Definitions
- This invention relates to electrical connectors and particularly to multilead connectors of the jack and plug type.
- Jack and plug type connectors are commonly used to interconnect various types of apparatus and circuits employed in electrical systems and are characterized by a sliding engagement of the corresponding spring elements thereof. Such connectors are quickly separable and facilitate the making and breaking of circuits interconnected thereby.
- the trend in the design of electric systems in general and of automatic telephone switching systems particularly is in the direction of unit design. That is, asystem is divided into a plurality of independent, but mutually cooperable units each of which may be enclosed in a container and, in some cases, hermetically sealed. With such type of construction each outgoing lead from a unit would be terminated on a contact of a connector, the primary role of which would be to disconnect and break circuits fairly rapidly and to permit removal and replacement of the unit in case this becomes necessary for maintenance reasons.
- the connector simplifies such a procedure for wiring and servicing operations compared to the conventional type terminal strip. It has the advantage of eliminating the danger of rewiring leads incorrectly and also avoids the possibility of damage to the connecting wires should it become necessary to change a unit more frequently than might otherwise be expected under ordinary conditions.
- the life objective for sealed electrical equipment units, particularly for telephone central oflice equipment, is forty years and it has been found that considerable trouble could be expected to develop in the nature of open, or high resistance contacts if the conventional sliding type terminal connections were depended upon.
- the connector of this invention is made up of two parts which, for convenience, may be designated a jack and a plug, each of which is provided with a plurality of cooperable contact springs having terminal ends to which individual conductors may be secured and mutually engageable ends normally tinned.
- the contact springs of each'element of the connector of this invention are so disposed that when the plug element is inserted in the jack element no physical contact is made between the respective springs.
- the arrangment is such that the plug springs must be manually flexed in the direction of the jack springs in order to effect contact therebetween.
- this contact is eiiected the tinned ends of the springs are soldered together so that a permanent engagement between the springs is obtained with the plug springs under tension.
- This type of terminal connection imparts to the connection the contact reliability and permanence of soldered connections and at the same time serves to permit quick and convenient separation of the two elements of the connector.
- Fig. 1 is a front view of the connector of this invention
- Fig. 2 is a side view of the connector shown in Fig. 1;
- Fig. 3 is a rear viewof the connector shown in Fig; l'and illustrates certain of the plug and jack springs in electrical contact and certain others 'intheir normal disengaged relationship;
- Fig. 4 is a side view of the connector showing the normal clearance between the jack and plug springs prior to the soldering operation;
- Fig. 5 is an exploded view of the connector showing the jack and plug elements of the connector separated.
- the plug element of the connector as shown at A in Fig. 5 comprises an insulating block Ill the upper edge of the block. As will appear here:
- the extent to which the plate l3 extends. above the block 10 corresponds to the height of the jack insulating block.
- Substantially mid-way of the vertically extending portion of plate t3 and located near each end thereof is a hole which accommodates a guide pin [4.
- the plug springs 52 project forwardly and rearwardly from the block I G and the springs of the upper row extend rearwardly further than, the springs of the lower row.
- the ends of the rearwardly projecting portions of springs I-2 are tinned. The forward ends of the springs provide terminals to which individual wires may be connected.
- the jack element of the connector shown at B in Fig. 5 comprises an insulating biock l5 which supports two rows of equi-spaced flat contact springs l6 which are held in position in any suitable manner. If desirable the jack element may be made up of alternate springs and insulating spacers held together as a unitary structure by screws IT.
- the insulator I5 is provided with two centrally located cylindrical bores or holes M which snugly accommodate the guide pins l of the plug.
- each jack spring is provided with terminals to which external wiring maybe connected and their lower ends are twisted at right angles to the normal plane of the springs and are tinned.
- the lower edge of each jack spring is provided with a concave or semicircular slot. IS, the inner peripheral contour of which is such as to conveniently accommodate the circularly sectioned plug springs l2.
- the arrangement of the jack springs corresponds to that of the plug springs, that is, the springs of the two rows are arranged in staggered relation.
- the connector of this invention combines reliability of contact with facility of separation of the two elements thereof and thereby satisfies essential requirements for such a device when employed with unitary circuit and apparatus.
- assembly units whose anticipated servicev life is such as to preclude the use of sliding terminal connections which are subject to opens and faults caused by dirt, dust, etc.
- a plug having a plurality of equi-spaced contact springs
- a jack having a plurality of equi-spaced contact springs
- cooperable means on said plug and jack units for supporting one unit on the other unit. so that the contact springs of one of said units are normally in disengaged relation to the contact springs of the other unit and require flexing in the direction thereof to effect engagement therebetween, and fusible solder connecting the flexed springs of the said one of said units with the springs of the other of said units.
- a plug unit comprising an insulator, a plurality of plug springs horizontally disposed and mounted in said insulator
- a jack unit comprising an insulator, a plurality of jack springs vertically disposed and mounted in said jack insulator, a guide pin associated with said plug unit, the insulator of said jack unit having a hole therein for the reception of said guide pin when said plug and jack units are. assembled, and the relative disposition of thejsprings on their respective blocks being such that upon assembly of said plug and jack units the said vertically disposed jack springs have their end edges in spaced alignment with the horizontally disposed plug springs so that said plug springs require manual tensioning in. the direction of, said jack springs to effect engagement. therebetween, and a fusible material joining the tensioned plug springs with the inner edges. of corresponding jack springs.
- a pair of mutuallycooperable electric circuit connector units each comprising a plurality of spaced contact springs, means mounting said units relative to one another so that the engageable ends of the springs thereof are mutually disposed at right angles when said units are in assembled relation, and means comprising fusible solder electrically joining individual cooperating spring ends of said units, the springs of said units being mutually flexible relative to one another whereby, when so flexed, corresponding spring ends of said units are held in engagement under tension by said solder means and are automatically spatially separated upon fusing of said solder means.
