Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting equipment technology, and in particular to a housing that is easy to connect and a power supply for a fill light. Background Technology
[0002] Fill lights are devices that supplement insufficient ambient light with artificial light sources. They are widely used in photography, live streaming, beauty applications, plant growth, security monitoring, and other scenarios. Their core function is to improve lighting conditions (such as increasing brightness, adjusting color temperature, and optimizing light and shadow levels) to meet the lighting needs of different scenarios. The fill light power supply, as a core component providing stable power to the fill light itself, directly affects the assembly efficiency, usage flexibility, and subsequent maintenance convenience of the fill light due to its installation and fixing method. Currently, the mainstream fill light power supply on the market is usually installed by tightening screws. Operators need to use screwdrivers and other special tools to tighten each screw one by one. This not only consumes a lot of time and labor costs, but also easily leads to stripped screws or lost screws during the tightening process, resulting in installation failure or difficulties in subsequent disassembly and maintenance. Although some products attempt to use a snap-fit connection structure, the snap-fit design is mostly a single snap point or a linear snap-fit. During installation, it is necessary to accurately align the snap-fit position and apply a large force to complete the fixation. During operation, problems such as snap-fit misalignment and damage are prone to occur. Moreover, the stability after fixation is poor. When the fill light is moved or subjected to a slight external impact, the power supply is prone to loosening or even falling off from the main body, affecting the normal power supply of the fill light.
[0003] Therefore, it is necessary to improve the existing connection method between the power supply and the main body of the fill light to overcome the shortcomings of the existing technology. Utility Model Content
[0004] To overcome the problems existing in related technologies, one of the objectives of this utility model is to provide a housing that is easy to connect. This housing can quickly lock the power supply to the main body of the fill light through locking components. It is convenient to use, secure to install, and can ensure a stable power supply to the fill light.
[0005] A housing that facilitates connection includes a first housing and a second housing that interlock with each other;
[0006] The first housing has a cavity for accommodating a battery; the top of the first housing has a conductive contact and a locking member, the locking member is located in the middle of the first housing, and the conductive contact is located on one side of the locking member and is electrically connected to the battery in the cavity.
[0007] The locking component includes a locking bolt and a control knob. The locking bolt is rotatably mounted on the first housing, and the control knob is fixed to the locking bolt.
[0008] In a preferred embodiment of this utility model, the top of the first housing protrudes upward to form a connecting ridge, the width of the connecting ridge is smaller than the width of the bottom of the first housing, and the conductive contact and the locking member are both disposed on the connecting ridge.
[0009] The connecting ridge has a mounting position, and the control knob is located at the mounting position with its sidewall exposed outside the connecting ridge.
[0010] In a preferred embodiment of this invention, a limiting protrusion is further provided at the top of the connecting ridge, and the limiting protrusion is symmetrically arranged on both sides of the locking member.
[0011] In a preferred embodiment of this invention, a magnetic layer is provided on the top of the limiting protrusion.
[0012] In a preferred embodiment of this invention, the inner wall of the first housing is provided with a plurality of slots, and the slots are located at the bottom of the first housing.
[0013] The second housing has multiple hooks on the side where it docks with the first housing, and the hooks are adapted to the slots.
[0014] The second objective of this utility model is to provide a power supply for a fill light, including the housing described above for easy connection.
[0015] In a preferred embodiment of this invention, a circuit board is further provided inside the first housing. The circuit board is disposed on one side of the battery, and the conductive contacts and the battery are electrically connected to the circuit board.
[0016] In a preferred embodiment of this invention, a heat dissipation component is further provided inside the first housing.

[0017] In a preferred embodiment of this invention, the first housing is further provided with a charging interface, which is electrically connected to the circuit board.
