Description

Technical Field

[0001] This application relates to the field of wire harness processing, and in particular to a node sealing structure for connecting wire harnesses. Background Technology

[0002] In industrial applications, many devices are required to maintain their functionality under extreme conditions (such as high temperature, high humidity, and immersion in water), which places certain sealing and waterproofing requirements on various components of the equipment. For example, wire harnesses and cables provide power / signal transmission functions for the equipment, especially external wire harnesses and cables with wire harness connection nodes, whose nodes may even have a higher waterproofing rating than the equipment itself.

[0003] The existing Chinese utility model patent with publication number CN219268473U discloses a node sealing structure and a connecting harness; however, it still has the following shortcomings in practical use:

[0004] The document describes the installation of injection-molded brackets on the first and second wire harnesses. After melting, the injection-molded brackets fill the gaps between the first and second wires, further sealing the connection nodes. However, the injection-molded brackets cannot accommodate wire harnesses of different diameters, which limits the operation. Furthermore, the structure cannot secure the wire harnesses during installation and may move during installation or subsequent use. This movement could increase the gap between the sealing layer and the wire harness, thereby reducing sealing performance and making it easier for moisture, dust, and other contaminants to penetrate. Utility Model Content

[0005] To address the issues of not being able to accommodate wire harnesses of different diameters and not being able to secure the wire harnesses, this application provides a node sealing structure for connecting wire harnesses.

[0006] The node sealing structure for connecting wire harnesses provided in this application adopts the following technical solution:

[0007] A node sealing structure for connecting wire harnesses, characterized in that: it includes a sleeve, the inner wall of which is fixedly connected with a sealing layer, the node sealing structure is disposed at the connection between wire harness one and wire harness two, the wire harness one forms at least one first wire harness, the wire harness two forms at least one second wire harness, and the first wire harness and the second wire harness are electrically connected to form a connection point;

[0008] The sealing layer is provided with a sealing mechanism inside to ensure that the interior of the sealing layer is a sealed space;

[0009] The sealing layer is internally provided with a support mechanism for supporting wire harness one and wire harness two.

[0010] By adopting the above technical solution, the sleeve and sealing layer provide a protective environment for the connection point. This protection ensures that the connection point is not affected by the external environment, such as moisture, dust or other contaminants, thereby maintaining the stability and reliability of the electrical connection. The presence of the sealing mechanism ensures that a sealed space is formed inside the sealing layer. This sealing prevents the intrusion of moisture, gas or other harmful substances, protects the connection point from corrosion and damage, and extends the service life of the wire harness. The support mechanism inside the sealing layer provides necessary support for wire harness one and wire harness two. This support ensures that the wire harness maintains a stable position and shape at the connection point and prevents the connection from loosening or being damaged due to vibration or external force.

[0011] Preferably, the sealing mechanism includes a support plate fixedly connected to both ends of the sealing layer, a connecting column fixedly connected through the interior of the support plate, and an auxiliary cylinder fixedly connected to one side of the connecting column.

[0012] By adopting the above technical solution, the support plate is fixedly connected to both ends of the sealing layer, providing a solid support frame for the sealing layer and enhancing the stability of the entire sealing structure.

[0013] Preferably, the connecting post has a threaded hole on the side away from the auxiliary cylinder, a rubber ring one is fixedly connected to the outer surface of the connecting post, and a rubber ring two is fixedly connected to the side of the outer surface of the connecting post away from the rubber ring one.

[0014] By adopting the above technical solution, the threaded hole is used to connect the support mechanism, and the rubber ring one and rubber ring two serve as sealing elements, which can effectively fill the gap between the connecting post and the wire harness or sealing layer, preventing external pollutants such as moisture and dust from entering the sealing space, thereby enhancing the sealing performance of the entire sealing structure.

[0015] Preferably, the support mechanism includes a screw threaded into a threaded hole, and a circular plate is rotatably connected to the outer surface of the screw. A groove is formed on one side of the circular plate.

[0016] By adopting the above technical solution, the screw is connected to the threaded hole through the thread, which can firmly fix the support mechanism to the sealing layer or connecting column. This fixing method provides stable support and ensures the stability and reliability of the wire harness at the connection point. The groove opened on the circular plate allows it to slide or rotate to a certain extent. This adjustability enables the support mechanism to adapt to wire harnesses of different diameters, shapes or connection methods, and improves the versatility and flexibility of the sealing structure.

[0017] Preferably, a slide rod is slidably connected inside the slide groove, an arc-shaped plate is fixedly connected to the end of the slide rod away from the screw, and a slide column is fixedly connected to the side of the slide rod away from the circular plate.

[0018] By adopting the above technical solution, the design of the arc plate can better adapt to the bending shape of the wire harness, provide uniform support force, and prevent the wire harness from being subjected to excessive pressure or tension at the connection point.

