Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and specifically to a connector that simultaneously has a locking function and an unlocking assistance separation function. Background Art

[0002] In connectors, the rectangular connector plug and socket are generally locked by screws. During the locking process, a screwdriver is used to turn the screw for locking. When unlocking, a screwdriver is also required to turn the screw until the screw is completely unscrewed to achieve connector unlocking, and then the plug and socket are manually separated. If the unlocking force of the connector is large, some connectors are provided with a boosting structure to facilitate connector unlocking. As shown in Figure 1 and Figure 2 The connector is locked by tightening the screw and the threaded hole. When unlocking the connector, first use a screwdriver to unscrew the screw, and then rotate the boosting mechanism clockwise along the rotation axis through the boosting mechanism, so as to achieve the purpose of assisting the separation of the plug and socket. However, the existing unlocking and boosting mechanisms have a sequential operation order. The thread must be loosened first, and then the boosting mechanism is used for separation. If the boosting mechanism is forcibly used to unlock when the thread is not loosened, it may cause damage to the boosting mechanism. In addition, the locking method of using installation screws to lock the plug and socket is inconvenient to use, the number of rotations of the installation screw is large, and the assembly efficiency is low. Summary of the Invention

[0003] To overcome the defects of the above-mentioned prior art, the present invention provides a connector that simultaneously has a locking function and an unlocking assistance separation function. The locking mechanism on the connector simultaneously has the functions of locking and unlocking assistance separation. The unlocking and locking processes of the connector are simple and efficient. The unlocking and assistance separation have a fixed sequence through the locking mechanism, without the risk of incorrect operation, and avoid damage to the boosting mechanism caused by incorrect operation.

[0004] The present invention solves its technical problems by adopting the following technical solutions. A connector that simultaneously has a locking function and an unlocking assistance separation function according to the present invention includes a plug and a socket that is inserted into the plug. The socket is provided with a locking post, and the plug is provided with a through hole for the locking post to penetrate and a locking assistance mechanism pivotally connected to the plug. The locking assistance mechanism is provided with a first protrusion for cooperating with a groove on the locking post for locking. The locking assistance mechanism can rotate around a connection axis pivotally connected to the plug. The locking assistance mechanism simultaneously has the functions of unlocking and assistance separation. When the head and socket are separated, the locking assistance mechanism rotates around the connection axis to separate the first protrusion from the groove on the locking post to achieve unlocking. When the locking assistance mechanism continues to rotate around the connection axis in the same direction, the right end of the locking assistance mechanism abuts against the socket mounting panel to separate the head and socket, thereby playing a role in assisting separation.

[0005] Further, the mating and locking surfaces of the first protrusion and the groove are both conical surfaces or arc-shaped surfaces and the mating and locking surfaces of the first protrusion and the groove are adapted to each other.

[0006] Further, the leading-in ends of the first protrusion and the groove are both arc-shaped transitions so that the first protrusion can be smoothly snapped into the groove.

[0007] Further, an elastic arm is also provided on the plug for cooperating with the second protrusion on the locking assist mechanism to achieve further locking; when the head and the socket are separated, the locking assist mechanism rotates around the connecting shaft to separate the first protrusion from the groove on the locking post, and at the same time separates the second protrusion from the elastic arm to achieve unlocking.

[0008] Furthermore, an arc-shaped third protrusion is provided at the locking end of the second protrusion for cooperating with the hook claw provided on the elastic arm to achieve locking.

[0009] Furthermore, the second protrusion is provided above the first protrusion, and the elastic arm is provided above the through hole.

[0010] Further, clockwise rotation of the locking assist mechanism is for unlocking, and counterclockwise rotation is for locking.

[0011] Further, the locking post is provided on the plug, and the locking assist mechanism and the through hole for the locking post to pass through are provided on the socket.

[0012] Furthermore, an elastic arm is also provided on the socket for cooperating with the second protrusion on the locking assist mechanism to achieve further locking; when the head and the socket are separated, the locking assist mechanism rotates around the connecting shaft to separate the first protrusion from the groove on the locking post, and at the same time separates the second protrusion from the elastic arm to achieve unlocking.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] The locking mechanism of the present invention has the functions of locking, unlocking and assisting separation at the same time. When the head and the socket are separated, it is necessary to rotate for unlocking first and then rotate for assisting separation. There is a sequence for unlocking, and the rotation unlocking process must be passed through before assisting separation. Since the acting force directions applied to the locking assist mechanism during unlocking and assisting separation are the same, under the external force, the locking assist mechanism must first pass through unlocking before performing assisting separation, which can prevent misoperation and avoid the situation in the prior art where the assisting mechanism is damaged when the screw is not completely unscrewed. At the same time, compared with the original screw locking mechanism, the locking and unlocking mechanisms of the present invention are simple to operate, have high efficiency, save working hours, and can prevent misoperation, and are a convenient and practical new design.

