Abstract
The utility model belongs to the field of capacitors, and specifically relates to an epoxy resin perfusion capacitor which comprises a housing and an end cap provided with a terminal. The epoxy resin perfusion capacitor is characterized in that a plurality of cores, each of which is individually arranged in one plastic casing, and an epoxy resin layer is perfused between each core and matching plastic casing. A vermiculite layer is filled between the plastic casings and the plastic casing and the housing, and the leading-out wires of the cores pass through the epoxy resin layer and extend to the external of the plastic casings to connect with the terminal on the end cap. The epoxy resin perfusion capacitor is convenient for processing, low in cost, excellent in heat radiation effect of the product, stable in performance and safe in operation.
Description
Technical field
The utility model belongs to capacitor area, is specifically related to a kind of epoxy resin perfusion capacitor.
Background technology
The existing dry-type capacitor with epoxy resin perfusion mostly is fuse is connected according to certain cabling mode with wire, is positioned in shell, then to direct infusion epoxy resin in shell after arranging.This reperfusion mode extraction cable is difficult to fix, and product appearance is not attractive in appearance; Because shell space is larger, often need infusion epoxy resin several times in addition, increased operating procedure complexity; After form, interiors of products becomes an integral body, and element produces heat while normally moving is difficult to distribute, and forms hidden danger.
Utility model content
The purpose of this utility model is to solve the dry-type capacitor of prior art epoxy resin perfusion, its fuse perfusion is structure as a whole, heat is difficult to distribute, hold flimsy defect, provide a kind of technique simple, be convenient to quality control, save material, product good heat dissipation effect, stable performance, the epoxy resin perfusion capacitor of security of operation.
The utility model is achieved by the following technical solution:
It is a kind of epoxy resin perfusion capacitor, comprise shell, end cap, end cap is provided with terminal, it is characterized in that being provided with in shell a plurality of fuses, each fuse is placed on separately one and moulds in shell, and each fuse and its supporting moulding between shell are perfused with epoxy resin layer, mould between shell and mould shell and shell between be filled with vermiculite layers, the lead-out wire of fuse is through epoxy resin layer, extends to mould that shell is outside to be connected with the terminal on end cap.
As a preferred version of the present utility model: be provided with hot fuse in fuse, the lead-out wire of hot fuse, through epoxy resin layer, extends to and moulds shell outside.
Principle of the present utility model is as follows:
Fuse is placed in moulds shell, and it is cylindrical moulding shell, and internal space ratio fuse a little more greatly; Fuse is internally connected with hot fuse, and the BVR line of fuse bottom end face welding passes after being placed in the hot fuse of fuse, then fuse is placed in and is moulded in shell; Then to moulding shell infusion epoxy resin, mould shell and fuse and become one with epoxy resin perfusion; After hardening of resin moulding, according to the fuse of product requirement handle, according to cabling mode, couple together, lead-out wire is connected on terminal; On end cap, be furnished with terminal, shell is rectangle, between shell and fuse, fills vermiculite, and housing and top cover are reinforced with rivet.
The utlity model has easy to process, cost is low, product good heat dissipation effect, stable performance, the advantage of security of operation.The independent infusion epoxy resin of each fuse of the present utility model, because single perfusion volume is little, operates convenient and easy, and quality control is also easier, has also saved material simultaneously.In production process, can arrange personnel by operation break-down, save manpower.Single fuse perfusion volume is little, and radiating effect is better, coordinates the vermiculite layers of filling in shell, substantially there will not be capacitor operation to produce the situation that dissipation of heat is not gone out.Safety and stability during this capacitor operation, can not save bit by bit excessive power even if break down yet, and can guarantee site safety.After epoxy resin coagulation forming, lead-out wire is welded on terminal, with regard to having solved the lead-out wire of traditional approach, is difficult to fixation problem like this.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 moulds the cross-sectional view of shell inside in Fig. 1.
As shown in FIG.: 1. terminal; 2. shell; 3. lead-out wire; 4. mould shell; 5. vermiculite layers; 6. epoxy resin layer; 7. fuse; 8. hot fuse.
Embodiment
As shown in Figure 1 and Figure 2: shell 2 upper ends of rectangle are provided with end cap, end cap is provided with terminal 1, in shell 2, be provided with a plurality of columniform shells 4 of moulding, mould between shell 4 and mould shell 4 and shell 2 between be filled with vermiculite layers 5, each is moulded shell 4 inside and is provided with a fuse 7, moulds shell 4 and is a bit larger tham fuse 7, pour into epoxy resin layer 6 in fuse 7 and the gap of moulding between shell 4, the lead-out wire 3 of fuse 7 and internal heat fuse 8 thereof, through epoxy resin layer 6, extends to and moulds outside shell 4, is connected with terminal 1.
The independent infusion epoxy resin of each fuse 7 of the present utility model, because single perfusion volume is little, operates convenient and easy, and quality control is also easier, has also saved material simultaneously.
Single fuse perfusion volume is little, and radiating effect is better, coordinates the vermiculite layers of filling in shell, substantially there will not be capacitor operation to produce the situation that dissipation of heat is not gone out.Safety and stability during this capacitor operation, can not save bit by bit excessive power even if break down yet, and can guarantee site safety.
