Description
Technical field
The present invention relates to a kind of self-adaptive current bindiny mechanism of battery case, belong to mechanical structure field.
Background technology
Patent of invention 200710122367.0 discloses a kind of universal battery case; In the electrical connection of battery case, the electrode contact of interior case and outer container all is directly to be fixed on the electrode tip holder, after interior case and outer container are in place; Interior case relies on end face each other to contact conduction with the interior electrode contact of outer container; Interior outer container is movable relatively owing to the reason of vibrations in use, and the electrode contact contact plane of therefore interior outer container will inevitably produce parallelism error, thereby makes face electrodes in contact contact become line contact or some contact; Cause contact resistance to increase, simultaneously the appearance of guiding discharge phenomenon easily.
Summary of the invention
The present invention provides a kind of self-adaptive current bindiny mechanism of battery case, and interior case electrode contact can be followed the swing of outer container electrode contact under the effect of plain radial bearing, guarantees that electrode contact is in surface contact state all the time, has automatically reset function simultaneously.
A kind of self-adaptive current bindiny mechanism of battery case comprises cover behind electrode tip holder, the electrode, electrode bonnet, plain radial bearing, interior case electrode contact, spring coil, O type rubber ring, conduction flange and nut, and ancillary equipment is the outer container electrode tip holder; Wherein plain radial bearing is formed the sliding bearing of structure by one by the inner ring of spherical outside surface and outer ring by Internal Spherical Surface, can bear radial load, axial load or radially, axial simultaneous joint load; Interior case electrode contact is that cross section is a T font ledge structure; Be divided into big or small two ends; The big end end face of interior case electrode contact is a conductive contact surfaces, and small end is a guide end, on the big end cylindrical of interior case electrode contact circumferential ring-shaped groove is set one; Ring-shaped groove is fixed for O type rubber ring that electrode contact is resetted, and interior case electrode contact small end is used for attaching nut and flange; Its annexation is: plain radial bearing is through the installing hole interference fit of outer ring and electrode tip holder; Positioning step in one end of outer ring and the installing hole is conflicted; The other end of outer ring is installed on the electrode tip holder by spring coil, limits relatively moving of plain radial bearing and electrode tip holder; The O type rubber ring of packing in the ring-shaped groove of the big end of interior case electrode contact; O type rubber ring is connected with the corresponding inner hole wall extruding contact of electrode tip holder; The guide end of interior case electrode contact is packed into and is connected conduction flange and nut successively behind the inner ring of oscillating bearing; The conduction flange is used to be connected corresponding lead with nut, overlaps behind electrode tip holder and the electrode to be fixedly connected, and puts after at last the electrode bonnet being installed in electrode.
Wherein, interior case electrode contact outside diameter is less than the diameter of corresponding electrode tip holder endoporus, and the diameter of O type rubber ring cylindrical is greater than the diameter of the big end of interior case electrode contact.
Operation principle: after the outer container of battery case and interior case were in place, the outer container electrode contact in the outer container electrode tip holder contacted with each other with the end face of interior case electrode contact, the formation current path; Under the situation that vibrations occur, beat can take place in the outer container electrode contact, because the effect of plain radial bearing, interior case electrode contact can be followed outer container electrode contact beat simultaneously, thereby the surface that guarantees conduction remains surface contact state; When non operating state, because the effect of O type rubber ring, interior case electrode contact can automatically revert to horizontal initial position.
Beneficial effect:
1. interior case electrode contact can be swung with respect to electrode tip holder, realize between contact plane good fit with contact, overcome plane virtual connection or some contact that the straightness error because of the electrode contact post causes.
2. the inner ring of plain radial bearing is a hollow ball-shape; The cavity of outer ring is a sphere, and the combination of Internal and external cycle makes to have only the axial direction of guide post by the active force between electrode contact and the electrode tip holder; The torsional interaction that does not have the space guarantees the stressed even of electrode contact contact plane.
3.O the elasticity of type rubber ring utilization itself can reset in non operating state by interior case electrode contact.
4. interior case electrode contact is fixed in the degree of freedom of having only swing on the electrode tip holder, has prevented the axial endplay of electrode contact.
