The components in the integrated distribution box need to be electrically connected with the conductive terminals on the circuit board (PrintedCircuitBoard, PCB), so that the electrical connection efficiency is improved, and the components in the integrated distribution box can be electrically connected with each other through the contact between the inserting sheets and the conductive terminals. However, in the current contact type electrical connection method, when the contact type electrical connection method is applied to a vehicle, the problem that the electrical connection between the tab and the conductive terminal is instantaneously disconnected due to vibration of the vehicle is easily caused. To solve this problem, the present embodiment provides a conductive terminal 10, an electrical connection assembly 100, a battery breaking unit 1000 (shown in fig. 1), and a vehicle 10000 (shown in fig. 5).

Referring to fig. 1, in a first aspect, a conductive terminal 10 according to an embodiment of the present application includes a fixing member 11 and two conductive clamping members 13. The two clamping pieces 13 are oppositely arranged on the fixing piece 11, and the two clamping pieces 13 are used for propping against two opposite sides of the inserting piece 301 extending between the two clamping pieces 13 and form surface contact with at least one side of the inserting piece 301 so as to electrically connect the inserting piece 301 with the conductive terminal 10.

Specifically, the conductive terminal 10 is made of a conductive material including, but not limited to, metal, graphite, conductive polymer, oxide, carbon nanotube, or the like. Among these, metals include, but are not limited to, copper, aluminum, silver, gold, nickel, and the like; oxides include, but are not limited to, copper oxides, zinc oxides, magnesium oxides, and the like. The conductive terminal 10 is used to make electrical connection with other conductive elements by contact, and the conductive terminal 10 of the present application is used to make electrical connection with the tab 301 of the electronic device 300 by surface contact. The fixing member 11 of the present application is used for connection with the base 30 so that a firm connection is formed between the conductive terminal 10 and the base 30.

The clamping member 13 of the present application is of a sheet-like structure so as to form a surface contact with the insert 301. In one embodiment, the clamp 13 may be a monolithic sheet-like structure. In this case, the processing of the clip 13 is relatively simple. In another embodiment, the clamp 13 may comprise a plurality of sub-portions (a plurality of sheet-like structures). At this time, the stability of the clip 13 is good. If one of the sub-portions fails, the remaining sub-portions can still be electrically connected to the insert 301. The two clamping members 13 may be identical or different in structure.

The clamping piece 13 is attached to the corresponding side of the inserting piece 301, so that surface contact is formed between the clamping piece 13 and the inserting piece 301. In one embodiment, one clamp 13 of the two clamps 13 is in contact with a side of the tab 301 to make electrical connection of the tab 301 with the conductive terminal 10. At this time, the insert 301 is free to assemble and only needs to be in surface contact with one of the clamping members 13. In another embodiment, two clamping members 13 are in surface contact with opposite sides of the insert 301. At this time, the area of the surface contact between the clip 13 and the tab 301 is large, and the stability of the electrical connection between the clip 13 and the tab 301 is good. Both clamping members 13 of the present embodiment are in surface contact with the insert 301 to form a secure electrical connection between the conductive terminal 10 and the insert 301.

The clamping piece 13 is of an elastic structure, and the clamping piece 13 can deform under the action of external force. In the case where both the clamping members 13 are in surface contact with the tab 301, it is preferable that the minimum distance between the clamping members 13 is at least smaller than the thickness of the tab 301 in a natural state, so that the two clamping members 13 can abut against opposite sides of the tab 301 with the tab 301 interposed therebetween, whereby a stable ground contact can be formed between the conductive terminal 10 and the tab 301. During the insertion of the tab 301 between the two clamping members 13, the two clamping members 13 deform in a direction away from the other clamping member 13, respectively, so that the tab 301 can extend between the two clamping members 13. After the insert 301 is inserted between the two clamping members 13, the two clamping members 13 respectively collide with opposite sides of the insert 301 due to elastic potential energy of the clamping members 13 themselves. In the case where the minimum distance between the two clamping members 13 is at least smaller than the thickness of the insert 301, there may be a space between the two clamping members 13 or no space between the two clamping members 13 in a natural state.

The conductive terminal 10 of the embodiment of the present application is provided with two clamping members 13, and the clamping members 13 are in surface contact with the insert 301, so as to realize electrical connection between the insert 301 and the conductive terminal 10. Because the clamping piece 13 is in surface contact with the inserting piece 301, the inserting piece 301 and the conductive terminal 10 can always keep in contact during the vibration process of the vehicle, so that the problem of instant disconnection is avoided.

