Description

Technical Field

[0001] The present application relates to the field of lighting technology, and in particular to a connector and a lamp. Background Art

[0002] Outdoor lamp controllers are installed on outdoor lamps, such as street lamps, and are used to provide, for example, sensing inputs to the lamps, or to provide communication between the lamps and the network. Their purpose is to monitor and control the combination of lamps (specifically the power drivers in the lamps) to remotely manage and maintain outdoor street lamp assets.

[0003] Zhaga is an international alliance of LED (Light Emitting Diode) lighting industry cooperation organizations, aiming to develop interface standards for LED lighting components, and to define interfaces and standardize light-related components for various specific applications to enable convenient interchange of LED light sources produced by different manufacturers. Based on this, the Zhaga connector is currently a widely used standardized communication interface between LED lamps and networks.

[0004] In the prior art, the communication card in the Zhaga connector, such as the eSIM card, is integrally soldered to the circuit board. The connector itself does not support on-site opening, and the user cannot change the communication card on-site.

[0005] Communication cards that are made integrally with circuit boards require manufacturers to program their MAC addresses, which increases the manufacturing process; users cannot change to appropriate telecom operators as needed; there is also a risk of information leakage.

[0006] With the development of technology, a new hybrid architecture has emerged in the street light control system. It is not necessary to install a controller in each street light. Instead, RF mesh (a mesh network structure based on radio frequency technology) is used to realize most of the communication between controller nodes, and a segmented controller with a communication card installed is used to communicate with the network between multiple nodes in a specific area. This can greatly reduce the number of communication cards installed in the controller and save a lot of communication costs. Therefore, there is also a demand to allow users to change communication cards on site. Utility Model Content

[0042] In order to illustrate the technical solution described in this application, a detailed description is given below in conjunction with specific drawings and embodiments.

[0043] See also Figure 1 As shown, the embodiment of the present application first provides a lamp 200, which includes a power box 8, a light source unit 9, and a connector 100. The light source unit 9 is fixedly connected and electrically connected to the power box 8, and the connector 100 is fixedly arranged on the power box 8 and electrically connected to the power box 8. The power line provides power to the light source unit 9 and the connector 100 to ensure that the light source unit 9 and the connector 100 work normally. The connector 100 is used to connect to the network through a communication base station, etc., and further communicate with the control background to send the information of the lamp 200 to the control background.

[0044] See also Figure 3 and Figure 5 As shown, a circuit board 1 and a communication card 2 are arranged in the connector 100, and the communication card 2 is in physical contact with the circuit board 1 and forms a communication connection. The communication card 2 is connected to the network through the circuit board 1. The circuit board 1 is electrically connected to the power supply box 8.

[0045] The type of the lamp 200 is not limited. That is, the connector 100 can be applied to any situation where it is necessary to remotely obtain lamp operation information and remotely control lamp operation. For example, the lamp 200 can be a lamp for indoor use or a lamp for outdoor use.

[0046] In a specific embodiment, Figure 1 As shown, the lamp 200 is a lamp for outdoor use, specifically a street lamp.

[0047] The street lamp further includes a lamp post 72 and a lamp post clamp 71, one end of the lamp post clamp 71 is fixed to the outer wall of the power supply box 8, and the other end of the lamp post clamp 71 forms a socket (not shown) for inserting the upper end of the lamp post 72. The wiring for providing power to the power supply box 8 can be connected to an external power supply facility via the lamp post clamp 71 and the lamp post 72.

[0048] See also Figure 2 and Figure 3 As shown, in the embodiment of the present application, the connector 100 also includes a base plate 6 and a front shell 5, the base plate 6 and the front shell 5 are detachably connected, and a cavity (not shown) is defined between the two, and the aforementioned circuit board 1 and the card slot 4 for installing the communication card 2 are located in the cavity; the base plate 6 includes a base plate body 61 detachably connected to the front shell 5, and a cover body 65 arranged on the base plate body 61, a window 610 connected to the cavity is provided on the base plate body 61, and the aforementioned card slot 4 is arranged in the window 610; on the base plate body 61, the cover body 65 has at least two positions, a first position and a second position: in the first position, the cover body 65 can enclose the card slot 4 in the window 610, at this time the card slot 4 is closed, the communication card 2 forms a physical contact with the circuit board 1, and a communication connection is achieved, as shown in FIG. Figure 2 , Figure 5 and Figure 6 In the second position, the cover 65 allows the window 610 to be opened, thereby exposing the card slot 4 and the communication card 2. At this time, the user is allowed to open the card slot 4 and remove the communication card 2. Please refer to Figure 3 , Figure 4 and Figure 8 shown.

