Description

Technical Field

[0001] The utility model belongs to the field of electrical technology and relates to a quick connection of electric wires, in particular to a quick connection connector for an electric line. Background Art

[0002] In modern life, people increasingly demand greater convenience and speed in the installation and maintenance of electrical equipment. For example, in home renovations, electricians need to quickly connect wiring to shorten construction timelines and minimize disruption to residents' lives. In industrial production, if electrical equipment on an assembly line fails, quick-connect connectors can quickly repair it, reducing downtime and improving production efficiency. Quick-connect connectors allow non-professional users to easily connect electrical wiring in simple scenarios, such as connecting wires when replacing a light fixture.

[0003] However, the current common devices have insufficient number of connectors, low resistance system efficiency, inconvenient installation and easy damage. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art and provides an electrical circuit quick connection connector.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An electrical circuit quick-connect joint comprises an insulating shell; insulating circuit interfaces are symmetrically provided at both ends of the insulating shell; and two electrical wiring units with the same structure are symmetrically provided between the insulating circuit interfaces at both ends of the insulating shell.

[0007] The electrical wiring unit includes a press cover, an elastic bent copper sheet, an annular isolator, and a bottom support block; the bottom support block is fixed to the bottom of the insulating shell and is located on the inner side of the insulating line interface, the root of the elastic bent copper sheet is fixed to the bottom of the insulating shell, and its front is located above the bottom support block, and the line connector is inserted between the bottom support block and the front of the elastic bent copper sheet; the fixed end of the press cover is hinged to the middle part of the insulating shell through a rotating shaft, and the movable end of the press cover extends out of the insulating shell and is located above the insulating line interface; when the press cover is pressed down, it drives the elastic bent copper sheet to move downward and squeeze the line connector.

[0008] A rotating shaft is provided on the top of the insulating line interface, and a buckle is fixedly connected to the top of the rotating shaft; when the cover plate is pressed down into place, the buckle acts on the movable end of the cover plate.

[0009] Further preferably, an annular isolator is fixed in the middle of the elastic bent copper sheet, a guide cylinder is fixed on the annular isolator, a limiting sleeve cooperating with the guide cylinder is provided on the bottom surface of the cover plate, and a spring is assembled between the guide cylinder and the limiting sleeve.

[0010] During operation, the two wire connectors (copper wires) to be connected are inserted through the sealing rings into the insulated wiring connections at each end of the connector. The connection is then established through the two electrical connection units within the insulated housing. The wiring connections are located between the front of the elastically bent copper sheet and the bottom support block. By pressing down on the movable end of the press cover, which rotates about the fixed end, downward pressure is applied directly to the elastically bent copper sheet, or by a spring-driven annular spacer and the elastically bent copper sheet moving downward, causing the front of the elastically bent copper sheet to contact and squeeze the wiring connections, establishing good contact. After the press cover is pressed into place, the rotating shaft is rotated, and the movable end of the press cover is secured with a snap to maintain good electrical contact. This ensures electrical connection between the wiring at both ends of the connector through the elastically bent copper sheet within. This ensures good contact between the two wires, reducing connection resistance, minimizing energy loss, and improving the efficiency of the electrical system. The installation process is also simple and quick, requiring no complex tools or specialized skills, significantly improving work efficiency.

[0011] Further preferably, the roots of the two elastically bent copper sheets in the two electrical wiring units are connected as one piece, so that the circuits at both ends of the joint can be well electrically connected.

[0012] Further preferably, a limiting block is fixed above the root of the elastically bent copper sheet, and the limiting block can be used to prevent the root of the elastically bent copper sheet from being displaced when the front portion is subjected to downward pressure.

[0013] Further preferably, a vertical partition is fixedly provided in the middle of the insulating shell above the limit block; and the two vertical partitions in the two electrical wiring units are adjacently and oppositely arranged.

[0014] Further preferably, a positioning block is provided at the end of the bottom support block, and the positioning block is used to limit the displacement of the bottom support block when it is in frictional contact with the line connector and the front part of the elastic bent copper sheet.

[0015] Further preferably, a limit cover is provided in the middle of the insulating shell behind the push cover. After the push cover is reset, it abuts against the limit cover to limit the reset of the push cover, thereby preventing the limit sleeve at the bottom of the push cover from detaching from the cylinder on the annular isolation piece.

[0016] Further preferably, a protective cover is provided on the front of the insulating shell below the cover plate to provide protection and aesthetics.

[0017] Further preferably, the movable end of the push cover is provided with a snap block, which cooperates with the snap to limit the position of the push cover after it is pressed down, thereby ensuring the normal operation of the electrical wiring unit.

[0018] Further preferably, a sealing ring is provided on the outer port of the insulating line interface to protect the line connection.

[0019] Further preferably, a plug-in block is provided on one side of the insulating shell and a corresponding plug-in slot is provided on the other side; in this way, multiple blocks can be connected in parallel, and multiple lines can be connected simultaneously by splicing.

