[0022] like Figure 1-4 As shown, it is the first embodiment of the utility model, which provides a rectifier diode, including a support plate 1, fixing holes 2 are opened on both sides of the top of the support plate 1, a heat dissipation mechanism 3 and a rectifier mechanism 5 are arranged on the top of the support plate 1, a wiring mechanism 4 is arranged on the top of the heat dissipation mechanism 3, the heat dissipation mechanism 3 includes a protective shell 31, the front and back sides of the inner cavity of the protective shell 31 are fixedly connected with a heat absorbing plate 32, a heat dissipation plate 33 is arranged on the side of the heat absorbing plate 32 away from the protective shell 31, and heat dissipation ports 34 are opened on the front and back sides of the protective shell 31.

[0023] like Figure 1 , 2 As shown in FIG. 3 , the heat sink 33 is used to absorb the temperature of the inner cavity of the protective shell 31, and the absorbed temperature can be transferred to the heat absorbing plate 32. The temperature stored on the heat absorbing plate 32 is transferred to the outside of the protective shell 31 through the heat dissipation port 34. The cooperation of the heat absorbing plate 32, the heat sink 33 and the heat dissipation port 34 enables the temperature generated by the rectifier mechanism 5 to be absorbed and processed, thereby achieving the effect of dissipating the heat generated when the rectifier mechanism 5 is in operation, thereby greatly improving the performance and service life of the rectifier diode body.

[0024] Example 2

[0025] Reference Figure 1 and 2 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0026] In this embodiment, the wiring mechanism 4 includes a wiring slot 41 , the back of the inner cavity of the wiring slot 41 is movably connected to a wiring board 42 via a hinge, and a wiring port 43 is provided on the surface of the wiring board 42 .

[0027] The wiring mechanism 4 further includes a contact slot 44 , and the contact slot 44 is disposed at the bottom of the inner cavity of the wiring slot 41 , and a conductive nut 45 is movably connected to the inner cavity of the contact slot 44 .

[0028] like Figure 1 and 2 As shown, the external wire can be connected to the conductive nut 45, so that the wire transmits current and voltage with the cooperation of the conductive nut 45 and the contact slot 44, providing basic preparation for the operation of the rectifier mechanism 5. The terminal block 42 covers the conductive nut 45 placed in the contact slot 44 to prevent the conductive nut 45 from falling from the contact slot 44. The cooperation of the terminal block 42, the contact slot 44 and the conductive nut 45 realizes the packaging simplification of the wiring of the rectifier diode, making the wiring operation more convenient to install.

[0029] Example 3

[0030] Reference Figure 4 , which is the third embodiment of the utility model, and this embodiment is based on the above two embodiments.

[0031] In this embodiment, the rectifying mechanism 5 includes a ceramic substrate 51 , and the bottom of the ceramic substrate 51 is fixedly connected to the support plate 1 , the top of the ceramic substrate 51 is provided with a rectifying assembly 52 , and the top of the support plate 1 is provided with a fixing mechanism 53 .

[0032] The rectifier assembly 52 includes a rectifier element 521 and a contact piece 522 , and both the rectifier element 521 and the contact piece 522 are fixedly connected to the ceramic substrate 51 . The rectifier element 521 includes a flow chip, a welding piece, a pin, a rectifier bridge, and the like.

[0033] The fixing mechanism 53 includes a fixing plate 531, a first threaded hole 532 is formed on the surface of the fixing plate 531, and second threaded holes 533 are formed on the front and back sides of the protective shell 31. The fixing mechanism 53 also includes a second threaded bolt 534, and one end of the second threaded bolt 534 passes through the second threaded hole 533 and extends to the inner cavity of the first threaded hole 532 and is threadedly connected to the inner cavities of the second threaded hole 533 and the first threaded hole 532.

[0034] like Figure 4 As shown, the ceramic substrate 51 is used to insulate the rectifying element 521 and the contact piece 522. The cooperation between the rectifying element 521 and the contact piece 522 realizes the conversion of the AC signal into a DC signal. The second threaded bolt 534 can be screwed into the inner cavity of the second threaded hole 533 and the first threaded hole 532, completing the fixing and unlocking effect of the support plate 1 and the heat dissipation mechanism 3, thereby realizing the effect that the heat dissipation mechanism 3 and the rectifying mechanism 5 can be easily disassembled and separated.

[0035] When in use, the wire can pass through the wiring port 43 and contact the conductive nut 45, so that the wire can transmit the current to the rectifying mechanism 5 for operation with the help of the conductive nut 45 and the contact groove 44. When the current is transmitted to the rectifying mechanism 5, the rectifying element 521 operates, and the rectifying element 521 generates a large amount of heat. Since the rectifying element 521 is located in the inner cavity of the protective shell 31, the heat generated by the rectifying element 521 will accumulate in the protective shell 31. At this time, the heat dissipation plate 33 can absorb the heat generated by the rectifying element 521, and the heat absorbed by the heat dissipation plate 33 The heat will be transmitted and introduced into the heat absorbing plate 32, and the heat dissipation port 34 further dissipates the heat generated on the heat absorbing plate 32, so that the heat on the heat absorbing plate 32 is transmitted to the outside of the protective shell 31 for heat dissipation, so that the rectifier element 521 can be discharged in time when it is heated, and the heat will not accumulate in the protective shell 31. The temperature in the protective shell 31 is controlled, and the rectifier element 521 will not be broken down and damaged by the heat. By performing heat dissipation operation on the rectifier element 521, the voltage and current stability of the rectifier element 521 during operation is guaranteed, thereby effectively reducing the failure rate of the rectifier element 521.
