Definitions
- the present invention relates to a stacked electrical connector and more particularly to a stacked, shielded I/O connector having improved means for aligning the solder tail portions of the connector.
- This connector assembly is made from an increased number of parts (i.e. the number of parts of a single connector multiplied by the number of connectors laid on each other).
- the assembling of this type of connector not only requires extra parts, such as joint pieces. Because of the increased number of parts in such a connector, but is also tedious and the cost of assembly increases accordingly.
- one object of the present invention is to provide a multi-pole electric connector which can be assembled using the least possible number of parts to facilitate the assembly of the connector parts.
- an electrical connector comprises: a casing having a plurality of connector components on its front for mating to opposing connector components of a counter-connector, the housing having a plurality of conductive terminals press-fitted therein with their contact portions arranged in each connector component, and a shell covering the front of the housing having a corresponding number of shielding enclosures each closely surrounding each of said connector components.
- the number of the connector components can be determined to meet occasional demands.
- the housing has two connector components arranged at upper and lower levels. This arrangement is advantageous to the reducing of the bottom size of the connector assembly to a minimum.
- Each terminal of the connector may have an L-shape with a contact portion on one end and a solder tail portion on the other end.
- the solder tail portions extend down on the rear side of the housing when the terminals are press-fitted along the rear side of the housing into place within the appropriate connector component.
- the shell may have pegs on its bottom for fastening the electric connector to a printed circuit board.
- the electrical connector assembly may further comprise latch members and the shell may have slots on the opposite sides of each connector component, and the housing may have slots aligned with the slots of the shell, thereby fastening the latch members to the housings when the latch members are inserted in and caught by the slots of the housing.
- a stacked two-layer perpendicular, or right angle, connector assembly is illustrated generally as 1 and is seen to comprise a housing 2 molded from a suitable dielectric resin and a metal shell 3 covering the front portion 4 of the housing 2.
- the housing 2 has upper and lower fitting protrusions, or connector components, shown as receptacle connectors 5 on its front for mating with corresponding opposing male, or plug connectors of a counter-connector assembly (not shown).
- the housing 2 illustrated further has two vertical walls 60 that extend rearwardly from the front portion 4 thereof. As explained below, these walls 60 provide support for a terminal solder tail portion alignment means as well as define a channel which partially encloses the solder tail portions of the terminals 7.
- the housing 2 may further include lateral walls 63 that also extend rearwardly along the sidewalls 60 at an angle thereto in order to provide a sufficient amount of stiffness to the entire housing 2.
- a plurality of electrically conductive terminals 7 are press-fit into the connector portions 5 from the rear side of the housing 2. Their contact portions 8 are laterally arranged and held within each connector portion 5.
- a metal shell 3 is fastened to the housing 2, as described in greater detail below.
- the shell 3 has two enclosures 11 formed on the upper and lower sides of a central, rectangular opening 10 of a metal plate 9 that is coextensive with the front 4 of the housing 2 when applied thereto. These enclosures 11 are aligned with the housing 2 and closely surround the connector portions 5 of the housing 2 when applied to the housing 2 so that they, in effect, serve as a shield for the receptacle connectors 5.
- the shielding shell 3 has an upper engagement strip 15 which engages the upper edge of the metal plate 9, extending rearward at right angle relative to the front 4 of the housing 2. It further has two lower engagement extensions 17 that engage the lower edge of the metal plate 9, by extending rearwardly at an acute angle somewhat less than the right angle relative to the front in the offset manner illustrated in FIG. 4. Each lower engagement extension 17 ends with a depending peg or engagement arm 18.
- the metal plate 9 further has two engagement tabs 19 extending rearwardly from the centers of its opposite sides at right angles relative to the front 4 of the housing.
- Each tab 19 has an opening 20 formed therein which engages by a protrusion 21 formed on either side of the housing 2.
- each terminal 7 of the connector 1 has an L-shape with a contact portion 8 disposed on one end thereof and a solder tail portion 22 disposed on its other end.
