Description

Technical Field

[0001] This utility model relates to the technical field of terminal wire connection components, specifically a terminal wire connection component. Background Technology

[0002] In the field of electronic component assembly, the connection between terminals and terminal wires is a basic and critical process. The quality of the connection directly affects the overall performance and stability of electronic equipment. At present, the industry generally uses terminal crimping machines to crimp and fix terminals and terminal wires. However, in the process of feeding the terminal wires into the terminal crimping machine's feed port, most of the work still relies on manual operation. Specifically, the operator needs to hold the terminal wire, align it with the feed port of the terminal crimping machine, and feed it into the equipment to achieve the fixed installation of the terminal on the terminal wire. However, this manual feeding method has many insurmountable drawbacks: due to the limited precision of the operator's hand movements, and the tendency to experience fatigue and unstable operating force during long-term operation, the feeding distance of the terminal wire into the terminal crimping machine is difficult to maintain consistently each time. This difference in feeding distance directly causes deviations in the fixed position of the terminal on the terminal wire. This positional deviation not only affects the assembly accuracy of electronic components, making subsequent assembly processes difficult to carry out smoothly, but may also reduce the reliability of the connection between the terminal and the terminal wire, causing problems such as poor contact and unstable signal transmission during the use of electronic equipment. In severe cases, it may even lead to equipment failure and economic losses. Utility Model Content

The terminal crimping machine is placed at the top of the workbench. A housing is provided at the top of the workbench in front of the terminal crimping machine's feed inlet. A cavity is formed inside the housing, and a feeding plate is rotatably connected to both sides of the cavity via shafts. An arc-shaped limiting groove is formed inside the feeding plate, and a limiting block is slidably connected inside the limiting groove. The bottom end of the limiting block is connected to the inner wall of the housing. A transmission assembly is provided at the top of the feeding plate. A discharge groove is formed at the top of the housing, and a storage box is fixed above the discharge groove. A discharge roller is rotatably connected to the bottom of the storage box. A drive assembly for discharging is connected to both sides of the discharge roller through the storage box via rotating rods.

[0005] Preferably, the front and rear sides of the outer casing are symmetrically provided with through slots, and the positions of the through slots correspond to the feed port of the terminal block machine.

[0006] Preferably, a material support plate is fixed at the center of the interior of the outer shell. The material support plate is located between the feeding plates and corresponds to the through groove of the outer shell for feeding and picking up materials.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The outer casing not only effectively protects the internal transmission components such as the feeding plate and the support plate, preventing dust and debris from contaminating the components and affecting the transmission accuracy, but also prevents operators from directly contacting the moving parts, significantly reducing the risk of safety accidents and improving the safety of equipment use. The feeding plate slides with the limiting block through the arc-shaped limiting groove. The cylindrical structure of the limiting block and the arc-shaped limiting groove form a precise guide, ensuring that the feeding plate can only swing along the set arc trajectory, effectively controlling the distance accuracy of pushing the connecting line material, and avoiding terminal implantation deviation caused by feeding offset. In the transmission assembly, the limiting slot block guides and limits the transmission rod, ensuring that the transmission rod only performs linear reciprocating motion along the axial direction. Then, the linear motion is precisely converted into the swing motion of the feeding plate by the pull rope, thereby achieving the stability and accuracy of power transmission and improving the reliability of the feeding action. The inner wall of the storage box is designed with an arc shape to facilitate the smooth entry of materials into the feeding roller and avoid material accumulation and blockage; the strip grooves on both sides of the feeding roller can accurately accommodate a single wire, and the single wire can be quantitatively fed by rotation, which effectively prevents the problems of material jamming and feeding disorder caused by multiple materials being fed at the same time; As a manually operated component, the pull plate has a simple structure and is easy to hold. Operators can provide power to the transmission rod by pushing and pulling the pull plate to realize the feeding action. The operation method is intuitive and convenient, reducing the threshold of manual operation. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 This utility model provides a technical solution for a terminal wire connection assembly: a terminal wire connection assembly includes a workbench 1 and a terminal crimping machine 2. The terminal crimping machine 2 is placed on the top of the workbench 1, providing a stable and flat mounting base for core components such as the terminal crimping machine 2 and the housing 3. The housing 3 is located on the top of the workbench 1 in front of the inlet of the terminal crimping machine 2, protecting the internal transmission components such as the feeding plate 4 and the support plate 10 from dust and debris contamination, while preventing operators from contacting moving parts and causing safety accidents. The housing 3 has an internal cavity, and the internal sides of the cavity are... The feeding plate 4 is rotatably connected to the shaft. As the core execution component for material conveying, the feeding plate 4 achieves the distance of pushing the material on the connecting line through the cooperation of the arc-shaped limiting groove and the limiting block 5. The feeding plate 4 has an arc-shaped limiting groove inside, and the limiting block 5 is slidably connected inside the limiting groove. The limiting block 5 accurately limits and guides the movement trajectory of the feeding plate 4. The cylindrical structure cooperates with the arc-shaped limiting groove to ensure that the feeding plate 4 can only swing along the set arc trajectory. The bottom end of the limiting block 5 is connected to the inner wall of the outer shell 3, and the top end of the feeding plate 4 is equipped with a transmission component. The top of the outer casing 3 has a feeding groove, and a storage box 11 is fixed above the feeding groove. The storage box 11 is used to store the terminal or wire material to be processed. Its inner wall is arc-shaped to allow the material to enter the feeding roller 12 smoothly. The feeding roller 12 is rotatably connected to the bottom of the storage box 11. The feeding roller 12 realizes the quantitative feeding of the material by rotating. The strip groove is used to accommodate a single wire. When rotating, the wire in the groove is brought out and falls into the feeding groove at the top of the outer casing 3. The two sides of the feeding roller 12 are connected to the driving component for feeding through the storage box 11 via rotating rods. The front and rear sides of the outer casing 3 are symmetrically provided with through slots, and the position of the through slots corresponds to the feed port of the terminal machine 2. A material support plate 10 is fixed in the center of the inner casing 3. The material support plate 10 is located between the feeding plates 4 and corresponds to the through slot of the outer casing 3. It is used for feeding and picking up materials. The material support plate 10 serves as a temporary bearing platform for materials to fall from the feeding groove of the storage box 11.

