Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a leakage protector and a socket equipped with the leakage protector. Background Art

[0002] The leakage protector is an indispensable supporting device for electrical appliance protection. Among them, the small leakage protector is particularly widely used, especially in power lines with low power but requiring end leakage protection such as switches, sockets or extension strips. When the electrical appliance has a leakage, it can quickly cut off the power supply.

[0003] However, the existing leakage protector has a non-compact structure and a large volume, which results in an increase in the volume of electrical equipment using the leakage protector. Utility Model Content

[0004] The utility model aims to provide a leakage protector to optimize the structure of the existing leakage protector.

[0005] Another object of the utility model is to provide a socket equipped with a leakage protector as described above, so as to reduce the volume of equipment using the leakage protector.

[0006] To achieve the first purpose, the utility model provides the following technical solutions: a leakage protector, comprising a shell and a tripping device installed inside the shell; the tripping device comprises an electromagnetic coil installed on one side of the shell and a mutual inductor installed on the other side of the shell, and the mutual inductor is fixed in the shell by a circuit board; the tripping device also comprises an integral moving contact and a static contact and a driving mechanism for driving the moving contact and the static contact to separate and close.

[0007] As a preferred technical solution of the utility model: one end of the static contact is provided with an introduction end for introducing power into the circuit board, and the introduction end is fixed on the upper surface of the circuit board.

[0008] As a preferred technical solution of the utility model: the lead-in end is fixedly connected to the circuit board; and the bottom surface of the shell is also provided with a lead-out end for leading out the power supply entering the circuit board.

[0009] As a preferred technical solution of the utility model: one side of the shell is provided with a fixing area for fixing the mutual inductor, and the other side of the shell is provided with an assembly area for assembling the electromagnetic coil.

[0010] As a preferred technical solution of the utility model: the moving contact and the static contact are in a V shape.

[0011] As a preferred technical solution of the utility model: the driving mechanism includes a pressure block, pressure rods arranged on both sides of the pressure block, and the pressure rods abut against the moving contact, and the pressure block is linked to a reset rod, and the other end of the reset rod is connected to a reset button.

[0012] As a preferred technical solution of the utility model: a test button is also integrated on the circuit board, and an indicator light is integrated on the circuit board between the test button and the reset button.

[0013] To achieve another purpose, the utility model provides the following technical solution: a socket, comprising a front panel and a back panel, and a leakage protector as described above is placed between the back panel and the front panel.

[0014] Further: the leakage protector is connected to a connection piece through an introduction end, and the other end of the leakage protector is connected to a connector through an outlet end, and a socket is provided on the panel to facilitate the connection of a plug with the connector.

[0015] Furthermore: the panel is also provided with a clearance hole and a through hole, and a light hole is provided between the clearance hole and the through hole to facilitate the display of light.

[0016] By adopting the above technical solution, the utility model has the following beneficial effects: 1. Since the mutual inductor and the electromagnetic coil are respectively installed on two surfaces of the shell, the structure of the existing leakage protector is optimized, so that the structure of the device is compact and the volume is small, so that the length of the shell can be reduced, and then the length of the electrical equipment installed with the device can be reduced;

[0017] 2. Since the moving contact and the stationary contact of the device are an integrated structure, no additional power is required when the moving contact is separated from the stationary contact. For example, compared with the existing method, it is no longer necessary to use a spring to separate the moving contact from the stationary contact, thereby further optimizing the structure of the existing equipment. At the same time, the moving contact and the stationary contact of the integrated structure only require one installation position to achieve the installation and fixation of the moving contact and the stationary contact, thereby solving the problem that the existing equipment needs to set both the installation position of the moving contact and the installation position of the stationary contact on the shell.

DETAILED DESCRIPTION

[0026] The embodiments of the utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the utility model, and cannot be understood as limiting the utility model. In the description of the utility model, it should be understood that the orientation or position relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the utility model. In the utility model, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection, an electrical connection, or can communicate with each other; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] See also Figure 1-7 , an embodiment provided by the utility model, for details, see Figure 1-5As shown, a leakage protector is provided, the leakage protector 3 includes a shell 30 and a tripping device 316 installed inside the shell 30; the tripping device 316 includes an electromagnetic coil 313 installed on one side of the shell 30 and a mutual inductor 314 installed on the other side of the shell 30, and the mutual inductor 314 is fixed in the shell 30 through a circuit board 31; the tripping device 316 also includes an integral moving contact 38 and a stationary contact 315 and a driving mechanism for driving the moving contact 38 and the stationary contact 315 to separate and close.

