Description

Technical Field

[0001] The present disclosure relates to the field of leakage protection, and in particular, to a miniaturized leakage protector. Background Art

[0002] Traditional mobile leakage protectors are generally large in size, especially when connected to a cable. Even if the cable is rolled up, it is still difficult to store. For example, when a mobile leakage protector is used as an accessory to the power plug of an electric vehicle charger, when the electric vehicle is not charging, the mobile leakage protector needs to be stored in the helmet box of the electric vehicle. However, since the helmet box of some electric vehicles is relatively small, it may not be able to accommodate the mobile leakage protector. Therefore, it is necessary to propose a new solution to reduce the size of the existing leakage protector, that is, to propose a miniaturized and compact leakage protector. Utility Model Content

[0003] In order to solve at least part of the above technical problems, the present disclosure proposes a leakage protector with a hidden wire clip waterproof ring. The exposed wire clip waterproof ring of the leakage protector is shortened in length and hidden in the shell of the leakage protector to reduce the volume of the leakage protector.

[0004] In one embodiment of the present invention, a leakage protector is proposed, which includes a shell; a core assembly arranged in the shell; and a wire clamp waterproof ring, which is hidden in a through hole at the tail end of the shell and is used to fix the cable that enters the interior of the shell through the through hole to be electrically connected to the core assembly and to achieve waterproofing of the shell.

[0005] In a preferred implementation of this embodiment, the core assembly includes: a U-shaped input terminal and a PCB board, wherein the first end of the U-shaped input terminal is electrically connected to the PCB board, and the second end of the U-shaped input terminal abuts against the surface of the PCB board.

[0006] In a preferred implementation manner of this embodiment, the first end of the U-shaped input terminal is welded or riveted to the PCB board.

[0007] In a preferred implementation manner of this embodiment, the leakage protector includes: an inner cover, which is arranged in the shell, and the inner cover is provided with a wiring groove and a hook for wiring and fixing the ground wire.

[0008] In a preferred implementation manner of this embodiment, the shell includes an upper cover and a base, a shell waterproof ring is provided between the upper cover and the base, and the shell waterproof ring is provided with fixing wings for fixing the shell waterproof ring.

[0009] In a preferred implementation manner of this embodiment, the fixing wing includes a first fixing wing and a second fixing wing, and the first fixing wing and the second fixing wing are respectively arranged at two ends of the waterproof ring of the shell.

[0010] In a preferred implementation manner of this embodiment, at least one first waterproof rib is provided on the outer side of the wire clip waterproof ring.

[0011] In a preferred implementation manner of this embodiment, at least one second waterproof rib is provided on the inner side of the wire clip waterproof ring, wherein the second waterproof rib includes a triangular waterproof rib.

[0012] In a preferred implementation manner of this embodiment, the leakage protector includes: an inner cover, which is arranged in the shell; the movement component includes a reset trip component, and the inner cover is used to accommodate all the reset trip components.

[0013] In a preferred implementation manner of this embodiment, the leakage protector includes: an inner cover, which is arranged in the shell; the inner cover is provided with a plug power cord slot for fixing the plug power cord.

[0014] In summary, the present invention proposes a miniaturized, compact leakage protector (RCD) that reduces its size by concealing the wire clip waterproof ring within the device's housing. This improvement not only saves space and raw materials but also offers the advantage of ease of portability and storage when used in mobile products, such as accessories for electric vehicle chargers. This new RCD is suitable for a wider range of applications, particularly those requiring limited space. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In the following detailed description of the preferred embodiments, reference will be made to the accompanying drawings which form part of this disclosure. The accompanying drawings illustrate, by way of example, specific embodiments in which the present disclosure may be implemented. The illustrated embodiments are not intended to be exhaustive of all embodiments according to the present disclosure. It will be understood that other embodiments may be utilized and structural or logical modifications may be made without departing from the scope of the present disclosure. Therefore, the following detailed description is not restrictive, and the scope of the present disclosure is defined by the appended claims.

[0025] Before introducing the embodiments of the present disclosure, some terms involved in the present disclosure are first explained to facilitate a better understanding of the present disclosure.

[0026] The terms "one", "a group" or "an" and the like used in this disclosure do not indicate a quantitative limitation, but rather indicate the presence of at least one. The terms "include", "comprise" and similar terms used in this disclosure should be understood as open terms, i.e., "include / include but not limited to", indicating that other content may also be included. The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one other embodiment", and so on. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, unless they are mutually contradictory.

