Devices 20 can be separated from each other. In the locking position, the first locking member 65 and the second locking member 75 cannot move with respect to each other, and the first connection portion 60 and the second connection portion 70, and the power control module 30 and the modular electrical device 20 The mutual engagement state is firmly maintained. Furthermore, the 1st latching member 65 and the 2nd latching member 75 are comprised so that the 1st connection part 60 and the 2nd connection part 70 may be mutually compressed in the latching position. This can be achieved by configuring the first locking member 65 and the second locking member 75 to engage with each other with an interference fit.

  Thus, when the first locking member 65 and the second locking member 75 are in the locked position, the power control module 30 and the modular electrical device 20 are compressed or clamped, and the power control module 30 and the modular electrical device 20 are A single integrated assembly. Thus, the advantage of the power control module 30 and the modular electrical device 20 is that, in use, the integrated integrated device sensation in which play between the power control module 30 and the modular electrical device 20 is substantially eliminated. The power control module 30 and the modular electric device 20 have the above. Thus, in embodiments where the power control module 30 includes a handle that exerts a force on the combination of the power control module 30 and the modular electrical device 20, for example, pressure is applied to the workpiece through the handle of the power control module 30 and the modular electrical device 20. , It gives the user an integrated and integrated device sensation and allows accurate work on the workpiece.

  When the first connection member 62 and the second connection member 72 are engaged, the power control module 30 and the modular electrical device 20 are subsequently tilted with respect to each other, and the first connection axis X and the second connection axis Y are moved with respect to each other. Move or pivot in an arc. As a result, as shown in FIGS. 1, 4, 7, 8, and 16, the first locking member 65 and the second locking member 75 are circular with respect to each other from the separated position until they are engaged with each other at the locking position. Move or pivot in an arc. In the locking position, the first locking member 65 and the second locking member 75 are movable with respect to each other between the locking position and the non-locking position, whereby the locked state and the non-locking state respectively. I will provide a. In the locked state, the first locking member 65 and the second locking member 75 are locked and compressed, and in the non-locked state, the first locking member 65 and the second locking member 75 are free to each other. Moving.

The first locking member 65 and the second locking member 75 are moved relative to each other from the locking position to the non-locking position, whereby the state of the first locking member 65 and the second locking member 75 is locked. This is accomplished by changing from a non-locked state. Subsequently, when the power control module 30 and the modular electrical device 20 are tilted with respect to each other, the first connecting shaft is separated from each other by an arc or a pivoting movement to the position shown in FIGS. X and the second connecting axis Y move. When the power control module 30 and the electric device 20 are tilted and the first connection shaft X and the second connection shaft Y are moved away from each other, the first locking member 65 and the second locking member 75 are also separated from each other. Move or pivot in an arc. Then, the module 30 and the electric device 20 are pulled away from each other in a state where the first connection shaft X merges with the second connection shaft Y, and the first connection member 62 and the second connection member 72 are disengaged from each other. Move to the position shown in FIG.

  In another form of the connection device 50 (not shown), the first connection portion 60 includes a set of first locking members 65.

The Thereby, separation of the first locking member 65 and the second locking member 75 is prevented.

  In the embodiment shown in FIGS. 7-16, the first locking member 65a comprises a hook in the form of a plate 66a having a plurality of openings 67a arranged in a row. The second locking member 75a includes an anchor in the form of a base 77a having a plurality of hook members 78a arranged in a row and extending from the base 77a. The hook member 78a includes an upright portion 79a extending from the base 77a and a transverse portion 80a extending forward from the upright portion 79a. The crossing 80a has a tapered edge 82a facing the base 77a. Thus, each hook member 78a defines a slot 81 extending forward between the base 77a and the tapered edge 82a of the transverse portion 80a. The tapered edge 82a of the transverse portion 80a provides the slot 81 with a tapered cross section such that the slot 81 has an open end 85a and an opposite closed end 86a. The open end 85a has a wider width than the closed end 86a. The slot 81a gradually narrows from the wide open end 85a to the narrow closed end 86a.

