Description

Technical Field

[0001] The present invention relates to the technical field of charging equipment, and in particular to a connector and a power distributor. Background Art

[0002] In recent years, with the encouragement of the construction of new infrastructure and the development of new energy vehicles, the charging equipment of electric vehicles, as an important part, has also been continuously developing and growing. At present, charging devices are divided into DC charging and AC charging. Due to the long charging time of AC, many stations prefer DC charging devices. DC charging devices are divided into single-gun and multi-gun. Single-gun charging is to charge all modules inside the charging device at the same time with one gun, which is very efficient. However, the station needs to add more guns and can only invest in more charging devices, which is expensive. Multi-gun charging devices generally use several contactors in series and parallel to achieve power distribution. This method cannot fully dispatch a single module. Alternatively, array relays are used. This method is more expensive, the wiring is complex, workers are prone to misconnection, and subsequent maintenance is also more complicated.

[0003] With the development of electric vehicles, the demand for electric power switching is increasing. However, the one-pile-to-one-vehicle model results in a waste of resources. Therefore, flexible charging with power distribution has been introduced, which allows the power modules to be switched freely at the charging terminal, maximizing resource utilization. However, current electric power switching mainly adopts a relay stacking design. M power modules output N terminals, which generally requires M×N relay stacks. Relays take up a lot of space, are costly, have complex wiring, and are difficult to repair due to contact adhesion. They also have a high temperature rise and are not easy to expand. Summary of the Invention

[0030] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application.

At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0032] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description.

[0035] Example 1

[0036] like Figure 1-5 As shown, this embodiment provides a connector, including a carrier 1, which is an insulating carrier. A conductive component 2 and an output component 3 are assembled on the carrier 1. The conductive components 2 are divided into two groups, and an input point 21 is formed on each of the two groups of conductive components 2 to directly connect to the input power supply. The two groups of conductive components 2 are insulated from each other and conductively cooperate with each other within the same group of conductive components 2. There is at least one group of output components 3, and each group of output components 3 includes two output members 31. The two output members 31 maintain conductive cooperation with the two groups of conductive components 2, and the two output members 31 can be extended relative to the conductive components 2. When the two output members 31 are extended relative to the conductive components 2, they can connect to the external output channel 6; when the two output members 31 are retracted relative to the conductive components 2, they can disconnect from the external output channel 6. The connector of the present application is directly connected to the input power supply through the input point, and the corresponding circuit can be controlled by simply extending and retracting the output component 3, eliminating the need for the external input channel, simplifying the structure, and reducing the volume.

[0037] The carrier 1 extends in a straight line and is formed with mounting grooves for accommodating the conductive components 2. There are two mounting grooves corresponding to the two groups of conductive components 2. To facilitate processing and installation, the two mounting grooves are symmetrically arranged on one side of the carrier 1. Figure 1 As shown, the mounting groove is a long groove extending along the extension direction of the carrier 1 , and the two mounting grooves are separated by the carrier 1 to achieve insulation matching of the two groups of conductive components 2 .

[0038] As the preferred technical solution of this embodiment, in order to reduce weight and facilitate the installation of other structures, the carrier 1 has a hollow structure and is a square body. Two adjacent corners of the carrier 1 are respectively formed with installation grooves, and the cross-section of the installation groove can be a square groove.

[0039] The conductive components 2 are divided into two groups, and the two groups of conductive components 2 are respectively assembled in two mounting grooves. In this embodiment, the conductive component 2 includes at least two conductive parts 22, one of which is formed with an input point 21, and at least two conductive parts 22 are arranged in the receiving groove at intervals. There is a gap between two adjacent conductive parts 22 to accommodate the output part 31 of the output component 3, and the output part 31 is slidably assembled between the two adjacent conductive parts 22, and the output part 31 maintains contact with the two conductive parts 22 to achieve conductive matching. Preferably, in order to ensure the stable assembly of the conductive component 2, after the conductive parts 22 are arranged in the receiving groove, the fasteners 5 are used to fix the conductive parts 22 in the receiving groove. The fasteners 5 can be selected from but not limited to U-shaped fasteners to simultaneously fasten two conductive parts 22 located in the same axial position. Preferably, in order to avoid complicated wiring, the input point 21 is set on the outer end of the conductive part 22 located at the outermost end.

[0040] The output component 3 is at least one group, and each group of output components 3 includes two output members 31. The two output members 31 are respectively conductively matched with two groups of conductive components 2, that is, in each group of output components 3, one output member 31 is cross-arranged and maintained in contact with at least two conductive members 22 in one group of conductive components 2; the other output member 31 is cross-arranged and maintained in contact with at least two conductive members 22 in another group of conductive components 2.