[0018] The beneficial effects of this utility model are as follows:
[0019] This utility model provides an easily connectable housing, comprising a first housing and a second housing that interlock. The first housing has a cavity for accommodating a battery. The top of the first housing has conductive contacts and a locking element, with the locking element located in the middle and the conductive contacts located on one side of the locking element and electrically connected to the battery in the cavity. The locking element includes a locking bolt and a control knob. The locking bolt is rotatably mounted on the first housing, and the control knob is fixed to the locking bolt. In practical use, the battery is installed in the cavity, allowing it to be electrically connected to the conductive contacts through the circuit within the cavity. Then, the second housing is snapped onto the first housing, completing the assembly of the supplementary light power supply. When connecting to the supplementary light, the control knob is rotated, causing the locking bolt to rotate. The locking bolt, in conjunction with the supplementary light body (or a corresponding adapter structure), securely locks the power supply to the supplementary light body, while simultaneously connecting the conductive contacts to the supplementary light body's circuitry, achieving stable power supply. When the power supply needs to be disassembled, simply rotate the control knob in the opposite direction to loosen the locking bolt, thus releasing the lock and separating the power supply from the main body of the fill light. The housing utilizes a locking mechanism consisting of a control knob and a locking bolt. Operators can quickly lock or unlock the power supply and fill light by simply rotating the control knob, eliminating the need for complex tools and cumbersome steps. Compared to traditional methods of tightening screws one by one and aligning clips with snaps, the operation is significantly simplified, greatly improving the convenience of connection and disassembly, and saving time and labor costs. The structure of the locking bolt and control knob provides a stable and reliable locking force to the power supply, preventing problems such as power supply displacement and poor contact due to loose connections, ensuring continuous and stable operation of the fill light, and improving the reliability of the equipment.
[0020] This application also provides a power supply for a fill light, including the aforementioned housing. This power supply can be quickly locked onto the fill light body using a locking mechanism, making it convenient to use, securely installed, and ensuring a stable power supply to the fill light.

[0028] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.
[0029] Currently, the connection between the power supply and the main body of most fill lights on the market is usually achieved through screw fastening. Operators need to use specialized tools such as screwdrivers to tighten each screw individually, which is not only time-consuming and labor-intensive, but also prone to problems such as stripped screws or lost screws, leading to installation failure or difficulties in subsequent disassembly and maintenance. While some products attempt to use a snap-fit connection structure, the snap-fit design is mostly a single point or linear snap-fit. During installation, precise alignment of the snap-fit position and application of considerable force are required to secure it. This process is prone to problems such as snap-fit misalignment and damage, and the stability after fixing is poor. When the fill light is moved or subjected to slight external impact, the power supply can easily loosen or even detach from the main body, affecting the normal power supply of the fill light.
[0030] Based on this, this application provides a housing that facilitates connection.
[0031] Example
[0032] See Figures 1-4 This embodiment provides a housing that is easy to connect, including a first housing 1 and a second housing 2 that are interlocked with each other;
[0033] The first housing 1 is provided with a receiving cavity for accommodating the storage battery 100; the top of the first housing 1 is provided with a conductive contact 4 and a locking member 3, the locking member 3 is located in the middle of the first housing 1, and the conductive contact 4 is located on one side of the locking member 3 and is electrically connected to the storage battery 100 in the receiving cavity.
[0034] The locking component 3 includes a locking bolt 32 and a control knob 31. The locking bolt 32 is rotatably mounted on the first housing 1, and the control knob 31 is fixed on the locking bolt 32.
[0035] Specifically, both the first housing 1 and the second housing 2 can be made of plastic. The first housing 1 and the second housing 2 are interlocked to form the main body of the outer shell, providing space for the internal components. The outer shell can quickly lock the battery 100 (power supply) in the housing cavity to the main body of the supplementary light by rotating the locking bolt 32 through the operation control knob 31.
