Description

Technical Field

[0001] This utility model relates to the field of GPC controller technology, and in particular to an anti-loosening device for GPC controllers. Background Technology

[0002] As a key component of generator sets, the GPC controller undertakes important functions such as generator parallel operation control, engine status monitoring, and comprehensive system protection. Under the complex mechanical environment of vibration and shock generated during continuous operation of the generator set, the stability of the GPC controller directly affects the response accuracy and operational safety of the entire control system.

[0003] Currently, GPC controllers mainly adopt two assembly methods: rail clip installation and direct bolt fixing. The rail clip installation method usually requires fixing the rail to the cabinet or base first, and then locking the controller to the rail using the back clip. The direct bolt fixing method involves passing the bolts through the preset mounting holes on the bottom of the controller and connecting them to the preset threaded holes on the base to achieve rigid fixation of the controller on the base.

[0004] However, GPC controllers fixed using only the two assembly methods described above are prone to slippage or loosening of bolts at the connection points with the guide rail under the vibration and impact generated by the continuous operation of the generator set. This can cause the GPC controller body to slip or derail, further loosening the external wiring terminals plugged into the top of the GPC controller, resulting in problems such as loose electrical connections, increased contact resistance, and momentary signal interruptions. Therefore, there is an urgent need to develop an anti-loosening device for GPC controllers. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide an anti-loosening device for GPC controllers, which aims to solve the technical problem that existing GPC controllers mainly adopt two assembly methods: guide rail clip installation or direct bolt fixing. Under the vibration and impact generated by the continuous operation of the generator set, the clips are easily slipped or the bolts are loosened at the connection position with the guide rail, causing the GPC controller body to slip or even derail, and further causing the external wiring terminals plugged into the top of the GPC controller to loosen.

The first connecting plate 13 and the second connecting plate 23 are respectively provided with a plurality of connecting holes 33, which are spaced apart along the length direction of the first connecting plate 13 or the second connecting plate 23. As a specific example, in this embodiment, the first connecting plate 13 and the second connecting plate 23 are respectively provided with five connecting holes 33, which are spaced apart along the length direction of the first connecting plate 13 or the second connecting plate 23. The connecting holes 33 are oblong holes, and their long axis is arranged along the length direction of the first connecting plate 13 or the second connecting plate 23.

The stepped structure is adapted to the top outer contour of the GPC controller 40, and the top of the stepped structure is provided with a second top plate 21, and the bottom is provided with a second connecting plate 23.

[0030] In practical applications, the working principle of the anti-loosening device for the GPC controller of this application can be as follows: First, the first clamping bracket 10 and the second clamping bracket 20 are respectively fitted onto the corresponding sides of the GPC controller 40, so that the inner surfaces of the first clamping bracket 10 and the second clamping bracket 20 are tightly fitted to the outer surface of the top of the GPC controller 40. Then, fasteners are passed through the corresponding through holes on the two mating first lugs or two second lugs to achieve a tight connection between the first clamping bracket 10 and the second clamping bracket 20 and to clamp the top of the GPC controller 40. It should be noted that in actual use, the GPC controller 40 is already fixed to the corresponding mounting rail using existing guide rail snap-on installation or direct bolt installation methods.

[0031] Next, use cable ties to first pass through the connection hole 33 of the first connecting plate 13, then around the bottom surface of the mounting rail at the bottom of the GPC controller 40, and finally pass through the corresponding connection hole 33 of the second connecting plate 23 and tighten and lock it, further enhancing the stability of the GPC controller 40 on the mounting rail, thereby preventing the external wiring terminals plugged into the GPC controller 40 from becoming loose due to the vibration of the GPC controller 40 body, and ensuring the normal operation of the GPC controller 40.

[0032] In summary, the beneficial effects of the anti-loosening device for the GPC controller of this utility model are as follows: by setting the first clamping frame and the second clamping frame to form a fixed space that matches the outer contour of the top of the GPC controller, the device achieves all-round contour wrapping and support of the top of the GPC. Combined with the fastening connection of multiple through holes on the first or second clamping frame and fasteners, and the cooperation of connecting holes and binding members to form a multi-layered fixation that encircles the GPC controller, a three-dimensional anti-loosening structure is constructed. This can effectively prevent the GPC controller from slipping or loosening, thereby effectively reducing the loosening rate of the wiring terminals and ensuring the normal operation of the GPC controller.
