Description

[0001]
BACKGROUND OF THE INVENTION
The present invention enables electrical connection devices arranged at various locations in a ship to be connected / disconnected only when the switch is in a circuit disconnected state when connected to a plug on the electrical equipment side. The present invention relates to a waterproof electrical connection device for ships with a switch for turning on and off.
[0002]
[Prior art]
In general, an electrical connection device consisting of plugs and socket outlets for connecting and disconnecting electrical circuits installed and used in ships, so that the electrical outlets can be connected and disconnected without plugging or unplugging. Some have their own switches. In order to ensure its safety, for example, by locking a part of the switch handle to the plug after insertion at the turning connection position of the rotary switch, a lock that prevents the plug from being removed when the circuit is connected Some have a mechanism.
[0003]
In addition, there is a built-in interlock mechanism that allows the switch operation only when the plug is connected, connects / disconnects the plug when the switch is turned on, and disables the switch operation when the switch is not connected. Conventionally, as the interlock mechanism, for example, a plug retaining plate is provided on the switch shaft, a link linked to the switch is inserted, a gear linked to the switch is used, When the insertion position is turned to one side, it is “twisted”, and when it is turned to the other side, it is “twisted”, or it has an electrical configuration with a pilot contact.
[0004]
[Problems to be solved by the invention]
However, according to the conventional locking mechanism described above, even when the plug is inserted and connected and the plug is prevented from being removed when the switch is in the on state, the plug can be inserted and removed only when the switch is in the off state. It is only possible to do this, and the circuit can be disconnected and connected by the switch alone, so that it is not always possible to achieve sufficient safety.
[0005]
In addition, the above-mentioned interlock mechanism is easy to cause a ground fault and a short circuit due to an arc because the plug is directly inserted into and removed from the socket outlet, and there is a possibility that the contact may be hindered in use. Even when the plug is not connected, the operation such as being able to turn on the switch may be uncertain. Not only that, the switch shaft with a plug retaining plate can operate the switch alone, and those with links and gears that interlock with the switch can be operated quickly to ensure safety. It is not linked to the quick cut operation during cutting.
[0006]
Therefore, the present invention was created in view of the conventional circumstances as described above, and in a socket outlet incorporating a switch, a plug can be inserted / removed only at a circuit cutting position of the switch by a mechanical interlock mechanism. In addition, it is possible to improve the safety and reliability by disabling the switch connection when the plug is not fully inserted, and at the time of connection connection / disconnection operation with the switch handle, the switch is quickly turned on / off and contacted. An object of the present invention is to provide a waterproof electrical connection device for a ship with a switch that is excellent in reducing damage and improving durability.
[0007]
[Means for Solving the Problems]
In order to achieve the above-described object, in the present invention, the substantially box-shaped outlet body 1 and the plug 80 are inserted at a specific position via the guide means (15, 85), and the electrode pin 83, the ground electrode. An outlet body 10 having a contact mechanism 11 having an electrode contact 13 and a ground electrode contact 14 into which a pin 84 is inserted, and being fixed to the outlet main body 1, and swinging and rotating for circuit disconnection and connection. A switch mechanism 20 having a switch 21 that is operated by a switch handle 22 and fixed to the outlet body 1, and an interlock mechanism 70 that allows the switch mechanism 20 to be operated only when the plug 80 is inserted. The interlock mechanism 70 is arranged so as to be swingable and rotatable around the outlet body 10. When the switch handle 22 is swung, the driven ring 71 having a locking portion 73 that can be locked to the guide means (85) of the plug 80 that is swung and inserted into the outlet body 10 and the plug 80 are removed. Locking means 76 that is locked to the driven ring 71 and that slides when the plug 80 is inserted and is released from the driven ring 71 is provided.
The driven ring 71 is formed in the shape of a donut plate surrounding the outlet body 10, and an engagement protrusion that engages with a drive cam 32 that is linked to the switch handle 22 and is oscillated at the peripheral portion on the switch mechanism 20 side. And a locking portion 73 that locks by swinging rotation of the driven ring 71 itself on the upper surface of the guide means (85) for inserting the plug 80 into the outlet body 10 at a specific position. A lock groove 74 is formed in a notch shape on the lower surface that is separated from the stop portion 73 by an angle of the swinging range.
