Embodiment

[0023] Example: such as figure 1 As shown, a pin terminal for press-fit connection, which includes a mounting butt joint part 11, a bent connection part 12 and a press-fit part 10 whose tail end is press-fit connected with the circuit board opening 3.

[0024] The installation docking part 11 is provided with a docking end 110 for docking, a barb 111 for fixing the pin terminal 1 in the base, and an anti-rotation structure straight line 112. The tail end press-fitting part 10 includes: a guide part 101, The holding part 102 matched with the hole 3 of the circuit board. The guide part 101 ensures that the holding part 102 can be smoothly pressed into the opening 3 of the circuit board.

[0025] Such as figure 2 , image 3 , Figure 5 As shown, the holding part 102 includes two grooves 1023 and four sidewalls 1021 extending from the root to the distal end. Between the two grooves is a section of thin wall with a slope, that is, the middle inclined beam 1022 . The middle sl...

Abstract

The invention discloses a contact pin terminal for press-fit connection, comprising an installation butt-joint part (11) and a press-fit part (10), wherein the press-fit part (10) comprises a guiding part (101) and a holding part (102) matched with a circuit board open pore (3), two sides of the holding part (102) are respectively provided with a groove (1023) extending along the axial direction of the holding part (102), the bottoms of the grooves (1023) incline, a thin-wall type intermediate oblique beam (1022) with gradient is formed between the two grooves (1023) which are symmetrically distributed relative to the intermediate oblique beam (1022), and the two grooves (1023) form four side walls (1021), which can deform along the edge of the circuit board open pore (3) during press fit and are tightly appressed to the inner wall of the open pore (3). The contact pin terminal has a simple structure, is durable, reliable, resistant to shocks and impacts, and convenient and rapid for press fit; and in addition, the contact pin terminal is formed with a machining method and has the advantages of strong current bearing capacity, high mechanical strength, wide adaptation rang, and ideal press-fit force and holding power, and the materials can be selected flexibly.

Description

technical field [0001] The invention relates to a pin terminal for press-fit connection, and the connection structure is mainly used for the connection between a circuit board and other electrical components. Background technique [0002] Press-fit terminals are widely used for connection between circuit boards and other electrical components, and can obtain good mechanical and electrical properties. When the terminal is pressed into the opening on the printed board, its main feature is that it can complete the assembly of electrical components without soldering and other steps. Patents such as CN2462573Y, CN2618322Y, and CN2629251Y all demonstrate this type of terminal structure. The nominal size of the crimping part is larger than the opening size of the printed board, but the press-fit part can be deformed. Under the extrusion of the opening, the material is deformed, making the contact area elastically contacting, ensuring a stable electrical and mechanical connection. ...
