Problems solved by technology

In order to prevent loosening between the plug and the socket, the coupling connectors on the market mainly prevent the separation of the plug and the socket through the friction between the outer wall of the plug and the inner wall of the socket, but it is particularly laborious when the plug is inserted and pulled out.
Especially for the coupling connector on the liquid heater, after the heating of the liquid heater is completed, a large inertial force will be generated when the plug is pulled out, which will easily cause the water in the liquid heater to oscillate and burn the user

Embodiment 1

[0037] Such as Figure 1 to Figure 7 As shown, this embodiment provides a plug-in connector, including a plug 1 and a socket 2 with a slot 21, the socket 2 is mated with the plug 1 through the slot 21, and after the plug is inserted into the slot, the plug The relative socket is non-rotatable, and there is an anti-off structure between the socket 2 and the plug 1 to prevent the plug 1 from being loosened from the socket 21. The plug 1 has multiple insertion orientations relative to the socket 21. The plug 1 and the socket 2 One of them is provided with a first ground wire 11 , and the other is provided with a second ground wire 12 , and the first ground wire 11 and the second ground wire 12 can be electrically contacted when the plug 1 is in different insertion orientations.

[0038]First of all, the socket 2 is mated with the plug 1 through the slot 21, which increases the mating area between the plug 1 and the socket 2, facilitates the contact between the neutral wire, live ...

Embodiment 2

[0050] Of course, the first ground piece 11 may no longer be provided with a plurality of independent contact pieces 111 in contact with the conductive piece 121, but the first ground piece 11 has a contact ring sleeved on the outside of the plug 1, and the second ground piece The piece 12 has a conductive piece 121 protruding into the slot 21 , and the contact ring is in electrical contact with the conductive piece 121 when the plug 1 is mated with the slot 21 . Since the contact ring is a continuous closed ring, no matter what direction the plug 1 is plugged in, it can ensure that the conductive piece 121 is in contact with the contact ring, and the user's plugging operation is more convenient. At the same time, the contact ring is sleeved on the plug 1 Not only is the installation more convenient, but also the overall strength and aesthetics are good after the cooperation of the two.

[0051] It can be understood that the first ground piece 11 can also be arranged on the so...

Embodiment 3

[0054] In addition to the magnetic force anti-off in the first embodiment, the plug 1 and the socket 2 can also include a detachable first buckle and a second buckle, the first buckle and the second buckle One is set on the socket 2 and the other is set on the plug 1. The anti-loosening structure prevents the plug 1 from being loosened from the socket 21 through the fastening force between the first buckle and the second buckle. The fastening force between the first buckle position and the second buckle position is large, and the anti-loosening effect is good. At the same time, the plug-in fastening feels good, and it is convenient for the user to perceive whether the current plug 1 is inserted in place.

[0055] For other content not described in this embodiment, reference may be made to Embodiment 1.

Abstract

The invention discloses a plug-in type connector and a liquid heater. The plug-in type connector comprises a plug and a socket with a slot, the socket is in plug-in fit with the plug through the slot, an anti-loosening structure for preventing the plug and the slot from loosening in plug-in is arranged between the socket and the plug, and the plug has a plurality of plug-in directions relative to the slot. One of the plug and the socket is provided with a first ground wire sheet, the other one of the plug and the socket is provided with a second ground wire sheet, the first ground wire sheet and the second ground wire sheet can be electrically contacted when the plug is in different plugging directions, and after the plug is inserted into the slot, the plug cannot rotate relative to the socket. According to the invention, the anti-loosening structure between the plug and the socket can prevent the plug and the slot from being plugged and matched to be loosened, the first ground wire sheet and the second ground wire sheet can be electrically contacted when the plug is in different plugging orientations, a user can realize the electrical contact between the plug and the socket without identifying the plugging orientation, and the operation is simple.

Description

technical field [0001] The invention relates to the technical field of home appliances, in particular to a plug-in connector and a liquid heater with the above-mentioned plug-in connector. Background technique [0002] The coupling connector includes a plug and a socket with a slot, and the socket is mated with the plug through the slot, so that the zero line contact piece, the live line contact piece and the ground line piece on the plug are respectively in contact with the neutral line contact piece and the live line on the socket. Sheet and ground sheet are in electrical contact. In order to prevent loosening between the plug and the socket, coupling connectors on the market mainly prevent the separation of the plug and the socket by the friction between the outer wall of the plug and the inner wall of the socket, but it is particularly laborious when plugging and unplugging the plug. In particular, for the coupling connector on the liquid heater, after the liquid heater...
