Abstract
The invention discloses a novel auxiliary contact device of a grounding switch. The auxiliary contact device comprises a base, a main shaft, a moving cutter support plate, a switch spring, a microswitch, a locating lever and a baffle; and the baffle takes the shape of a letter 'L' and is supported below the locating lever, the baffle is fixed on the locating lever by screws, the main shaft passes a base frame and is vertically arranged on the base frame, one end of the switch spring is pivotally jointed on the base frame, the other end of the switch spring is pivotally jointed on the moving cutter support plate, the locating lever passes the base frame and is vertically arranged on the base frame, and the locating lever is parallel to the main shaft. The baffle which takes the shape of the letter 'L' is fixed below the locating lever by three M5*10 hexagon head screws so that an electrical signal can be provided by pressing the microswitch by the baffle when the grounding switch is on; and when the grounding switch is off, the moving cutter support plate drives the locating lever to cause the baffle to be separated from the microswitch, thus an switch opening signal is provided by releasing the microswitch.
Description
Technical field
The present invention relates to a kind of contact making device, particularly relate to a kind of on backstay assembling one plate washer, the novel auxiliary contact device of grounding switch that baffle plate can pressured sensitive switch.
Background technology
JN15 series earthed switch original design does not have apparatus for auxiliary contact, after customer requirements installs apparatus for auxiliary contact additional, realizes dividing the incompatible function that the signal of telecommunication is provided by earthed switch, makes its safer repair apparatus.But the mode of installing additional is to drive cam by main shaft to press the sensitive switch action.Because it possesses the making current ability designing requirement of JN15 series earthed switch, so it has the characteristic of quick combined floodgate.Realize closing a floodgate fast, determined it that rotation idle stroke of 60 ° is arranged when main axis rotation occurring when divide-shut brake.As a result, adopt main shaft to drive the mode of cam, can not realize the sensitive switch action reliably.Bring very big adjustment difficulty to the user, customer complaint increases.If make earthed switch at opening and closing state, realize reliably pressing sensitive switch, the correct signal of telecommunication is provided, can only lean on the action of moving knife to control the sensitive switch action; If adopt moving knife directly to control the sensitive switch action, structure will be very complicated, increase the manufacture difficulty and the cost of earthed switch.
Summary of the invention
At the problems referred to above, main purpose of the present invention is to provide a kind of plate washer that assembles on backstay, baffle plate can pressured sensitive switch novel auxiliary contact device of grounding switch, the present invention solves above-mentioned technical problem by following technical proposals: a kind of novel auxiliary contact device of grounding switch, it comprises base, main shaft, the moving knife support plate, switching-in spring, sensitive switch, it is characterized in that: described contact making device also comprises backstay and baffle plate, described baffle plate is " L " font, holder is below backstay, baffle plate by screw on backstay, described main shaft passes underframe and is vertically mounted on the underframe, described switching-in spring one end is articulated on the underframe, the other end is articulated on the moving knife support plate, described backstay passes underframe and is vertically mounted on the underframe, and backstay is parallel with main shaft.
Wherein, described screw is the hex head screw of M5 * 10.
Wherein, described moving knife support plate and switching-in spring are connected through the hinge.
The course of work of the present invention is as follows: the hex head screw of the baffle plate that will be " L " font by 3 M5 * 10 be fixed on backstay below, make baffle plate when the earthed switch "on" position, reliably press sensitive switch, the signal of telecommunication is provided; When the earthed switch gate-dividing state, the moving knife support plate drives backstay, and baffle plate and sensitive switch are broken away from, and sensitive switch discharges, and sub-gate signal is provided.
Positive progressive effect of the present invention is: the present invention has following advantage:
1. solved earthed switch and can correctly show the problem that the high-pressure side is charged at closing position;
2. transform earthed switch divide-shut brake positioner, when being implemented in the divide-shut brake position, can reliably press sensitive switch, correctly show the signal of telecommunication;
3. Chong Xinsheji apparatus for auxiliary contact correctly shows the signal of telecommunication in the time of can realizing the divide-shut brake position.
The present invention is simple in structure, thinking is new reasonable, reliable in action, do not have loaded down with trivial details adjustment process, can realize the expansion of auxiliary contact quantity, fully satisfies the user to multifinger requirement.Improve properties of product greatly, reduced manufacturing cost, won user's favorable comment.