  Each of the hook members 78a of the second locking member 75a is configured to be received in a respective one of the openings 67a of the sheet 66a of the first locking member 65a. However, the plate 66a and the plurality of openings 67a of the first locking member 65a are linearly movable in the front-rear direction with respect to the housing 22 of the device 20. The plate 66a and the plurality of openings 67a are biased by a biasing member 90a toward a stationary position in the rearward direction where the opening 67a is not aligned with the hook member 78a and cannot accept the hook member 78a therein. Yes. The biasing member 90a may be a helical spring or any other form of biasing member. The first locking member 65a can pivot between a position where the detent 64a contacts the contact surface 63a of the plate 66a and a position where the detent 64a does not contact the contact surface 63a. A pivot detent 64a is provided. When the detent 64a abuts against the abutment surface 63a, the detent 64a maintains the plate 66a at a position before the stationary position and opposes the urging force applied by the urging member 78a. Then, the opening 67a of the sheet 66a of the first locking member 65a is aligned with the hook member 78a of the second locking member 75a. When the hook member 78a is aligned with the opening 67a, the hook member 78a can be received through the opening 67a of the seat 66a of the first locking member 65a. When the hook member 78a is received in the opening 67a, one of the hook members 78a engages with the detent 64a and moves so as not to contact the contact surface 63a, and the biasing member 78a moves the plate 66a to a later rest position. And will be able to move.

  In another form (not shown), a tapered surface may be provided that engages the surface of the plate 66a surrounding one of the openings 67a. The tapered surface drives the plate 66a to a position where the opening 67a of the first locking member 65a is aligned with the hook member 78a and receives the hook member 78a, against the biasing force applied by the biasing member 90a.

  When the hook member 78a is first received in the opening 67a, the first locking member 65a, the second locking member 75a, and the plate 66a are in the front positions, and the first locking member 65a and the second locking member 75a are in the previous position. Are in an unlocked position relative to each other. After the hook member 78a is received in the opening 67a, the plate 66a and the plurality of openings 67a move linearly relative to the hook member 78a toward the rear position due to the biasing force applied by the biasing member 90a. Can do. As shown in FIG. 16, when the plate 66a and the opening 67a are in the rear position, an edge region 68a adjacent to each of the openings 67a is received in each one of the slots 81 extending forward of the hook member 78a. When the edge region 68a adjacent to each of the openings 67a is received in each one of the slots 81a, the first locking member 65a and the second locking member 75a are locked. When in the locked state, the first locking member 65a and the second locking member 75a are prevented from moving relative to each other, thereby locking the first locking member 65a and the second locking member 75a.

  As the plate 66a begins to move toward the rear position, the edge region 68a of the opening 67a is initially received through the open end 85a of the slot 81a. However, as the plate 66a continues to move further toward the rear position, the tapered edge 82a begins to engage the edge region 68a of the opening 67a. When the plate 66a further moves toward the rear position, the tapered edge 82a engages with the edge region 68a of the opening 67a in a state where the force is increased in a direction orthogonal to the direction in which the plate 66a moves relative to the hook member 78a. . In other words, the tapered edge 82a engages with the edge region 68a of the opening 67a with an interference fit. This is because the plate 66a is fixed to the first connection portion 60 of the housing 22 of the electric device 20 by the movement orthogonal to the movement direction of the plate 66a with respect to the hook member 78a, and the movement direction of the plate 66a with respect to the hook member 78a This is because the hook member 78 a is fixed to the second connection portion 70 of the housing 32 of the power control module 30 by the movement in the orthogonal direction.

  As a result of the movement of the plate 66a of the first locking member 65a in the rearward direction with respect to the hook member 78a of the second locking member 75a, the edge region 68a of the opening 67a of the plate 66a and the tapered edge 82a of the hook member 78a. Abut. As a result of the contact between the edge region 68a of the opening 67a of the plate 66a and the tapered edge 82a of the hook member 78a, relative movement between the first locking member 65a and the second locking member 75a is prevented. Since the edge 82a of the hook member 78a is tapered, the engagement force between the edge 82a of the hook member 78a and the edge region 68a of the opening 67a of the plate 66a is moved by applying a force to the plate 66a and moving it backward. And thereby a compressive force can be applied between the first connection 60 of the housing 22 of the electrical device 20 and the second connection 70 of the housing 32 of the power control module 30. In this way, the first locking member 65a and the second locking member are compressed so that the first connection part 60 of the housing 22 of the electrical device 20 and the second connection part 70 of the housing 32 of the power control module 30 are compressed together. A member 75a is configured. When the first locking member 65a and the second locking member 75a are in the locked position, the power control module 30 and the modular electrical device 20 are compressed or clamped, and the power control module 30 and the modular electrical device 20 are united. Into an integrated assembly.