[0028] Through the above scheme, the device arranges the electromagnetic coil 313 and the mutual inductor 314 on the two surfaces of the shell 30, so that the overall structure of the device is further optimized, especially compared with the existing equipment, the overall length is reduced, so it is convenient for the internal layout and installation of the device in the electrical equipment; at the same time, the moving contact 38 and the static contact 315 adopt an integrated structure, so after the static contact 315 is fixed, the moving contact 38 can be effectively fixed, so compared with the existing equipment, the shell 30 of the device no longer needs to be provided with a mounting hole for the moving contact 38, which can further optimize the overall structure of the device.

[0029] In addition, the working principle of the tripping device 316 and the driving mechanism of the device is consistent with the working principle of the Chinese patent with patent number CN 107818890A, so it will not be described in detail again.

[0030] In addition, one end of the static contact 315 is provided with an introduction end 310 for introducing power into the circuit board 31, and the introduction end 310 is fixed on the upper surface of the circuit board 31. Therefore, while realizing the introduction of power, the introduction end 310 can be set near the transformer 314, providing a wider operating space for the end of the static contact 315 away from the introduction end 310.

[0031] Furthermore, the lead-in end 310 is fixedly connected to the circuit board 31; the bottom surface of the housing 30 is also provided with a lead-out end 39 for leading out the power entering the circuit board 31;

[0032] Among them, the specific connection method is: it can be fixed by welding or by the following method, namely: a connecting hole 35 is also provided on the introduction end 310, and a bolt is passed through the connecting hole 35 to connect with the shell 30, so that the circuit board 31 is further fixed on the shell 30; through the above method, the circuit board 31 and the shell 30 can be further fixed, especially, without affecting the introduction of power supply, the fixed connection between the shell 30 and the circuit board 31 can be achieved, thereby solving the problem that the circuit board of the existing equipment is connected to the shell by a buckle, which causes the connection between the circuit board and the buckle to shake easily.

[0033] Since one side of the shell 30 is provided with a fixing area 36 for fixing the mutual inductor 314, and the other side of the shell 30 is provided with an assembly area 37 for assembling the electromagnetic coil 313, a reliable installation space is provided for the mutual inductor 314 and the electromagnetic coil 313, thereby ensuring that the two will not interfere with each other when working, and at the same time the volume of the shell 30 can be further reduced.

[0034] In order to further optimize the structure of the moving and static contacts of the existing equipment, the moving contact 38 and the static contact 315 are in a V-shape. Since the moving contact 38 and the static contact 315 of the device are in a V-shape, the moving contact 38 is separated from the static contact 315 in a free state, thereby further realizing the separation of the moving contact 38 and the static contact 315 without external power.

[0035] Among them, the main structure of the driving mechanism is as follows: the driving mechanism includes a pressure block 312, a pressure rod 311 arranged on both sides of the pressure block 312, and the pressure rod 311 contacts the moving contact 38, and the pressure block 312 is linked with a reset rod 317, and the other end of the reset rod 317 is connected to a reset button 32.

[0036] Since a test button 33 is also integrated on the circuit board 31, and an indicator light 34 is integrated on the circuit board 31 between the test button 33 and the reset button 32, through the above method, the test button 33 of the device can be implemented by a circuit structure, which solves the problem that the existing test button requires a mechanical structure to be implemented. In addition, the indicator light 34 is integrated between the test button 33 and the reset button 32, which further facilitates the user to check and avoids the problem of light being blocked.

[0037] like Figure 6-7 As shown, combined with Figure 1-5; The utility model also provides an embodiment: a socket, comprising a panel 2 and a back panel 1, and a leakage protector as described above is placed between the back panel 1 and the panel 2. Since the socket is installed with the leakage protector 3, the entire circuit is reliably protected when the socket is in use. At the same time, the optimized leakage protector 3 is easy to install in the socket, and the overall length and volume of the socket are smaller.

[0038] Furthermore, the leakage protector 3 is connected to the provided connector 4 through the lead-in end 310, and the other end of the leakage protector 3 is connected to the provided connector 5 through the lead-out end 39, and a socket 6 is provided on the panel 2 for facilitating the connection of a plug with the connector 5.

[0039] Furthermore, the panel 2 is also provided with a clearance hole 7 for exposing the reset button 32 outside the panel 2 and a through hole 8 for exposing the test button 34 outside, and a light hole 9 is provided between the clearance hole 7 and the through hole 8 to facilitate the display of light.

[0040] Through the above manner, the socket is small in size, easy to carry and use, and in particular, can also achieve circuit protection.

[0041] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
