DETAILED DESCRIPTION OF THE EMBODIMENT(S)

(5) The technical solutions of the disclosure will be described in further details by means of embodiments in conjunction with the accompanying drawings. In the specification, the same or similar reference numerals indicate the same or similar parts. The following description on the embodiments of the disclosure with reference to the drawings is intended to explain the overall concept of the disclosure and should not be construed as a limitation to the disclosure.

(6) In addition, for the purpose of explanation, numerous specific details are set forth in the following detailed description so as to provide a thorough understanding of embodiments of the present disclosure. Obviously, however, one or more embodiments may also be implemented without these specific details. In other instances, well-known structures and devices are shown in an illustrative manner so as to simplify the drawings.

(7) With reference to FIG. 1, an electrical connector 100 according to the invention is shown and mounted to a circuit board 10. As shown, approximately three electrical connectors 100 are mounted to the circuit board 10. However, one skilled in the art should appreciate that one or more electrical connectors 100 could be used.

(8) In an exemplary embodiment of the invention, as shown in FIGS. 1-3, the entire electrical connector is constituted by only one conductive terminal 100 on which a top flat surface 111 adapted to be sucked by a suction nozzle (not shown) is formed.

(9) In the shown embodiment, as shown in FIGS. 1-3, the conductive terminal 100 includes a first end 110, a second end 120 opposite to the first end 110, and an intermediate connecting portion 130 connecting the first end 110 and the second end 120.

(10) In an exemplary embodiment of the invention, the top flat surface 111 is disposed on top of one of the first end 110 and the second end 120 of the conductive terminal 100.

(11) As shown in FIGS. 1-3, the first end 110 and the second end 120 of the conductive terminal 100 have a flat bottom surface adapted to be soldered to the circuit board 10 using surface mounting technology (SMT).

(12) As shown in FIGS. 1-3, the top flat surface 111 is disposed on the top of the first end 110 of the conductive terminal 100. The second end 120 of the conductive terminal 100 is configured to be crimped onto a conductive wire 200.

(13) The second end 120 of the conductive terminal 100 is annular shaped, so that the conductive wire 200 can be inserted into the conductive terminal 100 through the annular second end 120.

(14) As shown in FIGS. 1-3, the conductive terminal 100 further includes a resilient cantilever 140 that is adapted to be in resiliently electrical contact with an exposed conductor core 210 of the conductive wire 200 that is inserted into the conductive terminal 100.

(15) In an exemplary embodiment of the invention, a base of the resilient cantilever 140 is integrally connected to the second end 120. The resilient cantilever 140 extends toward the first end 110.

(16) In the shown embodiment, as shown in FIGS. 1-3, a receiving groove 131 is formed in the intermediate connecting portion 130 and extends in an insertion direction of the conductive terminal 100. The receiving groove 131 receives the conductor core 210. The resilient cantilever 140 extends into the receiving groove 131 to make electrical contact with the conductor core 210.

(17) In an exemplary embodiment of the invention, as shown in FIGS. 1-3, the width of the resilient cantilever 140 gradually decreases as it extends from its base to a free end thereof. As a result, the varying width improves the resilience of the resilient cantilever 140 and guarantees connection strength of the base of the resilient cantilever 140.

(18) In an exemplary embodiment of the invention, as shown in FIGS. 1-3, the entire conductive terminal 100 is formed by cutting, punching, and bending processes of a single piece of metal material or a section of strip metal material.

(19) It should be appreciated for those skilled in this art that the above embodiments are intended to be illustrative, and can be improved by those skilled in the art. The structures described in the various embodiments may be freely combined without a confliction of the structure or principle.

(20) Although exemplary embodiments of the present disclosure are described in detail with reference to the attached drawings, the embodiments disclosed in the drawings are intended to be illustrative to the preferable embodiments of the present disclosure and should not be construed as a limitation to the present disclosure.

(21) Although several exemplary embodiments of the overall concept of the present closure have been shown and described, it would be appreciated by those skilled in the art that various changes or modifications may be made in these embodiments without departing from the principles and spirit of the disclosure, the scope of which is defined in the claims and their equivalents.

(22) It should be noted that the word comprising or including does not exclude the presence of elements or steps other than those listed in a claim, unless such exclusion is explicitly stated. The word a or an preceding an element does not exclude the presence of a plurality of such elements, unless such exclusion is explicitly stated. Further, the reference signs should not be construed as a limitation to the protection scope of the disclosure.