[0016] The transmission assembly includes a pull rope 6, which is rotatably connected to the top of the feeding plate 4. The pull rope 6 acts as a force transmission component, converting the linear motion of the transmission rod 7 into the swinging motion of the feeding plate 4, thus achieving effective power transmission. The front end of the pull rope 6 is fixed with the transmission rod 7, which converts the manual driving force of the pull plate 9 into linear motion and transmits it to the feeding plate 4 through the pull rope 6, thereby realizing the swinging feeding of the feeding plate 4. The outer wall of the transmission rod 7 is fitted with a limiting groove 8, and the side surface of the limiting groove 8 is connected to the outer shell 3. The limiting groove 8 guides and limits the movement of the transmission rod 7, ensuring that the transmission rod 7 can only perform linear reciprocating motion along the axial direction. The front end of the transmission rod 7, which passes through the outer shell 3, is connected to a pull plate 9. The pull plate 9 acts as a manual operating component for the operator, who pushes and pulls the transmission rod 7 by gripping it, thus providing a power source for the transmission rod 7.

[0017] The drive assembly includes a turntable 13, which is located on the front surface of the storage bin 11. The back of the turntable 13 is connected to the rotating rod on the front surface of the feeding roller 12. The turntable 13 serves as the manual drive component for the feeding roller 12. The operator rotates the turntable 13 to drive the feeding roller 12 to rotate, thus achieving the feeding action. Pointers 14 are located on both the upper and lower sides of the turntable 13. The pointers 14 are aligned with the scale lines of the turntable 13 to provide a visual reference for the operator, facilitating accurate reading of the rotation angle of the turntable 13. The back of the pointers 14 is connected to the storage bin 11. Strip-shaped grooves are formed on both sides of the feeding roller 12, and these grooves are used for feeding the connecting line. A torsion spring is machined inside the connection between the feeding plate 4 and the outer casing 3, and the torsion spring is used to reset the feeding plate 4.

[0018] Working principle: When using a terminal wire connection component, the user first puts the terminal wire into the storage box 11, and then rotates the turntable 13 to drive the feeding roller 12 to rotate synchronously. The pointers on the front surface of the storage box 11 located on the upper and lower sides of the turntable 13 form a visual reference with the scale lines on the surface of the turntable. The operator can read the rotation angle of the turntable 13 through the pointers, and thus accurately control the rotation amplitude of the feeding roller 12. When the feeding roller 12 rotates, the strip grooves on both sides of it rotate together. The grooves receive a single terminal wire from the storage box 11. As the feeding roller 12 continues to rotate, the terminal wire in the groove is brought out and detached from the storage box, falling along the feeding groove at the top of the outer shell 3 onto the support plate 10 at the center of the inner shell. The support plate 10 serves as a temporary support platform for the terminal wire, and its position corresponds to the through slots and terminal machine feed inlet on the front and rear sides of the outer shell, preparing for subsequent feeding. After the terminal wire falls onto the support plate 10, the pull plate in the transmission assembly serves as a manual operation component. The operator holds the pull plate 9 and applies a forward pulling force to drive the transmission rod 7, which is fixedly connected to the pull plate 9, to move axially. The limiting groove block 8 sleeved on the outer wall of the transmission rod 7 is fixedly connected to the outer shell 3, providing precise guidance and limiting of the movement trajectory of the transmission rod 7. The position ensures that the transmission rod 7 can only move in a straight reciprocating motion along the axial direction. The end of the transmission rod 7 away from the pull plate is fixedly connected to the pull rope 6. The linear motion of the transmission rod 7 is converted into the tension of the pull rope 6. The pull rope 6 drives the feeding plate 4, which is rotatably connected to it, to swing in an arc around the shaft. The arc-shaped limiting groove opened inside the feeding plate slides in cooperation with the limiting block 5 fixed to the inner wall of the outer shell. The cylindrical structure of the limiting block 5 and the arc-shaped limiting groove form a guide, ensuring that the feeding plate 4 can only move along the set arc trajectory, thereby ensuring the accuracy of the feeding plate 4 in pushing the terminal wire. When the feeding plate rotates onto the feeding plate 4, the arc edges on both sides push the terminal wire forward. Since the position of the through groove corresponds to the feed port of the terminal machine 2, the terminal wire smoothly enters the feed port of the terminal machine under the pushing force of the feeding plate 4, completing the feeding operation.
