When the existing isolating switch is in a closing state, a cover cap at a fuse can be normally opened, and great potential safety hazards exist. And when the cover cap at the fuse is opened and the fusible core of the fuse is replaced, the isolating switch can perform switching-off or switching-on operation, and larger potential safety hazards exist. In view of the above problems, the embodiments of the present application provide the following solutions to overcome the above problems, thereby reducing potential safety hazards and improving the safety of power consumption.

Referring to fig. 1 and 2, an interlocking mechanism 100 according to an embodiment of the present disclosure includes a housing 110, a cover cap 120, and a first sliding member 130 and a second sliding member 140 slidably connected to the housing 110, respectively, wherein the first sliding member 130 is used for connecting with an operating handle 160 of an operating mechanism, and the second sliding member 140 is provided with an elastic member 150, so that the second sliding member 140 has an elastic force close to the cover cap 120; when the operating mechanism is in a closing state, the cover cap 120 covers the housing 110 and is clamped with the first sliding part 130; when the cover cap 120 is separated from the housing 110, the operating mechanism is in the open state, and the first sliding member 130 is engaged with the second sliding member 140.

In an example, the housing 110 and the cover 120 are in a covered state, that is, in a separated state, and under a condition that the disconnector normally works, the housing 110 and the cover 120 are in the covered state, so as to ensure safety of the disconnector during use. When it is necessary to replace the fusible core of the fuse mounted in series in the disconnecting switch, the cover 120 needs to be opened to separate the housing 110 from the cover 120, thereby facilitating the replacement of the fusible core. The housing 110 and the cover 120 may be hinged or clamped, and may be flexibly disposed according to actual requirements.

The second sliding member 140 is provided with an elastic member 150, so that the second sliding member 140 has an elastic force close to the first sliding member 130 and the cover cap 120, wherein the elastic member 150 may be disposed between the first sliding member 130 and the second sliding member 140, or between the housing 110 and the second sliding member 140. When the elastic member 150 is disposed between the first sliding member 130 and the second sliding member 140, the first sliding member 130, the second sliding member 140 and the elastic member 150 are modularized, so that the assembly is conveniently performed after the assembly of the first sliding member 130, the second sliding member 140 and the elastic member 150 into a whole, which is beneficial to improving the assembly efficiency and reducing the operation difficulty. It is understood that the elastic member 150 may be disposed between the second slider 140 and the housing 110 as long as it can provide a desired elastic force.

When the first sliding member 130 is connected to the operating handle 160 of the operating mechanism, the operating handle 160 drives the operating mechanism to open and close, and the first sliding member 130 is synchronously driven to reciprocate. When the handle drives the operating mechanism to close, the cover cap 120 and the housing 110 need to be in a covering state, otherwise, the first slider 130 and the second slider 140 are in a clamping state, and the first slider 130 cannot move, so that the operating handle 160 is in a clamping state and cannot be closed. When the cover 120 and the housing 110 are in a closed state, the operating handle 160 can drive the operating mechanism to perform an opening or closing operation, and at this time, if the operating mechanism is in an opening state, the cover 120 and the first slider 130 are disengaged, and the cover 120 can be opened to be separated from the housing 110. If the operating mechanism is in a closing state, the first sliding member 130 is clamped with the cover cap 120, the cover cap 120 cannot be opened, and the cover cap is in a closing state with the shell 110, which is beneficial to ensuring the power utilization safety.

According to the interlocking mechanism 100 provided by the embodiment of the application, the first sliding part 130 is connected with the operating handle 160 through the first sliding part 130 and the second sliding part 140 which are respectively connected with the housing 110 in a sliding manner, and in the process of controlling the opening or closing of the operating mechanism through the operating handle 160, the first sliding part 130 is driven to slide relative to the housing 110, so that the first sliding part 130 and the cover cap 120 can be clamped or released from being clamped. The elastic member 150 disposed between the first slider 130 and the second slider 140 enables the second slider 140 to have an elastic force close to the cover cap 120, when the cover cap 120 is covered with the housing 110, the second slider 140 is abutted against the cover cap 120, and when the operating mechanism is in a closed state, the first slider 130 is clamped with the cover cap 120. When the operating mechanism is in the open state and the cover cap 120 is separated from the housing 110, the elastic member 150 releases the elastic potential energy, so that the second slider 140 slides relative to the housing 110 and is clamped with the first slider 130, thereby preventing the operating mechanism from being closed when the cover cap 120 is separated from the housing 110 (the cover cap 120 is opened). Adopt above-mentioned form, can be when shroud 120 opens, can't carry out the combined floodgate operation to when being in combined floodgate state, shroud 120 can't open, thereby reduces the potential safety hazard, guarantees the operation safety, promotes the security of power consumption.

