Description

Technical Field

[0001] This utility model relates to the field of busbar trunking terminal protection technology, specifically a snap-fit ​​busbar trunking terminal end cap structure. Background Technology

[0002] The busbar trunking terminal end cap structure, also known as the busbar trunking terminal cover, is an end protection device in the busbar trunking system. It is mainly used to seal the terminal part of the busbar trunking to prevent dust, moisture, and debris from entering the busbar trunking, and is an important part to ensure the stability and safety of electrical connections.

[0003] Existing busbar trunking end caps are mostly installed using screw fixing. The edge or interior of the end cap has flanges or fixing holes, and corresponding mounting holes are provided at the end of the busbar trunking shell. When connecting the end cap to the busbar trunking, bolts are first passed through these holes, and then nuts are used for tightening. The entire process is complex, requires auxiliary tools, and is inconvenient to disassemble. Especially during busbar trunking expansion or maintenance, the bolt fixing method affects the disassembly speed of the end caps, thus reducing overall work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a snap-fit ​​busbar trunking terminal end cap structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A snap-fit ​​busbar trunking terminal end cap structure includes: a terminal cover, which is detachably connected to the busbar trunking housing and can protect the end of the busbar trunking;

[0007] The terminal cover has an installation groove inside, and a connecting component is provided in the installation groove. The connecting component includes an elastic element provided in the installation groove. As the terminal cover moves closer to the busbar housing, the elastic element cooperates with the fitting groove provided on the busbar housing, so that the terminal cover is fixedly connected to the busbar housing.

[0008] The terminal cover is also provided with an unlocking structure. As the unlocking structure moves toward the outside of the busbar housing, the unlocking structure can drive the elastic element to separate from the fitting groove.

[0009] As described above, the snap-fit ​​busbar trunking terminal end cap structure includes a connecting component comprising a fixed rod disposed within the mounting groove, two sets of elastic elements being provided, the two sets of elastic elements being symmetrically slidably disposed on the fixed rod, and two sets of springs being symmetrically sleeved on the fixed rod, one end of the spring abutting against a baffle formed on the fixed rod, and the other end abutting against an elastic element slidably disposed on the fixed rod.

[0010] As described above, the snap-fit ​​busbar trunking terminal end cap structure includes an elastic element comprising a lifting sleeve slidably disposed on the fixed rod, a locking rod disposed on the lifting sleeve, and the locking rod slidably disposed within the fitting groove.

[0011] As described above, the snap-fit ​​busbar trunking terminal end cap structure includes a locking groove and an open groove formed on the side wall of the busbar trunking housing.

[0012] As described above, the snap-fit ​​busbar trunking terminal end cap structure includes an unlocking structure comprising a linkage component and an unlocking component. The linkage component includes a slide rod disposed in the mounting groove, and a sleeve ring is slidably disposed on the slide rod. The sleeve ring is connected to two sets of lifting sleeves respectively through two sets of hinge rods.

[0013] As described above, the snap-fit ​​busbar trunking terminal end cap structure includes an unlocking plate that is slidably disposed on the terminal cover. The unlocking plate is fixedly connected to the sleeve ring via a connecting rod, and an auxiliary groove is also provided on the unlocking plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By setting up a connection component and utilizing the fit between the elastic element and the fitting groove, a quick connection between the terminal cover and the busbar housing can be achieved. The entire process does not require the use of bolts or other additional tools, making the operation simple and quick.

[0016] Meanwhile, by setting up an unlocking structure, when it is necessary to disassemble the terminal cover, simply pry open the auxiliary groove inside and pull the unlocking plate outward to quickly separate the locking rod from the locking groove, thereby separating the terminal cover from the busbar housing. The operation process is simple and efficient, making it convenient for operators to expand or maintain the busbar. Attached Figure Description

Detailed Implementation

[0023] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0024] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0025] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0026] Please see Figures 1-5 In this embodiment of the utility model, a snap-fit ​​busbar trunking terminal end cap structure includes:

[0027] Terminal cover 2, which is detachably connected to busbar housing 1, can protect the end of the busbar.

[0028] The terminal cover 2 has an installation groove 202 inside, and a connecting component is provided in the installation groove 202. The connecting component includes an elastic element provided in the installation groove 202. As the terminal cover 2 moves closer to the busbar housing 1, the elastic element cooperates with the fitting groove provided on the busbar housing 1, so that the terminal cover 2 is fixedly connected to the busbar housing 1.

[0029] Preferably, please refer to Figure 3 , Figure 4 The terminal cover 2 has mounting slots 202 on both the left and right inner walls. Each mounting slot 202 has a connecting component. The two sets of connecting components work together to achieve a stable connection between the terminal cover 2 and the busbar housing 1, thereby providing stable protection for the end of the busbar.

[0030] In particular, please see Figure 3 The end of the terminal cover 2 connected to the busbar housing 1 has a guide slope 203 with a large curvature. During the connection process between the terminal cover 2 and the busbar housing 1, the guide slope 203 cooperates with the edge of the busbar housing 1, which can quickly guide the terminal cover 2 and the busbar housing 1 to the state of axial overlap, thereby improving the connection speed between the terminal cover 2 and the busbar housing 1.

