Description

Fastenerless fuse card firmware

The present invention relates to a card structure, and more particularly to a card fastener for a cardless fuseless switch.

A fuseless switch is an overcurrent protection device. In short, it is usually used as a power switch for an indoor circuit. When the current flowing through the non-fuse switch is excessive, the switch will automatically jump to form an open circuit. In order to avoid overload currents from damaging the electrical appliances connected to the power supply or their internal components.

Referring to FIG. 8 , in general, the non-fuse open relationship is installed in the power transformer box, and is installed in the housing 91 of the fuseless switch with two positioning slots 92 formed thereon. The two positioning slots 92 are respectively formed on the top surface and the bottom surface of the housing. The user can insert two ends of the two fixed iron pieces 93 into the two positioning slots 92 through the two Z-shaped fixed iron pieces 93. One end abuts against the wall surface of the transformer box and is fixed by screwing, so that the two fixed iron pieces 93 abut against the non-fuse switch and are locked on the wall surface of the transformer box.

However, the prior art positioning slot 92 has the following disadvantages.

First, since the slot of the positioning slot 92 designed by the prior art is too large, when the user inserts the fixed iron piece 93, the fixed iron piece 93 is easily shaken relative to the positioning groove 92, so that the user cannot perform the construction stably, so the device is installed. It is very inconvenient to set up; Secondly, as the first point, if the fuseless switch is to be firmly locked, the best way is to manually support the fuseless switch housing 91, and the other person to carry the upper and lower fixed iron pieces 93. Simultaneous locking, but this will cause a burden on labor costs; Thirdly, since the housing 91 and the fixed iron piece 93 have special specifications, if the size of the positioning groove 92 is re-opened, the cost is too high, and even if the size of the positioning groove 92 is reduced, the positioning groove 92 is very Small, making it easier to produce machining errors during processing, and it is very likely that the fixed iron piece 93 cannot be accurately placed in the positioning groove 92 without shaking; on the other hand, if the iron piece 93 is to be fixed Thickness thickening, although it is easier to overcome in processing, it will require more materials, so it is also disadvantageous in terms of processing cost control. In other words, the prior art fuseless switch cannot be low cost. In an efficient manner, the problem of the sway of the fixed iron piece 93 during assembly and poor assembly is solved.

In view of the shortcomings and deficiencies of the prior art, the present invention provides a fuseless fuse-free card fastener, which is relatively easy to insert a fixed iron piece into a fuseless switch housing by filling a space inside the positioning groove. Shaking.

For the purpose of the above creation, the technical means adopted by the present invention is a fuseless fuse card fastener for fixing a fixed iron piece in a positioning groove on a fuseless switch housing, the positioning The groove has a length direction and a width direction which are perpendicular to each other on a horizontal plane, wherein the fastener is an elastic rectangular plate body received in the positioning groove, and the thickness of the fastener along the width direction and the The total thickness of the fixed iron piece along the width direction is greater than the width of the positioning groove along the width direction. Therefore, when the fixed iron piece is inserted into the positioning groove, the fixed iron piece is tightly sandwiched between the fastener and the positioning groove. Between the inner walls.

The advantage of this creation is that by installing and filling the creation into the space in the positioning groove of the fuseless switch housing, when the user puts a fixed iron piece into the positioning groove, the fixed iron piece is subject to the creation. And the squeezing and clamping between the inner wall surfaces of the positioning groove, so that it is less likely to sway relative to the fuseless switch housing, and because the creation is low in cost, the cost is not caused to the user. In other words, the present invention solves the problem that the fuseless switch housing is not easily locked due to the sloshing of the iron piece when the fixed iron piece is mounted in a low cost and simple manner.

Further, the fastener of the aforementioned fuseless switch, wherein the length of the fastener along the length direction is less than or equal to the length of the positioning groove along the length direction.

Further, in the above-mentioned fastenerless switch, the fastener is further provided with an adhesive on one side of the width direction, and the fastener is fixed to an inner wall surface of the positioning groove through the adhesive.

Further, the fastener of the aforementioned fuseless switch, wherein the fastener further comprises a grip portion formed on the other side opposite to the adhesive.

Further, in the above-mentioned fastener without a fuse switch, the grip portion is an extension of one end portion of the fastener, and is bent toward the side opposite to the side where the adhesive is provided.

Further, the fastener of the fuseless switch, wherein the length of the fastener along the length direction is greater than the length of the positioning slot along the length direction, so that the two ends of the fastener along the length direction are close to the The inner wall surface of the groove is positioned, and the fastener is bent in the positioning groove.

Further, the fastener of the aforementioned fuseless switch, wherein the fastener is made of foam.

Further, the fastener of the aforementioned fuseless switch, wherein the fastener is made of rubber.
