[0040] See also Figure 1 、 2 and Figure 3The present invention provides an electrical connector 100 for connecting with a conductive member 200. The conductive member 200 can be selected from electronic components such as a flat cable (FFC) and a flexible printed circuit (FPC). The electrical connector 100 includes an insulating carrier 110, a plurality of terminals 120, at least one grounding terminal 130, and a cover 140. The terminals 120 and the grounding terminal 130 are disposed in the insulating carrier 110. The terminals 120 are used to contact a plurality of pins 210 of the conductive member 200, and the grounding terminal 130 is used to contact a conductive plate 220 of the conductive member 200. In this embodiment, the pins 210 and the conductive plate 220 are respectively located on different surfaces of the conductive member 200, but the present invention is not limited thereto.

[0041] See also Figure 2 and Figure 3 The insulating carrier 110 has a bottom 111, two side portions 112, a top 113, and a receiving space 114. The two side portions 112 are respectively disposed on two sides of the bottom 111. The receiving space 114 is located between the two side portions 112. The top 113 is disposed across the receiving space 114 and, combined with the side portions 112, the receiving space 114 has a first opening 114a and a second opening 114b respectively located on two sides of the top 113. The receiving space 114 is used to accommodate the conductive component 200 after the conductive component 200 is plugged into the electrical connector 100.

[0042] See also Figure 2 and Figure 4 The terminals 120 are disposed in the accommodating space 114. The electrical connector 100 is electrically connected to the pins 210 of the conductive member 200 located in the accommodating space 114 and the substrate 300 (such as a circuit board or a glass substrate) located outside the electrical connector 100 through the terminals 120. In this embodiment, the terminals 120 are accommodated in the accommodating space 114 through the second opening 114b. Each of the terminals 120 has a conductive arm 121. The bottom 111 has a plurality of limiting grooves 111a. Each of the conductive arms 121 is respectively disposed in each of the limiting grooves 111a. Each of the conductive arms 121 has a conductive end 121a. The conductive end 121a protrudes from the bottom 111 and is located in the accommodating space 114. The conductive end 121a is used to contact each of the pins 210 of the conductive member 200.

[0043] See also Figure 2 and Figure 4In this embodiment, each terminal 120 has a fixed arm 122, and the fixed arm 122 is integrated with the conductive arm 121. An insertion space 123 is provided between the fixed arm 122 and the conductive arm 121. The insertion space 123 has a height H. The insertion space H is used to accommodate the conductive member 200. The conductive member 200 has a thickness D, and the thickness D is less than the height H, so that the fixed arm 122 does not contact the conductive plate 220 of the conductive member 200.

[0044] See also Figure 1 、 2 , 5, 6 and Figure 7 The ground terminal 130 has a plug-in portion 131, a joint portion 132, an extension portion 133, a limit portion 134 and a contact portion 135. The joint portion 132 and the extension portion 133 are respectively connected to the plug-in portion 131, the limit portion 134 and the contact portion 135 are respectively connected to the extension portion 133. Figure 2 、 5 and Figure 7 The plug-in portion 131 is plugged into the side portion 112. Figure 1 、 2 and Figure 5 The joint portion 132 is exposed at the bottom 111 to be combined with the substrate 300. Figure 2 and Figure 7 The extension portion 133 is located below the top portion 113, and the limiting portion 134 is located outside the top portion 113. Preferably, the top portion 113 has a limiting groove 113a, and the limiting portion 134 is accommodated in the limiting groove 113a to fix the limiting portion 134 to prevent the extension portion 133 from bending and deforming when inserting / extracting the conductive component 200, thereby causing the contact portion 135 to deflect or bend.

[0045] See also Figure 2 and Figure 7 The contact portion 135 is located in the accommodating space 114. In this embodiment, the contact portion 135 of the ground terminal 130 is accommodated in the accommodating space 114 via the first opening 114a. The contact portion 135 is used to contact the conductive plate 220 of the conductive member 200 located in the accommodating space 114. Preferably, the contact portion 135 has an elastic arm 135a facing the bottom 111. The elastic arm 135a has an arc-shaped contact end 135b. The arc-shaped contact end 135b is used to contact the conductive plate 220 of the conductive member 200 and contact the conductive plate 220 through the arc-shaped contact end 135b, so as to reduce the contact area and friction between the elastic arm 135a and the conductive plate 220 during the process of plugging the conductive member 200 into the electrical connector 100, thereby reducing the force applied when plugging / unplugging the conductive member 200.

[0046] See also Figure 2 、 4 and Figure 7 The cover 140 is rotatably disposed in the accommodating space 114 to cover the contact portions 135 of the terminals 120 and the grounding terminal 130 and to contact the conductive member 200 located in the accommodating space 114. In this embodiment, the cover 140 has a pivot 141 and a pushing portion 142. The cover 140 is pivotally connected to the insulating carrier 110 by the pivot 141, so that the cover 140 can be lifted up or covered on the insulating carrier 110 using the pivot 141 as a rotation axis. When the cover 140 is covered on the insulating carrier 110, the pushing portion 142 contacts the conductive member 200 in the accommodating space 114, so that each of the pins 210 of the conductive member 200 contacts each of the conductive arms 121.

[0047] See also Figure 2 and Figure 7 The insulating carrier 110 has a stopping portion 115, which is disposed in the accommodating space 114 and located between the conductive arm 121 and the fixed arm 122. In this embodiment, the stopping portion 115 is arranged across the accommodating space 114 and combined with the side portion 112, and the limiting grooves 111a and the conductive arms 121 are located below the stopping portion 115. The stopping portion 115 is used to block the conductive member 200 along the first direction X, and the pushing portion 142 is used to press the conductive member 200 in the accommodating space 114 along the second direction Y to prevent the conductive member 200 from bending and causing the conductive plate 220 to contact the fixed arm 122 and cause a short circuit.

[0048] See also Figure 8 The bottom 111 has at least one limiting protrusion 111b. When the conductive member 200 is plugged into the electrical connector 100, the limiting protrusion 111b is used to fit the positioning hole 230 of the conductive member 200 to prevent the conductive member 200 from being separated from the electrical connector 100. Figure 7 and Figure 8 When the conductive member 200 is not inserted into the predetermined position and the positioning hole 230 is not sleeved on the limiting protrusion 111b, the cover 140 will not be able to cover the insulating carrier 110. Therefore, it is convenient for the operator to observe whether the conductive member 200 is inserted into the predetermined position from the outside of the electrical connector 100. Figure 9 Preferably, the side portion 112 has a positioning groove 112a, and the cover body 140 has a positioning protrusion 143. When the cover body 140 is covered on the insulating carrier 110, the positioning protrusion 143 can be stuck in the positioning groove 112a to prevent the cover body 140 from being lifted up by improper external force.
