Description

Technical Field

[0001] The present application relates to the technical field of energy storage products, and particularly to a power connector and an energy storage device. Background Art

[0002] In recent years, household energy storage products have become increasingly popular among consumers, meeting the needs of various power usage scenarios such as work, study, and entertainment for consumers. In terms of the development trend, the power of household energy storage products is getting larger and larger, so as to meet more different power usage needs of consumers. The larger the power means the higher the voltage and current of the household energy storage product. When performing the DC terminal plugging operation, the phenomenon of current breakdown of air to generate arcing and sparking occurs more and more frequently, which causes discomfort to consumers, has certain potential safety hazards, and will reduce the service life of the DC terminal. Summary of the Utility Model

[0003] Based on this, it is necessary to provide a power connector and an energy storage device for the problem of avoiding the phenomenon of current breakdown of air to generate arcing and sparking during plugging.

[0004] In the first aspect of the present application, a power connector is provided, including:

[0005] A female end assembly, the female end assembly includes a female end seat body, a female end terminal assembly, and a female end signal assembly, and the female end terminal assembly and the female end signal assembly are respectively arranged on the female end seat body; and

[0006] A male end assembly, the male end assembly includes a male end seat body, a male end terminal assembly, a male end signal assembly, and a switch assembly, and the male end terminal assembly, the male end signal assembly, and the switch assembly are respectively arranged on the male end seat body;

[0007] Wherein, the switch assembly is electrically connected to the male end signal assembly, the switch assembly is used for being electrically connected to an external controller, and when the controller recognizes that the switch assembly is in the on state, it supplies power to the power connector. The female end assembly is inserted and mated with the male end assembly, the female end signal assembly is in contact and conduction with the male end signal assembly to make the switch assembly in the on state, and the female end terminal assembly is adapted to be connected with the male end terminal assembly along with the contact and conduction of the female end signal assembly and the male end signal assembly.

[0008] When the power connector of this solution is in use, the female end component and the male end component are inserted and assembled together, so that the male end seat body and the female end seat body are inserted and fixed, the male end signal component and the female end signal component are in contact and conduct electricity. At the same time, the male end terminal component and the female end terminal component are also adapted and connected. Since the switch component is electrically connected to the male end signal component and is also electrically connected to an external controller, the switch component is in the on state only when the male end signal component and the female end signal component are in good contact. At this time, the controller will only energize the power connector when it recognizes that the switch component is in the on state. Since the male end terminal component and the female end terminal component have formed contact and connection at this time and there is no gap between them, even if a high-power load current is connected, there will be no phenomenon of current breaking through the air and generating sparking and arcing; in other words, this solution enables the male end component and the female end component to be installed in a non-powered manner. Because the controller will not energize the power connector when it does not recognize that the switch component is in the on state, even if a narrow gap is formed between the male end terminal component and the female end terminal component before they are in contact and conduction during the plugging and assembling process, due to the lack of load current, there will be no phenomenon of current breaking through the air in the gap and generating sparking and arcing; in summary, the power connector of this solution has the ability to prevent sparking and arcing, thus ensuring the comfort and experience of users, increasing the service life of the power connector, and eliminating potential safety hazards.

[0014] During the process of inserting and mating or disassembling the female end assembly and the male end assembly, the hook portion abuts against the abutting portion to squeeze the key to move towards the inside of the receiving cavity, so that the key abuts against the third switch elastic sheet, and the switch assembly is in an off state; when the female end assembly and the male end assembly are inserted and mated completely, the hook portion passes over the abutting portion and is snapped into the clamping hole, the key is separated from contact with the third switch elastic sheet, and the switch assembly is in an on state.

Detailed implementation manners

[0036] To make the above objects, features, and advantages of the present application more obvious and understandable, the following will describe the detailed implementation manners of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0037] In the description of the present application, it should be understood that if there are terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the drawings. These are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation on the present application.

