Description

Technical Field

[0001] This application belongs to the field of connector technology, specifically relating to a connector shield and an electrical device. Background Technology

[0002] Most high-voltage through-connectors are suitable for single-core cables and have a shield crimp only on the outer cable braid, using an assembly method where the outer plastic shell assembly mates with the shield crimp.

[0003] However, conventional high-voltage through-connectors cannot reliably secure multi-core cables. Utility Model Content

[0004] The purpose of this utility model is to provide a shielding component for a connector, which aims to overcome the technical problem that current connectors do not provide sufficient fixing level for multi-core cables; another purpose of this application is to provide an electrical device.

[0005] Technical solution: This application discloses a shielding component for a connector, comprising:

[0006] The main body has a receiving cavity for housing the main wire of the cable, and the main body is fixedly connected to the main wire.

[0007] Multiple branch tubes are arranged on one side of the main body. Each branch tube has a wire-passing channel. The receiving cavity is connected to the wire-passing channel. The wire-passing channel is used to sleeve the strands of the cable. The branch tube is fixedly connected to the strands of the cable.

[0008] This application also discloses an electrical device, including:

[0009] The housing has an assembly hole, and the outer wall of the housing has a protruding mounting tube with an installation channel that communicates with the assembly hole.

[0010] The shield of the connector as described in the above embodiments passes through the mounting channel and is partially located within the receiving cavity, and is fixedly connected to the housing.

[0011] Beneficial Effects: The connector shielding disclosed in this application includes a main body and multiple branch tubes. The main body has a receiving cavity for housing the main wire of the cable, and the main body is fixedly connected to the main wire. Multiple branch tubes are arranged on one side of the main body, each branch tube having a wire-passing channel. The receiving cavity communicates with the wire-passing channel, which is used to house the cable strands. The branch tubes are fixedly connected to the cable strands. The main body and branch tubes of the shielding can comprehensively enclose the main wire and strands of the cable, effectively preventing the leakage of electromagnetic signals generated by the internal current transmission of the cable. It also prevents external electromagnetic interference from affecting the signal transmission stability within the cable, improving signal transmission quality and anti-interference capability. The fixed connection between the main body and the main wire, and the fixed connection between the branch tubes and the strands, not only ensures the positional stability of each part of the cable in complex operating environments, avoiding damage caused by shaking or pulling, but also protects the cable to a certain extent and extends its service life. The separate design of the branch conduit and the main body allows for easy cable installation. Each strand can be threaded into its corresponding branch conduit before the main cable is inserted into the receiving cavity of the main body. This simplifies the process. During later maintenance, if a problem occurs with a single strand, only the branch conduit containing that strand needs to be inspected, eliminating the need to replace the entire cable and reducing maintenance costs.

[0012] The electrical equipment in this application includes a shielding component for the connector as described in the above embodiments, and therefore can possess all the technical features and effects of the aforementioned shielding component, which will not be repeated here. Furthermore, this application uses an integrally formed mounting tube on the housing of the electrical equipment to install the shielding component and fix it to the housing. This solution eliminates the need for an outer plastic shell assembly, resulting in a high degree of integration, fewer parts, and reduced manufacturing costs. Attached Figure Description

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] In the description of this application, it should be understood that the terms "upper," "lower," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. In the description of this application, "multiple" means two or more, and at least one can mean one, two, or more, unless otherwise explicitly specified.

[0026] As a preamble to the embodiments of this application, most high-voltage through-connectors are suitable for single-core cables and only have shielding crimping on the outer cable braid layer, using an assembly method where the outer plastic shell assembly mates with the shielding crimping. However, for multi-core cables, conventional high-voltage through-connectors cannot reliably fix multi-core cables. For example, if the cable has no fixing structure, axial displacement occurs, resulting in poor torsional resistance. Furthermore, existing outer plastic shell assemblies have high manufacturing costs, low integration levels, and affect the assembly efficiency with the shell. At the same time, the internal structural support of multi-core cables is unstable, the assembly stability between the shielding assembly and the cable is poor, the single strand has no fixing structure, and the seismic resistance is insufficient.

[0027] In view of this, embodiments of this application provide a shielding component for a connector, which aims to solve at least one of the above-mentioned technical problems.

