Abstract
The utility model relates to an exempt from welding terminal, including interconnect's basal portion and grafting portion, the basal portion is located grafting portion top, grafting portion is fusiformis, and the lower extreme of grafting portion forms and inserts the end, and the center of grafting portion forms elastic through hole, and elastic through hole's upper end and lower extreme are the arc surface, and elastic through hole's lower extreme arc surface's radius is greater than the radius of upper end arc surface, and elastic through hole's both sides form the elasticity portion, and the lower extreme width of elasticity portion is little, and the upper end width of elasticity portion is big. The utility model discloses an easy deformation of lower extreme makes things convenient for the terminal to insert, and upper end non-deformable prevents that the terminal from extracting easily, improves the connection stability and the reliability of exempting from welding terminal.
Description
Technical Field
The utility model relates to an exempt from welding terminal belongs to the connector field.
Background
The connection of two electronic devices in an automobile is usually realized by welding or pressing. The crimping type connection mode is a novel connection mode gradually replacing a traditional welding type connection mode, has the environmental protection advantages of no welding and less environmental pollution, and is more convenient to connect between electronic devices and high in assembly efficiency.
Exempt from the welding terminal center to set up the elasticity through-hole, realize the grafting of terminal through the inside compression deformation of elasticity through-hole, the lower extreme of the elasticity through-hole of present exempting from the welding end is narrower than the upper end, when the terminal is impressed and is connected, the narrow deflection of elasticity through-hole width of lower extreme initial segment is little, difficult discovery is out of shape, the bigger pressure that needs just can insert, and the more easily deformation of wideer upper end when extracting, consequently the extraction power that needs is little, extract easily, influence connection stability.
Disclosure of Invention
In view of this, an object of the present invention is to provide a soldering-free terminal that is convenient to crimp and is not easy to be pulled out.
In order to realize above mesh, the utility model discloses an exempt from welding terminal, including interconnect's basal portion and grafting portion, the basal portion is located grafting portion top, grafting portion is fusiformis, and the lower extreme that connects grafting portion forms and inserts the end, and the center of grafting portion forms elastic through hole, and elastic through hole's upper end and lower extreme are the arc surface, and elastic through hole's lower extreme arc surface's radius is greater than the radius of upper end arc surface, and elastic through hole's both sides form the elasticity portion, and the lower extreme width of elasticity portion is little, and the upper end width of elasticity portion is big.
The welding-free terminal is provided with the elastic through hole in the center of the inserting part, the radius of the arc surface at the lower end of the elastic through hole is larger than that of the arc surface at the upper end of the elastic through hole, the width of the lower end of the elastic part is small, the width of the upper end of the elastic part is large, when the lower end of the elastic through hole is inserted, the space for compressing the lower end of the elastic through hole to the middle is large, the width of the lower end of the elastic part is small, the pressure required by compression; the width of the arc surface at the upper end of the elastic through hole is small, the compression space is small, the width of the upper end of the elastic part is large, the pressure required by compression is large, the pulling force required when the elastic part is pulled out is large, and the elastic part can be effectively prevented from being separated.
The utility model is further arranged in that the inserting end comprises a lower end face and four inclined planes connected with the lower end face, the lower end of the inclined planes is inwards connected to the lower end face, and the upper end leans outwards. The insertion end forms a pointed end through four inclined planes, so that the insertion is convenient.
This practicality further sets up as the radius of the lower extreme arc surface of elasticity through-hole is the twice of upper end arc surface radius.
The radius of the lower end arc surface of the elastic through hole is set to be 0.20 mm; the radius of the upper end circular arc surface is 0.10 mm.
This practicality sets up specifically to the thickness of grafting portion is 0.80 mm.
The beneficial effects of the utility model are that exempt from welding terminal's lower extreme easy deformation, make things convenient for the terminal to insert, upper end non-deformable prevents that the terminal from extracting easily, improves the connection stability and the reliability of exempting from welding terminal.
