Example Embodiment

[0027] Implementation mode one

[0028] The auxiliary circuit plug-in unit is composed of plug 2 and socket 1. The plug 2 and the socket 1 are made of insulating and flame-retardant plastics, except for the conductive body used for power supply and gas connection.

[0029] The plug 2 is press-fitted with a plug contact reed 3 with an arc-shaped contact 4 on the top (the plug contact point can be any form of contact guide point, this embodiment is preferably a plug contact reed 3 with an arc-shaped contact 4), There are two upper and lower contact reeds 3, and an insulating plastic isolation layer is arranged between the two contact reeds 3. The back end of the plug 2 is a plug terminal 5, and the plug terminal 5 is provided with a wiring hole 6 corresponding to the plug contact body. The structure design of the plug 2 is basically similar to that of various types of auxiliary circuit plugs. The socket 1 is press-fitted with an upper conductive reed 7, a middle conductive reed 8, ...

Example Embodiment

[0034] Implementation mode two

[0035] The difference between this embodiment and the first embodiment is that the upper, middle, and lower conductive reeds are set to the left, middle, and right conductive reeds, and the plug contact points at the end of the plug 2 are set to the left and right arrangement (that is, the up and down arrangement is changed For the horizontal arrangement). The rest is the same as the first embodiment.

Example Embodiment

[0036] Implementation mode three

[0037] The difference between this embodiment and the above embodiments lies in: in order to facilitate the production of conductive reeds, the middle conductive reed 8 can be set to be the same length as the upper and lower conductive reeds, but the middle conductive reed 8 except for the connection position The other parts are wrapped with insulator to ensure that the circuit is disconnected at other positions except the test and connection positions.

Abstract

The invention relates to a plugging device having an auxiliary contact. The plugging device is characterized in that the device comprises a socket (1), a plug (2), and a position display unit. A first conductor, a second conductor and a third conductor are arranged on the socket (1); and the plug (2) is provided with a plug contact body in electric connection with the first conductor, the second conductor and the third conductor. When the plug (2) is inserted into the socket (1), the plug contact body is connected with the first conductor, the second conductor and the third conductor at a testing position to form a testing loop, thereby triggering the position display unit to display the testing position. At a connecting position, the plug contact body is connected with the second conductor and the third conductor to form a connection loop, so that the position display unit displays the connecting position. The plugging device has technical effects of low cost and high reliability.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a plug-in device with auxiliary contacts. Background technique [0002] In the modern distribution network and engineering construction, the withdrawable low-voltage distribution cabinet is widely used in power plants, substations and other occasions; the distribution cabinet is used as the power conversion, distribution and distribution of power distribution, motor control and lighting distribution equipment Control plays an important role. This type of distribution cabinet has the advantages of saving space, reliable operation, convenient installation and maintenance, strong breaking capacity, and multiple outgoing circuits. [0003] The national standard GB7251 stipulates that in the withdrawable low-voltage power distribution cabinet, each circuit should have an operating mechanism for advancing and withdrawing in the three positions of connection, test a...
