ELECTRICAL CONNECTOR

Abstract

An electrical connector includes an insulation body, multiple terminals fixed to the insulation body, a conducting sheet fixedly to the insulation body, and a casing framing the insulation body. The conducting sheet includes a fixing portion, an elastic support portion bent and extending from the fixing portion, and a first contact portion goes forward from the elastic support portion and used for buckling a mating connector. The elastic support portion is used for pressing against the casing and forming a supporting point, so that the first contact portion further buckles the mating connector. The distance between the elastic support portion and the first contact portion is less than the distance between the retaining portion and the first contact portion, so that the insertion and removal force arm of the first contact portion is reduced, and the insertion and removal force of the conducting sheet is increased.

Description

FIELD OF THE INVENTION

The present invention relates to an electrical connector, and particularly to an electrical connector having a desirable insertion and removal force.

BACKGROUND OF THE INVENTION

An electrical connector in the related art includes a body having a mating cavity, two buckling elastic sheets disposed at two sides of the body and used for buckling a mating connector, and a metal casing disposed outside the body. The buckling elastic sheet generally has a fixing portion fixed to the body, a first contact portion extending forward from the fixing portion, protruding and stretching into the mating cavity to elastically buckle the mating connector, and a second contact portion bent and extending forward from the first contact portion and toward the metal casing. When the mating connector is inserted into the mating cavity, the first contact portion elastically buckles the mating connector, and the second contact portion presses against the metal casing. In this case, formed elastic buckling force arms separately have a first force arm and a second force arm, the first force arm is located between the fixing portion and the first contact portion, and the second force arm is located between the first contact portion and the second contact portion.

However, the buckling elastic sheet, the first force arm and the second force arm of this structure all affect the buckling force of the first contact portion, so the stability of buckling to the mating connector by the first contact portion is easily decreased. When the electrical connector and the mating connector are instantaneously mated, the buckling elastic sheet is easily instantaneously broken, thereby affecting the whole performance of the electrical connector.

Therefore, a heretofore unaddressed need exists in the art to address the aforementioned deficiencies and inadequacies.

The description will be made as to the embodiments of the present invention in conjunction with the accompanying drawings in FIGS. 1-6. In accordance with the purposes of this invention, as embodied and broadly described herein, this invention, in one aspect, relates to an electrical connector.

As shown in FIG. 1 and FIG. 2, an electrical connector 100 according to one embodiment of the present invention includes an insulation body 1, multiple terminals fixed to the insulation body 1, two conducting sheets 5 fixedly disposed at the insulation body 1, an insulation piece 6 disposed at the insulation body 1, and a casing 2 framing the insulation body 1.

As shown in FIG. 1 and FIG. 2, the multiple terminals include a first terminal group 3 and a second terminal group 4. The first terminal group 3 includes a first insulation block 31 and multiple first terminals 32, and the first insulation block 31 and the first terminals 32 form the first terminal group 3 by means of insert-molding. The first terminal 32 includes a first retaining portion 322 embedded in the first insulation block 31, a first welding portion 323 extending backward from the first retaining portion 322 out of the insulation of the body 1, and a first insertion portion 321 stretching forward from the first retaining portion 322 into a mating cavity 120. The second terminal group 4 includes a second insulation block 41 and multiple second terminals 42, and the second insulation block 41 and the second terminals 42 form the second terminal group 4 by means of insert-molding. The second terminal 42 includes a second retaining portion 422 embedded in the second insulation block 41, a second welding portion 423 extending backward from the second retaining portion 422 out of the insulation body 1, and a second insertion portion 421 stretching forward from the second retaining portion 422 into the mating cavity 120. The first and second terminal groups 3 and 4 are buckled to each other as a whole by means of protrusions (not labeled) and through-holes (not labeled) disposed on the first and second insulation blocks 31 and 41 and then are assembled into the insulation body 1.

As shown in FIGS. 1, 2 and 4, the insulation body 1 includes a base portion 11 and a mating portion 12 protruding forward from the base portion 11. The mating cavity 120 is depressed inward from the mating portion 12, so as to be inserted therein by a mating connector 200. Multiple receiving slots (not shown) accommodating the multiple first terminals 32 and second terminals 42 are disposed in the mating cavity 120. A front end of upper and lower side walls (not labeled) of the mating portion 12 is provided with a groove 122. Multiple accommodating slots 121 are disposed at a place corresponding to the groove 122. The accommodating slots 121 run through the insulation body 1 up and down, and the first insertion portions 321 and the second insertion portions 421 are separately correspondingly disposed at the accommodating slots 121, so as to provide a space for the first insertion portions 321 and the second insertion portions 421 to elastically move up and down. The insulation piece 6 is disposed at the groove 122 and sandwiched between the insulation body 1 and the casing 2, so as to prevent the first and second insertion portions 321 and 421 from contacting the casing 2, which causes a short circuit. Moreover, left and right side walls (not labeled) of the mating portion 12 are each provided with a holding slot 123. The holding slots 123 run backward from the mating portion 12 through the base portion 11. Each of the conducting sheets 5 is disposed in the corresponding holding slots 123. Further, the front end of the holding slot 123 is provided with a protruding portion 124 pressing against the casing 2, which provides a receiving space for lateral elastic movement of the conducting sheet 5, and meanwhile strengthens the strength of the front end of the mating portion 12. In other embodiments, the holding slot 123 may also only be disposed at one side of the mating portion 12, but the present invention is not limited thereto.

