Definitions

  • the present invention relates generally to surface mount connectors mounted by soldering, to printed circuit boards, and more particularly to a surface mount connector having a terminal structure with an improved pitch arrangement of the connector solder tails.
  • Conventional surface mount connectors use insulative housing with a plurality of terminals.
  • the terminals have contact portions on ends thereof that line a slot formed in the connector housing.
  • Solder tail portions are formed on the other ends of the terminals and extend on both sides of the connector housing.
  • the solder tail portions are arranged substantially flush with the bottom surface of the connector housing so as to contact conductive pads on the circuit board.
  • increasing the number of contact portions of the terminals causes a corresponding reduction in the pitch of the solder tails and of the contact portions of the terminals. This occurs when the overall size of the connector is reduced.
  • the present invention is directed to a surface mount connector that overcomes the aforementioned disadvantages.
  • Another object of the present invention is to provide a surface mount connector wherein the pitch of the terminal solder tail portions is decreased while the number of terminal contact portions is increased and wherein the terminal contact portions are provided at a greater pitch than that of the solder tail portions.
  • a surface mount connector having an insulative connector housing and a plurality of terminals disposed in the connector housing, the terminals having contact portions formed along one set of ends thereof, the contact portion being arranged in parallel along a slot formed in the connector housing in a predetermined pitch.
  • the terminals of each solder tail portion extend out of the connector housing along only one side of the connector, but in a parallel arrangement having a pitch equal to one-half the pitch of the contact portions.
  • the solder tail portions extend substantially flush along a bottom surface of the connector housing and extend outwardly therefrom.
  • a surface mount connector in accordance with another principal aspect of the present invention, includes an elongated connector housing formed from an electrically insulative material and a plurality of conductive terminals loaded in the connector housing on opposite sides of an opposing connector-receiving passage, the terminals including contact portions that face inwardly of an opposing connector engaging slot formed in the connector housing.
  • the terminals also include solder tail portions for attaching the connector to the surface of a printed circuit board by way of soldering, the solder tail portions extending outwardly from the connector housing along a bottom surface thereof.
  • the terminals in the connector are arranged so that the contact portions of each pair of terminals lie in opposing alignment with each other.
  • the terminals are configured such that the solder tails of one of the terminals in a chosen pair of opposing terminals extending out of the connector housing along a bottom surface thereof, while the solder tails of the other terminal in the chosen pair of terminals extend under the one terminals, with both of the two solder tail portion arranged in a parallel relationship. In this manner the solder tails of the terminals on both sides of the passage, but extend out of the connector on only one side of the connector.
  • the contact portions of the terminals are arranged in a predetermined pitch, and the solder tail portions are arranged in a pitch that is one-half of the predetermined pitch.
  • the connector housing may be formed as a receptacle connector housing having two parallel slots, or receptacles that engage portions of an opposing connector.
  • the terminal contact portions of the two rows of terminals line opposite sides of each slot.
  • the solder tail portions of the terminals lining the sides of one of the two slots extend outwardly along only one side of the connector housing, while the solder tail portions of the terminals lining the sides of the other of the two slots extend outwardly along the other side of the connector housing.
  • the terminal contact portions are provided with a predetermined pitch that is twice the pitch of the terminal solder tail portions.
  • the pitch between the adjacent terminal contact portions is relatively wide, and shorting between adjacent terminal contact portions can be successfully avoided in order to ensure a secure electrical connection between the connector and an opposing connector.
  • the pitch between adjacent solder tail portions may be made relatively narrower, thereby increasing the density for connecting of circuits on a printed circuit board. The solder tail portions extended outwardly from the bottom surface of the connector housing, and thus inspection of the soldering of the solder tail portions to the circuit board contact pads may be performed without interference of the connector housing.
  • FIG. 1 is a perspective view of a surface mount connector assembly, generally indicated at 1 that includes a preferred embodiment of a surface mount connector 5 constructed in accordance with the principles of the present invention.