[0038] In addition, if there are terms such as "first" and "second", these terms are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present application, if there is a term "plurality", the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0039] In the present application, unless otherwise clearly specified and limited, if there are terms such as "install", "connect", "join", "fix", etc., these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0040] In the present application, unless otherwise clearly specified and limited, if there is a description such as a first feature being "on" or "under" a second feature, etc., the meaning can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature can mean that the first feature is directly above or obliquely above the second feature, or simply indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or simply indicates that the first feature has a lower horizontal height than the second feature.

[0041] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If present, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are only for illustrative purposes and do not represent the only implementation.

[0042] Referring to Figures 1 to 7 , a power connector 100 shown in an embodiment of the present application includes a female terminal assembly 10 and a male terminal assembly 20. For example, the power connector 100 is applicable to energy storage devices. The female terminal assembly 10 is used for electrically connecting to the main body of the energy storage device, and the male terminal assembly 20 is used for electrically connecting to an external electrical device. By mating the male terminal assembly 20 with the female terminal assembly 10, electrical connection between the electrical device and the main body of the energy storage device can be achieved, enabling the main body of the energy storage device to supply electrical energy to the electrical device. It can be understood that the power connector 100 can also be applicable to servers, large power supply devices, other electronic devices that need to be electrically connected to external devices, etc.

[0043] Exemplarily, the female terminal assembly 10 includes a female terminal housing 11, a female terminal component 12 and a female signal component 13, and the female terminal component 12 and the female signal component 13 are respectively disposed on the female terminal housing 11; the male terminal assembly 20 includes a male terminal housing 21, a male terminal component 22, a male signal component 23 and a switch component 24, and the male terminal component 22, the male signal component 23 and the switch component 24 are respectively disposed on the male terminal housing 21.

[0044] To ensure safety during use and prevent electric shock accidents, both the female terminal housing 11 and the male terminal housing 21 are made of non-conductive materials, such as plastics, etc.

[0045] Among them, the switch component 24 is electrically connected to the male signal component 23. The switch component 24 is used for electrically connecting to an external controller, and when the controller recognizes that the switch component 24 is in the on state, it supplies power to the power connector 100. The female terminal assembly 10 and the male terminal assembly 20 are mated, and the female signal component 13 and the male signal component 23 are in contact and conduct electricity to make the switch component 24 in the on state, and the female terminal component 12 and the male terminal component 22 are adapted to be connected through the contact and conduction of the female signal component 13 and the male signal component 23. The external controller refers to the controller in an external electronic device electrically connected to the power connector 100.

[0046] Optionally, the controller can be, but is not limited to, an MCU, a microcontroller unit (Microcontroller Unit; MCU).

[0047] In summary, implementing the technical solution of this embodiment will have the following beneficial effects: When the power connector 100 of this solution is in use, the female end assembly 10 and the male end assembly 20 are inserted and assembled together, so that the male end seat body 21 is inserted and fixed with the female end seat body 11, the male end signal assembly 23 is in contact and conduction with the female end signal assembly 13. At the same time, the male end terminal assembly 22 and the female end terminal assembly 12 are also adapted and connected. Since the switch assembly 24 is electrically connected to the male end signal assembly 23 and the switch assembly 24 is also electrically connected to an external controller, the switch assembly 24 is in the on state only when the male end signal assembly 23 is in good contact with the female end signal assembly 13. At this time, the controller will only energize the power connector 100 when it recognizes that the switch assembly 24 is in the on state. Since the male end terminal assembly 22 has formed contact and connection with the female end terminal assembly 12 at this time and there is no gap between the two, even if a high-power load current is connected, there will be no phenomenon of current breakdown of air to generate arcing; in other words, this solution enables the male end assembly 20 and the female end assembly 10 to be installed in a non-powered manner, because the controller will not energize the power connector 100 until it recognizes that the switch assembly 24 is in the on state. Therefore, even if a narrow gap is formed between the male end terminal assembly 22 and the female end terminal assembly 12 before they are in contact and conduction during the plugging and assembling process, due to the lack of load current, there will be no phenomenon of current breakdown of the air in the gap to generate arcing; in summary, the power connector 100 of this solution has the ability to prevent arcing, thus ensuring the comfort and experience of users, increasing the service life of the power connector 100, and eliminating potential safety hazards.