As shown in fig. 2, 3 and 4, the first slider 130 comprises a connecting arm 132 and a snap arm 134 connected to each other, wherein the connecting arm 132 is adapted to be connected to the operating handle 160 and the snap arm 134 is adapted to be snapped into the cover cap 120 or the second slider 140, respectively.

Specifically, the structural form of the operating handle 160 is not particularly limited in the embodiment of the present application, as long as the manual opening and closing operation can be performed, and the first sliding part 130 is driven to slide relative to the housing 110. For example, the operating handle 160 may be configured as shown in FIG. 3, or may be configured in other ways, such as by connecting the operating handle to a rotating member, or by connecting the operating handle to a linkage.

In addition, the number of the connecting arms 132 is not particularly limited in the embodiment of the present application, and for example, the connecting arms 132 may be provided as two opposite or only one, as long as the stability of the connection of the first sliding member 130 can be ensured. Since the connecting arm 132 is connected to the operating handle 160, the connecting arm 132 and the latch arm 134 are simultaneously actuated when the operating handle 160 is actuated. Meanwhile, the connecting arm 132 and the snap-fit arm 134 may also act on the operating handle 160 in reverse to limit the movement of the operating handle 160. For example, in a closed state of the operating mechanism, the cover 120 is buckled with the housing 110, and the snap arm 134 is snapped with the cover 120. When the cover 120 is engaged with the housing 110, the operating mechanism can perform an opening or closing operation to drive the connecting arm 132 to move synchronously. When the cover 120 is separated from the housing 110, the second slider 140 is engaged with the engaging arm 134, so that the engaging arm 134 restricts the movement of the operating handle 160 through the connecting arm 132, and the operating mechanism cannot be closed.

As shown in fig. 3 and 4. The connecting arm 132 is provided with a first groove 1322, the operating handle 160 is provided with a first protrusion 162 engaged with the first groove 1322, or the connecting arm 132 is provided with a first protrusion 162, and the operating handle 160 is provided with a first groove 1322 engaged with the first protrusion 162.

Specifically, by providing the first recess 1322 on the connecting arm 132 and providing the first protrusion 162 on the operating handle 160, when the operating handle 160 and the operating mechanism rotate relatively to each other to control the opening or closing of the operating mechanism, the first protrusion 162 rotates synchronously with respect to the rotation center of the operating handle 160. Since the first protrusion 162 is clamped in the first recess 1322, when the first protrusion 162 rotates synchronously with respect to the rotation center of the operating handle 160, the first protrusion abuts against the inner wall of the first recess 1322, so as to drive the connecting arm 132 to slide with respect to the housing 110. For example, in the process that the operating handle 160 drives the operating mechanism to close the switch, the first protrusion 162 rotates synchronously with the operating handle 160, at this time, the first protrusion 162 abuts against one side wall of the first groove 1322, and while providing the abutting force required for sliding the connecting arm 132, the first protrusion 162 and the side wall of the first groove 1322 slide relatively, so that the first groove 1322 needs to have a certain depth to prevent the first protrusion 162 and the first groove 1322 from being disengaged from a clamping state or interfering with each other and being clamped when sliding relatively. Similarly, when the operating handle 160 drives the operating mechanism to open the brake, the first protrusion 162 rotates synchronously with the operating handle 160, and at this time, the first protrusion 162 abuts against the other side wall of the first recess 1322 to provide the abutting force required for the reverse sliding of the connecting arm 132. It should be noted that, when the connecting arm 132 is provided with the first protrusion 162, and the operating handle 160 is provided with the first recess 1322 engaged with the first protrusion 162, the above-mentioned form is the same, and the description is omitted here.

