In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

Referring to fig. 1 and 2 together, the shock absorbing system of the present invention will now be described. The shock-absorbing system includes: a housing 1, a first terminal 21 provided on the housing 1, and a second terminal 22 provided on the housing 1; the first terminal 21 and the second terminal 22 are in conductive connection through the current protector 3; a buffer 4 is arranged between the overcurrent protector 3 and the shell 1.

In this way, the first terminal 21 and the second terminal 22 are conductively connected through the overcurrent protector 3, current flows between the first terminal 21 and the second terminal 22, and the overcurrent protector 3 prevents the current between the first terminal 21 and the second terminal 22 from being too large; the overcurrent protector 3 and the shell 1 are separated by the buffer 4 to reduce the vibration of the overcurrent protector 3, so that the overcurrent protector 3 is protected.

Wherein in one embodiment the over-current protector 3 has a predetermined current threshold.

Further, referring to fig. 1 to 2, as an embodiment of the damping system provided by the present invention, the overcurrent protector 3 is a fuse. Thus, the fuse opens when the current reaches the current threshold.

Further, referring to fig. 1 to 2, as an embodiment of the damping system provided by the present invention, the damping member 4 is a silicone block. Therefore, the silica gel block is low in cost, good in elasticity and good in insulativity.

Further, referring to fig. 1 to 2, as a specific embodiment of the damping system provided by the present invention, a positioning plate 5 is disposed on the housing 1, a mounting hole 51 is formed on the positioning plate 5, and the damping member 4 is inserted into the mounting hole 51. Thus, the buffer member 4 is inserted into the mounting hole 51 of the positioning plate 5, and the stability of the self position of the buffer member 4 is ensured.

Further, referring to fig. 1 to 2, as an embodiment of the damping system provided by the present invention, the mounting hole 51 is a rectangular hole. Thus, the rectangular hole is easy to process, and the rectangular buffer member 4 is arranged in the rectangular hole in a penetrating manner and is not easy to rotate.

Further, referring to fig. 1 to 2, as an embodiment of the damping system provided by the present invention, the section of the damping member 4 is rectangular, and the section of the damping member 4 is the same as the mounting hole 51. Thus, the cushion material 4 is less likely to shake in the mounting hole 51.

Further, referring to fig. 1 to 2, as an embodiment of the damping system provided by the present invention, the damping member 4 abuts against the overcurrent protector 3. So, the bolster 4 is inseparable with the contact between the overcurrent protector 3, has promoted overcurrent protector 3's stability.

Further, referring to fig. 1 to 2, as an embodiment of the damping system provided by the present invention, the damping member 4 contacts a central region of the overcurrent protector 3. So, when the bolster 4 exerts external force to the overcurrent protector 3, the bolster 4 can support the overcurrent protector 3 more effectively and keep the stability of the overcurrent protector 3.

Further, referring to fig. 1 to 2, as an embodiment of the damping system provided by the present invention, the positioning plate 5 is spaced apart from the housing 1, and/or the positioning plate 5 is spaced apart from the overcurrent protector 3. So, the interval sets up in order to release bolster 4/5 deformation of locating plate between locating plate 5 and the casing 1, and the interval sets up in order to release bolster 4/5 deformation of locating plate between locating plate 5 and the overcurrent protector 3.

Further, referring to fig. 1 to 2, as an embodiment of the damping system provided by the present invention, the first terminal 21 is shaped like a plate, and the second terminal 22 is shaped like a plate. Thus, the plate-shaped first conductive terminal is convenient to be electrically connected with an external element, and the plate-shaped second conductive terminal is convenient to be electrically connected with the external element.

Specifically, in one embodiment, the mounting hole 51 is opened in a central region of the positioning plate 5. In this way, when the cushion member 4 positioned in the mounting hole 51 applies an external force to the positioning plate 5, the shape of the positioning plate 5 can be kept stable. Specifically, in one embodiment, the central region of the positioning plate 5 is in an overhead state. In this way, the positioning plate 5 is easily released from vibration during the vibration.

Specifically, in one embodiment, the first terminal 21 and the second terminal 22 are each L-shaped. As such, the first and

second terminals

21 and 22 are resistant to bending.

Specifically, in one embodiment, the first terminals 21 extend and bend in a direction away from the housing 1, and the second terminals 22 extend and bend in a direction away from the housing 1. In this manner, the first and

second terminals

21 and 22 are facilitated to be conductively fitted with other terminals outside the housing 1.

Specifically, in one embodiment, the overcurrent protector 3 is located between the first terminal 21 and the second terminal 22. In this way, the first terminal 21 and the second terminal 22 can protect the overcurrent protector 3.

Specifically, in one embodiment, the distance between the positioning plate 5 and the housing 1 is a first distance, the distance between the positioning plate 5 and the overcurrent protector 3 is a second distance, and the first distance is greater than the second distance. Thus, the positioning plate 5 is prevented from colliding with the housing 1 during vibration.

Specifically, in one embodiment, the overcurrent protector 3 has a first plane, and the buffer member 4 has a second plane, and the second plane abuts against the first plane. Thus, the buffer member 4 is closely contacted with the overcurrent protector 3.

Specifically, in one embodiment, the first terminal 21 is supported against the positioning plate 5, and the second terminal 22 is supported against the positioning plate 5. In this way, the vibration of the first terminal 21 can be effectively transmitted to the positioning plate 5 to be offset, and the vibration of the second terminal 22 can be effectively transmitted to the positioning plate 5 to be offset.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
