Thin temperature fuse with cushion layer structure and preparation method thereof

Abstract

The invention relates to a thin temperature fuse with a cushion layer structure and a preparation method thereof. The thin temperature fuse comprises a pair of metal pins, the metal pins are oppositely arranged in a straight line and reserve intervals between two end parts, a lower carrying belt is arranged below the end of each metal pin, the two end parts are connected with a melting core in a welding manner, a fluxing agent is coated on the melting core, an upper carrying belt covers from the upper part, the upper carrying belt and the lower carrying belt form a sealed cavity, the end parts of the metal pins, the melting core and the fluxing agent are sealed inside the sealed cavity, a middle carrying belt is arranged at the middle of the fuse, a cushion layer is arranged at the middle of the middle carrying belt, and the cushion layer is arranged in the interval between the two end parts of the metal pins so as to mutually and transversely block the two end parts and longitudinally block the melting core and the lower carrying belt. The invention efficiently reduces the melting temperature, the fluxing agent is not easy to leak outside, and steps or corners on the metal pins more meet the using requirements.

Description

technical field [0001] The invention relates to an over-temperature protection thin component for electronic products, in particular to a thin thermal fuse suitable for mobile phone batteries, which is a thin thermal fuse with cushion structure and a preparation method thereof. Background technique [0002] In recent years, the communication industry has developed day by day, especially in the aspect of radio communication, the market of mobile phones has been popularized to the point that almost everyone has a mobile phone. The popularity of mobile phones has directly led to the expansion of the market for mobile phone components, especially mobile phone batteries. [0003] However, during the rapid development of the market, quality problems frequently occurred, such as mobile phone batteries all over the world exploding and injuring people, Nokia recalling 46 million batteries made by Panasonic worldwide, etc., which made the safety of mobile phone batteries become the fo...
