Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1 and 2, the utility model provides a fool-proof wiring structure, which comprises a terminal board 1 and a wiring terminal 2; the wiring terminal board 1 is provided with a plurality of wiring grooves 11, the wiring terminal 2 is provided with a wiring sheet 21, and the wiring sheet 21 is inserted in the wiring grooves 11; a plurality of inserting grooves 12 are formed in the terminal board 1; the cross-sectional shapes of at least 2 of the plurality of insertion grooves 12 are different; or at least 2 of the plurality of insertion grooves 12 have the same cross-sectional shape but different sizes; the connecting terminal 2 is provided with a plug-in sheet 22, and the plug-in sheet 22 is plugged into the plug-in groove 12 matched with the shape and size of the connecting terminal.
When the sectional shape of the plugging groove 12 is different, it may be a triangle, a quadrangle, a polygon, a circle, an ellipse, or the like.
Referring to fig. 1 and 2, preferably, the wiring groove 11 is arranged in parallel with the insertion groove 12 in the vertical direction, and the insertion groove 12 is located below the wiring groove 11 in the vertical direction.
Referring to fig. 2, preferably, the terminal board 1 includes four connection grooves 11 for connecting a live wire, a neutral wire, a power wire and a control signal wire, respectively, four insertion grooves 12 are disposed below the four connection grooves 11 in a vertical direction, and the four insertion grooves 12 correspond to the insertion pieces 22 of the four connection terminals 2 one to one. The cross-sectional shapes of the four insertion grooves 12 are square, the widths or heights of the four insertion pieces 22 are different from each other, and particularly, if the widths and heights of the two insertion pieces 22 of the positive electrode and the negative electrode are the same without distinguishing the positive electrode and the negative electrode, the widths or heights of the two insertion pieces 22 connected with the power line and the control signal line are different.
It should be noted that the wiring groove 11 and the plugging groove 12 are not limited to be arranged in parallel in the vertical direction, and the wiring groove 11 and the plugging groove 12 may also be arranged in the left-right direction.
Therefore, the utility model arranges the splicing grooves with different cross-sectional shapes or the same cross-sectional shape but different sizes on the terminal board, the connecting terminal is provided with the corresponding splicing pieces, the splicing pieces can not be exchanged, on one hand, the physical fool-proofing is achieved, the wrong wiring is avoided, and the motor is prevented from being burnt; on the other hand, simple structure, simple to operate is understandable, has improved the work efficiency of wiring.
Referring to fig. 1 and 2, the plug 22 of the connection terminal 2 includes a plug portion 221 and a connection portion 222, one end of the connection portion 222 is connected to the terminal 21, the other end of the connection portion 222 is connected to the plug portion 221, and the terminal 21 is parallel to the plug portion 22.
Preferably, the connection portion 222 is obliquely disposed.
Therefore, the utility model discloses a set up connecting portion slope to reduced the insertion stroke of the grafting portion that links to each other with it, further improved the work efficiency of wiring.
Referring to fig. 2, preferably, the free end of the insertion part 221 of the connection terminal 2 is flush with the free end of the tab 21. If the inserting part is too short, the inserting part does not enter or is not completely inserted into the groove, the lug plate is inserted into the wiring groove, wiring errors can be caused, and if the inserting part is too long, the inserting stroke is long, and wiring efficiency is low. Therefore, the utility model discloses a with the free end parallel and level of the free end of grafting portion and lug, further ensure the exactness of wiring position.
Referring to fig. 2, the tab 21 is fixed to the wiring recess 11 by a screw 13. Therefore, the utility model discloses a screw fastening connection avoids the not hard up at wiring position, guarantees the stability and the reliability of wiring.
Referring to fig. 2, the tab 21 and the plug 22 of the terminal 2 are integrally formed. Therefore, the utility model discloses an integrated into one piece's binding post, the processing of being convenient for.
Referring to fig. 2, the notch edge of the insertion groove 12 is provided with a chamfer and/or the free end of the insertion part 221 is provided with a chamfer. Therefore, the utility model discloses a set up the chamfer, realize the direction installation, further improve the work efficiency of wiring.
Referring to fig. 3, the cross-sectional shape of the insertion part 221 is square, and has different widths, the insertion groove 12 and the insertion part 221 are in clearance fit, the width of the insertion part 221 is smaller than the width of the insertion groove 12 by 0.5-1mm, that is, the single-side margin C between the insertion groove 12 and the insertion part 221 is between 0.25-0.5 mm.
If the allowance is too small, the manufacturing error can influence whether the inserting part can be smoothly inserted into the inserting groove; if the surplus is too big, lead to the grafting recess too big easily, other big grafting portions can also be inserted to the grafting recess that little grafting portion corresponds, lead to the wiring mistake, do not play the effect of preventing slow-witted. Therefore the utility model discloses a reasonable scope needs to be set for to the unilateral surplus between recess and the grafting portion of pegging graft to guarantee that grafting portion inserts the grafting recess smoothly, and avoid connecing wrong line, play the effect of preventing slow-witted.
The width dimension difference of the plugging parts 221 of any two of the connecting terminals 2 is larger than 1 mm. Due to the fact that the width difference between the plugging part 221 and the plugging groove 12 is 0.5-1mm, the situation that two plugging parts with close sizes can be replaced to cause wrong wiring is prevented. Therefore, the utility model discloses a width dimension difference that sets up arbitrary two binding post's grafting portion is greater than grafting portion and the maximum value of grafting recess width difference to prevent that the transposition of grafting portion of two variation in size from leading to wrong wiring, prevent that the motor from burning out.
An air conditioner includes above-mentioned prevent slow-witted wiring structure.