[0036] In practical use, the aforementioned easy-to-connect housing involves installing the battery 100 within the housing cavity, allowing the battery 100 to be electrically connected to the conductive contact 4 via the circuitry within the housing cavity. Then, the second housing 2 is secured to the first housing 1, completing the assembly of the supplementary light power supply. When connecting to the supplementary light, rotating the control knob 31 causes the locking bolt 32 to rotate. The locking bolt 32, in conjunction with the supplementary light body (or a corresponding adapter structure), securely locks the power supply to the supplementary light body. Simultaneously, the conductive contact 4 connects to the supplementary light body circuitry, ensuring stable power supply. To disassemble the power supply, rotating the control knob 31 in the opposite direction loosens the locking bolt 32, releasing the lock and separating the power supply from the supplementary light body. The housing features a locking mechanism 3 consisting of a control knob 31 and a locking bolt 32. Operators can quickly lock or unlock the power supply and the main body of the supplementary light simply by turning the control knob 31, eliminating the need for complex tools and cumbersome steps. Compared to traditional methods of tightening screws one by one and aligning clips with snaps, the operation is significantly simplified, greatly improving the convenience of connection and disassembly, and saving time and labor costs. The locking bolt 32, in conjunction with the control knob 31, provides a stable and reliable locking force to the power supply, preventing problems such as power supply displacement and poor contact due to loose connections, ensuring continuous and stable operation of the supplementary light, and improving the reliability of the equipment.
[0037] In a specific embodiment, the top of the first housing 1 protrudes upward to form a connecting ridge 11, the width of the connecting ridge 11 is smaller than the width of the bottom of the first housing 1, and the conductive contact 4 and the locking member 3 are both disposed on the connecting ridge 11.
[0038] A mounting position is provided at the connecting ridge 11, and the control knob 31 is located at the mounting position with its side wall exposed outside the connecting ridge 11.
[0039] When connecting the first housing 1, which houses the battery 100, to the supplementary light body, the connecting ridge 11, whose width is smaller than the bottom width of the first housing 1, is aligned with the matching connection part (such as the connecting groove) of the supplementary light body to achieve initial structural guidance and alignment. Then, the operator rotates the side wall of the control knob 31 exposed outside the connecting ridge 11. The control knob 31 drives the locking bolt 32 to rotate, and through the threaded engagement of the locking bolt 32 with the supplementary light body (or other matching locking structure), the first housing 1 (along with the battery 100) is securely locked to the supplementary light body. Simultaneously, the conductive contacts 4 on the connecting ridge 11 contact the corresponding contacts of the supplementary light body, establishing circuit continuity between the battery 100 and the supplementary light body, supplying power to the supplementary light. When disassembly is required, the control knob 31 is rotated in the opposite direction to release the locking state, thus separating the first housing 1 from the supplementary light body.
[0040] The design of the connecting ridge 11 creates a relatively narrow protruding structure on the top of the first housing 1. On the one hand, it can be adapted to the corresponding connecting slot / interface of the supplementary light body to achieve preliminary structural alignment; on the other hand, the narrow structure is conducive to the centralized arrangement of connecting related functional components, making the structure more compact and reasonable.
[0041] In a preferred embodiment, a limiting protrusion 111 is further provided on the top of the connecting ridge 11, and the limiting protrusion 111 is symmetrically arranged on both sides of the locking member 3.
[0042] Furthermore, a magnetic layer is provided on the top of the limiting protrusion 111.
[0043] The magnetic layer is made of neodymium iron boron strong magnets and is bonded to the limiting protrusions 111 with high-temperature resistant adhesive to ensure it does not fall off during long-term use. The area of the magnetic layer is the same as the top area of the limiting protrusions 111, with no exposed edges to avoid scratching the fill light body. A "magnetic adsorption area" (made of iron alloy or another set of magnetic sheets with opposite polarity to the magnetic layer) is provided at the bottom of the limiting groove of the fill light body. When the limiting protrusions 111 are inserted into the groove, the magnetic layer and the adsorption area generate a magnetic attraction force, achieving initial fixation. Specifically, during installation, the first housing 1 containing the battery 100 is aligned with the fill light body. As the connecting ridge 11 is inserted, the limiting protrusions 111 on both sides quickly insert into the limiting groove of the fill light body. At the same time, the magnetic layer on the top of the limiting protrusions 111 attracts the adsorption area at the bottom of the groove, achieving pre-positioning of the housing and the fill light body. At this time, the conductive contacts 4 are initially close to the corresponding contacts of the fill light body, maintaining a stable state without needing to be held.
