5 Claims. (Cl. 339-176) pins have been forced by a press into holes in the terminal block and fixed therein by forced fit. The terminal blocks have then beensecured together and the contact portions of the terminals forced into engagement with .one another.
When it was proposed to separate the terminals it was necessary to pry the blocks apart which, in many cases, resulted in damaging the terminal pins. In some instances the terminal pins comprise spring pressed contact portions carried within sleeves which were forced into holes in theblocks and while this made separation of the blocks easier, the terminals were more costly and required a press to install them. Furthermore, it was particularly difiicult without special tools to removethe terminal pins from the terminal block without permanently damaging the terminal.
The present invention overcomes these difficulties by providing a connector construction which is easy to manufacture and assemble and in which the contacts on the opposed terminal blocks can be readily separated, removed and replaced if necessary all without the need of special tools.
In carrying out the present invention, the terminal blocks of insulated material are provided with aligned bores in which terminal pins are slidably mounted. They are readily insertable into the bores and are yieldably urged into an engaging position by means located in the bores. The terminal pins are maintained in the terminal blocks by means of a removable closure.
A feature of the invention resides in the simplicity of the construction and assembly of the device wherein the terminals which may be simple screw machine parts may When the terminal blocks are clamped together to f rm a detachable connector, the. cooperating terminal pins engage one another and the yielding means permits proper contactbe'tween the terminal pins without undue force being applied thereto as might damage the terminal At the same time the yielding means will be compressed and, apply a determined pressure to maintain the contacts in good electrical engagement.
When it is desired to separate the terminal blocks the clamping means is released and the pins are readily sepa-rated without damage to the contacting surfaces.
If it is desired to make a different contact arrangenerin, thebores in the terminalbloclts. H
In the'preferred form of the invention, the contacting 2 portions of the terminal pins are formed as male and female contacts embodying a tapered socket and a tapered point which, when the blocks are brought together, insure proper contact engagement in the terminals.
Other features and advantages will be apparent from the specification and claims when considered in connection with the drawings in which:
Figure 1 shows an assembled view partially in section, of the connector.
Fig. 2 shows a view of the connector, partially in section, with the terminal blocks separated.
Fig. 3 shows an end view of the connector.
As shown in the drawing the electrical connector of the ice present invention comprises opposed similar blocks 10 of invention they are shown as being disposed in two parallel rows as is clear from Fig. 3. In each of the bores there is slidably mounted an elongate terminal pin 13.
In the preferred form of the invention, the terminal pins are formed as a unitary structure of a diameter to slide in the restricted bore 11a and having a contacting portion 13a at their inner ends, a conductor connecting nl'eans 13b at the outer end and a'projection 13c inter- .mediate the ends of the pin adapted to engage the stop shoulder 12 and limit the inward movement of the terminal pins in an engaging position as shown in Pig. 2 wherein the contacting portion of at least one of the pins projects beyond the inner face of the block.
While the projection 13c may be a pin'or the like extension, in the illustrated form of the invention, it is formed by a collar whose outer surface 14 engages the Wall of the enlarged portion of the bore to provide a radially outwardly disposed bearing for the terminal pin.
Each terminal pin is normally urged to the engaging position as shown in Fig. 2 by a yielding means. In the illustrated form of the invention, this comprises a spring 15 insertable in the enlarged bores from outer end of the bore and surrounding the terminal pin with the inner end of the spring engaging the collar. The bores are then provided with a closure member which engages the outer end of the spring and retains the terminal pin in the bore. While the closure member may be formed as individual closures for each bore, in the present illustrated form of the invention it comprises a closure plate 16 having apertures therein in alignment with the bores for'slidably receiving the projecting end of the terminal pin. The closure plate is releasably secured to the block by screws 17.
The cooperating contact portions 13a at the inner ends of the terminal pins may be made in anydesired form. In the present preferred form of the invention, these contact portions are shown to be male and female members, the female member being comprised in a conical socket 18 and the male member'comprising a tapered point 19 which when brought together insures accurate alignment of the terminal pins and good contact between the engaging surfaces.
After the required conductors 20 have'been secured'to the terminal pins the two contact blocks are brought together in opposed face to face relation to bring the contacting portions into engagement to connect a plurality of circuits as shown inFig. 1. While the blocks may be brought together and secured or clamped by any suitable means, in the illustrated form of the invention the clamping means comprises bolts 21 passing through apertures 22, 23 in the'two terminal blocks and closure plates. As
the bolts are drawn up the springs will yield and prevent jamming of the contacts while still maintaining them pressed together with sufficient pressure to provide good electrical contact between them.
When it is desired to break the circuit connection it is merely necessary to release the bolts and separate the blocks. Since a forced fit of the contact engaging surfaces the contacts has not occurred, they are readily separated without any damage to the contacting surfaces.
From the foregoing it will be apparent that connector of the present invention can be easily and cheaply manufactured since the terminal blocks and closure members are identical and can be formed by the same molds or fixtures and the terminal pins are a unitary structure which can be readily produced in quantity on a screw machine and require no subsequent assembly operations.
Further the present invention produces a connector in which the elements thereof can be readily and easily assembled without the use of any presses or special tools by merely inserting the terminal pins into the bores through the outer ends thereof, placing the spring in position and securing the closure member in place by means of the locking screws. Should it be desired to replace a terminal pin or to rearrange the pins to produce a predetermined pattern, this can be accomplished by removing the closure member and withdrawing and replacing the terminal pins as desired, all without any damage to the terminal pins.
The connection or disconnection of a plurality of circuits by the present invention is easily and quickly accomplished since the terminal blocks, after the terminal pins have been assembled therein and connected to the conductors of said circuits, are placed in face to face relation with the contacting portions of the terminals in engagement. The bolts are then tightened clamping the blocks together. The springs will yield during the clamping operation to prevent forcing together of the terminal pins which might result in damage to the terminal pins while at the same time urging them together to provide good electrical engagement. Should it be desired to break the connection it is merely necessary to release the bolts and separate the blocks since the terminal pins will freely separate because of any lock force fit between them thus eliminating any danger of damage to the terminal pins incident to prying the blocks apart as was heretofore required.
Since the blocks can be readily assembled and released without substantial force being employed, the terminal blocks can be made of any desired shape and size as may be required.
The above advantages of the present invention are particularly important in aircraft and the like installations because of the versitility, simplicity and reliability of operation of the connector, all without necessity of special tools.
