Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a television terminal to which a coaxial cable or feeder line for transmitting VHF and U-HF radio waves received by an antenna to a television is connected.

5 Conventionally, this type of TV terminal has a resistance value of 75 Ω, as shown in Figures 1 and 2, and a coaxial cable, which is less susceptible to external influences, has a resistance value of, for example, 75Ω, as shown in Figure 1.
The outer conductor (not shown) of the coaxial cable is connected to the 10 terminal 2, which consists of a terminal plate A, a screw port, and a presser body C, and the inner conductor (not shown) is connected to a terminal plate, which consists of a terminal plate E and a screw. For example, a feeder wire that has a resistance value of 300Ω and is susceptible to external influences but is inexpensive is connected to the terminal board by twisting each core wire (not shown) as shown in Figure 2. 15
It continues.

Therefore, two types of TV terminals are required: one dedicated to coaxial cables and one dedicated to feeder lines. This invention has been made in view of the above circumstances, and the first object of the invention is to provide a television terminal that can be used for both coaxial cables and feeder lines, and that allows easy connection of coaxial cables. It is on offer.

A second object of the invention is to provide a television terminal that achieves the object of the first invention and is easy to assemble. '5 An embodiment of the present invention will be described below with reference to FIGS. 3 to T.

1 is a container body, which has a pair of through holes 3 separated by a partition wall 2.
and four groups 6 having a window hole 5 on the side of this through hole 3 in the bulging part 4.
are installed consecutively.

7 is a metal fitting, and the box embedded in the construction material has a no.
A protrusion 9 is provided that is engaged with a horizontal hole 8 that is engaged with a claw piece (not shown) of the mounting frame to be fixed, and a protrusion 9 that is engaged with another mounting frame (not shown).

These are for fixing the container body 1 to the mounting frame. 10 is a split terminal, which has an L-shaped terminal 15 having a locking part 11 inserted into a groove 12; a plate 13; a protruding part 14; and a hole 15 through which the locking part 11 passes; It consists of an L-shaped terminal plate 16 which is assembled with the terminal plate 13 by springing the portion 14 and deforming the locking portion 11.

17 is a screw hole, and 18 is a locking protrusion, which prevents the core wire Xa of the feeder wire X from shifting from the terminal plates 16, 16.

Reference numeral 19 denotes a presser body made of resin, which is composed of a circular arc portion 20 and a flat surface 22 having screw holes 21 at both ends thereof.
The outer conductor Ya of the coaxial cable Y or the core wire Xa of the feeder wire X is connected to the split terminal 10 by screwing the bridging screw 23 between the ends of the coaxial cable Y into the screw hole 17 of the split terminal 10.

Reference numeral 24 designates a locking body for connecting the internal conductor Yb of the coaxial cable Y, and has quick connection terminals 26 made up of a pair of spring bodies 25 at both ends, and a notch 27 approximately in the center.

Reference numeral 28 designates an inner lid, in which the projection 29 locks the notch 27, the hole 30 corresponds to the quick-connect terminal 26, the locking body 24 is attached to the recess 31, and one quick-connect terminal 26 is inserted into the window hole. 5 and is fitted into the recess 6 of the container body 1.

The protrusion 32 is sandwiched between the terminal plate 16 and the container body 1, and
3 and the terminal plate 16, the recessed chamber 6 prevents the inner cover 28 from coming off. 33 is a mold hole for molding the protrusion 29.

When connecting the coaxial cable Y, the outer conductor Ya and the inner conductor Yb are exposed and the inner conductor Yb is simply inserted through the hole 30 and connected to the quick connection terminal 26, as shown in FIG.

Next, by screwing the screw 23 into the screw hole 17, the outer conductor Ya is connected to the split terminal 10 and transmits radio waves to the television. 34 is a hole for checking the connection state between the internal conductor Yb and the connection terminal 26.

Further, the coaxial cable Y from the antenna is similarly connected to the quick connection terminal 26 by a screw 35 which is screwed into the screw hole 17 with a screwdriver. Note that the inner cover 28 may be transparent so that the connection state between the internal conductor Yb and the quick connection terminal 26 can be confirmed. Next, when connecting the feeder wires X, as shown in FIG. 7, by exposing the core wires Xa and screwing the screws 23 into the screw holes 17, the core wires Xa are connected to the respective split terminals 10, and It transmits radio waves to.

Further, the feeder line X is also connected from the antenna by a screw 35 that is screwed into the screw hole 17 using a screwdriver. In addition, the resistance value of the coaxial cable Y is 75Ω in the container 1.
If you have built-in equipment to match the impedance of the feeder wire X and the resistance value of 300Ω from the antenna, use coaxial cable Y from the antenna and feeder wire It is also possible to use this combination. As explained above, this invention includes a pair of split terminals 10 that connect the outer conductor Ya of the coaxial cable Y or the core wire Xa of the feeder wire X, a resin presser body 19 that bridges between the split terminals 10, Since it consists of a quick connection terminal 26 that connects the internal conductor Yb of the coaxial cable Y, it can be used for both the coaxial cable Y and the feeder line The conductor Yb can be simply inserted through the hole 20, making it easy to connect the coaxial cable Y. Next, a television terminal can be obtained which can be assembled by the simple operation of fitting the inner lid 28 equipped with the locking body 24 provided with the quick-connect terminals 26 at both ends into the recessed chamber 6 of the container body 1.
