In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0050] Reference Figures 1 to 6 As shown, this embodiment provides an interlocking mechanism applied to a contactor.

[0051] Specifically, the contactor includes a contactor body 310 and a contact support 320 arranged on the contactor body 310, the contact support 320 is provided with a limiting surface 321 along the first direction, the limiting surface 321 is provided with a limiting groove 322, and the interlocking mechanism can be arranged between two contactors along the first direction. Wherein, the a direction in the figure is the first direction, the first direction can be the width direction of the contactor, the b direction is the second direction, the second direction can be the length direction of the contactor, and the c direction is the third direction, the third direction can be the height direction of the contactor, that is, the first direction, the second direction and the third direction can be arranged perpendicular to each other. In this embodiment, the contact support 320 moves along the third direction and has an open position and a closed position. In the open position, the contactor disconnects the connected external circuit; in the closed position, the contactor conducts the connected external circuit.

[0052] Specifically, the interlocking mechanism includes a guide member 100 and an interlocking member 200. The guide member 100 is provided with a guide hole 110 along the first direction, and the guide member 100 can be connected to the contactor body 310. The interlocking member 200 is inserted into the guide hole 110. The interlocking member 200 is provided with locking parts on both sides along the first direction. The locking parts include a first locking surface 201 and a locking protrusion 202. The locking protrusion 202 is provided along the first direction protruding from the first locking surface 201. The interlocking mechanism can make the contact supports 320 of the two contactors have an unlocked state and an interlocked state.

[0053] Specifically, the first direction may be the extending direction of the axis of the guide hole 110 .

[0054] In the unlocked state, the interlocking member 200 can move in the guide hole 110 along the first direction. In the unlocked state, the contact supports 320 of the two contactors are both in the disconnected position. In this embodiment, in the unlocked state, when the contact support 320 of one contactor is switched to the closed position, the interlocking member 200 can move to the contact supports 320 of the two contactors to form an interlock. Exemplarily, during the process of switching one contact support 320 to the closed position, the groove wall of the limiting groove 322 of the contact support 320 can squeeze the locking protrusion 202 on the corresponding side, so that the interlocking member 200 moves toward the other contact support 320 along the first direction until the locking protrusion 202 on the other side is inserted into the limiting groove 322 and forms an interlock. In the first direction, the distance L1 between the ends of the two locking protrusions 202 is greater than the length L2 of the guide hole 110 along the first direction. Of course, the movement of the interlocking member 200 can also be achieved by manually pushing the interlocking member 200 in the guide hole 110 along the first direction, or by applying electromagnetic force to the interlocking member 200 to move the interlocking member 200 in the guide hole 110, etc., and this application does not make any limitation.

[0055] In a possible implementation, Figures 5 to 7 As shown, the locking protrusion 202 includes two second locking surfaces 2021 arranged at an angle, and the groove wall of the limiting groove 322 can squeeze the second locking surface 2021 located at the upper side of the corresponding side, so that the interlocking member 200 moves along the first direction, effectively preventing the occurrence of the stuck phenomenon. Exemplarily, the angle between the two second locking surfaces 2021 of the locking protrusion 202 can range from 60° to 150°, such as 75°, 90°, 110°, 120° or 135°. Of course, the locking protrusion 202 can also be set in a hemispherical or semi-cylindrical shape.

[0056] In the interlocked state, the first locking surface 201 of one of the two locking parts abuts against the limiting surface 321 of the contact support 320 in the disconnected position along the first direction, and the locking protrusion 202 is inserted into the limiting groove 322; the locking protrusion 202 of the other one abuts against the limiting surface 321 of the contact support 320 in the closed position, effectively preventing the locking protrusion 202 from escaping from the limiting groove 322, thereby preventing the contact support 320 in the disconnected position from switching to the closed position. Moreover, during the closing or opening of the contactor, the wear between the first locking surface 201 and the limiting surface 321 is small. By setting the first locking surface 201 to abut against the limiting surface 321 along the first direction, even if wear occurs between the locking protrusion 202 and the groove wall of the limiting groove 322, the part of the interlocking member 200 other than the locking protrusion 202 will not be inserted into the limiting groove 322, effectively preventing the interlocking member 200 from getting stuck with the limiting groove 322, thereby ensuring the normal use of the contactor.

