Description

ELECTRICAL CONNECTOR
FIELD OF THE INVENTION
The present invention relates broadly to the field of connectors, such as connectors used in printed circuit boards (PCB) and to a method of controlling electrical characteristics of an electrical connector.
BACKGROUND

DETAILED DESCRIPTION
Figure 2 illustrates a perspective view of a SAS (serially attached SCSI) receptacle 20 according to an example embodiment. The elongate receptacle 20 comprises a dielectric housing which is moulded to accommodate electrical terminals 28, 30. The receptacle 20 has three sets of arrays, e.g. 33, arranged on different planes of the receptacle 20. A first array 31 consists of twenty-two terminals 28 of 1.27 mm pitch and is located towards one end 22 of the receptacle 20, along one edge thereof, each terminal 28 being positioned in their respective chambers 36. The terminals 28 of the first array 31 usually connect power lines. A second array 33 consists of eight terminals 30 of 0.8 mm pitch. The second array 33 is located towards the center 24of the receptacle 20 and on the edge thereof which is opposite to the edge having the first array 31. Each terminal 30 is positioned in respective slots 19. The terminals 30 of the second array 33 usually connect signal lines. A third array 35 consists of seven terminals 28 of 1.27 mm pitch and is located on the other end 26 of the receptacle 20 and on the same edge thereof as that of the first array 31 , each terminal being positioned in their respective chambers 36. The terminals 28 of the third array 35 usually connect signal lines.
The first 31 and the third 35 arrays are located on the same edge of the receptacle 20 and are flush with the outer surface of the receptacle 20, whilst the centre portion 24, housing the second array 33, protrudes out of the wall 22 of the receptacle 20.
Each of the ends 20, 26 of the receptacle 20 are terminated with a vertically positioned pillar 38 and a horizontally positioned base 40. On one edge of each of the base 40, a metallic terminal 42 is formed in a vertical direction to enable the receptacle to be inserted on to a
PCB thereby providing rigidity to the receptacle 20 . The tail portions of the electrical terminals 28, 30 protrude the receptacle 20 and are of the press-fit type i.e. the tail portions of these terminals are resilient in a lateral direction to provide support to the receptacle connector and the PCB when the receptacle connector is inserted in to a PCB during assembly.
The center portion 24 comprises the array 33 of electrical terminals 30 that are seated in slots 19. Since the center portion 24 is used for electrically connecting signal lines, the pitch of the terminals 30 are usually lower than the pitch of those electrical terminals 28 that carry other lines e.g. power lines. The design of the low pitched electrical terminals 30 should be aimed at improving signal integrity and parameters, such as reduction of cross-talk. One way of achieving such an object is to reduce the dielectric constant of the dielectric material of the housing. Reducing or removing the dielectric material at the center portion 24 reduces the value of dielectric constant between the terminals 30. This results in reduced capacitance, which is very important in high frequency applications.
The reduction in dielectric material is achieved in the example embodiment by partially removing or reducing the dielectric material of the protruded center portion 24. The protruded center portion 24 has upper and lower portions 200, 2020 respectively. The width 29 of the protrusion of the lower portion 202 is greater that of the width 27 of the upper portion 200.
The upper and lower portions 200, 202 are connected by an intersecting portion 21 , which is shown to be inclined in the example embodiment. The intersecting portion 21 may also be perpendicular to the edge of the receptacle 20. The construction of the upper portion is a set of recesses 23. The electrical terminals 30 are seated in the recesses 23.
The body of the electrical terminals 30 is seen partially embedded inside the slots 21 in the lower portion 202 of the centre portion 24 of the receptacle 20. The tail of each of the electrical terminals 30 protrudes the receptacle 20, to enable electrical connection with a PCB. The tail portions of the electrical terminals 30 are of the press-fit type. i.e. these terminals are resilient in a lateral direction to provide support to the receptacle connector and the PCB when the receptacle connector is inserted into a PCB during assembly.
The receptacle 20 is designed to receive a plug 500, as shown in Figures 4a and 4b, of a cable or another PCB, and as the plug co-operably mates with the receptacle 20, electrical connections between the respective terminals 28, 30 of the receptacle 20 and the plug are established.
Figure 3a illustrates a perspective view of a SAS (serially attached SCSI) receptacle 30 according to the second embodiment. When compared to the first embodiment, the construction of the receptacle differs in the construction of the centre portion 24.
As in the second embodiment, the center portion 24 comprises an array 33 of electrical terminals 30 that are received in slots 49. The protruded center portion 24 has upper and lower portions 302, 304 respectively. The width 50 of the lower portion 304 is greater than the width 52 of the upper portion 302. The upper and lower portions 302, 304 are connected by an intersecting portion 48, which is shown to be inclined in the example embodiment. The intersecting portion 48 may also be perpendicular to the edge of the receptacle 300.
Unlike the second embodiment, the part of the upper portion 302 lacks entirely the dielectric material resulting in an opening 46 in wall 22. The slots 47 are present in the bottom portion 304 for receiving the terminals 30, which extend across the opening formed in wall 22. The heads of the electrical terminals 30 are positioned in their respective slots 49. The tails of the electrical terminals 30 protrude the receptacle 300 to enable physical contact with a PCB.
Figure 3b is a view of Figure 3a with electrical terminals of 30 of the array 33 dis-assembled, fully exposing the opening 46 in wall 22. Slots 49 can be seen on the top surface of the upper portion. Further, slots 47 are also present on the bottom surface of the upper portion. Each electrical terminal 30 has a head 54, a body 56 and a tail 58. The head 54 has a compression tip to enable physical connection with electrical terminals of a plug. The body 56 is elongate and is bent at appropriate positions for achieving resiliency. The tail portion 58 is press-fit type having resilience in the lateral direction of the terminal. This is to effectively insert a receptacle onto a PCB during assembly.
The number of arrays and shown above can be less or more than three. The position and designation of the arrays for carrying signal and power lines can be altered. The number and pitch of electrical terminals of the arrays can be varied with a corresponding variation in the length of the receptacle.
The dimensions of the arrays can be varied. The dimension and pattern of the removal of dielectric material may be altered.
The tail portions of the electrical terminals 28, 38 are shown to be press-fit. Other types, such as compression, through hole, surface mount etc. may also be employed
It will be appreciated by a person skilled in the art that numerous variations and/or modifications may be made to the present invention as shown in the specific embodiments without departing from the spirit or scope of the invention as broadly described. The present embodiments are, therefore, to be considered in all respects to be illustrative and not restrictive.
