FIG. 12 is a top view of the insulator body shown in FIGS. 10 and 11.
DESCRIPTION OF THE SPECIFIC EMBODIMENTS Referring to FIGS. [-4, the insulator assembly 10 of the invention is shown, comprising a body member 11 and a spring clip 12 mounted on a metal fence post 13 in the form of a rod of circular cross-section. The body member 11 is molded from a plastic material and comprises a sleeve 14 comprised of a support web 15 having wire- engaging hooks 16 and 17 integrally mounted thereon, and a channel-forming web 18 cooperating with the support web 15 to define a channel 19. The hooks are of a form previously known in the art. A wire 20 is supported and restrained by the hooks I6 and 17. The spring clip 12 is provided with apertures 21 and 22 for receiving and engaging the post 13. The apertures 21 and 22 are provided with serrations 23 and 24 for preventing rotational movement of the spring clip 12.
In mounting the insulator on a post, the spring clip l2 is first inserted through the channel 19 of the sleeve 14. The spring clip 12 is then bowed by compressing the ends together and mounted on the fence post 13 with the fence post disposed within the apertures 21 and 22. When the ends of the clip are released, the resilience of the spring clip causes it to engage the fence post with considerable force and to maintain the insulator in position. The serrations 23 and 24 prevent the spring clip from revolving about the fence post. The bowing of the spring clip also causes the sleeve 14 to be frictionally engaged by the spring clip 12 and the insulator is thereby prevented from sliding along the spring clip.
The body member may be molded of any suitable plastic such as linear polyethylene, polypropylene, polyvinyl chloride, polyurethane, polycarbonate, nylon, and other plastic materials such as artificial or natural rubber. The spring clip 12 may be made of any suitable material such as steel or other metals providing sufficient resilience to maintain the clip engaged with the pole. It may also be made of suitable plastic materials.
Referring to FIGS. 5 and 6, another embodiment of the invention is shown with the insulator comprising a body member 25 having a core 26 with transverse flanges 27 and 28 integral therewith. The insulator 25 additionally includes an integral loop 29 mounted on the support web flange 27 cooperating to form a channel 30 for receiving and engaging a spring clip such as that designated by the numeral 12 in FIG. 1, and wireengaging hooks 31 and 32 defining with the core 26 a wire-receiving channel 33.
The insulator of FIGS. 4 and 5 is mounted in a manner similar to that of FIGS. 1-4. A spring clip 12 is inserted into the channel 30 defined by the loop 29 and flange 27. The spring clip is bowed and placed over a fence post in a manner similar to that shown in FIG. 1.
FIG. 7 illustrates a spring clip 34 which may be utilized with either of the insulator bodies shown in FIGS. 1-6. The spring clip 34 is provided with apertures 35 and 36 contoured to receive a round post, and having serrations 37 and 38 to restrain the spring clip 34 from rotating about the fence post. Additionally, a detent aperture 39 is provided for engaging a detent protuberance 41 provided in the insulator body 60 shown in FIGS. 11 and 12.
' FIG. 8 illustrates a spring clip 42 having apertures 43 and 44 so cut as to permit the spring clip to be utilized with fence posts having either a T-form cross-section or an angle cross-section. A fence post 45 having a T-form cross-section is shown positioned in the aperture 43. A detent aperture 46 is provided for use with a detent protuberance 41 such as shown in FIGS. 11 and 12.
FIG. 9 illustrates an insulator body as shown in FIGS. 1-4, utilizing a spring clip 42 as shown in FIG. 8, and mounted on an angle post 50. In order to clear the lugs 51 as the clip is being mounted, slots 52 and 53 are provided in the apertures 43 and 44. Additionally, slots 54 and 55 (FIG. 8) are provided to engage the angle leg of an angle post, and slots 56 and 57 are provided to clear the leg of a T-form post.
Referring to FIGS. -12, still another embodiment of the invention is shown having a body member 60 comprising a support web in the form of a flange 61. Instead of being formed as a sleeve as in FIGS. 1-9, angle flanges 62 and 63 are formed as extensions of the flange 61 and define therewith a channel 64 adapted to receive and retain a spring clip such as shown in FIGS. 7 and 8. A detent protuberance 41 is provided to engage the apertures 39 or 46 in order to prevent the spring clip 34 or 42 from sliding. Additionally, wireretaininghooks 65 and 66 are mounted on the support web or front face of the flange 61.
The insulator of the present invention is assembled and mounted by taking a spring clip such as shown in FIGS. 7 or 8 and sliding it into channels 19, 30 or 64 of the insulator bodies 11, 25 or 60, respectively. If a detent protuberance 41 is utilized, it is inserted in. the apertures 39 or 46. The spring clip is then bowed and mounted over the fence post with thepost disposed in the apertures 35 and 36 (FIG. 7), or 43 and 44 (FIG. 8). The bowing of the spring clip provides a spring force which engages the body member and prevents it from sliding during use. The insulator body then becomes firmly affixed to the fence post. If desired, serrations 23 and 24 or 37 and 38 maybe provided to prevent the insulator assembly from rotating about the fence post. The use of the protuberance 41 in combination with the apertures 39 and 46 may be desirable in certain cases but may generally be dispensed with.
The spring clip insulator of the present invention has a number of advantages over prior art insulators. First,
The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:
1. An electrical insulator comprising a body member having a support web, means cooperating with said support web defining a channel on one side of said support web, and wire-engaging and supporting means mounted on another side of said support web, and an elongated strap-form spring clip having an aperture at each end for mounting over a post disposed and retained within the channel of said body member.
2. An electrical insulator body member according to claim 1, wherein said support web and said means cooperating therewith form a continuous sleeve defining said channel therein.
