Description

Technical Field

[0001] This utility model relates to the field of thermal fuse application technology, and in particular to a thermal fuse with a ceramic base assembly. Background Technology

[0002] Thermal fuses are important overheat protection components, mainly used to quickly cut off the circuit when electrical equipment or circuits overheat abnormally, preventing equipment damage, fires and other dangerous accidents.

[0003] Existing thermal fuses are generally directly connected inside electrical equipment during use. However, during installation and disassembly, the equipment needs to be removed and then re-welded to fix it according to the leads. This process is cumbersome and cannot achieve quick assembly and disassembly. In addition, the thermal fuse has a high temperature after failure, making it inconvenient for workers to remove it directly, which reduces work efficiency. Therefore, this utility model proposes a thermal fuse with a ceramic base assembly. Utility Model Content

A protective block is fixedly connected to the top of the ceramic base near one end. Two inserts symmetrically extend from the top of the protective block and near both sides through the bottom of the ceramic base to limit and fix the installation position of the inserts and the thermosetting fuse body.

[0006] The present invention is further configured such that: a positioning hole is provided at the top of the ceramic base away from the protective block, and a settling groove is provided at the top of the positioning hole.

[0007] The above technical solution facilitates the use of bolts to further reinforce and stabilize the entire component during installation and fixing.

[0008] The present invention is further configured such that: the protective block is columnar and has symmetrical welding slots near both sides, and the welding joints of the heat-fused fuse body and the two inserts are respectively located inside the two welding slots.

[0009] The above technical solution uses a protective block to protect the connection between the fuse body and the insert, preventing damage to the connection during operation.

[0011] The above technical solution facilitates the use of a limiting groove to limit and fix the position of the insert, while the use of a welding movable groove facilitates the welding process of the thermofused fuse body.

[0012] The present invention is further configured such that: a partition strip is fixedly connected to the bottom of the ceramic base, and the partition strip is Y-shaped in general.

[0013] The above technical solution facilitates the use of spacers to separate the limiting folded edge A of the insert when installing the ceramic base, thereby improving its stability after installation and increasing the contact area with the external environment.

[0014] The present invention is further configured such that: a pressing protrusion is pressed into the middle position of the insert, and the outer arc wall of the pressing protrusion is attached to the inner wall of the limiting groove; both sides of the insert located in the limiting groove are provided with matching folded edges, and the bending direction of the matching folded edges is opposite to the protrusion direction of the pressing protrusion, and they are attached to the inner wall of the limiting groove.

[0015] The above technical solution facilitates the stable fit of the insert piece when it is installed inside the limiting groove using the extrusion protrusion, and further reinforcement can be achieved by using the matching folded edge, thereby improving the firmness of the insert piece in the limiting groove.

[0016] The present invention is further configured such that: the two side walls of the insert are respectively provided with limiting flange A and limiting flange B at the bottom and top positions near the mating flange, the limiting flange A is limited to the bottom of the ceramic base, and the limiting flange B is internally attached to the inner bottom of the welding movable groove.

[0017] The above technical solution facilitates the bending of limiting edge A and limiting edge B when the insert is installed inside the limiting groove, so that they fit against the two sides of the limiting groove respectively, thereby limiting and fixing the position of the entire insert.

[0018] The present invention is further configured such that each of the two inserts has an opening near its end.

[0019] The above technical solution facilitates connection and fixation during plug-in use, and can also be reinforced by welding.

[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0024] like Figures 1-4As shown, a thermocouple with a ceramic base assembly includes a thermocouple body 3. Two pins of the thermocouple body 3 are welded with inserts 2 for flexible assembly and disassembly. A ceramic base 1 is inserted through the two inserts 2 to fix their positions. A positioning hole 11 is provided at the top of the ceramic base 1, away from the protective block 12, and a settling groove is provided at the top of the positioning hole 11 to facilitate further reinforcement and stability using bolts during assembly. Limiting grooves 14 are symmetrically provided at the bottom of the ceramic base 1 near both sides. The tops of the two limiting grooves 14 are respectively connected to the two welding movable grooves 13, and the two inserts 2 are respectively attached to the inside of the two limiting grooves 14, which makes it convenient to use the limiting grooves 14 to limit and fix the position of the inserts 2. The welding movable grooves 13 facilitate the welding of the thermosetting body 3. The bottom of the ceramic base 1 is fixedly connected to a spacer 15, and the spacer 15 is Y-shaped. When the ceramic base 1 is inserted and installed, the spacer 15 can be used to separate the limiting folded edge A23 of the insert 2, improve its stability after installation, and increase the contact area with the external environment.

[0025] like Figures 2-4As shown, a protective block 12 is fixedly connected to one end of the top of the ceramic base 1. The protective block 12 is columnar and has symmetrical welding grooves 13 near both sides. The welding joints of the thermosetting fuse body 3 and the two inserts 2 are located inside the two welding grooves 13. The protective block 12 protects the connection between the thermosetting fuse body 3 and the inserts 2, preventing damage to the connection during operation. The two inserts 2 extend symmetrically from the top of the protective block 12 and near both sides through the bottom of the ceramic base 1 to limit and fix the installation position of the inserts 2 and the thermosetting fuse body 3. An extrusion protrusion 21 is extruded at the middle of the insert 2, and the outer arc wall of the extrusion protrusion 21 fits against the inner wall of the limiting groove 14. Both sides of the insert 2 within the limiting groove 14 are provided with mating flanges 22, and the bending direction of the mating flanges 22 is opposite to the protruding direction of the extrusion protrusion 21, while fitting against the limiting groove 14. The inner wall of the 4 is designed to allow the insert 2 to be stably fitted using the extrusion protrusion 21 when it is installed inside the limiting groove 14. It also allows for further reinforcement using the mating fold 22, improving the stability of the insert 2 within the limiting groove 14. Limiting folds A23 and B24 are respectively provided on the two side walls of the insert 2 near the bottom and top positions of the mating fold 22. Limiting fold A23 is fitted to the bottom of the ceramic base 1, and limiting fold B24 is fitted to the inner bottom of the welding movable groove 13. This allows the limiting folds A23 and B24 to be bent and fitted to the two sides of the limiting groove 14 when the insert 2 is installed inside the limiting groove 14, thus fixing the position of the insert 2. Openings 25 are provided near the ends of both inserts 2 for easy connection and fixation during insertion, and they can also be welded for reinforcement.

[0026] In use, the two inserts 2 are inserted into the limiting groove 14 respectively, and the limiting flanges A23 and B24 are used to bend them so that they fit against the two sides of the limiting groove 14 respectively, thereby limiting and fixing the position of the entire insert 2. Finally, the two leads of the thermosetting fuse body 3 are welded to the two inserts 2.
