The construction procedures are as follows: slotting, pipe burying, threading, wiring, etc. In order to facilitate threading in the pipe, a threading iron wire must be reserved in the pipe during pipe laying, and the end of the protection pipe must be polished to prevent scratching the wire during threading. In order to make threading smooth, the pipe opening must be pretreated, and threading boxes and wiring boxes must be set at the turning and branching points according to the construction specifications. Special tools are needed for pipe bending and pipe connection in the field, and wiring must be done according to the electrician's specifications.

[0003] In order to realize quick connection with prefabricated building electrical quick-mount pipeline and improve the efficiency of field electrical wiring construction, a matching connector is quickly assembled through the application of an assembled prefabricated quick-mount pipeline.

[0025] The embodiment discloses a prefabricated building electrical quick-mount pipeline connector, which comprises Figures 1 to 6As shown, the device can comprise: a distributor assembly 10 and a wiring assembly 20, the distributor assembly 10 comprising a distributor shell 11 and an electric connection unit 12, a conductive unit 13 arranged in the distributor shell 11 and connected in sequence, the electric connection unit 12 and the conductive unit 13 arranged in a distributor base body 15; the wiring assembly 20 comprising a group of electric wires 21, a protective tube 22, a wire clamping unit 24 and a connecting shell 23, the group of electric wires 21 capable of extending into the connecting shell 23 through a second end of the connecting shell 23, the protective tube 22 sleeved outside the group of electric wires 21 and fixedly connected to the second end of the connecting shell 23, the group of electric wires 21 comprising three electric wires 21, the wire clamping unit 24 capable of being fixed in the connecting shell 23 and fixing the electric wires 21 respectively, the electric wires 21 extending out of the second end of the connecting shell 23 and connected to the conductive unit 13, the connecting shell 23 capable of being connected to the distributor shell 11; the wire clamping unit 24 is in a cylindrical shape and capable of being fixed in the connecting shell 23, the wire clamping unit 24 comprising a upper wire clamping unit 241 and a lower wire clamping unit 242 matched with each other, the upper wire clamping unit 241 being provided with a plurality of first arc-shaped grooves 2411, the lower wire clamping unit 242 being provided with a plurality of second arc-shaped grooves 2422, the first arc-shaped grooves 2411 and the second arc-shaped grooves 2422 corresponding to each other and spliced into fixing holes at the intersection surface of the upper wire clamping unit 241 and the lower wire clamping unit 242, the fixing holes being arranged at intervals, and the fixing holes capable of clamping the electric wires 21 respectively.

[0026] In the above technical solution, the wire clamping unit 24 is arranged to separate the wires before the wires 21 extend out of the port of the wiring assembly 20, and the neutral wire, the live wire and the ground wire of the wires 21 are fixed respectively, which facilitates the connection and installation of the wires 21 and the wire splitter, and if the wires 21 are pulled, the wire clamping unit 24 can strengthen the fixation of the wires 21, which can prevent the wires not connected to the wire splitter assembly 10 from being pulled back during construction, and can also share the function of fixing the wires of the wire splitter assembly 10 after the wire splitter assembly 10 is installed, preventing the wires from being accidentally loosened. In addition, the wire clamping unit 24 is composed of the upper wire clamping unit 241 and the lower wire clamping unit 242, which form a clamping action on the wires 21, and after being clamped tightly, the connection housing 23 is installed, which can limit the radial separation and movement of the upper wire clamping unit 241 and the lower wire clamping unit 242, and the wires 21 are difficult to loosen without structural damage. The structure facilitates installation on the construction site, and the wire clamping unit 24 can be fixed in the connection housing 23, so that it can be stably kept in the installation position before being connected to the wire splitter assembly 10, which facilitates construction. For the case of using a cable including multiple wires, the wire splitter assembly 10 can be directly connected to the multiple wires 21 in the cable, so that the free and unfixed wires between the wire splitter assembly 10 and the wiring assembly 20 are shorter, which reduces the length of the device on the one hand, and on the other hand, the shorter free wires 21 make the device more compact and easier to install. Even if one of the wires 21 loosens, the other wires are still fixed by the wire clamping unit, so the cable and the wiring assembly 20 will not be disconnected, and the fixation is more stable.