The lock means 76 is arranged at a position corresponding to the position of the guide means (85) of the plug 80 to be inserted into the outlet body 10, and is elastically urged to project toward the insertion side of the plug 80 as being pressed by the plug 80. In this state, a lock key 78 that is detachably engaged with the driven ring 71 is slidably disposed via a slide guide.
Further, the switch mechanism 20 is provided with a quick-on / fast-off means 31. The fast-on / off means 31 follows a swing of the switch handle 22 and swings and rotates between the connection position and the cutting position. A cam 32, a lock cam 42 that is oscillated and rotated between the connection position and the cutting position and linked to the switch 21, a connection position stopper 51 that stops the lock cam 42 at the connection position, and a cutting position that stops at the cutting position The stoppers 56 are connected to each other between the drive cam 32 and the lock cam 42, and a torsional / repulsive force is applied as the drive cam 32 swings. When the elastic force is released, the lock cam 42 is displaced from the cutting position to the connecting position, and when the drive cam 32 reaches the cutting position, the torsional elastic force is released and the lock cam 42 is released. 42 are those formed by a torsion spring 61 is displaced to the cutting position from the connection position.
The drive cam 32 is connected to the switch handle 22, and has a protruding piece-like stopper pressing protrusion 34 that presses and immerses each of the connection position stopper 51 and the cutting position stopper 56 against the resilience force on the outer peripheral edge. A spring engaging protrusion 35 that engages one end of the torsion spring 61, and a rocking link portion 38 that engages the driven ring 71 of the interlock mechanism 70.
The lock cam 42 is arranged coaxially with the drive cam 32 so as to be slidable and slidable with respect to the drive cam 32. The lock cam 42 is fixed at the connection position to be locked to the connection position stopper 51 and the cutting position stopper 56 on the outer periphery. The groove 43 and the cutting position fixing groove 44 are formed in a notch shape, and have a spring engagement protrusion 45 that engages the other end of the torsion spring 61.
[0008]
In the waterproof electrical connection device for a ship with a switch according to the present invention configured as described above, when the plug 80 is inserted into the outlet body 10, it is performed at a specific position via the guide means (15, 85). The subsequent plug 80 releases the locking means 76 in the interlock mechanism 70 from the driven ring 71, and the driven ring 71 that has been locked swings and rotates the drive cam 32 of the switch mechanism 20 and swings the switch handle 22 and the like. To make it possible.
The swinging operation of the switch handle 22 in the switch mechanism 20 is performed by instantaneously switching and displacing the internal contact of the switch 21 via the quick turn-on / off switch 31 to connect or disconnect the circuit and simultaneously via the interlock mechanism 70. The plug 80 is locked in the inserted state to prevent the plug 80 from being pulled out, or the lock is released to allow the plug 80 to be pulled out.
In the quick entry / speed-off means 31, the synchronized rotation of the drive cam 32 accompanying the swing operation of the switch handle 22 is caused by the lock cam 42 that is stopped by the connection position stopper 51 or the cutting position stopper 56 at one end. The other end of the torsion spring 61 is moved so that the torsion spring 61 accumulates the torsional elastic force, and the drive cam 32 that is oscillated and rotated as it is is either the cutting position stopper 56 or the connection position. The stopper 51 is reached, and the lock cam 42 is unlocked. Then, the torsional repulsion force of the torsion spring 61 forcibly causes the lock cam 42 to swing and rotate instantaneously, and the internal contact of the switch 21 connected to the lock cam 42 is displaced and switched to connect or disconnect the circuit. The locking cam 42 is stopped and held at the connection position or the cutting position by being engaged with the connection position stopper 51 or the cutting position stopper 56.
