Detailed Description
The terminal block and the control device according to the embodiment of the present invention will be described in detail below with reference to the drawings. Furthermore, the present invention is not limited by these embodiments.
Embodiment 1.
Fig. 1 is an oblique view showing an example of a terminal block according to embodiment 1 of the present invention. As shown in fig. 1, the terminal block 100 includes a housing 1, a conductive member 2, and a wire supporting member 3. Fig. 1 shows a housing 1 in perspective in order to explain the structure of a terminal block 100.
The housing 1 is formed in a box shape having a 1 st terminal surface 12 and a 2 nd terminal surface 14, the 1 st terminal surface 12 is formed with a wire insertion port 11 into which a wire 6 described later is inserted, and the 2 nd terminal surface 14 is formed with a conductive pin insertion port 13 into which a conductive pin 4 described later is inserted. The wire insertion port 11 is formed as an opening for communicating the inside and the outside of the housing 1 on the 1 st terminal surface 12, and the conductive pin insertion port 13 is formed as an opening for communicating the inside and the outside of the housing 1 on the 2 nd terminal surface 14. The wire insertion port 11 in embodiment 1 corresponds to an example of the 1 st wire insertion port.
The 1 st terminal surface 12 and the 2 nd terminal surface 14 of the housing 1 face each other, a direction from the 1 st terminal surface 12 side toward the 2 nd terminal surface 14 side is denoted as a Y-axis direction in fig. 1, a direction orthogonal to the Y-axis direction is denoted as an X-axis direction, and a direction orthogonal to both the Y-axis direction and the X-axis direction is denoted as a Z-axis direction. In the drawings, the X-axis direction, the Y-axis direction, and the Z-axis direction are all indicated by the same direction as in fig. 1. The Y-axis direction corresponds to an example of the 1 st direction, and the X-axis direction corresponds to an example of the 2 nd direction. The Y-axis direction may be referred to as the 1 st direction, the X-axis direction may be referred to as the 2 nd direction, and the Z-axis direction may be referred to as the 3 rd direction.
When the housing 1 is viewed in the Y-axis direction, the outer shape of the 2 nd terminal surface 14 is smaller than the outer shape of the 1 st terminal surface 12, and the 2 nd terminal surface 14 side can be inserted into an opening 52 of a substrate side terminal portion 5 described later. Thus, the terminal block 100 is configured to be capable of being inserted into and removed from the substrate-side terminal portion 5. The housing 1 has a fixing portion 15 protruding in the X-axis direction and extending in the Y-axis direction on the outer peripheral portion on the 1 st terminal surface 12 side. The fixing portion 15 has a communication hole, not shown, in the center, which communicates in the Y-axis direction, and is used to fix the terminal block 100 and the substrate-side terminal portion 5 by using a screw or the like when the terminal block 100 is inserted into the substrate-side terminal portion 5.
The conductive member 2 is constituted by leg portions 21a and 21b, a connecting portion 22, and a folded portion 23. The leg portions 21a and 21b are configured to extend in the Y-axis direction and face each other. The connection portion 22 is configured to connect one end of each of the leg portions 21a, 21b on the 1 st terminal surface side to each other. The connection portion 22 may be configured to connect one end of each of the leg portions 21a and 21b on the 1 st terminal surface side, and the connection portion 22 may have a linear shape or a curved shape. The folded portion 23 is formed by folding one end of each of the leg portions 21a, 21b on the 2 nd terminal surface side toward the side facing each other between the leg portions 21a, 21 b. That is, one end of the one leg portion 21a on the 2 nd terminal surface side is folded back toward the other leg portion 21b side to form the folded-back portion 23, and one end of the other leg portion 21b on the 2 nd terminal surface side is folded back toward the one leg portion 21a side to form the folded-back portion 23. The leg 21a in embodiment 1 corresponds to an example of the 1 st leg, and the leg 21b corresponds to an example of the 2 nd leg.
The conductive member 2 described above can be formed by bending a conductive metal plate. The material constituting the conductive member 2 is not particularly limited as long as it has conductivity, and is preferably a metal having relatively high conductivity, such as copper.
The conductive member 2 is arranged such that the connection portion 22 is on the 1 st terminal surface side in the housing 1, and such that when the conductive pin 4 is inserted from the conductive pin insertion port 13 formed in the 2 nd terminal surface 14 of the housing 1, the conductive pin 4 is inserted into a space between the leg portions 21a and 21b facing each other, and the conductive pin 4 is sandwiched between the leg portions 21a and 21 b. In addition, although embodiment 1 shows an example in which the folded portion 23 formed by folding one end of the leg portions 21a, 21b on the 2 nd terminal surface side is in contact with the conductive pin 4, in the case described above, it may be said that "the conductive pin 4 is sandwiched between the leg portions 21a, 21 b" in the present specification.
The wire supporting member 3 is constituted by a supporting portion 31 and an extending portion 32. The support portion 31 extends in the Y-axis direction and faces the leg portion 21a of the conductive member 2. The extension portion 32 extends from one end of the support portion 31 on the 1 st terminal surface 12 side toward the conductive member 2 side. The wire supporting member 3 in embodiment 1 corresponds to an example of the 1 st wire supporting member. The support portion 31 in embodiment 1 corresponds to an example of the 1 st support portion, and the extension portion 32 corresponds to an example of the 1 st extension portion.
The wire supporting member 3 as described above can be formed by bending a metal plate having conductivity. The wire supporting member 3 may be formed by subjecting a resin material to a known molding process. The wire supporting member 3 is preferably formed to have a spring characteristic such as a leaf spring that tries to return to its original shape even if deformed by an external force. The material constituting the wire supporting member 3 is not particularly limited as long as it can be processed to have a spring characteristic, and for example, a metal such as a copper alloy can be used.
