Description

Technical Field

[0001] This utility model belongs to the field of building curtain wall technology, specifically relating to an anti-interference fixing device for wiring inside a building curtain wall. Background Technology

[0002] With the continuous advancement of technology, various sophisticated electronic devices and systems are increasingly widely used in the construction field, especially in the design of glass curtain walls and decorative curtain walls. These curtain walls not only require an aesthetically pleasing appearance and practical functionality, but also need to possess excellent electromagnetic shielding and anti-interference capabilities to ensure the normal operation of electronic equipment inside and around the curtain wall.

[0003] In the design of glass curtain walls or decorative curtain walls, wiring harness fixing devices are one of the key components to ensure the normal operation of electronic systems. These wiring harness fixing devices must not only be able to securely fix various cables, but also have excellent electromagnetic shielding capabilities to prevent external electromagnetic interference from affecting the equipment inside the curtain wall. At the same time, considering the long-term use of the curtain wall and the various environmental factors that may be encountered, the wiring harness fixing devices must also have excellent stability and durability.

[0004] Although existing wiring harness junction boxes usually have electromagnetic shielding, the metal liner is a two-part design, which may result in incomplete fastening or poor sealing, leading to an unsatisfactory electromagnetic shielding effect and inability to completely shield against external electromagnetic interference.

[0005] Meanwhile, existing technologies may not provide sufficient measures for securing and protecting wire harnesses, which can easily lead to loosening, damage, or electromagnetic interference. Utility Model Content

[0006] The purpose of this invention is to provide an anti-interference fixing device for wiring inside building curtain walls, in order to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an anti-interference fixing device for wiring inside a building curtain wall, including a top cover and a junction box. The top cover is adapted to the upper opening of the junction box, and the top cover and the junction box are integrally formed with corresponding ears at the four corners. The ears are provided with screw holes. When the top cover seals the upper opening of the junction box, the two can be fixedly connected by aligning the screw holes of the ears and screwing in the locking bolts.

[0008] To achieve electromagnetic shielding, a metal inner liner is embedded and fixed inside the junction box, while a metal inner cover is attached and fixed to the lower surface of the top cover. The metal inner liner has an open top structure, and the metal inner cover is adapted to the upper opening of the metal inner liner. When the top cover seals the upper opening of the junction box, the metal inner cover will also seal the upper opening of the metal inner liner. In this embodiment, the metal inner liner provides installation space for wiring harnesses. Therefore, wire holes are drilled on the front and rear surfaces of the junction box to pass through the inside of the metal inner liner. The wiring harness passes through the wire holes into the metal inner liner for wiring operations.

[0009] To ensure a more stable connection between the metal inner cover and the metal inner box forming the shielding space, downward-curving folds are provided on the left and right sides of the metal inner cover. A protrusion is integrally formed on the outer surface of the fold, while recessed grooves are provided on the left and right inner sides of the metal inner box. When the metal inner cover seals the upper opening of the metal inner box, the folds are inserted downwards into the metal inner box. During this movement, the protrusions and the metal inner box are spaced apart, facilitating the sealing between the metal inner cover and the metal inner box. After sealing, external force pushes the folds outwards, causing the protrusions to embed into the grooves, creating a snap-fit ​​state. This further locks the metal inner cover and the metal inner box together to prevent separation.

[0010] To ensure the entire junction box is sealed, a rubber plug is installed at the wire hole position for sealing. Specifically, the wire harness needs to be passed through the center hole of the rubber plug before the rubber plug is inserted into the wire hole.

[0011] In this embodiment, after the wire harness is wired inside the metal inner liner box, it can be placed in the wire groove structure for further fixation. The wire groove structure is located between two opposite wire holes and consists of two parallel, spaced-apart ribs integrally formed on the inner bottom surface of the metal inner liner box. The position between the ribs forms the wire groove. A strip-shaped pressure line is glued to the lower surface of the metal inner liner cover. The pressure line is made of soft rubber and is adapted to fit the wire groove. When the metal inner liner cover seals the upper opening of the metal inner liner box, the pressure line is correspondingly embedded into the wire groove, and the pressure line also presses the wire harness in the wire groove, thus achieving the function of pressing and fixing the wire harness.

