[0002] In the prior art, a mating plug is adapted to be inserted into a conductive terminal for electrical contact with the terminal. In order to be able to insert the mating plug into the conductive terminal, the installation position error between the conductive terminal and the plug should be very small or zero, otherwise the mating plug cannot be inserted into the conductive terminal to achieve electrical connection.

[0071] The following will describe the optional implementation manners of the present utility model with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0073] In the description of the present utility model, the terms "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features.

[0074] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "set" and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, also indirectly connected through an intermediate medium, and can also be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0075] As Figures 1-8As shown in the figure, the present utility model provides a conductive terminal 100, which is used for electrically connecting with a plug-in 200. The conductive terminal 100 includes a fixed seat 110, a conductive clamping member 120 and a bracket 130. The clamping member 120 is fixed to the first side 111 of the fixed seat 110, and the bracket 130 is fixed to the second side 112 of the fixed seat 110. The clamping member 120 includes a pair of elastic pieces for clamping the plug-in 200. The bracket 130 includes a floating structure 131 and a connecting member 132. The floating structure 131 is connected between the fixed seat 110 and the connecting member 132, and the floating structure 131 is bent along the first direction (Z-axis or X-axis). The clamping member 120 is fixed to the first side of the fixed seat 110, that is, the clamping member 120 clamps the plug-in 200 along the Y direction. The bracket 130 is fixed to the second side 112 of the fixed seat 110, and the floating structure 131 can absorb the installation position error between the conductive terminal 100 and the plug-in 200, so that the clamping member 130 connected to the fixed seat 110 can float greatly as a whole in the X direction or Z direction, so as to be inserted into the plug-in 200. As Figure 2 As shown in the figure, the connection between the fixed seat 110 and the floating structure 131 can have two forms, a and b. Figure a shows that the floating structure 131 is only bent along the Z-axis, so the whole clamping member 120 can float along the X-axis. Figure b shows that the floating structure 131 is only bent along the X-axis, so the whole clamping member 120 can float along the Z-axis. At the same time, the floating structure 131 can also absorb the stress during vibration and avoid damage to the conductive terminal 100.
[0076] In an alternative embodiment of the present utility model, as Figure 1 shown, the floating structure 131 is also bent along the second direction (Z-axis or X-axis). That is, the floating structure 131 can be bent along the first direction and the second direction at the same time, further improving the flexibility of the clamping member 120. The whole clamping member 120 can float along the Z-axis and X-axis to be inserted into the plug-in 200.
[0077] In an alternative embodiment of the present utility model, as Figure 3 shown, the floating structure 131 includes a first bending section 1311 and a second bending section 1312. The orientation of the Z-axis from the starting point to the ending point of the first bending section 1311 is the first orientation, and the orientation of the Z-axis from the starting point to the ending point of the second bending section 1312 is the second orientation. The first orientation and the second orientation are opposite. Therefore, while ensuring that the whole clamping member 120 can float along the Z-axis and X-axis to be inserted into the plug-in 200, it also avoids occupying a large Z-direction space. Specifically, as Figure 3 shown, the first bending section 1311 is arranged between the fixed seat 110 and the second bending section 1312. The first bending section 1311 first extends obliquely upward from its connection with the fixed seat 110, and the second bending section 1312 extends obliquely downward from its starting point. Of course, the floating structure can also only extend obliquely downward from the fixed seat 110, but Figure 3The structure can save Z - direction space compared with the structure that only extends obliquely downward from the direct fixed seat 110. Relative to Figure 2 the structure that directly extends along the Z - direction or the X - direction in Figure 3 , the bending section in
[0078] extends obliquely upward or obliquely downward, and can simultaneously have the ability to float along the Z - axis and the X - axis. Figure 3 Optionally, as shown in
[0079] In Figure 4 , the floating structure 131 further includes a third bending section 1313. The third bending section 1313 extends obliquely downward from the end point of the second bending section 1312. The setting of the third bending section 1313 makes the floating range of the floating structure 131 larger in the Z - axis and X - axis directions, and makes the position floating space of the clamping member 120 larger. It can be understood that the second bending section 1312 can also be arranged between the fixed seat 110 and the first bending section 1311. In another embodiment of the present utility model, the difference between the length of the second bending section 1312 and the length of the third bending section 1313 is less than or equal to 40% of the length of the third bending section 1313. Setting the lengths of the second bending section 1312 and the third bending section 1313 to be approximately equal makes the floating amplitude of the bracket 130 larger and more flexible in the Z - direction and X - direction. In this embodiment, the floating structure 131 includes three bending sections. Of course, it can also include four or five, and the quantity is not limited.