[0027] It should be noted that the wire splitter housing 11 and the connection housing 23 can be connected by a suitable quick connection method, such as threaded connection, pin connection, plug connection, etc. In order to achieve the effect of waterproof and dustproof, a sealing ring or the like can be provided at the connection port to prevent water and dust from entering. In the wire splitter assembly 10, the wire splitter housing 11 is used to protect the internal structure and make the entire product a whole, and the electrical connection unit 12 can be used to connect to the electrical appliances, which can be a metal pin, a metal pin slot or the like structure to adaptively complete the connection. As a plug, a metal pin is usually used as an implementation, and as a socket, it can be a metal pin slot. Specifically, as shown in Figure 5As shown, the electrical connection unit 12 is a metal pin groove. The conductive unit 13 is used to connect and fix the wire 21, and is electrically connected to the electrical connection unit 12 so that the wire 21 group can be connected to the electrical connection unit 12. The splitter base 15 plays a supporting and fixing role, and it can be composed of rubber, plastic, or a composite of multiple insulating materials. The splitter base 15, electrical connection unit 12, and conductive unit 13 can be integrally formed by injection molding, rubber coating, etc. The protective tube 22 can be a fixed tube or a flexible metal tube, etc., and the appropriate implementation method can be selected according to the construction design requirements. The main function of the protective tube 22 is to provide protection for the internal cables. The protective tube 22 can be sealed and fixedly connected to the connecting housing 23.

[0028] The upper wire clamp 241 and lower wire clamp 242 can be of any suitable shape, as long as they can be assembled into a cylindrical shape and fixed inside the connecting housing 23. Fixing can be achieved using bolts or other fasteners, or a step can be provided inside the connecting housing 23 for fixed support. Specifically, the diameter of the wire clamp unit 24 is larger, while the diameter of the end near the protective tube 22 is smaller, forming a step. After installation, the clamp unit can abut against the step structure for fixation. The step structure also facilitates the installation and removal of the clamp unit. After the wire 21 passes through and is fixed to the clamp unit, the insulation sleeve at its end can be peeled off, facilitating connection to the splitter assembly 10. In terms of design, the diameter of the fixing hole formed by the first arc-shaped groove 2411 and the second arc-shaped groove 2422 can be smaller than the diameter of the wire 21, allowing the outer insulation sleeve of the wire 21 to elastically deform, thereby clamping the wire 21.

[0029] As a specific implementation method, such as Figure 3 , 4 As shown, the upper wire clip 241 includes a semi-cylindrical first base 2412, with a first connecting groove 2413 in the middle of the first base 2412. First arc-shaped grooves 2411 are respectively disposed at the bottom of the first connecting groove 2413 and at both ends of the opening of the first connecting groove 2413. The lower wire clip 242 includes a semi-cylindrical second base 2421, with two spaced second connecting grooves 2423. The common sidewall between the two second connecting grooves 2423 forms a first protrusion 2424. The second arc-shaped grooves 2422 are respectively disposed at the bottom of the second connecting grooves 2423 and on the side of the first protrusion 2424 facing the upper wire clip 241. The two sidewalls of the first connecting groove 2413 can respectively extend into the two second connecting grooves 2423, and the first protrusion 2424 can extend into the first connecting groove 2413.

[0030] Through the above structure, the fixing holes are evenly distributed in a ring shape on the wire clamping unit 24, ensuring insulation and stable installation, and reducing the number of components, making installation convenient. The insertion of each other prevents relative rotation, that is, the first connecting groove 2413 can cooperate with the first protruding part 2424, and the second connecting groove 2423 cooperates with the side wall of the first connecting groove 2413, thereby forming multiple limiting positions.

