Abstract

An electrical terminal (1) comprises a pair of contacts (2) of metal or metal alloy each having bifurcated arms (3, 4), and a housing (8 or 9) adapted to make a sliding fit axially over the arms of said contact and having an aperture (10 or 11) through which an electric conductor can pass, the aperture being so positioned in the housing that when the housing is slid axially on to the arms of the contact the conductor will be forced between the arms to make an electrical connection with the contact. The terminal may include a base plate (15) and a pressure plate (14) between which a wire may be clamped (Fig. 4, not shown). <IMAGE>

Description

SPECIFICATION Electrical terminals This invention relates to electrical terminals which are especially, but not exclusively, suitable for attaching electric conductors to printed circuit boards.
According to the present invention, an electrical terminal comprises a contact of metal or metal alloy having bifurcated arms, and a housing adapted to make a sliding fit axially over the arms of said contact and having an aperture through which an electric conductor can pass, the aperture being so positioned in the housing that when the housing is slid axially on to the arms of the contact the conductor will be forced between the arms to make an electrical connection with the contact.
The terminal has especial application where the conductor has a covering of insulating material because when the housing, with an insulated conductor positioned in the aperture, is slid axially on to the bifurcated arms of the contact, the edges of the arms bounding the slot between the arms may be so shaped as to form a cutting edge so that they pierce the conductor insulation and make an electrical connection with the conductor.
The housing is preferably made of insulating material, for example polyester, and the contact is preferably made from phosphor bronze which is plated with a tin alloy.
Preferably, the terminal comprises two or more contacts as hereinbefore described which are integral with one another, the bifurcated arms of the contacts preferably extending substantially parallel to one another. Each contact may have its own housing which is a sliding fit on its bifurcated arms or two or more contacts may have a single housing which is a sliding fit axially over the arms of those contacts and which has the same number of apertures as there are contacts, each aperture being aligned with the slot between the bifurcated arms of a contact.
The terminal preferably includes a pressure plate and a base plate between which a drop wire may be clamped to connect the drop wire to the contact.
The invention also includes-a method of making an electrical connection using the terminal hereinbefore described.
The invention is further illustrated by a description, by way of example, of two forms of electrical terminal with reference to the accompanying informal drawings, in which: Figure 1 is a side view of one form of electrical terminal; Figure 2 is a side view of the contact of the electrical terminal shown in Figure 1; Figure 3 is an end view of the housing of the electrical terminal shown in Figure 1; Figure 4 is a side view of an alternative electrical terminal, and Figure 5 is an end view of the terminal shown in Figure 4.
The terminal 1 shown in Figure 1 is attached to a printed circuit board 12 and comprises two contacts 2, each having bifurcated arms 3, 4 (see Figure 2), the edges 5, 6 of the arms bounding the slot 7 between the arms being shaped to form cutting edges, and two insulating housings 8, 9.
Each of the housings 8, 9 is a sliding fit over one of the contacts 2 and has an aperture 10, 11 (see Figure 3) through which an insulated conductor (not shown) can pass. An electrical connection can be made between a contact 2 and an insulated conductor by inserting the insulated conductor through the aperture 10, 11 in one of the housings 9 and then sliding the housing 9 down onto the contact so that the edges 5, 6 of the bifurcated arms 3, 4 of the contact pierce the conductor insulation and make an electrical connection with the conductor.
The terminal 13 shown in Figures 4 and 5 is similar to the terminal 1 shown in Figure 1 except that the terminal also includes a pressure plate 14 and a base plate 1 5 between which a drop wire (not shown) may be clamped to connect the drop wire to the contacts 1 6. In this case, the terminal 1 3 is attached to a printed circuit board 1 7 by a screw fitting 1 8 which also clamps the drop wire between the pressure plate 14 and the base plate 15.
Terminals in accordance with the invention can be reused several times and have the important advantage-that a conductor can be removed from a contact simply by sliding the housing off the bifurcated arms. Another advantage is that special tooling is not required to connect conductors to the contacts.

An electrical terminal comprising a contact of metal or metal alloy having bifurcated arms, and a housing adapted to make a sliding fit axially over the arms of said contact and having an aperture through which an electric conductor can pass, the aperture being so positioned in the housing that when the housing is slid axially on to the arms of the contact the conductor will be forced between the arms to make an electrical connection with the contact.
2. An electrical terminal as claimed in Claim 1, wherein the edges of the arms of the contact bounding the slot between the arms are so shaped as to form cutting edges.
