Description

Technical Field

[0001] The utility model relates to the technical field of power lines, in particular to exposed conductive cables. Background Art

[0002] The existing power cord is a conductive cable that can maintain a stable shape after being bent and shaped, as disclosed in patent CN202322639777.X, including a long strip of insulating sheath, a plurality of through-holes arranged separately and parallel to each other in the insulating sheath, a conductor arranged in the through-hole, a flat strip with a cross-section ratio of the long side to the short side greater than 2, the flat strip is a rigid object that can bend around the long side, and a flat strip hole with a cross-section matching the cross-section of the flat strip is provided in the insulating sheath, and the flat strip is connected to the flat strip hole; or, an embedding groove with a cross-section matching the cross-section of the insulating sheath is provided on the side of the long side of the flat strip, and the insulating sheath with the conductor is embedded in the embedding groove. When in use, the conductive needle of the quick-connect connector needs to pierce the insulating sheath and then rest on the conductor. Since the conductive needle is a sharp object with a small area at the sharp end, it needs to be inserted into the conductor to ensure sufficient contact area to ensure smooth power transmission. However, inserting it into the conductor can easily cause damage to the conductor. Summary of the Invention

[0003] The object of the present utility model is to provide an exposed conductive cable which can overcome one or more of the above-mentioned disadvantages and can be connected to a conductor without piercing the insulating layer.

[0004] The utility model is implemented as follows: it includes a long strip insulator, a flat strip-shaped object with a ratio of the long side to the short side of the cross section greater than 2 arranged on the long strip insulator, and a plurality of wires arranged on the long strip insulator. The utility model is special in that the wires are flat and embedded in a separated manner side by side on one of the wide sides of the long strip insulator, and the outer side surfaces of the wires are exposed outside the wide side surface of the long strip insulator.

[0005] During use, the power cord of the present invention is bent along its long sides, taking advantage of the bendability and rigidity of the flat strip, to create an aesthetically pleasing shape. Then, the power connector with the electric light source is connected to the designated position of the power cord according to the design requirements, so that the multiple conductive tips of the connector are closely attached to the outer surface of the matching wire, thereby completing the power connection.

[0006] By combining an insulating wrapping with a flat strip, and utilizing the bendability and rigidity of the flat strip, various curved shapes can be made, and the set shape can be conveniently fixed by a fixing structure fixed to a ceiling, a wall or a bracket. The wire is exposed on one of the wide sides of the long strip of insulation, so there is no need to pierce the insulating wrapping, making it easy to connect the power. Moreover, a conductive head with a wide contact surface can be used to contact the wire, which has sufficient contact area to ensure smooth current flow and prevents sharp objects from causing damage to the wire.

[0007] Preferably, the flat strip is made of a steel strip, a hard plastic strip, a strip of glass fiber board, or a strip of carbon fiber board.

[0008] In this way, it can be bent, and because it has a certain rigidity, it is very rigid in the long side direction and has good bending performance in the short side direction. After bending, it is easy to fix the bent shape. At the same time, it will not fall due to gravity in the long side direction and destroy the entire shape.

[0009] Preferably, a T-shaped slot is provided on one of the wide sides of the elongated insulator, and the conductor is embedded in the T-shaped slot; or a dovetail slot is provided on one of the wide sides of the elongated insulator, and the conductor with a dovetail cross-section is embedded in the dovetail slot. The use of the T-shaped slot or dovetail slot prevents the conductor from escaping from the T-shaped slot or dovetail slot.

[0010] An electrical connection head is provided, which includes an electrical connection head body provided with a flat recess that matches the flat strip-shaped conductive cable with exposed wires, an extrusion located above the recess, the depth of the recess matches the thickness of the conductive cable, a stepped recess is provided on the electrical connection head body that matches the recess, the shape of the extrusion matches the shape of the recess, the extrusion is provided at the recess and is fixed at the stepped recess by a fixed connection structure, a plurality of conductive heads that match the plurality of wires exposed on the long strip insulator and protrude from the bottom surface of the recess are provided at the bottom of the recess, the extrusion pushes the long strip insulator toward the conductive head, so that the electrical connection surface of the conductive head is in close contact with the exposed wires on the matching long strip insulator.

[0011] When in use, the electrical connector body is hung on the long strip of insulation through the notch, and then the extruded piece is fixed to the notch from the side through the fixed connection structure, and the electrical contact surface of the conductive head is close to the exposed wire on the matching long strip of insulation, thereby completing the electrical connection, so that the power can be transmitted to the conductive head through the wire, and then transmitted through the conductive head to the electrical facilities connected to the conductive head and the electrical connector body.

[0012] Since the extrusion part is located on the side and can be hung on the long strip of insulation through the notch, the operating line of sight is not easily blocked, the long strip of insulation can be accurately placed on the conductive head, the operation is convenient, accurate and reliable, and the conductive head is close to the exposed wire on the long strip of insulation, which not only ensures a firm connection and reliable power transmission, but also does not damage the exposed wire.

