insert block 17 has a threaded blind hole 18, so that the threaded end of the push rod 11 is threaded into the threaded blind hole 18, facilitating the assembly and disassembly of the push rod 11 and the insert block 17. The end of the push rod 11 away from the insert block 17 extends to the outside of the slot 9. A limiting plate 10 is fitted on the push rod 11 and fixed to it. A handle is installed on the end of the push rod 11 away from the insert block 17. During assembly, the push rod 11 is first connected to the insert block 17. After connection, with the help of the push rod 11, the insert block 17 is smoothly inserted into the slot 9 of the colloid 1. As the insert block 17 is inserted, the push rod 11 is pushed until the limiting plate 10 is tightly fitted to one side of the colloid 1. During this process, thanks to the precise positioning of the limiting plate 10, the screw hole 19 on the insert block 17 can be accurately aligned with the through hole on the colloid 1. This series of operations is completed in one go, greatly simplifying the assembly process, reducing the steps of repeated debugging and alignment, and effectively improving the overall assembly efficiency.