  When the power control module 30 and the device 20 need to be separated from each other, the first connection 60 and the second connection 70 must be separated. A button 97 a is disposed at the rear end 35 of the handle portion 34. The button 97a is mechanically coupled to the plate 66a and the plurality of openings 67a of the first locking member 65a. When the button 97a is pressed, the plate 66a and the plurality of openings 67a are driven forward toward a position where the opening 67a of the first locking member 65a is aligned with the hook member 78a. When the opening 67a of the first locking member 65a is aligned with the hook member 78a, the power control module 30 and the device 20 are inclined with respect to each other, and the first locking member 65 and the second locking member 75 are connected to the first connection member. 62 and the second connection member 72 are pivoted to the separation position shown in FIGS. When the hook member 78a is removed from the opening 67a of the seat 66a of the first locking member 65a, the hook member 78a releases the detent 64a. The detent 64a is biased to abut against the abutment surface 63a of the seat 66a, and the plate is in a front position ready for reinsertion of the hook member 78a into the opening 67a of the seat 66a of the first locking member 65a. 66a is held.

  In another form of the connection device 50 (not shown), the first connection portion 60 includes a set of first locking members 65a in the form of a set of plates 66a each having a plurality of openings 67a arranged in a row. The pair of first locking members 65 a are arranged along the first connection axis X so as to be separated from each other. The second connection portion 70 includes a set of second locking members 75a in the form of a set of bases 77a each having a plurality of hook members 78a arranged in a row and extending from the base 77a. The pair of second locking members 75a are disposed away from each other along the second connection axis Y. The connection device 50 moves the module 30 and the electrical device 20, the first connection unit 60 and the second connection unit 70 toward each other in a direction substantially orthogonal to the first connection axis X and the second connection axis Y, and By connecting the first locking member 65a and the pair of second locking members 75a to the locking position, the connection between the power control module 30 and one of the modular electrical devices 20 is facilitated. The set of first locking members 65a and the set of second locking members 75a function in substantially the same manner as the locking members 65a and 75a described above. In the locking position, when the first connection portion 60 and the second connection portion 70 are coupled to each other, the pair of first locking members 65 and the pair of second locking members 75 are moved into the locking position and the non-locking position. Can move between each other. In the locking position, the first connection part 60 and the second connection part 70 are locked and compressed, and in the non-locking position, the first connection part 60 and the second connection part 70 are separable.

  In the embodiment shown in FIGS. 17-19, the module assembly comprises a connection device that releasably connects the electrical device 20 and the power control module 30. The connection device includes a first connection unit 60 and a second connection unit 70. The first connection part 60 includes a first connection member 62 and a first locking member 65b. The first locking member 65 b is disposed away from the first connection member 62 along the first connection axis X. The second connection portion 70 includes a second connection member 72 and a second locking member 75b that is disposed away from the second connection member 72 along the second connection axis Y. The connection apparatus moves the module 30 and the electrical device 20, the first connection part 60 and the second connection part 70 toward each other in a state where the first connection axis X merges with the second connection axis Y, and FIGS. , 9, 10, and 15 to engage the first connecting member 62 and the second connecting member 72, thereby connecting the power control module 30 to one of the modular electrical devices 20. make it easier.

  When the first connection member 62 and the second connection member 72 are engaged, the power control module 30 and the modular electrical device 20 are subsequently tilted with respect to each other, and the first connection axis X and the second connection axis Y are moved with respect to each other. Move or pivot in an arc. As a result, the first locking member 65b and the second locking member 75b are separated until they are engaged with each other at the locking position, as shown in the embodiment of FIGS. 1, 4, 7, 8, and 16. Move or pivot in an arc from each other. In the locking position, the first locking member 65b and the second locking member 75b are movable with respect to each other between the locking position and the non-locking position, whereby the locked state and the non-locking state respectively. I will provide a. In the locked state, the first locking member 65b and the second locking member 75b are locked and compressed, and in the unlocked state, the first locking member 65b and the second locking member 75b are free with respect to each other. Moving.

  The connection device 50b also facilitates the separation of the power control module 30 and the modular electrical device 20. The first locking member 65b and the second locking member 75b are moved relative to each other from the locking position to the non-locking position, whereby the state of the first locking member 65b and the second locking member 75b is locked. This is accomplished by changing from a non-locked state. Subsequently, when the power control module 30 and the modular electrical device 20 are tilted with respect to each other, the first connecting shaft is separated from each other by an arc or a pivoting movement to the position shown in FIGS. X and the second connecting axis Y move. When the power control module 30 and the electric device 20 are tilted and the first connection shaft X and the second connection shaft Y are moved away from each other, the first locking member 65b and the second locking member 75b are also separated from each other. Move or pivot in an arc. Then, when the module 30 and the electric device 20 are pulled away from each other in a state where the first connection shaft X merges with the second connection shaft Y, the first connection member 62 and the second connection member 72 move out of engagement.

