- FIG. 6 An example of a conventional telephone is shown in FIG. 6.
- the telephone includes a base housing 3 and a cover housing 4 to be mated with the base housing 3.
- One printed circuit board 2 is mounted in parallel with a horizontal bottom surface of the base housing 3 while the other printed circuit board 1 is mounted in parallel with a sloped top surface of the cover housing 4.
- Both printed circuit boards 1, 2 are interconnected by way of wire harness.
- a male connector 5 is connected to the printed circuit board 2 by soldering.
- a connector 7 at one end of the wire harness 6 is soldered to the other printed circuit board 1.
- a female receptacle-type connector 8 at the other end is removably connected to a male type connector 5.
- the connector 8 is first connected to the connector 5 and then the cover housing 4 is mated with the base housing 3, thereby requiring at least two connection steps. Such steps, especially the mating the connectors 5, 8 is difficult and time consuming especially because of the generally minimum length of the wire harness 6.
- the first housing includes a contact section and a tine or post section; the contact section is secured in the first housing which is positioned in a cavity in the second housing, and the post section extends outwardly from the first housing.
- the second housing has a contact section secured in the cavity of the second housing and slidably engages the contact section of the first contact with a tine or post section extending outwardly from the second housing.
- the post sections of the first and second contacts are generally soldered to through holes in the printed circuit boards.
- the second housing having the second contact secured therein is allowed to pivotally move within a certain angle with respect to the first housing having the first contact secured therein while maintaining electrical connection between the first and second contacts.
- FIG. 1 is a perspective view of an embodiment of the connector according to this invention shown in the mated condition.
- FIG. 2 is a vertical cross-sectional view of FIG. 1.
- FIG. 3 is an exploded perspective view of the connector.
- FIG. 4 is a cross-sectional view of the first housing.
- FIG. 5 is a cross-sectional view of the first housing in a slanted position from the vertical position relative to the second housing as shown in FIG. 4.
- FIG. 6 is a simplified view to show a simplified construction of a conventional telephone set with the base housing separated from the cover housing.
- the connector 10 includes an outer housing 11 and an inner housing 12 to be mated in the outer housing 11.
- These housings 11, 12 are made from a suitable electrical insulation material, for example, plastic.
- the outer housing 11 comprises end walls 14 extending vertically from a bottom wall 13 and sidewalls 15, 15' extending vertically from the bottom wall 13, walls 14, 15, 15' being 5 orthogonal to each other. Slots 16 are formed in the walls 14, each of the slots 16 comprising tapered sections 16a, vertical sections 16b, and an arcuate bearing section 16c.
- the right and left sidewalls 15, 15' have tapered inner walls 15a, 15a' with wider spacing toward the top
- edges 15b of triangle-shaped ribs 15b extend along the inner tapered surface 15a of the side wall 15 at a certain pitch (see FIG. 3.).
- the inner surface 15a of the sidewall 15' is formed similar to the sidewall 15, thereby providing opposite edges of
- ⁇ j _5 triangle-shaped ribs on both sidewalls are formed at the top of the sidewall 15'.
- the inner surface 13a of the bottom wall 13 is arcuate.
- a plurality of tab contacts 18 are disposed in retaining holes 19 in the bottom wall 13 at a constant pitch along the
- the tab contacts 18 are secured in the holes 19 not to move vertically. Tapered surfaces 19a are formed at the bottom ends of retaining holes 19 for convenience of insertion of the tab contacts 18 in the retaining holes 19.
- the tab contacts 18 are made of electrically-conductive metal and
- contact sections 18a and tine or post sections 18b comprise contact sections 18a and tine or post sections 18b.
- the contact sections 18a extend between both sidewalls 15, 15' and the post sections 18b extend outwardly from the bottom wall 13.
- the inner housing 12 comprises, as best shown in FIGS. 2 and 3, end walls 21 and sidewalls 22, 23 extending vertically from a bottom wall 20.
- the sidewall 23 is constructed to adapt to the shape of the sidewall inner surface 15a of the outer housing 11.
- An outer bottom surface 20a is formed as an arcuate surface to enable pivotable movement along the inner bottom surface 13a of the outer housing 11.
- holes 24 for the tab contact sections 18a are formed in the bottom wall 20 at the constant pitch corresponding to the pitch of the tab contacts 18.
- the left side surface of the through holes 24 is sloped by a certain angle with respect to the right side surface as shown in FIG. 2.
- Circular shaft members 25 are formed adjacent the lower ends of 5 the end walls 21 to be pivotally mounted on the bearing sections 16c of slots 16.
- the inner housing 12 is capable of moving clockwise and counterclockwise about the shaft members 25.
- the inner housing 12 has a plurality of vertical cavities 26 disposed Q at a constant pitch along the length of the inner housing 12.
- Receptacle contacts 27 are loaded in the cavities 26 in such a manner to prevent their vertical movement.
- the receptacle contacts 27 are made of electrically-conductive metal and comprise a pair of resilient contact sections 27a extending 5 downwardly, a U-shaped section 27b and a tine or post section 27c.
- the receptacle contacts 27 further comprise a shoulder section 27d at the lower end of the section 27b, and a lance section 27e curved outwardly.
- the shoulder sections 27d engage step portions 28 in an inner surface of the sidewall 22 while the 0 lance sections 27e engage the upper end of openings 29 formed in the sidewall 22, thereby retaining the receptacle contacts 27 in position in the cavities 26.
- the contact sections 18a of the contacts 18 are electrically connected between the resilient pairs of contact sections 27a
- Projections 30 are located at the upper ends of the sidewall 22 and they act as an operator's finger-engaging sections to remove the inner housing 12 from the outer housing 11 and also help to prevent incorrect mating of the two housings 11, 12.
- the post sections 18b, 27c are electrically connected to the circuit boards 1, 2 discussed above by reference to FIG. 6.
- the inner housing 12 is rotated counterclockwise by a given angle in response to the sloped position from the horizontal position of the printed circuit board 1.
- center lines of the contacts 18, 27 coincide with each other; however, in the sloped or slanted position from the vertical position, the inner housing 12 moves via the shaft members 25 while always maintaining desired electrical connection between 5 the contact sections 18a, 27a of the contacts 18, 27.
- the present invention is not limited to an electrical connector for telephones comprising matable base and cover housings, but it is suitable as an electrical connector for applications whereby circuit boards are angularly positioned
- the electrical connector of the present invention is applicable to electrical connections between printed circuit boards mounted on matable base and cover housings of, for example, a telephone.
- a first housing retaining first contacts of a first connector is disposed on the printed circuit board of the base housing and electrically connected thereto while a second housing retaining second contacts of a second connector is disposed on the printed circuit board of the cover housing and electrically connected thereto.
- the first and second connectors 0 are electrically interconnected to provide the following advantages.
- the second connector is pivotally movable with respect to the first connector, thereby enabling the 5 cover housing to be mated with the base housing while the second connector is positioned at a desired angle and the first connector is oriented vertically. Simultaneously, the first and second connectors can be electrically connected.
- the adjustable design of the second 0 connector with respect to the first connector in accordance with the sloped orientation of the printed circuit board of the cover housing makes it applicable to various telephone sets.
