Description

Technical Field

[0001] This utility model relates to the field of photovoltaic connector technology, specifically a photovoltaic connector with current detection function. Background Technology

[0002] As is well known, in photovoltaic systems, connectors are key components that ensure electrical connections between solar panels and between solar panels and other equipment such as inverters. With the development of solar power generation technology and the continuous expansion of its application scale, the requirements for connector performance are becoming increasingly stringent, especially in terms of safety, stability, and ease of maintenance. Traditional photovoltaic connectors mainly focus on achieving good electrical connections, but in actual operation, they cannot monitor the current flowing through the connector in real time. This limitation may lead to the following problems: if an overcurrent occurs and is not detected in time, it may cause the cable to overheat or even catch fire. When a system fault occurs, such as a short circuit, it is difficult to quickly locate the specific location, increasing the difficulty and time cost of maintenance. Although many existing designs have taken measures to improve the tightness of connectors, they often rely on simple plug-and-play mechanisms or screw fixing methods. These methods may not be sufficient to cope with the long-term effects of factors such as vibration and temperature changes in the outdoor environment, which may cause loosening or other forms of poor contact, affecting the normal operation of the system. Therefore, we propose a photovoltaic connector with current detection function to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] like Figure 1-5 As shown in the figure, an embodiment of the present invention discloses a photovoltaic connector with current detection function, including a photovoltaic connector male head 1 and a photovoltaic connector female head 2. A Hall effect current sensor 3 is fixedly mounted on the surface of the photovoltaic connector male head 1. A mounting box 4 is fixedly mounted on the surface of the Hall effect current sensor 3. A first line connector 5 is fixedly mounted on the surface of the mounting box 4. The first line connector 5 is electrically connected to the Hall effect current sensor 3. A fixing box 6 is fixed on the other side surface of the mounting box 4. A screw 7 is rotatably mounted inside the fixing box 6 via a bearing. One end of the screw 7 passes through one side wall of the fixing box 6 and is fixed with a knob 16. The surface of the knob 16 is provided with anti-slip texture, which can play a good anti-slip role, thereby facilitating the operator to rotate it. The other end of the screw 7 passes through the other side wall of the fixing box 6. The screw 7 is threadedly connected to a slider 8 on one side wall of the mounting box 4 and extends into the mounting box 4. A wedge 9 is fixed to one side wall of the slider 8. The slider 8 and the wedge 9 are slidably connected in the mounting box 4. A stop 14 is fixed to the top of the screw 7 to prevent the slider 8 from coming off the top of the screw 7. A second line connector 10 that is compatible with the first line connector 5 is fixed to the surface of the photovoltaic connector female head 2. A mating block 11 is fixed to the surface of the second line connector 10. A wedge groove is opened on the surface of the mating block 11. A socket 12 that is compatible with the mating block 11 is opened on the surface of the first line connector 5. The socket 12 communicates with the mounting box 4. The wedge 9 is compatible with the wedge groove on the mating block 11. A locking control component 13 for locking the screw 7 is provided on the fixing box 6.

[0024] When it is necessary to connect the photovoltaic connector male 1 and the photovoltaic connector female 2 together, align the photovoltaic connector female 2 with the photovoltaic connector male 1 and insert it. When the two are fully inserted, the first line connector 5 is also inserted with the second line connector 10, thus enabling the Hall effect current sensor 3 and the photovoltaic connector to be connected to the line simultaneously. At this time, the mating block 11 will pass through the socket 12 and enter the mounting box 4. Then, the operator operates the locking control component 13 with one hand to release the lock on the screw 7, and with the other hand, can turn the knob 16. The knob 16 can drive the screw 7 to rotate, and the screw 7 can drive the slider 8 on its surface to move upward. The slider 8 can drive the... The inclined block 9 moves upward, thus engaging with the inclined groove of the mating block 11. This fixes the male photovoltaic connector 1 and the female photovoltaic connector 2 together, as well as the first line connector 5 and the second line connector 10 together. Then, the operator operates the locking control component 13 to lock the screw 7, preventing the screw 7 from rotating without operator intervention. This avoids loosening of the male photovoltaic connector 1 and the female photovoltaic connector 2, preventing poor contact and ensuring connection quality during long-term operation. The use of the Hall effect current sensor 3 to detect the current of the photovoltaic connector further enhances safety.

[0025] like Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, the locking control assembly 13 includes a slide plate 1301 slidably mounted inside the fixed box 6. A spring 1302 is fixed to one side wall of the slide plate 1301, and one end of the spring 1302 is fixedly connected to the inner wall of the side adjacent to the fixed box 6. A toothed post 1303 is fixedly fixed through the interior of the slide plate 1301. One end of the toothed post 1303 slidably passes through one side wall of the fixed box 6 and is fixed with a pull block 1304. The other end of the toothed post 1303 is engaged with a gear 1305, which is sleeved and fixed on the surface of the screw 7. When the operator needs to rotate the screw 7, the locking of the screw 7 can be released. The unlocking operation is to pull the pull block 1304 outward. 4 can drive the toothed column 1303 to move outward, so that the end of the toothed column 1303 will disengage from the tooth groove of the gear 1305, and the screw 7 can rotate. When the toothed column 1303 moves outward, it will drive the slide plate 1301 to move outward, and the slide plate 1301 will compress the spring 1302. When it is necessary to prevent the screw 7 from rotating and to lock the screw 7, release the pull block 1304. Under the elastic force of the spring 1302, it will drive the slide plate 1301 to move inward, so that the end of the toothed column 1303 can engage with the tooth groove of the gear 1305, thus locking the screw 7. Therefore, when encountering vibration or non-operational conditions, the screw 7 will not easily rotate.

[0026] like Figure 1 and Figure 2 As shown, in some embodiments, a rubber sealing strip 15 is fixed to the inner sidewalls of the first line connector 5. The purpose of setting the rubber sealing strip 15 is to improve the sealing performance when the first line connector 5 and the second line connector 10 are inserted.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