- the solder tail portions 22 extend down along the rear side of the housing 2 and extend below the bottom 16 of the housing 2 when the terminals 7 are press-fitted from the rear side of the housing 2 and therefore, the solder tail portions 22 may be considered as angularly diverging from the contact portions 8 and their respective connector portions 5.
- the connector housing 2 is provided with upper and lower terminal guide plates 23 and 24 that accommodate the multiple rows of terminal solder tail portions, four such rows of solder tail portions being shown in FIG. 1 as entering the upper guide plate 23 and eight such rows being shown as entering the lower guide plate 24.
- the upper guide plate 23 contains a plurality of insertion holes 50 that receive and hold upper portions of the solder tail portions 22 of the terminals 7 that are inserted in the upper receptacle connector 5 which the lower guide plate 24 has a plurality of insertion holes 51 that receive and hold the solder tail portions 22 of the terminals 7 inserted in both the upper and lower portions receptacle connectors 5 so that the solder tail portions 22 of all the terminals 7 are put in correct alignment with opposing holes on a printed circuit board 70.
- the solder tail portions 22 of the terminals 7 are maintained in alignment by the insertion openings 50, 51 which are arranged in multiple rows of openings and in which adjacent rows are staggered with respect to each other. Because the number of connector contacts are the same for each connector portion 5, the lower guide plate 24 contains twice as many insertion openings 50 as the upper guide plate 23.
- FIG. 8 shows the lower guide plate 24 as having insertion holes 51 staggered at regular intervals.
- the upper guide plate 23 has a similar pattern of insertion holes 50 for holding the solder tail portion of terminals, which are inserted in the upper receptacle connector 5.
- Both of the alignment or guide plates 23, 24, because of their vertical separation, cooperate to keep the solder tail portions of the terminals 7 separate which also serves to prevent potential shorting when the solder tail portions are at small pitches (i.e. the spacing between adjoining and adjacent solder tail portions).
- the present invention is therefore beneficial in the production of high circuit density stacked I/O connector.
- the guide plates 23, 24 may include ramped entryways 65 disposed around their respective insertion holes 50, 51.
- the connector assembly 1 further includes latch members 26 that extend forwardly from the front 4 of the connector 1 to engage with similar latch members of the counter connector.
- Each latch member 26 comprises a bifurcated arm 29 with an associated engagement hook 30.
- the shielding shell 3 has latch slots 53 on the opposite sides of each fitting protrusion 11, and the housing 2 has slots 54 formed therein and aligned with the latch slots 53 of the shell 3.
- each latch piece 26 can be fastened to the housing 2 when its bifurcated arms 29 are inserted in and caught by the associated slot 54 of the housing 2.
- contact portions 8 of one set of terminals 7 are press-fitted into the holes of the housing 2 at the lower receptacle connector 5, and the contact portions 8 of another set of terminals 7 are press-fitted into the holes of the housing 2 at the upper receptacle connector 5.
- the tails 22 of the lower set of terminals are then bent 90° to the contact portions 8. Then the tails 22 of the upper set of terminals are similarly bent.
- the upper guide plate 23 is slid onto the tails of the upper set and attached to the housing 2 to hold the solder tail portions 22 of the terminals 7, and then the lower guide plate 24 is slid onto all of the tails and attached to the housing 2 to hold the solder portions tail 22 of all of the terminals 7.
- the attachment of the guide plates 23, 24 is accomplished by an interference fit or the like. As shown in the preferred embodiment, especially in FIG. 1, the guide plates 23, 24 engage the housing walls 60 at recesses 61 formed therein.
- the shielding shell 3 is then applied to the front 4 of the housing 2, and is fastened thereto with latch means. Specifically, the shield portions 11 that enclose the upper and lower receptacle connectors 5 of the housing 2, and its engagement tabs 19 are caught by the protrusions 21 formed on the opposite sides of the housing 2. Finally, the bifurcated arms 29 of the latch pieces 26 are inserted in the latch slots 53 of the shell 3 and the associated slots 54 of the housing 2.
