Definitions
- the present invention relates generally connection boxes for coaxial cables intended for the distribution of high frequency signals, and, more especially television signals.
- the present invention relates to a housing of connection meeting this goal.
- connection box is characterized by the characteristics of claim 1.
- the outer casing of the connection box ensures by itself the shielding necessary ; it also ensures by itself the mass of the assembly, and in particular that of the cable shield coaxial arrival.
- the piece of insulating material provided according to the invention downstream of the connection terminal advantageously reconstructs around the stripped part of the core of the incoming coaxial cable, an insulating sheath, which, substantially in connection with the dielectric part of this cable coaxial arrival, is favorable for good continuity of impedance for the whole, and, therefore, to a good adaptation impedance of the starting coaxial cable with respect to the cable coaxial arrival.
- the head of the clamping screw of the connection terminal which is in practice metallic, intervenes friction in a chimney belonging to the envelope external.
- connection 10 As illustrated in Figure 1, the housing of connection 10 according to the invention is intended to allow the connection, to an incoming coaxial cable 11, of a cable starting coaxial 12, for high signal distribution frequency, and more specifically, of television signals.
- the incoming coaxial cable 11 comprises, successively, from the inside to the outside, a central core 13, which is metallic, an insulating sheath 14 internal, which forms a dielectric, a metallic braid 15 intermediate, which forms a shield, and an insulating sheath 16 external, which ensures the protection of the whole.
- the starting coaxial cable 12 has a constitution identical.
- connection box 10 comprises, overall, an outer envelope 18, which forms a shielding, and which has, on the one hand, an input 20, for the engagement of the incoming coaxial cable 11, and, on the other hand, an output 21, for plugging in the starting coaxial cable 12.
- Input 20 allows connection of the enclosure external 18 to the shield of the incoming coaxial cable 11, that is to say to its metal braid 15, this being duly returned as a thermowell for this purpose on the outer insulating sheath 16 after being naked.
- the axis of this entry 20 extends obliquely to that of the exit 21.
- exit 21 includes, so classic, a pin 22, metallic, in the axis of a socket 23, also metallic, for cooperation with a nozzle 24 which is provided, also conventionally, at its end, the incoming coaxial cable 11, with, between pin 22 and the socket 23, a mass of insulating material 25.
- the socket 23 of the outlet 21 is duly connected to the outer casing 18.
- connection terminal 26 for the connection of the central core 13 of the incoming coaxial cable 11.
- this connection terminal 26 comprises a seat 27, metallic, which, disposed substantially in the axis of the entrance 20, is intended to receive this soul central 13, and which is connected to pin 22 of the output 21, and a clamping screw 28, which, according to arrangements described in more detail later, is accessible from outside.
- the seat 27 is in V.
- a flange 29 having a V-shaped recess, the concavity of which is facing the clamping screw 28, and the edge of which is in practice inclined with respect to the axis thereof, being substantially in alignment with the axis of entry 20.
- the seat 27 is also integral with pin 22 of the outlet 21.
- the flange 29 which forms it constitutes one of the wings of a square piece 30 of which the other wing 31 has pin 22 on its back.
- a piece of insulating material 32 downstream of the seat 27 relative to the inlet 20, a piece of insulating material 32, which, in the extension of this seat 27, forms a housing 34 for the end of the core central 13 of the incoming coaxial cable 11, this part in insulating material 32 comprising, for the definition of this housing 34, a base 35, fixed, and a cover 36, movable, on which bears, in practice, the clamping screw 28, by its was 37.
- the part in insulating material 32 is attached to the seat 27, and, more specifically, the flange 29 forming it.
- the square part 30 is recessed on the surface as a whole by its wing 31.
- the cover 36 of the piece of insulating material 32 is articulated transversely to its base 35 on the side thereof opposite the seat 27, and it is in practice in one piece with this base 35.
- the base 35 forms, laterally, two flanges 38, which frame the flange 29 forming the seat 27, and between which struggles, for its guidance, the cover 36.
- the housing 34 formed by the piece of insulating material 32 thus has only one access, that which, facing entrance 20, allows the introduction of the soul control unit 13 of the incoming coaxial cable 11.
- the screw clamp 28 is metallic, and for the continuity of the shielding formed by the outer casing 18, its head 40 acts at friction in a chimney 41 belonging to this envelope external 18.
- the barrel 37 of this clamping screw 28 is in screw connection with a socket 43, which, belonging also to the outer casing 18, protrudes from the internal surface thereof, in the axis of the chimney 41, and directly above the cover 36 of the piece of insulating material 32.
- the outer envelope 18 is, for example, metal.
- this outer envelope 18 is in two parts 18A, 18B, namely, a part 18A, which by itself forms the socket 43 provided for the clamping screw 28 of the connection terminal 26, and a part 18B, which in itself forms the socket 23 of the outlet 21, and preferably these two parts 18A, 18B are duly joined together, for example by means of screwing or latching means not visible on the figures.
- parts 18A, 18B of the outer shell 18 also form, jointly, at the entrance 20, a cable clamp 44, for tightening the incoming coaxial cable 11.
- the cover 36 of the workpiece insulator 32 comes under the action of the clamping screw 28, completely enclose in the housing 34 provided for this purpose the end of the central core 13 of the incoming coaxial cable 11.
- this soul control unit 13 is duly connected to seat 27, and therefore duly connected by it to pin 22 of output 21.