  In the embodiment shown in FIGS. 17-19, the first locking member 65 b includes a catch 66 b that stands upright from the first connection surface 61 of the first connection portion 60. The hook 66b comprises an upstanding part 63b and a transverse part 68b in the form of an elongated ridge depending from the upright part 63b. The transverse portion 68 b has a first contact surface 64 b that faces the first connection surface 61 and is substantially parallel to the first connection surface 61. The first contact surface 64 b may be parallel to the first connection surface 61 or may be inclined with respect to the first connection surface 61. A groove 67b is defined between the crossing portion 68b and the first connection surface 61. The crossing portion 68 b has a tapered edge or an inclined edge 69 b that faces away from the first connection surface 61 and is inclined with respect to the first connection surface 61. The second locking member 75 b of the second connection portion 70 comprises an anchor in the form of an elongated ridge 74 b that defines an elongated recess 77 b in the second connection surface 71. The elongated recess 77b has an upright recess 78b and a transverse recess 79b depending from the upright recess 78b. The transverse recess 79 b has a second contact surface 80 b that is located below the second connection surface 71 and faces away from the second connection surface 71.

  Once the first connection portion 60 and the second connection portion 70 are engaged, the first locking member 65b and the second locking member 75b are in the locking position. In the locking position, the hook 66b of the first locking member 65b is located in the recess 77b of the second locking member 75b. In the locking position, the first locking member 65b and the second locking member 75b are movable relative to each other between the non-locking position and the locking position. In the non-locking position, the upright portion 63b and the transverse portion 68b of the first locking member 65b are located in the upright concave portion 78b of the second locking member 75b. In the locking position, the upright portion 63b of the first locking member 65b is positioned in the upright recess 78b of the second locking member 75b, and the transverse portion 68b of the first locking member 65b is crossed by the second locking member 75b. It is located in the recess 79b. As a result, the first contact surface 64b and the second contact surface 80b face each other and contact each other. The first contact surface 64 b may be inclined with respect to the first connection surface 61. As a result, a compressive force or a larger compressive force is applied between the first connecting surface 61 and the second connecting surface 71 when in contact with the second contact surface 80b. In the non-locking position, the first locking member 65b and the second locking member 75b are movable with respect to each other, and the first connection portion 60 and the second connection portion 70, the power control module 30 and the modular electric device 20 are moved. Can be separated from each other. In the locking position, the first locking member 65b and the second locking member 75b cannot move relative to each other, and the first connection portion 60, the second connection portion 70, the power control module 30, and the modular electric device. 20 are firmly held in engagement with each other. Further, the first locking member 65b and the second locking member 75b are configured so that the first connection portion 60 and the second connection portion 70 are compressed together at the locking position.

  The first connection member 62 and the second connection member 72 are engaged, and the power control module 30 and the modular electrical device 20 are tilted with respect to each other, so that the first locking member 65b and the second locking member 75b are relative to each other. The first locking member 65b is urged by an urging means such as a spring toward the position where the contact surface 81b is engaged by the inclined edge 69b of the hook 66b. The second connection surface 71 includes an inclined contact surface 81b located adjacent to the upright recess 78b. When the first locking member 65b and the second locking member 75b continue to move toward each other, the inclined edge 69b of the hooking portion slides on the inclined contact surface 81b, and the biasing force acting on the first locking member 65b is applied. On the contrary, the inclined edge 69b of the hook portion acts so as to pass through the inclined contact surface 81b. When the inclined edge 69b passes through the inclined contact surface 81b, the upright portion 63b and the transverse portion 68b of the first locking member 65b can enter the upright concave portion 78b of the second locking member 75b. When the first locking member 65b and the second locking member 75b continue to move toward each other, the first locking member 65b is moved to the extent that the transverse portion 68b of the first locking member 65b reaches the transverse recess 79b of the second locking member 75b. The upright portion 63b and the transverse portion 68b of the one locking member 65b enter the upright concave portion 78b. Subsequently, the transverse portion 68b of the first locking member 65b is urged into the transverse recess 79b of the second locking member 75b by the urging force, and the first contact surface 64b and the second contact surface 80b face each other and come into contact with each other. And abut against each other. As a result, the first locking member 65b and the second locking member 75b are in the locking position. More specifically, this is a locking position where both the first locking member 65b and the second locking member 75b are locked.

