Description

Technical Field

[0001] The present application relates to the technical field of fuses, and in particular to a fuse for energy storage. Background Art

[0002] A fuse is an electrical appliance that uses the heat generated by itself to melt the fuse when the current exceeds the specified value, thereby disconnecting the circuit. Fuses are widely used in power distribution systems or energy storage systems. Fuses are usually connected to micro switches to determine whether the inside of the fuse is normal. In the related art, a fuse includes a housing, two support plates are arranged in the housing, a plurality of fuse pieces are arranged between the two support plates, and a gap is provided between two adjacent fuse pieces.

[0003] If two adjacent fuse links are in contact, the temperature rise between the two fuse links will be too high, resulting in excessive loss between the two fuse links, thus affecting the normal use of the fuse.

[0004] Therefore, when the staff is welding the fuse, they need to manually grasp the interval between two adjacent fuses, resulting in different spacings between the two adjacent fuses, affecting the performance of each fuse. If the interval between two adjacent fuses is too small, the two adjacent fuses may contact each other, affecting the use of the fuse. Summary of the invention

[0005] In order to improve the problem that the interval between two adjacent fuse pieces is difficult to determine, the present application provides a fuse for energy storage.

[0006] The present application provides a fuse for energy storage, which adopts the following technical solution: A fuse for energy storage includes a shell, wherein two support plates are arranged in the shell, a plurality of fuse pieces are arranged on the support plates, a plurality of placement slots are opened on the support plates, the placement slots are for the fuse pieces to be inserted, and the spacing between two adjacent placement slots is the same.

[0007] By adopting the above technical solution, the distance between two adjacent placement grooves is the same, and the fuse pieces are inserted into the placement grooves, so that the distance between two adjacent fuse pieces is the same, so that the staff can be more accurate when welding the fuse pieces, and the distance between two adjacent fuse pieces can be fixed, reducing the errors caused by the staff during welding, and then making it difficult for two adjacent fuse pieces to contact, so that the fuse can be used normally.

[0008] Optionally, a connecting plate is provided on the shell, and an installation groove for inserting a micro switch is opened on the shell. The connecting plate is slidably connected to a limit plate, and a limit block is provided on the limit plate. The limit block is used to be inserted into the groove of the micro switch. When the limit block is inserted into the groove of the micro switch, the micro switch is fixed in the installation groove.

[0009] By adopting the above technical solution, the micro switch can be fixed on the shell by inserting the limit block into the groove of the micro switch and the micro switch into the installation groove. Since the limit plate is slidably connected to the connecting plate, people can manually drive the limit plate to slide, so that the limit plate will not restrict the micro switch, thereby allowing the micro switch to be fixed on the connecting plate.

[0010] Optionally, a fixing strip is provided on the shell, a fixing hole is opened on the fixing strip, an elastic component is provided on the limit plate, and the elastic component can be inserted into the fixing hole. When the elastic component is inserted into the fixing hole, the limit block is inserted into the groove of the micro switch.

[0011] By adopting the above technical solution, the elastic component is inserted into the fixing hole, so that the hole wall of the fixing hole limits the elastic component, allowing the elastic component to stably fix the fixing strip and the limiting plate to each other, thereby making it difficult for the limiting plate to slide on the connecting plate, so that the limiting block can stably fix the micro switch, further reducing the possibility of the micro switch detaching from the connecting plate.

[0012] Optionally, a dovetail groove is provided on the shell, and the dovetail groove penetrates to the end face of the shell. A dovetail block is provided on the connecting plate. When the dovetail block is inserted into the dovetail groove, the connecting plate is installed on the shell.

[0013] By adopting the above technical solution, the dovetail groove penetrates through the end face of the shell, so that the dovetail block can be inserted into the dovetail groove from the direction in which the dovetail groove penetrates, so that the groove wall of the dovetail groove limits the dovetail block, so that the connecting plate can be fixed on the shell, reducing the possibility of movement of the connecting plate on the shell.

[0014] Optionally, a stop ring is rotatably connected to the shell, the stop ring is provided with a through hole for the connecting plate to pass through, and the connecting plate is provided with a stop hole for the stop ring to be inserted into, and when the stop ring is inserted into the stop hole, the connecting plate is fixed to the shell.

