Referring to fig. 1 and 2, a battery terminal 100 according to an embodiment of the present invention includes a main body 10, a wire connecting cylinder 20, two tightening arms 30, and a pressing member 40. The body 10 is ring-shaped and is broken at one point into a tightening opening B. The wire barrel 20 is disposed on an annular outer wall of the body 10, and a wire chamber C for accommodating a main wire harness (not shown) is configured therein. Two tightening arms 30 are respectively configured at both ends of the tightening slot B and extend in a direction away from the main body 10 with a space therebetween. The pressing member 40 includes a first fixing member 41, a lever 42, and a second fixing member 43. The rod member is disposed between the two tightening arms 30, the first fixing member 41 is disposed at the head of the rod member 42 and abuts against the peripheries of the two tightening arms 30, and the second fixing member 43 is screwed to the tail of the rod member 42. The surface of the first fixing member 41 abutting against the two tightening arms 30 is configured with a pressing slope F, and the surface of the two tightening arms 30 abutting against the pressing slope F is configured with a tightening slope S matching with the pressing slope F. When the second fixing member 43 is tightened with respect to the rod portion 42, the two tightening arms 30 approach each other to the tightening opening B by the cooperation of the pressing slope F and the tightening slope S.

When the battery terminal 100 is used, the main body 10 is sleeved on the battery electrode post, the second fixing member 43 is screwed, under the action of the second fixing member 43, the first fixing member 41 is close to the two tightening arms 30, the downward pressing inclined surface F is pressed downward relative to the tightening inclined surface S, so that the two tightening arms 30 are close to each other, and the tightening opening B is driven to be tightened until the main body 10 is stably fixed on the battery electrode post. Finally, the main electric connection harness is inserted into the electric connection barrel 20 to be pressed. Since the rod 42 passes through the two tightening arms 30 and the second fixing member 43 is located at one end of the rod 42, the operation plane is parallel to the end surface of the battery and will not collide with the battery body when tightening is performed, which is easy to operate. In addition, by providing the wire barrel 20, the main electric wire harness can be directly connected with the battery terminal 100, and the operation is simple and quick, and the use is convenient.

Specifically, each push-down slope F is inclined downward in a direction toward the rear of the head of lever 42 toward the direction approaching tightening arm 30. The force exerted by press-down ramp F on tightening ramp S is perpendicular to the ramp and may be generated as a component perpendicular to lever 42, which component is directed toward lever 42 when press-down ramp F is angled downward in a direction toward the tail of lever 42 toward tightening arm 30. The force components perpendicular to rod 42, which are generated by two pressing slopes F, are both directed toward rod 42, which pushes both tightening arms 30 toward rod 42, that is, both tightening arms 30 approach each other, so that tightening opening B is tightened.

More specifically, the first fixing member 41 includes a first section 411, a second section 412, and an intermediate section 413, the first section 411 and the second section 412 are disposed opposite to each other and both extend in the axial direction of the rod member 42, and the intermediate section 412 is connected between the first section 411 and the second section 412 in a direction intersecting with the axial direction of the rod member 42. First section 411 and second section 412 abut against the outer peripheries of two tightening arms 30, and the surfaces of the two tightening arms 30 facing each other are configured as pressing slopes F.

In some embodiments, the surfaces of the two tensioning arms 30 facing each other are each configured with a receiving recess R, which together form a receiving space for receiving a rod 42. Since rod 42 is located between two tensioning arms 30, it may hinder the approach of two tensioning arms 30, and if one wants to close tensioning arms 30 close enough, it is necessary to make rod 42 thin enough, but too thin a dimension may seriously affect the strength of rod 42, affecting the reliability of the connection. Therefore, the two receiving grooves R together form a receiving space to receive the rod member 42, so that the rod member 42 does not obstruct the approach of the two tightening arms 30, and even the two tightening arms 30 can be completely attached without being affected by the rod member 42.

In some embodiments, the battery terminal 100 further includes an insulating protective sleeve (not shown) that is sleeved on the connection portion of the main wiring harness and the wire barrel 20. The insulating sheath and the insulating layer of the main wiring harness are connected to each other by heating. The insulating protective sleeve can play a role in protecting and further reinforcing the connection between the main wiring harness and the wiring barrel 20, and rain erosion, electric leakage and the like caused by the fact that the connection position is exposed are avoided. The insulating protective sleeve is connected with the insulating layer of the main wiring harness through heating, so that the stability and the sealing performance of connection can be enhanced.

Further, the normally electric ear 50 includes an ear body 51 and a third fixing member (not shown), and the ear body 51 is provided with a threaded hole 511. The normally-connected harness end is provided with a circular lug, and the third fixing member passes through the circular lug and is detachably connected with the lug body 51 through the screw hole 511. The normally connected wire harness can be easily and stably electrically connected with the normally connected lug 50 by means of the circular lug of the terminal and the third fixing piece.

In some embodiments, the terminal barrel 20 and the normally conductive lug 50 are cast integrally with the main body 10. The wire connecting cylinder 20 and the normally-charged lug 50 are integrally arranged with the main body 10, so that the connection stability of the wire connecting cylinder 20 and the normally-charged lug 50 can be improved, good electrifying capacity can be guaranteed, and rapid mass production is facilitated.
