The specific principle is as follows: after the elastic supporting part 3 is elastically abutted against the inner side wall of the box body opposite to the side edge 51, the elastic supporting part 3 can be subjected to a reverse acting force F1 applied by the inner side wall of the box body, the reverse acting force F1 drives the lead support to rotate anticlockwise for a certain angle so as to enable the fixing part 1 to move towards the direction far away from the side edge 51, so that the buckling position of the end part of the buckle 11 is pressed on the side surface of the side edge 51, which is far away from the fixing part 1, the fixing part 1 is tensioned and fixed, and the phenomena that the fixing part 1 shakes relative to the frame 5 and leads to lead breakage due to shaking are avoided, therefore, the mounting stability and the firmness of the lead support are improved, and the risk of lead breakage is avoided; meanwhile, due to the design, the lead wire support can be disassembled without other tools, so that the production efficiency is improved, and the manufacturing cost is reduced.
In order to further improve the installation stability of the lead frame, the buckle 11 in this embodiment is a bidirectional buckle, and two buckling positions of the bidirectional buckle deviate from the setting along the length direction of the lead channel 2 or deviate from the setting along the up-down direction, so that compared with a single buckle, the bidirectional buckle increases the number of the buckling positions and the pressing contact area between the buckle 11 and the side 51, thereby improving the clamping stability between the buckle 11 and the frame 5 and avoiding the lead frame from shaking.
Elastic support portion 3 in this embodiment is the shell fragment, the easy integrated into one piece shaping of shell fragment, can simplify lead wire support's processing technology, the shell fragment has the portion 31 of arching towards keeping away from 1 orientation hunch-up of fixed part, the longitudinal section of the portion 31 of arching is bow-shaped or semi-circular, the portion 31 of arching and washing machine's box inner wall elasticity butt, the setting of the portion 31 of arching improves elastic support portion 3's elasticity butt stability, avoid taking place the slippage phenomenon, fish tail box inner wall when bow-shaped or circular shape portion of arching can also avoid the shell fragment to assemble simultaneously.
The fixing portion 1 in this embodiment further includes a pin head 12 installed on the fixing plate 10, the pin head 12 and the buckle 11 are installed on the same side of the fixing plate 10, the pin head 12 and the buckle 11 are arranged along the length direction of the lead channel 2, and the pin head 12 passes through the side 51 and is attached to one side of the side 51 departing from the fixing portion 1, so that the fixing portion 1 can be further positioned, the fixing portion is prevented from shaking relative to the frame 5, and the installation stability of the lead frame is further improved.
It is understood that the present invention can also provide a groove on the frame, the opening of the groove is oriented to be substantially parallel to the lead channel, for example, towards the buckle or away from the buckle, and the pin head is inserted into the groove to be positioned, so as to achieve the basic effect of the embodiment, and the detailed description is omitted here.
In order to make the lead wire pack into lead wire passageway 2 fast, lead wire passageway 2 in this embodiment deviates from the open setting in one side of fixed part 1, in leading wire passageway 2 is adorned from this side to the convenient lead wire, lead wire support is still including establishing a plurality of turn-ups 13 that open one side and interval set up, turn-ups 13 integrated into one piece on the diapire of lead wire passageway 2, upset turn-ups 13 back downwards, the lead wire is adorned into in lead wire passageway 2 from this side, upset turn-ups 13 back upwards, turn-ups 13 is fixed in order to restrict the lead wire in lead wire passageway 2 with the roof joint of lead wire passageway.
In order to make the overall structure of the lead frame more compact, the elastic support portion 3 is disposed on the flip 13 in the embodiment, and is preferably integrally formed with the flip 13, so that the elastic support portion 3 can be prevented from interfering with the lead to be loaded into the lead channel 2 after the flip 13 is turned downward. Of course, it is understood that the elastic support portion may also be mounted on the top wall of the wire guiding channel and formed by extending upward from a side of the top wall of the wire guiding channel facing away from the fixing portion.
