A kind of reed of Handle Bar

Technical field

The utility model relates to a kind of reed, relates in particular to a kind of reed that is used for the communication field Handle Bar.

Background technology

In communication product, generally include the perpendicular slotting or horizontal slotting circuit board plug-in (being Handle Bar) of polylith, other structures of the panel of these circuit board plug-ins and equipment constitute complete shield shell, and as shown in Figure 1, reed is mainly used to shielding electromagnetic wave.

Reed 20 shielding panels of Handle Bar 10 generally adopt the triangular form structure in the prior art, and as shown in Figure 2, it is generally stainless steel.In the installation process, because its narrow installation and low compression space under the effect of shearing force and normal pressure, very easily produce permanent deformation from the top circular arc.Shown in Fig. 3,4, very easily it is taken out of during the plug Handle Bar, thereby cause damaging.

Therefore, prior art awaits to improve and development.

The utility model content

The purpose of this utility model is to provide the reed that a kind of elastic restoring force is good, have the Handle Bar of resistance to deformation function, also has good screening effectiveness simultaneously and be easy to produce and assemble.

The technical solution of the utility model is as follows:

A kind of reed of Handle Bar, wherein, described reed middle part is set to the arc surface that a cross section is a circular arc, and the both sides of described reed bend inwards and form reed pin son, be used for described Handle Bar on the adaptive engaging of corresponding draw-in groove.

The reed of described Handle Bar, wherein, described reed is provided with at least one transverse opening groove, is used for described reed is divided into several load parts.

The reed of described Handle Bar, wherein, described transverse opening groove is set to a plurality of, and evenly distributes with constant spacing along the length direction of described reed.

The reed of described Handle Bar, wherein, described reed is the beryllium-bronze elastic material.

The reed of Handle Bar provided by the utility model, because its cross section is the both sides of circular arc setting and reed to bend inwards and forms and the adaptive reed pin son who engages of the draw-in groove of Handle Bar, strengthened the elastic restoring force of reed, thereby strengthened the deformation resistance of reed, guaranteed that reed contacts with the Handle Bar favorable conductive, the effect of shielding electromagnetic wave is better.

Embodiment

Below in conjunction with accompanying drawing each preferred embodiment of the present utility model is made a more detailed description.

The reed 40 of Handle Bar of the present utility model, as shown in Figure 5, this reed middle part is set to the arc surface 41 that a cross section is a circular arc, is used for shielding electromagnetic wave; And the both end sides of reed bends inwards and forms the first reed pin son 42, the second reed pin son 43, be used for Handle Bar on the adaptive engaging of corresponding draw-in groove, as shown in Figure 6.

On the arc surface 41 of the reed of the utility model Handle Bar, be provided with two transverse opening grooves 411, and evenly arranged evenly along the length direction of reed with constant spacing, arc surface 41 is divided into three load parts; So design makes arc surface 41 become three hard points by a hard point, has increased the load intensity of arc surface 41, has prolonged the useful life of the reed of Handle Bar.The reed of Handle Bar of the present utility model, the transverse opening groove 411 on its arc surface 41 can be set to one and also can be set to a plurality of.

The reed of the utility model Handle Bar, its middle part arc surface setting, so design can utilize circular arc top 410, makes reed 40 and Handle Bar 10 wait other circuit board panel to keep favorable conductive to contact, as shown in Figure 6.

In general the theory amount of being compressed of reed is 30%-85%, and the end that is compressed of the reed 40 of Handle Bar of the present utility model is designed to circular-arcly, has guaranteed that described reed 40 under ultimate deformation, does not produce permanent deformation.

The reed 40 of the utility model Handle Bar is when being subjected to the forward compression stress, also can be subjected to double direction shear power, its middle part arc surface setting has guaranteed no matter described reed 40 is in positive pressure, still under the lateral pressure state, remain the contact point of sustained height.

The reed 40 of the utility model Handle Bar, its both sides bend inwards and form the first reed pin son 42 and the second reed pin son 43, for inserting in the Handle Bar 10 corresponding draw-in grooves, reed provides correct importing angle, make it to be easy to insert, simultaneously, after having guaranteed its insertion Handle Bar 10 respective card slot, can because of being compressed, circular arc top 410 not being subjected to, being subjected to simultaneously side force from draw-in groove, to be taken out of down in working order.

The reed 40 of the utility model Handle Bar, the material that it adopted is the beryllium-bronze elastic material, compares the forward compression stress that has improved the elastic recovery of described reed 40 and reduced described reed with other material.

The reed 40 of the utility model Handle Bar and the installation process of Handle Bar 10, shown in Fig. 6,7,8, its step is as follows: at first the first reed pin young 42 with described reed 40 inserts in first draw-in groove 11 of Handle Bar 10; Gently press the circular arc top 410 of arc surface 41 then, utilize its strain; The second reed pin son 43 is slipped in second draw-in groove 12 of described Handle Bar along Handle Bar 10, then finished the installation of described reed 40 and Handle Bar 10.

In the actual production manufacturing process, Handle Bar 10 size dimensions shown in Fig. 6,7,8 have ± manufacturing tolerance of 0.15MM, in order to guarantee that reed 40 of the present utility model is not because of Handle Bar 10 change in size, and it is poor to produce bigger original height, generally the circular arc top 410 of arc surface 41 is manufactured with negative common difference.

Equally, in the actual production manufacturing process, Handle Bar 10 gauges shown in Fig. 6,7,8 have the tolerance of 0.2MM, in order to make reed of the present utility model 40 maximum magnitude ground engage adaptive with Handle Bar 10, and it is poor can not produce bigger original height, and bend inwards young 43 places of the first reed pin son 42, the second reed pin that form, the both sides of reed are designed to fitted position with the thickest Handle Bar coupling.

The reed of Handle Bar provided by the utility model because its cross section is the circular arc setting, has strengthened the elastic restoring force of reed, thereby has strengthened the deformation resistance of reed; Simultaneously since the both sides of reed bend inwards and form with the adaptive reed pin son who engages of Handle Bar draw-in groove and adopt the beryllium-bronze elastic material to make reed firm with the Handle Bar fastening, guaranteed that reed contacts with the Handle Bar favorable conductive, the effect of shielding electromagnetic wave is better.

Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion.And all these improvement and conversion all should belong to the protection range of the utility model claims.
