DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0035] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0036] In the related art, when the electronic circuit breaker is in use, water easily seeps into the shell from the connection point. Moreover, the water seeping from the connection point can directly contact the circuit of the electronic circuit breaker, thereby damaging the control circuit in the electronic circuit breaker, causing the electronic circuit breaker to trip by mistake, or failing to trip according to the preset conditions.

[0037] In view of the above problems, the present application provides an electronic circuit breaker. The electronic circuit breaker separates the space for installing the wiring terminals from the space for installing the control circuit. In this way, even if water seeps into the wiring terminals, it cannot contact the control circuit, thereby protecting the control circuit and improving the waterproof performance of the electronic circuit breaker.

[0038] The following is combined with Figures 1 to 11 , the electronic circuit breaker provided in the embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0039] Reference Figure 1 and Figure 2 The electronic circuit breaker provided in the present application includes a housing 100, a terminal 200 and a control circuit. The housing 100 is a basic structural component and can provide a mounting base for other components.

[0040] Reference Figure 2 In some embodiments, a partition 110 is provided in the housing 100, and the partition 110 is used to separate and form a wiring sealed cavity 101 and an electric control sealed cavity 102. Exemplarily, a wiring terminal 200 is provided in the wiring sealed cavity 101, and the electronic circuit breaker is connected to an external circuit through the wiring terminal 200. Exemplarily, the wiring terminal 200 can be a wiring terminal. Specifically, this embodiment does not limit the specific type of the wiring terminal 200.

[0041] In some optional embodiments, the control circuit is disposed in the electric control sealed chamber 102. The control circuit is connected to the terminal 200, and the control circuit can control the on and off of the line passing through the electronic circuit breaker. Figure 3 and Figure 4 As shown, the electronic circuit breaker further includes a circuit board 500. For example, the control circuit can be integrated into the circuit board 500 and then arranged in the electric control sealed cavity 102 to improve the compactness of the arrangement between the components in the control circuit and reduce the space occupied by the electric control sealed cavity 102. Of course, the control circuit can also be arranged in the electric control sealed cavity 102 in other forms. For this reason, this embodiment does not limit the installation form of the control circuit in the electric control sealed cavity 102.

[0042] In the above-mentioned embodiment, the wiring sealed cavity 101 is beneficial to prevent liquid from entering and contacting the terminal 200, and is further beneficial to protecting the reliability of the connection between the terminal 200 and the external circuit. However, the standardization of the wiring between the external circuit and the terminal 200 and the repeated disassembly of the external connection circuit during the maintenance process may affect the sealing performance of the wiring sealed cavity 101. Therefore, in some extreme cases, the sealing performance of the wiring sealed cavity 101 is poor due to the irregular wiring, which makes it easy for liquid to enter the wiring sealed cavity 101. In the circuit breaker provided in the present application, the control circuit and the terminal 200 are respectively arranged in different sealed cavities. In this way, even if liquid enters the wiring sealed cavity 101 due to the operator's irregular wiring during the installation of the electronic breaker, it can also prevent the liquid from contacting the control circuit, which is beneficial to protecting the control circuit and improving the waterproof performance of the electronic circuit breaker. In addition, the shell part forming the electric control sealed cavity 102 will not be disassembled during the installation of the electronic circuit breaker, which is beneficial to prevent the sealing performance of the electric control sealed cavity 102 from being damaged during the installation of the electronic circuit breaker, thereby ensuring the sealing performance of the electric control sealed cavity 102 and improving the reliability of the sealing performance of the electronic circuit breaker.

[0043] According to some optional embodiments, referring to Figure 2 and Figure 3 The partition 110 has a wire passage 111. The wire passage 111 is used to install a line connecting the control circuit and the terminal 200. Exemplarily, the wire passage 111 can be a through hole or a through groove that passes through the partition 110, so that the line connecting the control circuit and the terminal 200 can pass through the partition 110 along the wire passage 111.

