It is sandwiched. The wiring portion 4 has arc-shaped first to third wiring portions 4 arranged in parallel along the bending direction of the intermediate surface 3c.
a to 4c, the conductive wire 7j, and the first to third wiring portions 4

In each of the first to third wiring portions 4a to 4c, electric resistors 5a to 5c, 5d to 5e, 5f to 5i are arranged at intervals, which are conductive lines 7a to 7c, respectively.
They are connected by 7d to 7f and 7g to 7i. On the other hand, on the outer wall portion 3b of the connector 1, the first to third
Conductive lines 7a to 7i and conductive lines 7j of the wiring portions 4a to 4c
The ten open holes 9a to 9j are formed corresponding to the positions. The open holes 9a to 9j reach the conductive wires 7a to 7j from the surface of the outer wall portion 3b of the connector 1,
It is formed in the outer wall portion 3b and opens.

Next, a method of manufacturing the connector 1 of this embodiment will be described. First, the inner wall portion 3a is manufactured by injection molding or the like using the above-mentioned synthetic resin as a raw material. next,
On the outer peripheral surface of the inner wall portion 3a, the electric resistors 5a to 5i and the conductive lines 7a to 7k of the wiring portion 4 are formed as follows.

First, in order to form the conductive lines 7a to 7k,
For example, a conductive material such as silver is made into a powder, and the powder and a binder such as an epoxy resin and a solvent are kneaded into a paste,
This is applied linearly to the outer peripheral surface of the inner wall portion 3a and then dried. The paste is not applied to the portions where the electric resistors 5a to 5i are arranged.

Next, in order to form the electric resistors 5a to 5i, for example, a resistance material such as carbon is made into powder, and the conductive wire 7a is formed.
As in the case of ~ 7k, this powder, a binder such as an epoxy resin, and a solvent are kneaded to form a paste, and the paste is formed at the position where the resistor of the inner wall portion 3a is formed (the paste forming the conductive wire is applied To the conductive wire 7a.
Approximately 7k is applied so as to be connected, and then dried.

Next, the outer wall portion 3b is formed by so-called two-color molding so as to cover the electric resistors 5a to 5i and the conductive wires 7a to 7k on the outer side of the inner wall portion 3a on which the conductive wires 7a to 7k are formed. Form. That is, the conductive lines 7a to 7j
In order to form the open holes 9a to 9j that reach the position, a convex portion is formed in a mold (not shown), and the mold and the inner wall portion 3a are formed.
And an outer wall portion 3b is formed between and.

The connector 1 thus formed is
For example, it is used as follows. As shown in FIG. 4, the power source 41 and the connector 1 are the electric wires 4 extending from the power source 41.
The conductive terminal 45 of No. 3 is inserted into the open hole 9j of the connector 1, and the conductive terminal 45 is connected by contacting the conductive wire 7j of the connector 1. In addition, the power source 41
Is also connected to one input terminal 47a of the electronic component 47. The electric wire 49 connected to the other input terminal 47b of the electronic component 47 is provided with a conductive terminal 51. The conductive terminal 51 is inserted into the open hole 9a of the connector 1 and is in contact with the conductive wire 7a.

Therefore, in this used state, the power supply 41, the electronic component 47 and the connector 1 form the following closed circuit. That is, from the input terminal 47a of the electronic component 47 to the electric resistance 5a via the power supply 41, the electric wire 43, the conductive terminal 45, and the conductive wires 7j and 7k of the connector 1, the conductive wire 7a, the conductive terminal 51, A closed circuit is formed that returns to the input terminal 47b via the electric wire 49. That is, the electronic component 47 is connected in series with the electric resistor 5a in the connector 1 and the power supply 41.

