As specific structures of wires, various wires such as ferrule terminals and stripped cables can be exemplified. Below, with reference to the accompanying drawings, the terminal block 1 illustrated in the drawings is described. .

[0055] <Implementation Method>

[0056] Figure 1 and Figure 2 1 is a perspective view showing an example of the terminal block 1 described in the present application. The terminal block 1 described in the present application is formed in a substantially rectangular parallelepiped shape. It should be noted that in the following description, the direction of the terminal block 1 is Figure 1 or Figure 2The right front side is represented as front (front), the left deep side is represented as back, the left front side is represented as left, the right deep side is represented as right, the upper side is represented as upper, and the lower side is represented as lower. These are directions for the convenience of explanation and are not used to limit the direction when the terminal block 1 is used.

[0057] The terminal block 1 described in the present application has a housing 10 formed in a substantially rectangular parallelepiped shape. On the upper surface of the housing 10, a pull-out component 11 used as a pull rod that can be pulled (pulled out) from the housing 10 is supported on the housing 10 so as to be swingable. The pull-out component 11 is formed in a substantially rectangular shape when viewed from above, with one short side supported on the housing 10, and a locking component 12 used as a lock release buckle assembled on the other short side. An insertion hole 110 into which a wire can be inserted is provided in the pull-out component 11. The terminal portion 130 of the terminal component 13 formed of a conductive material protrudes from the lower surface of the housing 10. Figure 1 The drawing part 11 is shown as an example in which it is pushed into the housing 10. Figure 2 Example from Figure 1 The state shown is the state after the extraction component 11 is pulled up. Figure 1 Indicates the state where the wire is not inserted or the state where the wire is inserted and retained. Figure 2 Indicates the status of inserting wires or removing inserted wires. Figure 1 In the state shown, the locked state is released by pushing the locking member 12 into the side of the pull-out member 11, so that the pull-out member 11 can be pulled up. The wire inserted into the terminal block 1 is electrically connected to the terminal member 13 used as a busbar inside the housing 10, and becomes conductive with the terminal portion 130.

[0058] Figure 3 It is a perspective schematic diagram showing an example of the terminal block 1 according to the present application. Figure 4 The terminal block 1 described in the present application can also be connected to multiple terminals. Figure 1 and Figure 2 The illustrated terminal block 1 into which one wire can be inserted is constructed as a terminal block 1 into which multiple wires can be inserted. The terminal block 1 into which wires can be inserted is constructed based on connectable structural units 1a. One structural unit 1a has various components such as a part of a housing 10, a pull-out component 11, a locking component 12, and a terminal component 13. End surface covers 100 that become the front and back surfaces of the housing 10 are connected to the front and rear ends of the connected multiple structural units 1a. In addition, the connected multiple structural units 1a can be separated. Therefore, by connecting a reasonable number of structural units 1a corresponding to the use and purpose, and connecting the end surface covers 100 at the front and back, a terminal block 1 with a reasonable number of insertion holes 110 can be formed. It should be noted that, if Figure 1 and Figure 2 As an example, the end surface cover 100 may be connected to the front and rear of one structural unit 1a.

Figure 6 It is a perspective exploded schematic diagram showing an example of the internal structure of the terminal block 1 according to the present application. Figure 5 From the perspective of the upper left, the Figure 2 The cross section is a state in which the terminal block 1 is cut along a plane perpendicular to the line segment AB shown. Figure 5 The figure shows a state where the wire is inserted halfway when using a ferrule terminal. The terminal block 1 has various components such as a spring component 14, a linkage component 15, and a shaft component 16 in addition to the housing 10, the pull-out component 11, the locking component 12, and the terminal component 13. The spring component 14 is a component that presses the wire inserted into the housing 10. The linkage component 15 is a component that moves up and down in conjunction with the pull-out component 11 and acts on the spring component 14. The shaft component 16 is a component that serves as a swing axis of the spring component 14.

