According to the utility model, as the insulating head in threaded assembly with the pole and the insulating sleeve covered outside the pole nut, the wiring terminal and other conductive parts are adopted, potential safety hazards such as short-circuit firing and the like, caused by the reason that the electrode or the nut, the wiring terminal and other conductive parts, which are fastened on the electrode, are touched during operation, are avoided, safety in operation is ensured, the assembly and disassembly are convenient and fast, the operating efficiency is high and reusability is permitted.

Description

A kind of lithium ion single battery screw thread pole protective cap

Technical field

The utility model belongs to lithium ion single battery electrical property experimental technique field, especially relates to a kind of lithium ion single battery screw thread pole protective cap.

Background technology

The lithium ion single battery short circuit spark phenomenon occurs for making exposed the two poles of the earth pole outside when change into, electric performance test etc. tested at present, uses adhesive tape to coat pole usually and insulate.Bring potential safety hazard owing to running into electrode easily or being fastened on conductive features such as nut on the electrode, binding post during operation; And the fastness of adhesive tape is poor, the operating time is grown and causes inefficiency when loading and unloading adhesive tape, and adhesive tape can only once use and cause waste.

Summary of the invention

The utility model for solve the technical problem that exists in the known technology provide firm, easy to loading and unloading quick, the high efficiency of a kind of safety, can reusable a kind of lithium ion single battery screw thread pole protective cap.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:

A kind of lithium ion single battery screw thread pole protective cap comprises that having externally threaded pole, an end on the lithium ion single battery is the binding post of stiff end for the exit other end; Said pole is fastened on the boss of battery through the pole nut; The stiff end that is enclosed within the binding post on the pole is fastened on pole nut upper end through the binding post nut; Be characterized in: screw thread is fixed with insulation head and insulating case on the said pole; Said insulating case is enclosed within stiff end, pole nut and the part boss outside of binding post nut, binding post, and the lower end of insulating case is shaped at the stiff end of binding post and the under shed between the exit.

The utility model can also adopt following technical characterictic:

A said insulation outside is shaped on an axial notch; Said insulating case is the inversion tubbiness that the upper end has aperture, and the insulating case upper end is shaped on criss-cross four upper sheds, and insulating case upper end active card is loaded in the groove of insulation head.

Said insulation head and insulating case are plastic material.

Advantage and the good effect that the utlity model has are:

1, the utility model is owing to adopted with the insulation head of pole screw thread loading and unloading and be covered in the insulating case of conductive features outsides such as pole top nut, binding post; Run into electrode when having stopped operation or be fastened on conductive features such as nut on the electrode, binding post and cause potential safety hazard such as short circuit sparking; Guaranteed work safety, and quick, high efficiency easy to loading and unloading, can reuse.

2, the utility model adopts four upper sheds of insulating case to realize that the insulating case active card is loaded in the groove of insulation head; Insulating case can not rotate with the screw-in action of insulation head, has further protected the firm and stable of conductive features such as being fastened on electrode top nut, binding post.

3, the utility model is employed in and is shaped under shed on the insulating case, has avoided further having guaranteed safe affected with being fastened on the problem that conductive features such as nut on the electrode, binding post cover.

Description of drawings

Fig. 1 is that the utility model lithium ion single battery screw thread pole protective cap master looks sketch map;

Fig. 2 is an A-A cross-sectional schematic among Fig. 1.

Label among the figure is respectively: 1-lithium ion single battery; The 2-under shed; The 3-boss; The 4-insulating case; 5-pole nut; The 6-binding post; 7-binding post nut; The 8-upper shed; The 9-groove; The 10-pole; The 11-head that insulate.

Embodiment

For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:

With reference to accompanying drawing 1-Fig. 2: a kind of lithium ion single battery screw thread pole protective cap comprises that having externally threaded pole, an end on the lithium ion single battery is the binding post of stiff end for the exit other end; Said pole is fastened on the boss of battery through the pole nut, and the stiff end that is enclosed within the binding post on the pole is fastened on pole nut upper end through the binding post nut.