[0044] Reference Figure 2 and Figure 3 In some optional embodiments, the spacing between the line passage 111 and the bottom wall of the wiring sealed chamber 101 is greater than zero. In this way, the liquid entering the wiring sealed chamber 101 will first gather at the bottom of the wiring sealed chamber 101, which is beneficial to prevent the liquid entering the wiring sealed chamber 101 from entering the electrical control sealed chamber 102. It should be noted that even in some extreme cases, such as when the operator's wiring operation is not standardized, resulting in poor sealing performance of the wiring sealed chamber 101. The holes connecting the wiring sealed chamber 101 to the outside are relatively small, and the liquid that is immersed in the wiring sealed chamber 101 from the outside will not be too much. Therefore, the immersed liquid can be gathered through the bottom space of the wiring sealed chamber 101 to prevent the liquid from being immersed in the electrical control sealed chamber 102.

[0045] In some optional embodiments, the circuit connecting the terminal 200 and the control circuit is sealed with the wire-through channel 111 to realize that the wiring sealed chamber 101 and the electric control sealed chamber 102 form a mutually independent sealed space. In this way, even if the wiring sealed chamber 101 is immersed in liquid, it will not be immersed in the electric control sealed chamber 102. Exemplarily, a seal can be provided in the wire-through channel 111 so that the gap between the circuit connecting the terminal 200 and the control circuit and the inner wall of the wire-through channel 111 is sealed by the seal. Specifically, the seal can be a sealing ring and / or a thermoplastic sprayed in the wire-through channel 111.

[0046] According to some optional embodiments, Figure 2 and Figure 3 As shown, the housing 100 includes a main body 120 and a first cover body 130. The wiring sealed chamber 101 and the electric control sealed chamber 102 are formed in the main body 120, and the main body 120 has an installation opening 121. The installation opening 121 is connected to the wiring sealed chamber 101 and / or the electric control sealed chamber 102. The first cover body 130 covers the main body 120, and the first cover body 130 seals the installation opening 121. Exemplarily, the first cover body 130 can be detachably connected to the main body 120 to facilitate the inspection of components in the wiring sealed chamber 101 and / or the electric control sealed chamber 102.

[0047] In some optional embodiments, the electronic circuit breaker has an operation button and an indicator light. Exemplarily, the operation button and the indicator light are arranged on the top wall of the main body 120, so that multiple electronic circuit breakers can be installed side by side in a horizontal manner.

[0048] In some optional embodiments, the installation opening 121 is provided on the side wall of the main body 120 to facilitate the disassembly and assembly of the electronic circuit breaker. This is beneficial for arranging the operation buttons and / or indicator lights in the control circuit on the main body 120 to facilitate the disassembly and assembly of the first cover 130.

[0049] Of course, in some optional embodiments, the installation opening 121 may also be disposed on the top wall or the bottom wall of the main body 120. For this reason, this embodiment does not limit the specific position of the main body 120 where the installation opening 121 is disposed.

[0050] Reference Figure 3, the wire-passing channel 111 is a groove provided on the partition 110, and the notch of the groove is opposite to the installation port 121. Exemplarily, the partition 110 can be an integral structure with the main body 120, or a separate structure with the main body 120. In an optional embodiment, the number of partitions 110 can be multiple. Exemplarily, part of the partition 110 can be an integral structure with the main body 120. Of course, part of the partition 110 can be separately provided with the main body 120. In some optional embodiments, when the partition 110 and the main body 120 are separately provided, a seal can be provided between the partition 110 and the main body 120 to seal the assembly gap between the partition 110 and the main body 120. Exemplarily, the assembly gap between the partition 110 and the main body 120 can be sealed by hot melt adhesive.

[0051] In the above embodiment, the notch of the groove forming the wire passage 111 is opposite to the installation opening 121 , which is beneficial to reduce the difficulty of installing the line connecting the control circuit and the wiring terminal 200 .

[0052] Reference Figure 2 and Figure 3 In some optional embodiments, the electronic circuit breaker further includes a connector 600. Exemplarily, the connector 600 passes through the wire passage 111 and is respectively connected to the control circuit and the terminal 200 to achieve electrical connection between the control circuit and the terminal 200. In some optional embodiments, the connector 600 may be a metal sheet. During installation, the shape of the connector 600 may be preset as required so that the connector 600 may be aligned with the wire passage 111 when the control circuit and / or the terminal 200 is aligned with the main body 120, thereby reducing the difficulty of assembling the electronic circuit breaker.

