Abstract
The invention relates to a metal bracket (10) for retaining fuses in the cover of a fused interrupter. Said bracket comprises a front section (12) and two wall sections (14) that extend perpendicularly from the front section. According to the invention, the bracket comprises a retaining flange (16) on the ends of the wall sections (14), said flange projecting laterally outwards from the adjacent wall sections.
Description
Technical field
The present invention relates to a kind of metal bracket, be used for the fuse of the lid of clamping fused interrupter, have a previous section and two wall parts that substantially perpendicularly extend from previous section.
Background technology
This metal bracket is known in the prior art.For the big closing force that in the lid that is controlled at fused interrupter, especially occurs when the NH-fuse of size 1,2,3 or 4a number, and use metal bracket.When opening such lid, must overcome frictional force until 50kN.For this reason, the metal bracket that starts described type of packing in the lid of fused interrupter is known.In the prior art, remain in the lid in order to make metal bracket, this metal bracket is pressed into and perhaps punching press or pass through bolted once more.In the prior art, the clamping of metal bracket is had problems, especially metal bracket often will be in many assembling campaigns and often be moved, and is held up to metallic support.
Summary of the invention
The objective of the invention is to, realize reliably and simplify clamping the metal bracket of the described type of beginning that is used for the clamping fuse.
Purpose of the present invention realizes by the metal bracket that starts described type, it is characterized in that, this metal bracket especially has gripping edge respectively on its end on two wall parts that begin from previous section, wherein gripping edge laterally outwards protrudes from affiliated wall part.Particularly, each gripping edge vertically outwards protrudes from affiliated wall part.
Can realize thus, i.e. fixing metal carriage on gripping edge, and at the lid of fused interrupter (being provided with a plurality of lattice that hold that are used for maintaining fuse usually therein) two clamping projectioies that are used for fixing the gripping edge that clamps metal bracket can be set so that this metal bracket placed in the middle all the time and maintenance is in place in assembling process.
Preferably, the length of gripping edge be affiliated wall part length 1/3rd to 2/3rds, and preferably, this length is half of length of affiliated wall part.This length can be seen clearly in the vertical view of metal bracket.
When wall part vertically from previous section stretch out and gripping edge vertically when affiliated wall part stretches out, gripping edge is parallel to previous section.This gripping edge can be previous section length 1/8th to 1/3rd, be preferably sixth to four/one of the length of previous section, be preferably especially previous section length 1/5th.
For metal bracket can clamp fuse, previous section has the slit of that begin from the top, the T shape head that is used for the clamping fuse, and the preferably upwards expansion of infundibulate ground of this slit just carries out the transition to the shape on inclined-plane from rectangular shape.Therefore, the slit can clamp the T shape head of fuse, and, can be inserted in the slit of metal bracket so be used for maintaining the T shape head of fuse at lid because metal bracket self is by gripping edge with clamp projection and be fixed in the lid of fused interrupter.
Fuse has two T shape heads usually, and in this case, each fuse that is used is by coming clamping by clamping protruding two metal brackets that clamp respectively.
Metal bracket also can be only on an assembly direction simply from above insert or be locked into the lid of fused interrupter.Corresponding fixation such as bolt or rivet is unwanted in corresponding structure design.The assembling that therefore, can need not to add is moved and assemble metal bracket in the lid of fused interrupter.
Therefore, metal bracket according to the present invention has been simplified the assembling of the lid that is used for fused interrupter by the structural design that clamps projection in integration of operation, saved the time thus in installation.
Description of drawings
Next, with reference to the accompanying drawings the preferred embodiments of the present invention are further specified, wherein:
Fig. 1 shows the perspective view according to metal bracket of the present invention,
Fig. 2 shows the sectional view of the lid of fused interrupter, and this lid has metal bracket fixing in lid and the fuse that remains on the metal bracket, and
Fig. 3 shows the perspective view of two accommodation sections of the lid of fused interrupter, and wherein, the NH-fuse that keeps by metal bracket according to the present invention is in one to be held in the lattice.
Embodiment
Fig. 2 shows the cross section of the top observation of the lid that is used for fused interrupter.This lid have three be used for the clamping fuse hold lattice 24.Each holds lattice and has two and clamp projection 26, and it is made of plastics and slight elasticity arranged, and this holds lattice have the gripping edge that is used to hold metal bracket 10 between himself and kicker baffle 28 gap.The right side of Fig. 2 shows clamped protruding 26 and the metal bracket 10 of kicker baffle 28 clampings.Insert the T shape head of fuse 32 in the slit of metal bracket 10, this T shape head is fixed on the holding in the lattice 24 of lid of fused interrupter.T shape head is formed by rectangular basically zone, cross section, has a neck 34 after this zone, and its width is slightly little, to such an extent as to fuse 32 can be pushed in the slit and prevents moving of T shape 32 by neck.
Fig. 3 shows the lid that is used for fused interrupter, and it has two and holds lattice 24, and wherein, fuse is fixed on the lattice that hold on the right.This perspective view illustrates, and is fixed on as metal bracket 10 (each holds lattice 24, and promptly a fuse 32 has two metal brackets) to clamp on the projection.
From Fig. 3 also as can be seen, metal bracket can insert from the top, and will clamp projection by lighter pressure and press to both sides, and should clamp protruding resilience force, is therefore fixed by this clamping projection.In the opening and closing lid, securing metal bracket also stands bigger closing force.