When the circuit is connected by swinging the switch handle 22 from the cutting position to the connecting position when the plug 80 is inserted, the driven ring 71 is driven by the interlocking mechanism 70 by the swinging rotation of the drive cam 32 of the quick-on / fast-off means 31. And the locking portion 73 is locked to the guide means (85) of the plug 80 to prevent the plug 80 from being removed. Similarly, the drive cam 32 oscillating and rotating is locked to the cutting position stopper 56 and pressed against the torsion spring 61 while torsionally applying a torsion spring 61 to the torsion spring 61. The protrusion 34 is brought to the cutting position stopper 56. Then, the lock cam 42 is unlocked by the cutting position stopper 56, and the lock cam 42 is forcibly and instantly swung by the torsional elastic force of the spring 61, and the internal contact of the switch 21 is connected. It is displaced to a position and locked by a connection position stopper 51 to hold the connection position.
When the circuit is disconnected by swinging the switch handle 22 from the connection position to the disconnection position, the swinging drive cam 32 is locked with the connection position stopper 51 and screwed between the lock cam 42 at the connection position. The stopper pressing protrusion 34 is brought to the connection position stopper 51 while torsionally imparting the elastic force to the torsion spring 61. Then, by releasing the locking state of the lock cam 42 by the connection position stopper 51, the lock cam 42 is forcibly and instantaneously swung and rotated by the torsional elastic force of the spring 61, and the internal contact of the switch 21 is disconnected. It is displaced to a position and locked by a cutting position stopper 56, and the cutting position is held.
The drive cam 32 that is displaced to the cutting position also causes the driven ring 71 of the interlock mechanism 70 to swing and rotate to release the locking portion 73 from the guide means (85) of the plug 80 so that the plug 80 is removed. Make it possible. When the plug 80 is removed, the lock key 78 of the locking means 76 is engaged with the lock groove 74 of the driven ring 71 to prevent the driven ring 71 from rotating and rotating, and the plug 80 is not inserted into the outlet body 10. The drive cam 32 that is continuously engaged with the driven ring 71 and the switch handle 22 are prevented from swinging to disable the connection operation to the switch 21.

It is provided. When the plug 80 is not inserted, the outlet body 10 is detachably attached to the outlet lid 5 by a protective lid 8 connected to the outlet lid 5 by a chain, for example.
[0013]
The switch mechanism 20 is provided by being watertightly fixed to the switch opening 6, and the switch 21 arranged and fixed on the back (bottom) in the outlet main body 1 has a predetermined angle between the connection position and the cutting position. A switch handle 22 that is swung and stopped within a range is connected to a switch 21 that has a built-in swinging internal contact via a switch shaft 23 that penetrates the outlet lid 5 and is connected to the outlet lid 5. It has been arranged. As shown in FIGS. 1 and 5, the switch shaft 23 itself is fixed to the rear surface of the outlet lid 5 substantially in parallel with the outlet lid 5 by screwing or the like in consideration of ease of assembly and construction work. The upper part connected to the switch handle 22 and the lower part connected to the switch 21 are connected to each other via the coupling 26 arranged on the upper side. Yes. The swinging operation of the switch handle 22 is directly transmitted to the switch 21 through the coupling 26, and the swinging range is substantially the same as that of the internal contact. It should be noted that the coupling 26 is disposed on the upper portion on the switch handle 22 side so as to be engaged with the upper portion of the switch shaft 23 and the switch shaft is disposed on the lower portion on the switch 21 side. The lock-side coupling portion 26B meshed with the lower portion of the switch 23 is formed in a groove portion around the meshed portion so as to be swingable with respect to each other on the plane and meshed with the switch shaft 23 on the same axis. Is. Further, in the drawing, the switch handle 22 is surrounded by a protective wall 24 that protrudes integrally with the outlet lid 5 so as to prevent erroneous operation of the switch handle 22 from the outside. .
