[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Reference Figure 1-9 An embodiment of the present invention provides an anti-misplugging structure for a surge protector, comprising a base 1 and a plurality of main bodies 2 detachably connected to the base 1, wherein the base 1 is provided with wiring holes 3 and a blocking mechanism, wherein the wiring holes 3 are provided with a plurality of holes for connecting a neutral wire, a live wire or a ground wire; the blocking mechanism has a first state for blocking the plurality of wiring holes 3 and a second state for opening the plurality of wiring holes 3, and when the plurality of main bodies 2 are installed on the base 1, the blocking mechanism switches to the second state.

[0034] Specifically, an anti-misplugging structure is generally provided between the base 1 and the multiple main bodies 2 of the surge protector, such as a mutually compatible connection structure between the base 1 and the main body 2, so that the base 1 and the main body 2 of the same model can be connected together, and for the base 1 and the main body 2 of different models, the connection structures of the two are not compatible and cannot be plugged together, thus achieving the purpose of anti-misplugging. The above are all in the prior art and are not repeated here. A plurality of main bodies 2 are generally provided on the base 1 of the surge protector. In actual use, the user may reduce the number of main bodies 2 used, resulting in a lack of main bodies 2 on the base 1. At this time, directly inserting the neutral wire, the live wire or the ground wire into the wiring hole 3 of the base 1 will cause the device to operate in an incomplete state, which will increase the probability of damage to the device. In order to avoid this as much as possible, In order to prevent the situation in which a wire is inserted into the wiring hole 3 under the wrong condition, an embodiment of the present invention provides an anti-wrong insertion structure. The innovation lies in that a blocking mechanism is arranged on the base 1, and the blocking mechanism can be a combination of an electric push rod and a baffle, so that the baffle is controlled by the electric push rod to block or open the multiple wiring holes 3; multiple position sensors can be arranged on the base 1, and the multiple position sensors correspond to the multiple main bodies 2 one by one. When the multiple position sensors all detect that the corresponding main bodies 2 are installed on the base 1, the blocking mechanism switches to the second state to open the multiple wiring holes 3. On the contrary, when one or more position sensors do not detect the existence of the main body 2, the blocking mechanism maintains the first state to block the wiring hole 3, so as to avoid the wire being inserted into the corresponding wiring hole 3 under the wrong condition as much as possible.

[0035] An embodiment of the present invention provides an anti-misinsertion structure for a surge protector. A plurality of wiring holes 3 can be blocked through a first state of a blocking mechanism. At this time, wires cannot be connected to the base 1. When in use, a plurality of main bodies 2 are installed on the base 1 to form a complete surge protector. At this time, the blocking mechanism switches to a second state to open the plurality of wiring holes 3, so that the neutral wire, the live wire or the ground wire can be normally inserted into the wiring hole 3 for connection. In this way, the neutral wire, the live wire or the ground wire can be prevented from being inserted into the base 1 when the surge protector is incomplete, thereby maximizing the safety of the device.

[0036] In another embodiment provided by the present invention, further, a plug connector 4 is fixed on the main body 2, and a plug slot 5 is configured on the base 1. Specifically, the base 1 is configured as a U-shape as a whole, and a plurality of plug slots 5 are configured thereon at equal intervals. The main body 2 can be plugged into the corresponding plug slot 5 through the plug connector 4. An elastic buckle structure can be provided between the plug connector 4 and the plug slot 5, or the plug connector 4 and the plug slot 5 can be connected by interference fit. The plug connector 4 and the plug slot 5 of different models can be configured to have different cross-sectional shapes, so that different models of main bodies 2 can be prevented from being plugged into the same base 1 by mistake, thereby realizing the function of preventing the main body 2 from being plugged in by mistake.

