DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0024] See also Figure 1 The embodiment of the present application provides a lighting device 1000, which can be used for lighting, special lighting effect display, etc. The lighting device 1000 includes a lamp 100 and an electrical connector 200. The electrical connector 200 is used to electrically connect the lamp 100 with other electrical components. For example, the electrical connector 200 can electrically connect the lamp 100 to electrical devices such as a power source, a mobile phone, and a computer host to achieve the purpose of lighting or displaying lighting effects of the lamp 100. The electrical connector 200 can also be electrically connected between two lamps 100 to establish a connection relationship for current transmission or communication transmission between the two lamps 100.

[0025] In this embodiment, the lighting device 1000 can be used as a spliced ​​lamp, and the electrical connector 200 is connected between two lamps 100. This specification does not impose any specific restrictions on the outer contour of the lamp 100. For example, the outer contour of the lamp 100 in this embodiment is a regular hexagon. A plurality of regular hexagonal lamps 100 can form a chain structure, or can be spliced ​​into a specific pattern, such as some lamps 100 spliced ​​into a petal shape in the figure. The two lamps 100 can be connected at intervals, or can be closely adjacent to form a spliced ​​connection. In addition, the electrical connection line formed between the multiple lamps 100 can be a single chain type or a mesh type. This embodiment does not impose any specific restrictions on the light color of the lamp 100. The light color of the lamp 100 can be specifically set according to the overall shape of the lighting device 1000 formed by the multiple lamps 100 and the display requirements. The light emitted by the multiple lamps 100 can be the same or different.

[0026] See also Figure 2 The lamp 100 in this embodiment includes a housing 110 and an electrical contact 120 disposed on the housing 110, and the electrical connector 200 electrically connects the two lamps 100 by electrically connecting the electrical contact 120 of the lamp 100. The housing 110 is provided with a limiting portion 111 for fixedly connecting the electrical connector 200 and the housing 110. Specifically, the electrical connector 200 includes a conductive member 210 and a terminal assembly 220, and the terminal assembly 220 is used to electrically connect the lamp 100. In this embodiment, the electrical connector 200 is used to electrically connect the two lamps 100, so the electrical connector 200 includes two terminal assemblies 220, and the two terminal assemblies 220 are respectively connected to the two ends of the conductive member 210. Both of the two terminal assemblies 220 are conductive structures, and the two terminal assemblies 220 are respectively electrically connected to the electrical contacts 120 of the two lamps 100 to make the two lamps 100 conductive. This embodiment does not limit the conductive member 210 to be a hard structure or a flexible structure. The conductive member 210 in this embodiment is a flexible wire structure 211 , so that two electrically connected lamps 100 can be constructed in a variety of positions.

[0027] See also Figure 3 and Figure 4The terminal assembly 220 in this embodiment includes a terminal body 221 and an elastic contact 222. Specifically, the terminal body 221 includes a main body portion 2211 and a clamping portion 2212 connected to each other, the main body portion 2211 is connected to the conductive member 210, and the clamping portion 2212 protrudes relative to the main body portion 2211. The clamping portion 2212 is suitable for being pressed to the limiting portion 111 to be at least partially arranged opposite to the limiting portion 111. The clamping portion 2212 can abut against the limiting portion 111, and the limiting portion 111 can limit the clamping portion 2212 and the terminal body 221 from moving in a direction away from the housing 110 to prevent the terminal assembly 220 from separating from the housing 110. The elastic contact 222 is arranged on the main body portion 2211, and the elastic contact 222 is electrically connected to the conductive member 210. When the engaging portion 2212 is limited to the limiting portion 111, the elastic contact 222 is in a squeezed state, and the elastic contact 222 elastically abuts between the main body 2211 and the electrical contact 120. On the one hand, the elastic contact 222 makes the engaging portion 2212 on the terminal main body 221 and the limiting portion 111 on the housing 110 abut tightly, which can make the matching relationship between the engaging portion 2212 and the limiting portion 111 more stable, and the terminal main body 221 is not easy to fall off from the housing 110. On the other hand, the elastic contact 222 can make the electrical connection between the electrical connector 200 and the lamp 100 more stable, and can overcome the influence of the vibration between the terminal main body 221 and the housing 110 on the electrical connection between the elastic contact 222 and the electrical contact 120.

