Abstract
The utility model discloses contact spring piece, including the linkage segment, the linkage segment is one end open type structure, first linking arm, the one end of first linking arm is connected with the one end of linkage segment, and first linking arm designs for the circular arc with the junction of linkage segment, the second linking arm, the one end of second linking arm is connected with the other end of linkage segment, and the second linking arm designs for the circular arc with the junction of linkage segment, extension arm, extension arm's the one end and the other end of second linking arm are connected, the draw -in groove, the draw -in groove axial sets up in linkage segment, first linking arm, second linking arm and extension arm, and terminal the form breach of draw -in groove at extension arm. The linkage segment is the U -shaped. Contact spring piece's material is chrome -nickel steel. The utility model discloses adopt circular arc transition design in first linking arm and second linking arm and the junction of linkage segment, stress concentration problem when reducing the product and using increases the life of product, simultaneously, the wiring of two cage button is realized at extension arm's the terminal breach that forms to the draw -in groove, and practical convenient and reliable.
Description
Technical field
The utility model relates to electric field, particularly relates 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 contact spring sheet easily produces the excessive situation of stress in the process used, and causes its useful life not long.
Utility model content
The purpose of this utility model is to provide one to increase the service life, practical contact spring sheet reliably.
For solving the problems of the technologies described above, the utility model contact spring sheet, comprises linkage section, and 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 contact spring sheet is chrome-nickel steel.
The utility model contact spring sheet 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 the utility model contact spring sheet front view;
Fig. 2 is the utility model contact spring chip architecture schematic diagram one;
Fig. 3 is the utility model contact spring chip architecture schematic diagram two.
Embodiment
Below in conjunction with accompanying drawing, the utility model contact spring sheet is described in further detail.
As shown in FIG. 1 to 3, the utility model contact spring sheet, 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 the utility model contact spring sheet adopts high strength chromium nickel spring steel spring, makes spring wiring quality more firm.
The utility model contact spring sheet 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 that the utility model is created is illustrated, but the utility model 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 utility model creative spirit, and these equivalent modification or replacement are all included in the scope of the application.
Claims (3)
