Description

Technical Field

[0001] This utility model relates to the field of cable installation technology, specifically to an assembled multifunctional cable adapter device. Background Technology

[0002] In the power and communications industries, the reliability and adaptability of cable connection devices directly affect the safety of system operation. Traditional cable adapters suffer from several technical bottlenecks: First, their waterproof sealing structure is simplistic, relying solely on simple sealing rings, making them prone to water leakage in complex environments such as high humidity and rain erosion, leading to damage to internal electrical components. Second, their specification compatibility is insufficient; special adapters are required for cables of different outer diameters, resulting in low installation efficiency and high costs. Third, their connection stability is poor; ordinary plug-in structures are susceptible to loosening due to vibration and external pulling forces, and the conductive contacts do not consider temperature compensation, leading to increased contact resistance and overheating potential during long-term operation. Fourth, their environmental adaptability is limited; they lack effective heat dissipation and corrosion protection designs, making them prone to shell aging and performance degradation in high-temperature and highly corrosive environments. Utility Model Content

[0003] In order to overcome the shortcomings of existing technical solutions, this utility model provides an assembled multifunctional cable adapter device, which can effectively solve the problems raised in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A prefabricated multifunctional cable adapter includes a housing consisting of an upper shell and a lower shell, a multi-specification adapter mechanism disposed in the inner cavity of the housing, and a quick-connect assembly. The quick-connect assembly includes a waterproof plug-in seat disposed at the end of the housing and a matching guide groove. The connection between the waterproof plug-in seat and the housing is provided with a triple waterproof structure, which includes a first-level labyrinth waterproof groove, a second-level silicone sealing lip, and a third-level air pressure balance hole.

[0006] The multi-specification adapter mechanism includes cable fixing sleeves with different inner diameters distributed along the axial direction and an adaptive clamping structure.

[0020] 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.

[0021] like Figure 1-3 As shown, this utility model provides an assembled multifunctional cable adapter device, including a housing 1 composed of an upper shell 108 and a lower shell 109, a multi-specification adapter mechanism 2 disposed in the inner cavity of the housing 1, and a quick-connect assembly. The quick-connect assembly includes a waterproof plug-in seat 102 disposed at the end of the housing 1 and a matching guide groove. The connection between the waterproof plug-in seat 102 and the housing 1 is provided with a triple waterproof structure 101. The triple waterproof structure 101 includes a first-level labyrinth waterproof groove 104, a second-level silicone sealing lip 105, and a third-level air pressure balance hole 106.

[0022] The housing 1 consists of an upper shell 108 and a lower shell 109. The connection surface between the two is provided with a double sealing structure. The elastic sealing ring extending circumferentially along the housing 1 undergoes elastic deformation during installation due to the compression between the upper shell 108 and the lower shell 109. This tightly fills the gap between the connection surfaces, preventing external water, dust and other impurities from entering the inner cavity of the housing 1, thus providing a stable working environment for the internal mechanism.

[0023] When external water comes into contact with the connection between the waterproof connector 102 and the housing 1, the first-stage labyrinthine waterproof groove 104 comes into play. Its unique labyrinthine structure forces water to follow a complex path during the penetration process, increasing the water penetration resistance, prolonging the penetration time, and blocking most of the water from entering. If a small amount of water still breaks through the first-stage defense, the second-stage silicone sealing lip 105, with the good elasticity and sealing properties of silicone, tightly fits the connection gap between the connector and the housing 1, further preventing water from seeping in. At the same time, the third-stage air pressure balance hole 106 is used to balance the air pressure inside and outside the housing 1, avoiding the failure of the sealing structure due to the pressure difference between the inside and outside, and ensuring that good waterproof performance is maintained even under pressure change environments.

[0024] The triple waterproof structure 101, combined with the double sealing structure of the shell 1, forms a multi-layered, all-round waterproof system that can effectively prevent rainwater and moisture from entering the device. This ensures that the electrical connection parts and internal mechanisms are not corroded by water in harsh environments such as humid and rainy conditions, thereby improving the reliability and safety of the device.

[0025] The multi-specification adapter 2 includes cable fixing sleeves with different inner diameters distributed along the axial direction and an adaptive clamping structure. Each cable fixing sleeve is connected by a variable diameter connecting ring to form a stepped transition structure. The adaptive clamping structure includes multiple spring pins distributed on the inner wall of the cable fixing sleeve.

[0026] In this embodiment, cable retaining sleeves with different inner diameters are distributed axially and form a stepped transition structure through a variable-diameter connecting ring. When cables of different specifications are inserted, the cables can smoothly enter the corresponding retaining sleeves along the stepped structure. Multiple spring-loaded pins on the inner wall of the retaining sleeve automatically adjust the extension length and pressure of the pins according to the cable's outer diameter during cable insertion. When the cable's outer diameter is large, the spring-loaded pins are compressed, generating a reverse elastic force that tightly presses against the cable's outer wall; when the cable's outer diameter is small, the spring-loaded pins extend, similarly fixing the cable with appropriate pressure, thus achieving adaptive clamping for cables of different specifications.

