Description

Technical Field

[0001] This invention relates to the field of electrical circuit technology, and in particular to a sealing assembly for electrical circuits. Background Technology

[0002] Electrical circuits, as key components for connecting and transmitting electrical energy between electrical devices, play a vital role in various power systems and electronic equipment. To ensure the reliability and safety of electrical circuit connections, it is necessary not only to guarantee good conductivity but also to effectively seal and dustproof the connection points to prevent moisture, dust, and other impurities from the external environment from intruding and affecting the normal operation of the electrical circuits.

[0003] Chinese patented invention CN215911702U discloses a quick installation mechanism for electrical circuits, comprising: an insulating outer body, a protective sleeve, a connecting conductor, a wire hole, a sealing ring, a limiting groove, a clamping block, a bearing, a locking bolt, an insulating bolt, and anti-slip teeth; the insulating outer body is rectangular; the protective sleeve is disposed inside the insulating outer body and is embedded therein; the connecting conductor is disposed inside the protective sleeve and is embedded therein; a wire hole is provided at each of the left and right ends of the connecting conductor, and the wire hole passes through the insulating outer body and communicates with the outside; the sealing ring is disposed at one end of the wire hole and is embedded therein; this utility model improves upon the quick installation mechanism for electrical circuits. It has the advantages of reasonable structure, good conductivity, stable connection, improved maintenance efficiency, convenient use, and improved safety, thus effectively solving the problems and shortcomings proposed in this utility model. However, its device still has some problems. In actual use, the fixing method of this device requires rotating two insulating bolts separately to fix the two wires to the adapter conductor. The need to rotate two insulating bolts separately increases the operation steps and difficulty, reduces the installation efficiency, and since rotating the insulating bolts separately may lead to inconsistent fixing force, it will affect the stability and reliability of the connection and pose a potential safety risk. Therefore, we propose a sealing component for electrical circuits to solve the above problems. Summary of the Invention

[0004] To address the above shortcomings, the purpose of this invention is to provide a sealing component for electrical circuits.

[0005] The technical solution adopted by the invention is a sealing component for electrical circuits. Its key technical features include a housing, an internal adapter conductor, a protective sleeve on the adapter conductor, connecting grooves on both sides of the adapter conductor, two insertion holes on the housing that communicate with corresponding connecting grooves, mounting grooves on the insertion holes, and a sealing ring fixedly connected to the mounting grooves. A cavity is formed on the housing, with two insulating rods rotatably connected to the top inner wall of the cavity. An insulating rod is threaded onto each insulating rod, and the end of each insulating rod extends into the adapter conductor and is fixedly connected to an arc-shaped insulating block. A pulley is fixedly connected to each insulating rod, and the two pulleys are connected to the same belt. The top of one of the insulating rods extends out of the housing and is welded with a knob. A T-shaped rod is provided on the knob, and a spring is fixedly connected between the bottom inner wall of the T-shaped rod and the bottom of the housing. Multiple slots are formed in a ring shape on the top of the housing, and the T-shaped rod engages with one of the multiple slots.

[0006] Furthermore, a connecting wire is movably contacted on the connecting groove, and the connecting wire is movably contacted with the corresponding arc-shaped insulating block.

[0007] Furthermore, the knob has a guide hole, and the knob is slidably connected to the T-shaped rod through the guide hole.

[0008] Furthermore, the insulating rod has a threaded hole, and the insulating rod is threadedly connected to the corresponding insulating screw through the threaded hole.

[0009] Furthermore, an installation hole is provided on the top inner wall of the cavity, and a bearing is fixedly connected to the inner wall of the installation hole. The inner side of the inner ring of the bearing is welded to the outer side of one of the two insulating wire rods.

[0010] Furthermore, the spring is movably sleeved on the T-shaped rod.

[0011] The beneficial effects of this invention are as follows: This sealing assembly for electrical circuits, by pulling the T-shaped rod, stretches the spring, separating the T-shaped rod from the slot. Rotating the knob, via a pulley and belt drive, causes two insulating rods to rotate simultaneously. The insulating rods, through the insulating rod, drive the corresponding arc-shaped insulating blocks to move, thus fixing the connecting wires. Releasing the pull on the T-shaped rod at this point causes the stretched spring to return to its original position, and the spring drives the T-shaped rod to engage with another slot among multiple slots. This allows for the simultaneous fixing of two connecting wires, improving installation efficiency and ensuring consistent fixing force, thus guaranteeing the stability of the two connecting wires. The sealing ring also provides a dustproof seal, preventing dust from entering the housing through the insertion hole. Attached Figure Description

