Abstract
The utility model relates to an electrical connecting structure of a battery. The electrical connecting structure of the battery comprises an end cover with an electrode cap, wherein a conductive plate is electrically connected with the bottom end of the electrode cap at the inner side of the end cover and is at least provided with a transverse electrical connecting surface; convex posts are arranged on the position at the inner side of the end cover, corresponding to the transverse electrical connecting device of the conductive plate; and the tail ends of the convex posts prop against the transverse electrical connecting surface of the conductive plate. Compared with the prior art, the electrical connecting structure of the battery has the advantages as follows: the tail ends of the convex posts can prop against the transverse electrical connecting surface of the conductive plate all the time by utilizing the micro-deformation capacity of the convex posts through a design that the conductive plate is matched with the convex posts at the inner side of the end cover, so that the transverse connecting surface of the conductive plate is always kept to electrically contact with positive and negative electrode ends of a battery cell, and therefore, a conventional spot-welding connecting way is abandoned. Besides, the electrical connecting structure of the battery can easily realize the automatic assembling, is simple in structure and convenient to install.
Description
Technical field
The utility model relates to a kind of battery, relates in particular to a kind of electric connection structure of battery.
Background technology
Voltaic battery in the market is made up of housing, end cap and the mutual series connected battery core of 6 joints that is assemblied in the inside, the formation positive and negative electrode end after 6 batteries cores are connected mutually respectively with end cap on corresponding electrode cap be electrically connected.In the prior art, being connected by conducting strip spot welding and the continuous of positive and negative electrode end of battery and electrode cap, practical operation is more time-consuming, and spot welding is manual operations, realizes that the difficulty of automation assembling is big.Simultaneously, battery in use, often because fortuitous event such as drop, solder joint is impaired, causes the electrode tip of battery and the electrode cap can't excellent electric contact, makes product normally not use then, need to change entire cell, useful life deficiency, and use cost increases.
The utility model content
Technical problem to be solved in the utility model is the electric connection structure that the battery that a kind of non-spot welding mode is electrically connected is provided at above-mentioned prior art present situation, it can guarantee the positive and negative electrode end of battery and the excellent electric contact of electrode cap constantly, simple in structure, easy for installation, realize the automation assembling easily.
The utility model solves the problems of the technologies described above the technical scheme that adopts: the electric connection structure of this battery, comprise the end cap that has electrode cap, it is characterized in that: described end cap inboard, be electrically connected with a conducting strip with the bottom of electrode cap, this conducting strip has a transverse electric joint face at least, and, the transverse electric joint face position of the inboard corresponding conducting strip of described end cap is provided with projection, and the transverse electric joint face of the end of this projection and described conducting strip offsets.
For strengthening described projection in the vertical direction amount of elastic deformation, as improvement, the end of described projection has slick and sly surface, and this projection has the groove that radially distributes, to form a plurality of discrete duckpins.When reality is practical, when projection is tight against conducting strip and is squeezed, a plurality of duckpins can relatively outwards separate or inwardly close up, and to guarantee projection to the effect that suitably is tight against of conducting strip, guarantee that the transverse electric joint face of conducting strip well contacts with the positive and negative electrode end of battery.
Described conducting strip can adopt different shape, and preferably, it is Z-shaped that described conducting strip can be, and its top links to each other with the bottom of electrode cap, and its bottom is exactly described transverse electric joint face.In addition, the bottom of this Z-shaped conducting strip can also be downward-sloping slightly, to guarantee contacting of transverse electric joint face and battery electrode tip.
Preferably, described conducting strip can be L-shaped, and its top links to each other with the bottom of electrode cap, and its lateral part is described transverse electric joint face.
Compared with prior art, advantage of the present utility model is: cooperate the design of the inboard projection of end cap by conducting strip, little deformability of utilizing projection itself to have, the end of projection can be tight against the transverse electric joint face of conducting strip all the time, make the transverse electric joint face of conducting strip remain and the electrically contacting of the positive and negative electrode end of battery, abandoned traditional spot welding connected mode, realize the automation assembling easily, be beneficial to the batch process of product, increase the useful life of battery, improved the comfort of product, and simple in structure, easy for installation, wherein projection can adopt plastics, with the end cap integrated injection molding.

Embodiment
Describe in further detail below in conjunction with the utility model of accompanying drawing embodiment.
Shown in Fig. 1～4, this application has the battery of the electric connection structure of the utility model embodiment, comprise housing 1, be arranged on the battery 2 in the housing 1 and have the end cap 4 of electrode cap 3, this battery 2 has the positive and negative electrode end and is electrically connected with corresponding electrode cap 3 respectively.
Wherein, electric connection structure is in the inboard of end cap 4, is electrically connected with one with the bottom of electrode cap 3 and is Z-shaped conducting strip 6, its top links to each other with the bottom of electrode cap 3, its bottom is transverse electric joint face 61, in addition, be provided with projection 7 in transverse electric joint face 61 positions of end cap 4 inboard corresponding conducting strips 6, the end that this projection 7 has a slick and sly surface just in time offsets with the transverse electric joint face 61 of conducting strip 6, projection 7 also has the groove 72 that radially distributes, to form a plurality of discrete duckpins 71.
After assembling was finished, each projection 7 was tight against the transverse electric joint face 61 of each conducting strip 6, make transverse electric joint face 61 be close to battery 2 just/negative electricity is extreme, finally guarantee electrode cap 3 and battery 2 just/extreme being electrically connected of negative electricity.