[0019] Preferably, a circular plate two is rotatably connected to the outer surface of the screw, and an arc-shaped groove is formed on the inner circumference of the circular plate two.

[0020] By adopting the above technical solution, the arc-shaped groove opened inside the circular plate is used to control the length of the sliding plate, thereby adapting to wire harnesses of different diameters.

[0021] Preferably, a cylinder is fixedly connected to the side of the circular plate away from the slide rod.

[0022] By adopting the above technical solution, the cylinder is used to control the rotation of the circular plate.

[0023] Preferably, the sleeve and the interior of the sealing layer are fixedly connected by an injection hole.

[0024] By adopting the above technical solution, the design of the injection hole allows the sealing material to be easily injected into the gap between the sealing layer and the auxiliary cylinder. This grouting process can fill any potential gaps, ensuring a tight bond between the sealing layer and the sleeve, thereby improving the sealing performance.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By utilizing rubber rings one and two in the sealing mechanism, a sealed space is formed inside the sealing layer. This seal prevents the intrusion of moisture, gas, or other harmful substances, thereby protecting the connection points from corrosion and damage, extending the service life of the wiring harness. Furthermore, rubber rings one and two can absorb and disperse some stress, protecting the connecting posts and wiring harness from damage. Simultaneously, the elasticity of the rubber material can buffer vibration and impact, improving the durability of the sealing structure.

[0027] 2. The arc-shaped plate in the support mechanism provides necessary support for wire harness one and wire harness two. This support can ensure that the wire harnesses maintain a stable position and shape at the connection point and prevent the connection from loosening or being damaged due to vibration or external force.

[0028] 3. The sliding groove on the circular plate of the support mechanism allows the slide rod to be adjusted, which enables the support mechanism to adapt to wire harnesses of different diameters and shapes, thus improving the versatility and flexibility of the sealing structure.

[0038] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0039] This application discloses a node sealing structure for connecting wire harnesses.

[0040] Reference Figure 1 A node sealing structure for connecting wire harnesses includes a sleeve 1, a sealing layer 2 fixedly connected to the inner wall of the sleeve 1, and the sealing layer 2 providing a protective environment for the connection point 5. This protection ensures that the connection point 5 is not affected by the external environment. The node sealing structure is set at the connection of wire harness 1 3 and wire harness 2 4. The first wire harness is formed by wire harness 1 3 and the second wire harness is formed by wire harness 2 4. The connection point 5 is formed by the electrical connection of wire harness 1 3 and wire harness 2 4. An injection hole 8 is fixedly connected through the sleeve 1 and the sealing layer 2, and the injection hole 8 is located above the sleeve 1. The injection hole 8 is used to inject injection molding material.

[0041] Reference Figure 2 , Figure 3The sealing mechanism 6 is located at both ends of the inner wall of the sealing layer 2. The sealing mechanism 6 includes a support plate 61, which is fixedly connected to both ends of the sealing layer 2. The outer surface of the support plate 61 has an arc-shaped notch 1 for supporting the wire harness. One end of the connecting post 64 is fixedly connected to the middle of the support plate 61. Both ends of the auxiliary cylinder 7 are provided with sealing mechanisms 6, and both ends of the auxiliary cylinder 7 are fixedly connected to one end of the connecting post 64. The outer surface of the auxiliary cylinder 7 has an arc-shaped notch 2 for supporting the wire harness. The diameter of the auxiliary cylinder 7 is smaller than the diameter of the sealing layer 2, so that the auxiliary cylinder 7 and the sealing layer 2 are connected in a certain way. Layer 2 has a gap. Threaded hole 65 is opened on one side of connecting post 64. Threaded hole 65 is located in the middle of the side away from auxiliary cylinder 7. Threaded hole 65 is mainly used to connect support mechanism 9. Rubber ring 1 62 is fixedly connected to the outer surface of connecting post 64. Rubber ring 2 63 is fixedly connected to the outer surface of connecting post 64. Rubber ring 1 62 is located at the end away from auxiliary cylinder 7, and support plate 61 is located between rubber ring 1 62 and rubber ring 2 63. Rubber ring 1 62 and rubber ring 2 63 are inflatable rubber rings. Inflating device is set on the outer surface of sleeve 1, and inflating and deflating rubber ring 1 62 and rubber ring 2 63 are performed through the inflating device.

[0042] When sealing the nodes of the connecting wire harness, the second wire harness 4 passes through the arc-shaped notch 1 on the outer surface of the support plate 61, and then through the arc-shaped notch 2 on the outer surface of the auxiliary cylinder 7, so that the second wire harness 4 exits from the other end of the sealing layer 2, and the connection point 5 is located between the sealing mechanisms 6 set at both ends of the sealing layer 2. The first rubber ring 62 and the second rubber ring 63 absorb and disperse part of the stress, protecting the auxiliary cylinder 7 and the wire harness from damage. At the same time, the elasticity of the rubber material can also buffer vibration and impact, and improve the durability of the sealing structure.