And, the conductive terminal 10 of this application only includes mounting 11 and two clamping pieces 13, compares in the structure of current conductive terminal 10, and the conductive terminal 10 of this application structure is comparatively simple, and the materials are less, can save the cost.

The conductive terminal 10 is further described below with reference to the accompanying drawings.

Referring to fig. 1, in some embodiments, the fixing member 11 includes a first end 115 and a second end 117 opposite to each other in the first direction X, one ends of the two clamping members 13 extend from the first end 115 of the fixing member 11 and the second end 117 of the fixing member 11, respectively, and the other ends of the two clamping members 13 are free ends.

Referring to fig. 1 and 2, in some embodiments, the fixing member 11 includes a fixing portion 111 and a mounting portion 113. The mounting portion 113 extends from the fixing portion 111 in a bending manner, and the mounting portion 113 and the clip 13 extend toward opposite sides of the fixing portion 111. Specifically, the fixing portion 111 is used for connecting the mounting portion 113 and the clamping member 13, the mounting portion 113 and the clamping member 13 each extend from the fixing portion 111 in a bending manner, and the mounting portion 113 and the clamping member 13 extend toward opposite sides of the fixing portion 111, respectively.

The mounting portion 113 is used for connecting with the base 30 so that the conductive terminal 10 is firmly connected to the base 30. Preferably, the mounting portion 113 and the base 30 are connected by welding, so that a good electrical connection between the mounting portion 113 and the base 30 is achieved and the connection between the mounting portion 113 and the base 30 is stable. The cross-sectional shape of the mounting portion 113 may be, but is not limited to, circular, elliptical, triangular, quadrilateral, other polygonal, etc., and the cross-sectional shape of the mounting portion 113 of the present application is quadrilateral. The number of the mounting portions 113 may be, but is not limited to, one, two, three, or more. In the case where the number of the mounting portions 113 is one, the mounting portions 113 may extend from any position of the fixing portion 111. The cross-sectional area of the mounting portion 113 is at least smaller than that of the fixing portion 111, and preferably, in the case that the cross-sectional area of the mounting portion 113 is large, the mounting portion 113 is connected with the base 30 by welding, so that the connection strength of the mounting portion 113 and the base 30 is high, and the connection of the conductive terminal 10 and the base 30 is stable. In the case where the number of the mounting portions 113 is plural, the mounting portions 113 are uniformly or non-uniformly distributed on one side of the fixing portion 111, and the cross-sectional areas of the plural mounting portions 113 may be the same or different. At this time, the connection strength between the mounting portion 113 and the base 30 is high, and the connection between the conductive terminal 10 and the base 30 is stable. The number of the mounting portions 113 in the present embodiment may be four, five or six, and in the case that the number of the mounting portions 113 is six, the connection between the conductive terminal 10 and the base 30 is more stable.

Referring to fig. 1 and 2, in some embodiments, the fixing portion 111 includes a first side 1111 and a second side 1113 opposite to each other, the mounting portion 113 is located on the first side 1111 of the fixing portion 111, and the clamping member 13 is located on the second side 1113 of the fixing portion 111. Wherein, the first side 1111 of the fixing portion 111 is a side close to the base 30, and the second side 1113 of the fixing portion 111 is a side far from the base 30. The mounting portion 113 extends from the first side 1111 of the fixing portion 111 to connect with the base 30, and the clamping member 13 extends from the second side 1113 of the fixing portion 111 to make surface contact with the insert 301.

Referring to fig. 1 to 3, in some embodiments, the clamping member 13 includes a connecting portion 131 and a clamping portion 133. One end of the connecting portion 131 is connected to the fixing member 11. One end of the clamping portion 133 is connected to the other end of the connecting portion 131, and the clamping portion 133 is configured to be in surface contact with the insert 301. In the second direction Y along the first side 1111 of the fixing portion 111 to the second side 1113 of the fixing portion 111, the connection portion 131 of one clip 13 is inclined in a direction approaching the connection portion 131 of the other clip 13.

The connecting portion 131 is a structure for connecting other elements, and the connecting portion 131 of the present application is used for connecting the fixing portion 111 and the clamping portion 133. The cross-sectional area of the fixing portion 111 is at least greater than that of the insert 301, one end of the connecting portion 131 is connected to one end of the fixing portion 111 (the first end of the fixing portion 111 or the second end of the fixing portion 111), and the other end of the connecting portion 131 is connected to the clamping portion 133 in surface contact with the insert 301, so that an angle between the connecting portion 131 and the fixing portion 111 is less than 90 °. In the case that the angle between the connecting portion 131 and the fixing portion 111 is smaller than 90 °, the force of the connecting portion 131 on the clamping portion 133 can further enhance the contact strength between the clamping portion 133 and the insert 301, so that a stable connection between the clamping portion 133 and the insert 301 is further achieved.

