The present invention relates generally to an antenna module fabrication method for wireless electronic devices, and more particularly to an antenna module with an assembly connection between the antenna and assembly base.
The signal transmitting and receiving functions of wireless electronic product must be done by antennas to reach an expected effect. The antenna for the traditional wireless electronic product looks protruding on the outside, and it is usually extended to the designated circuit board on the inside. However, with today's wireless electronic product being thin and short, the style and fabrication method for a traditional antenna is outdated, especially with the many handheld or portable electronic products, such as PDA, notebook computers, handheld wireless game consoles or other portable wireless electronic devices. When the size of the electronic products has become smaller and thinner, the traditional antenna that protrudes will look too awkward, and the protruding end of the antenna is not convenient for the electronic products to be carried in the pocket. Moreover, because the wireless electronic devices become smaller, the space inside is very limited. If the antenna is connected electrically by the wire to the circuit board inside the machine, it will cause the wire allocation inside the devices to be more and more complicated.
Thus, to overcome the aforementioned problems of the prior art, it would be an advancement in the art to provide an improved structure that can significantly improve the efficacy.
To this end, the inventor has provided the present invention of practicability after deliberate design and evaluation based on years of experience in the production, development and design of related products.
Because of the characteristics of the antenna 10 being small and thin, its shape is easy to be changed by pressure or outer force, and the performance of the signal transmitting and receiving is greatly affected thereby. After assembling the assembly base 20 and the antenna, the support and reinforcement of the assembly base 20 makes the antenna 10 hard to change shape. During the production of assembling the circuit board, the reinforcement of the assembly base 20 prevents the antenna 10 from changing shapes. Therefore, the assembling production of the antenna 10 and circuit board 50 becomes easier, and largely reduces the defective rate and cost, which meets the economical benefit.
The antenna and the circuit board 50 of the present invention can be connected directly by inserting the protruding footing 25 that is on the bottom of the assembly base 20 into the insert hole 51 on the circuit board 50, and by connecting the two bent edges 1112 of the antenna 10 to the designated area on the circuit board 50. Therefore, the antenna 10 and the circuit board 50 is connected electronically; under the circumstances, the indirect electrical connection from the wire and circuit board 50 is not needed. The special structure of the antenna 10 and assembly base 20 of the present invention can use surface mount technology to connect to the circuit board, which can improve the production speed and the quality. Therefore, the present invention meets the demand of the wireless electronic devices being small and thin, and the antenna module of the present invention becomes better in resolving the issues created from the conventional wireless electronic device that has a protruding antenna. The antenna module of the present invention does not need extra wire to connect circuit board 50 in the limited space inside the wireless electronics to achieve the best signal transmitting and receiving effect, and it meets industrial practicability such as easy assembly and not taking too much room.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.
As shown in
The antenna 10 is a long metal plate. One end of the antenna has two bent edges 1112 that are spaced and shaped almost the same, and the middle of the antenna 10 forms a positioning part 13 that protrudes to one side. The antenna's 10 long plate has holes 14 that are spaced apart. The assembly base 20 is a long block that is made of insulation material. One of its ends has two spaced concave edges 2122 for the two bent edges 1112 of the antenna 10 to set in, and, in the middle of the assembly base 20, has an oblique slot 23 for the positioning part 13 that is located in the middle of the antenna to set in, and, on the other side of the assembly base 20, has protruding columns 24 for the through holes 14 of the antenna to go through. By the design of the above-mentioned parts, the antenna 10 and the assembly base 20 can be connected as one piece.
By revealing the two embodiments mentioned above, it proves that the antenna and assembly base of the present invention can indeed be connected as one piece, and the assembly of the parts can be very diversified. At least the above-mentioned embodiments have revealed the positioning methods such as holes and columns, inserting and locking. Of course, the antenna 10 and the assembly base 20 can be glued as one piece; and the antenna 10 and the assembly base 20 can be connected as one piece by molding.
The description of the antenna module fabrication of the present invention is as follows:
a) make an antenna and an assembly base separately, and make corresponding positioning parts on the antenna and assembly base; and
b) take the positioning parts mentioned above, and connect the antenna and the assembly base as one to make the antenna module.
As for assembling the assembly base to the circuit board as mentioned in the first embodiment,
An antenna module and circuit board fabrication method for a wireless electronic device has an antenna 10 and an assembly base 20, a corresponding positioning part being placed thereon. By coordinating the positioning parts 13 mentioned above to make the antenna module that is made of an antenna 10 and an assembly base 20, the two bent edges 1112 of the antenna 10 are located on the outside of the assembly base 20. The embodiment of the present invention mainly is to remove the protruding footing 25 that is on one side of the assembly base 20, and the insert hole 51 on the circuit board 50, and to connect the antenna module to the circuit board by the surface mount technology.
An antenna module fabrication method for wireless electronic device, includes: setting up an antenna; placing the antenna into the mold; injecting the plasticity material into the mold to form an assembly base; forming a composite of the antenna into one piece to form a one-piece antenna module; and connecting the antenna module to the circuit board by the surface mount technology.
