Application February 2'7, 1941, Serial No. 380,917
2 Claims. (01. 173-334) This invention relates to new and useful improvements in electrical connectors and more particularly to a plug, the principal object of the same being to provide a plug of sectional construction permitting ready detachability of parts for the purpose of making electrical connections to the binding means therein.
Another important object of the invention is to provide an electric plug wherein the parts are so interconnected as to permit assembly at low labor cost.
Other objects and advantages of the invention will become apparent to the reader of the following specification.
In the drawings:
Figure 1 represents a side elevational view of the plug.
Figure 2 is a sectional view taken substantially on the line 2-2 of Figure 1.
Figure 3 is a fragmentary longitudinal sectional view through the plug.
Figure 4 is an end elevational view looking at the prong end thereof.
Figure 5 is a fragmentary side elevational view showing the insert section.
Figure 6 is an edge elevational view of the insert section.
Figure 7 is a perspective view of one of the prongs.
Figure 8 is a perspective view of one of the prong retainers.
Referring to the drawings wherein like numerals designate like parts, it can be seen that the plug consists of a block 5 of insulation having a substantially rectangular-shaped pocket 6 therein. Numeral 1 denotes a relatively thin insert section for the block 5, the same provided with a reduced knob formation 8.
The insert section I has a reduced heart-shaped formation 9 projecting therefrom and into the pocket 6 and at each of its side edge portions is an arcuate-shaped spring I!) having a hump II at its intermediate portion. Each of the springs H] has a leg portion 12 apertured to receive an anchored bushing 13 and a screw l4 disposed therethrough. At the point where the section 1 merges with the heart-shaped formation 9, an opening 15 is located, this representing the lower end of a passageway 16 which extends longitudinally through the section 1 and through the knob 8 to accommodate a conductor cord H, the conductors of which are connected in place by the screws I4.
Slots l8 extend through the bottom of the block A pair of L- shaped members 20, 20 are provided in the pocket 6, setting in the lower corners thereof and each upstanding portion thereof has a recess 2| for receiving the hump ll of the corresponding spring lll.
As can be seen in Figures 3 and '7, each L-shaped member 20 has a leg 22 depending therefrom, the upper portion of which being serrated or corrugated as at 23 for meshed relation with a correspondingly formed upstanding portion 24 of an angle member 25, these angle members being secured to the block 5 seated in the recesses l9.
While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.
Having described the invention, what is claimed as new is:
1. In a connector of the character described, a block having a pocket therein, said block having an opening through one end thereof and opening into the bottom of the pocket, an elongated contact prong having a portion extending through the opening, an angularly shaped contact element at the inner end of the prong, said prong being provided with corrugations at one side thereof and a detent secured to the block and adapted to engage between certain corrugations to retain the prong fixed to the block, said detent consisting of an angularly shaped member, securing means for removably securing one end portion of the member to the block, the other end portion.
of the member being provided with corrugations and extending into the opening to mesh with the corrugations of the prong.
2. In an electrical connector, a block provided with a rectangular socket therein for receiving a plug having a pair of plug-in contacts, said block having a bottom provided with a pair of openings therein spaced inwardly from opposite sides of said socket, respectively, a pair of elongated prongs extending out of said socket through said openings, respectively, and having right angled inner ends fitting in bottom corners of said socket and extending along said opposite sides of the latter for receiving said pair of plug in contacts therebetween, and a pair of right angled detents fixed in said bottom and having serrated ends disposed in said openings alongside said prongs and bearing against the same to hold the prongs in place.
