Abstract
The utility model discloses an internal thread type polar column connecting device of a dynamical type storage battery. An internal threaded hole is formed in a polar column, and the polar column connecting device comprises a connecting screw rod and a connecting device. A polygonal bump is arranged in the middle of the connecting screw rod. A first threaded part and a second threaded part are respectively arranged on two sides of the polygonal bump. The first threaded part is opposite to the second threaded part in thread direction. Threaded holes are formed at two ends of the connecting piece. The first threaded part is in matched connection with the threaded holes and the second threaded part is in matched connection with the internal thread of the polar column. According to the internal thread type polar column connecting device of the dynamical type storage battery, through specially designed screw connection, the polar column is no longer flatly contacted with the connecting device but contacted with the connecting device via multiple circles of threads. Thus, the contact area and contact reliability are greatly increased. The requirements on surface evenness and smoothness of the polar column of the battery are reduced through the connecting manner, the contact internal resistance is greatly reduced, and the contact reliability is improved.
Description
Technical field
The utility model belongs to storage battery assembling field, is specifically related to a kind of power type accumulator battery I.S.S pole jockey.
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 instrument (spanner) can finish whole connection procedure.The pole connection that has at present the motive-power battery of I.S.S pole 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 so that the contact internal resistance is larger.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, so that it is larger to connect internal resistance.
2, when bolt, brace, pole terrace part Three regions 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 the integral face contact, it is much larger 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, need a kind of new power type accumulator battery I.S.S pole jockey to address the above problem.
The utility model content
The utility model purpose: the utility model provides a kind of power type accumulator battery I.S.S pole jockey of stable connection for the defective of the motive-power battery fastening means of I.S.S pole in the prior art.
Technical scheme: for solving the problems of the technologies described above, power type accumulator battery I.S.S pole jockey of the present utility model adopts following technical scheme:
A kind of power type accumulator battery I.S.S pole jockey, described pole is provided with internal thread hole, described pole jockey comprises connecting screw rod and brace, the middle part of described connecting screw rod has the polygon boss, the both sides of described polygon boss are respectively arranged with the first threaded portion and the second threaded portion, the hand of spiral of described the first threaded portion is opposite with the hand of spiral of described the second threaded portion, the two ends of described jockey are provided with screwed hole, described the first threaded portion and described screwed hole are connected, and the internal thread hole of described the second threaded portion and described pole is connected.
Beneficial effect: power type accumulator battery I.S.S pole jockey of the present utility model has changed only to contact by two surfaces between brace and pole in traditional internal thread pole connected mode and has caused the larger disadvantage of contact resistance, screw rod by particular design connects, it no longer is plane contact between pole and the brace, but by the contact of multi-turn screw thread, contact area and contact reliability have so just greatly been increased, and this connected mode has reduced the requirement to battery electrode column surface smoothness degree smoothness, greatly reduced the contact internal resistance, and improved contact reliability.This motive-power battery for the large electric current high-multiplying power discharge of need is most important.

Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
See also Fig. 1, Fig. 2 and shown in Figure 3, power type accumulator battery I.S.S pole jockey of the present utility model, wherein, pole 1 is provided with internal thread hole 11, and pole 1 brace 3 comprises connecting screw rod 2 and brace 3.Wherein, the middle part of connecting screw rod 2 has polygon boss 21, and the hand of spiral that the both sides of polygon boss 21 are respectively arranged with the first threaded portion 22 and 23, the first threaded portions 22, the second threaded portion is opposite with the hand of spiral of the second threaded portion 23.Wherein, polygon boss 21 is pentagon boss or hexagon boss.Thereby obtain that two ends of the present utility model have the opposite threads direction of rotation and middle screw rod with polygon boss 21 of convenient wrench or other tool operation.
The two ends of brace 3 are provided with screwed hole 31,32, the first threaded portions 22 are connected with screwed hole 31,32, and the second threaded portion 23 is connected with the internal thread hole 11 of pole 1.Connect by plate or bar between the screwed hole 31,32 of brace 3.Concrete operation method is: connecting screw rod 2 one ends are aimed at battery electrode column 1 internal thread hole 11, and the other end is aimed at the screwed hole 31,32 of brace 3, and battery electrode column 1 progressively closely links to each other with connecting screw rod 2 two ends with brace 3 when turning boss.The utility model has changed in traditional internal thread pole 1 connected mode brace 3 and has only contacted by two surfaces with 1 of pole and cause the larger disadvantage of contact resistance, screw rod by particular design connects, no longer be plane contact between pole 1 and the brace 3, but by the contact of multi-turn screw thread, contact area and contact reliability have so just greatly been increased, and this connected mode has reduced the requirement to battery electrode column 1 surface smoothness degree smoothness, greatly reduce the contact internal resistance, and improved contact reliability.This motive-power battery for the large electric current high-multiplying power discharge of need is most important.Wherein, concrete, the distance between brace 3 screwed holes equates with distance between the pole 1.The quantity of screw rod is two.
