[0038] The following discloses a variety of different implementation methods or embodiments of the subject technical solution. To simplify the disclosure, specific examples of each element and arrangement are described below. Of course, these are only examples and are not intended to limit the scope of protection of the present invention. For example, the first feature subsequently recorded in the specification is formed above or on the second feature, which may include an implementation method in which the first and second features are formed by direct connection, and may also include an implementation method in which an additional feature is formed between the first and second features, so that the first and second features may not be directly connected. In addition, the figure marks and / or letters may be repeated in different examples in these disclosures. This repetition is for simplicity and clarity, and does not itself represent the relationship between the various implementation methods and / or structures to be discussed. Further, when the first element is described in a manner connected or combined with the second element, the description includes an implementation method in which the first and second elements are directly connected or combined with each other, and also includes the use of one or more other intervening elements to indirectly connect or combine the first and second elements.

[0039] Figure 1 and Figure 4 FIG. 1 shows an electrical connection system, wherein a plug 1 and a socket 2 are in a coupled state. Figure 2 and Figure 3 In the embodiment, the plug 1 and the socket 2 are in a disconnected state. The power control switch 3 is a knob that controls the on and off of the power supply device 4. The power supply device 4 supplies power to the socket 2 through the power line 41. Figure 2 As shown, the socket 2 has a plurality of socket parts 21, which have built-in electrical contacts. Correspondingly, the plug 1 has a plurality of plug pins 110, which are plugged and matched with the socket parts 21. When the power supply device 4 is switched to the on state by the power control switch 3, current flows between the plug pins 110 and the electrical contacts between the socket parts 21. In some cases, the current flowing between the plug 1 and the socket 2 is relatively large. When the plug 1 and the socket 2 are powered, it is a dangerous operation to unplug the plug 1. Therefore, it is not expected that the plug 1 cannot be unplugged once it is combined with the socket 2 and powered, unless the powered state is released. On the other hand, when the plug 1 is not inserted into the socket 2, it is not expected that the plug 2 is in a powered state. The mechanical interlock device described later can achieve the above-mentioned purpose.

[0040] Figure 5 The mechanical interlocking device is shown in Figures 1 to 4 Application in the electrical connection system shown in FIG. Figure 6 The mechanical interlock is shown separately. Figure 6 It can be understood as Figure 5 Magnified view of the mechanical interlock.

[0041] like Figure 6As shown, the mechanical interlocking device includes a first component 51 and a planar motion mechanism. The planar motion mechanism includes a prime mover 52, a second component 53 and an output component 54.

[0042] Figure 7 and Figure 8 shows the first state of the mechanical interlocking device, Fig. 9 and Fig.10 The second state of the mechanical interlocking device is shown. Figure 8 and Fig.10 The prime mover 52, the second member 53 and the output member 54 can also be seen.

[0043] Combined with Figure 6 , Figure 8 and Fig.10 , the first member 51 is arranged on the insertion path of the plug 1 in the socket 2, and is arranged to slide along the first direction Z. The insertion path is the moving path of the plug 1 in the socket 2, or the position that the plug 1 can reach or pass. The first direction Z is usually the same as the direction of the plug 1 moving forward and backward in the socket 2. In the embodiment shown in the figure, the first member 51 is a push rod, and the first direction Z is usually the same as the extension direction of the push rod. The prime mover 52 is Figure 8 In the first state shown, it is releasably locked with the first component 51 . Figure 8 and Fig.10 An embodiment of the lock is shown, the first component 51 has a push rod first end 511 and a push rod second end 512, a push rod buckle 513 is provided at the push rod second end 512, and the push rod buckle 513 has a push rod tooth 514 and a push rod groove 515. Correspondingly, the prime mover 52 is an interlocking block, including an interlocking buckle 521, and the interlocking buckle 521 also has an interlocking tooth 522 and an interlocking groove 523. Figure 8 As shown, the push rod teeth 514 and the push rod grooves 515, and the interlocking teeth 522 and the interlocking grooves 523 are in a state of being engaged with each other, that is, in a state of being interlaced.

