Description

Technical Field

[0001] This utility model relates to the field of electrical equipment, and in particular to a manual maintenance switch. Background Technology

[0002] Some existing manual maintenance switches include a socket and a plug that are connected to each other. The plug is equipped with a lever (or handle). By operating the lever, the plug and socket can be locked or unlocked.

[0003] Chinese utility model patent CN206574623U discloses a novel maintenance switch including a plug upper housing 3, a socket upper housing cover 14, and a plug handle 2 that fixes the plug upper housing 3 and the socket upper housing cover 14 together. The plug upper housing 3 has plug upper housing locking pins 301 and plug upper housing guide grooves 302 on both sides. The socket upper housing cover 14 has socket upper housing cover locking pins 1401 and socket upper housing cover ribs 1402. After the socket upper housing cover 14 is inserted into the plug upper housing 3, it is locked initially by the plug handle connecting plug round holes 201 and plug handle connecting socket grooves 202 located on both sides of the plug handle. The plug handle 2 also has a plug handle buckle 203 in the middle. When the plug handle 2 rotates towards the plug upper housing 3, a plug secondary locking block 1 with a plug secondary locking block buckle 101 inserts into the plug handle buckle 203 and engages with the plug upper housing buckle 303 located on one side of the plug upper housing 3 to form a secondary lock.

[0004] However, the maintenance switch disclosed in the aforementioned utility model patent CN206574623U has a deficiency: it does not limit the order of operation of the primary locking mechanism for achieving primary locking and the secondary locking mechanism for achieving secondary locking. If the secondary locking mechanism is operated before the primary locking mechanism locks, the primary locking mechanism will not be able to lock due to the pre-operation of the secondary locking mechanism. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a manual maintenance switch that addresses the aforementioned prior art. This manual maintenance switch not only ensures secondary locking but also avoids the problem of one locking mechanism failing to lock due to incorrect sequence operation of the two locking mechanisms.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a manual maintenance switch, comprising:

[0007] First connector;

[0008] The second connector is inserted and mated with the first connector.

[0009] The manual maintenance switch is characterized by comprising:

[0010] The first locking mechanism is configured to drive the first connector and the second connector to switch between an engaged state and a disengaged state.

[0011] The second locking mechanism works in conjunction with the first locking mechanism to form a linked locking mechanism;

[0012] in:

[0013] When the first locking mechanism is in the locked state, the second locking mechanism is configured to switch between the unlocked state and the locked state after a controlled operation; and: when the second locking mechanism switches to the locked state, the first locking mechanism is configured to be forcibly held in the locked state, and the first connector and the second connector maintain an engaged state; when the second locking mechanism switches to the unlocked state, the first locking mechanism is configured to switch between the unlocked state and the locked state after a controlled operation.

[0014] When the first locking mechanism is in the unlocked state, the first and second connectors are configured to switch to a separated state after a controlled operation, and the second locking mechanism is forced to remain in the unlocked state.

[0015] Improved in this invention, the manual maintenance switch includes:

[0016] A lever has a free end and a rotating end, the free end having a sliding groove, and the rotating end being rotatably disposed on the first housing of the first connector; wherein, the rotating end of the lever is further configured to be detachably rotatably disposed on the second housing of the second connector; wherein, the lever forms the first locking mechanism;

[0017] A slider is slidably disposed in a sliding groove at the free end of a lever. The slider has a slider body and a stop portion formed on the slider body. The stop portion is configured to interfere with the free end of the lever to prevent the lever from rotating as the slider slides in a first direction and to release the interference as the slider slides in the opposite direction of the first direction. The slider forms the second locking mechanism.

[0018] Improvedly, the manual maintenance switch further includes a button disposed on the first housing of the first connector; the button is configured to release the engagement between the second connector and the first connector when pressed.

[0019] Improvedly, in the manual maintenance switch, a top contact is provided on the first housing of the first plug body; wherein the top contact is configured to engage with the stop portion of the slider to release the interference.

[0020] In a further improvement, the manual maintenance switch has a first snap-fit ​​structure on the first housing, and the sliding member has a snap-fit ​​structure that snaps into the first snap-fit ​​structure.

[0021] Improvedly, in the manual maintenance switch, the slider has a toggle portion configured to receive external toggle force to produce the back-and-forth sliding.

[0022] In an improved version of the manual maintenance switch, the sliding member has a mating wall located near the first snap-fit ​​structure, and the stop portion is formed on the mating wall.

[0023] Improvedly, in the manual maintenance switch, the first housing of the first connector is provided with a first rotating shaft that rotates with the rotating end of the lever, the second housing of the second connector is provided with a second rotating shaft that rotates with the rotating end of the lever, and the lever is provided with an arc-shaped slide rail that rotates and slides with the second rotating shaft; wherein, the arc-shaped slide rail is configured to move out of the arc-shaped slide rail after the second rotating shaft moves to a preset arc.

