Detailed description of the invention
Fig. 1 is the perspective view of hat spring and a banjo of the invention.
Fig. 2 is hat spring shown in FIG. 1 in the perspective view of another angle.
Fig. 3 is cross-sectional view of the hat spring shown in Fig. 2 along the direction A-A.
Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, right in the following with reference to the drawings and specific embodiments
The present invention is described in detail.
Please refer to the preferred embodiment that Fig. 1 ~ Fig. 3 show present invention hat spring 100.The hat spring 100 is surrounded by sheet metal,
The hat spring 100 includes along the axial end band 1 for being divided into hat 100 both ends of spring of the hat spring 100, is connected to two ends
Between band 1 and spaced several reeds 3.
Two end bands 1 and the reed 3 enclose the accommodating chamber 4 for setting and being formed for accommodating banjo 200 jointly, described
Accommodating chamber 4 is arranged in class waist-drum-shaped, i.e., gradually becomes along the internal diameter for being preced with the axial accommodating chamber 4 of spring 100 and intermediate on the whole
Small both ends are big.
Each end band 1 is the semiclosed circular ring structure that notch is axially arranged with along the hat spring 100, is convenient for the docking
Plug 200 is inserted into.Preferably, the notch of two end bands 1 forms an opening 5 along the axial connection of the hat spring 100.
The reed 3 extends between two end bands 1 along 100 axis direction of hat spring, and two neighboring described
There is gap 6, the width of the reed 3 is greater than the width in the gap 6 along the circumferencial direction of the hat spring 100 between reed 3
Degree.In the present embodiment, one of them described gap 6 is overlapped with the opening 5.
The reed 3 has the contact portion 31 of the axis direction projection towards the hat spring 100, the two neighboring reed
Contact portion 31 on 3 is located at the different location in hat 100 axial direction of spring；The described of the i.e. two neighboring reed 3 connects
Contact portion 31 is different along the axial distance to the same end band of the hat spring 100；To guarantee the hat spring 100 with dock
In the case that the contact points of plug 200 are constant, the hat spring 100 can have with banjo 200 to be contacted at many levels, is conducive to
Insertion force when banjo 200 is inserted into is reduced, operation is more convenient.
The axle center of all contact portions 31 and the hat spring 100 is equidistant so that the plug with it is all described
Contact portion 31 all has good in electrical contact, is effectively reduced the calorific value of contact interface, realizes larger current transmission, and can
Realize the reliable overlap joint between the hat spring 100 and banjo 200.
Axial along the hat spring 100, the contact portion 31 of the two neighboring reed 3 is respectively close to two institutes for being located at both ends
State end band 1.Further, the distance close to all contact portion 31 to the end bands 1 of the same end band 1 is identical,
I.e. all contact portions 31 form two contact rings with the banjo 200, significantly reduce the insertion of banjo 200
When insertion force, be more convenient operation.Further, all contact portions 31 to close to the contact portion 31 the end band
1 is equidistant.
Two reeds 3 positioned at each reed 3 along the two sides of hat 100 circumferencial direction of spring are uniformly arranged,
Two reeds 3 positioned at the two sides along hat 100 circumferencial direction of spring of the same reed 3 are identical therefore described
It is preced with spring 100 and the contact engaging and separating force of the banjo 200 is uniform, 200 stress of banjo is not susceptible to beat, can be improved described
The stability contacted between hat spring 100 and banjo 200.
Specifically, the reed 3 includes being directly connected to end band 1 described in one of them and axial straight along the hat spring 100
Straight segment 32 that line extends, the connection straight segment 32 and another described end band 1 and towards the axis direction of the hat spring 100
Projection bending section 33 in curved surface.The bending section 33 of the two neighboring reed 3 is directly connected in two positioned at both ends respectively
On the end band 1；The contact portion 31 is located in the bending section 33, and the contact portion 31 is relatively close to be equipped with the contact
The end band 1 that the bending section 33 in portion 31 is directly connected to.The preferably described contact portion 31 is located at the bending section 33 in the hat
Middle position in 100 axial direction of spring；The contact portion 31 of the two neighboring reed 3 is along the axially staggered setting of the hat spring 100.
In the present embodiment, axial along the hat spring 100, the length of the straight segment 32 is less than the length of the bending section 33
Degree；All straight segments 32 are identical along the axial length of the hat spring 100, and all bending sections 33 are along the hat spring 100
Axial length is identical；All contact portions 31 are to the end band 1 being directly connected to the bending section 33 for being equipped with the contact portion 31
It is equidistant.The structure of the two neighboring reed 3 is identical, only commutate alternately with the end band connection.
In conclusion hat spring 100 of the invention is by being located at the contact portion 31 on the two neighboring reed 3 along described
It is preced at the different location in 100 axial direction of spring, is guaranteeing the constant situation of the hat contact with banjo 200 of spring 100 points
Under, the hat spring 100 can have with banjo 200 to be contacted at many levels, advantageously reduces insertion when banjo 200 is inserted into
Power is more convenient operation.
The above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to preferred embodiment to this hair
It is bright to be described in detail, those skilled in the art should understand that, it can modify to technical solution of the present invention
Or equivalent replacement, without departing from the spirit and scope of the technical solution of the present invention.
