Description

Terminal strip with checking function

Technical Field

The utility model relates to a terminal row who possesses inspection function.

Background

The leap-type development of electric energy technology directly promotes electric energy to become indispensable energy, and further leads to the increasing volume and scale of power grids in the last decade. The expansion of volume and scale has directly led to a explosive increase in the number of power equipment.

The terminal strip is very important as a connection hub between power devices, and plays a role in signal (voltage, current) transmission. The terminal strip is arranged, so that the wiring is attractive and convenient to maintain. Especially, when the connection between remote lines is carried out, the connection is firm, and the technical construction and the later maintenance are convenient.

While the terminal strip brings convenience to wiring and maintenance of the power equipment, some inherent defects of the terminal strip are gradually exposed. The terminal block is usually mounted on both sides of the apparatus, typically at a height of about 2 m. Because it is placed in screen cabinet both sides, spatial position is narrow, and this has just led to it to have the wiring insecure to lead to the condition that the external connection does not communicate with the terminal row, and this will bring very big risk for power equipment operation.

With the rapid increase of the number of electric power equipment, the increasing shortage of human resources causes contradiction between equipment and manpower, and the possibility that the equipment runs with risks is increased straightly. Therefore, there is a great need for an optimized design of the existing terminal block and wiring to meet the reduction of the risk.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1, a terminal row that possesses inspection function, including terminal row body 1, terminal row body up end has been seted up directly over every wiring jack 4 and has been detected counter bore 5, and it is equipped with terminal reference numeral apron 6 to detect counter bore upper end cover, detects counter bore lower extreme through the wiring jack of vertical hole 7 intercommunication rather than corresponding, wears to be equipped with in the vertical hole and detects supplementary conducting rod 8, and supplementary conducting rod is provided with spring 9, and the spring lower extreme supports and leans on the terminal row body, and the upper end supports and leans on supplementary conducting rod, and when the spring does not receive the force, supplementary conducting rod lower extreme is located wiring jack top.

In this embodiment, the upper end of the auxiliary conductive rod is provided with a conductive pressing plate portion 10, the conductive pressing plate portion is located in the detection counter bore, and the upper end of the spring abuts against the lower side surface of the conductive pressing plate portion.

In this embodiment, the vertical hole is a stepped hole with a large upper portion and a small lower portion, the spring is located on the upper portion of the vertical hole, and the lower end of the spring abuts against the stepped surface of the vertical hole.
