Description

Technical Field

[0001] This utility model relates to the field of signal isolators, specifically to a snap-on signal isolator. Background Technology

[0002] A signal isolator is an electronic component that uses semiconductor modulation to transform signals to ensure absolute independence between the transformed signal, power supply, and ground, and is used to protect downstream control loops. It can reduce the impact of environmental noise on test circuits and suppress interference from unknown pulse devices. It is usually installed on a rail in a distribution cabinet using a snap-fit ​​method.

[0003] While existing snap-on signal isolators are easy to install on rails due to their snap-on structure, disassembly requires tools to pry them open because the snap-on structure is obstructed by the isolator and rail. This makes disassembly inconvenient. Therefore, a snap-on signal isolator is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a snap-on signal isolator, which solves the problem that although the existing snap-on signal isolators are easy to install on the guide rail through the snap-on structure, they are not convenient to disassemble because the snap-on structure is blocked by the signal isolator and the guide rail. Therefore, tools are needed to pry them open to disassemble them, which makes the disassembly of the signal isolator inconvenient.

[0005] This utility model provides the following technical solution: a snap-on signal isolator, including a signal isolator, a slot is provided at the bottom side of the signal isolator, a spring-loaded component is provided at the bottom of the signal isolator, a sliding component is provided at the outer end of the spring-loaded component, and a pulling component is provided at the side end of the sliding component.

[0006] As a preferred embodiment of the above technical solution, the rebound assembly includes a fixing frame, which is fixedly connected to the bottom of the signal isolator. A round rod is fixedly connected between the inner sides of the fixing frame, and a spring is sleeved on the outer end of the round rod.

[0007] As a preferred embodiment of the above technical solution, a sliding groove is provided on the outer side of the fixing frame.

[0008] As a preferred embodiment of the above technical solution, the sliding assembly includes a housing, which is fitted onto the outer end of the fixed frame. A sleeve plate is fixedly connected to the inner bottom end of the housing. The sleeve plate is fitted onto the outer end of the round rod. One end of the spring is fixedly connected to the inner side end of the fixed frame, and the other end of the spring is fixedly connected to the side end of the sleeve plate.

[0009] As a preferred embodiment of the above technical solution, a slider is fixedly connected to the inner side of the outer shell, the slider is slidably connected in the groove, and a slot is provided on the top of the outer shell.

[0010] As a preferred embodiment of the above technical solution, the pulling component includes a pull plate, which is fixedly connected to the side end of the housing. The side end of the pull plate is provided with a pull groove, and the inner wall of the pull groove is fixedly connected with a number of protrusions.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention utilizes a combination of a spring-loaded component, a sliding component, and a pulling component to form a snap-fit ​​structure. Pulling the pull groove moves the pull plate and the outer casing, while the slider slides within the groove, improving the stability of the outer casing's movement. The outer casing then moves the sleeve plate, which compresses the spring to retract. At this point, the groove can move away from the side of the guide rail, no longer limiting the guide rail's movement. This facilitates the disassembly of the signal isolator. Because the pull plate is located on the outer end of the signal isolator, the snap-fit ​​structure is easily pulled, avoiding obstruction by the signal isolator and guide rail. It can be disassembled without the need for tools, thus simplifying the removal of the signal isolator. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] like Figures 1-4As shown, this utility model provides a technical solution: a snap-fit ​​signal isolator, including a signal isolator 1. The bottom side of the signal isolator 1 has a slot 101. The bottom of the signal isolator 1 has a spring-loaded component 2. The outer end of the spring-loaded component 2 has a sliding component 3. The side end of the sliding component 3 has a pulling component 4. The spring-loaded component 2, the sliding component 3 and the pulling component 4 are arranged to form a snap-fit ​​structure. Since the pulling component 4 is set on the outer side of the signal isolator 1, the snap-fit ​​structure is easy to pull and avoids being blocked by the signal isolator 1 and the guide rail. It can be disassembled without using tools to pry it up, thus facilitating the disassembly of the signal isolator 1.

[0020] As one implementation method in this embodiment, such as Figure 1 , Figure 3 and Figure 4 As shown, the rebound assembly 2 includes a fixed frame 201, which is fixedly connected to the bottom of the signal isolator 1. A round rod 202 is fixedly connected between the inner sides of the fixed frame 201. A spring 203 is sleeved on the outer end of the round rod 202. A sliding groove 204 is opened on the outer side of the fixed frame 201. The sliding assembly 3 includes a housing 301, which is sleeved on the outer end of the fixed frame 201. A sleeve plate 304 is fixedly connected to the bottom inner end of the housing 301. The sleeve plate 304 is sleeved on the outer end of the round rod 202. One end of the spring 203 is fixedly connected to the inner side of the fixed frame 201, and the other end of the spring 203 is fixedly connected to the side end of the sleeve plate 304. A slider 302 is fixedly connected to the inner side of the housing 301. The slider 302 is slidably connected in the sliding groove 204. A slot 303 is opened on the top of the housing 301. Component 4 includes a pull plate 401, which is fixedly connected to the side of the housing 301. The side of the pull plate 401 has a pull groove 402, and the inner wall of the pull groove 402 is fixedly connected with several protrusions. The protrusions are designed to improve the anti-slip properties of the pull groove 402 and facilitate manual pulling. In practice, by pulling the pull groove 402, the pull plate 401 and the housing 301 are moved. At this time, the slider 302 slides in the groove 204, improving the stability of the movement of the housing 301. At this time, the housing 301 moves the sleeve plate 304, and the sleeve plate 304 compresses the spring 203 to retract. At this time, the slot 303 can leave the side of the guide rail and no longer limit the guide rail. At this time, it is easy to disassemble the signal isolator 1. By aligning the slot 101 and the slot 303 with the guide rail in the same pulling method, it is easy to install the signal isolator 1 on the guide rail.

[0021] Working principle: By pulling the pull groove 402, the pull plate 401 and the outer shell 301 are moved. At this time, the slider 302 slides in the groove 204, which improves the stability of the movement of the outer shell 301. The outer shell 301 drives the sleeve plate 304 to move. The sleeve plate 304 compresses the spring 203 and retracts. At this time, the groove 303 can leave the side end of the guide rail and no longer limit the guide rail. At this time, it is easy to disassemble the signal isolator 1. Since the pull plate 401 is set on the outer end of the signal isolator 1, the entire buckle structure is easy to pull and avoids being blocked by the signal isolator 1 and the guide rail. It can be disassembled without the need to use tools to pry it up, thus facilitating the disassembly of the signal isolator 1.

[0022] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
