Embodiment
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the invention provides a kind of new waterproof noinductive capacitor, comprise housing 10, upper capacitor cover 20, described upper capacitor cover 20 is provided with the rivet 40 running through lid, the insulating barrier 22 that described upper capacitor cover 20 comprises plate body 21 and is injection-moulded on plate body 21, described plate body 21 is provided with plate body hole 211, described insulating barrier 22 extends to form the plate body hole lining 223 of constraint rivet 40 in plate body hole 211, and lining 223 lower end, described plate body hole forms plate body hole lining flange 224.Technique scheme, by being kept apart in rivet 40 and plate body hole 211 with the plate body hole lining 223 of insulating barrier 22 one, forms the bed course that has buffering transitional function, and after avoiding capacitor Long-Time Service, rivet 40 and upper capacitor cover 20 deformation occurs misplace; Fit tightly below plate body hole lining flange 224 simultaneously below plate body hole lining 223 and plate body 21, thus improve the fastness of plate body 21 and insulating barrier 22 combination.
Further, plate body 21 is also provided with explosionproof hole 212, described insulating barrier 22 is provided with the explosionproof hole lining 225 of hollow near the position of explosionproof hole 212, described explosionproof hole lining 225 lower end forms explosionproof hole lining flange 226, why adopt the explosionproof hole lining 225 of hollow structure, it is the structure in order to adapt to explosionproof hole 212, if explosionproof hole lining 225 adopts entity structure, be unfavorable for when capacitor internal pressure raises suddenly, capacitor internal air-flow is derived from explosionproof hole 212, and the effect of explosionproof hole lining flange 226 improves the bond strength of insulating barrier 22 at explosionproof hole 212.
Further, insulating barrier 22 edge extends to form " L " type bound edge 222 downwards, described bound edge 222 pairs of plate bodys 21 are completely coated near the edge of housing 10, the effect of bound edge 222 forms barriers between plate body 21 and housing 10, avoiding plate body 21 in capacitor use procedure that deformation occurs causes plate body 21 and housing 10 junction to occur gap, cause capacitor electrolyte inside to leak, cause electric power system fault.
Further, as shown in Figure 5, the position that housing 10 contacts with upper capacitor cover 20 is provided with groove 11, and the bound edge 222 phase coadaptation of described groove 11 and insulating barrier 22, the described side of groove 11 above upper capacitor cover 20 is provided with housing flange 12.Said structure by groove 11 and the coadaptation of bound edge 222 phase, achieves fitting tightly of housing 10 and upper capacitor cover 20, while housing flange 12 structure design, enhance the firm grip of housing 10 pairs of upper capacitor covers 20.
In the above-described embodiments, the both sides that rivet 40 covers 20 are on the capacitor fixedly connected with ring connection terminal 30 and aluminum annular-shaped paillon foil 60 respectively, described ring connection terminal 30 extends to form join on skew terminal 31 to side, described aluminum annular-shaped paillon foil 60 extends to form electrode terminal 61 to side, in this technical scheme, why ring connection terminal 30 and aluminum annular-shaped paillon foil 60 are adopted annular design, in order to fixing with rivet 40 while, realize the compression to insulating barrier 22, guarantee the fastness connected.
Further, electrode terminal 61 deviates from the join on skew terminal 31 that same rivet 40 connects, the reason of such design is that aluminum annular-shaped paillon foil 60 plays a part connection rivet 40 and electrode, and the effect of join on skew terminal 31 is drawn by wire, therefore aluminum annular-shaped paillon foil 60 and the join domain of electrode can be set to the side away from the join on skew terminal 31 be connected with same rivet 50, thus realize the wire lead-out area in capacitor use procedure above upper capacitor cover 20 and the Electrode connection region below cover plate 20 affects minimum each other.
Further, join on skew terminal 31 both sides respectively on extend to form baffle plate 32, baffle plate 32 and the join on skew terminal 31 of described both sides enclose wire lead-out area jointly, join on skew terminal 31 has been threaded terminal screw 50, during use, one end of wire is fixed on join on skew terminal 31 by terminal screw 50, the other end is drawn and is connected with other electric power components and parts, and the design of baffle plate 32 is isolated wire lead-out area in this structure, avoid influencing each other between different join on skew terminal 31.