[0080] In Figure 8 , in another embodiment of the present utility model, the first bending section can also extend obliquely downward from the fixed seat, and the second bending section extends obliquely upward from the intersection point with the first bending section. In this way, it can also meet the requirement of floating the clamping member 120 in the Z - axis and X - axis directions while saving Z - direction space. It can be understood that, under the embodiments disclosed in the present utility model, other deformations are within the protection scope of the present utility model.
[0080] In Figure 8 , in another embodiment of the present utility model, the first bending section can also extend obliquely downward from the fixed seat, and the second bending section extends obliquely upward from the intersection point with the first bending section. In this way, it can also meet the requirement of floating the clamping member 120 in the Z - axis and X - axis directions while saving Z - direction space. It can be understood that, under the embodiments disclosed in the present utility model, other deformations are within the protection scope of the present utility model.
[0081] In Figure 3 , in an alternative embodiment of the present utility model, the intersection point of the fixed seat 110 and the bracket 130 is the starting point A of the floating structure 131, and the intersection point of the floating structure 131 and the connecting member 132 is the end point B of the floating structure 131. The distance between the starting point A and the end point B along the extension direction of the first side 111 (i.e., the X - axis direction) is less than or equal to half of the height of the conductive terminal 100. The smaller the distance between the starting point A and the end point B along the X - axis, the better the floating ability. In another alternative embodiment of the present utility model, inFigure 3 As shown, the Z-direction distance between the end point B of the fixed seat 110 and the floating structure 131 is less than or equal to the height of the clamping member 120.
[0082] In an alternative embodiment of the present utility model, as Figure 1 shown, a hollow structure 133 is provided on the floating structure 131. The provision of the hollow structure 133 allows the floating structure 131 to also have a certain floating space in the Y-axis direction. Coupled with the fact that the floating structure 131 can float along the Z-axis and the X-axis, the floating structure 131 can float in three directions in space, further improving the flexibility of the clamping member 120 and making it easier to insert the plug-in 200 into the conductive terminal 100.
[0083] In an alternative embodiment of the present utility model, as Figure 1 and Figure 3 shown, the fixed seat 110 is a rectangular structure, and paired elastic pieces are respectively connected to two first sides 111 of the fixed seat 110, and the floating structure 131 is connected to two second sides 112 of the fixed seat 110; a through hole 113 is provided in the middle of the fixed seat 110, and the through hole 113 is used for the plug-in 200 to pass through and be inserted into the clamping member 120.
[0084] In an alternative embodiment of the present utility model, as Figure 1 and Figure 5 shown, the connecting member 132 includes a first connecting member 1321 and a second connecting member 1322, and the length of the second connecting member 1322 along the Z-axis is greater than the length of the first connecting member 1321 along the Z-axis. When installing the conductive terminal 100 onto a relevant component, the first connecting member 1321 first contacts the installation position, which can play a positioning role. In another alternative embodiment of the present utility model, the width of the second connecting member 1322 can be less than the width of the first connecting member 1321. Of course, it is also possible to set the width of the second connecting member 1322 to be equal to the width of the first connecting member 1321. In another alternative embodiment of the present utility model, the connecting member 132 includes two first connecting members 1321 and two second connecting members 1322, and the two second connecting members 1322 are arranged diagonally, which is more convenient for positioning. It can be understood that the above are all alternative embodiments of the present utility model that are convenient for positioning and are all within the protection scope of the present utility model.
