DETAILED DESCRIPTION

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application. The embodiments of the present application are described in detail below in conjunction with the drawings.

[0056] The terms "first", "second", "third" (if any) in the specification and claims of this application and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0057] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions; for example, a process, method, apparatus, product, or display comprising a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or display.

[0058] In the related art, the high-voltage connector may include a plastic shell and a metal terminal. The plastic shell is wrapped around the outside of the metal terminal to insulate and protect the terminal. The terminal may include a positive metal terminal and a negative metal terminal. A temperature sensor is provided on the surface of the positive metal terminal and the surface of the negative metal terminal respectively. The two temperature sensors are respectively screwed on the positive metal terminal and the negative metal terminal. The two temperature sensors are respectively connected to the battery management module through two sets of low-voltage cables. In this way, to monitor the temperature of the positive metal terminal and the negative metal terminal, two temperature sensors need to be configured, and correspondingly, two sets of low-voltage cables also need to be provided, thereby increasing the production cost.

[0059] Based on this, an embodiment of the present application provides a connector, a battery pack and an electrical device. The connector sets a temperature sensing component on a first heat conducting part, and plugs at least two electrical connection terminals into at least two second heat conducting parts one by one, so that the heat of at least two electrical connection terminals is transferred to the first heat conducting part, and then to the temperature sensing component, thereby realizing that one temperature sensing component can detect the temperature of at least two electrical connection terminals at the same time, thereby reducing the cost of the connector.

[0060] The specific implementation of the connector, battery pack and electrical equipment provided in the embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0061] The present application also provides an electrical device, including an electrical device and a battery pack, wherein the battery pack is used to provide electrical energy to the electrical device.

[0062] A battery pack can be used to power electrical devices. A battery pack may include at least two battery cells. Relatively speaking, a single battery cell can only provide a smaller voltage and a shorter battery life. For electrical devices that require a higher voltage, multiple battery cells need to be integrated into a battery pack with a higher voltage and a longer battery life, and then the battery pack is used to power the electrical device.

[0063] For example, the electric device may be a vehicle, the electric device may be an electric motor, and the battery pack may provide electric energy to the electric motor, thereby driving the vehicle through the electric motor. The vehicle may be a pure electric vehicle, an extended-range electric vehicle, a hybrid electric vehicle, etc., and the vehicle may also be any vehicle with a battery pack.

[0064] Reference Figure 1 and Figure 2 As shown, the present application provides a battery pack, which may include a battery cell and a connector, wherein the battery cell is conductively connected to the connector. The connector may be used to connect the battery pack and an electrical device, and the connector may transmit the electrical energy stored in the battery pack to the electrical device, thereby enabling the battery pack to supply power to the electrical device.

[0065] The connector may include a male connector and a female connector, the female connector is conductively connected to the battery cell, the male connector is conductively connected to the electrical device, and after the male connector and the female connector are plugged in, the battery pack and the electrical device can be conductively connected. The connector provided in the embodiment of the present application can be a male connector or a female connector.

[0066] It should be noted that the battery pack may also include a battery management component, and the connector is conductively connected to the battery management component, so that the battery management component manages the current, current and temperature of the battery cell, thereby ensuring the normal operation of the battery pack. The battery management component can also manage the temperature of the connector and cut off the current when the temperature of the connector is too high, thereby protecting the connector.

[0067] Reference Figures 1 to 4 As shown, based on the above embodiments, an embodiment of the present application further provides a connector, which includes a ceramic thermal conductor 100, at least two electrical connection terminals 200 and a temperature sensing component 300, the ceramic thermal conductor 100 includes a first thermal conductor 110 and at least two second thermal conductors 120 connected to each other, the at least two second thermal conductors 120 are located on one side of the first thermal conductor 110 along the first direction, and the at least two second thermal conductors 120 are spaced apart along the second direction.

