Specifically, in the present embodiment, the wiring device 100 is used to wire the test instrument and the device under test, so that one end of the first wire 140 is used to electrically connect with the device under test and the other end is used to connect with the test instrument. The device under test is for example a circuit breaker. The test instrument is, for example, a circuit breaker mechanical characteristic tester.
The first lead 140 is wound around the reel 130. One end of the first wire 140 can protrude from an outlet (not shown) of the junction box 120 out of the junction box 120 and out of the junction box 110, and thus can be used for connection with a device under test or a test instrument outside the junction box 110. Similarly, the other end of the first wire 140 may be connected to a device under test or a test instrument outside the junction box 110.
It is understood that the wiring device 100 can be used for wiring between other different electric devices, and is not limited to a testing instrument and a tested device.
The control device may be a PLC controller, a microprocessor, or the like.
When the wiring of the test instrument and the tested equipment is needed, the driving assembly can be controlled to be in the second state through the control device, and in the second state, the driving assembly releases the reel 130, so that the reel 130 can rotate freely, therefore, a worker can drive the reel 130 to rotate by pulling the first lead 140, and the first lead 140 can be gradually released from the reel 130, so that the reel 130 can be passively paid off, and the wiring of the test instrument and the tested equipment is further facilitated.

In the wiring device 100, when the control device controls the driving assembly to be in the second state, the driving assembly releases the reel 130, and the first lead 140 can be pulled to drive the reel 130 to rotate, so that the first lead 140 can be paid off from the reel 130, and further, two different electric devices can be conveniently wired through the first lead 140. When the wiring is not needed, the control device can control the driving assembly to be switched to the first state, and the driving assembly can drive the reel 130 to rotate, so that the first lead wire 140 is stored in the reel 130. Therefore, the wiring device 100 is convenient to take up and pay off the wires, and the first wires 140 are wound on the reels 130, the reels 130 are stored in the junction box 120, and the junction box 120 is stored in the junction box 110, so that the first wires 140 can be kept orderly all the time in the process of taking up and paying off the wires.
Referring to fig. 1 to 2, the number of the cluster blocks 120 is plural, and the cluster blocks 120, the reels 130, and the driving units correspond one to one. The plurality of cluster blocks 120 are provided independently of each other.
Specifically, a plurality of first conductive lines 140 may be used according to the test requirements of the test instrument and the device under test. Therefore, a plurality of first conductive lines 140 may be provided for the wiring device 100. For example, in the present embodiment, the number of the first conductive lines 140 is four. Since the cluster blocks 120, the reels 130, and the driving units correspond one to one, even if the number of the first wires 140 is large, the lines can be kept orderly and conveniently drawn and paid out.
Since the plurality of cluster blocks 120 are provided independently of each other, it is convenient to use an arbitrary number of cluster blocks 120 individually as needed.
Referring to fig. 1 and 2, in an embodiment, the junction box 110 is provided with an outlet notch 101, and one end of the first wire 140 can extend out of the junction box 110 from the outlet notch 101. The junction box 110 is further provided with a junction port 102, and a conductor (not shown) is provided at the junction port 102 and electrically connected to the other end of the first wire 140.

The first panel 113 is for covering and shielding the cluster block 120, and the first panel 113 is provided inside the case 111. The outlet slot 101 is provided in the first panel 113. One end of the first wire 140 protrudes from the outlet slot 101 to the outside of the junction box 110, thereby facilitating connection with the device under test. It is understood that the outlet slot 101 may be provided in the case 111 or the cover 112.
As shown in fig. 2, in the present embodiment, the junction box 110 further includes a second panel 114. The second panel 114 is disposed in the box 111. The connection port 102 is provided in the second panel 114. A conductor may be provided in the wire connection port 102 and then electrically connected to the other end of the first wire 140 by soldering or the like. When the test instrument is electrically connected to the other end of the first wire 140, a connection wire is additionally disposed to electrically connect to the test instrument, and then one end of the connection wire is inserted into the connection port 102, so that the connection wire can be electrically connected to the other end of the first wire 140 through the conductor, and the test instrument is electrically connected to the other end of the first wire 140. It can be seen that by providing the wire connection port 102 and the conductor, it is convenient to electrically connect the test instrument to the other end of the first wire 140.
As can be seen from the above analysis, the testing instrument can be electrically connected to the other end of the first wire 140 only by inserting an additional connecting wire into the wire connection port 102, which is convenient in connection. And the end of the first wire 140 extending out of the box 111 can be pulled to the tested device to be electrically connected with the tested device.
Referring to fig. 3, in an embodiment, the driving assembly includes a motor 151 and an electromagnetic clutch 152 connected to the motor 151.

