Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of contactors, and in particular relates to a stable contactor installation structure. Background Art
[0002] A contactor is an automatic control device used to frequently connect and disconnect AC and DC circuits. It is widely used in power generation, distribution, and consumption, particularly in applications requiring frequent operation and remote control of high-voltage circuits. The primary function of a contactor is to use electromagnetic force to close and open a switch, making it suitable for controlling loads such as motors, lighting, and resistance furnaces.
[0003] When installing a contactor, the mounting rail is typically secured to the control box using bolts or other tools, and the contactor body is then clipped onto the mounting rail using the contactor's built-in snap mechanism. This structure allows the contactor body and mounting rail to be quickly connected using snaps. While the secured contactor body cannot fall off the mounting rail, it can still slide laterally on the mounting rail, making the contactor unstable during use and prone to displacement. This can lead to poor contact between the moving and static contacts, affecting the normal on / off of the circuit. Utility Model Content
[0004] The purpose of the utility model is to provide a stable contactor mounting structure. Through the action of the installer, the contactor body can be more stably fixed on one side of the mounting rail, thereby preventing the contactor body from shaking during use and preventing the occurrence of poor electric contact due to displacement of the contactor body. The utility model solves the problem that the existing contactor is not stable enough during use and may be displaced, which may cause poor contact between the moving and static contacts and affect the normal on-off of the circuit.
[0005] To achieve the above objectives, the present invention provides the following technical solutions:
[0006] A stable contactor mounting structure comprises a contactor body and a mounting rail, wherein the contactor body is slidably connected to the mounting rail;
[0007] A positioning bar is fixed on one side of the contactor body, and a guide plate is fixed on one side of the positioning bar;
[0008] A mounter is fixed on one side of the contactor body;
[0009] The installer includes a mounting shell, a telescopic rod is fixed inside the mounting shell, and a spring is sleeved on the outside of the telescopic rod;
[0010] An adjustment plate is fixed at one end of the telescopic rod, and a clamping block is fixed on the top of the adjustment plate;

[0024] The utility model has the following beneficial effects:
[0025] 1. The utility model fixes the contactor body to one side of the mounting rail through the action of the installer. In order to reinforce the installer, the clamping rod is rotated so that one end of the clamping rod is stuck between the two limit plates. At this time, the weight block drives the other end of the clamping rod to move downward, and the end close to the limit plate continuously lifts the handle upward to fix the clamping block more stably and clamp one side of the mounting rail, so that the contactor body can be more stably fixed to one side of the mounting rail, avoiding shaking of the contactor body during use and preventing poor electric contact due to displacement of the contactor body.
[0026] 2. In the present invention, the clamping plate is used so that when one end of the threaded rod approaches the contactor body, the clamping plate can be driven toward the contactor body. The clamping plate and the reinforcement plate can fix the mounting track from both sides to prevent the contactor body from sliding on the mounting track.
[0027] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
