Technical Field

[0001] This utility model relates to a device for fixing the outer shell of an isolator, and belongs to the technical field of isolator production equipment. Background Technology

[0002] An isolator is a device that uses linear optocoupler isolation to convert input signals to output signals, isolating the input, output, and power supply from each other. It is particularly suitable for use with equipment and instruments requiring electrical isolation. Also known as a signal isolator, it is an important component of industrial control systems and is typically mounted to a DIN rail using a connecting mechanism.

[0003] Existing signal isolators, when installed with guide rails, use a snap-fit ​​connection to connect to the guide rails. There will be gaps between the snap-fit ​​and the guide rail, making them prone to slippage under external force.

[0004] Therefore, this utility model proposes a new solution. Utility Model Content

[0005] The main purpose of this utility model is to provide an isolator housing fixing device to overcome the shortcomings of the existing technology.

A fixing latch is fixedly connected to the top of the mounting groove, and a movable latch is slidably installed at the bottom of the mounting groove. A clamping mechanism is provided between the mounting groove and the guide rail. The clamping mechanism includes a first spring fixedly connected to the side wall of the mounting groove, and a pressure plate abutting against the guide rail is fixedly connected to one end of the first spring.

[0008] Preferably, the clamping mechanism further includes a sleeve fixedly connected to the side wall of the mounting groove, and a slide rod fixedly connected to the side wall of the pressure plate and slidably connected to the sleeve, wherein the first spring is sleeved on the outer wall of the sleeve.

[0009] Preferably, an annular plate located outside the sleeve is fixedly connected to the side wall of the mounting groove.

[0010] Preferably, a rubber pad is fixedly connected to the side wall of the pressure plate near the guide rail.

[0011] Preferably, a fastening screw is installed at the top of the mounting groove, and the bottom end of the fastening screw abuts against the top of the guide rail.

[0012] Preferably, the top of the mounting groove is provided with a screw hole that mates with the fastening screw, and the top of the fastening screw is connected to a handle.

[0013] Preferably, one end of the movable latch is fixedly connected to a connecting rod, and a second spring is sleeved on the outer wall of the connecting rod.

[0014] Preferably, the bottom of the mounting groove is provided with a sliding groove that slides with the movable latch, a spring groove is provided below the sliding groove, and a sliding hole that slides with the connecting rod is provided below the spring groove.