[0015] By adopting the above technical solution, people rotate the stop ring to allow the connecting plate to pass through the through hole, and then rotate the stop ring to allow the stop ring to be inserted into the stop hole, so that the stop ring can limit the connecting plate, thereby preventing the connecting plate from sliding in the dovetail groove, further enhancing the firmness of the connecting plate on the shell; at the same time, rotating the stop ring can fix the connecting plate, simplifying the operation of installing the connecting plate, so as to facilitate quick installation of the connecting plate.

[0016] Optionally, a limiting member is slidably connected to the fixing bar, a limiting groove for inserting the limiting member is opened on the stopping ring, the elastic component can drive the limiting member to be inserted into the limiting groove, and when the limiting member is inserted into the limiting groove, the stopping ring is located in the stopping hole.

[0017] By adopting the above technical solution, the elastic component is inserted into the fixing hole, so that the elastic component pushes the limit piece to slide on the fixing bar, and the limit piece can be smoothly inserted into the limit groove, so that the groove wall of the limit groove limits the limit piece, allowing the limit piece to limit the stop ring, thereby reducing the possibility of the stop ring rotating on the shell, and further realizing the fixation of the stop ring to the connecting plate.

[0018] Optionally, the bottom wall of the limiting groove is inclined between a direction away from the fixing bar and a direction away from the connecting plate.

[0019] By adopting the above technical scheme, the bottom wall of the limit groove is tilted toward the direction away from the fixing strip and toward the direction away from the connecting plate, so that the limit member can drive the stop ring to rotate along the tilted direction of the limit groove, so that the limit member can automatically drive the stop ring to rotate, so that when the micro switch is fixed to the connecting plate, the connecting plate can be fixed on the shell, avoiding the situation where the connection between the connecting plate and the shell is unstable and causes problems with the micro switch; if the stop ring is inserted into the stop hole, the fixing block is difficult to insert into the fixing hole, so that people can know that the connecting plate is not installed properly and needs to be reinstalled, so that people can check whether the installation of the connecting plate is complete.

[0020] Optionally, the elastic component includes an elastic spring and a fixed block, the elastic spring is arranged on the limiting plate, the fixed block is arranged on the elastic spring, and the elastic spring drives the fixed block to be inserted into the fixed hole.

[0021] By adopting the above technical solution, the fixing block is driven to move by the elastic spring, and the fixing block is inserted into the fixing hole. The hole wall of the fixing hole limits the fixing block, and the fixing block and the fixing bar are fixed to each other, so that the limit plate can be stably fixed on the connecting plate, and the limit plate and the limit block can stably limit the micro switch.

[0022] Optionally, a rotation hole is provided on the fixing block, and a rotation rod is rotatably connected in the rotation hole. When the rotation rod abuts against a side of the fixing bar away from the connecting plate, the fixing block is fixed in the fixing hole.

[0023] By adopting the above technical solution, the rotating rod rotates in the rotating hole, so that the rotating rod can abut against the side of the fixing bar away from the connecting plate, so that the rotating rod restricts the fixing block, so that the fixing block is difficult to move in the fixing hole, so that the fixing block can be fixed in the fixing hole, and further the connection between the fixing block and the fixing bar is made firm to each other, reducing the possibility of the fixing block being separated from the fixing hole due to vibration.

[0024] Optionally, a movable spring is provided on the limit plate, and the movable spring drives the limit block to disengage from the slot of the micro switch.

[0025] By adopting the above technical solution, the limit plate is driven to move by moving the spring, so that the limit block is separated from the groove of the micro switch, so that the limit block does not limit the micro switch, and people do not need to manually drive the limit plate to move. People can directly take the micro switch out of the connecting plate, so that people can replace the micro switch.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The micro switch can be fixed on the housing by inserting the limit block into the groove of the micro switch and the micro switch into the mounting groove. Since the limit plate is slidably connected to the connecting plate, people can manually drive the limit plate to slide so that the limit plate does not restrict the micro switch, thereby allowing the micro switch to be fixed on the connecting plate.

[0027] 2. People rotate the stop ring to allow the connecting plate to pass through the through hole, and then rotate the stop ring to insert the stop ring into the stop hole, so that the stop ring can limit the connecting plate, so that the connecting plate is not easy to slide in the dovetail groove, and the firmness of the connecting plate on the shell is further enhanced; at the same time, the stop ring can be rotated to fix the connecting plate, simplifying the operation of installing the connecting plate, so as to facilitate the quick installation of the connecting plate.
