Background
The elastic sheet connector is widely applied to the communication field, and generally comprises a contact part and at least one elastic part, wherein the contact part is connected with the elastic part, and when an external member contacts with the contact part and applies pressure to the contact part, the elastic part deforms and provides elastic force to enable the contact part to be tightly attached to the external member, so that electric connection is realized.
When the elastic part of the existing elastic sheet connector is pressed, the contact point of the elastic sheet connector and the external component is indefinite, namely, the contact point of the elastic sheet connector and the external component can be changed along with the change of the pressure born by the elastic sheet connector, namely, the external component can generate sliding friction with the contact part, so that the service life of the elastic sheet connector can be shortened; in addition, the greater the pressure applied to the spring connector, the longer the sliding friction occurs, that is, the contact portion of the spring connector needs to have a sufficiently large contact area, which increases the volume of the spring connector.
