3. terminal cross section commonly used is to be flat, singly is not that to insert pedestal be not very easy, inserts the back because the flat structure is subject to rock in square slot, is that terminal commonly used is difficult for the shortcoming noted for the people, but is adding the generation that causes defective products man-hour all easily.

At above-mentioned defective, the inventor is with its rich experience, several times repeatedly exploitation and experiment, and do painstaking research and design through it, design the technical solution of the utility model finally.

The terminal that main purpose of the present utility model is to provide a kind of anti-non-return tin and increases grasping force, the cross section of terminal is made as the U-shaped body, the two long side plates that comprise a central base sheet and curved Zhe, its latus inframedium respectively is provided with a protuberance in the appropriate location, the relative bending of an end at protuberance is provided with horizontal Zhe plate, and two horizontal Zhe plates are relative bondings, reach the purpose that prevents the scolding tin adverse current; The forward and backward side that holds in addition of terminal pie protrusion is respectively equipped with acute groove and obtuse angle groove, just can be sticked in the slot end, to become the place, first location between terminal and pedestal; Be provided with a card that protrudes in two side plate upper punches and end shell fragment another place, location as another buckle pedestal.

The terminal that another purpose of the present utility model is to provide a kind of anti-non-return tin and increases grasping force, the end of terminal two side plates is brought together and is formed suitable tapering, reaches the purpose that makes in the easier insertion pedestal of terminal.

A purpose more of the present utility model is to provide a kind of anti-non-return tin and increases the terminal of grasping force, and central base sheet becomes tool arc chord angle box-shaped body with two side sheet room Zhe, when reaching the slot of terminal insertion pedestal, and purpose that more can the tool fastening force.

The purpose of this utility model is achieved in that a kind of anti-non-return tin and increases the terminal of grasping force, the two long side plates that include central base sheet and curved Zhe, the cross section of terminal forms the U-shaped body, it is characterized in that: this two side plate is respectively to be provided with a protuberance with respect to the appropriate location, the relative bending of an end at protuberance is provided with horizontal Zhe plate, and two horizontal Zhe plates are relative bondings; The forward and backward side that holds in addition of this terminal pie protrusion is respectively equipped with acute groove and obtuse angle four grooves, is sticked in the slot end, to become the place, first location between terminal and pedestal; Be provided with a card that protrudes in two side plate upper punches and end shell fragment, as another place, location of buckle pedestal.

This terminal is brought together at the end of two side plates and is formed suitable tapering.This central base sheet and two side sheet rooms form arc chord angle.The end of this protuberance is formed with dentate margin.

Major advantage of the present utility model is:

1. because terminal of the present utility model is provided with central base sheet and biside plate makes its structural strength splendid, on two routine plates, be provided with protuberance especially, establish horizontal Zhe plate at the two and dock, just become a barrier structure, can prevent that other holds scolding tin to terminal from U-shaped body central authorities adverse current;
