Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Refer to the preferred embodiment of Fig. 1 ~ Figure 3 shows that the utility model hat spring 100.Described hat spring 100 is surrounded by the sheet metal of rectangle, described hat spring 100 comprise along described hat spring 100 be axially divided into described hat spring 100 two ends end band 1, between two end band 1 in band 2, be connected to some reeds 3 between two described end band 1 and described middle band 2.
Two described end band 1, described middle band 2 and described reeds 3 enclose the host cavity 4 formed for accommodating banjo 200 jointly; And end band 1, middle band 2 described in each and to connect this end band 1 with the combination of the described reed 3 of described middle band 2 be that waist-drum-shaped is arranged, namely described host cavity 4 is waist-drum-shaped setting; Along described hat spring 100, axially described host cavity 4 is broad in the middle and first reduce gradually to become large more gradually from the middle to both ends.Thus when banjo 200 inserts described hat spring 100, can carry out in electrical contact with the described reed 3 being divided into described middle band 2 both sides, contact point increases, and carries out big current transmission with effectively reducing each contact-making surface caloric value and then Absorbable organic halogens; Described hat spring 100 is even with the contact engaging and separating force of banjo 200 simultaneously, and banjo 200 is stressed not easily beat occurs, and can improve the stability of the Contact of described hat spring 100 and banjo 200.
Described end band 1 is the semiclosed circular ring structure being provided with the first breach vertically, is convenient to described banjo 200 and inserts.Described end band 1 has the end 11 being positioned at described hat spring 100 two ends and the first connecting portion 12 connecting described end 11 and some described reeds 3, and one end of the interior end without leave 11 of described first connecting portion 12 reduces formation curved surface gradually towards the one end connecting reed 3.
Be similar to described end band 1, on described middle band 2, the position corresponding with described first breach is provided with the second breach, and two described first breach are axially communicated with formation opening 5 with the second breach along described hat spring 100.Described middle band 2 has and is arranged in middle its central band 21 and is divided into described its central band 21 both sides and connects the second connecting portion 22 of described its central band 21 and described reed 3, and during the internal diameter of described second connecting portion 22 connects, one end of its central band 21 reduces formation curved surface gradually towards the one end connecting reed 3.
Reed 3 described in each axially extends along described hat spring 100 between described end band 1 and described middle band 2, and described reed 3 is positioned on same curved surface with the first connecting portion 12 and the second connecting portion 22 being positioned at described reed 3 two ends.Some described reeds 3 are circumferentially evenly arranged at described hat spring 100, and have gap 6 between adjacent two described reeds 3, and the width along the circumferentially described reed 3 of described hat spring 100 is greater than the width in described gap 6.In the present embodiment, one of them gap 6 overlaps with described opening 5.
Each reed 3 has the contact site 31 towards the axis direction projection of described hat spring 100, all described contact sites 31 are equal with the distance in the axle center of described hat spring 100, and the internal diameter of the contact ring that the described contact site 31 being namely arranged in described band 2 side is formed is identical with the internal diameter of the contact ring that the described contact site 31 being arranged in described band 2 opposite side is formed; Described plug and all described contact sites 31 are all had good in electrical contact, effectively reduce the caloric value of contact interface, realize larger current transmission, and the reliable overlap joint between described hat spring 100 and banjo 200 can be realized.In the present embodiment, described contact site 31 is positioned at the centre position of described reed 3 on described hat spring 100 axis direction.
Further, described contact site 31 is provided with convex closure 311 towards the side of the axis direction of described hat spring 100, the inner side of described convex closure 311 is equal with the distance in the axle center of described hat spring 100, and described convex closure 311 can be set to the various shapes such as circle, semicircle, strip, to realize the reliable overlap joint of described hat spring 100 and described plug.
The described reed 3 being divided into described middle band 2 both sides is symmetrical set; The described gap 6 being divided into described middle band 2 both sides is symmetrical set.Also namely along described hat spring 100 axially, be arranged in described band 2 side each described in reed 3 extended along same straight line with the described reed 3 being arranged in described band 2 opposite side; Be arranged in described band 2 side each described in gap 6 extended along same straight line with the described gap 6 being arranged in described band 2 opposite side.
In another embodiment (not shown), be divided into the described reed 3 of described middle band 2 both sides in being crisscross arranged; Also be namely arranged in described band 2 side each described in reed 3 extended along same straight line with the gap 6 being arranged in described band 2 opposite side.
In sum, hat spring 100 of the present utility model is by being equipped with reed 3 in middle band 2 both sides, and each reed 3 has towards the contact site 31 of the axis direction projection of described hat spring 100, make described hat spring 100 can have multi-level contact with banjo 200, contact counts to count at double to be increased, and carries out big current transmission with effectively reducing each contact-making surface caloric value and then Absorbable organic halogens; Described hat spring 100 is even with the contact engaging and separating force of banjo 200 simultaneously, and banjo 200 is stressed not easily beat occurs, and can improve the stability of the Contact of described hat spring 100 and banjo 200.
Above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not depart from the spirit and scope of technical solutions of the utility model.
