Description

Technical Field

[0001] This invention relates to the field of switch technology, and in particular to an electrical switch device. Background Technology

[0002] Electrical switches are often used for opening and closing circuits and for circuit protection. In related technologies, electrical switches are mounted on a sliding rail. The back of the electrical switch has two latches that engage with the two sides of the sliding rail. To install the electrical switch onto the rail, align the latches of the electrical switch with one end of the rail, insert the sliding rail between the two latches, and then install the electrical switch.

[0003] Regarding the aforementioned technologies, since multiple electrical switches are installed on the rail and are closely arranged, when one of the electrical switches in the middle is damaged and needs to be replaced, the electrical switches on one side of the damaged electrical switch need to be removed one by one before the damaged electrical switch can be replaced. Then the removed electrical switches are installed one by one, which is quite troublesome and causes the problem of inconvenient disassembly and assembly of electrical switches. Summary of the Invention

[0004] To address the inconvenience of assembling and disassembling electrical switches, this application provides an electrical switch device.

[0005] The electrical switchgear provided in this application adopts the following technical solution:

[0006] An electrical switch device includes a switch body mounted on a track. A fixed locking block and a movable locking block are connected to one end face of the switch body near the track. The fixed locking block is located at one end of the switch body end face, and the movable locking block is located at the other end of the switch body end face. A fixed locking slot is provided on the side of the fixed locking block near the movable locking block. A movable locking plate is inserted into the movable locking block and slidably connected within it. One end of the movable locking plate near the fixed locking block extends out of the movable locking block. A movable locking slot is provided on the end of the movable locking plate near the fixed locking slot. The track engages between the fixed locking slot and the movable locking slot. An elastic element is provided on the movable locking plate for engaging the movable locking slot with the track.

[0007] By adopting the above technical solution, when installing the switch body, first align the fixing slot of the fixing block with the side of the rail, and the side of the rail is inserted into the fixing slot. Then, press down on the switch body to move the movable block closer to the rail, driving the movable plate away from the fixing slot and compressing the elastic element. When the switch body abuts against the rail, the constraint on the movable plate is released. Under the push of the elastic element, the movable plate moves towards the fixing slot, and the other side of the rail is engaged in the sliding slot, thus fixing the switch body on the rail. When the switch body is damaged and needs to be replaced, drive the movable plate away from the fixing block to release the engagement between the rail and the movable slot. Lift the switch body and push it towards the side of the fixing block to disassemble the switch body. There is no need to disassemble the switch on the side of the switch body, thus improving the problem of inconvenient disassembly and assembly of electrical switches.

[0008] Optionally, the movable locking block includes two limiting strips, which are respectively located on both sides of the end face of the switch body. Each of the two limiting strips has a sliding groove on its side closest to each other, and the movable locking plate slides along the inner walls of the two sliding grooves. The movable locking plate has a through hole. The elastic element includes an elastic strip and a locking head. One end of the elastic strip is connected to the side wall of the through hole, and the locking head is connected to the end of the elastic strip. The locking head extends out of the movable locking plate near the switch body, and the end of the locking head away from the elastic strip is inclined, with the inclined surface facing the movable locking opening. The side of the switch body near the movable locking plate has a locking groove, and the locking head engages in the locking groove.

[0009] By adopting the above technical solution, when disassembling and assembling the switch body, the movable locking plate is moved within the slide groove to achieve the engagement of the movable locking slot with the locking rail. The locking head engages within the locking groove, restricting the end of the elastic strip. When the movable locking plate is pushed by an external force, it causes the end of the elastic strip away from the locking head to move, causing the elastic strip to bend and the movable locking plate to slide into the slide groove. When the external force on the movable locking plate is removed, the elastic strip returns to its original position, and the elastic locking strip pushes the movable locking plate towards the fixed locking block. The movable locking slot of the movable locking strip engages with the side of the locking rail, realizing the reciprocating operation of the movable locking plate, making the operation more convenient.

