Description

Technical Field

[0001] This utility model relates to the field of electrical installation technology, and in particular to a wire connection device for electrical installation engineering. Background Technology

[0002] In the field of electrical installation engineering, cable connection is a crucial step in ensuring the normal operation of electrical systems. With the continuous expansion of power systems and the increasing complexity of electrical equipment, the accuracy and efficiency of cable connection work are becoming increasingly important. Currently, commonly used cable connecters achieve electrical connections primarily by tightening cables with bolts, a method that can, to some extent, guarantee the stability of the cable connection.

[0003] However, in actual operation, this wire pairing device has significant technical flaws. During pairing, operators need to insert the wires into different pairing holes and then secure them by tightening bolts. However, due to the lack of a specific fixing structure, the branch wires inside the wires are very prone to detaching from the terminals during the tightening process. Once a branch wire detaches, the installer can only re-fix it one branch at a time, which not only greatly prolongs the pairing time and reduces work efficiency but also increases labor costs and the probability of errors. Furthermore, repeated branch fixing operations may damage the wires and terminals, affecting the reliability of the electrical connection and the overall performance of the electrical system.

[0004] Therefore, it is necessary to provide a wire connection device for electrical installation engineering to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a wire pairing device for electrical installation engineering, which solves the problem that, due to the lack of a specific fixing structure, the branch wires in the wires are very easy to fall off from the terminals during the tightening of bolts.

[0006] To solve the above-mentioned technical problems, this utility model provides a wiring connector for electrical installation engineering, comprising: a connector, a fixing post, an outer ring sleeve, and a locking ring. Two fixing posts are provided, symmetrically arranged on both sides of the connector. The outer ring sleeve is located outside the fixing posts and is threadedly connected to the connector for fixation. The locking ring is threadedly connected to the outer ring sleeve and located on the side of the outer ring sleeve away from the connector. A limiting groove is formed inside the fixing post, and a limiting ball is provided inside the limiting groove. A sliding sleeve is located outside the limiting groove, and a limiting ramp is formed on the inner surface of the sliding sleeve. The thickness of the limiting ramp gradually increases as it approaches the connector. The limiting ball is located between the limiting ramp and the limiting groove. When the sliding sleeve moves away from the connector, the limiting ramp presses the limiting ball into the limiting groove. The sliding groove is formed on the outer surface of the fixing post at the end away from the connector, and the sliding sleeve is slidably connected inside the sliding groove.

[0007] Preferably, a guide sleeve is fixedly connected to the side of the sliding sleeve away from the connector, and the sliding sleeve is slidably connected to the inside of the sliding groove through the guide sleeve. An elastic block is provided on the outer surface of the guide sleeve, and a slot adapted to the elastic block is opened on the outer surface of the fixed column. A spring is provided between the guide sleeve and the sliding groove, and a guide block is fixedly connected to the outer surface of the guide sleeve.

[0008] Preferably, the fixed column has two branch holes inside, which are symmetrically arranged on the front and rear sides inside the fixed column. The limiting groove is opened on the inner surface of the branch hole near the outside. An electrical connecting plate is fixedly connected to one end of the branch hole near the connector.

[0009] Preferably, a waterproof ring is provided between the connector and the outer ring sleeve to ensure a tight connection between the fixing post and the connector. A waterproof ring is provided between the outer ring sleeve and the locking ring to seal the inlet of the locking ring cable bus.

[0010] Preferably, the outer surface of the outer ring is provided with several anti-slip grooves, which can increase the friction between the hand and the outer ring when rotating the outer ring.

[0011] Preferably, a locking assembly is provided at one end of the fixed post near the connector. The locking assembly includes two locking holes and a locking bolt. The two locking holes are opened at the top of the fixed post and are respectively connected to two branch holes. The locking bolt is threaded into the inside of the locking holes.

[0012] Compared with related technologies, the wiring device for electrical installation engineering provided by this utility model has the following advantages:

[0013] The fixed post has a limiting groove and a limiting ball inside. The sliding sleeve is located outside the limiting groove, and a limiting ramp is formed on its inner surface. After the branch line enters the fixed post, as the sliding sleeve moves away from the connector, the limiting ramp presses the limiting ball into the limiting groove. The limiting ball applies pressure to the branch line, achieving initial fixation. This prevents the branch line from detaching from the terminal during subsequent operations such as tightening bolts. Installers do not need to re-fix the branch line, significantly reducing alignment time and improving work efficiency. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figures 1 to 4 A wiring harness for electrical installation includes: a connector 100, a fixing post 200, an outer ring sleeve 400, a locking ring 600, a sliding sleeve 700, and a locking assembly 800. Two fixing posts 200 are provided, symmetrically arranged on both sides of the connector 100. The outer ring sleeve 400 is disposed outside the fixing post 200 and is threadedly connected to the connector 100 for fixation. The locking ring 600 is threadedly connected to the outer ring sleeve 400 and located on the side of the outer ring sleeve 400 away from the connector 100. The locking assembly 800... The 00 is set on the fixed post 200 and located at the end of the fixed post 200 near the connector 100. The sliding sleeve 700 is set in the middle of the outer surface of the fixed post 200. The main cable enters the inner part of the outer ring sleeve 400 from the locking ring 600, and the branch line enters the fixed post 200. Before locking with the locking assembly 800, the sliding sleeve 700 is used to initially fix the branch line, which can prevent the branch line from falling off when tightening the bolt. The installer does not need to spend a lot of time re-fixing the branch line, thus greatly shortening the wiring time.

