Description

Technical Field

[0001] The invention relates to the technical field of power transmission, in particular to a power inlet plug of a power supply track and a power supply track system. Background Art

[0002] At present, the power supply on the shelf is mainly set on the back of the shelf, and the LED lamps are powered by interconnected wires. With this power supply method, it is often necessary to set holes on the shelf or to wind the wires from the back of the shelf to the front of the shelf, which makes installation inconvenient and maintenance difficult; if multiple LED lamps are set on the shelf, it will cause multiple wires to be crisscrossed in the shelf, occupying more space and affecting the overall appearance of the shelf and the display effect of goods.

[0003] In order to solve the above problems, in the prior art, power supply tracks are set up to achieve power supply at different positions. Generally, the power supply track includes a track body and a conductive strip set on the track body, and power supply is achieved through a power supply head that cooperates with the power supply track. The power of the power supply track generally comes from the power input plug at the end. In the prior art, the power input plug is generally fixed to the power supply track and cannot be disassembled. This is because the existing power supply tracks are generally added to the shelves, and are divided into surface-mounted installation and installation by inserting into the shelf column. Both of these methods can be used to disassemble and repair the power supply track. For power supply tracks that are not easy to disassemble, such as embedded power supply tracks, if the power input plug cannot be disassembled, it is inconvenient to replace and repair it separately, which increases maintenance costs.

[0034] The following further elaborates on specific embodiments of the present invention based on the accompanying drawings. It should be understood that the description of the embodiments of the present invention here does not limit the protection scope of the present invention.

[0035] As Figures 1 to 4 shown, the power supply inlet plug 1000 of the power supply track of this embodiment includes a mounting base 100, an elastic conductive member 200, and an external plug-in member 300. The mounting base 100 is used to accommodate and fix other components, playing a role of support and protection. The elastic conductive member 200 includes a fixing portion 201 and an elastic portion 202 electrically connected to the fixing portion 201. The fixing portion 201 is used to electrically connect with the external plug-in member 300. The electrical connection can be achieved by plugging, welding, etc. In this embodiment, welding is adopted. The external plug-in member 300 is used to connect to an external power source. The external plug-in member 300 can be in the form of a socket, a plug, etc., and can be with or without wires. In this embodiment, the external plug-in member 300 is a plug with wires.

[0036] The mounting base 100 is provided with a mounting cavity 101 for accommodating the electrical connection between the fixing portion 201 and the external plug-in member 300 and a locking mechanism 102 for detachably fixing the mounting base 100. The mounting cavity 101 is provided with a power-taking hole 103 for the elastic portion 202 to extend out. The elastic portion 202 is provided with a retractable electrical contact point 2021.

[0037] For the convenience of manufacturing, the mounting cavity 101 is generally formed by snapping a box body and a cover body. The cover body can be an upper cover, a lower cover, a front cover, or a rear cover. In this embodiment, the mounting cavity 101 is formed by snapping an upper box body 1011 and a lower cover 1012, and further fastened with screws 1013.

[0038] Further, the locking mechanism 102 includes a locking tongue 1021 extending outward from the installation cavity 101. In this embodiment, the locking tongue 1021 is disposed on the outer wall of the upper box body 1011. On both sides of the locking tongue 1021 are clamping edges 1022, which cooperate with the power supply rail that needs to be powered. In the middle of the locking tongue 1021 is a first locking hole 1023, and a detachable locking member 1024 is provided in the first locking hole 1023. The locking member 1024 can be a threaded fastener such as a bolt or a screw, or a structure such as a buckle or a locking pin. In this embodiment, the locking member 1024 is a screw. During the locking process of the locking member 1024, a reaction force is applied to the clamping edges 1022 to fix the mounting seat 100.

[0039] There are many forms of the elastic part in the elastic conductive member 200, such as a spring piece, a spring pin, etc. Among them, the spring pin form generally requires a spring to cooperate. To simplify the structure, further, the elastic conductive member 200 is a strip-shaped spring piece. The strip-shaped spring piece includes a rear section of the spring piece as the fixed part 201 and a front section of the spring piece as the elastic part 202. One end of the front section of the spring piece is connected to the fixed part 201, and the other end extends out of the power-taking hole 103 and bends outward to form an electrical contact end 2021. In this embodiment, the electrical contact end 2021 is arc-shaped.

[0040] Further, the installation cavity 101 is provided with an insertion block 104 extending outward for arranging the elastic part 202. The insertion block 104 includes an insertion block main body 1045 and a lower baffle 1046. The insertion block main body 1045 extends from the upper box body 1011, and the lower baffle 1046 extends from the lower cover 1012. The insertion block 104 is provided with a fixing groove 1041 for fixing the end of the front section of the spring piece. The insertion block 104 can guide and install the elastic part 202, and the end fixing can prevent the elastic part 202 from being deformed easily.

[0041] To prevent the spring piece from being permanently deformed and collapsing, and to solve the problems of poor contact and contact failure, further, the insertion block 104 is provided with a stop block 1043 located inside the electrical contact end 2021. The stop block 1043 can support the electrical contact end 2021 after the elastic part 202 loses its elasticity, preventing failure.

[0042] Further, the part of the front section of the spring piece between the electrical contact end 2021 and the rear section of the spring piece bends inward. This can improve the elasticity of the elastic part 202 and save lateral space at the same time. Here, the insertion direction of the plug is defined as the longitudinal direction, and the lateral direction is perpendicular to the longitudinal direction. The insertion block 104 is also provided with a guiding groove 1044 for guiding the elastic part 202.