[0013] The stepped notch is adopted to facilitate the center of gravity of the terminal body to be hung on the long strip of insulation through the notch.

[0014] Preferably, one side of the extrusion piece is hinged to the connector body on one side of the recess through a hinge structure, and the other side of the extrusion piece is connected to the connector body on the other side of the recess through a fixed connection structure.

[0015] When in use, the extrusion piece is swung along the hinge structure so that the extrusion piece leaves the recess and the recess is in an open state. The recess is buckled on the long strip insulator so that the wires on the long strip insulator are facing the conductive head in the corresponding recess. The extrusion piece is swung along the hinge structure so that the extrusion piece presses onto the long strip insulator, driving the long strip insulator to press toward the conductive head, so that the conductive head is close to the exposed wire on the long strip insulator that transmits power, thereby completing the power connection effect. Then, through the fixed connection structure, the other side of the extrusion piece is fixedly connected to the power connection head body on the other side of the recess to ensure that the extrusion piece will not detach from the recess, and then the conductive head is stably connected to the exposed wire of the long strip insulator.

[0016] The extrusion piece is connected to the electrical head body in a hinged manner, and the swing direction of the extrusion piece is toward the notch, which makes it convenient to press the long strip of insulation toward the conductive head. At the same time, the extrusion piece is not easy to be lost, making the fixed connection of the extrusion piece convenient.

[0017] Compared with the prior art, the utility model has the advantages that the power cord can maintain a stable posture after being bent and shaped, and can be connected to the conductor without piercing the insulation layer. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] During use, the flat strip 2 is bent along its long sides to create an aesthetically pleasing shape, utilizing its bendability and rigidity.

[0029] like Figure 4 、 5As shown, a connection head 6 is provided, which includes a connection head body 9 provided with a flat recess 8 matching the long strip insulator 1, an extrusion 10 located above the recess 8, the depth of the recess 8 matching the thickness of the long strip insulator 1, and a stepped recess 11 on the connection head body 9 matching the recess 8. The shape of the extrusion 10 matches the shape of the recess 11. The extrusion 10 is arranged at the recess 11 and fixed at the recess 11 by a fixed connection structure 12. At the bottom of the recess 8, there are provided several conductive heads 13 matching the several wires 3 exposed on the long strip insulator 1 and protruding from the bottom surface of the recess 8. The extrusion 10 pushes the long strip insulator 1 toward the conductive head 13, so that the contact surface 1301 of the conductive head 13 is close to the exposed wire 3 on the conductive cable 1 that matches it.

The conductive head 13 is stuck on the through-hole 1401 of the mosaic block 14 through the step 1302 at the end of the conductive head 13. The mosaic block 14 is then embedded and fixed at the bottom of the recess 8, thereby fixing the conductive head 13. The electrical contact surface 1301 of the conductive head 13 is the outer end surface of the plate-shaped object passing through the front of the mosaic block 14.

[0031] The use of the inlay block 14 facilitates the installation and fixation of the conductive head 13 .

[0032] Preferably, one side of the extrusion piece 10 is hinged to the connector body 9 on one side of the recess 8 via a hinge structure 15 , and the other side of the extrusion piece 10 is connected to the connector body 9 on the other side of the recess 8 via a fixed connection structure 12 .

[0033] Preferably, an electric light source 16 is provided, and a connecting rod 17 is provided on the electrical connector body 9. The electric light source 16 is swingably connected to the connecting rod 17 of the electrical connector body 9 so as to obtain the power transmitted by the conductive head 13 through the power line in the connecting rod 17. At the same time, the illumination angle of the electric light source can be adjusted.

[0034] Preferably, the electrical connector body 9 includes a shell 901, a connector 902 with an inner U-shaped opening 903 fixed to the shell 901 by a snap-fit ​​structure, an outer U-shaped opening 904 is provided on the shell 901 corresponding to the inner U-shaped opening 903, the inlaid block 14 with the conductive head 13 is arranged on the bottom surface of the inner U-shaped opening 903 of the connector 902, the wire connected to the conductive head 13 is arranged between the connector 902 and the shell 901, a pair of ears 905 are provided on the connector 902, a pair of axial holes 1501 constituting the hinge structure 15 are respectively arranged on the pair of ears 905, and the axis 1502 constituting the hinge structure 15 is arranged on the swing block 1001 of the extrusion member 10.

[0035] The use of the housing 901 and the connector 902 facilitates manufacturing (can be formed by injection molding in one go), facilitates storage of the wires connected to the conductive head 7, and avoids leakage caused by exposed wires.

[0036] Preferably, the shell 901 is a cylindrical object with one end cut into a stepped portion, and the end of the connector 902 with a pair of ears 905 is inserted into the cylindrical object at the other end of the shell 901. A shell notch 906 is provided on the cylindrical object corresponding to the pair of ears 905 so that the shaft 1502 on the swing block 1001 of the extrusion part 10 can be inserted into the shaft hole 1501 of the pair of ears 905.
