Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and particularly to electrical connectors.

Background Art

[0002] In related technologies, as an electrical connector for fitting with an electrical connection body (for example, a flexible printed circuit board, FPC), there is one including an insulating body, several conductive terminals, and a rotating cover plate. The rotating cover plate is rotatable between an open position and a closed position. When it is necessary to attach the flexible printed circuit board, the rotating cover body is opened, so that the insertion of the flexible printed circuit board into the electrical connector becomes easy. After the flexible printed circuit board is inserted to a predetermined position, the rotating cover body is rotated so as to press the conductive terminal, thereby realizing electrical contact between the conductive terminal and the flexible printed circuit board.

[0003] However, since the rotating cover plate may be easily loosened under the action of stress, it will affect the connection reliability between the electrical connector and the flexible printed circuit board.

[0027] Referring to Figures 1 to 15, the present invention discloses an electrical connector 100 for mating with an electrical connector, the electrical connector including, but not limited to, a flexible flat cable (FFC) or a flexible circuit board (FPC).

[0031] In the illustrated embodiment of the present invention, the first contact portion 2121 and the second contact portion 2221 are spaced apart along the first direction A1-A1. The first contact portion 2121 and the second contact portion 2221 may be offset from each other along the first direction A1-A1. Specifically, the first contact portions 2121 of several first conductive terminals 21 are arranged in a first row along the second direction A2-A2 (for example, left-right direction), and the second contact portions 2221 of several second conductive terminals 22 are arranged in a second row along the second direction A2-A2, with the first row and the second row being parallel to each other, and the second direction A2-A2 being perpendicular to the first direction A1-A1.

[0032] The rotating cover plate 3 is rotatable between an open position (shown in Figures 12 and 13) and a closed position (shown in Figures 14 and 15) relative to the insulating body 1. When the rotating cover plate 3 is in the optimal open position (e.g., upright), it forms a vertical relationship with the rotating cover plate 3 in the optimal closed position (e.g., horizontal). Pivot shafts 30 are provided on both sides of the rotating cover plate 3, and the pivot shafts 30 are rotatably attached to the insulating body 1.

[0033] The rotating cover plate 3 includes a first cam group 3a and a second cam group 3b, wherein the first cam group 3a includes several first cams 31 spaced apart on a first straight line along the second direction A2-A2, and the second cam group 3b includes several second cams 32 spaced apart on a second straight line along the second direction A2-A2, with the first and second straight lines being parallel to each other. The first cams 31 are housed in the first storage space 210, and the second cams 32 are housed in the second storage space 220.

[0034] As the rotating cover plate 3 rotates from the open position to the closed position, the first cam 31 and the second cam 32 come into contact with the first contact elastic arm 212 and the second contact elastic arm 222, respectively. When the rotating cover plate 3 reaches the closed position, the first contact portion 2121 and the second contact portion 2221 come into close contact with the electrical connector, thereby achieving an electrical connection.

[0035] Specifically, in the illustrated embodiment of the present invention, the first contact elastic arm 213 is provided with a first contact plane 2131, and the first contact elastic arm 212 is provided with a first contact slope 2122 facing away from the first contact portion 2121. The second contact elastic arm 223 is provided with a second contact plane 2231, and the second contact elastic arm 222 is provided with a third contact plane 2222 facing away from the second contact portion 2221.

[0036] In the illustrated embodiment of the present invention, the first cam 31 includes a first plane 311, a first inclined surface 312 facing away from the first plane 311, a second plane 313 perpendicular to the first plane 311, a second inclined surface 314 facing away from the second plane 313, a first arc-shaped surface 3151 connecting the first plane 311 and the second plane 313, a second arc-shaped surface 3152 connecting the second plane 313 and the first inclined surface 312, a third arc-shaped surface 3153 connecting the first inclined surface 312 and the second inclined surface 314, and a fourth arc-shaped surface 3154 connecting the second inclined surface 314 and the first plane 311. The first arc-shaped surface 3151, the second arc-shaped surface 3152, the third arc-shaped surface 3153, and the fourth arc-shaped surface 3154 are configured to contact the corresponding first contact elastic arm 213 or the first contact elastic arm 212 during the rotation of the rotating cover plate 3 from the open position to the closed position, thereby achieving smooth rotation.

[0037] The second cam 32 includes a third plane 321, a fourth plane 322 facing away from the third plane 321, a fifth plane 323 perpendicular to the third plane 321, a sixth plane 324 facing away from the fifth plane 323, a fifth arc-shaped surface 3251 connecting the third plane 321 and the fourth plane 322, a sixth arc-shaped surface 3252 connecting the fifth plane 323 and the fourth plane 322, a seventh arc-shaped surface 3253 connecting the fourth plane 322 and the sixth plane 324, and an eighth arc-shaped surface 3254 connecting the sixth plane 324 and the third plane 321. The fifth arc-shaped surface 3251, the sixth arc-shaped surface 3252, the seventh arc-shaped surface 3253, and the eighth arc-shaped surface 3254 are configured to contact the corresponding second contact elastic arm 223 or the second contact elastic arm 222 during the rotation of the rotating cover plate 3 from the open position to the closed position, thereby achieving smooth rotation.

