2 Claims. (01. 173-328) This invention relates to electrical connectors and more particularly to electrical connectors of the panel mountable and separable part type.
It is an object of the present invention to provide in an electrical disconnect connector having parts sealed with respect to one another in an air tight manner and adapted to be sealed in a panel opening wherein the insulating parts. containing male and female terminal elements can, upon the surrounding metal containing parts being released, be backed off from one another by the turning of a single coupling screw adapted to tighten the parts and draw them together and upon the turning of the screw in the opposite direction cause the backing oil of one of the parts from the other, the other part remainingfixed upon the panel mounting and still sealed to prevent the leakage of air through the panel opening.
It is another object of the present invention to provide an electrical connector adapted for mounting upon a panel in an air tight manner with a seal being disposed between joined parts and which includes casing parts wherein a casing part receiving the lead-in wires which connect with the terminal contacts in one of the insulating parts can be adjusted upon a fixed casing part and turned at an angle with respect to the other casing part and such that the cable wires can lead from any one of a great number of angular directions from the connector, by the simple removal of a spring ring having specially formed axially extending projections which can be brought toward one another to release the ring and thereby to release the casing part upon the other casing part so that the adjustment can be effected and the engaging and retaining teeth on the one casing part entering different teeth on the other casing part which is fixed and wherein thereafter the adjustment has been made the spring ringcan be easily put in place to hold the parts tightly coupled, the access to the spring ring being effected by the simple removal of a cover or plug part on the one casing part.
Other objects of the present invention are to provide an electrical connector of the separable and panel mountable type which is of simple construction, inexpensive to manufacture, easy to mount upon the panel, wherein the parts are sealed with respect to one another, has a minimum number of parts, compact, rugged, wherein the parts can be separated from one another and adjusted easily and quickly and efiicient in operation.
For other objects and for a better understanding of the invention, reference maybe had to the following detailed description taken in connection with the accompanying drawing, in which Fig. 1 is a longitudinal sectional view of the connector embodying the features of the present invention mounted upon a panel board, the view being taken generally on line l-l of Fig. 2 and locking in the direction of the arrows thereof.
Fig. 2 is an end elevational view of the connector. l i
Fig. 3 is an enlarged perspective and sectional view of certain of the parts of the connector and showing in particular the coupling and backing off screw arrangement.
Fig. 4 is a perspective view of the casing parts which can be angularly adjusted with respect to one another with portions broken away to show the peripheral teeth upon the parts which mesh with one another upon the angular adjustment of the one casing part being made with respect to the other casin part.
Fig. 5 is a transverse sectional view taken generally on line 5-5 of Fig. l and looking in the direction of the arrows thereof with portions being broken away to show the teeth upon the other casing part. l 7
Fig. 6 is a perspective view of the spring ring which serves to retain the casing parts after the angular adjustment of the same has been effected, the ring having axially extending projections which can be easily grasped with-pliers to contract the spring for the effecting of its removal from the groove of the one casing part and from its retaining position.
Referring now to the figures, l0 represents a panel on which the connector is mounted. This panel has an opening II for receiving an outer shell [2. This outer shell is provided with a shoulder l3 which contains a gasket 14 adapted to have sealing engagement with one face of the panel [0. This shell I2 is threaded at 15 to receive a nut l6 which enters a recess in the opposite face of the panel which secures firmly the shell l2 to the panel l0 and within the opening ll thereof. M
This shell [2 supports an insulating part I! containing a plurality of circumferentially spaced female terminal contacts I8 and a central internally threaded ground terminal [9. The shell part I2 has internallyextending flange 2| against which the insulating member I7 is brought and retained by an internally threaded retaining ring 22 connected to threads 23 of the shellpart H. A sealing grommet 24 is disposed between the insulating member I1 and the flange 2| of the outer shell [2.
of one shell with respect. to: the'other.
3 Each female contact I8 is shouldered at and held against a sealing ring 26 by a small spring retaining clip 21. The contact will have the usual projection 28 to which a cable wire can be soldered;
The central, groundi contact; is,- shoulderedijas.
indicated at 29, and this shoulder bears against a seal 30 in the insulating member ll. The ter minal contact [9 is held in place in the insulating member I! by a retaining nut 31-. A- portion; 32' is provided on the terminal for receiving'a cable wire. This terminal [9 is internallythreaded -as indicated at 33, to receive, a coupling screw. 34'
which has a flange 35 and adapted tobear against the end of the terminal l9 when all ortheparts of the connector are in full coupled relationship,

The plug 42 has an inwardly extending sleeve projection 62 which contains the securing and backing. oft,v screw 34. Within the sleeve: projection is; a; shoulder 63, Eig'. 3, against which a shouldered portion of the screw 34 reacts to effect the backing off action of the male contact assembly 36, The shoulder on the screw is indicated at: (it. The inner end of the sleeve projection 62 is sealed upon the insulating member 39 by seal -65; 'Ilheinsulatinemember 39 has a large openins-E6; :w-hichv receives the internally threaded central terminall and coupling member l9 secured to the insulaiting' part :1.
The screw 3 i has a nut 61, Fig. 3, for fixing it: tothe plug 42 In order to prevent the nut 61 from becoming detached, the end of the screw itselfis-upset, as indicated at 68, or provided with solder or such other suitable means as to make certain. of the ooupledrelationship or the: screw 34 with-:the' plug; 42 The screw. 3'4" is journalledin theplug so i that it. can be: turned therein; to eiiect the. coupling" of! the male: contact assembly with. the female contact assembly; Upon the reverse: turning motion-of the; screw. the. screw 34' with: the pants: assembled? thereon. and: including the male contact M; will-beevenly hacked oil; from the female contacta assembly:
