Abstract
The utility model provides a fuse-link base structure, the base adopts PBT + GF 30% material an organic whole injection moulding the both ends can be dismantled fixedly and be provided with the clamping device of fixed fuse-link above the base. The base is simple in structure and is integrally formed through injection molding, so that the weight of the base is reduced.
Description
Technical Field
The invention belongs to the field of circuit protection, and particularly relates to a base structure of a fuse link for circuit protection.
Background
Currently, the NH product base uses DMC material, which has high viscosity and poor fluidity, and the forming method mainly adopts compression molding or machining. For a base with a larger size, due to the processing technology problem of DMC materials, the general design of the base structure is simpler, and the processing amount is reduced as much as possible, so that the base structure is simple, the base material consumption is more, and the weight is relatively heavier.
Disclosure of Invention
The invention aims to solve the technical problem of providing a fuse link base which is formed by integrally forming a plurality of grid-shaped reinforcing ribs at the bottom of the base through injection molding, so that the weight of the base is reduced.
In order to achieve the purpose, the technical scheme provided by the invention is a fuse-link base structure, the base is integrally formed by injection molding by adopting PBT + GF 30%, and clamping devices for fixing the fuse-link are detachably and fixedly arranged at two ends of the upper surface of the base.
Preferably, a plurality of reinforcing ribs are integrally formed at the bottom of the base.
Preferably, the reinforcing ribs are arranged at the bottom of the base in a grid shape.
Preferably, the clamping device comprises an electrically conductive connecting plate which is fastened to the base and on which an electrically conductive clip is arranged, into which a contact blade of the fuse link can be inserted.
Preferably, the clip comprises two conductive metal sheets which are oppositely arranged, and the conductive metal sheets are integrally and conductively connected with the connecting plate.
Preferably, a clamping ring is fixedly arranged on the connecting plate, and two open ends of the clamping ring are fixedly connected to the conductive metal sheet respectively.
Preferably, a groove is formed between the two conductive metal sheets, and a fixing block is arranged at the position, close to the bottom, of the groove.
Preferably, the base is shaped like a boat.
The fuse-link base structure of the invention is integrally formed by injection molding, and a plurality of latticed reinforcing ribs are formed at the bottom, thereby reducing the weight of the base while ensuring the structural strength.
Drawings
FIG. 1 is a side perspective view of a base structure.
Fig. 2 is a bottom perspective view of the base structure.
Detailed Description
With respect to the above technical solutions, preferred embodiments are described in detail with reference to the drawings.
The fuse-link base 1, refer to fig. 1 and fig. 2, is made of PBT + GF 30% and is formed by injection molding. The base 1, the appearance is the ship type structure, has several strengthening ribs 10 at the integrative injection moulding in base bottom, and the strengthening rib is the setting of latticed structure and base bottom. The material consumption of the base is reduced through the reinforcing rib structure with the grid-shaped structure, and the weight of the base is reduced.
Two ends of the upper surface of the base 1 are formed with accommodating grooves 11, and clamping devices are arranged in the accommodating grooves 11. The clamping device comprises an electrically conductive connecting plate 12 which is arranged in the receiving recess 11 by means of bolting. One end of the connecting plate 12 extends out of the base and can be connected with a user circuit through the bolt structure 13, the other end of the connecting plate is bent upwards to form a clamp 14, the clamp 14 comprises two conductive metal sheets, the conductive metal sheets are integrally connected with the connecting plate, a groove is formed between the two conductive metal sheets, and a fixing block 15 is fixedly arranged at the position, close to the bottom, of the groove. A clamping ring 16 is provided on the connecting plate 12, and both ends of the opening of the clamping ring are fixed to the back surfaces of the conductive metal sheets of the clips 14, respectively. The upper opening of the clamp 14 is in a trumpet-shaped structure, so that the contact knife of the fuse link can be conveniently inserted. The fuse link contact cutter is supported by a fixing block 15.
Notches are respectively formed in two sides of the upper surface of the base between the two clamping devices, through holes 17 penetrating through the base are formed in the notches, and after a contact knife of the fuse-link is inserted into the clamping devices, a shell part of the fuse-link is fixed on the upper surface of the base through bolts.