As shown in fig. 2 and 5, the cover 120 includes snap portions 122 respectively snap-engaged with the snap arms 134, and snaps 124 snap-engaged with the housing 110.

Specifically, when the cover 120 is closed with the housing 110, in order to ensure the stability of the closing, the cover 120 is engaged with the housing 110 by the engaging member 124, so as to prevent the cover 120 and the housing 110 from being accidentally separated due to external factors such as vibration when the engaging arm 134 and the engaging portion 122 are released from the engaged state. The clamping portion 122 is used for making the clamping portion 122 and the clamping arm 134 clamped in the process that the first sliding member 130 is close to the cover cap 120, and the setting form of the clamping portion 122 is not specifically limited in the embodiment of the application, for example, the clamping portion 122 can be a clamping groove formed in the position of the cover cap 120, and can also be a cavity into which the clamping arm 134 extends, as long as the effect of limiting the clamping of the cover cap 120 can be achieved.

As shown in fig. 5 and 6, the second sliding member 140 is provided with a limiting protrusion 142, the engaging arm 134 is correspondingly provided with a limiting groove 1342, and when the cover cap 120 is separated from the housing 110, the limiting protrusion 142 is engaged with the limiting groove 1342.

Specifically, with the above structure, the cover cap 120 can be separated from the housing 110 only when the operating mechanism of the disconnecting switch is in the open state, and when the cover cap 120 is separated from the housing 110, the second sliding member 140 does not abut against and limit the second sliding member 140, and the second sliding member 140 slides in the direction of the cover cap 120 under the action of the elastic member 150, so that the limiting protrusion 142 on the second sliding member 140 is clamped with the limiting groove 1342 on the clamping arm 134. In this way, after the disconnecting switch is opened and the cover 120 is opened, the second slider 140 slides relative to the housing 110 under the action of the elastic member 150 and is clamped with the first slider 130, so that the first slider 130 limits the movement of the operating handle 160, and the operating mechanism is prevented from being closed by the operating handle 160 in a state where the cover 120 is separated from the housing 110, thereby preventing potential safety hazards.

As shown in fig. 1 and fig. 5, the second sliding member 140 is further provided with a support column 144, and when the cover cap 120 covers the housing 110, the cover cap 120 supports against the support column 144, so that the limit protrusion 142 and the limit groove 1342 are released from the clamping state.

Specifically, the height of the abutting column 144 should be higher than the height of the limiting protrusion 142, when the cover cap 120 covers the housing 110, the cover cap 120 abuts against the abutting column 144, and the operating mechanism can perform a switching-off or switching-on operation, during the switching-off or switching-on operation, the first slider 130 slides back and forth, and the sliding range of the clamping arm 134 is located in the space between the limiting protrusion 142 and the abutting column 144, that is, the limiting protrusion 142 is in a state of contacting and clamping with the limiting groove 1342. It should be noted that, in the embodiment of the present application, the number of the supporting columns 144 is not specifically limited, for example, only one supporting column 144 may be provided, or two supporting columns 144 may be provided, as long as the structural strength of the supporting columns 144 and the cover cap 120 can be ensured to form a stable supporting relationship.

In an alternative embodiment of the present application, the sliding directions of the first sliding member 130 and the second sliding member 140 form a predetermined included angle. For example, the first sliding member 130 can slide along the length direction of the disconnector, and the second sliding member 140 can slide along the width direction of the disconnector, where the sliding directions of the first sliding member 130 and the second sliding member 140 form an angle of 90 °. It can be understood that, according to actual needs, the first sliding member 130 can slide along the length direction of the disconnector, and the sliding direction of the second sliding member 140 has an angle with the width direction of the disconnector. At this time, an included angle between the sliding directions of the first and second sliding members 130 and 140 may be between 80 ° and 100 °. Of course, the first sliding member 130 may slide in the direction deviating from the longitudinal direction, and the second sliding member 140 may slide in the width direction; the first slider 130 may slide in a direction deviating from the longitudinal direction, and the second slider 140 may slide in a direction deviating from the width direction, as long as it is ensured that the first slider 130 and the second slider 140 are released from the engagement state in a state where the cover cap 120 and the housing 110 are closed, so that the operating handle 160 can normally control the operating mechanism to perform switching on and off, and the first slider 130 and the cover cap 120 are engaged in a switching on state, and the cover cap 120 can be opened in a switching off state, and the first slider 130 and the second slider 140 are engaged in a switching off state when the cover cap 120 and the housing 110 are separated.