Therefore, as is clear from Ohm's law, since a voltage drop occurs in the electric resistor 5a, the power source 41
The voltage applied to the electronic component 47 is lower than the voltage value of the power supply 41. Next, in the state of FIG. 4, the conductive terminal 51 is pulled out from the open hole 9a, inserted into the open hole 9b, and brought into contact with the conductive wire 7b. Then, in the above-mentioned closed circuit, the electric resistor 5b is added to the electric resistor 5a,
The electronic component 47 is the two electric resistors 5 in the connector 1.
a and 5b are connected in series. Therefore, as compared with the case where the conductive terminal 51 is inserted into the open hole 9a, the resistance value connected in series to the electronic component increases, and the voltage applied to the electronic component 47 can be further reduced.

Similarly, the conductive terminal 51 is opened to the open holes 9c to 9c.
If it is used by inserting it into 9i, the electric resistor 5a,
Similar to the case of 5b, the electric resistors 5c to 5i and the electronic component 47 can be connected in series. With the configuration described above in detail, the connector 1 of this embodiment has the following effects.

In the connector 1 of this embodiment, a plurality of electric resistors 5a to 5i and conductive wires 7a to
7k is arranged, and the wall portion 3 thereof is provided with open holes 9a to 9j reaching the conductive lines 7a to 7j. Therefore, the power source 41, the electronic component 47, and the electric resistors 5a to 5i are connected in series by inserting the conductive terminals 45 and 51 into the open holes 9a to 9j and bringing them into contact with the conductive wires 7a to 7j. Therefore, since a voltage drop occurs in the electric resistors 5a to 5i, the voltage applied to the electronic component 47 can be reduced, and an excessive voltage should be applied to the electronic component even when the voltage value of the power supply 41 is high. Instead, the power source 41 and the electronic component 47 can be connected.

Further, in the connector 1 of this embodiment, if the conductive terminal 45 connected to the power source 41 is inserted into the open holes 9a to 9i and used, various patterns can be connected, and the nine open holes 9a to 9i. Various resistance values can be obtained corresponding to each combination of inserting the conductive terminals 45 and 51 into 9i.

Therefore, when using the connector 1,
In consideration of the voltage value of the power source 41 connected to the electronic component 47 and the proper operating voltage of the electronic component 47, the open holes 9a to 9i are selected so that the most appropriate resistance value is obtained, and the conductive terminal 4 is selected.
5, 51 can be inserted and used.

In other words, the open holes 9a to 9j into which the conductive terminals 45 and 51 are inserted are appropriately selected so that an appropriate resistance value can be obtained from the electric resistors 5a to 5i provided in the wall portion 3. In addition, one or a plurality of electric resistors can be selected and connected to the power supply 41 and the electronic component 47.

Therefore, even for power supplies having various voltage values, the resistance value connected in series with the electronic component 47 can be selected according to the voltage value, and the voltage applied to the electronic component 47 can be changed. It becomes possible to set a predetermined appropriate value. Further, it is possible to connect various electronic components 47 having different proper operating voltages to the power supply 41 having a constant voltage value.

The embodiment of the present invention has been described above.
It is needless to say that the present invention is not limited to such embodiments and can be implemented in various modes without departing from the scope of the present invention. For example, as shown by the chain double-dashed line in FIG. 2, the surge absorbing element 100 may be provided on the surface of the outer wall portion 3b. This surge absorber 100
While being grounded, is electrically connected to the electronic component by inserting a conductive terminal into the open holes 9a to 9j. Therefore, for example, when a surge of large energy occurs due to lightning or the like, the surge is absorbed by the surge absorbing element 10.
Since it is absorbed by 0, the surge does not enter the electronic component connected to the connector 1, and the electronic component can be prevented from being damaged.

When forming the inner wall portion 3a and the outer wall portion 3b, the outer wall portion 3b formed separately is fitted into the inner wall portion 3a and joined together instead of two-color molding. Good. Further, on the surface of the wall portion, in order to clearly indicate the wiring position of the conductive member and the resistance value of the electric resistor, a guide is formed along the conductive member, or the position of the electric resistor and the vicinity of the open hole are provided. You may write letters etc. The guides and characters may be provided with irregularities on the surface of the wall or may be colored.

Furthermore, the shape of the wall portion does not have to be a cylindrical shape, and may be, for example, a prismatic cylinder or a flat plate.
