Description

Technical Field

[0001] This application relates to the field of fuses, and more particularly to a composite strip for preparing a melt and a melt structure. Background Technology

[0002] A fuse is a current protection device that works by melting a fusible element due to the heat generated when the current exceeds a specified value for a certain period of time, thus breaking the circuit. The fuse contains a fusible element; when a short circuit occurs, the fusible element melts under high temperature, thereby protecting the electrical appliance.

[0003] Existing melts are usually made of copper and silver composites. However, due to the high price of silver, using more silver would increase costs. Therefore, it is necessary to reduce the cost of the melt without affecting the melting effect. Utility Model Content

[0004] In order to reduce the cost of melt, this application provides a composite strip and melt structure for preparing melt.

[0005] This application provides a composite strip and melt structure for preparing melts, employing the following technical solution:

[0006] A composite strip for preparing a melt includes a copper strip and a silver strip. The copper strip has two sets of first mounting grooves, which are located on both sides of the copper strip. Each set has a plurality of first mounting grooves, which are distributed along the width direction of the copper strip. The length of the first mounting groove is parallel to the length direction of the copper strip, and the depth of the first mounting groove is less than the thickness of the copper strip. A plurality of silver strips are provided, and each silver strip is respectively engaged in one of the plurality of first mounting grooves.

[0007] By adopting the above technical solution, the silver strip is divided into two groups, which are respectively set on both sides of the copper strip. On the one hand, it will not affect the conductivity and melting effect of the composite strip after it is made into a melt, and on the other hand, it saves silver material, thereby saving costs.

[0008] Optionally, the two sets of the first mounting grooves are arranged symmetrically, and the depth of the first mounting groove is less than half the thickness of the copper strip.

[0009] Optionally, the width of the first mounting groove gradually decreases from the bottom of the groove towards the opening.

[0010] By adopting the above technical solution, the width of the first mounting groove gradually decreases from the bottom of the groove to the opening, thereby improving the installation strength and stability of the silver strip and copper strip.

[0011] Optionally, the two sets of the first mounting slots are staggered and alternately arranged.

[0012] By adopting the above technical solution, the two sets of first mounting slots are staggered and alternately arranged, which allows the depth of the first mounting slots to be opened to a greater extent, thereby facilitating the opening of the first mounting slots on the copper strip.

[0013] Optionally, the bottom wall of the first mounting groove is provided with silver wires, the length direction of the silver wires is parallel to the length direction of the first mounting groove, and a plurality of silver wires are provided, which are distributed along the width direction of the first mounting groove.

[0014] By adopting the above technical solution, silver wires are provided. When the silver strip is installed inside the copper strip, if the silver strip is thick, the silver wires can adapt to deformation, so that the surface of the silver strip is flush with the surface of the copper strip.

[0015] Optionally, a second mounting groove is provided on the bottom wall of the first mounting groove for mounting the silver wire.

[0016] By adopting the above technical solution, a second mounting groove is provided on the bottom wall of the first mounting groove for the installation of silver wire, thereby improving the stability of the silver wire installation.

[0017] A melt structure comprising the aforementioned composite strip, wherein the composite strip is folded along its width direction such that the composite strip is in a wavy folded shape.

[0018] By adopting the above technical solution, the fusible element of the fuse is made from the above composite strip, thereby achieving the goal of saving costs.

[0019] Optionally, the silver strip has several through holes, which are distributed along the length of the silver strip and extend to the other side of the copper strip.

[0020] By adopting the above technical solution, the conductor area can be reduced by punching holes in the composite strip, thereby increasing the current density and making the melt easier to melt in the event of a short circuit.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. Divide the silver strip into two groups, and place the two groups of silver strips on both sides of the copper strip. On the one hand, this will not affect the conductivity of the composite strip after it is made into a melt, and on the other hand, it saves silver material, thereby saving costs.

[0023] 2. It is equipped with silver wires. When the silver strip is installed inside the copper strip, if the silver strip is thick, the silver wires can adapt to the deformation, so that the surface of the silver strip is flush with the surface of the copper strip. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0032] Example 1:

[0033] This application discloses a composite strip for preparing melts. (Refer to...) Figure 1 and Figure 2 The system includes a copper strip 1 and a silver strip 2. The copper strip 1 has two sets of first mounting grooves 11, located on opposite sides of the copper strip 1. Each set contains several first mounting grooves 11, spaced apart along the width of the copper strip 1, with the length of each groove parallel to the length of the copper strip 1. Several silver strips 2 are provided, each secured within one of the first mounting grooves 11.

[0034] Reference Figure 1 and Figure 2 In this embodiment, the two sets of first mounting grooves 11 are symmetrically arranged, and the depth of the first mounting groove 11 is less than half the thickness of the copper strip 1.

[0035] Reference Figure 1 and Figure 2 In this embodiment, the cross-section of the first mounting groove 11 is rectangular. In other embodiments, the cross-section of the first mounting groove 11 may be other shapes.

[0036] Reference Figure 3 This embodiment also discloses a melt structure, including a composite strip, which is folded along the width direction to make the composite strip wavy.

[0037] Reference Figure 3The silver strip 2 has several through holes 21, which are distributed along the length of the silver strip 2 and extend to the other side of the copper strip 1. This reduces the conductor area and increases the current density, making it easier for the melt to melt in the event of a short circuit.

[0038] The implementation principle of Embodiment 1 of this application is as follows: the silver strip 2 is divided into two groups, and the two groups of silver strip 2 are respectively set on both sides of the copper strip 1. On the one hand, it will not affect the conductivity and melting effect of the composite strip after it is made into a melt, and on the other hand, it saves silver material, thereby saving costs. Example 2:

[0039] The difference between Example 2 and Example 1 is that, referring to Figure 4 The width of the first mounting groove 11 gradually increases from the bottom of the groove towards the opening.

[0040] The implementation principle of Example 2 is to facilitate the installation of silver strip 2 and copper strip 1.

[0041] Example 3:

[0042] The difference between Example 3 and Example 1 is that, referring to Figure 5 The width of the first mounting groove 11 gradually decreases from the bottom of the groove to the opening of the groove, so that the cross-section of the first mounting groove 11 is dovetail-shaped.

[0043] The implementation principle of Example 3 is as follows: the width of the first mounting groove 11 gradually decreases from the bottom of the groove to the opening of the groove, thereby improving the installation strength and installation stability of the silver strip 2 and the copper strip 1.

[0044] Example 4;

[0045] The difference between Example 4 and Example 2 is that, referring to Figure 6 The two sets of first mounting grooves 11 are staggered and alternately arranged, which allows the depth of the first mounting grooves 11 to be opened to a greater extent, thereby facilitating the opening of the first mounting grooves 11 on the copper strip 1.

[0046] Reference Figure 6 The bottom wall of the first mounting groove 11 is provided with a second mounting groove 12. The length direction of the second mounting groove 12 is parallel to the length direction of the first mounting groove 11. There are several second mounting grooves 12. The several second mounting grooves 12 are spaced apart along the width direction of the first mounting groove 11. There are several silver wires 3 respectively stuck in the several first mounting grooves 11.

[0047] The implementation principle of Example 4 is as follows: a silver wire 3 is provided. When the silver strip 2 is installed inside the copper strip 1, if the thickness of the silver strip 2 is large, the silver wire 3 can adapt to the deformation so that the surface of the silver strip 2 is flush with the surface of the copper strip 1.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
