Abstract
The invention aims at providing a shielding case structure for a car audio, which comprises a PCB, a sound receiving module and a sound receiving antenna, wherein the sound receiving module and the sound receiving antenna are both arranged on the PCB; the sound receiving module is arranged right below the sound receiving antenna; the sound receiving module is coated with a shielding case; the shielding case is arranged on the PCB; the shielding case extends upwardly to coat the lower half part of the sound receiving antenna; and the place, close to the sound receiving antenna, on the shielding case is provided with a welding flange. Through lifting the shielding case to the height of the sound receiving antenna, forming of a hardware mold is facilitated; as the place, close to the sound receiving antenna, on the shielding case is provided with the welding flange, welding and grounding with the sound receiving antenna are facilitated; and a ground line is pre-welded on the welding flange, a step of welding the grounding line during an assembly process is saved, thereby improving the production efficiency and reducing a quality risk.
Description
Technical field
The present invention relates to the design and manufaction field of automobile audio, particularly relate to a kind of shielding case structure of automobile audio.
Background technology
The radome of existing automobile audio only shields for radio module, needs to carry out ground connection by the welding of single line bundle.This kind of way needs welding, adds a procedure, because welding needs the time, often becomes the bottleneck of whole piece streamline, has a strong impact on product quality and production efficiency.
For above-mentioned problem, for automobile audio provides novel radiator structure, enhance productivity, reducing quality risk is the problem that prior art needs to solve.
Summary of the invention
For solving the problem, the invention provides a kind of radome new construction of automobile audio, with reach enhance productivity while reduce the object of quality risk.
The object of this invention is to provide a kind of shielding case structure of automobile audio, include pcb board, radio module and reception antenna, described radio module and reception antenna are all arranged on pcb board, and wherein radio module is arranged on immediately below reception antenna; Described radio module is coated with radome, and radome is arranged on pcb board; Described radome upwards extends the latter half enveloping reception antenna; Described radome is provided with close reception antenna place and welds crimp.
Further improvement is: on described welding crimp, prewelding is connected to earth connection by radome and reception antenna ground connection.
Further improvement is: described welding crimp and radome are one.
Further improvement is: between radio module and reception antenna, arrange demarcation strip inside described radome, demarcation strip is arranged on pcb board.
Beneficial effect of the present invention: the present invention is by being raised to the height of reception antenna by radome, be beneficial to hardware dies shaping, and increase a welding crimp at radome near reception antenna place, for welding ground connection with reception antenna, earth connection is that pre-welding is being welded on crimp, thus save the step of the welding earth connection in assembling process, improve production efficiency, also reduce quality risk.
Accompanying drawing explanation
Fig. 1 is side sectional view of the present invention.
Fig. 2 is front view of the present invention.
Wherein: 1-PCB plate, 2-radio module, 3-reception antenna, 4-radome, 5-welds crimp, 6-earth connection, 7-demarcation strip.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
As illustrated in fig. 1 and 2, the present embodiment provides a kind of shielding case structure of automobile audio, include pcb board 1, radio module 2 and reception antenna 3, described radio module 2 and reception antenna 3 are all arranged on pcb board 1, and wherein radio module 2 is arranged on immediately below reception antenna 3; Described radio module 2 is coated with radome 4, and radome 4 is arranged on pcb board 1; Described radome 4 upwards extends the latter half enveloping reception antenna 3; Described radome 4 is provided with close reception antenna place and welds crimp 5.On described welding crimp 5, prewelding is connected to earth connection 6 by radome 4 and reception antenna 3 ground connection.Described welding crimp 5 and radome 4 are one.Between radio module 2 and reception antenna 3, arrange demarcation strip 7 inside described radome 4, demarcation strip 7 is arranged on pcb board 1.
By radome 4 being raised to the height of reception antenna 3, be beneficial to hardware dies shaping, and increase a welding crimp 5 at radome 4 near reception antenna 2 place, for welding ground connection with reception antenna 3, earth connection 6 is that pre-welding is being welded on crimp 5, thus save the step of the welding earth connection 6 in assembling process, improve production efficiency, also reduce quality risk.
