The relay connector 100 can be connected to a flexible printed circuit board 200. The relay connector 100 includes a first housing 110 and a second housing 120. The first housing 110 has a main body 112 and a positioning portion 114 connecting to the main body 112. For example, the shape of the main body 112 of the first housing 110 can be rectangular, strip-shaped, or any shape, and the present utility model is not limited by the shape of the main body 112.

[0059] In some embodiments, the positioning portion 114 of the first housing 110 is located at the edge of the main body 112 of the first housing 110, and the main body 112 of the first housing 110 and the positioning portion 114 define a positioning opening O1 in a first direction D1. The first direction D1 can be the direction for installing or disassembling the first housing 110 and the second housing 120. The first housing 110 and the second housing 120 are shown as being snap-fitted up and down on the drawing. Taking the drawing as an example, the first direction D1 is the vertical direction.

[0060] In some embodiments, the second housing 120 is located on one side of the first housing 110, and the second housing 120 has a positioning block 122. When the first housing 110 and the second housing 120 are snap-fitted and installed along the first direction D1, the positioning block 122 of the second housing 120 can be snapped into the positioning opening O1 to secure the first housing 110 and the second housing 120 and complete the installation of the first housing 110 and the second housing 120. In addition, the first housing 110 and the second housing 120 define a circuit board opening O2 in another direction different from the first direction D1. For example, the circuit board opening O2 of the first housing 110 and the second housing 120 is located at the front side of the first housing 110 and the second housing 120, while the positioning opening O1 of the first housing 110 is located on the right side of the first housing 110.

[0061] In some embodiments, the flat cable of the flexible printed circuit board 200 can be electrically connected to an electronic screen or any electronic device, and the other end of the flexible printed circuit board 200 can be fixed in the relay connector 100 of the electrical connector structure 400 and electrically connected to the electrical connector 300 of the electrical connector structure 400 to form an electrical path from the electronic screen or any electronic device to the electrical connector 300. For example, when the electrical connector structure 400 of the present utility model is specifically used in a laptop computer, a personal computer, a smart phone, or a tablet computer, and especially as an electrical connector structure 400 for electrically connecting the flexible printed circuit board 200 of a screen or a component.

[0062] Specifically, the relay connector 100 of the electrical connector structure 400 has a circuit board opening O2 defined by a first housing 110 and a second housing 120. The circuit board opening O2 can accommodate a flexible printed circuit board 200. The flexible printed circuit board 200 is stabilized between the first housing 110 and the second housing 120 of the relay connector 100 through the circuit board opening O2. In this way, the electrical connector 300 can stably contact the flexible printed circuit board 200 through the relay connector 100, improving the conventional poor contact situation to enhance the performance of the electrical connector structure 400, such as the stability and correctness of signal transmission. In addition, the positioning block 122 of the second housing 120 of the relay connector 100 can be snapped into the positioning opening O1 of the first housing 110 to complete the installation of the first housing 110 and the second housing 120. When disassembling the first housing 110 and the second housing 120 of the relay connector 100, the positioning block 122 of the second housing 120 can be disengaged from the positioning opening O1 of the first housing 110 to achieve the benefit of quick installation and disassembly of the relay connector 100.

[0063] In some embodiments, a first region 1121 of the first housing 110 has a first outer sidewall 1123 and a second outer sidewall 1124 adjacent to the first outer sidewall 1123. A second region 1122 of the first housing 110 has a third outer sidewall 1125 adjacent to the second outer sidewall 1124. The first outer sidewall 1123 of the first housing 110 is perpendicular to the second outer sidewall 1124 of the first housing 110. The second outer sidewall 1124 of the first housing 110 is perpendicular to the third outer sidewall 1125 of the second housing 120. The first outer sidewall 1123 of the first housing 110 is parallel to the third outer sidewall 1125 of the second housing 120.

