Description

Line concentration box and electrical equipment
Technical Field
The invention relates to the technical field of electrical accessories, in particular to a line concentration box capable of meeting the internal line concentration requirement of electrical equipment.
Background
The existing line concentration box comprises a shell, a reel, a coil spring, a pawl and a spring, wherein the reel is provided with a reel shaft positioned at the axis of the reel, one side of the axial direction of the reel is provided with a ratchet part, the reel is rotatably installed in the shell around the axis of the reel, and the coil spring is connected between the reel and the shell. The periphery of the shell is provided with two opposite wire outlets, and after the electric wire is wound on the reel, two opposite ends of the electric wire are respectively led out from the two wire outlets. The pawl is floatingly provided along the radial direction of the reel by a spring, and is kept engaged with the ratchet part under the action of the spring to realize the rotation stop of the reel. When the user pulls the wire, the spool is forced to rotate about the second direction, tending to pull the wire out and store the coil spring, and the spool is held in the current position with the ratchet teeth engaged. And after the pawl is shifted to release the pawl from the ratchet part, the coil spring rotates the coil disc around the first direction to be wound. The existing wire concentration box realizes the functions of automatic winding of redundant wires, unidirectional rotation of a reel and the like. The existing line concentration box is mainly applied to fixed electric lines or fixed line groups of a specific electric appliance for collection, such as electric lines of electric hair dryers, fans and mice.
It is now necessary to use such a roll-up type of junction box for the concentration of internal wiring of electrical equipment. The equipment unit starts and stops or the wire winding process can make the strong electric wire near weak electric wire produce current fluctuation and form induced current, and the problem that current such concentrator has is that the interference that can't effectively eliminate induced current in the line concentration box produced influences weak electric wire signal transmission stability.
Disclosure of Invention
The first object of the present invention is to provide a hub box that meets the internal hub requirements of electrical equipment and solves the problem of induced current interference.
The second object of the present invention is to provide an electrical apparatus that meets the internal line concentration requirement of the electrical apparatus and solves the problem of induced current interference.
The first object of the invention provides a line concentration box which comprises a shell and a line winder, wherein a line concentration space is formed in the shell, a line outlet communicated with the interior of the shell is arranged on the shell, and the line winder is rotatably connected with the shell along the axis and extends to the line concentration space; the line concentration box comprises a grounding terminal and an induced current eliminating circuit, wherein the grounding terminal is connected with the shell and extends between the inside and the outside of the shell; the induction current eliminating circuit is arranged in the shell and comprises an electrostatic shielding conductor and a warning circuit, the electrostatic shielding conductor and the grounding terminal are sequentially and electrically connected, and the warning circuit comprises a warning device.
According to the scheme, when the induced current occurs, the induced current is led in from the electrostatic shielding conductor such as a copper column and becomes the generated induced current to become a power supply in a loop, and a warning device such as an indicator lamp or a loudspeaker emits a light signal or a sound signal, so that an operator can judge that the current wire generates the induced current according to the light signal or the sound signal; in addition, the loop is connected to the ground wire through the ground terminal, so that induced current can flow out through the ground wire, interference to other weak wires nearby the strong wire can be avoided, and the wires in the device can be shielded from the induced current. Furthermore, the shell is also made of ferrite materials, when the shell faces external high-frequency noise, the ferrite shell can block the interference of the high-frequency signals on the internal wiring harness, avoid the distortion of the internal wiring harness signals, enable normal and useful signals to be smooth, and simultaneously can play a good role in inhibiting the high-frequency interference signals.
The further proposal is that the line concentration box also comprises a unidirectional rotation mechanism arranged between the shell and the line winder; the unidirectional rotation mechanism comprises a pawl, a ratchet wheel and a first elastic piece; the ratchet wheel is connected with the shell, the pawl is movably connected with the winder, and the pawl is forced to be meshed with the ratchet wheel under the action of the first elastic piece.
From the above, the pawl in the unidirectional rotation mechanism moves along the first direction during the winding process, and the rotation is not blocked before the wire harness is tightened. After the wire harness is tightened and loosened, the pawl is tightly meshed with the ratchet wheel under the action of the elastic force of the first elastic piece like a metal spring piece, so that the wire winder cannot rotate reversely at the moment, and the wire collecting box is kept at the current winding degree and cannot loosen the wire harness.
