[0002] A fuse is an electrical appliance that disconnects the circuit by melting the fuse when the current exceeds the specified value. It can be used for isolation protection between the power supply and the load. When a short circuit or overload occurs in the circuit of the electrical equipment, the fuse can automatically cut off the circuit to avoid damage to the electrical equipment and prevent electrical accidents.

[0003] The existing fuse mainly consists of three parts: a fuse body, a fuse carrier and a base. The fuse body is installed in the cavity of the fuse carrier. The fuse carrier is set in an open or closed manner on the base. The fuse carrier has a accommodating cavity suitable for installing the fuse body. An indicator light for indicating whether the fuse is on or off is set on the fuse carrier. Specifically, a lamp hole is opened on the top of the fuse carrier, and the indicator light is squeezed and inserted into the lamp hole. The two pins of the indicator light are connected to the fuse body below through two contact pieces. When current flows into the fuse body, the indicator light lights up to indicate that the fuse is in the on state. However, the installation method of the indicator light of this fuse still has the following problems in practice: Since the indicator light and the lamp hole are squeezed and clamped by size matching, during use, this indicator light is easy to loosen when touched and squeezed by external force, and slides back and sinks into the lamp hole, and the installation stability is poor, which affects the indication effect of the indicator light. Utility Model Content

[0008] In the above-mentioned melt carrier device, the limit stopper comprises two second limit protrusions which are matched and inserted into the two connecting grooves. After the two second limit protrusions are installed, the two conductive spring sheets are squeezed and clamped in the two slot structures.

[0009] In the above-mentioned melt carrier device, the limit stopper is in a plate-shaped structure and blocks the opening of the installation slot, so that the limit stopper remains flush with the side surface of one side of the melt carrier after installation.

[0027] Example

[0028] The utility model provides Figure 1-4A fuse-carrying device is shown, comprising a fuse-carrying component 1, an indicator light 4 arranged on the fuse-carrying component 1, and a fuse-carrying cavity 2 for installing a melt, a mounting groove 3 is provided on one side of the fuse-carrying component 1, a lamp hole 11 connected to the mounting groove 3 is provided on the top of the fuse-carrying component 1, the indicator light 4 is squeezed into the lamp hole 11 from the mounting groove 3, the top of the indicator light 4 extends out of the lamp hole 11, and the bottom of the indicator light 4 is accommodated in the mounting groove 3, and further comprises a limit stopper 5 matched and filled in the mounting groove 3, the limit stopper 5 has a first limit protrusion 51 extending toward the inner side of the mounting groove 3 and limitingly abutting against the bottom of the indicator light 4, and when the limit stopper 5 is installed in the mounting groove 3, the first limit protrusion 51 is used to block the indicator light 4 from downwardly exiting the lamp hole 11.

[0029] The above implementation mode is the core technical solution of this embodiment. According to the indicator light 4, it is installed into the position of the lamp hole 11 from the mounting groove 3. A limit stopper 5 with a matching size and shape is installed in the mounting groove 3. The limit stopper 5 has a first limit protrusion 51 that is limited and abutted against the bottom of the indicator light 4. The advantage of such a design is that the limit stopper 5 just covers the opening position of the mounting groove 3 after being installed in place to avoid exposing the lamp foot part of the indicator light 4, thereby protecting the indicator light 4 in the mounting groove 3 and having good installation aesthetics. At the same time, the first limit protrusion 51 is used to limit the installation of the indicator light 4, so that the indicator light 4 is limited and clamped in the lamp hole 11 under the squeezing action of the first limit protrusion 51, thereby preventing the indicator light 4 from sliding back and sinking from the lamp hole 11 to the mounting groove 3 due to vibration or external force, so as to ensure the stability and tightness of the installation of the indicator light 4.

