Specifically, existing cable shielding at the splitter is connected to the splitter sleeve, with the upper and lower splitter housings compressing the sleeve to achieve shield continuity. This approach suffers from unstable conductivity, with on-resistance values ​​ranging from 10 to 30 mΩ, a wide range.

The outer periphery of the second cable clamp 311 is further provided with a wire pressing barrel 313 for compressing the cable shielding layer. The second cable clamp 311 is a conductive structure.

[0009] In the aforementioned splitter, the transfer terminal is a printed circuit board 304 , which is supported in the lower housing 302 by a second fixing block 306 , and the upper housing 301 presses the printed circuit board 304 by a first fixing block 305 .

[0010] In the aforementioned splitter, the first fixing block 305 and the second fixing block 306 are both provided with positioning grooves on the side facing away from the printed circuit board 304, and the upper shell 301 and the lower shell 302 are provided with positioning protrusions 307 adapted to the positioning grooves.

[0011] The aforementioned splitter also includes a shielding shell, a straight sleeve and a heat shrink tube covering the cable.

[0012] The objectives of the present invention and the technical problems solved therein are also achieved by adopting the following technical solutions. A shielded bus proposed in accordance with the present invention includes a first cable bus 2, one end of which is connected to a connector, and the other end is connected to a first cable bus 4 and at least one first cable branch 5 through a first splitter.

[0021] The cable core wire at the splitter of the present invention passes through a straight sleeve and is welded to the printed circuit board. The cable shield passes through the cable clamp inside the straight sleeve and is turned outward. The cable shield is compressed by a wire crimping barrel. By tightening the tail nut, the cable clamp is forced to contract and clamp the cable, while ensuring electrical continuity between the cable shield and the straight sleeve housing.

[0047] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the shielded bus proposed in accordance with the present invention in combination with the accompanying drawings and preferred embodiments.

[0048] See also Figure 1-5, which is a schematic diagram of the structure of each part of the shielded bus of the present invention. The cable bus includes a connector, the tail of which is connected to the first cable bus 2, the first cable bus 2 is connected to the second cable bus 4 and the first cable branch 5 through the first splitter 3, the second cable bus 4 is connected to the third cable bus and the second cable branch through the second splitter, the third cable bus is connected to the fourth cable bus and the third cable branch through the third splitter... The N-1th cable bus is connected to the Nth cable bus 6 and the N-1th cable branch 7 through the N-1th splitter 10, the Nth cable bus 6 is connected to the N+1th cable bus 8 and the second N cable branch 9 through the Nth splitter 11, the end of the N+1th cable bus 8 is connected to a connector, and the end of each cable branch is also connected to a connector, and is connected to the device through the connector.

[0049] In this embodiment, the connectors connected to the cables are all first connectors 1, which are electrically connected to the corresponding device-end second connectors 2. However, in other embodiments of the present invention, one of the cable-end connector connected to the cable and the corresponding device-end connector is the first connector 1, and the other is the second connector 2. The type of connector at either end can be selected as needed.

[0050] The first connector 1 includes a first outer shell 101, which has external threads on its rear periphery. An attached housing 104 is internally threaded and locked to the first outer shell 101. A bushing 102 is also provided on the rear periphery of the first outer shell 101. This bushing 102 is used to compress and secure the folded cable shield of the first cable assembly 2 to the first outer shell 101, ensuring shield continuity between the two.

[0051] A first cable clamp 103 is further provided at the outer periphery of the rear end of the first outer shell 101. The first cable clamp 103 is located between the first outer shell 101 and the rear attached shell 104. The first cable clamp 103 is pressed on the bushing 102 and can radially contract and compress the outer periphery of the rear cable when the rear attached shell 104 rotates relative to the first outer shell 101 and moves axially forward to achieve threaded locking, thereby achieving a tensile connection between the first connector 1 and the cable.

[0052] In this embodiment, the rear end of the first cable clamp 103 is divided into multiple lobes by a number of axially extending and circumferentially spaced slots, each of which is capable of contracting inward under radial force. The outer periphery of the rear end of the first cable clamp 103 forms a tapered shape with decreasing radial dimensions from front to back. Specifically, the outer periphery of each lobe of the rear end of the first cable clamp 103 forms a gradually inwardly inclined surface from front to back. The inner periphery of the rear attachment housing 104 features a tapered surface that aligns with the tapered surface of the rear end of the first cable clamp 103. This allows the rear end of the first cable clamp 103 to be radially compressed inwardly when the rear attachment housing 104 moves axially forward, causing it to contract and clamp the cable. To further enhance the contact force between the first cable clamp 103 and the cable, the inner periphery of the rear end of the first cable clamp 103 is provided with a number of circumferentially extending and axially spaced grooves.

[0053] In this embodiment, each petal at the rear end of the first cable clamp 103 is cantilevered, and the thickness of the root of each cantilever is much smaller than the thickness of the end thereof, so as to enhance its radial deformation capability.

