Description

Technical Field

[0001] The utility model relates to the technical field of junction boxes, in particular to a motor capacitor mounting clamp and a junction box containing the same. Background Art

[0002] At present, the common method of fixing the motor capacitor is to use a clamp 13 to fix the capacitor, and then use a fastening screw 4 to fasten it (such as Figure 1 As shown). The clamp 13 is usually a metal part, and its design often has the following problems: 1. The structure of the clamp 13 is designed according to the size of the capacitor 6 and then formed by stamping, so it often presents a single structure. For capacitors of different sizes, the clamp 13 needs to be re-molded; 2. The size is difficult to confirm. When designing the size of the clamp, it is necessary to consider the height of the fixed end, the diameter of the capacitor, and the center position of the capacitor cross section, and the interference. If the size is too small, it cannot be installed and fixed; if the size is too large, the capacitor is easy to shake during the operation of the motor and generate noise. Therefore, although the structure of the clamp is simple, due to its singleness, it cannot be shared by multiple motors, and even the mold life will be affected by multiple mold repairs due to size adjustments.

[0011] Furthermore, the included angles between the fixing portion and the first crimping portion, and between the connecting portion and the second crimping portion are all obtuse angles.

DETAILED DESCRIPTION

[0039] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0040] like Figure 2 , Figure 3 As shown, a motor capacitor mounting clamp includes a fixing member 1 and a movable member 2, the fixing member 1 includes a fixing portion 101 and a first crimping portion 102 connected to each other; the fixing portion 101 is fixed to a terminal 3 in a junction box; the movable member 2 includes a connecting portion 201 and a second crimping portion 202 connected to each other, the connecting portion 201 is movably connected to the first crimping portion 102 so that the first crimping portion 102 and the second crimping portion 202 are respectively in contact with the outer surface of the capacitor 6; the first crimping portion 102, the second crimping portion 202 and the inner bottom surface of the junction box fix the capacitor 6 by balancing the forces acting in three directions.

[0041] The fixing part 101 is fixed to one end of the first crimping part 102, the other end of the first crimping part 102 is connected to the connecting part 201, one end of the connecting part 201 is connected to the first crimping part 102, and the other end is fixed to the second crimping part 202. The fixing part 101 is used to fix the position of the clamp, the connecting part 201 is used to connect the movable part 2 to the fixing part 1, the first crimping part 102 and the second crimping part 202 are used to press the capacitor 6, and the first crimping part 102 is also used as a structure connected to the connecting part 201.

[0042] The movable connection between the first crimping part 102 and the connecting part 201 can be realized by bolt connection or mutual sleeve connection. When bolt connection is used, the connection position can be adjusted by designing a waist-shaped hole (not shown in the drawings), and the relative position of the first crimping part 102 and the connecting part 201 can be adjusted according to the different sizes of the capacitor 6. Mutual sleeve connection means that the first crimping part 102 or the connecting part 201 is provided with a matching hole 5 for the other party to insert, and different sizes of capacitors 6 can be clamped by different insertion depths.

[0043] During installation, place the capacitor 6 at a suitable position (some have capacitor slots), position the fixing part 101 of the fixing part 1 on the terminal 3 through the fastening screw 4 (the fastening screw 4 is not tightened), place the movable part 2 above the capacitor 6, and then adjust the relative position of the movable part 2 and the fixing part 1 according to the size of the capacitor 6, and finally lock and fix it.

[0044] Compared with the common capacitor 6 fixing structure, the utility model shows its versatility. By adjusting the cooperation between the fixing part 1 and the movable part 2, the capacitor 6 of different sizes and specifications can be fixed. Therefore, the need for simple parts and molds of different sizes is reduced. At the same time, the traditional fixing structure often requires strict size control. If the size is not appropriate, problems such as failure to install or loose installation will occur, resulting in noise during operation. Since the clamp can be freely adjusted in the utility model, the size of the capacitor 6 can be adapted by tightening the screw 4 and the cooperation between the two parts, so the above problems can be effectively avoided.

[0045] like Figure 3 As shown, the force exerted by the bottom surface of the junction box on the capacitor 6 is usually vertically upward, so the points of action of the first crimping part 102 and the second crimping part 202 on the capacitor 6 are located on both sides above the center of gravity of the capacitor 6. When in use, point D of the fixing part 101 is subjected to the pressure of the fastening screw 4 and is fastened to the terminal 3; point A at the bottom is subjected to the support force of the capacitor 6; point B between the first crimping part 102 and the capacitor 6 and point C between the second crimping part 202 and the capacitor 6 are subjected to mutual force, and due to the pressure of point A on the capacitor 6, the forces of points A, B and C are balanced, so that the capacitor 6 is fixed.

[0046] The fixing portion 101 and the first crimping portion 102 of the fixing member 1 are preferably integrally formed, and the connecting portion 201 and the second crimping portion 202 of the movable member 2 are preferably integrally formed.

