Description

Technical Field

[0001] The invention relates to an anti-loosening device and a method thereof, and in particular to a connector for fixing a nut to prevent loosening and a method thereof. Background Art

[0002] Micro rectangular electrical connectors like J30J are widely used in electromechanical products. The typical structure of this connector socket is a connector socket body with two locking components. The connector socket body is generally fixed to the electromechanical product with two locking components.

[0003] The typical structure of the locking assembly is: one end of the assembly is an internal threaded screw hole, and the other end is an external threaded screw. The connector socket body and the electromechanical product are designed with mounting holes for fixing. When fixing the connector socket body, pass one end of the screw of the locking assembly through the mounting holes of the connector socket body and the electromechanical product and then lock it with a nut. After the connector plug and the socket are plugged in, use the screw on the connector plug body to screw the screw hole at the other end of the locking assembly to strengthen the connection between the plug and the socket.

[0004] When removing the connector plug body, you need to loosen the screws on the connector plug first. During the loosening of the screws, the locking assembly that fixes the connector socket body will rotate along with the screws because it has no anti-rotation design. After multiple operations, the nut connected to the locking assembly will become loose, affecting the reliability of the connector socket body. Summary of the invention

[0005] The technical problem solved by the present invention is to provide a connector and method for fixing a nut to prevent loosening, which prevents the locking assembly from rotating along with the screw during loosening of the connector plug screw, and prevents relative rotation between the screw end of the locking assembly and the nut, thereby achieving the purpose of preventing the nut from loosening.

[0006] A fixed nut anti-loosening connector, comprising a connector socket body 1, a connector plug body 2, a locking assembly 3, a screw 4 and a nut 5;

[0007] The connector socket body 2 is fixed to the electromechanical product through the locking assembly 3; one end of the locking assembly 3 is an internal threaded screw hole, and the other end is an external threaded screw; the connector socket body 1 and the electromechanical product are both provided with mounting through holes; when fixing the connector socket body 1, one end of the screw of the locking assembly 3 passes through the mounting through holes of the connector socket body 1 and the electromechanical product and is then locked with a nut 5; after the connector plug is plugged into the socket, the screw 4 on the connector plug body 2 is used to screw the screw hole at the other end of the locking assembly 3;

[0008] Stopping planes are respectively arranged at corresponding positions of the mounting hole of the connector socket body 1 and the screw of the locking assembly 3 .

[0009] Furthermore, the stop planes designed at the corresponding positions of the mounting hole of the connector socket body 1 and the screw of the locking assembly 3 are respectively in a "milled flat" shape.

[0010] A method for preventing the fixing nut of the connector from loosening, comprising: a connector socket body 1 is fixed to an electromechanical product by a nut 5 through a locking assembly 3; after a connector plug body 2 is plugged into the connector socket body 1, a screw 4 is screwed into the screw hole of the locking assembly 3 for reinforcement; a stop plane is respectively designed at a corresponding position of the mounting hole on the connector socket body 1 and the screw of the locking assembly 3, and the two planes are fitted together during installation; when the connector plug body 2 needs to be disengaged from the connector socket body 1, the screw 4 used for reinforcement is loosened, and the stop planes fitted together prevent the locking assembly 3 from rotating with the screw 4.

[0011] The connector and anti-loosening method of the present invention respectively design a stop plane at the corresponding position of the mounting hole on the connector socket body and the screw of the locking assembly, and the two planes are fitted together during installation. When the screw is loosened, the stop planes that fit together can effectively prevent the locking assembly from rotating with the screw. Therefore, the fastening between the nut and the screw of the locking assembly is not affected, which greatly improves the reliability of the connector fixation. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the connector socket body and the connector plug body after being plugged into each other;

[0013] Figure 2 is Figure 1 Sectional view after cutting at cutting position.

[0014] In the figure: 1. Connector socket body 2. Connector plug body 3. Locking assembly 4. Screw 5. Nut DETAILED DESCRIPTION

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] like Figure 1 As shown, the connector socket body is fixed to the electromechanical product with a nut through a locking assembly. After the connector plug body and the connector socket body are inserted into each other, a screw is screwed into the screw hole of the locking assembly for reinforcement. When the connector plug body needs to be disengaged from the socket body, the screw used for reinforcement is loosened first. During the process of loosening the screw, the locking assembly will rotate with the screw due to the friction between the thread pairs. Therefore, the nut fixing the locking assembly will loosen.

[0017] The fixed nut anti-loosening connector provided by the present invention comprises a connector socket body 1, a connector plug body 2, a locking assembly 3, a screw 4 and a nut 5;

[0018] The connector socket body 2 is fixed to the electromechanical product through the locking assembly 3; one end of the locking assembly 3 is an internal threaded screw hole, and the other end is an external threaded screw; the connector socket body 1 and the electromechanical product are both provided with mounting through holes; when fixing the connector socket body 1, one end of the screw of the locking assembly 3 passes through the mounting through holes of the connector socket body 1 and the electromechanical product and is then locked with a nut 5; after the connector plug is plugged into the socket, the screw 4 on the connector plug body 2 is used to screw the screw hole at the other end of the locking assembly 3;

[0019] like Figure 2 As shown, in order to prevent the connector fixing nut from loosening, it is necessary to improve the design of the mounting through hole on the connector socket body and the screw of the locking assembly. A "milling flat" is designed on the mounting through hole and the screw to prevent the screw from rotating along its axis, that is, a stop plane is designed on the cylindrical surface of the mounting through hole and the screw. The two stop planes fit together, and during the installation and removal of the reinforcement screw on the connector plug, the locking assembly can be prevented from rotating with the screw.

[0020] The present invention also provides a method for preventing the fixing nut of a connector from loosening. The connector socket body 1 is fixed to the electromechanical product by a nut 5 through a locking assembly 3; after the connector plug body 2 is inserted into the connector socket body 1, a screw 4 is screwed into the screw hole of the locking assembly 3 for reinforcement; a stop plane is designed at the corresponding position of the mounting hole on the connector socket body 1 and the screw of the locking assembly 3, and the two planes are fitted together during installation; when the connector plug body 2 needs to be disengaged from the connector socket body 1, the screw 4 used for reinforcement is loosened, and the stop planes fitted together prevent the locking assembly 3 from rotating with the screw 4. Therefore, the fastening between the nut and the screw of the locking assembly is not affected, which greatly improves the reliability of the connector fixation.

[0021] The above description of the preferred embodiments of the present invention is merely exemplary in nature and is not intended to limit the present invention, its application or use. Therefore, the protection scope of the present invention is not limited to these schemes and details. Without departing from the basic principles of the present invention, those skilled in the art can make modifications or equivalent substitutions to these schemes and details, and the modified or substituted embodiments will also fall within the protection scope of the present invention.
