Problems solved by technology

[0002] With the development of the power industry, the power level of power equipment such as inverters is increasing day by day, and components such as capacitors, switches, relays, and battery modules inside the power equipment explode when the power equipment fails (such as a bus capacitor short circuit). The size is getting bigger and bigger, causing components such as the shell cover in the box shell of the power equipment to blow up, endangering the safety of other equipment and personnel on site

Embodiment 1

[0052] See Figure 1-4 The connecting member 100 provided by the embodiment of the present invention includes a main body 101 and an end connector; the first end of the main body 101 is fixed by one member of the end connecting member 121 and the case, and is specifically a fixture such as a bolt or by welding. The like is fixed to the member; the second end of the main body 101 is directly connected to the other member of the case, in order to improve the connection strength, the second end of the main body 101 is also fixed to the end connector 122.

[0053] The second end of the main body 101 may be disposed directly to the end connector 122, or the second end is laminated with the end connector 122, and simultaneously passes through the member of the casing and the housing member. The fixed connection is improved both the connection strength of the second end and the member, and simplifies the mounting structure of the end connector 122.

[0054] The main body 101 is "U" type, ...

Embodiment 2

[0058] See Figure 5-6 The connecting member 100 provided in this embodiment also includes a main body 101; the end connectors 121, 122, the difference from the first embodiment in the main body 101 is folded into a serpentine.

Embodiment 3

[0060] See Figure 7-9 The connector 100 provided in this embodiment includes a main body 101 and an end connector 102; the main body 101 includes a straight rod 111 hinged from each other, and the first straight rod is departed from the end of the second straight rod and the end. The portion connecting member 102 is hinged, and the second straight rod is facing away from the end of the first straight rod (such as a shell cover 201), the end connector 102 and the other member of the case (such as housing 202) Secure connection.

[0061] In this embodiment, the straight rod 111 is a metal straight rod, and the end connector 102 is a metal end connector.

[0062] The embodiment of the present invention provides a power equipment case, including a first member and a second member that are fixed to each other, further comprising a connecting member 100, a connector 100 provided by the above embodiment; both ends of the main body 101 respectively Connected to the first member and the se...

Abstract

The invention discloses a connecting piece which is used for a box shell of power equipment, the connecting piece comprises a main body piece, two ends of the main body piece are respectively used for being connected with different components of the box shell, and the main body piece can deform; the main body piece is used for exploding in the box shell, and when the different components connected through the main body piece in the box shell are separated from each other, deformation occurs. According to the connecting piece, the main body piece can deform when devices in the box shell explode and different components connected through the main body piece in the box shell are separated from each other, so that the two components connected through the main body piece in the box shell are separated from each other in a small range to form a gap, and the explosion pressure in the box shell is discharged and relieved; and the two components of the box shell are always connected through the main body piece, so that the components of the box shell and explosive foreign matters in the box shell are prevented from flying out, and the safety of equipment and personnel around the site is guaranteed. The invention further discloses the box shell of the power equipment, which uses the connecting piece and can prevent the safety of other equipment and personnel on site from being harmed when internal devices explode.

Description

Technical field [0001] The present invention relates to the field of mechanical industries, and more particularly, relates to a connecting member, further involves a power equipment case case. Background technique [0002] With the development of the power industry, the power level of the power equipment such as inverter is increasing, while the power equipment such as capacitance, switches, relays, battery modules, such as bus capacitance short circuits, exploded, exploding energy Greater, leading to the housing such as housing, such as housing, such as shell cover, hazard the safety of other equipment and personnel. [0003] Therefore, how to solve the internal device of the prior art to explode, the safety of the box shell is fried, and the safety of other equipment and personnel in the field is urgent to solve the problem. Inventive content [0004] In view of this, the present invention provides a connecting member that can explode in the device inside the box housing and d...
