Description

Technical Field

[0001] The utility model relates to the technical field of laser wind measuring radar, in particular to a double sealing joint structure used for laser wind measuring radar. Background Art

[0002] Existing laser wind radars generally use external fans for heat dissipation, or use built-in fans, and place the fans at the shutters on the side of the device to exhaust the heat inside the device. Since the application scenarios of laser wind radars often need to cope with relatively harsh working environments, such as offshore buoys, boats, airport outdoor, etc., which are often washed by seawater or rainwater, the waterproof performance of the radar shell and internal electrical wiring components is very high to avoid water seepage and leakage affecting the performance of the laser wind radar. The traditional junction box used in the laser wind radar is waterproofed by using electrical connectors with IP67 waterproof performance. The lines and connectors connected to the internal electrical components are waterproofed by the radar shell. Since the radar used at sea is washed by waves for a long time, seawater can easily flow back into the radar from the heat dissipation port. Therefore, the junction box using only waterproof connectors can no longer meet the actual use needs. The seawater that flows back into the interior will also accumulate in the junction box, causing the internal electrical wiring head to be damaged by long-term contact with seawater. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a double-sealed joint structure for a laser wind measuring radar which can effectively prevent water seepage of a junction box caused by water ingress into the radar.

[0004] The technical solution adopted by the utility model is: the utility model includes a junction box body and an upper machine cover plate which are fastened and matched with each other, a sealing gasket is arranged between the junction box body and the upper machine cover plate, a plurality of connector sockets are also arranged on the junction box body, and electrical connectors are connected in the connector sockets, a wiring hole is opened on the upper machine cover plate at a position corresponding to the junction box body, a PCB terminal board is fixedly connected to the position of the wiring hole on the lower end surface of the upper machine cover plate through a clamping plate, and the PCB terminal board covers the entire wiring hole, and at least one circle of waterproof grooves adapted to the PCB terminal board and the clamping plate are arranged on the lower end surface of the upper machine cover plate and / or the top of the junction box body and the matching surface of the PCB terminal board.

[0005] Furthermore, a wiring cavity is provided inside the junction box body, and a sealing groove matched with the sealing gasket is provided at the top. The shape and size of the top opening of the wiring cavity are matched with the PCB terminal board and the clamping plate. After the junction box body and the upper machine cover are assembled, the clamping plate is embedded in the top of the wiring cavity.

[0006] Furthermore, a waterproof gasket is provided between the PCB wiring board and the pressing plate.

[0007] Furthermore, the waterproof groove is opened at the lower end surface of the upper machine cover plate, and the depth is consistent with the thickness of the PCB wiring board.

[0008] Finally, at least one sealing rubber ring is arranged between the electrical connector and the connector socket.

[0009] Compared with the prior art, the beneficial effect of the utility model is as follows: the utility model forms a double-sealed joint structure by setting a layer of waterproof structure between the top of the junction box and the upper machine cover plate, combined with the original waterproof performance of the electrical connector, thereby forming a double waterproof structure inside and outside the radar, greatly improving the waterproof effect of the equipment. Specifically, by opening the wiring hole on the upper machine cover plate, the PCB wiring board originally placed inside the junction box body is fixedly set at the lower end surface of the upper machine cover plate through the clamping plate, covering the wiring hole as a waterproof layer. At this time, the clamping plate is also embedded in the top of the wiring cavity as an end cover, further preventing water from entering the junction box body, and further improving the waterproof effect of the utility model. Therefore, the utility model can effectively avoid water seepage in the junction box due to water entering the radar, and achieve a double waterproof effect from both inside and outside the radar.