[0048] Please continue to refer to Figure 1 , Figure 3 , Figure 6 and Figure 8 , on the basis of the above embodiment, the female end signal assembly 13 includes a first female end signal pin 131 and a second female end signal pin 132, and the first female end signal pin 131 is short-circuited with the second female end signal pin 132; the male end signal assembly 23 includes a first male end signal pin 231 and a second male end signal pin 232, the switch assembly 24 includes a switch key 241 and a shrapnel unit 242, and the shrapnel unit 242 includes a first switch shrapnel 242a, a second switch shrapnel 242b, and a third switch shrapnel 242c. The first switch shrapnel 242a is connected to the second switch shrapnel 242b, and the second switch shrapnel 242b is connected to the third switch shrapnel 242c. Specifically, in this embodiment, the second switch shrapnel 242b and the first switch shrapnel 242a are of an integral structure, and the second switch shrapnel 242b is arranged in a spaced and stacked manner above the first switch shrapnel 242a, so that the two have a certain elastic deformation ability under the pressure state.

[0049] The third switch elastic piece 242c is connected to the side of the second switch elastic piece 242b away from the first switch elastic piece 242a, and the third switch elastic piece 242c and the second switch elastic piece 242b are of an integral structure. In the initial state, the third switch elastic piece 242c is inclined and warped in the direction away from the second switch elastic piece 242b (that is, in the direction of the power switch 241), so that it is easier to contact the descending power switch 241.

[0050] The first switch elastic piece 242a has a first extension arm, and the second switch elastic piece 242b has a second extension arm.

[0051] One end of the first male terminal signal pin 231 is in contact conduction with the first female terminal signal pin 131, and the other end of the first male terminal signal pin 231 is short-circuited to the first switch elastic piece 242a, specifically short-circuited to the first extension arm. The connection method can be welding or others. One end of the second male terminal signal pin 232 is in contact conduction with the second female terminal signal pin 132, and the other end of the second male terminal signal pin 232 is short-circuited to the second switch elastic piece 242b, specifically short-circuited to the second extension arm. The connection method can be welding or others.

[0052] When the power switch 241 is in contact and cooperation with the third switch elastic piece 242c, the switch assembly 24 is in the off state; when the power switch 241 is not in contact and cooperation with the third switch elastic piece 242c, the switch assembly 24 is in the on state. Whether the male terminal assembly 20 and the female terminal assembly 10 are plugged together or pulled apart and disassembled, when pressure is applied to the power switch 241, the power switch 241 can contact the third switch elastic piece 242c and the switch assembly 24 enters the off state, so as to ensure that no load current is connected to the power connector 100, and further avoid the phenomenon of sparking and arcing when the male terminal sub-assembly 22 and the female terminal sub-assembly 12 are connected or separated.

[0053] It is easy to understand that the first female terminal signal pin 131 is short-circuited to the second female terminal signal pin 132; the other end of the first male terminal signal pin 231 is short-circuited to the first switch elastic piece 242a, and the other end of the second male terminal signal pin 232 is short-circuited to the second switch elastic piece 242b; so that the switch assembly 24 is in series with the male terminal signal assembly 23 and the female terminal signal assembly 13, and further the on-off state of the switch assembly 24 can be detected and recognized by the controller.

[0054] Please continue to refer to Figure 1 , Figure 3 and Figure 4, Further, in one embodiment, the female terminal housing 11 is provided with a card hole 111, and the female terminal housing 11 is further provided with an abutting portion 112 arranged adjacent to the card hole 111. The male terminal housing 21 is provided with a receiving cavity 211, a first opening 212 and a second opening 213. The elastic piece unit 242 is arranged in the receiving cavity 211. The switch key 241 includes a button 241a and a hook 241b connected to each other. The button 241a is movably inserted through the first opening 212 and arranged above the elastic piece unit 242. The hook 241b is movably inserted through the second opening 213, and the hook 241b includes a hook portion 2411b extending out of the male terminal housing 21 through the second opening 213.

