Abstract

(57) [Abstract] [Purpose] The water discharge type connector for connecting cables to outdoor equipment such as LNBs has a simple structure to achieve economic efficiency. [Structure] A screw 2a of a receptacle 2 is screwed into a screw hole 1a of an LNB chassis 1 via an O-ring 5.
The core wire 4a of the cable 4 is the core wire terminal 2d of the receptacle 2.
Is inserted into. The outer wire 4b of the cable 4 is connected to the outer peripheral terminal 2e of the receptacle 2 by covering it. The core wire 4a and the sheath wire 4b of the cable 4 are separated by an insulator 4c. Between the cable 4 and the receptacle 2, the connector 3 that is fitted in the cable in advance is screwed into the receptacle 2 by the screw 3a.
It is screwed to the screw 2b provided on the above through the waterproof O-ring 6. A waterproof O-ring 7 is arranged between the insulating jacket 4 d of the cable 4 and the connector 3. Therefore, the connector 3 can rotate independently of the cable 4 while maintaining waterproofness, and can be easily screwed to the receptacle 2.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a BS / CS converter LNB installed in association with a BS / CS antenna.
The present invention relates to a waterproof LNB output connector having a simple structure used for (low noise block) or the like.

[0002]

2. Description of the Related Art Conventionally, a waterproof connector has been attached to the tip of a cable, and a device such as an LNB chassis is connected to the connected device using a waterproof connector or a waterproof receptacle to ensure waterproofness. An example thereof is shown in FIG. 2 (A) side view and FIG. 2 (B) same sectional view. LN
The connector 23 attached to the tip of the cable 24 is attached to the receptacle 22 attached to the B chassis 21, and the LNB signal is output. The cable 24 is fixed to the central portion 29 of the connector by a connector case 23a, and O-rings 28 and 27 maintain waterproofness between them. The attachment of the receptacle 22 of this connector is screwed at a screw fastening end 30 which is rotatably fitted to the central portion 29 of the connector. A waterproof O-ring 26 is arranged between the screwed end 30 and the receptacle 22. However, in this method, the waterproof connector attached to the cable must use many O-rings as described above in order to ensure waterproofness, which is a complicated structure compared to a normal connector. was there.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to provide a waterproof connector having a simple structure.

[0004]

Means for Solving the Problems A screw for fixing to a chassis such as an LNB or the like at one end, a screw for screwing with a connector at the other end, and a core wire terminal for receiving a cable core wire at a core part and its outer periphery A receptacle having an outer peripheral conductor for receiving a coated conductor of a cable through an insulator, and a core wire terminal and an outer peripheral conductor of the receptacle are connected to the core wire of the cable and the coated conductor, respectively, and from the outer periphery to the other end of the receptacle. A connector for screwing and fixing the cable to the receptacle is provided to connect the cable to a chassis such as LNB.

The cross section including the center of the receptacle at the end portion for connecting the cable of the outer peripheral conductor of the receptacle has a wedge shape.

[0006]

Operation: A screw for fixing to a chassis such as an LNB or the like at one end, a screw for screwing into a connector at the other end, a core wire terminal for receiving a cable core wire at a core portion, and a cable through an insulator around the core wire terminal. A receptacle having an outer peripheral conductor for receiving the covered conductor, and a core wire terminal and an outer peripheral conductor of the receptacle to which the core wire of the cable and the covered conductor are respectively connected, and the outer end of which is screwed to the other end of the receptacle to form the cable. By connecting the cable to the chassis such as LNB etc. by providing a connector for fixing the connector to the receptacle, the cable can be directly connected to the receptacle, and the O-ring between the center part and the screwed end part of the conventional connector is unnecessary. Become.

By making the cross section including the center of the receptacle at the end portion for connecting the cable of the outer peripheral conductor of the receptacle a wedge shape, the receptacle and the cable can be easily and surely connected without the need for other terminals.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The LNB connector according to the present invention will be described in detail below with reference to the drawings. 1A and 1B are a side view and a sectional view, respectively, of an embodiment of an LNB connector according to the present invention. A screw 2a provided at one end of the receptacle 2 is screwed into a screw hole 1a provided by boring a part of the LNB chassis 1 via a waterproof O-ring 5. The core wire 4a of the cable 4 is inserted into the core wire terminal 2d of the receptacle 2 as it is or via a terminal (not shown) for terminal processing. The outer wire 4b of the cable 4 is connected to the outer peripheral terminal 2e of the receptacle 2 by covering it. The tip of the outer peripheral terminal 2e, which is connected to the outer cover wire 4b of the cable 4, may be attached between the receptacle 2 and the connector 3 as a separate element from the receptacle 2. The core wire 4a and the outer wire 4b of the cable 4 are separated by an insulator 4c. Between the cable 4 and the receptacle 2, a connector 3 previously fitted in the cable is screwed with a screw 3a, and a screw 2b provided on the receptacle 2 is fitted with a waterproof O-ring 6.
Screw through. A waterproof O-ring 7 is arranged between the insulating jacket 4 d of the cable 4 and the connector 3. Therefore, the connector 3 can rotate independently of the cable 4 while maintaining waterproofness, and can be easily screwed to the receptacle 2. The core wire terminal 2d and the outer peripheral terminal 2e of the receptacle 2 are insulated by an insulator 2c, and the core wire terminal 2d is LN.
In the B chassis 1, it is connected to a board or the like (not shown) of the BS / CS converter.

The tip of the outer peripheral terminal 2e of the receptacle 2 connected to the outer wire 4b of the cable 4 is a separate element from the receptacle 2 and the connector 2 and the connector 3 as described above.
Although it may be attached between the two, it may be constructed as an integral structure with the receptacle 2. At this time, the outer circumference of the tip is gradually narrowed toward the cable side, and the cross section passing through the center line has a wedge shape, so that the cable jacket can be easily connected.

[0010]

As described above, by connecting the cable directly to the receptacle mounted on the device with the connector for connecting the cable to the LNB and the like, and then fitting the connector from above, the screw is fixed to the connector side. It is possible to construct a cable connector that does not require the ends or O-rings.
Therefore, the structure is simple and economical, and it is easy to ensure waterproofness.
