Description

Technical Field

[0001] The utility model relates to the technical field of electrical switches, in particular to an intelligent electrical switch and a charging pile. Background Art

[0002] An intelligent electrical switch is an automatic switching device that connects or disconnects the main circuit of a motor or load. It uses electromagnetic force to close or open the switch, making it suitable for frequent operation and remote control of high-voltage circuits. It also provides low-voltage release protection. The operating principle of an intelligent electrical switch is to use electromagnetic force in conjunction with spring force to connect and disconnect the contacts. The intelligent electrical switch has two operating states: de-energized and energized. When the attraction coil is energized, the static iron core generates electromagnetic attraction, attracting the armature. The connecting rod connected to the armature drives the contacts, causing the normally closed contacts to open and the contactor to enter the energized state. When the attraction coil is de-energized, the electromagnetic attraction disappears, the armature reopens, closing the normally open contacts. The position spring releases, resetting all contacts and placing the contactor in the de-energized state.

[0027] The present invention provides an intelligent electrical switch 100 .

[0028] See also Figures 1 to 4In one embodiment of the present utility model, the intelligent electrical switch 100 includes: a housing 1 and an electrical connection assembly 2; the housing 1 has a first side wall 11 and a second side wall 12, the first side wall 11 and the second side wall 12 intersecting, the first side wall 11 defining an input port 13, and the second side wall 12 defining an output port 14; the electrical connection assembly 2 is installed in the housing 1, and includes a first copper bar 21 and a second copper bar 22, the first copper bar 21 having an input end 23, the input end 23 passing through the input port 13 and extending out of the first side wall 11; the second copper bar 22 having an output end 24, the output end 24 passing through the output port 14 and extending out of the second side wall 12; the output end 24 defining a connection hole 241 for connecting a flexible wire.

[0029] In this embodiment, the bottom of the housing 1 is formed as a first sidewall 11, and one of the vertical sidewalls of the housing 1 is formed as a second sidewall 12. An input port 13 is defined on the bottom wall of the housing 1, and an output port 14 is defined on the side panel of the housing 1. The input end 23 of the first copper busbar 21 is constructed from a thicker, harder solid copper plate, ensuring that the input end 23 retains its original shape and does not bend under sustained gravitational pressure. While maintaining a minimal size, this ensures that the input end 23 still has sufficient current-carrying capacity, facilitating electrical connection after soldering the circuit board. The output end 24 of the second copper busbar 22 is also constructed from a solid copper plate, but includes a connection hole 241 for flexible wire connection and binding. The shape of this hole can be configured to various sizes and shapes as needed, and can also be configured as a hook-shaped structure open from the side, such as a structure suitable for flexible wire connection. The output terminal 24 can be snapped onto the second side wall 12 to limit its installation position. The portion of the output terminal 24 extending from the second side wall 12 is as large as possible while ensuring electrical isolation between phases. It is provided with a connection hole 241, allowing users to flexibly choose to make electrical connections via flexible wires or other methods. This provides users with a variety of electrical connection methods, adapting to a wider range of wiring methods, and rationally planning wiring paths and component layouts, thereby reducing the difficulty and manufacturing cost of client circuit board design layouts. By providing the input terminal 23 and the output terminal 24, the intelligent electrical switch 100 can achieve electrical connection by connecting the output terminal 24 with the connection hole located on the side via a flexible wire when connection to a solid copper plate is not possible.

[0030] The technical solution of the present invention employs a housing 1 and an electrical connection assembly 2 in an intelligent electrical switch 100. The electrical connection assembly 2 includes a first copper busbar 21 having an input terminal 23 and an input port 13 provided on a first side panel of the housing 1, through which the input terminal 23 can output current. A second copper busbar 22 has an output terminal 24 for connecting to a flexible wire and an output port 14 provided on a second side panel 12 of the housing 1, through which the output terminal 24 for connecting to a flexible wire can output current. The output terminal 24 has a connection hole 241, through which a flexible wire for conducting current can be connected to the intelligent electrical switch 100. By providing the input terminal 23 provided on the first side panel and the output terminal 24 provided on the second side panel, the technical solution of the present invention can realize a variety of different circuit connection methods and accommodate a variety of electrical connection components. This allows the intelligent electrical switch 100 to be connected using a flexible wire through the output terminal 24 provided on the side panel when connection to a solid copper plate is not possible.

[0031] In one embodiment, the housing 1 includes an outer shell 15 and a base 16. The outer shell 15 defines a mounting cavity open toward the base 16. The base 16 covers the open end of the mounting cavity. The base 16 defines an input port 13, and the connection between the base 16 and the outer shell 15 forms an output port 14. The outer shell 15 and the base 16 are detachably connected to facilitate assembly and disassembly of the intelligent electrical switch 100. The outer shell 15 has multiple grooves on one side near the base, and the outer wall of the base 16 is provided with retaining posts that fit into the grooves. When the outer shell 15 and the base 16 are assembled, the retaining posts fit into the grooves one-to-one, leaving a gap between the bottom of the groove and the top of the retaining post, large enough to allow the second output port 24 to pass through. This gap forms the output port 14. The base 16 also has a snap-in interface at the bottom, and a snap-in buckle at the end of the outer shell 15 near the base 16. When the outer shell 15 and the base 16 are assembled, the outer shell 15 is placed onto the base 16 and the snap-in buckle is snapped into the snap-in interface, enabling quick assembly of the outer shell 15 and the base 16.

