Description

Technical Field

[0001] This utility model relates to the field of electrical engineering, and more particularly to electrical connection devices, especially an improved experimental connector. Background Technology

[0002] Electrical connectors are widely used in circuit connections, and disconnecting connectors, in particular, facilitate circuit disconnection. In the prior art, patent document (CN223502331U) describes a closed-type disconnecting connector. This connector achieves circuit connection / disconnection by sliding a disconnecting slider left and right. However, this connector has some drawbacks in practical use. First, the upper and lower guide blocks are connected by screws, and the lower guide block can accidentally detach from the screws, easily causing the product's connection function to fail. Second, when the disconnecting slider moves to the right side, if the screws are not tightened, they can easily detach from the gap between the two conductors when the cover is opened, causing the entire disconnecting slider to fall off, affecting normal use and testing.

The insulating component is provided with a left limiting rib and a right limiting rib. The left limiting rib is located below the lower guide block and to the left of the lower end of the screw. The right limiting rib includes a first right rib and a second right rib. The first right rib is located below the lower guide block and to the right of the lower end of the screw. The right end of the second right rib is vertically connected to the left side of the front end of the first right rib. The second right rib is located below the lower guide block, in front of the lower end of the screw, and below the gap. An insulating cap is fixedly connected to the upper side of the second upper guide block. The left and right sides of the insulating cap are respectively provided with a first mark and a second mark. The left and right sides of the upper surface of the insulating component are respectively provided with a first mark observation window and a second mark observation window.

[0005] Preferably, the anti-detachment structure is a riveting structure.

[0006] Preferably, the first and second wire clamping frames are respectively provided with wire clamping bolts, and the insulating component is provided with test holes above the first and second conductors.

[0007] Compared with existing technologies, the advantages of this invention are positive and significant.

It offers versatile wiring options, capable of connecting single-strand solid wires and multi-strand wires, and also allows for crimping of terminals.

[0019] 2. This utility model achieves circuit switching by sliding the slider left and right.
