Abstract
The invention discloses a heat dissipating structure for connecting terminals, which comprises connecting terminals, springs, supporting pieces, diodes and a mounting plate. The connecting terminals and the springs are abreast installed on the mounting plate. Each connecting terminal corresponds to one supporting piece. The supporting piece presses the connecting terminal and the spring corresponding to the supporting piece and then is clamped on the mounting plate. The diodes are installed between every two adjacent connecting terminals. One of the corresponding connecting terminal and the supporting piece in each group is connected with a heat dissipating arm or two of the corresponding connecting terminal and the supporting piece are not connected with the heat dissipating arm. Since the heat dissipating arm can be selectively installed or not installed on the connecting terminal or the supporting piece, the materials of the supporting pieces and the heat dissipating arms can be selected and free matching can be conducted, all kinds of heat dissipation levels can be set and requirements on all kinds of heat dissipation are satisfied.

Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further.
Embodiment one
As shown in Figure 1, present embodiment comprises splicing ear 1 and spring 1a, strutting piece 2, diode 3 and mounting panel 4.A plurality of (present embodiment is 4) splicing ears 1 and spring 1a are installed on the mounting panel 4 side by side, each splicing ear 1 corresponding strutting piece 2, and strutting piece 2 is installed on the mounting panel 4 after pushing down splicing ear corresponding with it 1 and spring 1a.Between each adjacent splicing ear 1 diode 3 is installed.Four splicing ears 1, four strutting pieces 2 are not with the heat radiation arm, and the two ends frame of diode 3 is on spring 1a, and the shell of diode 3 is in vacant state.In the present embodiment, splicing ear 1 is a metal material, and strutting piece 2 is metal material or plastic material.
Embodiment two
As shown in Figure 2, present embodiment comprises splicing ear 1 and spring 1a, strutting piece 2, diode 3 and mounting panel 4.A plurality of (present embodiment is 4) splicing ears 1 and spring 1a are installed on the mounting panel 4 side by side, each splicing ear 1 corresponding strutting piece 2, and strutting piece 2 is installed on the mounting panel 4 after pushing down splicing ear corresponding with it 1 and spring 1a.Between each adjacent splicing ear 1 diode 3 is installed.The both sides of two strutting pieces 2 in centre except that two ends respectively are connected with a heat radiation arm 2a, and the shell of diode 3 is close on two adjacent heat radiation arm 2a.In the present embodiment, strutting piece 2 is metal material or plastic material, and heat radiation arm 2a is a metal material.When strutting piece 2 was metal material with heat radiation arm 2a, both riveted or are injected into one mutually; When strutting piece 2 is a plastic material, when heat radiation arm 2a was metal material, both riveted mutually.
Embodiment three
As shown in Figure 3, present embodiment comprises splicing ear 1 and spring 1a, strutting piece 2, diode 3 and mounting panel 4.A plurality of (present embodiment is 4) splicing ears 1 and spring 1a are installed on the mounting panel 4 side by side, each splicing ear 1 corresponding strutting piece 2, and strutting piece 2 is installed on the mounting panel 4 after pushing down splicing ear corresponding with it 1 and spring 1a.Between each adjacent splicing ear 1 diode 3 is installed.The both sides of four strutting pieces 2 respectively are connected with a heat radiation arm 2a, and diode 3 shells are close on two adjacent heat radiation arm 2a.In the present embodiment, strutting piece 2 is metal material or plastic material, and heat radiation arm 2a is a metal material.When strutting piece 2 was metal material with heat radiation arm 2a, both riveted or are injected into one mutually; When strutting piece 2 is a plastic material, when heat radiation arm 2a was metal material, both riveted mutually.