Detailed Implementation Manner

[0025] To further elaborate on the technical means and technical effects adopted by the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] It should be noted that: The terms indicating directions such as "above", "right end", "clockwise", "counterclockwise", etc. in the present invention are all based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention, and therefore cannot be construed as a limitation to the present invention.

[0027] Such as Figure 3As shown in the figure, the connector of the present invention includes a plug 1 and a socket 2 that mates with the plug. A locking post 4 is provided on the socket mounting panel 3, and a locking mechanism is provided at one end of the plug for cooperating with the locking post to achieve locking. Specifically, the locking mechanism on the plug includes a connection block 5 integrally connected to one end of the plug, a locking assist mechanism 6 pivotally connected to the connection block, and an elastic arm 7 disposed above the connection block and integrally connected to the plug with a certain elasticity. A through hole 8 is provided on the connection block near one end of the plug for the locking post to pass through. The elastic arm is disposed above the through hole, with one end connected to the plug and the other end provided with a downwardly curved hook 9. The locking assist mechanism 6 pivotally connected to the connection block is provided with a first protrusion 11 for cooperating with the groove 10 on the locking post to lock and a second protrusion 12 for cooperating with the elastic arm for further locking. The mating locking surfaces 13 of the first protrusion and 14 of the groove are both conical surfaces or arc surfaces, and the mating locking surface 13 of the first protrusion is adapted to the mating locking surface 14 of the groove. The leading ends 15 of the first protrusion and 16 of the groove are both arc transitions, so that the first protrusion can be smoothly snapped into the groove. The locking end of the second protrusion is provided with an arcuate third protrusion 17 for cooperating with the hook of the elastic arm for further locking. The second protrusion is disposed above the first protrusion.

[0028] The described locking assist mechanism simultaneously has the functions of locking, unlocking, and assisting separation, and it can rotate around a connection shaft 18 pivotally connected to the connection block. Figure 3 As shown in the example, clockwise rotation of the locking assist mechanism is for unlocking, and counterclockwise rotation is for locking.

[0029] Taking Figure 3 、 Figure 7 and Figure 8 as examples, the locking, unlocking, and assisting separation principles of the present invention will be described in detail:

[0030] Figure 3 The shown locking post is provided on the socket mounting panel, and the locking mechanism is provided at one end of the plug. When the plug and socket are inserted together, the locking post is inserted into the through hole on the connection block and the groove on the locking post is exposed, as Figure 7 shown. After the plug and socket are inserted together, apply a force to the locking assist mechanism in the counterclockwise direction. The locking assist mechanism rotates counterclockwise around the connection shaft, and finally the leading end of the first protrusion and the leading end of the groove cooperate to make the first protrusion snap into the groove on the locking post to achieve locking. At the same time, the third protrusion on the locking end of the second protrusion snaps into the hook of the elastic arm to achieve further locking, as Figure 8 shown.

[0031] When the head and socket need to be separated, it is necessary to unlock first and then separate. Specifically, apply a force to the locking assist mechanism in the clockwise direction first to make the locking assist mechanism rotate clockwise around the connecting shaft. Since the elastic arm has a certain elasticity, during the rotation of the locking assist mechanism, the second protrusion separates from the elastic arm, and at the same time, the first protrusion separates from the groove to achieve unlocking. Continue to rotate the locking assist mechanism clockwise so that the right end 19 of the locking assist mechanism abuts against the socket mounting panel, as Figure 6 shown. Continue to apply a clockwise force to the locking assist mechanism to separate the socket mounting panel from the plug, thereby playing a role in assisting separation. Finally, separate the head and socket.

[0032] The locking mechanism of the present invention has both locking and unlocking assistance functions. When the head and socket are separated, it is necessary to rotate to unlock first and then rotate to assist separation. There is a sequence for unlocking, and the rotation unlocking process must be passed before assisting separation. And since the directions of the forces applied to the locking assist mechanism during unlocking and assisting separation are the same, both clockwise, it can prevent misoperation and avoid the situation in the prior art where the assisting mechanism is damaged easily when the screw is not fully unscrewed and then assisting separation is carried out.

[0033] The present invention can achieve locking with the cooperation of the first protrusion and the groove, and further locking can be achieved with the cooperation of the elastic arm and the second protrusion.

[0034] The above is the description of the present invention in combination with the drawings. Of course, the mechanism of the present invention is not limited to the above description. It can also be to set the locking post on the plug mounting panel and set the locking mechanism at one end of the socket. The principles of locking, unlocking, and assisting separation are the same as those described above.

[0035] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Any person skilled in the art, without departing from the scope of the technical solution of the present invention, any simple modification, equivalent change, and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
