The terminal protective sheath is used for the protection to the battery terminal, and present terminal protective sheath presents the cap form mostly, and the upper shield is on the terminal of battery during the use, and conventional terminal protective sheath is only connected by the terminal contact of brim of a hat with the battery, and not only drops easily in the transportation by the crushing, makes the terminal lose the protection, and the terminal protective sheath uses the terminal model to design as the basis moreover, and different terminals correspond different terminal protective sheaths, and the commonality is poor.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a terminal sealing protective sheath that battery was used, this terminal sealing protective sheath is very convenient to overlap on the terminal of battery, is difficult to drop, has good suitability to the terminal of the battery of various sizes.

The terminal sealing protective sleeve for the storage battery comprises a battery cover, wherein a binding post is arranged on the top surface of the battery cover, and a threaded hole is formed in the top surface of the binding post. The terminal sealing protective sleeve comprises a cap part used for covering the top of the storage battery terminal, a fixing column arranged on the inner bottom surface of the cap part and used for extending into the threaded hole, the cap part comprises a cap top and a circle of cap brim arranged on the bottom surface of the cap top, and the bottom surface of the cap brim is provided with a foam double-faced adhesive tape used for being adhered to the top surface of the battery cap.

The foam double-sided adhesive tape can be integrally designed and processed with the terminal sealing protective sleeve during processing, the tightness of the battery cover or the uneven surface of the color adhesive tape is improved when the pressure is applied, and moist air or moisture is prevented from entering the battery.

The novel helmet is characterized in that the inner side wall of the helmet brim is provided with vertically distributed elastic sheets, the radial width of each vertical rib is 1/5-1/3 of the radius of the helmet cap, so that a space is reserved around the fixed column, and when the novel helmet is used, the elastic sheets abut against the outer side wall of the terminal tightly, and the novel helmet has the functions of protecting the terminal, preventing the sheath from loosening and relieving the impact force when an external force collides with the terminal.

Preferably, the spring plate is provided with a first chamfer at one side of the opening of the cap part, so that the terminal sealing protective sleeve is easier to mount and is not easy to fall off.

Preferably, the height of the elastic sheet is consistent with that of the cap peak, so that the cap and the terminal are buckled more tightly.

Preferably, the number of the elastic sheets is 4-8 which are uniformly distributed.

The fixing column is surrounded by 2-3 fixing sheets, a gap is formed between every two adjacent fixing sheets, so that the terminal sealing protective sleeve and the terminal can be conveniently positioned and clamped, and when the fixing column is matched with copper cores of the terminals in different sizes, the gap between every two adjacent fixing sheets can be automatically contracted or expanded, so that the terminal sealing protective sleeve has wide applicability.

One end of the fixing piece is fixed with the bottom surface of the cap top, so that the fixing column is stabilized, the storage battery terminal is prevented from being broken by the reinforcing column when being impacted by external force, and the terminal sealing protective sleeve is prevented from falling off.

The surface of fixed column is equipped with horizontal distribution's burr for with terminal copper core screw thread fastening cooperation, prevent that terminal sealing protective sheath is not hard up.

The end part of the fixing column is provided with a second chamfer, so that the terminal sealing protective sleeve is more easily matched with the terminal.

The terminal sealing protective sleeve is made of flexible materials, the flexible materials are PP, ABS and PE, and PP plastic has the advantages of excellent dielectric property, good water resistance, stable chemical property, easy processing and forming and the like, high grabbing strength, compressive strength, hardness and elasticity, and is preferably made of flexible PP materials.

When the terminal sealing protection sleeve is used, the terminal sealing protection sleeve is buckled and pressed on the top of the terminal, and the convex patterns of the terminal sealing protection sleeve fixing column are tightly matched with the terminal copper core threads, so that the terminal sealing protection sleeve is firmer and is not easy to fall off; the existence of the shell fragment between the brim of a hat of terminal sealing protective sheath and the terminal and the cotton double faced adhesive tape of bubble of brim of a hat bottom for it is inseparabler to seal, prevents that external humid air or moisture from entering into inside the battery.

Compared with the prior art, the beneficial effects of the utility model are that:

(1) the utility model discloses a brim of a hat bottom surface be equipped with be used for with battery cover top surface adhesion add man-hour can with the cotton double faced adhesive tape of bubble of battery terminal sealing protective sheath integration, to battery cover or the leakproofness on colour glue unevenness surface when increasing the pressurized, prevent that humid air or moisture from getting into inside the battery

(2) The utility model discloses can conveniently overlap on the terminal of battery, be difficult for droing, can also prevent the emergence of accidents such as battery damping.
