To defective of the prior art, the purpose of the utility model provides a kind of terminal box of utilizing trough of belt sheet metal welding diode.
According to an aspect of the utility model, a kind of terminal box of utilizing trough of belt sheet metal welding diode is provided, comprise terminal block housings, binding post, diode, cable connector; It is characterized in that, also comprise the outer fin of sheet metal, heat-conduction part and shell in the shell, wherein; Sheet metal is arranged on the inwall of said terminal block housings in the said shell; The outer fin of said shell is arranged on the outer wall of said terminal block housings, and said terminal block housings is provided with through hole, and said heat-conduction part is positioned at said through hole; Sheet metal connects the outer fin of said shell through heat-conduction part in the said shell; Be connected with the weld metal sheet on the said binding post, said weld metal sheet is provided with groove, and the pin of said diode is welded in the said groove.
Preferably, sheet metal is arranged on the inwall away from said terminals and diode of said terminal block housings in the said shell.
Preferably, said groove is a V-shaped groove.
The utility model is through connecting the weld metal sheet on binding post; On the weld metal sheet, groove is set then; Thereby can the pin of diode be welded in the said groove, thereby improve the intensity that diode is installed, make that the maintenance rate of terminal box reduces, reliability improves.
Description of drawings
Through reading the detailed description of non-limiting example being done with reference to following accompanying drawing, it is more obvious that the other features, objects and advantages of the utility model will become:
Fig. 1 illustrates the structural representation according to the terminal box of utilizing trough of belt sheet metal welding diode of the utility model;
Fig. 2 illustrates according to the pin of the diode in the terminal box of utilizing trough of belt sheet metal welding diode of the utility model and the annexation sketch map between the weld metal sheet.
Embodiment
The trough of belt sheet metal that utilizes that provides according to the utility model welds the terminal box of diode; Comprise terminal block housings 1, binding post 5, diode 6, cable connector 8; Also comprise the outer fin 4 of sheet metal 2, heat-conduction part 3 and shell in the shell; Wherein, sheet metal is arranged on the inwall 12 of said terminal block housings in the said shell, and the outer fin of said shell is arranged on the outer wall 11 of said terminal block housings; Said terminal block housings is provided with through hole; Said heat-conduction part 3 is positioned at said through hole, and sheet metal connects the outer fin of said shell through heat-conduction part in the said shell, thereby heat successively is transmitted in the air through the outer fin 4 of sheet metal 2, heat-conduction part 3 and shell in said.
More particularly, sheet metal is arranged on the inwall away from said terminals and diode of said terminal block housings in the said shell, and is as shown in Figure 1.Be connected with weld metal sheet 61 on the said binding post, said weld metal sheet is provided with groove 610, and the pin 60 of said diode is welded in the said groove, and said groove is V-shaped groove, and is as shown in Figure 2.
More than the specific embodiment of the utility model is described.It will be appreciated that the utility model is not limited to above-mentioned specific implementations, those skilled in the art can make various distortion or modification within the scope of the claims, and this does not influence the flesh and blood of the utility model.
