Description

TECHNICAL FIELD

[0001] The present disclosure relates to an electrical connector and an inverter connected to a solar cell assembly including the electrical connector. BACKGROUND

[0002] A solar cell assembly can include a solar panel including solar cells and a wiring box having components, circuits, etc. connected to the solar panel.

[0003] After installing a solar assembly, it can be possible to confirm the operating state of the solar cell assembly only when using a separate communication device such as a web or an application. Since it is difficult to identify the operating state of the solar cell assembly from the solar cell assembly itself, there is a problem that the solar cell assembly is not properly managed.

[0004] To solve this problem, a solar cell assembly provided with a structure, components, etc. capable of confirming the operating state is proposed. For example, a structure in which a light source capable of indicating the operating state is provided in the solar cell assembly and the operating state of the solar cell assembly is confirmed by whether the light source is driven (i.e., whether the light source blinks, intermittently blinks, etc.) is proposed.

[0005] To this end, a structure in which a lens is positioned on a side wall of a wiring box, one side of a sensing tube into which a light source is inserted and one side of a sensing tube guide are fixed to a portion of a wiring material, and the other side of the sensing tube and the other side of the sensing tube guide are connected to the lens is proposed.

[0006] In this way, in order to confirm the operating state of the solar cell assembly, a light source, a lens, a sensing member, a sensing tube, etc. are required. In addition, in order to prevent water, an O-ring needs to be provided between the lens and the housing. In this way, as the number of components of the device for confirming the operating state of the solar cell assembly increases, the cost also increases. In addition, as the manufacturing process of the device becomes more and more complicated, there is a problem that productivity is reduced. SUMMARY

[0049] Figure 1 This is a diagram illustrating an inverter for a solar cell module according to an embodiment.

[0050] Reference Figure 1 An inverter for a solar cell module (hereinafter referred to as an "inverter") may include a substrate 100, a housing 200, a support 300, a first connector 400, a second connector 500, and a light source cover 600. For example, the inverter may be connected to a solar cell module.

[0051] An inverter can convert the current, voltage, or power generated by solar cell modules. In this respect, conversion can be a change in the value and / or type of current, voltage, or power. For example, an inverter can change the value of current, voltage, or power to another value. Furthermore, an inverter can convert current, voltage, or power from direct current (DC) to alternating current (AC) or vice versa. The current, voltage, or power converted by the inverter can be transmitted externally via cables.

[0052] A light source that coordinates with the operation of the solar cell module can be arranged on the substrate 100. For example, the light emitted from the light source can also be a signal indicating the operating state of the solar cell module. In other words, the operating state of the solar cell module can be output using various methods of light expression.

[0053] As an example, normal operation of the solar panel can be represented by turning a light on / off. For instance, when the solar panel is operating normally, the light source 110 can remain off, and when there is a problem with the solar panel, the light source 110 can be turned on. Furthermore, when the solar panel is operating normally, the light source 110 can remain on, and when there is a problem with the solar panel, the light source 110 can be turned off.

[0054] As another example, various behavioral problems of solar cell modules can be manifested based on the duration, color, and intensity of light exposure. For instance, depending on which element within the solar cell module is malfunctioning, light may be exposed at different time intervals, with different colors, and / or different intensities.

[0055] Any device that can be illuminated by light can be considered a light source without limitation. For example, a light source can be implemented as a liquid crystal display (LCD), a light-emitting diode (LED), an organic light-emitting diode (OLED), a quantum dot light-emitting diode (QLED), a μLED, etc.

[0056] The substrate 100 can be housed inside the housing 200.

[0057] The bracket 300 can be connected to the housing 200 to support the first connector 400, the second connector 500, and the light source cover 600.

[0058] The first connector 400 and the second connector 500 can be connected to the bracket 300, and can be concave or convex connectors.

[0059] The light source cover 600 can cover the light source arranged on the bracket 300 and can fix the light source 110.

[0061] Figure 2 This is a perspective view of the electrical connector according to an embodiment. Figure 3 This is a diagram illustrating the bracket, the first connector, and the second connector according to an embodiment. Figure 4 This is a diagram showing the grooves and holes of the bracket according to an embodiment.

[0062] Reference Figure 2 The electrical connector 700 may include a bracket 300, a first connector 400, a second connector 500, and a light source cover 600.

[0063] The first connector 400 and the second connector 500 are arranged such that the connectors of the inverter and the power supply are electrically and physically connected to each other or electrically and physically disconnected from each other.

