[ detailed description ] embodiments

Referring to fig. 1 to 16, the stackable connector 10 of the present invention includes an upper connector 100 and a lower connector 200 stacked one on top of the other in a direction perpendicular to a circuit board (not shown). The upper connector 100 includes an upper terminal module 110 and an upper metal shell 130 covering the upper terminal module 110. The lower connector 200 includes a lower terminal module 210 and a lower metal shell 230 covering the lower terminal module 210. Referring to fig. 15-16, the upper terminal module 110 includes two rows of upper terminals 112, an upper shielding plate 114 disposed between the two rows of upper terminals, and an upper housing 117 for fixing the upper terminals and the upper shielding plate together. Firstly, fixing an upper shield plate 114 to an upper inner insulator 116 through an injection molding mode to form an upper half component 119, and then assembling two rows of upper terminals 112 to two sides of the upper inner insulator 116; alternatively, one row of upper terminals and the upper shield plate are first co-molded into the upper inner insulator 116, and then the other row of terminals is assembled to the upper inner insulator. Then, the upper outer insulator 118 is further injection molded on the upper inner insulator 116 and the two rows of upper terminals 112, so as to form the terminal module 110, and the upper inner insulator 116 and the upper outer insulator 118 together form the upper housing 117. Of course, the method is not limited to the above method, and the two upper sub-terminal modules may be formed separately and then assembled with the shielding plate interposed therebetween. The lower terminal module 210 also includes two rows of lower terminals 212, a lower shielding plate 214 located between the two rows of lower terminals, and a lower seat 217 for fixing the lower terminals and the shielding plate, and as shown in fig. 13-14, the lower inner insulator 216 and the lower outer insulator 218 of the lower terminal module 210 together form the lower seat 217. It is manufactured in a manner similar to that of top terminal module 110, either as described above, or otherwise. That is, from a technical point of view, the upper inter-insulator 116 and the upper inter-insulator 118 together form the upper seat body 117. The lower inter-insulator 216 and the lower inter-insulator 218 together form a lower seat 217. The complete structure of the upper terminal module 110 and the lower terminal module 210 can be seen in fig. 6-10.

Note that the upper housing 117 includes an upper base 1171 and an upper tongue 1172 extending forward from the upper base 1171. Similarly, the lower seat 217 includes a lower base 2171 and a lower tongue 2172 extending forward from the lower base 2171. The upper terminal 112 includes horizontal contact portions 1121 arranged on the front and back sides of the upper tongue 1172. The lower contact 212 includes a horizontal contact portion 2121 arranged on the front and back sides of the lower tongue 2172, and a pin 2122 extending from the lower surface of the lower base 2171 for soldering to a circuit board. The upper terminal 112 is higher and includes a pin 1122 and a vertical portion 1123 for connecting the pin, and it can be seen that the upper terminal module 210 further includes a set of insulating blocks 120, the insulating blocks 120 are fixed on the vertical portion 1123 of the upper terminal 112 for fixing the longer pin of the upper terminal to avoid shaking. An insulating block 120 is fixed to the vertical portion 1123 adjacent to the pins 1122, while fixing the upper terminals of the two rows. The other two insulating blocks 120 fix the vertical portions 1123 of the upper terminals in a row, respectively, substantially at the middle of the vertical portions 1123 in the height direction.

The upper metal shell 130 includes an upper tubular portion 132 and an upper rear plate 134, the upper tubular portion 132 surrounds the upper tongue portion 1172 to form an upper mating opening 133, and the upper rear plate 134 is bent downward and extends behind the vertical portion 1123 of the upper terminal 112. Similarly, the lower metal shell 230 includes a lower tubular portion 232 and a lower rear plate 234, the lower tubular portion 232 surrounding the lower tongue plate 2172 to form a lower mating opening 233, and the lower rear plate 234 being located behind the vertical portion of the lower terminal 212 or the rear end surface of the housing, but in front of the vertical portion of the upper terminal 112.

The upper housing 117 further integrally forms a support 1173 that is located between the upper interface 133 and the lower interface 233, as shown in fig. 3, and is adjacent to the lower housing 217, as viewed from the front to the back. A butt joint structure in the vertical direction is formed between the upper seat body 117 and the lower seat body 217. In this embodiment, the docking structure includes a plurality of protruding portions 1175 located on the bottom surface of the supporting portion 1173 and a plurality of recessed holes 2174 located on the upper surface of the lower base 217, and the protruding portions 1175 are received in the corresponding recessed holes 2174 one by one. In this embodiment, the lower metal shell 230 is formed with a plurality of through holes 235, and the through holes 235 are vertically aligned with the recessed holes 2174 one by one, so that the projections 1175 can be allowed to pass through the through holes 235 and enter the recessed holes 2174. In this embodiment, the supporting portion 1173 is integrally formed with the upper housing 117, and of course, such a supporting portion 1173 can be formed on the lower housing 217 or on both the upper and lower housings, as long as it can enhance and stabilize the whole stacked connector.

It will be appreciated that the upper metal shell 130 of the upper connector 100 is secured to the upper housing 117 by conventional means. The upper metal shell 130 is provided with a plurality of front tabs 136 and rear tabs 137, and the front tabs 136 and the rear tabs 137 are clamped together at a part of the upper base 117 in the front-rear direction, so that the upper metal shell 130 is fixed on the upper base. The rear tabs of the lower metal shell 230 are omitted, which allows the protruding portion 1175 of the supporting portion to be combined with the lower metal shell 230 and the lower housing 217, and also to be combined with the lower metal shell 230. It will be appreciated that the support 1173 occupies the space between the upper and lower mating ports when viewed from the front to the rear, which not only strengthens the overall connector, but also simplifies assembly of the connector. In the stacked connector, the vertical portion of the upper terminal is longer and is easily interfered by external noise, the upper metal shell 130 of the stacked connector has more covers to better ensure the electrical performance of the upper terminal 120, and the supporting portion 1173 is integrally formed on the upper base body 117 and can be integrally formed with the upper base body, so that the plastic molding of the upper base body is simple, the assembly of the two connectors is also simple, and the strength of the stacked connector 10 is ensured. As can be seen in fig. 4, the support 1173 is located behind the upper and lower mating ports or tongues in the front-to-back direction, and the support 1173 is to ensure the overall strength of the connector in this configuration.

The upper metal case 130 further includes a pair of side plates 131 formed by extending forward from both side edges of the upper rear plate 134 for shielding the vertical portions of the upper terminals 112 in the lateral direction, and a pair of elastic fingers 138 electrically and mechanically connected to the lower metal case 230 for achieving a better grounding and shielding function. Fig. 17 shows another embodiment of the upper metal shell 130, an additional front plate 139 is formed extending downward from the lower rear edge of the upper tubular portion 131, and the front plate 139 abuts downward against the upper side wall of the lower tubular portion 232 between the upper and lower pairs of openings to shield the vertical portion 1123 of the upper terminal.
