Description

A kind of contact elastic slice

Technical field

The utility model relates to electronic component more particularly to a kind of contact elastic slices.

Background technique

Contact elastic slice belongs to electrical contact element, it mainly connects, carries and the effect of breaking current, traditional contact bullet Piece (such as Fig. 1), including cantilever and contact portion, power act on cantilever, and cantilever is made to generate deformation, realize connection and breaking operation, Due to the limited yield limit with material, when reaching biggish deflection, need using longer cantilever, the i.e. Vertical Square of power It is larger to required space, be not suitable for the use of miniaturized element.

Utility model content

The applicant is directed to disadvantage mentioned above, has carried out Improvement, provides a kind of contact elastic slice.

Technical solution used by the utility model is as follows:

A kind of contact elastic slice, including attachment base, the attachment base connect contact portion by elastic arm, and attachment base connects for fixed Contact point elastic slice, attachment base, elastic arm and contact portion are integrally formed by conductive metal sheet one bending, and elastic arm is at least through primary Bending forms bending part.

As a further improvement of the above technical scheme:

The conductive metal sheet is copper sheet.

Location hole is opened up on attachment base.

The beneficial effects of the utility model are as follows: the contact elastic slice, several bending parts formed by bending on elastic arm, Deformation can be superimposed in the direction of the force, greatly improve the deflection of elastic slice, can save with the space in power vertical direction, be suitble to Miniaturized element is installed and used.

Detailed description of the invention

Fig. 1 is the front view of traditional contact elastic slice.

Fig. 2 is the front view of the contact elastic slice of the present embodiment.

Fig. 3 is the top view of the contact elastic slice of the present embodiment.

In figure: 1, attachment base；11, location hole；2, elastic arm；21, bending part；3, contact portion.

Specific embodiment

With reference to the accompanying drawing, illustrate the specific embodiment of the present embodiment.

As shown in Figure 2 and Figure 3, the contact elastic slice of the present embodiment, including attachment base 1, attachment base 1 pass through the connection contact of elastic arm 2 Portion 3, attachment base 1 are formed for being fixedly connected with contact elastic slice, attachment base 1, elastic arm 2 and 3 one of contact portion by copper sheet one bending, And elastic arm 2 forms three bending parts 21 by bending three times, and location hole 11 is opened up on attachment base 1, guarantees that attachment base 1 positions standard Really, the width of attachment base 1 is greater than the width of elastic arm 2 and contact portion 3, and guarantee has biggish installation space.

When the contact elastic slice produces, first passes through die cutting device punching copper sheet and be punched into contact elastic slice plate, and connecting It is punched into location hole 11 on the position of seat 1, the bending operation of contact elastic slice plate is then carried out by bending equipment, bending is formed Bending part 21 and contact portion 3 complete the production of contact elastic slice, after the completion of production, can carry out contact elastic slice assembly, first pass through The cooperation of location hole 11 positions contact elastic slice on attachment base 1, and the seat 1 that is cooperatively connected fixes contact elastic slice, can be completed Entire contact elastic slice assembly work.

Above description is the explanation to the utility model, is not the restriction to utility model, defined by the utility model Range is referring to claim, and without prejudice to the basic structure of the utility model, the utility model can make any shape The modification of formula.
