Abstract
The utility model relates to a circuit fuse device, mainly used in a switch and a socket. The circuit fuse device is composed of a casing, a bracket and a fuse pipe. One end of the casing is sealed. The other end of the casing is opened. The fuse pipe is clamped in the clamp position of the bracket. The bracket is arranged in the casing. Both conductive ends of the fuse pipe are clamped through two conductor clamp sheets fixed at a seal end in the casing. The clamp sheets are connected with two wiring hole on the outer side of the seal end of the casing. Because the fuse pipe and the conductor clamp sheets are all sealed and wrapped in the insulation casing, the circuit fuse device can not be damaged easily. Meanwhile, ashort circuit and an electrical leak fault can be avoided. The circuit fuse device has the advantages of high safety and convenient operation.
Description
The utility model is a kind of circuit safeties, especially a kind of safeties that are used in single-phase electricity switch or the supply socket.
The single phase poaer supply switch on the present indoor electric line and the safeties of supply socket, be the frame mode that adopts at switch panel and the inner installation insurance pipe of socket panel (silk) mostly, this kind mode has been omitted the normal in the past safety box that uses, has compact conformation, advantages such as it is few to take up space, and elegant in appearance, expense is lower.But the protective tube in existing mains switch and the socket all is to be installed in the unlimited insurance pipe clamp, the conductive metal sheet at protective tube two ends exposes, when switch and socket are installed, or in maintenance process, the conducting strip at insurance pipe clamp two ends contacts with other current-carrying part easily and is short-circuited, faults such as electric leakage, protective tube also damages because of mechanism easily simultaneously.
The purpose of this utility model provides a kind of protective tube, the insurance pipe clamp does not expose, and is safe and reliable, the circuit safeties that contact resistance is little, assembling is easy to use.
For achieving the above object, the utility model is by housing, and carriage, protective tube are formed, housing is the ellipse garden of an insulation cylindrical cavity, the one end opening, other end sealing, blind end is provided with two wiring holes and terminal screw outward, the blind end internal fixation has two intermediate plates, intermediate plate links to each other with wiring hole, the translot shape screens that carriage is provided with loam cake and matches with protective tube, and protective tube is installed in the screens of translot shape, carriage is inserted in the housing from the shell nozzle end, and the protective tube two ends are clamped by intermediate plate.
The utility model since with protective tube, protective tube intermediate plate all sealing be wrapped in the insulation shell, so protective tube is not fragile, has avoided the generation of short circuit, leak current fault, the security reliability height yet.During assembling, protective tube is stuck in the screens of carriage, directly carriage is inserted in the housing then and get final product, use very convenient.
Accompanying drawing 1 is the utility model stereogram.
Accompanying drawing 2 is the utility model decomposing state figure.
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in drawings, the utility model is by housing (1), carriage (2), protective tube (3) is formed, housing (1) is made with insulating material, it is an elliptical cylinder-shape cavity, the one end opening, other end sealing, blind end is provided with two wiring holes (4) outward, the tubular structure that wiring hole (4) is made for electric conducting material, its side disposes corresponding terminal screw, be fixed with two intermediate plates (5) separated by a distance respectively with screw in the blind end, wherein the screw blind end that passes housing (1) is connected with wiring hole (4), form electric pathway, carriage (2) is made by insulating material, the upper end of carriage (2) is loam cake (6), and loam cake (6) below is provided with the translot shape screens (7) that matches with protective tube (3) shape, and protective tube (3) is installed in the translot shape screens (7), carriage (2) is inserted in the housing (1) from housing (1) openend, and protective tube (3) two conducting end are clamped by two intermediate plates (5).Utilizing two wiring holes (4) that the utility model is connected during use gets final product in the power circuit.
For carriage (2) can firmly be inserted in the housing (1), translot shape screens (7) both sides on carriage (2) are provided with rubber-like restriction protrusion (8), after carriage (2) is inserted in the housing (1), because the outside tension force effect of restriction protrusion (8) tightly is enclosed within the housing (1) carriage (2).
In order to make wiring hole (4) safety and reliability, wiring hole (4) is a stud bump, and it is wrapped with insulating material.
For the utility model can be fixed in switch or the socket panel easily, be provided with the retainer ring of using for screw (9) in two outsides of housing (1).
Also overlap on the loam cake (6) of this external the utility model carriage (2) and be stamped sheathing (10), sheathing (10) both can play protection carriage (2), also can play decoration function.
Claims (4)
1, a kind of circuit safeties, by housing (1), carriage (2), protective tube parts such as (3) are formed, it is characterized in that housing (1) is an insulation oblong cavity, the one end opening, other end sealing, blind end is provided with two wiring holes (4) and terminal screw outward, be fixed with two intermediate plates (5) on the cavity inner sealing end, intermediate plate (5) is connected with wiring hole (4), the translot shape screens (7) that carriage (2) is provided with loam cake (6) and matches with protective tube (3) external form, protective tube (3) is installed in the screens (7), and carriage (2) is inserted in the housing (1) from housing (1) openend, and protective tube (3) two ends are clamped by two intermediate plates (5).
2, circuit safeties as claimed in claim 1 is characterized in that being provided with restriction protrusion (8) in screens (7) both sides of carriage (2), and wiring hole (4) is a stud bump, and it is wrapped with insulating material.
