Embodiment
Describe the present invention below with reference to each execution mode shown in the drawings.But these execution modes do not limit the present invention, the structure that those of ordinary skill in the art makes according to these execution modes, method or conversion functionally are all included in protection scope of the present invention.
Please refer to Fig. 1 to the first better embodiment that Figure 2 shows that sheet spring contact 100 of the present invention.Described spring contact 100 is bent to form as C type or ring-type by square type tabular sheet metal, thus forms the containing cavity 10 in order to accommodate abutment element 200 in centre.The sheet spring matrix 1 that described spring contact 100 is arranged by C-shaped or ring-type and tear shaping some reeds 2 form on sheet spring matrix 1.
In the present embodiment, described spring matrix 1 is arranged in the form of a ring, and is provided with in the axial direction at two ends and arrange in the form of a ring two ends 11 and the jube 12 that is connected between two ends 11.Form some openings 121 between described jube 12, namely described reed 2 is tear formation from described opening 121 place.Adjacent described reed 2 is spaced from each other by described jube 12, is linked together two ends 11 simultaneously, ensures the intensity of sheet spring contact 100 of the present invention.
Described reed 2 extends along the axis direction of sheet spring matrix 1, and is connected along one end of sheet spring matrix 1 axis direction with described spring matrix 1, and the other end is that free state is arranged.Each reed 2 has the linking arm 21 be connected with described spring matrix 1 and the contact chip 22 extended from linking arm 21, and namely described contact chip 22 is arranged at the free end of reed 2, to facilitate the grafting of abutment element 200.Described contact chip 22 towards the projection of sheet spring matrix 1 axis direction, and is provided with the contact site 221 in order to abut against with abutment element 200.
In the present invention, reed 2 described in each has contact chip 22 described at least one pair of.At least one pair of contact chip 22 on each reed 2 is all connected with described linking arm 21, and arranges along the circumferencial direction interval of sheet spring matrix 1; Namely, contact site segmentation on each reed in prior art is set to contact chip 22 described at least one pair of by the present invention, arranged by this kind, sheet spring contact of the present invention 100 and the contact of abutment element 200 number at double of counting can be made to increase, thus effectively realize more big current transmission, contact area is reduced simultaneously, and then effectively reduces the caloric value of contact interface.
As depicted in figs. 1 and 2, in the present embodiment, some described reeds 2 being circumferentially arranged as a row and being uniformly distributed at described spring matrix 1, ensures abutment element 200 uniform force in a circumferential direction.Described contact site 221 is positioned at the centre position of sheet spring contact 100 on the axis direction of described spring matrix 1, docks comparatively stable to make the abutment element 200 inserted in containing cavity 10.
In addition, in present embodiment, on the axis direction of described spring matrix 1, the development length of described linking arm 21 is greater than the development length of described contact chip 22, thus, can be met the strain demand of described contact chip 22 on the one hand by described linking arm 21; On the other hand, make linking arm 21 arrange longer, and contact chip 22 can ensure the intensity of contact chip 22 relatively in short-term, and then the electric connection of guarantee and abutment element 200.Certainly, the length of described linking arm 21 can adjust accordingly setting according to the entire length of sheet spring matrix 1.
Refer to shown in Fig. 3 and Fig. 4, as another preferred embodiment of the present invention, some described reeds 2 ' are set on the axis direction of described spring matrix 1 ', be set at least two rows, be illustrated with two rows in the present embodiment, each arranges described reed 2 ' being circumferentially uniformly distributed at described spring matrix 1 '.That is, on the basis of the first preferred embodiment, making reed 2 ' realize multi-level contact, not easily there is beat when carrying out grafting in abutment element 200, can realize more reliably overlapping; In addition, contact is counted and is also become multiple to increase further, and then sheet spring contact 100 ' of the present invention can be made can to transmit more big current, and more effectively reduces the caloric value of each contact site.
In the present embodiment, the described reed 2 ' of two rows one_to_one corresponding on the axis direction of described spring matrix 1 ' is arranged, and the bearing of trend of described contact chip 22 ' is identical.
In addition, after arranging in two rows, the development length of described contact chip 22 ' on the axis direction of described spring matrix 1 ' is greater than the development length of described linking arm 21 ', to ensure the elastic contacting effect of described contact chip 22 '.
As known from the above, contact site on each reed 2,2 ' in prior art is carried out segmentation and is set to have at least one pair of contact chip 22,22 ' towards sheet spring matrix 1,1 ' axis direction projection by the present invention, and at least one pair of contact chip 22,22 ' is arranged along the circumferencial direction interval of sheet spring matrix 1,1 ', arranged by this kind, can make sheet spring contact of the present invention 100,100 ' and the contact of abutment element number at double of counting increase, thus effectively realize more big current transmission, contact area is reduced simultaneously, and then effectively reduces the caloric value of contact interface.
Be to be understood that, although this specification is described according to execution mode, but not each execution mode only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, technical scheme in each execution mode also through appropriately combined, can form other execution modes that it will be appreciated by those skilled in the art that.
A series of detailed description listed is above only illustrating for feasibility execution mode of the present invention; they are also not used to limit the scope of the invention, all do not depart from the skill of the present invention equivalent implementations done of spirit or change all should be included within protection scope of the present invention.
