Detailed Description

The present application is described in further detail below in conjunction with fig. 1-4.

Example 1:

the embodiment of the application discloses an electric connection plug.

Referring to fig. 2 and 3, the electrical connection plug includes: the plug comprises a shell 1, a plug inner core 2 and a poking piece 3, wherein the plug inner core 2 is a combined structure of an insulating seat and a plurality of conductive posts, the plug inner core 2 is installed in the shell 1 and used for realizing the function of a plug, and a connecting cable of the plug inner core extends out of the shell so as to be connected with corresponding equipment.

In order to fix the plug and the adaptive connecting socket to each other, the two ends of the shell 1 are provided with rotating shafts 4 at the side parts, the rotating shafts 4 are connected with a buckling structure 5, the buckling structure 5 can be formed by interconnecting two C-shaped side plates through a handle, and the C-shaped side plates are positioned at the side parts of the shell 1 and one end of each C-shaped side plate can be connected with the rotating shaft 4; the fastening structure 5 can be turned relative to the housing 1 to fasten the positioning posts of the side of the adapted connection socket. The pulling sheet is arranged on the handle of the fastening structure 5, so that the worker can conveniently pull the fastening structure 5.

In order to reduce the electric shock hazard, the plug is provided with the following steps:

referring to fig. 3, the rotating shaft 4 includes an intermediate shaft 41 and a sleeve 42, wherein the sleeve 42 is formed on the outer wall of the housing 1, the intermediate shaft 41 is located inside the sleeve 42 and is attached to each other, and the intermediate shaft 41 penetrates through the housing 1 inwards to be in rotational connection with the housing 1. One end of the C-shaped side plate of the fastening structure 5 is fixed to the outer end of the intermediate shaft 41.

One benefit of the above arrangement is that: the tightness of the shell 1 is ensured, and the outer wall of the shell 1 is prevented from being condensed by water vapor in a humid environment and penetrating into the plug along the hole required by the sliding and rotation of the outer wall; at the same time, the opening and casting of the housing 1 is relatively easy.

The intermediate shaft 41 is connected with a linkage on-off mechanism which is arranged between the shell and the plug inner core 2 and comprises a buckling detector 6, a control module 7 and a switching device 8.

Referring to fig. 3 and 4, the fastening detector 6 is coupled to the intermediate shaft 41, and the fastening detector 6 is electrically connected to the control module 7, for detecting whether the fastening structure is disconnected from the connection socket, and outputting a detection signal value to the control module 7; the switching device 8 is used for switching on and switching off the cable connecting end of the plug inner core 2, and the control module 7 is electrically connected to the switching device 8 and used for controlling the switching action of the switching device 8 according to the detection signal.

It should be noted that the linkage power on-off mechanism is set to take power from the cable connected with the plug inner core 2, and the power taking mode is to connect a current limiting resistor in series, or correspondingly set a transformer circuit formed by combining a transformer, a rectifier bridge, a filter circuit and the like when the requirement of transformation exists, so as to take power.

Firstly, because the linkage on-off mechanism takes electricity from the cable connected with the plug inner core 2, the plug cannot have response influence when the buckling structure 5 rotates during non-live working, and can be considered to be always in a set fixed state; only when this plug live working, there is the electric shock risk and only will respond, whether disconnect and cable's connection is decided according to whether buckle structure 5 and socket disconnect each other moreover, so this plug reducible facility does not operate the electric shock risk of plug when in time cutting off the power supply.

In this embodiment, the buckling detector 6 may be a potentiometer, and a rotating shaft (knob shaft) of the potentiometer is fixed to one end of the intermediate shaft 41 penetrating into the housing 1. When the buckling structure 5 drives the intermediate shaft 41 to rotate, the resistance of the potentiometer changes. Under the setting, whether the buckling structure 5 is disconnected from the socket or not can be designed according to the corresponding resistance range of the potentiometer, and the output range of the potentiometer during buckling can be verified and set as a threshold range because of the resistance change and the voltage change; when the potentiometer is used, the potentiometer output exceeds the threshold range, and the control module 7 determines that the buckling structure 5 is disconnected from the socket, and the switching device 8 is needed to be powered off. The control module 7 is a circuit board integrated with a microprocessor.

Referring to fig. 5, the switching device 8 includes a terminal 81, an intermediate conductive member, and an electromagnetic generating unit 83.

The terminals 81 are of a cuboid structure, the number of the terminals is two, and the two terminals 81 are symmetrically distributed in the shell 1 and are fixed with the shell 1 in an adhesive manner; the terminal 81 is hollow, one side of the inner cavities of the two terminals 81, which are away from each other, is in an opening structure, and one side of the inner cavities is used for allowing a connecting wire of the plug inner core 2 to stretch in for wire harness treatment, namely, the inner cavities are used for connecting the plug inner core 2; another cable for connecting the plug to an external device is inserted.

