Description

ELECTRICAL CONNECTOR AND AN ELECTRICAL CONTACT ELEMENT This invention relates to an electrical connector for connecting end portions of the metal cores of electrical leads to electrical conductors on a printed circuit board and the invention also relates to a stamped and formed electrical contact element which is suitable for use with the connector.
The invention is intended to provide an electrical connector of optimum contact density, especially for industrial or domestic use, which enables the stripped end portions of insulated electrical leads to be connected to circuit board conductors without the need for tooling and which comprises only a moulded insulating housing and a set of identical stamped and formed electrical contact elements. Particular use for the connector, is for the connection of supply leads to a fluorescent tube assembly, for example in a home or an office, rapidly, and without the exercise of skill.
According to one aspect of the invention, an electrical connector for connecting end portions of the metal cores of electrical leads to electrical conductors on a printed circuit board, comprises a one piece moulded insulating housing having a body and a cover, and a series of identical one piece, stamped and formed electrical contact elements, the body having a top face, a bottom face, opposite front and rear walls and defining a series of parallel, juxtaposed, elongate, contact element receiving cavities each opening into said top face, the cover being hinged to the body and being latchable thereto in a closed position covering said top face, each contact element being disposed in a respective one of said cavities and comprising an elongate, cantilever contact spring extending between said opposite walls of the body, a flange proximate to the free end of the contact spring, and a contact tail depending from the bottom face of the body for insertion through a hole in the printed circuit board, the free ends of the contact springs of alternate ones of the contact elements being oppositely directed and each being positioned proximate to a respective one of said opposite walls, the cover having a series of through, lead core receiving openings therein each of which is aligned with the free end portion of a respective one of said contact springs when the cover is in its closed position, to allow the end portion of the core of an electrical lead to be inserted through the opening to depress the contact spring and to cause the free end portion of said core to be trapped between the free end of the contact spring and the flange proximate thereto.
Conveniently, the cover may be arranged to hold down the contact elements in their cavities, when the cover is latched in its closed position, whereby no latching means for example latching tongues need be provided on the contact elements in order to retain them correctly positioned in their cavities.
In order to enable the leads to be readily disconnected from the circuit board conductors, access openings may be provided in the cover for the insertion of a probe to displace the free ends of the contact springs from the end portions of the lead cores in order to enable the leads to be withdrawn from the connector.
According to another aspect of the invention, an electrical contact element which has been stamped and formed from a single piece of sheet metal stock, comprises an elongate, substantially rectangular plate having a top edge, a bottom edge, and first and second ends, a first flange projecting from the first end of said plate normally thereof, a second flange projecting from the second end of said plate normally thereof, a contact spring having a root portion projecting normally from said plate from the top edge thereof proximate to the first end of the plate, and a cantilever spring portion extending from the root portion obliquely across said plate and towards the second end of the plate and having a free end proximate to, but spaced from, the second flange, and a contact tail depending from the bottom edge of the plate between said flanges.
An embodiment of the invention will now be described by way of example with reference to the accompanying drawings in which: Figure 1 is an enlarged isometric view of a contact element of an electrical connector for connecting electrical leads to electrical conductors on a printed circuit board: Figure 2 is an isometric view taken from above, of an insulating housing of the connector with a cover of the housing in an open position: Figure 3 is a similar view to that of Figure 2 but being taken from below: Figure 4 is a top plan view of the housing with the cover in a closed position:: Figure 5 is an exploded isometric view of the connector with the cover in its open position and illustrating the arrangement of contact elements in the housing; Figure 6 is an isometric view of the connector with the cover in a closed position; Figures 7 and 8 are cross-sectional views of the connector with the cover in its closed position and illustrating respective stages in the insertion of a stripped end portion of an electrical lead into the connector; and Figure 9 is a similar view to that of Figure 8 but showing the use of a probe to release said end portion from the connector.
An electrical connector 2 for connecting electrical leads to electrical conductors on a printed circuit board comprises an insulating housing 4 containing four electrical contact elements 6.
The housing 4 which was moulded in one piece from a suitable insulating material, comprises a substantially rectangular body 8 and a cover 10 connected to the body 8 by means of a hinge 12. The body 8 defines four elongate, parallel, juxtaposed, contact element receiving cavities 14a, 14b, 14c, and 14d, respectively, each cavity opening into a top face 16 of the body 8. The body 8 has a front wall 18, an opposite rear wall 20, opposite side walls 22 and 24, respectively, and a base wall 26 connecting the walls 18, 20, 22 and 24. There upstands from the base wall 26, in each cavity 14, a contact element locating projection 28 which is rectangular and is upwardly elongate, and a contact spring stop 30 spaced from the projection 28 and presenting an inclined, contact spring stop surface 32.The base wall 26 defines a lead core receiving, circular crosssection well 34 on the side of the stop 30 remote from the projection 28, in each cavity 14. A contact element tail receiving hole 36 extends through the base wall 26 on one side of each stop 30. On the side of each projection 28, remote from the stop 30, the projection 28 co-operates with the respective front wall or rear wall, of the body 8, as the case may be, to define a contact element flange receiving slot 38 having an upwardly flared mouth 40.
Be it noted that the cavities 14 are alternately oppositely oriented.
In each of the cavities 14a and 14c the projection 28 is proximate to the rear wall 20, as best seen in Figure 2, the projection 28 in each cavity 14b and 14d being proximate to the front wall 18. Thus the well 34 communicating with each cavity 14a and 14e is proximate to the front wall 18, the well 34 communicating with each cavity 14b and 14d being proximate to the rear wall 20.