[0060] Figure 7 It is a perspective exploded schematic diagram showing an example of the housing 10 included in the terminal block 1 according to the present application. Figure 7 The portion of the housing 10 that will become the structural unit 1a is shown separated from the end cover 100 on the front side. Figures 5 to 7 , the housing 10 is described. The housing 10 is formed in a substantially rectangular parallelepiped shape. A wire opening 101 into which a wire can be inserted is provided at the right position of the upper surface of the housing 10, and a linkage component opening 102 into which the linkage component 15 can be inserted so as to move up and down is provided at the left position of the upper surface. A terminal opening 103 for allowing the terminal portion 130 of the terminal component 13 to protrude from the inside to the outside is provided at the right position of the lower surface of the housing 10. Below the linkage component opening 102, a restriction protrusion 104 is formed on the front and rear inner wall surfaces as a linear protrusion that is long in the vertical direction and guides the linkage component 15 to move up and down. A substantially cylindrical support portion 105 that supports the extraction component 11 freely and serves as a swing axis is formed at the right end portion of the upper surface of the housing 10. A locking portion 106 that engages with the locking component 12 and keeps the extraction component 11 in a pushed-in state is formed at the upper left end portion of the inner wall of the housing 10. In addition, a plurality of connecting protrusions 107 and connecting recesses 108 are formed for connecting the structural units 10a of the housing 10 to each other or connecting the structural unit 10a and the end cover 100. Figure 7, an example is shown in which a plurality of connecting protrusions 107 are formed on the front side of the portion of the housing 10 that becomes the structural unit 10a, and a connecting recess 108 is formed on the rear side of the portion of the front surface of the housing 10 that becomes the end cover 100. The connecting protrusions 107 and the connecting recesses 108 are formed at corresponding positions, and by fitting the connecting protrusions 107 into the connecting recesses 108, the structural units 10a can be connected to each other or the structural unit 10a and the end cover 100 can be connected. Figure 7 Although not shown in the figure, a connecting recess 108 is formed on the rear side of the portion of the housing 10 that becomes the structural unit 10 a , and a connecting protrusion 107 is formed on the front side of the portion of the back surface that becomes the end surface cover 100 .

[0061] Figures 8 to 10 It is a perspective schematic diagram showing an example of the pull-out member 11 and the locking member 12 included in the terminal block 1 according to the present application. Figure 8 The pull-out member 11 and the locking member 12 are shown from an oblique upper perspective. Fig. 9 and Fig.10 The pull-out member 11 and the locking member 12 are shown from an oblique downward perspective. Fig.10 A portion of the extraction member 11 is shown to facilitate understanding of the arrangement of the locking member 12. Figure 5 and Figure 6 ,as well as Figures 8 to 10 , the pull-out component 11 and the locking component 12 are described. The pull-out component 11 is a cover that covers the interior of the housing 10 and is disposed on the upper surface of the housing 10. The pull-out component 11 is formed in a substantially rectangular shape when viewed from above, and is provided with a substantially circular insertion hole 110. The insertion hole 110 of the pull-out component 11 is provided at a position corresponding to the wire opening 101 of the housing 10, and the wire is inserted through the insertion hole 110 of the pull-out component 11 and the wire opening 101 of the housing 10. One short side of the pull-out component 11 formed in a substantially rectangular shape when viewed from above engages with the support portion 105 of the housing 10, forming a first locking portion 112 that is axially supported and can swing freely. A fitting chamber 111 into which the locking component 12 is embedded is formed on the end face side of the other short side of the pull-out component 11 that is opposite to the first locking portion 112. The fitting chamber 111 is formed with an opening on the end surface and the lower surface of the pull-out member 11 so that a part of the embedded locking member 12 is exposed. A second locking portion 113 for mounting and linking the linkage member 15 is formed on the lower surface of the pull-out member 11. The pull-out member 11 is pulled up from the upper surface of the housing 10, and swings upward with the support portion 105 of the housing 10 as the swing axis, thereby pulling the locking member 12 side up from the housing 10. The pulled-up pull-out member 11 is pushed into the upper surface of the housing 10, and swings downward with the support portion 105 of the housing 10 as the swing axis, thereby being pushed into the upper surface of the housing 10.

