The foregoing aspects and many of the attendant advantages of this invention will be more readily appreciated as the same becomes better understood by reference to the following detailed description, when taken in conjunction with the accompanying drawings, wherein:
Reference is made to
The coupling device 100 has a housing 1, an isolation component 2 disposed within the housing 1, and a connector 17 disposed on the housing 1. The housing 1 is made of aluminum or aluminum alloy. It can prevent electric power from leaking, as does the conventional isolation chamber. The isolation component 2 is made of bakelite or other appropriate isolation materials.
The housing 1 has a socket 13 at one side, as shown in
The isolation component 2 is fixedly disposed in the socket 13 of the house 1. The isolation component 2 has a chamber 20 formed therein and the chamber 20 has two openings in two sides thereof. The openings are aligned in the direction of the socket 13. A metal plate 21 is attached to the inner wall of the chamber 20 of the isolation component 2 via adhesion. The metal plate 21 has a grounding portion 212 and a connecting portion 211. The connecting portion 211 is used to connect to the connector 17 and the grounding portion 212 is used to connect to the ground.
The connector 17 is disposed at a side of the housing 1 and has an end connecting to the connecting portion 211 of the metal plate 21 and another end connecting to a signal transmission line.
The housing 1 can be formed integrally, as mentioned above, or in combination, as shown in the figures. The combinative housing 1 includes a first shell 11 and a second shell 12 that can be combined together. The inner surfaces of the first shell 11 and the second shell 12 both have indentations 14. Each of the indentations 14 has an enlarged portion 141. The socket 13 is formed by combining the indentations 14. The enlarged portions 141 are located at the front end of the socket 13. Hence, the front end of the socket 13 is larger than the rear end. Since the front end of the socket 13 is larger, the socket 13 can be prevented from contacting the electronic components of the antenna device 300. The rear end of the socket 13 is used for disposition of the isolation component 2. The first shell 11 and the second shell 12 respectively have concave portions 16 for clamping the connector 17. The connecting portion 211 of the metal plate 21 is connected to the connector 17 for transmitting signals. The grounding portion 212 is connected to the housing 1. For combination, the first shell 11 and the second shell 12 respectively have multiple holes 111 and 121. By using multiple fixing components as well as the holes 111 and 121, the first shell 11 and the second shell 12 can be combined together. In this way, the coupling device 100 is formed.
The coupling device 100 is used especially to test plate-shaped antenna devices, such as the antenna device 300 shown in
Reference is made to
In the coupling device 100, the socket 13 of the housing 1 and chamber 20 of the isolation material 2 are formed as slots. Hence, the coupling device 100 is suitable to test the plate-shaped antenna device 300. As shown in the figures mentioned above, when the antenna device 300 is plugged into the socket 13 of the coupling device 100, the distance between the circuit board 3 and the metal plate 21 is very short and the power loss can thus be reduced. In practice, since the shape and size of the socket 13 and the chamber 20 can be designed according to the shape and size of the antenna device 300, an antenna device 300 of any size or shape can be completely plugged into the socket 13 and the chamber 20. Hence, the distance between the circuit board 3 and the metal plate 21 can be further reduced via proper design and the power loss can be further reduced in this way. Moreover, the housing 1 is made of aluminum or aluminum alloy. Hence, it can prevent electric power from leaking, as does the conventional isolation chamber.