[0068] At least two electrical connection terminals 200 have different electrical polarities, and the electrical connection terminal 200 may include a first connection portion 210 and a second connection portion 220 connected to each other, and the first connection portion 210 and the second connection portion 220 may be arranged along a first direction, and the first connection portions 210 of at least two electrical connection terminals 200 pass through the first heat conducting portion 110 and are inserted into at least two second heat conducting portions 120 in a one-to-one correspondence, and the first connection portions 210 are in thermal contact with the second heat conducting portions 120. The temperature sensing component 300 includes a detection portion 310, and the detection portion 310 is connected to the first heat conducting portion 110.

[0069] The first direction may refer to the X direction in the drawings, and the second direction may refer to the Y direction in the drawings.

[0070] In this embodiment, the electrical connection terminal 200 is used to transmit current or ground, wherein there may be two electrical connection terminals 200, and the two electrical connection terminals 200 may include a positive electrical connection terminal 200 and a negative electrical connection terminal 200. Alternatively, there may be three electrical connection terminals 200, and the three electrical connection terminals 200 may include a positive electrical connection terminal 200, a negative electrical connection terminal 200, and a neutral electrical connection terminal 200.

[0071] That is to say, in the connector of this embodiment, the electrical connection terminal 200 at least includes a positive electrical connection terminal 200 and a negative electrical connection terminal 200 . On this basis, the electrical connection terminal 200 may also include a neutral electrical connection terminal 200 .

[0072] The temperature sensing component 300 is used to detect the temperature of the electrical connection terminal 200. The temperature sensing component 300 can be conductively connected to the battery management component through a low-voltage cable 320, and then the temperature signal of the temperature sensing component 300 is transmitted to the battery management component. In this way, when the current of the electrical connection terminal 200 is large and causes the temperature of the electrical connection terminal 200 to be too high, the battery management component will cut off the current, and then control the temperature of the electrical connection terminal 200 within a normal range, thereby improving the safety of the connector.

[0073] The ceramic heat conductor 100 is used to be in thermal contact with the electrical connection terminal 200, thereby transferring the temperature of two or three electrical connection terminals 200 to the temperature sensing component 300, so that one temperature sensing component 300 can simultaneously detect the temperature of multiple electrical connection terminals 200, thereby reducing the cost of the connector.

[0074] Specifically, the ceramic heat conducting member 100 includes a first heat conducting portion 110 and two or three second heat conducting portions 120. That is, the number of the second heat conducting portions 120 can be set according to the number of the electrical connection terminals 200. When there are two electrical connection terminals 200, there are also two second heat conducting portions 120. When there are three electrical connection terminals 200, there are also three second heat conducting portions 120. The accompanying drawings of this embodiment illustrate a situation where the connector includes two electrical connection terminals 200 and the ceramic heat conducting member 100 includes two second heat conducting portions 120.

[0075] A plurality of second heat-conducting parts 120 are connected to one side of the first heat-conducting part 110 along the first direction, and the plurality of second heat-conducting parts 120 are arranged at intervals along the second direction. In this way, the plurality of second heat-conducting parts 120 can be used to plug in a plurality of electrical connection terminals 200, and the first connection part 210 of each electrical connection terminal 200 can be in thermal contact with the corresponding second heat-conducting part 120, so that the heat of each electrical connection terminal 200 can be transferred to the corresponding second heat-conducting part 120, and so that the heat of all the second heat-conducting parts 120 can be transferred to the first heat-conducting part 110, and the heat of the first heat-conducting part 110 can be transferred to the detection part 310, so that one detection part 310 can simultaneously detect the temperatures of a plurality of electrical connection terminals 200 by detecting the temperature of the first heat-conducting part 110.

[0076] It should be understood that the first connection part 210 can be directly in contact with the second heat-conducting part 120 so that the first connection part 210 can be in thermal contact with the second heat-conducting part 120, or the first connection part 210 can be indirectly in contact with the second heat-conducting part 120 through a thermally conductive adhesive so that the first connection part 210 can be in thermal contact with the second heat-conducting part 120, and the embodiments of the present application are not limited to this.

