A self-locking sealing connector and a navigation light cable containing the connector

Abstract

This invention discloses a self-locking sealing joint, comprising a second joint assembly, characterized in that it further comprises a first joint assembly that is inserted into and mates with the second joint assembly. The first joint assembly includes a sleeve structure, a filling structure, and a self-locking conductor structure. The sealing metal synchronously adheres to the contact surface of the second joint assembly during assembly and seals the sleeve structure as it moves axially toward the second joint assembly. The sleeve structure is snapped and locked into the second joint assembly. The driven block compresses the soft package, causing it to deform. The material inside the soft package, after being compressed, flows into the self-locking conductor through a feed pipe, filling the internal gaps. This invention, by employing a specially designed self-locking conductor structure and a locking structure working together, can apply a stable and reliable locking constraint force to the conductor. Compared to traditional structures that rely on friction for limiting and fixing, this structure can withstand greater axial tensile loads.

Description

Technical Field

[0001] This invention relates to the field of cable joints, and in particular to a self-locking sealing joint and a navigation light cable containing the joint. Background Technology

[0002] Navigational lights primarily serve functions such as on-site path marking, slope indication, and boundary warning. Currently, the industry has completed a comprehensive upgrade of light sources, gradually replacing traditional halogen lamps with LED light sources. LED navigational lights also place significantly higher demands on the circuit stability and protection performance of power supply lines. Since the length and specifications of the connecting cables are limited, cable joints are generally required to connect multiple cable segments during on-site wiring and equipment networking construction. At present, the industry generally uses male and female plug-in cable connectors. The sealing structure of such connectors mostly relies on traditional silicone and rubber sealing rings to achieve waterproof and dustproof sealing. However, navigation lights are mostly used in complex outdoor working environments such as open-air, humid coastal areas, large temperature differences between day and night, high salt spray, and windy sand. Traditional rubber and silicone sealing rings are prone to hardening, cracking, elasticity loss, aging and failure. Long-term use of seals can lead to aging and failure, resulting in a significant reduction in the sealing performance of the joint. External moisture, humidity, and dust can easily penetrate into the joint cavity, causing various faults such as decreased circuit insulation, short circuits, poor connection, and abnormal signal transmission. In addition, existing conventional male and female joints only use a single sealing ring structure, lacking multiple sealing protection and locking reinforcement structures. After the joint is connected, its overall tensile and vibration resistance is weak. At the same time, the metal contacts inside the joint are prone to deformation during repeated disassembly and assembly, resulting in a reduction in the effective contact area and a decrease in current transmission efficiency. This fails to meet the requirements of high reliability, long service life, and stable operation in all weather conditions for LED navigation lights. To this end, a self-locking sealing connector and a navigation light cable containing the connector are provided. Summary of the Invention

[0003] In view of the technical problems existing in the prior art, the present invention is proposed.

[0004] Therefore, the present invention aims to solve the technical problems of the prior art, which are that the outdoor environment causes traditional joints to age faster and have poor tensile strength.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a self-locking sealing joint, comprising a second joint assembly, characterized in that it further comprises: A first connector assembly that is plugged into the second connector assembly, the first connector assembly including a sleeve structure, a filling structure and a self-locking conductor structure, the filling structure including a protective shell, a driven block and a soft package and a feed tube, the self-locking conductor structure including a self-locking conductor; The self-locking conductor is inserted into the second connector assembly, and the combined self-locking conductor is deformed and locked under the pressure of the second connector assembly. The sealing metal is simultaneously attached to the contact surface of the second connector assembly and sealed during assembly. The sleeve structure moves axially toward the second connector assembly, and the sleeve structure is locked to the second connector assembly. During the movement of the sleeve structure, the driven block in the filling structure is moved synchronously. The driven block squeezes the soft package to deform it. After being squeezed, the material inside the soft package flows into the self-locking conductor through the feed pipe, and the material flowing into the self-locking conductor fills the internal gap.

[0006] As a preferred embodiment of the self-locking sealing joint of the present invention, the second joint assembly includes a limiting structure and a locking structure. The limiting structure includes a locking housing. The inner wall of the locking housing is provided with a connecting groove. The connecting groove is used in conjunction with a device. An adhesive block is provided on the inner side of the connecting groove.

[0007] As a preferred embodiment of the self-locking sealing joint of the present invention, the locking structure includes an insulating outer frame, a locking conductor is disposed inside the insulating outer frame, a through hole is disposed inside the locking conductor, and a conductive top block is disposed inside the through hole.

