In general, a vehicle power source uses a battery, and the battery can be continuously used through charging, and the battery must be quickly charged every time it is used.

Typically, the vehicle is provided with an alternator which supplies current instead of the battery. The alternator is driven by a crank pulley with a V-belt, small size and light weight, high output, low consumption parts and excellent mechanical durability.

The alternator has a rectifier assembly installed therein and will be described with reference to the drawings.

Referring to FIG. 1, the rectifier assembly 1a includes an insulator 40, a heat sink 20 in close contact with the lower side of the insulator 40, and a terminal (not shown). In addition, the heat sink 20 is provided with a three-phase or six-phase diode (2).

Conventional rectifier assembly (1a) has a separate support member (40a) for supporting the stud bolt 10 on the left and right sides of the insulator 40 for the temporary assembly of the stud bolt 10, the heat A separate hook 40b is formed to be coupled to the sink 20 to maintain the state of being coupled to the heat sink 20.

When the stud bolt 10 is inserted, the support member 40a is preassembled in a state where the threaded portion is partially fitted and maintained temporarily until it is finally fixed by the nut.

However, in the conventional rectifier assembly configured as described above, when the six-phase diode is installed in the heat sink 20, it is difficult to form the support member 40a and the hook 40b described above in a limited space. There is a problem that (10) is separated to the outside before the nut is coupled.

The insulator 200 is provided with a plurality of diodes 2, and the stud bolts 10 are also installed.

The terminal 300 has a terminal 2a formed in the diode 2 inserted therein, and is provided for supplying the alternating current power through the diode 2 to the alternator or for electrical connection.

The heat sink 100 has at least three or six phase diodes 2 coupled thereto, and a plurality of diodes inserted along the circumferential direction with respect to the center of the heat sink 100 for coupling the diodes 2 are inserted. Holes 102 are formed.

The greatest feature of the present invention enables stable installation of the diode (2) even when a plurality of diodes (2) is installed in the insulator 200, and at the same time to keep the stud bolt (10) in a temporary pre-assembled state It is characterized by. To this end, the insulator 200 includes a fixing protrusion 122 formed in the opening hole 110 formed at a position spaced apart from the diode insertion hole 102. The fixing protrusion 122 is a member formed to fix the stud bolt 10 and is installed to face each other on both sides of the opening hole 110 and the head after the stud bolt 10 is inserted into the opening hole 110. 11) In contact with the upper surface to maintain the temporary fixing state of the stud bolt (10).

The fixing protrusion 122 according to an embodiment of the present invention is formed in a predetermined size and the top surface is pressed and deformed by a staking process after the stud bolt 10 is inserted into the opening hole 110. Due to the close contact with the head 11 of the stud bolt 10 to prevent the separation of the stud bolt 10 until the nut is coupled. For reference, the stacking process refers to a method of compressing by pressing the upper surface with a predetermined pressure to the structure of the protrusion-like structure.