The second direction Y is perpendicular to the first direction X, and in some embodiments, in the second direction Y, the clamping portion 133 is parallel to the insert 301, so that when the clamping member 13 abuts against the insert 301, the clamping portion 133 can be attached to the insert 301, thereby achieving good surface contact between the clamping portion 133 and the insert 301. After the insert 301 extends between the two clamping members 13, the insert 301 may be perpendicular or inclined with respect to the fixing portion 111. In the embodiment of the present utility model, the insert 301 is perpendicular to the fixing portion 111, that is, the extending direction of the insert 301 is parallel to the second direction Y, and the extending direction of the clamping portion 133 is also parallel to the second direction Y, so that the clamping portion 133 can be in good surface contact with the opposite side surfaces of the insert 301.

With continued reference to fig. 1-3, further, in some embodiments, the clamping member 13 further includes a bending portion 135. One end of the bending portion 135 is connected to the other end of the clamping portion 133, the other end of the bending portion 135 is a free end, and the bending portion 135 of one clamping piece 13 is inclined in a direction away from the bending portion 135 of the other clamping piece 13 along the second direction Y.

Wherein the bending portion 135 is used to further maintain the clamping portion 133 parallel to the second direction Y, thereby further ensuring good surface contact between the clamping portion 133 and the insert 301. The angle between the bending part 135 of one clamping piece 13 and the side of the clamping part 133 away from the inserting piece 301 is smaller than 90 degrees, the angle between the bending part 135 of the other clamping piece 13 and the side of the clamping part 133 away from the inserting piece 301 is also smaller than 90 degrees, and the angles between the bending parts 135 of the two clamping pieces 13 and the side of the clamping part 133 away from the inserting piece 301 can be the same or different. With the tab 301 separated from the conductive terminal 10, the bent portion 135 can facilitate removal of the tab 301 from the two clips 13.

The connecting portion 131 of one clamping member 13 extends from one end of the fixing portion 111 and gradually approaches the other clamping member 13, the clamping portion 133 extends from the connecting portion 131, the clamping portion 133 extends in the second direction Y, the bending portion 135 extends from the clamping portion 133, and the bending portion 135 gradually moves away from the other clamping member 13. At this time, the insert 301 may be inserted between the two clips 13 from the connection portion 131 toward the bending portion 135, or the insert 301 may be inserted between the two clips 13 from the bending portion 135 toward the connection portion 131. In the case where the tab 301 is inserted between the two clips 13 from the bending portion 135 toward the connecting portion 131, the bending portion 135 can guide the insertion of the tab 301.

In other embodiments, the clamping member 13 may not include the bending portion 135. At this time, the material consumption of the clamping member 13 is small, the material can be saved, and the processing steps are relatively simple.

Referring to fig. 1 and 2, in some embodiments, at least one clamping member 13 includes a plurality of sub-clamping members 137. The plurality of sub-clamps 137 are arranged at intervals in the fixing member 11 along the third direction Z, one end of the sub-clamp 137 is connected to the fixing member 11, the other end is a free end, and the third direction Z is perpendicular to the first direction X. Wherein the first direction X, the second direction Y and the third direction Z are all perpendicular to each other.

In particular, in the case where the clamping member 13 includes a plurality of sub-clamping members 137, the stability of the clamping member 13 is good. If there is a dimensional or surface defect in the individual sub-clip 137, the remaining sub-clips 137 are still able to maintain a stable electrical connection with the tab 301.

The plurality of sub-clamps 137 may be uniformly or non-uniformly arranged at one end of the fixing member 11, and in case that the sub-clamps 137 are uniformly arranged at one end of the fixing member 11, the intervals between the plurality of sub-clamps 137 are the same. In the case where the sub-holders 137 are unevenly arranged at one end of the fixing member 11, the pitches between the plurality of sub-holders 137 are different. The clamping member 13 may include two, three, four or more sub-clamping members 137, and the number of sub-clamping members 137 included in two clamping members 13 may be the same or different. Both clamping members 13 of the present application comprise four sub-clamping members 137, and the two clamping members 13 are identical in structure.

