Description

Technical Field

[0001] The present invention relates to the technical field of track lights, and particularly to a planar corner connecting piece for a track conductive circuit. Background Art

[0002] A track light generally includes a track and a lamp. The track has a track groove in which a conductive bar is provided (the conductive bar can be made of copper or iron). The conductive bar includes a live wire and a neutral wire, and a live wire and a neutral wire form a conductive circuit. To connect to an external power supply, a junction box is also provided on the track. The junction box connects the conductive circuit to the external power supply wire to conduct the conductive circuit. The lamp is fixedly or slidably mounted on the track groove, and conductive terminals are provided at the joints of the lamp. During installation, the conductive terminals on the lamp contact the conductive bar inside the track groove, thereby realizing the power-on of the lamp.

[0003] In the prior art, in order to meet the installation requirements, it is usually necessary to perform planar corner splicing on at least two separate long strip-shaped track bars to form an L-shaped track. When performing planar corner splicing on at least two separate long strip-shaped track bars, in order to reduce the use of junction boxes, it is usually necessary to splice the conductive bars in adjacent track bars as well. However, in practice, since the conductive bars in adjacent track bars are connected by direct contact, it is easy to have poor contact, resulting in the situation that the lamps on adjacent track bars cannot achieve stable electrical connection. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a planar connecting piece for a track conductive circuit, which can realize reliable connection between the conductive circuits in adjacent track bars connected in a planar corner docking manner, thereby ensuring stable power supply for the lamps on adjacent track bars.

[0005] The purpose of the present invention is achieved by adopting the following technical solutions:

[0006] A planar corner connecting piece for a track conductive circuit is used to connect the conductive circuits between adjacent track bars. The adjacent track bars are connected together in a planar corner docking manner to form an L-shaped track. It includes an L-shaped insulating housing and an L-shaped conductive connecting piece. The L-shaped insulating housing includes a first connecting portion and a second connecting portion. The first connecting portion and the second connecting portion are connected to form the L-shaped insulating housing, and the first connecting portion and the second connecting portion are located on the same horizontal plane. The L-shaped insulating housing is used to cooperate with the track groove at the corner position of the L-shaped track. The shape of the L-shaped conductive connecting piece is adapted to the shape of the L-shaped insulating housing. The L-shaped conductive connecting piece is installed in the L-shaped insulating housing, and both ends of the L-shaped conductive connecting piece are exposed at the bottom of the L-shaped insulating housing. Both ends of the L-shaped conductive connecting piece form contacts for abutting against the conductive bar.

[0007] Further, the contact is a contact that arches outwards, and the bottom surface of the contact is used to abut against the conductive bar.

[0008] Further, at least one pair of clamping blocks are provided on the L-shaped insulating housing, and the pair of clamping blocks are respectively located on both sides of the L-shaped insulating housing, and the clamping blocks are used for clamping and cooperating with the inner side wall of the track bar.

[0009] Further, at least one pair of the clamping blocks are located on both sides of the corner position of the L-shaped insulating housing, and the clamping blocks extend from the side wall of the first connecting portion to the side wall of the second connecting portion.

[0010] Further, the L-shaped insulating housing includes a detachable upper housing and a lower housing. The bottom of the upper housing is provided with an L-shaped positioning blind groove, and the L-shaped positioning blind groove extends from one end of the upper housing to the other end. The L-shaped conductive connecting piece is installed in the L-shaped positioning blind groove, and the lower housing is buckled on the lower housing.

[0011] Further, the contact is also clamped in the L-shaped positioning blind groove, and the bottom of the contact extends out along the opening of the L-shaped positioning blind groove.

[0012] Further, the top of the lower housing is provided with an L-shaped protruding portion, and the L-shaped protruding portion abuts against the L-shaped conductive connecting piece.

[0013] Further, the bottom of the upper housing is provided with a first clamping groove, and the top of the lower housing is provided with a clamping post, and the clamping post is clamped and cooperated with the first clamping groove.

[0014] Further, the upper housing includes a top plate and at least three L-shaped side plates provided on the top plate. The adjacent L-shaped side plates are arranged at intervals and enclose to form the L-shaped positioning blind groove. The heights of the two L-shaped side plates at the outermost side of the top plate are higher than the height of the L-shaped side plate at the middle position of the top plate. A second clamping groove is formed by enclosing between the two L-shaped side plates at the outermost side of the top plate. The lower housing is buckled in the second clamping groove, and an avoidance notch is formed between the end of the top plate and the end of the lower housing. The contact extends out of the L-shaped insulating housing along the avoidance notch.

