A plurality of clip grooves 21 'are formed to which the clips 27 are coupled. Accordingly, the gap between the pair of nut members 22 is narrowed or widened when the tightening shaft 21 rotates in the forward or reverse direction.

In addition, the nut member 22 has an internal thread formed therein to which the external thread 21b of the tightening shaft 21 is fastened, and the fitting portion 22b coupled to the coupling hole 12 'formed in the elastic piece; A hole through which the tightening shaft 21 penetrates is formed, and is integrally formed with the fitting portion 22b, and includes a close contact portion 22a that is in close contact with the outer side of the elastic piece. In addition, the tightening bolt 23 is preferably provided with a cover (23 ') is formed convexly upwards and integrally coupled to the upper side of the head portion.

Referring to the operation of the connection terminal for a lever rotary battery of the present invention configured as described above are as follows.

When the connection terminal is to be installed in the storage battery, the terminal inserting portion 11 is coupled to the post terminal of the storage battery so that the extension part 11d of the lower inserting portion 11b is in close contact with the upper surface of the storage battery. Subsequently, the handle 26 of the lever member 24 protrudes from the receiving groove 24c to stand vertically, and then the lever member 24 is rotated in the forward direction using the handle 26. When the lever member 24 rotates in the forward direction, the tightening bolt 23 coupled to the lever member 24 rotates, and the worm screw 23a of the tightening bolt 23 is rotated according to the rotation of the tightening bolt 23. ), The tightening shaft 21 in which the worm gear 21a is engaged is rotated forward. Then, the gap between the pair of nut members 22 fastened to the tightening shaft 21 is narrowed to press the elastic pieces 12a, 12b, 12c of the elastic portion 12 to insert the terminal 11 ) To reduce the diameter. Therefore, the connection terminal is firmly coupled to the post terminal of the storage battery.

At this time, since the lever member 24 is coupled to the tightening bolt 23 via the clutch mechanism 25, the lever member 24 is within the angle range of the clutch groove 24b formed in the engaging portion 24a. Only rotated. That is, when the clutch protrusion 25c of the clutch ring 25b comes in contact with the end of the clutch groove 24b when the lever member 24 is rotated in the forward direction, the lever member 24 is no longer rotated. Will be.

Therefore, the lever member 24 should be rotated in the reverse direction so that the clutch protrusion 25c is located at the opposite end of the clutch groove 24b. While the lever member 24 is rotated in the reverse direction, the clutch mechanism 25 The tightening bolt 23 does not rotate by the clutch function. Thereafter, when the lever member 24 is rotated again in the forward direction, the tightening bolt 23 rotates together with the lever member 24.

Therefore, by repeating the above process it is possible to firmly couple the connection terminal to the post terminal of the battery. Since the tightening bolt 23 and the tightening shaft 21 are worm-coupled, the tightening shaft 21 does not rotate unless the tightening bolt 23 is rotated using the lever member 24. Thus, loosening due to rotation of the tightening shaft 21 is prevented.

Of course, when the connection terminal is to be separated from the post terminal of the battery, the lever member 24 may be rotated in the reverse direction, and each of the components may operate in the opposite direction. That is, the clutch mechanism 25 allows the tightening bolts 23 to rotate together only while the lever member 24 rotates in the reverse direction, and the tightening bolts using the clutch function while the lever member 24 rotates in the forward direction. By preventing the 23 from being rotated, the tightening shaft 21 is reversed so that the diameter of the terminal insertion portion 11 is enlarged.

As described above and described with reference to some embodiments for illustrating the technical idea of the present invention, the present invention is not limited to the configuration and operation as described above, it deviates from the scope of the technical idea described in the specification Those skilled in the art will appreciate that many modifications and variations can be made to the present invention without departing from the scope of the invention. And all such modifications and changes as fall within the scope of the present invention are therefore to be regarded as being within the scope of the present invention.
