Abstract

The utility model discloses an accumulator end cover, which solves the problem of the poor sealing performance caused by the property difference of different kinds of materials when sealing the accumulator through imbedding a ring of metal jacket on the inner diameter of the hole extended by the electrode pole of the accumulator of the common Accumulator end cover. The utility model can be extensively used in various industries of producing the accumulator, particularly the sealing industry relating to the lead-acid accumulator.

Description

A kind of storage battery end cap

The utility model belongs to the field of the structure of storage battery end cap.

The existing storage battery end cap adopts the injection moulding process manufacturing, on end cap, be reserved with the circular hole that stretches out for the battery electrode column, during sealing, between lead terminal post and plastic end cover, add annular rubber ring, recharge epoxy resin, adopt this plastic end cover often because the processing of material and the difference on the material character cause sealing property to increase with the operating time and descends rapidly, cause the seepage of battery liquid to take place.

The purpose of this utility model provides a kind of pretreated storage battery end cap, when making sealed cell electrode column and end cap, guarantees that same material engages.

For solving above-mentioned task, the technical solution adopted in the utility model is as follows:

A kind of storage battery end cap has on the storage battery end cap and is used for the hole that the battery electrode post stretches out the storage battery end cap, and the internal diameter in hole also is embedded with metallic sheath on end cap, and the endoporus that can hold the battery electrode post is arranged in the middle of this metallic sheath.

The general employing of above-mentioned metallic sheath processes with the lead alloy of battery electrode post same material.

For ease of the wiring between the battery terminal, above-mentioned metal is with a protruding end, has the hole of being convenient to wiring on the protruding end.

After adopting the above-mentioned end cap that metallic sheath is installed, during the sealed cell electrode column, between metallic sheath and metal battery electrode, adopt method welding such as TIG, write exhausted because the consequence of poor sealing performance when same material engages obtains excellent sealability.

Below in conjunction with paying figure the utility model is described in further detail.

Fig. 1 is a storage battery end cap partial top view.

Fig. 2 is the cutaway view of Fig. 1 along AA ' line.

Fig. 3 is the partial view of the protruding end of metallic sheath among Fig. 2 along the B direction.

Fig. 4 be among Fig. 2 metallic sheath along the vertical view of C direction.

In the storage battery end cap partial top view shown in Figure 1, end cap 1 original hole 5 of stretching out for the battery electrode column embeds metallic sheath 2, in the present embodiment, metallic sheath 2 has adopted with the lead alloy of battery electrode post same material and has made, have the hole 3 that can hold the battery electrode post at lead alloy cover middle part, side at lead alloy cover is processed with a protruding end 4, and this protruding end 4 is convenient to being connected of connection between the battery electrode or power line and battery electrode as binding post.

Figure 2 shows that the cutaway view of Fig. 1 along AA ' line.The lead alloy cover 2 general injection moulding process that adopt embed in the end cap 1, lead alloy cover middle part is processed with the hole 3 that can hold the battery electrode post, overlap 2 one sides at alloy and be processed with protruding end 4, be processed with the hole 6 of being convenient to wiring or connecting other electrode on the protruding end 4, the side that the lead alloy cover embeds end cap is processed with the raised tooth 7 that can increase with end cap contact-making surface and adhesive force.

Figure 3 shows that the partial view of Fig. 2 along the B direction, promptly alloy overlaps protruding end elevation view, is circular port at protruding end wiring hole that open at 4 middle parts 6.

Fig. 2 shown in Figure 4 is along the view of C direction, and wherein 2 is the lead alloy cover, 3 holes for the held battery electrode post of lead alloy cover middle part processing, and 4 overlap the protruding end of being convenient to wiring that a side is processed for lead alloy.

End cap described in the utility model can be widely used in all kinds of storage batterys, particularly as the battery cover of lead acid accumulator.
