DETAILED DESCRIPTION

[0020] The core of the present invention is to provide a contactor assembly to facilitate the adjustment of the contactor.

[0021] The following embodiments are described with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the invention contents described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary as solutions to the inventions described in the claims. It should be noted that, for ease of description, only the parts related to the inventions are shown in the accompanying drawings. The embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0022] like Figure 1-Figure 5 As shown, the contactor assembly disclosed in the embodiment of the present invention includes a contactor 1, a fixing plate 4, a connecting plate 3, a first adjustment assembly and a driving assembly.

[0023] Among them, the fixed plate 4 has a first guide rail 5, and the first guide rail 5 has a plurality of first limit slots arranged at intervals. It can be understood by those skilled in the art that the first guide rail 5 is used to provide guidance for the sliding of the connecting plate 3. In order to ensure the stability of the fixed connecting plate 3, a plurality of first guide rails 5 can be provided, such as two disclosed in this embodiment, and the two first guide rails 5 are arranged in parallel. It should be noted that other numbers of first guide rails 5 can be selected according to needs, and are not limited to two. The first guide rail 5 and the fixed plate 4 can be an integrated structure, and can also be fixed to the fixed plate 4 in a corresponding manner.

[0024] There are two connecting plates 3, which are respectively connected to the two sides of the contactor 1. The connecting plates 3 are used to realize the contactor 1 and the fixed plate 4. In other words, the contactor 1 is installed on the fixed plate 4 through the connecting plates 3. The connection method of the connecting plate 3 and the contactor 1 can be a fixed connection method or a movable connection method. The connecting plate 3 has a first positioning groove 12 that slidably cooperates with the first guide rail 5. The first positioning groove 12 can cooperate with the first guide rail 5 to move the connecting plate 3 and the contactor 1 along the extension direction of the first guide rail 5, that is, change the position on the first guide rail 5. In specific use, the first guide rail 5 can extend in the horizontal direction; of course, those skilled in the art can also use the different fixed positions of the fixed plate 4 to extend the first guide rail 5 in other directions.

[0025] The first adjustment assembly is embedded in the connecting plate 3 and includes at least a block 10 that can move between a locking position and an unlocking position. Specifically, a slide groove for the block 10 to move can be provided on the connecting plate 3, and the block 10 reciprocates in the slide groove to switch between the locking position and the unlocking position.

[0026] When the card block 10 is in the locking position, it can cooperate with one of the first limit slots. It can be understood that when the card block 10 is in the locking position, the above-mentioned slide groove is extended in the direction close to the first limit slot so that it can be extended into the first limit slot. After the card block 10 is extended into the first limit slot, the connecting plate 3 cannot continue to move along the first guide rail 5 by utilizing the limiting function of the card block 10 and the first limit slot.

[0027] When the card block 10 is in the unlocked position, it is disengaged from the first limiting slot. It can be understood that when the card block 10 is in the unlocked position, it retracts into the above-mentioned slide groove in the direction away from the first limiting slot so that it can be disengaged from the first limiting slot. After the card block 10 is disengaged from the first limiting slot, the limiting functions of the card block 10 and the first limiting slot are lost, and the connecting plate 3 can continue to move along the first guide rail 5.

[0028] The driving assembly is used to drive the card block 10 to move between the locked position and the unlocked position. Those skilled in the art will appreciate that any method that can drive the card block 10 to move along the slide slot is acceptable, and the embodiment does not limit the driving method of the card block 10 displacement.

[0029] The contactor assembly provided by the present invention can install the contactor 1 on the fixed plate 4, the fixed plate 4 has a first guide rail 5, the connecting plate 3 is fixed on both sides of the contactor 1, the connecting plate 3 has a first positioning groove, and the contactor 1 can be installed on the fixed plate 4 by sliding cooperation between the first positioning groove and the first guide rail 5. The connecting plate 3 is embedded with a first adjustment assembly, and the card block 10 of the first adjustment assembly can move between a locking position and an unlocking position. When the card block 10 is in the locking position, it cooperates with one of the first limiting card slots, so that the connecting plate 3 and the contactor 1 are fixed on the fixed plate 4; when the card block 10 is in the unlocking position, it is disengaged from the first limiting card slot, so that the connecting plate 3 and the contactor 1 can slide along the first guide rail 5 to change the position of the contactor 1. After adjusting to a suitable position, the card block 10 can be matched with the first limiting card slot at the corresponding position. The first adjustment assembly and the drive assembly of the present invention can enable the contactor 1 to be quickly positioned and docked with the fixed plate 4, and after the contactor 1 is installed, its position can also be adjusted to facilitate adaptation to other equipment.

