Detailed Description

Referring to fig. 1 to 5, the electrical connector 100 includes a housing 110, a first terminal set 120, a second terminal set 160, and a spacer 140. The housing 110 has a first sidewall 112 and a second sidewall 116 spaced apart from the first sidewall 112, with a cavity 114 formed between the first and second sidewalls 112, 116. A first set of terminals 120 is disposed in the cavity 114 and adjacent the first sidewall 112. A second terminal set 160 is disposed in the cavity 114 adjacent the second sidewall 116. The spacer 140 is disposed in the cavity 114 and between the first terminal set 120 and the second terminal set 160. The housing 110 defines a depth direction 102, a width direction 104 perpendicular to the depth direction 102, and a height direction 106 perpendicular to the depth direction 102 and the width direction 104.

As shown in fig. 1, 3 and 4, the first terminal set 120 includes a first signal pair 123 and a first ground terminal 122. Each of the first ground terminals 122 is disposed between adjacent first signal pairs 123. The second terminal set 160 includes a second signal pair 165 and a second ground terminal 166. Each of the second ground terminals 166 is disposed between adjacent second signal pairs 165. The housing 110 has windows 108 formed in the first and second sidewalls 112 and 116 at locations corresponding to the first and second signal pairs 123 and 165 (the figure shows only the windows 108 in the first sidewall 112). . The spacer 140 is located closer to the first ground terminal 122 and the second ground terminal 166 than to the first signal pair 123 and the second signal pair 165. The spacer 140 may be in contact with the first and second ground terminals 122, 166 or, alternatively, the spacer 140 may be spaced apart from the first and second ground terminals 122, 166 by an air gap. The windows 108 provide air spaces for the first and second ground terminals 122, 166, which help to maintain signal integrity of the electrical connector 100.

The spacer 140 is electrically coupled to the first ground terminal 122 and the second ground terminal 166 as a resonance damping member to improve signal integrity of the electrical connector 100.

The first signal pair 123 and the first ground terminal 122 may lie in a first plane. The second signal pair 165 and the second ground terminal 166 may lie in a second plane. As shown in fig. 6 and 7, the spacer 140 has a base 141. A plurality of first ridges 142 protruding from the base 141 toward the first terminal set 120 are formed at one side of the base 141. A plurality of second ridges 146 protruding from the base portion 141 toward the second terminal group 160 are formed on the other side of the base portion 141. First notches 143 are formed between adjacent first ridges 142. Second notches 145 are formed between adjacent second ridges 146. Each of the first ridges 142 is aligned with a corresponding one of the first ground terminals 122 in the width direction 104 of the housing 110. Each of the second ridges 146 is aligned with a corresponding one of the second ground terminals 166 in the width direction 104 of the housing 110. Each of the first ridges 142 contacts a corresponding one of the first ground terminals 122, and each of the second ridges 166 contacts a corresponding one of the second ground terminals 166. Alternatively, each first ridge 142 is spaced apart from a corresponding one of the first ground terminals 122 by an air gap, and each second ridge 146 is spaced apart from a corresponding one of the second ground terminals 166 by an air gap.

As shown in FIGS. 8 and 9, the first frame 130 has side columns 137 and a plurality of first projections 133 facing the spacers 140 and notches 132 between each adjacent two of the first projections 133. the second frame 150 has second columns 153 and a plurality of second projections 155 facing the spacers 140 and notches 156 between each adjacent two of the second projections.each first ridge 142 of the spacers 140 is located within a corresponding one of the first notches 132 and each second ridge 146 of the spacers 140 is located within a corresponding one of the second notches 156. each first projection 133 and second projection 155 is disposed between a corresponding adjacent first ridge 143 and second ridge 145 of the spacers 140. the first columns 137 and first projections 133 are formed on the first IM L A120a toward the spacers 140. similarly, the second columns 153 and second projections 155 are formed on the second IM L A160a with second recesses 151 toward the spacers 140. the terminal portions of the first terminal group 120 located in the first recesses 139 are located relative to the terminal portions of the first terminal groups 160. the second terminal portions located between the second columns 153 and second projections 140 form second terminal groups 151 relative to the signal portions of the second terminal groups 151.