In embodiment 1, an example is shown in which the support portion 31 and the leg portion 21a are arranged so as to face each other in the X-axis direction. The wire supporting member 3 is arranged to clamp the wire 6 between the conductive member 2 and the wire supporting member 3 when the wire 6 is inserted from the wire insertion port 11 formed in the 1 st terminal surface 12 of the housing 1.
Here, the positional relationship among the wire insertion port 11, the conductive member 2, and the wire supporting member 3 is formed on the 1 st terminal surface 12 such that the wire insertion port 11 is located between the conductive member 2 and the wire supporting member 3 when viewed in the Y-axis direction. However, when the wire 6 is inserted from the wire insertion port 11, the positional relationship among the wire insertion port 11, the conductive member 2, and the wire support member 3 may be such that the wire 6 is held between the conductive member 2 and the wire support member 3, and the wire insertion port 11 may be offset toward the wire support member 3 when viewed in the Y-axis direction, for example.
Fig. 2 is an oblique view showing an example of the substrate-side terminal portion according to embodiment 1 of the present invention. As shown in fig. 2, the substrate-side terminal portion 5 includes a substrate-side housing 51 and a conductive pin 4. Fig. 2 shows a perspective view of the substrate-side housing 51 in order to explain the structure of the substrate-side terminal 5.
The substrate-side housing 51 has a box shape having a terminal block insertion surface 53 and a pin fixing surface 54, the terminal block insertion surface 53 is formed with an opening 52 into which the 2 nd terminal surface 14 side of the terminal block 100 is inserted, and the pin fixing surface 54 is formed with a pin fixing hole 57 for fixing the conductive pin 4.
The substrate side frame 51 has a substrate side fixing portion 55 protruding in the X-axis direction and extending in the Y-axis direction on the outer peripheral portion of the substrate side frame 51 when viewed in the Y-axis direction. The substrate-side fixing portion 55 has a communication hole in the center, not shown, that communicates in the Y-axis direction. When the terminal block 100 is inserted into the substrate-side terminal portion 5, the substrate-side fixing portion 55 is provided at a position where the communication hole of the fixing portion 15 and the communication hole of the substrate-side fixing portion 55 of the housing 1 of the terminal block 100 communicate with each other. Thus, when the terminal block 100 is inserted into the substrate-side terminal portion 5, the terminal block 100 and the substrate-side terminal portion 5 can be fixed by screwing a screw or the like into the communication hole from the fixing portion 15 side toward the substrate-side fixing portion 55 side.
The conductive pin 4 is a rod-shaped conductive member, and is inserted and fixed into a pin fixing hole 57 formed in the pin fixing surface 54 of the substrate-side housing 51. The shape of the conductive pin 4 is not particularly limited, and a round bar shape, a square bar shape, or the like can be adopted. The material constituting the conductive pin 4 is not particularly limited as long as it has conductivity, and for example, copper, brass, or the like can be used.
Fig. 3 is a cross-sectional view showing an example of a connection state of a terminal block according to embodiment 1 of the present invention. Fig. 3 is a sectional view at the position III-III in fig. 1, showing a connection state in which the terminal block 100 and the substrate-side terminal portion 5 are connected, and the lead wire 6 is connected to the terminal block 100.
The terminal block 100 is connected to the substrate-side terminal portion 5 by inserting the 2 nd terminal surface 14 side of the housing 1 into the opening 52 of the substrate-side housing 51 of the substrate-side terminal portion 5. When the terminal block 100 is connected to the board-side terminal portion 5, the conductive pin 4 fixed to the board-side housing 51 is inserted from the conductive pin insertion port 13 formed in the 2 nd terminal surface 14 of the housing 1, and the conductive pin 4 is connected so as to be sandwiched between the leg portion 21a and the leg portion 21b of the conductive member 2. More specifically, the leg portions 21a and 21b sandwich the conductive pin 4 so that the folded portion 23 formed by folding one end of the leg portions 21a and 21b on the 2 nd terminal surface 14 side abuts against the conductive pin 4 to form an electrical contact. Thereby, the conductive pins 4 on the substrate side and the conductive members 2 of the terminal block 100 are electrically connected.
The terminal block 100 is connected to the lead wire 6 by inserting the lead wire 6 through the lead wire insertion port 11 formed in the 1 st terminal surface 12 of the housing 1. When the terminal block 100 is connected to the lead wire 6, the lead wire 6 is connected to be sandwiched between the conductive member 2 and the lead wire supporting member 3. More specifically, the lead wire supporting member 3 and the conductive member 2 hold the lead wire 6 so that the lead wire 6 is pressed against one leg portion 21a of the conductive member 2 at the tip of the extension portion 32 extending from the 1 st terminal surface 12 side end of the supporting portion 31 of the lead wire supporting member 3 toward the conductive member 2 side, and the leg portion 21a becomes an electrical contact. Thereby, the lead wire 6 and the conductive member 2 of the terminal block 100 are electrically connected. The wire 6 inserted into the wire insertion port 11 in embodiment 1 corresponds to an example of the 1 st wire.
The conductor 6 may be a conventionally known conductor in which a conductive core wire and an outer surface of the core wire are covered with an insulating ethylene coating. The tip of the conductive member 2 of the wire 6 held between the wire support member 3 may be in a state where the core wire is exposed, or may be in a state where the core wire is covered with a terminal such as a ferrule terminal.
Fig. 4 is a partial cross-sectional view showing an example of a control device having a terminal block according to embodiment 1 of the present invention. Fig. 4 is a sectional view at the position IV-IV in fig. 1, showing a partial sectional view showing a connection state in which the substrate-side terminal portion 5 is connected to the apparatus main body 203, and the terminal block 100 to which the lead wire 6 is connected to the substrate-side terminal portion 5.
