Description

Technical Field

[0001] The present invention relates to the technical field of building electrical pipeline construction technology, and in particular to a prefabricated assembled electrical quick-install pipeline, a connection device and a system. Background Art

[0002] The construction market is a major pillar industry in my country, and wires and cables are a crucial component of building electrical construction. In building electrical design and construction, household electrical wiring currently utilizes protected conduit wiring. The construction process involves grooving, burying the conduit, threading the wires, and wiring. To facilitate threading, wires must be reserved for threading within the conduit during installation. The ends of the protective conduits must be polished to prevent scratching during threading. To ensure smooth threading, the conduit openings must be pre-treated, and threading and junction boxes must be installed at bends and branches in accordance with construction specifications. Specialized tools are required to connect bends and pipes during on-site construction, and wiring must be performed in accordance with electrical specifications.

[0003] The inventors have discovered that in recent years, there has been a shortage of skilled workers in my country's construction market and labor costs have increased rapidly. However, traditional and inefficient construction methods have been used for electrical terminal pipelines. These construction processes must be completed on-site, with many operating procedures, long working hours, low efficiency, large workload, high technical requirements, difficulty in maintenance and replacement, high wiring error rate, and poor assembly consistency. Summary of the Invention

[0004] As many components and parts in the building as possible are designed and prefabricated in a factory-like manner, and only assembly and connection are required at the construction site. The traditional electrical method of separating pipelines and constructing them separately is no longer suitable for the requirements of prefabricated buildings and is in urgent need of change and innovation. The mechanical and electrical equipment supporting prefabricated buildings are modularized and manufactured in a factory-like manner. They need to be assembled as quickly as possible and undergo simple post-processing at the construction site to greatly improve safety. In response to this situation, the present invention has developed a quick connection method for electrical terminal pipelines and a corresponding series of products, which integrate electrical protection tubes with electrical wires and produce them into integrated multi-variety wire pipes and connectors in the factory. During on-site construction, a quick plug-in method is used between wire pipes, and three-way or four-way connectors are used at the branches. This allows the wire pipes to be prefabricated in the factory, quickly connected on-site, and the junction box and on-site bending pipes to be eliminated, greatly simplifying the steps of wire threading and wiring during construction. It has the advantages of high product quality, simple and fast on-site construction with high efficiency, low technical requirements for construction personnel, and easy control of construction quality.

[0024] Working principle: The present invention is mainly used for the connection between the terminal pipeline laying of building electrical equipment and terminal electrical products. According to the national building electrical design specifications, the wires must be laid in pipes, but there is no requirement for the number of connectors in the middle of the high-voltage wires. It is only necessary to meet the total voltage drop specification requirements. Therefore, the present invention proposes a method to combine the wires and protective tubes in the factory on the basis of complying with existing specifications, and add plugs at both ends to form an integrated pipeline product. During specific implementation, according to the requirements of the engineering design party and on-site users, the pipelines are made into standardized and serialized products, and are quickly installed on site by plugging. Typical connection methods are shown in the attached. Figure 2 .

[0025] From the attached Figure 2 From the connection process, it can be seen that the electrical terminal pipeline starts from the distribution box and ends at the terminal electrical products switches, sockets, lamps, etc. After the line comes out from the distribution box, the electrical terminal pipeline adopts the terminal electrical connector 3, the connector at the distribution box, flexible pipeline 1, straight connector 2, three-way connector 4 to the terminal electrical connector 3 lamps, sockets, switches and other terminal electrical appliances.

[0026] Advantages of the present invention: Invented an innovative construction method for electrical terminal pipelines, which completely changed the conventional inefficient construction method of electrical terminal pipelines at the building end.

The construction procedures were numerous, the speed was slow, the quality was difficult to control, the operation efficiency was low, and the technical requirements were high. It was not suitable for the engineering prefabrication requirements required by prefabricated buildings. The characteristics of the present invention are that it fully studied the user needs and design and construction related specifications of the building electrical terminal pipelines, invented a quick connection method for electrical pipelines, integrated the pipelines into one, produced a variety of specifications and serialized wire pipes and connectors in the factory, and used a simple and fast plug-in method to carry out the construction of electrical terminal pipelines at the construction site, which simplified the construction procedures, increased the speed, made the quality easy to control, increased the operation efficiency, and reduced the technical requirements for workers.

[0027] The key technical points of the present invention are:

[0051] Example 1

[0052] The present invention proposes Figure 1 The diagram shows the series connection form and component composition of a prefabricated and assembled electrical quick-install pipeline, which includes: a flexible pipeline 1, a straight-through connector 2, an end electrical connector 3, and a three-way connector 4.

