Description

TECHNICAL FIELD

[0001] The utility model relates to electrical equipment technical field, especially a kind of relay and power distributor. BACKGROUND

[0002] In the prior art charging pile field, there are mainly two schemes for the technical implementation of the power distribution device. The first scheme adopts a high-voltage DC contactor installed by screws, and the power distribution of the power module is realized by a high-voltage contactor. The contactor is integrated in a cabinet and fixed by copper bar combination and screws, resulting in a large system size and increased cost. The second scheme uses a low-voltage DC relay integrated on a PCB. The relay and copper bars are integrated by PCBA processing technology to replace the high-cost contactor with a low-cost relay, effectively reducing the cost. However, the PCBA production process is complex and involves plug-in, reflow soldering, wave soldering, and other processes. If self-produced, it requires high equipment investment.

[0036] The utility model provides a kind of relay.

[0037] In the embodiment, referring to Figure 5 And Figure 6 Relay 20 includes a housing, at least one set of main lead-out pins 21 and at least one set of main contact assemblies, the main lead-out pins 21 are arranged on the outer wall of the housing, and the main contact assemblies are arranged in the interior of the housing; the main lead-out pins 21 are connected with the main contact assemblies, and the main lead-out pins 21 are used for connecting the circuit; the main lead-out pins 21 include first lead-out pins 211 and second lead-out pins 212, the direction from the interior of the housing to the outer wall of the housing is defined as the first direction, the length of the first lead-out pins 211 along the first direction is greater than the length of the second lead-out pins 212 along the first direction; and the first lead-out pins 211 and the second lead-out pins 212 extend horizontally towards two face positions respectively, or the first lead-out pins 211 and the second lead-out pins 212 extend horizontally along the same face position.

[0038] By making the length of the first lead-out leg 211 greater than the length of the second lead-out leg 212; this length difference design allows the relay 20 to have more flexibility during installation. The longer first and second lead-out legs 211, 212 can be more easily connected to the corresponding conductive input terminals, especially in cases where space is limited or the conductive terminal positions are not easily accessible. The longer lead-out legs provide additional contact range, reducing the need for precise alignment, thus simplifying the installation process and reducing the likelihood of installation errors. The longer input lead-out legs can better accommodate installation deviations, ensuring reliable connection with the conductive input terminals and reducing the risk of poor contact. The length difference design allows for more efficient wiring in limited space, optimizing the overall space utilization of the power distributor.

[0039] In the first configuration, the first and second lead-out legs 211, 212 extend horizontally towards two different face positions. This layout allows the relay 20 to be connected to the circuit from different directions in cases where space is limited, providing greater flexibility and adaptability. For example, the first lead-out leg 211 can extend from one side of the relay 20, while the second lead-out leg 212 extends from the opposite side, allowing efficient wiring in a compact space.

[0040] In the second configuration, the first and second lead-out legs 211, 212 extend horizontally along the same face position. This layout is suitable for applications that require wiring in the same plane or direction. In this way, the wiring process can be simplified, reducing the complexity of wiring, and also facilitating maintenance and inspection.

[0041] The utility model discloses a set of main lead-out legs 21 and a set of main contact assemblies are arranged in the relay 20, and the main lead-out legs 21 are arranged on the outer wall of the shell, and the main contact assemblies are arranged in the shell. The main lead-out legs 21 are connected with the main contact assemblies and are used for connecting the circuit. The main lead-out legs 21 include the first lead-out leg 211 and the second lead-out leg 212, the length of the first lead-out leg 211 along the direction from the inside of the shell to the outer wall is greater than that of the second lead-out leg 212, and the first lead-out leg 211 and the second lead-out leg 212 extend horizontally towards two different face positions or extend horizontally along the same face position. In this way, the relay 20 has greater flexibility during installation, the longer first lead-out leg 211 provides additional contact range, optimizes the overall space utilization of the power distributor, reduces the volume of the power distributor using the relay 20, and the length difference between the first lead-out leg 211 and the second lead-out leg 212 facilitates the detachable connection of the first lead-out leg 211 and the second lead-out leg 212 with the conductive input terminals and the conductive output terminals, avoids the use of a PCB, and thus reduces the difficulty of heat dissipation.

[0042] In an embodiment, with reference to Figure 5 and Figure 6, the two adjacent surfaces of the housing are a first mounting surface and a second mounting surface, the first lead-out pin 211 is arranged on the first mounting surface, and the second lead-out pin 212 is arranged on the second mounting surface.

[0043] The first mounting surface is a side surface of the housing of the relay 20, and the second mounting surface is a top surface of the housing of the relay 20, the first lead-out pin 211 is arranged on the first mounting surface, and the second lead-out pin 212 is arranged on the second mounting surface.