The control device 200 is an electric device for controlling equipment constituting a production line, and includes a device main body 203 having a substrate 202, a substrate-side terminal portion 5, and a terminal block 100 in a device housing 201. The control device 200 controls the equipment by connecting the wire 6 to the terminal block 100, and transmitting the control signal sent from the control device 200 to the equipment via the wire 6.
The device housing 201 is a box-shaped outer housing that houses the substrate 202, and is configured to be connectable to the substrate-side terminal portion 5. Specifically, a recess 201b for fitting the substrate-side housing 51 of the substrate-side terminal portion 5 is formed in the front surface 201a of the device housing 201, and an insertion through-hole 201c through which the conductive pin 4 fixed to the substrate-side terminal portion 5 can be inserted is formed in the bottom surface of the recess 201 b.
The substrate 202 is a circuit substrate on which the substrate wiring 204 is printed, and a semiconductor chip or the like to which a control signal or the like is sent when the control device 200 controls the apparatus is mounted. The substrate 202 transmits the transmitted control signal or the like as an electrical signal through the substrate wiring 204.
The substrate-side terminal portion 5 is fitted into the recess 201b of the device housing 201, and is connected to the device housing 201 so that one end of the conductive pin 4 is electrically connected to the substrate wiring 204 of the substrate 202. The conductive pins 4 and the substrate wiring 204 of the substrate 202 may be electrically connected by, for example, soldering.
As described above, the terminal block 100 is connected to the substrate-side terminal portion 5 so that the 2 nd terminal surface 14 side of the housing 1 is inserted into the opening 52 of the substrate-side housing 51 of the substrate-side terminal portion 5, and the conductive pin 4 is sandwiched between the leg portion 21a and the leg portion 21b of the conductive member 2. As described above, the terminal block 100 is connected by sandwiching the wire 6 between the conductive member 2 and the wire supporting member 3. Thus, the substrate wiring 204 of the substrate 202, the conductive pins 4 of the substrate-side terminal portion 5, the conductive members 2 of the terminal block 100, and the wires 6 are electrically connected, and the control device 200 can send a control signal to the apparatus via the wires 6.
As described above, in the terminal block 100 according to embodiment 1 of the present invention, the conductive member 2 and the wire supporting member 3 are arranged so as to face each other in the 2 nd direction (i.e., the X-axis direction) perpendicular to the 1 st direction (i.e., the Y-axis direction) from the 1 st terminal surface 12 side toward the 2 nd terminal surface 14 side in the housing 1. The terminal block 100 is configured such that the lead wire 6 is sandwiched between the conductive member 2 and the lead wire supporting member 3 when the lead wire 6 is inserted, and the conductive pin 4 is sandwiched between the opposing leg portions 21a and 21b of the conductive member 2 when the conductive pin 4 is inserted. This can suppress an increase in the length of the terminal block 100 in the direction from the 1 st terminal surface 12 side toward the 2 nd terminal surface 14 side (i.e., in the Y-axis direction).
The terminal block 100 according to embodiment 1 of the present invention has a folded portion 23 formed by folding back one end of the conductive member 2 on the 2 nd terminal surface 14 side of the leg portions 21a and 21b facing each other. Thus, when the terminal block 100 clamps the conductive pin 4 by the leg portions 21a and 21b facing each other, the folded-back portion 23 becomes an electrical contact with the conductive pin 4, and the reliability of the electrical connection between the conductive pin 4 and the conductive member 2 can be improved.
The terminal block 100 according to embodiment 1 of the present invention is configured to have an extension portion 32 extending from one end of the 1 st terminal surface side of the support portion 31 of the wire support member 3 toward the conductive member 2 side. Thus, when the terminal block 100 clamps the wire 6 between the wire supporting member 3 and the conductive member 2, the one leg portion 21a of the wire 6 to the conductive member 2 is pressed at the tip end of the extension portion 32, and the leg portion 21a serves as an electrical contact, so that the reliability of the electrical connection between the wire 6 and the conductive member 2 can be improved.
Further, since the control device 200 having the terminal block 100 according to embodiment 1 of the present invention suppresses an increase in the length of the terminal block 100 in the direction from the 1 st terminal surface 12 side toward the 2 nd terminal surface 14 side, even if the terminal block 100 is connected to the device main body 203, the protruding length of the terminal block 100 protruding from the device main body 203 can be reduced, and an increase in size as a whole of the control device 200 can be suppressed.

The housing 1a is formed in a box shape having a 1 st terminal surface 12a and a 2 nd terminal surface 14, and the 1 st terminal surface 12a is formed with a wire insertion port 11a into which the other wire 6 is inserted, in addition to the wire insertion port 11 into which the wire 6 is inserted. That is, the 1 st terminal surface 12a has 2 wire insertion openings 11, 11a. The wire insertion port 11a is formed as an opening communicating the inside and the outside of the housing 1a on the 1 st terminal surface 12a, similarly to the wire insertion port 11. The 1 st terminal surface 12a and the 2 nd terminal surface 14 of the housing 1a face each other. In the embodiment shown in fig. 5 of embodiment 2, the wire insertion port 11 corresponds to an example of the 1 st wire insertion port, and the wire insertion port 11a corresponds to an example of the 2 nd wire insertion port.

The wire supporting member 3a is constituted by a supporting portion 31a and an extending portion 32 a. The support portion 31a extends in the Y-axis direction and faces the leg portion 21b of the conductive member 2. The extension portion 32a extends from one end of the support portion 31a on the 1 st terminal surface 12a side toward the conductive member 2 side. In the embodiment of embodiment 2 shown in fig. 5, the wire supporting member 3 corresponds to an example of the 1 st wire supporting member. The support portion 31 corresponds to an example of the 1 st support portion, and the extension portion 32 corresponds to an example of the 1 st extension portion. The wire supporting member 3a corresponds to an example of the 2 nd wire supporting member.