[0038] Referring to Figures 12 and 13, when the rotating cover plate 3 is in the open position, the first plane 311 of the first cam 31 is in contact with the first contact plane 2131, the first inclined plane 312 is in contact with the first contact inclined plane 2122, and the third plane 321 of the second cam 32 is in contact with the second contact plane 2231. At this time, the first cam 31 is in contact with the first contact elastic arm 213 and the first contact elastic arm 212, and the second cam 32 is in contact with the second contact elastic arm 223, thereby holding the rotating cover plate 3 in the open position. In other words, the rotating cover plate 3 of the present invention can reduce the pressure force between the first conductive terminal 21 and the second conductive terminal 22 and the electrical connector while maintaining a hovering posture in the open position, allowing the electrical connector to be removed with just one hand, which is quick and convenient. Preferably, when the rotating cover plate 3 of the present invention is in the open position, no pressing force is generated on the electrical connector by the first conductive terminal 21 and the second conductive terminal 22, thus facilitating the removal or insertion of the electrical connector.

[0039] When the rotating cover plate 3 is in the closed position, the second plane 313 of the first cam 31 abuts against the first contact plane 2131, the second inclined plane 314 abuts against the first contact inclined plane 2122, the fifth plane 323 of the second cam 32 abuts against the second contact plane 2231, and the sixth plane 324 abuts against the third contact plane 2222. At this time, the first cam 31 is held between the first contact elastic arm 213 and the first contact elastic arm 212, and the second cam 32 is held between the second contact elastic arm 223 and the second contact elastic arm 222, thereby holding the rotating cover plate 3 in the closed position. The present invention is provided with the first cam 31 and the second cam 32, and the two groups of cams contact the first conductive terminal 21 and the second conductive terminal 22, respectively, so that the rotating cover plate 3 can always maintain a sealed state and the rotating cover plate 3 is less likely to loosen, while the first contact portion 2121 and the second contact portion 2221 can achieve uniform pre-pressure contact with the conductive portion of the electrical connector.

[0040] The first fixing portion 211 includes a first opening 2110 that penetrates the first fixing portion 211, and a first elastic interference portion 2111 that is located on one side of the first opening 2110 and protrudes from the first contact elastic arm 213, the first elastic interference portion 2111 elastically contacts the insulating body 1.

[0041] The second fixing portion 221 includes a second opening 2210 that penetrates the second fixing portion 221, and a second elastic interference portion 2211 located on one side of the second opening 2210 and protruding from the second contact elastic arm 223, the second elastic interference portion 2211 elastically contacting the insulating body 1. In the illustrated embodiment of the present invention, both the first opening 2110 and the second opening 2210 are T-shaped.

[0042] The present invention, by providing the first elastic interference portion 2111 and the second elastic interference portion 2211, significantly reduces the overall deformation of the upper and lower surfaces of the insulating body 1 caused by localized stress concentration due to rigid interference, and effectively prevents the risk of terminal detachment that may occur due to damage to the slot contact surface of the insulating body 1 due to rigid interference.

[0043] Furthermore, the insulating body 1 includes a reinforcing projection 12 located between the first contact elastic arm 212 and the first abutment elastic arm 213, thereby improving the structural strength of the insulating body 1 and minimizing deformation.

[0044] The second fixed portion 221 of the second conductive terminal 22 is provided with a locking recess 2212 that penetrates the second fixed portion 221 backward along the first direction A1-A1. Accordingly, the insulating body 1 includes a locking projection 13 that locks into the locking recess 2212.

[0045] Compared to the prior art, the electrical connector 100 of the present invention includes a rotating cover plate 3, the rotating cover plate 3 is rotatable between an open position and a closed position relative to the insulating body 1, the rotating cover plate 3 includes a first cam group 3a and a second cam group 3b, the first cam group 3a includes several first cams 31, and the second cam group 3b includes several second cams 32, and as the rotating cover plate 3 rotates from the open position to the closed position, the first cams 31 and the second cams 32 contact the first contact elastic arm 212 and the second contact elastic arm 222, respectively, so that when the rotating cover plate 3 reaches the closed position, the first contact portion 2121 and the second contact portion 2221 both make close contact with the electrical connector. In this way, the electrical connector 100 of the present invention has higher reliability.

[0046] The embodiments described above are for illustrative purposes only and do not limit the technical aspects described herein. Understanding of the invention should be based on the skills of the art.