[0044] The second member 53 is Figure 8 and Fig.10 Located in different positions, it can be Figure 8 Slide up to the position shown Fig.10 shown, or from Fig.10 Slide down to the position shown Figure 8 The sliding direction of the second member 53 is also the first direction Z, and is spaced apart from the first member 51 and is parallel or substantially parallel to the first member 51. In the embodiment shown in the figure, the second member 53 is an elongated slider having a slider first end 531 and a slider second end 532.

[0045] The output member 54 is Figure 8 and Fig.10Located in different locations, Figure 8 In the case of plug 1, the insertion path is left, and in the case of Fig.10 In the embodiment, the output member 54 enters the insertion path of the plug 1 and abuts against the plug 1, so that the plug 1 cannot be pulled out.

[0046] The output member 54 may be Figure 8 The status and Fig. 9 Switches between the states shown. Fig.10 It can also be noted that, in addition to the output member 54 being locked against the plug 2, the driving member 52 and the first member 51 are in a disengaged state, that is, at this time, the planar motion mechanism is in an active state. In the first state, the driving member 52 is locked by the first member 51, and the output member 54 leaves the insertion path, so the plug 1 can also be inserted into the socket 2, but the planar motion mechanism is locked by the first member and cannot move.

[0047] Combination Figure 8 and Fig.10 It can also be understood that the mechanical interlocking device consists of Figure 8 The first state shown switches to Fig.10 In the second state shown, the first member 51 moves downward first, so that the first member 51 and the driving member 52 are unlocked. Then the parallel motion mechanism can be activated, and the driving member 52 is driven by the power control switch 3, the driving member 52 is linked to the second member 53, and the second member 53 is linked to the output member 54, and the second member 53 moves upward. Fig.10 The second state shown switches to Figure 8 In the first state shown, the driving member 52 is first driven by an external force, such as the power control switch 3, and then Fig.10 Move to the position shown Figure 8 In the position shown, the driving member 52 drives the second member 53 to move downward, and the second member 53 drives the output member 54 to swing leftward and leave the insertion path of the plug 1. Then the first member 51 moves upward again and locks with the driving member 52. Therefore, during the switching process, the movement direction of the second member 53 is set opposite to that of the first member 51.

[0048] from Figure 6 , Figure 8 and Fig.10 It can also be seen that the mechanical interlocking device requires little space and can be set by adding a space on one side of the first member 51. The mechanical interlocking device utilizes the second member 53 that moves in the opposite direction to the first member 51 and slides parallel or substantially parallel to the first member 51 to output the movement of the locking plug 1 to the plug 1. Compared with the lever mechanism, it does not require space for the lever to swing, so it requires less space.

[0049] The linkage mode of each part in the planar motion mechanism is Figure 8 and Fig.10 There is an example, for example, the second member 53 and the driving member 52 are connected by a connecting rod 55. The connecting rod 55 includes a connecting rod first end 551 and a connecting rod second end 552, and is rotatably arranged in the socket 2 around the axis between the connecting rod first end 551 and the connecting rod second end 552, for example, by installing a pivot 553. Figure 6 As shown, the first end 551 of the connecting rod has an elongated hole 5511, and the second end 552 of the connecting rod has an elongated hole 5521. The elongated hole 5511 of the first end 551 of the connecting rod is slidably matched with the pin 524 installed on the prime mover 52, and the pin 524 can also rotate in the elongated hole 5511, thereby forming a sliding hinge structure. The elongated hole 5521 of the second end 552 of the connecting rod is matched with the pin 533 installed on the first end 531 of the slider of the second member 53, and the pin 533 can slide and rotate in the elongated hole 5521, thereby forming a sliding hinge structure. The prime mover 52 slides in the horizontal direction, that is, it slides in a direction roughly perpendicular to the direction Z. The length of each elongated hole is set according to the principle of mechanism, as long as it can satisfy the conversion of the sliding of the prime mover 52 into the sliding of the second member 53. The elongated holes 5521 and 5511 are shown in the figure as extending in a straight line in the length direction, but are not limited to this. According to the specific layout space, the length direction of the elongated holes can also be curved and extended. In addition, the positions of the elongated holes and the shafts of the aforementioned sliding hinge structure can usually be interchanged, and are not limited to the manner shown in the figure. It can also be understood from the above description that the linkage between the prime mover 52 and the second member 53 is to convert the sliding of the prime mover 52 into the sliding of the second member 53. Therefore, the linkage method is not limited to linkage through the connecting rod 55, but can also be other orthogonal transmission mechanisms or mechanisms similar to orthogonal transmission mechanisms. The linkage through the connecting rod 55 has the characteristics of simple structure, good action stability, and smooth mechanism.