[0032] Reference Figure 2 、 3 In one embodiment, the outer wall of the housing 15 is provided with a plurality of spaced-apart partitions 151. A receiving slot is formed between any two adjacent partitions 151. Multiple second copper bars 22 are provided, and the output end 24 of each second copper bar 22 is accommodated in a receiving slot. The partitions 151 are made of insulating material and serve to separate each receiving slot and each second copper bar 22. Because the second copper bar 22 extends further out of the housing 1, partitions 151 are used to separate the output ends 24 from each other to prevent them from bending due to external forces and causing adjacent output ends to touch and short-circuit. This allows for electrical isolation of the multiple output ends 24 while maintaining sufficient electrical clearance and creepage distances.

[0033] In one embodiment, a notch 242 is provided at the end of the output terminal 24 proximal to the housing 1, and a slot 161 is provided at the end of the base 16 proximal to the second copper busbar 22 for mounting the second copper busbar 22. When the second copper busbar 22 is mounted in the slot 161, the sidewalls of the slot 161 snap into the notch 242. The notch 242 further constrains the output terminal 24, ensuring that multiple output terminals extend to the same fixed length, thus preventing them from being pulled during daily use and causing excessive extension or retraction. The width of the output terminal 24 is equal to the width of the slot 161. When the output terminal 24 is mounted in the slot 161, the protruding wall of the slot 161 protruding from the upper edge snaps into the notch 242. The sidewalls of the notch 242 abut against the wall of the slot 161, confining the wall of the slot 161 within the notch 242, thereby securing the output terminal 24 within the slot 161.

[0034] In one embodiment, the length of the partition 151 is greater than the length of the output terminal 24 extending from the outer wall. To further prevent adjacent output terminals from touching each other, the length of the partition 151 is set to be a certain distance longer than the length of the output terminal 24, and its width is greater than the thickness of the output terminal 24 to prevent short circuits in the intelligent electrical switch 100 during use.

[0035] Reference Figure 3 、 4 In one embodiment, the base 16 is provided with a support structure 162. The support structure 162 is located on the outer wall of the base 16 at a position corresponding to the slot 161. When the second copper busbar 22 is installed in the slot 161, the support structure 162 abuts against the side of the output terminal 24 closest to the base 16. The support structure 162 is located below the slot 161, that is, below the output terminal 24, to prevent the second output terminal from bending toward the bottom under the action of gravity. The support structure 162 cooperates with the partition 151 to further confine the output terminal within the installation slot.

[0036] In one embodiment, the intelligent electrical switch 100 further includes a mounting base, which is disposed on the base 16 and to which the electrical connection assembly 2 is fixedly mounted. The mounting base is used for electrical connection assemblies 2 having irregular shapes. Since the components of the electrical connection assembly 2 may be at different heights during installation, the mounting base provides support and compression for the higher components, while recesses are provided for the lower components to secure them, thereby maintaining the electrical connection assembly 2 in its original shape and preventing interference with the installation of other electronic components.

[0037] In one embodiment, the electrical connection assembly 2 further includes a third copper bar 25 and a fourth copper bar 26 . The fourth copper bar 26 is connected to the second copper bar 22 . The third copper bar 25 is used to connect or disconnect the fourth copper bar 26 to the first copper bar 21 . In this embodiment, the third copper bar 25 is an element that controls the conduction and disconnection of the circuit. The third copper bar 25 has a preset first position and a second position. The third copper bar 25 can switch between the first position and the second position by sliding; the first position is the conduction position. When the third copper bar 25 is in the first position, the third copper bar 25 can electrically connect the first copper bar 21 and the fourth copper bar 26, so that the first copper bar 21, the second copper bar 22, the third copper bar 25 and the fourth copper bar 26 can be electrically connected and current can pass through; the second position is the disconnection position. When the third copper bar 25 is in the second position, the third copper bar 25 is disconnected from the first copper bar 21 and the fourth copper bar 26, and current cannot pass through. At this time, the intelligent electrical switch 100 is in the off state.

[0038] Reference Figure 3 In one embodiment, a slot is provided at the end of the second copper busbar 22 away from the output terminal 24, and a protrusion is provided at the end of the fourth copper busbar 26 away from the third connector, which matches the slot shape and is inserted into the slot. The provision of the slot and the protrusion that fits the slot allows the second copper busbar 22 and the fourth copper busbar 26 to be detachably connected, facilitating removal and replacement of either component if a malfunction occurs. This also facilitates mass production of electronic components, allowing for mass production of parts of the same specification by simply fitting the protrusion into the socket, improving production and maintenance efficiency.

[0039] The present invention also provides a charging pile, which includes any of the above-mentioned intelligent electrical switches 100. The specific structure of the intelligent electrical switch 100 is similar to the above-mentioned embodiments. Since the present charging pile adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be described in detail here. Among them, the charging pile is used to charge electric vehicles.
