The utility model provides a binding post for battery, includes the terminal, the terminal includes the terminal body and locates terminal body top, has the stud section of external screw thread, step structure has between stud section and the terminal body, binding post for battery still include with stud section screw-thread fit's nut, the stud section is located part between step structure and the nut is used for external power source line. The binding post is the copper core structure of binding post, still need the casting to form the lead base part again when making the terminal, and the structure of lead base part is prior art, so does not describe in detail in this application again.

Preferably, the bottom end of the nut has a collar formed to extend outwardly.

Preferably, the top surface of the stud section is provided with a first clamping groove for locking, the top surface of the nut is correspondingly provided with a second clamping groove, and the wiring terminal for the storage battery further comprises a pin penetrating through the first clamping groove and the second clamping groove to lock the nut and the wiring terminal.

More preferably, the cross section of the slot is trapezoidal, and correspondingly, the cross section of the pin is also trapezoidal.

More preferably, a plurality of second clamping grooves are formed in the top surface of the nut at intervals.

Preferably, the bottom of the terminal body is provided with a casting section with a polygonal cross section, and the casting section is provided with a concave ring for increasing the contact area.

The utility model discloses binding post for battery designs the double-screw bolt section that has the external screw thread through the binding post with threaded connection formula, deuterogamies a nut, and internal screw thread degree of depth all detects more easily on the external screw thread degree of depth of screw bolt section and the nut like this, is favorable to control quality.

Detailed Description

As shown in fig. 1-4, a binding post for battery, including terminal 1, terminal 1 includes terminal body 11 and locates terminal body 11 top, has the double-screw bolt section 12 of external screw thread, has stair structure 13 between double-screw bolt section 12 and the terminal body 11, the utility model discloses binding post for battery still include with double-screw bolt section 12 screw-thread fit's nut 2, the part that double-screw bolt section 12 is located between stair structure 13 and the nut 2 is used for external power source line. The binding post 1 is binding post's copper core structure in this application, still need the casting again to form the lead base part when making the terminal, and the structure of lead base part is prior art, so no longer describes in detail in this application. When the power cord is externally connected, one end of the power cord is wound at the bottom of the stud section 12, then the nut 2 is screwed on the stud section 12, the power cord is compressed, and the connection of the power cord and the wiring terminal is completed.

The bottom end of the nut 2 is provided with a retaining ring 21 which extends outwards, and the retaining ring 21 is used for a power line externally connected with the retaining column to prevent the power line from being separated from the upper part.

In order to ensure that the nut 2 is not easy to loosen during use, the top surface of the stud section 12 is provided with a first locking groove 14 for locking, the top surface of the nut 2 is correspondingly provided with a second locking groove 22, and the locking is carried out through a pin 3 which penetrates through the first locking groove 14 and the second locking groove 22 to lock the nut 2 and the binding post 1. The second slots 14 may be arranged in pairs such that the pins 3 pass completely through both sides of the nut 2. The cross section of the clamping groove (including the first clamping groove 14 and the second clamping groove 22) can be trapezoidal, correspondingly, the cross section of the pin 3 is also trapezoidal, the trapezoid is small at the top and big at the bottom, and therefore after the pin 3 is locked, the pin is not easy to separate out, and the locking effect is ensured. Of course, the cross section of the pin 3 and the cross section of the slot may have other configurations as long as it is ensured that the pin 3 is not easily disengaged when locked. In order to lock the pin 3 without requiring an excessive angle of the nut 2, a plurality of second locking grooves 22 may be provided at intervals on the top surface of the nut 2, so that even if the angle of the nut 2 needs to be adjusted, it needs to be rotated by a small angle.

The bottom of the terminal body 11 has a casting section 15 having a polygonal cross section, and the casting section 15 is provided with a recessed ring 16 for increasing a contact area. When the binding post 1 is cast to form a lead base, the shape of the casting section 15 is designed to be polygonal, and the design of the concave ring 16 is added, so that the bonding strength between the binding post and the lead base is increased.

The utility model discloses binding post for battery designs the double-screw bolt section 12 that has the external screw thread through the binding post with threaded connection formula, and a nut 2 of deuterogamying, internal screw thread degree of depth all detects more easily on the external screw thread degree of depth of screw bolt section 12 and nut 2 like this, is favorable to control quality.