[0055] During the process of inserting and mating or disassembling the female terminal assembly 10 and the male terminal assembly 20, the hook portion 2411b abuts against the abutting portion 112 to squeeze the button 241a to move towards the inside of the receiving cavity 211, so that the button 241a abuts against the third switch elastic piece 242c, and the switch assembly 24 is in the off state; when the female terminal assembly 10 and the male terminal assembly 20 are inserted and mated completely, the hook portion 2411b passes over the abutting portion 112 and snaps into the card hole 111, the button 241a is separated from the third switch elastic piece 242c, and the switch assembly 24 is in the on state.

[0056] When the male terminal assembly 20 is inserted and mated with the female terminal assembly 10, when the male terminal housing 21 is pushed towards the female terminal housing 11, the hook portion 2411b of the hook 241b will retract and avoid towards the inside of the second opening 213 due to the blocking of the abutting portion 112, so that the hook portion 2411b can slide along the bottom surface of the abutting portion 112 and finally pass over the abutting portion 112. During this process, the hook 241b is squeezed by the abutting portion 112 to cause the button 241a to move downward towards the depth of the receiving cavity 211, so that the button 241a can abut against the third switch elastic piece 242c, ensuring that the switch assembly 24 is in the off state. Only when the hook portion 2411b completely passes over the abutting portion 112 and snaps into the card hole 111, the pressing force on the button 241a disappears, so that the button 241a can float and move to reset, so that the button 241a is separated from the third switch elastic piece 242c, and the switch assembly 24 is switched from the off state to the on state. With the pressing cooperation between the hook portion 2411b and the abutting portion 112, it is not necessary to manually press the button 241a, so as to improve the operation convenience.

[0057] In addition, by means of the hook 241b being clamped in the card hole 111, the male terminal assembly 20 and the female terminal assembly 10 can also be clamped and fixed together to prevent the two from loosening and separating.

[0058] Furthermore, in order to enable the hook portion 2411b to be inserted into the card hole 111, or the button 241a to automatically float and move to reset after the male end assembly 20 and the female end assembly 10 are disassembled and separated, in one embodiment, the male end assembly 20 further includes an elastic component 25, and the elastic component 25 abuts between the button 241a and the side wall of the accommodating cavity 211. The elastic component 25 can apply an elastic thrust to the button 241a to meet the need for the button 241a to automatically float and move to separate from the third switch spring 242c.

[0059] See also Figure 7 In another embodiment, the male end assembly 20 further includes an elastic assembly 25, which includes a plurality of elastic members 251. A plurality of positioning posts 2411b are convexly provided on the side of the button 241a facing the spring unit 242. One end of each elastic member 251 is sleeved with one of the positioning posts 2411b in a one-to-one correspondence, and the other end of each elastic member 251 abuts against the side wall of the accommodating cavity 211. For example, three elastic members 251 are provided, and three positioning posts 2411b are also provided. The positioning posts 2411b are used to install and position the elastic members 251. The three elastic members 251 distributed in a triangular shape can apply a uniform elastic support force to the button 241a to ensure that the button 241a moves smoothly in the first opening 212 without causing the button 241a to tilt and cause movement obstruction.

[0060] In order to facilitate the button 241a to form a conflict with the third switch spring 242c after the button 241a moves downward, so that the switch assembly 24 enters the disconnected state, in one embodiment, the button 241a is further provided with a pressing column 2411a on the side facing the spring unit 242, and the third switch spring 242c is provided with a convex bump 2421c, and the pressing column 2411a can be in conflict with the convex bump 2421c. The pressing column 2411a has a certain design length, and the convex bump 2421c has a certain height, so that the distance between the pressing column 2411a and the convex bump 2421c can be small in the initial state, and the button 241a only needs to move a short downward stroke to ensure effective conflict with the third switch spring 242c, thereby improving the response speed of the switch assembly 24.