[0050] like Figure 6 As shown, the upper end of the second member 53, i.e., the second end 532 of the slider, has a middle groove, or has two side walls, which clamp one end of the output member 54. The output member 54 is rotatable in the socket 1 by installing a pivot 543. Figure 8 and Fig.10 As shown, the left end of the output member 54 has an elongated hole 541, and a pin 5321 is installed at the upper end 532 of the second member 53. The cooperation between the pin 5321 and the elongated hole 541 allows them to slide against each other and also allows the pin 5321 to rotate, thereby forming a sliding hinge structure. The linkage arrangement of the second member 53 and the output member 54 allows the second member 53 to slide and the output member 54 to rotate, so the elongated hole 541 can have changes in size and shape according to the specific spatial arrangement. Fig.10As shown, the output member 54 acts as a latch, buckling against the plug 1, so that the plug 1 cannot be pulled out. Specifically, one side of the output member 54 has an inclined surface 542, and the side of the plug 1 has another inclined surface 100. The output member 54 rotates to make the two inclined surfaces 542 and 100 fit together. The buckling effect can be enhanced through surface-to-surface contact. It can be seen that the output member 54, as an output member of the planar motion mechanism, enters or leaves the insertion path of the plug 1, thereby locking or unlocking the plug 1.

[0051] The cooperation between the elongated hole 541 and the pin 5321 also has a self-locking function. Fig.10 Before the second state shown, the elongated hole 541 and the pin 5321 also have an intermediate state, that is, the intermediate state is between the first state and the second state, and the switching between the first state and the second state needs to pass through the intermediate state. Fig.11 and Fig.12 As shown, the second member 53 has pushed the output member 54 to the insertion path of the plug 1 through the elongated hole 541 and the pin shaft 5321. At this time, if the upward sliding of the second member 53 stops, the force trying to pull out the plug 1 will produce a reverse movement or a tendency of reverse movement, so that the force is transmitted to the output member 54, the second member 53, the prime mover 52, and the power control switch 3 described later. In order to prevent reverse movement, a variety of prevention measures can be taken, such as the rotation of the power control switch 3 itself needs to be unlocked, or a movable pin is used to cooperate with the prime mover 52, and another example is that the elongated hole 541 has an extension section 5411, and the extension section 5411 allows the pin 5321 to slide further upward, that is, after the second member 53 pushes the output member 54 to the insertion path of the plug 1, the extension section 5411 allows the second member 53 or the pin 5321 to slide further upward. The sliding at this time has nothing to do with pushing the output member 54, that is, the linkage between the two is disconnected, or the output member 54 will not rotate further, and the extension direction of the extension section 5411 is consistent with the sliding direction of the second member 53. Due to the further sliding provided by the extension section 5411, the mechanical interlocking device is Fig.11 and Fig.12 The intermediate state enters Fig. 9 and Fig.10 In the second state shown, since the further sliding of the pin 5321 provided by the extension section 5411 is independent of the rotation of the output member 54, the rotation of the output member 54 cannot reversely drive the pin 5321 or the second member 53, so that the mechanical interlocking device is self-locking, and the reverse movement generated by the force attempting to pull out the plug 1 is thus cut off or prevented. Fig.10 As shown, the upper end of the extension section 5411 constitutes a stop point for the pin shaft 5321 to slide upward, thereby fixing the second component 53 and preventing it from sliding further.