[0028] Therefore, the lighting device 1000 in this embodiment includes a lamp 100 provided with a limiting portion 111 and an electrical connector 200 provided with a clamping portion 2212. The limiting portion 111 and the clamping portion 2212 can cooperate with each other and form a stable connection relationship, so that the electrical connector 200 and the lamp 100 can be stably connected. The elastic contact 222 further strengthens the structurally stable connection relationship between the electrical connector 200 and the lamp 100, and makes the electrical connection between the electrical connector 200 and the lamp 100 more stable, which can overcome the influence of vibration or looseness on the electrical connection relationship.

[0029] See also Figure 3 and Figure 4In this embodiment, a receiving groove 112 is provided on the housing 110, and the electrical contact 120 is arranged at the bottom of the receiving groove 112. The receiving groove 112 can accommodate part of the structure of the terminal assembly 220, so that the thickness of the housing 110 can be relatively thinned. Correspondingly, the terminal body 221 also includes a guide portion 2213, the guide portion 2213 is connected to the main body 2211 and protrudes relative to the main body 2211, and the elastic contact 222 is arranged on a side of the guide portion 2213 away from the main body 2211. When the engaging portion 2212 is limited to the limiting portion 111, the guide portion 2213 is at least partially embedded in the receiving groove 112, and the elastic contact 222 is in a squeezed state and elastically abuts between the guide portion 2213 and the electrical contact 120. The receiving groove 112 and the guide portion 2213 provided in this embodiment can form a guiding function, which helps the user to quickly find the position of the shell 110 for matching the terminal assembly 220, and quickly electrically connect the elastic contact 222 and the electrical contact 120, effectively improving the efficiency of assembling the lighting device 1000.

[0030] See also Figure 3 , Figure 4 and Figure 5 , this embodiment does not limit the specific form of the limiting portion 111. The limiting portion 111 may be a structure provided separately, or may be a structure limited by the specific structure of the housing 110 and having the function of limiting the movement of the engaging portion 2212 in a direction away from the housing 110. In this embodiment, the limiting portion 111 is formed by the specific structure of the housing 110. Specifically, the housing 110 is provided with an avoidance groove 113, and the avoidance groove 113 is connected with the receiving groove 112 via the groove wall of the receiving groove 112. The engaging portion 2212 is adapted to be pressed to enter the receiving groove 112 via the notch of the receiving groove 112, and then be embedded into the avoidance groove 113 from the groove wall of the receiving groove 112. The engaging portion 2212 is at least partially arranged opposite to the groove wall of the avoidance groove 113, and the avoidance groove 113 abuts against the engaging portion 2212 towards the groove wall of the engaging portion 2212. Therefore, the structure between the groove wall of the avoidance groove 113 facing the engaging portion 2212 and the surface of the housing 110 defines the limiting portion 111. This arrangement of the present embodiment can make full use of the specific structure of the housing 110, avoid integrating too many structures on the housing 110, and keep the surface of the housing 110 clean.

[0031] The terminal body 221 in this embodiment is provided with a plurality of engaging parts 2212, and the plurality of engaging parts 2212 are arranged at intervals on the main body 2211. Correspondingly, the housing 110 is provided with a plurality of avoidance grooves 113, and the plurality of avoidance grooves 113 are arranged one-to-one correspondingly to the plurality of engaging parts 2212. When the terminal assembly 220 and the housing 110 are in a connected state, each engaging part 2212 is embedded in a corresponding avoidance groove 113. In this embodiment, a plurality of groups of one-to-one corresponding engaging parts 2212 and avoidance grooves 113 are arranged, so that the structural connection relationship between the terminal assembly 220 and the housing 110 can be more stable, and can overcome vibrations of a certain intensity. When the lighting device 1000 is in a moving state, the structural connection relationship and the electrical connection relationship between the electrical connector 200 and the lamp 100 can be in a stable connection state, so as to ensure that the display effect of the lighting device 1000 is in a normal state.