[0053] Among them, the present invention Figure 2 The figure shows the structural composition of the flexible pipeline 1, which includes: a connecting component 11 and a flexible line pipe 12. Figure 3 The schematic diagram of the structural composition of the connecting component 11 is shown, which includes: a metal terminal 111, a waterproof ring 112, a connecting component body 113, and a connecting component fastener 114. The metal terminal 111 is preferably made of copper or copper alloy, with a silver surface treatment, and can also be made of other conductive materials and surface treatments. The waterproof ring 112 is preferably made of silicone material. The connecting component body 113 is preferably made of flame-retardant PVC or PC material, and can also be made of other flame-retardant plastic materials with a softening temperature above 80-85 degrees. The connecting component fastener 114 is preferably made of flame-retardant PC or ABS or nylon or other flame-retardant and temperature-resistant plastics, and can also be other corrosion-resistant metal materials such as zinc alloy or SUS stainless steel. Figure 4 The figure shows the structure of the flexible conduit 12, which includes a flexible sleeve 121 and a cable 122. Flexible sleeve 121 is a flexible tube, preferably made of a flexible metal tube, such as galvanized steel or SUS stainless steel. It also includes a composite flexible metal tube with a flame-retardant PVC outer layer, or a flexible tube made of flame-retardant plastic or other materials. Cable 122 is preferably made of flame-retardant PVC insulation, but other insulating and flame-retardant materials are also acceptable. Figure 5 The manufacturing features of the flexible pipeline 1 are shown. Connecting component 11 and flexible pipeline 12 are first electrically connected and fastened via metal terminal 111 and cable 122. Then, flame-retardant PVC, PC, or other flame-retardant and heat-resistant plastic is injected twice into the mold to form a single unit. The first injection molding process involves pre-fixing the metal terminal 111 and cable 122, while the second injection molding process secures the flexible sleeve 121. This ensures precise positioning and structural strength between connecting component 11 and flexible pipeline 12.

[0054] Among them, the present invention Figure 6A schematic diagram of the structure of the through-connector 2 is shown, comprising a through-connector body 21, a power supply metal terminal 22, a grounding metal terminal 23, and an adapter 24. The through-connector body 21 utilizes a single-layer structure made of flame-retardant PVC or PC, but other flame-retardant and heat-resistant plastic materials with a softening temperature above 80-85°C can also be used. Alternatively, the through-connector body 21 can utilize a two-layer composite structure. The inner layer is still preferably made of flame-retardant PVC or PC, but other flame-retardant and heat-resistant plastic materials with a softening temperature above 80-85°C can also be used. The outer layer is preferably made of corrosion-resistant metal materials such as zinc alloy or SUS stainless steel, but other flame-retardant and heat-resistant plastic materials can also be used. The two layers can be fastened together through assembly and in-mold injection molding. The power supply metal terminal 22 is the actual conductive working terminal, and the grounding metal terminal 23 is the grounding terminal. Both the power supply metal terminal 22 and the grounding metal terminal 23 are preferably made of copper or a copper alloy with a silver surface treatment. Other conductive materials and surface treatments can also be used. The adapter 24 preferably uses a cable made of flame-retardant PVC insulation material, and can also use other cables with insulating flame-retardant materials or conductive metal connectors such as copper. The manufacturing feature of the straight-through connector 2 is that the power metal terminal 22 and the adapter 24 are first electrically connected and fastened, and then integrated with the straight-through connector body 21 through the in-mold injection molding process. It should be specially explained here that the reason why the power metal terminal 22 needs to be connected in the middle by the adapter 24 is mainly to ensure that during the connection process between the connecting component 2 at both ends of the male straight-through connector 2 and the connecting component 1 at both ends of the flexible pipeline 1, the connecting component 2 at any end of the straight-through connector 2 can be inserted into the connecting component 1 at any end of the flexible pipeline 1, and there will be no problem of reverse connection of the power line, thereby ensuring the consistency and correctness of the power line, and playing a role in the reliability of power safety and ease of installation.

The through-connector body 21 can also be constructed of a two-layer composite structure. The inner layer is still preferably constructed of flame-retardant PVC or PC, or other flame-retardant and heat-resistant plastic materials with a softening temperature above 80-85°C. The outer layer is preferably constructed of corrosion-resistant metal materials such as zinc alloy or SUS stainless steel, or other flame-retardant and heat-resistant plastic materials. The two layers can be fastened together through assembly and in-mold injection molding. The metal terminals 32 are preferably constructed of copper or copper alloy with a silver surface treatment, but other conductive materials and surface treatments are also acceptable. The fastening nut 33 is preferably constructed of flame-retardant PC, nylon plastic, or other flame-retardant and wear-resistant plastics, or other corrosion-resistant metal materials such as zinc alloy or SUS stainless steel. The wiring cable 34 is preferably made of flame-retardant PVC insulation material, but other flame-retardant insulation materials may also be used. The manufacturing characteristics of the terminal electrical connector 3 are that the metal terminal 32 and the wiring cable 34 are first electrically connected and fastened, and then integrated with the connector body 31 through an in-mold injection molding process.

The connecting component 1 fastener 114 of the flexible pipeline 1 is then locked with the body of the straight-through connector 2. The connection and fastening method is not limited to the threaded connection fastening method, and can also be a hook or other structural fastening method.

[0059] 3. The terminal electrical connector 3 includes a connecting component 2 in one direction, and the connecting component 2 can be inserted into the connecting component 1 11 in any direction of the flexible pipeline 1.