[0053] In some further optional embodiments, the thickness direction of the portion of the connector 600 located in the wire passage 111 is the first direction. The direction from the bottom of the wiring sealed cavity 101 to the top of the wiring sealed cavity 101 is the second direction. The first direction and the second direction are the same. In this way, it is beneficial to reduce the width of the wire passage 111 and to prevent liquid from entering the electric control sealed cavity 102 from the wire passage 111.

[0054] In some optional embodiments, the distance between the wiring terminal 200 and the bottom of the wiring sealed cavity 101 is greater than zero. In this way, when some liquid enters the wiring sealed cavity 101, the bottom of the wiring sealed cavity 101 can be used to accommodate some of the liquid, thereby preventing the liquid from entering the wiring sealed cavity 101 and facilitating contact with the wiring terminal 200, thereby improving the waterproof performance of the wiring terminal 200.

[0055] Reference Figures 6 to 8In some optional embodiments, one of the main body 120 and the first cover body 130 has a sealing groove 122, and the other has a first sealing protrusion 131. The first sealing protrusion 131 is configured to fit into the sealing groove 122. Specifically, when the first cover body 130 covers the main body 120, the first sealing protrusion 131 is at least partially embedded in the sealing groove 122 and is sealed with the sealing groove 122, and the first sealing protrusion 131 and the sealing groove 122 form a sealing fitting portion around the installation port 121. In this embodiment, the sealing fitting portion refers to the sealing portion where the first sealing protrusion 131 and the sealing groove 122 fit together.

[0056] In some optional embodiments, such as Figure 7 As shown, the main body 120 is provided with a sealing groove 122. Figure 8 As shown, the first cover portion 130 is provided with a first sealing protrusion 131. Exemplarily, the sealing groove 122 surrounds the installation opening 121. When the first cover portion 130 covers the main body 120, the first sealing protrusion 131 and the sealing groove 122 form a sealing surface surrounding the installation opening 121.

[0057] In the above embodiment, the first sealing protrusion 131 is embedded in the sealing groove 122 and sealed with the sealing groove 122, which is beneficial to improving the reliability of the sealing cooperation between the first cover body 130 and the main body 120, and further beneficial to preventing liquid from entering the wiring sealing cavity 101 and / or the electrical control sealing cavity 102 from the assembly point of the first cover body 130 and the main body 120.

[0058] In some optional embodiments, a sealing ring is provided in the sealing groove 122. When the first cover body 130 covers the main body 120, the first sealing protrusion 131 stops against the sealing ring in the sealing groove 122, so that the sealing ring can respectively seal with the first sealing protrusion 131 and the inner wall of the sealing groove 122, thereby improving the sealing performance between the first cover body 130 and the main body 120.

[0059] In some optional embodiments, the electronic circuit breaker includes a plurality of wiring terminals 200. The housing 100 has a plurality of wiring sealed cavities 101. The wiring sealed cavities 101 are independent of each other. The wiring terminals 200 are arranged one by one with the wiring sealed cavities 101. In some optional embodiments, two adjacent wiring sealed cavities 101 may be separated by, but not limited to, a partition 110.

[0060] In the above embodiment, the wiring terminals 200 are arranged in one-to-one correspondence with the wiring sealed chambers 101, so that the wiring terminals 200 can be physically separated by the partition 110 in the housing 100 to improve the safety and reliability of the electronic circuit breaker.

[0061] In some optional embodiments, the terminal 200 has one or at least two wiring parts, and the terminal 200 can be connected to an external circuit through at least one wiring part. In this way, the wiring section 200 can be connected to different numbers of external circuits according to actual needs. In some optional embodiments, the terminal 200 can be connected to at least two external cables at the same time. Exemplarily, the terminal 200 has a first wiring part and a second wiring part, and the terminal 200 can be connected to an external circuit through the first wiring part and / or the second wiring part. Exemplarily, the first wiring part and the second wiring part can be, but are not limited to, plug holes or slots provided on the terminal 200.

[0062] In the above embodiment, the number of cables connected to the wiring terminal 200 can be set as needed, so that the wiring can be paralleled and divided. For example, the wiring terminal 200 can be used for 1.5-4 (mm²) wires.