[0062] The locking member 12 is a resin member, and is formed with parts such as an operating portion 120, a locked portion 121, and a force applying portion 122. The operating portion 120 is a portion that receives a push operation from an operator and serves as a lock release buckle, and is exposed to the outside from an opening on the end face side of the pull-out member 11. The locked portion 121 is a portion that engages with the locking portion 106 of the housing 10 to hold the pull-out member 11 in a pushed state, and protrudes downward from an opening on the lower surface side of the pull-out member 11. The force applying portion 122 is a flexible portion that serves as a resin compression spring that applies force to the locking member 12 as a whole toward the outside in the end face direction, and is accommodated in the fitting chamber 111 of the pull-out member 11. When the operator presses the operating portion 120 to push it into the inside of the pull-out member 11, the locked portion 121 is disengaged from the locking portion 106 of the housing 10, and the pull-out member 11 becomes a state in which it can be pulled out. When the operator releases the pressing operation, the force applying portion 122 applies force, and the operating portion 120 returns to the original position. When the operating portion 120 returns to the original position, when the pull-out member 11 is pushed into the upper surface of the housing 10, the locked portion 121 is engaged with the locking portion 106 of the housing 10 and locked to the locking portion 106, so that the pull-out member 11 is in a held state (locked state).

[0063] Fig.11 It is a side schematic diagram showing an example of the appearance of the interlocking member 15 included in the terminal block 1 according to the present application. Fig.12 It is a front schematic diagram showing an example of the appearance of the interlocking member 15 included in the terminal block 1 according to the present application. Fig.13 This is a schematic cross-sectional view showing an example of a cross section of the interlocking member 15 included in the terminal block 1 according to the present application. Fig.13 From the front view, the Fig.11 The cross section of the linkage component 15 is cut by the vertical plane of the CD line segment shown. Figure 5 and Figure 6 ,as well as Figures 11 to 13 , the linkage component 15 is described. The linkage component 15 is a component that moves up and down in linkage with the pull-out component 11. When the pull-out component 11 is pulled out from the upper surface of the housing 10, the linkage component 15 can be moved to the upper top dead center in linkage with the pull-out component 11, and can be moved to the lower bottom dead center when the pull-out component 11 is pushed into the upper surface of the housing 10.

[0064] The linkage member 15 is formed in a substantially quadrangular prism shape, and is formed with a linkage engaging portion 150, a driving cam portion 151, a lower dead center recess 152, an upper dead center recess 153, and a guide groove 154. The linkage engaging portion 150 is a portion engaged with the second engaging portion 113 of the extraction member 11, and is formed in a hook shape at the upper end of the linkage member 15 in order to engage with the second engaging portion 113. The driving cam portion 151 is a cam surface that acts on the spring member 14, and is formed from the center of the right side surface to the lower end. The driving cam portion 151 has a side surface portion 151a parallel to the right side surface, an arcuate recess 151b formed as an arcuate recess in the middle of the side surface portion 151a, and an inclined portion 151c formed as a tapered inclined surface from the right side surface to the lower surface. The spring member 14, which serves as a driven cam, is swung by the action of the linkage member 15, which moves up and down, while being in contact with the side surface 151a, the arc-shaped recess 151b, and the inclined surface 151c of the driving cam portion 151. The lower dead point recess 152 and the upper dead point recess 153 are recesses for engaging with the terminal member 13 and being held at the upper dead point, which is the upper limit of the movement of the linkage member 15, and the lower dead point, which is the lower limit, and are formed at the rear of the right side surface. When the linkage member 15 moves to the upper dead point, the upper dead point recess 153 formed at the lower side engages with the terminal member 13, and when it moves to the lower dead point, the lower dead point recess 152 formed at the upper side engages with the terminal member 13. The guide groove 154 is a portion that engages with the limiting protrusion 104 formed on the inner wall surface of the housing 10 to stabilize the up and down movement, and is engraved on the front surface and the back surface. When the interlocking member 15 is disposed in the housing 10 , the restricting protrusion 104 of the housing 10 engages with the guide groove 154 of the interlocking member 15 . Therefore, the interlocking member 15 is restricted by the restricting protrusion 104 , and the upward and downward movement is stabilized.

[0065] Fig.14 It is a perspective schematic diagram showing an example of the appearance of the terminal member 13 included in the terminal block 1 according to the present application. Fig.15 It is a perspective schematic diagram showing an example of the appearance of the spring member 14 included in the terminal block 1 according to the present application. Fig.16 1 is a perspective view schematically showing an example of the appearance of the terminal member 13, the spring member 14, and the shaft member 16 included in the terminal block 1 according to the present application. Figure 5 and Figure 6 ,as well as Figures 14 to 16 , the terminal component 13, the spring component 14 and the shaft component 16 are described.