[0044] Furthermore, the inner wall of the first housing 1 is provided with a plurality of slots 112, the slots 112 being located at the bottom of the first housing 1;
[0045] The second housing 2 is provided with a plurality of hooks 21 on the side where it docks with the first housing 1, and the hooks 21 are adapted to the slots 112.
[0046] Multiple slots 112 on the bottom inner wall of the first housing 1 and the matching hooks 21 on the mating side of the second housing 2 form a "snap-fit connection" structure. During assembly, it is only necessary to align the hooks 21 of the second housing 2 with the slots 112 of the first housing 1 and apply force to achieve quick snap-fit between the hooks 21 and the slots 112. The whole process does not require any tools and can improve assembly efficiency.
[0047] Example 2
[0048] This embodiment provides a power supply for a fill light, including a housing as described above for easy connection.
[0049] See Figures 1-5 Specifically, a circuit board 5 is also provided inside the first housing 1. The circuit board 5 is located on one side of the storage battery 100, and the conductive contact 4 and the storage battery 100 are electrically connected to the circuit board 5.
[0050] Furthermore, a heat sink 6 is also provided inside the first housing 1. The heat sink 6 includes a substrate 61 and a plurality of fins 62 disposed on the substrate 61. The heat sink 6 is located between the battery 100 and the circuit board 5.
[0051] Furthermore, the first housing 1 is also provided with a charging interface 7, which is electrically connected to the circuit board 5.
[0052] Specifically, the positive and negative terminals of the battery 100 are soldered to the battery 100 interface of the circuit board 5 via wires, realizing the power transfer between the battery 100 and the circuit board 5; the pins of the conductive contact 4 pass through the inner wall of the connecting ridge 11 and are electrically connected to the output interface of the circuit board 5, ensuring that the power is transmitted to the main body of the supplementary light after being regulated and filtered by the circuit board 5. The circuit board 5 can integrate the circuits of the battery 100 and the conductive contact 4, stabilize the output voltage through the voltage regulator chip, and prevent the battery 100 from short-circuiting through the overcurrent protection chip, thus solving the instability problem of traditional scattered circuits.
[0053] The heat sink 6 absorbs the heat from the charging and discharging of the battery 100 and the heat generated by the components of the circuit board 5 through the substrate 61, and then expands the heat dissipation area through the fins 62. The heat is transferred to the first housing 1 by air convection and finally dissipated to the outside, achieving dual heat dissipation of "active conduction + passive convection".
[0054] When the power supply is charging, the Type-C plug of the external charger is inserted into the charging port 7 on the side of the first housing 1, and the dust plug automatically flips open. Electrical energy is transmitted through the charging port 7 to the charging management module of the circuit board 5. The module regulates and limits the current and voltage before charging the battery 100 in the housing cavity. During charging, the heat generated by the battery 100 is conducted to the fins 62 through the substrate 61 of the heat sink 6. The fins 62 dissipate the heat to the outside of the first housing 1 to prevent the battery 100 from overheating. In use, the first housing 1 containing the battery 100 is aligned with the fill light body. When the connecting ridge 11 is inserted, the limiting protrusions 111 on both sides are embedded into the limiting grooves of the fill light body, and the magnetic layer attracts to achieve pre-fixation. Rotating the control knob 31 drives the locking bolt 32 to firmly lock the connecting ridge 11. At this time, the battery 100 outputs a stable voltage through the circuit board 5, which is transmitted to the fill light body through the conductive contact 4 to realize power supply. During the power supply process, the heat of the circuit board 5 and the battery 100 is dissipated in real time through the heat sink 6 to ensure temperature stability.
[0055] When disassembly is required, turn the control knob 31 in the opposite direction to loosen the locking bolt 32, lift the first housing 1 to release the magnetic adsorption, and the power supply and the main body of the supplementary light can be separated.