[0063] In some optional embodiments, such as Figure 3 and Figure 4 As shown, the electronic circuit breaker further includes a first sealing member 300. The housing 100 has a wiring port 103. The wiring port 103 penetrates the cavity wall of the wiring sealed cavity 101 and communicates with the wiring sealed cavity 101, so that the cable of the external circuit can pass through the wiring sealed cavity 101 along the wiring port 103 and connect to the wiring terminal 200 in the wiring sealed cavity 101. In some optional embodiments, the wiring port 103 is opposite to a wiring terminal 200 in the wiring sealed cavity 101, so as to facilitate the connection of the external cable to the wiring terminal 200 in the wiring sealed cavity 101. Exemplarily, one wiring port 103 can be opposite to one or more wiring portions of the same wiring terminal 200.

[0064] Reference Figure 4 In some optional embodiments, at least two wiring ports 103 are correspondingly provided in one wiring sealed cavity 101. Exemplarily, the wiring ports 103 corresponding to the same wiring sealed cavity 101 are all opposite to the wiring terminals 200 in the wiring sealed cavity 101, so that the external cables can be inserted into the wiring sealed cavity 101 along the wiring ports 103 and connected to the wiring terminals 200 in the wiring sealed cavity 101. In some optional embodiments, the wiring ports 103 corresponding to the same wiring sealed cavity 101 correspond one-to-one to the wiring parts of the wiring terminals 200 in the wiring sealed cavity 101, so as to realize the paralleling and branching of wires.

[0065] In some optional embodiments, the first seal 300 is disposed at the wiring port 103, and the first seal 300 can be respectively sealed with the housing 100 and the cable connected to the wiring terminal 200. Exemplarily, the first seal 300 can be, but is not limited to, a sealing ring, a sealing sleeve and / or a sealing gasket disposed at the wiring port 103.

[0066] In the above embodiment, the assembly gap between the external cable and the housing 100 can be sealed by the first sealing member 300 to ensure that the sealing performance of the wiring sealing cavity 101 can be maintained after the external cable is inserted into the wiring sealing cavity 101 .

[0067] In some optional embodiments, the first sealing member 300 has a wiring channel. Exemplarily, the external cable passes through the first sealing member 300 along the wiring channel and at least partially protrudes from the first sealing member 300 on the side facing the inside of the wiring sealing cavity 101, so that the external cable can be connected to the wiring terminal 200 in the wiring sealing cavity 101. Specifically, the cable in the wiring channel is interference-fitted with the wiring channel, so that the inner wall of the wiring channel can fit the outer peripheral wall of the cable and form a seal.

[0068] In some optional embodiments, the diameter of the wiring channel gradually decreases from one end of the wiring channel away from the wiring sealing cavity 101 to one end of the wiring channel close to the wiring sealing cavity 101. This is not only beneficial to the insertion of external cables, but also beneficial to improving the sealing performance between the first sealing member 300 and the cable.

[0069] In some optional embodiments, the inner wall of the wiring channel has an annular sealing protrusion. When an external cable is inserted into the wiring channel, the annular protrusion surrounds the outer peripheral wall of the cable and abuts against the outer peripheral wall of the cable to form an annular seal, thereby improving the sealing performance between the first sealing member 300 and the cable.

[0070] In some optional embodiments, the first seal 300 is made of an elastic material. Exemplarily, the first seal 300 switches between the first state and the second state. Exemplarily, when the first seal 300 is in the first state, the wiring channel is in a closed state. When the first seal 300 is in the second state, the wiring channel is a hole that runs through the first seal 300. Exemplarily, the first seal 300 can be deformed by inserting a cable, thereby switching the first seal 300 from the first state to the second state. After the cable is pulled out of the wiring channel, the first seal 300 can restore the deformation, thereby switching from the second state to the first state.

[0071] In the above embodiment, the first sealing member 300 can seal the wiring port 103 when there is no wiring at the wiring port 103 , thereby being beneficial to improving the sealing performance of the electronic circuit breaker.

[0072] In some optional embodiments, a sealing film is provided in the wiring channel of the first sealing member 300, and the sealing film blocks the wiring channel. Exemplarily, during the process of inserting the cable into the wiring channel, the cable can pierce the sealing film, so that the cable can be inserted into the wiring sealing cavity 101 and connected to the wiring terminal 200 in the wiring sealing cavity 101. In this way, the first sealing member 300 can achieve sealing of the wiring port 103 when there is no wiring at the wiring port 103, thereby being beneficial to improving the sealing performance of the electronic circuit breaker.