[0066] The terminal member 13 is formed in a shape that fits inside the housing 10, and includes a terminal portion 130, a conducting wall 131, a partition wall 132, a fitting wall 133, a connecting wall 134, and a connecting bottom 135. The conducting wall 131 is arranged on the right side of the housing 10, and the lower end thereof extends to the outside of the housing 10 as the terminal portion 130. The conducting wall 131 is arranged on the right side of the housing 10 to sandwich and hold the inserted wire between the spring member 14. The conducting wall 131 and the terminal portion 130 serve as a busbar to conduct the wire held in contact with the conducting wall 131 and other circuits connected to the terminal portion 130. The partition wall 132 is a wall that partitions the space for inserting the wire from the space for configuring the linkage member 15 in the housing 10. A shaft support portion 132a is formed on the upper portion of the partition wall 132, through which the shaft member 16 formed in a rod shape is inserted in the front and rear. A through window 132b is formed below the shaft support portion 132a, through which the spring member 14 passes. A retaining protrusion 132c is formed at the rear end of the partition wall 132, at a position behind the through window 132b, which engages with the bottom dead center recess 152 or the top dead center recess 153 of the linkage member 15 and retains the linkage member 15 at the bottom dead center or the top dead center. The fitting wall 133 is arranged on the left side of the housing 10. The linkage member 15 is fitted between the fitting wall 133 and the partition wall 132 so as to be movable up and down. The connecting wall 134 is a wall connecting the conducting wall 131 and the partition wall 132 from the rear. The connecting bottom 135 is a bottom connecting the partition wall 132 and the fitting wall 133 from the bottom.

[0067] The spring member 14 is formed into a roughly N-shaped shape by bending a flexible material such as a metal sheet at two locations. The spring member 14 is axially supported on the terminal member 13 via a rod-shaped shaft member 16 so as to be swingable. One of the two locations where the spring member 14 is bent is axially supported on the shaft support portion 132a of the terminal member 13 via the shaft member 16, and is a fulcrum portion 140 that serves as a fulcrum for the swinging action. A piece extending obliquely downward from the fulcrum portion 140 to the guide wall 131 side is a pressing piece 141 used as a leaf spring to press the inserted wire. Another piece extending from the fulcrum portion 140 via another bent portion is an engaging piece 142 that engages with the driving cam portion 151 of the linkage member 15 in a state of abutting. The engaging piece 142 extends obliquely downward from the fulcrum portion 140 to the guide wall 131 side, bends to the left, and protrudes to the side of the fitting wall 133 through a through window 132b opened in the partition wall 132 of the terminal member 13. The front end of the engaging piece 142 abuts against the driving cam portion 151 of the linkage cam and is bent into an arc shape to move smoothly. The spring component 14 is axially supported on the axial support portion 132a of the terminal component 13 in a swingable manner, and swings between a holding position where the wire can be held by the pressing piece 141 and a release position where the wire is released from the holding. The weight and shape of the spring component 14 are designed so that when there is no action from other components, the pressing piece 141 side is separated from the abutting position relative to the conducting wall 131 and descends, and the engaging piece 142 side rises according to the balance centered on the fulcrum portion 140.

[0068] The operation of the terminal block 1 formed as described above will be described. Fig.17 and Fig.18 It is a schematic cross-sectional view showing an example of the terminal block 1 according to the present application. Fig.17 and Fig.18 The cross section is shown from the front view so that the driving cam portion 151 of the interlocking member 15 and the spring member 14 abutting against the driving cam portion 151 can be clearly seen. Fig.17 Indicates the state of the wire that can be maintained. Fig.18 Indicates the state in which the wire is inserted or the state in which the inserted wire can be removed.