[0012] The front and rear ends of the wire groove are spaced apart from adjacent wire holes and form insertion slots. These slots are formed by ensuring that the front and rear ends of the ribs do not contact the front and rear walls of the metal inner liner box. Based on these slots, it can be inferred that most of the wire harnesses inside the metal inner liner box are embedded in the wire groove, while the wire harnesses near the wire holes and located at the insertion slots are not constrained by the ribs. Based on this structural feature, and considering that the protrusions require external force to be inserted into the grooves, a dial wheel push rod structure is provided on the side of the insertion slot near the folded edge. This dial wheel push rod structure includes a sliding guide seat, a sliding member, and a dial wheel. The wheel axle and sliding guide seat are integrally formed on the inner bottom surface of the metal inner liner box. The inner side of the sliding guide seat is provided with guide holes extending laterally to the left and right. The sliding member is inserted into the guide hole, so the sliding member can actually slide laterally to the left and right. It can be seen that when the sliding member slides a certain distance towards the insertion port, the sliding member can push the wire harness at this point to the side, so that this part of the wire harness is not collinear with the wire harness in the wire groove. This bending design can better disperse and resist tensile force when the wire harness is subjected to external force, reducing the risk of wire harness breakage or damage.

[0013] As a further aspect of the present invention: the axle is arranged in a front-to-back direction, with its front and rear ends penetrating the metal inner liner box and the wire box. The axle is rotatably connected to both the metal inner liner box and the wire box. Each sliding member is connected to an adjacent folded edge by a dial wheel, which has a central hole and is fixedly mounted on the axle. The dial wheel has an elliptical structure, with its two ends used to contact the folded edge and the sliding member, respectively. By rotating the axle, the dial wheel rotates, at which point the lower end of the dial wheel pushes the sliding member to bend the wire harness, while the upper end of the dial wheel pushes the folded edge, causing the protrusion to embed into the groove. This structural design not only improves the tensile strength of the wire harness but also enhances the shielding effect, thus preventing the metal inner liner cover from separating from the metal inner liner box due to external force.

[0014] As a further aspect of the present invention: In order to lock the rotation of the axle, a gear is fixedly fitted on the end of the axle. The gear is located on the outside of the wire box. The gear drives and meshes with an adjusting screw. The rotation of the adjusting screw causes the gear to rotate, which in turn causes the axle to rotate. A screw sleeve that matches the adjusting screw is integrally formed on the outer surface of the wire box. The adjusting screw is screwed into the screw sleeve and passes through the screw sleeve.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model,

[0016] (1) It is mainly composed of a top cover and a wire box. It is fixedly connected by ears, screw holes and locking bolts. A metal inner liner box is embedded and fixed inside the wire box, while a metal inner liner cover is attached and fixed on the lower surface of the top cover. When the top cover covers the wire box, the metal inner liner cover will also cover the metal inner liner box, thus forming a shielding space.

[0017] (2) The wire harness is inserted into the metal inner box through the wire hole for wiring. After the wiring is completed, the wire harness can be placed in the wire groove structure to further fix the wire harness. At the same time, the pressure line will press the wire harness in the wire groove to fix the wire harness.

[0018] (3) The metal inner liner cover and the metal inner liner box are connected by a snap-fit ​​through a folded edge and a snap-fit ​​groove to ensure the stability of the shielding space. At the same time, the presence of the protrusion can further improve the stability of the connection.

[0019] (4) The pulley push rod structure can bend the wire harness when subjected to external force to better disperse and resist tensile force, reduce the risk of wire harness breakage or damage. At the same time, this bending design can also improve the shielding effect and prevent the metal inner cover from separating from the metal inner box due to external force.

[0020] (5) By rotating the adjusting screw, the wheel axle can be driven to rotate, thereby controlling the working state of the dial push rod structure. At the same time, the design of the gear and screw sleeve can lock the rotation of the wheel axle, ensuring the stability of the device during operation. Attached Figure Description

Detailed Implementation

[0028] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-5 The present invention provides a technical solution: an anti-interference fixing device for wiring inside a building curtain wall, comprising an upper cover 1 and a junction box 2. The upper cover 1 is adapted to the upper opening of the junction box 2, and the upper cover 1 and the junction box 2 are integrally formed with corresponding ears at the four corners, and screw holes 15 are provided on the ears. When the upper cover 1 covers the upper opening of the junction box 2, the two can be fixedly connected by aligning the screw holes 15 of the ears and screwing in the locking bolts.

[0030] To achieve electromagnetic shielding, a metal inner liner box 4 is embedded and fixed inside the wire box 2, while a metal inner liner cover 3 is attached and fixed to the lower surface of the upper cover 1. The metal inner liner box 4 has an open structure at the top, and the metal inner liner cover 3 is adapted to the upper opening of the metal inner liner box 4. When the upper cover 1 seals the upper opening of the wire box 2, the metal inner liner cover 3 will also seal the upper opening of the metal inner liner box 4. In this embodiment, the metal inner liner box 4 provides installation space for wire harness wiring. Therefore, wire holes 7 are drilled on the front and rear surfaces of the wire box 2 to the inside of the metal inner liner box 4. The wire harness passes through the wire holes 7 into the metal inner liner box 4 for wiring operations.

