Description

Technical Field

[0001] This utility model specifically relates to a lead wire assembly that facilitates adjustment of insertion depth. Background Technology

[0002] In electronic components, leads are conductive parts that connect the component to external circuits, and are typically made of metal. The primary function of leads is to provide electrical connections, enabling electronic components to transmit signals and supply power to other components or circuit boards. The design, materials, and connection methods of leads have a significant impact on the performance and reliability of electronic components. Their basic functions are electrical connection and mechanical support. Common lead types include through-hole leads, surface mount leads, and flexible leads.

[0003] Traditional lead-in assemblies typically employ a fixed-depth design, making them unadjustable to meet specific needs. This design often fails to meet the requirements for precise control in different application scenarios. While some lead-in assemblies allow manual adjustment of the insertion depth, the operation is complex and lacks precise scale indications, resulting in time-consuming and error-prone adjustments. Furthermore, after adjusting the insertion depth, traditional lead-in assemblies may exhibit stability issues, easily shifting or loosening, affecting the accuracy of measurements or operations.

[0004] Therefore, it is necessary to invent a lead assembly that facilitates adjustment of the insertion depth to solve the above problems. Utility Model Content

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-6 The lead wire assembly shown includes a lead wire body 1, a telescopic lead wire 2 installed inside the lead wire body 1, a base 3 at the tail of the lead wire body 1, and a wire 4 connected to the tail of the base 3.

[0029] Specifically, the lead body 1 has a telescopic cavity 11 inside, and moving grooves 12 are provided on both sides of its outer wall. A limiting component 5 is provided at the top of the moving groove 12. The moving grooves 12 on both sides are symmetrically arranged, and a number of evenly spaced locking grooves 13 are provided on one side of the moving groove 12, and a scale 14 is provided on the other side.

[0030] Specifically, the telescopic lead 2 is set inside the telescopic cavity 11, and a rotating disk 21 is provided on its top. The lower part of the telescopic lead 2 rotates at the bottom of the rotating disk 21. Positioning blocks 22 are provided on both sides of the bottom of the rotating disk 21. The positioning blocks 22 are placed in the moving slots 12 on both sides and move up and down. A compression spring 23 is provided between the top of the rotating disk 21 and the top of the inner side of the telescopic cavity 11. The compression spring 23 restrains the telescopic lead 2 inside the telescopic cavity 11.

[0031] In this embodiment, the lead wire body 1 has a telescopic cavity 11 inside, symmetrical moving grooves 12 on both sides of the outer wall, a limiting component 5 on the top, a locking groove 13 on one side, and a scale 14 on the other side. The telescopic lead wire 2 is placed in the telescopic cavity 11, a rotating disk 21 is installed on the top, and positioning blocks 22 are provided on both sides of the bottom. The positioning blocks 22 move up and down in the moving grooves 12. The base 3 is located at the tail of the lead wire body 1 and connects to the wire 4. The limiting component 5 includes a limiting post 51 and an adjusting knob 52. The limiting post 51 is threaded into the through hole 16, and the adjusting knob 52 is placed in the adjusting groove 15.

[0032] Reference Figure 5-6 The lead wire body 1 has adjustment grooves 15 on both sides above the moving groove 12. The lower side of the adjustment groove 15 has a through hole 16 and the upper side has a receiving hole 17. The through hole 16 and the receiving hole 17 are installed together with the limiting component 5. The limiting component 5 acts on the top surface of the positioning block 22 through the through hole 16 and restricts the movement of the positioning block 22, that is, fixes the telescopic lead wire 2.

[0033] Reference Figure 4 The limiting component 5 includes a limiting post 51, which is disposed inside the through hole 16 and the receiving hole 17. An adjusting knob 52 is also installed on the outer wall of the limiting post 51. The adjusting knob 52 is placed in the adjusting groove 15. The depth of the receiving hole 17 is at least sufficient to meet the overall length of the limiting post 51. The height of the adjusting groove 15 exceeds the thickness of the adjusting knob 52. Matching threads are provided on the outer wall of the limiting post 51 and the inner wall of the through hole 16.

[0034] Reference Figure 1-3 The length of the positioning block 22 does not exceed the outer side of the moving groove 12. The positions of the locking grooves 13 on both sides are symmetrical and match the rotation direction of the positioning block 22. The width of the locking groove 13 matches the width of the positioning block 22. The length of the positioning block 22 exceeds the length of the locking groove 13.

[0035] Specifically, the setting length of the scale 14 matches the overall length of the moving groove 12, and the overall length of the telescopic lead 2 is at least greater than the depth of the telescopic cavity 11.

[0036] In this embodiment, rotating the rotary disk 21 causes the positioning block 22 to move up and down within the moving groove 12, adjusting the insertion depth of the telescopic lead 2. The insertion depth of the lead is read through the scale 14 to ensure the accuracy of the adjustment. Rotating the adjustment knob 52 causes the limiting post 51 to move downward, acting on the top surface of the positioning block 22 through the through hole 16, thus restricting the movement of the positioning block 22. The positioning block 22 matches the locking groove 13, ensuring stability and reliability during locking. Rotating the adjustment knob 52 in the opposite direction causes the limiting post 51 to move upward, releasing the restriction on the positioning block 22. The positioning block 22 can then move freely within the moving groove 12 to readjust the lead depth.

[0037] In this embodiment, the user can easily adjust the insertion depth of the telescopic lead 2 through the cooperation of the rotating disk 21 and the positioning block 22 to meet the needs of different scenarios. The scale 14 provides an intuitive depth reading to ensure the accuracy of the adjustment.

[0038] Specifically, the limiting component 5, through the cooperation of the limiting post 51 and the adjusting knob 52, can firmly lock the position of the positioning block 22, preventing the telescopic lead 2 from shifting after adjustment. The width and length of the positioning block 22 match the locking groove 13, ensuring stability and reliability during locking and preventing the lead from loosening or falling off during operation.

[0039] In this embodiment, the design of the rotary disk 21 and compression spring 23 makes the lead wire depth adjustment operation flexible and effortless. The threaded engagement between the adjustment knob 52 and the limit post 51 allows the user to quickly lock or release the lead wire position, improving work efficiency.

[0040] Specifically, key components such as the lead body 1 and base 3 are made of high-strength materials, possessing excellent wear resistance and deformation resistance, thus extending the service life of the assembly. The compression spring 23 effectively mitigates the impact force on the lead during extension and retraction, reducing component wear and improving the durability of the assembly.

[0041] In this embodiment, the design of the scale and locking groove ensures precise control of the lead insertion depth, avoiding equipment damage or operational risks caused by excessive or insufficient insertion. The limiting component 5 further enhances the safety and stability of lead adjustment through a dual locking mechanism of threads and adjusting knob 52.

[0042] Specifically, the modular design makes component disassembly and replacement easier, reducing maintenance costs. Components such as limit component 5 and positioning block 22 adopt standardized designs, facilitating mass production and replacement, further reducing usage costs.

[0043] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
