FIELD OF THE INVENTION

The present invention relates to wire clamping assembly, and in particularly, a well pump wire clamp for holding wires to the well pipe and keeps the wiring centered in the well casing.

BACKGROUND OF THE INVENTION

If you live in a town or city, you probably don't give much thought to how the water you use each day gets to your house. Even small villages often provide a network of supply pipes that transport water to each home in the neighborhood. All you need to know is how to open the tap at the sink.

Move a few miles out of town and the picture can change. While the inner workings are still thankfully invisible, your water supply is independent from the neighbor's down the road. Each home has its own well from which to draw water. More than that, each home has its own electromechanical system for getting the water from the well to the house. At the heart of each system is a pump, and the most common types are jet pumps and submersible pumps.

Wells get drilled as far down as 1,000 feet into the rock to access the water. Water travels through this casing via a well pump. The well pump, by far one of the most important elements of any well system, the well pump is what works to suck the water up from out of the ground and then send it on its way into the pipes of your home. Casing provides support for the wall of the well so that loose rock fragments or unconsolidated sand and gravel through which the well has penetrated do not collapse into the well shaft. The casing protects the electrical wires, pull cable and water tubing/piping that are connected to the submersible pump.

Conventional wire clamps have been used to mount wire to surfaces. However, such wire clamps typically employ a metal strap to engage the wire. Improper installation or movement of the cable may cause the edge of the metal strap to cut through the cable jacket exposing interior wires to weather, water and humidity. Plastic tie wraps have also been used to mount wires to surfaces. However, tie wraps have limited pull-out strength characteristics and are not readily reusable.

Electrical tape is the most common attachment of the wires to the well pipe however Inadequate taping, poor support of the wire en route down the well, usually taped to piping, wire may not be taped sufficiently strongly or not tapes securely along the full drop of piping in the well. This is probably the most-common cause of broken or damaged pump wiring.

Wire clamps must often be applied to the pipe section in difficult conditions, and it is also important that each clamp can be applied quickly and reliably. Well pump wiring loose in the well casing invites abrasion damage, tears, breaks inside to the pump wires causing the well pump to stop working.

BRIEF DESCRIPTION OF THE INVENTION

The primary object of the present invention is to provide well pump wire clamp for attachment to well pipes that keeps the wiring strongly secure along the full drop of piping in the well casing substantially eliminates or reduces disadvantages and problems associated with prior devices.

In order to achieve this aspect, the well pump wire clamp for protecting a wire in a well casing includes a first clamping member and a second clamping member configured for interlocking around the outer surface of the pump pipe sandwiching the wire there between.

In accordance with the present invention, each interlocking member includes a locking mechanism with a predetermined number of teeth for securely fastening both members to each other allowing the contact area between the wires and pipe to be maximized, thru affording the best possible grip on the wires and pipe.

The first clamp member includes a tapered tongue with a predetermined number of teeth and is adapted for insertion into the elongated opening head and meshing with the racket arm of the second clamp member. In addition, a U-shaped groove located on the inner surface of the first clamp member is provided to accommodate one or more wires having the same or different sizes to be held securely by the well pump wire clamp.

The second clamp member includes a head portion forming a substantially cavity opening and whereas the ratchet arm with a predetermined number of teeth engages the first interlocking member tapered tongue so as for tightening and locking together both members.

In yet another aspect of the invention, both clamp members are provided with a profiled surface guard adapted to engage the inner walls of the well casing protecting and preventing excessive or abnormal abraded and worn wire by rubbing on well casing, piping, and other contact surface.

These and other features and advantages of the invention will be readily apparent from the following detail description of an embodiment thereof and reference to the accompanying drawings.

DESCRIPTION OF CERTAIN EMBODIMENT OF THE PRESENT INVENTION

In the following detailed description of the preferred embodiment, reference is made to the accompanying drawings, which form a part of this application. The drawings show, by way of illustration, specific embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present invention. assembly.

The present invention shown in FIG. 1 illustrate the well pump wire clamp 10 specifically designed to mount well pump wire cable 14 to drop pipe 13 located in the well casing (not shown). The well pump wire clamp generally comprises a first clamping member 11 and a second clamping member 12 configured for interlocking around the outer surface of the drop pipe 13 keeping the wire cable 14 safe from breakage.

As shown in FIG. 2, is a front view of the well pump wire clamp 10 comprises a first clamp member 11 and a second clamp member 12 together in a closed position about a drop pipe 13 and the wire cable 14 engaging the interlocking mechanism 16 by way of the tapered tongue 17 and the second clamp member head 15.

More specifically, as shown in FIG. 3, a front view of the well pump wire clamp 10 showing first clamp member and a second clamp member 11, 12 respectively, located around the drop pipe 13 and wire cable 14 in the open position before engaging the interlocking mechanism 16. The first clamp member 11 includes a U-shaped groove 20 wide enough for engaging the wire cable 14 and the tongue teeth 18 located on the tapered tongue 17 when inserted into the head 15 will then engage the ratchet arm 28. The inner circumferential clamp surface 23 is slightly modified by including a wire pipe rib 21 to the first clamp member 11 and a pipe rib 27 to the second clamp member 12 formed longitudinally along the inner circumferential clamp surface 23. When the well pump wire clamp 10 is in a clamped position, the inner circumferential clamp surface 23 and both pipe rib 21,27 in engage and prevent the separation or disengaging of the well pump wire clamp 10 from any skewing action. the second clamp member 12 is similar to the first clamp member 11 wherein both members include an outer guard 22 for the preventing excessive or abnormal drop pipe 13 torqueing or twisting when the pump (not shown) starts and stops. Another similarly to the first clamp member 11 wherein a protruding pipe rib 27 is formed on the inner circumferential clamp surface 23 and extent lengthwise with respect to the engaging the drop pipe 13 locking the clamp in place.

As shown in FIG. 4, is a cut-a-way top view of the second clamp member 12 having an cavity opening 25 with a guide slot 26 located in the head 15 designed for the tapered tongue 17 (not shown) to be inserted for engaging the ratchet arm 28.

More specifically, as shown in FIG. 6 a sectional view of the well pump wire clamp 10 engaged in a clamping position. The operation and structure the interlocking mechanism 16 made up of first clamp member 11 and a second clamp member 12 component pieces each of substantially identical to FIG. 1. The first clamp member 11 includes a tapered tongue 17 with a predetermined number of teeth 18 and a guide rail 19 is adapted for insertion into the second clamp member 12 cavity opening 25 meshing with the ratchet arm 28. Once the tongue teeth 17 and the ratchet teeth 29 become engaged 30 in the locking position.