[0064] The light source 110 may include an emitting portion 111 and a supporting portion 112. For example, the emitting portion 111 may be directly disposed on the support 300 and exposed to the outside. The supporting portion 112 may be arranged such that the emitting portion 111 is connected to the substrate 100. Figure 2 In the middle, the support portion 112 is shown as having The shape is not limited to this. The support portion 112 can be implemented in various shapes so that the emitting portion 111 is connected to the substrate 100.

[0065] As an example, the bracket 300, the first connector 400, and the second connector 500 can be integrally molded and implemented as a single component. The first connector 400, the second connector 500, and the bracket 300 can be integrally molded by injection molding with the first connector 400 and the second connector 500 aligned side-by-side. Subsequently, the light source 110 and the light source cover 600 can be assembled to the bracket 300. At least one of the first connector 400 and the second connector 500 can be included to protrude from the bracket 300.

[0066] By integrally molding the first connector 400, the second connector 500, and the bracket 300, the structure of the electrical connector 700 can be simplified. Therefore, the productivity of the electrical connector 700 can be improved, and its waterproof performance can also be enhanced.

[0067] As another example, at least one of the bracket 300, the first connector 400, and the second connector 500 can be implemented as a separate component.

[0068] The support 300 can be made of a material that does not deform after molding. For example, the support 300 can be made of a plastic resin, but is not limited to this.

[0069] Reference Figure 3 and Figure 4 The bracket 300 may include a hole H and a groove G.

[0070] The aperture H extends through both the front and rear of the bracket 300. Because the emitting portion 111 of the light source 110 is located within the aperture H, the emitting portion 111 can be directly exposed to the outside through the aperture H. Therefore, the user can easily identify the light emitted from the emitting portion 111. Figure 3 The image shows one aperture H, but is not limited to this. In other words, there are no restrictions on the number and arrangement of apertures H, as long as the user can easily identify the light emitted from the emitting part 111.

[0071] The groove G is used to connect the light source cover 600 to the bracket 300. For example, there can be multiple grooves G. In this case, multiple grooves G can be arranged along the periphery of the hole H, or they can be concentrated on one side of the hole H. Figure 3 The diagram shows three recesses G, but is not limited to this. There are no restrictions on the number and arrangement of the recesses G when the light source cover 600 can be stably connected to the bracket 300.

[0072] exist Figure 4 In the diagram, the inner diameter D21 of the groove G is shown as being smaller than the inner diameter D11 of the hole H, but it is not limited to this. In other words, the inner diameter D21 can be larger than the inner diameter D11, or the inner diameters D21 and D11 can be the same.

[0074] Reference Figure 5 The first connector 400 may include a first stepped surface ST1, a second stepped surface ST2, and a third stepped surface ST3. Furthermore, the first connector 400 may include a first tooth TW1, a first outer peripheral surface O1, and a third outer peripheral surface O3.

[0075] For example, the first step surface ST1, the second step surface ST2, and the third step surface ST3 can also be annular. In addition, the second step surface ST2 can be spaced apart from the first step surface ST1, and the third step surface ST3 can be spaced apart from the second step surface ST2.

[0076] For example, the first tooth TW1 can connect the first stepped surface ST1 and the second stepped surface ST2. Furthermore, the first outer peripheral surface O1 is cylindrical and can connect the second stepped surface ST2 and the third stepped surface ST3. Additionally, the third outer peripheral surface O3 is cylindrical and can connect to the third stepped surface ST3.

[0077] The bracket 300 may include a first contact surface CS1, a second contact surface CS2, a third contact surface CS3, a seventh contact surface CS7, and a ninth contact surface CS9.

[0078] For example, the first contact surface CS1 can contact the first step surface ST1, and the first contact surface CS1 can be annular. Additionally, the second contact surface CS2 can contact the second step surface ST2, and the second contact surface CS2 can be annular. Furthermore, the third contact surface CS3 can contact the third step surface ST3, and the third contact surface CS3 can be annular. Additionally, the seventh contact surface CS7 can contact the first outer peripheral surface O1, and the ninth contact surface CS9 can contact the third outer peripheral surface O3. The seventh contact surface CS7 and the ninth contact surface CS9 can also be cylindrical.

[0079] Additionally, the bracket 300 may include a third tooth TW3, which can connect the first contact surface CS1 and the second contact surface CS2.

