Detailed Description

The utility model is further described below with reference to the accompanying drawings:

referring to fig. 1-3: the dual-purpose binding post in this embodiment, including casing 1 and electrically conductive piece 2, be equipped with two at least wiring units on the casing 1, two wiring units all with electrically conductive piece 2 electric connection, wiring unit includes wiring room 3, line ball piece 4, spring 5 and depression bar 6, wiring room 3 is located inside casing 1, the tip of electrically conductive piece 2 of bottom fixed mounting of wiring room 3, be connected with top wiring hole 7 and lateral part wiring hole 8 on the wiring room 3, depression bar 6, spring 5 and line ball piece 4 from the top down install in proper order on top wiring hole 7, the upper and lower both ends of spring 5 are fixed connection depression bar 6 and line ball piece 4 respectively, be equipped with first wiring hole 9 and the second wiring hole 10 of upper and lower intercommunication on depression bar 6 and the line ball piece 4 respectively, be equipped with detachable fixed connection structure between the upper end of depression bar 6 and the casing 1.

Working principle: the wire is connected with the wiring unit, and the conduction of the circuit is realized through the conducting piece 2. When the electric cabinet is used, the detachable fixed connection structure is detached firstly, so that the compression bar 6 and the shell 1 can move, then the compression bar 6 is pulled upwards, the compression bar 6 brings up the compression bar 4 through the spring 5, the compression bar 4 and the conductive piece 2 generate a gap, and the first wiring mode is to enable a lead to enter from the lateral wiring hole 8, so that the electric cabinet is suitable for wiring of a left circuit and a right circuit, for example, wiring between two electric cabinets is realized. The wire is placed between the line ball piece 4 and the electrically conductive piece 2, then pushes down depression bar 6, makes spring 5 compress, and the elasticity is used in line ball piece 4, makes the wire centre gripping between line ball piece and electrically conductive piece, is difficult for taking place to damage the wire and the poor problem of contact.