[0028] Please see Figure 1 As shown in the figure, this application discloses a connector shield 1, including: a body portion 11 and a plurality of branch tubes 12. The body portion 11 has a receiving cavity 110 for housing the main wire 21 of the cable, and the body portion 11 is fixedly connected to the main wire 21. The plurality of branch tubes 12 are arranged on one side of the body portion 11, and each branch tube 12 has a wire passage 120. The receiving cavity 110 communicates with the wire passage 120, and the wire passage 120 is used to housing the strands 22 of the cable. The branch tubes 12 are fixedly connected to the strands 22 of the cable. It should be understood that the cable of this application is a multi-core cable with one main wire 21 and multiple strands 22. The body portion 11 and the branch tubes 12 of the shield 1 can fully wrap the main wire 21 and the strands 22 of the cable, effectively blocking the leakage of electromagnetic signals generated by the internal current transmission of the cable. At the same time, it can also prevent external electromagnetic interference from affecting the signal transmission stability inside the cable, thereby improving the signal transmission quality and anti-interference capability. It is also important to understand that the main body 11 is fixedly connected to the main line 21, and the branch pipe 12 is fixedly connected to the strand 22. This not only ensures the positional stability of each part of the cable in complex operating environments and avoids damage to the line due to shaking, pulling, etc., but also protects the cable to a certain extent and extends its service life.

[0029] In some embodiments, both the main body 11 and the branch pipe 12 are made of a metal material with high magnetic permeability, such as a soft magnetic alloy. This material can greatly enhance the shielding effect and effectively reduce electromagnetic interference.

[0030] In some embodiments, anti-slip rubber pads (not shown in the figure) are provided on the inner wall of the receiving cavity 110 of the main body 11 and the inner wall of the wire passage 120 of the branch pipe 12. When the main wire 21 and the strand wire 22 are respectively inserted, the rubber pads increase the friction and achieve a tight fixation. At the same time, fastening bolts are provided on the main body 11 and the branch pipe 12 respectively to further ensure a stable connection with the cable.

[0031] In some embodiments, a transition chamfer is provided at the connection between the branch pipe 12 and the main body 11, so that the strand 22 can enter the receiving cavity 110 more smoothly from the branch pipe 12, avoiding damage to the line due to stress concentration.

[0032] In some embodiments, the main body 11 and the branch pipe 12 are made of copper alloy.

[0033] In some embodiments, an adhesive layer (not shown) is provided inside the main body 11 and the branch conduit 12. When the cable is inserted, the adhesive layer cures, achieving a firm connection with the cable. At the same time, a clamp is provided on the outside of the main body 11 to enhance the fixing effect on the main line 21.

[0034] In some embodiments, the body 11 is interference-fitted with the main cable 21, and the branch pipe 12 is interference-fitted with the cable strands 22. It should be understood that this application uses interference fits to connect the body 11 to the main cable 21 and the branch pipe 12 to the strands 22, eliminating the need for additional connecting parts, greatly simplifying the assembly process, shortening installation time, effectively improving production efficiency, and reducing labor costs. The pressure generated by the interference fit ensures a tight fit between the shield 1 and the cable. The rigidity of the shield 1 protects the internal structure of the cable from damage, improving the cable's mechanical protection performance. The tight interference fit effectively reduces air gaps between the shield 1 and the cable, reducing impedance mismatch during signal transmission, thereby reducing signal reflection and attenuation. The tight connection formed by the interference fit effectively prevents external moisture and dust from entering the shield 1 and contacting the cable. In humid and dusty environments, it prevents the cable from short-circuiting or corroding due to moisture, ensuring long-term stable operation and extending the cable's service life.

[0035] Please see Figure 1 As shown, in some embodiments, the cross-sectional area of ​​the threading channel 120 is smaller than the cross-sectional area of ​​the receiving cavity 110. It should be understood that the cross-sectional area of ​​the main wire 21 is greater than the sum of the cross-sectional areas of the strands 22; correspondingly, the cross-sectional area of ​​the receiving cavity 110 is greater than the sum of the cross-sectional areas of the threading channel 120. Simultaneously, a gap 13 needs to be reserved between adjacent branch tubes 12. This gap 13 prevents the branch tubes 12 from being squeezed and deformed due to excessively dense arrangement, ensuring the integrity of the branch tube 12's own structure. When the shielding component 1 is subjected to external impact or vibration, the gap 13 can buffer stress, prevent mutual interference between the branch tubes 12, maintain the stability of the entire shielding component 1 structure, and thus ensure effective protection and fixation of the cable strands 22. During current transmission, the cable generates heat, which is concentrated within the branch tubes 12. The existence of the gap 13 provides space for heat dissipation. Air can circulate in the gap 13, carrying away the heat generated by the strands 22, preventing heat accumulation that could lead to excessively high cable temperatures, affecting the cable's performance and service life.

