Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a connector with an automatic power-off function. Background Technology

[0002] Connectors are indispensable basic components in electronic, electrical, or optical signaling systems. Their core function is to establish a reliable and repeatable electrical, signal, or optical path between two separate subsystems, devices, or circuits, enabling power transfer, signal transmission, or data exchange. They essentially act as a "bridge," allowing complex systems to be assembled, maintained, and upgraded through modular design. A typical connector consists of mating plugs and sockets, containing critical conductive contacts for forming current or signal paths, an insulator to ensure electrical isolation and mechanical support between contacts, and a housing providing protection, shielding, and locking functions. Connector performance is crucial, with key considerations including the safe current / voltage range it can withstand, contact resistance, insulation resistance, mechanical life, environmental tolerance, and signal transmission rate / bandwidth.

[0003] To ensure the reliable function of connectors, some connectors integrate circuit breakers, which automatically disconnect the circuit in case of short circuits or overloads. To ensure the normal and safe operation of the circuit breaker, a protective cover is required around it. However, in existing connectors with automatic power-off functions, the structure of the circuit breaker protective cover is mostly complex with many parts, making it inconvenient to quickly open the protective cover for circuit breaker maintenance. Therefore, a connector with automatic power-off function is proposed to solve the problems mentioned above. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a connector with an automatic power-off function, which has advantages such as ease of opening. It solves the problem that existing connectors with automatic power-off functions and circuit breaker protective covers mostly have many complex parts, making it inconvenient to quickly open the protective cover for circuit breaker maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a connector with automatic power-off function, comprising a connector body, a connector end provided with a joint, a circuit breaker fixedly installed on one side of the connector body, and a protective component provided on the outside of the circuit breaker;

[0006] The protective assembly includes a protective cover fitted over the circuit breaker. Positioning components are provided on both the upper and lower sides of the protective cover. A connecting rod is fixedly connected to the side of the protective cover away from the connector. A fixing box is provided at the end of the connecting rod away from the protective cover. An elastic component is provided between the connecting rod and the fixing box.

[0007] The positioning component includes a fixing plate fixedly connected to the outer wall of the connector body and a connecting seat fixedly connected to the outer wall of the protective cover. A locking block is movably installed on the outer side of the connecting seat, and two slots adapted to the locking block are opened on the outer wall of the fixing plate.

[0008] Furthermore, the elastic component includes a support plate disposed inside the fixing box, and a spring is disposed on the side of the support plate away from the connecting rod, and the end of the spring away from the support plate is in contact with the inner wall of the fixing box.

[0009] Furthermore, the end of the connecting rod away from the protective cover is inserted into the inside of the fixing box and is fixedly connected to the outer wall of the support plate.

[0010] Furthermore, the support plate slides in conjunction with the inner wall of the fixing box, and the fixing box is fixedly connected to the outer wall of the connector body.

[0011] Furthermore, a rotating shaft is rotatably mounted on the inner side of the connecting seat, and the locking block is fixedly connected to the outer wall of the rotating shaft.

[0012] Furthermore, the outer wall of the card block is provided with protrusions, and the protective cover is open on the side near the connector.

[0013] Furthermore, a groove is provided on the side of the fixing plate near the protective cover, and a slider is provided on the protective cover near the groove, the slider being slidably connected to the inside of the groove.

[0014] Compared with the prior art, the present invention provides a connector with an automatic power-off function, which has the following advantages:

[0015] This connector with automatic power-off function uses a locking block that engages with a slot near the circuit breaker to lock the protective cover around the circuit breaker and provide protection. When maintenance is required, the locking block is rotated by moving the protrusion, separating it from the fixing plate. The protective cover is then slid along one side of the fixing box, aligning the locking block with a slot away from the circuit breaker. The locking block is then engaged with that slot, fixing the protective cover away from the circuit breaker for easy maintenance. This design allows for convenient opening and closing and avoids the protective cover resetting and re-obstructing the circuit breaker after opening. It also facilitates maintenance and solves the problem that existing connectors with automatic power-off function often have complex and multi-part protective covers, making it difficult to quickly open the protective cover for circuit breaker maintenance.

