Embodiment

By reference to the accompanying drawings the present invention is described in further detail below by embodiment.

Embodiment mono-:

As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of embodiment of the present utility model directly goes out terminal battery cap fastener, comprise securing member 1, the present embodiment is preferably the hollow cavity that securing member 1 is annular, hollow cavity internal diameter is greater than and directly goes out terminal 2 external diameters, and hollow cavity is both ends open, on the inwall of hollow cavity, be provided with the projection 11 of 3, projection 11 is on the bus that strip is attached to hollow cavity inwall, cross section is square, being beneficial to processing and stressed shovel scrapes, article 3, projection 11 is around the center line setting of hollow cavity, 11 angles of being separated by of every two adjacent protrusion are consistent.The inwall of projection 11 outers and hollow cavity surrounds the shovel that is less than directly to go out terminal external diameter and scrapes cavity, and the interior circular diameter that for example protruding outer surrounds is less than the external diameter 1～4mm that directly goes out terminal 2, shovels to meet the lead of scraping lead terminal superficial layer 1～2mm thickness.

One end of securing member 1 is provided with indent circle 12, and its internal diameter is greater than internal radius, and is greater than the external diameter 1～3mm of plumbous cover 3, and its degree of depth is set to 3～8mm.Indent circle 12 arranges larger internal diameter, is placed on plumbous cover 3 upper ends, the plumbous cover of protection when fastening.The openend of indent circle 12 is provided with chamfering 13, can effectively guide securing member 1 to be placed on lead and put, and can prevent unnecessary scuffing simultaneously.

When fastening, directly go out under the prerequisite of terminal 2 main functionalities not destroying machine, shovel and scrape the lead that directly goes out terminal 2 outer walls from top to bottom by three projections 11 on securing member 11 inwalls, make directly to go out terminal and extend outward three salient points 21,, these three salient points 21 are stuck on the lead cover 4 of battery cover 3, three salient points 21 are an entirety with directly going out terminal 2, so salient point 21 has limited the degree of freedom of plumbous cover 4 vertical direction, and plumbous cover 3 is to be embedded in battery cover 3, has prevented upwarping of battery cover 3.Securing member 11 completes shovel when scraping, and the indent circle 12 of plumbous cover 4 upper end fasteners 11 covers, and prevents that securing member 1 shovel from scraping directly to go out after terminal 2, and plumbous cover 4 is subject to top-down active force and surrounding is opened, so that follow-up welding operation.

Embodiment bis-:

As shown in Figure 4 and Figure 5, the another kind of embodiment of the present embodiment directly goes out terminal battery cap fastener, comprises securing member 1 and installed part 5, and wherein securing member 1 can adopt securing member as shown in embodiment mono-.

Installed part 5 is preferably cylindrical, and one end and securing member 1 do not arrange one end (being the upper end of securing member 1 in Fig. 4) welding of indent circle 12, and connected mode in other embodiments also can be for being threaded.The link of installed part 5 is provided with and securing member 1 inner circle cavity of the same size, for accommodating may be through securing member 1 when fastening directly go out terminal 2.

The Main Function that installed part 5 is welded on securing member 1 is scraped fastening and extracts for convenience of the shovel of securing member 1, shovel is scraped when fastening, only need beat installed part 5 tops with rubber hammer, just can complete shovel and scrape, having improved that securing member 1 scrapes at shovel is the inconvenient problem of scraping of shoveling of beaing while directly going out terminal 2 through securing member 1.As a long handle, conveniently take out securing member 1 simultaneously.

Embodiment tri-:

As shown in Figure 5, the present embodiment provides a kind of lead acid accumulator, comprise and directly go out terminal 2, battery cover 3 and plumbous cover 4, directly going out terminal 2 stretches out from battery cover 3, plumbous cover 4 is embedded in battery cover 3, and be set in and directly go out outside terminal 2, what also comprise above-described embodiment directly goes out terminal battery cap fastener, wherein securing member 1 is set in and directly goes out on terminal 2, projection 11 shovels on securing member 1 are scraped the lead that directly goes out terminal 2 outer surfaces, form corresponding salient point 21 directly going out terminal 2 lower end outer surfaces, salient point 21 is stuck between the lower end and plumbous cover 4 upper ends of securing member 1, limited the degree of freedom of the vertical direction of plumbous cover 4 together with directly going out terminal 2, prevent upwarping of plumbous cover 4, plumbous cover 4 is inlayed with battery cover 3 again, so salient point 21 can prevent upwarping of whole battery cover 3, facilitate the follow-up welding that directly goes out terminal 2, alleviate the burden of employee's operation.

Above content is in conjunction with concrete execution mode further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace.
