As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The invention provides an elevator control box and a cable leading-out connector thereof.

Referring to fig. 1 and 2 together, an elevator control box 10 according to a preferred embodiment of the present invention includes a housing 200, a cable 300, and a cable outlet connector 100.

The housing 200 has a hollow structure. The housing 200 protects elevator components housed in the housing 200. The cabinet 200 has a wall 210 with a hole 220. The cable 300 is inserted into the outlet hole 220 and led out from the outlet hole 220 to electrically connect the components in the housing 200 with external elements, thereby controlling the elevator. The cable outlet connector 100 is used to fix the cable 300 to the cabinet 200, so as to prevent the cable 300 from being separated from a plug or a circuit board in the cabinet 200 by an external pulling force, which may cause an elevator malfunction.

Referring to fig. 3, 4 and 5, the cable outlet connector 100 of the preferred embodiment of the present invention includes a body 110 and a retaining member 120.

The body 110 has a lead passage 111 with openings 112 at both ends, and a through hole 113 communicating with the lead passage 111 is opened at a side wall of the lead passage 111. The body 110 is used to support components of the cable outlet connector 100. In the elevator control box 10, the body 110 is fixed to the wall 210 of the cage 200, the lead hole 220 corresponds to the lead passage 111, and the cable 300 is inserted into the lead hole 220 and the lead passage 111 to be led out of the cage 200. Specifically, the body 110 may have a rectangular, polygonal, or other configuration, as long as the cable 300 can pass through the body 110. In the embodiment, the body 110 is rectangular, so that the sidewalls of the body 110 are planar, thereby facilitating the arrangement of the elements of the cable outlet connector 100 on the sidewalls of the body 110. In addition, by providing the body 110 in a rectangular shape, a linear-shaped lead passage 111 can be formed. Therefore, when the cable 300 is inserted into the lead passage 111 from the opening 112 of the body 110, the inner wall of the lead passage 111 has a small blocking effect on the cable 300, thereby facilitating the installation of the cable 300.

The retainer 120 is disposed through the through hole 113. The end of the retainer 120 located in the wire guiding channel 111 has a retainer 121, and the retainer 121 is engaged with the inner wall of the wire guiding channel 111 to form the cable bayonet 114 in the wire guiding channel 111.

Wherein the catch 120 is operable to slide in a direction perpendicular to the axis of the wire channel 111 to adjust the size of the cable bayonet 114.

When the cable 300 is inserted into the lead-in channel 111, the size of the cable bayonet 114 is matched with the size of the cable 300, so that the cable 300 can be clamped in the lead-in channel 111. When the number of cables 300 is changed, the size of the cable catch 114 can be adjusted by operating the catch 120 to slide in a direction perpendicular to the axis of the wire guide channel 111, and the size of the cable catch 114 can be matched with the size of different numbers of cables 300. Therefore, the elevator control box 10 and the cable outlet connector 100 thereof can control the size of the cable mount 114 by operating the sliding of the holding member 120 to fix different numbers of cables 300 on the machine case 200, so that the cable outlet connector 100 has better reliability and wide applicability.

It should be noted that the catch 120 is operable to slide in a direction perpendicular to the axis of the wire passage 111, which means that the catch 120 is slidable when the operator operates the catch 120. When the operator does not operate the catching member 120, the sliding of the catching portion 121 is stopped, and at this time, the portion of the catching member 120 extending into the wire guiding passage 111 can be fixed to the inner wall of the wire guiding passage 111 to clamp the cable 300.

In the present embodiment, the inner wall of the wire passage 111 and the side wall of the catch 120 cooperate with the ratchet 131 via the pawl 132, so that the catch 120 is operable to slide in a direction perpendicular to the axis of the wire passage 111.

