Description

Technical Field

[0001] The utility model relates to the technical field of capacitor fixed installation, in particular to a capacitor mounting bracket. Background Art

[0002] Generally, a capacitor body is installed and fixedly connected to other installation object parts (such as an electrical installation box) by means of a capacitor mounting bracket. The existing capacitor mounting brackets generally include two interconnected structural parts, namely a connecting part and a mounting part. The connecting part is a structural part for connecting the mounting bracket and the capacitor body, while the mounting part is a structural part for connecting the mounting bracket and other installation object parts (such as an electrical installation box). First, the mounting bracket is connected to the capacitor body through the connecting part, and then the mounting bracket is installed and connected to other installation object parts through the mounting part, thereby realizing the fixed connection between the capacitor body and other installation object parts.

[0003] In the prior art, a capacitor mounting bracket is disclosed, as Figure 1-2 shown. The mounting bracket includes a plastic hanging part body 1, and the plastic hanging part body 1 includes a connecting part 11 and a mounting part 12 which are interconnected.

[0004] Specifically, as Figure 1-2 shown, in the plastic hanging part body 1, the mounting part 12 is a structure of a mounting clip, and the mounting clip is composed of an outer clip 121 and an inner clip 122; the connecting part 11 is a bottom plate provided with a screw hole. During installation, the stud at the bottom of the capacitor metal shell is screwed into the screw hole to realize the fixed connection between the hanging part body 1 and the capacitor metal shell 3, and a capacitor with quick installation can be formed. When installing the capacitor, the outer clip 121 is aligned with the hanging hole or hanging groove provided on the installation object part 2, and the capacitor can be quickly installed.

[0005] However, in the structure of the above capacitor mounting bracket, the aperture of the screw hole on the connecting part 11 is fixed and cannot be expanded when the hanging part body 1 is installed on the capacitor metal shell 3. This results in that when manually assembling the hanging part body 1 and the capacitor metal shell 3, the stud must be accurately aligned with the screw hole and the alignment angle must be maintained before the stud is screwed into the screw hole, and the operation requirements are relatively high.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0035] The present invention provides a capacitor mounting bracket, which can be used to mount and connect a capacitor body to other mounting object parts (such as an electrical installation box), and adopts a structure of a threaded sleeve composed of three-piece threaded members. During the assembly process of the threaded sleeve and the stud on the capacitor body, the aperture of the threaded hole provided in the threaded sleeve can be expanded, making the connection operation between the mounting bracket and the capacitor body simpler.

[0036] Embodiment 1

[0037] As Figure 3-4 shown, it is the structure of a capacitor mounting bracket in the present invention, that is, the structure of the plastic mounting bracket 5. The plastic mounting bracket 5 is a plastic part integrally injection-molded. The plastic mounting bracket 5 includes two interconnected structural parts, namely a connecting part and a mounting part. The connecting part is a structural part for realizing the connection between the mounting bracket and the capacitor body, and the mounting part is a structural part for realizing the connection between the mounting bracket and other mounting object parts (such as an electrical installation box).

[0038] In Embodiment 1, the connecting part includes a bottom plate 53 and a threaded sleeve composed of three-piece threaded members 54; a through hole 531 penetrating up and down is provided on the bottom plate 53; the threaded sleeve is connected to the lower end of the bottom plate 53; a threaded connection hole is provided in the threaded sleeve below the through hole 531, and there is a partition gap 533 between adjacent two threaded members 54.

[0039] There is a connecting part between the threaded member 54 and the bottom plate 53, and through holes 532 penetrating up and down are provided on the bottom plate 53 between adjacent two connecting parts; the three through holes 532 are radially distributed around the outer circle of the through hole 531 and are connected to the through hole 531; the upper end of the partition gap 533 is connected to the through hole 532.

[0040] As Figure 4 shown, the inner wall of the three-piece threaded member 54 is provided with threads, jointly forming a threaded connection hole, which is directly below the through hole 531. On the bottom plate 53, one through hole 531 and three through holes 532 are all connected, jointly forming a hole in a shape similar to the letter "Y" as a whole.

[0041] The mounting bracket is made of plastic, and because plastic is inherently elastic, when pressure is applied to perforation 531 during stud installation, the size of through-hole 532 changes accordingly, allowing the opening of perforation 531 to expand, making it easier to insert the stud. Once the stud is inserted into the threaded hole, the threaded sleeve expands outward under the pressure, expanding the diameter of the threaded hole. This makes it easier for the stud to enter the threaded hole, simplifying installation.

[0042] At the same time, if Figure 3 、 4 As shown, two adjacent threaded members 54 are separated and disconnected by a partition gap 533. The upper end of the partition gap 533 communicates with the through-hole 532, and a connection portion is provided between the threaded member 54 and the base plate 53. In this embodiment, the connection portion is located between the two through-holes 532. When the through-hole 531 expands outward, the threaded member 54 connected to the base plate 53 is also driven to expand outward.