[0010] Optionally, an elastic block is connected to the inner wall of the through hole, and a protrusion is provided on the side of the elastic block near the switch body. A ridge is provided on the side of the switch body near the movable plate, and the ridge is located on the side of the protrusion away from the fixed block.

[0011] By adopting the above technical solution, when the movable card plate is subjected to external force and moves away from the fixed card block, the elastic strip bends elastically, the protrusion of the elastic block moves towards the convex strip, the protrusion abuts against the convex strip, the protrusion is restricted from continuing to move, the movable card plate is restricted from continuing to move, thereby preventing the elastic strip from driving the card head out of the card slot, so that the movable card plate can be reset.

[0012] Optionally, the end of the movable plate away from the fixed plate extends out of the switch body and is provided with a disassembly port at the end. The disassembly port is located outside the switch body and is used to pull the movable plate out between the two limiting strips.

[0013] By adopting the above technical solution, when installing the movable card plate, align the movable card plate with the slide groove, insert the movable card block into the slide groove, and the card head is squeezed by the switch body, causing the elastic strip to bend elastically until the card head is locked into the slot; when it is necessary to remove the movable card plate, hold the disassembly port with your fingers and pull the movable card plate outward. The card head is squeezed, causing the elastic strip to bend elastically, and the card head slides out of the slot, so the movable card plate can be disassembled, thereby improving the convenience of disassembling and assembling the movable card plate.

[0014] Optionally, the fixed block has a first guide surface on the side away from the movable block, and the first guide surface is opposite to the switch body.

[0015] By adopting the above technical solution, when installing the switch body, the switch body needs to be tilted. Since the first guide surface is provided on one side of the fixing block, the first guide surface is first put against the inner wall of the box connected by the card rail, and then the switch body is pushed towards the card rail so that the fixing slot is engaged with the side of the card rail. The first guide surface makes it easy to engage the fixing slot with the side of the card rail.

[0016] Optionally, a guide block is connected to the side of the movable card plate away from the switch body. The guide block is located at the end of the movable card plate near the fixed card block. The guide block slides between the two limit strips. A second guide surface is provided on the side of the guide block near the fixed card block. The second guide surface is inclined and faces away from the movable card slot.

[0017] By adopting the above technical solution, when the fixed latch is engaged with one side of the rail, pressing down on the switch body causes the movable latch block to move towards the other side of the rail, and the movable latch plate also moves towards the other side of the rail. The side of the rail abuts against the second guide surface of the movable latch plate. Continuing to press down on the switch body causes the side of the rail to continue pressing against the second guide surface, causing the movable latch plate to retract into the groove. The movable latch plate, along with the elastic strip, bends elastically until the rail abuts against the side of the switch body. Under the elastic reset action of the elastic strip, the movable latch plate moves towards the rail, and the movable latch engages with the side of the rail, fixing the switch body. There is no need for personnel to manually pull the movable latch plate. The second guide surface facilitates the installation of the switch body, improving the ease of installation.

[0018] Optionally, a limiting block is connected to one side of the two limiting strips that are close to each other. The limiting block is located on the side of the guide block away from the fixed block. A third guiding surface is provided on the side of the limiting block away from the fixed block, and the third guiding surface faces the other limiting strip.

[0019] By adopting the above technical solution, when the movable card plate is subjected to external force and moves away from the fixed card block, the elastic strip bends elastically, the guide block moves towards the limit block, the guide block abuts against the limit block, the guide block is restricted from continuing to move, the movable card plate is restricted from continuing to move, thereby preventing the elastic strip from driving the card head out of the card slot, so that the movable card plate can be reset.