[0036] Please see Figure 1 As shown, in some embodiments, both the main body 11 and the branch pipe 12 are tubular structures, and the outer surfaces of both the main body 11 and the branch pipe 12 are formed with extrusion marks 111. It should be understood that by setting the extrusion marks 111, the friction between the main body 11 and the main wire 21, and the friction between the branch pipe 12 and the strand wire 22, is increased, thus achieving a fixed connection between the shield 1 and the cable. Simultaneously, it makes it easier to fix the shield 1, significantly increasing the friction between the shield 1 and external contact objects, effectively preventing the shield 1 from sliding and ensuring stability. Furthermore, during the process of forming the extrusion marks 111, the internal structure of the material changes, resulting in work hardening, which improves the strength and hardness of the tubular structure. This not only enhances the shield 1's ability to resist external forces but also effectively protects the internal cable, making it less susceptible to damage to the integrity of the internal cable when subjected to external impacts or compression, and improving stress relaxation within the cable.

[0037] Please see Figure 1 As shown, in some embodiments, the outer surface of the body portion 11 is also formed with an extrusion groove 112. It should be understood that the portion where the main cable 21 connects to the body portion 11 (the main cable 21 connector) is extruded to form a positioning groove, which is used to position and fix the body portion 11 and the main cable 21, reducing assembly difficulty. When the shielding component 1 is subjected to external forces such as bending, tension, or compression, the extrusion groove 112 can act as a buffer area for stress concentration points, allowing stress to diffuse along the direction of the groove, preventing excessive stress concentration at a single point that could lead to cracking or damage to the body portion 11, thereby enhancing the structural strength and deformation resistance of the body portion 11.

[0038] It should be understood that the connector of the main line 21 is a conventional design, including multiple strand conductors and filler inside, a shield braid that wraps the filler and strand conductors, and the outermost main line sheath. By turning the shield braid outward and fixing a metal sleeve between the turned-out shield braid and the main line sheath, the metal sleeve can increase the structural strength of the connector of the main line 21, and at the same time facilitate the cooperation with the shielding component to achieve fixed assembly.

[0039] Please see Figures 2 to 9As shown, this application also discloses an electrical device, which is a device requiring shielding performance, such as a distribution box. The electrical device includes: a housing 3 and a shielding member 1 with a connector as described in the above embodiment; the housing 3 has an assembly hole 30, and an installation tube 31 protrudes from the outer wall of the housing 3, the installation tube 31 having an installation channel 310, the installation channel 310 communicating with the assembly hole 30; the shielding member 1 passes through the installation channel 310 and is partially located within the receiving cavity 110, and is fixedly connected to the housing 3. It should be understood that the housing 3 of the electrical device has a receiving cavity, in which electronic devices are arranged, and the housing 3 in the figures of this application is only for illustration. The assembly hole 30 on the housing 3 and the installation tube 31 protruding from the outer wall provide precise installation position guidance for the shielding member 1. The installation channel 310 of the installation tube 31 communicates with the assembly hole 30, allowing the shielding member 1 to be smoothly inserted. During the installation process, the operator can quickly and accurately place the shielding member 1 in the predetermined position, greatly improving installation efficiency and reducing installation errors caused by inaccurate positioning. The shielding component 1 passes through the installation channel 310 and is partially located within the receiving cavity 110, and is fixedly connected to the housing 3, ensuring a stable connection between the shielding component 1 and the electrical equipment housing 3. This connection method not only ensures that the shielding component 1 will not loosen due to vibration, shaking, or other factors during the operation of the electrical equipment, but also provides a reliable physical basis for the electrical connection. The installation tube 31 cleverly utilizes the outer wall space of the electrical equipment housing 3. The installation position of the shielding component 1 avoids occupying too much space inside the electrical equipment, allowing the internal space of the electrical equipment to be used more effectively for arranging electrical components and wiring, thus optimizing the overall spatial layout.

[0040] Meanwhile, this application uses an integrally formed mounting tube 31 on the housing 3 of the electrical equipment to install the shielding component 1, and at the same time fixes the shielding component 1 to the housing 3. The above solution omits the outer plastic shell assembly, has a high degree of integration, fewer parts, and reduced manufacturing costs.