[0073] In some optional embodiments, referring to Figure 3 and Figure 4 , the outer peripheral wall of the end of the first sealing member 300 away from the terminal 200 has an annular protrusion. The annular protrusion stops at the outer side wall of the main body 120. In an optional embodiment, the outer side wall of the main body 120 has a receiving groove, and at least part of the annular protrusion is located in the receiving groove. In some further optional embodiments, the housing 100 also includes a second cover body 160. The second cover body 160 covers the side of the main body 120 where the wiring port 103 is provided. Exemplarily, the second cover body 160 stops at the end face of the end of the first sealing member 300 away from the terminal 200. In some optional embodiments, the second cover body 160 stops at the side of the annular protrusion away from the terminal 200, so that the second cover body 160 and the first sealing member 300 are sealed and matched.

[0075] In some optional embodiments, referring to Figure 4 , the electronic circuit breaker includes two groups of independent wiring sealed chambers 101. One group of wiring sealed chambers 101 is located on the first side of the electric control sealed chamber 102, and is used to install the wiring terminals 200 connected to the incoming circuit. The other group of wiring sealed chambers 101 is located on the second side of the electric control sealed chamber 102, and is used to install the wiring terminals 200 connected to the outgoing circuit. Exemplarily, each group of wiring sealed chambers 101 includes at least one wiring sealed chamber 101. In an optional embodiment, each group of wiring sealed chambers 101 includes two wiring sealed chambers 101. Specifically, one wiring sealed chamber 101 is used to install the wiring terminal 200 connected to the neutral wire, and the other wiring sealed chamber 101 is used to install the wiring terminal 200 connected to the live wire.

[0076] In some optional embodiments, such as Figure 4 As shown, the first side of the electrically-controlled sealed cavity 102 is opposite to the second side of the electrically-controlled sealed cavity 102 .

[0077] In the above embodiment, the wiring terminal 200 for connecting the incoming circuit and the wiring terminal 200 for connecting the outgoing circuit are respectively arranged on different sides of the electric control sealed cavity 102, which is beneficial to the wiring of the incoming circuit and the outgoing circuit.

[0078] In some other optional embodiments, the first side of the electrically controlled sealed cavity 102 is adjacent to the second side of the electrically controlled sealed cavity 102. Exemplarily, when the location where the electronic circuit breaker is installed for external circuit wiring needs to be diverted for wiring, the electronic circuit breaker can be used to achieve the diversion of the external circuit wiring. Specifically, when the electronic circuit breaker is used in the existing space and needs to be set in a corner position in order to save space, the electronic circuit breaker provided by this embodiment can be used, which is beneficial to reduce the difficulty of external circuit wiring and reduce the installation space of the electronic circuit breaker.

[0079] In some optional embodiments, two groups of independent wiring sealed chambers 101 are respectively arranged on opposite sides of the first direction of the electric control sealed chamber 102 to facilitate external circuit wiring. In some optional embodiments, the wiring port 103 is arranged on the side of the wiring sealed chamber 101 away from the electric control sealed chamber 102. In this way, multiple electronic circuit breakers can be spliced ​​and installed on opposite sides of the second direction of the electric control sealed chamber 102. Among them, the second direction of the electric control sealed chamber 102 is perpendicular to the first direction of the electric control sealed chamber 102.

[0080] Reference Figure 3 , Figure 4 , Fig. 9 According to some optional embodiments, the electronic circuit breaker further includes a second sealing member 400. The housing 100 has a tension adjustment opening 104. Exemplarily, the tension adjustment opening 104 penetrates the cavity wall of the wiring sealed cavity 101 and communicates with the wiring sealed cavity 101, and the tension adjustment opening 104 is opposite to the wiring terminal 200, so as to adjust the reliability of the connection between the cable of the external circuit and the wiring terminal 200 through the tension adjustment opening 104.

[0081] For example, Figure 4 , Figure 5 and Fig.11 As shown, the terminal 200 includes a fastener 210 and a connecting terminal 220. Exemplarily, the fastener 210 is connected to the connecting terminal 220, and the fastener 210 and the connecting terminal 220 are threadedly matched to fix the cable and the connecting terminal 220 inserted into the wiring sealing cavity 101 by twisting the fastener 210, so as to improve the reliability of the connection between the terminal 200 and the external circuit cable. Exemplarily, the fastener 210 can be but not limited to a screw. In an optional example, the tension adjustment port 104 is opposite to the fastener 210, so that the fastener 210 can be screwed by a screwdriver to tighten the cable and the terminal 220.