[0047] The surface of the fixing portion 101 in contact with the terminal 3 is preferably a plane. Furthermore, the fixing portion 101 is a horizontal panel, which refers to a panel placed horizontally and having a plane surface.

[0048] There are many choices for the shapes of the fixing member 1 and the movable member 2, wherein the fixing portion 101 of the fixing member 1 is a horizontal panel, and the first crimping portion 102 can be an arc plate or a straight plate (such as Figure 3 and Figure 7 As shown in FIG. 1 ), the straight plate refers to a panel with a flat surface. The first crimping portion 102 extends obliquely upward from the fixing portion 101 and cooperates with the connecting portion 201. The first crimping portion 102 extending in an arc shape or a plane shape can achieve contact with the surface of the capacitor 6. Similarly, the movable member 2 can be an arc plate or a straight plate or an L-shaped folded plate bent at a certain angle, such as Figure 6 The movable part 2 shown is an arc-shaped plate. Figure 5 The movable part 2 shown is a straight plate. Figure 4 The movable member 2 shown is an L-shaped folded plate, that is, the connecting portion 201 and the second crimping portion 202 are arranged obliquely.

[0049] When the first crimping portion 102 or the movable member 2 is an arc-shaped plate, it is preferably bent toward the side where the capacitor 6 is located, that is, the center of the arc-shaped plate is located inside the capacitor 6 .

[0050] When the first crimping part 102 and the connecting part 201 are connected by the matching hole 5, no additional connecting piece is required for fixing. The matching hole 5 can be located on the first crimping part 102 (in this case, the connecting part 201 is sleeved in the matching hole 5), or the matching hole 5 can be located on the connecting part 201, in this case, the first crimping part 102 is sleeved in the matching hole 5; the following describes two specific matching structures with the matching hole 5 located on the first crimping part 102:

[0051] The common points of the two matching structures are: a matching hole 5 is set at the end of the first crimping part 102 away from the fixed part 101, the height of the matching hole 5 is slightly larger than the thickness of the movable part 2, the matching hole 5 is a long strip hole, and the height of the matching hole 5 refers to the short side dimension of the cross section of the matching hole 5. The height dimension of the matching hole 5 cannot be too large, otherwise it will cause the connecting part 201 to slide in the matching hole 5. The relative fixation of the connecting part 201 and the first crimping part 102 is achieved through the limiting of the matching hole 5, the capacitor 6 and the fastening screw 4.

[0052] The first coordination structure: Figure 4-Figure 7As shown, the connecting portion 201 and the second crimping portion 202 have an angle, and the angle means that the two are not in the same plane. When the fixing member 1 and the movable member 2 fix the capacitor 6, the matching hole 5 is located close to the connection between the connecting portion 201 and the second crimping portion 202, and the capacitor 6 is clamped in the triangular space a formed by the first crimping portion 102 and the second crimping portion 202. At this time, the clamping range of the first crimping portion 102 and the second crimping portion 202 is small, which is suitable for fixing a small capacitor 6. Since the matching hole 5 is close to the connection between the connecting portion 201 and the second crimping portion 202, the length of the connecting portion 201 can be small. In order to ensure that the second crimping portion 202 can contact the capacitor 6, the length of the second crimping portion 202 needs to be lengthened. Therefore, it is preferred that the matching hole 5 is inserted from the end where the connecting portion 201 is located. At this time, the width of the connecting portion 201 needs to be smaller than the length of the matching hole 5. The length of the matching hole 5 refers to the long side dimension of the cross section of the matching hole 5. The length direction of the matching hole 5 is parallel to the width direction of the connecting portion 201. In this matching structure, the connecting portion 201 and the second crimping portion 202 can be straight plates or curved plates, as long as they are not in the same plane. The length of the second crimping portion 202 is preferably greater than the length of the connecting portion 201 .

[0053] The second coordination structure: Figure 3 As shown, after the fixed part 1 and the movable part 2 fix the capacitor 6, the matching hole 5 is stuck on the connecting part 201, and there is an extension plate 2011 between the position of the matching hole 5 and the connection between the connecting part 201 and the second crimping part 202, and the capacitor 6 is clamped in the polygonal space b formed by the first crimping part 102, the extension plate 2011 and the second crimping part 202. The extension plate 2011 is a part of the connecting part 201, and the length of the connecting part 201 is relatively long at this time, and the length of the connecting part 201 is preferably greater than the length of the second crimping part 202. Under this matching structure, the connecting part 201 and the second crimping part 202 can be a straight plate or an arc plate, and the connecting part 201 and the second crimping part 202 can also be in the same plane, that is, the movable part 2 is a straight plate.

[0054] Since the fixed part 1 and the movable part 2 are not absolutely fixed at the matching hole 5, the insertion depth of the two parts can be adaptively adjusted according to the size of the capacitor 6 to achieve a force balance state.

[0055] When the fixing member 1 and the movable member 2 are both L-shaped folded plates, preferably, the angles between the fixing portion 101 and the first crimping portion 102 and between the connecting portion 201 and the second crimping portion 202 are all obtuse angles, and further preferably, the angles are no greater than 120°.

