Description

Technical Field

[0001] The invention relates to the technical field of track lights, and in particular to a track conductive line straight connecting piece. Background Art

[0002] Track lights generally include tracks and lamps. The track has a track groove in which a conductive strip is provided (the conductive strip can be made of copper or iron). The conductive strip includes a live wire and a neutral wire. The live wire and the neutral wire form a conductive circuit. In order to access an external power supply, a junction box is also provided on the track. The junction box connects the conductive circuit with the external power line to conduct the conductive circuit. The lamp is fixedly or slidably installed on the track groove, and a conductive terminal is provided at the joint of the lamp. During installation, the conductive terminal on the lamp contacts the conductive strip inside the track groove, thereby energizing the lamp.

[0003] In the prior art, in order to meet installation requirements, it is usually necessary to straightly splice at least two separate long track bars to form a continuous long track. When straightly splicing at least two separate long track bars, in order to reduce the use of junction boxes, it is usually necessary to splice the conductive strips in adjacent track bars. However, in practice, since the conductive strips in adjacent track bars are connected by direct contact, poor contact is prone to occur, resulting in the lamps on the adjacent track bars being unable to achieve stable electrical connection.

[0031] See also Figure 1 , is a schematic diagram of a structure in which a track conductive line straight connecting member is installed at a connection position between two adjacent track bars 6 in a preferred embodiment of the present invention, wherein: Figure 1 The adjacent track bars 6 shown in FIG. 1 are connected together in a straight line connection.

[0032] like Figure 2-Figure 5As shown, a track conductive line straight connector of a preferred embodiment of the present invention is shown, which is used to connect the conductive lines between adjacent track bars 6. The adjacent track bars 6 are connected together in a straight line connection manner to form a long track. The track conductive line straight connector includes an insulating shell 1 and at least two conductive connecting pieces 2, wherein the insulating shell 1 is injection molded using a plastic material, such as PVC material, and the material of the conductive connecting piece 2 is preferably a metal conductive material, such as a copper material with excellent conductivity and low price. The insulating shell 1 and the conductive connecting piece 2 are both in the shape of a long strip, so as to be suitable for connecting the conductive lines between adjacent track bars 6 connected together in a straight line connection manner. The insulating shell 1 is used to cooperate with the track groove of the long track bar 6, that is, the outer contour shape of the insulating shell 1 is adapted to the shape of the track groove, and the conductive connecting piece 2 is installed in the insulating shell 1 in a manner in which its length direction is parallel to the length direction of the insulating shell 1, and both ends of the conductive connecting piece 2 are exposed at the bottom of the insulating shell 1. When installed, the bottom of the insulating shell 1 is opposite to the conductive bar 7 in the track bar 6, and both ends of the conductive connecting piece 2 form contacts 21 for abutting against the conductive bar 7.

[0033] When installing the track conductive circuit straight-line connector of the present invention, the insulating shell 1 is embedded in the track groove of the long track formed by linear connection, so that the two ends of the insulating shell 1 are respectively connected to the adjacent track bars 6, and the contacts 21 located at the two ends of the conductive connecting piece 2 are respectively abutted against the conductive strip 7 on the adjacent track bar 6, so that the conductive circuits on the adjacent track bars 6 can be connected, and the limiting cooperation between the insulating shell 1 and the track groove is used to limit the contacts 21, while the conductive connecting piece 2 is insulated and protected, it is ensured that the contacts 21 can reliably contact the conductive strip 7, thereby realizing reliable connection between the conductive circuits in the adjacent track bars 6, and then ensuring stable power supply to the lamps on the adjacent track bars 6.

[0034] See also Figure 4 or Figure 8 As a preferred embodiment, the contact 21 is an outwardly arched contact 21, and the bottom surface of the contact 21 is used to abut against the conductive strip 7. By setting the contact 21 as an arched contact 21, it is convenient for the contact 21 to pass through the insulating housing 1, and at the same time, the deformation resistance of the contact 21 can be improved, so that when the contact 21 abuts against the conductive strip 7, it is not easy to deviate in the direction away from the conductive strip 7 or be squeezed and deformed, thereby ensuring that the contact 21 is in reliable contact with the conductive strip 7 and further improving the stability.

[0035] As a preferred embodiment, the width of the contact 21 is larger than the outer diameter of the conductive bar 7 to ensure that the contact 21 can reliably contact the conductive bar 7 and further improve stability.