  • the surface mount connectors of the present invention are particularly suitable for providing a connection between circuits on a circuit board 2 and a series of wires enclosed in a cable 3 and terminated to a wire connector, such as the I/O style connector 4 illustrated.
  • An intervening right-angle connector 6 is mated to the surface mount connector 5 to provide a connector having a dual row leaf terminal arrangement that is matable with the I/O-type cable connector 4.
  • the surface mount connector assembly 1 includes the surface mount connector 5 mounted to a surface of the printed circuit board 2 and an engaging, right-angle connector 6 that engages with the upper portion of the surface connector 5.
  • the surface mount connector 5 can be seen to include a connector housing 7 formed from an electrically insulative material and a plurality of conductive terminals 8 that are mounted in the connector housing 7 at a predetermined pitch P .

  • the terminals 8 are mounted in the connector housing 2 longitudinally in a predetermined pitch P with respective contact portions 10 of the terminals mutually opposing each other on opposite sides of the slots 9.
  • Figure 2. The terminals 8 are arranged in two rows having aligned terminals, as shown in Figure 4. Two sets of terminals 8 are shown in FIGS. 2 and 3 as mounted in two distinct rows 64a, 65a and 64b, 65b in each slot 9. It can be seen that the terminals 8 each have solder tail portions 11 that project along the bottom surface of the connector housing 7 in a manner such that they lie substantially flush with the connector housing bottom surface.
  • solder tail portions 11 of the two rows of terminals 8 arranged in one slot 9 project out from one side of the connector housing, while the solder tail portions 11 of the rows of terminals 8 of the other slot 9 project out from the other and opposite side of the connector housing 7.
  • each such terminal can be seen to include a terminal body portion 12, a pair of contact portions 13a, 13b, and an associated solder tail portion 11.
  • the solder tails 11 of the respective terminals 8 has approximately half width of that of a corresponding opposing terminal body portion 12, such that the solder tails 11 of one row of terminals 8 in one slot 9 extend out of the connector housing 7, but underneath the terminal body portion 12 of the respective terminals 8 of the other row of terminals disposed in the same slot 9, This passing is facilitated by way of a recess, or cavity, 62 formed in the rightmost terminal body portion 12.
  • the pitch of the solder tails 11 is one-half that of the pitch P of the terminals 8, i.e., 1 ⁇ 2-P .
  • the contact portions 10 of the terminals 8 are formed in a characteristic configuration and they each include two divided contact portions 10a, 10b that preferably extend parallel to each other.
  • One of the divided contact portions 10a is longer than the other of the two divided contact portions 10b, so that arc-shaped contact portions 13a, 13b that are provided at the distal ends of the respective divided contact portions 10a, 10b are aligned along the longitudinal direction of the contact portion 10, i.e, vertically.
  • these contact portions 13a, 13b protrude slightly into the connector housing engagement slots 9.
  • the surface mount connector 5 In assembling the surface mount connector assembly 1, to the edge portion of the printed circuit board 2, the surface mount connector 5 is first mounted to the surface of the circuit board 2, near an edge portion of the circuit board 2 as shown near side of Figure 1.
  • the solder tail portions 11 of the connector 5 project outwardly from the connector housing 7 along the sides of the connector housing 7 (or what may be considered as forward and rearward when viewing Figure 1) .
  • the solder tail portions 11 are aligned in opposition to conductive pads (not shown) formed on the surface of the circuit board 2.
  • the solder tail portions 11 and the conductive pads are then surface soldered by any desirable manner of soldering, such as by reflow soldering, in order to fix the connector 5 to the circuit board 2.
  • the pitch of the solder tail portions 11 is one-half of the pitch P of the terminal contact portions 10, and thereby reduces the area occupied by the connector 5 and its solder tail portions 11. Thus, a high density connection may be achieved with the circuit board 2 while using a reduced amount of space thereon.
  • the surface mount connector 5 is of simple construction which basically includes the connector housing 7 and the plurality of conductive terminals 8 set forth above.
