Abstract
The utility model provides a battery electrode connecting screw, includes the screw cap and the lead screw of being connected with the screw cap, the lead screw includes upper boom and lower beam, the diameter of upper boom is greater than the diameter of lower beam, the upper boom includes the threaded rod of being connected with the lower beam and the smooth pole of being connected with the screw cap. The lower end of the screw rod is not provided with threads, the diameter of the lower end of the screw rod is smaller than that of the upper portion of the screw rod, the lower end of the screw rod cannot damage threads in the top cover after the screw is screwed, the screw can be protected, and the service life of the screw is prolonged.
Description
The technical field is as follows:
the utility model belongs to the screw field mainly relates to a battery electrode connecting screw.
Background art:
the utmost point post of some batteries is shorter, often remove utmost point post through the screw, and then extend the casing outside, after the battery assembly finishes, need carry out the charge-discharge process to the battery, and the screw on this moment utmost point post is prepared for the battery charge-discharge, need cyclic utilization, the screw is convenient for the clip centre gripping simultaneously, however, current threadiness all covers the bottom due on the lead screw of screw, and under the condition of the screw of screwing, the threadiness of screw lower extreme can receive brokenly gradually, simultaneously, the lower extreme internal thread in the top cap also can receive the harm, but screw lower extreme threadiness is destroyed, this screw just can not reuse so, cause and scrap.
The utility model has the following contents:
in order to overcome the defects, the utility model provides a storage battery electrode connecting screw.
The utility model provides a technical scheme that its technical problem adopted:
the utility model provides a battery electrode connecting screw, includes the screw cap and the lead screw of being connected with the screw cap, the lead screw includes upper boom and lower beam, the diameter of upper boom is greater than the diameter of lower beam, the upper boom includes the threaded rod of being connected with the lower beam and the smooth pole of being connected with the screw cap.
And a chamfer angle is arranged at the joint of the lower rod and the threaded rod.
The thickness of screw cap is 3.4mm, the length of smooth rod is 4.5mm, the length of screw rod is 8.6mm, the length of lower rod is 2.5 mm.
Due to the adoption of the technical scheme, the utility model discloses have following superiority:
the utility model provides a pair of battery electrode connecting screw, the lead screw lower extreme does not have the silky texture to lead screw lower extreme diameter is less than upper portion, guarantees the screw back of screwing, and the lead screw lower extreme can not cause the damage to the screw thread in the top cap, also can protect the screw equally, improves the life of screw.
Description of the drawings:
fig. 1 is a schematic view of the overall structure of the present invention;
in the figure: 1. a screw cap; 2. a smooth rod; 3. a threaded rod; 4. a lower rod; 5. and (5) putting the rod on.
The specific implementation mode is as follows:
the present invention will be explained in more detail by the following examples, which are intended to protect all the changes and improvements within the scope of the present invention, and are not limited to the following examples;
combine the attached drawing a battery electrode connecting screw, including the screw cap and with the lead screw that the screw cap is connected, the lead screw includes upper boom and lower beam, the diameter of upper boom is greater than the diameter of lower beam, the upper boom includes the threaded rod of being connected with the lower beam and the smooth pole of being connected with the screw cap.
And a chamfer angle is arranged at the joint of the lower rod and the threaded rod.
The thickness of screw cap is 3.4mm, the length of smooth rod is 4.5mm, the length of screw rod is 8.6mm, the length of lower rod is 2.5 mm.
When in use, the utility model is screwed into the threaded hole of the top cover, and the diameter of the lower rod is smaller than that of the upper rod, so the lower end of the screw can not contact with the side wall of the lower end of the threaded hole of the top cover and the thread can not be damaged; even the screw bottom contact utmost point post, after screwing the screw, because the screw thread of screw is in the middle part position of whole screw, if the screw continues to screw, the screw thread on the threaded rod still can rotate with the screw-thread fit on the top cap, can not lead to the fact the damage to the screw thread on the screw or the internal thread of top cap.
The details of the above are not described in detail since they are prior art.
