Description

Jan. 21, 1969 s. r. DEAKIN SELECTOR BOARD Filed July 5, 1966 United States Patent 28,528/ 65 US. Cl. 339-48 Claims Int. Cl. H01r 29/00 ABSTRACT OF THE DISCLOSURE An electrical selector board comprising at least two superposed crossing sets of rows of socket contacts supported on insulating material. At each crossing point one socket contact of each set is aligned with a socket of the other set, with the sockets of each row being spaced apart along a length of strip material. The strips are transversely bent to form humps between adjacent sockets and to provide the strips with lengthwise resilience. The supporting insulating material has holes therein associated with the sockets, and slots may be provided in the insulating material between the holes for receiving the humps.
The invention relates to electrical selector boards (sometimes known as patch boards) of the kind comprising at least two superposed crossing sets of rows of socket contacts, there being at each crossing point one socket of each set aligned with a socket of the other set, or each other set. The contacts of each row are usually, but not necessarily, electrically interconnected and they may be integral with one another. At least one, and it may be all, of the contacts at each crossing point is open at each end to provide a thronghway for a plug which can be inserted into a throughway and extend into electrical connection with a socket aligned therewith. The sockets may be supported on one or more sheets of insulating material. One example of a board of this kind is disclosed in British Patent Specification No. 934,627, the socket contacts in this board being resilient.
The present invention provides a selector board of the above kind in which the sockets are formed by drawing or pressing up edge portions around holes in sheet or strip material.
The sockets may be of rigid construction and be intended for reception of resilient plug pins, for example pins as disclosed in our copending application (British No. 28,528/65).
In one form of the invention the sockets have the form of tubular eyelets pressed up or down from strip material.
The sockets may be formed in rows along strips of material and the strips may be transversely bent to form humps between adjacent sockets and to provide the strip with lengthwise resilience.
The contacts may be secured to sheet insulating material by the sockets which are received, and held, in holes in the insulating material. The sockets may be held by expanding them into the holes or by turning over or rivetting the rim of the pressed up socket or eyelet.
Some specific embodiments of selector boards according to the invention will now be described, by way of example, with reference to the accompanying drawings in which:
FIGURE 1 shows a cross-section through a representative portion of a board,
FIGURE 2 shows a portion of one of the contact strips used in the board of FIGURE 1,
FIGURE 3 shows an alternative form of contact strip,
3,423,716 Patented Jan. 21, 1969 "ice FIGURE 4 shows a portion of an insulating sheet for use with the strip of FIGURE 3,
FIGURE 5 is a view, similar to FIGURE 1, form of board,
FIGURE 6 shows an alternative form of contact strip,
FIGURES 7 and 8 show alternative forms of individual socket contacts, and
FIGURE 9 shows a portion of an insulating sheet.
Referring first to FIGURES 1 and 2, the selector board comprises four sheets 10 to 13 of insulating material secured in spaced relation. Secured to the sheet 13 there are parallel strips 15 of contacts, each as shown in FIGURE 1, the strips being seen in end view in FIGURE 1. The strips are formed with socket eyelets 16 which pass through holes in the sheet 13 and are turned over at the rims 17 to secure the strips in place. Between each pair of adjacent sockets, the strips are bent to provide transverse humps 19 thereby giving to the strips a limited degree of longitudinal resilience to facilitate registration of the sockets and holes.
The sheet 11 has similar rows of contacts, the strips being at right angles to the strips in sheet 13.
Sheets 10 and 12 have holes 20 aligned with the sockets at each crossing point of the strips. Connection tags 21 are soldered to the ends of the strips on sheet 11.
In use, a resilient contact pin, e.g., as disclosed in our copending application aforesaid, is inserted into a pair of the aligned sockets at a crossing point of two strips to make an electrical circuit or connection between the strips.
FIGURE 3 shows a contact strip which differs from the strip of FIGURE 2 in that the humps 29 are on the same face of the strip as the sockets 16. This strip may be used with a sheet 30 as seen in FIGURE 4, the sockets 16 engaging in the holes 31 and the humps in slots 32 or 33 according to which way the strip runs. The sheet is equivalent to 11 or 13 in FIGURE 1.
FIGURE 5 shows a modification in which only three insulating sheets are required. The height of the sockets 36 in the sheet 37 is less than the thickness of the sheet so that the sockets are held out of contact with the sockets 38 in the sheet 39. The sockets are expanded into gripping relation on the holes. Integral connection tags 40 are provided in the strips 41.
FIGURE 6 shows an alternative form of contact strip having sockets provided by bent-up tongues 46. These tongues pass through rectangular holes in the insulating sheets and are bent over at their free ends to grip the sheet.
FIGURE 7 shows an individual socket contact equivalent to one of the sockets in FIGURE 3. The socket 16 will be held in a hole as in FIGURE 1 and the hump 50 will engage in a slot or recess in the sheet to locate the contact. The contacts will be assembled in rows. A connection tag 51 is provided on each socket.
FIGURE 8 shows a contact similar to that of FIGURE 7 except that the hump is omitted and the connection tag passes through a hole in the supporting sheet.
FIGURE 9 shows an insulating sheet 55 which may be used, for example, as the sheet 37 or 39 in FIGURE 5. The sheet is of thinner material than sheet 37 or 39 and the effective thickness is increased, to receive the socket eyelets, by partial shearing of slugs 56, the slugs having holes to receive the sockets.
I claim:
1. An electrical selector board comprising at least two superposed crossing sets of rows of socket contacts supported on insulating material, one socket contact of each set being aligned with a socket contact of the other set at each point where the rows of the respective sets cross, the socket contacts of each row being spaced apart along a length of strip material, the strips being transversely of another bent to form humps between adjacent socket contacts and to provide the strips with lengthwise resilience.
2. A selector board as claimed in claim 1 in which the socket contacts are of rigid construction, and said lengthwise resilience provided by said humps facilitating registration of the socket contacts of one set with those of the other set.
3. A selector board as claimed in claim 1 in which the socket contacts are in the form of tubular eyelets drawn up from one face of the length of strip material and said humps project down from the opposite face of the length of strip material.
4. A selector board as claimed in claim 1 in which the socket contacts of each row are formed by holes in said strip material with the edge positions of the strip material surrounding said holes being drawn up around the holes.
5. A selector board as claimed in claim 1 in which the socket contacts are drawn up from one face of the length of strip material, said humps projecting up from the same face of said length of strip material.
6. A selector board as claimed in claim 5 in which the insulating material on which the rows of socket contacts are supported has holes therein for receiving the drawn up socket contacts therein, and said insulating material having slots therein between said holes for receiving said humps in said slots.
