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, and grafting portion is fusiformis, and the lower extreme of grafting portion forms one section location portion, and the width ratio thickness of location portion is little, and the length of location portion is between 0.20mm ~ 0.30mm, and the top of location 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 same arc surface of radius, and the elastic through hole both sides form curved elastic part. The utility model discloses set up location portion and can ensure the accurate interface that inserts of terminal, be difficult for taking place the displacement, the length of location portion is short is difficult for taking place to warp, and elasticity portion is the arc, can reduce the terminal required pressure when inserting, and convenient grafting improves the connection stability and the reliability of exempting from welding terminal.

Description

Welding-free terminal

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.

The top of the existing welding-free terminal does not have a positioning function, and when the terminal is required to be pressed and inserted under great force, the top is easy to displace to cause dislocation, so that the terminal is inconvenient to press and is easy to damage terminals or electronic devices.

Disclosure of Invention

In view of this, an object of the present invention is to provide a welding-free terminal with convenient crimping and less possibility of dislocation.

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 downwardly extending who connects grafting portion forms one section location portion, and the width ratio thickness of location portion is little, and the length of location portion is between 0.20mm ~ 0.30mm, and the top of location portion forms and inserts the end, and the center of grafting portion forms the elasticity through-hole, and the upper end and the lower extreme of elasticity through-hole are the same arc surface of radius, and elasticity through-hole both sides form curved elasticity portion.

The utility model discloses further set up to insert the end including terminal surface and four inclined planes of being connected with lower terminal surface down, the lower extreme on inclined plane is inwards connected to down the terminal surface all around, and the upper end leans out.

The utility model discloses further set up to the medial surface and the lateral surface of elasticity portion are the cambered surface.

The utility model discloses further set up as the radius of the upper and lower both ends arc surface of elasticity through-hole is 0.13 mm.

The utility model discloses further set up to the thickness of grafting portion is 0.60 mm.

The utility model has the advantages that the positioning part formed by the downward extension of the lower end of the welding-free terminal can be placed in the interface of the electronic component before the terminal is inserted into the electronic component, and then the terminal is inserted into the interface of the electronic component, and the positioning part can ensure the terminal to be accurately inserted into the interface in the process, so that the displacement is not easy to occur; the length of the positioning part is short and is not easy to deform, the width of the positioning part is smaller than the thickness, and the insertion end is arranged at the top of the positioning part, so that the positioning is facilitated; the elastic part is arc-shaped, so that the pressure required when the terminal is inserted can be reduced, the terminal is convenient to insert, and the connection stability and reliability of the welding-free terminal are improved.
