[0002] The existing technology, Chinese patent 202321977288.9, describes an anti-electric shock wall connector structure and an electric water heater. The anti-electric shock wall connector structure includes a connector body, a first connector, and a second connector. The connector body has a water passage. The first connector is embedded at the first end of the water passage, and a first anti-rotation protrusion is provided on the outer periphery of the first connector to restrict its rotation around its axis. The second connector is embedded at the second end of the water passage, and a second anti-rotation protrusion is provided on the outer periphery of the second connector to restrict its rotation around its axis. The problem is that when the first connector expands and contracts thermally, a gap is created between the first connector and one end of the water passage, leading to water leakage through the gap.

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figure 1 As shown, an electric water heater connector includes a connector body 1 made of plastic material, an internally threaded interface component 2, an externally threaded interface pipe 3, and a sealing gasket 4.

[0023] The connector body 1 includes a polygonal part 11, a water channel 12, an inner countersunk hole 13, an annular pressure plate 14 disposed on the bottom plate of the inner countersunk hole 13, and an outer connector part 15. The water channel 12 communicates with the outer connector part 15 and the inner countersunk hole 13. There is a gap between the annular pressure plate 14 and the bottom plate of the inner countersunk hole 13. Alternatively, it can be described as follows: the water channel 12 is provided with an annular pressure plate 14 at one end inside the inner countersunk hole 13, and there is a gap between the annular pressure plate 14 and the bottom plate of the inner countersunk hole 13. The connector body 1 is integrally molded from plastic material.

[0024] One end of the internal threaded interface component 2 is provided with an annular seat plate 21.

[0025] The internal threaded interface 2 is embedded in the internal countersunk hole 13, the annular pressure plate 14 covers the annular seat plate 21, the sealing gasket 4 is placed on the annular pressure plate 14, and the external threaded interface pipe 3 is embedded in the external connector part 15.

[0026] As a further improvement of this utility model: the water channel 12 extends into the inner recess 13 to form a connector pipe 121; the connector pipe 121 passes through the sealing gasket 4; the connector pipe 121 can also extend out of the inner recess.

[0027] As a further improvement of this utility model: the internal thread interface component 2 is provided with a smooth cylinder 22 at one end of the annular seat plate 21, and the smooth cylinder 22 corresponds to the outer circumferential surface of the annular pressure plate 14.

[0028] As a further improvement of this utility model: the outer circumferential surface of the internal thread interface 2 is provided with an axial protrusion or an axial groove;

[0029] The annular seat plate 21 of the internal thread interface 2 may have radial protrusions or radial grooves; or the outer circumferential surface of the internal thread interface may be polygonal. This structure prevents the internal thread interface 2 from rotating relative to the countersunk hole.

[0030] One end of the externally threaded interface tube 3 is provided with several arc-shaped teeth 31, and the inner wall is provided with annular protrusions 32. This structure can prevent the externally threaded interface tube 3 from moving or rotating axially relative to the external connector 15.