[0052] like Figure 8 and Fig.10 As shown, the first member 51 is provided with a return spring 519, and the return spring 519 is used to force the first member 51 to move to a position where it is locked with the prime mover 52. For example, after the first member 51 is pushed downward by the plug 1, the return spring 519 generates a force to push the first member 51 upward, so that the first member 51 tends to move upward. Once the plug 1 is pulled out, the first member 51 moves upward and resets. Since the plug 1 is locked by the output member 54, the plug 1 can only be pulled out after the output member 54 leaves the insertion path of the plug 1. In other words, the prime mover 52 is driven to Figure 8 The plug 1 can be pulled out only after it is in the position shown. Once the plug 1 is pulled out, the first component 51 is pushed upward by the spring force of the return spring 519 , so that the first component 51 locks the prime mover 52 .

[0053] like Figure 6 , Figure 8 and Fig.10 As shown, the prime mover 52 is slidably arranged along another direction perpendicular to (including the case of being substantially perpendicular to) the direction Z. As described later, the driving force on the prime mover 52, that is, the force generated by the power control switch 3, is consistent with the sliding direction of the prime mover 52, so it is easy to drive the prime mover 52.

[0054] Back to Figures 1 to 4 The power control switch 3 is arranged to be linked with the prime mover 52. The mechanical interlocking device is arranged in the first state when the plug 1 is separated from the socket 2, that is, Figure 8 When the plug 1 is inserted into the socket 2, the first member 51 is released from the prime mover 52 in response to the drive of the plug 1, and the prime mover 52 drives the aforementioned planar motion mechanism in response to the power control switch 3 being switched to the on state (so that the power supply device 4 is turned on), thereby switching the mechanical interlocking device to the second state.

[0055] One of the linkage modes between the power control switch 3 and the prime mover 52 is to use a crank-connecting rod slider mechanism. Figures 1 to 5 As shown, the power control switch 3 is a knob, which includes a knob rod 32, on which there is a disk 33, the disk 33 is hinged to the left end of a connecting rod 34, the right end of the connecting rod 34 is connected to the left end of a slide rod 36 through a hinge shaft 35, the slide rod 36 is constrained by a guide hole 370 on a guide sheet 37, and the right end of the slide rod 36 is hinged to the prime mover 52 and can only move.

[0056] Back to Fig.10The side surface of the plug 1 is provided with a protruding plug convex portion 11, and the plug convex portion 11 has a front side surface 116 and a rear side surface along the insertion direction of the plug 1, the rear side surface is the aforementioned inclined surface 100, the front side surface 116 is against the upper end of the first member 51, and the rear side surface is abutted by the output member 54. In this way, the first member 51 can smoothly switch between locking the aforementioned planar motion mechanism and the planar motion mechanism locking the plug.

[0057] like Figures 1 to 6 As shown, the electrical connection system further includes a travel switch 6, which is configured to be triggered by a first member 51. The travel switch 6 is used to control the indicating device to indicate whether the plug is inserted in place, and the travel switch 6 outputs a signal through a signal line 61. When the plug 1 is inserted into the socket 2, the plug protrusion 11 on the side of the plug 1 will push the first member 51 to move downward, and after the first member 51 is disengaged from the prime mover 52, it will push against the travel switch 6, thereby triggering the travel switch 6, which can assist in judging whether the plug 1 is inserted in place in the socket 2.

[0058] Although the present invention is disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art may make possible changes and modifications without departing from the spirit and scope of the present invention. Therefore, any modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall fall within the protection scope defined by the claims of the present invention.