[0082] In some optional embodiments, the connection terminal 220 has a connection hole. At least a portion of the cable inserted into the wiring sealing cavity 101 is located in the connection hole, so that the fastener 210 can fasten the inserted cable and the connection terminal 220.

[0083] It should be noted that there are many types of terminal 200, and the terminal 200 disclosed in the drawings and the specification of this application is only used as an exemplary description. Therefore, this embodiment does not further limit the specific structure of the terminal 220.

[0084] In some optional embodiments, referring to Figure 1 and Fig. 9 , the second seal 400 is movably connected to the housing 100, and the second seal 400 can move between a first position and a second position relative to the housing 100. When the second seal 400 is in the first position relative to the housing 100, the second seal 400 seals the tension adjustment port 104. When the second seal 400 is in the second position relative to the housing 100, the second seal 400 deviates from the tension adjustment port 104. Exemplarily, the second seal 400 deviates from the tension adjustment port 104, which can be that the second seal 400 is detached from the housing 100, or the second seal 400 moves relative to the housing 100 so that the second seal 400 is misaligned with the corresponding tension adjustment port 104. In an optional embodiment, the second seal 400 is slidably matched with the housing 100, so that the second seal 400 can slide between the first position and the second position relative to the housing 100.

[0085] In the above example, the second sealing member 400 can seal the tightness adjustment port 104 to ensure the sealing performance of the wiring sealing chamber 101. Therefore, this embodiment can not only improve the connection reliability between the cable and the terminal 200, but also help ensure the sealing performance of the wiring sealing chamber 101.

[0086] In some optional embodiments, at least part of the portion of the cable inserted into the wiring sealed cavity 101 needs to be stripped, that is, the insulation layer of one end of the cable inserted into the wiring sealed cavity 101 needs to be removed to achieve electrical connection between the cable and the wiring terminal 200 .

[0087] Reference Fig. 9 In some optional embodiments, the housing 100 has a stripping comparison mark 150. For example, the operator can judge whether the stripping length of the cable is compatible with the terminal 200 of the electronic circuit breaker according to the stripping comparison mark 150 to ensure the reliability of the electrical connection between the cable and the terminal 200. In addition, it is also beneficial to prevent the stripping length from being too long, resulting in the partial metal core of the cable being exposed. For example, the stripping comparison mark 150 can be, but is not limited to, a scale line, a groove and / or a protrusion provided on the housing 100.

[0088] In some optional embodiments, the second sealing member 400 includes a sealing portion 410 and a connecting portion 420. The sealing portion 410 is configured to seal the tension adjustment port 104, and the sealing portion 410 is detachably connected to the housing 100 so that the sealing portion 410 can be separated from the housing 100. Exemplarily, in the case where it is necessary to tighten or remove the cable and the terminal 200, the sealing portion 410 is first detached from the housing 100. Then, the tension adjustment port 104 is used to provide an operating space for tightening or removing the cable and the terminal 200. In the case where it is not necessary to tighten or remove the cable and the terminal 200, the sealing portion 410 is assembled with the housing 100 so that the sealing portion 410 seals the tension adjustment port 104.

[0089] In some optional embodiments, the connection part 420 is respectively connected to the connection part 420 and the housing 100. In the case where the sealing part 410 is separated from the housing 100, the sealing part 410 can be connected to the housing 100 through the connection part 420, which is beneficial to prevent the sealing part 410 from being lost.

[0090] Reference Figure 1 In some optional embodiments, the connection part 420 may be a rope. Specifically, one end of the connection part 420 is connected to the housing 100, and the other end is connected to the sealing part 410. Figure 1 The housing 100 and the sealing portion 410 are both provided with connection holes, so that the housing 100 and the sealing portion 410 can be connected to the connection portion 420 through the connection holes. In some optional embodiments, the connection portion 420 and the sealing portion 410 are an integrated structure.