[0044] This sub-surface layout by distributing the lead-out pins on different surfaces can reduce mutual interference between the lead-out pins, improve electrical performance, allow more direction selection of the relay 20 during installation to adapt to different circuit board layouts and space limitations. In addition, this design also helps to simplify wiring, making the connection of the relay 20 clearer and more orderly.

[0045] The sub-surface layout of the lead-out pins makes the wiring clearer and more orderly, reduces the complexity and error rate of wiring, and also facilitates maintenance and inspection.

[0046] In an embodiment, referring to Figure 5 and Figure 6 , the first lead-out pin 211 and the second lead-out pin 212 are arranged close to the same side edge of the first mounting surface and the second mounting surface.

[0047] Arranging the lead-out pins close to the same side edge not only helps to simplify wiring, making the connection of the relay 20 clearer and more orderly, making the structure of the relay 20 regular, reducing the volume of the relay 20, but also the layout of the lead-out pins close to the same side edge makes the wiring clearer and more orderly, reduces the complexity and error rate of wiring, this layout reduces the mutual interference between the lead-out pins, helps to reduce the space occupied by the relay 20, improves the space utilization rate, thereby facilitating the assembly of the relay 20 with the conductive terminals of the power distributor.

[0048] In an embodiment, referring to Figure 5 and Figure 6 , the first lead-out pin 211 includes a first connecting portion 211a and a first lead-out portion 211b, the first connecting portion 211a is arranged on the first mounting surface, and the first lead-out portion 211b is connected to one end of the first connecting portion 211a away from the first mounting surface; the second lead-out pin 212 includes a second connecting portion 212a and a second lead-out portion 212b, the second connecting portion 212a is connected to the second mounting surface, and the second lead-out portion 212b is connected to one end of the second connecting portion 212a away from the second mounting surface; the first lead-out portion 211b and the second lead-out portion 212b extend horizontally along the same surface, or the first lead-out pin 211 and the second lead-out portion 212b extend horizontally along different surfaces.

[0049] The first lead-out leg 211 is divided into a first connecting portion 211a and a first lead-out portion 211b. This design allows the first lead-out leg 211 to have a stable connection point on the first mounting surface and achieve connection with external circuits through the first lead-out portion 211b. Similarly, the second lead-out leg 212 includes a second connecting portion 212a and a second lead-out portion 212b. The second connecting portion 212a is connected to the second mounting surface, and the second lead-out portion 212b is connected to the end of the second connecting portion 212a away from the second mounting surface. This design provides a stable connection point for the second lead-out leg 212 and achieves connection with external circuits through the second lead-out portion 212b.

[0050] The first lead-out portion 211b and the second lead-out portion 212b extend horizontally along the same plane, or the first lead-out leg 211 and the second lead-out portion 212b extend horizontally along different planes. This layout provides two different installation and wiring options to adapt to different application scenarios and installation requirements. When the first lead-out portion 211b and the second lead-out portion 212b extend horizontally along the same plane, the wiring process can be simplified, making the connection of the relay 20 more clear and orderly. This layout reduces the mutual interference between the lead-out legs, improving electrical performance. When the first lead-out leg 211 and the second lead-out portion 212b extend horizontally along different planes, greater flexibility and adaptability are provided, allowing the relay 20 to be connected to the circuit from different directions in a space-limited situation.

[0051] In an embodiment, referring to Figure 5 and Figure 6 , the first lead-out portion 211b is provided with a first mounting hole 211c, and the second lead-out portion 212b is provided with a second mounting hole 212c. The first mounting hole 211c is used for detachable connection with the first conductive input end 3 of the power distributor, and the second mounting hole 212c is used for detachable connection with the second conductive output end 6 of the power distributor.

[0052] The first lead-out portion 211b is provided with a first mounting hole 211c for detachable connection with the first conductive input end 3 of the power distributor. This design allows the first lead-out leg 211 to have a stable connection point on the first mounting surface and achieve flexible connection with external circuits through the first mounting hole 211c.

[0053] The second lead-out portion 212b is provided with a second mounting hole 212c for detachable connection with the second conductive output end 6 of the power distributor. This design provides a stable connection point for the second lead-out leg 212 and achieves connection with external circuits through the second mounting hole 212c.

[0054] The design of the first mounting hole 211c and the second mounting hole 212c allows the relay 20 to achieve detachable connection with the conductive terminals of the power distributor. This detachable connection not only improves the convenience of installation and maintenance, but also enhances the flexibility and adaptability of the system. Through these mounting holes, the relay 20 can be easily connected to the corresponding terminals of the power distributor without the need for complex welding or fixing processes. The design of the mounting holes makes the installation and removal process of the relay 20 more simple, reduces maintenance costs and time, and improves the reliability and continuous operation capability of the system.