[0036] like Figure 5As shown, the insulating housing 1 includes an upper housing 11 and a lower housing 12 that are detachably connected together. By providing the insulating housing 1 in a split form, the difficulty of manufacturing and assembling the insulating housing 1 can be reduced, and the installation of the conductive connecting sheet 2 can also be facilitated. Figure 7 As shown, the lower shell 12 is provided with a positioning blind groove 121, and the lower shell 12 is also provided with a first notch 122 connected to the positioning blind groove 121. The lower shell 12 is provided with a first notch 122 at positions close to both ends of the positioning groove. The conductive connecting piece 2 is installed in the positioning blind groove 121 to limit the conductive connecting piece 2 and prevent the conductive connecting piece 2 from moving left and right, so that the conductive connecting piece 2 is firmly installed in the lower shell 12, thereby ensuring that the contact 21 is in reliable contact with the conductive strip 7. The contact 21 extends out of the lower shell 12 along the first notch 122. The lower shell 12 is also provided with a limiting groove 123, and the upper shell 11 is snapped into the limiting groove 123.

[0037] like Figure 6 As shown, as a preferred embodiment, a limiting protrusion 112 is fixedly provided at the bottom of the upper shell 11. During installation, the limiting protrusion 112 abuts against the conductive connecting piece 2. The limiting protrusion 112 limits the conductive connecting piece 2 to prevent the conductive connecting piece 2 from moving back and forth, so that the conductive connecting piece 2 is more securely installed in the lower shell 12, thereby further improving the connection stability between the contact 21 and the conductive strip 7.

[0038] In order to realize the detachable connection between the upper shell 11 and the lower shell 12, the outer wall of the upper shell 11 is provided with a tenon 111, and the lower shell 12 is provided with a first slot 124 that cooperates with the tenon 111. Through the cooperation between the tenon 111 and the first slot 124, the disassembly and assembly between the upper shell 11 and the lower shell 12 is more convenient, and the disassembly and assembly efficiency is effectively improved. Of course, the detachable connection between the upper shell 11 and the lower shell 12 can also be realized by screw connection.

[0039] like Figure 5 As shown, as a preferred embodiment, the insulating housing 1 further includes a limit block 5, specifically as shown in Fig. 9 As shown, the limit block 5 includes a first limit portion 51 and a second limit portion 52 connected to each other, the lower shell 12 is also provided with a second card slot, the first limit portion 51 cooperates with the second card slot, and a third card slot 113 is provided at the bottom of the upper shell 11, the second limit portion 52 cooperates with the third card slot 113, so that the connection stability between the upper shell 11 and the lower shell 12 can be further strengthened.

[0040] In order to further strengthen the connection between the upper shell 11 and the lower shell 12 , the limit block 5 further includes a positioning portion 53 . The upper shell 11 further defines a second notch 114 , which cooperates with the positioning portion 53 .

[0041] As a preferred embodiment, at least one pair of card blocks 3 is provided on the insulating shell 1, and the pair of card blocks 3 are respectively located on both sides of the insulating shell 1. During installation, the insulating shell 1 is provided with two sides of the card blocks 3 respectively arranged opposite to the two inner side walls of the track groove, and the card blocks 3 are used to fit tightly with the inner side walls of the track bar 6 so that the insulating shell 1 can be reliably installed in the track groove, thereby improving the connection stability between the insulating shell 1 and the track groove, so as to ensure a reliable connection between the contact 21 and the conductive bar 7.

[0042] like Figure 5 As shown, to facilitate the disassembly and assembly of the track conductive line straight connector, the block 3 includes a connected guide portion 31 and a clamping portion 32 for clamping with the inner wall of the track bar 6, and the lower shell 12 is provided with a guide groove 125, which extends from one side of the lower shell 12 to the other side thereof, and both sides of the lower shell 12 are provided with a third notch 126 connected to the guide groove 125, the guide portion 31 can be slidably installed in the guide groove 125, the clamping portion 32 passes through the third notch 126 and extends out of the lower shell 12, and a spring 4 is provided between the two guide portions 31 on both sides of the lower shell 12, and the spring 4 is used to provide elastic support force to the block 3. By making the guide part 31 slidably installed in the guide groove 125, and arranging the spring 4 between the two guide parts 31, the clamping block 3 can be extended and retracted. During installation, the insulating housing 1 can be placed in the track groove by retracting the clamping part 32 into the insulating housing 1, and the clamping part 32 is loosened. The clamping part 32 is clamped with the side wall of the track groove under the action of the spring 4, so that the installation of the track conductive line straight connecting member is realized. During disassembly, the clamping part 32 is pressed to retract it into the insulating housing 1, and then the insulating housing 1 is disconnected from the track groove, so that the track conductive line straight connecting member can be disassembled, and the disassembly and assembly are relatively convenient.

[0043] In order to prevent the block 3 from being overextended and disconnected from the guide groove 125, the outer diameter of the guide portion 31 can be made larger than the diameter of the third notch 126, or Figure 3 As shown, a limiting column 33 can be provided at the top of the guide portion 31, and the first limiting portion 51 can be extended to the top of the guide portion 31 to limit the guide portion 31. At the same time, a fourth notch 511 is opened on the first limiting portion 51 to allow the limiting column 33 to pass through the fourth notch 511. When the clamping portion 32 extends outward into place, the limiting column 33 abuts against the edge of the fourth notch 511 to limit the clamping portion 32.

[0044] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