[0041] In some embodiments, the method of fixing the shielding component 1 to the housing 3 includes: setting positioning pins and positioning holes (not shown in the figure) at corresponding positions on the inner wall of the housing 3 and the outer wall of the shielding component 1. When the shielding component 1 passes through the mounting channel 310 and partially enters the interior of the housing 3, the positioning pins cooperate with the positioning holes to further ensure the accurate installation position of the shielding component 1, while enhancing the connection stability between the shielding component 1 and the mounting tube 31. The method of fixing the shielding component 1 to the housing 3 also includes: designing a snap-fit ​​structure (not shown in the figure) at the contact point between the shielding component 1 and the housing 3. After the shielding component 1 is inserted into place, by pressing or rotating, the snap-fit ​​is tightly engaged with the slot on the housing 3 to achieve quick and secure fixing. This method is not only easy to operate, but also allows for easy release of the fixing when the shielding component 1 needs to be disassembled for maintenance or replacement, improving the convenience of maintenance.

[0042] In some embodiments, a sealing gasket (not shown) is provided at the connection between the mounting tube 31 and the shield 1. The sealing gasket can be made of a material with good elasticity and sealing performance, such as rubber, to fill the gap between the two and effectively prevent dust, moisture, and other impurities from entering the electrical equipment. At the same time, the sealing gasket also acts as a buffer, reducing friction and wear between the shield 1 and the mounting tube 31 caused by vibration.

[0043] In some embodiments, after the shielding member 1 is fixed to the housing 3, sealant (not shown in the figure) is applied to the joint between the two to further enhance the sealing effect. The sealant can fill tiny gaps to form a complete sealing layer, improving the protection level of the electrical equipment, and is especially suitable for electrical equipment used in harsh environments such as humid and dusty conditions.

[0044] In some embodiments, heat dissipation fins (not shown) are installed on the outer surface of the shielding component 1 or the outer wall of the mounting tube 31. The heat dissipation fins increase the heat dissipation area and improve heat dissipation efficiency. The heat dissipation fins can be made of a metal material with good thermal conductivity, such as aluminum alloy, and are fixedly connected to the shielding component 1 or the mounting tube 31 by welding or riveting, effectively transferring heat to the surrounding air.

[0045] Please see Figures 2 to 5 , Figures 7 to 9 As shown, in some embodiments, the electrical equipment further includes a cable clamp assembly 4, disposed within the housing 3. The cable clamp assembly 4 includes clamping pieces 41, which form a limiting space 410. The branch pipe 12 is partially housed within the limiting space 410, and the clamping pieces 41 are fixedly connected to the housing 3. It should be understood that by using the limiting space 410 formed by the clamping pieces 41 to fix and limit the branch pipe 12, and then by fixing the clamping pieces 41 to the housing 3, the cable can be effectively fixed and positioned to resist stress caused by pulling or twisting the cable. This fixing method is simple to operate and easy to install, effectively improving the stability of the cable.

[0046] Please see Figure 9 As shown, in some embodiments, the wire clamp assembly 4 further includes a connector 42, such as a screw or a locating pin, wherein the housing 3 has a locating hole (e.g., Figure 6 As shown, the clip 41 is fixedly connected to the housing 3 by screws or positioning pins engaging with positioning holes, thereby fixing the shield 1.

[0047] Please see Figure 1 , Figure 7 and Figure 8As shown, in some embodiments, a gap 13 is provided between adjacent branch pipes 12, and the clip 41 has a spacer portion 411, which at least partially protrudes within the gap 13 and is connected to the branch pipe 12. It should be understood that the spacer portion 411 protruding within the gap 13 and connected to the branch pipe 12 acts like a "bridge" between adjacent branch pipes 12, providing additional support for the branch pipes 12. This allows the branch pipes 12 to work together to resist external forces, such as vibration, tension, or compression, when the entire shielding component 1 is subjected to external forces, reducing the possibility of deformation or damage to the branch pipes 12 due to individual stress. This significantly enhances the overall structural stability of the shielding component 1 and effectively prevents the branch pipes 12 from loosening or shifting. When the shielding component 1 is subjected to external forces, the spacer portion 411 can distribute the stress to the adjacent branch pipes 12. Since the spacer 411 is connected to the branch pipe 12, the stress is no longer concentrated on a single branch pipe 12, but is transmitted and dispersed among multiple branch pipes 12 through the spacer 411. This avoids excessive local stress that could cause the branch pipe 12 to crack or be damaged, and further improves the reliability and durability of the structure.