[0054] In this embodiment, the first cable clamp 103 and the first outer shell 101 also achieve circumferential anti-rotation engagement through a concave-convex structure to prevent cable twisting during assembly. Preferably, the first outer shell 101 is provided with at least one axially extending key 106, and the front circumference of the first cable clamp 103 is provided with a keyway 107 adapted to the key 106. However, in other embodiments, a keyway may be provided on the first outer shell 101, a key may be provided on the front surface of the first cable clamp 103, or other concave-convex structures may be provided to achieve circumferential anti-rotation between the two.

[0055] In this embodiment, a pressure plate 105 is provided on one side of the rear end of the first outer shell 101. This pressure plate 105 is an arc-shaped pressure plate that can be fixed relative to the arc-shaped groove at the rear end of the first outer shell 101 via screws. Together with the arc-shaped groove, it clamps the rear cable, achieving a tensile connection between the first shell 101 and the cable. In other embodiments of the present invention, two pressure plates 105 can be provided opposite each other at the rear end of the first outer shell 101. Both pressure plates 105 are fixed to the first outer shell 101 via screws and compress the rear cable. The bushing 102 presses the cable shielding layer against the outer periphery of the pressure plate 105.

[0056] When the first connector 1 is connected, the cable core wire passes through the tail shell 104, the first cable clamp 103, the bushing 102, and the pressure plate 105 in sequence, enters the first outer shell, and is welded to the contact inside the first outer shell. After passing through the tail shell 104, the first cable clamp 103 and the bushing 102, the cable shielding layer is evenly laid on the pressure plate 105. By tightening the tail shell 104, the bushing 102 presses the cable shielding layer to ensure reliable conduction between the cable shield and the connector shell. At the same time, the first cable clamp contracts and tightens the cable to enhance the cable's resistance to pulling.

[0057] The second connector 12 includes a second outer shell 1201, a tail clip 1202, and a wire crimping sleeve 1203. The tail clip 1202 is locked with the internal thread at the rear of the second outer shell 1201 through its front external thread. The wire crimping sleeve 1203 is threaded and locked to the rear of the tail clip 1202. The cable shielding layer that passes through the wire crimping sleeve 1203 and the tail clip 1202 and connects to the contact piece inside the second outer shell 1201 is turned outward to the outer periphery of the wire crimping sleeve 1203 and is compressed between the wire crimping sleeve 1203 and the tail clip 1202, achieving reliable conduction between the shield and the connector shell. The rear of the wire crimping sleeve 1203 is also provided with a wire crimping structure for performing hexagonal crimping on the rear of the wire crimping sleeve to enhance the cable's resistance to pulling. The first and second outer shells are adapted to plug and maintain shielding conduction.

[0058] The first, second, ..., and Nth splitters have the same structure. Each of these splitters includes a shielding shell, a straight sleeve 303 connected to one end of the shielding shell, and two straight sleeves 303 connected to the other end of the shielding shell. The shielding shell includes an upper shell 301 and a lower shell 302, which snap together to form a circumferentially closed shielding shell. Adapter terminals are fixedly provided within the shielding shell. The straight sleeves at both ends of the shielding shell allow cables to pass through and enter the shielding shell, where they connect to the adapter terminals, enabling the transfer of three cables. In this embodiment, the adapter terminal is a printed circuit board 304, which is positioned and assembled within the shielding shell via a fixing block. In this embodiment, the fixing block comprises two fixing blocks: a first fixing block 305 located between the printed circuit board 304 and the upper shell 301, and a second fixing block 306 located between the printed circuit board 304 and the lower shell 302. The present invention fixes the printed circuit board in the middle of the shielding shell by means of the first fixing block and the second fixing block, thereby preventing the printed circuit board solder joints from being squeezed. At the same time, multiple glue filling processes are unnecessary, and the processing cycle is shortened by four times.

[0059] Preferably, the first fixing block 305 and the second fixing block 306 are both provided with positioning grooves on the side facing away from the printed circuit board 304, and the upper shell 301 and the lower shell 302 are provided with positioning protrusions 307 adapted to the positioning grooves. The positioning protrusions cooperate with the positioning grooves to achieve the coordinated positioning of the upper and lower shells and the fixing blocks, thereby achieving reliable positioning of the printed circuit board 304 clamped between the first fixing block 305 and the second fixing block 306.

[0060] The straight sleeve 303 is provided with an annular groove on its outer circumference at the end where it connects to the shielding housing. Both the upper and lower housings 301 and 302 have arcuate protrusions 308 at positions corresponding to the straight sleeve 303. These arcuate protrusions 308 mate with the annular groove on the outer circumference of the straight sleeve 303. When the upper and lower housings are connected and fixed by screws 310, the arcuate protrusions 308 on the upper and lower housings form an annular protrusion that mates with the corresponding annular groove on the straight sleeve, achieving a tensile-resistant connection between the straight sleeve 303 and the shielding housing. To enhance the seal between the shielding housing and the straight sleeve, a sealing ring can be added to the annular groove to provide a seal between the shielding housing and the straight sleeve.