As shown in fig. 5, the 2 wire support members 3 and 3a are disposed in the housing 1a so as to face each other with the conductive member 2 interposed therebetween. Specifically, the 1 wire supporting member 3 is disposed in the housing 1a so that the supporting portion 31 faces the leg portion 21a of the conductive member 2. The other 1 wire supporting member 3a is disposed in the housing 1a so that the supporting portion 31a faces the leg portion 21b of the conductive member 2. The 2 wire supporting members 3 and 3a are arranged to clamp the wire 6 inserted from the 1 wire insertion port 11 between the 1 wire supporting member 3 and the conductive member 2, and to clamp the wire 6 inserted from the other 1 wire insertion port 11a between the other 1 wire supporting member 3a and the conductive member 2. In the embodiment of embodiment 2 shown in fig. 5, the wire 6 inserted into the wire insertion port 11 corresponds to an example of the 1 st wire. The wire 6 inserted into the wire insertion port 11a corresponds to an example of the 2 nd wire.
Here, the positional relationship among the wire insertion port 11a, the conductive member 2, and the wire support member 3a is configured to be the same as the positional relationship among the wire insertion port 11, the conductive member 2, and the wire support member 3 in embodiment 1 described above.
Thereby, the wire 6 inserted from the 1 wire insertion port 11 is sandwiched between the 1 wire support member 3 and the conductive member 2, and the wire 6 inserted from the other 1 wire insertion port 11a is sandwiched between the other 1 wire support member 3a and the conductive member 2.
The terminal block 100b according to embodiment 2 shown in fig. 6 includes a housing 1b, a conductive member 2, and 4 wire supporting members 3, 3a, 3b, and 3c. Note that the same components as those of embodiment 2 described with reference to fig. 5 are denoted by the same reference numerals, and detailed description thereof is omitted. Fig. 6 shows a housing 1b in perspective in order to explain the structure of the terminal block 100 b.

That is, the 1 st terminal surface 12b has 4 wire insertion openings 11, 11a, 11b, 11c. The lead insertion openings 11b and 11c are formed as openings for communicating the inside and the outside of the housing 1b on the 1 st terminal surface 12b, similarly to the lead insertion openings 11 and 11 a. The 1 st terminal surface 12b and the 2 nd terminal surface 14 of the housing 1b face each other. In the embodiment shown in fig. 6 of embodiment 2, the wire insertion port 11 corresponds to an example of the 1 st wire insertion port, and the wire insertion ports 11a, 11b, and 11c correspond to an example of the 2 nd wire insertion port.
The terminal block 100b has 4 wire supporting members 3, 3a, 3b, 3c. The wire supporting member 3 is composed of a supporting portion 31 and an extending portion 32, similarly to the wire supporting member 3 shown in fig. 5. The wire supporting member 3a is composed of a supporting portion 31a and an extending portion 32a, similarly to the wire supporting member 3a shown in fig. 5. The wire supporting members 3b and 3c have the same structure as the wire supporting members 3 and 3a shown in fig. 5. That is, the wire supporting members 3b and 3c are constituted by supporting portions 31b and 31c having the same structure as the supporting portions 31 and 31a and extending portions 32b and 32c having the same structure as the extending portions 32 and 32 a. In the embodiment of embodiment 2 shown in fig. 6, the wire supporting member 3 corresponds to an example of the 1 st wire supporting member. The support portion 31 corresponds to an example of the 1 st support portion, and the extension portion 32 corresponds to an example of the 1 st extension portion. The wire supporting members 3a, 3b, and 3c correspond to one example of the 2 nd wire supporting member. The support portions 31a, 31b, and 31c correspond to an example of the 2 nd support portion, and the extension portions 32a, 32b, and 32c correspond to an example of the 2 nd extension portion.
As shown in fig. 6, 2 wire supporting members 3, 3a among the 4 wire supporting members 3, 3a, 3b, 3c are disposed in the housing 1b so as to face each other through the conductive member 2. As shown in fig. 6, the remaining 2 lead support members 3b and 3c are disposed in the housing 1b so as to face each other with the conductive member 2 interposed therebetween. On the basis of this, the wire supporting member 3b is disposed adjacent to the wire supporting member 3 in the Z-axis direction, and the wire supporting member 3c is disposed adjacent to the wire supporting member 3a in the Z-axis direction.
As shown in fig. 6, the 1 wire supporting members 3 are disposed in the housing 1b so that the supporting portions 31 face the leg portions 21a of the conductive members 2. The other 1 wire supporting member 3a is disposed in the housing 1b so that the supporting portion 31a faces the leg portion 21b of the conductive member 2. The other 1 wire supporting member 3b is disposed in the housing 1b so that the supporting portion 31b faces the leg portion 21a of the conductive member 2. The last 1 other wire supporting member 3c is disposed in the housing 1b so that the supporting portion 31c faces the leg portion 21b of the conductive member 2.
In embodiment 2 shown in fig. 6, the structure of the conductive member 2 is the same as that of embodiment 1, but the length in the Z-axis direction is longer than that of embodiment 1. Accordingly, the respective wire supporting members 3, 3b adjacent in the Z-axis direction can be arranged so as to oppose the different positions in the Z-axis direction of the leg portion 21a of the conductive member 2, and the respective wire supporting members 3a, 3c adjacent in the Z-axis direction can be arranged so as to oppose the different positions in the Z-axis direction of the leg portion 21b of the conductive member 2.
