Waterproof PCB board with waterproof joint chair

Technical Field

The utility model belongs to PCB board field of making, in particular to PCB board with waterproof function.

Background

A PCB, i.e., a Printed Circuit Board (Printed Circuit Board), plays an important role in electronic devices of today, and is a support for each component in the electronic devices, and is also a carrier for electrically interconnecting electronic components. The PCB board in the electronic device is usually a complete board which has been soldered with corresponding electronic components and can be directly put into use.

The PCB applied to specific electronic equipment often has a certain level of waterproof requirement according to different specific application scenes, and taking the PCB correspondingly arranged on an outdoor performance lamp as an example, the PCB is printed with a circuit of the performance lamp and correspondingly welded with a specified electronic component and is used for controlling specific contents related to real-time working states such as starting and stopping, brightness, color temperature and the like of the performance lamp, and the guarantee that the normal work of the PCB is an important precondition for guaranteeing the normal work of the whole performance lamp. Meanwhile, because the performance lamp needs to be exposed in the outdoor environment all the time, wind, frost, rain, snow, fog, haze and the like in the outdoor environment all affect the PCB, and if the performance lamp is soaked by rainwater, the danger of short circuit exists between the two electronic components which are originally insulated from each other on the PCB; if the PCB is infected by sand wind, the PCB is possibly poor in contact with certain electronic components due to sand accumulation, and under the condition, the PCB is difficult to ensure to keep stable operation for a long time, and the PCB is difficult to continuously fulfill the function of performing the real-time working state of the lamp.

In order to protect the PCB and isolate the PCB from the external environment, a stable and reliable working environment is created for the PCB, and a special housing is additionally disposed on the PCB in the prior art, so that the housing accommodates the PCB to isolate the PCB from the external environment. However, it should be noted that it is difficult to obtain good waterproof and dustproof effects for the housing due to factors such as the structural configuration, the forming effect, and the assembling precision of the housing. On the other hand, the PCB board disposed in the electronic device cannot be isolated, and in most cases, the PCB board needs to be cascaded with the electronic devices in front and rear stages thereof by a physical circuit, and once the circuit needs to be connected or led out, the housing must be correspondingly provided with an opening to allow the circuit to enter and exit, and the opening will also destroy the sealed environment inside the housing, thereby providing a new challenge to the water and dust prevention of the PCB board. Moreover, if a certain PCB disposed in the electronic device fails, an operator must open the housing and then take out or detach the PCB to inspect or repair the PCB, and once the PCB needs to be replaced, the PCB to be replaced and the original PCB must have the same form, otherwise the operator must replace the PCB with a new housing to provide a strict and reliable waterproof measure for the PCB, which brings inconvenience to the later maintenance of the device.