Pawl 132 is in one-way engagement with ratchet bar 131. In the present embodiment, when the size of the cable bayonet 114 needs to be reduced, the operation catch 120 slides in a direction away from the through-hole 113, so that the size of the cable bayonet 114 is reduced. The operation is stopped, the catch 120 stops sliding, and the cable mount 114 is fixed in size. When the size of the cable bayonet 114 needs to be increased, the pawl 132 can be separated from the ratchet 131 by an external tool, and the holding member 120 is operated to slide in a direction toward the through hole 113, so that the size of the cable bayonet 114 can be increased. Therefore, the engagement of the pawl 132 with the ratchet 131 between the inner wall of the wire guide channel 111 and the side wall of the catch 120 allows the cable outlet connector 100 to hold a different number of cables 300, thereby achieving a wide applicability of the cable outlet connector 100. Specifically, the pawl 132 may be provided as any one of an inner wall of the wire passage 111 or a side wall of the catch 120, and the ratchet 131 is provided as the other one of the inner wall of the wire passage 111 or the side wall of the catch 120 to achieve the engagement of the ratchet 131 with the pawl 132.

Moreover, in order to achieve a better fixing effect, the pawl 132 is disposed on either side of the wire channel 111 or both sides of the retaining member 120, and the ratchet 131 is disposed on the other side of the wire channel 111 or both sides of the retaining member 120, so that the ratchet 131 and the pawl 132 can fix the retaining member 120 from both sides of the retaining member 120, so as to prevent the cable 300 from being loosened during the process of retaining the cable 120 and affecting the operation of the cable control box 10.

It should be noted that, in other embodiments, suction members may be disposed on both the inner wall of the wire guiding channel 111 and the side wall of the retaining member 120, and the retaining member 120 may slide operatively through the suction effect between the suction members. Or, a through hole may be formed in the inner wall of the lead channel 111, and when the size of the cable mount 114 matches the number of the cables 300, a screw may be inserted into the through hole from the outside of the body 110, and the screw may be abutted against the retaining member 120, so that the retaining member 120 may slide operatively.

Referring to fig. 6 and 7, in the present embodiment, a dust-proof portion 122 is formed at an end of the holding member 120 away from the holding portion 121, and the dust-proof portion 122 is in clearance fit with the through hole 113.

The dust-proof portion 122 is in clearance fit with the through hole 113, and functions to cover the through hole 113. When the retainer 120 stops moving, the dust-proof block 122 can cover the through hole 113, so as to prevent external dust, debris and the like from entering the case 200 through the lead channel 111.

Specifically, the dust-proof portion 122 may be a block structure connected in one piece, or may be a plurality of block structures arranged at intervals, specifically, in the present embodiment, the dust-proof portion 122 includes a plurality of dust-proof blocks 1222, the plurality of dust-proof blocks 1222 are arranged at intervals in a direction perpendicular to the axis of the lead channel 111, and each dust-proof block 1222 is in clearance fit with the through hole 113.

Specifically, the dust block 1222 and the through hole 113 should have the same shape, but the size is slightly smaller than the through hole 113. When the retainer 120 slides, it is ensured that the dust-proof block 1222 can enter the lead passage 111 through the through hole 113, so as to prevent the dust-proof block 1222 from being caught by the through hole 113 and interfering with the sliding of the retainer 120. Different sizes of the cable mount 114 correspond to different dust-proof blocks 1222, and when the size of the cable mount 114 changes, the corresponding dust-proof block 1222 is matched with the through hole 113.

By providing a plurality of dust-proof blocks 1222 and spacing the dust-proof blocks 1222, the material usage of the chucking member 120 can be reduced, thereby facilitating the reduction of the weight of the chucking member 120 and allowing the movement of the chucking member 120 to have better flexibility.

Specifically, two connecting rods may be provided to connect both ends of the plurality of dust blocks 1222 to connect the plurality of dust blocks 1222 as a whole. Two connecting rods are respectively disposed at opposite ends of each dust-proof block 1222. In this embodiment, the cable outlet connector 100 further includes an elongated substrate 123, and a plurality of dust-proof blocks 1222 are fixed on the surface of the substrate 123 to implement connection. By providing the substrate 123, the connection of the dust-proof blocks 1222 is more secure.

