Abstract
The utility model discloses an anti-loose external storage battery combined terminal which comprises a positioning plate, a terminal bolt and a terminal nut, wherein a welding hole is formed in one end of the positioning plate, and a connecting hole, the diameter of which is matched with the external diameter of the terminal bolt and which is connected with the terminal bolt, is formed in the other end of the positioning plate; the terminal nut is screwed on the terminal bolt; a groove is formed in the circumferential wall of the upper end of a threaded hole A in the terminal nut, and an antiskid sleeve is placed in the groove; a threaded hole B is formed in the internal diameter of the antiskid sleeve and the diameter of the threaded hole B is smaller than the external diameter of the terminal bolt. The anti-loose external storage battery combined terminal is great in practicality, has a fool-proof method, and can avoid misoperation. After the terminal bolt and the terminal nut are locked, the terminal bolt is in interference fit with the internal thread of the antiskid sleeve. The antiskid sleeve has a vibration buffer effect and antiskid performance and can effectively prevent poor contact, heating and even risk of striking a fire of the terminal caused by the fact that the terminal and the connecting head are loosened.
Description
Technical field
The utility model relates to storage battery field, is specifically related to a kind of anti-loosening external battery terminals of a unit block.
Background technology
Terminal is the important component part of storage battery, also be the only way which must be passed that connects external loading, terminal adopts female thread structure substantially at present, with bolt shimming and spring shim, locks terminal, and pad and spring shim mainly play the anti-skidding effect of bolt, but time and because of operating personnel carelessness, neglected loading pad and spring shim, and electric automobile drives storage battery to shake together in running, also easily causes terminal junction loosening, cause termination contact bad, heating even sparking is caused danger.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of anti-loosening external battery terminals of a unit block, practical, terminal nut is connected and has skid resistance with terminal bolt, effectively prevents that terminal and connector are loosening, causes that termination contact is bad, heating is even struck sparks, and calamity is caused danger.
The utility model is achieved through the following technical solutions:
A kind of anti-loosening external battery terminals of a unit block, comprise location-plate, terminal bolt and terminal nut, described location-plate one end is provided with welding hole, the other end is provided with the connecting hole being connected with terminal bolt external diameter coupling, terminal nut is screwedly mounted on terminal bolt, and the A screwed hole upper end perisporium of described terminal nut is provided with groove, is placed with Anti-slip cover in groove, Anti-slip cover internal diameter is provided with B screwed hole, and B screwed hole is less than terminal bolt external diameter.
The further improvement project of the utility model is that described B screwed hole is less than terminal bolt external diameter 0.2-1.4mm.
The utility model further improvement project is, described Anti-slip cover top arranges punching press sealing, and punching press sealing internal diameter is greater than terminal bolt external diameter.
The utility model further improvement project is, described punching press sealing internal diameter is greater than terminal bolt external diameter 0.5-2mm, and punching press is sealed apart from terminal nut upper surface thickness 1-3mm.
The utility model more further improvement project be, described terminal bolt upper end external diameter is cylinder, terminal bolt lower end external diameter is provided with upper and lower two steps, below outer diameter of step mates rivet welding with connecting hole on location-plate and is connected.
The utility model further improvement project is, described terminal nut upper end external diameter is cylinder or rhombogen, and lower end is provided with boss.
The utility model further improvement project is that described Anti-slip cover material is rubber, polypropylene or nylon.
The utility model further improvement project is that described location-plate thickness is 0.8-5mm.
The utility model compared with prior art, has following obvious advantage:
The utility model is practical, there is fool proof method, can avoid misoperation, after terminal bolt and terminal nut check, terminal bolt and Anti-slip cover internal thread interference fit, Anti-slip cover has damping vibration effect, there is skid resistance, can effectively prevent that terminal and connector are loosening, cause termination contact bad, heating even sparking is caused danger.
