Background
Connectors for printed circuit boards, particularly PIP connectors, typically have a plurality of pins forming an array. When connecting or soldering such a connector to a printed circuit board, the array of pins on the connector needs to be precisely aligned with the corresponding array of holes on the printed circuit board so that when the connector is placed on the printed circuit board, the pins on the connector can be precisely placed into the corresponding holes for soldering.
In order to accurately align the pin array of the connector with the corresponding hole array on the printed circuit board, attempts have been made to use a pin alignment plate. The positioning plate is formed separately from the connector housing and is connected to the connector housing. The alignment plate has an array of holes therein arranged substantially the same as the array of holes in the printed circuit board, and each pin of the array of pins of the connector protrudes through a corresponding hole in the array of holes in the alignment plate. Thus, the connector pins protruding through the hole array of the alignment plate are properly aligned with the hole array on the printed circuit board. Thus, when the connector is placed on a printed circuit board, each pin on the connector can be accurately placed into a corresponding hole.

As shown, the connector 100 includes a connector housing 110, a middle partition wall 112 of the connector housing 110 and an outer housing of the connector housing 110 defining a receiving cavity 114 at a rear of the connector housing 110, the receiving cavity 114 for receiving a wiring plug (not shown). The connector 100 also includes a locating plate 120 integrally formed with the connector housing 110. In the preferred embodiment shown in the drawings, the positioning plate 120 is integrally formed with the bottom plate 116 of the connector housing 110.
As shown, the connector 100 includes a pin array disposed in the connector housing 110, including 3 rows of pins 130, 132, 134 disposed at low and high positions, respectively, i.e., a lower row of 4 pins 130, a middle row of 4 pins 132, and an upper row of 4 pins 134, for a total of 12 pins. Each pin 130, 132, 134 includes a pin first section 130a, 132a, 134a (also referred to as a terminal-side end) within the receiving cavity 114 for electrical communication with a conductor in the terminal plug upon insertion of the terminal plug into the receiving cavity 114. Each pin also includes a pin second section 130b, 132b, 134b extending from the pin first section 130a, 132a, 134a through the intermediate spacer wall 112 to proximate the alignment plate 120, a pin third section 130c, 132c, 134c extending from the pin second section 130b, 132b, 134b through the alignment plate 120, and a pin fourth section 130d, 132d, 134d at the plate-side end of the pin. As shown, each of the first leg sections 130a, 132a, 134a extends substantially horizontally, and each of the second leg sections 130b, 132b, 134b bends downward after passing through the middle partition wall 112 to extend toward the alignment plate 120 in a substantially vertical direction. As best seen in fig. 11, the upper row of pins 134 is bent downwardly a greater distance from the middle partition 112, the middle row of pins 132 is bent downwardly a middle distance, and the lower row of pins 130 is bent downwardly a shorter distance from the middle partition 112 to align with corresponding holes in the alignment plate 120.
As shown, for example, and as best shown in FIG. 7, the first leg of each pin is substantially identical in cross-section and is in the form of a flattened rectangle. The cross-section of the upper row of pins 134 remains substantially constant from the first pin section 134a to the third pin section 134 c. The cross-section of the middle row of pins 132 remains substantially constant from the first pin section 132a to the second pin section 132b, and the width of the cross-section decreases at the third pin section 132 c. The cross section of the lower row of pins 130 remains substantially constant from the first leg 130a to the second leg 130b, and the width of the cross section at the third leg 130c becomes smaller and smaller than the width of the third leg 132 c. The fourth sections 130a, 130b, 130c, 130d of the pins of each row of pins have a reduced cross-sectional width and are generally square for insertion into corresponding holes in the printed circuit board.
During assembly, the third pin sections 130c of the four lower rows of pins 130 are respectively inserted into the first slot sections 122a of the corresponding slots 122 and are respectively abutted against the bottoms of the first slot sections 122 a. The third leg sections 132c of the four middle row of legs 132 enter the second slot sections 122b of the corresponding slots 122 and abut against the shoulders between the first slot sections 122a and the second slot sections 122b, respectively. The third leg sections 134c of the four upper rows of legs 134 are then each received in the third slot section 122c of the corresponding slot 122 and are each abutted against a shoulder between the second slot section 122b and the third slot section 122 c. Thus, the four lower rows of pins 130 are positioned with the third leg portions 130c abutting the bottom of the first slot segments 122a of the four slots 122, respectively, the four middle rows of pins 132 are positioned with the third leg portions 132c abutting the shoulders between the first and second slot segments 122a, 122b of the four slots 122, respectively, and the four upper rows of pins 134 are positioned with the third leg portions 134c abutting the shoulders between the second and third slot segments 122b, 122c of the four slots 122, respectively. In addition, the positions of the groove bottom and shoulder of each groove on the positioning plate also correspond precisely to the positions of the hole arrays on the printed circuit board. Thus, the precise positioning of all 12 pins of the pin array of the connector 100 is achieved, and each pin on the connector 100 can be precisely placed into a corresponding hole on the printed circuit board 20 when the connector 100 is placed on the printed circuit board 20.