Each dust block 1222 protrudes from opposite side surfaces of the base plate 123 and is axisymmetrical with respect to the base plate 123, so that the balance stability of the chucking member 120 can be further maintained.

Further, in the present embodiment, a break point 124 is further provided between two adjacent dust-proof blocks 1222.

When the retainer 120 moves to a certain position and stops, one of the dust-proof blocks 1222 is inserted through the through hole 113. In order to prevent the other dust-proof blocks 1222 protruding from the wire passage 111 from affecting the aesthetic appearance of the elevator control box 10, the other dust-proof blocks 1222 located above the through-holes 113 may be partially broken off and removed from the breaking points 124. Therefore, by providing the breaking point 124, the operator can easily remove the redundant dust-proof block 1222, thereby improving the convenience of operation.

Specifically, in the present embodiment, the breaking point 124 is a through slot opened on the substrate 123, and the through slot is located at a connection position of the dust-proof block 1222 and the substrate 123.

Typically the connection is a stress concentration location. By providing through slots at the junctions of the base plate 123, removal of the excess dust block 1222 is more labor-efficient.

In this embodiment, one end of the retaining member 120 located in the lead channel 111 is in an inverted U-shaped structure, the U-shaped structure includes a bottom edge 1212 and two bracket edges 1211, the two bracket edges 1211 are respectively and vertically connected to two ends of the bottom edge 1212, the dust-proof block 122 is in a strip shape, and the bottom edge 1212 and the dust-proof block 122 are arranged in parallel and have the same length.

Specifically, the width of the substrate 123 is also kept consistent with the length of the dust-proof block 122. Accordingly, the entire catch 120 is made axisymmetric about the center line of the catch 120, thereby facilitating maintenance of stability during movement of the catch 120. In addition, the two bracket edges 1211 are vertically connected to two ends of the bottom edge 1212, respectively, the dust-proof block 122 is in a strip shape, and the bottom edge 1212 and the dust-proof block 122 are parallel and have the same length, which means that the U-shaped structure can also realize clearance fit with the through hole 113, so that the whole clamping member 120 can be inserted into or pulled out of the lead channel 111, thereby facilitating the installation of the clamping member 120.

In the present embodiment, through holes 113 are respectively formed in two opposite sidewalls of the body 110, and the two through holes 113 correspond to each other in position. Specifically, the through hole 113 may include a first through hole and a second through hole. The gap of the U-shaped structure faces the second through hole 113. The bracket edge 1211 of the U-shaped structure may be inserted into the second through hole. Specifically, when the two support sides 1211 are completely received in the wire passage 111, the catch 121 is referred to as an entire U-shaped structure. When the two support edges 1211 are disposed through the second through hole and partially extend out of the second through hole, the retaining portion 121 refers to the bottom edge 1212 and the portion of the two support edges 1211 that are received in the lead channel 111.

Also, in order to make the movement of the catch 120 more flexible and simple, the height of the leg edge 1211 is set to be greater than the height of the body 110 in a direction perpendicular to the wire passage 111. The pawls 132 are disposed on opposite sides of the wire guiding channel 111, and the two support edges 1211 are provided with the ratchets 131, so that the cable clamping opening 114 can be stably fixed on the body 110 after being sized, and the retaining member 120 can be stably fixed on the body 110.

In the operation process, the frame sides 1211 are all inserted through the second through holes 113 and extend out of the lead channel 111. When the size of the cable mount 114 needs to be reduced, the bracket 1211 can be pulled from below to drive the catch 120 to move in a direction away from the first through hole. When the size of the cable bayonet 114 needs to be increased, the two support edges 1211 can be tightly held from below, so that the two support edges 1211 are close to each other, and the pawl 132 is separated from the ratchet strip 131. At this time, the bracket edge 1211 is pushed upward, so that the catch 120 can be driven to move in a direction toward the first through hole, so as to adjust the size of the cable bayonet 114. After the cable bayonet 114 is adjusted in size, a portion of the bracket edge 1211 protruding out of the lead channel 111 can be cut off to maintain the aesthetic appearance of the cable outlet connector 100.

