Description

Technical Field

[0001] The present invention relates to the technical field of lighting fixtures, and in particular to a guide rail and a lighting fixture. Background Art

[0002] Track-type lamps are increasingly used in stages, booths and other places. They are simple to install, easy to disassemble, and flexible. Track-type lamps are generally composed of track lights and track strips that match the track lights. The track lights are installed on the track strips and can slide on the track strips and adjust the angle of illumination. Generally, track strips have two-wire and three-wire specifications. The existing three-wire track strips include live wire, neutral wire and ground wire, which are usually routed on both sides. The ground wire is generally set on the same side as the live wire or neutral wire. Compared with the two-wire track strip, it is safer during use, but the production cost will also increase. In addition, the end of the track strip is generally connected to a junction box for connection to the mains. The junction box is generally connected to the live wire, neutral wire and ground wire of the track strip by bolts.

DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] See also Figure 1 and Figure 2The present invention provides a guide rail bar, which is used in conjunction with a guide rail lamp. The guide rail bar includes a guide rail assembly, a junction box assembly and an end cover 8, and the junction box assembly and the end cover 8 are respectively installed at both ends of the guide rail assembly. Specifically, the guide rail assembly includes a guide rail body 1 and two insulating strips 2 and two metal wires 3 that are located in the guide rail body 1 and are oppositely arranged. The two insulating strips 2 are symmetrically arranged and respectively abut against the two inner side surfaces of the guide rail body 1. Each of the two insulating strips 2 contains a metal wire 3, and the opposite sides of the two insulating strips 2 are provided with a through opening that exposes the metal wire 3. Among them, the insulating strip 2 can insulate and separate the metal wire 3 from the guide rail body 1. One of the two metal wires 3 is a live wire, and the other metal wire 3 is a neutral wire. The inner bottom surface of the guide rail body 1 includes a bare metal grounding surface, and the grounding surface corresponds to the spacing area between the two insulating strips 2.

[0044] The junction box assembly includes a junction box 4, an L / N terminal 5, a ground terminal 6, a junction box cover 7, a third fastener 401, a gasket 402 and a fourth fastener 403. Two L / N terminals 5 are installed in the junction box 4 and are respectively arranged corresponding to the two metal wires 3, and one ground terminal 6 is installed at the bottom of the junction box 4 and is arranged corresponding to the grounding surface of the inner bottom surface of the guide rail body 1. The junction box cover 7 is installed on the junction box 4 through the third fastener 401, and the junction box cover 7 covers the junction box 4 to protect the L / N terminal 5 and the ground terminal 6 and other components. The junction box 4 includes an insertion end for inserting into the inside of the guide rail body 1 and a terminal for connecting external wires. After the junction box assembly is assembled, the junction box assembly is installed on the guide rail body 1 by inserting the insertion end into the head end of the guide rail body 1 and using the third fastener 401 and the gasket 402. The two L / N terminals 5 are elastically plugged with the two metal wires 3 respectively, and the ground terminal 6 is sandwiched between the junction box 4 and the guide rail body 1 and directly contacts the grounding surface of the inner bottom surface of the guide rail body 1 .

[0045] Combination Figure 1-Figure 2 as well as Figure 7-Figure 9 The L / N terminal 5 of the present invention comprises a first conductive portion 51 elastically plugged with the metal wire 3, a second conductive portion 52 for receiving an external L / N wire, and a first fastener 53. The first conductive portion 51 and the second conductive portion 52 are formed in one piece, and the first fastener 53 is passed through the second conductive portion 52 to press the external L / N wire. In this embodiment, since the first conductive portion 51 and the second conductive portion 52 are formed in one piece, the external L / N wire pressing terminal and the L / N conductive contact spring terminal, which were originally designed separately in the traditional structure, are combined into one part, reducing the use of one fastener and the production of one pressing hole, making the structure of the L / N terminal 5 simple and reducing the cost.