[0055] In an embodiment, referring to Figure 5 and Figure 6 , the relay 20 includes two groups of main lead-out pins 21 and two groups of main contact assemblies, each main lead-out pin 21 being connected with a main contact assembly; the two main lead-out pins 21 are arranged on the two sides of the shell in a spaced manner.

[0056] The two main lead-out pins 21 are arranged on the two sides of the shell in a spaced manner. This layout not only helps to simplify the wiring and make the connection of the relay 20 more clear and orderly, but also helps to reduce the mutual interference between the lead-out pins and improve the electrical performance. The spaced main lead-out pins 21 can effectively disperse heat and reduce temperature rise, improving the thermal stability of the relay 20.

[0057] The connection design of the main lead-out pin 21 and the main contact assembly takes into account electrical isolation and mechanical stability. By directly connecting the lead-out pin with the contact assembly, the resistance and power loss during current transmission can be reduced, improving energy transmission efficiency. In addition, this connection method also helps to simplify the internal structure of the relay 20 and reduce manufacturing costs.

[0058] The utility model also proposes a kind of power distributor.

[0059] Please refer to Figures 1 to 5 , in the utility model embodiment, the power distributor includes mounting plate 1, multiple groups of relay assemblies 2, multiple first conductive input terminals 3 and multiple first conductive output terminals 4;Each group of relay assembly 2 includes multiple relays 20, and multiple relays 20 are detachably connected to mounting plate 1;Multiple first conductive input terminals 3 are detachably connected to mounting plate 1, and each first conductive input terminal 3 is detachably connected with multiple relays 20 in the same group of relay assembly 2;Multiple first conductive output terminals 4 are detachably connected to mounting plate 1, each first conductive output terminal 4 is arranged in a spaced manner with multiple first conductive input terminals 3;And each first conductive output terminal 4 is detachably connected with a relay 20 of multiple groups of relay assemblies 2.

[0060] The first lead-out pin 211 of the relay 20 is detachably connected with the first conductive input end 3, and the second lead-out pin 212 is detachably connected with the first conductive output end 4. The mounting plate 1 is the skeleton of the power distributor, which is made of a solid insulating material to ensure safety under high voltage and large current working conditions. The design of the mounting plate 1 allows detachable connection of multiple groups of relay assemblies 2, first conductive input ends 3 and first conductive output ends 4, providing a stable and flexible platform. The relay assembly 2 is the core part of the power distributor, and each group of relay assembly 2 contains multiple relays 20. These relays 20 adopt a modular design, which can be quickly disassembled and replaced, thereby reducing maintenance cost and time. The bistable magnetic holding structure of the relay 20 and the unique lead-out terminal design are beneficial to the connection layout of the copper bar and good heat dissipation capacity. The first conductive input end 3 is responsible for leading the external power into the power distributor and connecting with the relays 20 in the relay assembly 2. These input ends adopt a detachable design, which is convenient for installation and maintenance. Each input end is detachably connected with the relays 20 in the same group of relay assembly 2, providing a flexible power input path. The first conductive output end 4 is responsible for transmitting the power controlled by the relay assembly 2 to the load. These output ends are arranged at intervals with the input ends, ensuring electrical isolation and improving the safety of the system.

[0061] The external power is connected into the power distributor through the first conductive input end 3, and the input end is connected with the relays 20 in the relay assembly 2, ensuring smooth transmission of current. The relays 20 control the on-off of current according to the control signal, realizing the distribution and control of power.

[0064] The first lead-out pins 211 of the plurality of relays 20 in the same group of relay assemblies 2 are detachably connected to the same first conductive input terminal 3. The second lead-out pins 212 of each relay 20 in the same group of relay assemblies 2 are detachably connected to a first conductive output terminal 4. The mounting plate 1 has a first side extending in the transverse direction, which has a suitable length to meet the installation and fixing requirements; at the same time, the mounting plate 1 also has a second side extending in the vertical direction, which has a suitable height to adapt to different use scenarios. On the mounting plate 1, a plurality of groups of relay assemblies 2 are arranged in a spaced manner along the second side, forming an orderly assembly array.