The front wall 18 is divided to provide resilient latch arms 42 formed with latching heads 44 standing above the top wall 16. The underside of the base wall 26 is formed with stand-off lugs 46, one at each corner of the body 8.
The upper face of the cover 10 is formed with four upstanding, lead receiving collars 48a, 48b, 48c, and 48d, each defining a part circular lead receiving socket 50 communicating with a probe receiving channel 52 extending along the socket 50, and with a lead core receiving opening 54 extending through the cover 10 beside the channel 52 and opening into the underside of a rib 56a, 56b, 56c or 56d, as the case may be, on the bottom face of the cover 10. Each rib 56 has a central slot 58 bounded by a contact element hold down surface 60. Each collar 48b and 48d has a latch head receiving notch 62 aligned with a latch head receiving slot 64 proximate to the forward edge of the cover 10.
Be it noted that the collars 46a and 46c are offset forwardly of the cover 10 with respect to the collars 48b and 48d, the collar 48a being offset from the collar 48b towards the side wall 22, the collar 48c being offset from the collar 48b towards the side wall 24 and the collar 48d being offset from the collar 48c towards the side wall 24, all as best seen in Figure 6. Thus the ribs 56a and 56c are oriented with their openings 54 proximate to the forward edge of the cover 10, the ribs 56b and 56d being oriented with their openings 54 proximate to the hinge 12.
As best seen in Figure 1, each contact element 6, which has been stamped and formed from a single piece of sheet metal stock, comprises a contact spring support 66 having an elongate, main plate 68, from one end of which extends a first flange 70 and from the other end of which extends a second flange 72, the flanges 70 and 72 extending normally of the plate 68 and in the same direction. A cantilever contact spring 74 has a planar root portion 76 joined to the upper edge 78 of the plate 68 and extending longitudinally thereof and at right angles to the plate 68 in the same direction as the flanges 70 and 72, and a cantilever contact spring portion 80 projecting obliquely, downwardly, across the plate 68, from the root portion 76, towards the flange 70. The contact spring portion 80, has a free end 81 proximate to, but spaced from, the flange 70.The edge 78 is notched at 82 and 84 during the stamping operation, to facilitate the bending out of the flanges 70 and 72, respectively.
There depends from the lower edge 86 of the plate 68, a contact tail 88 formed with a longitudinal reinforcing rib 90, which extends into the plate 68.
When assembling the connector 2, as will be apparent from Figure 5, the first contact element 6 is loaded into the cavity 14d with its flange 70 directed rearwardly of the body 8, the second contact element 6 is loaded into the cavity 14c with its flange 70 directed forwardly of the body 8, the third contact element 6 is loaded into the cavity 14b, with its flange 70 directed rearwardly of the body 8, and a fourth contact element 6 is loaded into the cavity 14a, with its flange 70 directed forwardly of the body 8. Thus the contact spring portions 80 of each adjacent pair of contact elements 6 are oppositely directed.In each case, the contact tail 88 of each contact element 6 stems through a respective hole 36 in the base wall 26, the root portion 76 of the contact spring 74 resting on the top of a respective projection 28 with the flange 72 received in the respective slot 38 guided by its mouth 40 and the flange 70 extending into the respective well 34, as best seen in Figures 7 to 9.
The connector 2 is supplied to a customer with the cover 10 in its closed position on the body 8, so that the head 44 of each latch arm 42 is passed through the respective slot 64 in the cover 10 to lie in the notch 62 thereabove.
Thereby the cover 10 is firmly latched in its closed position as best seen in Figure 6. In the closed position of the cover -10 each hold down surface 60 engages the root portion 76 of the respective contact spring 74 to hold the portion 76 down on the projection 28, each collar 48 being aligned with the end part of a respective contact spring portion 80.
For use, the connector 2 is mounted on a circuit board CB, shown in broken lines in Figure 7, with the contact tails 88 projecting through holes in the board CB. The tails 88 are then soldered to respective conductors on the board CB. The conductors may, for example, be connected to inlets of a fluorescent tube assembly. In order to connect supply leads L to the fluorescent tube assembly, or other electrical apparatus, the end portions of the leads are stripped of insulation to expose end portions of their metal cores C.The user inserts each core C of each lead L through a respective socket 50 as shown in Figure 7, so that the free end of the core C passes through the opening 4 therebeneath to impinge against the free end part of the contact spring portion 80 aligned with that opening 54, and advances the lead L as shown in Figure 8, until the free end of the core C bottoms in the well 34 after having resiliently depressed the contact spring portion 80 from its full line, to its broken line position, whereby the free end 81 of the contact spring portion 80 engages the core C and is held there against by the return force of the portion 80, acting in the direction of the arrow B in Figure 8.
In this position of the lead L the end portion of the insulation thereof is received in the socket 50 and the lead L is firmly locked in the connector 2.
If a lead L is to be disconnected from a connector 2, a probe P is inserted through the respective channel 52 in the direction of the arrow D in Figure 9, to engage the free end part of the contact spring portion 80 therebeneath, so as to depress it against the stop surface 32 of the stop 30, whereby the free end 81 of the contact spring portion 80 is disengaged from the core C so that the lead L can be withdrawn from the connector 2.
The insertion and the removal of the leads L can be quickly and easily carried out by an unskilled person at an industrial or at a domestic site, for example.
The connector 2 is of optimum contact density and compactness, by virtue of the alternate arrangement of the contact elements 6 and their cavities 14, and the consequent staggering of the collars 48.
The contact elements 6 are identical and can conveniently be produced in strip form and the housing 4 is a one piece moulding. No screws or other fasteners are needed in the construction of the connector 2 and the contact elements do not need latching tongues or like retention means which could easily be damaged when the contact elements are handled.
