The high low-resistance connection of normal force, and assembling tolerance can be absorbed, thus there is no need to stringent manufacturing tolerances, reduce system
Make cost.Even if in addition, Elastic Contact is caused by the difference movement caused by vibrating, thermally expanding or the cable strain by applying
It can also be kept in the case of load.In particular, application operating mode of the joint connector that is provided of the technical program in vehicles such as automobiles
Under, for example, Vehicular vibration and vehicle local environment temperature change difference it is big, at this time can avoid with installation port shielding connection
Too high in resistance, and the assembling of joint connector is relatively simple, it is time saving and energy saving.