[0027] In order to solve the problem that the existing mobile leakage protector is large in size and inconvenient to store as mentioned above, the present disclosure proposes a new type of leakage protector. Specifically, the present disclosure is elaborated in detail below using the case where the mobile leakage protector is used as an accessory of the power plug of an electric vehicle charger as an example. However, it should be noted that the present disclosure does not limit the improvement to be used only for the power plug of an electric vehicle charger, but can also be used in other application scenarios where the size of the mobile leakage protector is restricted.

[0028] refer to Figures 1-8 An embodiment of the present disclosure provides a miniaturized leakage protector 100, wherein: Figure 1 is a front view of the leakage protector 100, Figure 2 Schematic diagram of the explosion of the leakage protector 100. Figure 3 This is a schematic diagram of the internal structure of the leakage protector 100 after removing the base. Figure 4 This is a schematic diagram of the partial structure of the leakage protector 100 including the input terminal. Figure 5 is a structural diagram of the input terminal of the leakage protector 100, Figure 6 This is a partial structural diagram of the leakage protector 100 including the ground line. Figure 7 This is a schematic diagram of the structure of the leakage protector 100 including the wire clip waterproof ring. Figure 8 Schematic diagram of the structure of the wire clip waterproof ring in the leakage protector 100.

[0029] like Figures 1-8 As shown, the leakage protector 100 includes a shell, a core assembly arranged in the shell, and a wire clip waterproof ring 110. In some examples, the shell includes an upper cover 120 and a base 130. The wire clip waterproof ring 110 is hidden in the through hole at the tail end of the shell (in some examples, the first wire clip waterproof ring semicircular groove 121 set at the tail end of the upper cover 120 and the second wire clip waterproof ring semicircular groove 131 set at the tail end of the base 130 cooperate to form the through hole). The wire clip waterproof ring 110 is used to fix the cable 140 that enters the interior of the shell through the through hole to be electrically connected to the core assembly and to achieve waterproofing of the shell. The front end of the shell of the leakage protector can be used for the plug power cord 150 to be inserted and connected.

[0030] like Figure 7 and 8 As shown, unlike the prior art in which the wire card waterproof ring is exposed to the shell and is longer, the length of the wire card waterproof ring 110 in this embodiment is greatly shortened and hidden in the shell. The entire wire card waterproof ring 110 is arranged at the tail end of the shell. The wire card waterproof ring is not exposed and has a hidden structure, which reduces the length and volume of the leakage protector and improves the convenience of carrying and storage.

[0031] In some examples, the outer side of the cable clamp waterproof ring 110 is provided with a first waterproof rib 111, which closely mates with the first cable clamp waterproof ring semicircular groove 121 in the upper cover 120 and the second cable clamp waterproof ring semicircular groove 131 in the base 130 to achieve waterproofing. The number of first waterproof ribs can be set as needed and can be one, two, three, or even more. Preferably, two first waterproof ribs 111 are provided on the outer side of the cable clamp waterproof ring 110 to improve sealing and waterproofing performance while minimizing the structure for ease of production.

[0032] In some examples, at least one second waterproof rib 113 is provided on the inner side of the cable clamp waterproof ring 110 to provide waterproof protection for the inner hole 115 and the cable 140. Preferably, the second waterproof rib is triangular, which helps improve the stability of the overall structure and reduces the impact of thermal expansion and contraction caused by environmental changes on waterproof performance. The number of second waterproof ribs can also be set as needed, and can be one, two, three, or even more.

[0033] like Figure 4 and Figure 5 As shown, in some examples, the core assembly includes a PCB board 160 and a U-shaped input terminal 170, wherein a first end 171 of the U-shaped input terminal 170 is electrically connected to the PCB board 160, and a second end 173 of the U-shaped input terminal 170 abuts against the surface of the PCB board 160. The U-shaped input terminal 170 can be a live wire input terminal (live wire input plate) and a neutral wire input terminal (neutral wire input plate), which can be respectively arranged in corresponding input plate slots 175. Due to the long cantilever of the live wire input terminal and the neutral wire input terminal in the prior art, when one end is fixed, the terminal will deflect, so that the static contact on it will tilt with the cantilever, thereby affecting the power-on performance of the product. In this example, the live wire input terminal and the neutral wire input terminal are designed as a U-shaped structure, so that the first end 171 is electrically connected to the PCB board 160 (which can be welded, riveted or other connection methods), and the second end 173 rests on the surface of the PCB board 160 to provide support, thereby avoiding structural instability of the input terminal due to excessive cantilever, that is, avoiding tilting of the terminal, thereby improving the structural stability and power-on performance of the product.

