Definitions

  • This invention relates to an electrical connector, and in particular an electrical connector for short- circuiting a pair of pins mounted on a printed circuit board.
  • a general object of this invention is to provide a compact connector of a low height or profile which ensures a firm, stable and better contact with an adjacent pair of conductive pins with adequate holding pressure and proper balance.
  • a connector for electrically connecting a pair of parallel conductive pins to one another comprising:
  • the holding portions act like cantilevered springs and project laterally of the pins.
  • the connector can have a height shorter than the pin length.
  • the connector can be conveniently fitted into an insulation housing to form an assembly. Normally, the pins themselves would be mounted as a header on a printed circuit board.
  • the holding portions normally lie in the same plane parallel to the main base plate and may be rectilinear strips. In another arrangement, the holding portions are cranked to possess regions located at different levels or heights. Inter alia, this modifies the position of the contact zones. Additional end portions which act as supports can be disposed opposite the connector portions and connect solely with the plate. These support portions may abut or lie near the displaceable distal end regions of the holding portions. In this manner, two U-shaped contact units, one superimposed on the other, in inverted fashion are created.
  • contact zones are provided on the plate to cooperate with those on the holding portions.
  • the contact zones may be at the same or different levels.
  • a pin header 50 and an associated connector 60 serve to interconnect a pair of pins to modify a circuit on a printed circuit board.
  • the pin header 50 comprises a sheet-like body made of an insulating material carrying a plurality of parallel metal conductive pins. The pins vertically penetrate the header body and are fixed thereto. The lower ends of the pins which project downwardly from the header body are inserted in through holes in the printed circuit board (not shown) and soldered to the board. A pair of adjacent pins can be short-circuited by locating the connector 60 on the upper ends of these pins.
  • the connector 60 itself is a metal component composed of a base section 61 and two pairs of resilient strip sections 62a, 62b; 63a, 63b which extend from the base section 61.
  • the strip sections 62a,62b; 63a, 63b have outwardly directed lips for guiding the pins therebetween.
  • the strip sections 62a, 62b; 63a,63b act as leaf springs and hold two adjacent pins in the longitudinal direction to electrically interconnect the pins, i.e. as a short-circuit.
  • the connector is not particularly compact.
  • the height (h) is especially a problem since the resiliency of the strip sections 62a,62b; 63a,63b as leaf springs depends on their length ( ). If the length ( ) is made shorter to decrease the height, the sections 62a, 62b; 63a,63b cannot provide a stable holding force.
  • a connector assembly has a connector component 10 held in a housing 30 and is located on a pair of pins 42,43 of a header 40.
  • the pin header 40 is again composed of a sheet-like body 41 made of an insulating material carrying a plurality of parallel metal conductive pins (42,43).
  • the pins vertically penetrate the header body 41 and are fixed to the body 41.
  • the lower ends of the pins which extend below the header body, are inserted in through holes in a printed circuit board (not shown) and are soldered to the board.
  • Figures 3 to 6 show the connector component 10 which is made of a conductive material, such as a metal and had a generally rectangular hollow configuration.
  • the component part 10 has a rigid base plate 11 serving as a main body portion extending between a pair of side edges A and B spaced apart in the direction C and first and second respective holding portions 13,18 opposite the plate 11.
  • the holding portions 13,18 extend in the direction C and are spaced from each other in a direction D substantially perpendicular to the direction C, to permit the conductive pins 42,43 to be inserted between the plate 11 and the portions 13,18.
  • An end portion 12 connects an end region 132 of the holding portion 13 to the side edge A of the plate 11 and end portion 17 connects an end portion 182 of the holding portion 18 to the edge side B of the plate 11.
  • the dimensions of the respective end portions 16,21 12,17 are such that the holding portions 13 and 18 are located in the same plane and the distance between the holding portions 13 and 18 and the plate 11 remains uniform along the entire length of the portions 13 and 18.
  • the plate 11, together with the portions 12 and 13 constitute a first U-shaped contact unit while the plate 11, together with the portions 17 and 18 constitute a second U-shaped contact unit inverted in relation to the superimposed first unit.
  • the connector component 10 with its constituent portions 11,12 17,13,18,16,21 as described is formed in one piece by bending a single conductive metal blank a number of times.
  • the pins 42,43 located in the rectangular cavity defined by the portions, 11, 12, 13, 16, 18, 17,21 with the pin 42 disposed between the plate portion 11 and the end region 131 of the holding portion 13 and gripped ' by the projections 14 and 15 and the pin 43 disposed between the plate portion 11 and the end region 181 of the holding portion 18 and, gripped by the projections 19 and 20. In this way, the pins 42 and 43 are reliably electrically connected via the component 10.
  • the holding portions 13 and 18 have a height (h) ( Figure 2) less than the conventional counterpart of Figure 1 and a length ( ) ( Figure 2) longer than the length of the conventional counterpart of Figure 1.
  • FIG. 7 shows the component 10 with the associated housing 30 in which the component 10 is fitted as indicated by arrow E.
  • the housing 30 is made of an insulating material, such as plastics and is of generally rectangular hollow box-like configuration.
  • the housing 30 has a bottom wall 31 adjoining four surrounding side walls defining an opening therebetween.
  • Two through holes 32 and 33 are provided in the bottom wall 31 of the housing 30 to provide access for the pins 42,43.
  • a recess or window 35 is formed in one of the longer side walls 34 to confront the plate 11 and more particularly the projection 22 thereof.
  • Figures 8 to 9 depicts another assembly constructed in accordance with the invention wherein like reference numerals denote like parts to Figures 2 to 7.
  • the holding portions 13, 18 of the connector component 10 are non- rectilinear. More particularly as shown in Figure 9, the portion 13 is cranked at about its center to project downwards from a region aligned with the top of the plae 11 and the portion 18 is cranked to about its center to project upwardly from a region aligned with the bottom of the plate 11.
  • the projections 14,19 are formed on end regions of the portions 13 and 18 are located at the same level, while the complementary projections 15 and 20 are also likewise aligned and disposed opposite to the projections 14 and 19 so that all the projections 14, 15, i9, 20 are at the same level.
  • the supportive portion 12 is disposed at a higher level than the level of the projections 14,19,15,20, and the portion 17 is disposed at a lower level than the projection level.
  • the modified form of connector component 10 can be fitted to the pins 42,43 with an improved balance and stability.
  • the end portions 12,17, 16,21 are flat and perpendicular to the main plate portion 11 but this is not essential and these portions may have, for example, a curved profile.
