Description

A current test terminal

technical field

The invention belongs to the field of electrical connection, and in particular relates to a current testing terminal.

Background technique

In the field of electrical connectors, the current test terminal is one of the important components for electrical connection and current test. The existing test terminal mainly has two structures. One is that the conductive part is composed of a whole metal set and a sliding part. The metal kit includes conductive sheets, test sockets and wiring components. This structure can effectively switch the circuit and complete the current test. However, this kind of metal kit requires high processing technology, consumes a lot of copper materials, and has high production costs; another The conductive part is composed of a long conductive piece, a short conductive piece, a sliding part, a test insert, and a wiring part. The test insert is a separate machined part, and the processing cost is high, and the copper consumption is large. When using the contact component, the test insert needs to be It is inconvenient and wasteful to unscrew the cylinder.

Contents of the invention

Aiming at the above-mentioned deficiencies, the present invention provides a current testing terminal, which includes an insulator, a long conductive part and a short conductive part arranged in the insulator, a breaking device for connection or disconnection, and screws and crimps for wiring. wireframe.

The present invention is achieved through such a technical solution: a current test terminal, including an insulating part, the insulating part is composed of two identical plastic parts assembled in front and back, and the long conductive part and the short conductive part arranged in the insulating part Conductive parts, breaking devices for connecting or cutting off the current between long and short conductive parts, screws and crimping frames for wiring. The long and short conductive parts are composed of a conductive piece and a hollow cylinder, and the two are fixedly connected. There is a threaded hole on the conductive piece, and the centerline of the threaded hole coincides with the centerline of the inscribed circle of the hollow cylinder. The threaded hole is used for screwing the screw of the connection assembly, and the connection piece of the connection assembly is electrically connected with the conductive member. The long and short conductive sheets are composed of two layers of copper sheets, and the two layers of copper sheets can be formed by bending 180 degrees or riveted. The hollow cylinder can be circular, hexagonal, or square. A test plug can be inserted into the hollow cylinder for testing. Since the hollow cylinder is composed of two halves, a tight connection should be formed between the two parts, and the connection method can be a dovetail groove type or a hoop type. Since the current test terminal block may be installed with contact components, the insulator is located above the hollow cylinder to reserve a gap, which is convenient for the connection component to pass over the insulator. The crimping frame is used to accommodate the wires and is pressed tightly with screws.

The utility model has unique advantages and beneficial effects as follows:

Because the present invention adopts the integral structure of the conductive sheet and the test insert, the machined test insert is no longer used, which saves materials and reduces the cost. There is no need to unscrew the test insert when using the contact assembly, which saves installation time.