[0061] In this embodiment, conductive rubber pads 309 are provided between the upper shell 301 and the lower shell 302 and the outer circumferential surface of the straight sleeve 303, and when the upper shell 301 and the lower shell 302 are fixed as a whole, the conductive rubber pads 309 are in a compressed state. Therefore, when the splitter vibrates, the radial gap between the upper and lower shells and the straight sleeve can be absorbed by the conductive rubber pads 309, so that the upper shell 301 and the lower shell 302 always maintain contact and conduction with the straight sleeve 303, thereby ensuring the continuity of the shielding.

[0062] In this embodiment of the present invention, a 0.8 mm gap exists between the upper and lower shells 301, 302, and the outer circumference of the straight sleeve 303. The conductive rubber pad 309 has a thickness of 1 mm. When the conductive rubber pad is placed in the gap between the upper and lower shells 301, 302, and the straight sleeve 303, it compresses to 80% of its original thickness. This creates stable conductivity between the upper and lower shells 301, 302, and the straight sleeve, which are fixed by screws, while also protecting the conductive rubber pad from damage. In this embodiment, the gap between the straight sleeve and the upper and lower shells is formed by an arc-shaped protrusion. Because the radial dimension of the arc-shaped protrusion is greater than the depth of the annular groove on the outer circumference of the straight sleeve, when the two are mated, a gap is formed between the straight sleeve and the shielding shell. By placing the conductive rubber pad within the upper and lower shells of the splitter, this embodiment can reduce the conduction resistance between the splitter bus shield and the splitter shell, achieve reliable conductivity between the straight sleeve and the upper and lower shells of the splitter, ensure continuity between the splitter and the cable shield, and thus achieve continuous shielding of the bus cable. The following table compares the on-resistance of the splitter of the present invention before and after a conductive rubber pad is provided between the shielding shell and the straight sleeve.

[0063] Table 1 On-resistance comparison

[0064]

[0065] In this embodiment, the conductive adhesive extends to a position between the shielding shell and the fixing block, but is not limited thereto.

[0066] The straight sleeve 303 also includes a second cable clamp 311 for compressing the cable. The front end of the second cable clamp 311 is axially blocked by the straight sleeve 301, while the rear end is radially compressed by a tail nut 312 threadedly locked onto the rear end of the straight sleeve 303. When the tail nut 312 is locked in place, the second cable clamp 311 clamps the cable within, achieving a tensile connection between the straight sleeve 303 and the cable at its end. A wire pressing barrel 313 is also provided on the outer periphery of the second cable clamp 311. This wire pressing barrel 313 is used to compress and secure the cable shielding layer against the outer periphery of the wire pressing barrel 313. The second cable clamp 311 is a conductive structure that enables contact and conductivity between the cable shielding layer and the straight sleeve 303, ensuring shielding continuity. The second cable clamp 311 has a similar structure to the first cable clamp, with the tail clamping portion having the same structure as the first cable clamp. The inner periphery of the tail nut also includes a tapered surface for simultaneously compressing the second cable clamp radially and axially to clamp the cable. Preferably, the tail nut and the straight sleeve are sealed by a sealing member.

[0067] When the splitter of the present invention is in use, the upper shell of the shielding shell is opened, and each cable is inserted through the corresponding straight sleeve 303. The core wire is welded to the printed circuit board 304 to realize the cable splitting into two. At the same time, the cable shielding layer passes through the second cable clamp and is turned outward and compressed with a wire pressing barrel to ensure reliable conduction between the shielding and the straight sleeve. Then, the tail nut is tightened to tighten the second cable clamp to tighten the cable. The upper shell is buckled on the lower shell and tightened with screws to complete the splitting. In the splitter of the present invention, an elastic conductive rubber pad is laid between the straight sleeve and the shielding shell. The upper and lower shells, the conductive rubber pad and the straight sleeve are squeezed together with a locking screw to achieve reliable conduction between the straight sleeve and the upper and lower shells, reduce the conduction resistance between the bus shield and the splitter shell, ensure the continuity between the cable shield and the splitter shell, and improve the cable's resistance to pulling.

[0068] In the embodiment of the present invention, the first connector, the second connector and their tail cables are sealed by a double-wall heat shrink tube 13; the splitter and the cable are also sealed by a heat shrink tube, which covers the entire splitter.

[0069] In other embodiments of the present invention, the splitter can realize the splitting of cables into multiple types, that is, one side of the shielding shell of the splitter is connected to a straight sleeve, and the other side is connected to three or more straight sleeves.

[0070] Each cable bus of the present invention can be connected to a cable bus and at least two cable branches through a splitter.

[0071] The shielded bus of the present invention ensures reliable shield continuity between the cable and connector, as well as between the cable and the splitter. The splitter itself also has stable shield continuity, thereby ensuring the shield continuity of the shielded bus. Furthermore, each connection point of the shielded bus of the present invention is equipped with a cable tensile strength structure, which can effectively improve the bus cable's pull resistance, eliminate the glue filling process, shorten the processing cycle, improve production efficiency, and reduce costs.

[0072] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the present profession can make some changes or modifications to equivalent embodiments of equivalent changes using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
