Problems solved by technology
[0002] The printed board connectors of existing communication equipment usually use press-fit terminations to meet the requirements of double-panel insertion and high density. Press-fit terminals are generally released by opening slender oval holes on the contacts. Press-fit deformation, such as Chinese patent 97119231.6, U.S. patent 90111791.1, 9145408, 6305949B1, 0054225 A1, etc., the structures described in these patents all have the disadvantages of being unable to achieve multiple press-fitting, difficult mold opening, high cost, and punching slender oval holes Structural damage and other issues
With the development of miniaturization of high-speed PCB connectors and the further improvement of their installation density, the slender elliptical hole will become smaller and smaller, which will bring higher and higher mold costs, and even the method that is difficult to use mold punching will appear. to achieve the problem

Embodiment Construction
[0012] figure 1 It is the elastic press-fit terminal of the preferred embodiment of the present invention. It is used for the tail end part of the leaf spring contact of the PCB connector. In order to focus on describing the elastic press-fit terminal involved in the present invention, we are in figure 1 The mating section and other parts of the contact are omitted.
[0013] The molding process of the elastic press-fit terminal manufactured by the present invention is as follows: firstly, multiple symmetrical bends are formed by stamping, and then 180° bending is performed at the symmetrical bending line 1 to make them overlap symmetrically, and directly form the Straight line guide section 2, inclined line transition section 3, elastic contact section 7 and insulator fixing section 5 structure, elastic contact section 7 is a drum shape protruding to both sides after forming, and a release pressure is provided between the two layers of material of elastic contact section 7 R...

An elastic press-fit terminal used for an electric connector of a printed circuit board adopts a structure which is directly formed by punching, oppositely folding and forming belt materials and comprises a rectilinear guiding section, an oblique line-shaped transition section, an elastic contact section and an insulator fixing section which are respectively composed of two layers of material. The elastic contact section is in the shape of a drum protruding to both sides thereof; a reserved space for releasing the press fit deformation is formed between the two layers of material of the elastic contact section. The invention improves the reliability and the operability of the connection of the press-fit terminal, satisfies the requirements of small-scale and high-density installation, is processed conveniently, and realizes repeated insertion.
Description
1. Technical field [0001] The invention relates to a connector press-fit terminal, in particular to an elastic press-fit terminal for a printed board connector. 2. Background technology [0002] The printed board connectors of existing communication equipment usually use press-fit terminations to meet the requirements of double-panel insertion and high density. Press-fit terminals are generally released by opening slender oval holes on the contacts. Press-fit deformation, such as Chinese patent 97119231.6, U.S. patent 90111791.1, 9145408, 6305949B1, 0054225 A1, etc., the structures described in these patents all have the disadvantages of being unable to achieve multiple press-fitting, difficult mold opening, high cost, and punching slender oval holes Structural damage and other problems. With the development of miniaturization of high-speed PCB connectors and the further improvement of their installation density, the slender elliptical hole will become smaller and smaller, ...
