Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a rapid polarity conversion device of a double-core connector. Background Art

[0002] In the field of optical communication and data transmission, the dual-core connector is an important connection component, and the convenience and safety of its polarity conversion are crucial to the stable operation of the system.

[0003] When performing polarity conversion operations on a dual-core connector, it is necessary to remove the pressure plate or the shell of the dual-core connector to interchange the connection positions of the two connector components, thereby achieving the conversion of the polarity of the dual-core connector. However, the above operation is not only cumbersome and the disassembly process is complicated, but also the crimping part of the cable may be damaged due to improper operation, affecting the stability of the connection and the quality of data transmission. Moreover, the removed parts such as the pressure plate or the shell are easily separated from the connector body, which may be lost, causing inconvenience to subsequent maintenance and use. Summary of the invention

[0004] In view of the above problems existing in the existing two-core connector, a rapid polarity conversion device for the two-core connector is now provided.

[0005] The specific technical solutions are as follows:

[0006] A quick polarity conversion device for a dual-core connector, the dual-core connector comprising a main body component and two connector components that can be detached from the main body component in the longitudinal direction, comprising: a pressing plate, the pressing plate having a suspension shaft, a fixed claw and a hinge shaft arranged between the suspension shaft and the fixed claw, the main body component being provided with a card slot, a hinge hole and a suspension hole in sequence in the left-right direction, the suspension shaft being rotatably arranged in the suspension hole, and the size of the suspension hole being larger than the size of the suspension shaft, so that the suspension shaft can move left-right and up-down;

[0007] Among them, the top of the main body component has an open groove connected to the side of the hinge hole away from the hanging hole. When assembling, the hinge shaft is rotated in the hinge hole and the fixed claw is engaged in the groove, so that the pressure plate presses and locks the two connector components. When unlocking, the pressure plate is pushed to the left to disengage the fixed claw from the groove and the hinge shaft is moved to the open groove. The pressure plate is flipped up again to disengage the hinge shaft from the open groove, thereby releasing the pressure and lock of the two connector components.

[0008] As a further improvement and optimization of the present solution, the left bottom of the pressure plate has an elastic structure, and the pressure plate is elastically pressed against the two connector components through the elastic structure.

[0009] As a further improvement and optimization of this solution, the elastic structure is a suspension elastic sheet.

[0010] As a further improvement and optimization of this solution, the hinge hole is a "D"-shaped hole.

[0011] As a further improvement and optimization of this solution, the groove width of the opening slot is greater than the diameter of the hinge shaft.

[0012] As a further improvement and optimization of this solution, the suspension hole is a "heart"-shaped hole, which includes an unlocking section and a locking section that are interconnected.

[0013] The longitudinal groove width of the card slot is greater than the thickness of the fixed claw.

[0014] When the fixed claw is located in the card slot and is in limit fit with the top inner wall of the card slot, the suspension shaft is located at the bottom of the locking section and is in transverse limit fit with the locking section.

[0015] When the fixed claw is located in the card slot and is in limit fit with the bottom inner wall of the card slot, the suspension shaft is located at the connection between the locking section and the unlocking section.

[0016] When the fixed claw disengages from the card slot and the hinge shaft moves into the opening slot, the suspension shaft is located in the unlocking section and is in limit fit with the left inner wall of the unlocking section.

[0017] As a further improvement and optimization of this solution, the connector assembly is a simplex LC connector assembly.

[0018] As a further improvement and optimization of this solution, there are two suspension elastic sheets, which are respectively located on both sides of the pressing plate and are used to elastically press the two connector assemblies respectively.

[0019] The positive effects of the above technical solution compared with the prior art are as follows:

[0020] (1) When performing polarity conversion in the present invention, by pushing the pressing plate to the left, the fixed claw is disengaged from the card slot and the hinge shaft moves into the opening slot. Then, by flipping the pressing plate upward, the hinge shaft is disengaged from the opening slot, so that the pressing plate releases the pressing and locking of the two connectors. Then, the two connector assemblies are pulled out of the main body assembly upward, interchanged in position, and then reinstalled on the main body assembly to complete the polarity conversion operation. Finally, the pressing plate is flipped downward to the initial horizontal state, and the pressing plate is pushed to the right so that the hinge shaft slides into the hinge hole and the fixed claw is reinserted into the card slot, and the connector returns to the normal assembled state. The operation is simple and fast, effectively avoiding damage to the crimped part of the cable due to improper operation.

[0021] (2) In the utility model, a suspension shaft is provided on the pressure plate and a suspension hole larger than the suspension shaft is provided on the main component. When the pressure plate is unlocked, the suspension shaft moves in the suspension hole so that the pressure plate is always connected to the main component, thereby effectively avoiding the risk of losing the pressure plate.

[0022] (3) In the utility model, when the pressure plate is in the assembled state and the two connector components are pressed and locked, the fixed claw is located in the slot and cooperates with the top inner wall limit of the slot, and the suspension shaft is located at the bottom of the locking section and cooperates with the lateral limit of the locking section to avoid accidental contact with the pressure plate, which causes the pressure plate to move to the left and cause the fixed claw to disengage from the slot, thereby improving the stability of the connector connection.

Then, the two connector components 2 are pulled upward out of the main body component 1, interchanged and reset to the main body component 1 to complete the polarity conversion operation. Finally, the pressure plate 3 is flipped down to the initial horizontal state and pushed to the right to allow the hinge shaft 31 to slide into the hinge hole 12 and the fixed claw 33 to be re-engaged in the card slot 11. The connector returns to a normal assembly state. The operation is simple and quick, and improper operation can effectively avoid damage to the crimped part of the cable.