Referring to fig. 8 and 9, the cable outlet connector 100 further includes a fixing member 140. The fixing member 140 includes a limiting plate 141, and the fixing member 140 cooperates with the body 110 to form an engaging portion 143 between the limiting plate 141 and the body 110 for engaging with the tank wall 210. The fixing member 140 is operable to slide along the axis of the wire passage 111 to adjust the size of the engaging portion 143.

Since different elevator control boxes 10 have different wall thicknesses. In the elevator control box 10, the wall 210 of the cage 200 is disposed between the fixing member 140 and the body 110. The fixing member 140 is operable to slide along the axis of the wire guiding channel 111, and the size of the engaging portion 143 can be increased or decreased to match the size of the engaging portion 143 with the wall thickness, thereby facilitating the stable fixing of the body 110 to the tank wall 210.

In this embodiment, the middle portion of the limiting plate 141 is further opened with a through hole aligned with the lead-out hole 220, so that the cable 300 can be led out of the machine case 200 through the through hole, the lead-out hole 220 and the lead passage 111 in the elevator control box 10.

Further, in the embodiment, the fixing member 140 further includes two insertion plates 142 disposed on the limiting plate 141, the two insertion plates 142 are disposed on the limiting plate 141 in parallel and at intervals, a slot 116 is formed at a position of the sidewall of the main body 110 opposite to the insertion plate 142, and the insertion plate 142 is clamped in the slot 116.

By retaining the insert plate 142 in the slot 116, the body 110 can be more stably fixed to the tank wall 210. Specifically, the slots 116 are through slots and are formed on two opposite side walls of the body 110, and the two insertion plates 142 are respectively in one-to-one correspondence with the two slots 116, so that the body 110 can be stably fixed on the tank wall 210.

Furthermore, in order to achieve the best motion stability, the height of the insert plate 142 in the direction perpendicular to the wire passage 111 should be consistent with the height of the body 110, so that the wire fixing member 140 has the largest contact area with the body 110, and thus the body 110 can be stably fixed to the tank wall 210.

Further, in this embodiment, the groove wall of the slot 116 and the surface of the insert plate 142 are engaged with the ratchet 131 via the pawl 132, so that the fixing member 140 can slide along the axis of the wire passage 111.

Pawl 132 is in one-way engagement with ratchet bar 131. In the present embodiment, when the size of the engaging portion 143 needs to be reduced, the operating body 110 is slid in the direction toward the stopper plate 141, so that the size of the engaging portion 143 is reduced. The operation is stopped, the holding member 120 stops sliding, and the size of the engaging portion 143 is fixed and matched with the thickness of the tank wall 210. When the size of the engaging portion 143 needs to be increased, the external tool can separate the pawl 132 from the ratchet 131, and the operation body 110 slides in a direction away from the limiting plate 141, so that the size of the engaging portion 143 can be increased. Therefore, the engagement of the ratchet 132 with the ratchet 131 at the groove wall of the insertion groove 116 and the surface of the insertion plate 142 allows the cable outlet connector 100 to be mounted on elevator control boxes 10 having different wall thicknesses, thereby achieving a wide applicability of the cable outlet connector 100.

The elevator control box 10 and the cable outlet connector 100 thereof can lead the cable 300 out of the box 200 through the outlet hole 220 and the lead channel 111. The holding portion 121 is engaged with the inner wall of the wire guiding channel 111 to form a cable bayonet 114 in the wire guiding channel 111, and the cable 300 is inserted through and held in the cable bayonet 114 to fix the case 200. When the number of cables 300 is changed, the catch 120 is operable to slide along a direction perpendicular to the axis of the wire guide channel 111 to adjust the size of the cable mount 114 and match the size of the changed number of cables 300. Therefore, the elevator control box 10 and the cable leading-out connector 100 thereof can fix different numbers of cables 300 on the machine case 200 by controlling the size of the cable bayonet 114, thereby having better reliability.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