[0077] In a specific implementation, the first connection part 210 and the second heat conducting part 120 may be attached together so as to make planar contact between the two, thereby increasing the contact area between the two and improving the heat conduction efficiency between the first connection part 210 and the second heat conducting part 120 .

[0078] It should be noted that the ceramic thermal conductor 100 can be made of a ceramic material, which has good thermal conductivity and insulation properties. In order to ensure the thermal conductivity efficiency of the ceramic thermal conductor 100, a ceramic material with a thermal conductivity greater than or equal to 30W / m·K can be selected. For example, the ceramic thermal conductor 100 can be made of one or more materials selected from silicon nitride, aluminum oxide and polycrystalline diamond ceramics. In this way, the heat of each electrical connection terminal 200 can be effectively transferred to the temperature sensing component 300 through the ceramic thermal conductor 100, thereby improving the accuracy of temperature detection.

[0079] In addition, compared with the related art, since the connector of this embodiment is provided with a ceramic thermal conductor 100, it can simultaneously detect the temperatures of multiple electrical connection terminals 200 through a detection unit 310, without the need to provide a detection unit 310 for each electrical connection terminal 200, and one detection unit 310 only needs to lead out a group of low-voltage cables 320 (including one low-voltage cable 320 for the positive pole and one low-voltage cable 320 for the negative pole). In this way, the number of temperature sensing components 300 can be reduced, thereby reducing the cost of the connector.

[0080] It should be understood that when the connector is a female connector, the first connection portion 210 is used to form a socket so that the male connector is plugged into the socket, and the second connection portion 220 is used to be conductively connected to the high-voltage cable. When the connector is a male connector, the second connection portion 220 is used to form a pin to be plugged into the female connector, and the first connection portion 210 is used to be conductively connected to the high-voltage cable. The drawings of this embodiment illustrate the case where the connector is a female connector.

[0081] The connector provided in the embodiment of the present application includes a ceramic heat conductive member 100, an electrical connection terminal 200 and a temperature sensing component 300. The ceramic heat conductive member 100 includes a first heat conductive portion 110 and a second heat conductive portion 120. The electrical connection terminal 200 includes a first connection portion 210. The temperature sensing component 300 includes a detection portion 310. The second heat conductive portion 120 is provided for one-to-one thermal contact with the first connection portion 210, so that the heat of each first connection portion 210 is transferred to the corresponding second heat conductive portion 120. The first heat conductive portion 110 is provided for connecting the detection portion 310 with each second heat conductive portion 120, so that the heat of each first connection portion 210 is transferred to the first heat conductive portion 110. The detection portion 310 is provided for detecting the temperature of the first heat conductive portion 110, so that one detection portion 310 can detect the temperature of multiple first connection portions 210 at the same time, and so that one detection portion 310 can detect the temperature of multiple electrical connection terminals 200 at the same time, thereby reducing the cost of the connector.

[0082] Reference Figures 5 to 8 As shown, in a possible implementation, the connector also includes a first protective shell 400, the first protective shell 400 has at least two first installation cavities 410, the at least two first installation cavities 410 are arranged at intervals along the second direction, and at least two second heat conducting parts 120 are plugged into the at least two first installation cavities 410 one by one.

[0083] It can be understood that the ceramic heat conducting part 100 is made of ceramic material, so the ceramic heat conducting part 100 is easy to break due to collision. The connector of this embodiment can protect the ceramic heat conducting part 100 by providing a first protective shell 400. That is to say, when the second heat conducting part 120 is plugged into the corresponding first installation cavity 410, the first protective shell 400 can protect the multiple second heat conducting parts 120, thereby preventing the second heat conducting parts 120 from breaking due to external force.

[0084] The first protective shell 400 may be made of plastic material, and the second heat conducting portion 120 may be bonded to the first protective shell 400 .

