Problems solved by technology

Compared with the patent document CN101540455A, the locking device disclosed in this patent document is more convenient to operate, but these two locking devices are arranged on the outside of the housing, and are easy to fall off or be damaged by touching other objects during use , and because the female end of the socket is always connected to the power supply, the plug is live during the plugging and unplugging process. After the male end of the plug is pulled out, the live terminal in the socket female end of the socket is exposed, which is likely to cause electric shock accidents, so it has a large Security risks

Embodiment 1

[0038] see figure 1 , a power connector with a locking device, including a housing 1, the housing 1 includes an upper housing 12 and a lower housing 13, the housing 1 is provided with a combination switch 2 for turning on or breaking a circuit, The combination switch 2 is fixedly arranged inside the lower casing 13, the input terminal of the combination switch 2 is connected to the power supply, and the knob 21 arranged at the knob installation port 14 above the upper casing 12 controls the combination switch 2 through an operating rod 22. On and off of the switch 2; the power connector of the present invention also includes a socket 3 and a plug 4 matched with the socket 3, and the socket 3 extends into the casing through the socket 11 provided on the casing 1 1 inside; the connection terminal of the socket 3 is electrically connected to the output terminal of the combination switch 2; the plug 4 is provided with a bump 41; A locking device that cooperates with the protrusio...

Embodiment 2

[0045] In order to prevent the combination switch 2 from being turned on due to misoperation before the plug 4 is inserted into the socket 3, thereby causing the live parts of the socket 3 to be exposed and causing electric shock accidents, on the basis of the first embodiment above, the housing 1 There is a positioning device for positioning the limit frame 5 inside. After the limit frame 5 is positioned, the combination switch 2 can only be in the off position, but cannot be rotated to the on position.

[0046] see Figure 8 , the positioning device in this embodiment includes a locking block 7, one end of the locking block 7 is provided with a rotating shaft 72, and a torsion spring 73 is arranged on the rotating shaft 72, and the locking block 7 is hinged on the On the support 9; the other end of the lock block 7 is provided with a block 71, the limit frame 5 is provided with a draw groove 50 that cooperates with the block 71, and the support 9 is provided with a block for...

Embodiment 3

[0051] Since the working environment of the industrial power connector is relatively poor, there are many dusts, muddy water, etc., in order to prevent the socket 31 of the socket 3 from being blocked or corroded, on the basis of the above-mentioned embodiment 1 or implementation 2, the housing 1 Outer side is positioned at the socket 31 place of described socket 3 and is hinged with socket cover 8, see Figure 11 , the hinge shaft of the socket cover 8 is arranged above the socket 31 .

[0052] In this embodiment, the socket cover 8 is provided with a locking part 81 on the inner cover surface of the side away from the hinge axis, and the corresponding position of the plug 4 is provided with a limiting convex part 42, and the plug 4 is inserted into the Behind the socket 3 , the locking portion 81 cooperates with the limiting convex portion 42 to realize the limiting connection between the socket cover 8 and the plug 4 .

Abstract

The invention discloses a power supply connector with a locking device. The power supply connector comprises a casing body, a socket and a plug. A combination switch which switches on or off a circuit is arranged in the casing body. On and off of the combination switch are controlled by a knob which is arranged above the casing body. The socket stretches into the casing body. A wiring terminal of the socket is electrically connected with an output terminal of the combination switch. A convex block is arranged on an insertion part of the plug. The locking device which matches the convex block and locks or unlocks the plug and the socket is arranged on the inner side of the casing body and between the socket and the combination switch. According to the power supply connector provided by the invention, after the plug is inserted into the socket, the knob of the combination switch can be operated to power the plug and the socket; and when power supply is carried out, the plug cannot be pulled out, and the casing body cannot be disassembled and separately operated, thus potential safety hazards caused by misoperation in a charged state are avoided.

Description

technical field [0001] The invention relates to the technical field of electrical connection, in particular to a power connector with a locking device. Background technique [0002] The current of industrial electricity is generally much larger than that of civilian electricity, and the use environment of electrical appliances and switches in industrial circuits is relatively harsh, which has greater safety hazards than civilian circuits. Therefore, the industry's requirements for industrial switches higher to prevent electric shock accidents. [0003] In order to facilitate the power supply of electric tools or other electrical appliances, it is often necessary to frequently move the wires connected with plugs and sockets. During the movement, it is easy to separate the plug from the socket due to excessive pulling or touching other objects. The current is generally very large, and it is easy to generate an arc at the moment when the plug is separated from the socket. It ...