In Figures 4 to 6 , the first housing 110 has a snap member 116. The snap member 116 of the first housing 110 has a connecting portion 117 and a latching portion 118. The connecting portion 117 of the snap member 116 is disposed above the first housing 110. For example, the connecting portion 117 of the snap member 116 can be fixed to the first housing 110, and the latching portion 118 of the snap member 116 is connected to the connecting portion 117 of the snap member 116. The latching portion 118 of the snap member 116 of the first housing 110 can be snapped into the electrical connector 300 to stably connect the electrical connector 300 and the relay connector 100.

[0065] In some embodiments, the first housing 110 of the relay connector 100 is divided into a first region 1121 and a second region 1122 adjacent to the first region 1121. The positioning portion 114 of the first housing 110 is located in the first region 1121 of the first housing 110, and the second region 1122 of the first housing 110 is used to be snapped into the electrical connector 300 to stably connect the electrical connector 300 and the relay connector 100.

[0066] In some embodiments, in the first direction D1, the height H1 of the retaining wall 124 of the second housing 120 is greater than the height H2 of the engaging block 126 of the second housing 120. The overall size of the retaining wall 124 of the second housing 120 is greater than the overall size of the engaging block 126 of the second housing 120. In addition, the direction along the length extension of the first housing 110 and the second housing 120 is the second direction D2. In the second direction D2, the length T1 of the first region 1121 of the first housing 110 of the relay connector 100 is greater than the length T2 of the second region 1122 of the first housing 110. And the length T1 of the first region 1121 of the first housing 110 is approximately equal to the length of the second housing 120, so that the first housing 110 can be snap-fitted with the second housing 120.

[0067] In some embodiments, the second housing 120 has a retaining wall 124 and an engaging block 126. The positioning block 122 of the second housing 120 is located on the first side of the retaining wall 124. The engaging block 126 of the second housing 120 is located on the second side of the retaining wall 124 relative to the first side. For example, the positioning block 122 of the second housing 120 is located inside the retaining wall 124, and the engaging block 126 of the second housing 120 is located outside the retaining wall 124. In other words, the positioning block 122 of the second housing 120 is closer to the center of the second housing 120 than the engaging block 126.

[0068] Please refer to Figures 7 to 9 , Figure 7 is a cross-sectional view when the electrical connector structure 400 according to an embodiment of the present invention is connected to the flexible printed circuit board 200, Figure 8 is Figure 7 a side view of the electrical connector structure 400 and the flexible printed circuit board 200 when connected from another perspective, and Figure 9 is a schematic diagram when the electrical connector structure 400 according to an embodiment of the present invention is separated from the flexible printed circuit board 200. At Figures 7 to 9In this case, before the first housing 110 is snap-fitted to the second housing 120 in the first direction D1, the flexible printed circuit board 200 can be snap-fitted to the engaging block 126 of the second housing 120. The shape of the engaging block 126 of the second housing 120 corresponds to the inwardly recessed groove 210 of the flexible printed circuit board 200, so that the groove 210 can accommodate the engaging block 126 to stabilize the second housing 120 and the flexible printed circuit board 200.

[0069] Next, the first housing 110 can be snap-fitted to the second housing 120 in the first direction D1, so that the positioning portion 114 of the first housing 110 surrounds the positioning block 122 of the second housing 120, and the positioning block 122 of the second housing 120 is located in the positioning opening O1 of the first housing 110 to stabilize the first housing 110 and the second housing 120. In addition, the electrical connector 300 has contact terminals 320 located in the terminal groove 310. The contact terminals 320 of the electrical connector 300 can contact the flexible printed circuit board 200 in the relay connector 100 to electrically connect the flexible printed circuit board 200.

[0070] In summary, the circuit board opening O2 of the relay connector 100 of the electrical connector structure 400 can accommodate the flexible printed circuit board 200. The flexible printed circuit board 200 is stabilized in the relay connector 100 by the circuit board opening O2. In this way, the electrical connector 300 can stably contact the flexible printed circuit board 200 through the relay connector 100, which can improve the traditional poor contact situation to enhance the stability and correctness of signal transmission.