[0014]
Further, the switch mechanism 20 includes a quick input speed switch that instantaneously switches between the switch handle 22 that swings when the switch handle 22 is turned on at the connection position, and conversely when the switch handle 22 is turned off at the cutting position. Means 31 are incorporated. As shown in FIGS. 3 to 7, the quick-input / speed-off means 31 includes a drive cam 32 that is oscillated and rotated between the connection position and the cutting position following the oscillation of the switch handle 22, and the connection position and the cutting position. A lock cam 42 that is oscillated between positions and linked to the switch 21, a connection position stopper 51 that stops the lock cam 42 at the connection position, a cutting position stopper 56 that stops at the cutting position, and a drive cam 32. In addition, the cams 32 are connected to each other between the lock cams 42, and a torsional and elastic force is applied as the drive cam 32 swings. When the drive cam 32 reaches the connection position, the torsional and elastic force is released. Then, the lock cam 42 is displaced from the cutting position to the connection position, and conversely, when the drive cam 32 reaches the cutting position, the torsional elastic force is released and the lock cam 42 is disconnected from the connection position. Those comprising a torsion spring 61 is displaced to the position.
[0015]
The drive cam 32 is shown in the figure, and is formed in a substantially donut board shape fitted around the upper drive side coupling portion 26A of the coupling 26 of the switch shaft 23, and is connected to a connection position stopper 51 on the outer periphery. The Mt. Fuji-shaped projecting piece stopper pressing projection 34 is provided so as to project and immerse each of the cutting position stoppers 56 against the elastic force. The drive cam 32 itself meshes with the drive side coupling portion 26A. For example, the drive cam 32 is symmetrically formed near the inner peripheral edge of the drive cam 32 in the recess 27 formed symmetrically on the peripheral edge of the drive side coupling portion 26A. The projecting piece 33 cut and raised is locked. In this way, the swinging operation on the switch handle 22 causes the drive cam 32 to similarly swing and rotate on the plane via the drive side coupling portion 26A, the concave portion 27, and the protruding piece 33.
[0016]
The lock cam 42 is shown in the figure, and is formed in a substantially donut board shape that is swingably fitted around the lock-side coupling portion 26B of the coupling 26 of the switch shaft 23, and is connected to a connection position stopper 51 on the outer periphery. The connection position fixing groove 43 and the cutting position fixing groove 44 that are locked to the cutting position stoppers 56 are formed in a notch shape. The lock cam 42 itself meshes with the lock-side coupling portion 26B. For example, the lock cam 42 is symmetrically cut in the recess 28 formed symmetrically on the peripheral edge of the lock-side coupling portion 26B near the inner peripheral edge of the lock cam 41. The raised protrusion 47 is locked. By doing so, when the lock cam 42 itself is swung, the internal contact of the switch 21 is swung on the plane via the projecting piece 47, the recess 28, and the lock side coupling portion 26B. The outer peripheral edge between the connection position fixing groove 43 and the cutting position fixing groove 44 is a curved edge having such a curvature that the stoppers 51 and 56 are pressed and kept in an immersive state when the lock cam 42 swings. 46, and the curved edge 46 itself is larger than the arrangement angle between the connection position stopper 51 and the cutting position stopper 56, and has a length corresponding to, for example, about twice that angle. The drive cam 32 and the lock cam 42 are arranged so as to overlap each other so that the stopper pressing protrusion 34 is positioned at substantially the center position of the curved edge 46 when the 32 is stationary in the connected state or the disconnected state. (See FIGS. 1 and 5).
[0017]
As shown in the figure, the drive cam 32 and the lock cam 42 are arranged so that the drive cam 32 is coaxially on the upper side and the lock cam 42 is coaxially on the lower side, and the drive side coupling portion 26A and the lock side coupling portion 26B are arranged around the meshing portion. In the meantime, a perforated disk-like slide spacer 39 is interposed so that each slides and swings smoothly with respect to the other.
[0018]
The connection position stopper 51 and the cutting position stopper 56 are respectively provided in the switch flange 25 so as to be able to protrude and retract with respect to the switch flange 25 at positions corresponding to the connection position and the cutting position of the internal contact of the circuit in the switch 21. These stoppers 51 and 56 are formed with the same structure except for the positions where they are provided. That is, the grooved slide guide recesses 52 and 57 formed in the switch flange 25 are projected and urged by the elastic force of the coil springs 53 and 58 housed therein, and are also applied to the slide guide recesses 52 and 57. It is housed in such a manner that it is guided by an appropriate slide guide part that is provided.