[0046] Combination Figure 1-Figure 2 as well as Fig.11The ground wire terminal 6 of the present invention includes a third conductive part 61, a fourth conductive part 62 and a second fastener 63. The third conductive part 61 and the fourth conductive part 62 are formed in one piece. The second fastener 63 is inserted into the third conductive part 61 to press the external ground wire. After the guide rail is assembled, since the fourth conductive part 62 is clamped between the junction box 4 and the guide rail body 1, the fourth conductive part 62 can directly contact the grounding surface to achieve grounding without the need to use a fastener to press the wire. Since the third conductive part 61 and the fourth conductive part 62 are also formed in one piece, the external ground wire pressing terminal and the ground wire conductive contact spring terminal, which were originally designed separately in the traditional structure, are combined into one part, thereby simplifying the structure of the ground wire terminal 6 and reducing the cost.

[0047] In addition, during the wiring process between the junction box assembly and the guide rail assembly, the L / N terminal 5 and the metal wire 3 are elastically plugged, and the ground terminal 6 is directly connected to the grounding surface of the guide rail body 1, thereby solving the problem of complex wiring of existing guide rails.

[0048] See also Figure 3 The top surface of the guide rail body 1 is provided with an opening 13, and the opening 13 is used for installing the guide rail lamp and the guide rail bar. The top surface, side surface and bottom surface of the guide rail body 1 enclose an insulating strip cavity 15 for accommodating the insulating strip 2. The guide rail body 1 includes an aluminum shell and an insulating coating (such as insulating paint) coated on the surface of the aluminum shell. The inner bottom surface of the guide rail body 1 includes a grounding surface 11 that exposes the aluminum shell, and the grounding surface 11 is arranged corresponding to the opening 13. In other words, when the insulating coating is made on the surface of the aluminum shell, the insulating coating can be made avoiding the area where the grounding surface 11 is located; or the aluminum shell in the area where the grounding surface 11 is located is surface treated so that the insulating coating will not be deposited or attached in this area. An anti-reverse rib 14 is provided on the top surface of the guide rail body 1. The anti-reverse rib 14 is located on one side of the opening 13 and protrudes from the top surface of the guide rail body 1. When installing a lamp on the guide rail bar, due to the setting of the anti-reverse rib 14, the lamp can only be installed on the guide rail bar from a single direction, which can avoid the lamp being installed in reverse. The grounding surface 11 , the opening 13 and the anti-reverse rib 14 all penetrate the entire guide rail body 1 along the extension direction of the guide rail body 1 .

[0049] See also Figure 3 and Figure 4 Both ends of the bottom surface of the guide rail body 1 are provided with a third mounting hole 12 and a U-shaped mounting hole 16 penetrating the bottom surface. The third mounting hole 12 and the U-shaped mounting hole 16 are both located in the area where the grounding surface 11 is located, and the two U-shaped mounting holes 16 are located between the two third mounting holes 12. The two third mounting holes 12 are respectively used for the installation of the guide rail assembly and the junction box assembly and the installation of the guide rail assembly and the end cover 8. The two U-shaped mounting holes 16 are used for the installation of the guide rail bar and the installation surface (such as a wall).

[0050] See also Figure 5Each insulating strip 2 is provided with a first receiving cavity 21 for receiving the metal wire 3, a through-port 22 communicating with the first receiving cavity 21, and two symmetrically arranged L-shaped clamping ribs 23. The two insulating strips 2 are symmetrically inserted into the insulating strip cavity 15 of the guide rail body 1, and the L-shaped clamping ribs 23 of the two insulating strips 2 are both against the inner side surface of the guide rail body 1. The two metal wires 3 are respectively arranged in the two first receiving cavities 21, and the opposite sides of the two insulating strips 2 are provided with a through-port 22 communicating with the first receiving cavity 21. The first receiving cavity 21 and the through-port 22 both penetrate the entire insulating strip 2 along the extension direction of the insulating strip 2.

[0051] Furthermore, the cross-sectional shape of the through opening 22 is V-shaped, and the opening width of the through opening 22 on the side away from the first receiving cavity 21 is greater than the opening width on the side close to the first receiving cavity 21. When used in conjunction with a track light, the V-shaped through opening 22 can facilitate the L / N spring clip on the track light to be smoothly screwed in, ensuring that the track light is electrically connected to the metal wire 3 in the first receiving cavity 21.

[0052] See also Figure 6 In one embodiment of the present invention, the junction box assembly includes a junction box 4, two L / N terminals 5, a ground terminal 6, a junction box cover 7, a third fastener 401, a gasket 402 and a fourth fastener 403.

