Description

Technical Field

[0001] This utility model relates to the field of electrical test board technology, and in particular to an electrical test board. Background Technology

[0002] On ships, marine electrical equipment is the core guarantee for the safe operation of the ship, and the efficiency of its maintenance, fault diagnosis and repair directly affects the ship's operational safety and economic benefits.

[0003] Currently, ships are generally equipped with electrical test boards to facilitate marine electrical maintenance. However, as shown in the marine electrical test board disclosed in application number 201721580943.1, current marine electrical test boards generally include an independent enclosure and a cover plate. Control switches or buttons are generally mounted on the cover plate, and the cover plate is hinged to the enclosure. Due to the assembly gap, if the cover plate is pressed, it is easy to collide with the enclosure and generate noise. Furthermore, due to the function of the electrical test board, the operator needs to frequently operate the component switches mounted on the cover plate. This makes the electrical test board with excessive assembly gaps prone to generating more noise. Currently, electrical test boards generally do not have noise reduction treatment, so improvements are needed. Utility Model Content

The test panel has an integrally formed U-shaped outer panel on its rear side, and the front side of the box has an inner panel that is also U-shaped. The outer panel is fitted over the inner panel, and the outer panel and the inner panel are connected by a hinge to allow the test panel to be hinged. The rear side of the test panel is provided with an elastic material that can be attached to the front end of the inner panel.

[0006] Preferably, the elastic material is a rubber pad.

[0007] Preferably, the leading edge of the outer side of the inner cladding extends outward to increase the contact area with the elastic material.

[0008] Preferably, the test panel is equipped with a latch, and the latch has a controllable rotating locking tongue that hooks onto the outwardly extending area of ​​the front edge of the inner panel.

[0009] Preferably, the test panel is provided with a voltage and current display area, a circuit breaker control area, a test switch group, a socket test area, a lamp holder test area, an output test terminal area, and two fluorescent lamp test areas.
