Description

Technical Field

[0001] This utility model belongs to the field of bus trunking technology, specifically, it relates to a bus trunking connector assembly with electromagnetic shielding function. Background Technology

[0002] Busbar trunking is a busbar system consisting of a metal plate (steel or aluminum plate) as a protective shell, conductive bars, insulating materials, and related accessories. It can be made into standard length sections with plug-in junction boxes at intervals, or it can be made into a feeder-type enclosed busbar without junction boxes in the middle, and it is an AC three-phase four-wire or five-wire system.

[0003] Some existing busbar connector assemblies with electromagnetic shielding functions have unreasonable shielding structure designs, making the installation of the electromagnetic shielding shell cumbersome and inconvenient. This makes disassembly and assembly troublesome and inconvenient for maintenance personnel when inspecting the internal parts of the connector.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] To address the technical problems of existing busbar connector assemblies with electromagnetic shielding, such as unreasonable shielding structure design, cumbersome and inconvenient installation of the electromagnetic shielding shell, and difficulties in disassembly and assembly for subsequent internal maintenance, the basic concept of this utility model is as follows:

[0006] A busbar trunking connector assembly with electromagnetic shielding function includes a busbar trunking housing and a connector body connected to one side of the busbar trunking housing. The busbar trunking housing is equipped with a shielding disassembly and assembly mechanism and a limiting mechanism.

[0007] The shielding assembly and disassembly mechanism includes a first shielding plate disposed on the busbar housing, and a second shielding plate connected to the first shielding plate. The first shielding plate and the second shielding plate are used to cover the outside of the connector body, thereby reducing external electromagnetic interference.

[0008] The limiting mechanism includes a limiting strip connected to the inner outer wall of the first shielding plate. The limiting strip is used to limit the lateral installation of the first shielding plate and the second shielding plate, thereby improving installation stability.

[0009] In a preferred embodiment of the present invention, the shielding assembly / disassembly mechanism includes a conductive copper busbar connected to one side of the outer wall of the busbar housing, a rotating shaft connected to the top surface of the first shielding plate, one side of the rotating shaft being rotatably mounted on one side of the outer wall of the second shielding plate, and an insert plate connected to one bottom outer wall of the first shielding plate.

[0010] In a preferred embodiment of the present invention, the limiting mechanism includes a limiting plate connected to the outer wall of the busbar housing, the outer wall of the limiting plate having a limiting groove, and the outer wall of the limiting strip being inserted into the inner wall of the limiting groove.

[0011] In a preferred embodiment of this utility model, a sliding sleeve is connected to one outer wall of the first shielding plate, a spring is connected to the inner wall of the sliding sleeve, a positioning rod is connected to the end of the spring away from the sliding sleeve, a retaining sleeve is connected to the other outer wall of the first shielding plate, a positioning hole is opened on one side of the outer wall of the retaining sleeve, the outer wall of the positioning rod is engaged with the inner wall of the positioning hole, and a lever is connected to the outer wall of the positioning rod.

[0012] In a preferred embodiment of this utility model, the outer wall of the positioning rod is fitted to the inner wall of the positioning hole.

[0013] In a preferred embodiment of this utility model, the number of limiting plates is four, and the limiting plates are distributed in a symmetrical structure in pairs on the outer walls of the two busbar trough shells.

[0014] In a preferred embodiment of this utility model, a connecting slot is provided on the outer wall of the other side of the first shielding plate, and the outer wall of the insert plate is inserted into the inner wall of the connecting slot. The insert plate is made of rubber.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] This invention involves rotating the first shielding plates on both sides downwards via a rotating shaft, thereby driving the insert plate to complete the initial connection and installation of the two first shielding plates. Then, by moving the lever, the positioning insert rod retracts into the sliding sleeve. When the first shielding plates on both sides drive the sliding sleeve and the retaining sleeve to the same horizontal line, releasing the lever allows the spring to return and reset the positioning insert rod, thus inserting it into the positioning hole to complete the installation. This installation method does not require the use of external tools and can quickly complete the assembly and disassembly.

[0017] This invention uses a first shielding plate to move a limiting strip closer to a limiting plate, then moves a second shielding plate to move the limiting strip so that it aligns with a limiting groove. After that, the first shielding plate moves the limiting strip into the limiting groove. The limiting strip and the limiting groove together provide lateral limiting for the first and second shielding plates, thereby improving installation stability and shielding effect.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] like Figures 1 to 5 As shown, a busbar trunking connector assembly with electromagnetic shielding function includes a busbar trunking housing 1 and a connector body 2 connected to one side of the busbar trunking housing 1. A shielding disassembly and assembly mechanism 31 and a limiting mechanism 32 are installed on the busbar trunking housing 1. The shielding disassembly and assembly mechanism 31 includes a first shielding plate 312 disposed on the busbar trunking housing 1, and a second shielding plate 314 connected to the first shielding plate 312. The first shielding plate 312 and the second shielding plate 314 are used to cover the outside of the connector body 2, thereby reducing external electromagnetic interference. The limiting mechanism 32 includes a limiting strip 323 connected to the inner outer wall of the first shielding plate 312. The limiting strip 323 is used to laterally limit the installation of the first shielding plate 312 and the second shielding plate 314, thereby improving installation stability.

