Next, fig. 4 shows an internal structure of the socket 1 from which the housing 2 is removed. The wire connecting portion of the present embodiment includes a conductive member provided with a contact and a spring member that urges a core wire of the wire to the conductive member.
On the base 3, a plurality of relay conductive plates 18a, 18b, 18c are arranged, which electrically connect the 1 st to 12 th wire connection portions H1 to H12 constituting the 1 st wire terminal block 5, the 13 th wire connection portion H13 and the 14 th wire connection portion H14 constituting the 2 nd wire terminal block 6, the 14 th card terminal connection portion 16 constituting the relay terminal block 7, and the 1 st to 14 th wire connection portions H1 to H14 and the 14 th card terminal connection portion 16.
As shown in fig. 5, the 1 st wire connecting portion H1 is composed of a conductive member 21 fixed to the base 3 and a spring member 22 integrally mounted with the conductive member 21.
As shown in fig. 6, the conductive member 21 is formed by bending a flat metal plate into a substantially cylindrical shape, and includes a spring member surface contact portion 23, a relay board connection portion 24, a pair of spring member locking pieces 25, a 1 st extending portion 26, a 1 st fixed contact 27 as a 1 st contact, a 2 nd extending portion 28, a 2 nd fixed contact 29 as a 2 nd contact, and a spring support piece 30.
That is, the relay board connecting portion 24 extends from a lower portion of the flat plate-shaped spring member surface contact portion 23, and the spring support piece 30 extends from an upper portion of the spring member surface contact portion 23.
The 1 st extending portion 26 is bent at a right angle from one side edge of the spring member surface contact portion 23, and the 2 nd extending portion 28 is bent at a right angle from the other side edge of the spring member surface contact portion 23 so as to be parallel to the 1 st extending portion 26, and extends longer than the 1 st extending portion 26.
A pair of spring member locking pieces 25 bent in a direction to approach each other are formed on the lower portions of the 1 st extending portion 26 and the 2 nd extending portion 28 on the spring member surface contact portion 23 side.

As shown in fig. 7, the spring member 22 is a member formed by bending a metal plate having conductivity, and includes: a flat conductive member surface contact portion 31; a conductor locking recess 32 formed at a lower portion of the conductor surface contact portion 31; a 1 st elastic part 33 and a 2 nd elastic part 34 extending from the upper part of the conductive surface contact part 31 in a band shape and bending in the same direction.
The 1 st elastic portion 33 includes: a protrusion 33a protruding toward the one surface 31a of the conductor surface contact portion 31; a bent portion 33b bent from the protruding portion 33a at an inner angle smaller than 90 °; and a 1 st movable contact piece 33c linearly extending from the bent portion 33 b.
The 2 nd elastic portion 34 includes: a linear extension 34a linearly extending from the upper portion of the conductor surface contact portion 31 on one surface; a bent portion 34b bent from the linear extension 34a at an inner angle of less than 90 °; and a 2 nd movable contact piece 34c linearly extending from the bent portion 34 b.
When the spring member 22 is integrally mounted on the conductor 21, the conductor surface contact portion 31 of the spring member 22 is inserted into the cylindrical space of the conductor 21, and the pair of spring member locking pieces 25 of the conductor 21 are elastically deformed and locked in the conductor locking recess of the spring member 22 in a state where the conductor surface contact portion 31 is surface-contacted with the spring member surface contact portion 23 of the conductor 21. In the spring member 22 integrally attached to the conductive member 21, the tip of the 1 st movable contact piece 33c of the 1 st elastic portion 33 abuts on the 1 st fixed contact 27 as the 1 st movable contact 33d, and the tip of the 2 nd movable contact piece 34c of the 2 nd elastic portion 34 abuts on the 2 nd fixed contact 29 as the 2 nd movable contact 34 d.
The other 2 nd to 14 th lead wire connection units H2 to 14 have the same structure as the 1 st lead wire connection unit H1.
Fig. 8 shows the opening positions of the 1 st to 4 th wire insertion holes L1 to L4 and the tool insertion hole 9 formed in the 1 st terminal surface 8A of the housing 2 for the 1 st to 4 th wire connection portions H1 to H4 arranged inside the socket 1 constituting the 1 st wire terminal block 5.
The signal wire insertion hole 10 of the 1 st wire insertion hole L1 opens in the vicinity of the 1 st movable contact 33d of the 1 st wire connecting portion H1, the distribution wire insertion hole 11 of the 1 st wire insertion hole L1 opens in the vicinity of the 2 nd movable contact 34d of the 1 st wire connecting portion H1, one of the 2 tool insertion holes 9 opens on the base end side of the 1 st movable contact 33c, and the other of the 2 tool insertion holes 9 opens on the base end side of the 2 nd movable contact 34 c.
Further, the opening positions of the 2 nd to 4 th wire insertion holes L2 to L4 and the tool insertion hole 9 with respect to the 2 nd to 4 th wire connecting parts H1 are also formed in the same configuration as the opening positions of the 1 st wire insertion hole L1 and the tool insertion hole 9 with respect to the above-described 1 st wire connecting part H1.
Although not shown, the opening positions of the 5 th to 12 th wire insertion holes L5 to L12 and the tool insertion hole 9 formed in the 2 nd terminal surface 8B and the 3 rd terminal surface 8C of the housing 2 with respect to the 5 th to 12 th wire connection portions H5 to H12 constituting the 1 st wire terminal block 5 are also the same as the opening positions of the 1 st to 4 th wire insertion holes L1 to L4 and the tool insertion hole 9 with respect to the 1 st to 4 th wire connection portions H1 to H4 shown in fig. 8.
