Description

Technical Field

[0001] This utility model relates to the technical field of circuit protection components, and in particular to a cut-out bushing. Background Technology

[0002] The compressor is an important component of refrigeration equipment. Because there are many wires on the compressor and the installation space is relatively narrow, the narrow area can cause friction on the wires or wire joints under vibration, which can easily damage the wires or wire joints and affect the normal use of the compressor. In this regard, this application provides a cut-out bushing for protecting the wires or wire joints. Summary of the Invention

[0003] The main purpose of this utility model is to overcome the shortcomings of the prior art and provide a cut-out bushing.

[0004] The technical solution adopted by this utility model to achieve its technical objective is a cut bushing, which includes a bushing body formed by rolling. The bushing body is set as a hollow cylinder. After the bushing body is rolled, a groove is formed along the axial direction. The bushing body is formed by rolling metal sheets such as iron sheets. Due to the presence of the groove, compared with a bushing with a complete cylindrical structure, it can save some material and improve the processing speed.

[0005] Preferably, it also includes a grid assembly for routing the wires, the grid assembly including a grid mesh with a cylindrical structure, a rubber ring fixedly wound around the outer surface of the grid mesh, and a magnetic ring fixedly wrapped around the outside of the rubber ring; the grid mesh is set at the same height as the bushing body, and multiple grid channels are provided inside it to facilitate the separation of multiple wires from each other.

[0006] The inner wall of the bushing body is coated with a first magnetic layer, and the magnetic ring is attached to the first magnetic layer. The grid assembly is installed inside the bushing body by magnetic connection between the magnetic ring and the first magnetic layer.

[0007] Preferably, one side of the rubber ring is fixedly bonded to both ends of the grid mesh, and the other side is fixedly bonded to the magnetic ring. The rubber ring and the magnetic ring are positioned correspondingly and have the same axial width. When the grid assembly is placed inside the bushing body, the rubber ring provides a certain elastic force, thereby forming a compressive force on the inner wall of the bushing body, which is more conducive to the installation stability of the grid assembly. At the same time, the rubber ring has an insulating function.

[0008] Preferably, it further includes a separator assembly for routing the circuit, the separator assembly including a partition, with rubber blocks fixedly bonded to both ends of the partition, and a magnetic block with an arc-shaped structure fixedly bonded to one side of the outer wall of the rubber block, the magnetic block being configured with an arc-shaped structure to facilitate fitting with the inner wall of the bushing body.

[0009] The inner wall of the bushing body is coated with a second magnetic layer, and the magnetic block is attached to the second magnetic layer; through the magnetic connection of the magnetic block and the second magnetic layer, the entire partition assembly is installed inside the bushing body.

[0010] Preferably, a snap-fit ​​groove is provided on the side of the middle end of the partition, and every two partitions are set as a group for use together. Multiple groups can be set inside the bushing body, and every two partitions are snapped together through the snap-fit ​​groove.

[0011] Preferably, the angle at which each pair of partitions is fastened is set to 90 degrees, that is, each pair of partitions is fastened perpendicularly to each other.

[0012] Preferably, both the first magnetic layer and the second magnetic layer are made of metal powder that can cooperate with a magnet, and the metal powder is coated on the entire inner wall of the bushing body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This cut-out bushing can prevent direct contact between the wiring and a narrow area of ​​the compressor, protecting the wiring or wiring connectors. Furthermore, the bushing body is made of rolled metal sheets such as iron, which saves material and increases processing speed compared to bushings with a complete cylindrical structure.

[0015] Furthermore, this cut bushing, through the setting of the grid assembly and the separator assembly, can effectively separate multiple lines, making it easier to find the lines later or to avoid multiple lines getting tangled together, which can easily cause the wire ends to come off due to pulling. More importantly, the assembly and bushing body are easy to install and can be used selectively, offering high flexibility. Attached Figure Description

However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model. Example 1

[0025] Please see Figure 1-2 A cut bushing includes a bushing body 1 formed by rolling and a grid assembly for routing the wiring.

[0026] The bushing body 1 is set as a hollow cylinder. After being rolled, the bushing body 1 has a groove 101 formed along the axial direction. The bushing body 1 is made by rolling metal sheets such as iron sheets. Due to the presence of the groove 101, compared with a bushing with a complete cylindrical structure, it can save some material and increase the processing speed.

