[0030] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0031] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this utility model application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "an embodiment" or "an embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0032] The following is combined Figures 1 to 9 This invention describes a continuity detection device for a junction box according to some embodiments of the present invention.

[0033] Currently, junction boxes, as crucial wiring components in power systems, play a vital role in ensuring the continuity of circuits between their interfaces, thereby guaranteeing the stable operation of the power system. For example... Figure 1 As shown, the current junction box has multiple wiring interfaces, including a first output interface 100, a first input interface 200, and a second input interface 300 that are interconnected. Specifically, inside the junction box, the first output interface 100 and the first input interface 200 are connected by a circuit, the first output interface 100 and the second input interface 300 are connected by a circuit, and the first input interface 200 and the second input interface 300 are connected by a circuit.

[0034] Furthermore, such as Figure 2As shown in the figure, an embodiment of the present invention provides a connection / disconnection detection device for a junction box, comprising: a first connection / disconnection detector 400, a second connection / disconnection detector 500, and a third connection / disconnection detector 600.

[0035] Specifically, the first continuity detector 400 is connected to the first input interface 200 and the second input interface 300 respectively. In actual testing, the first interface of the first continuity detector 400 can be connected to the first input interface 200, and the second interface of the first continuity detector 400 can be connected to the second input interface 300.

[0036] Furthermore, when the circuit between the first input interface 200 and the second input interface 300 in the junction box is connected, the first continuity detector 400 forms a connection loop with the circuit between the first input interface 200 and the second input interface 300, so that the first continuity detector 400 issues a connection indication signal; here, the first continuity detector 400 includes a first circuit power supply (not shown in the figure) and a first indicator light (not shown in the figure), and the first circuit power supply (not shown in the figure) and the first indicator light (not shown in the figure) can be connected in series to the first interface and the second interface of the first continuity detector 400. Between the two interfaces, when the circuit between the first input interface 200 and the second input interface 300 in the junction box is connected, the circuit between the first input interface 200 and the second input interface 300 forms a closed loop with the first circuit power supply and the first indicator light, energizing the first indicator light and emitting a light signal as a connection indication. Conversely, when the circuit between the first input interface 200 and the second input interface 300 is disconnected, the circuit between the first input interface 200 and the second input interface 300 does not form a closed loop with the first circuit power supply and the first indicator light, preventing the first indicator light from being energized and emitting a light signal. Here, when the first continuity detector 400 issues a connection indication signal, relevant personnel can confirm that the circuit between the first input interface 200 and the second input interface 300 of the junction box is normally connected; when the first continuity detector 400 does not issue a connection indication signal, relevant personnel can confirm that the circuit between the first input interface 200 and the second input interface 300 of the junction box is abnormally disconnected.

[0037] Furthermore, the second continuity detector 500 is connected to the first input interface 200 and the first output interface 100 respectively. Here, in the actual test process, the first interface of the second continuity detector 500 can be connected to the first input interface 200, and the second interface of the second continuity detector 500 can be connected to the first output interface 100.

[0038] Furthermore, when the circuit between the first input interface 200 and the first output interface 100 in the junction box is connected, the second continuity detector 500 forms a connection loop with the circuit between the first input interface 200 and the first output interface 100, so that the second continuity detector 500 issues a connection prompt signal.

[0039] Here, the second continuity detector 500 includes a second circuit power supply (not shown in the figure) and a second indicator light (not shown in the figure). The second circuit power supply and the second indicator light can be connected in series between the first interface and the second interface of the second continuity detector 500. When the circuit between the first input interface 200 and the first output interface 100 in the junction box is connected, the circuit between the first input interface 200 and the first output interface 100 forms a continuous loop with the second circuit power supply and the second indicator light, so that the second indicator light is energized and emits a light signal as a continuity indication signal. Conversely, when the circuit between the first input interface 200 and the first output interface 100 is disconnected, the circuit between the first input interface 200 and the first output interface 100 does not form a continuous loop with the second circuit power supply and the second indicator light, so that the second indicator light cannot be energized and cannot emit a light signal. Here, when the second continuity detector 500 issues a continuity indication signal, the relevant personnel can confirm that the circuit between the first input interface 200 and the first output interface 100 of the junction box is normally connected. When the second continuity detector 500 does not issue a continuity indication signal, the relevant personnel can confirm that the circuit between the first input interface 200 and the first output interface 100 of the junction box is abnormally disconnected.

[0040] Furthermore, the third continuity detector 600 is connected to the second input interface 300 and the first output interface 100 respectively. Here, in the actual test process, the first interface of the third continuity detector 600 can be connected to the second input interface 300, and the second interface of the third continuity detector 600 can be connected to the first output interface 100.

[0041] Furthermore, when the circuit between the second input interface 300 and the first output interface 100 in the junction box is connected, the third continuity detector 600 forms a connection loop with the circuit between the second input interface 300 and the first output interface 100, so that the third continuity detector 600 issues a connection prompt signal.

