Abstract
The utility model relates to a condenser upper cover belongs to capacitor bank spare field, the motor end cap comprises a cover body, lid wiring hole, lid oil filler point have been seted up on the lid, the figure in lid wiring hole is more than two or two, the symmetry sets up between the lid wiring hole, one side that the lid is close to the condenser inside is provided with the annular groove, the utility model discloses still relate to one kind rather than complex explosion -proof block. The mutual block of ring -shaped convex part installation on annular groove that this technical scheme passes through the condenser upper cover and the explosion -proof block realizes capacitor bank dress in -process and realizes quick alignment, and wherein the annular groove can form through the punching press, and production is convenient, and the plane laminating in prior art is compared to this kind of recess cooperation structure, can increase substantially production efficiency, effectively reduces because the product defects that condenser upper cover and explosion -proof block installation dislocation led to the fact the practical value who has profitable technological effect and showing.
Description
Technical field
The utility model relates to a kind of upper capacitor cover, and the utility model also relates to a kind of explosion-proof block be mated, and belongs to capacitor assembly field.
Background technology
Current capacitor is widely used in fields such as power electronics, communications service and rail transport, along with the development of scientific and technological level, film capacitor relies on its good electrician's performance and high reliability, becomes to promote above-mentioned industry field and to update indispensable electronic component.At present; capacitor is in component mounting process; usually through rivet, electrode, copper foil, explosion-proof block and upper capacitor cover are coupled together; wherein explosion-proof block upper surface of the prior art is smooth structure; itself and upper capacitor cover rely on the fixing compact of rivet to fit; due to explosion-proof block and upper capacitor cover being all reserved with wiring hole; thus in anabolic process, usually can there is the problem that can not accurately aim at both; thus cause capacitor corresponding construction to misplace, there is electric power hidden danger in actual use.
Summary of the invention
For solving problems of the prior art, the utility model provides a kind of upper capacitor cover, and concrete technical scheme is as follows:
A kind of upper capacitor cover, comprise lid, described lid offers lid wiring hole, lid oil filler point, the number of described lid wiring hole is two or more, be symmetrical arranged between described lid wiring hole, described lid is provided with annular groove near the side of capacitor internal.
As the improvement of technique scheme, described lid is provided with pitting near the side of capacitor internal.
The utility model additionally provides the explosion-proof block that a kind of and above-mentioned upper capacitor cover adapts, comprise block, described block is symmetrically arranged with the block wiring hole that two or more run through block, described block edge offers block oil filler point, side near upper capacitor cover on described block is provided with annular protrusion, and described annular protrusion and annular groove cooperatively interact.
As the improvement of technique scheme, described block is provided with point-like protuberance near the side of upper capacitor cover, and described point-like protuberance and pitting cooperatively interact.
Technique scheme engages installation by the annular groove of upper capacitor cover mutually with the annular protrusion on explosion-proof block, realize realizing fast aligning in Capacitor banks process of assembling, its annular recess can be formed by punching press, convenient for production, this recessinterengaging means is fitted compared to prior art plane, can production efficiency be increased substantially, effectively reduce because upper capacitor cover and explosion-proof block install the product defects misplacing and cause, there is useful technique effect and significant practical value.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of upper capacitor cover of the utility model;
Fig. 2 is the structural representation of explosion-proof block in the utility model.
Embodiment
As shown in Figure 1, the utility model provides a kind of upper capacitor cover, comprise lid 10, described lid offers lid wiring hole 11, lid oil filler point 12, the number of described lid wiring hole 11 is two or more, be symmetrical arranged between described lid wiring hole 11, described lid 10 is provided with annular groove 13 near the side of capacitor internal, this upper capacitor cover is combined with explosion-proof block as shown in Figure 2, this explosion-proof block comprises block 20, described block 20 is symmetrically arranged with the block wiring hole 21 that two or more run through block, described block 20 edge offers block oil filler point 22, it is characterized in that, side near upper capacitor cover on described block 20 is provided with annular protrusion 23, described annular protrusion 23 cooperatively interacts with annular groove 13.
Technique scheme engages installation by the annular groove 13 of upper capacitor cover mutually with the annular protrusion 23 on explosion-proof block, realize realizing fast aligning in Capacitor banks process of assembling, its annular recess 13 can be formed by punching press, convenient for production, this recessinterengaging means is fitted compared to prior art plane, can production efficiency be increased substantially, effectively reduce because upper capacitor cover and explosion-proof block install the product defects misplacing and cause.
Further, lid 10 is provided with pitting 14 near the side of capacitor internal, accordingly, block 20 is provided with point-like protuberance 24 near the side of upper capacitor cover, described point-like protuberance 24 cooperatively interacts with pitting 14, the reason of this structural design is, wiring hole 11 symmetric design on upper capacitor cover, the structure that independent employing annular groove 13 and annular protrusion 23 cooperatively interact can realize aiming between upper capacitor cover with explosion-proof block center, but still need manual-alignment between lid wiring hole 11 and block wiring hole 21, and set up on this basis pitting structure can cover on the capacitor to fit with explosion-proof block after relative rotate after, after point-like protuberance 24 and pitting 14 are fitted, namely upper capacitor cover and explosion-proof block realize aiming at of wiring hole, convenient and practical.