[0031] For details, please refer to Figure 3 , Figure 4 , Figure 5 The connecting assembly includes a fixed rod 5 disposed in the mounting groove 202. Two sets of elastic elements are provided, and the two sets of elastic elements are symmetrically slidably disposed on the fixed rod 5. Two sets of springs 12 are symmetrically sleeved on the fixed rod 5. One end of the spring 12 abuts against the baffle 502 formed on the fixed rod 5, and the other end abuts against the elastic element slidably disposed on the fixed rod 5.

[0032] The elastic element includes a lifting sleeve 6 slidably disposed on the fixed rod 5, and a locking rod 10 is provided on the lifting sleeve 6. The locking rod 10 is slidably disposed in the fitting groove.

[0033] Preferably, please refer to Figure 5 A slider 601 is formed on the inner wall of the lifting sleeve 6. The slider 601 is slidably disposed in the groove 501 opened on the outer wall of the fixed rod 5. With the cooperation of the slider 601 and the groove 501, the lifting sleeve 6 can only slide along the axial direction of the fixed rod 5.

[0034] The fitting groove includes a locking groove 4 and an open groove 401 formed on the side wall of the busbar housing 1;

[0035] Specifically, the two sets of springs 12 are exactly the same, and the springs 12 are always in a compressed state, pushing the lifting sleeve 6 to move away from the baffle 502.

[0036] Initially, the two sets of lifting sleeves 6 are far apart. During the docking process between the terminal cover 2 and the busbar housing 1, the locking rod 10 will first contact the open groove 401. Due to the inward contraction of the open groove 401, as the terminal cover 2 moves toward the busbar housing 1, the two sets of lifting sleeves 6 move toward the baffle 502 simultaneously, further compressing the spring 12. When the locking rod 10 separates from the open groove 401 and engages with the locking groove 4, the spring 12 quickly releases its elastic potential energy to push the two sets of lifting sleeves 6 away from each other, so that the two sets of locking rods 10 move to both ends of the locking groove 4. At this time, the locking rod 10 is stuck in the locking groove 4, and the groove wall of the locking groove 4 blocks the locking rod 10, thereby achieving a fixed connection between the terminal cover 2 and the busbar housing 1. The whole process does not require the use of bolts for fixing, and the operation is simple and quick.

[0037] Further, please refer to Figure 1 , Figure 5 The terminal cover 2 is also provided with an unlocking structure. During the process of the unlocking structure moving toward the outside of the busbar housing 1, the unlocking structure can drive the elastic element to separate from the fitting groove.

[0038] The unlocking structure includes a linkage component and an unlocking component. The linkage component includes a slide rod 7 disposed in the mounting groove 202. A sleeve ring 11 is slidably disposed on the slide rod 7. The sleeve ring 11 is connected to two sets of lifting sleeves 6 respectively through two sets of hinge rods 9.

[0039] The unlocking component includes an unlocking plate 3 that is slidably disposed on the terminal cover 2. The unlocking plate 3 is fixedly connected to the sleeve ring 11 via a connecting rod 8, and an auxiliary groove 301 is also provided on the unlocking plate 3.

[0040] In particular, please see Figure 4 In the initial state, due to the elastic potential energy stored in the spring 12 and the connection of the hinge rod 9, the sleeve ring 11 pulls the unlocking plate 3 close to the fixed rod 5. At this time, the unlocking plate 3 is embedded in the terminal cover 2, and the terminal cover 2 is provided with a groove 201. The groove 201 can expose the auxiliary groove 301 on the unlocking plate 3, so that the operator can pull the unlocking plate 3 outward to drive the locking rod 10 to separate from the fitting groove.

[0041] In conjunction with the above, during the connection between the terminal cover 2 and the busbar housing 1, the lifting sleeves 6, which are close to each other, will push the sleeve ring 11 to move the unlocking plate 3 along the axial direction of the slide rod 7 away from the fixed rod 5 under the connection of the hinge rod 9, so that the unlocking plate 3 protrudes from the terminal cover 2; during the subsequent process of the locking rod 10 being engaged with the end of the locking groove 4, the lifting sleeve 6 can drive the sleeve ring 11 to pull the unlocking plate 3 back to the initial state of being engaged with the terminal cover 2, preventing the terminal cover 2 from separating from the busbar housing 1 due to accidental contact during use.

[0042] When it is necessary to expand the busbar trunking, first fix the busbar trunking housing 1, then first hold the auxiliary groove 301, and then pull the unlocking plate 3 outward; then, the unlocking plate 3 first pulls the sleeve ring 11 away from the fixing rod 5. During this process, under the connection of the hinge rod 9, the sleeve ring 11 pulls the two sets of lifting sleeves 6 closer to each other, so that the locking rod 10 slides in the locking groove 4 until the locking rod 10 is separated from the locking groove 4. With the continued pulling of the unlocking plate 3, the locking rod 10 engages with the open groove 401. At this time, the lifting sleeve 6 is reset, and the terminal cover 2 is separated from the busbar trunking housing 1. The disassembly process is simple and convenient for operators to carry out the expansion operation of the busbar trunking, thereby effectively improving the disassembly and assembly efficiency.
