Technical Field

[0001] The utility model relates to the technical field of crown spring connectors, and more specifically to a miniature crown spring connector. Background Art

[0002] The crown spring connector is a common electrical connector, usually used for circuit board connections in electronic equipment. The crown spring has the characteristics of high reliability, soft pull-out force, low contact resistance, shock resistance, and impact resistance.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0026] See also Figures 1 to 4In the utility model: a miniature crown spring connector comprises a protective sleeve 1, a crown spring body 2 is installed on the inner wall of the protective sleeve 1, a protective sleeve 3 fixedly connected to the protective sleeve 1 is sleeved on the protective sleeve 1, an air bag 4 is embedded on the inner side of the protective sleeve 3, the air bag 4 is annular in shape, a cavity 5 is opened on the inner wall of the protective sleeve 3, the cross-sectional shape of the cavity 5 is annular, two conduits 6 are connected to the inner wall of the cavity 5, and the opposite ends of the two conduits 6 are connected to the air bag 4, a piston plate 7 is slidably connected to the inner wall of the cavity 5, and a sliding rod 8 distributed in an annular manner is fixedly connected to the right side of the piston plate 7, and the right end of the sliding rod 8 passes through and extends to the right side of the protective sleeve 3, and a moving ring 9 threadedly connected to the protective sleeve 1 is sleeved on the protective sleeve 1.

[0027] When the plug is in use, the pin is inserted from the left side of the protective sleeve 1. After the plug is in the protective sleeve 1, its surface will be in close contact with the crown spring body 2, thereby completing the connection. After the connection is completed, the user rotates the moving ring 9, and the moving ring 9 will move to the left along the outer side of the protective sleeve 1. During the process, the sliding rod 8 will be inserted into the cavity 5 on the protective sleeve 3. When the sliding rod 8 is inserted into the cavity 5, it will drive the piston plate 7 to slide along the inner wall of the cavity 5. At this time, the air inside the cavity 5 will be squeezed, and the gas will enter the airbag 4 from the conduit 6. The airbag 4 will then expand, and the inner side of the airbag 4 will then move toward the plug until the airbag 4 is in close contact with the plug. At this time, the plug and the protective sleeve 1 will be sealed by the cooperation of the protective sleeve 3 and the airbag 4, thereby effectively preventing dust or moisture from entering the protective sleeve 1 during the connection process, thereby improving the stability of the connection between the plug and the crown spring body 2, and improving the stability of the connector when in use.

[0028] See also Figure 4 , wherein: a mounting groove 10 is provided at the right end of the slide rod 8, and a ball bearing 11 is movably connected to the inner wall of the mounting groove 10.

[0029] In the utility model, the provision of the ball 11 can reduce the friction between the slide bar 8 and the moving ring 9, making it easier for the user to rotate the moving ring 9 to push the slide bar 8, while reducing wear and increasing the service life of the device.

[0030] See also Figures 1 to 3 , wherein: the moving ring 9 is fixedly connected with an annularly distributed anti-sliding block 12, and the anti-sliding block 12 is square in shape.

[0031] In the present invention, the provision of the anti-sliding block 12 can increase the friction of the moving ring 9, thereby facilitating the user to rotate the moving ring 9, thereby improving the practicability of the device.

[0032] See also Figure 4 , wherein: the inner wall of the cavity 5 is connected with an exhaust pipe 13 , and the bottom end of the exhaust pipe 13 passes through and extends to the inside of the protective cover 1 .

[0033] In the utility model, when the piston plate 7 slides inside the cavity 5, the air inside the cavity 5 will enter the protective sleeve 1 from the exhaust pipe 13, and the air will be discharged from the left end of the protective sleeve 1. The air will blow off the dust on the surface of the protective sleeve 1 and the plug during the flow, thereby achieving the effect of cleaning the plug, thereby improving the practicality of the device, until the piston plate 7 slides over the top of the exhaust pipe 13, at which time the air inside the cavity 5 will be pressed into the airbag 4 to drive it to expand.

[0034] See also Figures 1 to 4 , wherein: a sealing rod 14 threadedly connected to the top of the protective sleeve 3 is inserted through the top, and the bottom end of the sealing rod 14 contacts the inner wall of the exhaust pipe 13 .

[0035] In the utility model, the setting of the sealing rod 14 can seal the exhaust pipe 13 during the initial sliding of the piston plate 7. At this time, the gas inside the cavity 5 will have a certain pressure. When the piston plate 7 moves to be about to contact the sealing rod 14, the user quickly rotates the sealing rod 14, and the sealing rod 14 will be pulled out of the exhaust pipe 13. The pressurized gas will quickly enter the protective cover 1, thereby improving the cleaning effect of the pin and the protective cover 1.

[0036] See also Figures 1 to 4 , wherein: an annular groove 15 is opened at the left end of the protective sleeve 3, and an annular clamping rod 16 is inserted into the inner wall of the annular groove 15, and the outer side of the clamping rod 16 is threadedly connected to the protective sleeve 3.

[0037] In the present invention, after the pin is sealed, the user rotates the clamping rod 16, and the clamping rod 16 moves toward the insulating portion of the pin until the clamping rod 16 is in close contact with the insulating portion of the pin, thereby locking the pin and improving the stability of the connection.

[0038] The above are only preferred specific implementations of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