Specifically, in the present embodiment, the drive assembly further includes a speed reduction mechanism 153 driven by the motor 151, and the electromagnetic clutch 152 is connected to an output shaft of the speed reduction mechanism 153. The speed reduction mechanism 153 may be a gear reducer, and the speed reduction mechanism 153 may reduce the rotation speed and increase the torque.
When the driving assembly is in the first state, the control device controls the electromagnetic clutch 152 to pull in the reel 130. The rotation of the motor 151 rotates the speed reduction mechanism 153, so that the speed reduction mechanism 153 rotates the electromagnetic clutch 152, and the electromagnetic clutch 152 rotates the reel 130.
When the driving assembly is in the second state, the control device controls the electromagnetic clutch 152 to release the reel 130, so that the reel 130 can rotate around the axis thereof.
The specific structure and the attracting principle of the electromagnetic clutch 152 are the prior art, and are not described herein again.
Referring to fig. 3, in an embodiment, the wiring connection device 100 further includes a conductive slip ring and a second conductive wire 170. The conductive slip ring comprises an inner ring 161 and an outer ring 162. The outer ring 162 is sleeved on the inner ring 161 and electrically connected with the inner ring 161, and the inner ring 161 can rotate relative to the outer ring 162. The inner ring 161 is mounted to the reel 130 and can rotate in synchronization with the reel 130. The inner ring 161 is electrically connected to the other end of the first wire 140. One end of the second wire 170 is electrically connected to the outer ring 162, and the other end is used to electrically connect to the electric device outside the junction box 110.
Specifically, the specific structure and operation principle of the conductive slip ring are the prior art, and are not described in detail herein.
The other end of the first wire 140 may pass through the reel 130 and then be electrically connected to the inner ring 161, and the outer ring 162 is electrically connected to the second wire 170 since the inner ring 161 is electrically connected to the outer ring 162, so that the other end of the first wire 140 may be indirectly electrically connected to the electric device outside the junction box 110 by electrically connecting the second wire 170 to the electric device outside the junction box 110.
In this embodiment, the inner ring 161 may be fixedly connected to the reel 130, so that the inner ring 161 can rotate in synchronization with the reel 130. Since the other end of the first lead 140 is connected to the inner ring 161 and the inner ring 161 rotates in synchronization with the reel 130, the other end of the first lead 140 rotates in synchronization with the reel 130 when the reel 130 rotates, so that the first lead 140 is not easily twisted or broken, thereby prolonging the service life of the first lead 140.
The outer ring 162 and the box body 121 can be kept relatively fixed, and the outer ring 162 can be kept fixed. Since the second lead wire 170 is connected to the outer ring 162, the second lead wire 170 can be kept stationary and does not rotate with the reel 130, and the second lead wire 170 is not easily twisted and broken.
Further, the other end of the second wire 170 may be electrically connected to the conductor at the wire port 102 as described above, thereby indirectly achieving the electrical connection of the other end of the first wire 140 to the conductor at the wire port 102.
In one embodiment, the cluster block 120 has an outlet from which one end of the first wire 140 protrudes out of the cluster block 120. Referring to fig. 1 to 3, the wire connecting device 100 further includes a bracket 181 and a guide wheel 182. The bracket 181 is provided at the exit of the cluster block 120. The guide wheel 182 is mounted to the bracket 181 and can rotate relative to the bracket 181, the first wire 140 is engaged with the outer peripheral surface of the guide wheel 182, and the guide wheel 182 can be rotated by the friction force between the first wire 140 and the guide wheel 182 when the first wire 140 moves.
Specifically, a rotating shaft (not shown) may be provided on the bracket 181, and the guide wheel 182 is mounted to the bracket 181 through the rotating shaft such that the guide wheel 182 can rotate with respect to the bracket 181.
When the reel 130 rotates, the first lead wire 140 is pulled out of the case 111 or is received by the reel 130, so that the first lead wire 140 moves into the case 111 or out of the case 111. Since the first conductive wire 140 is engaged with the outer peripheral surface of the guide wheel 182, the guide wheel 182 is driven to rotate when the first conductive wire 140 moves, so that the guide wheel 182 can guide the moving direction of the first conductive wire 140 when the first conductive wire 140 moves, and at the same time, the resistance of the first conductive wire 140 during the movement can be reduced.
Since the bracket 181 and the guide pulley 182 are located at the exit of the cluster block 120, resistance at the exit of the cluster block 120 when the first wire 140 moves can be reduced.
In one embodiment, guide wheels 182 include a first guide wheel and a second guide wheel. The second guide wheel and the first guide wheel are arranged at intervals. The first wire 140 is respectively engaged with the first guide wheel and/or the second guide wheel, and one end of the first wire 140 passes through a gap between the first guide wheel and the second guide wheel and extends out of the wire collection box 120.
