INTERLQCKING SHIELDED CONNECTOR Filed July 29, 1965 FIG.

INVENTORS CURTIS R. A. JOHNSON JOSEPH C. STEUR AGENT 3,329,925 Patented July 4, 19 67 time 3,329.925 INTERLOCKING SHIELDED CONNECTOR Curtis R. A. Johnson, Flourtown, and' Joseph C. Steur, Ambler, Pa., assignors to Leeds & Northrup Company, a corporation of Pennsylvania Filed July 29, 1965. Ser. No. 475,743 11 Claims. (Cl. 339-91) ABSTRACT OF THE DISCLOSURE An electrical connector mounted on a panel with round head screws is constructed so that the screw heads overhang the connector body. A mating connector is surrounded by a shielding housing and has fiat springs with crimped ends mounted inside the housing. These springs cam over the round heads of the mounting screws to interlock the connectors in their mated position with the housing abutting the panel. The interlocked and shielded connectors can be disengaged by the application of sufilcient force to the housing to disengage the crimped ends of the springs from the heads of the mounting screws.

This invention relates to electrical connectors having a housing for shielding the connections with the housing being designed with an interlock to maintain the connectors coupled in mating position. More particularly this invention is related to the locking means for interlocking such shielded connector housings.

Connectors which are utilized for the connection of elements of electrical circuits frequently require shielding to avoid pickup of unwanted signals or noise in the circuits being connected. In such circuits the wires which are to be connected by the connector are usually shielded, but it is also necessary in order to avoid pickup from external sources that the connectors for providing the connections should also be shielded. Such shielding of the connectors may advantageously be accomplished by the use of an electrically conductive housing for the connectors which encloses them when they are coupled together, that is when the connectors are mated for the completion of electrical circuits.

It is an object of this invention to provide an improved means for locking mating connectors having a shielding housing in avoidance of accidental disconnection of the connector.

Another object of this invention is the provision of an inexpensive means for providing the locking of connectors in their mated positions without the necessity of providing the locking means as a part of the connector.

Another object of this invention is the provision of means for mounting one connector block so as to provide means for interlocking the other connector block when the respective connector elements are mated for completion of their associated electrical circuits.

In carrying out this invention there is provided an interlocking means for a shielded connector which utilizes a spring element mounted to one of an interconnecting pair of electrical connectors. The spring element is constructed to have a crimp at one end. The other of the pair of electrical connectors is mounted by a fastening means which has a head so shaped as to overhang the edge of the connector that is mounted. This overhanging edge forms a camming surface over which the crimped end of the spring element rides and with which the crimped end interlocks when the electrical connectors are mated.

For a more detailed understanding of the invention and for an illustration of a preferred form thereof reference is made to the drawings in which:

FIG. 1 is a front elevation of the connectors with the shielding housing showing the connectors in their mated position with the interlock engaged.

FIG. 2 is a partial front elevation of the connector blocks showing the housing surrounding one of the blocks and showing the connectors disengaged in a noninterlocked position.

In FIG. 1 a first connector includes connector block 10 having a male end portion 11 shown interlocked with a connector block 14 of a second connector, connector block 14 having a female end 15. The connector block 10 and the connector block 14 are shown in their mated positions with the male end 11 of block 10 inserted into the female end 15 of block 14.

The connector block 14 is shown as being mounted to a metal panel 18 such as an amplifier chassis by a plurality of fasteners 20 inserted through holes on the edge of block 14. In FIG. 1 the fasteners 20 are shown as being of the type which has a slotted head for receiving a screw driver. Such fasteners are generally of the type having threads along the shaft portion (not shown) such as machine screws, for example.

As shown in FIG. 1, the heads of the fasteners 20 are of diameter suflicient to overhang the edge 24 of the connector block 14. That portion of the heads of fasteners 20 which overhang the edge 24 may be a small portion. The overhang may advantageously be on the order of three or four thousandths of an inch. In FIG. lthe fasteners 20 are shown as having rounded heads. Other types of fasteners may be used which have heads which are not constructed to have the amount of curvature shown in FIG. 1.

The connector block 10 is shown in FIG. 1 as being mounted internally to an electrically conductive shielding housing 30 by machine screws 32. The machine screws are also shown being utilized as a means for afiixing internally to the housing 30 one end of each of two retainers, such as the flat spring elements 34.

The flat spring elements 34 have horizontally disposed portions 34a which are engaged by the heads of the machine screws 32. Extending from each of the portions 34a is a length which is angled toward the interior of the housing 30. These lengths of the fiat spring elements 34 are identified by the reference character 34b and each has at the end thereof a crimp 340 which is formed so as to engage the overhanging portion of the head of the associated fastener 20, as shown in FIG. 1, when the connector blocks 10 and 14 are mated. The overhanging portions and the associated spring, therefore, form detenting elements. The interlocking of the connector blocks 10 and 14 by the engagement between the crimps 34c and the overhanging portion of the heads of fasteners 20 causes the housing 30 to abut against the panel 18 so as to provide for the connectors a continuous metal shield to thereby protect the circuits coupled by the connectors from receiving electrical pickup from external sources.