[0069] exist Fig.17In the illustrated state, the pull-out component 11 is in a position where it has been pushed into the housing 10. The locked portion 121 of the locking component 12 assembled with the pull-out component 11 is engaged with the locking portion 106 of the housing 10, and the pull-out component 11 is maintained in the pushed-in position. The linkage component 15 that is linked to the pull-out component 11 is located at the bottom dead center, and the bottom dead center recess 152 of the linkage component 15 is engaged with and retained in the retaining protrusion 132c of the terminal component 13. The engaging piece 142 of the spring component 14 is retained in the arc-shaped recess 151b of the driving cam portion 151 of the linkage component 15 in the embedded state. When the engaging piece 142 of the spring component 14 is retained in the arc-shaped recess 151b, the front end side of the pressing piece 141 is located in the upper retaining position. Fig.17 In the illustrated state, when no wire is inserted, the tip of the pressing piece 141 of the spring member 14 contacts the conducting wall 131. Therefore, the hole at the center of the rotating member, which is the insertion path for the wire to be inserted, is blocked by the pressing piece 141.

[0070] Fig.18 Indicates that the operator Fig.17 The illustrated state is a state where the operating portion 120 of the locking member 12 is pushed inwardly of the pull-out member 11, the locked state (locked state) of the locked portion 121 of the locking member 12 and the locking portion 106 of the housing 10 is released, and the pull-out member 11 is swung upward (pulled out). Fig.18 In the illustrated state, the pull-out component 11 is in a position where it is pulled out from the housing 10. The linkage component 15 that is linked to the pull-out component 11 is located at the top dead center, and the top dead center recess 153 of the linkage component 15 is engaged with and retained in the retaining protrusion 132c of the terminal component 13. The engaging piece 142 of the spring component 14 moves downward while being in contact with the driving cam portion 151, and is located near the lower end of the inclined portion 151c from the arc-shaped recess 151b through the lower side surface portion 151a. When the engaging piece 142 of the spring component 14 is located near the lower end of the driving cam portion 151, the front end side of the pressing piece 141 is located at the lower release position. Fig.18 In the illustrated state, when a wire is inserted, the wire is released from the pressing of the pressing piece 141 of the spring member 14, so the wire can be easily pulled out. Fig.18 In the illustrated state, when no wire is inserted, the insertion passage for inserting the wire is in an open state, so the wire can be easily inserted. Fig.18 In the illustrated state, the linkage member 15 is held at the top dead center. Therefore, even if the operator does not apply force to the extraction member 11, the terminal block 1 remains Fig.18 The instantiation state will not be restored to Fig.17Therefore, for example, after the operator operates the operation unit 120 with the right hand, the operator can easily perform a one-hand operation of inserting and removing the wire with the right hand and then operating the operation unit 120 with the right hand again.

[0071] exist Fig.18 In the illustrated state, the operator can insert the wire into the housing 10 through the insertion hole 110 opened in the pull-out member 11 and the wire opening 101 opened on the upper surface of the housing 10. In addition, after inserting the wire, the operator pushes the pull-out member 11 into the housing 10 to restore the housing 10. Fig.17 The state of the instantiation. Fig.17 In the illustrated state, the pressing piece 141 of the spring member 14 swings toward the conducting wall 131 side and is located at the holding position, so the pressing piece 141 presses the wire inserted into the housing 10 through the insertion hole 110 and the wire opening 101 toward the conducting wall 131 side. By clamping the wire by the pressing piece 141 of the spring member 14 and the conducting wall 131 of the terminal member 13, the wire is held in contact with the conducting wall 131 in the housing 10, and becomes a state in which it can be conducted with the terminal portion 130.

[0072] For use Fig.17 and Fig.18 The operation of the action described is explained. Figures 19 to 22 It is a perspective schematic diagram showing an example of the appearance of the terminal block 1 according to the present application. Fig.19 The terminal block 1 is shown with no wire inserted and the drawer 11 at a position pushed into the housing 10. The operator releases the locked state by pushing the operating portion 120 of the locking member 12 assembled with the drawer 11 toward the inside of the drawer 11.

