Description

Technical Field

[0001] This utility model belongs to the field of packaging technology, specifically relating to an anti-pull-out solder wire assembly for a power supply. Background Technology

[0002] In the field of electronic equipment, power supplies are a fundamental and critical component, connecting to external power sources or load devices via cables. Currently, traditional power supply cable connections have significant drawbacks. First, cables are typically led out and fixed directly from inside the power supply housing, or have only simple outlets. During use, the cables are highly susceptible to excessive stress due to accidental pulling or frequent bending. This stress is directly transmitted to the solder joints on the circuit board, easily leading to solder joint cracking, poor soldering, or even complete detachment, causing power circuit breaks or poor contact, severely impacting the reliability and lifespan of the equipment.

[0003] Secondly, to adapt to different usage scenarios, some devices require longer cables, making the storage and management of excess cables a challenge. Randomly tangled cables are not only messy and unsightly, but improper handling during storage and retrieval can also exacerbate wear and damage. Existing storage solutions often rely on manual operation, which is cumbersome and inefficient, lacking a fast, automated recycling and limiting mechanism.

[0004] Furthermore, while some designs employing spiral-shaped wires for stretchability improve ductility and resilience to some extent, the spiral tube itself undergoes metal fatigue or plastic deformation over time, leading to weakened resilience and an inability to automatically retract, thus losing its original storage advantage. Current technologies lack effective auxiliary rebound and forced retraction structures, failing to ensure that the wire maintains its smooth stretching function after long-term use. Utility Model Content

[0005] The purpose of this invention is to provide an anti-pull-out solder wire assembly for a power supply, which aims to solve the problems mentioned in the background art.

[0006] A pull-out resistant solder wire assembly for a power supply includes,

[0007] Power supply housing;

[0008] A protective assembly is located on both sides of the outer wall of the power supply housing. The protective assembly includes a housing, a spiral tube, a cable, an internally threaded cylinder, a guide cylinder, an elastic cord, and a drive assembly. The housing is rotatably inserted into the center of one side of the outer wall of the power supply housing. One end of the spiral tube is fixedly located on the inner wall of the housing. The cable is embedded in the inner wall of the spiral tube. The internally threaded cylinder is rotatably embedded in the inner wall of the housing, with its internal thread groove matching the spiral tube. The guide cylinder is fixedly located on the inner wall of the housing. One end of the cable extends through the inner wall of the guide cylinder to the inner wall of the power supply housing. One end of the elastic cord is fixedly located at the center of the inner wall of the guide cylinder, and the other end of the elastic cord is wrapped around the outer wall of one end of the spiral tube. The drive assembly is located on the inner wall of the housing.

[0009] Furthermore, the drive assembly includes a housing motor, a drive gear, and a driven gear.

[0010] Furthermore, the storage motor is fixedly installed on the inner wall of the storage shell, and the drive gear is fixedly installed at the center of the outer wall of the output end of the storage motor.

[0011] Furthermore, the driven gear is fixedly disposed on the outer wall of one end of the internally threaded cylinder, and the driving gear and the driven gear are meshed and connected for transmission.

[0012] Furthermore, mounting brackets are fixedly installed on both sides of the inner wall of the power supply housing, and protective sleeves are embedded in the inner wall of the mounting brackets.

[0013] Furthermore, the protective sleeve is fitted onto the outer wall of one end of the cable.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By deploying the power supply housing to the designated working position, the spiral tube increases its resilience when the cable is pulled, allowing both the spiral tube and the cable to be pulled out of the housing together. This extends the cable's service distance and prevents sudden cable pulling from causing poor soldering or breakage at the connection points, thus improving the power supply's reliability and safety. When the spiral tube and cable are pulled out, the elastic cord provides assistance, preventing the spiral tube from aging and resulting in uneven rebound, ensuring long-term stability. When cable retrieval is required, the retrieval motor in the drive assembly rotates the drive gear, which in turn drives the internal threaded cylinder to rotate. This internal groove pulls the spiral tube back, achieving rapid retrieval and limiting, preventing the cable from being forcibly pulled out. The operation is simple and efficient. Furthermore, the mounting bracket and protective sleeve on the inner wall of the power supply housing, fitted onto one end of the cable, provide stable limiting and protection, further enhancing the component's durability and overall performance.