[0041] As a preferred technical solution of this embodiment, the output member 31 is slidably engaged with the adjacent conductive member 22. Specifically, the output member 31 and the adjacent conductive member 22 are provided with a limiting structure to limit the telescopic range of the output member 31 relative to the adjacent conductive member 22. In this embodiment, limiting protrusions 312 are formed on both sides of the output member 31, and limiting grooves 221 are provided on the two adjacent conductive members 22. When assembled, the two limiting protrusions 312 on the output member 31 extend into the two guide Electronics 22 and slides along the limiting groove 221. The limiting groove 221 is a long groove, which can limit the sliding range of the output member 31 through the limiting structure and prevent the output member 31 from separating from the conductive component 2.

[0042] As a preferred technical solution of this embodiment, the telescopic end of the output member 31 is a spherical end to facilitate contact with the external output channel and prevent damage to the external output channel.

[0043] Driven by the telescopic drive assembly 4, the output assembly 3 extends and retracts relative to the conductive assembly 2. The telescopic drive assembly 4 is arranged corresponding to the output assembly 3, with each group of output assemblies 3 corresponding to a group of telescopic drive assemblies 4. In this embodiment, the telescopic drive assembly 4 includes a driver 41 and a reset member 42. The driver 41 is an electromagnetic driver, mounted on the carrier 1. Two symmetrical magnetic ends extend from the driver 41, corresponding to the two output members 31. When the electromagnetic driver is energized and generates a magnetic force, the two output members 31 are attracted and retracted, disconnecting the electrical connection with the external output channel. When the electromagnetic driver is de-energized and loses its magnetic force, the two output members 31 extend outward under the action of the reset member 42, establishing an electrical connection with the external output channel. More specifically, the end of the output member 31, away from the spherical end 311, is provided with a hole, into which the magnetic end of the electromagnetic driver can extend. The magnetic end is also fitted with a reset member 42. One end of the reset member 42 acts on the carrier 1, and the other end acts on the output member 31. The reset member 42 can be, but is not limited to, a spring.

[0044] As an alternative to the telescopic drive assembly 4, the telescopic drive assembly 4 can also utilize a drive member combined with a screw, which can be one or two. The output member 31 is threadedly engaged with the screw. When the drive member drives the screw to rotate in two directions, the output member 31 can reciprocate along the screw. Gears can be used for transmission between the drive member and the screw.

[0045] like Figure 5 As shown, this embodiment also provides a power distributor, including the above-mentioned connector, input power and output channel 6, the input power is directly connected to the two input points 21 on the connector, and the output channel 6 is arranged on the outside of the connector and is arranged corresponding to the output component 3.

[0046] The output channels 6 are arranged in at least one group, and the number of groups corresponds to the number of output assemblies 3. Each group of output channels 6 includes a positive output copper busbar 61 and a negative output copper busbar 62. These busbars 61 and 62 are arranged on either side of the connector, corresponding to the arrangement of the output assemblies 3. When the output member 31 is extended by the telescopic drive assembly 4, it contacts the corresponding copper busbar, forming an electrical connection.

[0047] As a preferred technical solution of this embodiment, at least two groups of output components 3 and at least two groups of output channels 6 can be provided, thereby achieving a power distribution method with one input and one or more outputs. Furthermore, at least two connectors can be provided, at least two of which can be stacked and arranged. The length of the output channel 6 can be appropriately extended, so that at least two connectors can share the output channel 6, thereby achieving a power distribution method with multiple inputs and multiple outputs.

[0048] Example 2

[0049] like Figure 6-7 As shown, this embodiment is essentially the same as the first embodiment, differing in the configuration of the conductive assembly 2 and the output assembly 3. In this embodiment, the conductive assembly 2 includes a main conductive member 23 and a branch conductive member 24. The main conductive member 23 is assembled integrally into the mounting slot. There is at least one branch conductive member 24, which electrically cooperates with the main conductive member 23. The output member 31 is slidably assembled onto the branch conductive member 24. The input point 21 is located at one end of the main conductive member 23.

[0050] Specifically, at least one support seat 11 extends between the two mounting slots of the carrier 1. All support seats 11 are arranged in parallel, and two branch slots are formed on each support seat 11. The two branch slots are respectively connected to the two mounting slots. Branch conductive members 24 are assembled in the branch slots. The branch conductive members 24 can contact the corresponding main conductive members 23 to achieve conductive coordination. The two output members 31 of the output assembly 3 are slidably assembled on the branch conductive members 24. Preferably, the two output members 31 are telescopic relative to the two vertical surfaces of the support seat 11. Further preferably, the branch slots are perpendicular to the mounting slots. After installation, the branch conductive members 24 are perpendicular to the main conductive members 23.

[0051] The power divider in this embodiment is arranged in the output channels 6 outside the connector, and the positive output copper busbar 61 and the negative output copper busbar 62 are arranged corresponding to the output components 3. In this embodiment, in the same group of output channels 6, the positive output copper busbar 61 and the negative output copper busbar 62 are arranged vertically.

[0052] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in this field without departing from the purpose of the present invention.