[0037] In another embodiment provided by the present invention, further, the blocking mechanism includes a slide plate 6 slidably connected to the base 1, a plurality of blocking plates 7 are fixed on the slide plate 6, and a first elastic member 8 is provided between the base 1 and the connecting plate 15. Specifically, the blocking plate 7 is constructed in an L-shape, and its two ends are respectively attached to two adjacent outer walls (top wall and side wall) of the base 1, and a slide groove 9 is constructed on the base 1 along its width direction. The slide plate 6 is slidably connected in the slide groove 9, so that the slide plate 6 and the blocking plate 7 slide along the base 1 through the slide groove 9, thereby driving the blocking plate 7 to block the wiring hole 3 or release the blocking of the wiring hole 3 by the blocking plate 7; the first elastic member 8 can select a spring or elastic telescopic rod structure in the prior art, one end of the first elastic member 8 is fixed to the outer wall of the base 1, and the other end is fixed to the blocking plate 7, the first elastic member 8 is in a stretched state to force the slide plate 6 to slide to one end of the slide slot 9, thereby driving the multiple blocking plates 7 to block the corresponding wiring holes 3, which is the first state of the blocking mechanism. When the position sensor detects that the multiple main bodies 2 are installed on the main body 2, the user manually moves the slide plate 6 to move the slide plate 6 to the other end of the slide slot 9. At this time, the multiple blocking plates 7 release the blocking of the multiple wiring holes 3, so that the neutral wire, the live wire or the ground wire can be normally inserted into the wiring hole 3 for connection, which is the second state of the blocking mechanism.

[0038] Preferably, a plurality of bolt holes 10 are constructed on the base 1 , and the plurality of bolt holes 10 correspond to the plurality of wiring holes 3 . Specifically, the bolt hole 10 is connected to the wiring hole 3, an elastic sheet 11 is provided in the wiring hole 3, a bolt 12 is threadedly connected to the bolt hole 10, and the bottom end of the bolt 12 contacts the elastic sheet 11. When the bolt 12 is tightened, the bolt 12 contacts the elastic sheet 11 to squeeze the wire in the wiring hole 3 through the elastic sheet 11, so that the wire can be stably connected to the corresponding wiring hole 3; when the bolt 12 is loosened, the elastic sheet 11 releases the squeezing of the wire, so that the wire can be moved out of the corresponding wiring hole 3, so that the wire can be removed from the wiring hole 3; the bolt hole 10 and the wiring hole 3 are respectively located on two adjacent side walls (top wall and side wall) of the base 1, and the bolt hole 10 is directly above the corresponding wiring hole 3, and the two ends of the L-shaped blocking plate 7 correspond to the bolt hole 10 and the wiring hole 3 respectively, so that when the blocking plate 7 blocks the wiring hole 3, the bolt hole 10 can be blocked at the same time, thereby achieving double blocking and avoiding connecting the wire at the wrong time as much as possible.

[0039] Furthermore, the base 1 is provided with a limiting groove 13, and the main body 2 is provided with a limiting block 14. Specifically, the base 1 is provided with a plurality of limiting grooves 13 at equal intervals, and the number of limiting grooves 13, limiting blocks 14, plug-in slots 5 and plug-in blocks corresponds to one another; when the main body 2 is inserted into the corresponding position of the base 1, the plug connector 4 on the main body 2 will be inserted into the corresponding plug-in slot 5, and at the same time, the limiting block 14 on the main body 2 will be embedded in the corresponding limiting groove 13, and an interference fit can be adopted between the limiting groove 13 and the limiting block 14, so that the position of the main body 2 can be further limited, and the main body 2 can be prevented from being separated from the base 1 as much as possible.

[0040] In another embodiment provided by the present invention, further, a connecting plate 15 is fixed on the blocking plate 7, and a plurality of locking mechanisms for locking the connecting plate 15 are provided on the base 1. Specifically, in the above embodiment, the slide plate 6 and the blocking plate 7 are only limited by the first elastic member 8 when sliding along the slide groove 9. Obviously, this limiting method is not stable enough. Therefore, a plurality of locking mechanisms are provided, and the connecting plate 15 is fixed at the same end of the plurality of blocking plates 7. The locking mechanism is used to lock the relative position of the base 1 and the connecting plate 15; a group of locking mechanisms corresponds to a main body 2, and the locking mechanism can select an electric locking structure. When a main body 2 is installed on the base 1, the corresponding position sensor sends an electric signal to the electric locking structure to release the corresponding locking mechanism from locking the connecting plate 15, until all the main bodies 2 are installed on the base 1, and all the locking mechanisms are unlocked, so that the connecting plate 15, the blocking plate 7 and the slide plate 6 can slide along the slide groove 9, thereby blocking or releasing the blocking of the wiring hole 3 and the bolt hole 10.