[0008] As a preferred embodiment of the self-locking sealing joint of the present invention, the self-locking conductor structure further includes a conductor block, a sealing metal is installed on the outer side of the conductor block, a self-locking conductor is installed on the front side of the conductor block, and a slot is provided in the center of the self-locking conductor.

[0009] In a preferred embodiment of the self-locking sealing joint of the present invention, a discharge hole is provided in the central part of the empty groove, and the discharge hole is connected to the feed pipe.

[0010] In a preferred embodiment of the self-locking sealing joint of the present invention, a through slide rod is provided inside the driven block, the two ends of the slide rod are fixedly installed on the inner wall of the protective shell, and an extrusion plate is provided at the bottom of the driven block.

[0011] In a preferred embodiment of the self-locking sealing joint described in this invention, the soft package is filled with liquid metal, and a one-way port is provided at the contact port between the soft package and the feed pipe.

[0012] In a preferred embodiment of the self-locking sealing joint of the present invention, the sleeve structure includes a locking sleeve, on which a magnetic element is provided, and the magnetic element is used in conjunction with the driven block.

[0013] To solve the above-mentioned technical problems, the present invention also provides the following technical solution: including a self-locking sealing joint; and a navigation light cable, including: As a preferred embodiment of the self-locking sealing joint and the navigation light cable containing the joint described in this invention, wherein: the cable is installed at both ends of the first joint assembly and the second joint assembly, the cable includes conductive wires, and the outer side of the conductive wires is wrapped with an electromagnetic shielding layer.

[0014] As a preferred embodiment of the self-locking sealing joint and the navigation light cable containing the joint described in this invention, wherein: the outer side of the electromagnetic shielding layer is wrapped with an armor layer, the armor layer is embedded with metal wires, and the outer side of the armor layer is wrapped with an outer sheath.

[0015] The beneficial effects of this invention are as follows: This solution, through the cooperation of a specially designed self-locking conductor structure and a locking structure, can apply a stable and reliable locking constraint force to the conductor. Compared with the traditional structure that relies on friction to achieve limiting and fixing, this structure can withstand a greater axial tensile load. At the same time, the whole can form a stable self-locking mechanism, which can prevent the device from loosening or separating during long-term use, and significantly improve the tensile strength and connection stability of the overall structure.

[0016] Filling the self-locking conductor structure and locking structure with liquid metal can fully fill various tiny gaps at the conductor joint, compensating for voids caused by contact surface deformation. This fundamentally avoids problems such as poor contact and increased contact resistance caused by interface gaps and contact surface deformation. Furthermore, the excellent conductivity of liquid metal optimizes current transmission, reduces heat generation, and further improves the long-term reliability of the connection structure. Compared to traditional interlocking methods, the connection is more stable and better suited for high-current cable connections, with less heat generation at the connection point, reducing the technical problem of aging of other seals due to overheating. Meanwhile, a sleeve structure is added to the outer wall of the device to protect the internal metal components and improve the overall sealing performance; and an adhesive block is set at one end to fix and seal the protective shell by adhesive, further enhancing the sealing performance and structural stability of the device and effectively preventing it from falling off during use.

[0024] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention.