The ratchet wheel is rotationally connected with the shell around the axle center; the line concentration box also comprises a rotation stopping structure which is adjustably connected to the shell and can be adjusted to a position for limiting the rotation of the ratchet wheel; a grounding screw at the grounding terminal position, wherein the grounding screw is in threaded fit with the shell, the grounding screw is used as a rotation stopping structure, and the ends of the grounding screw are abutted on the surface of the ratchet wheel and are electrically connected with each other; the electrostatic shielding conductor is in contact with the unidirectional rotation mechanism and is electrically connected to each other.
In view of the above, the above solution can well maintain the winding effect, but the disadvantage is irreversible, and once the winding is excessive, the winding cannot be released when a longer wire bundle is required. Therefore, in the present further embodiment, the ratchet is provided in a rotatable structure with respect to the housing, and in the case where the ratchet is not in a rotation stopping structure, even if the ratchet is engaged with the pawl, the ratchet does not restrict the reel and the pawl from reversing, and thus the reverse unreeling can be performed. In the winding process, only the rotation stopping structure is required to be adjusted to limit the rotation of the ratchet wheel, and the ratchet wheel is equivalent to the fixed arrangement and can not rotate, so that the wire winder can be subjected to unidirectional rotation stopping when the wire harness is wound. The grounding screw is directly used as a rotation stopping structure of the ratchet wheel, and the rotation of the ratchet wheel can be stopped by tightening the grounding screw to squeeze the ratchet wheel. The arrangement can simplify the structure, is beneficial to small-volume design, and further reduces the occupation of the internal space of the electrical equipment. More importantly, the electrostatic shielding conductor is electrically connected with the grounding screw through the unidirectional rotating mechanism made of metal materials, and the unidirectional rotating mechanism and the grounding screw complement each other in the narrow junction box to complete the functions of each other.
In addition, the induction current eliminating circuit further comprises an electric brush, the warning circuit comprises a resistor, the warning device comprises an indicator lamp, and the grounding screw, the electrostatic shielding conductor, the electric brush, the indicator lamp and the resistor are electrically connected in sequence.
Therefore, the indicator lamp has low power consumption, and the indicator lamp can be lightened when the small induced current passes through the loop, so that the warning effect can be better ensured.
The reel comprises an operating part and a winding part which are sequentially arranged in the axial direction of the reel, wherein the operating part is arranged outside the shell, the winding part is arranged inside, and a line concentration space is formed at the periphery of the winding part inside; the wire winding portion comprises at least two wire winding arms, wherein on a plane perpendicular to the axis, two adjacent wire winding arms are arranged at intervals and form a wire passing position, and the wire passing position, the wire collecting space and the wire outlet are sequentially communicated.
From the above, it is now required to use the winding type line concentration box for line concentration of internal wiring of electrical equipment. Taking the energy storage liquid cooling equipment as an example, the electrical design is at the end of a design development time node, and the placement positions of related devices cannot be determined as early as possible, so that the length of a wire harness cannot be determined, and the wire harness with enough length and even redundancy is provided, so that the wire concentration requirement is generated. Further, when coping with the wire concentration of the internal wiring of the electrical equipment, there is a further need for a wire concentration box which is independent from the wire harness, is used as it is, and can be used as it is and can be rolled up to collect wires as required before wiring. The existing wire concentration box used by binding with one wire is extremely difficult to operate, and the wire harness can not be assembled and used basically, so that each wire harness needs to be provided with one wire concentration box, and the cost problem and the space occupation problem can be caused. Compared with the single-shaft mode adopted by the winding type line concentration box in the background art, when the electric wire in the electric equipment is overlong and needs to be wound, the electric wire only needs to extend into the shell from the line outlet and extend out of the original line outlet or the other line outlet after bypassing the line passing position between any two line concentration arms, the worker only needs to operate the operation part to rotate the line winder, and the two or more line concentration arms force the electric wire to be wound and hidden in the line concentration space. Of course, the electric wires can be extended outwards by the reverse operation part, so that the line concentration box can be assembled and used at any time, has the characteristics of simple line concentration winding and length adjustment operation, and can well meet the line concentration requirement in the electric equipment on the premise of lowest cost and smaller occupied space.
In still another aspect, the plurality of winding arms are disposed at circumferential positions of the shaft center at intervals along the circumferential direction of the shaft center, and the winder forms a thread passing space at the inner circumferences of the plurality of winding arms, the thread passing space being communicated between any two thread passing positions.
