The press-in type welding-free conductive terminal forms an elastic through hole on the plug part, so that the terminal can be easily pressed in the connection process, but the terminal is easy to deform, and the conductive reliability is reduced. To meet the requirement of electrical performance, the patent improves the electrical conductivity by plating copper layers and gold layers on the surfaces of the brass terminals in sequence, which undoubtedly increases the production cost of the terminals greatly.
Chinese patent publication No. CN203674429U discloses an impervious welding-free eagle eye terminal, which comprises a terminal main body, wherein one side of the terminal main body is provided with an inward concave elongated groove, the cross section of the elongated groove is in an inverted trapezoid shape, the depth of the elongated groove is greater than one half of the thickness of the terminal main body, and the two sides of the middle part of the terminal main body are arranged into a plane shape. In the non-through type welding-free hawk-eye terminal, a groove which does not penetrate through the terminal is adopted on the terminal main body, although the holding force after the terminal is connected can be increased, the terminal needs larger pressure welding force when being inserted into an electronic device, and the electronic device is easily damaged.