[0065] Specifically, the plurality of relays 20 in the same group of relay assemblies 2 are arranged in a spaced manner along the first side, so that appropriate distances are maintained between the relays 20 to ensure the stability and reliability of electrical connection. In addition, the mounting plate 1 is also provided with a plurality of first conductive input terminals 3, which are arranged in a spaced manner along the second side to facilitate connection with external power sources or other circuits. At the same time, the mounting plate 1 is also provided with a plurality of first conductive output terminals 4, which are arranged in a spaced manner along the first side to facilitate the transmission of signals output by the relays 20 to other circuits or devices. The mounting plate 1 has a first side extending in the transverse direction and a second side extending in the vertical direction; a plurality of groups of relay assemblies 2 are arranged in a spaced manner along the second side, and the plurality of relays 20 in the same group of relay assemblies 2 are arranged in a spaced manner along the first side; a plurality of first conductive input terminals 3 are arranged in a spaced manner along the second side; and a plurality of first conductive output terminals 4 are arranged in a spaced manner along the first side.

[0066] The transverse and vertical design of the mounting plate 1 enables the relay assemblies 2 and conductive terminals to make efficient use of space, improving the compactness and installation efficiency of the power distributor, and facilitating integration into devices with limited space. The relays 20 are arranged in a spaced manner in the transverse direction, simplifying wiring and making maintenance work more convenient and reducing maintenance costs. When replacing or repairing the relays 20, they can be quickly located and operated without the need to disassemble the entire system. The spaced arrangement of the relay assemblies 2 and conductive terminals enhances electrical isolation, reduces the risk of short circuits and overloads, and improves the safety of the system.

[0067] The arrangement of the relays 20 in the transverse direction enables more uniform current distribution, improving the efficiency of power distribution and the response speed of the load. This uniform current distribution helps to improve the efficiency of the entire system and reduce energy loss.

This arrangement facilitates even distribution of power and easy access to the input terminals. A plurality of first conductive output terminals 4 are arranged along the first side of the mounting plate 1, below the first conductive input terminals 3. This design helps to reduce the length of the wires, thereby reducing the resistance and power loss, and also facilitates wiring and maintenance.

[0070] The first conductive output terminals 4 are arranged below the first conductive input terminals 3. This vertical layout helps to simplify wiring, reduce wiring confusion, and lower the possibility of wiring errors, while also facilitating later line inspection and maintenance.

This design provides additional flexibility, allowing the power distributor to configure more input paths as needed.

This arrangement helps to evenly distribute the power supply and easily access the input terminals.

Similarly, the second conductive output 6 is arranged in parallel with the first conductive output 4, and arranged in a staggered manner along the direction of the first side. This staggered arrangement provides additional flexibility, allowing the second group of terminals to be accessed and configured without interfering with the first group of terminals, thereby improving the adaptability and expandability of the power distributor.

[0080] By staggered arrangement, more conductive terminals can be integrated in limited space, providing additional connection paths, so that the power distributor can adapt to more complex application scenarios, improving the flexibility and scalability of the system. Further allowing the power distributor to be configured according to actual needs, whether increasing input sources or output loads, it can easily cope with, thereby improving the space utilization of the mounting plate 1, making the power distributor more compact, suitable for space-limited application scenarios.

[0081] In addition, staggered arrangement helps air circulation, improves heat dissipation conditions, especially in high power density applications, good heat dissipation design can significantly improve the stability and life of the system.

[0083] In this embodiment, the first conductive input terminal 3 and the first conductive output terminal 4 are located on both sides of the relay 20, while the second conductive input terminal 5 and the second conductive output terminal 6 are located between them. By designing the spacing between these terminals and the mounting plate 1 to be sequentially reduced, a more compact layout can be achieved, reducing the overall size while maintaining or improving electrical performance.

[0084] By designing the spacing to be sequentially reduced, the power distributor further optimizes the spacing between the conductive terminals and the mounting plate 1 while maintaining the required electrical clearance, allowing for more compactness, suitable for space-limited application scenarios, improving the space utilization of the mounting plate 1, to achieve more compact and efficient power distribution.

[0085] In an embodiment, referring to Figures 1 to 5 , the mounting plate 1 is an insulating plate; the first conductive input terminal 3, the first conductive output terminal 4, the second conductive input terminal 5 and the second conductive output terminal 6 are copper or aluminum bars.

[0086] The mounting plate 1 is made of insulating material, such an insulating plate not only provides good electrical isolation, preventing accidental short circuits, but also has sufficient mechanical strength to support the relay 20 and the conductive bars. The use of insulating plates ensures the safe operation of the power distributor in various environments, especially in humid or corrosive environments, its performance remains stable.

Copper and aluminum are both excellent conductive materials, with high electrical conductivity and good thermal conductivity, which makes the conductive bars not only able to effectively transmit electrical energy, but also quickly dissipate the heat generated by the current passing through, thereby reducing the temperature rise and improving the thermal stability of the system.