[0041] As an alternative to the above-mentioned position sensor and electric locking structure, preferably, the locking mechanism includes a locking groove 16 constructed on the connecting plate 15 and a locking block 17 slidably connected to the base 1, and a second elastic member 18 is provided between the base 1 and the locking block 17. The locking block 17 is constructed in an L shape. Specifically, a connecting groove 19 connected to the limiting groove 13 is constructed on the base 1, and the locking block 17 is slidably connected in the limiting groove 13 and the connecting groove 19 of the base 1. When the limiting block 14 enters the limiting groove 13, it will abut against the locking block 17. At this time, one end of the locking block 17 is located below the limiting block 14, and the top wall of the other end is flush with the top wall of the limiting block 14 (such as Figure 6As shown); the second elastic member 18 is provided with multiple groups and is respectively arranged in multiple connecting grooves 19. The second elastic member 18 can select a spring or elastic telescopic rod structure in the prior art. One end of the second elastic member 18 is fixed on the inner wall of the connecting groove 19, and the other end is fixed on the locking block 17. The second elastic member 18 is in a compressed state to force the locking block 17 to extend out of the limiting groove 13 (that is, protrude from the top wall of the base 1); before the main body 2 is installed, the blocking plate 7 blocks the wiring hole 3 under the elastic force of the first elastic member 8. At this time, the position of the locking groove 16 corresponds to the position of the locking block 17, so that the locking block 17 can extend out of the limiting groove 13 and be inserted into the corresponding locking groove 16 under the action of the second elastic member 18, so that the position of the connecting plate 15, the blocking plate 7 and the sliding plate 6 can be limited (as shown in the figure). Figure 7 As shown), try to avoid the slide plate 6 from moving under the action of external force; when the main body 2 is installed to the corresponding position of the base 1, the limiting block 14 on the main body 2 is embedded in the corresponding limiting groove 13, and the limiting block 14 will squeeze the locking block 17 in the limiting groove 13 to force the locking block 17 to squeeze the second elastic member 18 (in the process, the locking block 17 is gradually retracted from the locking groove 16 into the limiting groove 13), until the main body 2 is completely installed on the base 1, the limiting block 14 is completely embedded in the limiting groove 13, at this time the locking block 17 is completely retracted into the limiting groove 13, that is, the locking block 17 is completely moved out of the corresponding locking groove 16. The advantage of such a configuration is that, when the main body 2 is not installed on the base 1, the connecting plate 15 is locked by multiple sets of locking mechanisms and cannot slide on the base 1; when a main body 2 is installed on the base 1, the corresponding locking mechanism releases the lock on the connecting plate 15 (that is, the corresponding locking block 17 is moved out of the corresponding locking groove 16), and at this time the connecting plate 15 is still locked by other locking mechanisms and cannot slide on the base 1; until all the main bodies 2 on the base 1 are installed, all the locking mechanisms correspondingly release the lock on the connecting plate 15, so that the connecting plate 15 can slide along the slide groove 9 to drive the blocking plate 7 to release the blockage of the wiring hole 3. In this way, the position sensor and the electric locking structure in the above-mentioned embodiment can be replaced. When the main body 2 is not installed on the base 1, the blocking plate 7 passively blocks the wiring hole 3 under the action of the first elastic member 8, and the locking block 17 passively locks the connecting plate 15 under the action of the second elastic member 18. After the main body 2 on the base 1 is fully installed, all the locking blocks 17 are passively received in the corresponding limiting grooves 13 to release the restriction of the locking blocks 17 on the connecting plate 15, so that the connecting plate 15 can drive the blocking plate 7 to move away from the wiring hole 3 for wiring operations.

