Description

Binding post and battery using same Technical Field The utility model relates to the technical field of battery terminals, in particular to a wiring terminal and a battery using the same. Background Currently, more than 60% of electric two-wheeled vehicles on the market are still using lead-acid batteries. The battery has the advantages of mature technology, low cost and the like, and takes the leading position of the battery market of the electric two-wheel vehicle for a long time. However, it is not neglected that lead-acid batteries have a number of safety hazards, and the problem of weak fixed installation is particularly pronounced. In the actual use process, due to complex urban road conditions, bumpy road conditions such as pits, speed reduction zones and the like are frequent, and in addition, the design of a part of battery fixing devices is unreasonable when the vehicles leave the factory, or the lead-acid batteries are automatically refitted at the later period of users to cause irregular installation, so that the lead-acid batteries are easy to shake in the running process of the vehicles. Once the terminal loosens due to jolt, the circuit connection is unstable, and the instantaneously generated electric spark is very likely to ignite combustible gas or peripheral inflammable matters in the battery, so that serious accidents of the ignition and burning vehicle are caused. Disclosure of utility model The inventor aims at the defects in the prior art, and provides a wiring terminal with reasonable structure and a battery using the same, wherein the contact area between the wiring terminal and the battery is increased by adding convex points on a grounding plate and concave parts on a pole, so that the contact performance is improved, and the wiring terminal is not easy to deform to generate loosening and burn when the wiring terminal is subjected to external force. The technical scheme adopted by the utility model is as follows: The utility model provides a binding post, includes mutual ground connection piece, battery ground connection position, the ground connection piece is equipped with the bump towards battery ground connection position one side, and battery ground connection position is equipped with the pit towards ground connection piece one side, and pit, bump form locking structure. As a further improvement of the above technical scheme: The grounding piece comprises an annular part and wire pressing pins led out of the annular part, and the salient points are arranged on one side of the annular part. The salient points are arranged on the annular part in a circumferential array or symmetrically, and the salient points are used for preventing circumferential movement of the grounding piece. The convex points are round points. The convex points are arranged in a truncated cone shape, and the top ends of the convex points are planes. The wire pressing pins and the salient points are respectively positioned at two sides of the grounding piece. The battery grounding position is arranged on the battery and is wound on the circumference of the pole of the battery. The battery ground is connected with the pole. The locking nut is arranged on the pole to press the grounding plate and the battery ground. A lead acid battery employing a terminal as defined in any one of the preceding claims.