Each sub-clip 137 includes a sub-connection portion, a sub-clip portion, and a sub-bend portion. The sub-connecting portion extends from one end of the fixing member 11, the sub-clamping portion extends from the sub-connecting portion, and the sub-bending portion extends from the sub-clamping portion. The sub-connection portion is used for connecting the fixing portion 111 and the sub-clamping portion, the sub-clamping portion is used for being in surface contact with the inserting piece 301 to achieve electric connection, and the sub-bending portion is used for enabling the sub-clamping portion to be parallel to the second direction Y. The bending angles of the plurality of sub-bending parts can be the same or different, and preferably, the bending angles of the plurality of sub-bending parts are the same so as to facilitate processing. The widths of the plurality of sub-holders 137 in the third direction Z may be the same or different.

In the third direction Z, the width (overall width) of the grip 13 may be greater than or equal to the width of the tab 301. In one embodiment, the width of the grip 13 is greater than the width of the tab 301. At this time, within the assembly tolerance range of the clamping member 13 and the insert 301, the clamping portion 133 of the clamping member 13 may be bonded to the entire surface of the insert 301 in the third direction Z, so that the contact area between the clamping portion 133 and the insert 301 is large, and stable electrical connection between the clamping portion 133 and the insert 301 is achieved. In another embodiment, the width of the clip 13 is equal to the width of the insert 301. At this time, the accuracy of the fitting of the clip 13 and the tab 301 is high, and whether the clip 13 is aligned with the edge of the tab 301 can be detected visually at the time of fitting. With the clip 13 and the insert 301 assembled and edge aligned, the clip portion 133 of the clip 13 may be entirely in contact with the insert 301 in the third direction Z, thereby making the contact surface of the clip portion 133 and the insert 301 larger to achieve a stable electrical connection of the clip portion 133 and the insert 301.

Referring to fig. 1 and 2, in some embodiments, the contact area between the clamping member 13 and at least one side of the insert 301 is greater than or equal to 4 mm.

The contact area between the clamping piece 13 and the inserting piece 301 is smaller than 4mm ² In the case of the above, the contact area between the clip 13 and the tab 301 is small, and the connection stability between the clip 133 and the tab 301 is poor. And the contact area between the clamping piece 13 and the inserting piece 301 is smaller than 4mm ² In the case of the clamping member 13 being electrically connected to the blade 301, the requirement for excessive current cannot be met. In one embodiment, the contact area between one clamping piece 13 and one side of the inserting piece 301 is more than or equal to 4mm ² For example, the contact area of one of the clamping members 13 and one side of the insert 301 may be 4mm, 5mm, 6mm, or the like. At this time, the normal electrical connection strip between the conductive terminal 10 and the insert 301 can be satisfiedThe conductive terminal 10 and the tab 301 are electrically connected to satisfy the passage of a large current. In another embodiment, the contact area of the two clamping members 13 and the opposite sides of the insert 301 is 4mm or more ² For example, the contact area of both the clamping members 13 and one side of the insert 301 may be 4mm, 5mm, 6mm, or the like. At this time, the conductive terminal 10 and the tab 301 can meet the normal electrical connection condition, and the conductive terminal 10 and the tab 301 can be electrically connected to meet the large current.

The tab 301 is electrically connected to the conductive terminal 10 to make an electrical connection between the tab 301 and the PCB.

Referring to fig. 1 to 3, in some embodiments, the base 30 is provided with a mounting hole 31, and the mounting portion 113 of the fixing element 11 is inserted into the mounting hole 31. At this time, the manner in which the fixing member 11 is mounted on the PCB is relatively simple and convenient.

The opening shape of the mounting hole 31 may be, but not limited to, a circle, an ellipse, a triangle, a quadrangle, or other polygons, and the opening shape of the mounting hole 31 in the embodiment of the present application is a circle. The number of mounting holes 31 and the number of mounting portions 113 may be the same.

The electrical connection assembly 100 of the embodiment of the present application provides two clamping members 13, and makes the clamping members 13 in surface contact with the tab 301, so as to achieve electrical connection between the tab 301 and the conductive terminal 10. Because the clamping piece 13 is in surface contact with the inserting piece 301, the inserting piece 301 and the conductive terminal 10 can always keep in contact during the vibration process of the vehicle, so that the problem of instant disconnection is avoided.

Referring to fig. 3 and 4, in a third aspect, the embodiment of the present application further provides a battery breaking unit 1000, where the battery breaking unit 1000 includes an electronic device 300 and the electrical connection assembly 100 according to any of the above embodiments. The electronic device 300 is provided with a tab 301. The insert 301 extends between the two clamping members 13 and is in surface contact with both clamping members 13.

