Abstract

The invention relates to an antenna amplifier which limits the amount of parts and can reliably fix a receiving-releasing part. The antenna amplifier comprises a base plate having a coaxial connector and a receiving-releasing base plate main body, wherein the main body comprises at least a part of a wall part around the base plate, a support chip which is extended out from the wall part and bent inwards to support the lower surface of the base plate and a tongue piece opposite to the support chip relative to a thickness direction of the base plate. The wall part, the support chip and the tongue piece are integrated by using a metal plate. A part in the wall part corresponding to the coaxial connector is provided with a fixing part for fixing the coaxial connector by using an opening formed by turning up. The tongue piece and the base plate are fixed by a soldering tin.

Description

technical field [0001] The present invention relates to antenna amplifiers. Background technique [0002] Conventionally, in antenna amplifiers, the housing board and the main body of the connector are molded by casting. Figure 5 It is a perspective view showing an example of a conventional antenna amplifier 100 . as it should Figure 5 As shown, the antenna amplifier 100 is provided with a main body 110 and a cover 120 . The main body 110 accommodates the substrate 101 , the connectors 102 a , 102 b mounted on the substrate 101 , and the coaxial connector 103 . Connectors 102a and 102b are connected with cables routed to electronic devices, power supplies, and the like. On the other hand, a coaxial cable routed to the antenna is connected to the coaxial connector 103 . In addition, in order to fix the coaxial connector 103 , the main body 110 is provided with a fixing part 111 covering the periphery of the coaxial connector 103 . After the coaxial connector 103 is inse...