The housing 2 is rotatably inserted into the center of one side of the outer wall of the power supply housing 1. One end of the spiral tube 5 is fixedly set in the inner wall of the housing 2. The cable 6 is embedded in the inner wall of the spiral tube 5. The internally threaded cylinder 7 is rotatably embedded in the inner wall of the housing 2. The internal thread groove of the internally threaded cylinder 7 matches the spiral tube 5. The guide cylinder 8 is fixedly set in the inner wall of the housing 2. One end of the cable 6 extends through the inner wall of the guide cylinder 8 to the inner wall of the power supply housing 1. One end of the elastic rope 9 is fixedly set in the center of the inner wall of the guide cylinder 8. The other end of the elastic rope 9 is wrapped around the outer wall of one end of the spiral tube 5. The drive assembly is located in the inner wall of the housing 2.

[0028] In a specific embodiment of this utility model, the power supply housing 1 is first deployed to the designated working position. Then, when the cable 6 is pulled, the spiral tube 5 increases the resilience, allowing the spiral tube 5 and the cable 6 to be pulled out of the storage housing 2 together. This extends the service distance of the cable 6 and also avoids sudden pulling of the cable 6, which could cause the electrical terminals of the cable 6 to be pulled, resulting in poor soldering or breakage. When the spiral tube 5 and the cable 6 are pulled out of the storage housing 2 together, the elastic rope 9 provides assistance to prevent the spiral tube 5 from aging and causing uneven rebound. When it is necessary to retract the spiral tube 5, the storage motor 10 can be started, driving the drive gear 11 to rotate. The driven gear 12 drives the internal threaded cylinder 7 to rotate, pulling the spiral tube 5 back through the internal groove. This facilitates quick and easy storage and limiting, preventing the cable 6 from being forcibly pulled out.

[0029] Specifically, the drive components include a housing motor 10, a drive gear 11, and a driven gear 12.

[0030] In a specific embodiment of this utility model, the drive component can ensure stable power transmission.

[0031] Specifically, the storage motor 10 is fixedly installed on the inner wall of the storage shell 2, and the drive gear 11 is fixedly installed at the center of the outer wall of the output end of the storage motor 10.

[0032] In a specific embodiment of this utility model, the drive gear 11 is fixedly disposed at the center of the outer wall of the output end of the housing motor 10, which can ensure stable power output.

[0033] Specifically, the driven gear 12 is fixedly installed on the outer wall of one end of the internal threaded cylinder 7, and the driving gear 11 and the driven gear 12 are meshed and connected for transmission.

[0034] In a specific embodiment of this utility model, the driving gear 11 and the driven gear 12 are meshed and connected to ensure transmission accuracy.

[0035] Specifically, mounting brackets 3 are fixedly installed on both sides of the inner wall of the power supply housing 1, and protective sleeves 4 are embedded in the inner wall of the mounting brackets 3.

[0036] In a specific embodiment of this utility model, a protective sleeve 4 is embedded in the inner wall of the mounting bracket 3, which can achieve stable positioning.

[0037] Specifically, the protective sleeve 4 is fitted onto the outer wall of one end of the cable 6.

[0038] In a specific embodiment of this utility model, the protective sleeve 4 is fitted onto the outer wall of one end of the cable 6 to ensure stable protection.

[0039] Working principle:

[0040] First, the power supply housing 1 is deployed to the designated working position. Then, when the cable 6 is pulled, the spiral tube 5 increases the resilience, allowing the spiral tube 5 and the cable 6 to be pulled out of the storage housing 2 together. This extends the service distance of the cable 6 and also prevents sudden pulling of the cable 6, which could cause the electrical terminals of the cable 6 to be pulled, resulting in poor soldering or breakage. When the spiral tube 5 and the cable 6 are pulled out of the storage housing 2 together, the elastic rope 9 provides assistance to prevent the spiral tube 5 from aging and causing uneven rebound. When it is necessary to retract the spiral tube 5, the storage motor 10 can be started, driving the drive gear 11 to rotate. The driven gear 12 drives the internal threaded cylinder 7 to rotate, pulling the spiral tube 5 back through the internal groove. This facilitates quick and easy storage and limiting, preventing the cable 6 from being forcibly pulled out.