[0073] Fig. 20 The operator from Fig.19 The illustrated state is a state where the pull-out member 11 is pulled upward. Fig. 20 and Fig.18 Correspondingly, the wire can be inserted. Fig.21 Indicates that the operator attempted to Fig. 20 The illustrated state is a state where the wire is inserted through the insertion hole 110 formed in the drawer member 11 and the wire opening 101 formed in the upper surface of the housing 10 . Fig. 22 Indicates that the operator Fig.21 The illustrated state is a state where the wire is inserted and the extraction member 11 is pushed into the housing 10 side. Fig. 22 In the illustrated state, the locked portion 121 of the locking member 12 and the locking portion 106 of the housing 10 are in a locked state (locked state), so the pull-out member 11 is held in the pushed-in position and the linkage member 15 is at the bottom dead center. Fig. 22In the illustrated state, the engaging piece 142 of the spring member 14 is held by the driving cam portion 151 of the linkage member 15, and the pressing piece 141 of the spring member 14 sandwiches the wire between the conducting wall 131 of the terminal member 13. The wire is held in contact with the conducting wall 131 in the housing 10, and is in a state where it can be conducted with the terminal portion 130. In this way, the extraction member 11 is used as a lever for operation when plugging and unplugging the wire.

[0074] The terminal block 1 described in the present application is used by being installed on a base such as a substrate or a DIN rail, but the use of the terminal block 1 is not limited to being directly installed on the base. For example, the terminal block 1 can also be installed on the base via the connector 2 using the connector 2 to which the terminal block 1 can be installed. Next, a terminal block device having the terminal block 1 and the connector 2 to which the terminal block 1 can be installed is described.

[0075] Fig.23 and Fig.24 It is a schematic perspective view showing an example of the appearance of the terminal block device 3 according to the present application. Fig.25 It is a perspective cross-sectional schematic diagram showing an example of the internal structure of the terminal block device 3 described in the present application. Fig.23 and Fig.25 This shows the state where the terminal block 1 and connector 2 are separated. Fig.24 The state where the terminal block 1 is mounted on the connector 2 is shown. Fig.25 From the perspective of the upper left, the Fig.23 The cross section is the state after cutting through the vertical plane including the EF line segment.

[0076] like Figure 23 to Figure 25 As shown, the terminal block device 3 includes: a terminal block 1 and a connector 2 to which the terminal block 1 can be mounted. The terminal block device 3 is formed in a rectangular box shape with an open upper surface. The shape of the inner side of the terminal block device 3 is formed by combining with the outer shape of the housing 10 of the terminal block 1 in order to embed the terminal block 1.

[0077] The terminal block 1 used in the terminal block device 3 is formed with an end cover 100 which is the front surface and the back surface of the housing 10, and is used for locking in the state of being embedded in the connector 2. A terminal protection part 100b is formed at the lower part of the housing 10 of the terminal block 1 to protect the terminal part protruding from the housing 10. A through hole 109 is penetrated from the front surface side to the back surface side in the housing 10 of the terminal block 1, and a through component 17 penetrates the through hole 109. The through component 17 is a component that penetrates a plurality of connected structural units 1a and fixes the structural units 1a in the connected state. Fig.25The illustrated through-component 17 is composed of a slender metal pin, and the front end portion is a screw, which is fixed to the end face cover 101 that becomes the terminal end of the through-hole 109. The rear end of the through-component 17 is formed into a shape that is fixed to the entrance portion of the through-hole 109. By allowing the through-component 17 to penetrate the multiple structural units 1a that are connected, the connection state can be firmly maintained. The through-component 17 prevents the multiple structural units 1a that are connected from being separated when the terminal block 1 is installed on the connector 2 or removed from the connector 2. As long as the through-component 17 can fix the multiple structural units 1a that have been connected, the shape for fixing can be appropriately designed. For example, it can be developed into various forms such as a structure in which the rear end side is a screw, a structure in which the two ends are fixed by other components, etc.

[0078] When the connector 2 formed in a box shape with an open upper surface is mounted with the terminal block 1, a locking receiving portion 20 is formed on the inner side surface, which engages with the embedded locking portion 100a of the terminal block 1 and locks the terminal block 1. In addition, the connector 2 has a receiving terminal portion 21 on the inner bottom of the box shape, which is electrically connected to the terminal portion of the terminal block 1 when the terminal block 1 is mounted. A substrate terminal portion 22 is formed on the outer bottom of the connector 2, which is mounted on the substrate and is used to electrically connect to the wiring formed on the substrate. The receiving terminal portion 21 is electrically connected to the substrate terminal portion 22. When the terminal block 1 is mounted on the connector 2 and a wire is inserted into the terminal block 1, the wire is electrically connected to the substrate terminal portion 22 of the connector 2, and is also electrically connected to the wiring formed on the substrate. Figure 23 to Figure 25 The terminal block device 3 shown as an example is a vertical terminal block device 3 in which, when the terminal block device 3 is mounted on a substrate, the direction in which the wire is inserted is substantially perpendicular to the upper surface of the substrate on which the connector 2 is mounted.

