Referring to fig. 1 to 8, the present embodiment provides a housing of a communication apparatus including a magnesium alloy case 10, a mounting block 20, and a connector 30. The magnesium alloy case 10 has a housing chamber for housing electronic components of the communication device. The magnesium alloy case 10 is lighter than the aluminum alloy case of the prior art, thereby reducing the weight of the communication device and facilitating the carrying and deployment of the communication device.
Specifically, the mounting block 20 is embedded in the magnesium alloy case 10, and a mounting hole 21 is provided on one surface of the mounting block 20 exposed outside the magnesium alloy case 10. The communication device may be fixedly installed at a preset position through the installation hole 21, and in a normal case, the connection member connected with the installation hole 21 is a stainless steel connection member, and when the stainless steel connection member is connected with the installation hole 21, the installation block 20 is in direct contact with the stainless steel connection member instead of the magnesium alloy case 10, so that electrochemical corrosion between the stainless steel connection member and the magnesium alloy case 10 can be prevented. For example, there may be a plurality of mounting blocks 20, and the plurality of mounting blocks 20 may be embedded in different positions on the same surface of the magnesium alloy case 10 according to actual needs; or can be embedded on two adjacent surfaces of the magnesium alloy box body 10 according to actual needs; the device can be embedded at any position of any surface of the magnesium alloy box 10 according to actual needs, so long as the device is convenient for fixing communication equipment, and no description is repeated here.
The connector 30 is mounted on the magnesium alloy case 10 for interconnecting an external power source, a digital signal, a radio frequency signal, or the like with an electronic component located in the magnesium alloy case 10. The connector 30 may be mounted on the end face of the magnesium alloy case 10, or may be mounted on any face of the magnesium alloy case 10 according to actual needs, as long as the requirements of the present embodiment can be satisfied, and is not particularly limited herein. The number of the connectors 30 may be plural, and the plural connectors 30 may be mounted on the same surface of the magnesium alloy case 10 according to actual needs, or may be mounted on different surfaces of the magnesium alloy case 10, so long as the connectors 30 are convenient to connect with an external power source, a digital signal, a radio frequency signal, or the like, and no specific limitation is imposed herein.
The connector 30 is typically a stainless steel connector. The outer surface of the magnesium alloy case 10 is convexly provided with a surrounding wall 13, the surrounding wall 13 surrounds the periphery of the connector 30, and a first dispensing groove 14 is formed between one surface of the surrounding wall 13 facing the connector 30 and the outer peripheral surface of the connector 30, and the first dispensing groove 14 is used for accommodating sealant. Specifically, when the sealant is injected into the first adhesive slot 14, the sealant can seal the edge of the contact surface between the magnesium alloy case 10 and the connector 30, so as to prevent air from entering between the contact surfaces between the magnesium alloy case 10 and the connector 30, and thus, the occurrence of electrochemical corrosion can be prevented. The sealant may be, for example, a hot melt adhesive, or other substances that can adhere to the inside of the first adhesive slot 14 and isolate air from the outside of the first adhesive slot 14.
The housing of the communication apparatus provided in the present embodiment includes a magnesium alloy case 10, a mounting block 20, and a connector 30. By embedding the mounting block 20 on the magnesium alloy case 10 and providing the mounting hole 21 on the surface of the mounting block 20 exposed outside the magnesium alloy case 10, the communication device fixes the communication device at a predetermined position by connecting the mounting hole 21 with the connector. On the one hand, the connecting piece of the connecting mounting hole 21 is usually a stainless steel part, and the mounting block 20 can avoid the stainless steel part from directly contacting with the magnesium alloy box body 10, so that electrochemical corrosion between the magnesium alloy box body 10 and the stainless steel part can be prevented, and further, the magnesium alloy box body 10 is prevented from being corroded and damaged, thereby being beneficial to improving the corrosion resistance of the shell of the communication equipment. On the other hand, the communication equipment is frequently disassembled and assembled, only the mounting block 20 is worn, but the protective layer on the surface of the magnesium alloy box body 10 is not worn, so that the integrity of the protective layer on the surface of the magnesium alloy box body 10 is ensured, and the corrosion of the magnesium alloy box body 10 caused by the damage of the protective layer on the surface of the magnesium alloy box body 10 is avoided, thereby being beneficial to improving the corrosion resistance of the magnesium alloy box body 10.

The connector 30 is usually a stainless steel connector, and the sealant accommodated in the first adhesive dispensing groove 14 can isolate the contact area between the magnesium alloy case 10 and the connector 30 from air, so that electrochemical corrosion between the magnesium alloy case 10 and the connector 30 can be prevented, and further, the magnesium alloy case 10 is prevented from being corroded and damaged, which is beneficial to improving the corrosion resistance of the housing of the communication device.
Optionally, the mounting block 20 may be an aluminum block, where the aluminum block can avoid the stainless steel part from directly contacting the magnesium alloy box 10, so as to prevent electrochemical corrosion between the magnesium alloy box 10 and the stainless steel part, further prevent the magnesium alloy box 10 from being damaged by corrosion, and facilitate improving the reliability of the magnesium alloy box 10, and simultaneously facilitate prolonging the service life of the magnesium alloy box 10.
Optionally, the mounting block 20 may be embedded on the magnesium alloy case 10 in an interference fit manner, so as to improve the reliability and connection strength of the embedding of the mounting block 20 on the magnesium alloy case 10. It will be appreciated that the wall thickness of the magnesium alloy case 10 around the location where the mounting block 20 is embedded is large enough to withstand the stresses caused by the embedding of the mounting block 20, thereby ensuring that the strength of the magnesium alloy case 10 meets the requirements.
Further, an adhesive may be coated on the outer surface of the mounting block 20, or an adhesive may be coated in a recess of the magnesium alloy case 10 for embedding the mounting block 20, so that the mounting block 20 is embedded on the magnesium alloy case 10 and can be adhered to the magnesium alloy case 10, thereby improving the reliability and connection strength of the embedding of the mounting block 20 on the magnesium alloy case 10.
Alternatively, the mounting hole 21 provided on the mounting block 20 may be a threaded mounting hole, which facilitates the mounting and dismounting of the communication device, thereby facilitating the maintenance and replacement of the communication device. Of course, the mounting hole 21 provided on the mounting block 20 may be a clamping hole so as to clamp and fix the communication device at a predetermined position through the clamping hole.
