Abstract
The invention discloses a method for connecting external thread type posts of a power battery. The method comprises the following steps of: firstly, penetrating a conducting wire through two fastening sleeves, wherein two ends of the conducting wire are connected with two taper joints respectively; secondly, placing the taper joints into taper holes corresponding to the posts, and rotating the fastening sleeves to ensure that the taper joints closely contact the posts; and finally, performing dispensing looseness-prevention treatment on threaded parts where the fastening sleeves are connected with the posts or on upper surface holes of the fastening sleeves to fulfill the aim of preventing looseness. The method is simple in process and is convenient to operate, and by adoption of the method, complex equipment is not needed, the connection internal resistance between battery packs can be greatly reduced, and the hidden trouble of poor contact can be eliminated, so that the method is an ideal assembling mode for batteries provided with the external thread type posts. The method for connecting the posts is suitable for connecting the batteries provided with the external thread type posts.
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 accomplish 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 is following problem in this mode in application:
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 scheme that the present invention adopts is:
The present invention adopts the fastening method of sleeve that pole and the taper joint that has connected with lead are in advance closely coupled together, thereby reaches series-parallel effect, and anti-loosening processing is carried out in the screw thread place's point gluing that contacts with pole at fastening sleeve at last.The simple plane contact that its biggest characteristic is not only to remain with traditional approach between pole and the connector and is had; But also make full use of the pole inner space; Adopt the contact of interior tapered face, this way has also been eliminated out-of-flatness and the issuable potential safety hazard on plane when having increased effective contact area greatly.
A kind ofly be used for the method for attachment of power type accumulator battery external screw thread formula pole, may further comprise the steps:
(1) makes two external screw thread poles that have bellmouth;
(2) make two with the suitable corresponding taper joint of pole bellmouth, the pole bellmouth is consistent with the taper surface tapering of taper joint;
(3) make two up/down perforations and the inner fastening sleeve that is provided with screw thread, the external screw thread of fastening sleeve internal whorl and pole is suitable;
(4) use one to connect lead and pass two fastening sleeves simultaneously, the two ends that connect lead are connected with at the bottom of the awl of two taper joints respectively;
(5) two taper joints are inserted respectively in the bellmouth of two poles;
(6) external screw thread through fastening sleeve internal whorl and pole rotates fastening sleeve and pole is fastenedly connected with instrument;
(7) carry out the locking processing of a glue at the place, upper surface hole of screw thread place that fastening sleeve is connected with pole and fastening sleeve.
As preferably, said fastening sleeve and taper joint are cast member.
As preferably, adopt soldering between said connection lead and the taper joint or use the trunk mechanical connection.
As preferably, the taper surface angle of said taper joint is less than 30 degree.
The present invention at first passes lead with two fastening sleeves; The lead two ends connect two taper joints more respectively; Then taper joint is placed in the bellmouth of corresponding pole; Rotate fastening sleeve and make and closely contact between taper joint and pole, perhaps locate to carry out the locking processing of a glue and it is reached prevent the purpose become flexible in the upper surface hole of fastening sleeve through the screw thread place that is connected with pole at fastening sleeve 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.
Pole method of attachment among the present invention is applicable to the connection with external screw thread formula structure pole battery.
Beneficial effect:
1. the present invention adopts the taper joint connection can replace existing brace to connect the assembling that is used for motive-power battery, satisfies each item performance requirement of electrokinetic cell, but also has greatly reduced the contact internal resistance;
2. technology of the present invention has been eliminated brace fully and has been connected the attachment security hidden danger that possibly exist;
3. adopt that bellmouth connects to be connected its ease-to-operate suitable with traditional brace, the little no potential safety hazard of contact resistance can not influence battery capacity, cycle performance and fail safe in use.
