PTC heating elements have the advantages of low thermal resistance and high heat exchange efficiency, making them an automatic temperature-controlled and energy-saving electric heater.

[0003] For example, the prior art publication number CN217486671U describes a PTC heater that is easy to connect. This utility model has a connector on the outside of the PTC heater body, and a connecting groove is opened on one side of the connector. The connector body is connected to the connector head through the connecting end of the connector body, so that multiple PTC heater bodies can be connected. This avoids the traditional screw connection, which is prone to screw rusting and loosening over time.

[0004] However, the existing technology described above still has the following problems in use: When connecting the main bodies of traditional heaters, the main bodies are usually connected first using a connecting structure, and then the wires of each heater body are connected, which is very time-consuming and affects the connection speed. Based on this, the present invention provides a PTC heater that is easy to connect. Utility Model Content

[0009] In a preferred embodiment, a rubber protrusion is fixedly provided at the bottom of the protective cover, and a corresponding slot is provided at the top of the heater body. The rubber protrusion engages with the slot, and the friction between the protective cover and the heater body is increased by the cooperation of the rubber protrusion and the slot, thereby improving the stability of the protective cover.

[0010] In a preferred embodiment, each plug has two first storage holes symmetrically distributed vertically, and each first storage hole is provided with a first fastening bolt. The plug is detachably fixed to the connecting block by the first fastening bolt, which makes it convenient for staff to remove the plug from the rectangular groove for inspection and replacement.

[0011] In a preferred embodiment, each socket has two symmetrically distributed second storage holes on its outer wall. Each second storage hole is equipped with a second fastening bolt. The socket is detachably fixed to the heater body by the second fastening bolt, which facilitates the disassembly of the socket for inspection and replacement.

[0012] In a preferred embodiment, rectangular mounting holes are provided at all four corners of the bottom of the heater body, and multiple rectangular mounting holes are provided to improve the stability of the heater body during installation and use.

[0013] The technical effects and advantages of this utility model are as follows:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Refer to the instruction manual appendix Figures 1-6This utility model provides a PTC heater that is easy to connect, including a heater body 1. A wire 9 is connected to the front end of the heater body 1 for power supply. Rectangular mounting holes 19 are provided at the four corners of the bottom of the heater body 1. Multiple rectangular mounting holes 19 are provided to improve the stability of the heater body 1 during installation and use.

[0025] Two symmetrically distributed connecting blocks 2 are fixed on one side of the heater body 1. Two connecting grooves 3 corresponding to the connecting blocks 2 are opened on the other side of the heater body 1. First bolts 4 are threadedly connected to both the front and rear sides of the heater body 1. Threaded holes 5 corresponding to the first bolts 4 are opened on the opposite side of the two connecting blocks 2. A rectangular groove 6 is opened at the center of the outer wall of each connecting block 2. A plug 7 is provided inside the rectangular groove 6. A socket 8 corresponding to the plug 7 is provided inside each connecting groove 3. When the two heater bodies 1 are connected, the plug 7 is automatically inserted into the socket 8 to complete the series connection.

[0026] In practical use, when multiple heater bodies 1 need to be connected, the operator inserts the two connecting blocks 2 on the side of one heater body 1 into the two connecting slots 3 on the side of another heater body 1, and then pushes the two heater bodies 1 closer together. After the connecting blocks 2 are tightly fitted with the inner wall of the connecting slots 3, the operator tightens the multiple first bolts 4 to firmly fix the connecting blocks 2 and the heater body 1 together. At this time, the two pins on the plug 7 are also inserted into the socket 8, realizing the connection between the plug 7 and the socket 8. The operator does not need to connect the wires 9 of the two heater bodies 1. The two heater bodies 1 can be connected in series. When adding more heater bodies 1, the above installation steps can be followed. The structure is simple and can realize series power supply at the same time as connection, thereby shortening the wiring time and improving the connection speed.

[0027] In this embodiment, as Figure 4 and Figure 5 As shown, each plug 7 has two symmetrically distributed first storage holes 15, and each first storage hole 15 has a first fastening bolt 16 inside. The plug 7 is detachably fixed to the connecting block 2 by the first fastening bolt 16. Each socket 8 has two symmetrically distributed second storage holes 17 on its outer wall, and each second storage hole 17 has a second fastening bolt 18 inside. The socket 8 is detachably fixed to the heater body 1 by the second fastening bolt 18.

[0028] The plug 7 is installed in the rectangular groove 6 using the first fastening bolt 16, and the socket 8 is installed in the connecting groove 3 using the second fastening bolt 18. The plug 7 and the socket 8 are respectively provided with the first storage hole 15 and the second storage hole 17 to prevent the first fastening bolt 16 and the second fastening bolt 18 from protruding outward and affecting the connection between the plug 7 and the socket 8. By loosening the first fastening bolt 16 and the second fastening bolt 18, the plug 7 and the socket 8 can be removed for inspection and replacement.

[0029] Refer to the instruction manual appendix Figures 1-3 and Figure 6 The outer side of the wire 9 is fitted with a protective cover 10, which is movably hinged to the front end of the heater body 1. The front end of the protective cover 10 has a wire management hole 11, and a lever 12 is fixedly provided at the front end of the protective cover 10. The lever 12 is located above the wire management hole 11.

[0030] The bottom of the protective cover 10 is fixed with a rubber protrusion 13, and the top of the heater body 1 is provided with a slot 14 corresponding to the rubber protrusion 13. The rubber protrusion 13 is engaged with the slot 14. The cooperation between the rubber protrusion and the slot can increase the friction between the protective cover and the heater body, thereby improving the stability of the protective cover.

[0031] The protective cover 10 is installed to wrap the wire 9 to prevent the wire 9 from becoming loose and damaged, thereby improving the service life of the wire 9 and thus improving the stability and safety of the heater body 1.

[0032] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