[0030] like Figure 2 and Figure 3 As shown, in a specific embodiment of the present invention, the driving assembly may include a lever 7 and a first elastic member 11, and the first end of the lever 7 is hinged to the contactor 1 through a hinge support, so that the lever 7 can swing along the hinge axis of the hinge support.

[0031] The first adjustment component also includes a push rod 8 and a first connecting rod 9. The second end of the push rod 7 is connected to one end of the push rod 8, and the other end of the push rod 8 is hinged to the first connecting rod 9. The push rod 8 is movably embedded in the connecting plate 3, so that when the first connecting rod 9 is pressed and the first connecting rod 9 swings toward the direction close to the connecting plate 3, the push rod 7 can push the push rod 8 to move.

[0032] The first connecting rod 9 is hinged to the block 10, and the moving direction of the push rod 8 is perpendicular to the moving direction of the block 10. When the lever 7 pushes the push rod 8 to move, it will push the first connecting rod 9 to move in space. It should be noted that a hollow structure needs to be provided on the connecting plate 3 according to the movement range of the first connecting rod 9 to prevent the connecting plate 3 from hindering the movement of the first connecting rod 9. When the first connecting rod 9 is pushed, the block 10 can be pulled away from the first guide rail 5, and at the same time, the first elastic member 11 is compressed to store energy, so that the block 10 moves to the unlocking position and disengages from the first limit slot.

[0033] One end of the first elastic member 11 is connected to the card block 10, and the other end is connected to the connecting plate 3, so as to push the card block 10 into the first limit card slot. That is, when the first connecting rod 9 is not pressed, the card block 10 is pushed to return to the locking position under the action of the spring force of the first elastic member 11, that is, inserted into the first limit card slot.

[0034] The second end of the lever 7 is connected to one end of the push rod 8. This connection does not refer to a fixed connection. As long as the second end of the lever 7 can transmit the thrust to the push rod 8, so as to pull the first connecting rod 9 and the block 10 through the push rod 8, the second end of the lever 7 abuts against the end of the push rod 8, the above function can also be achieved.

[0035] Furthermore, the first guide rails 5 are two arranged in parallel, and the first limit slots of the two first guide rails 5 are arranged opposite to each other. Each first guide rail 5 is correspondingly provided with a card block 10, and each card block 10 is correspondingly provided with a first connecting rod 9. The push rod 8 is hinged to the two first connecting rods 9 through a hinge seat, and the end of the push rod 8 is fixed with a hinge seat, and the two first connecting rods 9 are symmetrically hinged to the hinge seat. That is, when the push rod 7 pushes the push rod 8 to move, the push rod 8 drives the hinge seat to move. Since the ends of the two first connecting rods 9 are hinged on the hinge seat, the two first connecting rods 9 are pushed to tilt, and then the card block 10 is pulled out of the first limit slot. In this embodiment, the use of a push rod 7 and a push rod 8 can realize the synchronous action of the two card blocks 10.

[0036] In order to enable the lever 7 to apply thrust stably to the push rod 8, the portion where the lever 7 is connected to the push rod 8 may be designed as a plate-like structure to increase the coverage area, thereby avoiding the risk that the lever 7 cannot apply force to the push rod 8.

[0037] In order to enable the contactor 1 to be positionally adjustable both laterally and longitudinally, in this embodiment, the connecting plate 3 is connected to the contactor 1 via a second adjusting component 13 , so that the position of the contactor 1 relative to the connecting plate 3 can also be adjusted.

[0038] The connecting plate 3 is provided with a plurality of second limit slots 31 arranged at intervals, and the arrangement direction of each second limit slot 31 is perpendicular to the extension direction of the first guide rail 5. For example, if the lateral position of the contactor 1 can be adjusted along the direction of the first guide rail 5, the longitudinal position of the contactor 1 can be adjusted along the arrangement direction of the second limit slots 31.

[0039] Please combine Figure 7 In this embodiment, the second adjustment component 13 includes a connecting block 131 and a clamping rod 133. The connecting block 131 is fixed to the contactor 1, and the clamping rod 133 is slidably matched with the connecting block 131, and the clamping rod 133 can slide between a locked position and an unlocked position. Specifically, a sliding groove for the clamping rod 133 to slide and match can be provided.

