Abstract
The utility model relates to a three pole integrated structure base with a protective cover for a low voltage fuse which can be arranged in a low-pressure complete set of the switch device and control device. The structure of the three pole integrated structure base with a protective cover for a low voltage fuse is that two groups of protective covers whose sockets separated in insulation in the integral structure shape are inserted on the socket; both ends of the socket are correspondingly provided with pressing nuts, on which bolts, an elastic pad and a flat pad are respectively provided; an unsaturated polyester glass fiber reinforcement moulding material bottom plate is adopted to be arranged on a base. The advantages of the three pole integrated structure base with a protective cover for a low voltage fuse is that due to the fact that the protective cover is made of the insulating material, and the three poles are conjoined, the three pole integrated structure base with a protective cover for a low voltage fuse has the excellent protect functions such as arc separating function, anti electric shock function, etc. The clamp nut used for wiring connection is firmly fixed on the socket via the extrusion; when the conducting wires are connected, the installation is very convenient; the bottom plate on the base adopts the unsaturated polyester glass fiber reinforcement molding compound material having the good electrical property and sufficient strength, and has the features of flame resistance, light weight, non-perishable break, etc.
Description
Technical field
The utility model relates to the three extremely integrally-built bases of protecting cover on a kind of low-tension fuse that is installed in low-voltage complete switch equipment and the control appliance with band, belong to low-voltage complete switch equipment and control appliance electric elements technical field.
Background technology
Existing fuse base has one pole, and it is with the insulation board of two single structure shapes in addition arc and protection against electric shock that three utmost points, the fuse base of three utmost points are also arranged, and outside conductive components such as its socket, connection bolt all are exposed to, lacks general security performance.And the base plate that has adopts is iron plate, the Heavy Weight poor safety performance.
Summary of the invention
The purpose of this utility model is the defective at above-mentioned existence, proposes to protect with band on the good low-tension fuse of a kind of performance easy to use, safe three extremely integrally-built bases of cover.Technical solution of the present utility model: its structure is to be inserted on the socket with two groups of overall structure shape protective covers that are that the socket insulation is separated, correspondence is equipped with clamp nut on the socket two ends, on clamp nut, be provided with bolt, bullet pad, plain cushion successively, adopt the glass fiber reinforced moulding material base plate of unsaturated polyester to be contained on the base.Advantage of the present utility model: because protective cover is to make with insulating material, and three extremely whole connections, so it has protective effects such as good arc and protection against electric shock; The clamp nut that wiring is used is fixed on the socket firmly by extruding, installs very convenient when connecting lead; Base plate on the base is the glass fiber reinforced unsaturated polyester plastic material that adopts the superior electrical performance and sufficient intensity is arranged, and has characteristics such as fire-retardant, in light weight, non-friable.

Accompanying drawing 4 is right TV structure schematic diagrames of the present utility model
Among the figure 1 is socket, the 2nd, and flower pad, the 3rd, bolt, the 4th, protective cover, the 5th, clamp nut, the 6th, plain cushion, the 7th, bullet pad, the 8th, base plate.
Embodiment
The contrast accompanying drawing, its structure is that the overall structure shape protective cover 4 that is that two groups of socket insulation separate is inserted on the socket 1, correspondence is equipped with clamp nut 5 on socket 1 two ends, on clamp nut 5, be provided with bolt 3, bullet pad 7, plain cushion 6 successively, adopt the glass fiber reinforced moulding material base plate 8 of unsaturated polyester to be contained on the base.
Low-tension fuse three utmost point unsplit bedplates of tape insulation cover mainly are installed in low-voltage complete switch equipment and the control appliance.After base inserts fuse-link, can be in the industrial frequency AC circuit, as the overload of circuit or the usefulness of short circuit.Low-tension fuse three utmost point unsplit bedplates of tape insulation cover, two groups of edge covers mainly play protective effects such as arc and protection against electric shock; The clamp nut 5 that wiring is used is fixed on the socket firmly by extruding, installs very convenient when connecting lead; Base plate on the base is glass fiber reinforced unsaturated polyester plastic (DMC) material that adopts the superior electrical performance and sufficient intensity is arranged, and has characteristics such as fire-retardant, in light weight, non-friable.