[0049] The connector 100 provided in the embodiment of the present application includes a detachable bottom plate 6 and a front shell 5, the bottom plate 6 includes a bottom plate body 61 and a cover body 65, a window 610 is provided on the bottom plate body 61, a card slot 4 for installing a communication card 2 is provided in the window 610, and the cover body 65 has a first position capable of closing the card slot 4 in the window 610, and a second position allowing the window 610 to be opened. Therefore, the user can be allowed to change the communication card 2 on site by switching the cover body 65 between the first position and the second position, and the manufacturer of the connector 100 does not need to solder the communication card 2 and encode the address, which reduces the manufacturer's process. In the RF mesh, the number of communication cards 2 in the connector 100 can be reduced, saving communication costs.

[0050] Please combine the specific Figure 5 As shown, the circuit board 1 is generally in the form of a sheet, and is generally in the same shape as the surface (inner surface) of the base plate body 61 facing the front shell 5, such as being generally circular. The circuit board 1 is mounted on the inner surface of the base plate body 61 to maintain a minimum spacing (0) with the communication card 2. Thus, when the card slot 4 is mounted in the window 610, direct physical contact between the communication card 2 and the circuit board 1 can be achieved.

[0051] The shape of the window 610 is not limited. Figure 3 , Figure 4 and Figure 7 As shown, the window 610 is rectangular, which matches the rectangular shape of the card slot 4. In other optional embodiments, the shape of the window 610 can also be different from the shape of the card slot 4, for example, the shape of the window 610 is oval.

[0052] See also Figures 2 to 4 As shown, one end of the cover body 65 is rotatably connected to the bottom plate body 61, and the other end of the cover body 65 is detachably connected to the bottom plate body 61. In this way, the user can remove the other end of the cover body 65 from the bottom plate body 61, and then open the window 610 by rotating the cover body 65. In addition, the cover body 65 is retained on the bottom plate body 61 by the rotational connection of one end thereof with the bottom plate body 61, and will not fall off completely. In this way, it is convenient for the user to open the cover body 65 and the card slot 4, and the disassembly operation steps of the operator will not be increased.

[0053] Specifically, see Figure 2 , Figure 3 and Figure 4 As shown, a support arm 612 is provided on the surface of the bottom plate body 61 facing away from the front shell 5; see Figure 7 and Figure 8 As shown, the support arm 612 is provided with an axial hole 6120; see Fig. 9 As shown, the cover body 65 includes a cover body 651, a mounting arm 652 disposed at one end of the cover body 651, and a mounting end 653 disposed at the other end of the cover body 651, and a rotating shaft 6521 is protruded on the mounting arm 652, and the rotating shaft 6521 is rotatably disposed in the shaft hole 6120; see Figure 2 and Figure 8 As shown, the mounting end 653 is detachably connected to the base plate body 61 .

[0054] In an alternative embodiment, see Figure 7 and Figure 8 As shown, there are two support arms 612, and the two support arms 612 are arranged in parallel and at intervals; see Fig. 9 As shown, there are two mounting arms 652, and the opposite sides of the mounting arms 652 are respectively provided with a rotating shaft 6521; see Figure 7 and Figure 8As shown, the two mounting arms 652 are located between the two supporting arms 612. In this way, firstly, the two mounting arms 652 and their two rotating shafts 6521 can ensure that the cover body 65 rotates more smoothly; secondly, the two supporting arms 612 can limit the positions of the two mounting arms 652, so that the two mounting arms 652 can only rotate but not move in the axial direction of the rotating shaft 6521, thereby preventing the mounting arms 652 from falling off the supporting arms 612.

[0055] In an optional embodiment, the rotating shafts 6521 are respectively formed on adjacent sides of the mounting arms 652 , and the two supporting arms 612 are located between the two mounting arms 652 . This is also possible.

[0056] Please refer to Figure 7 and Figure 8 As shown, the base plate body 61 is also provided with a rib 611 located between the two support arms 612 and on the side of the shaft hole 6120 close to the window 610. When the cover body 65 is in the first position, the rib 611 is located between the two mounting arms 652, and the length of the rib 611 is less than the distance between the two mounting arms 652.