[0085] Reference Figure 2 and Figure 3 As shown, in a possible implementation, the second heat conducting portion 120 includes two heat conducting walls 121, and the two heat conducting walls 121 are arranged at intervals along the third direction. The first connecting portion 210 includes at least one connecting sheet 211, and the at least one connecting sheet 211 is in heat conducting contact with at least one of the two heat conducting walls 121. The third direction can refer to the Z direction in the figure.

[0086] It should be noted that, when the connector is a male connector, the first connection part 210 may include a connection piece 211, so that the first connection part 210 forms a pin of the male connector to be inserted into the socket of the female connector. At this time, the two opposite sides of the connection piece 211 may both be in thermal contact with the two heat-conducting walls 121 to improve the heat conduction effect between the first connection part 210 and the second heat-conducting part 120, or one side of the connection piece 211 may be in thermal contact with one heat-conducting wall 121, and the other side of the connection piece 211 may not be in thermal contact with the other heat-conducting wall 121.

[0087] When the connector is a female connector, the first connection portion 210 may include two connection pieces 211, which are spaced apart along the third direction, so that a socket is formed in the first connection portion 210 to receive the pin of the male connector. At this time, the two connection pieces 211 are in thermal contact with the two heat-conducting walls 121 respectively, so that the heat of the two connection pieces 211 is respectively conducted to the two heat-conducting walls 121, and then conducted to the detection portion 310 through the first heat-conducting portion 110, so that the detection portion 310 detects the temperature of the first connection portion 210.

[0088] Reference Figure 4 , Fig. 9 and Fig.10 As shown, in some embodiments, a plurality of guide reinforcement ribs 1211 are provided on the side of the heat conducting wall 121 away from the connecting piece 211, the plurality of guide reinforcement ribs 1211 are arranged at intervals along the second direction, and the guide reinforcement ribs 1211 extend along the first direction. The inner cavity wall of the first installation cavity 410 is provided with a plurality of guide grooves 411, and the guide reinforcement ribs 1211 are connected to the guide grooves 411 accordingly.

[0089] It can be understood that the ceramic heat conductive part 100 can be made by sintering ceramic materials. During the process of sintering to form the ceramic heat conductive part 100, since the ceramic heat conductive part 100 is prone to bending and deformation, and the ceramic heat conductive part 100 is prone to breakage due to large stress, a guide reinforcing rib 1211 can be provided on the heat conductive wall 121, and the guide reinforcing rib 1211 is provided on the side of the heat conductive wall 121 away from the connecting piece 211. In this way, the inner wall of the heat conductive wall 121 can be smoothed to better contact closely with the first connecting portion 210, and the guide reinforcing rib 1211 can effectively improve the structural strength of the heat conductive wall 121 to prevent the ceramic heat conductive part 100 from bending, deformation, breakage, etc.

[0090] In addition, when assembling the ceramic heat conductive part 100 and the first protective shell 400, since the heat conductive wall 121 is provided with a guide reinforcement rib 1211, a guide groove 411 is correspondingly provided in the first installation cavity 410. The guide reinforcement rib 1211 can be slidably connected with the guide groove 411, so that the second heat conductive part 120 can be smoothly inserted into the first installation cavity 410, and in the subsequent use process, relative displacement is not easy to occur between the ceramic heat conductive part 100 and the first protective shell 400.

[0091] In a possible implementation, the first connection portion 210 includes two connection sheets 211, and the two connection sheets 211 are spaced apart along the third direction. In the third direction, the second connection portion 220 is located between the two connection sheets 211, and a socket is formed between the two connection sheets 211. The two connection sheets 211 are in thermal contact with the two heat-conducting walls 121 in a one-to-one correspondence.

