This application claims the benefit of the filing date under 35 U.S.C. § 119(a)-(d) of Chinese Patent Application No. 201810193981.4, filed on Mar. 9, 2018.
The present invention relates to a connector and, more particularly, to a conductive terminal of the connector.
A connector generally comprises an insulation body, a conductive terminal, and a terminal position assurance (TPA). The conductive terminal is mounted in a mounting groove of the insulation body and the TPA is inserted into the mounting groove of the insulation body from the rear of the insulation body. A front end surface of the TPA is in contact with a rear end surface of an insulation sheath crimping portion of the conductive terminal, which is crimped to an insulation sheath of a wire. The TPA pushes the conductive terminal forward, thereby holding the conductive terminal in the insulation body to prevent the conductive terminal from loosening.
The TPA must be in contact with the rear end surface of the insulation sheath crimping portion of the conductive terminal to hold the conductive terminal. However, since an area of the rear end surface of the insulation sheath crimping portion of the conductive terminal is small, a contact area between the TPA and the rear end surface of the insulation sheath crimping portion is small, and therefore the TPA cannot reliably hold the conductive terminal in the insulation body. In addition, the insulation sheath of the wire has a certain elasticity. When the insulation sheath crimping portion of the conductive terminal is crimped against the insulation sheath of the wire, the crimping portion of the conductive terminal may be caught into the insulation sheath of the wire, which may cause the TPA to be not in contact with the insulation sheath crimping portion of the conductive terminal, causing failure of the TPA.
A conductive terminal adapted to be mounted in an insulation housing of a connector includes a mating portion disposed at a front of the conductive terminal and adapted to engage a mating terminal of a mating connector, a crimping portion disposed at a rear of the conductive terminal and adapted to be crimped onto a wire, and a pressing portion disposed at a rear end of the crimping portion and extending outward. The conductive terminal is adapted to be held in the insulation housing by pushing the pressing portion.
The invention will now be described by way of example with reference to the accompanying Figures, of which:
Embodiments of the present invention will be described hereinafter in detail with reference to the attached drawings, wherein like reference numerals refer to like elements. The present invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided so that the disclosure will convey the concept of the invention to those skilled in the art. In addition, in the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawing.
A connector according to an embodiment, as shown in
The conductive terminal 200, as shown in
In an embodiment, the entire conductive terminal 200 may be a single metal component made of a single sheet of metal. For example, the conductive terminal 200 may be made of a single sheet of metal through a process such as stamping, bending, or the like.
As shown in
The second crimping portion 230, as shown in
In the embodiment shown in
The mating portion 210 of the conductive terminal 200, as shown in
A conductive terminal 200′ according to another embodiment is shown in
A conductive terminal 200″ according to another embodiment is shown in
In the embodiments of the conductive terminal 200, 200′, 200″ described above, the pressing portion 240 extending outward is formed at the rear end of the crimping portion 230, so that the TPA 300 may reliably hold the conductive terminal 200 in the insulation housing 100 by pushing the pressing portion 240.
