Description

Terminal block for LED

technical field

The utility model relates to a connection terminal used for LED connection, in particular to a connection terminal structure which adopts plug-in connection to realize simple one-time connection or one-time off-line during LED connection.

Background technique

Existing LED wiring generally uses wires and terminals or connectors to be fixedly connected by nuts, screws, rivets, etc., or connected by welding. In recent years, plug-in connectors for LEDs have also appeared. The method is specifically that one or more strands of wires are connected to the plug, and another strand or more strands of wires are connected to the socket, and then the wiring is formed by plugging the plug and the socket. In this way, the structures of the existing connecting terminals continue to show various changes, and the structures of the connecting terminals are also different, as well as the degree of complexity and the way of connecting them. Although the structures of each terminal block are different, the biggest disadvantage of the existing terminal blocks is that the wiring cannot be completed in one step, and multiple steps of operation or wiring are often required to complete the wiring work, and the wiring is complicated. Especially for those shells that need to be opened, use connectors or fixings, such as bolts, rivets, etc. to connect the metal end of the wire to the metal conductor in the terminal, and then close the connector terminal to realize the wire connection. On the device, the wiring of this kind of structure is complicated, and the case needs to be opened again when it is off-line, and it is extremely inconvenient to go off-line.

Although, some people have invented a terminal block that can be used for one-time connection. However, due to the complex structure of this type of terminal block, the connection effect is not ideal, and the service life is not long, it cannot meet the current diversified wiring requirements. The applicant has been devoting himself to the research and development of a connection terminal that can be used in the field of LED connection and has a simple structure.

Contents of the invention

The terminal block is mainly composed of two parts, the shell and the conductive metal insert. The mating structure can realize one-step wiring or one-step off-wiring of terminal block connectors. When wiring, press the button, the button is pressed and the roll is pressed down, and the pressing of the roll also drives the pressing of the elastic card. At this time, the gap between the elastic card and the top of the frame-shaped main frame increases. , insert the wire with the bare metal end exposed in advance from the wire socket, penetrate into the frame and snap it into the gap between the elastic card and the top of the frame main frame, release the press, at this time, the elastic card and the pressing roll Return due to the elastic restoring force, that is, the elastic card clamps the wire between the elastic card and the top of the frame-shaped main frame to complete the wiring, and since the top of the elastic card is provided with a certain inclined opening, if the wire is connected after wiring When forcibly pulled out, the bare metal end of the wire will be stuck, making it difficult to pull out the wire, which ensures the stability of the wire connection and wiring. Similarly, when off-line, the wire can be easily off-line by pressing the button. The elastic cards are basically hidden in the frame-shaped main frame, in order to realize the cooperation between the elastic card and the frame-shaped main frame to form a mutual force that can clamp the wires, and the pressing of the rolling piece to protrude out of the gap is also to realize the buttons. The pressing function is the same as pressing the roll film, realizing the pressing down of the press roll film, and realizing the simple operation of wiring and off-line.

The concave position and the raised position adopt an angled structure. When the angle between the concave position cooperates with the elastic card, the wire is clamped more firmly, just like a needle inserted into the metal end of the wire, so that the wire is less likely to be disconnected.

Further, all or half of the rolling opening on the top of the pressing roll protrudes from the notch.

The housing is provided with a single wire socket or two wire sockets or three wire sockets, corresponding to the setting of the number of wire sockets in the housing, a single conductive metal insert or two conductive metal inserts or three conductive metal inserts and a single button are provided accordingly Or two buttons or three buttons.
