The contact connected by the method comprises a rivet-pressing part and a filling part arranged below the rivet-pressing part, wherein the basic shape of the filling part is the truncated cone shape, the outer part of which is big and the inner part of which is small, and the bottom part of the filling part is provided with a conical groove, the outer part of which is big and the inner part of which is small; the invention has the advantages of reducing the consumption of used materials and lowering manufacturing cost.
Description
Technical field
The invention belongs to the electric switch technical field, be specifically related to the contact that a kind of method of connecting terminal is connected with this method.
Background technology
Fig. 1 to Fig. 3 has shown a kind of method of traditional connecting terminal, and wherein Fig. 1 is the structural representation of traditional contact, and Fig. 2 is the structural representation of used contact, contact shown in Figure 1 base material and contact section bar; Fig. 3 is the structural representation of contact shown in Figure 2 base material when putting into the open-work of contact section bar.This kind contact base material comprises that the method for this kind connecting terminal mainly comprises: 1. process an open-work (4) and be ready to contact base material (1) on contact section bar (2); 2. contact base material (1) is inserted in the open-work (4), make the riveting portion (11) of contact base material (1) stretch out this open-work (4), clamp contact base material (1) then, and the direction riveting of A arrow exposes the riveting portion (11) of the contact base material (1) outside the open-work (4) in Fig. 1, thereby contact base material (1) is fixed in this open-work (4).
When the thickness b of contact section bar approached, the length a of the riveting portion of required contact section bar was also less, and it is comparatively feasible utilizing this kind method connecting terminal, and the contact quality is also reliable; But when the thickness of contact section bar is thicker, owing to need longer riveting portion that it is exposed from open-work, will consume more base material like this and make the contact, because the price of contact base material is more expensive, so can cause its cost to greatly increase, its sales promotion is had a negative impact.
Summary of the invention
First purpose of the present invention provides a kind of method that reduces the connecting terminal of used base material consumption.
Another object of the present invention provides a kind of contact of being made by this method.
The technical scheme that realizes first purpose of the present invention is: a kind of method of connecting terminal mainly may further comprise the steps:
1. be ready to contact base material and process a die cavity on the contact section bar, making this die cavity have a basic configuration is the poroid positioning area of truncated cone-shaped, and also is provided with the circular cone of a projection at the bottom center place of positioning area; 2. contact base material is inserted in the die cavity, along the direction riveting contact base material near die cavity, the bottom of contact base material is out of shape under the double action of riveting and circular cone extruding, fully be filled in the die cavity, thus the contact of acquisition forming.
The technical scheme that realizes another object of the present invention is: a kind of contact, comprise riveting portion and the filling part that is positioned at riveting subordinate side, the basic configuration of described filling part is the little truncated cone-shaped of outer imperial palace, and the bottom of described filling part also is provided with a conical socket that outer imperial palace is little.
The degree of depth of described bellmouth smaller or equal to filling part length 1/2nd and more than or equal to the sixth of filling part length.
The present invention has positive effect:
(1) basic configuration is set in die cavity is the poroid positioning area of truncated cone-shaped in the present invention, and the circular cone of a projection also is set at the bottom center place of positioning area; When the base material of riveting contact, the bottom of contact base material at first touches the awl point of described circular cone; Under the double action of riveting and the extruding of circular cone awl point, the filling part distortion of contact base material, the positioning area of the bottom of contact base material in die cavity stretches, until being full of whole die cavity; Because the positioning area of die cavity is a truncated conical shape, so contact base material is in case by after the riveting moulding, just firmly be fixed in the die cavity; Because die cavity of the present invention is a blind hole, used contact base material can be shorter, only need be full of die cavity and get final product, so compare with the method for traditional connecting terminal, has the less advantage of used base material consumption.