[0021] The fixed post 200 has a limiting groove 702 inside, and a limiting ball 701 is disposed inside the limiting groove 702. The sliding sleeve 700 is located outside the limiting groove 702, and a limiting ramp 703 is formed on the inner surface of the sliding sleeve 700. The limiting ramp 703 is thicker as it gets closer to the connector 100. The limiting ball 701 is located between the limiting ramp 703 and the limiting groove 702. The sliding groove 704 is formed on the outer surface of the fixed post 200 at the end away from the connector 100. A guide sleeve 705 is fixedly connected to the side of the sliding sleeve 700 away from the connector 100, and the sliding sleeve 700 is slidably connected to the sliding groove 704 through the guide sleeve 705. An elastic block 706 is provided on the outer surface of the guide sleeve 705, and a slot 707 adapted to the elastic block 706 is formed on the outer surface of the fixed post 200. A spring 708 is provided between the guide sleeve 705 and the sliding groove 704. A guide block 709 is fixedly connected to the outer surface of the guide sleeve 705. Before the branch line enters the fixed post 200, the spring 708 pushes the sliding sleeve 700 to bring it closer to the connector 100. After the branch line enters the fixed post 200, the sliding sleeve 700 moves away from the connector 100. The sliding sleeve 700 slides inside the sliding groove 704. The limiting ball 701 starts to roll on the limiting ramp 703. Since the limiting ramp 703 is closer to the connector 100 and has a greater thickness, the limiting ball 701 is pressed into the limiting groove 702. The ball of the limiting ball 701 applies pressure to the branch line. At this time, the guide sleeve 705 enters the sliding groove 704. The guide block 709 is used to limit the movement direction of the sliding sleeve 700. The elastic locking block 706 is engaged in the locking groove 707 for fixation.

[0022] refer to Figure 1 The fixed post 200 has two branch holes 201 inside. The branch holes 201 are symmetrically arranged on the front and rear sides inside the fixed post 200. The limiting groove 702 is opened on the inner surface of the branch hole 201 near the outside. The end of the branch hole 201 near the connector 100 is fixedly connected to the electrical connection plate 202. When the branch wire enters the branch hole 201, the end of the branch wire contacts the electrical connection plate 202, completing the branching and connection of the cable.

[0023] A waterproof ring 300 is provided between the connector 100 and the outer ring 400, and a waterproof ring 500 is provided between the outer ring 400 and the locking ring 600. The waterproof ring 500 is used to seal the inlet of the cable bus of the locking ring 600, and the waterproof ring 300 is used to ensure that the connection between the fixing post 200 and the connector 100 is tight, so as to ensure that moisture does not enter the wiring point inside the outer ring 400 and keep the inside dry.

[0024] The outer surface of the outer ring sleeve 400 is provided with several anti-slip grooves 401, which can increase the friction between the hand and the outer ring sleeve 400 when rotating the outer ring sleeve 400, making it easier to screw the outer ring sleeve 400 onto the connector 100 and the locking ring 600 onto the outer ring sleeve 400.

[0025] refer to Figure 2 , Figure 3 A locking assembly 800 is provided at one end of the fixed post 200 near the connector 100. The locking assembly 800 includes two locking holes 801 and a locking bolt 802. The two locking holes 801 are opened at the top of the fixed post 200 and are respectively connected to two branch holes 201. The locking bolt 802 is threaded into the locking hole 801 and can press the branch line through the threaded connection to connect it to the power board.

[0026] The working principle of the electrical installation engineering line connecter provided by this utility model is as follows:

[0027] When the branch line enters the fixed post 200, it pushes the sliding sleeve 700, which was originally close to the connector 100 under the action of the spring 708, to move away from the connector 100. The sliding sleeve 700 slides in the sliding groove 704, and the internal limiting ramp 703 moves accordingly. Since the limiting ramp 703 is thicker closer to the connector 100, as the sliding sleeve 700 moves, the limiting ball 701 rolls on the limiting ramp 703 and is gradually pressed into the limiting groove 702. During the pressing process, the ball exerts pressure on the branch line, thereby firmly fixing the branch line in the fixed post 200. In this way, when using the locking assembly 800 (such as tightening the locking bolt 802), the branch line will not fall off the terminal, and the installer does not need to re-fix the branch line, which greatly shortens the wiring time and improves work efficiency.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
