Description

Elastic sheet connector

Technical field

This application involves electric connector field, espespecially a kind of elastic sheet connector.

Background technique

No. 201621220390.4 patent application of the People's Republic of China (PRC) discloses a kind of elastic sheet connector, the elastic slice Connector includes substrate, the first level arm extended to form from substrate longitudinal direction one end inverse bending, from the first level The second horizontal arm and tilt upward the contact portion extended to form from second horizontal arm that arm end inverse bending extends to form. When the contact portion is pressed down, the arm of force is from contact portion to substrate with the junction of first level arm, and the arm of force is longer at this time, under When pressure height is identical, the vertical misalignment amount of contact portion is larger, and space utilization is limited.

Utility model content

In consideration of it, it is necessary to provide a kind of lesser elastic sheet connectors of contact portion offset.

In order to solve the above technical problems, provide a kind of elastic sheet connector, including it is substrate, more from substrate longitudinal direction one end Elastic arm that secondary bending extends to form is formed in the contact portion on the elastic arm top and vertically rolls over from the substrate both lateral sides The curved flap for extending the elastic arm two sides, the elastic arm include the formed from substrate longitudinal direction one end inverse bending One horizontal arm offers window on the flap, and the window lower part, which has extended inwardly to form, is connected to the first level arm The support chip of lower section.

Preferably, the elastic arm further includes from institute's substrate the first vertical arm that vertical bending is formed upwards, from described the The first level arm that the vertical bending in one vertical arm top extends to form, from the first level arm, vertical bending extends upwards The second vertical arm for being formed and the oblique arm to be formed is extended obliquely upward from the top of second vertical arm.

Preferably, the contact site is in the top of the oblique arm.

Preferably, the elastic sheet connector further includes the pre- pressure arm being downwardly extending from the contact portion inverse bending, The end bending of the pre- pressure arm is horizontal, and the both lateral sides of the end extend to form width greater than the pre- pressure arm width Pre- splenium.

Preferably, the pre- splenium of the pre- pressure arm extends into the window, and limits precompressed by the upside of the window.

Preferably, the elastic arm further includes tilting down the depression that bending extends to form from second vertical arm, The oblique arm is to extend obliquely upward to be formed from the depression end.

Preferably, the contact portion extends upward at the top of the flap, and the flap is in the correspondence depression position Locate vertical bending and extends to form emulsion sheet above the depression.

The application compared to the prior art, is extended to form below the first level arm by the bottom in window Support chip when contact portion pushes, is limited to deformation above the support chip, reduces the arm of force, make the longitudinal direction of the contact portion Offset reduces.

Specific embodiment

To keep the purposes, technical schemes and advantages of the application clearer, below in conjunction with the application specific embodiment and Technical scheme is clearly and completely described in corresponding attached drawing.Obviously, described embodiment is only the application one Section Example, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not doing Every other embodiment obtained under the premise of creative work out, shall fall in the protection scope of this application.

Referring to FIG. 1 to 2, the application elastic sheet connector include substrate 10, it is multiple from the longitudinal one end of the substrate 10 Elastic arm 20 that bending extends to form, the contact portion 40 for being formed in 20 top of elastic arm and from 10 both lateral sides of substrate Vertical bending extends the flap 30 of 20 two sides of elastic arm.

The elastic arm 20 include the first vertical arm 21 extended to form from the vertical bending in the longitudinal one end of the substrate 10, from First vertical arm, 21 top first level arm 22 that vertically bending extends to form hangs down from 22 free end of first level arm The second vertical arm 23 that bending is formed straight upwards is sunk from what the 23 top downward bending of the second vertical arm extended to form Portion 24 and the oblique arm 25 to be formed is extended obliquely upward from 24 end of depression.The contact portion 40 is located at the top of the oblique arm 25 End.

The elastic sheet connector further includes the pre- pressure arm 50 being downwardly extending from 40 inverse bending of contact portion, described 51 bending of end of pre- pressure arm 50 is horizontal, and the both lateral sides of the end 51 extend to form width greater than the pre- pressure arm 50 The pre- splenium 52 of width.

The flap 30 is located at the both lateral sides of the elastic arm 20, offers window 31, the window on the flap 30 The bottom of mouth 31 is inwardly stamped and formed out the support chip 32 for being connected to 22 bottom of first level arm.The precompressed of the pre- pressure arm 50 Portion 52 extends into the window 31, and limits precompressed by the upside of the window 31.The contact portion 40 extends upward institute 30 top of flap is stated, the vertical bending at correspondence 24 position of depression of at least one of described flap 30 extends to form position Emulsion sheet 33 above the depression 24.

With continued reference to shown in Fig. 3, when contact portion 40 is pressed down in running order, when initial, the elastic arm 20 The distance between the junction of first level arm 22 and the first vertical arm 21 and the contact portion 40 are torque arm length；And described When one deformation downwards of horizontal arm 22, the first level arm 22 is supported by the support chip 32, and the length of the arm of force is still limited at this time System is between the contact portion 40 and the first level arm 22；In this way, reducing the arm of force, make the vertical misalignment of the contact portion 40 Amount reduces.The design of the depression 24 can increase the elastic force of the oblique arm 25.

The application compared to the prior art, by being extended to form under the first level arm 22 in the bottom of window 31 The support chip 32 of side when contact portion 40 pushes, makes deformation be limited to 32 top of support chip, reduces the arm of force, make described connect The vertical misalignment amount of contact portion 40 reduces.

It should also be noted that, the terms "include", "comprise" or its any other variant are intended to nonexcludability It include so that the process, method, commodity or the equipment that include a series of elements not only include those elements, but also to wrap Include other elements that are not explicitly listed, or further include for this process, method, commodity or equipment intrinsic want Element.In the absence of more restrictions, the element limited by sentence "including a ...", it is not excluded that including described want There is also other identical elements in the process, method of element, commodity or equipment.

The above description is only an example of the present application, is not intended to limit this application.For those skilled in the art For, various changes and changes are possible in this application.All any modifications made within the spirit and principles of the present application are equal Replacement, improvement etc., should be included within the scope of the claims of this application.
