Moreover, the isolation space is defined between the electrode tab protruding end and the battery cell, which further prevents the electrode tab connector from pressing and damaging the battery cell, and improves yield rate. The current collecting plate is applied in the battery, the battery module and the battery pack. Therefore, the electrode tab connector is prevented from pressing and damaging the battery cell during encapsulating process, which improves yield rate.

This utility model relates to the field of material forming technology, specifically to a dry-pressed ceramic plate for metal powder forming. It has a first forming concave-convex portion with multiple draft angles. At least one draft angle of the first forming concave-convex portion is designated as the first draft angle. The angle between the first draft angle and other draft angles is defined as the draft angle, which can be a chamfered or rounded structure. This utility model reduces the bonding area between the dry-pressing mold and the ceramic plate at the draft angle by setting the draft angle to a chamfered or rounded structure, thereby reducing the bonding force and demolding difficulty. It can directly form ceramic plates with small draft angles (e.g., less than 15°) without further machining, reducing costs and improving efficiency. It solves the problem that existing dry-pressed ceramic plates cannot be directly formed with small draft angles and can also serve as a standard mold structure for forming various types of dry-pressed ceramic plates in subsequent designs.

The utility model discloses an optical film convenient to strip, relates to the field of optical films, and aims to solve the problems that in the prior art, after the optical film is produced, protective films are usually attached to two surfaces for protection, pull pieces are fixed on the protective films, so that the protective films can be stripped conveniently, but when the protective films are stripped through pull strips, the pull pieces cannot be attached to the protective films. And the protective film is easy to damage due to overlarge tension. A movable groove is formed in the side end face of the interior of the protection frame, a plurality of guide columns are fixedly arranged in the movable groove, a hard transparent protection film is connected to the interior of the protection frame, a plurality of adhesion columns are arranged at the lower end of the hard transparent protection film in an array mode, and an optical film is jointly adhered to the lower ends of the adhesion columns. A bonding groove is formed in the lower end face of the protection frame, a bonding glue layer is fixedly arranged at the upper end in the bonding groove, a lower protection film is connected into the bonding groove, and L-shaped buckling and pulling pieces are fixedly connected to the middles of the two sides of the lower end face of the lower protection film.

The utility model relates to the technical field of display, in particular to a connecting adhesive tape and a display device. The connecting adhesive tape provided by the utility model is used for connecting a backlight module and a display panel, the connecting adhesive tape comprises foam rubber, an inflation cavity is formed in the foam rubber, an inflation hole communicated with the inflation cavity is further formed in the foam rubber, and a plurality of air outlet holes communicated with the inflation cavity are formed in at least one side of the foam rubber in an array mode. According to the connecting adhesive tape provided by the utility model, when a backlight module and a display panel which are adhered and fixed by the connecting adhesive tape need to be detached, air is inflated into the inflating cavity of the foam adhesive through the inflating hole, so that the air can be discharged through the air outlet hole, and the air discharged from the air outlet hole impacts a bonding surface between the backlight module or the display panel and the foam adhesive; and the bonding area between the backlight module or the display panel and the foam rubber is reduced, so that the backlight module and the display panel are conveniently detached, and the backlight module and the display panel are prevented from being detached and damaged.