  • the solder tails 11 are also formed in a simple exterior configuration, in that they extend outwardly along the bottom surface of the connector housing 7 exterior of the connector housing 7. This structure prevents the solder tail portions 11 from being extremely longer, and facilitates the manufacturing of the solder tail portions 11 of the terminals 8. It is also easy to maintain the arrangement pitch of the solder tails 11 in correspondence with a predetermined pitch P , and enable the surface soldering of the solder tail portions 11 to the circuit board 2 by a normal soldering reflow method.
  • solder tail portions 11 project on two opposing sides of the connector housing 7, so that the solder tail portions 11 and the circuit board contact pads of the circuit board lie exposed exterior of the connector housing 7.
  • the right-angle connector 6 is provided as part of the overall surface mount assembly 1 in order to provide an intervening connection, or an intermediate connector between the surface mount connector 5 and a counterpart cable connector that encloses a plurality of terminated wires, such as is the case with input/output ("I/O") style connectors.
  • This right-angle, intermediate connector 6 engages on the upper portion of the surface mount connector 5 and includes a pair of plug portions 60 that are disposed within a housing engagement portion 14 that has an interior cavity 61 that is dimensioned to receive substantially the entire connector housing 7 of the surface mount connector 5 therewithin so that a bottom surface 5a of the housing body 16 of the intermediate connector 6 will substantially abut the circuit board 2 as shown in FIGS. 5 and 6.

  • This leaf portion 15 receives and supports the contact portions 19 of a plurality of conductive terminals 17 and provides surfaces for the support and arrangement of the terminals 17 in two distinct sets of terminals, wherein each set has two opposing rows of terminals 19.
  • the terminals 17 of the intermediate connector 6 are mounted with the same arrangement pitch P as the contact portions 10 of the surface mount connector terminals 8, and form likewise two sets of terminals corresponding to the two rows of terminals 8 in the two engagement slots 9 of the surface mount connector 5.
  • Contact portions 18 are provided at ends of the terminals 17 which extend a sufficient distance to project into the first engagement portion 14 and the cavity 61 located along the bottom surface 16a of the connector housing body 16. In this regard, the contact portions 18 project into respective engagement slots 9 of the surface mount connector 5 and electrically contact and engage opposing contact portions 10 of the connector terminals 8.
  • Second contact portions 19 are provided at the other end of the intermediate connector terminals 17 and are is formed into their specific configuration by turning them back upon themselves within the engagement portion 15 as shown in FIGS. 5 & 7. These contact portions are provided so as to oppose each other in pairs near the engagement end 15 of the intermediate connector 6.
  • the housing body 16 of the intermediate connector 6 includes end blocks 20 provided at the opposite ends thereof as shown in FIGS. 1 and 6 and provide a means for mounting the intermediate connectors 6 to the circuit board 2.
  • These end blocks 20 each include, as shown, screw holes 21 passing therethrough in a vertical direction.
  • Each end block has a connector guide pin 22 that faces to the front of the connector housing 16.
  • These guide pins are positioned on opposite sides of the connector housing 16 and are provided for guiding the engagement of the opposing cable connector 4 into engagement with the intermediate connector 6.
  • the guide pins 22 may include, as shown in Figure 6, a round shaft 24 integrally connected to the distal plug end 26 of the shaft 24 by way of a thin neck portion 25.
  • the plug ends 26 may differ in size, with one plug end 26b being larger than the other plug end 26a to provide a polarizing feature to ensure proper orientation of the cable connector 4 with the intermediate connector 16 and the plug ends may differ in their axial extent, with one being longer than the other.
  • the right-angle connector 6 is fixed on the circuit board 2 by first engaging it with the upper portion of the surface mount connector 5 in order to complete the surface mount connector assembly 1.
  • One manner of fixing these intermediate connectors 6 to the surface mount connectors 5 and the circuit board is shown in the middle of Figure 1.
  • the intermediate connectors 6 are engaged with two corresponding surface mount connectors 5 in a manner such that the whole connector housings 7 of the connectors 5 are received within the first engagement portion 14 of the intermediate connector housing 16.
