Description

Technical Field

[0001] This utility model relates to the field of cabinet cable connector technology, and in particular to a double-sealed connector structure. Background Technology

[0002] When manufacturing server racks, it is necessary to connect cables to internal electrical components using connectors. However, ordinary connectors are prone to dust accumulation during connection, which can cause short circuits. Therefore, a double-sealed connector structure is used to connect cables to electrical components.

[0003] Existing technologies, such as patent CN214754376U, disclose a copper connector for cable connections. This patent includes cable A and cable B, with a connection protection mechanism installed at the connection point of cable A and cable B. A waterproof protection mechanism is provided on the outside of the connection protection structure. The connection protection mechanism includes a connector A end, a locking sleeve A, a connector B end, a locking sleeve B, and a locking element. The connector A end and the locking sleeve A are sleeved on the outside of cable B, and the locking sleeve A is located at one end of the connector A end and is threadedly connected to the connector A end. This utility model device solves the problem that existing equipment is easily damaged by human or natural forces during use. To save costs and time, most of them use connecting tools to connect broken or damaged cables together for continued use. However, this connection is relatively simple, the connection is not strong enough, and there are no protective measures, which can easily cause safety hazards.

[0004] In daily operation, the existing equipment has a problem with its overly simplistic sealing method, which allows moisture, dust, and other external substances to easily enter the equipment, making it difficult for the equipment to operate normally. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as low equipment sealing performance, which makes it difficult for equipment to function properly. This invention proposes a double-sealing joint structure.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a double-sealed joint structure, comprising a heat shrink tubing assembly, an insulating joint copper shell assembly, and a main body. The heat shrink tubing assembly includes a first heat shrink tubing, a second heat shrink tubing, a third heat shrink tubing, and a fourth heat shrink tubing. The insulating joint copper shell assembly includes a first insulating joint copper shell and a second insulating joint copper shell. The two main bodies are installed opposite each other. The first insulating joint copper shell is fixedly connected to the surface of the main body by a lead seal. The second insulating joint copper shell is fixedly connected to the other main body by a lead seal. The first heat shrink tubing is sleeved and connected at the connection between the first insulating joint copper shell, the lead seal, and the main body. The fourth heat shrink tubing is sleeved and connected at the connection between the second insulating joint copper shell, the lead seal, and the main body. An insulating segment is fixedly connected inside the first insulating joint copper shell. The first insulating joint copper shell and the second insulating joint copper shell are snapped together. A third heat shrink tubing connector is sleeved at the snap-together of the first and second insulating joint copper shells.

[0007] Furthermore, the main body contact end is connected via a crimping tube, and a shield is fitted onto the surface of the crimping tube. By setting the crimping tube, the main body can be connected, reducing the possibility of short circuits at the main body connection point during equipment use due to difficulty in quick connection.

[0008] Furthermore, an insulating joint rubber component is sleeved and connected to the surface of the shielding cover, and a first semiconducting strip is sleeved and connected to the surface of the insulating joint rubber component.

[0009] Furthermore, a second semiconducting strip is sleeved and connected to the surface of the first semiconducting strip, and a copper mesh is sleeved and connected to the surface of the second semiconducting strip.

[0010] Furthermore, an insulating tape is sleeved and connected to the surface of the copper mesh, and a second heat shrink tubing is sleeved and connected to the surface of the insulating tape.

[0011] Furthermore, an auxiliary component is fitted and snapped onto the surface of the copper shell of the first insulating joint. The auxiliary component includes a first mounting head and a second mounting head. The first mounting head is fitted and snapped onto the surface of the copper shell of the first insulating joint, and the second mounting head is fitted and connected to the surface of the main body.

[0012] Furthermore, a spring plate is fixedly connected between the first mounting head and the second mounting head.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, by using a first heat shrink tubing, a second heat shrink tubing, a third heat shrink tubing, and a fourth heat shrink tubing to seal different connection parts, a multi-seal structure is formed. Compared with the single sealing method in the prior art, this multi-heat shrink tubing sealing structure can more effectively reduce the entry of external substances such as moisture and dust into the joint, ensuring the normal operation of the equipment, reducing the probability of failure caused by poor sealing, and greatly improving the sealing performance of the joint.

