Description

Press ejection type high-current plug connector

Technical Field

The invention relates to the technical field of plug connector, in particular to a push-out type high-current plug connector.

Background

The existing power circuit designs for household and industrial use mostly adopt the form of plug and socket to connect the equipment and power supply, and various plugs and sockets are different only in the aspects of the matching design of the plug and the socket, etc.

At present, most of plugs in the market are conductive pins or pole pieces which extend outwards and are embedded into preset jacks on a socket, and the combination force of the conductive pins or the pole pieces determines the quality of circuit connection. If the plug and the socket are connected too loosely, the plug and the socket are easy to fall off and power off. Therefore, the existing device plugs and sockets are all configured to be tightly connected. This makes it difficult to pull the plug out of the socket. However, for a device that needs to be moved frequently, the plug is frequently inserted and removed. In addition, when the equipment does not work, the plug is usually required to be unplugged for saving electricity and ensuring the safety of the equipment. Therefore, the plug and the socket are often inserted too tightly, the plug can be pulled out only by applying a large external force by people, and even the plug and the socket can be separated only by pinching the plug and the socket with two hands. Therefore, the electric shock protector is time-consuming, labor-consuming, inconvenient to use and has electric shock risks. If the socket is fixed, such as in a corner or wall, the actual plugging operation is more difficult.

Therefore, it is urgently needed that related manufacturers research and develop an easy-to-plug, which is named as an easy-to-plug in chinese patent publication No. CN2669415, and the application discloses an easy-to-plug, which comprises a movable handle, a shift lever and an automatic reset device. By utilizing the lever principle, the shifting lever is manually stirred to drive the movable handle to move, so that the plug is ejected out of the socket. The novel plug has the disadvantages that the deflector rod is arranged outside the plug, so that the normal use of the plug is influenced, the use space of the plug is limited, and the practical use is inconvenient; the movable handle surrounds the plug, the plug and the socket are abraded after long-term use, the service life of the plug and the socket is influenced, the stress is completely applied to the movable handle and the deflector rod, the requirement on the physical strength of the movable handle and the deflector rod is high, and the joint is easy to break; the stroke of the movable handle is short, and the complete separation of the plug and the socket cannot be realized.

The invention provides a push-out type large-current plug connector, which utilizes the lever principle to design a push-out structure, can realize easy plug and pull of a plug and a socket, and can prolong the service life of the plug and the socket.

The reset spring 2 is sleeved at one end of the support 3 close to the button 1, the button 1 is in contact with the reset spring 2, and after the plug 9 is pulled out of the socket 11, the button 1 moves upwards to reset due to the elastic action of the reset spring 2. The rotating shaft 4 is arranged at the lower end of the support 3 in a penetrating mode, the support 3 is erected on the plug shell 8, and the support is positioned and clamped through the plug shell 8. The V-shaped ejector block is provided with a round hole in a cross arm at one end and sleeved on the rotating shaft 4, the V-shaped ejector block is provided with a round hole in a cross arm abutting connection with one end of the round hole on the support 3, the protruding part of the cross arm at the other end of the V-shaped ejector block abuts against the plug shell 8, the middle part of the V-shaped ejector block is bent and abuts against the socket shell 12, and the included angle of the cross arms at two ends of the V-shaped ejector block is larger than 90 degrees. When the plug 9 is completely inserted into the socket 11, a certain gap is reserved between the V-shaped top block and the socket shell 12, so that the influence of the V-shaped top block on the normal work of the plug 9 when the plug is inserted into the socket 15 is avoided.

When the plug 9 and the socket 11 are in a connected state and need to be pulled out, the button 1 is pressed, the reset spring 2 is compressed, the support 3 is forced to move downwards to drive the V-shaped ejector block to move, the V-shaped ejector block performs swing arm motion around the rotating shaft 4, a cross arm of the V-shaped ejector block abutting against the plug shell 8 portion is tilted upwards, a middle bent portion of the V-shaped ejector block abuts against the socket shell 12 to serve as a support of acting force, and the plug 9 is ejected out of the socket 11. After the plug 9 is separated from the socket 11, the pressing force is removed, the button 1 moves upwards to reset due to the elastic force action of the reset spring 2, and the cross arm of the part, which is abutted to the plug shell 8, of the V-shaped top block falls down due to the self gravity action of the V-shaped top block, and the V-shaped top block returns to the initial position.