[0092] With such a configuration, the heat of the two connecting pieces 211 can be transferred to the corresponding heat-conducting walls 121 respectively, and then conducted to the first heat-conducting part 110. The detection part 310 can detect the temperature of each connecting piece 211 by detecting the temperature of the first heat-conducting part 110, and then control the temperature of each electrical connection terminal 200 within the required range.

[0093] Reference Figure 4 As shown, in some embodiments, the second heat conducting portion 120 further includes a finger-proof portion 1212, which is connected to an end of the second heat conducting portion 120 away from the first heat conducting portion 110. In the first direction, the finger-proof portion 1212 exceeds an end of the first connecting portion 210 away from the second connecting portion 220.

[0094] In this way, by providing the anti-finger touch portion 1212 at the end of the second heat conducting portion 120 away from the first heat conducting portion 110, and making the anti-finger touch portion 1212 exceed the end of the first connecting portion 210 away from the second connecting portion 220, the operator's fingers will not touch the first connecting portion 210 when plugging or unplugging the connector, thereby ensuring the operator's safety.

[0095] Reference Fig.11 and Fig.12 As shown, in some embodiments, the thickness T of the heat conductive wall 121 is 1 Meet: 1.5mm≤T 1 ≤2.0mm.

[0096] It is understandable that, since the second connection portion 220 is subjected to a thread preload when being threadedly connected, the thread preload is along the third direction, and thus the first connection portion 210 exerts a force on the heat-conducting wall 121 in contact therewith, and the force is also along the third direction and opposite to the thread preload. Since the ceramic heat-conducting member 100 itself is relatively brittle, in order to prevent the ceramic heat-conducting member 100 from being broken due to the force exerted by the electrical connection terminal 200, it is necessary to make the thickness T of the heat-conducting wall 121 1 At the same time, in order to save materials and reduce the volume of the second heat conducting part 120, the thickness T of the heat conducting wall 121 can be 1 Less than or equal to 2mm.

[0097] For example, the thickness T of the heat-conducting wall 121 is 1 It can be any one of 1.5mm, 1.6mm, 1.8mm, 1.9mm, and 2.0mm, or be within any range of two values.

[0098] Reference Fig.13 As shown, in some embodiments, in the second direction, the extension dimension L of the guide reinforcement rib 1211 satisfies: 2T 1 ≤L≤2.5T 1 Such a configuration can make the guide reinforcing ribs 1211 effectively improve the structural strength of the heat-conducting wall 121 in the second direction, thereby making it less likely for the heat-conducting wall 121 to bend, deform, or break.

[0099] In some embodiments, in the third direction, the extension dimension H of the guide reinforcement rib 1211 satisfies: 1.5T 1 ≤H≤2T 1 Such a configuration can make the guide reinforcing ribs 1211 effectively improve the structural strength of the heat-conducting wall 121 in the third direction, thereby making it less likely for the heat-conducting wall 121 to bend, deform, or break.

[0100] In some embodiments, in the second direction, the distance D between two adjacent guide reinforcement ribs 1211 satisfies: 2.5T 1 ≤D≤3.5T 1 The larger the distance D between two adjacent guide reinforcing ribs 1211 is, the greater the probability that the heat conducting wall 121 will be laterally bent and deformed. Therefore, the distance D between two adjacent guide reinforcing ribs 1211 can be controlled within 2.5T. 1 Up to 3.5T 1 Therefore, the guide reinforcing ribs 1211 effectively improve the anti-deformation ability of the heat-conducting wall 121 in the second direction.

[0101] In addition, the number n of the guide reinforcement ribs 1211 can satisfy: n≤(G-2T 1=L+D) / D, where G is the extension dimension of the heat-conducting wall 121 in the second direction. In this way, sufficient guide reinforcing ribs 1211 can be provided on the heat-conducting wall 121 to improve the structural strength of the heat-conducting wall 121.

[0102] It is understandable that the corners of the guide reinforcement ribs 1211 can be connected using arcs or chamfers to avoid stress concentration in these parts.

