Description

Technical Field

[0001] This utility model belongs to the field of building electrical installation technology, specifically relating to a decorative electrical junction box for plum blossom drilling, which is used to solve the problems of low installation efficiency and poor positioning accuracy caused by the mismatch between existing pre-embedded junction boxes and plum blossom drilling. Background Technology

[0002] In the construction of modern building electrical systems, the wiring of various electrical devices requires the use of pre-embedded junction boxes to ensure standardization and safety. While staggered drilling, as a specific drilling method, offers advantages in improving the stability and aesthetics of wall structures, the development of compatible pre-embedded junction boxes is crucial for perfecting the building electrical installation process. However, existing pre-embedded junction boxes, when used in conjunction with staggered drilling, reveal several problems that urgently need to be addressed.

[0003] 1. Poor installation compatibility: Most existing pre-embedded junction boxes are conventionally square or round, which are severely mismatched with the unique plum blossom-shaped outline of the plum blossom drill hole. This makes it difficult for the pre-embedded junction box to be smoothly inserted into the plum blossom drill hole during installation. Installers often need to spend a lot of time making additional adjustments to the drill hole or junction box, which greatly reduces construction efficiency.

[0004] 2. Insufficient Positioning Accuracy: The lack of a reliable positioning mechanism is another drawback of existing pre-embedded junction boxes. After installation, irregularly shaped pre-embedded junction boxes are prone to displacement due to construction operations such as concrete pouring and vibration. This not only affects the smoothness of subsequent wire laying in conduits but may also lead to positional deviations during the installation of electrical equipment, preventing proper connection and ultimately affecting the stability and functionality of the entire electrical system.

[0005] Therefore, adapting the plum blossom-shaped electrical and plum blossom-shaped electrical boxes for installation on secondary structures such as masonry and partition walls with special shapes can help improve construction quality, optimize processes, shorten construction time, and reduce costs. To this end, this utility model provides a pre-embedded box with plum blossom-shaped drilling. Utility Model Content

[0006] The technical problem solved by this utility model is to provide a decorative electrical junction box specifically for plum blossom drilling. The purpose of this utility model is to solve the problems of low installation efficiency and poor positioning accuracy caused by the mismatch between existing pre-embedded junction boxes and plum blossom drilling.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] Decorative electrical junction boxes with perforated patterns, including:

[0009] The plum blossom-shaped embedded outer box consists of an embedded shell, mounting hole A, and a slot;

[0010] The plum blossom-shaped inner box consists of a battery core board, mounting hole B, outer copper sheet limiting groove, inner copper sheet limiting groove, pin copper sheet limiting groove, copper sheet mounting hole, cable inlet and panel clip.

[0011] The plum blossom-shaped decorative cover consists of a decorative panel, a pin hole, and a panel slot;

[0012] The pre-embedded housing has a positioning protrusion groove on its outer side, which is used to cooperate with the groove on the inner wall of the plum blossom drill hole;

[0013] The battery cell board is shaped like a plum blossom, with its edges fitting against the inner sidewall of the pre-embedded housing, and is detachably connected to the pre-embedded housing through mounting hole B and copper sheet mounting hole;

[0014] The decorative panel is connected to the pre-embedded housing via a panel slot, and the decorative panel has a plum blossom-shaped pin hole.

[0015] Further defining the above scheme, the embedded housing is integrally injection molded from high-strength engineering plastic; the groove height of the embedded housing is 5-8mm, the width is 3-5mm, and the fit tolerance with the inner wall groove of the plum blossom drill hole is controlled within ±0.5mm.

[0016] Further defining the above scheme, the battery cell board is made of epoxy glass cloth laminate FR-4, which has multiple standard mounting holes B, and the hole spacing is designed according to the general mounting dimensions of electrical components.

[0017] Further specifying the above solution, the outer copper sheet limiting groove, the inner copper sheet limiting groove, and the pin copper sheet limiting groove are made of brass and are embedded in the battery cell board through injection molding.

[0018] Further defining the above scheme, the inlet is located below the battery cell board and is used for threading wires and connecting to the outer copper sheet limiting groove, the inner copper sheet limiting groove and the pin copper sheet limiting groove for power supply.

[0019] Further specifying the above solution, the decorative panel has five pin holes with a diameter of 8-12mm.

[0020] Further defining the above solution, the panel slot is made of high-strength plastic material and is integrally formed with the embedded shell and decorative panel.

[0021] Advantages of this utility model compared to the prior art:

[0022] 1. Improved installation convenience: The perfect fit between the box and the Phillips head hole makes the installation process simple and efficient; installers can quickly complete the installation without additional adjustments to the drill holes or the junction box. At the same time, it optimizes the problem of wire collision between different plugs during the wiring process of traditional junction boxes, significantly shortens the installation time of a single junction box, and greatly improves the overall construction efficiency.

[0023] 2. Guaranteed Positioning Accuracy: The cooperation between the positioning protrusions and grooves provides a stable and reliable positioning method for the embedded junction boxes. During construction processes such as concrete pouring, the embedded junction boxes can maintain their precise position, effectively avoiding displacement. This provides a solid foundation for subsequent wire laying and electrical equipment installation, greatly improving construction quality and reducing the risk of rework.

[0024] 3. Enhanced protective sealing: The slot design at the cable hole in the cover plate forms an excellent waterproof and dustproof barrier. Under simulated rain spray conditions, no water ingress was observed inside the box; in dusty environment simulation tests, the amount of dust accumulation inside the box was reduced by more than 90% compared to boxes without sealing rings, effectively extending the service life of wires and electrical equipment.

[0025] 4. This solution has good versatility: the standard hole positions are compatible with a variety of electrical components and have a wide range of applications. Attached Figure Description
