Description

Button structure of terminal connector

Technical field

The utility model relates to the technical field of connection terminals, in particular to a button structure of a connection terminal connector.

Background technique

As a connecting component of electronic components, electrical appliances, etc., the terminal can play the effect of wiring and energization, and realize the good connection function of the wiring energization. It is an important wiring component for electrical connection and connection between the terminal and the terminal. Some existing wiring terminals adopt buttons and metal parts to realize the functions of one-step wiring and one-step disconnection, which facilitates wiring and disconnection. Generally, the housing and button of this type of terminal are insulating parts, and the metal parts are the wiring parts that conduct the wires and are placed in the housing. The bottom of the metal parts is fixedly installed on the housing and will not move. The top of the metal parts is generally set There is an elastic metal sheet and a fixed sheet tightened by the elastic metal sheet. One part of the button needs to be inserted into the shell, and the other part is placed outside the shell. By applying force to the button, the elastic metal sheet is pressed down to form the elastic metal sheet and formed on the fixed sheet After a certain gap, the wire is inserted into the shell and is in the gap, the button is reset, and the elastic metal sheet is reset and clamps the wire to form a stable connection on the fixed sheet. When disconnecting, you can also use the lift button to easily disconnect. However, the existing button structure has some shortcomings, as follows: (1) The pressing part of the button is far away from the elastic metal sheet, and the button needs to be lifted for a long distance to push down the elastic metal sheet and the button is fully lifted. Failed to form the maximum pressing opening angle of the elastic metal sheet; (2) According to the principle of mechanics, it is necessary to facilitate the lifting of the button. The pivot point is the pivot point. The longer the hand force point of the button can save effort, but the longer the button This causes the overall aesthetics to be insufficient; (3) The buttons are mostly straight or pressed slightly downwards, which increases the force of the button and costs when the button is lifted; (4) The pivot point of the button rotation is relative to the shell rotation. The pivot point cannot be rotated, moved or slid, which cannot effectively reduce the length of the pressing end; (5) The push-up force surface of the button is mostly a smooth surface, which is easy to cause the sliding hand to lift or the button cannot be lifted together, and the friction is insufficient .

Utility model content

The utility model aims to overcome the defects of the prior art, and aims to provide a button structure of a terminal connector. The button structure of the terminal connector adopts an integrated structure, which is strong and durable, and the pressing ends are branched to form two pressing pieces , It can make the pressing force stable, and at the same time, the pressing head is designed to rotate and slide along the chute inside the shell when it rotates, which can reduce the rotation distance, and the button can be lifted to achieve the effect of wiring. It also saves pressing force, is convenient and quick, and has a clever structure; most of the button handles of the buttons are placed below or flat on the top surface of the shell, only the top position of the small button handles protrudes, and the shape remains basically square The structure improves the aesthetics.

The technical solution adopted by the utility model to solve its technical problem is: a button structure of a terminal connector, including an integrated button housing, the button housing is composed of a horizontally or upwardly inclined button handle and a downwardly inclined button The button handle and the pressing part form an obtuse angle. The pressing part is composed of two pressing plates whose branches are symmetrical. The top surface of the pressing plate is a downwardly inclined surface, and the back of the pressing plate is formed with the top surface The downwardly inclined surface in the same direction, the top surface and the back surface of the pressing plate are inclined upwardly. The arc pressing part formed between the top surface and the bottom surface of the pressing plate is formed as an angled arc pressing part. A circular arc head with a convex arc; the inner surface of the pressing plate corresponds to the position of the arc pressing part, and there is a pressing head that corresponds to the specifications of the arc pressing part to form a pressing action. The upper part of the pressing head is convex It is clamped into the sliding groove of the terminal connector housing and forms the entire button structure when the pressing head presses the rotating head of the metal part in the terminal connector.

Further, the bottom of the button handle is provided with anti-slip patterns that increase friction when lifting the button housing with a human hand.

Further, the hand end of the pressing handle is inclined upward and forms an angle with the position of the bottom anti-slip pattern.

Further, one end of the rotating head facing the pressing head is a right angle end, and the other end is an arc end connected to the right angle end to form a loop structure, and a chamfer is formed between the right angle end and the pressing head.

To sum up, the button structure of the terminal connector of the present invention adopts an integrated structure, which is strong and durable. The pressing end part is branched to form two pressing pieces, which can make the pressing force stable, and the pressing head is designed to rotate in the housing. And when rotating, sliding along the chute inside the shell can reduce the rotation distance, so that the button can be lifted a little to achieve the effect of wiring, and it also saves pressing force, convenient and fast, and ingenious in structure; the button has a large button handle Part of the positions are placed below or flat on the top surface of the shell, only the top position of the small button handle is protruding, and the shape maintains a basic square structure, which improves the aesthetics.