[0042] Here, the third continuity detector 600 includes a third circuit power supply (not shown in the figure) and a fourth indicator light (not shown in the figure). The third circuit power supply and the fourth indicator light can be connected in series between the first interface and the second interface of the third continuity detector 600. When the circuit between the second input interface 300 and the first output interface 100 in the junction box is connected, the circuit between the second input interface 300 and the first output interface 100 forms a continuous loop with the third circuit power supply and the third indicator light, so that the third indicator light is energized and emits a light signal as a continuity indication signal. Conversely, when the circuit between the second input interface 300 and the first output interface 100 is disconnected, the circuit between the second input interface 300 and the first output interface 100 does not form a continuous loop with the third circuit power supply and the third indicator light, so that the third indicator light cannot be energized and cannot emit a light signal. Here, when the third continuity detector 600 issues a continuity indication signal, the relevant personnel can confirm that the circuit between the second input interface 300 and the first output interface 100 of the junction box is normally connected. When the third continuity detector 600 does not issue a continuity indication signal, the relevant personnel can confirm that the circuit between the second input interface 300 and the first output interface 100 of the junction box is abnormally disconnected.

[0043] This utility model provides a continuity detection device for a junction box. A first continuity detector is simultaneously connected to both the first and second input interfaces of the junction box. When the circuit between the first and second input interfaces within the junction box is connected, the first continuity detector, the first input interface, and the second input interface form a continuity loop, causing the first continuity detector to issue a continuity indication signal. Similarly, a second continuity detector is simultaneously connected to both the first input and first output interfaces of the junction box. When the circuit between the first input and first output interfaces within the junction box is connected, the second continuity detector, the first input interface, and the first output interface form a continuity loop, causing the second continuity detector to issue a continuity indication signal. Finally, a third continuity detector is simultaneously connected to both the second input and first output interfaces of the junction box. When the circuit between the second input and first output interfaces within the junction box is connected, the third continuity detector, the second input interface, and the first output interface form a continuity loop, causing the third continuity detector to issue a continuity indication signal. The technical solution provided in this application can detect the connectivity between every two interfaces of a junction box using a continuity detector, and issue a prompt message when the circuit between the two interfaces is connected, eliminating the need for manual continuity testing and thus improving the efficiency of continuity testing of the junction box.

[0045] Specifically, such as Figure 4 As shown, the first continuity detector includes a first power supply V1 and a first continuity indicator L1. The first end of the first continuity indicator L1 is connected to the first sub-input interface 210, the second end of the first continuity indicator L1 is connected to the negative terminal of the first power supply V1, and the positive terminal of the first power supply V1 is connected to the fourth sub-input interface 310. Here, when the circuit between the first sub-input interface 210 and the fourth sub-input interface 310 in the junction box is connected, the circuit between the first power supply V1, the first continuity indicator L1, and the first and fourth sub-input interfaces 210 forms a continuous loop. The first continuity indicator L1 is powered by the first power supply V1 and emits a green indicator light as a continuity signal to alert relevant personnel that the circuit between the first and fourth sub-input interfaces 210 and 310 in the junction box is connected. Conversely, when the circuit between the first and fourth sub-input interfaces 210 and 310 in the junction box is broken, the first continuity indicator L1 loses power and does not emit light.

[0046] Furthermore, the second continuity detector includes a second power supply V2, a third power supply V3, a second continuity indicator L2, and a third continuity indicator L3. The positive terminal of the second power supply V2 is connected to the second sub-input interface 220, the negative terminal of the second power supply V2 is connected to the first end of the second continuity indicator L2, and the second end of the second continuity indicator L2 is connected to the first sub-output interface 110.

The second continuity indicator L2 can emit a green indicator light as a continuity indication signal to remind relevant personnel that the circuit between the second sub-input interface 220 and the first sub-output interface 110 in the junction box is connected. Conversely, when the circuit between the second sub-input interface 220 and the first sub-output interface 110 in the junction box is disconnected, the second continuity indicator L2 loses power and does not illuminate.

[0047] Furthermore, the first end of the third connectivity indicator L3 is connected to the third sub-input interface 230, the second end of the third connectivity indicator L3 is connected to the positive terminal of the third power supply V3, and the negative terminal of the third power supply V3 is connected to the third sub-output interface 130. Here, when the circuit between the third sub-input interface 230 and the third sub-output interface 130 in the junction box is connected, the third power supply V3, the third connectivity indicator L3, and the circuit between the third sub-input interface 230 and the third sub-output interface 130 form a connected loop. The third connectivity indicator L3 is powered by the third power supply V3 and illuminates. The third connectivity indicator L3 can emit a green indicator light as a connectivity indication signal to remind relevant personnel that the circuit between the third sub-input interface 230 and the third sub-output interface 130 in the junction box is connected. Conversely, when the circuit between the third sub-input interface 230 and the third sub-output interface 130 in the junction box is broken, the third connectivity indicator L3 loses power and does not illuminate.

[0048] Furthermore, the third continuity detector includes a fourth power supply V4, a fourth continuity indicator L4, and a fifth continuity indicator L5.

Here, when the circuit between the fifth sub-input interface 320 and the second sub-output interface 120 in the junction box is connected, the fourth power supply V4, the fourth continuity indicator L4, and the circuit between the fifth sub-input interface 320 and the second sub-output interface 120 form a continuous loop. The fourth continuity indicator L4 is powered by the fourth power supply V4 and illuminates. The fourth continuity indicator L4 can emit a green indicator light as a continuity indication signal to remind relevant personnel that the circuit between the fifth sub-input interface 320 and the second sub-output interface 120 in the junction box is connected. Conversely, when the circuit between the fifth sub-input interface 320 and the second sub-output interface 120 in the junction box is broken, the fourth continuity indicator L4 loses power and does not illuminate.

[0049] Furthermore, the first end of the fifth connectivity indicator L5 is connected to the sixth sub-input interface 330, and the second end of the fifth connectivity indicator L5 is connected to the positive terminal of the third power supply V3.