[0043] Reference Figure 4 , Figure 5The support mechanism 9 is located inside the sealing layer 2. The support mechanism 9 includes a screw 91, with the screw 91 threaded into the threaded hole 65. A cross-shaped groove is formed on the side of the screw 91 away from the threaded hole 65, facilitating installation and disassembly of the support mechanism 9. A circular plate 92 is rotatably connected to the outer surface of the screw 91. A sliding groove 93 is circumferentially formed on one side of the circular plate 92, located on the side of the circular plate 92 away from the sealing mechanism 6. The sliding groove 93 restricts the sliding direction of the sliding rod 94, preventing it from deviating. The sliding rod 94 is slidably connected inside the sliding groove 93. An arc-shaped plate 95 is fixedly connected to one end of the sliding rod 94, located at the end away from the screw 91. The arc-shaped plate 95 is made of rubber, and its inner wall has wavy protrusions, mainly for better... The connecting wire is attached to the inner wall of the sealing layer 2. The sliding column 96 is fixedly connected to one side of the sliding rod 94. The sliding column 96 is located on the side away from the first circular plate 92. The second circular plate 97 is rotatably connected to the outer surface of the screw 91. The second circular plate 97 is located on the side away from the first circular plate 92. The arc groove 98 is circumferentially opened inside the second circular plate 97, and the sliding column 96 is slidably connected inside the arc groove 98. The arc groove 98 is used to limit the sliding direction of the sliding column 96 and prevent it from deviating. The number and position of the arc groove 98, the sliding groove 93, the sliding rod 94, the arc plate 95, the first arc notch and the second arc notch are consistent. The side of the second circular plate 97 away from the sliding rod 94 is fixedly connected to the cylinder 99, and the cylinder 99 is located on the side away from the first circular plate 92. The screw 91 is rotatably connected inside the cylinder 99.

[0044] The operator fixes the support mechanism 9 inside the sealing mechanism 6 by rotating screw 91. Then, the operator rotates the cylinder 99. The rotation of the cylinder 99 causes the circular plate 97 and the arc groove 98 to rotate together. Since the sliding column 96 is slidably connected inside the arc groove 98, the rotation of the arc groove 98 causes the sliding column 96 to expand outward. The expansion of the sliding column 96 causes the sliding rod 94 and the arc plate 95 fixedly connected to it to expand outward together. The number and position of the arc groove 98, the sliding groove 93, the sliding rod 94, the arc plate 95, the arc notch 1 and the arc notch 2 are consistent. That is, when the arc plate 95 expands outward, it will tightly adhere the wire harness 3 and the wire harness 4 placed in the arc notch 1 and the arc notch 2 to the inner wall of the sealing layer 2.

[0045] The inflation and deflation of rubber ring 62 and rubber ring 63 using an inflation device is existing technology and will not be elaborated on here.

[0046] The implementation principle of the node sealing structure for connecting wire harnesses in this application embodiment is as follows:

[0047] When in use, wire harness 2 4 is passed through the arc-shaped notch 1 on the outer surface of the support plate 61, and then through the arc-shaped notch 2 on the outer surface of the auxiliary cylinder 7, so that wire harness 2 4 is passed out from the other end of the sealing layer 2, and the connection point 5 is located between the sealing mechanisms 6 set at both ends of the sealing layer 2, so as to ensure that the connection point 5 can be completely sealed.

[0048] After the wire harness 3 is placed, the operator rotates screw 91 to fix the support mechanism 9 inside the sealing mechanism 6. Then, the operator rotates cylinder 99. The rotation of cylinder 99 causes circular plate 2 97 and arc groove 98 to rotate together. Since the sliding column 96 is slidably connected inside the arc groove 98, the arc groove 98 rotates and causes the sliding column 96 to expand outward. The expansion of the sliding column 96 causes the sliding rod 94 and arc plate 95, which are fixedly connected to it, to expand outward together. The number and position of arc groove 98, sliding groove 93, sliding rod 94, arc plate 95, arc notch 1 and arc notch 2 are consistent. That is, when the arc plate 95 expands outward, it will tightly adhere the wire harness 3 and wire harness 4 placed in arc notch 1 and arc notch 2 to the inner wall of the sealing layer 2.

[0049] Subsequently, the rubber ring 62 and rubber ring 63 are inflated by the inflation device, so that both ends of the sealing layer 2 are sealed by the rubber ring 62 and rubber ring 63. Finally, the injection molding material is injected into the interior of the sealing layer 2 through the injection hole 8 to make it completely sealed. Since the auxiliary cylinder 7 is set inside the sealing layer 2, the use of injection molding material can be reduced. After the injection molding material solidifies, the operator turns the screw 91 to remove the support mechanism 9 for the next use.

[0050] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