Further, 2 wire supporting members 3, 3a among the 4 wire supporting members 3, 3a, 3b, 3c are arranged to clamp the wire 6 inserted from the 1 wire insertion port 11 between the 1 wire supporting member 3 and the conductive member 2, and to clamp the wire 6 inserted from the other 1 wire insertion port 11a between the other 1 wire supporting member 3a and the conductive member 2. The remaining 2 wire supporting members 3b, 3c among the 4 wire supporting members 3, 3a, 3b, 3c are configured to clamp the wire 6 inserted from the 1 wire insertion port 11b between the 1 wire supporting member 3b and the conductive member 2, and configured to clamp the wire 6 inserted from the other 1 wire insertion port 11c between the other 1 wire supporting member 3c and the conductive member 2. In the embodiment of embodiment 2 shown in fig. 6, the wire 6 inserted into the wire insertion port 11 corresponds to an example of the 1 st wire. The wires 6 inserted into the wire insertion openings 11a, 11b, and 11c correspond to one example of the 2 nd wire.
Here, the positional relationship between the wire insertion port 11a, the conductive member 2, and the wire support member 3a, the positional relationship between the wire insertion port 11b, the conductive member 2, and the wire support member 3b, and the positional relationship between the wire insertion port 11c, the conductive member 2, and the wire support member 3c are the same as those of the wire insertion port 11, the conductive member 2, and the wire support member 3 in embodiment 1.
Thereby, the wire 6 inserted from the 1 wire insertion port 11 is sandwiched between the 1 wire support member 3 and the conductive member 2, and the wire 6 inserted from the other 1 wire insertion port 11a is sandwiched between the other 1 wire support member 3a and the conductive member 2. The wire 6 inserted from the 1 wire insertion port 11b is sandwiched between the 1 wire support member 3b and the conductive member 2, and the wire 6 inserted from the other 1 wire insertion port 11c is sandwiched between the other 1 wire support member 3c and the conductive member 2.
The terminal blocks 100a and 100b according to embodiment 2 shown in fig. 5 and 6 can be connected to the substrate-side terminal portion 5 in the same manner as the terminal block 100 shown in embodiment 1. When the terminal blocks 100a and 100b are connected to the substrate-side terminal section 5, the conductive pins 4 of the substrate-side terminal section 5 are sandwiched between the leg portions 21a and 21b of the conductive members 2 of the terminal blocks 100a and 100b and connected.
The terminal blocks 100a and 100b are connected to the apparatus main body 203 in the same manner as in embodiment 1, and can be configured as a control apparatus 200 having the terminal block 100a and a control apparatus 200 having the terminal block 100 b.
As described above, the terminal blocks 100a and 100b according to embodiment 2 of the present invention can suppress the increase in the length of the terminal blocks 100a and 100b in the direction from the 1 st terminal surface 12a and 12b side toward the 2 nd terminal surface 14 side (i.e., the Y-axis direction) as in the terminal block 100 according to embodiment 1.
The control device 200 having the terminal blocks 100a and 100b according to embodiment 2 of the present invention can suppress an increase in size of the entire control device 200, as in the control device 200 according to embodiment 1.
The terminal blocks 100a and 100b according to embodiment 2 of the present invention are configured such that a plurality of wire insertion openings 11, 11a, 11b, and 11c are formed in the 1 st terminal surfaces 12a and 12b, and the wires 6 inserted from the wire insertion openings 11, 11a, 11b, and 11c can be held between the wire support members 3, 3a, 3b, and 3c and the 1 conductive member 2. Thus, the terminal blocks 100a and 100b can electrically connect the plurality of wires 6 together for 1 conductive pin 4. This makes it possible to suppress an increase in the number of structural members of the terminal block and to suppress an increase in the size of the terminal block, compared with a case where a plurality of terminal blocks capable of connecting 1 wire 6 are used and a plurality of wires 6 are connected.
The control device 200 having the terminal blocks 100a and 100b according to embodiment 2 of the present invention is configured to connect 1 conductive pin 4 to the substrate wiring 204 of the substrate 202 so that a control signal can be sent from the 1 conductive pin 4 to the plurality of wires 6. As a result, the number of conductive pins 4 connected to the substrate 202 can be reduced, and the occupied area of the substrate wiring 204 for connecting the conductive pins 4 to the substrate 202 can be reduced, as compared with the case where a plurality of conductive wires 6 are connected using a plurality of terminal blocks capable of connecting 1 conductive wire.
Embodiment 3.
Fig. 7 is an oblique view showing an example of a terminal block according to embodiment 3 of the present invention. The same reference numerals are used to describe the same components as those of embodiment 1, and a specific description thereof is omitted.

The housing 1c is formed in a box shape having a 1 st terminal surface 12 and a 2 nd terminal surface 14 c. The 1 st terminal surface 12 is formed with a wire insertion port 11 in the same manner as in embodiment 1. The 2 nd terminal surface 14c is formed with a conductive pin insertion port 13 into which the conductive pin 4 is inserted, and has an engaging portion 16 protruding from the 2 nd terminal surface 14c toward the Y-axis direction. The housing 1c does not have the fixing portion 15. The wire insertion port 11 in embodiment 3 corresponds to an example of the 1 st wire insertion port.
The engagement portion 16 protruding from the 2 nd terminal surface 14c is configured to engage with a substrate-side terminal portion 5c described later. Specifically, the terminal surface 14c is formed in an L-shape protruding in the Y-axis direction from the 2 nd terminal surface, and the tip thereof extends in the Z-axis direction.
The terminal block 100c is provided with a conductive member 2 and a wire supporting member 3 in a housing 1c, as in embodiment 1. The conduction member 2 is constituted by the leg portions 21a and 21b, the connecting portion 22, and the folded portion 23, and has the same structure as that of embodiment 1, and therefore, a description thereof will be omitted. The wire supporting member 3 is composed of the supporting portion 31 and the extending portion 32, and has the same structure as embodiment 1, and therefore, a description thereof will be omitted. The positional relationship between the conductive member 2 and the wire supporting member 3 is the same as that of embodiment 1 and is disposed in the housing 1c, and therefore, the description thereof will be omitted. The leg portion 21a in embodiment 3 corresponds to an example of the 1 st leg portion, and the leg portion 21b corresponds to an example of the 2 nd leg portion. The wire support member 3 in embodiment 3 corresponds to an example of the 1 st wire support member. In embodiment 3, the support portion 31 corresponds to an example of the 1 st support portion, and the extension portion 32 corresponds to an example of the 1 st extension portion.