[0040] When the card rod 133 is in the locking position, it cooperates with one of the second limit slots 31. It can be understood that when the card rod 133 is in the locking position, the above-mentioned slide groove is extended in the direction close to the second limit slot 31, so that it can be extended into the second limit slot 31. After the card rod 133 is extended into the second limit slot 31, the connecting plate 3 and the contactor 1 cannot continue to move by utilizing the limiting function of the card rod 133 and the second limit slot 31.

[0041] When the card rod 133 is in the unlocked position, it is disengaged from the second limit slot 31. It can be understood that when the card rod 133 is in the unlocked position, the above-mentioned slide groove is retracted in the direction away from the second limit slot 31 so that it can be disengaged from the second limit slot 31. After the card rod 133 is disengaged from the second limit slot 31, the limiting function of the card rod 133 and the second limit slot 31 cannot be utilized, and the connecting plate 3 and the contactor 1 can move relative to each other.

[0042] Furthermore, the second adjustment assembly 13 also includes a second elastic member 132, one end of the second elastic member 132 abuts against the connection block 131, and the other end abuts against the clamping rod 133, so as to push the clamping rod 133 to the locking position of the clamping rod 133. The second elastic member 132 can keep the clamping rod 133 in the locking position, and when it is necessary to move the clamping rod 133 to the unlocking position, it is necessary to compress the second elastic member 132 to store energy. After the force for moving the clamping rod 133 is removed, the second elastic member 132 pushes the clamping rod 133 to reset to be inserted into the second limit slot 31, so that during the normal use of the contactor assembly, the connecting plate 3 and the contactor 1 can remain in a fixed state.

[0043] Furthermore, the second adjustment assembly 13 may also include a toggle rod 134 hinged on the connection block 131, the card rod 133 is provided with a strip groove 135, one end of the toggle rod 134 abuts against the toggle rod 7, and the other end extends into the strip groove 135 to toggle the card rod 133. In this embodiment, the force for the card rod 133 to move to the locking position is provided by the second elastic member 132, and the force for the card rod 133 to move to the unlocking position is provided by the toggle rod 7. That is, in this embodiment, whether it is longitudinal unlocking or transverse unlocking, it is necessary to drive the toggle rod 7 to swing, that is, the user's participation is required, and whether it is longitudinal locking or transverse locking, the user's participation is not required, and the corresponding elastic member can keep the corresponding card block 10 and the card rod 133 in the locking position.

[0044] When the lever 7 pushes the push rod 8 to move, the lever 134 is simultaneously pushed to swing, so as to drive the clamping rod 133 to move to the unlocking position of the clamping rod 133. In this embodiment, the clamping rod 133 and the push rod 8 can be driven to move simultaneously by one lever 7, that is, the horizontal unlocking and the vertical unlocking are completed, and the operator can adjust the horizontal and vertical positions of the contactor 1 at the same time.

[0045] In a specific embodiment of the present invention, second guide rails 6 are provided on both sides of the contactor 1, and the extension direction of the second guide rails 6 is perpendicular to the extension direction of the first guide rails 5, that is, the arrangement direction of the second guide rails 6 and the second limiting slots 31 are parallel. The connecting plate 3 is provided with a second positioning groove that is slidably matched with the second guide rails 6. Through the cooperation between the second guide rails 6 and the second positioning grooves, the connecting plate 3 can be limited in other directions except the extension direction of the second guide rails 6.

[0046] To sum up, the contactor assembly disclosed in the embodiment of the present invention, when positioned and docked with the fixed plate 4, the positioning grooves 12 of the connecting plates 3 on both sides of the contactor 1 are docked with the first guide rails 5 on one side of the fixed plate 4. The ends of the first guide rails 5 can be chamfered, and the corresponding opening sides of the positioning grooves 12 can also be chamfered to assist in positioning, making the docking of the two more convenient.

[0047] An inclined surface may also be provided at the end of the card block 10 to facilitate insertion into the first limit slot of the first guide rail 5. After the first guide rail 5 is inserted into the positioning slot 12, when the inclined surface of the card block 10 inside the connecting plate 3 contacts the first guide rail 5, the card block 10 will move and squeeze the first elastic member 11. When the card block 10 contacts the first limit slot of the first guide rail 5, the first elastic member 11 will reset, pushing the card block 10 to engage with the first guide rail 5, thereby completing the installation of the contactor.

