Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of communication equipment, in particular to a kind of waterproof rainproof communication equipment. BACKGROUND

[0002] Current communication equipment has the following deficiencies in actual use: product is not rainproof, cannot be used outdoors, and overall cost is higher.

[0003] The existing communication equipment protection level is not high, and this defect causes it to be unable to be normally used in outdoor environment. In many practical application scenarios, for example, the outdoor centralized installation area of the intelligent gas meter of city, the outdoor distribution point of water meter of large industrial park and the case that some distributed energy metering facilities are located outdoors, since the communication equipment does not have the function of preventing rainwater, once encountering rainy weather, rainwater is easy to invade the inside of the equipment, thereby causing a series of faults such as short circuit of the equipment and damage of components, which not only causes the transmission of metering data to be interrupted, affects real-time collection and monitoring of data, but also greatly increases the maintenance cost and maintenance frequency of the equipment, and seriously reduces the stability and reliability of the entire metering system.

[0004] Therefore, how to improve the protection performance of the communication equipment and reduce the cost has become a problem to be solved by practitioners in the same industry. CONTENT OF THE UTILITY MODEL

[0005] To solve the above problems, the utility model provides a kind of communication equipment with electric meter, including USB mouth, communication port, upper shell and keyboard, upper shell and display transparent window are welded by ultrasonic, upper shell and bottom shell are welded by ultrasonic, so that the shell of whole equipment forms a solid and well-sealed overall structure. There is a protrusion on the rib structure of upper shell, and a groove structure is provided on the keyboard. The upper shell and the keyboard are interference fit through the protrusion and the groove structure, which not only ensures the stability of the keyboard during operation, but also achieves waterproof and sealing effect. Even if water enters the keyboard, it will be blocked by the interference fit of the protrusion and the groove structure, effectively preventing water from seeping into the inside of the equipment from the gap of the keyboard, and avoiding damage to electronic components. A USB sealing plug is provided at the USB port. When the USB port is idle, the sealing plug can tightly fit the USB port, greatly improving the waterproof performance.

[0006] A communication port sealing plug is provided at the communication port. Preferably, the communication port sealing plug has a through hole, and the communication line can be inserted into the hole and connected with the communication terminal. The communication line and the communication terminal are fastened through the fastening port. This design facilitates the access of the communication line and can tightly wrap the communication line using the elastic force of the sealing plug after the communication line is accessed, reducing the gap. A fastening port sealing plug is provided at the fastening port, further strengthening the sealing protection of the communication port.

[0007] The bottom shell is internally provided with a support column, and an assembled printed circuit board (PCBA) is further arranged between the support column and the keyboard.

[0008] The bottom shell is further provided with a hanging clasp, facilitating installation and fixation of the device.

[0009] The utility model discloses the advantages are: whole structure is stable, supports IP54 protection level, and production cost is low. BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 2 A sectional view of a communication device for communicating with an electric meter. DETAILED DESCRIPTION

[0012] As shown in Figure 1 and Figure 2 , a communication device for communicating with an electric meter includes an upper shell 1, a bottom shell 2, a display window transparent sheet 3, a keyboard 4, a USB sealing plug 5, a communication port sealing plug 6 and a communication terminal fastening port sealing plug 7, a hanging clasp 8 and a printed circuit board 9. The upper shell 1 and the display window transparent sheet 3 are welded together by ultrasonic waves, and the content of the liquid crystal screen can be displayed through the display window transparent sheet 3. The upper shell 1 and the bottom shell 2 are welded together by ultrasonic waves. The keyboard 4 is provided with a groove structure 41, and the upper shell 1 is provided with a protrusion 11 on the rib structure. After assembly with the keyboard 4, interference fit is realized, thereby achieving waterproof sealing effect. The USB port is provided with a USB sealing plug 5. The communication port is provided with a communication port sealing plug 6, and the communication port sealing plug 6 is provided with a through hole 61. The communication line can be inserted into the hole and connected with the terminal, and then the communication line and the terminal are fastened through the communication terminal fastening port. This design makes the communication line tightly wrapped by the elastic force of the sealing plug 6 after being connected, thereby reducing the gap. The communication terminal fastening port is provided with a communication terminal fastening port sealing plug 7. The bottom shell 2 is provided with a hanging clasp 8, and the hanging clasp 8 is not communicated with the inside of the shell, which does not affect the overall protection level.

[0013] The bottom shell 2 is internally provided with a support column, and an assembled printed circuit board 9 (PCBA) is tightly pressed to the upper shell 1 and the keyboard 4 through the support column, thereby increasing the stability of the keyboard 4 and the sealing property at the keyboard 4. The assembled printed circuit board 9 and the keyboard 4 are provided with switches for activating the keyboard at the opposite positions. One of the implementation manners of the switches is that the keyboard 4 is provided with carbon particles at the bottom, and the carbon particles can be contacted with contacts on the assembled printed circuit board 9 by pressing the keyboard 4, thereby making the contacts electrified to activate the keyboard 4.

[0014] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