[0031] In order to further clamp the wire 21 and prevent it from being separated, as shown in Figure 4 The first protruding structure 2414 is arranged in the first arc-shaped groove 2411, and the second protruding structure 2425 is arranged in the second arc-shaped groove 2422. The first protruding structure 2414 and the second protruding structure 2425 are arranged in the axial direction of the fixing hole. The staggered arrangement of the first protruding structure 2414 and the second protruding structure 2425 makes the wire 21 in the fixing hole have a wave shape or an S shape, making the installation more stable, and also compressing the outer protective layer of the wire 21 to increase the deformation and improve the stability of the installation.

[0032] In order to further clamp the wire 21 and prevent the upper wire clamping unit 241 and the lower wire clamping unit 242 from being separated, as shown in Figure 4 The side wall of the first connecting groove 2413 is provided with a sawtooth-shaped first clamping structure 2415, and the outer side wall of the second connecting groove 2423 is provided with a second clamping structure 2426. The second clamping structure 2426 and the first clamping structure 2415 can be engaged with each other. Since the upper wire clamping unit 241 and the lower wire clamping unit 242 can be made of engineering plastics and other materials, they have a certain elasticity. The first clamping structure 2415 and the second clamping structure 2426 can be slightly elastically deformed during installation, and the first clamping structure 2415 and the second clamping structure 2426 can be engaged one by one by pushing, thereby forming a limiting position. By adjusting the position of the engaged teeth, the wire of different diameters can be adapted.

[0033] Further, the first clamping structure 2415 and the second clamping structure 2426 can be sawtooth-shaped structures, and the sawteeth of the sawtooth-shaped structures are slightly inclined to extend away from the joint surface of the upper wire clamping unit 241 and the lower wire clamping unit 242, so that they are easier to install but more difficult to disassemble, thereby making the connection stable.

[0034] Further, in order to guide the first clamping structure 2415 and the second clamping structure 2426 to accurately engage, as shown in Figure 4As shown, the outer side of the sidewall of the first connecting groove 2413 is further provided with a guide plate 2416, and the inner side of the outer sidewall of the second connecting groove 2423 is further provided with a guide groove 2427 matched with the guide plate 2416, and the guide groove 2427 is arranged at the middle part of the second clamping structure 2426. In addition, guide structures can be further formed at the two ends of the first clamping interface in the radial direction, for guiding the movement of the second clamping structure 2426 and limiting its deviation in the radial direction, so that the upper and lower clamping wire buckles 241 and 242 can be accurately combined to the appropriate position, and the end faces are flush.

[0035] As a specific embodiment, as shown in Figure 2 、 Figure 5 and Figure 6 , the first end of the conductive unit 13 is connected with the electrical connection unit 12, the conductive unit 13 includes a plurality of conductive pieces, the second end of the conductive piece is used to connect and fix the core of the electric wire 21, and the conductive piece includes an upper elastic sheet 131 and a lower elastic sheet 132 made of elastic metal material, and at the second end of the conductive piece, the lower elastic sheet 132 is provided with an abutting portion 1321 which gradually approaches and abuts against the upper elastic sheet 131 in the insertion direction of the core. Through the arrangement of the abutting portion 1321, the upper side thereof has a movement trend towards the upper elastic sheet 131, and when the core of the electric wire 21 is inserted, it can push the core to keep the core pressed and fitted between the abutting portion 1321 and the upper elastic sheet 131, thereby ensuring stable electrical connection and fixation of the core and preventing it from loosening. In addition, one end of the upper elastic sheet 131 for fixing the core can be provided with a groove consistent with the extension direction of the core, so that the core can partially fall into the groove and prevent the core from sliding out laterally.