[0043] Corresponding to the positive and negative lead wires, further, two elastic conductive members 200 are provided. The positional relationship between the two elastic conductive members 200 is arranged according to the arrangement of the strip-shaped conductive members in the power supply track, and they can be arranged parallel to each other, or arranged oppositely or relatively.

[0044] For a structurally compact U-shaped power supply track, when the strip-shaped conductive members are arranged on both sides, the electrical contact points 2021 of the two elastic parts 202 are arranged back to back. In this embodiment, the stop block 1043 is arranged as a cross-shaped fence between the inner sides of the two electrical contact points 2021. Further, the two elastic conductive members 200 of this embodiment are symmetrically arranged on the plug block 104.

[0045] Further, the locking tongue 1021 is located above the plug block 104, and the plug block 104 is provided with a second locking hole 1042 that is coaxially arranged with the first locking hole 1023 and cooperates with the locking member 1024. The locking member 1024 passes through the first locking hole 1023 and the second locking hole 1042 at the same time. In this embodiment, the first locking hole 1023 is a through hole, and the second locking hole 1042 and the locking member 1024 are in threaded cooperation to improve the locking effect.

[0046] The power supply plug 1000 of this embodiment can be applied to a power supply track system composed of multiple power supply tracks, specifically as Figures 5 to 9 As shown, the power supply track system of this embodiment includes a power supply track 2000 and a power supply plug 1000 arranged at the end of the power supply track 2000. The power supply track 2000 includes two relatively arranged strip-shaped baffles 2001, a bottom plate 2002, and two strip-shaped conductive members 2003. The bottom plate 2002 is located on the same side of the two strip-shaped baffles 2001 and connects the two strip-shaped baffles 2001. The two strip-shaped conductive members 2003 are respectively arranged inside the two strip-shaped baffles 2001. Correspondingly, the power supply plug 1000 includes a mounting seat 100, two elastic conductive members 200, and an external plug-in member 300.

The mounting seat 100 is provided with a mounting cavity 101 for accommodating the fixing portion 201 and electrically connecting the external plug-in member 300, and a locking mechanism 102 for detachably fixing the mounting seat 100. The mounting cavity 101 is provided with a power-taking hole 103 for the elastic portion 202 to extend out. The elastic portion 202 is provided with a retractable electrical contact point 2021, and the electrical contact points 2021 of the two elastic portions 202 are arranged back to back and respectively abut against the two strip-shaped conductive members 2003.

[0047] The power supply rail 2000 of this embodiment can be used to fix the shelf at the same time. A plurality of connection holes 2004 distributed along the length direction are provided on the bottom plate 2002. The connection holes 2004 can be fixed to the hook parts on the shelf. The strip-shaped baffle 2001 is made of metal. The power supply rail 1000 further includes a strip-shaped insulating lining plate 2005 arranged on the inner side of the strip-shaped baffle 2001, and the strip-shaped conductive part 2003 is arranged on the strip-shaped insulating lining plate 2005.

[0048] A clamping groove 2006 is provided on the inner side of the strip-shaped baffle 2001. The locking mechanism 102 includes a lock tongue 1021 extending outward from the installation cavity 101. Both sides of the lock tongue 1021 are clamping edges 1022 that cooperate with the clamping groove 2006. A first locking hole 1023 is provided in the middle of the lock tongue 1021, and a detachable locking part 1024 is provided in the first locking hole 1023. During the locking process of the locking part 1024, a reaction force is applied to the clamping edge 1022 to make the clamping edge 1022 abut against the clamping groove 2006 to generate frictional force to fix the mounting seat 100. The locking part 1024 passes through the first locking hole 1023 and abuts against or is fixedly connected to the bottom plate 2002, generating a reaction force to the clamping edge 1022, so that the clamping edge 1022 abuts against the clamping groove 2006 to generate frictional force to fix the mounting seat 100.

[0049] Further, the elastic conductive part 200 is a strip-shaped elastic piece. The strip-shaped elastic piece includes a rear section of the elastic piece as the fixing part 201 and a front section of the elastic piece as the elastic part 202. One end of the front section of the elastic piece is connected to the fixing part 201, and the other end extends out of the power-taking hole 103 and bends outward to form an electrical contact end 2021. The installation cavity 101 is provided with an insertion block 104 extending outward for arranging the elastic part 202, and the insertion block 104 is provided with a fixing groove 1041 for fixing the end of the front section of the elastic piece. The insertion block 104 can guide and install the elastic part 202, and the end fixing can prevent the elastic part 202 from being deformed easily.

[0050] Further, the clamping groove 2006 is located above the strip-shaped conductive part 2003, the lock tongue 1021 is located above the insertion block 104, and the insertion block 104 is provided with a second locking hole 1042 coaxially arranged with the first locking hole 1023 and cooperating with the locking part 1024. The locking part 1024 passes through the first locking hole 1023 and the second locking hole 1042 at the same time. Even if the locking part 1024 does not contact the bottom plate 2002 (in the case of encountering the connection hole 2004), the clamping edge 1022 can be made to abut against the clamping groove 2006 to generate frictional force to fix the mounting seat 100. In this embodiment, the first locking hole 1023 is a through hole, and the second locking hole 1042 is in threaded cooperation with the locking part 1024.