[0032] See also Figure 3 , Figure 4 and Figure 5 In this embodiment, the engaging portion 2212 and the guiding portion 2213 are spaced apart from each other on the main body 2211, and the guiding portion 2213 is a structure with elastic deformation capability, and can be forced to move closer to or away from the guiding portion 2213. The housing 110 in this embodiment is further provided with an operating slot 114, and the operating slot 114 is connected to the accommodating slot 112, and the user can squeeze the engaging portion 2212 through the operating slot 114 to release the matching relationship between the engaging portion 2212 and the avoiding slot 113. Specifically, when the engaging portion 2212 extends into the accommodating groove 112 and the end of the engaging portion 2212 away from the main body 2211 is embedded in the avoidance groove 113, the operating groove 114 is arranged corresponding to the engaging portion 2212, and the operating groove 114 can expose the end of the engaging portion 2212 close to the main body 2211, and the end of the engaging portion 2212 close to the main body 2211 is suitable for being pressed to drive the end of the engaging portion 2212 away from the main body 2211 to be separated from the avoidance groove 113, so as to realize the release of the matching relationship between the engaging portion 2212 and the avoidance groove 113, so as to be able to remove the terminal assembly 220 from the shell 110, the operation is simple and fast, and the disassembly efficiency is improved.

[0033] See also Figure 3 and Figure 4In this embodiment, the outer peripheral side wall of the guide portion 2213 is provided with at least one positioning portion 2214, and the positioning portion 2214 protrudes relative to the guide portion 2213. The housing 110 is provided with at least one positioning groove 115, and the positioning groove 115 is connected to the accommodating groove 112. When the guide portion 2213 extends into the accommodating groove 112, the positioning portion 2214 also extends into the positioning groove 115. When the terminal assembly 220 and the housing 110 are in a connected state, the positioning portion 2214 is at least partially embedded in the positioning groove 115. The purpose of such a setting in this embodiment is to facilitate the user to determine the installation direction of the terminal assembly 220 according to the positioning portion 2214 and the positioning groove 115, so as to avoid the structural connection relationship and the electrical connection structure being falsely connected due to the wrong installation direction.

[0034] In this embodiment, when the guide portion 2213 is at least partially embedded in the receiving groove 112, the outer peripheral side wall of the guide portion 2213 abuts against the inner peripheral groove wall of the receiving groove 112 to limit the movement of the guide portion 2213 in the receiving groove 112. For example, the surfaces of the outer peripheral side wall of the guide portion 2213 and the inner peripheral groove wall of the receiving groove 112 fit each other, or at least one of the two has the ability of elastic deformation, so that the two can fit tightly. The purpose of such a setting in this embodiment is to: prevent the guide portion 2213 and the terminal body 221 from moving relative to the housing 110, to prevent the engagement portion 2212 and the avoidance groove 113 from being separated due to vibration, and to prevent the elastic contact 222 from moving and causing the electrical connection between the two lamps 100 to be interrupted.

