Description

Technical Field

[0001] The utility model relates to the field of terminal production, in particular to a snap-on type terminal. Background Art

[0002] A terminal block is an accessory product used to achieve electrical connection, and is classified as a connector in the industry. Currently, when two wires are connected, a terminal block is often used. The terminal block mainly includes an insulating shell and an internal conductor. A screwdriver or other tool is required to rotate the screw inside the terminal to tighten the wire. The operation is relatively cumbersome, and the purpose of one-time and quick wiring cannot be achieved. In addition, since the wire cannot completely contact the conductor, there is a problem of poor conductivity. Utility Model Content

[0003] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0004] A snap-fit ​​terminal comprises an insulating outer shell, a conductive block is arranged at the bottom of the inner surface of the insulating outer shell, the top cross section of the conductive block is triangular, an embedded card hole is opened at the top of the insulating outer shell at a symmetrical position in the middle of the conductive block, a T-shaped pressure rod is clamped in the embedded card hole, and both sides of the T-shaped pressure rod are fixedly connected with card strips used in conjunction with the embedded card hole;

[0005] The bottom of the T-shaped pressure rod is an inclined surface adapted to the top of the conductive block. The bottom of the T-shaped pressure rod is rotatably connected to a pressure plate. One end of the exposed metal wires of the two conductors are respectively inserted between the conductive block and the pressure plate, and then the T-shaped pressure rod is pressed to make the clamping strip engage with the embedded clamping hole. At this time, the pressure plate squeezes the conductor to fully contact with the conductive block, thereby improving the conductive efficiency. The operation is simple and the manufacturing cost is low.

[0006] Furthermore, a protrusion is fixedly connected to one side of the pressure plate close to the conductive block, and a groove matching the protrusion is provided at the top of the conductive block, thereby improving the tightness of the pressing and effectively preventing slipping.

[0007] Furthermore, an anti-slip block is fixedly connected to the bottom of the inner surface of the insulating shell at both sides of the conductive block, and an anti-slip thorn is arranged on the top of the anti-slip block. The pressure plate is arranged to extend to the position above the anti-slip thorn to improve the anti-slip effect.

[0008] Working principle and beneficial effects: By inserting one end of the exposed metal wires of the two conductors between the conductive block and the pressure plate, and then pressing the T-shaped pressure rod to make the clamping strip engage with the embedded clamping hole, the pressure plate squeezes the wires to fully contact the conductive block, thereby improving the conductive efficiency, and the operation is simple and the manufacturing cost is low.