[0031] To make the connection between the metal inner cover 3 and the metal inner box 4 more stable, downward-curved folds are provided on the left and right sides of the metal inner cover 3. A protrusion 13 is integrally formed on the outer surface of the fold, while a recessed snap groove 14 is provided on the left and right inner sides of the metal inner box 4. When the metal inner cover 3 seals the upper opening of the metal inner box 4, the fold is inserted downward into the metal inner box 4. During this movement, the protrusion 13 and the metal inner box 4 are spaced apart to facilitate the sealing between the metal inner cover 3 and the metal inner box 4. After sealing, the fold is pushed outward by external force to make the protrusion 13 embed into the snap groove 14. At this time, a snap-fit ​​state is formed, and the metal inner cover 3 and the metal inner box 4 can be further locked to prevent separation.

[0032] To ensure the sealing of the entire junction box 2, a rubber plug 19 is installed at the wire hole 7 for sealing. Specifically, the wire harness needs to be passed through the center hole of the rubber plug 19 and then the rubber plug 19 is inserted into the wire hole 7.

[0033] In this embodiment, after the wire harness is wired inside the metal inner box 4, it can be placed in the wire groove 6 to further fix the wire harness. The wire groove 6 is located between two wire holes 7 that are directly opposite each other. The wire groove 6 is composed of two parallel and spaced ribs 5, which are integrally formed on the inner bottom surface of the metal inner box 4. At this time, the position between the ribs 5 forms the wire groove 6. A strip-shaped pressure line 8 is glued to the lower surface of the metal inner cover 3. The pressure line 8 is made of soft rubber material and is adapted to the wire groove 6. When the metal inner cover 3 seals the upper opening of the metal inner box 4, the pressure line 8 is correspondingly embedded into the wire groove 6. The pressure line 8 also presses the wire harness in the wire groove 6, thus achieving the function of pressing and fixing the wire harness.

[0034] The front and rear ends of the wire groove 6 are spaced apart from the adjacent wire holes 7, forming insertion slots 20. These slots 20 are formed by ensuring that the front and rear ends of the rib 5 do not contact the front and rear walls of the metal inner liner box 4. Based on these slots 20, it can be seen that most of the wire harnesses inside the metal inner liner box 4 are embedded in the wire groove 6, while the wire harnesses near the wire holes 7 and located at the insertion slots 20 are not constrained by the rib 5. Based on this structural feature, and considering that the protrusion 13 requires external force to be inserted into the latching groove 14, a dial push rod structure is provided on the side of the insertion slot 20 near the folded edge. This dial push rod structure includes a sliding guide seat 9 and a sliding member 10. The dial 11, the axle 12, and the sliding guide seat 9 are integrally formed on the inner bottom surface of the metal inner liner box 4. The inner side of the sliding guide seat 9 is provided with guide holes that extend laterally to the left and right. The slider 10 is inserted into the guide hole, so the slider 10 can actually slide laterally to the left and right. It can be seen that when the slider 10 slides a certain distance toward the insertion port 20, the slider 10 can push the wire harness at this point to the side, so that this part of the wire harness is not collinear with the wire harness in the wire groove 6. This bending design can better disperse and resist tensile force when the wire harness is subjected to external force, reducing the risk of wire harness breakage or damage.

[0035] The axle 12 is arranged in a front-to-back direction, with its front and rear ends passing through the metal inner liner box 4 and the wire box 2. The axle 12 is rotatably connected to both the metal inner liner box 4 and the wire box 2. Each sliding member 10 is connected to an adjacent folded edge by a dial wheel 11. The dial wheel 11 has a central hole and is fixedly mounted on the axle 12. The dial wheel 11 has an elliptical structure, with its two ends used to contact the folded edge and the sliding member 10, respectively. By rotating the axle 12, the dial wheel 11 rotates. At this time, the lower end of the dial wheel 11 pushes the sliding member 10 to bend the wire harness, while the upper end of the dial wheel 11 pushes the folded edge, causing the protrusion 13 to be embedded in the buckle groove 14. This structural design not only improves the tensile strength of the wire harness but also enhances the shielding effect, thus preventing the metal inner liner cover 3 from separating from the metal inner liner box 4 due to external forces.

[0036] To lock the rotation of the axle 12, a gear 18 is fixedly fitted on the end of the axle 12. The gear 18 is located on the outside of the junction box 2. The gear 18 drives and meshes with an adjusting screw 16. The rotation of the adjusting screw 16 causes the gear 18 to rotate, which in turn causes the axle 12 to rotate. A screw sleeve 17 that matches the adjusting screw 16 is integrally formed on the outer surface of the junction box 2. The adjusting screw 16 is screwed into the screw sleeve 17 and passes through it.