[0030] Further preferably, Figure 1-2 As shown, the mounting groove 3 is connected to the upper side of the melt carrier cavity 2, the melt carrier 1 includes two connecting grooves 6 connected between the mounting groove 3 and the melt carrier cavity 2, the indicator light 4 has two conductive springs 41 that penetrate into the melt carrier cavity 2 through the two connecting grooves 6, and the two conductive springs 41 are in contact with both ends of the melt, wherein the two connecting grooves 6 are arranged through the side wall of the mounting groove 3 connected to the melt carrier cavity 2, and two slot structures 7 for installing the two conductive springs 41 are respectively arranged in the two connecting grooves 6, the opening direction of the connecting groove 6 and the slot structure 7 is consistent with the opening direction of the mounting groove 3, with this structural arrangement, the indicator light body is installed in the lamp hole, and its two conductive springs are inserted in the two slot structures, and penetrate into the melt carrier cavity to contact the melt, and the conductive springs are positioned and connected in the connecting groove through the slot structure.

[0031] In order to prevent the conductive spring sheet 41 from being separated from the slot structure 7, Figure 1-3As shown, the limit stopper 5 is a plate-shaped structure and blocks the opening of the installation slot 3. After installation, the limit stopper 5 remains flush with the side surface of the fuse carrier 1, thereby realizing a closed installation of the indicator light 4 located in the installation slot 3, with good overall protection and improved aesthetics of the fuse carrier device. Specifically, the limit stopper 5 includes two second limit protrusions 52 that are matched and inserted into the two connecting slots 6, so that the opening positions of the installation slot 3 and the slot structure 7 are blocked by the second limit protrusions 52. After the two second limit protrusions 52 are installed, the two conductive springs 41 are squeezed and clamped in the two slot structures 7, so that the two conductive springs 41 can be prevented from loosening or detaching in the slot structure 7, thereby playing a role in limiting the installation of the two conductive springs, with reliable matching and good installation stability.

[0032] As a specific structural setting, such as Figure 4 As shown, the first limiting protrusion 51 is a limiting protrusion formed on one side of the limiting stopper 5, one end of the limiting protrusion is vertically connected to the side of the limiting stopper 5, and the other end thereof extends to abut against the bottom of the indicator light 4. When the first limiting protrusion 51 is inserted into the mounting groove 3, it just abuts against the bottom of the indicator light 4 and pushes the indicator light upward to be squeezed and stuck in the lamp hole. Since the bottom diameter of the indicator light 4 is larger than the diameter of the lamp hole 11, the clamping and limiting fit between the indicator light and the lamp hole is achieved, thereby improving the installation strength of the indicator light and avoiding the slipping phenomenon. It is further preferably arranged that the two second limiting protrusions 52 are respectively two limiting bosses formed in an L shape on the bottom edge of the limiting stopper 5, and the first limiting protrusion 51 is connected to one of the second limiting protrusions 52 to form a T-shaped structure. With this structural arrangement, when the limiting stopper 5 is installed in the mounting groove 3, the first limiting protrusion 51 and the two second protrusions play a three-point limiting installation effect on the entire indicator light 4, greatly improving the stability of the installation of the indicator light 4.

[0033] In this embodiment, if Figure 3-4 As shown, a limiting edge strip 53 is provided on the top edge of the limiting stopper 5, and a limiting edge groove 8 which forms a limiting cooperation with the limiting edge strip 53 is correspondingly provided on the other side wall of the installation groove 3. In summary, two connecting grooves 6 are provided on one side wall of the installation groove 3, and a limiting edge groove 8 is provided on the other side wall thereof. In addition, two second limiting convex edges inserted into the two connecting grooves 6 are provided on the bottom edge of the limiting stopper 5, and a limiting edge strip 53 inserted into the limiting edge groove 8 is provided at the top edge position thereof. The advantage of such an installation design is that when the limiting stopper 5 is installed in the installation groove 3, it can be ensured that both sides thereof have a force support effect, avoiding the situation where one side sinks and the other side rises, thereby ensuring the flatness and stability of the installation of the limiting stopper.

[0034] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