  When the power control module 30 and the device 20 need to be separated from each other, the first connection 60 and the second connection 70 must be separated. A button 97b on one of the side surfaces 31, 33 of the handle 34 is mechanically coupled to the first locking member 65b. When the button 97b is pressed, the first locking member 65b operates against the biasing force acting on the first locking member 65b, and the first locking member 65b moves from the locking position to the non-locking position. . Subsequently, the power control module 30 and the modular electrical device 20 are tilted with respect to each other, so that the first locking member 65b and the second locking member 75b are arcuate with respect to each other from the locking position to the separation position. Move or pivot to. Subsequently, the first connection member 62 and the second connection member 72 are disengaged, thereby completely separating the power control module 30 and the modular electrical device 20.

  The power control module 30 has a trigger lock that prevents the operation of the trigger 38 unless the first connecting portion 60 and the second connecting portion 70 are coupled and the first locking member 65 and the second locking member 75 are locked to each other. Prepare. The trigger lock also has a function of preventing the operation of the trigger 38 when the buttons 97a and 97b are pressed and the power control module 30 and the device 20 are separated from each other. The trigger lock that prevents manipulation of the trigger 38 may take any suitable form. In the embodiment shown in FIGS. 7-16, the trigger lock that prevents operation of the trigger 38 is in the form of a pivot member 95a that pivots back and forth as the plate 66a having a plurality of openings 67a moves back and forth. When the plate 66a is in the forward position, the pivot member 95a abuts the rear surface of the trigger 38, and the trigger 38 is lowered and current from the power source to the motor 19 of the device 20 or other electrically functional components via the cable 52 is reduced. Prevent transmission. When the plate 66a is in the rear position, such as when the first locking member 65a and the second locking member 75a are in the locked state, the pivot member 95a does not contact the rear surface of the trigger 38, and the trigger 38 , And the transmission of current from the power source to the motor 19 of the device 20 or other electric functional parts via the cable 52 becomes possible. In the embodiment of FIGS. 17-19, the trigger lock is in the form of a push member 95b in the first connection surface 61 of the power control module 30. The pressing member 95b engages with the protrusion 96b on the second connection surface 71 of the electrical device 20 when the first connection portion 60 and the second connection portion 70 are engaged. The trigger 38 can operate only when the pressing member 95b is pushed by the protrusion 96b when the power control module 30 and the electric device 20 are engaged with each other. Further, the power control module engages when the button 97b for releasing or releasing the first locking member 65b and the second locking member 75b is pressed, and the second control lock ( (Not shown). In the second trigger lock, when the trigger 38 is operated, that is, when the trigger 38 is pressed by the user's finger, the button 97b for releasing or releasing the first locking member 65b and the second locking member 75b is pressed. It also has a function to prevent this.

  In each illustrated embodiment, the first connection portion 60 includes a first electrical contact 69 disposed in a recess 68 in the first connection surface 61 of the housing 32 of the module 30. Contacts 69 are disposed in the recesses 68 to prevent the user from accessing or at least inadvertently touching the contacts 69 when the module 30 is disconnected from the device 20. The second connection part 70 includes a second electrical contact 79 protruding from the second connection surface 71 and standing upright. When the first connection portion 60 is coupled to the second connection portion 70 in the above-described manner, the second contact 79 is configured to engage with the first electrical contact 69 fitted in the recess 68. The first electrical contact 69 of the module 30 is in electrical contact with the switch assembly of the module 30 and the second electrical contact 79 is in electrical contact with the motor 19 of the device 20 or any other electrically functional component. Thus, when the first electrical contact 69 and the second electrical contact 79 are engaged with each other, the switch assembly is activated by manual operation of the trigger 38, and the motor 19 or other electric motor of the device 20 is connected from the power source via the cable 52. Current is transmitted to the functional component, thereby actuating the device 20.