[0057] In this embodiment, refer to Figure 1 , Figure 3 and Figure 4 As shown, both sides of the guide member 100 along the first direction are provided with plug-in parts 120, and the plug-in parts 120 can be plugged into the contactor body 310, which is convenient for assembly and effectively ensures that the connection between the guide member 100 and the contactor body 310 is stable and reliable.

[0058] In this embodiment, refer to Figures 7 to 10 As shown, the interlocking member 200 includes a locking block 210 and guide blocks 220 arranged on both sides of the locking block 210 along the second direction, a locking protrusion 202 is arranged on the locking block 210, and a first locking surface 201 is arranged on the guide block 220; the guide hole 110 includes a first hole portion 111 and a second hole portion 112 arranged on both sides of the first hole portion 111 along the second direction, the locking block 210 is passed through the first hole portion 111, and the guide block 220 on the corresponding side is passed through the second hole portion 112, which effectively ensures that the interlocking member 200 moves stably in the guide hole 110 to prevent jamming, and each guide block 220 is provided with a first locking surface 201, which can more effectively prevent the part of the interlocking member 200 other than the locking protrusion 202 from being inserted into the limiting groove 322.

[0059] In a feasible embodiment, the locking block 210 may include a first give-way surface 211 relatively arranged along a third direction, and the first hole portion 111 includes a second give-way surface 1111 relatively arranged along the third direction, and gaps are formed between the first give-way surface 211 and the second give-way surface 1111 on the corresponding side, respectively, to effectively prevent the locking protrusion 202 from being worn during the movement of the locking block 210 in the first hole portion 111, so that the mechanical interlocking of the two contactors by the interlocking mechanism is stable and reliable, and the service life of the interlocking mechanism is effectively improved.

[0060] Specifically, the distance between the two first making way surfaces 211 is set to H1, and the distance between the two second making way surfaces 1111 is set to H2; wherein H1<H2.

[0061] Further, the guide block 220 may include first guide surfaces 221 arranged opposite to each other along the third direction, and the second hole portion 112 includes second guide surfaces 1121 arranged opposite to each other along the third direction, and the distance between the two first guide surfaces 221 is set to H3, and the distance between the two second guide surfaces 1121 is set to H4; wherein, H3<H4; H4-H3<H2-H1. In this embodiment, since H4-H3<H2-H1, while preventing the locking protrusion 202 from being worn during the movement of the locking block 210 in the first hole portion 111, the guide block 220 cooperates with the second hole portion 112 to guide the movement of the interlocking member 200 along the first direction; and since H3<H4, a gap is formed between the guide block 220 and the second hole portion 112 along the third direction, thereby ensuring that the guide block 220 moves more smoothly relative to the second hole portion 112. In addition, in the unlocked state, when the contact support 320 of a contactor is switched from the open position to the closed position, because H4-H3<H2-H1, the groove wall of the limiting groove 322 of the contact support 320 squeezes the locking protrusion 202 on the corresponding side, which can make the guide block 220 tilt, effectively reducing the friction and wear between the groove wall of the limiting groove 322 and the locking protrusion 202, and effectively preventing the groove wall of the limiting groove 322 and the locking protrusion 202 from getting stuck.

[0062] In a feasible embodiment, the locking block 210 includes two first end faces 212 arranged opposite to each other along the second direction, and the first hole portion 111 includes two third yielding surfaces 1112 arranged opposite to each other along the second direction, and a gap is formed between the first end face 212 and the third yielding surface 1112 on the corresponding side, which effectively prevents the locking protrusion 202 from being worn during the movement of the locking block 210 in the first hole portion 111, thereby effectively improving the service life of the interlocking mechanism; and in the interlocking state, a larger contact area can be maintained between the locking protrusion 202 and the limiting groove 322 of the contact support 320 in the disconnected position, thereby effectively preventing the locking protrusion 202 from breaking.