[0085] In an alternative embodiment of the present utility model, as Figure 1 、 Figure 3 and Figure 5As shown, the conductive terminal 100 includes an auxiliary part 140 for connecting to tooling equipment. When installing the conductive terminal 100 onto relevant components (such as the BMU), it is necessary to grasp and move the conductive terminal 100. For example, it can be adsorbed on the auxiliary part by a suction cup to drive the conductive terminal 100 to move and insert it into the BMU 300 (Battery Management Unit), and then the conductive terminal 100 and the BMU 300 are welded by welding equipment.
[0086] In an alternative embodiment of the present utility model, as Figure 1 shown, the conductive terminal 100 includes a plurality of pairs of elastic pieces (i.e., clamping pieces). When the plug-in 200 deflects in the XY plane, if a pair of elastic pieces with a larger width along the X-axis is plugged, the contact area between the plug-in 200 and this pair of elastic pieces is very small. Figure 1 By arranging multiple pairs of elastic pieces with smaller widths along the X-axis, the contact area between all the elastic pieces and the plug-in 200 can be increased. In another alternative embodiment of the present utility model, as Figure 1 and Figure 3 shown, the elastic piece includes a first elastic piece segment 121 and a second elastic piece segment 122. The first elastic piece segment 121 connects the fixed seat 110 and the second elastic piece segment 122. The width of the first elastic piece segment 121 is smaller than that of the second elastic piece segment 122, so that the elastic piece has better flexibility, especially it is easier for the elastic piece to rotate along the Y-axis. As Figure 6 shown, in another alternative embodiment of the present utility model, a pair of protrusions 123 are arranged inside the pair of elastic pieces 120. The protrusions 123 are used to contact the plug-in 200, which can increase the contact area.
[0087] The present utility model also provides a battery cut-off device (not shown). The battery cut-off device includes a plug-in 200 and the above-mentioned conductive terminal 100. The clamping piece 120 of the conductive terminal 100 clamps the plug-in 200, and the clamping piece 120 and the plug-in 200 are welded and electrically connected. Figure 7 shows the plugged state of the plug-in 200 and the conductive terminal 100. The plugged structure can be used for the parts that need to be electrically connected in the battery cut-off device, including but not limited to the plug connected to the relay and the conductive terminal connected to the BMU. In another embodiment of the present utility model, as Figure 7As shown in the figure, the plug 200 includes a fixing portion 210, a floating portion 220, and a plugging portion 230. The floating portion 220 includes a bending structure. The plugging portion 230 is used to plug into the conductive terminal 100. The floating portion 220 is located between the fixing portion 210 and the plugging portion 230, and a hollow structure is also provided on the floating portion 220. Similarly, the floating portion 220 also includes a plurality of bending segments, and the bending segments are transitioned with small rounded corners, which can meet the three-way floating of the plug 200 itself in the XYZ directions, further improving the flexibility of the plug 200 and the conductive terminal 100 when plugging. If there are multiple plugging and electrical connection structures in the battery cut-off device, it is necessary to insert multiple inserts into multiple conductive terminals respectively and make electrical contact with the multiple conductive terminals respectively. The installation position error between each conductive terminal and each plug should be very small or zero, otherwise multiple pairs of plugs without a floating structure cannot be inserted into multiple conductive terminals simultaneously. In the battery cut-off device provided by the present invention, because both the conductive terminal 100 and the plug 200 include a floating structure, even if there is a certain installation position error, each plug 200 can be inserted into the corresponding conductive terminal 100, greatly reducing the matching difficulty and cost.
[0088] The present invention also provides a battery pack, which includes the above-mentioned battery cut-off device.
[0089] The present invention also provides an electrical device. The electrical device of the present invention includes the above-mentioned battery pack. The electrical device can be, but is not limited to, a mobile phone, a tablet computer, a notebook computer, an electric toy, an electric tool, a battery car, an electric vehicle, a ship, a spacecraft, etc. Among them, the electric toy can include a fixed or mobile electric toy, for example, a game console, an electric vehicle toy, an electric ship toy, an electric aircraft toy, etc., and the spacecraft can include an airplane, a rocket, a space shuttle, a spaceship, etc.
[0090] So far, the technical solutions of the present invention have been described in conjunction with the optional embodiments shown in the drawings. However, those skilled in the art can easily understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