As shown in FIGS. 1, 3 and 4, the two conducting sheets 5 are separately disposed in the holding slots 123, and each of the conducting sheets 5 has a fixing portion 56 fixed to the insulation body 1. An elastic support portion 52 is bent and extends forward from the fixing portion 56 and toward the casing 2, then a first contact portion 51 extends forward from the elastic support portion 52, protrudes and stretches into the mating cavity 120. The elastic support portion 52 is used for pressing against the casing 2 to form a supporting point, so that the first contact portion 51 further buckles the mating connector 200. In this case, the force arm affecting the elastic buckling force of the first contact portion 51 is only an elastic segment (not labeled) between the elastic support portion 52 and the first contact portion 51, and therefore the conducting sheet 5 can be effectively prevented from being instantaneously broken. Meanwhile, when mating with the mating connector 200, the elastic support portion 52 may elastically glide front and back relative to the casing 2, thereby driving the first contact portion 51 to elastically glide front and back, such that the conducting sheets 5 keeps stable elastic contact with both the casing 2 and the mating connector 200 during mating process. Moreover, the first contact portion 51 and the elastic support portion 52 are disposed at the front end of the fixing portion 56, so as to reduce the force arm of the conducting sheet 5, and effectively increase the insertion and removal force of the conducting sheet 5. Further, a second contact portion 53 is bent and disposed at the tail end of the conducting sheet 5 toward the casing 2, and the second contact portion 53 contacts the casing 2, so as to perform grounding processing on electromagnetic interference generated between the first and second terminal groups 3 and 4. In other embodiments, only one conducting sheet 5 may be disposed correspondingly at one of the holding slots 123, but the present invention is not limited thereto.

As shown in FIGS. 1, 3 and 4, a stopping portion 54 protrudes from each of two sides of the conducting sheet 5, and is located between the first contact portion 51 and the elastic support portion 52. The stopping portion 54 is stopped at an inner wall of the corresponding holding slot 123, so as to prevent the conducting sheet 5 from excessively stretching into the mating cavity 120 due to elastic failure after frequent insertion and removal. Additionally, an urging portion 55 protrudes from the two sides of the conducting sheet 5, and is located between the elastic support portion 52 and the fixing portion 56. The width of the urging portions 55 is greater than the width of other parts of the conducting sheet 5. When mating with the mating connector 200, the urging portions 55 press against the casing 2 in the width direction up and down, so as to provide an insertion and removal supporting point for the conducting sheet 5, and further strengthen the insertion and removal force of the conducting sheet 5.

As shown in FIGS. 2, 3 and 5, the electrical connector 100 further includes a middle shielding sheet 50. The middle shielding sheet 50 is disposed in the insulation body 1 and is located between the first terminal group 3 and the second terminal group 4, to shield electromagnetic interference between the first terminal group 3 and the second terminal group 4. The fixing portions 56 integrally extends from the middle shielding sheet 50, that is, the middle shielding sheet 50 and the conducting sheets 5 are integrally formed, so as to help reduce processing steps. In other embodiments, the conducting sheets 5 and the middle shielding sheet 50 may also be separately molded, but the present invention is not limited thereto.