[0043] At the same time, if Figure 3 、 4 As shown, in this embodiment 1, the upper end of each partition gap 533 is connected to a through hole 532, thereby achieving a structure in which the partition gap 533, the through hole 532, the threaded connection hole, and the through hole 531 are connected. During the insertion of the stud, the through hole 531 and the threaded mounting hole can both achieve installation expansion of the aperture.

[0044] At the same time, in this embodiment, a reinforcing rib 541 is provided between the outer wall of the threaded member 54 and the lower end of the base plate 53, which can be used to effectively control the outward expansion of the threaded member 54, and thus control the expansion of the threaded connection hole when the stud is installed.

[0045] Preferably, in the first embodiment, the mounting member for connecting the mounting bracket to other mounting objects is connected to the upper end of the bottom plate 53 .

[0046] like Figure 3 、 4 As shown, the mounting member includes an intermediate connecting plate 52 connected to the upper end of the bottom plate 53, a top plate 51 connected to the upper end of the intermediate connecting plate 52, a buckle 55 connected to the lower end of the top plate 51, and a bayonet member 56 connected to the upper end of the top plate 51.

[0047] In this embodiment, the buckle 55 is a plug buckle structure, and is a male buckle in the plug buckle. Inserting it into the female buckle provided on the installation object can realize the connection between the mounting bracket and the installation object. Figure 3 As shown, the buckle 55 is a longitudinally extending male buckle, which can be inserted downward into the female buckle during installation.

[0048] The bayonet member 56 is provided at the upper end of the top plate 51, and a bayonet 561 that penetrates through both lateral ends and has an upward opening is provided on the bayonet member 56. During installation, the clamping portion on the installation object member can be snapped into the bayonet 561 to realize the connection between the installation bracket and the installation object member.

[0049] As Figure 3 shown, in the first embodiment, the bayonet member 56 is vertically connected to the upper end surface of the top plate 51. The bayonet 561 penetrates through both the left and right ends and has an upward opening. The front and rear side walls and the left and right side walls of the bayonet member 56 are mutually parallel planar shapes, and the combination of the bayonet member 56 and the bayonet 561 as a whole has a square sheet-like structure. At the same time, as Figure 3 shown, arc transition sections 562 extending outward are also provided between the left and right side walls of the bayonet member 56 and the upper end of the top plate 51. Compared with the structure where the left and right side walls and the upper end of the top plate 51 are at right angles, the structure of the arc transition section 562 as Figure 3 shown can increase the connection area between the left and right side walls of the bayonet member 56 and the upper end of the top plate 51, and further enhance the connection strength between the left and right side walls of the bayonet member 56 and the upper end of the top plate 51.

[0050] At the same time, in this embodiment, the combination of the bayonet member 56 and the bayonet 561 as a whole has a square sheet-like structure. Compared with the scheme where the combination of the bayonet member 56 and the bayonet 561 as a whole has a circular sheet-like structure, on the premise that the outer contour length, outer contour thickness, outer contour height of the bayonet member 56 and the size of the bayonet 561 are the same, the volume of the bayonet member 56 in the square sheet-like structure scheme is larger (in the plastic installation bracket 5 formed by integral injection molding, for example, there is relatively more plastic remaining between the inner wall of the bayonet 561 and the outer wall of the bayonet member 56), and thus the strength of the bayonet member 56 in the square sheet-like structure scheme is better.

[0051] Through the settings of the buckle 55 and the bayonet 561, it is possible to realize the installation connection with two different installation parts on the installation object member at the same time, thereby realizing the installation connection at two points and better enhancing the connection strength between the installation bracket and the installation object member. Of course, in the installation bracket, the buckle 55 and the bayonet 561 can be set at the same time or separately.

[0052] In this embodiment, the three through holes 532 are evenly distributed along the radial direction of the through hole 531; the three-lobe threaded members 54 are evenly distributed along the radial direction. When pressed, each threaded member 54 is more evenly stressed, which is beneficial to the uniform expansion of the threaded connection hole in three directions. Compared with the structure of the threaded sleeve composed of two-lobe threaded members, the threaded sleeve composed of three-lobe threaded members has better expansibility and can better realize the expansion of the aperture of the threaded connection hole during installation operation.

[0053] Embodiment Two

[0054] Based on Embodiment 1, we adjusted the connection method of the buckle 55 to form the structure of Embodiment 2 as shown in Figure 5-6 The difference from Embodiment 1 is that we connect the buckle 55 to the middle connecting plate 52 instead of connecting it to the lower end of the top plate 51. In Embodiment 2, the buckle 55 extends horizontally and can be inserted horizontally into the female buckle during installation.

[0055] Figure 7 is the usage state diagram of the capacitor mounting bracket, showing the assembly structure between the capacitor mounting bracket and the metal shell 3 of the capacitor.
