Technical Field

[0001] The utility model relates to the technical field of connection bars, in particular to a connection bar for multiple cables. Background Art

[0002] The connection bar is a junction device for indoor electrical equipment. It is an intermediary component between the wires and electrical equipment. Its role is to provide a safe, reliable and centralized connection point, so that multiple circuit lines can be easily connected into an integrated circuit system. In addition, the connection bar also has the functions of isolating circuits, preventing leakage, and maintaining circuit stability. In practical applications, it is usually widely used in home distribution boxes, cabinets, industrial control cabinets and other occasions.

[0003] The existing multi-cable connection row usually adopts a simple plug-in connection method, which is not fast enough and is prone to loose connection when affected by external forces such as dragging.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a connection bar for multiple cables is proposed. Utility Model Content

[0010] Furthermore, the shielding cover has a "U"-shaped structure, and two shielding covers are symmetrically arranged about the transverse center line of the busbar.

[0011] Furthermore, the protection component also includes a fixed connecting rod and a protective rubber sleeve. The inner side of the shielding cover is connected to the protective rubber sleeve via the fixed connecting rod, and the protective rubber sleeve is an arc-shaped structure.

[0012] The utility model provides a connection bar for multiple cables, which has the following beneficial effects:

[0019] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0020] like Figure 1 and Figure 2 As shown, a connection bar of multiple cables includes a busbar 1, a plug-in bar 4 and a clamping assembly 6. The plug-in bar 4 is installed on one side of the busbar 1, and the plug-in bar 4 and the busbar 1 are provided with clamping assemblies 6 on both sides. The inside of the busbar 1 is provided with plug-in holes 2 at equal distances, and the outside of the plug-in holes 2 is provided with rubber rings 3; the plug-in bar 4 is provided with a wiring terminal on one side close to the plug-in hole 2, and the other side of the plug-in bar 4 is connected with a cable 5;

[0021] The specific operation is as follows: the connection terminal of the socket strip 4 can be connected to the socket hole 2 of the busbar 1. At this time, the rubber ring 3 is arranged on the outside of the connection to play a role in dust and water prevention, thereby realizing the connection of multiple cables.

[0022] like Figure 1 and Figure 3 As shown, the clamping assembly 6 includes a spring 601, an arc-shaped card plate 602, a protrusion 603, an arc-shaped frame 604 and a slot 605. The springs 601 are fixed to the outer walls of the left and right sides of the plug strip 4, and the arc-shaped card plate 602 is fixed to the top of the spring 601, and the protrusion 603 is fixed to the outer middle part of the arc-shaped card plate 602. The left and right sides of the busbar 1 are integrally provided with an arc-shaped frame 604, and the inner wall of the middle part of the arc-shaped frame 604 is provided with a slot 605. The size of the arc-shaped card plate 602 is consistent with that of the arc-shaped frame 604, and the protrusion 603 of the arc-shaped card plate 602 is connected with the slot 605 by snapping;

[0023] The specific operation is as follows: the dimensions of the arc-shaped card plate 602 and the arc-shaped frame 604 match so that the arc-shaped card plates 602 on both sides of the extension strip 4 can be snapped into the arc-shaped frames 604 on both sides of the extension strip 4 under the action of the spring 601, thereby enhancing the tightness of the connection; at the same time, the protrusion 603 of the arc-shaped card plate 602 can be snapped into the card slot 605 of the arc-shaped frame 604, thereby preventing it from loosening, without the need for bolts to tighten; on the contrary, when disassembling, the back pressure causes the arc-shaped card plate 602 to retract under force, thereby disassembling the extension strip 4.

[0024] like Figure 2 and Figure 3As shown, the outer sides of the upper and lower sides of the busbar 1 are both installed with protective components 7, and the protective components 7 include a shaft seat 701, a rotating shaft 702 and a shielding cover 703. The shaft seats 701 are fixed on both sides of the upper and lower sides of the busbar 1, and the rotating shaft 702 is rotatably arranged on the inner side of the shaft seat 701, and the outer side of the rotating shaft 702 is fixed with a shielding cover 703; the shielding cover 703 is in a "U"-shaped structure, and two shielding covers 703 are symmetrically arranged about the transverse center line of the busbar 1; the protective component 7 also includes a fixed connecting rod 704 and a protective rubber sleeve 705, and the inner side of the shielding cover 703 is connected to the protective rubber sleeve 705 through the fixed connecting rod 704, and the protective rubber sleeve 705 is in an arc-shaped structure;

[0025] The specific operation is as follows: the shielding cover 703 is easily rotated by the rotating shaft 702 so that the upper and lower shielding covers 703 with a "U"-shaped structure can be covered on the outside of the socket 4 and the busbar 1 after they are assembled. The shielding cover 703 can prevent electromagnetic interference and play a certain shielding role. At the same time, multiple protective rubber sleeves 705 correspond to the cables 5 of the socket 4, so that the flexible protective rubber sleeves 705 with an arc-shaped structure can be covered on the outside of the cables 5 to protect them respectively, while preventing multiple cables 5 from being entangled with each other.

[0026] In summary, if Figure 1-Figure 3 As shown, when the connection bar of the multi-spliced ​​cables is used, the wiring terminals of the plug strip 4 can be first connected to the plug holes 2 of the busbar 1, thereby realizing the connection of the multi-spliced ​​cables. At this time, the rubber ring 3 is arranged on the outside of the connection to play a role in dust and water prevention. Then, the size of the arc-shaped card plate 602 and the arc-shaped frame 604 is matched so that the arc-shaped card plates 602 on both sides of the plug strip 4 can be snapped into the arc-shaped frames 604 on both sides of the plug strip 4 under the action of the spring 601, thereby enhancing the tightness of the connection. At the same time, the protrusion 603 of the arc-shaped card plate 602 can be snapped into the card slot 605 of the arc-shaped frame 604. It plays a role in preventing loosening, and then the shielding cover 703 can be rotated by the rotating shaft 702 so that the upper and lower "U"-shaped shielding covers 703 can be covered on the outside of the socket strip 4 and the busbar 1 after they are assembled. At this time, the shielding cover 703 can prevent electromagnetic interference and play a certain shielding role. At the same time, multiple protective rubber sleeves 705 correspond to the cables 5 of the socket strip 4, so that the flexible protective rubber sleeves 705 with an arc-shaped structure can be covered on the outside of the cables 5 to protect them respectively, while preventing the multiple cables 5 from being entangled with each other, thus completing the use process of the connecting row of multiple cables.