[0080] For example, the first tooth TW1 and the third tooth TW3 can mesh with each other in a direction that increases the contact area between the bracket 300 and the first connector 400. Therefore, the connection force between the bracket 300 and the first connector 400 can be increased. Figure 5 In the diagram, the first tooth TW1 and the third tooth TW3 are shown as having a sawtooth shape, but are not limited thereto. The first tooth TW1 and the third tooth TW3 can be manufactured in various shapes (such as wavy shapes, uneven shapes, etc.) to increase the surface area of ​​contact between them.

[0081] exist Figure 5 In the figure, the outer diameter D3 of the third outer peripheral surface O3 is shown to be smaller than the outer diameter D1 of the first outer peripheral surface O1, and the radial thickness t3 of the third step surface ST3 is shown to be smaller than the radial thickness t1 of the first step surface ST1, but is not limited thereto.

[0083] Reference Figure 6 The second connector 500 may include a fourth stepped surface ST4, a fifth stepped surface ST5, and a sixth stepped surface ST6. Furthermore, the second connector 500 may include a second tooth TW2, a second outer peripheral surface O2, and a fourth outer peripheral surface O4.

[0084] For example, the fourth step surface ST4, the fifth step surface ST5, and the sixth step surface ST6 can each be annular. Furthermore, the fifth step surface ST5 can be spaced apart from the fourth step surface ST4, and the sixth step surface ST6 can be spaced apart from the fifth step surface ST5.

[0085] For example, the second tooth TW2 can connect the fourth step surface ST4 and the fifth step surface ST5. Furthermore, the second outer peripheral surface O2 is cylindrical and can connect the fifth step surface ST5 and the sixth step surface ST6. Additionally, the fourth outer peripheral surface O4 is cylindrical and can connect to the sixth step surface ST6.

[0086] The bracket 300 may include a fourth contact surface CS4, a fifth contact surface CS5, a sixth contact surface CS6, an eighth contact surface CS8, and a tenth contact surface CS10.

[0087] For example, the fourth contact surface CS4 can contact the fourth step surface ST4, and the fourth contact surface CS4 can be annular. Additionally, the fifth contact surface CS5 can contact the fifth step surface ST5, and the fifth contact surface CS5 can be annular. Furthermore, the sixth contact surface CS6 can contact the sixth step surface ST6, and the sixth contact surface CS6 can be annular. Additionally, the eighth contact surface CS8 can contact the second outer peripheral surface O2. Furthermore, the tenth contact surface CS10 can contact the fourth outer peripheral surface O4, and the eighth contact surface CS8 and the tenth contact surface CS10 can each be cylindrical.

[0088] Additionally, the bracket 300 may include a fourth tooth TW4, which can connect the fourth contact surface CS4 and the fifth contact surface CS5.

[0089] For example, the second tooth TW2 and the fourth tooth TW4 can mesh with each other in a direction that increases the contact area between the bracket 300 and the second connector 500. Therefore, the connection force between the bracket 300 and the second connector 500 can be increased. Figure 6 In the diagram, the second tooth TW2 and the fourth tooth TW4 are shown as having a sawtooth shape, but are not limited thereto. The second tooth TW2 and the fourth tooth TW4 can be manufactured in various shapes (such as wavy shapes, uneven shapes, etc.) to increase the surface area of ​​contact between them.

[0091] Figure 7 This is an enlarged view of the bracket and light source according to the embodiment. Figure 8 This is a diagram showing a light source cover according to an embodiment.

[0092] Reference Figure 7The emitting portion 111 of the light source 110 is arranged in the hole H of the bracket 300, and the supporting portion 112 is connected to the substrate 100. Furthermore, the groove G is arranged along the periphery of the hole H. (See reference...) Figure 8 The light source cover 600 may include a body 610 and at least one pin 620 protruding from the body 610.

[0093] The arrangement of pins 620 in the main body 610 can correspond to the arrangement of grooves G in the bracket 300. For example, due to Figure 7 The grooves G in the bracket are arranged in a triangular pattern, therefore the pins 620 can also be arranged in a triangular pattern. Thus, the pins 620 can be inserted into the grooves G to connect the light source cover 600 and the bracket 300. However, the arrangement of the grooves G and the pins 620 is not limited to... Figure 7 and Figure 8 The arrangements shown. In other words, there are no restrictions on the number and arrangement of pins 620 and grooves G when pins 620 can be inserted into grooves G.