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the following description is provided in conjunction with the accompanying drawings. Figures 1-5 The present invention will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-5As shown, an embodiment of this utility model discloses a sealing assembly for electrical circuits, including a housing 1, a transition conductor 2 inside the housing 1, a protective sleeve 3 fitted onto the transition conductor 2, connecting grooves 4 on both sides of the transition conductor 2, two insertion holes 5 on the housing 1, the insertion holes 5 communicating with the corresponding connecting grooves 4, mounting grooves 6 on the insertion holes 5, and sealing rings 7 fixedly connected to the mounting grooves 6, and a cavity 8 on the housing 1, with two insulating screws 9 rotatably connected to the top inner wall of the cavity 8. An insulating rod 10 is threaded onto the lead screw 9. The end of the insulating rod 10 extends into the adapter conductor 2 and is fixedly connected to an arc-shaped insulating block 11. A pulley 12 is fixedly connected to the insulating lead screw 9, and the same belt 13 is connected to the two pulleys 12 for transmission. The top of one of the two insulating lead screws 9 extends to the outside of the housing 1 and is welded to a knob 14. A T-shaped rod 15 is provided on the knob 14. A spring 16 is fixedly connected between the bottom inner wall of the T-shaped rod 15 and the bottom of the housing 1. The top of the housing 1 is ring-shaped. The device has multiple slots 17. A T-shaped rod 15 engages with one of the slots 17. Pulling the T-shaped rod 15 stretches the spring 16 during its movement, simultaneously disengaging the T-shaped rod 15 from one of the slots 17. Then, rotating the knob 14, which is driven by the pulley 12 and belt 13, causes the two insulating rods 9 to rotate simultaneously. The insulating rods 9, through the insulating rod 10, drive the corresponding arc-shaped insulating blocks 11 to move, causing the arc-shaped insulating blocks 11 to move. 1. Fix the connecting wire 18. At this time, release the pull on the T-shaped rod 15. The spring 16, which is in the stretched state, returns to its original state. Under the action of its own elastic force, the spring 16 drives the T-shaped rod 15 to engage with another slot 17 among the multiple slots 17, so that two connecting wires 18 can be fixed at the same time, improving installation efficiency. The fixing force is the same, which ensures the stability of the two connecting wires 18. The sealing ring 7 plays a role in sealing and dust prevention, preventing dust from entering the interior of the housing 1 through the plug hole 5.

[0021] Connecting wire 18 is in movable contact on connecting groove 4. Connecting wire 18 is in movable contact with corresponding arc-shaped insulating block 11. The arc-shaped insulating block 11 is set to fix it.

[0022] A guide hole is provided on the knob 14, and the knob 14 is slidably connected to the T-shaped rod 15 through the guide hole.

[0023] The insulating rod 10 has a threaded hole, and the insulating rod 10 is threadedly connected to the corresponding insulating screw 9 through the threaded hole. The insulating rod 10 serves as a connection.

[0024] An installation hole is provided on the top inner wall of cavity 8. A bearing is fixedly connected to the inner wall of the installation hole. The inner side of the inner ring of the bearing is welded to the outer side of one of the two insulating wire rods 9.

[0025] Spring 16 is movably sleeved on T-shaped rod 15, and the setting of spring 16 plays the role of resetting.

[0026] Working principle or structural principle: During use, the connecting wire 18 is separated from the housing 1. During installation, pulling the T-shaped rod 15 stretches the spring 16 as it moves, simultaneously separating the T-shaped rod 15 from one of the multiple slots 17. Then, rotating the knob 14, which, via the pulley 12 and belt 13, causes the two insulating rods 9 to rotate simultaneously. The insulating rods 9, through the insulating rod 10, drive the corresponding arc-shaped insulating blocks 11 to move, causing the arc-shaped insulating blocks 11 to... 1. Fix the connecting wire 18. At this time, release the tension on the T-shaped rod 15. The spring 16, which is in a stretched state, returns to its original state. Under the action of its own elasticity, the spring 16 drives the T-shaped rod 15 to engage with another slot 17 among the multiple slots 17, so that two connecting wires 18 can be fixed at the same time, improving installation efficiency. The fixing force is the same, which ensures the stability of the two connecting wires 18. The sealing ring 7 plays a role in sealing and dust prevention, preventing dust from entering the interior of the housing 1 through the plug hole 5.