[0048] When the lateral and longitudinal positions of the contactor need to be adjusted, the levers 7 on both sides of the contactor 1 are swung, and the levers 7 will push the push rods 8 and the swivel rods 134 to move together. When the push rods 8 move, they can push the two sets of first connecting rods 9 at one end to rotate. When the two sets of first connecting rods 9 rotate, they can pull the card block 10 to move so that it is out of engagement with the first limit card slot. At this time, the contactor 1 can be moved horizontally, driving the connecting plate 3 to slide along the first guide rail 5 to change its position. At the same time, the toggle rod 134 pushed by the first connecting rod 9 will also rotate, causing the second adjusting component 13 to start moving. The toggle rod 134 will slide in the strip groove 135 inside the clamping rod 133, thereby toggling the clamping rod 133 to move and squeezing the second elastic member 132 to shrink it. When the clamping rod 133 is disengaged from the second limiting clamping groove 31 in the connecting plate 3, the contactor 1 can be longitudinally moved on the inner side of the connecting plate 3, so that the longitudinal position of the connecting plate 3 can be adjusted.

[0049] When the lateral and longitudinal positions of the contactor 1 are adjusted, the lever 7 can be released. At this time, the second elastic member 132 and the first elastic member 11 will be reset, so that the clamping rod 133 is engaged with the connecting plate 3, and the clamping block 10 is engaged with the first guide rail 5, and the contactor 1 is fixed. In this way, the contactor 1 and the fixing plate 4 can be quickly positioned and docked through the above operations. At the same time, after the installation of the contactor 1 is completed, its position can be adjusted to facilitate its adaptation to other equipment.

[0050] like Figure 2 As shown, in a specific embodiment of the present invention, heat dissipation areas for heat dissipation are provided on both sides of the contactor 1. In order to prevent dust from entering the contactor 1 through the openings of the heat dissipation areas and affecting the electrical performance, a dustproof net 14 is usually fixedly connected to the heat dissipation area. The dustproof net 14 will not affect the heat dissipation of the heat dissipation area and can prevent impurities such as dust from entering the contactor 1.

[0051] As the usage time increases, the dust screen 14 will be contaminated with many impurities, which will block the heat dissipation holes of the dust screen 14 and affect the heat dissipation of the contactor 1. Based on this, the contactor assembly disclosed in this embodiment also includes a cleaning device disposed on the contactor 1 for cleaning the dust screen 14.

[0052] In this embodiment, the cleaning device includes a slide bar 15 and a cleaning brush 17. Two slide bars 15 are provided for each dustproof net 14, and the two slide bars 15 are respectively arranged on both sides of the dustproof net 14. A cleaning brush 17 is provided for each dustproof net 14, and the cleaning brush 17 is slidably matched with the two slide bars 15 corresponding to the dustproof net 14. The slide bar 15 is used to install the cleaning brush 17, and the cleaning brush 17 can also slide along the slide bar 15 to move from one end of the dustproof net 14 to the other end.

[0053] The cleaning brush 17 is in contact with the dustproof net 14. When the cleaning brush 17 moves along the sliding rod 15, the brush head of the cleaning brush 17 is in contact with the dustproof net 14, and the dustproof net 14 is cleaned from one end to the other end. This is repeated several times to remove impurities attached to the dustproof net 14 and restore the heat dissipation effect of the dustproof net 14.

[0054] A limit seat is provided on the contactor 1 , and both ends of the slide bar 15 are respectively set on the limit seat. The limit seat can limit the movement of the cleaning brush 17 . In addition to providing a mounting base for the slide bar 15 , it can also limit the movement range of the cleaning brush 17 .

[0055] Furthermore, the cleaning device may further include a third elastic member 16 and a second connecting rod 18. The third elastic member 16 is sleeved on the slide bar 15 and is used to push the cleaning brush 17 to one end of the slide bar 15. One end of the third elastic member 16 abuts against the limit seat, and the other end abuts against the cleaning brush 17, and then the cleaning brush 17 can be pushed to a corresponding position, so that the cleaning brush 17 abuts against another limit seat.

