4 Claims. (Cl. 339-94) 7 This invention relates to a waterproof, sealed jack assembly.
Open jack assemblies which may be subject to the collection of moisture, are frequently sources of break down in electrical systems of which the jacks are a component.
Accordingly, an object of this invention is to provide an improved jack assembly which is sealed in a manner to prevent ingress of moisture and deposition of the same on the contact members.
A further object of this invention is to provide in a jack assembly of the character described, a casing for the jack. in combination with sealing means at the plug opening thereof and sealing means at the terminal end thereof.
Other objects of this invention will in part be obvious and in part hereinafter pointed out.
The invention accordingly consists in the elements of construction and arrangement of parts as exemplified in the embodiment hereinafter described and of which the scope of invention is set forth in the claims following.
Referring to the drawing:
Fig. 1 is a front elevational view of a sealed jack assembly embodying the invention;
Fig. 2 is a vertical sectional view with parts removed;
Fig. 3 is a vertical elevational view thereof with the casing in section and the assembly rotated about a vertical axis to another position; and
Fig. 4 is a view similar to that of Fig. 3 with the assembly rotated to still another position and with parts omitted.
Referring in detail to the drawing, sealed jack assembly embodying the invention. The same comprises a jack of the telephone type, generally designated at 11 and a sealing casing therefore, generally designated at 12.
The jack 11 is made up of a plurality of contact members, for the purpose of illustration, being shown as two in number, 13, 14. Member 13 extends from a ring portion 15 disposed in alignment with a ring portion 16 from which member 14 extends. A third ring 17 is aligned with ring portions 15, 16, insulating rings 18 being disposed to separate the portions from one another. The ring portions and rings are gripped together by means of a metal bushing 19 which is upset at one end thereof and has an annular flange or collar 20 in engagement with ring portion 17. The bushing 19 is externally threaded as at 21.
Extending from ring portions 15, 16, 17 are soldering lugs 22, 23, 24, respectively. The contact members 13, 14 have bent up contact portions 25, 26, respectively, such contact portions being axially aligned with bushing 19 and angularly related to each other.
The jack 11 has assembled therewith a disc closure member made up of an inner layer 27 of; phenolic resin material and an outer layer 28 of resilient synthetic plastic material, such as neoprene, silicone rubber or the designates a like, the phenolic resin imparting stiffness to the disc as a whole. Terminal wires 29 are soldered at one end thereof to the lugs 22, 23, 24 and pass through openings formed in the closure member. Eyelets 30 are fixed in the openings of the closure member and solder 31 is applied to each eyelet to seal the terminal wire passing therethrough. Thus, the closure member is mounted in suitably spaced relation to the aligned ring portions and maintained in such position by the terminal wires 29 which may be of suitable stiffness.
The thus mounted jack 11 is positioned within the casing 12, with the threaded portion of the bushing 19 projecting through a central opening 32 formed in end wall 33 of the casing. A sealing gasket 34 of silicone rubber, neoprene or the like is located on the bushing 19 between the flange 20 thereof and the inner surface of the casing wall 33.
The side Wall of casing 12 is formed with an annular groove or indentation 35 slightly spaced from the outer or open end thereof, to provide a seat for the periphery of the disc closure. The end of the casing side Wall is then spun over as at 36 to engage the outer layer 28 of the closure. Such spinning operation is designed also to tightly press the forward end of the jack 11 at flange 20 against the casing Wall 33 with gasket 34 compressed therebetween to effectively seal the opening 32 in the casing.
The outer ends of the terminal wires 29 which project through the closure may be formed with eyes to provide external soldering connections.
It is understood that the jack may be made up of any selected number of contact members with corresponding lugs and terminal wires soldered thereto and brought out through the closure disc, as described.
The casing 12 may be formed of thin metal or other suitable material and provides protection against the ingress of water, the same being sealed at its forward end by the gasket 34 and at its rear end by the resilient outer layer 28 of the closure disc, such resilient layer being supported on the stiff inner layer 27 of the disc.
Having thus disclosed our invention, we claim as new and desire to protect by Letters Patent:
1. A sealed jack assembly comprising a tubular casing having an end wall at one end thereof formed with a central opening and open at the other end thereof, a jack Within said casing comprising a flanged bushing and a plurality of insulated contact members mounted on one end of said bushing with contact portions of said members axially aligned with said bushing, the other end of said bushing projecting through the opening in said casing end wall, a resilient gasket on said bushing between the flange thereof and the inner surface of said casing end wall, a stiff insulating closure member at the open end of said casing, stiffened terminal means extending from each of said contact members through said closure member and sealed thereto, the peripheral end portions of said casing being in sealed relation to said closure member and pressing said jack toward the casing end wall to compress said gasket and thereby seal the opening in said casing end wall.
2. A jack assembly as in claim 1, wherein said closure member comprises an inner layer of stiff synthetic resin and an outer layer of resilient synthetic resin.
3. A sealed jack assembly comprising a tubular casing having an end wall at one end thereof formed with a central opening and open at the other end thereof, a jack Within said casing comprising a bushing having a radial flange intermediate the ends thereof, a plurality of conductive ring members mounted on said bushing with interleaving insulating members, a contact member extending from each of said conductive ring members with a portion thereof arranged in aligned relation to the axis of said bushing, a stiff closure disc for the open end of said casing, stiff terminal means extending from each of said ring members through said closure disc, means for sealing each terminal means to said disc, a portion of said bushing extending through the opening in said casing wall, a synthetic rubber gasket on said bushing between the fiange thereof and said casing end wall, said casing having the annular edge portion at the open end thereof in sealed relation to said closure disc and pressing said jack toward said casing end wall to compress said gasket, thereby sealing the opening in said casing end wall.
4. A jack assembly as in claim 3, wherein said closure disc is formed with openings through which said terminal means extends, an eyelet in each opening and a solder seal between each eyelet and the terminal means passing therethrough for fixing the position of said jack relative to said disc.