[0034] like Figure 2 As shown, in some examples, the leakage protector 100 further includes an inner cover 180. The inner cover 180 is disposed inside the housing, that is, inside the accommodating cavity formed by the upper cover 120 and the base 130. In some examples, the inner cover 180 is provided with a wiring groove 181 and a hook 183 for routing and fixing the ground wire. Specifically, in some examples, the ground wire 141 is led out from the open end 185 of the inner cover 180, then passes through the wiring groove 181 (ground wire clip groove) and is fixed by the hook 183, and finally passes through the end through hole of the wiring groove 181 and is soldered to the ground wire soldering hole 161 of the PCB board 160.

[0035] like Figure 2 As shown, in some examples, the leakage protector 100 further includes a shell waterproof ring 190. The shell waterproof ring 190 is provided between the upper cover and the base of the shell, and the shell waterproof ring 190 is provided with a fixing wing 191 for fixing the shell waterproof ring. Specifically, as shown in FIG. Figure 3As shown, in some examples, the housing waterproof ring 190 is inserted into the corresponding slots in the upper cover before the inner cover 180 is assembled to the upper cover 120. In some examples, the fixing wings 191 include a first fixing wing and a second fixing wing, which are respectively provided at the ends of the housing waterproof ring 190. The length of the fixing wings is adapted to the depth of the corresponding slots in the upper cover. The deeper the first and second fixing wings at the ends are inserted into the corresponding slots in the upper cover, the less likely the housing waterproof ring 190 will fall off during wiring, thereby securing the housing waterproof ring.

[0036] like Figure 2 、 3 As shown in Figure 6, the inner cover 180 houses all reset and trip components (all parts of the reset and trip mechanism). In conventional leakage protectors, the reset and trip components are primarily located within the base of the housing. This embodiment places all reset and trip components within the inner cover, making the product more compact, further conserving internal space, and reducing the size of the product.

[0037] like Figure 3 and Figure 6 As shown, in some examples, the inner cover 180 is provided with a plug power cord retaining slot 187 for securing the plug power cord 150. Securely inserting the plug power cord into the inner cover's plug power cord retaining slot 187 prevents the plug power cord from loosening, improving the product's structural stability and power supply performance, and further compacting the inner cover and plug power cord. In some examples, the front end of the base 130 is provided with a semicircular power plug cord retaining slot 133 for accommodating and securing the plug power cord 150.

[0038] Reference Figure 2 、 3and 6. The assembly method of the leakage protector 100 includes: first, assembling all the reset trip components on the inner cover 180; then, aligning the corresponding holes on the PCB board 160 with the pins of the reset trip components and covering the inner cover, and soldering the corresponding pins to achieve electrical connection; then, leading the ground wire 141 from the open end 185 of the inner cover, then passing through the wiring groove 181 and being fixed by the hook 183, and finally passing through the end through hole 1811 (ground wire through hole) of the wiring groove 181 and soldering it to the ground wire soldering hole 161 of the PCB board 160; then, soldering the neutral and live wires of the plug power cord 150 to the corresponding neutral and live wire input terminals on the PCB board 160. After soldering is completed, the plug power cord is installed in the plug power cord slot 187 of the inner cover and fixed; finally, using screws 201 to pass through the screw mounting holes 189 on the inner cover to fix the inner cover assembly to the upper cover 120. In some examples, when wiring is required, the cable 140 is passed through the wire clamp waterproof ring 110, and then the live wire, neutral wire and ground wire in the cable 140 are respectively connected to the live wire output piece assembly 203, the neutral wire output piece assembly 205, and the ground wire output piece assembly 207, and then the cable 140 is fixed with the wire pressing block 209 and the wire pressing block screw 211, and finally fixed to the base 130 by the assembly screw 213, thereby completing the assembly of the product.

[0039] like Figure 1-8 As shown, in some examples, the leakage protector 100 also includes a reset button 127 and a test button 129, which are arranged corresponding to the reset button guide hole 123 and the test button guide hole 125 on the upper cover 120, and a button waterproof pad 128 is provided under the reset button 127 and the test button 129.
