Abstract

The utility model relates to a crimp type conductive terminal, which comprises a sleeve, two contact-joint components, and an elastic component, the sleeve adopts two-part type design and is composed of a first body and a second body, wherein one end of the first body and the second body is respectively pre-formed with an opening, the two contact-joint components are arranged in the sleeve and respectively provided with a contact part, the contact parts of the two contact-joint components respectively pass through the openings of the first body and the second body and then are extended out from the two ends of the sleeve, the elastic component is arranged in the interior of the sleeve and also located between the two contact-joint components, the elastic component can prop the two contact-joint components to make the contact part be elastically extended out from the two ends of the sleeve; thereby the aperture of the opening of the sleeve not formed by riveting is easy to be controlled, no over-big or over-small aperture occurs, the length of the inner wall of the opening of the sleeve can be lengthened appropriately so as to provide good support force for the contact-joint components, thereby preventing the contact-joint components from being subject to lateral force so as to produce deflection.

Description

The compression joint type conducting terminal

Technical field

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

Background technology

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 sleeve 10a, and touches an element 20a and a

flexible member

30a, and 10a is one-body molded with metal material for this sleeve, is hollow columnar, this sleeve 10a front end is the opening shape, and the rear end is a closed.This touches element 20a and also makes with metal material, this flexible member 30a and this touch element 20a and insert this sleeve 10a inside by this sleeve 10a front end in regular turn, then this sleeve 10a front end is given riveted and make the opening 11a that forms a sudden contraction shape, this is touched element 20a to the opening 11a of this sudden contraction shape of mat and this flexible member 30a is positioned this sleeve 10a inside, this touches element 20a front end and passes this opening 11a, makes this touch element 20a front end elasticity by this flexible member 30a pushing tow and stretches out this sleeve 10a front end.

When reality is used, this sleeve 10a rear end can utilize surface adhering technology (SMT) or perforation (through hole) mode to fix and be electrically connected on the circuit board, this touches element 20a front end and can be crimped on the contact of desiring to test, make the signal on this contact be passed on the circuit board work of testing by this.

In addition, this sleeve 10a rear end can be electrically connected at a device, and this is touched element 20a front end is crimped on another device, reaches the effect that this stream oriented device electrically connects by this.

Only, above-mentioned known compression joint type conducting terminal, the aperture of the opening 11a of this sleeve 10a front end is wayward, there is the excessive or too small situation in aperture to take place easily, touch element 20a when the aperture is excessive and become flexible easily, rock, touch element 20a elasticity when the aperture is too small and be obstructed, be difficult to flexible swimmingly.

Moreover, this opening 11a touches element 20a with this and contacts length partly, it generally is wall thickness dimension for sleeve 10a, because this sleeve 10a wall thickness is very thin, relative contact length partly is then quite limited, so be difficult to provide this to touch the preferable support force of element 20a, especially touch element 20a when bearing side force at this, as easy as rolling off a log crooked.

Be with, as from the foregoing, above-mentioned known compression joint type conducting terminal on reality is used, obviously has inconvenience and exists with disappearance, and remain to be improved.
