Although above-mentioned bulging spring structure can play the effect of electrical connection, but when using the bulging spring of this structure, the contact resistance value between contact pin and drum spring is higher, is generally capable of up to 0.35 milliohm, the higher consumption that can increase the energy of contact resistance value, and then make cost increase.
Utility model content
Utility model purpose:For problems of the prior art, this utility model provides one drum spring and electrical connection module, and this drum spring and sleeve and contact pin are with the use of rear, and contact pin and the resistance value roused between spring can reduce about 0.05 milliohm, effectively reduce resistance and reduce loss, improve the utilization rate of the energy.
Technical scheme:This utility model provides a kind of drum spring, the semi-enclosed column structure of this drum spring generally axially open, the middle part circumference of described bulging spring is evenly distributed with some contact flat springs, each contact flat spring is respectively provided with at least two the most axially distributed, to drum spring internal protrusion crest.
Preferably, described contact flat spring is respectively provided with two described crests.
Preferably, described bulging spring forms described semi-enclosed column structure entirely through running through its axial expansion joint.
Preferably, the surfaces externally and internally of described bulging spring is all coated with protective layer；Described protective layer is tin layers.
This utility model additionally provides a kind of electrical connection module, on including bulging spring, also include sleeve and contact pin, described bulging spring is arranged between described sleeve and described contact pin, the lateral wall of described bulging spring effectively contacts with the medial wall, one end of described sleeve, and the lateral wall, one end of described contact pin effectively contacts with the crest on each described contact flat spring in described bulging spring.
Beneficial effect:nullIn bulging spring structure in this utility model，The crest to drum spring internal protrusion that at least two is sequentially distributed vertically it is respectively provided with on each contact flat spring，After rousing spring and sleeve and contact pin assembling，Drum spring effectively contacts between at least two crest and the outer surface of contact pin on contact flat spring，Compared with equivalently-sized the contact flat spring with a crest，During multiple crest, at least one of which crest and the contact point of contact pin are less to the spacing of contact pin afterbody，Be equivalent to shorten the contact length between contact pin and drum spring，All have point of contact between the most multiple crests and contact pin，Also correspond to the contact area adding contact pin with drum spring，Contact resistance value between contact pin and drum spring can be reduced to below about 0.30 milliohm by the effect in terms of above-mentioned two，With on contact flat spring during only one of which crest compared with contact resistance value about 0.35 milliohm，Reduce about 0.05 milliohm，Thus decrease resistance、Reduce loss and improve energy utilization rate.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in detail.
Embodiment 1:
Present embodiments provide for a kind of drum spring 1, as shown in Fig. 3 ~ 5, this drum spring 1 forms the semi-enclosed column structure of axially open entirely through running through its axial expansion joint 102, and it is internal that the design at expansion joint 102 makes drum spring 1 can be installed to sleeve 2 easily；Middle part circumference at drum spring 1 is evenly distributed with multiple contact flat spring 101, hole is equidistantly left between each contact flat spring 101, and be respectively provided with on each contact flat spring 101 two the most axially distributed, to the crest of drum spring 1 internal protrusion, noticing that the position of first crest on each contact flat spring 101 is respectively positioned on to be perpendicular in the same plane that drum spring 1 is axial, the position of second crest is also respectively positioned on and is perpendicular in the same plane that drum spring 1 is axial；Bulging spring 1 in present embodiment is made up of C17200 material, and its surfaces externally and internally is all coated with tin layers as protective layer.
Embodiment
2
:
Present embodiments provide for a kind of electrical connection module, as shown in Figure 6, this electrical connection module is made up of the bulging spring 1 in embodiment 1 and sleeve 2 and contact pin 3, drum spring 1 is arranged in the medial wall of sleeve 2 one end, then one end of contact pin 2 is inserted inside drum spring 1 and i.e. constitute the electrical connection module in present embodiment, after installing, drum spring 1 is between sleeve 2 and contact pin 3, the lateral wall of drum spring 1 effectively contacts with the medial wall of sleeve 2 one end, rouses the lateral wall all with contact pin 3 of each crest on each contact flat spring 101 of spring 1 and effectively contacts.
nullAs can be seen from Figure 6，Contact pin 3 right-hand member to drum spring 1 first crest of right-hand member distance c about 26.82mm，Contact pin 3 right-hand member is about 57.5mm to total distance b of sleeve 2 left end，In comparison diagram 2 prior art, the crest of drum spring 100 is 28.23mm to distance a of contact pin 3 right-hand member，Contact pin 3 right-hand member is also about 57.5mm to total distance b of sleeve 2 left end，Visible，In present embodiment，Contact pin 3 right-hand member is to first crest distance c distance a less than contact pin 3 right-hand member in prior art to drum spring 100 crest rousing spring 1，Thus reduce contact pin 3 right-hand member spacing to drum spring 1 crest，And present embodiment has two crests being sequentially distributed on the contact flat spring 101 of drum spring 1，Two crests all contact with contact pin 3 lateral wall，Compared with the contact flat spring of only one of which crest in drum spring 100 in prior art，The contact flat spring 101 of two crests is bigger with the contact area of contact pin 3，On the one hand spacing reduces，On the other hand contact area increases，Both sides effect makes the contact resistance between contact pin 3 and drum spring 1 reduce about 0.05 milliohm，The reduction of contact resistance can effectively reduce loss，Thus promote the utilization rate of the energy.