[0053] For details, please refer to Figure 7 and Figure 8 Each L / N terminal 5 includes a first conductive portion 51, a second conductive portion 52, a connecting portion 55 and a first fastener 53. The first conductive portion 51, the second conductive portion 52 and the connecting portion 55 are integrally formed, the connecting portion 55 is located between the first conductive portion 51 and the second conductive portion 52 and is used to electrically connect the first conductive portion 51 and the second conductive portion 52, the first conductive portion 51 is provided with a metal wire cavity 510 for elastically plugging with the metal wire 3, the second conductive portion 52 is provided with an L / N wire cavity 520 for accommodating an external L / N wire, the second conductive portion 52 is also provided with a first wire pressing hole 521 connected to the L / N wire cavity 520, and the first fastener 53 is passed through the first wire pressing hole 521 to press the external L / N wire.

[0054] The metal wire 3 can be elastically inserted into the metal wire cavity 510 to be electrically connected to the first conductive part 51, and the external L / N wire can be inserted into the L / N wire cavity 520 to be electrically connected to the second conductive part 52. When the metal wire 3 is inserted into the metal wire cavity 510, the first conductive part 51 is elastically inserted into the metal wire 3, thereby fixing the metal wire 3 on the first conductive part 51.

[0055] Specifically, the first conductive part 51 is wound and a gap 54 is formed at the winding joint of the first conductive part 51, so that the first conductive part 51 is wound into a non-closed cylindrical shape. The gap 54 extends from one end of the first conductive part 51 away from the second conductive part 52 to one end close to the second conductive part 52.

[0056] Furthermore, the slit 54 extends from the end face of the first conductive part 51 away from the second conductive part 52 to the end face of the first conductive part 51 close to the second conductive part 52. The slit 54 extends along the axial direction of the first conductive part 51, or the slit 54 extends spirally around the central axis of the first conductive part 51. The setting of the slit 54 can adjust the inner diameter of the first conductive part 51. When the width of the slit 54 increases, the inner diameter of the first conductive part 51 also increases; when the width of the slit 54 decreases, the inner diameter of the first conductive part 51 also decreases. In this way, the first conductive part 51 can be made elastic in its radial direction. When the metal wire 3 is inserted into the metal wire cavity 510, the first conductive part 51 can use its elasticity to tighten the metal wire 3, so that the metal wire 3 can be fixed without using additional fasteners such as bolts.

[0057] Furthermore, the metal wire cavity 510 includes a circular wire hole 5101 and a square wire groove that are connected to each other. The circular wire hole 5101 is formed by winding and enclosing the first conductive portion 51, and the square wire groove is formed by the gap 54. That is to say, the gap 54 in this embodiment is the square wire groove. Among them, the circular wire hole 5101 is used to plug with the circular metal wire 3, and the square wire groove is used to plug with the square metal wire 3, so that the L / N terminal block of this embodiment is suitable for connecting circular and square wires. However, the traditional L / N terminal block is generally only suitable for connecting wires of one shape.

[0058] Furthermore, a chamfered structure is provided at one end of the square wire groove away from the second conductive portion 52 , so as to facilitate the insertion of round and square wires.

[0059] The second conductive part 52 of the L / N terminal 5 includes a first folding surface 5201, a second folding surface 5202, a third folding surface 5203, a fourth folding surface 5204 and a fifth folding surface 5205 connected in sequence, and the first folding surface 5201, the second folding surface 5202, the third folding surface 5203, the fourth folding surface 5204 and the fifth folding surface 5205 enclose the L / N wire cavity 520. Among them, two latching tongues 5206 are provided on the side of the first folding surface 5201 away from the second folding surface 5202, and two latching grooves 5207 matching the latching tongues 5206 are provided between the fourth folding surface 5204 and the fifth folding surface 5205. After the second conductive part 52 is bent, the first folding surface 5201 and the fifth folding surface 5205 are overlapped, and the latching tongue 5206 on the first folding surface 5201 is locked in the latching groove 5207, so as to fix the bent second conductive part 52 and maintain its structure stable.

[0060] Among them, the first folding surface 5201, the second folding surface 5202, the fourth folding surface 5204 and the fifth folding surface 5205 are all planes, and the third folding surface 5203 is an arc surface, so that the second conductive part 52 has a structure with a lower circle and an upper part after bending.

