Abstract

A crimping conducting terminal contains a shell, a touch component and an elastic component. A cut is arranged at the front end of the shell. The touch component is provided with a front end part and a rear end part. The outside diameter of the rear end part is a little longer than the outside diameter of the front end part. The rear end part is held in the shell and the elastic component is put in the shell. One end of the elastic component leans against the rear end part of the touch component, making the front end part of the touch component extend out of the front end of the shell elastically. An inward contracting neck is formed at the front end of the shell and the cut is formed inside the neck. The front end part of the touch component runs through the cut inside the neck and extends out of the front end of the shell. Therefore, the length of the neck can be added as required so as to form a larger contact area between the neck and the touch component to provide better bearing force for the touch component, thereby avoiding deflection of the touch component when bearing side direction force.

Description

The compression joint type conducting terminal

Technical field

The utility model is about a kind of compression joint type conducting terminal, refers to a kind of compression joint type conducting terminal that can be used as the probe of test contacts or be used to electrically connect stream oriented device especially.

Prior art

See also Fig. 1, known compression joint type conducting terminal, can be used as the probe of test contacts, or be used to electrically connect stream oriented device, this compression joint type conducting terminal includes a housing 10a, a contact element 20a and an elastic component 30a, and 10a is one-body molded with metal material for this housing, is hollow columnar, this housing 10a front end is the opening shape, and the rear end is a closed.This contact element 20a also makes with metal material, this elastic component 30a and this contact element 20a insert this housing 10a inside by this housing 10a front end successively, then this housing 10a front end being given riveted makes and forms a less opening 11a, by this less opening 11a this contact element 20a and this elastic component 30a are positioned this housing 10a inside, and this contact element 20a front end passes this opening 11a, and makes this contact element 20a front end elasticity stretch out this housing 10a front end by this elastic component 30a pushing tow.
