Document Type and Number:
WIPO Patent Application WO/2023/019923
Kind Code:
A1
Abstract:
The present invention relates to the technical field of communication devices, and in particular, to a combined power divider convenient to overhaul, which comprises a housing, a circuit board, and an overhauling module. The housing comprises an upper housing and a lower housing; the upper housing and the lower housing are fixedly connected to each other by means of bolts; an accommodating cavity is formed in the side of the upper housing close to the lower housing; mounting holes which are uniformly distributed are fixedly connected to the side of the lower housing close to the upper housing. According to the present invention, by providing a test groove and test probes, an internal circuit can be tested only by opening a sealing plate during troubleshooting, such that the test process is effectively made to be more convenient and rapid, the troubleshooting rate is effectively enhanced; meanwhile, the probability of damage to the circuit board in the overhauling process can be reduced, such that the overhauling work can be quite conveniently performed; and meanwhile, the circuit board is fixedly connected to the lower housing, and after the upper housing is separated from the lower housing, the circuit board can be directly and completely exposed, such that components on the circuit board can be conveniently replaced and repaired.