[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] Please see Figures 1 to 4 This embodiment of a connector with automatic power-off function includes a connector body 1, a connector 2 at the connecting end of the connector body 1, a circuit breaker 3 fixedly installed on one side of the connector body 1, a protective component on the outside of the circuit breaker 3, the protective component including a protective cover 4 sleeved on the outside of the circuit breaker 3, the protective cover 4 being open on the side near the connector 2, positioning components on both the upper and lower sides of the protective cover 4, a connecting rod 12 fixedly connected to the side of the protective cover 4 away from the connector 2, a fixing box 11 being provided at the end of the connecting rod 12 away from the protective cover 4, the fixing box 11 being fixedly connected to the outer wall of the connector body 1, and an elastic component being provided between the connecting rod 12 and the fixing box 11.

[0023] In this embodiment, the positioning component includes a fixing plate 5 fixedly connected to the outer wall of the connector body 1 and a connecting seat 6 fixedly connected to the outer wall of the protective cover 4. A locking block 7 is movably installed on the outer side of the connecting seat 6. Two slots 8 adapted to the locking block 7 are opened on the outer wall of the fixing plate 5. The two slots 8 are spaced a certain distance apart. When the locking block 7 cooperates with the slot 8 near the circuit breaker 3, the protective cover 4 can be locked around the circuit breaker 3 to provide protection. When the locking block 7 cooperates with the slot 8 away from the circuit breaker 3, the protective cover 4 can be fixed at a position away from the circuit breaker 3, which facilitates the maintenance of the circuit breaker 3.

[0024] It should be noted that a rotating shaft 9 is rotatably mounted on the inner side of the connecting seat 6, and a locking block 7 is fixedly connected to the outer wall of the rotating shaft 9. A protrusion 10 is provided on the outer wall of the locking block 7, which facilitates the movement of the locking block 7 and makes operation easier.

[0025] It should be noted that a groove is provided on the side of the fixed plate 5 near the protective cover 4, and a slider is provided on the protective cover 4 near the groove. The slider is slidably connected to the inside of the groove. The cooperation between the slider and the groove can guide the protective cover 4, so that the protective cover 4 can maintain a stable movement trajectory and improve stability.

[0026] In this embodiment, the elastic component includes a support plate 13 disposed inside the fixed box 11. The support plate 13 is slidably engaged with the inner wall of the fixed box 11. A spring 14 is disposed on the side of the support plate 13 away from the connecting rod 12. The end of the spring 14 away from the support plate 13 is in contact with the inner wall of the fixed box 11. The end of the connecting rod 12 away from the protective cover 4 is inserted into the fixed box 11 and is fixedly connected to the outer wall of the support plate 13.

[0027] Understandably, when the protective cover 4 moves, it can push the support plate 13 to move through the connecting rod 12 and squeeze the spring 14. When the locking block 7 releases the lock on the protective cover 4, the spring 14 can release its elastic force to reset the protective cover 4. After the protective cover 4 is reset, it can return to the vicinity of the circuit breaker 3 and play a protective role.

[0028] The working principle of the above embodiments is as follows:

[0029] In use, the locking block 7 engages with the slot 8 near the circuit breaker 3 to lock the protective cover 4 around the circuit breaker 3 and provide it with protection. When maintenance of the circuit breaker 3 is required, the protrusion 10 is moved to rotate the locking block 7, causing it to separate from the fixing plate 5. Then, the protective cover 4 is slid along one side of the fixing box 11 so that the locking block 7 corresponds to the slot 8 away from the circuit breaker 3. The locking block 7 is then engaged with the slot 8 at that location to fix the protective cover 4 in a position away from the circuit breaker 3, so as to facilitate maintenance of the circuit breaker 3.

[0030] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented. Furthermore, the electrical components appearing in this embodiment are all existing publicly available power connection technologies, which are common knowledge in the field. Therefore, their specific structural composition and working principles will not be described in detail here.
