Abstract
The invention discloses a connecting method of power type batteries with internal screw-threaded polar posts. According to the connecting method disclosed by the method, polar posts are connected with connecting sheets closely by using particular screw rods with screw threads in opposite helical directions at both ends, so that serial connection and parallel connection effects are realized; and at last, a screw thread contact place of the connecting sheet and the screw rod is glued to prevent looseness. The method is most noticeably characterized in that conventional planar contact between the polar posts and the connecting sheets is changed, and a threaded surface contact which is more reliable in connection and larger in contact area is employed, thus an effective contact area is increased greatly while possible potential safety hazard caused by unevenness of the plane is eliminated.
Description
Technical field
The present invention relates to a kind of batteries packing technique, be specifically related to a kind of for the method for attachment of power type accumulator battery I.S.S pole.
Background technology
Motive-power battery with I.S.S pole commonly used connected mode when carrying out the connection in series-parallel connection is that brace is directly fastening with bolt.This kind mode is simple to operate, only needs to use simple tools (spanner) can finish whole connection procedure.The pole connection that has the motive-power battery of I.S.S pole at present mainly is exactly to adopt this mode.But there are the following problems in application for this mode:
1. the contact area between brace and the pole is little, thereby makes that the contact internal resistance is bigger.In this kind connected mode, the contact area of brace and pole depends on the minimum area that bolt and brace and brace and pole bottom platform partly contact.And effective contact area of bolt is less usually, therefore causes whole effective contact area less, makes that the connection internal resistance is bigger.
2. work as bolt, brace, three zones of pole terrace part as long as there are slight out-of-flatness or dislocation in any one zone, then it just effectively contacts and might become the contact of part face or even some contact from whole face contact, it is a lot of greatly that the contact internal resistance of this moment more normally contacts internal resistance, to cause tie point overheated when serious, thus the potential safety hazard of causing.
Therefore, adopting brace at present more than is not the desirable connected mode of I.S.S pole battery with the mode of bolted directly.
Summary of the invention
Thereby the object of the invention is to provide a kind of not only can have been increased contact area and reduced to connect internal resistance but also contactless bad potential safety hazard, and what also have simple and quick advantage simultaneously is used for the method for attachment of motive-power battery I.S.S pole.
The technical solution used in the present invention is: a kind of be used to having the method for attachment of I.S.S pole motive-power battery, may further comprise the steps:
1) make two ends and have opposite threads and reach unanimity, and the middle connecting screw rod that the polygon boss that conveniently turns is arranged;
2) make the connecting elements of the connector in the band left-hand thread hole that is complementary with connecting screw rod one end;
3) spring shim is aimed at the screwed hole of first battery electrode column, another spring shim is placed in screw thread one end that connecting screw rod has antispin direction;
4) two ends of connecting screw rod are aimed at the screwed hole of the first battery electrode column hole and connector respectively by the screw thread matching direction;
5) tool using turns connecting screw rod until tightening;
6) carry out the anti-loosening processing of a glue in the screw thread contact position of connector and connecting screw rod;
7) identical with above-mentioned first battery electrode column for the connection of second battery electrode column, realize that finally I.S.S pole motive-power battery connects.
As preferably, above-mentioned steps 2) connecting elements is brace or connecting line in.
Pole method of attachment among the present invention is applicable to the connection with I.S.S structure pole battery.
The present invention at first correctly places spring shim, then the double-screw bolt two ends are aimed at the screwed hole of the first battery electrode column hole and connector respectively, rotary screw makes and closely contacts between the connector of screw rod and battery electrode column and screw rod and brace or connecting line, it reached prevent the purpose become flexible by carry out the locking processing of a glue in connector and screw flight contact position more at last.The present invention not only technology is simple, easy to operate, and need not complex apparatus in this way, and can greatly reduce connection internal resistance and the hidden danger of eliminating loose contact between battery pack, be a kind of very desirable assembling mode for the battery with I.S.S pole.
The method that the special screw rod that the present invention adopts two ends to have opposite helical direction screw thread connects closely couples together pole and brace, thereby reach series-parallel effect, carry out anti-loosening processing at brace and the gluing of screw flight contact position point at last, its maximum is characterised in that and has changed plane contact traditional between pole and the connector, but adopt contact area bigger, connect the contact of more reliable flank, this way has also been eliminated the out-of-flatness on plane and issuable potential safety hazard when having increased effective contact area greatly.
Beneficial effect:
1. technology of the present invention has greatly reduced the evenness of the contact-making surface of brace and battery electrode column and the requirement of smoothness in battery electrode column and the traditional method of attachment;
2. technology of the present invention has been eliminated the connection potential safety hazard that the brace connection may exist fully; With screw rod that its ease-to-operate of method that battery electrode column is connected with brace or connecting line is suitable, the very little no potential safety hazard of contact resistance can not influence battery capacity, cycle performance and fail safe in use.
