Problems solved by technology

[0004] One of the disadvantages of the existing RJ45 connector is that it can only be connected to a network cable and cannot be connected to an ordinary cable, and the transmission current is at the milliampere level, which gradually cannot meet the requirements of higher power transmission; the second disadvantage is that the locking method is a male plug. The claw Ⅰ is matched with the slot of the female socket. When unlocking, you need to press down on the short claw Ⅰ, which is inconvenient to operate, and requires a large operating space, and it is inconvenient to maintain the product in a small space.

Embodiment 1

[0042] see Figure 4 , is a schematic diagram of Embodiment 1 of the plug designed in the present invention. The plug 1 includes an insulator 102 , a cover plate 103 covering the insulator for insulation protection, two wire inlets 104 at the rear end of the insulator, and an eight-pin contact inside the insulator. The structures of the insulator, the cover plate, the wire inlet, and the eight-core contact piece and their mutual connection relationship are consistent with those of the existing RJ45 connector plug, and will not be described in detail in this embodiment.

[0043] Please also see Figure 5 , the plug 1 also includes a locking elastic piece 4, a slider, and a force application member. The locking elastic piece 4 is rotatably mounted on the insulator 102 through a rotating shaft 5, and its front end has a protruding lock 401, the lock 401 cooperates with the card slot 201 in the socket 2 to lock the plug and socket when mating. The lock 401 extends downwards to f...

Embodiment 2

[0050] see Figure 6 and Figure 7 , is a schematic diagram of the second embodiment of the plug designed in the present invention. The plug includes insulators, cover plates, wire inlets, locking springs, pins, pull rings, pressure springs, buttons and other components. The connection relationship of each component is the same as that in Embodiment 1 and will not be repeated. The difference is that the front end of the locking shrapnel 4 extends downwards to form a claw II 403, which is located in front of the buckle 401, and its end abuts on the insulator 102, and the claw II 403 is formed on the plug and The guide part 402 plays a guiding role when the socket is mated. At the same time, the width of the claw II should be narrower than that of the locking shrapnel, so that it has enough elastic force for the automatic return of the locking shrapnel and the pull ring.

Embodiment 3

[0052] On the basis of Embodiment 1 or Embodiment 2, the present invention designs a new type of quick connection on-site wire connector, which consists of the plug 1 described in Embodiment 1 or Embodiment 2 and the female socket 2 of the existing RJ45 connector plug-in components.

[0053] When the plug and socket are connected, insert the plug 1 into the socket 2, the buckle 401 of the locking shrapnel 4 is deformed and flattened, and the elastic claw II 403 is deformed under pressure. After the plug 1 is inserted into the socket 2, the elastic force of the elastic claw II 403 locks the shrapnel The locking buckle 401 springs into the card slot 102 to realize the locking of the plug and the socket.

[0054] When the plug socket is unlocked, pull the pull ring 14 backwards. Since the pull ring is made of flexible material, and by virtue of the cooperation between the transition part 143 and the inclined surface 1033, when the connecting part 141 slides backward along the gui...

Abstract

Disclosed is a plug; the plug comprises a force application part, a slide block, a lock catch and a locking elastic piece, wherein the slide block is slidably mounted in an insulator and is connectedwith the force application part; the lock catch is mounted on the insulator in a rotationally connected mode, and is matched with a clamping groove in a socket for locking the plug and the socket; thelocking elastic piece is connected with the slide block and can rotate to enable the lock catch to be separated from the clamping groove to unlock the plug and the socket when the slide block moves;the locking elastic piece extends downwards to form an elastic claw II which abuts against the insulator and is used for performing automatic reset of the locking elastic piece, the slide block and the force application piece after unlocking is completed. When the connector adopting the plug is used for unlocking the plug and the socket, only the force application part needs to be pulled, the locking elastic piece is pushed by the slide block to rotate to enable the lock catch to be separated from the clamping groove, so that the operation is convenient; and in addition, the plug can be quickly inserted and plugged in the small space, and the product is convenient to maintain.

Description

technical field [0001] The invention belongs to the technical field of connectors, and in particular relates to a plug and a novel quick-connect on-site wire connector using the plug. Background technique [0002] As a common Ethernet interface, the RJ45 interface is widely used. In the design of the power supply system, sometimes the RJ45 interface is needed to transmit high power. At this time, the tail of the plug should be connected with a two-core cable, and it should meet the requirements of on-site wiring and cable detachability. At the same time, the plug should have a reliable locking structure when mated with the socket, and can be unlocked in a simple manner. [0003] see Figure 1 to Figure 3 , the existing RJ45 connector usually uses the claw I 101 at the end of the male plug 1 to cooperate with the locking groove 201 in the female socket 2 to achieve locking. The material of the plug 1 is elastic plastic, and the claw Ⅰ101 can be deformed within a certain ran...