[0056] The dust-proof nets 14 on the same side of the contactor 1 are arranged in pairs, and there are two second connecting rods 18. One end of the two second connecting rods 18 is hinged to the push block 19, and the other ends of the two second connecting rods 18 are respectively hinged to the cleaning brushes 17 corresponding to the two dust-proof nets 14. It should be noted that for the two dust-proof nets 14, the third elastic members 16 corresponding to the two dust-proof nets 14 push their respective cleaning brushes 17 to a position close to each other. Pressing the push block 19 can open the two second connecting rods 18, push the two cleaning brushes 17 away from each other, and clean the corresponding dust-proof nets 14. When the push block 19 is released, the third elastic member 16 resets and pushes the respective cleaning brushes 17 to the initial position. In summary, the cleaning of the dust-proof net 14 can be completed by repeatedly pressing the push block 19.

[0057] To sum up, in order to prevent the dust net 14 from accumulating dust after long-term use, the push block 19 is pushed to move, and the push block 19 will push the two second connecting rods 18 to rotate and unfold. When the second connecting rods 18 are unfolded, they can push the two sets of cleaning brushes 17 to slide along the sliding rod 15 and squeeze the third elastic member 16 sleeved on the sliding rod 15.

[0058] When the push block 19 cannot be pushed further, the push block 19 can be released. At this time, the third elastic member 16 will be reset and push the cleaning brush 17 to reset as well. By repeatedly pushing the push block 19, the two groups of cleaning brushes 17 can be reciprocated on the outsides of the two groups of dustproof nets 14, thereby cleaning the dust on the outsides of the dustproof nets 14, keeping the dustproof nets 14 unobstructed, ensuring the heat dissipation of the internal components of the contactor 1, and allowing the internal airflow of the contactor 1 to be quickly exchanged with the external airflow.

[0059] like Figure 6 As shown, in a specific embodiment of the present invention, the contactor 1 has a plurality of wiring slots, and the wiring terminals 2 are arranged in the wiring slots. The exposed parts of the wiring harness can be inserted into the wiring terminals 2 through the openings of the wiring slots to maintain electrical connection.

[0060] In this embodiment, at least at the opening of the wiring slot at the top of the contactor 1, a baffle 20 is hinged by a rotating shaft, and the side wall of the wiring slot is provided with a spring sheet 21, which abuts against the lower side of the baffle 20 to support the baffle 20 in a position to close the opening of the wiring slot. That is, under the action of the spring sheet 21, the baffle 20 is kept in a position to close the opening of the wiring slot, so that dust can be prevented from falling into the wiring terminal 2 through the opening of the wiring slot when no wiring is connected.

[0061] Each wiring slot is provided with two baffles 20, which are opened and closed in the manner of double doors, that is, the adjacent ends of the two baffles 20 can be pressed down to rotate the baffles 20 to open, so that the wiring harness can be inserted through the opening of the wiring slot to complete the wiring.

[0062] The butt joint of the two baffles 20 is an arc-shaped end that bends downward. That is, the ends of the two baffles 20 that are close to each other are designed to be arc-shaped ends that bend downward, so that when the wire harness is inserted, the arc-shaped end has a guiding effect on the wire harness, and the wire harness can automatically slide into the gap between the two baffles 20, and rely on the thrust of the wire harness to open the two baffles 20. A storage groove 22 is provided on the side wall of the wiring slot for the arc-shaped end of the baffle 20 to be embedded after it is opened, so as to prevent the baffle 20 from affecting the wire harness.

[0063] To summarize, in order to provide dust protection for the unplugged terminal 2 at the top of the contactor 1, two sets of baffles 20 are set on the top of the terminal 2. The two sets of baffles 20 will shield the terminal 2 to prevent the entry of dust. When the wiring harness is inserted into the terminal 2, it will first contact the baffle 20. At this time, the baffle 20 will rotate and unfold, and squeeze the spring piece 21 on one side. When the wiring harness is fully inserted into the terminal 2, the arc-shaped end of one end of the baffle 20 will enter the storage groove 22 to complete the folding and storage.

[0064] When the wire harness needs to be taken out, the wire harness can be pulled away from the terminal 2. Since one end of the baffle 20 is an arc surface and the end is in the storage groove 22, it will not come into contact with the raised part at the end of the wire harness, which can prevent the baffle 20 from rotating when the wire harness moves up, causing the two sets of baffles 20 to be closed before the wire harness completely leaves the terminal 2, affecting the removal of the wire harness. When the wire harness completely leaves the terminal 2, the spring 21 will reset and push the two sets of baffles 20 to close the top of the terminal 2 to prevent dust from entering. In this way, the terminal 2 at the top of the contactor 1 can be dust-proofed through the above operation.
