Wherein, the threaded rod through fixed block is threaded on the fixed block, one end of the threaded rod is socketed with Curved splint.

Wherein, the radiating fin is provided with multiple altogether, and multiple radiating fins are parallel to each other, adjacent two radiating fin it Between spacing it is equal.

Wherein, there are two the cylindrical cavity opens up altogether, and vertical center line of two cylindrical cavities about limit plate Symmetrically.

Wherein, there are four the curved splint is arranged altogether, four curved splints are divided into two groups, and every group two, and four arcs Clevis plate is in same horizontal line.

In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:

1, in the utility model, rectifier ontology is directly bonded on heat-radiating substrate, and rectifier ontology and heat dissipation base Multiple radiating fins being parallel to each other, such structure setting, so that the heat that this body running of rectifier generates are welded between plate Amount can also be radiated by heat-radiating substrate transmission radiating in the air by radiating fin diverging, effective to improve Its efficiency to radiate increases its service life.

2, in the utility model, it is connected with the conducting wire through limit plate on rectifier ontology, is provided with screw thread on limit plate The curved splint that bar drives it to move, can fix conducting wire by curved splint, so that conducting wire and rectifier sheet Body junction will not ensure that the stability that conducting wire is connect with rectifier ontology there is a phenomenon where pulling and being bent.

3, in the utility model, the other end of conducting wire is connected with connector lug, and rectifier ontology is allowed to pass through connector lug It is connected in terminal box, carries out conducting wire connection, it is very convenient, convenient for its installation and removal, and it is provided on connector lug self-locking Bar, after the completion of connector lug is clamped, self-lock rod is closed under the action of the spring, and the wiring of connector lug connection is fastened on by fixture block On box, connector lug and the self-locking fixation of terminal box are completed, improves the stability of connector lug connection.