[0042] Preferably, the connecting plate 15 extends above the limiting groove 13 . Specifically, the locking groove 16 is constructed to be open on one side close to the main body 2. When the multiple locking mechanisms lock the connecting plate 15, the locking groove 16, the limiting groove 13 and the connecting groove 19 correspond to each other. At this time, the limiting block 14 on the main body 2 can enter the limiting groove 13 through the opening of the locking groove 16 to squeeze the locking block 17 and release the restriction of the locking block 17 on the locking groove 16; when the multiple locking mechanisms are unlocked, the user manually moves the position of the blocking plate 7 to remove the blocking plate 7 from the wiring hole 3. At this time, the neutral wire, the live wire or the grounding wire can be inserted into the corresponding wiring hole 3, and then the blocking plate 7 is loosened to reset the blocking plate 7 under the action of the first elastic member 8, which will cause the blocking plate 7 to resist the wires in the wiring hole 3, thereby preliminarily restricting the wires in the wiring hole 3, making it convenient for subsequent users to directly tighten the bolts 12 from the bolt holes 10 to stably connect the wires (when the blocking plate 7 is removed from the position of the wiring hole 3, the blocking of the bolt holes 10 is simultaneously released). After the wire connection is completed, the blocking plate 7 cannot be reset to the position for blocking the wiring hole 3 due to the resistance of the wire. At the same time, the position of the locking groove 16 is misaligned with the position of the locking block 17. The locking block 17 cannot be inserted into the corresponding locking groove 16 under the action of the second elastic member 18, and the limiting groove 13 and the connecting groove 19 are both blocked by the connecting plate 15. The advantage of such a setting is that when the blocking plate 7 blocks the wiring hole 3 and the bolt hole 10, the main body 2 can be installed on the base 1 or removed from the base 1 at will; when the main body 2 is fully installed on the base 1, the blocking plate 7 can be moved away from the position of blocking the wiring hole 3 to perform wiring operations through the wiring hole 3; when the wiring hole 3 is being wired, the blocking plate 7 cannot be reset due to the resistance of the wire, so that the locking groove 16 is misaligned with the limiting groove 13 (the locking groove 16 is also misaligned with the locking block 17), so that the connecting plate 15 can be connected to the limiting block 14 in the limiting groove 13 and the locking block 17 in the connecting groove 19. The block 17 is blocked, so that the relative position of the base 1 and the main body 2 can be limited, and the main body 2 can be avoided from being removed from the base 1 during the use of the device; when the device needs to be replaced, the wires in the wiring hole 3 are taken out, so that the blocking plate 7 can be reset to the position for blocking the wiring hole 3, so that the locking block 17 can enter the corresponding locking groove 16 under the action of the second elastic member 18 to lock the connecting plate 15 again. At the same time, the limiting block 14 on the main body 2 can also be taken out through the opening of the locking groove 16, thereby completing the replacement of the device or the replacement of the main body 2.

[0043] In another embodiment provided by the present invention, a movable rod 20 is rotatably connected to the blocking plate 7. Specifically, a movable groove 21 is constructed on the base 1, and a movable column 22 is constructed at one end of the movable rod 20, and the movable column 22 is slidably connected in the movable groove 21. Figure 8As shown, when the blocking plate 7 blocks the corresponding wiring hole 3, the movable rod 20 is at a certain angle to the blocking plate 7, so that the blocking degree of the wiring hole 3 can be improved as much as possible without changing the width of the blocking plate 7. When the blocking plate 7 slides along the slide groove 9 with the slide plate 6 to release the blocking of the wiring hole 3 (as shown in FIG. Figure 8 As shown in the figure, the blocking plate 7 slides to the right), the movable rod 20 and the hinge point of the blocking plate 7 move synchronously, which will force the movable column 22 at one end of the movable rod 20 to slide upward along the movable groove 21 (the movable column 22 rotates a certain angle while sliding in the movable groove 21), until the blocking plate 7 releases the blockage of the wiring hole 3, the blocking plate 7 and the movable rod 20 are in a nearly parallel state, so as to minimize the influence of both on the wiring operation in the wiring hole 3; correspondingly, when the blocking plate 7 blocks the wiring hole 3 again, the movable rod 20 will rotate around the blocking plate 7 again to cooperate with the blocking plate 7 to block the wiring hole 3.

[0044] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
