Description

Technical Field

[0001] This invention relates to the field of cable connection technology, and specifically to a fusion-bonded reconnector for cross-linked cables. Background Technology

[0002] Cross-linked cables are a type of cable whose insulation layer is made of cross-linked materials, the most common of which is cross-linked polyethylene. Through specific processing methods, the linear molecular structure of polyethylene material is transformed into cross-linked polyethylene with a three-dimensional network branch structure, thereby improving the cable's heat resistance, mechanical properties, and electrical properties. Cross-linked cables are widely used in power distribution networks, industrial equipment, and other fields that require high-capacity power. However, due to limitations in production and transportation conditions, the length of a single cross-linked cable is limited and cannot meet the usage requirements during circuit laying. Therefore, during the laying process, it is often necessary to connect multiple cross-linked cables end to end.

[0003] Traditional crimping and welding methods are prone to loosening during long-term operation due to material fatigue, thermal expansion and contraction, etc., which can lead to increased contact resistance, overheating, or even short circuits. Many joint designs fail to effectively isolate moisture and humidity, and long-term exposure to humid environments can easily cause corrosion of internal metal components, affecting electrical performance and safety. Once a joint fails, it often requires professional disassembly and reconnection, which is not only time-consuming and labor-intensive but may also cause secondary damage to the cable itself. Some joint designs do not consider self-locking functions, making the joints prone to loosening under vibration or external force, increasing safety hazards.

[0004] Therefore, the present invention provides a fusion-bonded reconnector for cross-linked cables to solve the above problems. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the prior art, the present invention provides a fusion-bonded reconnection cross-linked cable straight connector to solve the problem of avoiding the phenomenon of detachment or failure caused by unstable connection at the connector, and to achieve functions such as self-locking and waterproofing.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A fusion-bonded cross-linked cable straight connector includes: two cables to be fused, each cable having an internal battery core; an insulating connection component composed of multiple layers, located on the outer wall of a cut-open battery core; a first connector comprising an outer fixing sleeve, a first fixing ring, a first connecting ring, and an inner fixing sleeve, the inner fixing sleeve being fixedly connected to one end of the outer fixing sleeve, the first connecting ring located on the outer wall of the inner fixing sleeve, and a fastening nut threaded onto the outer wall of the outer fixing sleeve; and a second connector comprising an outer fixing sleeve, a second fixing ring, a second connecting ring, and an inner fixing sleeve, the second connecting ring located on the outer wall of the inner fixing sleeve. The second fixing ring is located on the outer wall of the outer fixing sleeve, and the first connector matches the second connector. This device cuts open the outer wall of the two cables and welds the two ends of the two cores together, so that the structure of the two welded cores is consistent with that of the original cores. This achieves a tight connection between the two welded cores and the original cable, avoiding the phenomenon of movable ends. This ensures that multiple cables will not fail due to the connection with the connector after being connected in pairs, thus meeting the needs of actual production and transportation. After connection, the device, through the setting of the first connector and the second connector, can achieve the function of inserting and fixing the outer wall after the two cables are welded. During insertion, the outer wall of the cable is fixed, which can achieve the function of self-locking, sealing and water blocking, and avoid the phenomenon of falling off due to vibration.

[0007] Preferably, a water-blocking ring is fixedly installed on the outer wall of the second connecting ring, and a snap-fit ​​cavity is opened inside the second connecting ring. The snap-fit ​​cavity is interconnected with the self-locking groove, which is located on the outer wall of the second connecting ring. A top plate is connected to the outer wall of the second connecting ring in a staggered manner with the self-locking groove. The first connecting ring and the second connecting ring have the same structure, and the top plate on the outer wall of the first connecting ring matches the self-locking groove on the second connecting ring. The first connecting ring and the second connecting ring of this device match each other, and the two are connected to the self-locking groove through the top plate.

[0008] Preferably, the inner fixing sleeve has a clamping arc plate slidably connected inside, and there are multiple clamping arc plates. A fixing block is fixedly installed on the outer wall of the clamping arc plate. The snap-fit ​​cavity has a sliding abutment plate slidably connected inside, and the thickness of the abutment plate decreases sequentially from the outside to the inside. The abutment plate matches the fixing block. After the battery core is welded, the cable is passed through the outer fixing sleeve and the inner fixing sleeve, so that the welded end is located inside the two inner fixing sleeves. At this time, to avoid shaking of the connection end and instability caused by external vibration, the device connects the first connecting ring and the second connecting ring to achieve a fixing effect. When the two rings are connected, the outer walls of the two rings... The top plate will be aligned with the self-locking groove and inserted. At this time, the top plate will abut against the top inclined plate, and the top inclined plate will move inward, which in turn will cause the fixing block to move the clamping arc plate inward. The clamping arc plate clamps and fixes the fused cable. In order to facilitate the fixation of the fused end and avoid the phenomenon of the movable end, this device can be fixed by the first connecting ring and the second connecting ring after the fusion is completed, realizing the self-locking function and protecting the outer wall of the cable.

The push-off inclined ring inside the second fixing ring is in the opposite direction to that inside the first fixing ring. In the initial state, the second fixing ring... When the pressing shaft is at its uppermost position, it abuts against the smaller diameter end of the abutting inclined ring. When the abutting shaft is displaced inward under force, the abutting diameter of the abutting inclined ring against the pressing shaft increases, thereby causing the pressing shaft to displace outward. At the same time, the pressing shaft inside the first fixed ring of this device is at its uppermost position, abutting against the smaller diameter end of the abutting inclined ring.

The device features a threaded connection with a stop nut. When the nut slides, the stop shaft on the second fixing ring is pushed against, causing the lower pressure shaft to move the fastening arc plate inward. At this time, the hinge plate clamps the outer wall of the cable, the angle of the hinge plate decreases, the extension spring is compressed, and the locking block engages with the cross slot. This device uses a hinge plate to fix the outer end of the fusion splice cable, achieving an automatic locking function. It also reduces vibration and prevents detachment. After the hinge plate is pressed and locked, the locking block engages with the cross slot, achieving a limiting function. By fastening the threaded arc plate and the stop nut, the device can fix the outer end of the fusion splice cable, achieving simultaneous fixation of the external end and the fusion splice end.

Through multiple sealing and fixing, damage caused by long-term use or outdoor weather is avoided, ensuring the stability of the cable.

[0016] The beneficial effects of this invention are as follows: 1. This device cuts open the outer walls of two cables and fuses the two ends of the two battery cores together, making the structure of the two fused battery cores consistent with the original battery cores. This achieves a tight connection between the two fused battery cores and the original cables, avoiding the phenomenon of loose ends. This ensures that multiple cables connected in pairs will not fail due to the connection with the joint, thus meeting the needs of actual production and transportation.

At the same time, this device can reduce vibration and prevent detachment. After the hinge plate is pressed and snapped, the snap-fit ​​block of this device engages with the cross-shaped snap-fit ​​groove to realize the function of limiting position. This device can fix the outer end of the fusion splice cable by tightening the threaded arc plate and the abutment nut, realizing the simultaneous fixation of the external end and the fusion splice end.