Fig. 8 is an oblique view showing an example of the substrate-side terminal portion according to embodiment 3 of the present invention. As shown in fig. 8, the board-side terminal portion 5c includes a board-side housing 51c and the conductive pin 4. Fig. 8 shows a perspective view of the substrate-side housing 51c in order to explain the structure of the substrate-side terminal 5 c.
The substrate-side housing 51c has a box shape having a terminal block insertion surface 53 and a pin fixing surface 54c, the terminal block insertion surface 53 is formed with an opening 52 into which the 2 nd terminal surface 14c side of the terminal block 100c is inserted, and the pin fixing surface 54c is formed with a pin fixing hole 57 for fixing the conductive pin 4 and a receiving portion 56 for engaging the engaging portion 16. The substrate-side housing 51c does not have the substrate-side fixing portion 55.
The housing portion 56 is a space formed by opening the pin fixing surface 54c, and is formed by an opening area into which the engaging portion 16 can be inserted. The housing portion 56 is formed as a space bent in the Z-axis direction so that the tip of the engaging portion 16 extending in the Z-axis direction can be engaged.
Fig. 9 is a cross-sectional view showing an example of an engagement portion of a terminal block according to embodiment 3 of the present invention. Fig. 9 is a cross-sectional view of the position IX-IX in fig. 7, showing a state in which the engaging portion 16 of the terminal block 100c is engaged with the housing portion 56 of the substrate-side terminal portion.
The terminal block 100c is inserted into the opening 52 of the substrate-side housing 51c of the substrate-side terminal 5c through the 2 nd terminal surface 14c side of the housing 1c, and is connected to the substrate-side terminal 5 c. When the terminal block 100c is connected to the substrate-side terminal portion 5c, the conductive pins 4 fixed to the substrate-side housing 51c are connected to each other so as to be sandwiched between the leg portions 21a and 21b of the conductive member 2, as in embodiment 1. When the terminal block 100c is connected to the substrate-side terminal portion 5c, the engaging portion 16 formed on the 2 nd terminal surface 14c of the housing 1c is inserted into the receiving portion 56 formed on the substrate-side terminal portion 5 c.
Then, the terminal block 100c slides in the Z-axis direction in a state where the engaging portion 16 is inserted into the housing portion 56 of the substrate-side terminal portion 5c, whereby the engaging portion 16 engages with the housing portion 56 of the substrate-side terminal portion 5c, and the terminal block 100c and the substrate-side terminal portion 5c are fixed in a state of being connected. Here, the leg portions 21a and 21b of the conductive member 2 and the conductive pin 4 of the terminal block 100c function as guides for assisting sliding of the terminal block 100c when the engaging portion 16 is engaged with the housing portion 56 of the substrate-side terminal portion 5 c. This allows the engagement portion 16 to be engaged more accurately.
The terminal block 100c and the substrate-side terminal portion 5c are connected to the apparatus main body 203 in the same manner as in embodiment 1, and can be configured as a control apparatus 200 having the terminal block 100 c.
As described above, the terminal block 100c according to embodiment 3 of the present invention can suppress the increase in the length of the terminal block 100c in the direction from the 1 st terminal surface 12 side to the 2 nd terminal surface 14c side (i.e., the Y-axis direction) as in the terminal block 100 according to embodiment 1.
The control device 200 having the terminal block 100c according to embodiment 3 of the present invention can suppress an increase in size of the entire control device 200, as in the control device 200 according to embodiment 1.
Further, since the terminal block 100c according to embodiment 3 of the present invention is configured such that the engaging portion 16 is provided on the 2 nd terminal surface 14c of the housing 1c, a fixing portion for fixing the terminal block is not required, and an increase in the outer shape of the terminal block 100c as viewed in the Y-axis direction can be suppressed.
Embodiment 4.
Fig. 10 is an oblique view showing an example of a terminal block according to embodiment 4 of the present invention. The same reference numerals are used to describe the same components as those of embodiment 1, and a specific description thereof is omitted. Next, a structure different from that of embodiment 1 will be specifically described.
The terminal block 100d according to embodiment 4 shown in fig. 10 includes a housing 1d, a conductive member 2, and a wire supporting member 3. Fig. 10 shows a housing 1d in perspective in order to explain the structure of the terminal block 100 d.
The housing 1d is formed in a box shape having a 1 st terminal surface 12d and a 2 nd terminal surface 14. The 1 st terminal surface 12d is further formed with an inspection port 17 in addition to the wire insertion port 11. The wire insertion port 11 in embodiment 4 corresponds to an example of the 1 st wire insertion port.
The terminal block 100d is provided with a conductive member 2 and a wire supporting member 3 in a housing 1d as in embodiment 1. The conduction member 2 is constituted by the leg portions 21a and 21b, the connecting portion 22, and the folded portion 23, and has the same structure as that of embodiment 1, and therefore, a description thereof will be omitted. The wire supporting member 3 is composed of the supporting portion 31 and the extending portion 32, and has the same structure as embodiment 1, and therefore, a description thereof will be omitted. The positional relationship between the conductive member 2 and the wire supporting member 3 is the same as that of embodiment 1 and is disposed in the housing 1c, and therefore, the description thereof will be omitted. The leg 21a in embodiment 4 corresponds to an example of the 1 st leg, and the leg 21b corresponds to an example of the 2 nd leg. The wire supporting member 3 in embodiment 4 corresponds to an example of the 1 st wire supporting member. In embodiment 4, the support portion 31 corresponds to an example of the 1 st support portion, and the extension portion 32 corresponds to an example of the 1 st extension portion.