[0020] Optionally, the switch body includes a first side cover, a second side cover, a top cover, and positioning blocks. Two side plates and a bottom plate are connected to the periphery of one side of the first side cover. The bottom plate is located on the side of the first side cover near the guide rail. The two side plates are located on opposite sides of the first side cover, and the ends of the two side plates near the bottom plate are connected to both ends of the bottom plate. The second side cover is fastened to the side of the side plates and bottom plate away from the first side cover. Each of the two side plates has a retaining strip on its adjacent side. Two positioning plates are connected to one side of the top cover, located at opposite ends of the top cover. Positioning grooves are provided on the opposite side of the two positioning plates. The top cover is fastened to the side plate away from the bottom plate, and the retaining strips are engaged in the positioning grooves. There are two positioning blocks, each located on opposite sides of the first side cover, used to fix the first and second side covers together.

[0021] By adopting the above technical solution, the circuit board is installed in the housing composed of the first side cover, side plate and bottom plate, the positioning plate is inserted between the two side plates, the clip is inserted into the positioning groove, the top cover is fastened to the end of the first side cover and side plate, the second side cover is fastened to one side of the side plate and bottom plate, and the first side cover and the second side cover are connected by the positioning block, so that the switch body can be assembled, which facilitates the installation of the circuit board.

[0022] Optionally, the positioning block has a side edge connected to one side of the switch body. The side edge is set along the side edge of the positioning block. Each of the two side edges that are close to each other has a locking hole. The side of the first side cover and the second side cover that are far apart from each other has a flange that is engaged in the locking hole. Each of the two side edges that are close to each other has a protrusion. The side of the first side cover and the second side cover that are far apart from each other has a notch that is engaged in the notch.

[0023] By adopting the above technical solution, when the positioning block connects the first side cover and the second side cover, the side edge is fastened to the first side cover and the second side cover, and the protrusion is inserted into the notch and the flange is engaged with the card hole. The two positioning blocks fix the first side cover and the second side cover, realizing the quick installation of the switch body; similarly, by releasing the engagement state of the flange and the card hole, and releasing the insertion state of the protrusion and the notch, the quick disassembly of the switch body can be realized.

[0024] Optionally, each of the side plates is connected to a first elastic plate on one side away from each other. A first guide block is provided on one side of the end of the first elastic plate. A second elastic plate is connected to the side of the positioning block near the switch body. A second guide block is provided on one side of the end of the second elastic plate. The first guide block is engaged with the second guide block.

[0025] By adopting the above technical solution, when the positioning block engages with the first and second side covers, the first elastic plate moves closer to the second elastic plate, the first guide block abuts against the second guide block, and the positioning block continues to be pushed. The first and second elastic plates undergo elastic bending, and the positioning block continues to be pushed. The second guide block passes over the first guide block, and the first and second elastic plates reset, realizing the mutual engagement between the first and second guide blocks. This makes the protrusion inserted into the notch and the flange engaged in the locking hole more secure, improving the stability of the connection between the fixing block and the first and second side covers.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. When installing the switch body, first align the fixing slot of the fixing block with the side of the rail. The side of the rail will then engage with the fixing slot. Next, press down on the switch body to move the movable block closer to the rail, driving the movable plate away from the fixing slot and compressing the elastic element. When the switch body abuts against the rail, release the constraint on the movable plate. Under the push of the elastic element, the movable plate moves towards the fixing slot, and the other side of the rail engages with the sliding slot, thus fixing the switch body on the rail. When the switch body is damaged and needs to be replaced, drive the movable plate away from the fixing block to release the engagement between the rail and the movable slot. Lift the switch body and push it towards the fixing block to disassemble the switch body. This allows for disassembly without disassembling the switch on the side of the switch body, thus improving the inconvenience of electrical switch assembly and disassembly.

[0028] 2. When disassembling and assembling the switch body, the movable locking plate is moved within the slide groove to engage with the sliding rail. The locking head engages within the slot, restricting the end of the elastic strip. When the movable locking plate is pushed by an external force, it moves the end of the elastic strip away from the locking head, causing the elastic strip to bend and the movable locking plate to slide into the slide groove. When the external force on the movable locking plate is removed, the elastic strip returns to its original position, and the elastic locking strip pushes the movable locking plate towards the fixed locking block. The movable locking head of the movable locking strip engages with the side of the sliding rail, enabling the reciprocating operation of the movable locking plate, making operation more convenient.