It can be understood that the turnbuckle can be integrally formed on the top wall of the lead channel, the lead is arranged in the lead channel from the side after the turnbuckle is turned upwards, and the turnbuckle is clamped and fixed with the bottom wall of the lead channel after the turnbuckle is turned downwards so as to limit the lead in the lead channel.
After the lead frame is installed, if the lead is under the action of pulling force F3, the lead frame has a tendency of rotating clockwise as a whole with the contact point of the fixing part 1 and the side 51 as a fulcrum under the action of external force, at this time, the buckle 11 will receive a reaction force F2, and the elastic support part 3 will be separated from the inner side wall of the box body, namely, will not abut against the inner side wall of the box body, and F1 will disappear. In order to avoid that F2 is too large and the clip 11 is structurally damaged to make the lead frame come off, in this embodiment, a hollow groove 101 is further disposed on one side of the fixing plate 10 facing the side 51, the hollow groove 101 and the clip 11 are both located above the lead channel 2, and the hollow groove 101 is farther from the lead channel 2 than the clip 11, that is, the hollow groove 101 is located above the clip 11, so that the fixing plate 10 is pressed against the side 51 toward the elastic support portion 3 and then is located on one side of the hollow groove 101 away from the clip 11 together with the contact fulcrum O of the side 51. According to the lever principle, F2 × L2 is F3 × L3, that is, F2 is F3 × L3/L2, since the size of F3 is fixed, the smaller L3/L2 is, the smaller F2 is, and the smaller L3/L2 is (L2+ L)/L2 is 1+ L/L2, so the larger L2 is, the smaller L3/L2 is, and the smaller the reaction force F2 received by the buckle 11 is, so that in the present embodiment, by providing the hollow groove 101, the contact point between the fixing portion 1 and the side 51 is as close to the upper end of the fixing plate 10 as possible, so as to reduce the ratio of L3/L2, further reduce the reaction force F2 received by the buckle 11, and avoid structural damage to the buckle 11, and after adopting the above scheme, the lead frame can bear the lead tension F3 above 60N.
It can be understood that a hollowed-out groove can be arranged on one side of the side edge facing the fixed plate, the hollowed-out groove is positioned above the clamping hole, and the clamping hole is positioned above the lead channel; or set up the boss in one side of fixed plate orientation side, boss and buckle all are located the top of lead wire passageway, and the boss compares the buckle and keeps away from the lead wire passageway, so the design also can reach the basic effect of this embodiment, and no longer detailed here.
It can be understood that, if the frame is an inverted U-shaped shelf, when the other side of the shelf extends downward to the position of the arch part, the elastic support part abuts against the other side of the frame, that is, the frame, so that the basic effect of the present embodiment can be achieved.
As shown in fig. 1, the lead frame in this embodiment further includes an L-shaped supporting plate 14 disposed at one end of the lead channel and bent and extended obliquely downward, a winding groove 141 is disposed on the supporting plate 14, and the binding wire is wound in the winding groove 141 to limit the lead on the supporting plate 14.
In order to omit the assembly of the lead frame, the lead frame is preferably integrally formed by an injection molding process in this embodiment.
The fixing part comprises a fixing plate and a buckle formed by extending one side of the fixing plate, which is far away from the elastic sheet, towards the direction far away from the elastic sheet, the buckle is clamped on the clamping hole on the side edge, and the elastic sheet is elastically abutted against the box body or the frame, so that the fixing plate moves towards the direction close to the side edge and is tightly pressed on the side edge, which faces the fixing plate, the fixing part is tensioned and fixed, and the lead support is prevented from shaking.
Example II,
Compared with the first embodiment, the difference of the present embodiment is that the fixing portion and the elastic supporting portion are both disposed on the same side of the lead channel, and the fixing portion and the elastic supporting portion are arranged at intervals or arranged at intervals up and down along the length direction of the lead channel, so that after the arching portion of the elastic supporting portion elastically abuts against one side of the side facing the fixing portion, the fixing portion can be tensioned and fixed while keeping a tendency of being away from the mounting portion.
Of course, besides the fixing part being clamped on the frame and the elastic supporting part being elastically abutted on the frame, the invention can also clamp the fixing part on the box body and the elastic supporting part being elastically abutted on the box body.