[0020] Working principle: First confirm the number of wires that need to be connected. This device can realize the simultaneous connection of multiple lines by splicing. Just align the plug-in blocks and plug-in slots on both sides of the insulating shell and insert them. It is convenient and quick. Then insert the wires to be connected into the insulating line interface through the sealing ring. Then it can be successfully connected through the electrical wiring unit. The protective cover and the limit cover protect the electrical wiring unit to work normally. The wires are inserted into the insulating line interface through the sealing ring and then enter the inside of the insulating shell. The copper wire in the wire is placed below the two ends of the elastic bent copper sheet and above the bottom support block. Then press the cover plate. The cover plate sinks around the rotating axis to drive the limit sleeve to compress the spring, pushing the annular isolation piece downward. The front part of the elastic bent copper sheet contacts and squeezes the copper wire, and is close to the top of the bottom support block, thereby realizing line connection. The limit block prevents the root of the elastic bent copper sheet from displacing when it is subjected to pressure from above. The positioning block limits the displacement of the bottom support block when it is in friction contact with the copper wire and the elastic bent copper sheet. Finally, by twisting the rotating shaft, the buckle is buckled on the buckle plate of the press cover plate, so that the electrical wiring unit is in working state, and the two lines at both ends of the joint are reliably connected.

[0021] Compared with the prior art, the electrical circuit quick connect connector described in the present invention has the following beneficial technical effects:

[0022] First, the electrical circuit quick connection connector can achieve simultaneous connection of multiple lines by splicing according to the number of wire lines that need to be connected. The plug-in blocks and plug-in slots on both sides of the insulating shell can be aligned and inserted to achieve modular combination, which is convenient and fast. Then, the wire connector to be connected (usually copper wire) is inserted into the insulating line interface through the sealing ring. As a result, the installation process becomes very simple and quick, without the need for complex tools and professional skills, which greatly improves work efficiency.

[0023] Second, the electrical circuit quick connection connector can be successfully connected through the electrical wiring unit. The protective cover and the limit cover protect the electrical wiring unit to work normally; turn the buckle to fix the electrical wiring unit, thereby ensuring good contact between the wires, thereby reducing connection resistance, reducing power loss, and improving the efficiency of the electrical system.

[0024] Third, the electrical circuit quick connection connector is inserted into the insulating circuit interface through the sealing ring through the wire and then enters the inside of the insulating shell. The copper wire ends of the two wires to be connected are respectively placed under the elastic bent copper sheets at both ends and above the bottom support block (generally a copper block is selected). Then the cover plate is pressed, and the cover plate rotates and sinks to drive the limit sleeve to compress the spring, pushing the annular isolation piece downward, and the elastic bent copper sheet contacts and squeezes the copper wire, tightly against the top of the bottom support block, thereby realizing the connection of the lines on both sides. The limit block prevents the root of the elastic bent copper sheet from being displaced when it is subjected to upper pressure, and the positioning block limits the displacement of the bottom support block when it is in frictional contact with the copper wire and the elastic bent copper sheet. Finally, by screwing the rotating shaft, the buckle is buckled on the buckle plate at the movable end of the cover plate. As a result, there is no need to use open flames and welding equipment, which reduces the safety risks and operation difficulty during installation, and also avoids connection quality problems caused by poor welding.

[0025] The utility model has reasonable design and modular design, can be assembled in parallel at will, has simple structure, is easy to operate, and has good practical application value. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," and "disposed" should be understood in a broad sense. For example, they may refer to fixed connection or disposition, detachable connection or disposition, or integral connection or disposition. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0037] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0038] A quick-connect connector for electrical wiring, such as Figure 1 、 Figure 2 、 Figure 3 As shown, the device comprises an insulating housing 8; insulating line interfaces 1 are symmetrically provided at both ends of the insulating housing 8; and sealing rings 7 are provided on the outer ends of the insulating line interfaces 1. Two identical electrical wiring units 4 are symmetrically provided between the insulating line interfaces 1 at both ends of the insulating housing 8. Two plug-in blocks 6 are provided on one side of the insulating housing 8, and two corresponding plug-in slots 9 are provided on the other side. Adjacent insulating housings 8 can be connected in parallel via the plug-in blocks 6 and plug-in slots 9, enabling parallel assembly and multi-line electrical connection.