[0027] The grid assembly includes a grid mesh 2 with a cylindrical structure. A rubber ring 201 is fixedly wound around the outer surface of the grid mesh 2, and a magnetic ring 202 is fixedly wrapped around the outside of the rubber ring 201. The grid mesh 2 is set at the same height as the bushing body 1, and multiple grid channels are provided inside it to separate multiple wires from each other. The inner wall of the bushing body 1 is coated with a first magnetic layer 203, and the magnetic ring 202 is adsorbed and connected to the first magnetic layer 203. The first magnetic layer 203 is made of metal powder that can cooperate with magnets, and the metal powder is coated on the entire inner wall of the bushing body 1. The grid assembly is installed inside the bushing body 1 by the magnetic connection between the magnetic ring 202 and the first magnetic layer 203.

[0028] One side of the rubber ring 201 is fixedly bonded to both ends of the grid mesh 2, and the other side is fixedly bonded to the magnetic ring 202. The rubber ring 201 and the magnetic ring 202 are positioned correspondingly and have the same axial width. When the grid assembly is placed inside the bushing body 1, the rubber ring 201 provides a certain elastic force, thereby forming a compressive force on the inner wall of the bushing body 1, which is more conducive to the installation stability of the grid assembly. At the same time, the rubber ring 201 has an insulating function.

[0029] Specifically, in use, when using the bushing body 1, the circuit can be connected in series inside the bushing body 1 to protect the circuit or circuit connector.

[0030] When using the bushing body 1 and the grid assembly, by squeezing the magnetic rings 202 at both ends of the grid assembly by hand, the magnetic rings 202 can retract towards the center of the grid mesh 2 due to the setting of the rubber rings 201. Then, the magnetic rings 202 can be installed inside the bushing body 1, thereby magnetically installing the entire grid assembly inside the bushing body 1. At the same time, the rubber rings 201 form a compressive force on the inner wall of the bushing body 1, which is more conducive to the installation stability of the grid assembly. Finally, the wires or wire connectors can be connected in series to separate multiple wires. Example 2

[0031] Please see Figure 1 , 3 4. The cut bushing includes a bushing body 1 formed by rolling, and a separator assembly for routing the circuit.

[0032] The bushing body 1 is set as a hollow cylinder. After being rolled, the bushing body 1 has a groove 101 formed along the axial direction. The bushing body 1 is made by rolling metal sheets such as iron sheets. Due to the presence of the groove 101, compared with a bushing with a complete cylindrical structure, it can save some material and increase the processing speed.

[0033] The partition assembly includes a partition plate 3, with rubber blocks 301 fixedly bonded to both ends of the partition plate 3. A magnetically attached block 302 with an arc-shaped structure is fixedly bonded to one outer wall of each rubber block 301. The arc-shaped magnetically attached block 302 facilitates a proper fit with the inner wall of the bushing body 1. The inner wall of the bushing body 1 is coated with a second magnetic layer 303, and the magnetically attached block 302 is adsorbed onto the second magnetic layer 303. The second magnetic layer 303 is made of metal powder capable of engaging with a magnet, and the metal powder is coated on the entire inner wall of the bushing body 1. Through the magnetic connection of the magnetically attached block 302 and the second magnetic layer 303, the partition assembly is installed entirely inside the bushing body 1.

[0034] Furthermore, in this embodiment, a snap-fit ​​groove 304 is provided on the side of the middle end of the partition 3, and each pair of partitions 3 is set as a group for use. Multiple groups can be set inside the bushing body 1, and each pair of partitions 3 are snapped together by the snap-fit ​​groove 304.

[0035] Furthermore, in this embodiment, the angle at which every two partitions 3 are fastened is set to 90 degrees, that is, every two partitions 3 are fastened perpendicularly to each other.

[0036] Specifically, in use, when using the bushing body 1, the circuit can be connected in series inside the bushing body 1 to protect the circuit or circuit connector.

[0037] When using the bushing body 1 and the partition assembly, by squeezing the magnetic blocks 302 at both ends of the partition assembly by hand, the magnetic blocks 302 can retract towards the middle of the partition 3 due to the setting of the rubber block 301. Then the magnetic blocks 302 can be installed inside the bushing body 1, thereby magnetically installing the entire partition assembly inside the bushing body 1. At the same time, the rubber block 301 forms a squeezing force on the inner wall of the bushing body 1, which is more conducive to the installation stability of the partition assembly. Finally, the wires or wire connectors can be connected in series to separate multiple wires.
