Further, described internal jacket one end is female end, and the described internal jacket other end is provided with the limb that can insert in external jacket; External jacket one end is the male end coordinated with female end, and the external jacket other end forms the conical inboard wall that can promote limb clamping external connection; Internal jacket and external jacket are provided with the bulge loop that can clamp box body.Described female end and male end can realize the firm connection of internal jacket and external jacket, and lobe folder can clamp external connection under the effect of external jacket, inside and outside chuck then can be clamped on box body by bulge loop, and then ensures the stability that external connection is connected with box body, and slip-off preventing is effective; And structure is simple, easily realizes.
Further, the bottom surface of described box body is provided with some parallel heat sink strips.Form heat dissipation channel between described heat sink strip, accelerate the flowing of air, and then accelerate the rate of heat exchange of inside and outside louvre, further increase the radiating effect of terminal box.
Further, described diode is provided with the second securing member be connected with contiguous block, and this second securing member connects box bottom through contiguous block.Described second securing member improves the fastness that diode is connected with contiguous block, and the speed of dismounting is faster.
In sum, inside and outside louvre of the present utility model then accelerates the radiating rate of box body, and ensure the result of use of terminal box, and inside and outside chuck can prevent external connection from coming off, the fastness of connection is good.