[0035] See also Figure 6 The elastic contact 222 in this embodiment includes a contact portion 2221, a reset portion 2222 and a fixed portion 2223 which are connected in sequence. The fixed portion 2223 is connected to the guide portion 2213 of the terminal body 221, and when the terminal assembly 220 and the housing 110 are assembled, the contact portion 2221 is arranged toward the electrical contact 120. The reset portion 2222 is connected to one end of the fixed portion 2223 and is bent relative to the fixed portion 2223, and the reset portion 2222 can be elastically deformed. In this embodiment, the contact portion 2221, the reset portion 2222 and the fixed portion 2223 are integrally formed, and the elastic contact 222 is made of a conductive material with elastic deformation ability. In other embodiments, the reset portion 2222 can be an elastic structure such as a spring or an elastic sheet, and is connected between the contact portion 2221 and the fixed portion 2223. The contact portion 2221 is connected to one end of the reset portion 2222 away from the fixed portion 2223, and is bent relative to the reset portion 2222. The bending direction of the contact portion 2221 can be selected so that the contact portion 2221 and the fixed portion 2223 are arranged relatively spaced apart. When the reset portion 2222 is elastically deformed, the distance between the contact portion 2221 and the fixed portion 2223 can be changed.

[0036] This embodiment will specifically describe the state changes of each part of the elastic contact 222, so as to facilitate understanding of the working mechanism of the elastic contact 222. Specifically, the fixing portion 2223 is connected to the side of the guide portion 2213 away from the main body 2211, and the position state of the fixing portion 2223 can remain stable relative to the guide portion 2213. In the process of the guide portion 2213 extending into the receiving groove 112, the contact portion 2221 is first electrically connected to the electrical contact 120, and then the reset portion 2222 is compressed. When the guide portion 2213 and the receiving groove 112 are in a mating state, the reset portion 2222 is compressed between the contact portion 2221 and the fixing portion 2223. The reset portion 2222 stores a certain amount of elastic force, and the contact portion 2221 and the fixed portion 2223 are arranged relatively spaced apart, and the contact portion 2221 and the fixed portion 2223 have a tendency to move away from each other, so that the contact portion 2221 can be pressed against the electrical contact 120 to maintain a stable electrical connection state, so that the fixed portion 2223 can push the guide portion 2213 in the reverse direction, and then transmit the elastic force to the locking portion 2212, so that the locking portion 2212 and the limiting portion 111 are in contact.

[0037] See also Figure 3 The terminal assembly 220 in this embodiment includes at least one elastic contact 222, and at least one mounting groove 2219 is provided on the guide portion 2213 of the terminal body 221, and the mounting groove 2219 and the elastic contact 222 are arranged one by one. In order to enable the contact portion 2221 to be arranged toward the electrical contact 120 during assembly, the mounting groove 2219 is connected to the side of the guide portion 2213 away from the main body 2211, and when the elastic contact 222 is embedded in the mounting groove 2219, the contact portion 2221 of the elastic contact 222 at least partially protrudes from the surface of the terminal body 221. In this embodiment, the elastic contact 222 is partially arranged in the mounting groove 2219, which can improve the connection relationship between the elastic contact 222 and the guide portion 2213, and prevent the connection between the elastic contact 222 and the guide portion 2213 from being loosened due to collision.

Specifically, the terminal body 221 includes a main body 2211 and a clamping portion 2212 connected to each other, and the clamping portion 2212 protrudes relative to the main body 2211.

The engaging portion 2212 can abut against the limiting portion 111, and the limiting portion 111 can limit the engaging portion 2212 and the terminal body 221 from moving in a direction away from the housing 110. The elastic contact 222 is arranged on the main body 2211, and the elastic contact 222 is electrically connected to the conductive member 210. When the engaging portion 2212 is limited to the limiting portion 111, the elastic contact 222 is in a squeezed state, and the elastic contact 222 elastically abuts between the main body 2211 and the electrical contact 120. The lighting device 1000 in this embodiment includes a lamp 100 provided with a limit portion 111 and an electrical connector 200 provided with a clamping portion 2212. The limit portion 111 and the clamping portion 2212 can cooperate with each other and form a stable connection relationship, so that the electrical connector 200 and the lamp 100 can be stably connected. The elastic contact 222 further strengthens the structurally stable connection relationship between the electrical connector 200 and the lamp 100, and makes the electrical connection between the electrical connector 200 and the lamp 100 more stable, which can overcome the influence of vibration or looseness on the electrical connection relationship.
