Abstract
The utility model discloses a flat-fuse seat assembly which is used for connecting a flat fuse. The flat-fuse seat assembly includes a long-strip insulation pedestal and two connecting bolts. The pedestal has an upper surface and a lower surface. Bolt heads of the two connecting bolts are pre-embedded and enclosed in the pedestal, and bolt bodies of the two connecting bolts penetrate the upper surface of the pedestal in a parallel manner. A long kidney-shaped groove with an upward opening is disposed between the two connecting bolts and is arranged in the middle of the upper surface of the pedestal. A fixing hole is disposed in the bottom surface of the long kidney-shaped groove. The flat-fuse seat assembly helps to improve insulation performance, and enhances an operation torsion force during the installation of a fuse, and the pedestal is not easy to fracture. The flat-fuse seat assembly allows certain installation dimension deviation between the flat-fuse seat and a fixed position. The material is saved, and the cost is reduced.
Description
Technical field
The utility model relates to a kind of dull and stereotyped fuse holder assembly.

Utility model content
The utility model provides a kind of dull and stereotyped fuse holder assembly, and it has overcome the deficiencies in the prior art described in background technology.
The technical scheme adopting that the utility model solves its technical problem is:
A kind of dull and stereotyped fuse holder assembly, for the flat fuse of attaching, it comprises a strip insulator foot and two attaching bolts, described base has upper surface and lower surface, the bolt head of described two attaching bolts is pre-buried is respectively enclosed in described base, and the parallel base upper surface that passes of the double-screw bolt of described two attaching bolts, offers an opening up long gain between two attaching bolts in the middle of the upper surface of described base, and the bottom surface of described long gain offers fixing hole.
Among one embodiment: described fixing hole comprises two, and be spaced along the length direction of this base, one is circular hole, and another is long lumbar hole, and the length direction of described long lumbar hole and the length direction of described base consistent.
Among one embodiment: the lower surface mid portion of described base is offered a groove, described fixing hole extends a fixed cover from the bottom surface correspondence of this groove, and the elongated end of described fixed cover is concordant with the lower surface of base.
Among one embodiment: described fixed cover is connected to the side of this groove by least one reinforcement.
Among one embodiment: described base is a rectangular shape.
Among one embodiment: the surrounding of described base lower surface is arranged with a square frame downwards.
Among one embodiment: described attaching bolt comprises M8 or M10 zinc electroplating with iridescent yellow chromate conversion coating iron bolt.
Among one embodiment: the material of described base comprises plastic material.
The technical program is compared with background technology, and its tool has the following advantages:
1, a dull and stereotyped fuse holder assembly, for the flat fuse of attaching, it comprises a strip insulator foot and two attaching bolts, and described base has upper surface and lower surface, and the bolt head of described two attaching bolts is pre-buried is respectively enclosed in described base; Make two bolt heads be unlikely to be exposed in air, improve the insulation property of this fuse holder assembly, by the pre-buried sealing mode of the bolt operation torsion when contributing to improve fuse and installing that is fixedly attached, be not easy to cause the fracture of base simultaneously.
2, described fixing hole comprises two, and is spaced along the length direction of this base, and one is circular hole, and another is long lumbar hole, and the length direction of described long lumbar hole and the length direction of described base consistent; This long lumbar hole allows to have certain installation deviation between this flat board fuse holder and fixed position.
3, in the middle of the upper surface of described base, offer an opening up long gain between two bolts, prevent from exceeding base upper surface for the head of screw of hold-down screw or the bolt head of bolt of fixed flat planar fuse holder, meanwhile, the material that prevents fixing hole place causes spalling during due to screw or bolted.
4, the lower surface mid portion of described base is offered a groove, described fixing hole extends a fixed cover from the bottom surface of this groove, the elongated end of described fixed cover is concordant with the lower surface of base, described fixed cover is connected to the side of this groove by least one reinforcement, by offering groove and connection strengthening rib, the in the situation that of influence technique effect not, save material, reduced cost.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 has illustrated the schematic perspective view of the dull and stereotyped fuse holder assembly with flat fuse described in the present embodiment.
Fig. 2 has illustrated one of schematic perspective view of the dull and stereotyped fuse holder assembly described in the present embodiment.
Fig. 3 illustrated the dull and stereotyped fuse holder assembly described in the present embodiment schematic perspective view two.
Embodiment
Please refer to Fig. 1 to Fig. 3, a kind of dull and stereotyped fuse holder assembly, for the flat fuse of attaching, it comprises a strip insulator foot 1 and two attaching bolts 2, described base 1 has upper surface 11 and lower surface 12, and the bolt head of described two attaching bolts 2 is pre-buried is respectively enclosed in described base 1, and the parallel base upper surface that passes of the double-screw bolt of described two attaching bolts 2, in the present embodiment, the material of described base 1 adopts plastic material.This two bolt heads plastic packaging is in this base 1, make it to be unlikely to cause causing unnecessary risk with external circuit conducting because being exposed in air, this measure has improved the insulation property of this fuse holder assembly, by the pre-buried sealing mode of the bolt operation torsion when contributing to improve fuse and installing that is fixedly attached, be not easy to cause the fracture of base simultaneously.
In the middle of the upper surface 11 of described base 1, offer an opening up long gain 13 between two attaching bolts 2, the bottom surface of described long gain 13 offers fixing hole.Described fixing hole comprises two, and is spaced along the length direction of this base 1, and one is circular hole 131, and another is long lumbar hole 132, and the length direction of described long lumbar hole 132 is consistent with the length direction of described base 1.This long lumbar hole 132 allows to have certain installation deviation between this flat board fuse holder and fixed position.