[0079] Fig.26 and Fig. 27 It is a schematic perspective view showing an example of the appearance of the terminal block device 3 according to the present application. Fig.26 This shows the state where the terminal block 1 and connector 2 are separated. Fig. 27 The state in which the terminal block 1 is mounted on the connector 2 is shown. Fig.26 and Fig. 27 is to use Figure 23 to Figure 25 Another embodiment of the terminal block device 3 will be described.

[0080] The connector 2 is formed in a box shape with open side surfaces. The terminal block 1 is installed by fitting the terminal portion of the lower surface from the side while being laid flat on the open side surfaces of the connector 2 . Fig.26 and Fig. 27 The illustrated terminal block device 3 is a horizontal type terminal block device 3 in which, when the terminal block device 3 is mounted on a substrate, the direction in which the wire is inserted is substantially parallel to the upper surface of the substrate on which the connector 2 is mounted.

[0081] As described above, the terminal block 1 described in the present application is maintained at the upper dead center when the pull-out component 11 is pulled up and the spring component 14 is moved to the release position. Therefore, even if the operator does not apply a force to the pull-out component 11, the spring component 14 can be maintained in the release position, so that, for example, after the operator operates the operating part 120 with the right hand, it is easy to perform a one-handed operation of plugging and unplugging the wire with the right hand and then operating the operating part 120 with the right hand. That is, the operability can be improved. In addition, when the pull-out component 11 is pushed in, the spring component 14 of the terminal block 1 described in the present application is located in the holding position, and when the pull-out component 11 is pulled out, the spring component 14 is located in the release position. Therefore, it is configured so that when the wire is held, even if the operator's body, tools, and other objects collide with the terminal block 1, it is difficult to move from the holding position to the release position. For example, when the terminal block 1 is configured to move to the release position by pushing, it is easy to move to the release position by collision. Therefore, compared with such a structure, the terminal block 1 described in the present application can prevent the wire from falling out due to erroneous operation or the like.

[0082] The present invention is not limited to the embodiments described above, and can be implemented in other ways. Therefore, the above embodiments are merely illustrative in all aspects and are not restrictive. The technical scope of the present invention is described by the scope of the claims and is not limited to the text of the specification. In addition, deformation and changes within the equivalent scope of the claims are included in the scope of the present invention.

[0083] For example, in the above-described embodiment, a mode in which the insertion hole 110 having a substantially circular shape in a plan view is formed as the insertion hole 110 formed in the pull-out member 11 is shown, but the present invention is not limited to this. Fig.28 It is a perspective schematic diagram showing an example of the terminal block 1 according to the present application. Fig.28 Another embodiment of the terminal block 1 is shown. Fig.28 The illustrated terminal block shows a mode in which the insertion hole 110 opened in the extraction member 11 is formed with a cutout portion 110a. Fig.28 As an example, by forming a cutout portion 110a in the insertion hole 110, when inserting or removing a wire, the wire can be inserted or removed by tilting it toward the cutout portion 110a. In this way, in the terminal block 1 of the present invention, as long as the insertion hole 110 is provided in the pull-out part 11 and the front end of the wire can be inserted into the wire opening 101 of the housing 1 by passing the pull-out part 11, its shape can be appropriately designed. That is, the insertion hole 110 is not limited to a roughly circular shape when viewed from above, and can be formed in various shapes, for example, it can also be as Fig.28 Like the insertion hole 110a in which the cutout portion 110a is formed in the example, it is formed in a partially open shape.

[0084] For example, in the above embodiment, a method of using the pull-out member 11 pivotally supported on a swing shaft to swing is shown, but the present invention is not limited to this, and various methods such as a method of applying force from below to lift the pull-out member 12 to the top can be developed.