[0048] Please see Figures 2 to 6 As shown, in some embodiments, the electrical equipment further includes a seal 5 and a cover 6. The seal 5 is disposed within the installation channel 310 and sleeved on the main line 21, and is connected to the side of the body 11 away from the branch pipe 12. The cover 6 is sleeved on the outer periphery of the main line 21 and is sealed to both the main line 21 and the installation pipe 31 to seal the installation channel 310. It should be understood that the seal 5, sleeved on the main line 21 and connected to the side of the body 11 away from the branch pipe 12, fills the gap between the installation channel 310 and the main line 21, effectively preventing external impurities such as dust, moisture, and oil from entering the electrical equipment through the gap between the main line 21 and the installation channel 310, protecting the electrical components inside the equipment from contamination and corrosion, and extending their service life. The seal 5 has a certain degree of elasticity, which can act as a buffer between the main line 21 and the installation channel 310. When electrical equipment is subjected to vibration or impact, the seal 5 can absorb some energy, reducing the friction and collision between the main line 21 and the inner wall of the installation channel 310 caused by vibration, protecting the outer sheath of the main line 21 from wear, and thus avoiding electrical faults caused by sheath damage, improving the reliability of the cable in dynamic environments. The cover 6 provides an additional physical protective barrier for the electrical equipment. It can prevent larger objects from directly entering the installation channel 310, preventing these objects from damaging the internal shield 1, main line 21, and other components. The cover 6 also works in conjunction with the seal 5 to further improve the overall sealing performance of the electrical equipment. The design of the cover 6 also facilitates maintenance or repair of the internal parts of the electrical equipment, improving the convenience of maintenance and repair, and reducing maintenance time and costs.

[0049] Please see Figures 2 to 6 As shown, in some embodiments, the inner wall of the housing 3 is provided with a mounting base 32, which partially blocks the assembly hole 30, and the main body 11 abuts against the mounting base 32. It should be understood that the partial blocking of the assembly hole 30 by the mounting base 32 provides a clear positioning reference for the main body 11 of the shielding component 1. Since the mounting base 32 is pre-set on the inner wall of the housing 3, the shielding component 1 only needs to pass through the mounting channel 310 and abut against the mounting base 32 to initially complete its positioning, followed by subsequent fixing operations. Simultaneously, the abutment between the main body 11 and the mounting base 32 reduces the relative displacement between the shielding component 1 and the housing 3, enhancing connection stability and avoiding problems such as loose electrical connections and unstable signal transmission caused by shaking. The abutment method between the mounting base 32 and the main body 11 of the shielding component 1 allows the cable to be routed orderly along the space formed by the mounting base 32 and the shielding component 1 when entering the housing 3. This not only facilitates the wiring operation but also makes the cable routing more regular, facilitating subsequent cable organization and bundling. Neat wiring helps improve the heat dissipation efficiency inside electrical equipment, and also facilitates later maintenance and repair work. Staff can more clearly distinguish each cable and quickly locate and solve problems.

[0050] Please see Figures 5 to 6 as well as Figure 9 As shown, in some embodiments, the shielding component 1 is fixedly connected to the mounting base 32, and the mounting base 32 is provided with a protrusion 321, which protrudes between two adjacent branch pipes 12. It should be understood that the fixed connection between the shielding component 1 and the mounting base 32 ensures that the position of the shielding component 1 within the electrical equipment remains stable and will not easily shift or loosen due to external forces, thus guaranteeing the reliability of the connection between the cable and the electrical equipment. When the shielding component 1 receives external forces such as tension or torque from the cable, the mounting base 32 and the shielding component 1 work together to distribute the external force onto the housing 3, reducing the stress on the shielding component 1 itself, lowering the risk of damage to the shielding component 1, and further enhancing the stability and durability of the entire structure. By providing the protrusion 321, which contacts the branch pipe 12 and is located between two adjacent branch pipes 12, more precise positioning of the branch pipe 12 is achieved. Simultaneously, the fixing force on the branch pipe 12 is increased, limiting its swaying and displacement, further ensuring the stability of the internal strands 22. Furthermore, the protrusion 321 on the mounting base 32 and the spacer 411 on the clamp 41 effectively fix and support the branch pipe 12, while simultaneously enabling rapid positioning and installation, improving installation convenience and efficiency.
