Abstract
The invention is a connection method for power batteries with male thread type terminal posts. According to the invention, terminal posts and connection sheets are tightly connected by a specially designed screw-sleeve connection method of combining sleeves and screws so as to achieve a series-parallel effect, and glue is applied where the connection sheets and the terminal posts contact to prevent the two from loosening. The greatest characteristic of the invention is that conventional the plane contact between terminal posts and connection parts is changed, and more reliable thread contact flank with larger contact area is employed; therefore, effective contact area is enlarged and potential safety hazard resulting from uneven planes is eliminated.
Description
Technical field
The present invention relates to a kind of batteries packing technique, be specifically related to a kind of power type accumulator battery external screw thread formula pole method of attachment that is used for.
Background technology
Motive-power battery with external screw thread formula pole commonly used connected mode when carrying out the connection in series-parallel connection is that brace is directly fastening with nut.This kind mode is simple to operate, only needs to use simple tools (spanner) can finish whole connection procedure.It mainly is exactly to adopt this mode that the pole connection of the motive-power battery of external screw thread formula pole is arranged at present.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 nut and brace and brace and pole bottom platform partly contact.On the one hand, effective contact area of nut is less, and on the other hand, used usually external screw thread formula pole is thicker, and its terrace part is also less, therefore causes whole effective contact area less, makes that the connection internal resistance is bigger.
2. work as nut, 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 or even put contact from whole face contact becoming part face contact, it is a lot of greatly that the contact internal resistance of this moment more normally contacts internal resistance, to cause pole overheated when serious, thus the potential safety hazard of causing.
Therefore, adopting brace at present more than directly is not the desirable connected mode of external screw thread formula pole battery with the fastening mode of nut.
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 external screw thread formula pole.
The technical solution used in the present invention is: a kind ofly be used to have the method for attachment of external screw thread formula pole motive-power battery, it is characterized in that: may further comprise the steps:
1) makes a connecting screw rod cover, this connecting screw rod cover comprises the polygon sleeve that conveniently turns that is threaded the hole of end sealing, the sleeve blind end is a screw rod, and its hand of spiral is opposite with sleeve inside spin direction, and the length of reverse thread is consistent with internal thread of sleeve;
2) make the connecting elements that overlaps the connector in the band left-hand thread hole that an end is complementary with connecting screw rod;
3) spring shim is placed on first battery electrode column, another spring shim is placed on the screw rod of connecting screw rod cover;
4) connecting screw rod is overlapped socket end and aim at first battery electrode column, the screw rod end is aimed at the screwed hole of connector;
5) tool using turns the sleeve of connecting screw rod cover until tightening;
6) carry out the anti-loosening processing of a glue at connector and screw flight contact position;
7) identical for the connection of second battery electrode column with above-mentioned first battery electrode column, realize that finally external screw thread formula 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 external screw thread formula structure pole battery.
The present invention at first correctly places spring shim, screw rod cover socket end is aimed at battery electrode column then, the other end is aimed at the screwed hole of brace, battery electrode column and brace progressively closely link to each other with the screw rod cover when turning sleeve, it are 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 battery with external screw thread formula pole.
The sleeve that the present invention adopts particular design closely couples together pole and brace with the method that the screw rod cover that screw rod combines is connected, thereby reaches series-parallel effect, carries 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 attachment security hidden danger 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.