[0061] See also Figure 3 In addition, based on any of the above embodiments, the hook 241b is provided with an inclined surface 2412b, which is inclined in a direction away from the abutting portion 112. On the one hand, the resistance when the inclined surface 2412b contacts the abutting portion 112 is smaller, which can make the male end seat body 21 more labor-saving and smoothly complete the plug-in assembly with the female end seat body 11; on the other hand, the abutting portion 112 slides along the inclined surface 2412b, and the extrusion force applied to the hook portion 2411b is more linear, which makes it easier for the button 241a to move downward as a whole.

[0062] Please continue to refer to Figures 3 to 5 In yet another embodiment, one end of the female base body 11 facing the male base body 21 is recessed to form a plugging groove 113, and one end of the male base body 21 facing the female base body 11 is provided with a plugging portion 214, and the plugging portion 214 can be inserted into the plugging groove 113. During the process of the plugging portion 214 being inserted into the plugging groove 113, the outer peripheral wall of the plugging portion 214 is in sliding fit with the groove wall of the plugging groove 113, and thus can play a guiding role in the plugging and assembling of the male end assembly 20 and the female end assembly 10.

[0063] Specifically, one end of the female terminal assembly 12 and one end of the female signal assembly 13 can both extend into the plugging groove 113. The end portions of the plugging portion 214 are respectively provided with a first through hole 2141 and a second through hole 2142. The first through hole 2141 corresponds to the male terminal assembly 22. One end of the female terminal assembly 12 extending into the plugging groove 113 can pass through the first through hole 2141 and be in contact conduction with the male terminal assembly 22. The second through hole 2142 corresponds to the male signal assembly 23. One end of the female signal assembly 13 extending into the plugging groove 113 can pass through the second through hole 2142 and be in contact conduction with the male signal assembly 23. Under the above guiding action, it can be ensured that the female terminal assembly 12 accurately passes through the first through hole 2141 and is in contact conduction with the male terminal assembly 22, and at the same time, it can be ensured that the female signal assembly 13 accurately passes through the second through hole 2142 and is in contact conduction with the male signal assembly 23, improving the connection effectiveness; in addition, the hole wall of the first through hole 2141 and the hole wall of the second through hole 2142 can also support and position the female terminal assembly 12 and the female signal assembly 13, improving the connection stability between the female terminal assembly 12 and the male terminal assembly 22 and between the female signal assembly 13 and the male signal assembly 23.

[0064] Further, on the basis of the above embodiment, a guiding recess 1131 is recessed on the groove wall of the plugging groove 113, and a guiding protrusion 2143 is protruded on the outer wall of the plugging portion 214. The guiding protrusion 2143 can be accommodated in the guiding recess 1131 when the female end assembly 10 and the male end assembly 20 are plugged and assembled. Specifically, both the guiding recess 1131 and the guiding protrusion 2143 are strip-shaped structures, and the length extension directions of both are consistent with the plugging direction of the male end assembly 20 and the female end assembly 10. During the process of the plugging portion 214 being inserted into the plugging groove 113, the guiding protrusion 2143 synchronously slides along the guiding recess 1131, so as to limit the relative deflection between the male end assembly 20 and the female end assembly 10 and ensure that the hook 241b can be smoothly and accurately inserted into the hole 111.

[0065] In yet another embodiment, the female terminal assembly 12 includes a first female terminal 121 and a second female terminal 122, and the male terminal assembly 22 includes a first male terminal clip 221 and a second male terminal clip 222. The first female terminal 121 is elastically clamped with the first male terminal clip 221, and the second female terminal 122 is elastically clamped with the second male terminal clip 222.

[0066] Taking the first female terminal 121 and the first male terminal clip 221 as an example, the first male terminal clip 221 adopts a structure similar to a U-shaped clip. The end of the first female terminal 121 extends between two elastic pieces of the first male terminal clip 221. On the one hand, with the help of the elastic force, the first male terminal clip 221 can clamp and connect the first female terminal 121 more reliably. On the other hand, the two elastic pieces are respectively in contact with the opposite two side surfaces of the first female terminal 121, increasing the contact area and helping to ensure the stability and reliability of electrical connection and signal transmission.

[0067] In addition to the above, the present application also provides an energy storage device, which includes the power connector 100 described in any of the above embodiments.

[0068] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