The housing 30 may advantageously be cast zinc and may include, as shown in FIG. 1, a cable clamping portion 38 which is utilized for clamping the cable 40, which will generally be of the type having a shielded covering. As shown in FIG. 1, cable 40 with its shielded covering is clamped by the clamping portion 38 attached to the housing 30 by machine screws 44.

Connectors of the type shown in FIG. 1 are frequently utilized to interconnect a plurality of electrical circuits. Therefore, the cable 40 will normally carry a number of wires going to one connector to be interconnected with a like number of wires leading from the other connector. The wires to each connector are connected to individual connector elements in the connector blocks which will upon the mating of connector blocks 11 and 14 be mated one to another.

From the connector elements in connector block 14, for example, a number of wires will normally be extended to circuit elements which may, for example, be mounted to the underside of panel 18, as where panel 18 is part of a chassis of an electronic amplifier. For simplicity the wires connected to terminal connector block 14 are not shown in FIG. 1.

V In FIG. 2 the housing 30 is shown in a position above panel 18 with the housing 30 not in abutting relationship with the surface of panel 18 and with the connector blocks and 14 disconnected or uncoupled. FIG. 2 also shows the flat spring elements 34 with their crimped ends 346 disengaged from the overhanging portion of the fasteners 20.

The connector blocks 10 and 14 are both designed in the illustrated arrangement of FIG. 2 to have a plurality of electrically conductive connector elements so that upon the mating of connector blocks 10 and 14 there is a mating of the corresponding connector elements to provide a coupling of the plurality of electrical circuits. For simplicity there is shown in FIG. 2, in phantom, one only of the plurality female connector elements required and one only of the male connector elements required to mate with the female elements.

In connector block 14 there is a plurality of holes each adapted to receive a male connector element such as the male connector element 50, shown in phantom. Male connector 50 has a male end 50a and a female end 50b. The male end 50a is designed for engagement with the associated female connector element of connector block 10 while the female portion 50b of connector element 50 is designed for receiving the male portion of a pin,

not shown, which would normally be used as a means for.

connecting a wire to the male connector element 50. The pin could, for example, be crimped to the wire'so a good electrical contact would be made between the wire and the pin. Upon insertion of the pin into the female por-' tion 50b of connector element 50, the wire would then be effectively connected to the male portion 50a of connector element 50.

The housing 3% in FIG. 2 is shown with a section broken away so that a portion of connector block 10 is visible. Connector block it would have a number of holes corresponding with the number in connector block 14.

Each of these holes is designed to receive a female connector element 54 having a female end 54a designed to receive the male end 50a of male connector element 50 and having another female end 54b designed to re ceive a pin of the type previously referred to as being a means for connecting a Wire to the male connector element 50. The pin which could be inserted into the female end 54b of female connector element 54 could be connected to one of the wires of the cable 40 by crimping the pin to the wire.

To mate the male end 50a of connector element 50 with the female end 54a of the female connector element 54 the housing 30 is positioned so that the male portion 11 of the connector block 10 is inserted into the female portion 15 of the connector block 14. As this coupling of the connector blocks 10 and 14 occurs the crimped ends 34c of the flat spring elements 34 engage the top portions of the heads of fasteners and upon the forcing of the housing into abutment with the surface of panel 18 the crimped ends 34c will first cam over the round top portion of the head of fastener 20 and then engage the underside of the overhanging portion as shown in FIG. 1. The heads of fasteners 20 therefore provide both a camming and locking surface respectively by virtue of the rounded top and the flat bottom.

When the housing 30 is abutted to the surface of panel 18 and the crimped ends 34c of the flat springs 34 engage the underside of the overhanging portion of the heads of fasteners 20 the housing 30 is interlocked with the panel 18 and the connector elements are interlocked so that connector elements 54 and 50 are maintained in electrical contact in avoidance of disengagement or dis-' connection of the contacts by accidental means. The engagement by the crimped ends 340 on the underside or bottom of the overhanging portion of the heads of fasteners 20 is normally sufficient to require for disen-' gagement an amount of force upon the housing 30 in a direction away from panel 13 which would not normally be applied by accident but would normally only occur when disengagement of the connector elements was de: sired.

One specific example of a design for the flat spring elements 34 which can be advantageously utilized would incorporate an angular relationship between the portion 34a and the portion 34b on the order of 88. The crimped end portion 34c could extend into the housing 30 away from the portion 34b by an amount which may, for example, be .028 inch. This amount of crimp has been found to be sufficient to provide satisfactory engagement and intercoupling of the fiat spring elements 34 with the heads of fasteners 20 to provide the necessary locking of the housing 39 to panel 18 to maintain a mating of the connector elements.

These dimensions are, of course, exemplary only of a particular design which has been found to be effective.

It will be evident to those skilled in the art that there disclosed. a

The particular interlocking means shown in FIGS. 1 and 2 by which the flat spring element engages the head of fastener 26 and therefore acts as a retainer for main taining the housing 30 in abutting relationship with panel 18 is advantageous in that it utilizes the fastener 20 for both the purpose of holding the connector block 14 in fixed relationship with panel 18 and to provide a detenting element by virtue of the overhanging portion of the head of fasteners 20 thus making it unnecessary that the connector block 14 be designed to include a detent element which could be engaged by an interlocking retainer spring such as spring 34.