  In the embodiment shown in FIGS. 1-6, 17-19, the first connecting member 62 comprises an elongated slot 64 extending in the direction Q, and the second connecting member 72 is in the form of a raised portion 74 extending generally in the direction R. It is. Further, the first locking members 65 and 65b are in the form of hooks 66 and 66b having elongated openings 67 or grooves 67b in the direction of the axis Q, and the second locking members 75 and 75b are in the direction of the axis R. An anchor in the form of a rod 77 or ridge 74b that defines an elongated recess 77b. When the first connecting portion 60 and the second connecting portion 70 are coupled, the raised portion 74 is fitted into the slot 64, and the first locking members 5, 65b and the second locking members 75, 75b are engaged with each other. The connecting member 62 and the second connecting member 72 are engaged with each other. As a result, when the first locking members 5, 65b and the second locking members 75, 75b move to the locking position, the elongated openings 67 or the grooves 67b of the hook portions 66, 66b become the second locking members 75, 75b. The rod 77 or the raised portion 74b of the first member is received. In this position, the first connection surface 61 is in a position facing the second connection surface 71.

  An advantage of the above-described embodiment of the present invention is that the first connecting member 62 and the second connecting member 72 contact and engage with each other along the elongated overall length in directions Q and R. When the first connection member 62 and the second connection member 72 are in contact, the directions Q and R are the same direction. Further, the first locking members 65, 65a, 65b and the second locking members 75, 75a, 75b are brought into contact with each other and engaged with each other along the elongated total length in the directions Q and R. Thus, when the user operates the assembled electrical device 20 and the power control module 30 by grasping the handle 34 and applies a force to the handle 34 in the direction from the rear portion 35 to the front portion 36 of the handle, the elongated shape in the directions Q and R is obtained. Along the entire length, the force along the connection between the first connecting member 62 and the second connecting member 72 and the connection between the first locking members 65, 65a, 65b and the second locking members 75, 75a, 75b. Is transmitted to the device 20. If it does so, between the 1st connecting member 62 and the 2nd connecting member 72, and between the 1st locking members 65, 65a, and 65b and the 2nd locking members 75, 75a, and 75b, it is in each elongate full length. A load spreads along. In addition, any load applied in the lateral direction of the handle 34 in the direction along the axis X transmits the load from the handle 34 to the device 20 or from the device 20 to the handle 34. The load spreads along the elongated overall lengths of the first connecting member 62 and the second connecting member 72, and the first locking members 65, 65a and 65b and the second locking members 75, 75a and 75b.

  As shown in FIGS. 1-5, 7, 9, 11, 15, 16, the trigger mechanism 38 includes a dial 38a connected to the device. When the power control module 30 and the electric device 20 are assembled as shown in FIGS. 1, 4, 7, 8, and 16, the dial 38 a has a current and / or voltage from the power source to the electric functional component of the electric device 20. Change the flow. The device that changes the current or voltage from the power source to the electrical device 20 may be any device suitable for this purpose and is configured to change its resistance value without interrupting the connected circuit. A resistor (known as a variable resistor). The dial 38a can be operated by the user to adjust the variable resistor to change the current from the power source to the electrical device 20.

  The first electrical contact 69 includes three separate contacts disposed in the recess 68 in the first connection surface 61 of the housing 32 of the power control module 30. One of the electrical contacts is a negative electrode and the other two positive electrodes. One of the positive electrodes receives current in an on / off manner, while the other positive electrode receives variable current and / or voltage from the trigger mechanism 38. The second connection unit 70 includes a second electrical contact 79. However, the second electrical contact 79 includes two electrical contacts. One is in contact with the negative electrode and the other is in contact with any one of the positive electrodes to receive current in an on / off manner, or receive a variable current or voltage. The configuration described above allows the power control module 30 to be coupled with various modular electrical devices 20, and the trigger mechanism 38 powers in either an on / off format or a variable format to match the electrical device 20. It becomes possible to supply.

  Unlike the AC power of the above-described embodiments, in another form of a power control module (not shown) comprising an integral or removable power battery that provides DC power, the first electrical contact is on the housing of the power control module. Five separate contacts arranged in a recess in the first connection surface are provided. The two electrical contacts function as positive and negative electrodes that provide reversible power to the tool module, for example, to provide a normal and reverse mode of the tool module. The other two terminals function as a positive electrode and a negative electrode for another electric device module connected to the power control module, such as a light emitting device. The other terminal functions as a means for providing a sensor signal to the charger when the power control module is attached to the charger that charges the battery. The terminal provides information on the amount of charge of the battery to the charger. The terminal may be connected to the battery to provide battery voltage information or battery resistance information. Alternatively, the terminal may be connected to a sensor such as a temperature sensor to provide battery charging information.
