In order to solve above-mentioned technical problem, the utility model proposes techniques below scheme: a kind of can short circuit flexibly and easily Three layers of terminal, including housing and metal in flakes, the metal of three layers of different length is stuck on the corresponding position of housing in flakes, shell Be DIN guide rail buckle bottom body, DIN guide rail buckle left end have dismounting plectrum, housing upper end and left and right sides have multiple mark buckle, Wire connection hole and a word play insertion hole, have the short circuit sheet targeting port of multiple eight words depressions, housing along axis, housing front Upper end is provided with short circuit sheet insert port, and there is the groove that difformity caves in housing front.

Described metal two ends in flakes have the spring leaf of crimping lead wire, short circuit sheet connecting hole to be positioned at metal and go up in flakes, spring leaf Upper end is machined with conductor compression jointing mouth.

Described housing uses PP, PC plastic insulation material, and uses integral forming process to make.

Described spring leaf is made for elastic and the preferable metal material of electric conductivity, by described conductor compression jointing mouth by wire jail Admittedly be crimped on metal and go up in flakes, described metal metal material for conducting electricity very well in flakes is made, the hole of short circuit sheet connecting hole Footpath pluggable short circuit sheet, aligns with short circuit sheet targeting port centrage in the position of short circuit sheet connecting hole.

Described DIN guide rail buckle is fixed on DIN guide rail, is capable of tearing open of whole device by stirring dismounting plectrum Unload.

Described wire connection hole is circular port, and wire can be connected in conductor compression jointing mouth through wire connection hole.

It is square opening that a described word plays insertion hole, it is possible to the word inserting a certain size rises, and a word of insertion rises can be dialled Dynamic compression spring leaf.

The center of described short circuit sheet insert port and three-layer metal short circuit sheet connecting hole in flakes on the same line, short circuit sheet Short circuit sheet insert port and three-layer metal short circuit sheet connecting hole in flakes can be passed.

This utility model has the advantages that:

1, increase the short circuit function of three layers of terminal, expand its scope of application.

2, by using the short circuit sheet of different model to realize three layers of any one layer of terminal block short circuit, any two-layer of short circuit and three The function of the full short circuit of layer, improves the motility of three layers of terminal short circuit.

3, have only to plug a short circuit sheet and achieve that three layers of any one layer of terminal block short circuit, any two-layer of short circuit and three The function of the full short circuit of layer, improves three layers of terminal block of short circuit or cancels the work efficiency of three layers of terminal block of short circuit.

4, former wiring will not be touched during plug short circuit sheet, it is to avoid when three layers of terminal block of short circuit or cancellation three layers of terminal block of short circuit Cause the risk that loose contact between terminal and wire is even broken.

5, because of the expansion of its scope of application, the installing space of whole equipment or system can be reduced to a certain extent.
