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
The present invention relates to electric field, particularly relate to electrical connection, particularly a kind of contact spring sheet.
Background technology
In prior art, low-voltage electrical apparatus divides wire module to use extensively in electric wiring connects.Dividing in wire module at low-voltage electrical apparatus adopts elastic sheet metal to bend to spring, in order to block binding post, facilitates patching operations simultaneously.Current a kind of contact spring sheet easily produces the excessive situation of stress in the process used, and causes its useful life not long.
Summary of the invention
The object of the present invention is to provide one to increase the service life, practical reliable a kind of contact spring sheet.
For solving the problems of the technologies described above, a kind of contact spring sheet of the present invention, comprise linkage section, described linkage section is one end open formula structure; First linking arm, one end of described first linking arm is connected with one end of described linkage section, and the junction of described first linking arm and described linkage section is designed arc-shaped appearance; Second linking arm, one end of described second linking arm is connected with the other end of described linkage section, and the junction of described second linking arm and described linkage section is designed arc-shaped appearance; Extension arm, one end of described extension arm is connected with the other end of described second linking arm; Draw-in groove, described draw-in groove is axially disposed within described linkage section, described first linking arm, described second linking arm and described extension arm, and described draw-in groove forms breach at the end of described extension arm.
Described linkage section is U-shaped.The material of described a kind of contact spring sheet is chrome-nickel steel.
A kind of contact spring sheet of the present invention adopts arc transition design in the junction of the first linking arm and the second linking arm and linkage section, reduces problem of stress concentration when product uses, increases the useful life of product; Meanwhile, draw-in groove forms breach at the end of extension arm, realizes two cage button wiring, and reliably practical and convenient; And adopting high strength chromium nickel spring steel spring, spring wiring quality is more firm.
Accompanying drawing explanation
Fig. 1 is a kind of contact spring sheet of the present invention front view;
Fig. 2 is a kind of contact spring chip architecture of the present invention schematic diagram one;
Fig. 3 is a kind of contact spring chip architecture of the present invention schematic diagram two.
Embodiment
Below in conjunction with accompanying drawing, a kind of contact spring sheet of the present invention is described in further detail.
As shown in FIG. 1 to 3, a kind of contact spring sheet of the present invention, comprises the linkage section 1 of U-shaped.One end of first linking arm 2 is connected with one end of linkage section 1, and one end of the second linking arm 3 is connected with the other end of linkage section 1, and one end of extension arm 4 is connected with the other end of the second linking arm 3.First linking arm 2 and the second linking arm 3 extend towards the direction away from linkage section 1 respectively, and adopt arc transition design in the junction of both and linkage section 1, reduce problem of stress concentration when product uses, to increase the useful life of product.
Draw-in groove 5 is axially disposed within linkage section 1, first linking arm 2, second linking arm 3 and extension arm 4, and draw-in groove 5 forms breach 6 at the end of extension arm 4, realizes two cage button wiring, and reliably practical and convenient.
And a kind of contact spring sheet of the present invention adopts high strength chromium nickel spring steel spring, makes spring wiring quality more firm.
A kind of contact spring sheet of the present invention adopts arc transition design in the junction of the first linking arm and the second linking arm and linkage section, reduces problem of stress concentration when product uses, increases the useful life of product; Meanwhile, draw-in groove forms breach at the end of extension arm, realizes two cage button wiring, and reliably practical and convenient; And adopting high strength chromium nickel spring steel spring, spring wiring quality is more firm.
Below the preferred embodiment of the invention is illustrated, but the present invention is not limited to embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite without prejudice to the invention spirit, and these equivalent modification or replacement are all included in the scope of the application.