[0061] The first crimping hole 521 includes a through hole 5211 located on the fifth folding surface 5205 and a threaded hole 5212 located on the first folding surface 5201 , and the through hole 5211 corresponds to the threaded hole 5212 .

[0062] In one embodiment, the metal wire cavity 510 is connected to the L / N wire cavity 520. Specifically, the circular wire hole 5101 coincides with the central axis of the L / N wire cavity 520, and the coaxial arrangement of the L / N wire cavity 520 and the circular wire hole 5101 can facilitate the overlap of the metal wire 3 and the external L / N wire.

[0063] Please refer to Figure 8 During the use of the L / N terminal 5, the first fastener 53 is installed on the second conductive part 52 through the first crimping hole 521 on the second conductive part 52. A slot 56 is also provided between the first conductive part 51 and the second conductive part 52, and the first conductive part 51 and the second conductive part 52 are separated by the slot 56. The slot 56 can be formed by tearing a portion between the first conductive part 51 and the second conductive part 52 to form a notch using a hardware forming process. By providing the slot 56 between the first conductive part 51 and the second conductive part 52, the bending and forming of the first conductive part 51 and the second conductive part 52 can be facilitated.

[0064] In one embodiment, the relative position of the first conductive portion 51 and the second conductive portion 52 can be adjusted by bending the connecting portion 55 .

[0065] In one embodiment, the first fastener 53 includes, but is not limited to, a screw.

[0066] See also Fig. 9 The structure of the L / N terminal of this embodiment is similar to that of the L / N terminal of the above embodiment, except that the square wire groove of this embodiment includes a first square wire groove 5102 formed by a part of the slit 54. Specifically, a convex portion 511 and a concave portion 512 are provided on the two end faces of the first conductive portion 51 corresponding to the slit 54, and the convex portions 511 and the concave portions 512 on the two opposite end faces are symmetrically arranged, and the concave portion 512 is located on the side of the convex portion 511 away from the second conductive portion 52, wherein the first square wire groove 5102 is formed by the gap between the concave portions 512 on the two end faces of the first conductive portion 51. The first square wire groove 5102 is used for elastic insertion with the square metal wire 3, and the convex portion 511 can limit the metal wire 3 to prevent the metal wire 3 from being inserted too deep. Especially when the metal wire cavity 510 is connected to the L / N wire cavity 520, the provision of the protrusion 511 can prevent the metal wire 3 from being inserted into the L / N wire cavity 520 and affecting the connection of the external L / N wire.

[0067] Furthermore, a chamfered structure 5100 is provided at one end of the first square wire groove 5102 away from the second conductive portion 52 , so as to facilitate the insertion of round and square wires.

[0068] Among them, the other structures of the L / N terminal of this embodiment are the same as the structures of the L / N terminal in the above embodiment, and therefore it also has the technical effects of the L / N terminal in the above embodiment. Please refer to the description in the above embodiment for details, which will not be repeated here.

[0069] See also Fig.10 In some embodiments of the present invention, the metal wire cavity 510 further includes a second square wire groove 5103 disposed opposite to the first square wire groove 5102, the second square wire groove 5103 is connected to the circular wire hole 5101, and the second square wire groove 5103 is also used for connecting the first conductive part 51 with the square wire. The length and groove width of the second square wire groove 5103 are equal to those of the first square wire groove 5102.

[0070] It can be understood that the second square wire groove 5103 is spaced a certain distance from the end face of the first conductive part 51 close to the second conductive part 52. In this way, while playing a limiting role, it can also make the end of the first conductive part 51 close to the second conductive part 52 have a tighter constraint in its radial direction, thereby improving the reliability of the connection between the metal wire 3 and the first conductive part 51.

[0071] In some embodiments of the present invention, two oppositely disposed slits 54 are formed on the first conductive portion 51, and the second square wire groove 5103 is also formed by a portion of one of the slits 54. Specifically, the structure of the second square wire groove 5103 is the same as that of the first square wire groove 5102. For details, please refer to the above description of the first square wire groove 5102, which will not be repeated here.

[0072] See also Fig.11 The ground terminal 6 includes a third conductive part 61 and a fourth conductive part 62, and the third conductive part 61 and the fourth conductive part 62 are integrally formed. The ground terminal 6 is bent into a fishhook shape at the intersection of the third conductive part 61 and the fourth conductive part 62, and a second pressing hole 611 penetrating the third conductive part 61 is provided on the third conductive part 61, and the second fastener 63 is used to be inserted into the second pressing hole 611.

