Problems solved by technology
However, the contact rings in the prior art are usually integral structures. When made of high-conductivity materials, they have excellent electrical conductivity and can increase the load capacity, but their elasticity is poor, which affects the connection between the connecting terminals and the electrical conductivity. The reliability of the contact between the shafts; when made of high elastic materials, this contact ring can provide better reaction force and achieve excellent contact reliability between the connecting terminal and the conductive shaft, but its conductivity Weak, it is difficult to meet the load requirements, which affects the use of the product

The invention discloses a contact part of a bypass switch. The contact part comprises a connecting terminal, a contact ring and a conductive shaft, wherein the contact ring is arranged between the connecting terminal and the conductive shaft. The contact ring is formed by one supporting tape made of highly elastic material and multiple conductive bars made of highly conductive material. The supporting tape is bent into an annular shape having an opening. The multiple conductive bars are clamped on the supporting tape. Separation of contact conduction and contact pressure is realized by improving the structure of the contact part so that the influence of attenuation of the contact pressure of a force bearing part caused by heating of the load can be effectively reduced, counterforce meeting the certain requirement can be provided to realize the contact reliability of the connecting terminal and the conductive shaft, the excellent conductive performance can also be provided and thus the load capacity can be greatly enhanced.
Description
technical field [0001] The invention relates to the technical field of a bypass switch, in particular to a contact part of a bypass switch. Background technique [0002] A battery bypass switch in the prior art is applied to a battery pack. It is connected in parallel with a single battery and then connected in series in the battery pack. The circuit is cut off to ensure the reliability of the entire battery pack. [0003] This battery bypass switch requires high reliability, long working life, light weight, small size, low contact resistance, and the type of use is one-time use. [0004] This kind of battery bypass switch mainly includes a trigger part and a contact part. The trigger part requires that the mechanism cannot act when locked. After unlocking, it quickly realizes the switching function of first break and then break. After the action is in place, it can maintain a stable state. The contact part usually includes a conductive shaft, When the contact ring and the...