[0027] The multi-specification adapter 2, through the design of cable fixing sleeves with different inner diameters, variable diameter connecting rings and spring pins, can quickly and easily adapt to a variety of different specifications of cables without replacing the entire device. Only the adapter mechanism needs to be adjusted according to the cable specifications, which greatly improves the versatility and flexibility of the device and reduces the cost of use and installation time.

[0028] The anti-disconnection mechanism 103 of the quick-connect assembly ensures a firm connection between the plug and the socket, preventing loosening or detachment due to vibration, external pulling, etc. The electrical connection structure 107 of gold-plated elastic contacts and temperature-compensated copper busbars ensures good conductivity, reduces contact resistance and heat generation, and improves the efficiency and stability of power transmission.

[0029] Furthermore, the housing 1 includes an upper housing 108 and a lower housing 109. The connection surface between the upper housing 108 and the lower housing 109 is provided with a double sealing structure, which includes an elastic sealing ring extending circumferentially along the housing 1. The housing 1 adopts an assembly design, and the connection between the upper housing 108 and the lower housing 109, as well as the slide rail structure of the multi-specification adapter mechanism 2, make the installation, disassembly, and adjustment of the device more convenient, facilitating on-site construction and subsequent maintenance.

[0030] Furthermore, the multi-specification adaptation mechanism 2 also includes a pressure equalization ring and a slide rail structure. The pressure equalization ring is connected to the side wall of the housing 1 through the slide rail structure. The slide rail structure includes a guide groove and a ball positioning assembly 110 that cooperates with the guide groove.

[0031] The pressure equalizing ring is connected to the side wall of the housing 1 via a slide rail structure. The guide groove in the slide rail structure provides sliding guidance for the pressure equalizing ring, and the ball positioning assembly 110 reduces friction during sliding, allowing the pressure equalizing ring to slide freely within the housing 1. When the cable is subjected to external tension or pressure, the pressure equalizing ring can evenly distribute the force to all parts of the housing 1, avoiding excessive local stress. Simultaneously, by sliding the pressure equalizing ring, the overall position of the multi-specification adapter mechanism 2 can be adjusted to accommodate cable connection requirements at different angles and positions.

[0032] Furthermore, the quick-connect assembly includes an anti-disconnection mechanism 103 and an electrical connection structure 107 consisting of gold-plated elastic contacts and temperature-compensated copper busbars. The anti-disconnection mechanism 103 also includes an elastic buckle and a matching unlocking push button disposed on the side wall of the connector.

[0033] The gold-plated elastic contact piece has excellent conductivity and wear resistance. When used in conjunction with the temperature-compensating copper busbar, it ensures a tight contact with the cable terminal during cable insertion, forming a stable electrical connection. The temperature-compensating copper busbar compensates for changes in contact resistance caused by temperature variations, ensuring stable conductivity. In the anti-disconnection mechanism 103, an elastic latch is located on the side wall of the connector. When the plug is inserted, the elastic latch engages with the matching slot, locking the plug to the connector and preventing it from falling out. To unlock, push the unlocking button to retract the elastic latch, allowing the plug to be easily removed.

[0034] Furthermore, the surface of the housing 1 is provided with a heat dissipation structure 3 and an anti-corrosion coating consisting of a bottom layer of anodized aluminum and a top layer of polytetrafluoroethylene coating. The heat dissipation structure 3 includes staggered rectangular heat dissipation fins 302 and ventilation guide grooves 301.

[0035] The staggered rectangular heat dissipation fins 302 on the surface of the housing 1 increase the contact area between the housing 1 and the air. When the device generates heat during operation, the heat is transferred through the housing 1 to the heat dissipation fins and then dissipated into the surrounding environment through air convection. The design of the ventilation guide grooves 301 guides airflow, accelerates heat dissipation, and ensures that the temperature of the device remains within a reasonable range during long-term operation. The bottom anodized aluminum layer has high hardness and corrosion resistance, effectively protecting the substrate of the housing 1; the surface polytetrafluoroethylene coating has excellent chemical corrosion resistance and non-stick properties, preventing various corrosive substances from eroding the housing 1 and extending the service life of the device.

[0036] Furthermore, it also includes an intelligent monitoring system, which includes a temperature and humidity sensor 111, a vibration monitoring module 112, and a data storage unit installed inside the housing 1. The intelligent monitoring system is wirelessly connected to a mobile terminal via a Bluetooth module.

[0037] A temperature and humidity sensor 111 installed inside the housing 1 monitors the temperature and humidity data inside the housing 1 in real time, while a vibration monitoring module 112 monitors the vibration of the device. This monitoring data is transmitted to a data storage unit for storage and simultaneously wirelessly transmitted to a mobile terminal via a Bluetooth module. Users can view the operating status of the device in real time through an application on the mobile terminal. When the temperature, humidity, or vibration parameters exceed preset thresholds, the mobile terminal will issue an alert to remind the user to perform timely maintenance and troubleshooting.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
