DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The support base is used to install the PTC heater in heating equipment such as air conditioners and water heaters, thereby solving the problem in the prior art that the electrode sheets are exposed, resulting in the inability to ensure electricity safety.

[0027] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a plastic support seat for a PTC heater terminal, comprising a plug 1 and a socket 2, a heat conducting pipe placement groove 8 is provided at the bottom of the side of the plug 1, two electrode sheet placement grooves 3 and a wire placement groove 4 are provided directly above the heat conducting pipe placement groove 8, and the wire placement groove 4 is located between the two electrode sheet placement grooves 3, which are symmetrically arranged;

[0028] A wire hole 401 communicating with the wire placement slot 4 is provided at the top of the plug 1. During installation, the wire is placed in the wire placement slot 4, and the wire is led out through the wire hole 401 and connected to an external power source.

[0029] like Figure 3 As shown, the heat pipe placement groove 8 is connected to the two electrode sheet placement grooves 3. During installation, the PTC heater heat pipe is installed in the heat pipe placement groove 8, and the two electrode sheets connected to the heating core in the PTC heater heat pipe are respectively installed in the electrode sheet placement grooves 3. In this solution, since there is a wire placement groove 4 in the middle of the two electrode sheet placement grooves 3, the two electrode sheets are installed separately to avoid contact, and thus the positive and negative short circuit phenomenon will not occur during use, thereby improving the safety factor.

[0030] To prevent the electrode from loosening after installation, Figure 3 and Figure 4As shown, a plastic pressing block 5 is arranged on the top of the electrode sheet placement groove 3, and a threaded hole is opened directly above the electrode sheet placement groove 3, in which a screw rod 501 is movably screwed. After the electrode sheet is installed, the screw rod 501 is rotated by a corresponding tool. Since the bottom end surface of the screw rod 501 is in contact with the top end surface of the pressing block 5, when the screw rod 501 moves downward, it drives the pressing block 5 to move downward until the electrode sheet is squeezed.

[0031] In addition, the sides of the two electrode sheet placement grooves 3 are respectively provided with a fuse placement groove 6 for installing a fuse and a thermostat placement groove 7 for installing a thermostat. The above-mentioned electrode sheets, PTC heater heat pipes, fuses and thermostats are connected through corresponding wires.

[0032] In order to facilitate the fixing of the plug 1 and the socket 2, as Figure 2 As shown, a sub-card connector 101 is integrally formed on one side of the plug 1, a vertical plate 203 is integrally formed on the inner side of the socket 2, and a slot adapted to the sub-card connector 101 is formed between the vertical plate 203 and the inner wall of the socket 2, a female card connector 204 is integrally formed at the bottom of the vertical plate 203, and the female card connector 204 and the sub-card connector 101 are engaged with each other. During installation, the socket 2 is inserted downward from the top of the plug 1 until the female card connector 204 and the sub-card connector 101 are engaged together. This connection method is a conventional installation method in the technical field, and the specific structure and installation process of the female card connector 204 and the sub-card connector 101 will not be repeated here.

[0033] In order to improve the connection stability between the plug 1 and the socket 2, a plurality of groups of interconnected fixing holes 9 are opened on the sides of the plug 1 and the socket 2. In this way, when the mother card connector 204 and the child card connector 101 are connected, the plug 1 and the socket 2 are further fixed by screws.

[0034] To facilitate the installation of the support seat, Figure 1 and Figure 2 As shown, a mounting plate 201 is fixed at the bottom of the socket 2. During installation, the mounting plate 201 is fixed to the corresponding position of the heating device by screws.

[0035] In addition, if Figure 2 As shown, in order to prevent the socket 2 from falling off due to vibration of the heating equipment, in a specific embodiment of the present scheme, a rectangular groove is opened at the bottom end of the mounting plate 201, and an elastic pad 202 is fixed in the rectangular groove. It can be seen that the bottom end surface of the elastic pad 202 protrudes from the rectangular groove.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