[0063] Specifically, the distance between the two first end surfaces 212 is set to B1, and the distance between the two third giving way surfaces 1112 is set to B2; wherein B1<B2.

[0064] Furthermore, the two guide blocks 220 include a second end face 222 facing away from the locking block 210 along the second direction, the second hole portion 112 includes a third guide surface 1122 arranged along the second direction, the distance between the second end faces 222 of the two guide blocks 220 is set to B3, and the distance between the two third guide surfaces 1122 is set to B4; wherein, B3<B4; B4-B3<B2-B1. In this embodiment, since B4-B3<B2-B1, even if the locking member is skewed, the first end face 212 will not contact and wear the third clearance surface 1112 on the corresponding side, since B3<B4, so that a gap is formed along the second direction between the guide block 220 and the second hole portion 112, thereby ensuring that the guide block 220 moves more smoothly relative to the second hole portion 112.

[0065] Reference Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, this embodiment also provides a contactor assembly, which includes the above-mentioned interlocking mechanism and a contactor. Through the specific structural design of the interlocking mechanism, the interlocking mechanism and the contactor are effectively prevented from getting stuck, ensuring the normal use of the contactor, which is stable and reliable. Among them, at least two contactors are provided along the first direction, and an interlocking mechanism is provided between two adjacent contactors.

[0066] Specifically, the contactor body 310 is provided with a docking portion 311 on both sides along the first direction, the docking portion 311 includes two docking blocks 3111 spaced apart along the second direction, the docking blocks 3111 are provided with a plug hole 3101, and the plug-in portion 120 includes plug-in protrusions 121 spaced apart along the second direction, and the plug-in protrusions 121 are plugged into the corresponding plug holes 3101 one by one to achieve the connection between the contactor body 310 and the guide member 100. During assembly, the guide member 100 can be plugged into one contactor body 310 first, and then the interlocking member 200 can be placed in the guide hole 110, and finally the guide member 100 can be plugged into another contactor body 310. Further specifically, the contact support 320 is provided with a limit surface 321 on both sides along the first direction.

[0067] Specifically, the limiting groove 322 may include two inclined groove surfaces 3221 set at an angle, and the inclined groove surfaces 3221 are set one-to-one with the second locking surfaces 2021. The upper inclined groove surface 3221 squeezes the corresponding side of the second locking surface 2021 located above to make the interlocking member 200 move along the first direction.

[0068] In a feasible implementation, the angle between the two inclined groove surfaces 3221 of the limiting groove 322 is greater than the angle between the two second locking surfaces 2021 of the locking protrusion 202. In the interlocking state, the inclined groove surface 3221 at the bottom of the limiting groove 322 of the contact support 320 in the disconnected position abuts against the second locking surface 2021 at the bottom of the locking protrusion 202 on the corresponding side, so as to prevent wear between the upper inclined groove surface 3221 and the second locking surface 2021, thereby effectively improving the service life of the interlocking mechanism.

[0069] For example, in the unlocked state, when the contact support 320 of one contactor is switched from the open position to the closed position, first, the upper inclined groove surface 3221 of the limiting groove 322 of the contact support 320 presses the upper second locking surface 2021 of the corresponding side, and the interlocking member 200 moves toward the other contactor until the lower second locking surface 2021 of the locking protrusion 202 on the other side abuts against the lower inclined groove surface 3221 of the limiting groove 322 on the corresponding side, thereby realizing the interlocking between the two contact supports 320, that is, the contact support 320 of the other contactor cannot be switched to the closed position under the limiting position of the interlocking member 200. In this process, there is almost no wear between the first locking surface 201 and the limiting surface 321 on the corresponding side.

[0070] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
