Abstract
The utility model discloses a novel auxiliary contact device of a ground switch, comprising a base, a main shaft, a moving-blade support plate, a closing spring, a microswitch, a locating rod and a baffle plate, wherein the baffle plate is in an L shape and supported at the lower side of the locating rod; the baffle plate is fixed on the locating rod through screws; the main shaft passes through an underframe and is vertically installed on the underframe; one end of the closing spring is pivoted on the underframe; the other end of the closing spring is pivoted on the moving-blade support plate; the locating rod passes through the underframe and is vertically installed on the underframe; and the locating rod is parallel with the main shaft. The L-shaped baffle plate is fixed at the lower side of the locating rod by three M5*10 hexagonal head screws, therefore, the baffle plate can provide an electric signal by pressing the microswitch when a ground switch is in a closing state; and the moving-blade support plate drives the locating rod to separate the baffle plate and the microswitch, and the microswitch is released to provide an opening signal when the ground switch is in an opening state.
Description
Technical field
The utility model 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 utility model 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 utility model 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 utility model 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 utility model is: the utility model 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 utility model 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.

Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.Fig. 1 is the structural representation of "on" position of the present utility model, the utility model comprises base 1, main shaft 2, moving knife support plate 3, switching-in spring 4, sensitive switch 5, backstay 6 and baffle plate 7, baffle plate 7 is " L " font, holder is below backstay 6, baffle plate 7 is fixed on the backstay 6 by screw 8, can select the hex head screw of 3 M5 * 10 here, this main shaft 2 passes underframe 1 and is vertically mounted on the underframe 1, switching-in spring 4 one ends are articulated on the underframe 1, the other end is articulated on the moving knife support plate 3, backstay 6 passes underframe 1 and is vertically mounted on the underframe 1, and backstay 6 is parallel with main shaft 2.Moving knife support plate 3 can be connected through the hinge with switching-in spring 4 in practice.
The hex head screw of baffle plate 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.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