[0024] Furthermore, in the manual maintenance switch, the relative rotation angle between the position of the lever when the interference occurs and the position of the lever when it moves out of the arc-shaped slide rail on the second rotation axis is 90 degrees.

[0025] Further improved, in the manual maintenance switch, the first housing of the first plug body is provided with a longitudinal slot that cooperates with the second rotating shaft moving out of the arc-shaped slide rail.

[0026] Furthermore, in the manual maintenance switch, the first rotating shaft is positioned above the second rotating shaft.

[0027] In a further improvement, the manual maintenance switch has a first latching part on the first housing of the first connector and a second latching part on the second housing of the second connector that latches and engages with the first latching part.

[0028] Compared with the prior art, the advantages of this utility model are as follows: In the manual maintenance switch of this utility model, by linking the first locking mechanism and the second locking mechanism to form a manual maintenance switch, it is possible to switch between the unlocked and locked states of the second locking mechanism when the first locking mechanism is in the locked state, and when the second locking mechanism is switched to the locked state, the first locking mechanism is forcibly kept in the locked state and the two plugs remain engaged. Conversely, when the second locking mechanism is switched to the unlocked state, the first locking mechanism can switch between the unlocked and locked states. Furthermore, when the first locking mechanism is in the unlocked state, the two plugs can be switched to the disengaged state and the second locking mechanism is forcibly kept in the unlocked state. Thus, this manual maintenance switch not only controls the locking status of the two plugs but also restricts the locking sequence of the two locking mechanisms, avoiding safety risks caused by incorrect locking operations.

[0039] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0040] This embodiment provides a manual maintenance switch. Specifically, see [link to documentation]. Figures 1-10 As shown, the manual maintenance switch in this embodiment includes a first connector 1, a second connector 2, and a locking mechanism. The first connector 1 and the second connector 2 are plugged into each other to be in an engaged state. The first connector 1 has a first housing 10, and the second connector 2 has a second housing 20. Here, the first connector 1 is a plug, and the second connector 2 is a socket. The locking mechanism includes a first locking mechanism and a second locking mechanism. The first locking mechanism is configured to drive the first connector and the second connector to switch between an engaged state and a disengaged state. The second locking mechanism cooperates with the first locking mechanism to form a linkage locking mechanism.

[0041] in:

[0042] When the first locking mechanism is in the locked state, the second locking mechanism is configured to switch between the unlocked state and the locked state after a controlled operation; and: when the second locking mechanism switches to the locked state, the first locking mechanism is configured to be forcibly held in the locked state, and the first connector and the second connector maintain an engaged state; when the second locking mechanism switches to the unlocked state, the first locking mechanism is configured to switch between the unlocked state and the locked state after a controlled operation.

[0043] When the first locking mechanism is in the unlocked state, the first and second connectors are configured to switch to a separated state after a controlled operation, and the second locking mechanism is forced to remain in the unlocked state.

[0044] More specifically, the manual maintenance switch in this embodiment includes a toggle element 3 and a slider element 4. Wherein:

[0045] The lever 3 has a free end 31 and a rotating end 32. The free end 31 forms a sliding groove 310, and the rotating end 32 is rotatably disposed on the first housing 10 of the first plug body 1. The rotating end 32 of the lever 3 is also configured to be detachably rotatably disposed on the second housing 20 of the second plug body 2, and the lever 3 forms a first locking mechanism.

[0046] The slider 4 is slidably disposed in the sliding groove 310 of the free end 31 of the lever 3. The slider 4 has a slider body 40 and a stop portion 41 formed on the slider body 40. The stop portion 41 is configured to interfere with the free end 31 of the lever 3 as the slider 4 slides in the first direction, preventing the lever from rotating, and to release the interference as the slider 4 slides in the opposite direction in the first direction. The slider 4 forms a second locking mechanism.

[0047] To facilitate smooth sliding of the slider within the sliding groove at the free end of the actuating member, in this embodiment, see... Figure 5 and Figure 6 As shown, a first inclined surface 31a is provided in the sliding groove 310 of the free end 31, and a second inclined surface 40a that cooperates with the first inclined surface 31a is also provided on the slider 4. In this way, the cooperation of these two inclined surfaces can ensure that the slider slides smoothly in the sliding groove of the free end.

[0048] In addition, in this embodiment, the manual maintenance switch also includes a button 5, which is disposed on the first housing 10 of the first plug body 1; the button 5 is configured to release the mutual engagement state between the second plug body 2 and the first plug body 1 when pressed.