In the 1 st lead terminal block 5 configured as described above, the signal lines are connected to the 1 st to 12 th lead connecting portions H1 to H12 as follows: a tool is inserted from the tool insertion hole 9 of the housing 2 opened on the base end side of the 1 st movable contact 33c to elastically deform the 1 st elastic portion 33 to bring the 1 st movable contact 33d of the 1 st movable contact 33c into a non-contact state with respect to the 1 st fixed contact 27, and after the signal wire is inserted from the signal wire insertion hole 10, the elastic deformation of the 1 st elastic portion 33 is released, and the 1 st movable contact 33d of the 1 st movable contact 33c and the 1 st fixed contact 27, which have been elastically restored, are connected to each other with the core wire of the signal wire sandwiched therebetween.
When the distribution wire is connected to the 1 st to 12 th wire connection portions H1 to H12, a tool is inserted from the tool insertion hole 9 of the housing 2 that opens at the base end side of the 2 nd movable contact piece 34c to elastically deform the 2 nd elastic portion 34 to bring the 2 nd movable contact 34d into a non-contact state with respect to the 2 nd fixed contact 29, and after the distribution wire is inserted from the distribution wire insertion hole 11, the elastic deformation of the 2 nd elastic portion 34 is released, and the core wire of the distribution wire is sandwiched between the 2 nd movable contact 34d and the 2 nd fixed contact 29 of the 2 nd movable contact piece 34c that have been elastically restored to be connected.
The lead terminal block of the present invention corresponds to the 1 st lead terminal block 5, the electrical equipment terminal block of the present invention corresponds to the relay terminal block 7, and the 2 reference lines of the present invention correspond to the 1 st reference line K1 and the 2 nd reference line K2.
Fig. 9 (a) is a schematic view showing the 1 st terminal surface 8A when the 1 st to 4 th lead connecting portions H1 to H4 of the 1 st lead terminal block 5 are connected to the signal line 35 and the distribution line 36.
Since the signal line insertion holes 10 at 4 are formed at equal intervals on the 1 st reference line K1, the distribution line insertion holes 11 at 4 are formed at equal intervals on the 2 nd reference line K1, and the 8 signal line insertion holes 10 and the distribution line insertion holes 11 are arranged in a staggered manner, the distance between the adjacent signal line insertion holes 10 and distribution line insertion holes 11 can be set to D1.
On the other hand, fig. 9 (b) shows a conventional configuration in which a plurality of signal line insertion holes S1 and distribution line insertion holes S2 are formed as a linear conductor terminal block on the reference line K3, but the distance D2 between adjacent signal line insertion holes S1 and distribution line insertion holes S2 is smaller than the distance D1 between adjacent signal line insertion holes 10 and distribution line insertion holes 11 shown in fig. 9 (a).
Here, in many cases, a marker pipe indicating a reference numeral and a character for identifying the type of each line is attached to the distal end side of the signal line 35 and the distribution line 36, and as shown in fig. 9 (b), when the distance D1 is provided between the adjacent signal line insertion hole 10 and the adjacent distribution line insertion hole 11, the signal line 35 and the distribution line 36 to which the marker pipe is attached are connected in a dense state, and therefore, the reference numeral and the character of the marker pipe cannot be easily confirmed.
In contrast, in embodiment 1 shown in fig. 9 (a), since the plurality of signal line insertion holes 10 and distribution line insertion holes 11 are arranged in a staggered pattern and the distance (distance D1) between the adjacent signal line insertion holes 10 and distribution line insertion holes 11 can be sufficiently ensured, even if the marking tubes are attached to all of the signal lines 35 and distribution lines 36 connected to the 1 st wire terminal block 5, the signal lines 35 and distribution lines 36 are not connected in a dense state, and the reference numerals and characters of the marking tubes can be easily confirmed.
The same effects can be obtained not only when the signal line 35 and the distribution line 36 are connected to the 1 st to 4 th wire connection units H1 to H4 but also when the signal line 35 and the distribution line 36 are connected to the 5 th to 12 th wire connection units H5 to H12 constituting the 1 st wire terminal block 5.
When the signal line 35 and the distribution line 36 are connected to or pulled out of the conductor connecting portions H1 to H12, the spring member 22 is elastically deformed by a tool inserted through the tool insertion hole 9 provided in the vicinity of the signal line insertion hole 10 and the distribution line insertion hole 11, and the pressing force of the spring member 22 is temporarily released, so that the 1 st and 2 nd movable contacts 33d and 34d can be separated from the 1 st and 2 nd fixed contacts 27 and 29.
When the signal line 35 and the distribution line 36 are connected to the conductor wire connection portions H1 to H12, the signal line 35 and the distribution line 36 are inserted from the signal line insertion hole 10 and the distribution line insertion hole 11, and then the spring member 22 is elastically restored, so that the core wire of the signal line 35 is sandwiched by the 1 st movable contact 33d and the 1 st fixed contact 27, and the core wire of the distribution line is sandwiched by the 2 nd movable contact 34d and the 2 nd fixed contact 29, and connection can be performed. As described above, the connection operation of the signal line 35 and the distribution line 36 can be easily performed.
Further, since the wire connection portions H1 to H12 are provided with the 1 st fixed contact 27 and the 1 st movable contact 33d connected to the signal line 35 and the 2 nd fixed contact 29 and the 2 nd movable contact 34d connected to the distribution line 36 by integrally mounting the spring member 22 to the conductive member 21, the number of components is reduced, and the device cost can be reduced.
Industrial applicability of the invention
As described above, according to the wire terminal block and the electrical equipment connection socket provided with the same of the present invention, even when a plurality of wires are connected, the indication of the marker pipe attached to the distal end side of each wire can be easily confirmed.