[0025] Example Reference Figure 1-7 This embodiment provides a self-locking sealing connector and a navigation light cable containing the connector, including a second connector assembly 200, and further including: The first connector assembly 100 is snapped into the inner wall of the second connector assembly 200. The first connector assembly 100 includes a sleeve structure 101, a filling structure 102, and a self-locking conductor structure 103. The filling structure 102 includes a protective shell 102a, a driven block 102c, a soft package 102d, and a feed pipe 102f. The soft package 102d is made of soft silicone material. The self-locking conductor structure 103 includes a sealing metal 103a, a self-locking conductor 103b, a conductor block 103c, an empty groove 103d, and a discharge hole 103e. The self-locking conductor structure 103 is connected to the second connector assembly 200. After the connection is complete, the self-locking conductor 103b deforms, and the sealing metal 103a forms a seal with the second connector assembly 200. The sleeve structure 101 needs to be manually driven to move towards the second connector assembly 200. The magnetic element 101b inside the sleeve structure 101 drives the driven block 102c, causing the sleeve structure 101 to engage and seal with the second connector assembly 200. The sleeve structure 101 drives the driven block 102c to move synchronously. The driven block 102c is equipped with... There are magnetic components that work in conjunction with the magnetic component 101b, and all of them use boron magnets, which can effectively ensure the driving force. The driven block 102c squeezes and deforms the soft package 102d. The soft package 102d is filled with a large amount of liquid gold material. Liquid gold usually refers to a low melting point metal alloy that is liquid at room temperature. It is usually a gallium-based alloy. This metal has good conductivity, which effectively ensures full contact of the device connector. At the same time, it does not have any magnetism, so it is not affected by the magnetic component. The material in the soft package 102d flows into the self-locking conductor 103b through the feed pipe 102f. The material entering the self-locking conductor 103b fills the gaps. The second connector assembly 200 includes a limiting structure 201 and a locking structure 202. The limiting structure 201 includes a locking housing 201a. The inner wall of the locking housing 201a is provided with a connecting groove 201b, which is used in conjunction with 101. An adhesive block 201c is provided on the inner side of the connecting groove 201b. The surface of the adhesive block 201c is covered with a sealing film, which needs to be removed before actual use. The adhesive block 201c is made of high-strength adhesive, preferably AB glue, which has good water resistance and aging resistance to avoid premature aging during use. In the case of aging, it can directly form a complete sealing connection position to prevent water and steam from entering, increase the strength of the device. The locking structure 202 includes an insulating outer frame 202a, a locking conductor 202b is provided inside the insulating outer frame 202a, a through hole is provided inside the locking conductor 202b, and a conductive top block 202c is provided inside the through hole. The insulating outer frame 202a and the sealing metal 103a adopt a sealing structure. The insulating outer frame 202a is preferably made of plastic material to prevent liquid metal in the sealing metal 103a from flowing out and to ensure full contact between the two joints. The self-locking conductor structure 103 also includes a conductor block 103c. A sealing metal 103a is installed on the outside of the conductor block 103c, and a self-locking conductor 103b is installed on the front of the conductor block 103c. The self-locking conductor 103b, in cooperation with the conductive top block 202c, can be lifted and deformed to lock into the locking conductor 202b, forming a self-lock. A slot 103d is provided in the center of the self-locking conductor 103b, and a discharge hole 103e is provided in the center of the slot 103d. The discharge hole 103e is made of the same material as the self-locking conductor 103b and is connected to the feed pipe 102f. The driven block 102c is provided with... A through-type slide bar 102b is provided, with both ends of the slide bar 102b fixedly installed on the inner wall of the protective shell 102a. A squeezing plate is provided at the bottom of the driven block 102c, which can squeeze the soft package, thereby squeezing the liquid in the soft package into the one-way port 102e. The soft package 102d is filled with liquid metal. A one-way port 102e is provided at the contact port between the soft package 102d and the feed pipe 102f. It is best to use a one-way plastic valve for the one-way port 102e to avoid the liquid metal returning. The sleeve structure 101 includes a locking sleeve 101a, and a magnetic element 101b is provided on the locking sleeve 101a. The magnetic element 101b is used in conjunction with the driven block 102c. Cable 300 is installed at both ends of the first connector assembly 100 and the second connector assembly 200. Cable 300 includes conductive wire 305. The conductive wire 305 is wrapped with an electromagnetic shielding layer 304 to increase stability. The electromagnetic shielding layer 304 is usually covered with conductive coating. The electromagnetic shielding layer 304 is wrapped with an armor layer 302 to increase the overall strength of the device. The armor layer 302 and the inner metal wire 303 are collectively referred to as the armor layer, thereby increasing the overall service life of the device. The armor layer 302 is embedded with metal wires 303 to further enhance its structural strength. The armor layer 302 is wrapped with an outer sheath 301. The outer sheath 301 is usually a large amount of insulating material and a corrosion-resistant and aging-resistant rubber outer sheath.

[0026] This embodiment has the following workflow: In use, the first connector assembly 100 is first inserted into the second connector assembly 200. During the engagement of the first connector assembly 100 and the second connector assembly 200, the self-locking conductor 103b enters the locking conductor 202b. At this time, the conductive top block 202c in the locking conductor 202b enters the empty slot 103d in the self-locking conductor 103b, and simultaneously deforms the locking conductor 202b, thus locking it in the locking conductor 202b. At this time, the sleeve structure 101 is manually driven to make the sleeve structure 101 engage and seal with the limiting structure 201. During the movement of the sleeve structure 101, the driven block 102c is driven by the magnetic component 101b. At this time, the soft package 102d is squeezed by the driven block 102c, and the liquid metal in the soft package 102d flows into the feed pipe 102f and then enters the locking conductor 202b, deforming it and filling it in the locking conductor 202b, thus avoiding the problem of poor contact.