[0056] like Figure 8 As shown, a fixing hole 7 is provided on the fixing portion 101 , the first crimping portion 102 is located at one end of the fixing portion 101 in the length direction, and the length direction of the matching hole 5 is parallel to the width direction of the first crimping portion 102 .

[0057] In a preferred embodiment of the present invention, the structure of the movable part 2 is the same as that of the fixed part 1, so that batch production can be achieved by using only one mold.

[0058] When the movable part 2 has the same structure as the fixed part 1, Fig. 9 As shown, both include a first panel 10 and a second panel 11, the first panel 10 is provided with a fixing hole 7, the matching hole 5 is located on the second panel 11, and an obtuse angle is formed between the first panel 10 and the second panel 11. On the fixing member 1, the first panel 10 serves as a fixing portion 101, and the second panel 11 serves as a first crimping portion 102. The movable member 2 can select the first panel 10 or the second panel 11 to be connected to the second panel 11 of the fixing member 1 according to different assembly methods.

[0059] In order to ensure that the movable part 2 can pass through the matching hole 5 of the fixing part 1 in any assembly mode, it is necessary to limit the width of the first panel 10 and the second panel 11. The specific structure is as follows: Fig. 9 As shown, the second panel 11 includes a narrow section 8 and a wide section 9 located at one end of the narrow section 8, the first panel 10 is located at the other end of the narrow section 8, the matching hole 5 is located on the wide section 9, the length direction of the matching hole 5 is parallel to the width direction of the second panel 11, and the widths of the narrow section 8 and the first panel 10 are both smaller than the length of the matching hole 5.

[0060] During installation, the capacitor 6 is placed at a suitable position, the first panel 10 of the fixing member 1 is positioned on the terminal 3 by means of the fastening screws 4 (the fastening screws 4 are not tightened), and then the matching mode of the movable member 2 is selected according to the size of the capacitor 6 .

[0061] When the capacitor 6 is smaller in size, the first matching method is selected. In this case, the first panel 10 of the movable member 2 is the connecting portion 201, and the second panel 11 of the movable member 2 is the second crimping portion 202. Fig.10 As shown, the first panel 10 of the movable member 2 is inserted upwardly through the matching hole 5 of the fixing member 1 in the lower right direction. At this time, the first panel 10 of the movable member 2 contacts the second crimping portion 202 of the fixing member 1, and the second panel 11 of the movable member 2 is located in a downward posture on the right side. The insertion depth of the first panel 10 of the movable member 2 is adjusted so that the second panel 11 of the movable member 2 contacts the capacitor 6, and then the fastening screw 4 is tightened. At this time, the capacitor 6 is fixed by the three-point cooperation of the junction box, the second panel 11 of the fixing member 1 and the second panel 11 of the movable member 2 (i.e. Figure 3 At this time, the first panel 10 of the movable member 2 and the second panel 11 of the fixed member 1 form an approximately triangular space a.

[0062] When the capacitor 6 is larger in size, the second matching method is selected. In this case, the second panel 11 of the movable member 2 is the connecting portion 201, and the first panel 10 of the movable member 2 is the second crimping portion 202. Fig.11 As shown, the first panel 10 of the movable part 2 is inserted downward through the upper left of the matching hole 5 of the fixed part 1. At this time, the second panel 11 of the movable part 2 is in contact with the second panel 11 of the fixed part 1, and the first panel 10 of the movable part 2 is located in a downward posture on the right side. The first panel 10 of the movable part 2 is made to contact with the capacitor 6 by adjusting the insertion depth of the second panel 11 of the movable part 2, and then the fastening screw 4 is tightened. At this time, the capacitor 6 is fixed by the three-point matching of the junction box, the first panel 10 of the movable part 2 and the first panel 10 of the fixed part 1. At this time, the extension plate 2011 of the movable part 2 is located at the right end of the second panel 11, and the first panel 10 of the movable part 2, the extension plate 2011 of the movable part 2 and the second panel 11 of the fixed part 1 form an approximately polygonal space b.

[0063] In the above two matching modes, by inserting the second panel 11 (or the first panel 10) of the movable member 2 into the matching hole 5 of the fixing member 1 at different positions, capacitors 6 of different specifications can be fixed. In addition, the fixing hole 7 is a strip hole, and the length direction of the fixing hole 7 is parallel to the length direction of the fixing part 101, so that the fixing position of the fixing member 1 can be adjusted, and capacitors 6 of more specifications can be fixed by matching.

[0064] In a preferred embodiment, the width of the wide section 9 is 1.2 to 1.5 times the width of the first panel 10 .

[0065] The utility model also proposes a junction box, including a box body 12, a capacitor 6, a terminal 3 and the motor capacitor mounting clamp mentioned above, the capacitor 6 is placed in the box body 12, the fixing part 101 of the motor capacitor mounting clamp is connected to the terminal 3, and the fixing part 1 and the movable part 2 are pressed on the outer surface of the capacitor 6.