[0103] Reference Figure 4 As shown, in a possible implementation, the end of the guide reinforcement rib 1211 away from the second connection part 220 has a guide surface 1211a, and the guide surface 1211a is inclined toward the second connection part 220. In this way, when the guide reinforcement rib 1211 just contacts the guide groove 411, the guide surface 1211a has a guiding function, which is beneficial to the assembly of the second heat conducting part 120 and the first protective shell 400, wherein the inclination angle of the guide surface 1211a relative to the heat conducting wall 121 can be between 40° and 50°.

[0104] Reference Figure 5 As shown, in some embodiments, the first heat-conducting part 110 has a second mounting cavity 111, and the detection part 310 is disposed in the second mounting cavity 111. In this way, the first heat-conducting part 110 can be provided with the second mounting cavity 111 for mounting the detection part 310, and the detection part 310 can be encapsulated in the second mounting cavity 111 by the thermal conductive adhesive, so that the detection part 310 is reliably connected to the first heat-conducting part 110, and the thermal conductive adhesive can improve the heat conduction efficiency between the detection part 310 and the first heat-conducting part 110, and protect the detection part 310.

[0105] In specific configuration, the wall thickness T of the second installation cavity 111 may be 2 The thickness T of the first heat conducting portion 110 3 Satisfaction: T 2 ≥0.5T 3 , so as to avoid setting the second mounting cavity 111 at the edge of the first heat conducting portion 110, which would cause the wall thickness of the second mounting cavity 111 to be thinner, thereby avoiding the first heat conducting portion 110 from being broken when the second mounting cavity 111 is formed, or avoiding the first heat conducting portion 110 from being broken due to vibration during subsequent use.

[0106] Reference Figure 1 , Figure 2 As shown, in a possible implementation, the connector may further include a second protective shell 500, the second protective shell 500 and the first protective shell 400 are arranged along the first direction, the first heat conducting part 110 abuts between the first protective shell 400 and the second protective shell 500, and the first protective shell 400 is connected to the second protective shell 500.

[0107] Among them, the first protective shell 400 and the second protective shell 500 can be threadedly connected. After the first protective shell 400 and the second protective shell 500 are connected, the first heat conducting part 110 can be abutted between the first protective shell 400 and the second protective shell 500, and then the first protective shell 400, the ceramic heat conducting component 100 and the second protective shell 500 can be locked together, thereby preventing the first protective shell 400, the ceramic heat conducting component 100 and the second protective shell 500 from relative displacement.

[0108] Reference Figure 2 As shown, in a possible implementation, the second protective housing 500 has at least two mounting portions 510, and the mounting portions 510 are arranged in a one-to-one correspondence with the second connecting portion 220. The mounting portion 510 has a first connecting hole 511, and the second connecting portion 220 has a second connecting hole 221, and the second connecting hole 221 passes through opposite sides of the second connecting portion 220, and the first connecting hole 511 and the second connecting hole 221 are coaxially arranged.

[0109] Thus, after the first connection hole 511 and the second connection hole 221 are aligned, the second connection part 220, the mounting part 510 and the high-voltage cable can be connected by bolts, thereby achieving conductive connection between the second connection part 220 and the high-voltage cable.

[0110] Reference Figure 2 As shown, in a possible implementation, the connector may further include a seal 600 , which is sleeved on an end of the second connection part 220 facing the first connection part 210 , and the seal 600 abuts between the first heat conducting part 110 and the second connection part 220 .

[0111] In this way, after the first protective shell 400, the ceramic thermal conductor 100, the electrical connection terminal 200 and the seal 600 are assembled, the seal 600 can abut between the first thermal conductive part 110 and the second connection part 220, thereby making the first thermal conductive part 110 and the second connection part 220 relatively fixed, and making the first thermal conductive part 110 and the second connection part 220 act as a soft connection through the seal 600, thereby alleviating the vibration generated when the connector is plugged in and out.

Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