Therefore, the one or more rolled wire harnesses are more regularly hidden in the annular wire collecting space, the narrow internal wire collecting space can be better utilized, and the force distribution is more uniform, so that the operation of the operation part is smoother no matter the wire harnesses are rolled or unrolled.
In a still further proposal, a clamping groove is arranged at one end of the shell opposite to the operating part in the axial direction of the reel; the clamping groove is used for being clamped with the operating part of the other line concentration box, and/or the line concentration box further comprises a mounting connecting piece, wherein the mounting connecting piece comprises a mounting connecting part and a buckle which are oppositely arranged, and the clamping groove is detachably matched with the buckle.
As can be seen from the above, this arrangement makes the junction box a modular structure. The plurality of line concentration boxes can be overlapped and fixed together through the matching of the clamping groove and the operating part; the installation connecting piece can carry out the part of erection joint with electrical equipment such as bandage, ribbon, buckle and couple, and the buckle on the installation connecting piece cooperates with the draw-in groove on the line concentration box and makes the line concentration box can be fixed in the inside specific position of electrical equipment, more does benefit to the inside wiring of pleasing to the eye electrical equipment.
In a still further aspect, the housing includes a first half and a second half relatively movable in an axial direction of the reel; after the first half body and the second half body move along the axial direction in a back-to-back way, the shell can be changed to a capacity expansion state so as to enlarge the line concentration space.
From the above, the number of the wires required for the wire concentration box arranged inside the electrical equipment is not fixed, and may be one or more, but if the wire concentration is directly made large enough to meet the space requirement of a plurality of wire harnesses, the space occupation problem described in the background art still can be caused. Therefore, the shell is made into a telescopic form, mainly, the shell is made into two half bodies which can move relatively along the axial direction, when the quantity of the wires to be collected is small, the shell can be transformed into a state with the smallest volume, and when the quantity of the wires to be collected is large, the shell is transformed into a capacity-expanding state to enlarge the wire collecting space. The arrangement solves the problem that the internal space occupied by the electrical equipment is not fixed in the line concentration requirement, ensures that the line concentration requirements of different numbers are met, and simultaneously reduces the occupation of the internal space of the equipment as much as possible.
Still further, the line concentration box further comprises a locking piece and a second elastic piece; the locking piece is movably connected to the first half body, the second elastic piece is connected between the locking piece and the first half body, and the second half body is provided with a buckling opening; when the shell is in the capacity-expanding state, the locking piece is buckled with the buckling opening.
Therefore, the arrangement and the matching of the locking piece, the second elastic piece and the locking opening can ensure that the line concentration box is stably kept in the capacity expansion state, and the phenomenon that the internal line bundle is extruded or even damaged due to unstable form is avoided.
The second object of the invention provides an electrical apparatus comprising a connection line and a junction box as described above, the junction box winding up at least a portion of the connection line.

In addition, a clamping groove 102 is further formed in the axial end of the first half 11 facing away from the second half 12, and a mounting opening connected to the inside of the housing 1 is formed in the axial end of the second half 12 facing away from the first half 11.
Referring to fig. 1 and 2, the reel 2 includes an operating portion 21, a winding portion 22, and a turntable 23 fixedly disposed in this order in the axial direction thereof. The operating portion 21 in the present embodiment is a knob, and when the operating portion 21 is operated, the reel 2 can be rotated forward or backward around its own axis. The winding part 22 is cylindrical as a whole, and the reel 2 is also connected with the housing 1 in a rotating manner around its own axis by means of the cooperation of the winding part 22 and the mounting opening of the second half body 12. Further, six winding arms 221 are formed on the peripheral wall of the winding portion 22 at circumferentially spaced and uniform positions along the axial center, and a wire passing position 220 is formed between any two adjacent winding arms 221, so that the six wire passing positions 220 are uniformly distributed along the circumferential direction of the axial center; further, the inner circumferences of the plurality of winding arms 221 form a thread passing space 20, and the thread passing space 20 communicates between any two thread passing positions 220. The turntable 23 is a disk centered on the axis, and the turntable 23 is mainly used to link with the unidirectional rotation mechanism 3.
Referring to fig. 3, the number of the outlets 101 located at the outer periphery of the housing 1 is six, and the six outlets 101 are uniformly distributed along the circumferential direction of the axis, so that one outlet 101, one side of the line concentration space 100, one line passing position 220, the line passing space 20, the other side of the line concentration space 100, the other line passing position 220 and the other outlet 101 are sequentially communicated along a straight line. With this arrangement, the wire harness can easily pass through the wire collecting space 100, the wire passing position 220 and the wire passing space 20 and out from the other opposite wire outlet 101 after being inserted into the wire collecting box, so that the operation difficulty can be well reduced.