[0019]
The torsion spring 61 is arranged so as to surround the drive side coupling portion 26A in the coupling 26, and one end thereof is constituted by a drive cam 32 and the other end is constituted by a coil spring engaged with the lock cam 42, respectively. For example, a locking end 62 that is bent and formed in a substantially U shape in each part is formed by cutting and raising the drive cam 32, and a slide guide hole 36 that is substantially arcuate in a plane that opens to the drive cam 32. And a spring engaging protrusion 45 formed by cutting and raising the lock cam 42 so as to protrude through the elastic cam, and is engaged with each other in a reduced twisting tendency. That is, the torsion spring 61 includes a spring engagement protrusion 45 of the lock cam 42 that does not initially swing even when the drive cam 32 swings, and a spring engagement that swings as the drive cam 32 starts swinging. The torsional elastic force is accumulated between the projecting pieces 35, and when the drive cam 32 reaches the predetermined position, the elastic force of the elastic member pulls the lock cam 42 so that the lock cam 42 is instantaneously forced. It is intended to swing and rotate (see FIGS. 6B and 7B).
[0020]
Further, when the circuit is connected to the quick-input / speed-off means 31, the drive cam 32 has its stopper pressing projection 34 pressed and retracted the cutting position stopper 56, and the lock cam 42 has its connection position fixing groove 43 connected. The protruding connection position stopper 51 located at the position stopper 51 is fitted into and locked in the connection position fixing groove 43 (see FIG. 3). On the other hand, when the circuit is in a disconnected state, the drive cam 32 has its stopper pressing protrusion 34 pressed and inserted the connection position stopper 51, and the lock cam 42 has its cutting position fixing groove 44 positioned at the cutting position stopper 56. The protruding cutting position stopper 56 is fitted and locked in the cutting position fixing groove 44 (see FIG. 4).
[0021]
When the switch handle 22 is swung so as to be displaced to the connection position so as to connect an electric circuit in the quick turn-off means 31 configured as described above (clockwise in FIG. 2). 6 (A), from the state where the circuit is disconnected (see FIG. 7 (C)), the drive cam 32 swings and its stopper pressing projection 34 is connected to the position of the connection position stopper 51. At the same time, the spring engagement protrusions 35 are separated from the spring engagement protrusions 45 of the lock cam 42 to impart a torsional elastic force to the torsion spring 61 (see FIG. 6B). In the meantime, the lock cam 42 does not swing, and the cutting position stopper 56 is engaged with the cutting position fixing groove 44 to keep the circuit cut. Then, when the stopper pressing protrusion 34 of the drive cam 32 in which the swing operation is continued rotates and presses the cutting position stopper 56 so as to be immersed, the cutting position fixing groove that has been locked by the cutting position stopper 56 so far. The lock cam 42 is released and the lock cam 42 is swung clockwise by the elastic force of the torsion spring 61. Then, the connection position fixing groove 43 of the lock cam 42 reaches the position of the connection position stopper 51, and the connection position stopper 51 protruding elastically fits into the connection position fixing groove 43 to stop the lock cam 42 (FIG. 6). (See (C)), the rocking of the lock cam 42 itself at this time rocks the internal contact of the switch 21 to bring it into a connected state.
[0022]
On the contrary, when the switch handle 22 is swung so as to be displaced to the cutting position to cut the electric circuit (swing in the counterclockwise direction in FIG. 2), as shown in FIG. From the circuit connection position (see FIG. 6C), the drive cam 32 swings and its stopper pressing projection 34 moves away from the cutting position stopper 56 position. The torsion spring 61 is imparted with a torsional elastic force by separating from the spring engaging protrusion 45 (see FIG. 7B). In the meantime, the lock cam 42 does not swing, and the connection position stopper 51 is engaged in the connection position fixing groove 43 to maintain the circuit connection state. Then, when the stopper pressing protrusion 34 of the drive cam 32 in which the swinging operation is continued rotates and presses the connection position stopper 51 so as to be immersed, the connection position fixing groove that the connection position stopper 51 has been locked until then. The locked state of the locking cam 42 is released by the elastic force of the torsion spring 61 and the locking cam 42 is swung counterclockwise. Then, the cutting position fixing groove 44 of the lock cam 42 reaches the position of the cutting position stopper 56, and the cutting position stopper 56 protruding elastically fits into the cutting position fixing groove 44 to stop the lock cam 42 (FIG. 7). (See (C)), the rocking of the lock cam 42 itself at this time rocks the internal contact of the switch 21 to bring it into a disconnected state.