The middle conductive member is located in the extending direction of the separation region of the two terminals 81 and is kept electrically separated from the terminals 81 by a predetermined restoring force.

An electromagnetic generating unit 83 such as: an electromagnet; which is disposed laterally of the terminal 81 and is opposite to the intermediate conductive member; the electromagnetic generating unit 83 is electrically connected to the control module 7.

When the electric signal output by the potentiometer accords with the buckling structure 5 and buckles the matched connecting socket, the electromagnet is started, and the middle conductive component is magnetically attracted to move and electrically contact with the two terminals 81.

Similarly, when the fastening structure 5 is disconnected from the connection socket, i.e. opened, the electromagnet is not operated, and the intermediate conductive assembly is retracted to the original position under a preset restoring force to be electrically separated from the terminal 81.

From the above, it can be seen that:

when the plug is electrified, as long as the buckling structure 5 is opened, the control module 7 controls the switch device 8 to disconnect the plug inner core 2 from an external cable, so that the exposed contact pin is not electrified any more, and the electric shock risk is reduced;

moreover, when the control module 7 burns out, or the electromagnetic generating unit 83 burns out, the plug can be disconnected from the cable, so that the safety is relatively high, and the hidden danger caused by the failure of the linkage power-on and power-off mechanism can be basically avoided.

Referring to fig. 5, the intermediate conductive assembly includes a U-shaped plate 821, a fin 822, and a spring 823.

Wherein the U-shaped plate 821 extends between the two terminals 81 with its opening facing away from the separation of the two terminals 81. A conductive block 811 is fixed to a surface of the terminal 81 facing the side wall of the U-shaped plate, and the conductive block 811 is connected to the cable or the pin of the plug core 2 with a wire.

The two fin plates 822 are respectively fixed at two end edges of the opening of the U-shaped plate, and the two fin plates 822 extend towards the direction away from each other. One end of the spring 823 is fixed to the fin 822, and the other end is fixed to the side wall of the terminal 81. The U-shaped plate 821 is separated from the above-mentioned conductive block 811 by the spring 823, thereby disconnecting the two terminals 81, i.e., disconnecting the plug core 2 and the cable to the outside.

Referring to fig. 5, the above-mentioned conductive blocks 811 are provided in plural, two for example, on each terminal 81; the two conductive blocks 811 are slidably arranged along the movement of the U-shaped plate 821.

The pins of the plug core 2 are divided into two groups of 6, and the pins of the same group are connected to the same conductive block 811. The cable sides are similarly grouped so as the U-shaped plate 821 slides gradually between the two terminals 81, the plug is first a 6-core plug, and then becomes a 12-core plug.

According to the above, the plug can be used for changing the actual effective core number, and the plug with multiple core numbers can be realized.

Referring to fig. 5, to achieve the above, an effective core number adjuster 9 is provided for urging the U-shaped plate 821 into sequential contact with each of the conductive blocks 811.

The effective core number adjuster 9 includes a micro motor 91 and a pushing shaft 92, wherein the micro motor 91 is electrically connected to the control module 7 and fixed to the inner wall of the housing 1; the output shaft of the micro motor 91 is fixed with a threaded tube 93, and the threaded tube 93 may be an internally threaded tube. One end of the pushing shaft 92 is externally threaded and is screwed to the threaded pipe 93.

A limiting rod 94 is vertically fixed on the outer wall of the pushing shaft 92, and one end of the limiting rod 94 far away from the pushing shaft 92 is connected in a sliding groove preset on the inner wall of the shell 1 in a sliding way; the slip direction of the restriction lever 94 is parallel to the length direction of the pushing shaft 92.

When in use, the utility model is characterized in that: the micro motor 91 rotates the threaded pipe 93, and the restriction lever 94 prevents the pushing shaft 92 from rotating, so that the pushing shaft 92 moves linearly.

The electromagnetic generating unit 83 is fixed to a pushing shaft 92, and the pushing shaft 92 extends toward between the two terminals 81. An insulating rod 831 is fixed to a side of the electromagnetic generating unit 83 facing the terminals 81, and the insulating rod 831 extends between the two terminals 81.

When the electromagnetic generating unit 83 is turned on, the magnetic U-shaped plate 821 is abutted against the insulating rod 831.

According to the above arrangement, the effective core number of the plug can be changed by adjusting the position of the electromagnetic generating unit 83, that is, the position of the insulating rod 831.

In one embodiment, the control module 7 is electrically connected to a wireless transmission unit 71, and the wireless transmission unit 71 may be a bluetooth module.

According to the above arrangement, a worker can connect a plug through a mobile phone or the like to control the micro motor 91 or manually control the linkage power-off mechanism.
