The present invention relates to an electrical connector, and more particularly to an electrical connector that can be used in place of a conventional resilient probe connector.

Electrical connectors are widely used in electronic devices to interconnect different electronic devices. The prior electrical connector includes a plurality of conductive terminals for connecting the accessory connectors or for mounting on the electronic device and an insulative housing for receiving the plurality of conductive terminals. As signal transmission progresses toward high speed and high frequency, probe type terminals are used to ensure a reliable connection between the conductive terminals and their contact parts. However, the probe type terminal is relatively expensive, which is disadvantageous for reducing the manufacturing cost of the electrical connector.

Therefore, it is indeed necessary to design a new technical solution to overcome the aforementioned drawbacks.

The technical problem to be solved by this creation is to provide an electrical connector that can be used to replace the conventional elastic probe connector, which can save cost while ensuring stable contact.

In order to solve the foregoing technical problem, the present invention may adopt the following technical solution: an electrical connector including an insulative housing and a plurality of elastic terminals held on the insulative housing, the insulative housing including oppositely disposed upper surfaces, lower surfaces, and plural a terminal receiving groove penetrating the upper and lower surfaces, the elastic terminal includes a spring portion that is bent and elastic in an up-and-down direction, and a fixing portion that extends downward from the spring portion, the fixing portion is held by In the terminal receiving groove, the spring portion extends out of the upper surface of the insulating body, the upper end of the spring portion is provided with a contact portion, and the lower end of the fixing portion is integrally stamped downward to form an abutting portion, and the butting portion An abutting surface exposed on a lower surface of the insulating body is provided, and the abutting surface is flush with the lower surface.

Hereinafter, referring to the first to fifth figures, the present invention provides an electrical connector 100 that can be used in place of a conventional elastic probe connector, comprising an insulative housing 1 and a plurality of resilient terminals 2 held by the insulative housing 1 The insulative housing 1 includes an upper surface 11 , a lower surface 12 , and a plurality of terminal receiving slots 13 extending through the upper and lower surfaces 11 , 12 . The elastic terminal 2 includes a bent portion and has an upper and lower direction. The elastic spring portion 21 and the fixing portion 22 extending downward from the spring portion 21, the fixing portion 22 is retained in the terminal receiving groove 13, and the spring portion 21 extends out of the insulating body 1 The upper end of the spring portion 21 is provided with a contact portion 211, and the lower end of the fixing portion 22 is integrally stamped downward to form an abutting portion 220, and the abutting portion 220 is provided to be exposed on the lower surface 12 of the insulative housing 1. The abutting surface 221 is flush with the lower surface 12 . In the embodiment, the electrical connector 100 includes five elastic terminals 2, the elastic terminals 2 are arranged in a straight line, and the elastic terminals 2 are integrally injection molded with the insulating body 1.

Referring to the second and fourth figures, a horizontal direction perpendicular to the up and down direction is defined, and the spring portion 21 is provided with an "S" type bend in which the opening direction is horizontal. The fixing portion is provided with a "U"-shaped bending in which the opening direction is the horizontal direction. In this embodiment, the "S" type bending and the "U" type bending are connected end to end by a downwardly extending connecting portion 222, the "S" type bending, the connecting portion 222 and the "U" The type of bending together forms a "U"-shaped bend in which the other opening direction is opposite to the opening direction of the "U"-shaped bent.

Referring to the first, second and sixth figures, the contact portion 211 extends in the horizontal direction, and the insulative housing 1 includes a lug 141 disposed on the side surface 14, and the lug 141 is provided on the lug 141. The electrical connector 100 is mounted to a mounting hole 1411 of the electronic device 200. As shown in the sixth to eighth embodiments, after the electrical connector 100 is mounted on the electronic device 200, the contact portion 211 can directly abut the metal piece 202 on the circuit board 201 in the electronic device 200. Thereby, a stable electrical contact is achieved, and since the spring portion 21 has a certain elasticity in the mating direction, the elastic terminal 2 can achieve the same contact effect as the conventional probe type terminal.

As shown in the third to fifth figures, the lower end of the fixing portion 22 includes a horizontally disposed flat plate portion 223, the flat plate portion 223 is retained in the insulative housing 1, and the abutting portion 220 is the flat plate portion. 223 is stamped down from its thickness direction. A cross section of the terminal receiving groove 13 on the lower surface 12 is covered by the mating surface 221 . In the present embodiment, the abutting faces 221 exposed on the lower surface 12 of the insulative housing 1 are disposed in a circular shape. The flat plate portion 223 is provided with a tail portion 224 embedded in the insulating body. Referring to the ninth and tenth views, when the electrical connector 100 is mounted on the electronic device 200, the appearance of the mating surface 221 is consistent with the appearance of a conventional elastic probe connector, and functionally, the docking The face 221 can also be in direct contact with the contact point 301 on the external device 300. This creation uses a lower cost elastic terminal instead of a more expensive elastic probe terminal, which is conducive to saving the cost of the electrical connector.

The above is only a preferred embodiment of the present invention, and should not limit the scope of the creation. Any equivalent or obvious modification made by the scope of the patent application and the contents of the specification should still belong to the original creation patent. Covered by the scope.
