Definitions
- the invention relates to a coaxial connector with an inner conductor, an outer conductor and a surge protector with a ground inductance and a Capacitor, the capacitor being connected in series with the inner conductor and has a first capacitor plate, which with a first inner conductor an input of the coaxial connector is connected, and a second capacitor plate which has a second inner conductor of an output of the coaxial connector is connected, according to the preamble of claim 1.
- a coaxial connector with lightning protection is known in which a meandering coil connects the inner conductor to the outer conductor.
- the coil extends radially from the inner conductor outwards to the outer conductor and closes low frequency currents, such as due to Lightning strikes, short to ground.
- high-frequency currents are not discharged via the coil, but pass through the inner conductor in the axial direction.
- the inner conductor with a capacitor fitted. This allows high-frequency currents to pass and blocks low-frequency ones Currents due to residual voltages when a lightning strike is derived over the coil. With this arrangement there are therefore undesirable voltage shocks derived to ground without the transmission properties of the coaxial connector noticeable for high frequency.
- the energy for example A lightning strike is radial over the meandering Coil derived by mass.
- this known arrangement has the disadvantage that the manufacture of the meandering coil is difficult and expensive.
- There is also a corresponding force on the meandering Coil if current flows through it when dissipating energy, whereby the force deforms the coil and the greater the current flow, the greater it is is. Due to the limited mechanical strength of the meandering Coil, the current transmission capacity is limited due to a mechanical Breakage of the coil leads to a malfunction of the surge protection.
- GB 21 94 394 A is a coaxial connector with integrated electrical Circuit known.
- a PI filter is applied to a circuit board.
- An axial coil is arranged in a recess of the printed circuit board, the ends of which are each connected to ground and on the PCB attached capacitor.
- the invention has for its object to provide a coaxial connector of the above. kind to improve manufacturing and assembly.
- the inductance is designed as an axial coil and is arranged coaxially to the inner conductor, with a first end of the axial coil is connected to the first capacitor plate and a second, the capacitor opposite end of the axial coil at an axially towards the entrance of the coaxial connector spaced point is connected to the outer conductor.
- the axial coil has a dielectric Base body on which coil windings made of a wire made of conductive Material are applied.
- the axial coil and the first capacitor plate in one piece from a tube made of conductive on one side Material formed, the first capacitor plate on the closed side is formed and further the tube between the closed Side and an open side a helical around a pipe wall extending slot, which the tube wall in corresponding coil turns divides into an axial coil.
- Easier installation and cost-effective production can be achieved by that the first inner conductor is formed in one piece with the first capacitor plate is.
- the first end of the axial coil is expediently in the region of an outer one Peripheral edge of the first capacitor plate electrically connected to this.
- the first preferred embodiment of an inventive Coaxial connector with surge protection includes an input 10, an output 12, a first inner conductor 14 connected to the input 10, a second inner conductor 16 connected to the output 12 and an outer conductor 18.
- overvoltage protection is a capacitor 20 with one first inner conductor 14 connected first capacitor plate 22 and one with the second inner conductor 16 connected second capacitor plate 24 is provided.
- the overvoltage protection also includes an inductor, which is in the form of a Helix coil 26 starting from the first capacitor plate 22 in the direction of the input 10 coaxially surrounds the first inner conductor 14.
- a first end 28 of the helical coil 26 is with the first capacitor plate 22 adjacent to its outer periphery electrically connected.
- a second, facing away from the capacitor 20 End 30 of helical coil 26 is electrically connected to outer conductor 18.
- the Helix coil 26 is pushed onto a tubular dielectric 32, which of the first inner conductor 14 is held and sets a desired impedance.
- the helical coil is designed such that it is between the first and the second end does not change its diameter, but essentially in extends in the axial direction.
- the helical coil forms a choke, so that such currents do not flow to ground via the helical coil, but from the first inner conductor 14 via the capacitor 20 to the second inner conductor 16 and thus be transmitted to output 12.
- the first capacitor plate 22 and the helical coil 26 are integral from a closed at one end Tube 34 made.
- the first capacitor plate 22 is, for example, through Twisting off part of the circumference of the tube 34 at its closed end educated.
- the first inner conductor 14 is screwed, for example, into the first capacitor plate 22 or integrally formed with this.
- the inductance in the form of the helical coil is special simple, fast, inexpensive and in series or mass production manufacture. All that is required is a corresponding milling / turning operation To perform pipe blanks.