[0023]
Further, the interlock mechanism 70 allows the plug 50 to be inserted / removed only when the switch mechanism 20 is in a circuit disconnected state, and conversely, the plug 80 cannot be inserted / removed when the circuit connected state is present. Only when the plug 80 is inserted and inserted, the switch mechanism 20 can be disconnected and the switch handle 22 can be swung for connection. Therefore, as shown in FIGS. 3, 4, 8, and 9, the interlock mechanism 70 is disposed around the outlet body 10 so as to be swingable on a plane. A driven ring 71 having a locking portion 73 that can be locked to a guide projection 85 of a plug 80 that is swung with the swing of the drive cam 32 and is inserted into the outlet body 10 and inserted into the plug 80. It is provided with a locking means 76 that slides to release the locking with the driven ring 71 and locks with the driven ring 71 when the plug 80 is removed.
[0024]
The driven ring 71 is formed in a donut plate shape that surrounds the outlet body 10, and can be oscillated and rotated by a support plate 75 that is fixed to the rear surface of the outlet lid 5, for example, in a band plate shape and arranged in a pair. It is supported. An engaging projection 72 that engages with the drive cam 32 is provided at the peripheral portion on the switch mechanism 20 side, and the guide groove 15 of the guide cylinder portion 12 is inserted so that the plug 80 is inserted into the outlet body 10 at a specific position. On the upper surface of the guide projection 85 to be fitted in, there is, for example, an inverted L-shaped locking portion 73 that is locked by the swinging rotation of the driven ring 71 itself, and the angle of the swinging range with respect to the locking portion 73 A lock groove 74 that is locked by the lock means 76 is provided in a notch shape on the lower surface. The engaging protrusion 72 protrudes in a cylindrical shape on the lower surface of the driven ring 71 itself. For example, the engaging protrusion 72 protrudes in a bifurcated manner on the outer side of the drive cam 32 in the quick entry / speed-off means 31 with a predetermined angle. The driven ring 71 is engaged with the rocking linkage portion 38 via the rocking linkage portion 38 and the engagement projection 72 that are engaged with each other as the drive cam 32 is swung. It swings and rotates (see FIGS. 3 and 4).
[0025]
The locking means 76 is disposed at a position corresponding to the position of the guide projection 85 of the plug 80 inserted into the outlet body 10 and is pressed by, for example, the opening end of the plug 80 inserted into the lock chamber 77 formed in the support plate 75. As an example, a lock key 78 that is detachably engaged with the driven ring 71 in a state in which the plug 80 is protruded toward the outlet lid 5 that is the insertion side of the plug 80 is slidably inserted through the slide guide. Is. As shown in FIG. 9, the upper portion of the lock chamber 77 is opened, and is opened by a lock groove 74 which is closed or slid by a driven ring 71 which is swung and rotated as the drive cam 32 is swung. On the other hand, the lock key 78 itself has a substantially crank shape as viewed from the side as shown in the figure, and protrudes toward the outlet lid 5 by the elastic force of the coil spring 79 housed inside. When the plug 80 is not inserted, the driven ring 71 has its lock groove 74 at the position of the lock chamber 77 and the lock key 78 is engaged with the lock groove 74, so that the driven ring 71 itself swings and rotates. (See the enlarged sectional view taken along the line B-B shown in FIG. 4). As a result, as shown in FIG. 4, the engaging protrusion 72 and the oscillating connecting portion 38 that are engaged with each other are connected. Accordingly, the drive cam 32 and the switch handle 22 in the switch mechanism 20 are also prevented from swinging and rotating.
[0026]
Here, when the plug 80 is inserted into the outlet body 10 and the electrode pin 83 and the grounding electrode pin 84 are inserted into the electrode contactor 13 and the grounding electrode contactor 14 of the contactor mechanism 11, respectively, as shown in FIG.