[0015] In this utility model, the first mounting head and the second mounting head in the auxiliary component are respectively fitted onto the copper shell and the main body surface of the first insulating joint. The elastic plate provides elastic support. When the joint is subjected to external force, the elastic plate can absorb part of the external force, effectively buffering and dispersing the effect of external force on the joint, reducing the loosening or damage of the joint due to external force. The auxiliary component enhances the mechanical stability of the joint, improves the impact resistance of the equipment, and extends the service life of the equipment. Attached Figure Description

[0022] Please see Figures 1-5 This utility model provides a technical solution: a double-sealed joint structure, including a heat shrink tubing assembly 1, an insulating joint copper shell assembly 3, and a main body 12. The heat shrink tubing assembly 1 includes a first heat shrink tubing 101, a second heat shrink tubing 102, a third heat shrink tubing 103, and a fourth heat shrink tubing 104. The insulating joint copper shell assembly 3 includes a first insulating joint copper shell 301 and a second insulating joint copper shell 302.

[0023] The following section will describe the specific design and function of one type of double-sealing joint structure.

[0024] In this implementation scheme: two main bodies 12 are installed in a mating connection. The mating joint of the main bodies 12 adopts a precision end-face processing technology to ensure a smooth and flat contact surface, thereby reducing contact resistance and improving conductivity. The copper shell 301 of the first insulating joint is fixedly connected to the surface of the main body 12 by a lead seal 2. The lead seal 2 is made of high-purity lead alloy material, which has good flexibility and sealing performance. Under high temperature and high pressure environment, the lead seal 2 can tightly fill the gap between the copper shell 301 of the first insulating joint and the main body 12, forming the first physical sealing barrier, effectively reducing the entry of external moisture, dust and other impurities into the joint. The copper shell 302 of the second insulating joint is fixedly connected to the other main body 12 by the lead seal 2. The first heat shrink tube 101 is sleeved and connected to the connection between the copper shell 301 of the first insulating joint and the lead seal 2 and the main body 12. The first heat shrink tube 101 is made of radiation cross-linked polyolefin material, which has good heat shrink performance. After heating, the first heat shrink tube 101 will tightly wrap the connection, filling any micro-entities that may exist in the lead seal 2. Small gaps form a second layer of sealing protection, further enhancing the waterproof and moisture-proof effect. The fourth heat shrink tubing 104 is sleeved and connected to the connection between the second insulating joint copper shell 302 and the lead seal 2 and the main body 12. The first insulating joint copper shell 301 has an insulating segment 11 fixedly connected inside. The insulating segment 11 is made of high-strength, high-insulation epoxy resin material, which can effectively isolate conductors with different potentials and reduce leakage and short circuits. Its structure is reasonably designed and fits tightly with the first insulating joint copper shell 301, ensuring that it will not loosen or shift during long-term use. The first insulating joint copper shell 301 and the second insulating joint copper shell 302 are snapped together. The snapping joint adopts a concave-convex fit structure design. After precision processing, the snapping accuracy is high. This design not only facilitates installation and disassembly, but also forms a tight connection after snapping, effectively reducing the relative displacement between the two copper shells. The connector third heat shrink tubing 103 is sleeved at the snapping joint of the first insulating joint copper shell 301 and the second insulating joint copper shell 302.

[0025] Specifically, the contact end of the main body 12 is connected through the crimping tube 6. The crimping tube 6 is made of the same high-conductivity metal as the main body 12 and is cold-pressed using professional crimping equipment to ensure that the crimping tube 6 and the main body 12 are tightly bonded together to form a strong electrical connection. This connection method can effectively reduce contact resistance and ensure the stability and reliability of current transmission. A shielding cover 5 is fitted on the surface of the crimping tube 6. The shielding cover 5 is made of a metal material with high magnetic permeability, which can effectively shield external electromagnetic interference, reduce the impact of electromagnetic signals on power transmission, and also reduce the interference of electromagnetic fields generated inside the joint on external electronic equipment.

[0026] In this embodiment: by setting the pressure pipe 6, the main body 12 can be connected, which reduces the difficulty of quickly connecting the main body 12 during use and prevents short circuits at the connection of the main body 12.