[0057] The purpose of such design is that when the cover body 65 is in the first position, the rib 611 is clamped by the two mounting arms 652, and conversely, the rib 611 can maintain the shape of the mounting arms 652 to prevent the mounting arms 652 from being deformed; and in the first position, the rib 611 and the mounting arms 652 are connected in an interference fit manner, and the interaction force between the two is conducive to keeping the cover body 65 in the first position. Even if the connection between the second end of the cover body 65 and the bottom plate body 61 fails (for example, breaks) in an unexpected situation, it is difficult for the cover body 65 to rotate to the second position without the intervention of the operator. In this way, the reliability of the cover body 65 closing the window 610 is improved.

[0058] Please continue reading Figure 2 , Figure 7 and Figure 8 As shown, a connecting arm 613 is further provided on the surface of the bottom plate body 61 on the side facing away from the front shell 5, and the connecting arm 613 connects the ends of the two support arms 612 facing away from the window 610. In this way, the two support arms 612 and the connecting arm 613 together form an integral structure, and the provision of the connecting arm 613 is conducive to the two support arms 612 maintaining their respective shapes and maintaining the distance between them, so as to avoid the problem that the support arms 612 are deformed and cause the rotating shaft 6521 to fall off from the shaft hole 6120 during the opening of the cover body 65.

[0059] See also Fig. 9 As shown, a guide surface 6520 is provided on the rotating shaft 6521 , and the guide surface 6520 starts from the axial end surface 6522 of the rotating shaft 6521 and is inclined in a direction away from the cover body 651 and inclined to the central axis of the rotating shaft 6521 .

[0060] The purpose of this design is that the guide surface 6520 can facilitate the installation of the rotating shaft 6521 and the mounting arm 652 between the support arms 612, and increase the difficulty of the rotating shaft 6521 detaching from the shaft hole 6120, regardless of whether the mounting arm 652 is between the support arms 612 or the support arm 612 is between the mounting arms 652.

[0061] For details, please refer to Figure 8 and Fig. 9 As shown, taking the surface of the bottom plate body 61 facing away from the front shell 5 facing upward horizontally as an example, the mounting arms 652 of the cover body 65 are vertically facing downward. Due to the setting of the guide surface 6520, the lower ends of the two mounting arms 652 are easy to enter between the support arms 612, and the guide surface 6520 guides the two mounting arms 652 to continue to descend until the two rotating shafts 6521 completely enter the shaft hole 6120. After that, since the inclination direction of the guide surface 6520 is opposite to the cover body 651 of the cover body 65, no matter what angle the cover body 65 is rotated to, the rotating shaft 6521 is difficult to disengage from the shaft hole 6120.

[0062] As for the mounting end 653, its detachable connection with the base plate body 61 can be achieved in a variety of ways.

[0063] One implementation is that the mounting end 653 is fixed to the bottom plate body 61 by a fastener such as a screw (not shown). Specifically, the screw passes through the mounting end 653 and the bottom plate body 61 to fasten the two together; the head of the screw is located outside the cavity to facilitate the disassembly of the two.

[0064] Another way to implement this is to refer to Figures 2 to 4 ,as well as Figure 8 As shown, the end of the mounting end 653 away from the mounting arm 652 forms a buckle 6531, and the bottom plate body 61 is provided with a bayonet 6130 adapted to the buckle 6531. When the cover body 65 is rotated to the first position, the buckle 6531 enters the bayonet 6130. Conversely, the operator applies a little force to the mounting end 653 to disengage the buckle 6531, and the cover body 65 can be rotated to the second position.

[0065] Or, conversely, the end of the mounting end 653 that faces away from the mounting arm 652 forms a bayonet 6130 , and a buckle 6531 that matches the bayonet 6130 is provided on the base plate body 61 . This is also possible.

[0066] Also, see Figure 3 , Figure 4 and Figure 8As shown, a boss 6511 is formed on one side of the cover body 651 facing the cavity, and the connector 100 further includes a sealing ring 3, which is arranged on the outer peripheral surface of the boss 6511. The shape of the boss 6511 is adapted to the shape of the window 610. When the boss 6511 enters the window 610, the sealing ring 3 is located between the outer peripheral surface of the boss 6511 and the inner peripheral wall of the window 610, so that the window 610 and the cover body 651 can be sealed. In this way, when the connector 100 is used outdoors, water vapor can be prevented from entering the interior thereof, thereby avoiding affecting the normal communication work of the communication card 2 and the circuit board 1.

[0067] In one embodiment, the base plate body 61 is integrally formed, such as by integral injection molding to form the base plate body 61 and the window 610, ribs 611, support arms 612, connecting arms 613, etc. thereon; the cover body 65 can be integrally formed, such as by integral injection molding to form its cover body 651, mounting arms 652 and mounting ends 653, buckles 6531, etc.

[0068] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
