Next, I indicates an electronic circuit element, and in this example, three resistors 28, 28, and 28 constitute a distribution circuit element. .rho. and 29.29 respectively indicate terminal pieces, which are constructed by loosely fitting the resistor lead wire 28a as shown in FIG.

Note that the terminal pieces may be connected by simply sewing the leads 1I 128a together, but in order to further improve the reliability of the electrical connection, it is better to electrically and mechanically connect the lead wires 28a to each other by soldering. Next (fund) is a well-known power supply! (coaxial cable), 3
1 indicates the outer conductor, and 1 indicates the center conductor. It also shows an opening fixing tool, on which a threaded part and a pressing part are formed. Further, this fixture is made of a highly elastic synthetic resin material such as ABS resin.

Next, the assembly procedure of the above structure will be explained. First, the external conductor connection pieces 9 are placed in grooves formed in the holder elements 2a and 2b, respectively. In this case, as is clear from the drawings, the holding part 10 is press-fitted into the inside of the holding part 5. On the other hand, apart from this, each terminal piece 9 of the electronic circuit element
is connected to each terminal piece connector in the plurality of terminal fittings 14. That is, each terminal piece is inserted into the insulating tube 15 through the insertion hole 16, and the pair of clamping pieces ρ, 22 in the terminal piece connecting tool field are inserted.
Insert between. In this case, the presence of the guide row facilitates the insertion. Next, the combined electronic circuit element η and the terminal fitting 14 are connected to one element, for example, 2
In contrast to b, the electronic circuit element I is assembled in such a manner that it is located in the storage space 6 and the terminal fitting 14 is inserted into the inside of the holding part 10 located in the holding part 5. In this case, the terminal fitting 14
Since the outer shape of the insulating cylinder 15 is formed to be slightly larger than the inner shape of the clamping part 10 in the external conductor connection piece 9, the terminal fitting 14 can be placed inside the clamping part 10 by pushing it in with a little force. It is done in the state. Next, the holder element 2a, in which the external conductor connection piece 9 has been installed in advance as described above, is opposed to the holder element 2b, and the element 2a is placed against the element 2b so that the protruding pieces 3 fit into the four parts 4. and join together. As a result, both elements 2a.

2b are connected to each other, and the terminal fitting 14 is clamped and fixed inside the holding part 5 via the clamping part 10.
The movement of the terminal fitting 14 is completely blocked. The above-mentioned work ((Thus, the distributor 1 is completed.

Next, when connecting a power supply line (material) to use the above-mentioned distributor, the terminal of the power supply line (material) without a trench is processed as shown on the left side of FIG. Next, the insulator portion and the center conductor at the terminal are inserted into the attached portion ν of the outer conductor connection piece 9, and the center conductor 32 is further inserted into the pair of clamping pieces of the feeder line connector 19 through the insertion hole 16. Insert between η. Further, at this time, the external conductor 31 can be attached to the outer surface of the attached portion ν. After that, the edge of the screwing part of the fixture field is screwed into the screwing part 7. Then, the external conductor 31 is pressed against the attachment part 12 by the pressing section, and a good electrical connection between the external conductor 31 and the connecting piece 9 is established. The above operations are performed on the three power feed lines to be connected to the distributor 1.

In this state, when a television signal comes in from either feeder, the signal is divided by the electronic circuit element η,
Two other books! It is distributed into lines and sent out individually.

Next, FIG. 6 shows a different embodiment of the present application, and shows an attenuator as an example of an electronic device.

In this attenuator, an attenuation circuit element composed of one resistor 280 is used as the electronic circuit element 27e.

It should be noted that parts that are considered to have the same or equivalent structure as those in the previous figure in terms of function are given the same reference numerals as in the previous figure with an e (alphabeta), and redundant explanations are omitted.

As described above, in the present invention, a plurality of terminal fittings 14 are used, each of which is provided at one end and the other end with a feed line connector 19 and a terminal piece connector (A) that are electrically connected to each other. Therefore, in assembling, in addition to the terminal piece connector of each terminal fitting 14, each terminal piece 2 of the electronic circuit element I? By simply inserting the , it is possible to (1) electrically connect a plurality of feeder line connectors 19 to each other, and (2) electrically interpose the electronic circuit element n between the feeder line connectors 19. It is possible to perform two tasks at the same time, including assembly and assembling with good work efficiency.

Moreover, even if the electrical connections (1) and (2) are made only by insertion as described above, the plurality of terminal fittings I4 are fixed to the phase H by the integrated holder 2, so that the The electrical connection states of (1) and (2) can be made extremely stable, which has the effect of making it possible to manufacture electronic devices that are highly reliable during use.
