Embodiment 1

[0043] like Figure 1 to Figure 3 As shown, the comprehensive gateway device supporting HPLC communication includes a lower box body 11 and an upper cover body 12 installed on the lower box body 11, a square circuit board 18 is installed in the lower box body 11, and a HPLC is fixed in the middle of the circuit board 18 Communication module 20 . One side of the upper cover body 12 is provided with a display screen and an indicator light, and a first port 14, a second port 15 and a third port 16 are sequentially opened along the length direction on the side wall of the lower box body 11, which is similar to the indicator light, and the HPLC The communication module 20 is connected to the first port 14 through a connecting wire. The side wall is provided with an extension plate 21 extending upward. Correspondingly, a corresponding side wall of the upper cover 12 is provided with an adapter slot 22 which is adapted to fit with the extension plate 21, which is a comprehensive gat...

Embodiment 2

[0054] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the elastic component is an elastic telescopic rod member 25, one end of the elastic telescopic rod member 25 is hinged on the positioning post 19, and the other end is hinged on the buffer plate 28, and the elastic telescopic rod member 25 is hinged on the buffer plate 28. The rod 25 includes a first telescopic piece and a second telescopic piece that are inserted into each other, and a spring is provided between the first telescopic piece and the second telescopic piece. In this embodiment, the elastic telescopic rod can be assembled on the positioning column and the buffer plate through a spherical hinge; or, assembled through a universal hinge. In other embodiments, the elastic component is a spring, one end of the spring is fixed on the positioning post, and the other end is fixed on the buffer plate. When the spring is a tension spring, the circuit board that is impacted by the biasing...

Embodiment 3

[0056] The difference between this embodiment and Embodiment 1 is that: in Embodiment 1, the positioning columns 19 are provided with lugs 30, the circuit board 18 is pressed against the lugs 30 by the nut sleeves 24; the elastic telescopic rods 25 are hinged to the corresponding On the ear plate 30 of the positioning column 19, at this time, the hinge position of the buffer plate 28 and the elastic telescopic rod 25 is lower than the hinge position of the elastic telescopic rod 25 and the positioning column 19, and the circuit board 18 corresponds to the telescopic rod when the eccentric load is applied. 27 pieces stretch for cushioning. In this embodiment, the positioning column is provided with a lug plate, the elastic telescopic rod is hinged on the lug plate corresponding to the positioning column, the positioning column is provided with an upward annular step above the lug plate, and the circuit board is pressed against the ring plate. on the steps. At this time, the hi...

Abstract

The invention relates to a gateway device, in particular to a comprehensive gateway device supporting HPLC (High Performance Liquid Chromatography) communication, and particularly relates to a buffer structure of a circuit board in a gateway. The comprehensive gateway device supporting HPLC communication comprises a lower box body and an upper cover body installed on the lower box body, a circuit board is installed in an inner cavity of the lower box body, an HPLC communication module is fixed to the circuit board, at least three positioning columns arranged at intervals are arranged on the lower box body, and the circuit board is arranged on the positioning columns in a sleeving mode; the nut sleeve is used for being in threaded fit with the positioning column so as to downwards press the circuit board; a buffer piece is arranged between the bottom wall of the lower box body and the circuit board; the buffer piece comprises a buffer disc positioned below the middle position of the circuit board and a middle elastic piece positioned below the buffer disc; an elastic component is arranged between each positioning column and the buffer disc, one end of each elastic component is connected to the corresponding positioning column, the other end of each elastic component is connected to the buffer disc, and when the circuit board is subjected to unbalance loading force, the elastic component on the corresponding side elastically deforms to buffer the circuit board.

Description

technical field [0001] The invention relates to a gateway device, in particular to a buffer structure of a circuit board in a gateway. Background technique [0002] With the rapid development of power grid technology, a large number of IoT sensing and monitoring equipment are connected to the power grid. Due to the lack of unified specifications and management, different equipment brands use their own communication protocols. The huge number of devices and different device protocols have caused great inconvenience to the unified use of the master station for device data collection and management. The relay communication device that can collect and manage the sensor devices and then report the data to the master station uniformly, the gateway, came into being. pregnancy. [0003] For the current comprehensive gateway technology, the gateway device includes a lower box body and an upper cover body mounted on the lower box body. The edge position of the circuit board is usuall...