As shown in FIG. 4 and FIG. 5, before the electrical connector 100 and the mating connector 200 are mated, the elastic support portions 52 do not contact the casing 2. The first contact portions 51 protrude and stretch into the mating cavity 120, and the second contact portions 53 contact the casing 2. After the electrical connector 100 and the mating connector 200 are mated, the first contact portions 51 buckle the mating connector 200, and the mating connector 200 presses the conducting sheets 5, so that the elastic support portions 52 urge against the casing 2. In this case, the electromagnetic interference generated between the first and second terminal groups 3 and 4 may be directly subjected to grounding by the elastic support portions 52 without being grounded by means of the second contact portions 53, so as to shorten the return grounding path of the electromagnetic interference signal. Meanwhile, both the elastic support portions 52 and the second contact portions 53 contact the casing 2, so as to increase the contact area of the conducting sheet 5 and the casing 2, and effectively alleviate the electromagnetic interference (EMI) problem of the electrical connector 100, such that the electrical connector 100 better implements high frequency transmission. Furthermore, because the distance between the elastic support portions 52 and the first contact portions 51 is less than the distance between the urging portions 55 and the first contact portions 51, the force arm of the conducting sheets 5 is reduced, and the insertion and removal force of the conducting sheets 5 is effectively increased, so as to prevent the mating connector 200 from loosing and falling off due to the elastic fatigue occurring after the conducting sheets 5 are frequently inserted and removed.

Referring to FIG. 6, another embodiment of the present invention is shown, and a difference between this embodiment and the foregoing embodiment lies in that: when the electrical connector 100 is not mated to the mating connector 200, both the elastic support portions 52 and the second contact portions 53 contact the casing 2, thereby increasing the contact surface of the conducting sheets 5 and the casing 2, so as to alleviate the electromagnetic interference (EMI) problem of the electrical connector 100, and ensure effective high frequency transmission of the electrical connector 100. Moreover, because the elastic support portions 52 urge against the casing 2, the support point of the insertion and removal force of the electrical connector 100 is transferred from the fixing portions 56 to the elastic support portions 52, so as to reduce the insertion and removal force arm of the conducting sheet 5, and perform secondary strengthening on the insertion and removal force of the conducting sheets 5.

In summary, the electrical connector 100 according to certain embodiments of the present invention, among other things, has the following beneficial advantages.

(1) Each of the conducting sheets 5 has an elastic support portion 52 used for pressing against the casing 2 and forming a supporting point, so that the first contact portion 51 further buckles the mating connector 200. In this case, the force arm affecting the elastic buckling force of the first contact portion 51 is only an elastic segment between the elastic support portion 52 and the first contact portion 51, and therefore the conducting sheet 5 can be effectively prevented from being instantaneously broken. Meanwhile, when mating with the mating connector 200, the elastic support portion 52 may elastically glide front and back relative to the casing 2, thereby driving the first contact portion 51 to elastically glide front and back, such that the conducting sheets 5 keeps stable elastic contact with both the casing 2 and the mating connector 200 during mating process.

(2) Each of the conducting sheets 5 is provided with a fixing portion 56, an elastic support portion 52 is bent and extends from the fixing portion 56, and a first contact portion 51 extends forward from the elastic support portion 52. Because the distance between the elastic support portion 52 and the first contact portion 51 is less than the distance between the fixing portion 56 and the first contact portion 51, the insertion and removal force arm of the conducting sheet 5 is reduced, and the insertion and removal force of the conducting sheet 5 is effectively increased, so as to prevent the mating connector 200 from loosing and falling off due to the elastic fatigue occurring after the conducting sheet 5 is frequently inserted and removed.

(3) After the electrical connector 100 and the mating connector 200 are mated, the first contact portion 51 buckles the mating connector 200, and the mating connector 200 presses each of the conducting sheet 5, so that the elastic support portion 52 contacts the casing 2. In this case, the electromagnetic interference generated between the first and second terminal groups 3 and 4 may be directly subjected to grounding by the elastic support portion 52 without being grounded by means of the second contact portion 53, so as to shorten the return grounding path of the electromagnetic interference signal. Meanwhile, both the elastic support portion 52 and the second contact portion 53 contact the casing 2, so as to increase the contact area of the conducting sheet 5 and the casing 2, and effectively alleviate the electromagnetic interference (EMI) problem of the electrical connector 100, such that the electrical connector 100 better implements high frequency transmission.

(4) Each of the conducting sheets 5 is provided with a stopping portion 54 between the first contact portion 51 and the elastic support portion 52, and the stopping portion 54 is stopped at the corresponding holding slot 123, so as to prevent the conducting sheet 5 from excessively stretching into the mating cavity 120 due to elastic failure after frequent insertion and removal.

(5) The insulation piece 6 is disposed at the groove 122 and sandwiched between the insulation body 1 and the casing 2, so as to prevent the first and second insertion portions 321 and 421 from contacting the casing 2, which causes a short circuit.

The foregoing description of the exemplary embodiments of the invention has been presented only for the purposes of illustration and description and is not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in light of the above teaching.

The embodiments are chosen and described in order to explain the principles of the invention and their practical application so as to activate others skilled in the art to utilize the invention and various embodiments and with various modifications as are suited to the particular use contemplated. Alternative embodiments will become apparent to those skilled in the art to which the present invention pertains without departing from its spirit and scope.