Among them, the battery breaking unit 1000 (Battery Disconnect Unit) is used to cut off a circuit unit of the battery when overcharge, over-temperature, over-current, etc. of the battery occur, so as to avoid danger. Electronic device 300 includes, but is not limited to, resistors, capacitors, inductors, semiconductors, relays, and the like. The insert 301 is made of a conductive material including, but not limited to, metal, graphite, conductive polymer, oxide, or carbon nanotubes, etc. Among these, metals include, but are not limited to, copper, aluminum, silver, gold, nickel, and the like; oxides include, but are not limited to, copper oxides, zinc oxides, magnesium oxides, and the like. The tab 301 is adapted to make surface contact with the clip 13 to make electrical connection with the conductive terminal 10 and thus with the PCB. The electronic device 300 is plugged into the conductive terminal 10 of the electrical connection assembly 100 through the tab 301 to make an electrical connection, thereby enabling the electronic device 300 to be quickly mounted on the PCB. In the process of plugging the plug 301 with the conductive terminal 10, two opposite sides of the plug 301 respectively correspond to the clamping parts 133 of the two clamping pieces 13, so that the plug 301 can be in surface contact with both the two clamping pieces 13 when the plug 301 stretches into between the two clamping pieces 13.

Referring to fig. 3, in some embodiments, at least one side of the insert 301 is provided with a groove 3011, and the groove 3011 is configured to at least partially receive the clamping portion 133 of the corresponding clamping member 13. Specifically, the groove 3011 can play a limiting role on the clamping portion 133, and the groove 3011 further enhances the connection stability of the clamping member 13 and the insert 301. During running vibration of the vehicle 10000, the clamping piece 13 is located in the groove 3011 and is not easy to separate from the inserting piece 301, so that the risk of instantaneous disconnection between the conductive terminal 10 and the inserting piece 301 is reduced. The groove 3011 can also facilitate the installation of the tab 301, and in the process of plugging the tab 301 into the conductive terminal 10, if the groove 3011 is visually detected to be matched with the clamping portion 133, the tab 301 and the conductive terminal 10 are installed in place in the second direction Y.

The clamping portion 133 contacts the inner wall surface of the groove 3011 to achieve electrical connection of the conductive terminal 10 and the tab 301. The extending direction of the inner wall of the groove 3011 and the second direction Y are parallel to each other so as to be attached to the clip portion 133 to achieve surface contact.

In one embodiment, one side of tab 301 is provided with a groove 3011. At this time, the processing of the insert 301 is simpler. In another embodiment, the tab 301 is provided with grooves 3011 on opposite sides. At this time, the grooves 3011 can limit both the two clips 13, and the two grooves 3011 can enhance the connection stability between the two clips 13 and the tab 301.

Referring to fig. 2 and 3, in some embodiments, the base 30 is provided with a through hole 33, the fixing portion 111 of the fixing member 11 is provided with a through hole 1115, and the insert 301 extends between the two clamping members 13 through the through hole 33 and the through hole 1115.

Here, the through hole 33 and the through hole 1115 are space structures for other elements to pass through. The through hole 33 corresponds to the through hole 1115, and the cross-sectional areas of the through hole 33 and the through hole 1115 are larger than or equal to the cross-sectional area of the insert 301, so that the insert 301 penetrates through the through hole 33 and the through hole 1115, and the cross-sectional areas of the through hole 33 and the through hole 1115 can be the same or different. The insert 301 of this application is inserted from the base 30 one side that is kept away from conductive terminal 10, and insert 301 wears to establish through-hole 33 and perforation 1115 in proper order to stretch into between two clamping pieces 13, finally support the opposite sides of insert 301 by two clamping pieces 13, thereby realize conductive terminal 10 and the electric connection of electronic device 300.

The battery breaking unit 1000 of the present embodiment is provided with two clamping members 13, and the clamping members 13 are in surface contact with the tab 301, so that the tab 301 and the conductive terminal 10 are electrically connected. Because the clamping piece 13 is in surface contact with the inserting piece 301, the inserting piece 301 and the conductive terminal 10 can always keep in contact during the vibration process of the vehicle, so that the problem of instant disconnection is avoided.

Referring to fig. 5, in a fourth aspect, the embodiment of the present application further provides a vehicle 10000, where the vehicle 10000 includes the battery breaking unit 1000 of the above embodiment. The vehicle 10000 can be an electric vehicle, a hybrid vehicle, a fuel vehicle, or the like.

In the vehicle 10000 according to the embodiment of the present application, two clips 13 are provided, and the clips 13 are brought into surface contact with the tab 301, so that the tab 301 and the conductive terminal 10 are electrically connected. Since the clamping member 13 is in surface contact with the insert 301, the insert 301 and the conductive terminal 10 can always keep in contact during the vibration of the vehicle 10000, so that the problem of instantaneous disconnection is avoided.