[0036] In order to meet the use requirements of the line splitter, the line splitter shell 11 can be made of metal material, but the shell made of metal material needs to be able to be grounded according to relevant regulations and safety needs, so as to prevent electric leakage from causing personnel to be mistaken, therefore, as shown in Figure 5 、 Figure 6 , the electric wire 21 includes a ground wire, the line splitter shell 11 is made of metal material, and the line splitter assembly 10 further includes a ground wire elastic sheet 14, and the ground wire elastic sheet 14 is connected with the ground wire among the conductive pieces, and the ground wire elastic sheet 14 includes a fixed side 141 and an abutting side 142, the fixed side 141 is connected with the ground wire elastic sheet 14, and the abutting side 142 can pass through the line splitter base body 15 and abut against the inner sidewall of the line splitter shell 11.

[0037] In the above scheme, the ground wire is provided by means of the power supply wire 21, the splitter shell 11 is indirectly connected to the ground wire through the ground spring 14, thereby achieving the effect of grounding the splitter shell 11. On this basis, if the connecting shell 23 is also made of metal material, it can also achieve the effect of grounding when it is connected to the splitter shell 11. Further, if the protective tube 22 is also made of metal material, it can also be indirectly connected to the splitter shell 11 through the connecting shell 23 and achieve grounding, so that the exposed metal shell parts in the entire device can achieve the effect of grounding, simplifying the grounding structure. Specifically, the fixed side 141 and the abutting side 142 can have a V-shaped structure. After the fixed side 141 is fixed, the abutting side 142 naturally extends obliquely to the splitter shell 11. When installing, the connecting part of the fixed side 141 and the abutting side 142 is directed towards the opening of the splitter shell 11, and it is naturally pushed in to complete the installation, thereby simplifying the installation process.

[0038] In order to further clamp the ground wire, as shown in Figure 6 The ground spring 14 is fixed to the upper spring 131 and can push the upper spring 131 close to the lower spring 132. By fixing the ground spring 14 to the upper spring 131, when it abuts against the splitter shell 11, the resulting reaction force can further push the upper spring 131 to bend slightly downward and close to the lower spring 132, so that the upper spring 131 changes from passive abutment to active downward elastic force, thereby further clamping the ground wire.

[0039] In order to facilitate the installation of the power wire 21, as shown in Figure 5 The splitter unit further includes a knob 16, which includes a pushing part 161 and a driving part 162. The lower side of the pushing part 161 abuts against the middle part of the abutting part 1321 of the lower spring 132, and the upper part of the pushing part 161 can abut against the splitter base 15 under the driving of the lower spring 132, and the driving part 162 is exposed outside the splitter base 15. In the natural state, the knob 16 abuts against the splitter base 15 under the action of the lower spring 132 and does not play a role. When it is necessary to install or disassemble the power wire 21, the lower spring 132 can be pushed down by pushing the knob 16, so that the lower spring 132 is separated from the upper spring 131, thereby facilitating the disassembly and assembly of the power wire 21.

[0040] In order to prevent the knob 16 from pushing the lower spring 132 in an accidental situation, causing the battery to fall off, as shown in Figure 5As shown, the wire distributor unit further comprises a clamping cover 17 capable of being clamped between the wire clamping buckle unit 24 and the wire distributor base 15, and the outer peripheral edge of the clamping cover 17 is capable of abutting against the radially inner side of the driving portion 162. By virtue of the arrangement of the clamping cover 17, the downward movement of the knob 16 is limited, and the battery cell is prevented from falling off. In use, the clamping cover 17 itself can be provided with wire holes through which the power lines 21 pass, and the three power lines 21 can be passed through the wire holes in advance. After the power lines 21 are installed in place, the clamping cover 17 is clamped to the predetermined position, thereby limiting the knob 16 and preventing it from falling off.

[0041] Those skilled in the art can understand that the above-mentioned embodiments are specific cases for implementing the present disclosure, and in actual applications, various changes can be made in form and details without departing from the scope of the present disclosure.
