Embodiment Construction

[0010] A contact spring sheet of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0011] Such as Figure 1 ~ Figure 3 As shown, a contact spring sheet of the present invention includes a U-shaped connecting section 1 . One end of the first connecting arm 2 is connected to one end of the connecting section 1 , one end of the second connecting arm 3 is connected to the other end of the connecting section 1 , and one end of the extension arm 4 is connected to the other end of the second connecting arm 3 . The first connecting arm 2 and the second connecting arm 3 respectively extend in a direction away from the connecting section 1, and a circular arc transition design is adopted at the connection between the two and the connecting section 1 to reduce the stress concentration problem when the product is used, so as to increase the product quality. service life.

Abstract

The invention discloses a contact spring lamination. The contact spring lamination comprises a connecting section, a first connecting arm, a second connecting arm, an extended arm, and a neck, wherein the connecting section is in a structure with an opening in one end; one end of the first connecting arm is connected with one end of the connecting section; the connecting place between the first connecting arm and the connecting section is designed in an arc shape; one end of the second connecting arm is connected with the other end of the connecting section; the connecting place between the second connecting arm and the connecting section is designed in an arc shape; one end of the extended arm is connected with the other end of the second connecting arm; the neck is axially formed in the connecting section, the first connecting arm, the second connecting arm and the extended arm; a nick is formed in the tail end of the extended arm by the neck; the connecting section is U-shaped; and the contact spring lamination is made from chrome-nickel steel. According to the contact spring lamination, by designing the connecting places between the first connecting arm and the connecting section, and between the second connecting arm and the connecting section into the arc transitional shape, the stress concentration of the product in use is reduced, so that the service life of the product is prolonged; meanwhile, the nick is formed in the tail end of the extended arm by the neck, so that a dual-cage button wiring mode is realized; and therefore, the contact spring lamination is practical, convenient and reliable.

Description

technical field [0001] The invention relates to the electrical field, in particular to an electrical connection device, in particular to a contact spring. Background technique [0002] In the prior art, low-voltage electrical appliance branching modules are widely used in electrical circuit connections. In the low-voltage electrical branch line module, the elastic metal sheet is used to bend into a spring, which is used to clamp the terminal and facilitate the wiring operation. A current contact spring is prone to excessive stress during use, resulting in a short service life. Contents of the invention [0003] The purpose of the present invention is to provide a practical and reliable contact spring piece with prolonged service life. [0004] In order to solve the above technical problems, the present invention provides a contact spring piece, which includes a connection section, the connection section is an open-end structure; a first connection arm, one end of the...