Specifically, the first guide wheel and the second guide wheel are respectively mounted on the bracket 181 through respective corresponding rotating shafts. One end of the first wire 140 passes through a gap between the first guide wheel and the second guide wheel and protrudes out of the cluster block 120, so that the first wire 140 can be engaged with the outer circumferential surface of the first guide wheel and/or the second guide wheel when moving. The first guide wheel and/or the second guide wheel can guide the moving direction of the first wire 140 and can reduce the moving resistance of the first wire 140.
As shown in fig. 1 to 3, the wiring connection device 100 further includes a limiting member 141 and a triggering member (not shown). The limiting member 141 is fixedly connected to a portion of the first wire 140 extending out of the wire collection box 120, and the first guide wheel and the second guide wheel can prevent the limiting member 141 from passing through a gap between the first guide wheel and the second guide wheel. When the reel 130 receives the first guide wire 140, the first guide wire 140 can drive the stopper 141 to press the first guide wheel and the second guide wheel. The trigger is disposed on the wire collecting box 120, and when the limiting member 141 presses the first guide wheel and the second guide wheel, the trigger can be indirectly triggered, and the control device can control the driving assembly to stop moving according to a trigger signal of the trigger.
Specifically, as shown in fig. 1 to 3, in the present embodiment, the limiting member 141 is spherical and is sleeved on the first conductive wire 140. The outer diameter of the limiting member 141 is greater than the distance of the gap between the first guide wheel and the second guide wheel, so that the limiting member 141 cannot pass through the gap between the first guide wheel and the second guide wheel, and therefore, when the limiting member 141 moves to the first guide wheel and the second guide wheel, the limiting member extrudes the first guide wheel and the second guide wheel.
When the drive assembly is in the first state and the drive reel 130 receives the first wire 140, the portion of the first wire 140 that protrudes outside the cluster block 120 moves into the cluster block 120. When the limiting member 141 moves to the first guide wheel and the second guide wheel, the limiting member 141 extrudes the first guide wheel and the second guide wheel, so that the extrusion force applied to the first guide wheel and the second guide wheel can be transmitted to the bracket 181, and the bracket 181 is driven to move, so that the bracket 181 can trigger the trigger member, and the trigger member sends a trigger signal.
The control device can control the driving assembly to stop moving according to the trigger signal of the trigger piece, so that the reel 130 can stop winding the wire in time, and the first conducting wire 140 can be prevented from being pulled apart due to excessive winding.
The trigger may be a microswitch, pressure switch, photoelectric switch, or the like.
In one embodiment, the wiring lug 100 further comprises a resilient member (not shown). The elastic member is connected with the bracket 181 and the line collecting box 120 respectively, and the bracket 181 has a first position and a second position, and when the first position, the bracket 181 is arranged with the trigger piece interval, and when the second position, the bracket 181 can trigger the trigger piece. When the limiting member 141 presses the first guide wheel and the second guide wheel, the first guide wheel and the second guide wheel can drive the bracket 181 to overcome the restoring force of the elastic member, so that the bracket 181 is switched from the first position to the second position.
Specifically, in the present embodiment, the elastic member may be a coil spring. The elastic member is located below the bracket 181. The bottom end of the elastic member is connected to the wire collecting box 120, and the top end is connected to the bracket 181. When the bracket 181 is at the first position, the restoring force of the elastic member supports the bracket 181, and at this time, the trigger member is located below the bracket 181 and maintains a certain distance from the bracket 181.
When the reel 130 is wound up and the limiting member 141 moves to the first guide wheel and the second guide wheel, the limiting member 141 presses the first guide wheel and the second guide wheel downward, so that the pressing force is indirectly transmitted to the bracket 181, the bracket 181 presses the elastic member downward and overcomes the restoring force of the elastic member, and the bracket 181 moves downward to the second position. The cradle 181 is closer to the trigger when in the second position than when in the first position, and the cradle 181 is capable of triggering the trigger when in the second position.
Referring to fig. 1, in one embodiment, the junction box 110 is further configured with a touch screen display 190. The parameters such as the storage length of the first wire 140, the rotation duration of the motor 151, the rotation speed and the like can be input in the touch display screen 190, and the input parameters can be transmitted to the control device, so that the control device can control the rotation speed, the rotation duration, the rotation distance and the like of the motor 151 according to the parameters, and further, the speed, the take-up length and the like during the take-up and pay-off can be conveniently controlled.
In one embodiment, a tool magazine is also provided within the junction box 110, which can be used to store a wiring tool or common parts, such as a screwdriver.
In one embodiment, a battery (not shown) may be disposed within the junction box 110. The battery is used to supply power to the control device, the touch display screen 190, the motor 151, and the like, so that the junction box 110 can be used anytime and anywhere without an external power supply.
Another embodiment of the present application further provides a testing device (not shown). The test device includes a test instrument electrically connected to either end of the first wire 140, and the wiring device 100 of any one of the above.
Specifically, one end of the first wire 140 is connected to the test instrument, and the other end is used for connecting to the device under test.
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.