[0028] Furthermore, the shielding assembly / disassembly mechanism 31 includes a conductive copper busbar 311 connected to one side of the outer wall of the busbar housing 1, a rotating shaft 313 connected to the top surface of the first shielding plate 312, one side of the rotating shaft 313 being rotatably mounted on one side of the outer wall of the second shielding plate 314, and one bottom outer wall of the first shielding plate 312 being connected to an insert plate 315.

[0029] Furthermore, a sliding sleeve 316 is connected to one of the outer walls of the first shielding plate 312, and a spring 317 is connected to the inner wall of the sliding sleeve 316. A positioning rod 318 is connected to the end of the spring 317 away from the sliding sleeve 316. A retaining sleeve 319 is connected to the other outer wall of the first shielding plate 312. A positioning hole 3110 is opened on one side of the outer wall of the retaining sleeve 319. The outer wall of the positioning rod 318 is engaged with the inner wall of the positioning hole 3110. A lever 3111 is connected to the outer wall of the positioning rod 318.

[0030] Furthermore, the outer wall of the positioning rod 318 fits snugly against the inner wall of the positioning hole 3110. A connecting slot is provided on the outer wall of the other side of the first shielding plate 312. The outer wall of the insert plate 315 is inserted into the inner wall of the connecting slot. The insert plate 315 is made of rubber, which improves the stability of the positioning rod 318 being engaged with the inner wall of the positioning hole 3110.

[0031] The limiting mechanism 32 includes a limiting plate 321 connected to the outer wall of the busbar housing 1. A limiting groove 322 is formed on the outer wall of the limiting plate 321, and the outer wall of the limiting strip 323 is inserted into the inner wall of the limiting groove 322.

[0032] Furthermore, there are four limiting plates 321, which are symmetrically distributed in pairs on the outer walls of the two busbar housings 1. This allows for lateral locking and limiting of the left and right sides of a single first shielding plate 312, thereby improving the installation stability of the two shielding plates.

[0033] The implementation principle of a busbar connector assembly with electromagnetic shielding function in this embodiment is as follows: A first shielding plate 312 and a second shielding plate 314 are installed on the two sides of the busbar housing 1 and then covered outside the connector body 2, thereby providing electromagnetic shielding through the first shielding plate 312 and the second shielding plate 314. When installing the first shielding plate 312 and the second shielding plate 314, firstly, the first shielding plate 312 on both sides is moved so that it rotates upwards through the rotation between the pivot 313 and the second shielding plate 314, thus unfolding the assembly. Then, the bottom end of the second shielding plate 314 is placed against the top of the two sides of the busbar housing 1. Simultaneously, the position of the second shielding plate 314 is adjusted, and then the limiting mechanism 32 limits the second shielding plate 314 to a position directly above the connector body 2. Then, the first shielding plate 312 is moved closer together, and then... Insert plate 315 is inserted into the slot on the outer wall of another first shielding plate 312, thus completing the initial installation connection. At this time, the lever 3111 can be moved to move the positioning rod 318 to the left, while the spring 317 is compressed during the movement. At this time, the outer wall of the positioning rod 318 will disengage from the inner wall of the positioning hole 3110 on the sleeve 319. Then, the first shielding plates 312 on both sides are moved again to make the sliding sleeve 316 and the sleeve 319 on the same horizontal line, and then released. The opening plate 3111, through the spring 317, can drive the outer wall of the positioning rod 318 to be inserted into the positioning hole 3110, thereby completing the limiting of the first shielding plates 312 on both sides. This completes the installation of the first shielding plate 312 and the second shielding plate 314. When disassembling, simply move the positioning rod 318 out of the inner wall of the positioning hole 3110 and then move the first shielding plates 312 on both sides to rotate outward to complete the disassembly. This installation method does not require the use of external tools and can quickly complete the assembly and disassembly.

[0034] After placing the second shielding plate 314 on the busbar housing 1, the first shielding plates 312 on both sides are rotated, causing the first shielding plate 312 to drive the limiting strip 323 to rotate downwards, thus gradually approaching the limiting plate 321. Then, the position of the second shielding plate 314 is adjusted to make the limiting strip 323 correspond to the position of the limiting groove 322. After that, the first shielding plate 312 drives the limiting strip 323 to be inserted into the inner wall of the limiting groove 322. In this way, the lateral position of the first shielding plate 312 and the second shielding plate 314 can be limited, thereby improving the stability after installation and thus improving the shielding effect.