[0027] Specifically, the surface of the shield 5 is covered with an insulating joint rubber component 4. The insulating joint rubber component 4 is made of silicone rubber, which has excellent insulation performance, aging resistance and weather resistance. It can fit tightly against the surface of the shield 5 to further enhance the insulation performance, and at the same time protect the shield 5 and reduce its external mechanical damage. The surface of the insulating joint rubber component 4 is covered with a first semiconducting strip 8.

[0028] Specifically, a second semiconducting strip 9 is sleeved and connected to the surface of the first semiconducting strip 8, and a copper mesh 10 is sleeved and connected to the surface of the second semiconducting strip 9. The copper mesh 10 has good conductivity and flexibility, which can evenly conduct the charge inside the joint, and at the same time play an auxiliary role in electromagnetic shielding, further enhancing the anti-interference ability of the joint.

[0029] Specifically, an insulating tape 7 is sleeved and connected to the surface of the copper mesh 10, and a second heat shrink tubing 102 is sleeved and connected to the surface of the insulating tape 7.

[0030] In this embodiment: an auxiliary component 13 is fitted and snapped onto the surface of the copper shell 301 of the first insulating connector. The auxiliary component 13 includes a first mounting head 131 and a second mounting head 133. The first mounting head 131 is fitted and snapped onto the surface of the copper shell 301 of the first insulating connector, and the second mounting head 133 is fitted and connected to the surface of the main body 12.

[0031] Specifically, a spring plate 132 is fixedly connected between the first mounting head 131 and the second mounting head 133. The spring plate 132 is made of a highly elastic alloy material and has good elastic recovery performance. When the joint is subjected to external impact or vibration, the spring plate 132 can absorb and buffer energy through its own elastic deformation, reduce the relative displacement between the first mounting head 131 and the second mounting head 133, thereby protecting the internal sealing structure and electrical connection of the joint from damage. At the same time, the elastic effect of the spring plate 132 can also compensate for the thermal expansion and contraction of the components caused by temperature changes to a certain extent, and maintain the tightness of the joint connection.

[0032] Working principle: During equipment installation, the first heat shrink tubing 101 is fitted onto the connection between the copper shell 301 of the first insulating joint, the lead seal 2, and the main body 12. The fourth heat shrink tubing 104 is fitted onto the connection between the copper shell 302 of the second insulating joint, the lead seal 2, and the main body 12. The second heat shrink tubing 102 is fitted over the rubber part 4 of the insulating joint, the first semi-conductive tape 8, the second semi-conductive tape 9, and the copper mesh 10. The third heat shrink tubing 103 is fitted onto the snap-fit ​​joint between the copper shell 301 and the copper shell 302 of the first and second insulating joints. When the heat shrink tubing is heated, it shrinks and fits tightly against the connection. By using the first heat shrink tubing 101, the second heat shrink tubing 102, the third heat shrink tubing 103, and the fourth heat shrink tubing 104 to seal different connection points, a multi-seal structure is formed. Compared with the single sealing method in the existing technology, this multi-seal structure of heat shrink tubing can more effectively reduce the entry of external substances such as moisture and dust into the joint, ensuring the normal operation of the equipment, reducing the probability of failure caused by poor sealing, and greatly improving the sealing performance of the joint.

[0033] When auxiliary component 13 is installed, the first mounting head 131 is fitted onto the surface of the copper shell 301 of the first insulating joint and snapped in place, while the second mounting head 133 is fitted onto the surface of the main body 12. The elastic plate 132 between the first mounting head 131 and the second mounting head 133 provides elastic support. The first mounting head 131 and the second mounting head 133 in auxiliary component 13 are respectively fitted onto the surfaces of the copper shell 301 of the first insulating joint and the main body 12. The elastic plate 132 provides elastic support. When the joint is subjected to external force, the elastic plate 132 can absorb part of the external force, effectively buffering and dispersing the effect of external force on the joint, reducing the loosening or damage of the joint due to external force. Auxiliary component 13 enhances the mechanical stability of the joint, improves the impact resistance of the equipment, and extends the service life of the equipment.