[0015] Further, there are at least two L-shaped conductive connecting pieces, and the lengths of the L-shaped conductive connecting pieces are the same. Correspondingly, there are at least two L-shaped positioning blind grooves, and the adjacent L-shaped positioning blind grooves are arranged at intervals.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] During installation, the L-shaped insulating housing is inserted into the track groove at the corner position of the L-shaped track formed by butt-jointing in a planar corner manner, so that both ends of the L-shaped insulating housing are respectively connected to adjacent track bars, and the contacts at both ends of the L-shaped conductive connecting piece are respectively abutted against the conductive bars on the adjacent track bars, enabling the conductive lines on the adjacent track bars to be conducted. The limiting cooperation between the L-shaped insulating housing and the track groove plays a limiting role on the contacts, providing insulation protection for the L-shaped conductive connecting piece while ensuring that the contacts can reliably contact the conductive bars, thereby realizing a reliable connection between the conductive lines in the adjacent track bars and then ensuring the stable power supply of the lamps on the adjacent track bars.

For example, it can be fixedly connected, detachably connected, or integrally connected; it can be mechanically connected or electrically connected; it can be directly connected or indirectly connected through an intermediate medium, or the internal communication of two elements.

[0029] See Figure 1 , which is a schematic structural diagram of the installation of the planar corner connector of the track conductive circuit of a preferred embodiment of the present invention at the connection position between two adjacent track bars 3. Among them, Figure 1 The adjacent track bars 3 shown in are connected together in a planar corner docking manner, that is, the adjacent track bars 3 are all located on the same horizontal plane and are spliced to form an L-shaped track.

[0030] See Figures 2 - 5, which shows a planar corner connector for an orbital conductive circuit according to a preferred embodiment of the present invention. The planar corner connector for the orbital conductive circuit includes an L-shaped insulating housing 1 and at least two L-shaped conductive connecting pieces 2. Among them, the L-shaped insulating housing 1 is injection-molded using a plastic material, such as PVC material. The material of the L-shaped conductive connecting piece 2 is preferably a metal conductive material, such as copper material with excellent conductivity and low price. The L-shaped insulating housing 1 includes a first connecting portion and a second connecting portion. The first connecting portion and the second connecting portion are connected to form the L-shaped insulating housing 1, and the first connecting portion and the second connecting portion are located on the same horizontal plane. It can be understood that the first connecting portion and the second connecting portion can be vertically connected together or connected together in an approximately vertical inclined manner. The L-shaped insulating housing 1 is used to cooperate with the track groove at the corner position of the L-shaped track, so that the planar corner connector for the orbital conductive circuit can be embedded into the track groove at the corner position of the L-shaped track and connect adjacent track bars 3. The shape of the L-shaped conductive connecting piece 2 is adapted to the shape of the L-shaped insulating housing 1. The L-shaped conductive connecting piece 2 is installed inside the L-shaped insulating housing 1, and both ends of the L-shaped conductive connecting piece 2 are exposed at the bottom of the L-shaped insulating housing 1. Both ends of the L-shaped conductive connecting piece 2 form contacts 21 for abutting against the conductive bar 31.

[0031] During installation, by embedding the L-shaped insulating housing 1 into the track groove at the corner position of the L-shaped track formed by planar corner docking, both ends of the L-shaped insulating housing 1 are respectively connected to adjacent track bars 3, and the contacts 21 located at both ends of the L-shaped conductive connecting piece 2 are respectively abutted against the conductive bars 31 on the adjacent track bars 3, so that the conductive circuits on the adjacent track bars 3 are conducted. The limiting cooperation between the L-shaped insulating housing 1 and the track groove plays a limiting role on the contacts 21. While insulating and protecting the L-shaped conductive connecting piece 2, it ensures that the contacts 21 can reliably contact the conductive bars 31, thereby realizing the reliable connection between the conductive circuits in the adjacent track bars 3, and then ensuring the stable power supply of the lamps on the adjacent track bars 3.

[0032] As Figure 3 or Figure 5 shown, as a preferred embodiment, the contact 21 is a contact 21 arched outward. The bottom surface of the contact 21 is used to abut against the conductive bar 31. By setting the contact 21 as an arched contact 21, it is convenient for the contact 21 to penetrate outside the L-shaped insulating housing 1, and at the same time, it can improve the anti-deformation performance of the contact 21, so that when the contact 21 abuts against the conductive bar 31, it is not easy to deflect away from the conductive bar 31 or be squeezed and deformed, thereby ensuring the reliable contact between the contact 21 and the conductive bar 31 and further improving the stability.

[0033] As a preferred embodiment, the width dimension of the contact 21 is larger than the outer diameter of the conductive bar 31 to ensure that the contact 21 can reliably contact the conductive bar 31 and further improve the stability.

[0034] As a preferred embodiment, at least a pair of clamping blocks 13 are provided on the L-shaped insulating housing 1. The pair of clamping blocks 13 are respectively located on both sides of the L-shaped insulating housing 1. The clamping blocks 13 are used for tightly clamping and mating with the inner side wall of the track bar 3. As Figure 1 shown, during installation, the two sides of the L-shaped insulating housing 1 provided with the clamping blocks 13 are respectively arranged opposite to the two inner side walls of the track groove. The clamping blocks 13 are tightly clamped and mated with the grooves 32 on the inner side wall of the track bar 3, so that the L-shaped insulating housing 1 can be reliably installed in the track groove, improving the connection stability between the L-shaped insulating housing 1 and the track groove to ensure the reliable connection between the contact 21 and the conductive bar 31.