[0029] 3. When the movable plate is subjected to external force and moves away from the fixed plate, the elastic strip bends elastically, the protrusion of the elastic block moves towards the convex strip, and the protrusion abuts against the convex strip. The protrusion is restricted from continuing to move, and the movable plate is restricted from continuing to move. This can prevent the elastic strip from driving the plate head out of the slot, so that the movable plate can be reset. Attached Figure Description

A protrusion 72 is integrally formed on the side of the first segment 701 close to the movable card plate 3. The protrusion 72 is located on the side of the protrusion 331 away from the fixed card block 1.

[0053] Reference Figure 7 and Figure 8 The two limiting strips 21 are integrally formed with limiting blocks 212 on the side that are close to each other. The limiting blocks 212 are located on the side of the guide block 35 away from the fixed block 1. The side of the limiting block 212 away from the fixed block 1 is provided with a third guide surface 2121, which faces the other limiting strip 21.

[0054] When the movable card plate 3 is subjected to an external force and moves away from the fixed card block 1, the elastic strip 321 bends elastically, and the protrusion 331 of the elastic block 33 moves toward the protrusion 72. The protrusion 331 abuts against the protrusion 72, and the protrusion 331 is restricted from continuing to move. The movable card plate 3 is also restricted from continuing to move. At the same time, the guide block 35 moves toward the limiting block 212, and the guide block 35 abuts against the limiting block 212. The guide block 35 is also restricted from continuing to move. The movable card plate 3 is also restricted from continuing to move. This can prevent the elastic strip 321 from driving the card head 322 out of the card slot 71, so that the movable card plate 3 can be reset.

[0055] Reference Figure 7 and Figure 8The movable card plate 3 has an integrally formed disassembly part 34 at the end away from the fixed card block 1. The disassembly part 34 is located outside the slide groove 211 and abuts against the end of the limit strip 21 away from the fixed card block 1. The disassembly part 34 is provided with a disassembly port 341, which is used to pull the movable card plate 3 out between the two limit strips 21.

[0056] When the movable card plate 3 is inserted into the slide groove 211, the inclined surface of the card head 322 first abuts against the second segment 702, causing the card head 322 to drive the elastic strip 321 to bend elastically, making it easy to quickly insert the movable card plate 3 into the slide groove 211; when it is necessary to remove the movable card plate 3 from the slide groove 211, the disassembly port 341 is fastened, the movable card plate 3 is pulled, the elastic strip 321 bends elastically, and the elastic plate is pulled further to make the card head 322 disengage from the card groove 71. The movable card plate 3 is pulled further, the guide block 35 passes the limit block 212, and the protrusion 331 passes the protrusion 72, so that the movable card plate 3 can be removed.

[0057] The implementation principle of an electrical switch device according to an embodiment of this application is as follows: When installing the switch body 02, the switch body 02 is first assembled. The first guide surface 12 is then placed against the inner wall of the housing connected to the rail 01. The switch body 02 is then pushed towards the rail 01, causing the fixing slot 11 to engage with the side of the rail 01. The side of the rail 01 is inserted into the fixing slot 11. The switch body 02 is then pressed down, causing the movable locking block 2 to move closer to the rail 01. The side of the rail 01 abuts against the second guide surface 351, and the side of the rail 01 pushes the movable locking plate 3. The card plate 3 moves away from the fixed card block 1, and the card head 322 engages in the card slot 71. The card head 322 restricts the end of the elastic strip 321. The movable card plate 3 causes the elastic strip 321 to bend, so that the movable card plate 3 slides into the slide groove 211. The side of the card rail 01 passes over the movable card plate 3. Under the action of the elastic strip 321, the movable card plate 3 engages the movable card slot 31 with the side of the card rail 01, realizing the quick installation of the switch body 02 without disassembling the switch on the side of the switch body 02, thereby improving the problem of inconvenient disassembly and assembly of electrical switches.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