[0049] It should be noted that in the manual maintenance switch of this embodiment, by linking the first locking mechanism and the second locking mechanism to form the manual maintenance switch, it is possible to switch between the unlocked and locked states of the second locking mechanism when the first locking mechanism is in the locked state. When the second locking mechanism is switched to the locked state, the first locking mechanism is forcibly kept in the locked state and the two connectors remain engaged. When the second locking mechanism is switched to the unlocked state, the first locking mechanism can switch between the unlocked and locked states. Furthermore, when the first locking mechanism is in the unlocked state, the two connectors can be switched to the disengaged state and the second locking mechanism is forcibly kept in the unlocked state. In this way, the manual maintenance switch not only controls whether the two connectors are locked, but also restricts the locking sequence of the two locking mechanisms, thus avoiding safety risks caused by performing locking operations in the wrong order.

[0050] In order to control the interference of the stop portion of the slider on the actuating member as described above, in this embodiment, see... Figure 1 , Figure 2 and Figure 6 As shown, a top contact portion 10a is provided on the first housing 10 of the first plug body 1; wherein, the top contact portion 10a is configured to cooperate with the stop portion 41 of the top contact slider 4 to release the interference.

[0051] To prevent the sliding element from detaching from the lever element during the secondary locking operation, in the manual maintenance switch of this embodiment, see [reference needed]. Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 9 As shown, the first housing 10 is provided with a first snap-fit ​​structure 11, and the sliding member 4 has a snap-fit ​​structure 42 that snaps into the first snap-fit ​​structure 11.

[0052] In order to facilitate the sliding member to slide back and forth, in this embodiment, the sliding member 4 has a toggle part 43 configured to receive external toggle force to produce the back and forth sliding.

[0053] Specifically, in this embodiment, see Figure 6 As shown, the sliding member 4 has a mating wall 4a located near the first snap-fit ​​structure 11, and a stop portion 41 is formed on the mating wall 4a. The stop portion 41 here is a structure capable of elastic deformation under stress.

[0054] As a mechanism for rotating the lever on both the first and second connectors, and to facilitate the removal of the lever from the second connector, in this embodiment, see [reference needed]. Figures 1-4 As shown, the first housing 10 of the first connector 1 is provided with a first rotating shaft 101 that rotates with the rotating end 32 of the lever 3, and the second housing 20 of the second connector 2 is provided with a second rotating shaft 201 that rotates with the rotating end 32 of the lever 3. The lever 3 is provided with an arc-shaped slide rail 33 that rotates and slides with the second rotating shaft 201; wherein, the arc-shaped slide rail 33 is configured to be movable out after the second rotating shaft 201 rotates to a preset arc. Of course, see correspondingly. Figure 5 As shown, the lever 3 has a lever arm 30 with a rotating end 32 and a free end 31 at its two ends, respectively. The lever arm 30 is provided with a rotating hole 300 for the first rotating shaft 101 of the first connector to be inserted to cooperate with the rotation of the first rotating shaft 101.

[0055] It should be noted that when the second rotating shaft 201 moves within the arc-shaped slide rail 33 that it cooperates with, the first plug-in body 1 and the second plug-in body 2 will correspondingly generate relative movements that move closer or further apart from each other.

[0056] Additionally, preferably, in this embodiment, see Figure 1 , Figure 7 and Figure 10 As shown, the first rotating shaft 101 is positioned above the second rotating shaft 201.

[0057] In this embodiment of the manual maintenance switch, as a preferred arrangement for the second rotating shaft of the second housing to move out of the arc-shaped slide rail, the relative rotation angle between the position of the lever 3 when the interference occurs and the position of the lever 3 when the second rotating shaft 201 moves out of the arc-shaped slide rail 33 is 90 degrees. For example, the position of the lever 3 when the interference occurs is horizontal (i.e., in a plane, perpendicular to the axial direction of the first housing), and correspondingly, the position of the lever 3 when the second rotating shaft 201 moves out of the arc-shaped slide rail 33 is vertical (i.e., in a plane, parallel to the axial direction of the first housing).

[0058] For further optimization, see Figure 3 As shown, in the manual maintenance switch of this embodiment, the first housing 10 of the first plug body 1 is provided with a longitudinal slot 100 that cooperates with the second rotating shaft 201 to move out of the arc-shaped slide rail 33.

[0059] To achieve both the snap-fit ​​assembly and locking between the first and second connectors for a single locking action, and to allow the button to control this locking operation, in this embodiment, see... Figure 1 , Figure 3 and Figure 4 As shown, the first housing 10 of the first connector 1 is provided with a first latching part 1a, and the second housing 20 of the second connector 2 is provided with a second latching part 2a that latches and engages with the first latching part 1a. The first and second latching parts are configured to engage and engage with each other when the button is pressed.

[0060] Although the preferred embodiments of the present invention have been described in detail above, it should be clearly understood that various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