With continued reference to fig. 1 and 2, the unidirectional rotation mechanism 3 includes a pawl 32, a ratchet 31, and a first elastic member 33. In the embodiment, the ratchet wheel 31 is annular, and an inner ratchet is arranged on the inner peripheral surface of the ratchet wheel 31; the pawl 32 is swingably connected to the turntable 23, and is located at a circumferential position of the axial center of the reel 2 and at the inner periphery of the ratchet 31.

In addition, the grounding screw 4 is screw-fitted with the first half 11 and located at a circumferential position of the axial center of the reel 2, the nut of the grounding screw 4 is located outside the first half 11, the grounding screw 4 extends in the axial direction and protrudes into the inside of the housing 1, and when the grounding screw 4 is screwed down, the end of the screw thread section thereof will abut on the axial surface of the ratchet 31 and prevent the ratchet 31 from rotating. Thus, the grounding screw 4 is used as the rotation stopping structure adjustably connected to the housing 1, and the rotation stopping structure can be adjusted to a position for limiting the rotation of the ratchet wheel 31.
Referring to fig. 4 again, compared with the single shaft form adopted by the winding type wire collecting box in the prior art, when the electric wires in the electric apparatus are too long and need to be wound, the wire collecting box of the embodiment firstly tightens the grounding screw 4 to fix the ratchet 31, at this time, only the electric wires need to extend from the wire outlet 101 into the housing 1 and bypass the wire passing position 220 between any two wire collecting arms 221 and then extend from the original wire outlet 101 or another wire outlet 101, the operator only needs to operate the operating part 21 to rotate the wire winder 2 forward, two or more wire collecting arms 221 force the electric wires to wind and be hidden in the wire collecting space 100, as shown in fig. 4, three electric wires of the first electric wire 91, the second electric wire 92 and the third electric wire 93 are wound simultaneously, one ends of the first electric wire 91, the second electric wire 92 and the third electric wire 93 are led out from different three wire outlets 101 respectively, and the other ends of the three wires become wire bundles led out from the same wire outlet 101. When the ground screw 4 is loosened, the rotation restriction of the ratchet wheel 31 is released, and at this time, even if the ratchet wheel 31 and the pawl 32 are engaged, the ratchet wheel 31 does not restrict the reel 2 and the pawl 32 from reversing and rotating together therewith, so that the reverse unreeling can be performed. On the other hand, the rotation-stopping structure directly using the ground screw 4 as the ratchet 31 can be stopped by pressing the ratchet 31 by tightening the ground screw 4. The arrangement can simplify the structure, is beneficial to small-volume design, and further reduces the occupation of the internal space of the electrical equipment.

Referring again to fig. 11 and 12, the clamping slot 102 can be used not only to realize the overlapping and expanding use of a plurality of hub boxes, but also to combine with the mounting connector to realize the fixation of the hub boxes. As shown in fig. 11, the mounting connection member is a strap member 71, one end of the strap member 71 is a mounting connection portion of a strap having tooth surfaces, velcro or adhesive, and the opposite end is a buckle 711 having an outer contour corresponding to the outer contour of the operation portion 21, that is, the inner contour of the clamping groove 102, and the buckle 711 is detachably engaged with the clamping groove 102. Therefore, the binding band is bound on the internal structure of the electrical equipment, and the line concentration box can be fixed. Similarly, the mounting connection shown in FIG. 12 is a strap member 72, with the strap member 72 having straps and snaps 721 at opposite ends, respectively. Therefore, the buckle on the installation connecting piece is matched with the clamping groove on the junction box, so that the line concentration box can be fixed in a specific position inside the electrical equipment, and the line distribution inside the electrical equipment is more beneficial to attractive appearance.
Second embodiment of the hub
Referring to fig. 13 and 14, in this embodiment, only one outlet 8101 is provided on the housing 81, so that the wire harness needs to be fed out from the same outlet 8101 after entering from the outlet 8101 and bypassing the wire winder 82, and when the outlet 8101 is smaller, the problem of greater operation difficulty exists, and of course, the size of the outlet 8101 can be increased to solve the problem.
In addition, in the present embodiment, the reel 82 is provided with only two reel arms: the first winding arm 821 and the second winding arm 822, and the second winding arm 822 is not located at the circumferential position of the shaft center but at the shaft center.