Each L / N terminal cavity 41 includes a first conductive portion cavity 411 corresponding to the first conductive portion 51 of the L / N terminal 5 and a second conductive portion cavity 412 corresponding to the second conductive portion 52 of the L / N terminal 5, and the first conductive portion cavity 411 is connected to the second conductive portion cavity 412. For the stability of the installation of the L / N terminal 5, the shapes of the first conductive portion cavity 411 and the second conductive portion cavity 412 can match the shapes of the first conductive portion 51 and the second conductive portion 52, which can prevent the L / N terminal 5 from shaking left and right or rotating circumferentially after installation. It can be understood that in order to ensure the elasticity of the first conductive portion 51 in the circumferential direction, the inner diameter of the first conductive portion cavity 411 is greater than the outer diameter of the first conductive portion 51, so that a certain redundant space is left between the first conductive portion 51 and the inner wall of the first conductive portion cavity 411 for the first conductive portion 51 to adjust the inner diameter size. In addition, considering the convenience of installing the L / N terminal 5, the second conductive part cavity 412 can be set to a semi-open structure, that is, the upper part of the junction box 4 corresponding to the second conductive part cavity 412 is hollowed out, so as to facilitate the removal and placement of the L / N terminal 5.

[0074] Furthermore, each L / N terminal cavity 41 is provided with a buckle 44, and the L / N terminal 5 is fixed in the L / N terminal cavity 41 by the buckle 44. Specifically, during the process of inserting the L / N terminal 5 into the first conductive part cavity 411 and the second conductive part cavity 412, the L / N terminal 5 contacts the buckle 44, and the buckle 44 is pressed down by the pressure of the L / N terminal 5. When the L / N terminal 5 passes through the buckle 44, the pressure of the buckle 44 is released and the buckle 44 pops up to clamp the L / N terminal 5 and prevent the L / N terminal 5 from escaping from the L / N terminal cavity 41. Specifically, after the L / N terminal 5 is installed, the buckle 44 can be clamped at the end of the second conductive part 52 on the side away from the first conductive part 51.

[0076] The fourth conductive portion 62 of the ground terminal 6 is embedded in the ground terminal cavity 42, the third conductive portion 61 of the ground terminal 6 is bent into the junction box 4, and the second pressing hole 611 of the ground terminal 6 corresponds to the external ground cavity 43.

The junction box assembly also includes a third fastener 401 and a gasket 402. The gasket 402 can be a piercing gasket. The gasket 402 is put on the third fastener 401, and then the third fastener 401 passes through the third mounting hole 12 and the second mounting hole 621 in sequence and is installed in the first mounting hole 45, so that the installed junction box 4 is fixed on the guide rail body 1. Among them, in the process of locking the third fastener 401, the piercing flower gasket is squeezed to pierce the insulating coating on the outer bottom surface of the guide body 1. At the same time, the fourth conductive part 62 of the ground terminal 6 will further fit into the grounding surface 11 of the inner bottom surface of the guide body 1 to achieve close contact, thereby ensuring the continuity of the grounding.

[0078] Combination Figure 6 and Fig.12 , the junction box assembly also includes a fourth fastener 403 for fastening the junction box 4 and the junction box cover 7. A junction box cover mounting column 46 is also provided in the junction box 4, and the junction box cover mounting column 46 is provided with a threaded hole in the axial direction, and the top surface of the junction box cover 7 is provided with a first through hole corresponding to the threaded hole, and the fourth fastener 403 is installed in the threaded hole of the junction box cover mounting column 46 through the first through hole, so as to achieve the installation of the junction box cover 7 and the junction box 4. In addition, an easy-to-fall hole 72 is provided on the side of the junction box cover 7 away from the guide rail assembly, and the easy-to-fall hole 72 can be lifted off, and then the L wire, N wire, and ground wire of the mains are inserted into the junction box cover 7 from the easy-to-fall hole 72. Among them, the L wire and the N wire are respectively inserted into the L / N wire cavity 520 of the second conductive part 52 of the two L / N terminal blocks 5, and the first fastener 53 is locked to press the L wire and the N wire.