The inspection port 17 formed in the 1 st terminal surface 12d is formed at a position facing the connection portion 22 of the conductive member 2 disposed in the housing 1d of the terminal block 100 d. The inspection port 17 is formed as an opening that communicates the inside and the outside of the housing 1 d.
Fig. 11 is a cross-sectional view showing an example of an inspection port of a terminal block according to embodiment 4 of the present invention. Fig. 11 is a sectional view at the position XI-XI in fig. 10, showing a connection state where the terminal block 100d and the substrate-side terminal portion 5 are connected, and the lead wire 6 is connected to the terminal block 100. These connection states are the same as those of embodiment 1, and therefore, description thereof is omitted.
The terminal block 100d can confirm conduction between the conductive member 2 and at least one of the lead wire 6 and the conductive pin 4 by inserting the tip of the tester T from the inspection port 17 formed in the 1 st terminal surface 12d of the housing 1d and bringing the tip of the tester T into contact with the connection portion 22 of the conductive member 2. The tester T is a device capable of measuring a current or a voltage.
Since both the lead wire 6 and the substrate-side terminal portion 5 are connected to the terminal block 100d shown in fig. 11, the conduction between the lead wire 6 and the conductive member 2 and between the conductive pin 4 and the conductive member 2 can be confirmed by inserting the tester T from the inspection port 17 of the terminal block 100d and bringing the tip of the tester T into contact with the connection portion 22 of the conductive member 2. That is, if the tester T is inserted from the inspection port 17 in the state where the lead wire 6 is connected, and the tip of the tester T is brought into contact with the connection portion 22 of the conductive member 2, conduction between the lead wire 6 and the conductive member 2 can be confirmed, and if the tester T is inserted from the inspection port 17 in the state where the board-side terminal portion 5 is connected, conduction between the conductive pin 4 and the conductive member 2 can be confirmed by bringing the tip of the tester T into contact with the connection portion 22 of the conductive member 2.
The terminal block 100d and the substrate-side terminal portion 5 are connected to the apparatus main body 203 in the same manner as in embodiment 1, and can be configured as a control apparatus 200 having the terminal block 100 d.
As described above, the terminal block 100d according to embodiment 4 of the present invention can suppress the increase in the length of the terminal block 100d in the direction from the 1 st terminal surface 12d side toward the 2 nd terminal surface 14 side (i.e., the Y-axis direction) as in the terminal block 100 according to embodiment 1.
The control device 200 having the terminal block 100d according to embodiment 4 of the present invention can suppress an increase in size of the entire control device 200, as in the control device 200 according to embodiment 1.
In addition, in the terminal block 100d according to embodiment 4 of the present invention, the electrical contact of the lead wire 6 and the electrical contact of the conductive pin 4 are shared by the conductive member 2, and the inspection port 17 is formed in the housing 1d at a position facing the connection portion 22 of the conductive member 2 disposed in the housing 1d, whereby the conduction between at least one of the lead wire 6 and the conductive pin 4 and the conductive member 2 can be easily confirmed using the inspection port 17.
The control device 200 having the terminal block 100d according to embodiment 4 of the present invention can confirm conduction between the conductive member 2 and at least one of the lead wire 6 and the conductive pin 4 by inserting the tester T from the inspection port 17 formed in the terminal block 100 d. The control device 200 having the terminal block 100d can easily confirm conduction without detaching the terminal block 100d and the substrate-side terminal portion 5 from the device main body 203.
Modification examples.
The conductive member 2 described in embodiments 1 to 4 has been described as having the folded-back portion 23 formed by folding back the end portion on the 2 nd terminal surface side of the leg portions 21a, 21b, but the shape of the end portion on the 2 nd terminal surface side of the leg portions 21a, 21b of the conductive member 2 may be another shape if the conductive pin 4 can be sandwiched between the leg portions 21a, 21 b. For example, as shown in fig. 12, the leg portions 21a and 21b of the conductive member 2 may be configured not to have the folded-back portion 23. Even if the legs 21a, 21b of the conductive member 2 do not have the folded-back portion 23, the conductive pin 4 can be sandwiched between the leg 21a and the leg 21 b.
The wire supporting member 3 described in embodiments 1 to 4 above is described as being composed of the supporting portion 31 and the extending portion 32, but if the wire supporting member 3 has the supporting portion 31, the wire 6 can be sandwiched between the conductive member 2 and the wire supporting member 3, other configurations may be used. For example, as shown in fig. 13, the wire supporting member 3e may be constituted by a supporting portion 31e whose end portion on the 1 st terminal surface 12 side is curved. The wire supporting member 3e as described above can also clamp the wire 6 between the conductive member 2 and the wire supporting member 3 e.
In the terminal blocks 100, 100a, 100b, 100c, and 100d described in the above embodiments 1 to 4, the structure in which 1 conductive pin 4 is sandwiched between the leg 21a and the leg 21b of 1 conductive member 2 facing each other has been described, but a plurality of conductive pins 4 may be sandwiched between the leg 21a and the leg 21b of 1 conductive member 2 facing each other. In the case as described above, the reliability of the electrical connection between the conductive member 2 and the conductive pin 4 can be further improved.