As shown in fig. 5, 6 and 7, the connecting arm 132 is provided with a first ear plate 1324, the inner wall of the housing 110 is provided with a first sliding slot 112 corresponding to the first ear plate 1324, and the first ear plate 1324 slides along the first sliding slot 112; the second sliding member 140 is provided with a second ear plate 146, the inner wall of the housing 110 or the vertical plate 170 of the operating mechanism is provided with a second sliding slot corresponding to the second ear plate 146, and the second ear plate 146 slides along the second sliding slot.

Specifically, the first slider 130 and the second slider 140 may be made of sheet metal, and the first ear panel 1324 and the second ear panel 146 may be formed in a sheet metal bending manner. By adopting the mode, the clamping connection structure is beneficial to ensuring the structural strength when the first sliding piece 130 is clamped with the second sliding piece 140 or the cover cap 120 is clamped, and the failure caused by insufficient strength of parts is prevented. The first ear plate 1324 or the second ear plate 146 may also be bent inward as required, so that the first sliding member 130 or the second sliding member 140 is slidably connected to the vertical plate of the operating mechanism. It will be appreciated that, to reduce the cost of use, injection-moulded parts may also be used, provided that the required structural strength is ensured.

As shown in fig. 5 and 6, in an alternative embodiment of the present application, the second sliding member 140 is further provided with a third ear plate 148 disposed parallel to the second ear plate 146, and the third ear plate 148 is configured to abut against one side of the vertical plate 170. Thus, the structural strength of the second sliding member 140 is improved, when the second ear plate 146 slides along the second sliding groove, the third ear plate 148 abuts against one side of the vertical plate 170, and the vertical plate 170 slides relatively, so that the lateral force applied to the second ear plate 146 when sliding along the second sliding groove is dispersed, the stress deformation of the second ear plate 146 is avoided, and the stability of the interlocking mechanism 100 during movement is ensured.

As shown in fig. 4 and 7, the connecting arm 132 is further provided with a first positioning hole 1326, and the vertical plate 170 of the operating mechanism is provided with a second positioning hole corresponding to the first positioning hole 1326, so that the positioning shaft is inserted into the first positioning hole 1326 and the second positioning hole. By adopting the above form, when assembling the interlocking mechanism 100, the first positioning hole 1326 and the second positioning hole can be corresponded first, and the first sliding member 130 and the vertical plate 170 are temporarily fixed relatively by the positioning shaft, so that the relative sliding is avoided during the assembling, the operation difficulty is reduced, and the assembling efficiency is improved.

In alternative embodiments of the present application, the elastic member 150 is disposed between the first slider 130 and the second slider 140, or the elastic member 150 is disposed between the second slider 140 and the housing 110. When the elastic member 150 is connected between the first slider 130 and the second slider 140, the elastic member 150 is a tension spring or an elastic string so that the second slider 140 has an elastic force close to the cover 120. At this time, it is advantageous for the interlocking mechanism 100 to form a modular mounting structure to improve assembly efficiency. It is understood that, when the elastic member 150 is disposed between the housing 110 and the second slider 140, the elastic member 150 may be a compression spring, a torsion spring, an extension spring, or the like, as long as it can provide an elastic force to make the second slider 140 approach the cover 120.

As shown in fig. 8, the embodiment of the present application further discloses a disconnecting switch 200, which includes the interlocking mechanism 100 in the foregoing embodiment. The cover 120 is provided on the housing 110, and is engaged with the interlock mechanism 100, so that the closing operation is disabled when the cover is opened, and the opening of the cover is disabled when the cover is in the closed state. The isolation switch 200 includes the same structure and advantages as the interlock mechanism 100 in the previous embodiment. The structure and advantages of the interlocking mechanism 100 have been described in detail in the foregoing embodiments, and are not described in detail herein.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
