Description

  The present invention relates to an assembly structure of a power table tap, and in particular, an independent switch is provided in each insertion hole of the branch type power table tap, and the structure includes a switch body between two positive and negative electrode bodies. In particular, the present invention relates to an assembly structure of a power table tap, in which a terminal seat body is incorporated, a coupling force between members can be increased by multi-point pressure welding assembly, and a welding operation can be avoided.

  A conventional power strip branch tap is generally connected to the positive and negative connection terminals with an internal electrode plate, and the terminal is directly stretched from the electrode plate, but the material used cannot meet the mechanical physical conditions, Terminals are easy to fall off and cannot be repaired. There is also a method of fixing independent terminals with screws, but this structure is easy to loosen because each terminal is fixed at a single point.

  Recently, depending on the needs of the application, there is an individual control type individual switch installed in each insertion hole, and each switch is individually fixed to the table tap housing with screws, but the production efficiency is low and it is easy to loosen There's a problem. Also, when the terminal to which each belongs is fixed with a screw, it is easy to loosen due to expansion and contraction due to heat in the process of use and vibration of external force. A danger is formed.

  In addition, there is also a connection that uses a welding method for electrical continuity between members, but if the heat generated during use becomes high temperature, the poorly welded part will be lost due to heat melting, which is dangerous. Sometimes. There is also a method of constructing a circuit with electric wires, and the related electrical conduction paths are connected with enameled wires or insulated flexible wires, but first the insulating layer is removed during production processing and soldering work is started. The disadvantage is that the production efficiency is very slow.

Taiwan Patent No. 81295876 supports a switch and an outlet unit with a plurality of electrode pieces, and is assembled by insertion connection between the power wire protector and the electrode piece. Convenient for repair.
Some of the above-mentioned designs have different standards (number of insertion holes), and it is necessary to produce parts with different standards in advance according to changes in the number of insertion holes for each required member. Not only does this increase the burden and cost of inventory components, but it also cannot flexibly meet market needs.
