Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically a locking device for connectors. Background Technology

[0002] Electrical connectors are common electrical components with a wide variety of specifications and types. Different types of electrical connectors are adapted to different types of electronic devices or instruments to connect circuits and achieve power transmission and signal transmission, playing an important role.

[0003] Electrical connectors used in electrical equipment still have some defects in use. After connection, they cannot effectively lock the two ends of the connector quickly, resulting in exposure. Or, under long-term vibration, the connector is prone to loosening, causing the electrical equipment to stop operating.

[0004] To address these issues, a novel locking device specifically designed for connectors is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a locking device specifically for connectors, in order to solve the problem mentioned in the background art of not being able to quickly lock the connectors.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a locking device for connectors, comprising a first connector, a first connector port fixedly connected to one side of the first connector, a second connector provided on one side of the first connector, a second connector port fixedly connected to one side of the second connector, the second connector port being movably connected to the first connector port, and a locking mechanism for automatic locking provided on the outside of the second connector.

[0007] The locking mechanism includes a connecting cylinder. The connecting cylinder is movably connected to the outside of the second connector. A set of fixing strips are fixedly connected to the same side of both ends of the connecting cylinder. Movable grooves are opened at both ends of the second connector. A fixing shaft is fixedly connected inside the movable groove. A spring is fixedly connected to one side of the movable groove. A set of fixing sleeves is fixedly connected to the other side of both ends of the connecting cylinder. Side grooves are opened at both ends of the first connector. A pressing plate is fixedly connected to one side of the side groove. A spring is fixedly connected to one side of the pressing plate. A positioning plate is fixedly connected to one side of one end of the spring. An anti-slip protrusion is fixedly connected to one end of the pressing plate.

[0008] As a further technical solution of this utility model, the positioning plate is movably connected to the fixing strip, and the fixing sleeve is slidably connected to the fixing shaft.

[0009] As a further technical solution of this utility model, the spring is fixedly connected to the fixed sleeve, and the fixed sleeve is slidably connected to the movable groove.

[0010] As a further technical solution of this utility model, the center line of the positioning plate and the center line of the fixing plate are on the same vertical plane, and the spring piece is movably connected to the fixing plate.

[0011] As a further technical solution of this utility model, a metal inner layer is fixedly connected inside the connecting cylinder.

[0012] As a further technical solution of this utility model, the center line of the inner metal layer and the center line of the connecting cylinder are on the same vertical plane, and the inner metal layer is movably connected to the second connecting head.

[0013] As a further technical solution of this utility model, a fixing cover is fixedly connected to one side of the first connector, and a shielding layer is fixedly connected inside the fixing cover. A groove is provided on one side of the second connector.

[0014] As a further technical solution of this utility model, the center line of the groove and the center line of the fixed cover are on the same vertical plane, and the fixed cover is movably connected to the groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the special locking device for connectors not only enables the connector to be locked quickly and effectively protects the connection, but also enables the connector to effectively shield against external interference during use.

[0016] The connector is equipped with a fixed sleeve, a fixed shaft, a movable groove, a connecting cylinder, a spring, a fixed strip, a pressing plate, a side groove, a spring piece, a positioning plate, and an anti-slip protrusion. When connecting the connector, the first connecting port is inserted into the inside of the second connecting port. Then, the connecting cylinder is pushed to fit over the outside of the first connecting head. At the same time, the fixed strip presses the positioning plate, causing the spring piece to deform. When the spring piece pops out quickly, the positioning plate engages with the fixed strip, thereby positioning the connecting cylinder through the fixed strip. When disassembly is required, pressing the pressing plate causes the spring piece to retract, causing the positioning plate to disengage from one side of the fixed strip. The spring can then quickly push the connecting cylinder back through the fixed sleeve, thus achieving quick locking of the connector.

[0017] By incorporating a second connector, a connecting sleeve, and a metal inner layer, the connector, after connection, fits the connecting sleeve over the outside of the first connector. Simultaneously, the connecting sleeve covers the outside of both the first and second connection ports. The connecting sleeve effectively protects both, and the metal inner layer inside the connecting sleeve enhances its strength, thereby effectively improving the protection of the connector.

[0018] By incorporating a groove, a retaining cover, and a shielding layer, when the connector is connected, the first connector port is inserted into the second connector port, and the retaining cover on one side of the first connector head is inserted into the groove on one side of the second connector head. The shielding layer inside the retaining cover can effectively shield external electrical signals to prevent external electrical signals from interfering with the connector's signal transmission.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, when connecting the connector, the first connection port 2 is inserted into the inside of the second connection port 3, and then the connecting cylinder 8 is pushed to fit onto the outside of the first connector 1. At the same time, the fixing plate 12 squeezes the positioning plate 18, causing the spring piece 17 to deform. Then, when the spring piece 17 pops out quickly, the positioning plate 18 engages with the fixing plate 12, thereby positioning the connecting cylinder 8 through the fixing plate 12.

[0037] Working Principle: In use, when connecting the connector, the first connecting port 2 is inserted into the interior of the second connecting port 3. Then, the connecting cylinder 8 is pushed to fit over the outside of the first connecting head 1. Simultaneously, the fixing plate 12 presses against the positioning plate 18, causing the spring piece 17 to deform. When the spring piece 17 quickly pops out, the positioning plate 18 engages with the fixing plate 12, thus positioning the connecting cylinder 8. To disassemble, pressing the pressing plate 15 causes the spring piece 17 to retract, disengaging the positioning plate 18 from one side of the fixing plate 12.