The first frame 130 has a first rib 131 facing the first sidewall 112 of the case 110. The second frame 150 has a second rib 157 facing the second sidewall 116 of the housing 110. The first rib 131 separates the first terminal set 120 from the first sidewall 112 of the housing 110. Second ribs 157 space second terminal set 160 from second sidewall 116 of housing 110.

First openings 1302 are formed between the first ribs 131, and the first terminal group 120 is partially exposed through the first openings 1302. Second openings 1508 are formed between the second ribs 157, and a portion of the second terminal set 160 is exposed through the second openings 1508.

As shown in fig. 10-15, the first set of terminals 120 is located a distance 120d from the first sidewall 112 of the housing 110. The second terminal set 160 is located a distance 160d from the second sidewall 116 of the housing 110. The first opening 1302 and the second opening 1508 are formed for an insert molding process of the IMPA120a, 160 a.

Fig. 14 and 15 show the positional relationship between the spacer 140 and the second ground terminal 166 and between the spacer 140 and the second signal pair 165. The positional relationship between the spacer 140 and the first ground terminal and the first signal pair is the same. As shown in fig. 14 and 15, 146d denotes a distance between the second ridge 146 of the spacer 140 and the second ground terminal 166. 145d represents the distance between the second notch 145 and the second signal pair 165, where 145d is greater than 146 d. In other words, the spacer 140 is located closer to the first ground terminal 122 of the first terminal set 120 and the second ground terminal 166 of the second terminal set 160 to enable electrical coupling between the spacer 140 and the first and second ground terminals 122, 166 and to improve signal integrity.

As shown in fig. 16, 17A and 17B, the electrical connector 100 includes a pair of fixing pieces 180 fixed to the housing 110 and engaged with the spacer 140. The first frame 130 has a pair of first grooves 138. The second frame 150 has a pair of second grooves 158. One of the securing tabs 180 fits into one of the first and second recesses 138, 158; another fixing piece 180 is installed in the another first groove 138 and the another second groove 158. Each securing tab 180 has barbs 182, 186, the barbs 182, 186 being embedded in the side walls 112, 116 of the shell 110 so that the securing tabs 180 are securely fastened to the shell 110. Each fixing piece 180 has a main body 181 and first and second bosses 182 and 186 protruding outwardly from the main body 181. The body 181 is placed in the grooves 138, 158, wherein the first ridge 182 and the second ridge 186 are pressed into the respective first groove 138 and second groove 158 of the first frame 130 and the second frame 150. Each fixing piece 180 has a middle portion 184 coupled to the spacer 140 to fix the spacer 140 to the case 110.

As shown in fig. 18 to 20, a partition 117 is formed between the first and second sidewalls 112 and 116 of the case 110, and the spacer 140 is seated on the partition 117. The baffle 117 has one or more recesses 118 formed thereon, in communication with the recesses 118 via the cavity 114. The spacer 140 may include one or more pins 148 protruding downward from a bottom surface thereof. Each pin 148 is disposed in one of the recesses 118, thereby preventing the spacer 140 from moving relative to the housing 110 in the depth direction 102 and the width direction 104.

In another embodiment, as shown in fig. 21-26, the electrical connector 200 includes a housing 210, first and second terminal sets 220, 260, and a spacer 240.

The spacer 240 is disposed in the cavity 214 and between the first terminal set 220 and the second terminal set 260.

The electrical connector 200 is a low profile structure having a relatively small height dimension compared to the previous embodiment. The first terminal set 220 and the second terminal set 260 are attached to the first sidewall 212 and the second sidewall 216, respectively, without requiring additional frame support. The first and second signal pairs 223, 265 are located farther from the spacer 240, and the ridges 242, 246 through which the spacer 240 protrudes are located closer to the first and second ground terminals 222, 266 to electrically couple with these ground terminals.

Similar to the previous embodiment, the electrical connector 200 includes a pair of fixing pieces 280 fixed to the housing 210 to fix the spacer 240 to the housing to ensure a correct positional relationship with the first terminal group 220 and the second terminal group 260.
