DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides an embodiment: a connector with sealing protection performance, including a connector 3, support devices 2 are fixedly installed at both ends of the connector 3, a protection device 1 is slidably installed between the two support devices 2, the protection device 1 includes an extension rod 4, a positioning key 5, an alignment groove 6, a magnetic strip 7 and an L-shaped protective cover 8, the alignment groove 6 is opened at the bottom of both ends of the L-shaped protective cover 8, the magnetic strip 7 is fixedly installed at the bottom of the front end of the L-shaped protective cover 8, the extension rod 4 is fixedly installed at the top of both ends of the L-shaped protective cover 8, and the positioning key 5 is fixedly installed at the bottom of the extension rod 4 away from the L-shaped protective cover 8.

[0021] The supporting device 2 includes a supporting side plate 9, an L-shaped alignment card plate 10, an extension base frame 11, a synchronization rod 12, a reset spring 13, a placement groove 14 and a handle 15. The placement groove 14 is opened at the top and bottom of the side end of the supporting side plate 9, and the reset spring 13 is symmetrically fixedly installed inside the placement groove 14. The handle 15 is fixedly connected to the end of the reset spring 13 away from the supporting side plate 9. The synchronization rod 12 is fixedly installed on the front end of the handle 15. The extension base frame 11 is fixedly installed on the end of the synchronization rod 12 close to the reset spring 13. The L-shaped alignment card plate 10 is fixedly installed on the opposite end of the extension base frame 11. By setting the handle 15, the L-shaped alignment card plate 10 can be driven to move.

[0022] The extension rod 4 and the positioning key 5 are slidably inserted into the side end of the supporting side plate 9 away from the handle 15. The supporting side plate 9 is fixedly installed at both ends of the connector 3 to support the handle 15 for operation.

[0023] The rear end of the L-shaped protective cover plate 8 fits with the front end surface of the connector 3 , which can improve the sealing performance of the L-shaped protective cover plate 8 to the connector 3 .

[0024] A sliding groove matching the extension rod 4 and the positioning key 5 is provided in the inner center of the supporting side plate 9 away from the handle 15. The extension rod 4 and the positioning key 5 slide in separate sliding grooves respectively, so that the L-shaped protective cover plate 8 can be prevented from falling off.

[0025] The L-shaped alignment card plate 10 is vertically aligned with the alignment groove 6 , so that the L-shaped alignment card plate 10 and the alignment groove 6 can be aligned and matched.

[0026] Working principle: When the connector 3 needs to be used, the L-shaped protective cover 8 can be pulled upward. When the L-shaped protective cover 8 is pulled upward to the limit position, the alignment groove 6 can be driven to be flush with the L-shaped alignment card plate 10. At this time, the elasticity of the reset spring 13 will drive the extension base 11 and the L-shaped alignment card plate 10 to reset, so that the raised part of the L-shaped alignment card plate 10 is inserted into the inside of the alignment groove 6, completing the limiting work of the L-shaped protective cover 8 and preventing the L-shaped protective cover 8 from falling downward. Subsequently, the connector 3 can be adapted to the external connector to complete the connector 3. The installation work is then done. Subsequently, when the connector 3 is not needed for a long time, the connector 3 can be removed from the external connection head, and the handle 15 can be pulled toward the end away from the supporting side plate 9, so that the protruding part of the L-shaped alignment card plate 10 can be moved out of the alignment groove 6, so that the L-shaped protective cover plate 8 can be released. Subsequently, the L-shaped protective cover plates 8 can be moved toward each other until the two magnetic strips 7 are adsorbed and fit together, so that the two L-shaped protective cover plates 8 can cover the side ends of the connector 3 for protection, and when the two magnetic strips 7 are moved to fit together, the L-shaped protective cover plates 8 are close to the connector 3. The two end corners of the near extension rod 4 can fit with the inner concave part of the L-shaped alignment card plate 10, so that the L-shaped alignment card plate 10 can limit the L-shaped protective cover 8 to prevent the L-shaped protective cover 8 from sliding again, thereby ensuring that the L-shaped protective cover 8 is always located in front of the connector 3 for dust prevention work. At the same time, when the L-shaped protective cover 8 slides, the extension rod 4 and the positioning key 5 respectively move in the sliding groove inside the side end of the supporting side plate 9 away from the handle 15, so that the L-shaped protective cover 8 can be ensured to move up and down in a straight line, lifting the alignment between the two L-shaped protective covers 8. Regarding connection accuracy, when the device is in use, when the L-shaped protective cover 8 is in a closed state, the 90° concave part of the L-shaped alignment card plate can be snapped on the two end corners of the L-shaped protective cover 8 to prevent the L-shaped protective cover 8 from being displaced again, thereby preventing external dust from entering the interior of the connector 3. At the same time, when the L-shaped protective cover 8 is in an open state, the raised part of the L-shaped alignment card plate 10 can be inserted into the alignment groove 6 to limit the L-shaped protective cover 8, thereby preventing the L-shaped protective cover 8 from falling off and completing the work.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