[0091] Reference Fig. 9 and Fig.10 In some optional embodiments, the connection part 420 can be a cover body hinged to the housing 100. Exemplarily, the first end of the connection part 420 is rotatably connected to the housing 100, and the second end of the connection part 420 is detachably connected to the housing 100. In this way, not only can the sealing part 410 be connected to the housing 100 through the connection part 420, but also pressure can be provided to the sealing part 410 when the sealing part 410 seals the tightness adjustment port 104, so as to improve the sealing performance between the sealing part 410 and the housing 100. In some further optional embodiments, the second end of the connection part 420 can be detachably connected to the housing 100 by, but not limited to, screws or buckles.

[0092] According to some optional embodiments, referring to Fig. 9The housing 100 has a second sealing protrusion 140. The second sealing protrusion 140 surrounds the tension adjustment port 104. When the second sealing member 400 seals the tension adjustment port 104, the second sealing protrusion 140 stops at the second sealing member 400. Exemplarily, when the second sealing member 400 seals the tension adjustment port 104, the second sealing member 400 can be pressed against the second sealing protrusion 140 under the pressure of the connecting portion 420, so that the second sealing member 400 and the second sealing protrusion 140 stop part are sunken, which is beneficial to improve the reliability of the second sealing member 400 sealing the tension adjustment port 104.

[0093] According to some optional embodiments, the electronic circuit breaker further includes a mounting member 800 and an elastic member. The housing 100 is provided with a first mounting seat 170 and a second mounting seat 180 spaced apart from the first mounting seat 170, and a buckle groove 105 is formed between the first mounting seat 170 and the second mounting seat 180. Exemplarily, the first mounting seat 170 and the second mounting seat 180 are located at the bottom of the housing 100. During the installation of the electronic circuit breaker, the first mounting seat 170 and the second mounting seat 180 can be buckled with the fixing seat through the buckle groove 105 formed between the first mounting seat 170 and the second mounting seat 180. The fixing seat can be, but is not limited to, a fixing bracket or a fixing table for installing the electronic circuit breaker.

[0094] In some optional embodiments, at least one of the first mounting seat 170 and the second mounting seat 180 has a mounting member 800 and an elastic member, and the elastic member can drive the end of the mounting member 800 adjacent to the buckle groove 105 to at least partially protrude into the buckle groove 105 to buckle with the fixed seat. In this embodiment, the width of the buckle groove 105 can be adjusted by the size of the portion of the mounting member 800 protruding into the buckle groove 105 to adapt to fixed seats of different sizes. On the other hand, since the mounting member 800 can move relative to the first mounting seat 170 or the second mounting seat 180. In this way, in the process of buckling the electronic circuit breaker to the fixed seat, it is not necessary to slide from the end of the fixed seat to a preset position. Specifically, the width of the buckle groove 105 can be adjusted by sliding the mounting member 800 relative to the first mounting seat 170 or the second mounting seat 180, and after the electronic circuit breaker is buckled on the fixed seat, the mounting member 800 can be driven by the elastic member so that the mounting member 800 is buckled with the fixed seat.

[0095] In some optional embodiments, the mounting member 800 has a mounting hole at one end away from the buckle groove 105. Specifically, in the absence of a fixing seat, the electronic circuit breaker can be installed at a preset position using the first mounting and screws. Specifically, the screw passes through the mounting hole and is connected to the component used to install the electronic circuit breaker to achieve fixed installation of the electronic circuit breaker. The mounting hole is provided at one end of the mounting member 800 away from the buckle groove 105, so that the position of the mounting hole can be adjusted by moving the mounting member 800 to adapt to components with different mounting hole distances. In some optional embodiments, the first mounting seat 170 and the second mounting seat 180 are both provided with a mounting member 800 and an elastic member. This is beneficial for making the electronic circuit breaker adapt to fixing seats of more sizes.

[0096] In addition, in the above embodiment, the electronic circuit breaker component can be adapted to a fixing base fixed by snap-fitting, and can also be adapted to a fixing base fastened by screws, thereby making the electronic circuit breaker applicable to fixing bases of more types and sizes, thereby improving the convenience of installing the electronic circuit breaker.

[0097] In summary, the electronic circuit breakers provided in some embodiments of the present application have good waterproof performance and can cope with outdoor application scenarios of smart street lamps. In addition, the electronic circuit breakers in some embodiments are simple and convenient to connect, support multi-way incoming or outgoing line connection, and also have excellent waterproof performance and high reliability.
