Problems solved by technology

Due to the change of the processing size, the short fixed part due to the limitation of the structure, and the assembly deviation, etc., the installation part of the elastic contact is not concentric with the base hole, and the cantilever beam has an amplifying effect on the non-concentricity of the fixed part, resulting in elasticity. Large deflection between the contact head and the base hole, resulting in failure of the connector function

Embodiment

[0021] Example: such as figure 2 As shown, the elastic contact piece of the embodiment of the present invention includes a head 1, a tail 3, and a mounting part 2 arranged between the head 1 and the tail 3, and the head 1 is provided with a positioning claw for fixing in the base hole 40 11.

[0022] Such as image 3 As shown, in this embodiment, the positioning claw 11 is opened outwards at the end, and the opening amount is larger than that of the base hole 40 . In this embodiment, the head 1 is provided with two reeds 12 whose ends are inclined to the axis, and the positioning claws 11 are arranged between the two adjacent reeds 12, and the reeds 12 and the positioning claws 11 are evenly distributed over the head. Part 1 on. The two reeds 12 whose ends are slanted toward the axis make the head 1 tilt inward, so that the opening of the contact piece is smaller than the corresponding pin size, ensuring that there is contact pressure with the pin when the pin is inserted,...

Abstract

The invention discloses an elastic contact element with a concentric locating function, which comprises a head region (1), a tail region (3), and an arrangement region (2) arranged between the head region (1) and the tail region (3), wherein the head region (1) is provided with a locating component fixed in a base hole (40); the locating component is a locating detent (11) ends of which expand outwards; the expanding capacity of the locating detent (11) is larger than the hole diameter of the base hole (40); the head region (1) is provided with at least two reeds (12); the ends of the reeds (12) lean towards an axis; the plurality of reeds (12) are evenly distributed; and the locating component is arranged between two adjacent reeds (12). The elastic contact element disclosed by the invention has good concentricity with the base hole (40), and has stable and reliable connection performance. Besides, the coordinating relationship of the arrangement region (2) and a base has small influence on the concentricity.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to an elastic contact piece used in the connector, especially to an elastic contact piece installed in a base hole and required to be concentric with it. Background technique [0002] Generally known elastic contacts such as figure 1 As shown, it includes a head 1, a tail 3 and a mounting part 2 located between the head 1 and the tail 3. One end of the head 1 has two or more grooves 13, so that the head forms two Or more than two reeds 12, at the same time, the end of the reed 12 is inclined to the axis, so that the mouth size is smaller than the corresponding pin size, when the pin is inserted, the mouth of the reed 12 is forced to open, The contact between the mouth of the reed 12 and the pin generates pressure to achieve the purpose of forming an electrical connection between the pin and the elastic contact piece. Since the reed 12 will open when the pin is inserted, when th...
