Description
Technical Field
The invention belongs to a radio frequency device of a satellite receiver, and particularly relates to a simple anti-loosening device of an SMA connector.
Background
In recent years, with the popularization of multi-channel anti-interference technology of satellite receivers, more and more radio frequency connectors are used in the satellite receivers. The reliability of the connection from the vehicle to the missile-borne radio frequency connector directly affects the stability performance of the product. SMA connectors are most widely used in practice.
Conventional SMA connectors do not have a locking measure. Generally, glue is added for fixing and a steel wire is fixed for ensuring the connection reliability. However, the glue adding and fixing mode is difficult to disassemble, and meanwhile, the glue bonding mode can bring redundancy and hidden danger of insulation of a contact part. Traditional steel wire is fixed, and the radial edge of SMA plug is punched and is fixed with the steel wire of the hole penetration at the bottom of the flange of the butt-jointed SMA socket. Because the product integration level is higher, SMA connector volume itself is also less, and the steel wire is difficult to penetrate, and the operation degree of difficulty is great, needs double operation.
Since onboard equipment requires long-term stability to operate, long-term transport vibration is a significant challenge for spin-on-screw connected SMA connectors. Meanwhile, in order to facilitate field maintenance and test of the vehicle-mounted equipment, the convenient and reliable anti-loosening design of the SMA connector is considered.
Disclosure of Invention
The invention aims to provide a simple anti-loosening device for an SMA connector, which can solve the problem that the traditional SMA connector is not convenient to loosen.
The invention is realized in such a way that the simple anti-loosening device for the SMA connector comprises a steel wire through hole, a screw with the steel wire through hole, a cable end connector and a receiver end connector, wherein the receiver end connector is provided with the cable end connector, the cable end connector is provided with the steel wire through hole, and the lower end of the cable end connector is connected with the screw with the steel wire through hole.
The cable end connector is provided with a plurality of steel wire through holes.
The lower end of the cable end connector is connected with a plurality of screws with steel wire penetrating holes.
The invention has the advantages that based on the traditional SMA connector, the position of the steel wire fixing hole is adjusted, the method for preventing the SMA from loosening by adopting the mode of perforating the side surface, fixing the screw and the fixing hole is provided, the loosening prevention effect is good, and the installation is convenient. The product reliability is improved and the product manufacturability is improved.
Drawings
Fig. 1 is a simple anti-loosening device for an SMA connector according to the present invention.
In the figure, 1 is a steel wire hole, 2 is a screw with the steel wire hole, 3 is a cable end connector, and 4 is a receiver end connector.
Detailed Description
The invention is described in detail below with reference to the following figures and specific embodiments:
the invention provides a method for preventing SMA from loosening by adopting a mode of perforating a side surface, fixing a screw and a fixing hole based on a traditional SMA connector and adjusting the position of a steel wire fixing hole, and the method has a good loosening prevention effect and is convenient to install. The product reliability is improved and the product manufacturability is improved.
The simple SMA connector anti-loosening device according to the present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1, a simple anti-loosening device for SMA connector includes a steel wire hole 1, a screw 2 with a steel wire hole, a cable end connector 3 and a receiver end connector 4, wherein the receiver end connector 4 is connected with the cable end connector 3, the cable end connector 3 is provided with a plurality of steel wire holes 1, and the lower end of the cable end connector 3 is connected with a plurality of screws 2 with steel wire holes.
After the connector is in butt joint and screwed down, the steel wire penetrates through the opening on the side face of the cable end connector, the steel wire conveniently penetrates through the opening on the screw and is screwed down, and the purpose of preventing looseness is achieved very quickly.