The control device 200 described in embodiments 1 to 4 above is described in such a manner that the device housing 201 is formed with the recess 201b, and the insertion through-hole 201c through which the conductive pin 4 can be inserted is formed in the bottom surface of the recess 201 b. However, the device housing 201 of the control device 200 may be another type if it is a box-shaped external housing that houses the substrate 202 and is capable of connecting the substrate-side terminal portion 5. For example, the recess 201b of the device housing 201 may have a shape not having a bottom surface. In other words, the recess 201b of the device housing 201 may be configured such that the insertion through-hole 201c shown in fig. 4 is formed on the entire surface of the bottom surface of the recess 201b, and the insertion through-hole 201c is formed so as to be capable of being inserted through the substrate-side terminal portion 5 to which the conductive pin 4 is fixed.
The terminal blocks 100, 100a, 100b, and 100d described in embodiment 1, embodiment 2, and embodiment 4 are described as having the fixing portions 15 in the housings 1, 1a, 1b, and 1d, but may be configured to have the engaging portions 16 described in embodiment 3 instead of the fixing portions 15. When the terminal blocks 100, 100a, 100b, and 100d are configured to have the engaging portions 16, the substrate-side terminal portion 5 is also configured to be described as the substrate-side terminal portion 5c having the housing portion 56 described in embodiment 3, and thus the terminal blocks 100, 100a, 100b, and 100d can be connected to and fixed to the substrate-side terminal portion 5c by the engaging portions 16.
The terminal block 100 described in embodiment 1 is described in a structure in which the support portion 31 of the wire support member 3 and the leg portion 21a of the conductive member 2 are arranged so as to face each other in the housing 1. However, the terminal block 100 may be configured such that the support portion 31 of the wire support member 3 and the leg portion 21b of the conductive member 2 face each other. In the case described above, the leg portion 21b corresponds to an example of the 1 st leg portion.
The terminal blocks 100a and 100b described in embodiment 2 are described as being capable of electrically connecting 2 or 4 wires 6 together, but may be configured by connecting a plurality of wires together. For example, other configurations may be configured such that the wire insertion openings 11a and 11b and the wire supporting members 3 and 3b are provided instead of the wire insertion openings 11a and 11c and the wire supporting members 3a and 3c of the terminal block 100b shown in fig. 6, and 2 wires are collected and electrically connected. In addition, another configuration may be adopted in which the wire insertion openings 11c and the wire supporting members 3c of the terminal block 100b shown in fig. 6 are not provided, but the wire insertion openings 11, 11a, 11b and the wire supporting members 3, 3a, 3b are provided, and the 3 wires are collected and electrically connected.
In addition, another configuration is such that the wire insertion openings 11a and 11c and the wire supporting members 3a and 3c of the terminal block 100b shown in fig. 6 are not provided, but the wire insertion openings 11 and 11b and the wire supporting members 3 and 3b are provided, and a new wire insertion opening is formed so as to be adjacent to the wire insertion opening 11b in the Z-axis direction, and the new wire supporting members are arranged so as to be adjacent to the wire supporting member 3b in the Z-axis direction. Thus, the terminal block of the other structure can be configured such that 3 wires of the terminal block are gathered and electrically connected. In addition, another configuration is such that a new wire insertion port is formed so as to be adjacent to the wire insertion ports 11b and 11c in the Z-axis direction with respect to the terminal block 100b shown in fig. 6, and a new wire support member is arranged so as to be adjacent to the wire support members 3b and 3c in the Z-axis direction. Thus, the terminal block of other structure can be configured to collect and electrically connect 6 wires.
As described above, the terminal block according to the present invention can electrically connect a plurality of wires by continuously adding the wire insertion port and the wire support member in the Z-axis direction.
The engagement portion 16 of the terminal block 100c described in embodiment 3 is not limited to the L-shape described in embodiment 3, as long as it can be engaged with the substrate-side terminal portion 5 c. For example, the engaging portion 16 may be formed in a T shape protruding from the 2 nd terminal surface 14c in the Y-axis direction and having a distal end extending toward both sides in the Z-axis direction.
The inspection port 17 provided in the terminal block 100d described in embodiment 4 may have the plurality of wire insertion ports 11, 11a, 11b, 11c and the plurality of wire supporting members 3, 3a, 3b, 3c described in embodiment 2, and may be formed at positions facing the connection portion 22 of the conductive member 2 with respect to the 1 st terminal surfaces 12a, 12b of the terminal blocks 100a, 100b, in which the plurality of wires 6 can be collected and electrically connected. Thus, the terminal blocks 100a and 100b, which can electrically connect the plurality of wires 6 together, can easily confirm the conduction between each wire 6 inserted from the wire insertion port 11, 11a, 11b, and 11c and the conduction between the conductive member 2 and at least one of the conductive pin 4 and the conduction member 2 through the inspection port 17.
The substrate-side terminal portions 5 and 5c described in embodiments 1 to 4 are embedded in the device main body 203 of the control device 200, and the structure of the substrate-side terminal portions 5 and 5c connected to the device main body 203 is described. However, the substrate-side terminal portions 5 and 5c may be formed as a part of the device housing 201 of the device main body 203. For example, the device main body 203 can form the recess 201b of the device housing 201 by the same shape as the substrate side housings 51, 51c of the substrate side terminal portions 5, 5 c. In this way, the substrate-side terminal portions 5, 5c can be configured as a part of the apparatus main body 203, and the terminal blocks 100, 100a, 100b, 100c can be directly connected to the apparatus main body 203 of the control apparatus 200. With the above configuration, an increase in the number of components when the terminal block is connected to the control device can be prevented.
In embodiments 1 to 4, the structure of the terminal blocks 100, 100a, 100b, and 100c has been described as the terminal blocks, but the terminal blocks may be configured in a state where the terminal blocks 100, 100a, 100b, and 100c are connected to the substrate-side terminal portions 5 and 5 c.
The configuration shown in the above embodiment shows an example of the content of the present invention, and other known techniques may be combined, modified, or omitted as appropriate, and the scope of the technical idea shown in the embodiment is also included.
