Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following provides a detailed description of the technical solution of the present invention with reference to the accompanying drawings.

As shown, the electrical chassis includes a housing cover 10, a housing 20, an electrical component 30, and a display 40.

The electrical assembly 30 comprises a backplane 302, a plurality of electrical components and a plurality of interfaces 301, the interfaces 301 being for plug connectors. The electrical assembly 30 is provided with interfaces 301 on both sides. Each electrical component and each interface 301 are integrated on a base plate 302.

The housing 20 is a unitary structure, and the housing 20 includes a bottom wall 201 and two oppositely disposed end walls 202, and the end walls 202 are substantially perpendicular to the bottom wall 201.

The housing cover 10 is also a unitary structure, the housing cover 10 is covered on the housing 20, the housing cover 10 includes a top wall 102 and two opposite side walls 101, and the side walls 101 are substantially perpendicular to the top wall 102. The length of the side wall 101 is longer than the end wall 202. The top wall 102 and the side walls 101 of the cover 10 and the bottom wall 201 and the end walls 202 of the housing 20 together enclose a receiving cavity for receiving the electrical component 30.

The two side walls 101 are provided with through holes a for extending the interfaces 301 at two sides of the electrical component 30, the side walls 101 can be elastically deformed, and when the side walls 101 are in an undeformed state, the distance between the two side walls 101 is smaller than the distance between the interfaces 301 at two sides of the electrical component 30.

The top wall 102 is provided with a display opening b, the display 40 is fixed on the inner side of the top wall 102, and the display interface of the display 40 is displayed through the display opening b on the top wall 102.

The case cover 10 further comprises a fixing assembly, a group of fixing assemblies are respectively arranged at two ends of the case cover 10, the fixing assembly is located on the inner side of the end wall 202, a first connecting hole used for penetrating the fastening bolt 50 is formed in the fixing assembly, a second connecting hole used for penetrating the fastening bolt 50 is formed in the position, corresponding to the first connecting hole, of the end wall 202, and the end wall 202 and the fixing assembly are fixed through the fastening bolt 50.

The electric cabinet has few parts and low manufacturing cost and assembly cost. Specifically, the assembling process of the electrical cabinet is as follows:

the electrical component 30 is assembled with the housing 20, and specifically, the bottom plate 302 of the electrical component 30 is fixed on the bottom wall 201 of the housing 20 by fastening screws.

Then, the housing cover 10 and the housing 20 are assembled together, specifically, the housing cover 10 is tilted to allow the interface 301 of the first side of the electrical component 30 to penetrate into the through hole a of the sidewall 101 of the first side of the housing cover 10, and then the housing cover 10 or the housing 20 is rotated.

Since the distance between the interfaces 301 on the two sides is greater than the distance between the side walls 101 on the two sides, the side walls 101 can be elastically deformed, so that the interfaces 301 on the second side of the electrical component 30 can be squeezed into the space between the two side walls 101 along with the rotation of the housing cover 10 or the housing 20, and at this time, the side walls 101 on the second side can be supported by the interfaces 301 on the second side to be outwardly deformed.

Then, as the housing cover 10 or the housing 20 continues to rotate, the interface 301 on the second side reaches the position of the through hole a of the sidewall 101 on the second side, and thus penetrates into the through hole a of the sidewall 101 on the second side, at this time, the supporting force of the interface 301 on the second side to the sidewall 101 on the second side disappears, and the sidewall 101 on the second side can be restored to the undeformed state under the action of its own elasticity.

Thereafter, the housing cover 10 and the housing 20 are fastened by the fastening bolts 50, specifically, the fastening bolts 50 are passed through the first connection holes on the fixing members and the second connection holes on the end walls 202 to achieve fastening.

When assembled, the connectors 301 on both sides of the electrical component 30 respectively pass through the through holes a of the corresponding side walls 101 and extend out of the side walls 101, so that the plug can be conveniently plugged into the connectors when in use. Meanwhile, the interfaces 301 on the two sides penetrate through the through holes a on the two side walls 101 of the housing cover 10, so that the housing cover 10 can be limited.

Specifically, the extension length of the interface 301 on the first side of the electrical component 30 relative to the sidewall 101 on the first side of the housing cover 10 is L1, and the extension length of the interface 301 on the second side of the electrical component 30 relative to the sidewall 101 on the second side of the housing cover 10 is L2. L2 may be smaller than L1, so that, during assembly, the first side interface 301 is inserted into the through hole a of the first side sidewall 101, and then the housing cover 10 or the housing 20 is rotated to insert the second side interface 301 into the through hole a of the second side sidewall 101, because the first side interface 301 has a longer extension length, when the housing cover 10 or the housing 20 is rotated, the second side interface 301 is not easy to be disengaged from the through hole a, and because the second side interface 301 has a shorter extension length, during assembly, the deformation amount of the second side sidewall 101 is not too large, and thus the second side interface is easy to return to an undeformed state.

In the illustrated embodiment, a plurality of interfaces 301 are provided on a first side of the electrical component 30, and the interfaces 301 are arranged in sequence along the length direction of the sidewall 101 to form a long interface group. And, the through-hole a on the first side wall 101 of the case cover 10 is set to be a long strip-shaped hole extending along the length direction of the side wall 101, and the long strip-shaped interface group penetrates into the long strip-shaped hole. Thus, the assembly is more convenient.

In the illustrated embodiment, each set of fastening assemblies includes three fasteners 103, wherein one fastener 103 is disposed at an end of one side wall 101, one fastener 103 is disposed at an end of the other side wall 101, and one fastener 103 is disposed at an end of the top wall 102. This arrangement makes it possible to fix the cover 10 and the housing 20 more firmly. Of course, in practical implementation, the number of the fixing members 103 of each set of fixing assemblies is not limited to three.

In the scheme shown in the figure, the distance between the outer side faces of the two groups of fixing assemblies is basically the same as the distance between the two end walls 202, so that the outer side faces of the two groups of fixing assemblies can be in fit contact with the inner side faces of the two end walls 202 in the assembling process, a guiding effect is achieved, and the assembling consistency is ensured.
