Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-7, the present invention provides an insulation isolation connector, comprising: metal heat sink a 1;
an insulating sheet 6 is arranged between the metal radiator a1 and the metal radiator b2, a connector 3 is arranged on the surface of the insulating sheet 6 far away from the metal radiator a1, a nut 5 is embedded in the connector 3, and a screw 7 is screwed in the nut 5.
The structure of the connecting piece 3 can realize the tight attachment between the metal radiator a1 and the metal radiator b2 and ensure the safe insulation work between the nut 5 and the metal radiator b2, the nut 5 is embedded in the connecting piece 3, and the matching structure of the nut 5 and the metal radiator b2 can ensure that the nut 5 in the connecting piece 3 is just aligned with the screw 7 when the screw 7 is locked in the connecting piece 3, thus being beneficial to assembly and not needing to make a specific positioning jig for the connecting piece 3; the connecting piece 3 is integrally formed, and has simple structure and small occupied space.
In a preferred embodiment, the metal heat sink a1 and the metal heat sink b2 are attached to each other, and the metal heat sink a1 and the metal heat sink b2 are isolated from each other by the insulating sheet 6 and the connecting member 3.
As shown in fig. 7: since the nut 5 is connected to the metal heat sink a1 by the screw 7, it is necessary to ensure safe insulation between the nut 5 and the metal heat sink b 2; the connecting piece 3 is formed by integrally wrapping the insulating part 4 with the nut 5, the nut 5 is embedded, so that the insulation between the nut 5 and the metal heat radiator b2 can be ensured, and meanwhile, the metal heat radiator a1 and the metal heat radiator b2 can be tightly locked together through the screw 7 and the nut 5.
In a preferred embodiment, the metal heat sink a1 and the metal heat sink b2 are fixed by screws 7 and nuts 5.
The joint between the metal radiator a1 and the metal radiator b2 is mainly realized by the locking of the screw 7 and the nut 5; the combination of the insulating sheet 6 and the connecting member 3 between the metal heat radiator a1 and the metal heat radiator b2 fully ensures the electrical isolation and the safety isolation between the metal heat radiator a1 and the metal heat radiator b 2.
In a preferred embodiment, a screw hole is formed on the surface of the metal heat sink a1, and the nut 5 is disposed opposite to the screw hole.
As shown in fig. 7: the metal radiator a1 and the metal radiator b2 need to be tightly attached to each other, so that the heat of the metal radiator b2 can be conducted to the metal radiator a 1; meanwhile, the metal radiator a1 and the metal radiator b2 belong to two different electrical nodes and have the requirement of safe distance, so that isolation treatment is needed.
In a preferred embodiment, a preformed groove is formed in the metal radiator b2, the size of the connecting member 3 is matched with that of the preformed groove, and the connecting member 3 and the metal radiator b2 are positioned and installed through the preformed groove.
As shown in fig. 7: a prefabricated groove corresponding to the size of the connecting piece 3 is made on the metal radiator b2, so that the accurate positioning of the connecting piece 3 can be realized, and simultaneously, the position of the nut 5 in the connecting piece 3 can be aligned with the position of the screw hole on the metal radiator a1, so that the screw 7 can be locked.