[0039] like Figure 4 、5 As shown, the electrical wiring unit 4 comprises a cover plate 401, a resiliently bent copper sheet 406, an annular spacer 407, and a bottom support block 405 (typically a copper block). The bottom support block 405 is fixed to the bottom of the insulating housing 8, inside the insulated line interface 1. A retaining block 409 is provided at the end of the bottom support block 405. The bases of the two resiliently bent copper sheets 406 in the two electrical wiring units 4 are integrally connected, electrically connected. The base of the resiliently bent copper sheet 406 is fixed to the bottom of the insulating housing 8, with its front portion positioned above the bottom support block 405. A line connector (typically a copper wire) is inserted between the bottom support block 405 and the front portion of the resiliently bent copper sheet 406. A limit block 408 is fixed above the base of the elastically bent copper sheet 406 and can be fixedly connected to the insulating housing 8. A vertical partition 403 is fixedly installed in the middle of the insulating housing 8, above the limit block 408, and can be fixedly connected to the insulating housing 8. The two vertical partitions 403 in the two electrical connection units 4 are arranged adjacent to each other. The fixed end of the press cover 401 is hinged to the middle of the insulating housing 8 via a rotating shaft 412. The rotating shaft 412 can be fixedly connected to the insulating housing 8, and the press cover 401 rotates around the rotating shaft 412. The movable end of the press cover 401 extends outside the insulating housing 8 and is located above the insulated line interface 1. An annular spacer 407 is fixed to the middle of the elastically bent copper sheet 406. A guide cylinder 411 is fixed to the annular spacer 407. A limiting sleeve 402 is provided on the bottom surface of the press cover 401, which cooperates with the guide cylinder 411. A spring 410 is installed between the guide cylinder 411 and the limiting sleeve 402. When the press cover 401 is pressed down, the spring 410 in the limiting sleeve 402 is compressed, transmitting the pressure to the annular spacer 407, and driving the elastically bent copper sheet 406 downward, so that the front of the elastically bent copper sheet 406 contacts and squeezes the copper wire. A rotating shaft 2 is provided at the top of the insulated line interface 1, and a buckle 3 is fixedly connected to the top of the rotating shaft 2. When the press cover 401 is pressed down into place, a buckle block 404 is provided at the movable end of the press cover 401. The buckle 3 acts on the buckle block 404 at the movable end of the press cover 401, locking the press cover 401. A protective cover 5 is provided at the front of the insulating shell 8 below the pressing cover 401 ; a limiting cover 10 is provided at the middle of the insulating shell 8 behind the pressing cover 401 , and the pressing cover 401 abuts against the limiting cover 10 after being reset.

[0040] During specific operation, the two wire connectors (copper wires) that need to be connected are respectively inserted into the insulated line interfaces 1 at both ends of the connector through the sealing ring 7, and then the connection is successfully made through the two electrical wiring units 4 in the insulating shell 8. The line connector is located between the front of the elastically bent copper sheet 406 and the bottom support block 405. After pressing down the movable end of the cover plate 401 to rotate it around the fixed end, the downward pressure drives the annular isolator 407 and the elastically bent copper sheet 406 downward through the spring 410 (or the guide cylinder 411), so that the front of the elastically bent copper sheet 406 contacts and squeezes the line connector to form a good contact; in this process, the guide cylinder 411 does not need to participate in the transmission of force. Under normal circumstances, there is a certain distance between the guide cylinder 411 and the bottom surface of the limit sleeve 402. This stroke is the compression of the spring 410. During the stroke, spring 410 drives annular spacer 407 downward, forcing elastically bent copper sheet 406 downward. Of course, after spring 410 is compressed, guide cylinder 411 can also contact the bottom surface of stop sleeve 402, ultimately applying pressure to annular spacer 407 through guide cylinder 411. This is also possible. The use of spring 410 here ensures flexible force transmission. Of course, the spring can also be omitted, achieving rigid contact between press cover 401 and elastically bent copper sheet 406, with the rigid force transmission driving the downward movement of elastically bent copper sheet 406. After press cover 401 is pressed into place, rotating shaft 2 is rotated and buckle 3 is used to limit the movable end of press cover 401 to maintain good electrical contact. The wires at both ends of the connector are now electrically connected through the elastically bent copper sheet 406 within. This ensures good contact between the two wires, thereby reducing connection resistance, minimizing power loss, and improving the efficiency of the electrical system. The installation process is also very simple and quick, requiring no complex tools or specialized skills, greatly improving work efficiency.

[0041] In specific application, the wire is inserted into the insulating line interface 1 from the sealing ring 7 and then enters the inside of the insulating shell 8. The copper wire in the wire is placed below the two ends of the elastic bent copper sheet 406 and above the bottom support block 405. Then the cover plate 401 is pressed, and the cover plate 401 sinks to drive the rotating shaft 412 and the limit sleeve 402, compressing the spring 410, pushing the annular isolation piece 407 downward, and the elastic bent copper sheet 406 contacts and squeezes the copper wire, tightly against the top of the bottom support block 405, thereby realizing line connection. The limit block 408 prevents the elastic bent copper sheet 406 from displacing when subjected to upper pressure, and the positioning block 409 limits the bottom support block 405 from displacing when it frictionally contacts the copper wire and the elastic bent copper sheet 406. Finally, by twisting the rotating shaft 2, the buckle 3 is buckled on the buckle plate 404. In this way, there is no need to use open flames and welding equipment, which reduces the safety risks and operation difficulty during installation, and also avoids connection quality problems caused by poor welding.

[0042] The above description is only a preferred specific implementation method of the present invention. The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology, but the protection scope of the present invention is not limited to this. Any technician familiar with this technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