[0035] Referring to Figure 2 , in this embodiment, at least a pair of clamping blocks 13 are respectively located on both sides of the corner position of the L-shaped insulating housing 1, that is, the shape of the clamping block 13 is L-shaped. The clamping block 13 extends from the side wall of the first connecting portion to the side wall of the second connecting portion. While ensuring that both the first connecting portion and the second connecting portion are reliably clamped in the track groove, the integral L-shaped clamping block 13 is also beneficial to reducing the manufacturing difficulty of the L-shaped insulating housing 1.

[0036] Continuing to refer to Figure 3 or Figure 5 , the L-shaped insulating housing 1 includes a detachable upper housing 11 and a lower housing 12. Among them, to achieve the detachable connection between the upper housing 11 and the lower housing 12, a first card slot 1121 is opened at the bottom of the upper housing 11, and a card post 122 is provided at the top of the lower housing 12. The card post 122 is tightly clamped and mated with the first card slot 1121. Of course, the upper housing 11 and the lower housing 12 can also be fixed together by means of screw connection.

[0037] As Figure 6As shown in the figure, the upper housing 11 includes a top plate 111 and at least three L-shaped side plates 112. The L-shaped side plates 112 are installed on the top plate 111. The adjacent L-shaped side plates 112 are spaced apart and enclose an L-shaped positioning blind groove 113 with the top plate 111. The L-shaped positioning blind groove 113 extends from one end of the top plate 111 to the other end. The L-shaped conductive connecting piece 2 is installed in the L-shaped positioning blind groove 113. Among them, the heights of the two L-shaped side plates 112 located on the outermost side of the top plate 111 are higher than the height of the L-shaped side plate 112 located in the middle of the top plate 111, and a second clamping groove is formed between the two L-shaped side plates 112 located on the outermost side of the top plate 111. The lower housing 12 is buckled in the second clamping groove. When the lower housing 12 is buckled in the second clamping groove, both sides of the lower housing 12 are tightly clamped and matched with the two L-shaped side plates 112 located on the outermost side of the top plate 111, so that the upper housing 11 and the lower housing 12 are reliably connected together. By providing an L-shaped positioning blind groove 113 adapted to the L-shaped conductive connecting piece 2 on the upper housing 11, the L-shaped conductive connecting piece 2 is limited, preventing it from moving left and right, and enabling the L-shaped conductive connecting piece 2 to be firmly installed in the upper housing 11, thereby ensuring reliable contact between the contact 21 and the conductive bar 31.

[0038] Continue to refer to Figure 4 , a relief notch is formed between the end of the top plate 111 and the end of the lower housing 12, and the contact 21 extends out of the L-shaped insulating housing 1 along the relief notch.

[0039] As a preferred embodiment, the contact 21 is also clamped in the L-shaped positioning blind groove 113. Specifically, refer to Figure 4 , both sides of the contact 21 are tightly clamped and matched with the adjacent L-shaped side plates 112, and the bottom of the contact 21 extends out along the opening of the L-shaped positioning blind groove 113, so that the bottom of the contact 21 can contact the conductive bar 31 located on the track groove. By clamping the contact 21 in the L-shaped positioning blind groove 113, the contact 21 can be limited, preventing it from moving, and making the connection between it and the conductive bar 31 located on the track groove more reliable.

[0040] To further improve the connection stability between the upper housing 11 and the lower housing 12, third clamping grooves 1122 are formed on the inner sides of the two L-shaped side plates 112 located on the outermost side of the top plate 111, and clamping tenons 123 are provided on the outer side wall of the lower housing 12. When the upper housing 11 and the lower housing 12 are buckled together, the clamping tenons 123 are engaged with the third clamping grooves 1122.

[0041] As Figure 7As shown, as a preferred embodiment, an L-shaped protrusion 121 is provided at the top of the lower housing 12. The L-shaped protrusion 121 abuts against the L-shaped conductive connection piece 2, and the L-shaped protrusion 121 plays a limiting role on the L-shaped conductive connection piece 2 to prevent the L-shaped conductive connection piece 2 from moving back and forth, so that it is more firmly installed in the upper housing 11, further improving the connection stability between the contact 21 and the conductive bar 31.

[0042] As a preferred embodiment, at least two L-shaped conductive connection pieces 2 are provided. One of the L-shaped conductive connection pieces 2 is used to connect the live wire in the adjacent conductive bars 31, and the other L-shaped conductive connection piece 2 is used to connect the neutral wire in the adjacent conductive bars 31. The lengths of the two L-shaped conductive connection pieces 2 are the same to facilitate reducing the processing difficulty and improving the manufacturing efficiency. Correspondingly, at least two L-shaped positioning blind slots 113 are provided, and the adjacent L-shaped positioning blind slots 113 are arranged at intervals to ensure that the adjacent L-shaped conductive connection pieces 2 do not interfere with each other.

[0043] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantive changes and substitutions made by those skilled in the art based on the present invention belong to the scope of protection required by the present invention.
